Figure 1 , the removable tool 30 is a single side cross-sectional view.

[0043] The tool holder 20 includes a main body 21, a trigger 23, a ball (retaining body) 25, a push rod 27, and a spring 29.

[0044] The main body 21 includes a shank 21a, a tool mounting hole 21c, a ball hole 21d, a spring chamber 21f, and a tip end face 21g (refer to Figure 3 ). The main body 21 is, for example, installed to a spindle of a machine tool (not shown) to rotate around a center axis 1. The shank 21a, the tool mounting hole 21c, and the spring chamber 21f are arranged along the center axis 1. The tool mounting hole 21c is arranged at a tip end of the main body 21. The tool mounting hole 21c is open at the tip end of the main body 21. The spring chamber 21f is connected to the tool mounting hole 21c. The ball hole 21d penetrates the main body 21 in a radial direction. The tip end face 21g is a plane perpendicular to the center axis 1 and is arranged at the tip end of the main body 21.

[0045] As shown in Figure 5As shown, the main body 21 has a mounting direction mark 21h. The mounting direction mark 21h is disposed near the opening of the tool mounting hole 21c. For example, the mounting direction mark 21h is disposed at the top end of the main body 21. For example, the mounting direction mark 21h is disposed on the outer peripheral surface of the main body 21. The mounting direction mark 21h may also be disposed on the top surface 21g of the main body 21. The mounting direction mark 21h extends parallel to the central axis 1. The mounting direction mark 21h may also be an arrow pointing towards the top surface 21g or an isosceles triangle having a vertex pointing towards the top surface 21g. The mounting direction mark 21h is formed, for example, by printing or laser marking.

[0046] Furthermore, the main body 21 can be supported on the outer casing (not shown) in a rotatable manner around the central axis 1. The outer casing is disposed at the tip of the robot's arm. At this time, the main body 21 is connected to a motor (not shown) disposed on the outer casing.

[0047] like Figure 1 As shown, the ball 25 is inserted into the ball hole 21d.

The trigger member 23 includes a pressing surface 23a and a clearance portion 23b. The trigger member 23 reciprocates between the machining position 3 and the loading / unloading position 5. When the trigger member 23 is in the machining position 3, the pressing surface 23a causes the ball 25 to protrude into the tool mounting hole 21c. When the trigger member 23 is in the loading / unloading position 5, the ball 25 is housed in the clearance portion 23b.

[0049] Spring 29 is a compression helical spring. Spring 29 is disposed in spring chamber 21f. Push rod 27 reciprocates inside tool mounting hole 21c. Push rod 27 is exerted with force by spring 29 toward its tip.

[0050] like Figure 1 and Figure 2 As shown, the loading / unloading tool 30 includes a housing 31, balls (anti-rotation components) 33, ball rings 35, a slider 36, and a spring (elastic body) 39. All components constituting the loading / unloading tool 30 are arranged around the central shaft 1.

[0051] The housing 31 includes a housing main body 31a, a small cylinder portion 31b, a retainer insertion hole (retainer accommodating portion) 31c, a ball retaining hole 31d, a spring chamber (elastic body chamber) 31f, and a rod hole 31h. The housing 31 is hollow and cylindrical. The outer cylinder surface of the housing main body 31a abuts against the tool mounting hole 21c. The small cylinder portion 31b extends from the top end portion of the housing main body 31a. The retainer insertion hole 31c is provided on the outer cylinder surface of the housing main body 31a. The retainer insertion hole 31c is semispherical and has substantially the same diameter as the ball 25. The retainer insertion hole 31c abuts against the ball 25. The spring chamber 31f is cylindrical and opens at the base end portion of the housing main body 31a. The spring chamber 31f can also have a large diameter portion 31f1 and a small diameter portion 31f2. The small diameter portion 31f2 is provided in the top end direction of the large diameter portion 31f1. The rod hole 31h extends from the top end portion of the housing 31 along the center axis 1. The rod hole 31h is connected to the spring chamber 31f.

[0052] The ball 33 is inserted into the ball retaining hole 31d. The ball ring 35 is provided on the small cylinder portion 31b and retains the ball 33.

[0053] The slide 36 includes a sliding main body 37, a rod 38, a guide groove 40, and a spring receiving portion (elastic body receiving portion) 41.

