Description

Technical Field

[0001] This invention relates to a guide clamp. Background Technology

[0002] An apparatus is proposed, which is configured to insert a second clamp into a guide through hole of a first clamp and insert the second clamp toward the corresponding part (the part where grease needs to be supplied from the tip of the grease supply tube) until the tip of the grease supply tube provided in the second clamp and the corresponding part are in a predetermined positional relationship (for example, see Japanese Patent Application Laid-Open 2020-37949).

[0003] However, Japanese Patent Application Publication No. 2020-37949 does not specifically describe the situation where the first clamp is engaged (fixed) to the engaging object in a positioned state relative to the engaging object. There is room for further research. Summary of the Invention

[0004] The present invention provides a guide clamp (e.g., a first clamp) that engages (fixes) the engaging object in a positioned state relative to the engaging object.

[0005] The present invention relates to a guide clamp having a guide clamp body and an engaging portion. The engaging portion is provided in the guide clamp body and configured to engage with the engaging object when the guide clamp body is positioned relative to the engaging object. Furthermore, the guide clamp body has a guiding through hole extending toward a corresponding portion when the engaging portion is engaged with the engaging object, and is configured to guide the insertion direction of an insertion portion inserted into the through hole and toward the corresponding portion. The engaging portion includes at least two protrusions. The at least two protrusions are arranged in a row toward the insertion direction. The interval between adjacent protrusions of the at least two protrusions is set to a length corresponding to the thickness of the engaging object.

[0006] According to the guide clamp described above, a guide clamp (e.g., a first clamp) can be provided that engages (fixes) the engaging object in a state in which the engaging object is positioned relative to the engaging object.

[0007] This is because at least two protrusions are arranged in a row facing the insertion direction, and the spacing between adjacent protrusions in the at least two protrusions is set to a length corresponding to the thickness of the engaging object.

[0008] Furthermore, in the guide clamp of the above-mentioned scheme, the engaging portion may include at least three protrusions, which are arranged in a row facing the insertion direction, and the intervals between adjacent protrusions among the at least three protrusions are set to be of different lengths.

[0009] Furthermore, in the guide clamp configured as described above, the protrusion length of the protrusion located at both ends in the insertion direction of the at least three protrusions may be longer than that of the other protrusions.

[0010] Furthermore, in the guide clamp of the above-described scheme, the spacing between adjacent protrusions of the at least two protrusions may widen as they approach the tip of the protrusion.

[0011] Furthermore, in the guide clamp constructed as described above, one of the adjacent protrusions may be inclined relative to the other protrusion.

[0012] Furthermore, in the guide clamp configured as described above, a slotting process may be performed on one or the other of the adjacent protrusions to allow at least a portion of the engaging object inserted into the interval to abut against it.

[0013] According to the present invention, a guide clamp (e.g., a first clamp) can be provided that engages (fixes) the engaging object in a state in which the engaging object is positioned relative to the engaging object. Attached Figure Description

[0055] Hereinafter, the grease supply device for the clutch disengagement mechanism will be described in detail with reference to the accompanying drawings as the first embodiment of the present invention. It should be noted that the present invention is not limited to the embodiments described below.

[0056] The grease supply device of the first embodiment of the present invention will be described below. The grease supply device of the first embodiment is used to perform maintenance and grease injection for poor sliding caused by grease leakage from the grease lubrication part of the shift fork in the MT (manual transmission) clutch housing and the introduction of foreign matter after the manual transmission vehicle has been submerged in water / crossed a river, so as to perform maintenance at low cost and in a short time.

[0057] Figure 1 This is a schematic diagram illustrating the clutch disengagement mechanism of the first embodiment. (As shown) Figure 1 As shown, the clutch device 1 is configured to include: a clutch body 10 for connecting / disconnecting power; a clutch disengagement mechanism 20 for operating the clutch body 10; and a clutch housing 30 for housing the clutch body 10. For example, the clutch device 1 is mounted on a manual transmission vehicle and is positioned between the engine and the transmission.

[0058] It should be noted that, Figure 1 The X direction, as shown, represents the axial direction along the central axis, and the Z direction represents the direction orthogonal to the central axis (sometimes referred to as the radial or height direction). When the Z direction is set as the height direction, the upper side is sometimes referred to as the top end side, and the lower side as the base end side. Furthermore, the Y direction, described later, represents the direction orthogonal to both the X and Z directions. Sometimes the Y direction is referred to as the width direction.

[0059] The clutch body 10 includes a clutch disc 11, a clutch cover 12, a pressure plate 13, a diaphragm spring 14, and a release bearing 15.

[0060] The clutch disc 11 has a friction surface (clutch facing) sandwiched between the pressure plate 13 and the flywheel 16, and the clutch disc 11 is splinedly engaged with the input shaft 3 of the transmission. The rotation of the flywheel 16 is transmitted to the input shaft 3 through the friction between the friction surface of the clutch disc 11 and the flywheel 16. The flywheel 16 is bolted to the crankshaft 2 of the engine, and the flywheel 16 rotates integrally with the crankshaft 2.

[0061] The clutch cover 12 is configured to cover the outer periphery of the clutch disc 11 and rotates integrally with the pressure plate 13 and the diaphragm spring 14. The pressure plate 13 is located between the friction surface of the clutch disc 11 and the diaphragm spring 14. The diaphragm spring 14 is a component used to press the friction surface of the clutch disc 11 toward the flywheel 16 via the pressure plate 13, and is located on the opposite side of the friction surface of the clutch disc 11 relative to the pressure plate 13. The periphery of the diaphragm spring 14 is connected to the pressure plate 13, and the central portion of the diaphragm spring 14 is connected to the release bearing 15. Thus, the diaphragm spring 14 can press against the pressure plate 13.

[0062] When the clutch body 10 is engaged, the pressure plate 13 uses the elastic force of the diaphragm spring 14 to press the friction surface of the clutch disc 11 toward the flywheel 16. This generates friction between the friction surface of the clutch disc 11 and the flywheel 16, thus transmitting the rotation of the flywheel 16 to the clutch disc 11 in the engaged state.

[0063] When the clutch body 10 is disengaged, the release bearing 15 pushes the center of the diaphragm spring 14, thereby displacing the periphery of the diaphragm spring 14 away from the flywheel 16. At this time, the pressure plate 13 and the diaphragm spring 14 are pulled together away from the flywheel 16. As a result, the friction between the friction surface of the clutch disc 11 and the flywheel 16 is eliminated, thus achieving the disengaged state where the rotation of the flywheel 16 is not transmitted to the clutch disc 11.

[0064] The clutch disengagement mechanism 20 includes a clutch disengagement fork 21, a disengagement fork support 22, and a release cylinder 23.

[0065] The clutch release fork 21 is a component for axially moving the release bearing 15 and is configured to rock while supported by the release fork support 22. The clutch release fork 21 is an elongated metal component with a configuration where the top side is divided into two strands.

[0066] like Figure 1As shown, one end of the clutch release fork 21 is composed of a pressing portion 21a that presses against the release bearing 15 axially. The pressing portion 21a is configured with a two-pronged structure, with its top end divided into two branches, to clamp the input shaft 3 inside the clutch housing 30. The portion of the pressing portion 21a that faces the release bearing 15 axially (the abutting portion) contacts the release bearing 15. The other end of the clutch release fork 21 is composed of a connecting portion 21b, which protrudes outward from the clutch housing 30 via a through hole 31 and is connected to the release cylinder 23. Furthermore, the other end of the clutch release fork 21 is covered by a fork boot 32 at the position where it extends outward from the clutch housing 30. The fork boot 32 is fitted into the through hole 31. A hole (cooling hole) may also be provided in the fork boot 32 for releasing the frictional heat generated when the clutch body 10 is in a semi-engaged state to the outside of the clutch housing 30.

[0067] Furthermore, the clutch release fork 21 has a fulcrum portion 21c supported by the release fork support member 22 between the pressing portion 21a and the connecting portion 21b. The release fork support member 22 consists of a main body portion fixed to the partition wall of the clutch housing 30 and a pivot portion (not shown) with a spherical surface at the top end of the main body portion. The partition wall of the clutch housing 30 is composed of a retainer fitted with a bearing (not shown) that supports the input shaft 3. The retainer is a component fixed to the clutch housing 30. The root side of the release fork support member 22 is bolted to the retainer. In addition, inside the clutch housing 30, the boss portion 30a of the retainer extends along the input shaft 3. The input shaft 3 is inserted through the inside of the boss portion 30a.

