[0027] The utility model provides Figure 1 A fast-adjustable claw corrector shown includes a fixing mechanism 1 and further includes:

[0028] The mounting mechanism 2 is arranged on the top of the fixing mechanism 1 and is used to connect and fix the fixing mechanism 1 with the claw.

[0029] In order to facilitate the adjustment according to the position of the claw, the corrector is stably connected to the claw, such as Figure 2-3 and Figure 5As shown, the mounting mechanism 2 includes a rotating gear ring 201, which is arranged at the outer bottom of the fixing mechanism 1, and three driven gears 202 are meshed at the top of the rotating gear ring 201, and a rotating sleeve 203 is fixedly inserted into the inner wall of the three driven gears 202, and a movable screw 204 is threadedly inserted into the inner wall of the rotating sleeve 203, and a movable seat 205 is fixedly installed at one end close to the three movable screws 204, and a traction spring 209 is arranged between the movable seat 205 and the inner wall of the fixing mechanism 1, and a positioning pin 208 is arranged on the top of the three movable seats 205. The rotation of the rotating gear ring 201 causes the three driven gears 202 to rotate, and then under the action of the threaded connection between the rotating sleeve 203 and the movable screw 204, the positions of the three positioning pins 208 can be adjusted so that the positioning pins 208 are stably connected to the claws.

[0030] In order to keep the rotating gear ring 201 stable during the rotation process, Figure 2-4 As shown, the fixing mechanism 1 includes a fixing ring 101, a supporting ring 102 is fixedly installed on the outer bottom of the fixing ring 101, and the top of the supporting ring 102 is movably connected to the rotating gear ring 201. The fixing ring 101 can install and fix the mounting mechanism 2, and the supporting ring 102 can support and limit the rotation of the rotating gear ring 201, so that the rotating gear ring 201 remains stable during the movement.

[0031] In order to keep the positioning pin 208 stable during the movement, Figure 2-4 As shown, the outer wall of the fixed ring 101 is provided with three mounting grooves 104 in an annular shape at equal intervals, and the inner walls of the three mounting grooves 104 are rotatably connected to the three rotating sleeves 203 respectively; the top of the fixed ring 101 is provided with three movable grooves 103 in an annular shape at equal intervals, and the three movable grooves 103 are respectively connected to the three mounting grooves 104; the inner wall of the movable groove 103 is movably connected to the outer wall of the adjacent movable seat 205; the inner wall of one end of the movable groove 103 close to the mounting groove 104 is fixedly connected to the adjacent traction spring 209; the end of the traction spring 209 away from the inner wall of the movable groove 103 is fixedly connected to the adjacent movable seat 205; the traction spring 209 is movably sleeved on the outside of the adjacent movable screw 204; the movable groove 103 and the traction spring 209 can pull and limit the movement of the adjacent movable seat 205, so that the positioning pin 208 remains stable during the movement.

[0032] In order to make the positioning pin 208 move stably along the top surface of the fixing ring 101, as shown in FIG. Figure 2As shown, a fixing plate 207 is fixedly installed on the top of each of the three movable seats 205. The top of the fixing plate 207 is fixedly connected to the bottom of an adjacent positioning pin 208. The width dimension of the fixing plate 207 is larger than the width dimension of the adjacent movable groove 103. The fixing plate 207 can install and fix the positioning pin 208. At the same time, the fixing plate 207 can move along the surface of the fixing ring 101 to limit the movement of the positioning pin 208.

[0033] In order to prevent the movable screw 204 from being separated from the inside of the rotating sleeve 203, as shown in FIG. Figure 2 and Figure 5 As shown, a limiting plate 206 is fixedly installed at one end of the movable screw 204 away from the movable seat 205. The diameter of the limiting plate 206 is larger than the diameter of the rotating sleeve 203. The limiting plate 206 can limit the movement of the movable screw 204 and prevent the movable screw 204 from escaping from the rotating sleeve 203.

[0034] The specific implementation method is as follows: when correcting the three-jaw chuck, the rotating gear ring 201 is rotated according to the position of the claws, and through the meshing action between the gear parts, the three driven gears 202 are rotated, which can then drive the three rotating sleeves 203 to rotate, and through the threaded connection between the rotating sleeve 203 and the movable screw 204, the movable screw 204 can drive the movable seat 205 to move along the inner wall of the movable groove 103, and at the same time can drive the traction spring 209 to extend or contract, so that the distance between the three locating pins 208 can be adjusted, and then the three locating pins 208 are respectively inserted into the grooves on the outside of the three claws, so that the inner side of the claw can pass through the inner side of the fixed ring 101, so that the staff can conveniently correct the working end face of the claw through the tool, which can ensure the stable progress of the claw correction work. This implementation method specifically solves the problem in the prior art that the corrector cannot be conveniently adjusted according to the position of the claw, which will affect the efficiency of the claw correction.

[0035] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
