Description

Technical Field

[0002] Gears are mechanical components with teeth on the rim that can continuously mesh to transmit motion and power. During the gear processing process, due to cutting, casting or forging processes, tiny burrs and unevenness may occur on the tooth surface, tooth top, tooth root and inner hole of the gear. These burrs and unevenness will not only affect the assembly accuracy and transmission accuracy of the gear, but may also cause problems such as increased noise, increased wear and shortened service life. Therefore, it is necessary to grind and polish the burrs on the gear to remove the burrs and improve the smoothness and flatness of the gear surface. When grinding and polishing the burrs on the gear, it is generally The gear is placed on a rotating mold, and then the gear is ground and polished by the grinding blocks on both sides.

DETAILED DESCRIPTION

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0034] Example 1

[0035] Reference Figure 1-Figure 12, which is the first embodiment of the present invention, and provides a grinding device for gear processing. The grinding device for gear processing includes a positioning assembly 200, including a rotating sleeve 201, an extrusion plate 201a, a rotating disk 201b, a movable rod 201c, a guide shaft 201d, a movable column 201e, a fixed shaft 201f and a force plate 201g. The extrusion plate 201a is located in the rotating sleeve 201, the rotating disk 201b is rotatably connected to the rotating sleeve 201, and one end of the movable rod 201c is connected to the extrusion plate 201a. Plate 201a is fixed, guide shaft 201d is fixed to the bottom of movable rod 201c, guide groove 201b-1 is opened on rotating disk 201b, guide shaft 201d slides in guide groove 201b-1, movable column 201e is inserted in rotating disk 201b, fixed shaft 201f is fixed in rotating disk 201b, spiral groove 201e-1 is opened on movable column 201e, fixed shaft 201f slides in spiral groove 201e-1, and one end of force plate 201g is fixed to movable column 201e.

[0036] There are four extrusion plates 201a, which are evenly distributed in a ring shape inside the rotating sleeve 201. The guide groove 201b-1 is arc-shaped, with one end close to the inner ring of the rotating disk 201b and the other end close to the outer ring of the rotating disk 201b. A through groove is opened on the rotating sleeve 201, and one end of the force-bearing plate 201g extends to the outside of the rotating sleeve 201 and is movably connected with the through groove.

[0037] When the gear is placed on the outside of the rotating sleeve 201, the weight of the gear will press the force plate 201g downward, and the force plate 201g will drive the movable column 201e to move downward. At this time, the fixed shaft 201f will slide in the spiral groove 201e-1, and the cooperation of the two will drive the rotating disk 201b to rotate. At this time, the guide shaft 201d will slide in the guide groove 201b-1, and the cooperation of the two will drive the movable rod 201c and the extrusion plate 201a to move, so that the extrusion plate 201a contacts the inner wall of the gear and squeezes the inner wall of the gear, so that the gear can be fixed, and then the gear can be driven to rotate through the rotating sleeve 201, and the gear can be ground and polished. When grinding and polishing gears of different specifications, there is no need to replace the rotating mold, and it can adapt to gears of different specifications, thereby improving production efficiency.

[0038] The tilting assembly 300 is connected to the positioning assembly 200, and includes a rotating shaft 301, a fixing column 301a, a supporting ball 301b, a clamping strip 301c, a fixing plate 301d, a clamping block 301e, a slide rail 301f, a connecting shaft 301g and a pull rod 301h. The rotating shaft 301 is located below the rotating sleeve 201, the fixing column 301a is fixed to the top of the rotating shaft 301, the supporting ball 301b is fixed to the top of the fixing column 301a, and the rotating sleeve 201 is provided with a rotating groove 201-1 at the bottom. The supporting ball 301 1b is movably connected with the rotating groove 201-1, the clamping strip 301c is fixed in the rotating groove 201-1, the supporting ball 301b is provided with a clamping slot 301b-1, the clamping strip 301c is movably connected with the clamping slot 301b-1, the fixed disk 301d is fixed to the outside of the rotating sleeve 201, the clamping block 301e is clamped to the outside of the fixed disk 301d, the sliding rail 301f is fixed to one side of the clamping block 301e, the connecting shaft 301g slides in the sliding rail 301f, and the pull rod 301h is fixed to the outside of the connecting shaft 301g.

[0039] A driving mechanism (not shown in the figure) is arranged below the rotating shaft 301, which is used to drive the rotating shaft 301 to rotate. This is the prior art and will not be elaborated in this solution. The slide rail 301f is L-shaped, and an annular groove is provided on the fixed disk 301d. The clamping block 301e is movably connected to the annular groove. The clamping block 301e can drive the fixed disk 301d to tilt downward. At the same time, when the fixed disk 301d is rotating, the position of the clamping block 301e will not be affected.