[0068] The release bearing 15 is configured to move axially relative to the boss 30a while being supported on the outer periphery of the boss 30a via a sleeve. The release bearing 15 is configured to contact the central portion of the diaphragm spring 14. The release bearing 15 has: an outer ring supported on the boss 30a by the sleeve; and an inner ring that contacts the central portion of the diaphragm spring 14. In the release bearing 15, the inner ring that contacts the diaphragm spring 14 rotates, while the outer ring that contacts the clutch release fork 21 does not rotate.

[0069] Furthermore, when the driver depresses the clutch pedal (not shown), the release cylinder 23 operates. When the connecting part 21b is operated by the release cylinder 23, the clutch release fork 21 swings around the fulcrum part 21c. Through this swinging, the pressing part 21a presses the release bearing 15, causing the release bearing 15 to move axially and push the central part of the diaphragm spring 14 towards the flywheel 16, thereby disengaging the clutch body 10. When the clutch body 10 is disengaged, the flywheel 16 and the clutch disc 11 are disconnected, preventing power transmission. When the operating force from the release cylinder 23 is released, there is no longer a pressing force from the pressing part 21a acting on the release bearing 15, thereby engaging the clutch body 10. When the clutch body 10 is engaged, the flywheel 16 and the clutch disc 11 are connected, enabling power transmission. Thus, by swinging the clutch release fork 21, the connection and disconnection of the power transmission path between the crankshaft 2 on the engine side and the input shaft 3 on the transmission side are achieved.

[0070] Next, the grease supply device 100 of the first embodiment will be described. The grease supply device 100 is a device that supplies grease to the contact portion between the pressing part 21a of the clutch release fork 21 and the release bearing 15. The grease supply device 100 is configured such that: a second clamp 120 (insertion part 121) is inserted into the guide through hole (first hole 113, second hole 114) of the first clamp 110, which is fixed to the clutch housing 30 as described later, and the second clamp 120 (insertion part 121) is inserted toward the corresponding part C until the top end 131 of the grease supply pipe 130 provided in the second clamp 120 and the corresponding part C are in a predetermined positional relationship. Figure 1 As shown, corresponding part C refers to the contact portion between the clutch release fork 21 (pressing part 21a), which is a grease-requiring part (the part that needs to be supplied with lubricating grease from the top end 131 of the grease supply pipe 130), and the release bearing 15. Figure 1 As shown, the corresponding part C is disposed in the internal space surrounded by the clutch housing 30 (an example of the cover member of the present invention). A through hole (through hole 31) for clamp fixing is formed in the clutch housing 30, which communicates with the internal space.

[0071] When using a vehicle equipped with a clutch device 1 in environments containing sand, mud, or other pollutants, foreign objects may sometimes enter the clutch housing 30 through the cooling holes of the fork sleeve 32, the cooling holes provided in the clutch housing 30, or the drainage openings (none shown). Therefore, it is ideal to perform grease supply maintenance on the clutch disengagement mechanism 20 and to add grease to the contact portion between the clutch disengagement fork 21 and the release bearing 15. Therefore, the grease supply device 100 is configured to perform grease supply maintenance without removing the clutch housing 30 (or the manual transmission unit including the clutch housing 30) from the vehicle. This grease supply device 100 uses a grease supply pipe 130 (in... Figure 2 (As shown in the figure) Grease is supplied from the outside of the clutch housing 30 to the contact portion between the clutch release fork 21 and the release bearing 15, which is the part requiring grease supply, through the through hole 31 of the clutch housing 30.

[0072] like Figure 2 As shown, the grease supply device 100 is configured to include a first clamp 110, a second clamp 120, a grease supply pipe 130, a flexible pipe 140, and a grease dispenser 150. The first clamp 110 and the second clamp 120 are components used to position the grease supply pipe 130. The first clamp 110 is a component fitted into the through hole 31 of the clutch housing 30. The second clamp 120 is a component inserted into the insertion hole of the first clamp 110.

[0073] The first clamp 110 is a guide clamp that restricts the direction (insertion direction) of the grease supply tube 130 (grease injection tube), and has a base 111, a protrusion 112, and a first hole 113 and a second hole 114 for positioning. The first clamp 110 is a one-piece molded metal product. The base 111 is formed into a flat plate shape, having a shape that partially covers the opening of the through hole 31. The width of the base 111 (the length in the Y direction described later) is greater than the opening width of the through hole 31. The protrusion 112 is the portion that protrudes from the base 111 and is inserted into the through hole 31. The protrusion 112 functions as a positioning portion, which positions the first clamp 110 by abutting against the inner surface 31a of the through hole 31 and against the plane 21d of the clutch release fork 21.

[0074] The first hole 113 and the second hole 114 are insertion holes for inserting the grease supply tube 130 and the insertion portion 121 of the second clamp 120, and positioning holes for positioning the grease supply tube 130. The first hole 113 and the second hole 114 are formed in a row along the width direction of the first clamp 110, and are both through holes extending from the base 111 on the base end side to the protrusion 112 on the top end side. It should be noted that, in this description, unless otherwise specified, the first hole 113 and the second hole 114 are referred to as "insertion holes".

[0075] The second clamp 120 has: a prism-shaped insertion portion 121, inserted into the first hole 113 and the second hole 114 of the first clamp 110; and a stop portion 122, abutting against the surface 111a of the first clamp 110. The second clamp 120 is a one-piece metal product. Furthermore, the grease supply tube 130 is integrally formed into the second clamp 120. The second clamp 120 has two through holes 123 and 124 extending linearly from the base end side to the top end side along the insertion portion 121. One through hole 123 is for the grease supply tube. The other through hole 124 is for the endoscope. The grease supply tube 130 is fixed in the state of being inserted through the through hole 123. The endoscope 160 is fixed in the state of being inserted through the through hole 124 (see reference). Figure 3 Furthermore, the stop portion 122 has a stop surface 122a that abuts against the surface 111a of the first clamp 110 (in Figure 3 (as shown in the image).

[0076] The grease supply pipe 130 is a pipe used to supply grease to the contact portion between the pressing part 21a of the clutch release fork 21 and the release bearing 15 inside the clutch housing 30. The grease supply pipe 130 is an elongated ejection portion including a tip portion 131 for ejecting grease (an example of the fluid of the present invention). The grease supply pipe 130 is made of metal. An opening 131a for ejecting grease is provided at the tip portion 131 of the grease supply pipe 130. A flexible tube 140 is connected to the base end side of the grease supply pipe 130. The grease supply pipe 130 is connected to the grease dispenser 150 via the flexible tube 140.

[0077] like Figure 3 As shown, the grease supply device 100 includes an endoscope 160 as an imaging unit. The endoscope 160 is an elongated imaging device with an imaging section in its tip portion 160a, which captures images of the tip portion 131 of the grease supply tube 130 and its surrounding structures (e.g., corresponding portion C). The endoscope 160 is an example of the imaging device of the present invention. The endoscope 160 is integrated into the second clamp 120 and protrudes from the tip side of the insertion portion 121. The tip side of the endoscope 160 is the portion inserted into the interior of the clutch housing 30, and a lens is provided in this tip portion 160a. The base side of the endoscope 160 is connected to the operation portion 162 via a cable 161. By operating the operation portion 162, imaging of the internal structure of the clutch housing 30 through the endoscope 160 can be achieved. Images captured by the endoscope 160 (e.g., images including the tip 131 of the fat supply tube 130 and its surrounding structures (e.g., the corresponding part C)) can be displayed on the display unit 163 mounted on the operation unit 162.

[0078] The grease supply unit 150 consists of a cylinder 151 and a push rod 152 (piston) (see reference). Figure 3The flexible tube 140 is connected to the cylinder 151 of the grease supply unit 150. By pushing the push rod 152 while the cylinder 151 is filled with grease, grease can be supplied from the grease supply unit 150 to the grease supply tube 130. For example, the grease supply tube 130 can be inserted into the clutch housing 30 through the through hole 31 while the grease supply tube 130 and the flexible tube 140 are pre-filled with grease, thereby smoothly performing grease supply achieved by operating the grease supply unit 150.

[0079] The tip 131 of the grease supply tube 130 has a reduced diameter shape and includes an opening 131a for injecting grease. For example, as... Figure 4A As shown, the opening 131a of the grease supply tube 130 can be a circular opening 131a. Or, as... Figure 4B As shown, the opening 131a can also be flat. The top end 131 of the grease supply pipe 130 has a narrowed diameter, thereby enabling grease supply to the parts requiring grease supply through the narrow space within the clutch housing 30.

[0080] Here, refer to Figure 5 , Figures 6A-6C The first fixture 110 is described in detail. Figure 5 This is a top view of the base end side of the first clamp 110. Figure 6A It means Figure 5 The diagram of the A-direction view. Figure 6B This is a perspective view of the first clamp 110 viewed from the back side. Figure 6C It means Figure 5 A diagram of the VIC-VIC line cross section.