[0054] The sliding main body 37 is straight and cylindrical. The sliding main body 37 includes a sliding surface 37a, a tool hole 37b, and a scale 39. The sliding surface 37a slides within the tool mounting hole 21c. The tool hole 37b is provided on the top end portion of the sliding main body 37.

[0055] The scale 39 includes a shortened end scale 39a, an elongated end scale 39c, and one or more intermediate scales 39b. The scale 39 can also have an alignment direction mark 39d. The shortened end scale 39a, the elongated end scale 39c, and the one or more intermediate scales 39b each extend perpendicularly to the center axis 1. The shortened end scale 39a coincides with the top end surface 21g when the tool changer 30 is mounted to the tool holder 20. The elongated end scale 39c coincides with the top end surface 21g when the tool changer 30 is mounted to the tool holder 20 and the tool changer 30 is fully extended from the tool holder 20. The intermediate scales 39b are provided between the shortened end scale 39a and the elongated end scale 39c at equal intervals. The alignment direction mark 39d is an isosceles triangle with the apex facing the base end direction. The scale 39 is formed, for example, by printing or laser marking.

[0056] When the tool changer 30 is mounted to the tool mounting hole 21c, it is inserted in such a manner that the position of the scale 39 coincides with the apex of the mounting direction mark 21h. It is preferable to insert the tool changer 30 with the alignment direction mark 39d aligned with the mounting direction mark 21h. At this time, the ball 25 is inserted into the retainer insertion hole 31c and the tool changer 30 is mounted to the tool holder 20.

[0057] Further, the shape of the intermediate scale 39b can be an arrowhead shape, a circle, an ellipse, or a polygon. The length of the intermediate scale 39b can also become longer, thicker, or larger toward the direction of the top end of the slider 36.

[0058] In addition, an alignment direction mark 39d can also be provided to the housing 31. The alignment direction mark 39d can also be a straight line parallel to the central axis 1.

[0059] The rod 38 is provided to the base end portion of the sliding body 37. The rod 38 is a straight cylinder. The rod 38 includes a sliding shaft 38a, an abutting cylinder portion 38b, and an external thread 38c.

[0060] A plurality of (two in this embodiment) guide grooves 40 are formed in the sliding shaft 38a rotationally symmetrically with respect to the central axis 1. The guide grooves 40 extend in a spiral shape with the central axis 1 as the center. The guide grooves 40 have a lead angle a.

[0061] Further, the guide grooves 40 can also extend linearly along the central axis 1.

[0062] The spring receiving portion 41 is connected to the base end portion of the rod 38. The spring receiving portion 41 includes a support portion 41a, a shaft portion 41b, an inner cylinder portion 41d, and an internal thread 41c. The diameter of the support portion 41a is larger than the outer diameter of the spring 39. It is preferable that the support portion 41a slide within the large diameter portion 31fl of the spring chamber 31f. The outer diameter of the shaft portion 41b is smaller than the inner diameter of the spring 39. The outer diameter of the shaft portion 41b is substantially equal to the outer diameter of the sliding shaft 38a. The inner cylinder portion 41d abuts against the abutting cylinder portion 38b. The internal thread 41c is fastened to the external thread 38c of the rod 38.

[0063] The slider 36 is guided by the guide grooves 40 by the balls 33 and advances and retreats in the direction of the central axis 1 in the housing 31 in a spiral shape.

[0064] The top end tool 43 includes a shank portion 43a, a reduced diameter portion 43b, and a blade portion 43c. The blade portion 43c is supported to the shank portion 43a via the reduced diameter portion 43b. The blade portion 43c has a cutting edge in the base end direction. The shank portion 43a is fastened to the tool hole 37b.

[0065] The spring 39 is a compression coil spring. The spring 39 is inserted into the gap between the spring chamber 31f and the rod 38. The spring receiving portion 41 is fastened to the rod 38, whereby the spring 39 is supported. The spring 39 is guided by the sliding shaft 38a, the shaft portion 41b, or the small diameter portion 31f2. The spring 39 exerts a force on the slider 36 in the base end direction.