[0040] When the rotating shaft 301 rotates, it drives the fixed column 301a and the supporting ball 301b to rotate. The supporting ball 301b drives the rotating sleeve 201 to rotate through the cooperation between the clamping strip 301c and the clamping slot 301b-1, so that the rotating sleeve 201 drives the gear to rotate.

[0041] When the gear rotates a specified number of circles and the burrs on the teeth and tooth grooves are removed, the pull rod 301h will move downward and drive the block 301e to move downward through the cooperation of the connecting shaft 301g and the slide rail 301f, thereby pulling the fixed plate 301d downward to tilt through the block 301e, and driving the rotating sleeve 201 downward to tilt through the fixed plate 301d. When the rotating sleeve 201 tilts, it will also drive the gear to tilt. At this time, the top and bottom of the gear will contact the grinding blocks on both sides respectively. As the gear continues to rotate, the top and bottom of the gear can be ground and polished by the grinding blocks on both sides, and the burrs on the top and bottom of the gear can be removed. There is no need to use additional equipment to grind and polish the gear again, thereby saving operation time and processes and improving production efficiency.

[0042] Example 2

[0043] Reference Figure 1-Figure 12 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0044] Specifically, a positioning ring 202a is fixed at the bottom of the force-bearing plate 201g, a connecting block 202b is clamped on the outside of the positioning ring 202a, a pull rope 202c is fixed at the bottom of the connecting block 202b, a support column 202d is fixed to the bottom end of the pull rope 202c, a guide wheel 202e is sleeved on the outside of the pull rope 202c, the guide wheel 202e is clamped on the outside of the fixed plate 301d, and the pull rope 202c is elastic.

[0045] A snap-in groove is provided on the positioning ring 202a, and the connecting block 202b is movably connected to the snap-in groove, so that the connecting block 202b can pull the positioning ring 202a to move downward, and when the positioning ring 202a rotates, the connecting block 202b will move. The guide wheel 202e is used to position the pull rope 202c to prevent it from being offset, and the guide wheel 202e is movably connected to the outer side of the fixed plate 301d.

[0046] When the rotating sleeve 201 is tilted, it will drive the positioning ring 202a and the connecting block 202b to move upward. At this time, a downward pulling force is applied to the connecting block 202b through the pull rope 202c, and the positioning ring 202a is driven to move downward through the connecting block 202b, so that the positioning ring 202a drives the force plate 201g to move downward. When the force plate 201g moves downward, it can drive the movable column 201e to move downward, so that the rotating disk 201b can rotate again on the original basis, and the squeezing plate 201a can continue to apply squeezing force to the inside of the gear, thereby increasing the force to fix the gear and improving the stability of the gear, thereby preventing the gear from falling off when rotating in a tilted state.

[0047] Specifically, a movable sleeve 302a is sleeved on the outer side of the pull rod 301h, a first spring 302b is fixed to the bottom of the pull rod 301h, and the bottom end of the first spring 302b is fixed to the inner wall of the movable sleeve 302a.

[0048] When the movable sleeve 302a moves downward, the first spring 302b will be stretched. When the first spring 302b is stretched to a certain extent and the pull rod 301h is released from restriction, the first spring 302b can drive the pull rod 301h to move downward, thereby driving the fixed plate 301d to tilt downward through the pull rod 301h.

[0049] At this time, when the movable sleeve 302a moves upward, it will squeeze the first spring 302b. When the first spring 302b is squeezed to a certain extent and the pull rod 301h is released from restriction, the first spring 302b can push the pull rod 301h to move upward to the initial position.

[0050] Specifically, a reciprocating roller 303a is fixed to the bottom end of the movable sleeve 302a, a gear 303b is sleeved on the outside of the reciprocating roller 303a, a positioning shaft 303c is fixed inside the gear 303b, a slot 301-1 is opened on the rotating shaft 301, a tooth block 303d is inserted into the slot 301-1, the tooth block 303d is meshed with the gear 303b, and a support plate 303e is rotatably connected to the bottom of the gear 303b.

[0051] There are four slots 301 - 1 , and the tooth blocks 303 d are tightly connected to the slots 301 - 1 . The number of the tooth blocks 303 d is 1-4.