[0081] like Figure 5 As shown, the first clamp 110 has a rectangular opening with a first hole 113 and a second hole 114 on the surface 111a side of the base 111. The inner surface of the first hole 113 functions as a guide surface for positioning the grease supply tube 130 by abutting against the insertion part 121, and has a first surface 113a, a second surface 113b, a third surface 113c, and a fourth surface 113d. The first surface 113a and the second surface 113b are opposite each other in the Y direction, forming the shorter side portion of the rectangle. The third surface 113c and the fourth surface 113d are opposite each other in the X direction, forming the longer side portion of the rectangle. The inner surface of the second hole 114 functions as a guide surface for positioning the grease supply tube 130, and has a first surface 114a, a second surface 114b, a third surface 114c, and a fourth surface 114d. The first face 114a and the second face 114b are opposite faces in the Y direction, forming the shorter side of a rectangle. The third face 114c and the fourth face 114d are opposite faces in the X direction, forming the longer side of a rectangle.

[0082] Furthermore, the first clamp 110 has an abutment surface 115 that abuts against the plane 21d of the clutch release fork 21. The abutment surface 115 is a positioning surface, and its position in the X direction can be determined by abutting against the plane 21d of the clutch release fork 21. Figure 6A As shown, the contact surface 115 has a predetermined width in the width direction (Y direction) of the base 111 and extends along the height direction (Z direction) of the protrusion 112.

[0083] like Figure 6B As shown, a key portion 116 is provided on the back side 111b of the first clamp 110. The key portion 116 is the part that hooks onto the clutch housing 30 when the protrusion 112 is inserted into the through hole 31. This key portion 116 functions as a part that holds the first clamp 110 within the through hole 31. Furthermore, the openings of the first hole 113 and the second hole 114 in the protrusion 112 are also rectangular in shape, similar to the base end side. Figure 6C As shown, the first hole 113 extends linearly inside the protrusion 112.

[0084] Next, refer to Figures 7-9 The method of grease supply implemented by the grease supply device 100 will be described. Figure 7 This diagram shows the state in which the first clamp 110 is assembled into the through hole 31 of the clutch housing 30. Figure 8 The diagram shows the state in which the grease supply pipe 130 extends toward the pressing part 21a of the clutch release fork 21 when the second clamp 120 is inserted into the insertion hole of the first clamp 110. Figure 9 This diagram illustrates the height position of the tip 131 of the grease supply tube 130. It should be noted that... Figure 9 The Z direction shown indicates the height direction. Before performing the following procedures, remove the fork sleeve 32. This opens the through hole 31 of the clutch housing 30 for inserting the grease supply pipe 130, etc. (see reference). Figure 2 , Figure 9 (etc.) are revealed.

[0085] As a first step, the first clamp 110 is fixed to the through hole 31 of the clutch housing 30 (an example of the fixing object of the present invention).

[0086] Figure 11 It means from Figure 9 Diagram of the first clamp 110 and the second clamp 120 that have been extracted.

[0087] like Figure 11 As shown, the first clamp 110 is fixed to the clutch housing 30 (the portion surrounding the through hole 31) in a state where it is positioned relative to the clutch housing 30 in the X, Y and Z directions.

[0088] Specifically, firstly, the protrusion 112 of the first clamp 110 is positioned opposite to the through hole 31 of the clutch housing 30 (see reference). Figure 2 And make the abutment surface 115 of the first clamp 110 and the clutch release fork 21 (plane 21d) face each other (in contact) (see reference). Figure 7 ).

[0089] Next, the first clamp 110 is moved along the clutch release fork 21 (plane 21d) towards the through hole 31 (refer to...). Figure 2 The arrow AR1 in the diagram slides and moves until the protrusion 112 of the first clamp 110 is inserted into the through hole 31 and the base 111 of the first clamp 110 abuts against the surrounding portion of the through hole 31 in the clutch housing 30.

[0090] The protrusion 112 of the first clamp 110 is inserted into the through hole 31. The sides 112a and 112b of the protrusion 112 are opposite (abut against) the inner surfaces 31a and 31b of the through hole 31, thereby positioning the first clamp 110 relative to the clutch housing 30 in the Y direction.

[0091] Furthermore, the base 111 of the first clamp 110 abuts against the periphery of the through hole 31 in the clutch housing 30, thereby positioning the first clamp 110 relative to the clutch housing 30 in the Z direction.

[0092] Next, the first clamp 110, positioned relative to the clutch housing 30 in the Y and Z directions as described above, is moved along the direction of arrow AR2 (refer to...). Figure 7 , Figure 11 Press in.

[0093] Specifically, the first clamp 110, positioned relative to the clutch housing 30 in the Y and Z directions as described above, is positioned along the direction of arrow AR2 (refer to...). Figure 7 , Figure 11 Press in until the portion surrounding the through hole 31 in the clutch housing 30 is inserted (pressed in) into the space between the base 111 and the key 116 of the first clamp 110 (see reference). Figure 11 The through hole 31 extends until the surrounding portion of the through hole 31 reaches the bottom 117 between the base 111 and the key portion 116 of the first clamp 110.

[0094] The distance A1 between the base 111 and the key 116 of the first clamp 110 (refer to...) Figure 11 The thickness B1 of the portion surrounding the through hole 31 in the clutch housing 30 (refer to) Figure 11The relationship is set as A1 < B1. Therefore, when the first clamp 110 is positioned relative to the clutch housing 30 in the Y and Z directions as described above, along the direction of arrow AR2 (refer to...), Figure 7 , Figure 11 When pressed in, the portion surrounding the through hole 31 in the clutch housing 30 is inserted (pressed in) into the space between the base 111 and the key 116 of the first clamp 110. Thus, the first clamp 110 is fixed to the clutch housing 30.

[0095] Furthermore, the periphery of the through hole 31 in the clutch housing 30 touches the bottom 117 between the base 111 and the key 116 of the first clamp 110, thereby positioning the first clamp 110 relative to the clutch housing 30 in the X direction.

[0096] As described above, the first clamp 110 is fixed to the clutch housing 30 (the portion surrounding the through hole 31) in a state where it is positioned relative to the clutch housing 30 (an example of the fixing object of the present invention) in the X, Y, and Z directions. In other words, the first clamp 110 engages with the portion surrounding the through hole 31 in the clutch housing 30 in a state where it is positioned relative to the clutch housing 30 in the X, Y, and Z directions. The base 111 and key 116 of the first clamp 110 are examples of the engaging portion of the present invention.

[0097] Thus, with the first clamp 110 fixed to the clutch housing 30 (the portion surrounding the through hole 31), the first hole 113 of the first clamp 110 extends toward the corresponding portion C (one of the pressing portions 21a) (see reference). Figure 9 Similarly, the second hole 114 of the first clamp 110 extends toward the corresponding part C (the pressing part 21a on the other side). It should be noted that the first clamp 110 can be removed from the clutch housing 30 by following the reverse order as described above.

[0098] The next step after the first step is the insertion process (insertion process) of inserting the grease supply pipe 130 and the second clamp 120 into the insertion holes (first hole 113, second hole 114) of the first clamp 110, which is fixed to the clutch housing 30 as described above. In this insertion process, the second clamp 120 is inserted into the insertion holes (first hole 113, second hole 114) of the first clamp 110 in two stages. On the sides 121a and 121b of the insertion portion 121 of the second clamp 120, marking lines, as described later in the second embodiment, are marked at a predetermined distance from the top end. The outer periphery of the insertion portion 121 is rectangular. The sides 121a and 121b are the shorter sides of the rectangle. Furthermore, side 121a is one face in the Y direction, and side 121b is the other face in the Y direction. Furthermore, the rectangle of the insertion part 121 is smaller than the rectangle of the opening of the first hole 113 and the rectangle of the opening of the second hole 114.

[0099] like Figure 8 As shown, the insertion portion 121 of the second clamp 120 is inserted into the first hole 113 of the first clamp 110, thereby extending the grease supply pipe 130 toward the pressing portion 21a of the clutch release fork 21, which is the part requiring grease supply. The pressing portion 21a has a two-pronged structure, so the grease supply pipe 130 inserted into the first hole 113 extends toward one of the pressing portions 21a. Sometimes it is necessary to avoid obstacles inside the clutch housing 30 until the grease supply pipe 130 reaches the vicinity of the pressing portion 21a of the clutch release fork 21. For example, a clip, which is a component of the release bearing 15, is an example of an obstacle. The clip is located near the two-pronged structure of the clutch release fork 21, so it is ideal that the grease supply pipe 130 does not encounter the clip before reaching the pressing portion 21a.