[0066] Figure 3 A use condition of the processing tool 10 in which the detachable tool 30 is attached is shown. Figure 3The right half of FIG. 10 shows a state where the slider 36 is located at the base end. Figure 3 The left half of FIG. 10 shows a state where the slider 36 is moved toward the tip end to remove the burr of the workpiece 7.

[0067] The processing tool 10 is rotated in the -θ direction. The slider 36 is moved so that the blade portion 43c comes into abutment with the edge of the back surface of the workpiece 7 as viewed from the tool holder 20. The processing tool 10 is moved in a direction perpendicular to the paper surface. The housing 31 is supported at a fixed position by the ball 25. The spring 29 is kept in a contracted state. The slider 36 is urged toward the base end direction by the elastic force of the spring 39. The slider 36 is guided by the guide groove 40. When the edge height of the workpiece 7 abutted by the blade portion 43c changes in conjunction with the movement of the processing tool 10, the spring 39 is stretched and contracted, and the slider 36 slides within the tool mounting hole. Here, the ball 33 and the guide groove 40 guide the slider 36. Since the guide groove 40 has the lead angle α, the slider 36 advances and retreats depending on the magnitude of the cutting torque received by the blade portion 43c.

[0068] As shown in FIGS. 11 and 12, the tool holder 20 is capable of mounting the slide tool 50 in place of the detachable tool 30. Here, Figure 4 The right half of FIG. 13 shows a state where the slide tool 50 is mounted to the tool holder 20 to process the workpiece 7. Figure 5 The left half of FIG. 13 shows a state where the slide tool 50 is detached from the tool holder 20. Figure 4 Figure 4 As shown in FIGS. 14 and 15, the slide tool 50 includes a slide main body 51, a tip end tool 53, a guide groove 52, and a scale 59 (see FIG. 16).

[0069] As shown in FIGS. 14 and 15, the slide tool 50 includes a slide main body 51, a tip end tool 53, a guide groove 52, and a scale 59 (see FIG. 16). Figure 4 Figure 5 The slide main body 51 is a straight cylindrical shape and slides along the axial direction of the tool mounting hole 21c. The guide groove 52 extends in parallel with the center axis 1. Figure 5

[0070] As shown in FIGS. 14 and 15, the slide tool 50 includes a slide main body 51, a tip end tool 53, a guide groove 52, and a scale 59 (see FIG. 16). Figure 5 ​​​As shown, the scale 59 includes a middle scale 59b and an alignment direction mark 59d. The middle scale 59b is substantially the same as the middle scale 39b. However, the length of the middle scale 59b increases as it approaches the top. When the sliding tool 50 is mounted in the tool mounting hole 21c, the alignment direction mark 59d coincides with the mounting direction mark 21h. The alignment direction mark 59d is a straight line extending parallel to the central axis 1. When the sliding tool 50 is mounted on the tool holder 20, the base end of the alignment direction mark 59d coincides with the top surface 21g. When the sliding tool 50 is mounted on the tool holder 20 and the sliding tool 50 is fully retracted, the top end of the alignment direction mark 59d coincides with the top surface 21g. That is, the alignment direction mark 59d serves as both an extended end scale and a shortened end scale. The top tool 53 is mounted on the sliding body 51. The top tool 53 has a cutting edge portion 53a. The cutting edge portion 53a has a cutting edge in the top direction. The sliding body 51 is forced towards its tip by the push rod 27. The cutting direction 2 of the sliding tool 50 is towards... Figure 4 The downward direction.

[0071] Reference Figure 4 The processing tool 10 is rotated as a whole. Then, while moving vertically along the paper surface, the processing tool 10 brings the top tool 53 into contact with the workpiece 7. Then, burrs are removed from the edge of the workpiece 7 on the tool holder 20 side, i.e., the surface side of the workpiece 7. As the distance (height) between the workpiece 7 and the tool holder 20 changes, the sliding tool 50, in conjunction with the height of the workpiece 7, reciprocates within the tool mounting hole 21c, integrally with the push rod 27. At this time, the ball bearing 25 and the guide groove 52 guide the sliding body 51.