[0052] When the rotating shaft 301 rotates, the gear 303b is driven to rotate through the cooperation of the tooth block 303d. When the gear 303b rotates, the reciprocating roller 303a is driven to move downward through the cooperation of the positioning shaft 303c. In this way, the reciprocating roller 303a can drive the movable sleeve 302a to move downward, and the movable sleeve 302a can stretch the first spring 302b.

[0053] And because the number of tooth blocks 303d is between 1 and 4, the gear 303b rotates relatively slowly. Only when the rotating shaft 301 rotates multiple circles and the teeth and tooth grooves of the processed gear are ground and polished, the reciprocating roller 303a will move to the bottom and drive the pull rod 301h to move downward through the first spring 302b. At this time, the top and bottom of the processed gear can be ground and polished. At this time, when the rotating shaft 301 rotates, the reciprocating roller 303a will move upward and drive the movable sleeve 302a to squeeze the first spring 302b.

[0054] The number of tooth blocks 303d can be increased or decreased according to the actual grinding and polishing conditions of the processed gear, so that the grinding and polishing conditions of the processed gear can be adjusted according to the actual conditions.

[0055] Specifically, a support rod 304a is fixed on the top of the support plate 303e, a fixing sleeve 304b is fixed on one side of the support rod 304a, a limiting column 304c is arranged in the fixing sleeve 304b, a second spring 304d is fixed on one end of the limiting column 304c, a limiting hole 301h-1 is provided on the pull rod 301h, the limiting column 304c is engaged with the limiting hole 301h-1, and there are two limiting holes 301h-1, which are respectively located above and below one side of the pull rod 301h.

[0056] When the limiting column 304c is engaged with the limiting hole 301h-1, the pull rod 301h can be locked through the cooperation of the two, so that the pull rod 301h will move when subjected to the pulling force and pushing force of the first spring 302b. By locking the pull rod 301h, the state of the rotating sleeve 201 can also be locked to prevent the rotating sleeve 201 from being displaced when rotating.

[0057] The second spring 304d is used to apply a thrust to the limiting column 304c, so that the limiting column 304c and the limiting hole 301h-1 are more tightly engaged.

[0058] Stabilizing frames are fixed above and below one side of the support rod 304a. The two stabilizing frames are movably connected to the outside of the pull rod 301h and the movable sleeve 302a respectively to position the two and avoid deviation when the two move.

[0059] Specifically, a force block 305a is fixed on one side of the limiting column 304c, an extrusion block 305b is hinged on one side of the movable sleeve 302a through a hinge plate, a stopper 305c is fixed on one side of the movable sleeve 302a, and one side of the stopper 305c contacts and supports the extrusion block 305b.

[0060] When the movable sleeve 302a moves downward, the extrusion block 305b below will contact the force block 305a and rotate upward due to the obstruction of the force block 305a. At this time, the force block 305a will not move. When the extrusion block 305b above contacts the force block 305a, the extrusion block 305b cannot tilt due to the resistance of the stop block 305c, and then pushes the force block 305a to move, and drives the limit column 304c to separate from the limit hole 301h-1 through the force block 305a, thereby releasing the restriction on the pull rod 301h, and the pull rod 301h will move downward.

[0061] As the movable sleeve 302a continues to move downward, the upper extrusion block 305b will separate from the force-bearing block 305a. At this time, the second spring 304d applies a thrust to the limit column 304c, so that the limit column 304c can engage with the upper limit hole 301h-1, so that the pull rod 301h can be locked again.

[0062] When the movable sleeve 302a moves upward, the force-bearing block 305a can be pushed to move again through the squeezing block 305b below, and the restriction on the pull rod 301h can be released again, so that the pull rod 301h can move upward and reset.

[0063] A rotating shaft is fixed inside the upper extrusion block 305b, and a torsion spring is fixed outside the rotating shaft. One end of the torsion spring is fixed to the hinge plate, which is used to apply an upward torsional force to the upper extrusion block 305b, and the extrusion block 305b will tilt downward due to its weight.

[0064] Example 3

[0065] Reference Figure 1-Figure 12 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0066] Specifically, there are two extrusion blocks 305b, which are respectively located above and below one side of the movable sleeve 302a. The two extrusion blocks 305b are both inclined, with the lower extrusion block 305b inclined downward and the upper extrusion block 305b inclined upward.

[0067] Specifically, a third spring 201h is fixed to the bottom of the movable column 201e, and the bottom end of the third spring 201h is fixed to the inner wall of the rotating sleeve 201.

[0068] When the gear on the outer side of the rotating sleeve 201 moves upward, the third spring 201h can push the movable column 201e to return upward.