[0100] Therefore, as the second step (the first half of the insertion step), the insertion part 121 of the second clamp 120 is inserted into the insertion hole of the first clamp 110 until the marked line is reached. The second clamp 120 can be moved relative to the first clamp 110 within the insertion hole, so that in this second insertion state, the grease supply tube 130 and the endoscope 160 can avoid obstacles within the clutch housing 30. That is, as the third step, a step is performed to move the second clamp 120 in a way that avoids the internal structure of the clutch housing 30 (avoidance action step). In the following steps, the operator performs the following operation: while looking at the screen displayed on the display 163 of the operating part 162 held by one hand (e.g., the right hand) (including an image of the top part 131 of the grease supply tube 130 and its surrounding structures (e.g., the corresponding part C)), the second clamp 120 (insertion part 121) held by the other hand (e.g., the left hand) is moved towards the corresponding part C in the direction of arrow AR3 (see reference). Figure 9 , Figure 11 Insert the tube 130 so that the tip 131 of the grease supply tube 130 reaches the corresponding part C (refer to...). Figure 9 ).

[0101] Regarding the third step, when the insertion part 121 is inserted into the first hole 113, a gap (approximately 0.5 mm) is provided between the sides 121a and 121b of the insertion part 121 and the inner surface (inner wall) of the first hole 113. Similarly, when the insertion part 121 is inserted into the second hole 114, a gap (approximately 0.5 mm) is provided between the sides 121a and 121b of the insertion part 121 and the inner surface (inner wall) of the second hole 114. Therefore, as long as the second clamp 120 is inserted into the insertion hole up to the mark line, the grease supply tube 130 can be positioned at a height where it will not contact the clamping member of the release bearing 15 and avoid the clamping member and other internal structures. In this case, the stop part 122 side can be held by hand, and the top end side of the insertion part 121 can be moved by swinging in the Y direction.

[0102] like Figure 9 As shown, when the height of the tip 131 of the grease supply tube 130 is at height h1, it is positioned to avoid the clamping member of the release bearing 15. In this case, the insertion of the grease supply tube 130 is stopped, and the position of the tip 131 is controlled to avoid the clamping member of the release bearing 15. This height h1 also represents the insertion amount (stroke amount).

[0103] For example, in the third step, after the side 121b of the insertion part 121 contacts the first surface 113a of the first hole 113, as an action to avoid obstacles within the clutch housing 30, the side 121a of the insertion part 121 contacts the second surface 113b of the first hole 113, which is in a non-contact state. At this time, the second clamp 120 is moved until the insertion part 121 slides on the third surface 113c of the first hole 113, so that the side 121a contacts the second surface 113b. This sliding includes a parallel movement in the Y direction and a rocking motion that swings the tip 131 laterally left and right. Thus, the grease supply pipe 130 is in a position where it does not contact the clamp.

[0104] Thus, after the position of the grease supply pipe 130 is determined to avoid obstacles within the clutch housing 30, the tip 131 of the grease supply pipe 130 is again brought closer to the area requiring grease supply. That is, the insertion process of the second clamp 120 is restarted, and the insertion part 121 is inserted into the through hole 31 until the stop part 122 of the second clamp 120 abuts against the base 111 of the first clamp 110. With the stop part 122 of the second clamp 120 in contact with the first clamp 110, the tip 131 of the grease supply pipe 130 is inserted into the clutch housing 30 to the predetermined target position. In other words, as the fourth process (the second half of the insertion process), the insertion part 121 is inserted deeper than the marked line, and the tip 131 of the grease supply pipe 130 is inserted into the area requiring grease supply.

[0105] like Figure 9 As shown, in the fourth step, the tip 131 of the grease supply pipe 130 reaches a height h2 where the pressing part 21a of one of the two structures is located. Thus, the tip 131 of the grease supply pipe 130 can be positioned near the pressing part 21a of the clutch release fork 21. The insertion depth at height h2 is greater than the insertion depth at height h1.

[0106] Then, as the fifth step, the process of supplying grease from the opening 131a of the grease supply tube 130 is performed. In this fifth step, the operator, while looking at the screen displayed on the display unit 163 of the operation unit 162 which is held by one hand (e.g., the right hand) (including an image of the top end 131 of the grease supply tube 130 and its surrounding structures (e.g., the corresponding part C), operates the grease supply device 150 by holding it with the other hand (e.g., the left hand). Figure 3 The push rod 152 shown is pushed axially, thereby supplying grease from the opening 131a of the grease supply pipe 130 to the corresponding part C (see reference). Figure 9In the fifth step, when an appropriate amount of grease is supplied from the grease dispenser 150 connected to the grease supply tube 130, an appropriate amount of grease is ejected from the tip 131 of the grease supply tube 130 and applied to the pressing part 21a. In this case, the grease supply tube 130 is pre-filled with grease from the grease dispenser 150. Therefore, when the tip 131 of the grease supply tube 130 is positioned as desired, grease supply achieved by operating the grease dispenser 150 will proceed smoothly.

[0107] Then, when the grease supply in the fifth step is completed, the sixth step is to remove the grease supply tube 130. In the sixth step, while keeping the first clamp 110 fitted into the through hole 31, the grease at the tip 131 of the grease supply tube 130 is cut off. After that, the second clamp 120 is pulled out from the through hole 31, and the tip 131 of the grease supply tube 130 is also pulled out from the through hole 31 to the outside of the clutch housing 30.

[0108] For example, the second clamp 120 is pulled out from the insertion hole of the first clamp 110. When the second clamp 120 is pulled out from the insertion hole of the first clamp 110, the second clamp 120 can swing left and right through the gap between the insertion hole and the insertion part 121. As a result, grease can be prevented from adhering to parts and components other than the parts that need grease supply.

[0109] If the first to fifth steps described above are for the first hole 113, then the second to fifth steps, which target the second hole 114, are performed while maintaining the assembly state of the first fixture 110. This allows for grease supply to both sides of the pressing part 21a with its two-pronged structure.

[0110] It should be noted that if there are no obstructions inside the clutch housing 30 before reaching the point where grease needs to be supplied, the second and third steps described above can be omitted. In this case, the marking line on the second clamp 120 may not be required, and the fourth step can be performed after the first step, inserting the insertion part 121 of the second clamp 120 into the insertion hole of the first clamp 110, and continuing to insert until the stop part 122 abuts against the first clamp 110.

[0111] As explained above, according to the grease supply device 100 of the first embodiment, grease can be supplied to the pressing portion 21a of the clutch release fork 21 even without removing the clutch housing 30 (or the manual transmission unit including the clutch housing 30) from the vehicle. As a result, grease supply maintenance work becomes easier and workability is improved.

[0112] Next, the insertion amount control device 100A of the second embodiment will be described. Figures 12A-12C This is a schematic diagram of the insertion amount control device according to the second embodiment. Figures 12A-12C The following describes the situation where the first clamp 110 is inserted into the second clamp 120.

[0113] The insertion amount control device 100A is used to visually control the position P1 (see reference) near the corresponding part C from the top end 131 of the grease supply pipe 130 outside the clutch housing 30. Figure 9 ) or reach a position P2 that is closer to the specified distance than the corresponding part C (refer to Figure 9 The means for determining the required insertion amount (hereinafter also referred to as the required insertion amount) of the second clamp 120 relative to the first clamp 110 up to the first clamp 110.

[0114] The insertion amount control device 100A has the same configuration as the grease supply device 100 of the first embodiment, but the difference is that the insertion part 121 of the second clamp 120 is marked with a first marking line L1 and a second marking line L2.

[0115] Hereinafter, the description will focus on the differences from the first embodiment, and the same reference numerals will be used for the same components as in the first embodiment, and the description will be omitted as appropriate. In the following description, the first clamp 110 is provided as described in the first embodiment above, and is fixed to the clutch housing 30 (the portion around the through hole 31) in a state in which it is positioned relative to the clutch housing 30 in the X, Y and Z directions.

[0116] The first clamp 110 and the second clamp 120 can be made of either resin or metal.

[0117] like Figure 12A As shown, in the second clamp 120, the insertion part 121 is inserted into the first hole 113 (or the second hole 114) formed in the first clamp 110, and faces the corresponding part C (see reference) while being held by the operator. Figure 9 Insert the second clamp 120 in the direction of arrow AR4. As the second clamp 120 is inserted toward the corresponding part C, the tip 131 of the grease supply tube 130 soon reaches a position P2 closer to the corresponding part C than a predetermined distance away (see reference). Figure 9 The tip 131 of the grease supply tube 130 reaches position P1 near the corresponding part C (refer to...). Figure 9 ).