[0072] Figure 6 A sliding cutter 150 is shown as a variation of the sliding cutter 50. The sliding cutter 50 includes a sliding body 51, a top cutter 53, a guide groove 152, and a graduation 159. The sliding cutter 150... Figure 4 When viewed from above, the guide groove 152 experiences cutting resistance in a counter-clockwise direction. The guide groove 152 advances in a direction opposite to the rotation direction of the cutting tool 10 (+θ), and is oriented in a direction opposite to the cutting direction 2 (...). Figure 6 The spiral (upper middle) is present. The other construction of the guide groove 152 is substantially equivalent to that of the guide groove 40 of the loading / unloading tool 30. However, the ball 25 is inserted into the guide groove 152. The scale 159 includes a center scale 159b and an alignment direction mark 159d. The center scale 159b is of equal length to each other. The alignment direction mark 159d is substantially equal to the alignment direction mark 59d.

[0073] When the operator creates and confirms the motion trajectory of the tool holder, the operator needs to adjust the motion of the robot or machine tool so that the forward and backward movement of the slider 36 falls within the expected range.

[0074] According to the processing tool 10 of the present embodiment, the operator can visually confirm the amount of advance and retreat of the detachable tool 30 with respect to the tool holder 20 from the scale 39. Therefore, the teaching work of the robot becomes easy for the operator.

[0075] As the slide tool 50 is retracted, the length of the middle scale 59b at the position where the scale 59 comes into contact with the top face 21g becomes longer. Therefore, the operator can avoid misreading the middle scale 59b. Also, the operator easily grasps the amount of advance and retreat of the slide 36.

[0076] In addition, when the height of the workpiece 7 varies, the slide 36 can perform the chamfering processing of the fixed amount regardless of the variation in the height of the workpiece 7 by advancing and retreating. Therefore, the operator needs to confirm the extension and retraction allowance of the slide 36 when performing the programming work of the machine tool or the teaching work of the robot. In the processing tool 10, the scale 39 includes the shortened end scale 39a and the lengthened end scale 39c. Therefore, the operator can visually confirm the limit of the advance and retreat stroke of the slide 36 during the teaching. Also, the operator can easily confirm the extension and retraction allowance of the slide 36.

[0077] The slide 36 has the scale 39 including the lengthened end scale 39c. Therefore, the operator can suppress the use case exceeding the extension and retraction limit of the slide 36. Also, the breakage of the top tool 43, the detachable tool 30, or the processing tool 10 can be suppressed.

[0078] Sometimes, the insertion of the detachable tool 30 into the narrow portion such as the hole of the workpiece 7 can cause the blade portion 43c to collide with the back surface of the narrow portion. At this time, there is a case where it is difficult to see whether the blade portion 43c touches the edge of the back surface of the narrow portion. At this time, since the slide 36 has the scale 39, the operator can easily confirm whether the slide 36 is advancing and retreating when the slide 36 is advanced and retreated or the tool holder 20 is moved. If the slide 36 is advancing and retreating, it can be confirmed that the blade portion 43c has touched the edge.

[0079] When the detachable tool 30 is installed in the tool holder 20, it is necessary to insert the detachable tool 30 into the tool mounting hole 21c in such a manner that the position of the holding body insertion hole 31c and the ball 25 coincide. The tool holder 20 has the installation direction mark 21h, and the detachable tool 30 has the alignment direction mark 39d. Therefore, the operator can install the detachable tool 30 in the tool holder 20 in such a manner that the alignment direction mark 39d coincides with the installation direction mark 21h. Therefore, the operator can easily install the detachable tool 30 in the tool holder 20.

[0080] The slide tool 50 has an alignment direction mark 59d. The operator can insert the slide tool 50 into the tool mounting hole 21c of the tool holder 20 in such a manner that the alignment direction mark 59d coincides with the mounting direction mark 21h.

[0081] The slide tool 50 has a scale 59. The slide tool 150 has a scale 159. Their effects are substantially the same as those of the removable tool 30.

[0082] The utility model is not limited to the above-mentioned embodiment, can carry out various deformation in the range without departing from the utility model essential, all technical matters contained in the technical idea recorded in the claim are the object of the utility model. The embodiment shows the preferred example, but as long as the person skilled in the art can realize various alternative examples, correction example, modification example or improvement example based on the content disclosed in the specification, they are contained in the technical range recorded in the claim.