[0069] Specifically, it also includes a main body component 100, which is connected to the tilting component 300, including a base 101, a support frame 102, a cylinder 103, a motor 104 and a grinding block 105. The base 101 is arranged below the rotating shaft 301, the support frame 102 is fixed to the top of the base 101, the cylinder 103 is arranged on the top of the support frame 102, the motor 104 is connected to the output end of the cylinder 103, and the grinding block 105 is fixed to the output shaft of the motor 104.

[0070] The cylinder 103 is used to drive the motor 104 to move up and down, and the motor 104 is used to drive the grinding block 105 to rotate. The outside of the grinding block 105 is a wire brush. When the grinding block 105 moves downward and contacts the processed gear, the gear can be ground and polished, so that the burrs on the gear can be removed. This is the prior art and will not be elaborated in this scheme. The above-mentioned grinding and polishing components are in two groups, which are used to grind and polish both sides of the gear at the same time.

[0071] Specifically, the bottom end of the support column 202d is fixed to the base 101, and the support plate 303e is fixed to the top of the base 101 through the connecting column.

[0072] In summary, the grinding equipment for gear processing of the present invention has the following advantages:

[0073] 1. It can clamp and fix gears with different inner diameters;

[0074] Second, when clamping the gear, the gear can be centered so that the grinding blocks 105 on both sides can evenly contact both sides of the gear;

[0075] 3. It can drive the gear to tilt. After the teeth and tooth grooves of the gear are polished, the top and bottom of the gear can also be ground and polished;

[0076] 4. When the gear is tilted, the tightness of the gear can be further increased to prevent the gear from falling off when tilted;

[0077] 5. The time when the gear tilts can be adjusted, and the length of grinding and polishing time after tilting can be adjusted synchronously, so that the length of polishing time can be determined according to the actual polishing condition of the gear.

[0078] When in use, when the gear is placed on the outside of the rotating sleeve 201, the weight of the gear will press the force plate 201g downward, and the force plate 201g will drive the movable column 201e to move downward. At this time, the fixed shaft 201f will slide in the spiral groove 201e-1, and the cooperation of the two will drive the rotating disk 201b to rotate. At this time, the guide shaft 201d will slide in the guide groove 201b-1, and the cooperation of the two will drive the movable rod 201c and the extrusion plate 201a to move, so that the extrusion plate 201a contacts the inner wall of the gear and squeezes the inner wall of the gear, so that the gear can be fixed, and then the gear can be driven to rotate through the rotating sleeve 201, and the gear can be ground and polished. When grinding and polishing gears of different specifications, there is no need to replace the rotating mold, and it can adapt to gears of different specifications, thereby improving production efficiency.

[0079] At this time, the cylinder 103 drives the motor 104 to move downward, and the motor 104 drives the grinding block 105 to rotate. When the grinding block 105 moves downward and contacts the processed gear, the gear can be ground and polished, so that the burrs on the gear can be removed.

[0080] When the rotating shaft 301 rotates, the gear 303b is driven to rotate through the cooperation of the tooth block 303d. When the gear 303b rotates, the reciprocating roller 303a is driven to move downward through the cooperation of the positioning shaft 303c. In this way, the reciprocating roller 303a can drive the movable sleeve 302a to move downward, and the movable sleeve 302a can stretch the first spring 302b.

[0081] At the same time, when the movable sleeve 302a moves downward, the extrusion block 305b below will contact the force block 305a and rotate upward due to the obstruction of the force block 305a. At this time, the force block 305a will not move. When the extrusion block 305b above contacts the force block 305a, the extrusion block 305b cannot tilt due to the resistance of the stop block 305c, and then pushes the force block 305a to move, and drives the limit column 304c to separate from the limit hole 301h-1 through the force block 305a, thereby releasing the restriction on the pull rod 301h, and driving the pull rod 301h to move downward through the first spring 302b.

[0082] The pull rod 301h drives the block 301e to move downward through the cooperation of the connecting shaft 301g and the slide rail 301f, thereby pulling the fixed plate 301d downward to tilt through the block 301e, and driving the rotating sleeve 201 downward to tilt through the fixed plate 301d. When the rotating sleeve 201 tilts, it will also drive the gear to tilt. At this time, the top and bottom of the gear will contact the grinding blocks on both sides respectively. As the gear continues to rotate, the top and bottom of the gear can be ground and polished by the grinding blocks on both sides, and then the burrs on the top and bottom of the gear can be removed. There is no need to use additional equipment to grind and polish the gear again, thereby saving operation time and processes and improving production efficiency.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