[0118] Thus, in order to visually determine that the tip 131 of the grease supply tube 130 has reached a position P2 closer to the corresponding part C by a predetermined distance (refer to...) Figure 9 ), the corresponding position P1 near part C (refer to) Figure 9 The required insertion amount of the second clamp 120 relative to the first clamp 110 up to the specified depth is as follows: Figure 12AAs shown, the insertion part 121 of the second clamp 120 is marked with a first marking line L1 and a second marking line L2. It should be noted that the insertion part 121 of the second clamp 120 may also be marked with lines drawn with a magic marker or sticker instead of marking lines L1 and L2.

[0119] The first marking line L1 is set at a position P2 (refer to) where the top end 131 of the grease supply tube 130 has reached a predetermined distance closer than the corresponding part C. Figure 9 In the case where the tip 131 of the grease supply tube 130 and the corresponding part C are in a predetermined positional relationship, the first marking line L1 reaches the position of the first clamp 110 (e.g., the guide flange F provided on the first clamp 110) (e.g., overlapping with the guide flange F) (refer to...). Figure 12B ).

[0120] Therefore, by visually confirming the positional relationship between the first marking line L1 and the first clamp 110 (e.g., the guide flange F provided on the first clamp 110) from outside the clutch housing 30, the operator can determine the position P2 (refer to) where the top end 131 of the grease supply pipe 130 is closer to the corresponding part C by a predetermined distance. Figure 9 The required insertion amount of the second clamp 120 relative to the first clamp 110 up to )

[0121] The second marker line L2 is located at position P1 near the corresponding part C at the top end 131 of the grease supply tube 130 (refer to...). Figure 9 In the case where the tip 131 of the grease supply tube 130 and the corresponding part C are in a predetermined positional relationship, the second marking line L2 reaches the position of the first clamp 110 (e.g., the guide flange F provided on the first clamp 110) (e.g., overlapping with the guide flange F) (refer to...). Figure 12C ).

[0122] Therefore, by visually confirming the positional relationship between the second mark line L2 and the first clamp 110 (e.g., the guide flange F provided on the first clamp 110) from the outside of the clutch housing 30, the operator can determine the position P1 (refer to) where the top end 131 of the grease supply pipe 130 reaches the vicinity of the corresponding part C. Figure 9 The required insertion amount of the second clamp 120 relative to the first clamp 110 up to 110. It should be noted that the marking line L1 can also be omitted.

[0123] As explained above, according to the second embodiment, the position P1 (see reference) of the tip 131 of the grease supply pipe 130 reaching the vicinity of the corresponding part C can be visually determined from outside the clutch housing 30. Figure 9 ) or reach a position P2 that is closer to the specified distance than the corresponding part C (refer to Figure 9The required insertion amount of the second clamp 120 relative to the first clamp 110 up to )

[0124] Furthermore, according to the second embodiment, there are the following advantages. Specifically, the required insertion amount (stroke) until the tip 131 of the grease supply pipe 130 reaches the vicinity of the corresponding part C varies for each vehicle model (each manual transmission unit). In this case, for each vehicle model (each manual transmission unit) with different required insertion amounts, a mark (e.g., a line drawn with a marking line, Velcro, or sticker) indicating the arrival at the first clamp 110 (e.g., a guide flange F provided on the first clamp 110) is pre-marked on the insertion portion 121 of the second clamp 120, indicating the arrival at the first clamp 110. Thus, a single first clamp 110 can be used to supply grease to multiple vehicle models (multiple manual transmission units) with different required insertion amounts. That is, it is not necessary to prepare a first clamp 110 for each vehicle model (each manual transmission unit), thereby suppressing the increase in the types of first clamps 110 and the associated increase in investment (cost).

[0125] Next, the insertion amount control device 100B of the third embodiment will be described. Figures 13A-13B This is a schematic diagram of the insertion amount control device according to the third embodiment. Figures 13A-13B The following describes the situation where the first clamp 110 is inserted into the second clamp 120.

[0126] The insertion amount control device 100B is used to determine, without visual inspection, by touch (the feeling of the hand holding the second clamp 120) whether the tip 131 of the grease supply tube 130 has reached the position P1 near the corresponding part C (see reference). Figure 9 (The top part 131 of the grease supply tube 130 and the corresponding part C are in a predetermined positional relationship.)

[0127] The insertion amount control device 100B has the same configuration as the grease supply device 100 of the first embodiment, but the difference is that the insertion portion 121 of the second clamp 120 is provided with first protrusions p1a and p1b.

[0128] Hereinafter, the description will focus on the differences from the first embodiment, and the same reference numerals will be used for the same components as in the first embodiment, and the description will be omitted as appropriate. In the following description, the first clamp 110 is provided as described in the first embodiment above, and is fixed to the clutch housing 30 (the portion around the through hole 31) in a state in which it is positioned relative to the clutch housing 30 in the X, Y and Z directions.

[0129] At least one of the first clamp 110 and the second clamp 120 is made of resin. If one is made of resin, the other can be made of either resin or metal.

[0130] like Figure 13A As shown, in the second clamp 120, the insertion part 121 is inserted into the first hole 113 (or the second hole 114) formed in the first clamp 110, and faces the corresponding part C (see reference) while being held by the operator. Figure 9 Insert the second clamp 120 in the direction of arrow AR5. As the second clamp 120 is inserted toward the corresponding part C, the tip 131 of the grease supply tube 130 soon reaches position P1 near the corresponding part C (see reference). Figure 9 ).

[0131] Thus, in order to determine, without visual inspection, by touch (the feeling of the hand holding the second clamp 120), that the tip 131 of the grease supply tube 130 has reached the position P1 near the corresponding part C (see reference). Figure 9 (The top end 131 of the grease supply tube 130 and the corresponding part C are in a predetermined positional relationship), and the insertion part 121 of the second clamp 120 is provided with first protrusions p1a and p1b.

[0132] The first protrusions p1a and p1b are, for example, hemispherical protrusions. It should be noted that the first protrusions p1a and p1b are not limited to hemispherical shapes, but can also be protrusions of other shapes.

[0133] The first protrusions p1a and p1b are provided at position P1 (see reference) when the tip 131 of the grease supply tube 130 reaches the vicinity of the corresponding part C during the operation of inserting the second clamp 120 toward the corresponding part C. Figure 9 In the case of ), the first protrusions p1a and p1b are inserted into the first hole 113 (or the second hole 114) (see reference). Figure 13B And the location where friction (friction force) is generated between the first hole 113 (or the second hole 114).

[0134] To generate this friction, such as Figure 13A As shown, the diameter A2 (design size) of the first hole 113 (and the second hole 114) and the thickness B2 (design size) of the insertion portion 121 of the second clamp 120 including the first protrusions p1a and p1b are set to a relationship of A2 < B2.

[0135] Therefore, the operator can determine the position of the grease supply tube 130 by touch (the feeling of the hand holding the second clamp 120) without visual inspection, as the second clamp 120 is inserted toward the corresponding part C. Figure 9 (The aforementioned friction).

[0136] As explained above, according to the third embodiment, it is possible to determine, without visual inspection, by touch (the feeling of the hand holding the second clamp 120) whether the tip 131 of the grease supply tube 130 has reached the position P1 near the corresponding part C (see reference). Figure 9 (The top part 131 of the grease supply tube 130 and the corresponding part C are in a prescribed positional relationship.)

[0137] This is because the first protrusions p1a and p1b are present, and as the second clamp 120 is inserted toward the corresponding part C, the tip 131 of the grease supply tube 130 reaches a position P1 near the corresponding part C (see reference). Figure 9 In the case where the tip 131 of the grease supply tube 130 and the corresponding part C are in a predetermined positional relationship, it is inserted into the first hole 113 (or the second hole 114) (see reference). Figure 13B And friction (frictional force) is generated between it and the first hole 113 (or the second hole 114).

[0138] Therefore, the operator can focus on the following operation: while looking at the screen displayed on the display unit 163 of the operating unit 162 held by one hand (e.g., the right hand) (including images of the tip 131 of the grease supply tube 130 and its surrounding structures (e.g., the corresponding part C)), the operator inserts the second clamp 120 (insertion part 121) held by the other hand (e.g., the left hand) toward the corresponding part C in the direction of arrow AR5, so that the tip 131 of the grease supply tube 130 reaches a position P1 near the corresponding part C (see reference). Figure 9 ).

[0139] Furthermore, according to the third embodiment, there are the following advantages. That is, as described above, when the first protrusions p1a and p1b are inserted into the first hole 113 (or the second hole 114), the friction generated between the first protrusions p1a and p1b and the inner wall of the first hole 113 (or the second hole 114) causes the second clamp 120 to be fixed to the first clamp 110. Furthermore, the gap (void) between the insertion portion 121 of the second clamp 120 inserted into the first hole 113 (or the second hole 114) and the inner wall of the first hole 113 (or the second hole 114) is approximately 0.5 mm.

