[0025] The technical solutions in the embodiments of the present utility model are clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all the embodiments.

[0026] See also Figure 1-4 The utility model discloses a grinding wheel modification tool 100 and a device, which can be used to dress a defective grinding wheel 213 when the wheel surface of the grinding wheel 213 is uneven, the wheel surface structure is changed, and the like.

[0027] On the one hand, if Figure 3 and Figure 4As shown, the grinding wheel modification tool 100 includes: a mounting handle 101, a movable portion 103, a modification needle 105 and a driving device 107. Among them, a C-shaped mounting portion 102 is provided at one end of the mounting handle 101, and the C-shaped opening direction of the mounting portion 102 faces the direction away from the end of the mounting portion 102; the movable portion 103 is C-shaped, and the two ends of the C-shaped opening of the movable portion 103 are rotatably connected to the two ends of the C-shaped opening of the mounting portion 102 through a rotating shaft 104; Figure 3 As shown, the overall structure of the movable portion 103 is smaller than the C-shaped inner groove of the mounting portion 102 , so that the movable portion 103 can swing in the C-shaped inner groove structure of the mounting portion 102 .

[0028] The modification needle 105 is arranged at the bottom of the C-shaped groove structure of the movable part 103, and the needle tip 106 of the modification needle 105 faces the C-shaped opening direction of the movable part 103; the driving device 107 includes a rotatable mounting shaft 108 arranged at one end of the mounting part 102, and the mounting shaft 108 is provided with a handle 111 and a first gear 109, the handle 111 is used to rotate the mounting shaft 108, and the second gear 112 is arranged on the rotating shaft 104 adjacent to the mounting shaft 108 and meshes with the first gear 109.

[0029] Reference Figure 1 and Figure 2 As shown, the grinding wheel modification tool 100 of the utility model provides an auxiliary device for correcting the contour of the wheel surface of the defective grinding wheel 213. When using it, the grinding wheel 213 to be repaired is first set on the rotating device 203, such as a motor, so that the grinding wheel 213 can rotate at high speed, and then the mounting handle 101 is fixed, so that the needle tip 106 of the modification needle 105 points to and approaches the outer circular contour position of the grinding wheel 213, and the operator shakes the handle 111 to control the modification needle 105 to shake in a specific posture to repair the grinding wheel 213, and repairs a specific arc surface on the wheel surface of the grinding wheel 213, so as to facilitate the use of the modified grinding wheel 213 for product surface structure processing.

[0030] Among them, the number of teeth of the first gear 109 is less than the number of teeth of the second gear 112, so that when the handle 111 is rotated to drive the modification needle 105 to swing, the swing arc of the modification needle 105 is decelerated, that is, when the hand needs to operate the handle 111 to swing with a larger arc, the swing arc of the modification needle 105 is smaller than the swing arc of the handle 111, and the swing speed is also smaller than the swing speed of the handle 111. The characteristic is that through the reduction transmission, it is convenient to manually control the swing of the modification needle 105, so that the modification needle 105 can slowly pass through the wheel surface of the grinding wheel 213 for processing, thereby avoiding the modification needle 105 moving too fast to cause the needle to hit, and also affecting the processing effect.

[0031] Furthermore, the needle tip 106 of the needle 105 is made of wear-resistant diamond material.

[0032] The handle 111 is detachably connected to the mounting shaft 108. Specifically, the two ends of the mounting shaft 108 extend toward the two sides of the end of the movable part 103, respectively. The first gear 109 is arranged at one end of the mounting shaft 108 in the direction of the C-shaped groove structure extending to the mounting part 102; the other end is provided with a polygonal protrusion 110 extending coaxially with the mounting shaft 108, and the end of the handle 111 in the direction of connecting the mounting shaft 108 is provided with a polygonal groove 113, and the polygonal groove 113 is sleeved with the polygonal protrusion 110. When not in use, the polygonal groove 113 can be pulled off the polygonal protrusion 110 to achieve disassembly, which is convenient to operate.

[0035] The connecting device 205 includes a column 206, on which an extension arm 209 is provided, the length direction of the extension arm 209 is parallel to the driving shaft 204, the position of the extension arm 209 can be adjusted along the length direction of the extension arm 209 on the column 206, and a mounting seat 210 is provided at one end of the extension arm 209 close to the driving device 107, and a first slot 211 is provided on the mounting seat 210, and a first screw 212 threadedly matched with the first slot 211 is provided on one side of the first slot 211, one end of the first screw 212 extends into the first slot 211, and the mounting handle 101 is inserted into the first slot 211. Rotating the first screw 212 can make the end of the first screw 212 press against the mounting handle 101 to fix the mounting handle 101. In this case, the mounting position of the mounting handle 101 can also be adjusted by loosening the first screw 212.

[0036] The upper end of the column 206 is provided with a second slot 207, and the upper end of the column 206 is provided with a second screw 208 threadedly matched therewith, one end of the second screw 208 extends to the second slot 207, and the extension arm 209 is inserted into the second slot 207. Rotating the second screw 208 can make the end of the second screw 208 press against the extension arm 209 to fix the extension arm 209. In this case, the position of the extension arm 209 can be adjusted by loosening the second screw 208.

[0037] By coordinating the adjustable position of the mounting handle 101 and the adjustable position of the extension arm 209, the relative position between the needle 105 and the grinding wheel 213 can be adjusted, and the swinging posture of the needle 105 can be adjusted, so as to process the wheel surface structure of the grinding wheel 213 with different curvatures.