[0140] Therefore, even if the operator releases the hand holding the second clamp 120 when the aforementioned friction occurs, the position of the top part 131 of the grease supply tube 130 relative to the corresponding part C will not change (almost not change)

[0141] Therefore, under the aforementioned friction condition, that is, when the tip 131 of the grease supply tube 130 has reached the position P1 near the corresponding part C (refer to...), Figure 9In this case, release the other hand (e.g., the left hand) that was previously holding the second clamp 120, and use the free hand (e.g., the left hand) to hold the fat dispenser 150 again and operate it (e.g., to...). Figure 3 The push rod 152 shown is pushed axially, thereby supplying grease from the opening 131a of the grease supply pipe 130 to the corresponding part C. That is, one operator can perform the operation of inserting the second clamp 120 toward the corresponding part C, and then supplying grease from the opening 131a of the grease supply pipe 130 to the corresponding part C. As a result, work efficiency is improved.

[0142] Next, the insertion amount control device 100C of the fourth embodiment will be described. Figures 14A to 14C This is a schematic diagram of the insertion amount control device according to the fourth embodiment. Figures 14A to 14C The following describes the situation where the first clamp 110 is inserted into the second clamp 120.

[0143] The insertion depth control device 100C is used to control the position P2 (see reference) of the tip 131 of the grease supply tube 130 to be closer to a predetermined distance than the corresponding part C, without visual inspection, but by touch (the feeling of the hand holding the second clamp 120). Figure 9 ) or the tip 131 of the grease supply tube 130 has reached the position P1 near the corresponding part C (refer to Figure 9 (The top part 131 of the grease supply tube 130 and the corresponding part C are in a predetermined positional relationship.)

[0144] The insertion amount control device 100C has the same configuration as the grease supply device 100 of the first embodiment, but the difference from the grease supply device 100 of the first embodiment is that the insertion portion 121 of the second clamp 120 is provided with first protrusions p1a and p1b, and second protrusions p2a (p2a1, p2a2, p2a3) and p2b (p2b1, p2b2, p2b3) are provided on the inner wall of the first hole 113 (and the second hole 114) formed in the first clamp 110.

[0145] Hereinafter, the description will focus on the differences from the first embodiment, and the same reference numerals will be used for the same components as in the first embodiment, and the description will be omitted as appropriate. In the following description, the first clamp 110 is provided as described in the first embodiment above, and is fixed to the clutch housing 30 (the portion around the through hole 31) in a state in which it is positioned relative to the clutch housing 30 in the X, Y and Z directions.

[0146] At least one of the first clamp 110 and the second clamp 120 is made of resin. If one is made of resin, the other can be made of either resin or metal.

[0147] like Figure 14A As shown, in the second clamp 120, the insertion part 121 is inserted into the first hole 113 (or the second hole 114) formed in the first clamp 110, and faces the corresponding part C (see reference) while being held by the operator. Figure 9 Insert the second clamp 120 in the direction of arrow AR6. As the second clamp 120 is inserted toward the corresponding part C, the tip 131 of the grease supply tube 130 soon reaches a position P2 closer to the corresponding part C than a predetermined distance (see reference). Figure 9 The tip 131 of the grease supply tube 130 reaches position P1 near the corresponding part C (refer to...). Figure 9 ).

[0148] Thus, in order to determine, without visual inspection, by touch (the feeling of the hand holding the second clamp 120), that the tip 131 of the grease supply tube 130 has reached a position P2 closer to the corresponding part C than a predetermined distance (see reference). Figure 9 The tip 131 of the grease supply tube 130 has reached position P1 near the corresponding part C (refer to...). Figure 9 (The top end 131 of the grease supply tube 130 and the corresponding part C are in a predetermined positional relationship.) The insertion part 121 of the second clamp 120 is provided with first protrusions p1a and p1b. In addition, second protrusions p2a (p2a1, p2a2, p2a3) and p2b (p2b1, p2b2, p2b3) are provided on the inner wall of the first hole 113 (and the second hole 114) formed in the first clamp 110.

[0149] The first protrusions p1a and p1b, and the second protrusions p2a (p2a1, p2a2, p2a3) and p2b (p2b1, p2b2, p2b3) are, for example, hemispherical protrusions. It should be noted that the first protrusions p1a and p1b, and the second protrusions p2a (p2a1, p2a2, p2a3) and p2b (p2b1, p2b2, p2b3) are not limited to hemispherical shapes, but can also be protrusions of other shapes.

[0150] The first protrusions p1a and p1b are provided at a position P2 (see reference) where, during the operation of inserting the second clamp 120 toward the corresponding part C, the tip 131 of the grease supply tube 130 has reached a position P2 closer to the corresponding part C than a predetermined distance away. Figure 9 ) or the tip 131 of the grease supply tube 130 has reached the position P1 near the corresponding part C (refer to Figure 9 In the case where the first protrusions p1a and p1b are inserted into the position of the first hole 113 (or the second hole 114) (refer to...) Figure 14B , Figure 14C ).

[0151] The second protrusions p2a (p2a1, p2a2, p2a3) and p2b (p2b1, p2b2, p2b3) are arranged in a row along the insertion direction of the second clamp 120 (refer to arrow AR6 in Figure 14).

[0152] Regarding the first protrusions p1a and p1b, as the second clamp 120 is inserted toward the corresponding part C, friction is generated between them and each of the second protrusions p2a (p2a1, p2a2, p2a3) and p2b (p2b1, p2b2, p2b3), and friction is generated through each of the second protrusions p2a (p2a1, p2a2, p2a3) and p2b (p2b1, p2b2, p2b3).

[0153] To generate this friction, such as Figure 14A As shown, the diameter A3 (design dimension) of the first hole 113 (and the second hole 114) including the second protrusions p2a (p2a1, p2a2, p2a3) and p2b (p2b1, p2b2, p2b3) and the thickness B3 (design dimension) of the insertion portion 121 of the second clamp 120 including the first protrusions p1a and p1b are set to be A3 < B3.

[0154] Therefore, the operator can determine, without visual inspection, by touch (the feeling of the hand holding the second clamp 120) that as the second clamp 120 is inserted toward the corresponding part C, the tip 131 of the grease supply tube 130 has reached a position P2 closer to the corresponding part C than a predetermined distance (see reference). Figure 9 The tip 131 of the grease supply tube 130 has reached position P1 near the corresponding part C (refer to...). Figure 9 (The aforementioned friction). For example, during the operation of inserting the second clamp 120 toward the corresponding part C, when the first protrusions p1a and p1b abut (or press) against (or pass through) the second protrusions p2a1 and p2b1, the operator can, without visual inspection, determine by touch (the feeling of the hand holding the second clamp 120) that the tip 131 of the grease supply tube 130 has reached a position P2 closer to the corresponding part C than a predetermined distance (see reference). Figure 9 (The aforementioned friction). Furthermore, during the operation of further inserting the second clamp 120 toward the corresponding part C, when the first protrusions p1a and p1b abut (or press) against (or press against) the second protrusions p2a2 and p2b2 and have passed through the second protrusions p2a2 and p2b2, the operator can, without visual inspection, determine by touch (the feeling of the hand holding the second clamp 120) that the tip 131 of the grease supply tube 130 has reached the position P1 near the corresponding part C (see reference). Figure 9 (The aforementioned friction).

[0155] As explained above, according to the fourth embodiment, it is possible to determine, without visual inspection, by touch (the feeling of the hand holding the second clamp 120) whether the tip 131 of the grease supply tube 130 has reached a position P2 closer to the corresponding part C by a predetermined distance (see reference). Figure 9 ) or the tip 131 of the grease supply tube 130 has reached the position P1 near the corresponding part C (refer to Figure 9 (The top part 131 of the grease supply tube 130 and the corresponding part C are in a prescribed positional relationship.)

[0156] This is because the first protrusions p1a, p1b and the second protrusions p2a (p2a1, p2a2, p2a3) and p2b (p2b1, p2b2, p2b3) have, during the operation of inserting the second clamp 120 toward the corresponding part C, the tip 131 of the grease supply tube 130 has reached a position P2 (refer to) that is closer to the corresponding part C by a predetermined distance. Figure 9 The tip 131 of the grease supply tube 130 has reached position P1 near the corresponding part C (refer to...). Figure 9 In the case where the top part 131 of the grease supply tube 130 and the corresponding part C are in a predetermined positional relationship, friction (frictional force) is generated.

[0157] Therefore, the operator can focus on the following operation: while looking at the screen displayed on the display unit 163 of the operating unit 162 held by one hand (e.g., the right hand) (including images of the tip 131 of the grease supply tube 130 and its surrounding structures (e.g., the corresponding part C)), the operator inserts the second clamp 120 (insertion part 121) held by the other hand (e.g., the left hand) toward the corresponding part C in the direction of arrow AR6, so that the tip 131 of the grease supply tube 130 reaches a position P2 closer to the corresponding part C by a predetermined distance (see reference). Figure 9 The tip 131 of the grease supply tube 130 reaches position P1 near the corresponding part C (refer to...). Figure 9 ).

[0158] Furthermore, according to the fourth embodiment, there are the following advantages. That is, as described above, at position P1 (refer to) near the corresponding portion C at the tip 131 of the grease supply tube 130. Figure 9 And when the first protrusions p1a and p1b are inserted into the first hole 113 (or the second hole 114) (see reference). Figure 14C The second clamp 120 is fixed to the first clamp 110. Furthermore, the gap (void) between the insertion part 121 of the second clamp 120 inserted into the first hole 113 (or the second hole 114) and the inner wall of the first hole 113 (or the second hole 114) is about 0.5 mm.

[0159] Therefore, at position P1 near the corresponding part C at the tip 131 of the grease supply tube 130 (refer to...) Figure 9 And when the first protrusions p1a and p1b are inserted into the first hole 113 (or the second hole 114) (see reference). Figure 14C Even if the operator releases the hand holding the second clamp 120, the position of the top part 131 of the grease supply tube 130 relative to the corresponding part C will not change (almost not change).

[0160] Therefore, the tip 131 of the grease supply tube 130 has reached position P1 near the corresponding part C (refer to...). Figure 9 In this case, release the other hand (e.g., the left hand) that was previously holding the second clamp 120, and use the free hand (e.g., the left hand) to hold the fat dispenser 150 again and operate it (e.g., to...). Figure 3 The push rod 152 shown is pushed axially, thereby supplying grease from the opening 131a of the grease supply pipe 130 to the corresponding part C. That is, one operator can perform the operation of inserting the second clamp 120 toward the corresponding part C, and then supplying grease from the opening 131a of the grease supply pipe 130 to the corresponding part C. As a result, work efficiency is improved.

[0161] Furthermore, according to the fourth embodiment, there are the following advantages. Specifically, the required insertion amount (stroke) of the tip 131 of the grease supply pipe 130 until it reaches the vicinity of the corresponding part C varies for each vehicle model (each manual transmission unit). In this case, for each vehicle model (each manual transmission unit) with different required insertion amounts, second protrusions p2a (p2a1, p2a2, p2a3) and p2b (p2b1, p2b2, p2b3) are pre-configured to generate friction (frictional force) when the tip 131 of the grease supply pipe 130 has reached the vicinity of the corresponding part C. Therefore, a single first clamp 110 can be used to supply grease to multiple vehicle models (multiple manual transmission units) with different required insertion amounts. That is, it is not necessary to prepare a first clamp 110 for each vehicle model (each manual transmission unit), thus suppressing the increase in the number of types of first clamps 110 and the resulting increase in investment (cost).

[0162] Next, the variations will be explained.

[0163] Figure 15 This is a schematic diagram of the insertion amount control device (modified example) according to the fourth embodiment.

[0164] In the fourth embodiment, for example... Figure 14AAs shown, an example is given in which first protrusions p1a and p1b are provided in the insertion portion 121 of the second clamp 120, and second protrusions p2a (p2a1, p2a2, p2a3) and p2b (p2b1, p2b2, p2b3) are provided on the inner wall of the first hole 113 (and the second hole 114) formed in the first clamp 110. However, this is not the only example.

[0165] For example, it can also be like Figure 15 As shown, conversely, second protrusions p2a (p2a1, p2a2, p2a3) and p2b (p2b1, p2b2, p2b3) are provided in the insertion part 121 of the second clamp 120, and first protrusions p1a and p1b are provided on the inner wall of the first hole 113 (and the second hole 114) formed in the first clamp 110.

[0166] Furthermore, in the fourth embodiment, an example using three second protrusions p2a (p2a1, p2a2, p2a3) and p2b (p2b1, p2b2, p2b3) on one side was described, but it is not limited to this. For example, four or more second protrusions p2a and p2b on one side may also be used.

[0167] Next, as a fifth embodiment, the guide clamp 110A will be described. Figure 16 This is a side view of the guide clamp 110A with the second clamp 120 inserted. Figure 17 It means from Figure 16 A diagram of the extracted guide clamp 110A.

[0168] The guide clamp 110A has the same configuration as the first clamp 110 of the first embodiment described above, but the difference is that it has a locking portion 200 that engages with a plurality of locking objects of different thicknesses.

[0169] The following description focuses on the differences from the first clamp 110. For components that are the same as those in the first clamp 110, the same reference numerals are used and the descriptions are omitted as appropriate.

[0170] At least one of the guide clamp 110A and the second clamp 120 is made of resin. If one is made of resin, the other can be made of either resin or metal.

[0171] Figures 18A-18C This diagram illustrates a situation where the guide clamp 110A engages with multiple objects of different thicknesses.

[0172] The following describes multiple engaging objects of varying thicknesses, including the clutch housing 30A (the portion surrounding the through hole 31A) of thickness D. (See reference...) Figure 18AThe clutch housing 30B of thickness E (the portion surrounding the through hole 31B). (See reference...) Figure 18B The clutch housing 30C (surrounding the through hole 31C) with a thickness F. (See reference...) Figure 18C Let's take the case of F > D > E as an example to illustrate.

[0173] Guide clamp 110A is a guide clamp that restricts the direction (insertion direction) of the grease supply tube 130 (grease injection tube), such as... Figure 17 As shown, it includes: a guide clamp body 112 (the protrusion 112 in the first embodiment); and an engaging portion 200, provided on the guide clamp body 112, which engages with the engaging object when the guide clamp body 112 is positioned relative to the engaging object. In the fifth embodiment, three engaging portions 200A, 200B, and 200C are provided corresponding to three engaging objects with different thicknesses (clutch housing 30A with thickness D, clutch housing 30B with thickness E, and clutch housing 30C with thickness F).

[0174] The guide fixture body 112 has guide through holes (first hole 113, second hole 114), which are formed when the engaging parts 200 (engaging parts 200A, 200B, 200C) are engaged with the engaging object (see reference). Figures 18A-18C Oriented toward the corresponding part C (refer to) Figure 9 The through hole extends, and the insertion direction of the second clamp 120 (an example of the insertion part of the present invention) inserted into the through hole and inserted toward the corresponding part C in the direction of arrow AR7 is guided (see reference). Figure 17 ).

[0175] The engaging portion 200 includes three protrusions 201, 202, and 203. Protrusion 201 is part of the base 111 in the first embodiment. Protrusion 203 is the key portion 116 in the first embodiment.

[0176] The three protrusions 201, 202, and 203 are respectively located in the Y direction ( Figure 17 The plate-shaped portions extending in the direction perpendicular to the paper are arranged in a row facing the insertion direction AR7.

[0177] The intervals G1 and G2 between adjacent protrusions in the three protrusions 201, 202, and 203 are set to different lengths D and E (D > E).

[0178] Specifically, such as Figure 17 As shown, the spacing G1 between the adjacent protrusions 201 and 202 of the three protrusions 201, 202, and 203 is set to be the portion surrounding the clutch housing 30A (through hole 31A), which is the first engagement object. (Refer to...) Figure 18A The length D corresponding to the thickness of the protrusions 201 and 202, and the portion 117a (bottom) of the guide clamp body 112 between the protrusions 201 and 202 constitute the first engaging portion 200A.

[0179] like Figure 18A As shown, the edge of the clutch housing 30A (the portion surrounding the through hole 31A) of thickness D, which is inserted into the space G1 and is the object of engagement, encounters the portion 117a between the protrusions 201 and 202, or the protrusion 201 abuts against the clutch housing 30A (the portion surrounding the through hole 31A) of thickness D, which is inserted into the space G1 and is the object of engagement. (Refer to...) Figure 18A With one main surface of the clutch housing 30A engaged and the protrusion 202 abutting against the other main surface, the first engaging portion 200A engages with the clutch housing 30A (the portion surrounding the through hole 31A) of thickness D, which is the object of engagement. Thus, the guide clamp 110A is engaged (fixed) while positioned within the clutch housing 30A (the portion surrounding the through hole 31A) of thickness D, which is the object of engagement.

[0180] On the other hand, such as Figure 17 As shown, the spacing G2 between the adjacent protrusions 202 and 203 of the three protrusions 201, 202, and 203 is set to be the portion surrounding the clutch housing 30B (through hole 31B), which is the second engagement object. (Refer to...) Figure 18B The length E corresponding to the thickness of the protrusions 202 and 203, and part 117b (bottom) of the guide clamp body 112 between the protrusions 202 and 203 constitute the second engaging part 200B.

[0181] like Figure 18B As shown, the edge of the clutch housing 30B (the portion surrounding the through hole 31B) of thickness E, which is inserted into the space G2 and is the object of engagement, encounters the portion 117b between the protrusions 202 and 203, or the protrusion 202 abuts against the clutch housing 30B (the portion surrounding the through hole 31B) of thickness E, which is inserted into the space G2 and is the object of engagement. (Refer to...) Figure 18B With one main surface of the clutch housing 30B engaged and the protrusion 203 abutting against the other main surface, the second engaging portion 200B engages with the clutch housing 30B (the portion surrounding the through hole 31B) of thickness E, which is the object of engagement. Thus, the guide clamp 110A is engaged (fixed) while positioned within the clutch housing 30B (the portion surrounding the through hole 31B) of thickness E, which is the object of engagement.

[0182] In addition, such as Figure 17As shown, the interval G3 between the protrusions 201 and 203 located at both ends in the insertion direction AR7 of the three protrusions 201, 202, and 203 is set to be the portion surrounding the clutch housing 30C (through hole 31C), which is the third engagement object. (Refer to...) Figure 18C The length F corresponding to the thickness of the part. The protrusions 201, 203 and the top part 202a of the protrusion 202 constitute the third engaging part 200C.

[0183] like Figure 18C As shown, the edge of the clutch housing 30C (the portion surrounding the through hole 31C) of thickness F, which is inserted into the space G3 and is the object of engagement, comes into contact with the portion between the protrusion 201 and the protrusion 203 (the top end 202a of the protrusion 202), or the protrusion 201 abuts against the clutch housing 30C (the portion surrounding the through hole 31C) of thickness F, which is inserted into the space G3 and is the object of engagement. (Refer to...) Figure 18C With one main surface of the clutch housing 30C engaged and the protrusion 203 abutting against the other main surface, the third engaging portion 200C engages with the clutch housing 30C (the portion surrounding the through hole 31C) of thickness F, which is the object of engagement. Thus, the guide clamp 110A is engaged (fixed) while positioned within the clutch housing 30C (the portion surrounding the through hole 31C) of thickness F, which is the object of engagement.

[0184] As described above, according to the fifth embodiment, a guide clamp 110A can be provided that is engaged (fixed) in a state where it is positioned on an engaging object (a plurality of engaging objects of different thicknesses).

[0185] Next, as a sixth embodiment, the guide clamp 110B will be described. Figure 19 This is a side view of the guide clamp 110B into which the second clamp 120 is inserted. Figure 20 It means from Figure 19 A diagram of the extracted guide clamp 110B.

[0186] The guide clamp 110B has the same configuration as the first clamp 110 of the first embodiment described above, but the difference is that it has a locking portion 300 that engages with a plurality of locking objects of different thicknesses.

[0187] The following description focuses on the differences from the first clamp 110. For components that are the same as those in the first clamp 110, the same reference numerals are used and the descriptions are omitted as appropriate.

[0188] At least one of the guide clamp 110B and the second clamp 120 is made of resin. If one is made of resin, the other can be made of either resin or metal. It should be noted that ideally, the guide clamp 110B is made of a material with appropriate rigidity, sufficient margin, and sufficient friction.

[0189] Guide clamp 110B is a guide clamp that restricts the direction (insertion direction) of the grease supply tube 130 (grease injection tube), such as... Figure 20 As shown, it includes: a guide clamp body 112 (the protrusion 112 in the first embodiment); and a locking part 300, which is provided on the guide clamp body 112 and locks onto the locking object when the guide clamp body 112 is positioned relative to the locking object.

[0190] The guide fixture body 112 has guide through holes (first hole 113, second hole 114), which face the corresponding part C (see reference) when the engaging part 300 is engaged with the engaging object. Figure 9 The through hole extends and guides the insertion direction of the second clamp 120 (an example of the insertion part of the present invention) inserted into the through hole and inserted toward the corresponding part C in the direction of arrow AR8.

[0191] The engaging portion 300 includes two protrusions 301 and 302. Protrusion 301 is part of the base 111 in the first embodiment. Protrusion 302 is the key portion 116 in the first embodiment.

[0192] The two protrusions 301 and 302 are respectively in the Y direction ( Figure 20 The plate-shaped portions extending in the direction perpendicular to the paper are arranged in a row facing the insertion direction AR8.

[0193] The spacing between the two protrusions 301 and 302 widens towards the tips of the protrusions 301 and 302. Specifically, one of the protrusions 301 and 302 is inclined at an angle θ relative to the other protrusion 302 (see reference). Figure 20 The protrusions 301 and 302, and part 117 (bottom) of the guide clamp body 112 between the protrusions 301 and 302 constitute the engaging part 300.

[0194] A slotting process (processed into multiple minute undulations or concave-convex shapes) is performed on one of the protrusions 302 to allow at least a portion of the engaging object inserted into the gap between the protrusions 301 and 302 to abut. It should be noted that a slotting process (multiple minute undulations or concave-convex shapes) can also be performed on the other protrusion 301.

[0195] Figure 21A This is an example of grooving in the shape of a rectangular wave. Figure 21B This is an example of a grooving process with a sawtooth wave shape.

[0196] In addition, such as Figure 19 As shown, the guide clamp 110B, into which the second clamp 120 is inserted, is used to set the weight balance by rotating clockwise (refer to arrow AR9) around the center of gravity CP of the guide clamp 110B using its own weight.

[0197] Next, an example of the action of engaging the guide clamp 110B with the engaging object will be described.

[0198] Figures 22A to 22C This is a diagram illustrating an example of the action of engaging the guide clamp 110B with an engaging object.

[0199] First, such as Figure 22A As shown, the gap between the protrusions 301 and 302 is positioned opposite to the edge of the clutch housing 30 (the portion surrounding the through hole 31) which is the object of engagement.

[0200] Next, guide the clamp 110B along the direction of arrow AR2 (refer to...). Figure 22A Press in.

[0201] Specifically, the guide clamp 110B is held, such as... Figure 22B As shown, guide the clamp 110B along the direction of arrow AR2 (refer to...). Figure 22A Press in until the periphery of the through hole 31 in the clutch housing 30 is inserted into the gap between the protrusions 301 and 302 of the guide clamp 110B, and the periphery of the through hole 31 touches the bottom 117 between the protrusions 301 and 302 of the guide clamp 110B. At this time, the slotting process performed on the protrusion 302 is a sawtooth wave shape (see reference). Figure 21B In this case, the slope is gentle, so the hook resistance is small and it is easy to assemble (lock).

[0202] Next, release your hand from the guide clamp 110B. Then, as... Figure 22C As shown, the guide clamp 110B rotates clockwise (refer to arrow direction AR9) around its center of gravity CP using its own weight, and engages with the clutch housing 30 (the portion surrounding the through hole 31) at three locations Po1, Po2, and Po3. This ensures the required vertical reaction force (refer to...) Figure 23A The attached figure's reference numeral N' or Figure 23B The attached diagram (N) and friction force can suppress loosening in response to external forces such as vibration during operation, thus maintaining the stable posture of the guide clamp 110B.

[0203] Figure 23A This is a diagram using vectors to represent the force applied to the contact portion Po3 between the protrusion 302 and the clutch housing 30 (the portion surrounding the through hole 31) when the slotting of the protrusion 302 is processed into a rectangular wave shape. Figure 23B This is a diagram, using vectors, representing the force applied to the contact portion Po3 between the protrusion 302 and the clutch housing 30 (the portion surrounding the through hole 31) when the groove machining of the protrusion 302 is performed into a sawtooth wave shape. (Refer to...) Figure 23A and Figure 23B In the case where the slotting process is carried out into a rectangular wave shape (refer to...) Figure 23A Under the condition that the grooving is processed into a sawtooth wave shape (refer to...) Figure 23B Compared to the previous method, the required vertical resistance is greater (N' > N), thus allowing the guide clamp 110B to engage more securely with the object being engaged.

[0204] Furthermore, the spacing between the two protrusions 301 and 302 widens towards the tips of the protrusions 301 and 302, that is, one of the protrusions 301 is tilted at an angle θ relative to the other protrusion 302 (see reference). Figure 20 Therefore, the guide clamp 110B can engage with multiple engaging objects of different thicknesses.

[0205] As described above, according to the sixth embodiment, a guide clamp 110B can be provided that is engaged (fixed) in a state where it is positioned on an engaging object (a plurality of engaging objects of different thicknesses).

[0206] Next, variations of the first to sixth embodiments described above will be explained.

[0207] In the first to sixth embodiments described above, examples of using grease as a fluid were given, but the method is not limited to this. For example, a liquid may also be used as a fluid.
