A Chinese patent discloses a grinding machine positioning tool, the publication number is: CN213034373U, the upper surface of the electromagnet is overlapped with a magnetic plate, the left and right sides of the upper surface of the magnetic plate are fixedly connected with sliding sleeves, and the two sliding sleeves are internally sleeved on the same sliding rod. The positioning tool of the grinder adjusts the position of the arc groove 26 on the extrusion plate 25, and then clamps the square clamping block 24 in the square clamping groove 23, and then places the workpiece on the workbench 13, and controls the output shafts of the two brake motors 17 through an external switch to rotate part of the fragments at the same time, thereby solving the problem that the positioning tool of the grinder has a simple structure and can only simply fix the blank, and cannot flexibly adjust the position according to actual conditions, which reduces the practicality of the positioning tool. In addition, the stability is not high during use, and it is easy to be unstable and shaken, which reduces the stability of the positioning tool during use. Through searching, the above is a case that is closer to the prior art. In summary, the problem of the prior art is that the positioning tool of the grinder clamps the parts by two clamping members during use, and there is no positioning anti-deviation structure on the front, rear and top sides. When the grinder processes the parts, the parts may move. Based on the search of the above patents, a grinding machine positioning tool with a positioning anti-deviation structure is specially proposed to solve the above problems. Utility Model Content

[0021] refer to Figure 2 The shape of the pressing plate 5 is L-shaped, and a cushion 7 is fixedly connected to the bottom of the pressing plate 5, and the material of the cushion 7 is rubber.

[0022] The above solution is adopted: by providing the soft pad 7, after the clamping plate moves down to clamp the material, the soft pad 7 can increase the friction between the material, so that the pressing plate 5 will not move easily, thereby increasing its stability.

[0023] refer to Figure 2 The bottom of the support block 4 is fixedly connected with a travel block 8, and the top of the connecting plate 3 is fixedly connected with a travel shell 9 used in conjunction with the travel block 8, and the travel shell 9 is slidably connected to the inner cavity of the travel groove.

[0024] The above scheme is adopted: by setting the travel block 8 and the travel shell 9, when the splint and the support block 4 move up and down, the travel block 8 and the travel shell 9 can control the moving position of the splint and the support block 4, so that the splint will not shake when moving.

[0025] refer to Figure 3 The bottom of the travel block 8 is fixedly connected with an L-shaped plate 10 , and the bottom of the L-shaped plate 10 passes through the connecting plate 3 , the travel shell 9 and the placement platform 2 and extends to the inner cavity of the bottom shell 1 .

[0026] By adopting the above solution: by setting the L-shaped plate 10, when the travel block 8 moves upward, the L-shaped plate 10 cooperates with the holes opened on the connecting plate 3, the travel shell 9 and the placement platform 2, so that the support block 4 can be stably moved.

[0027] refer to Figure 3 The left and right sides of the inner cavity of the bottom shell 1 are movably connected with screw sleeves 11, and the side of the screw sleeve 11 close to the L-shaped plate 10 is fixedly connected to the L-shaped plate 10, and the inner cavity of the screw sleeve 11 is threadedly connected with a screw rod 12.

[0028] The above solution is adopted: by setting the screw sleeve 11 and the screw rod 12, when the screw rod 12 rotates, because the screw sleeve 11 is meshed and connected with the screw rod 12, the screw sleeve 11 will move on the surface of the screw rod 12, so that the screw sleeve 11 will drive the two L-shaped plates 10 to move.

[0029] refer to Figure 3The left and right sides of the bottom of the placement platform 2 are fixedly connected with bearing seats 13, and the top of the screw rod 12 is rotatably connected to the bearing seats 13.

[0030] The above solution is adopted: by setting the bearing seat 13, when the screw 12 rotates, the bearing seat 13 can control the rotation position of the screw 12, so that the screw 12 will not shake when rotating, and the screw 12 will not rub against the inner wall of the bottom shell 1.

[0031] refer to Figure 3 The operating device 6 includes a motor 601, a first gear plate 602 and two second gear plates 603. The top of the motor 601 is fixedly connected to the placement platform 2, the output end of the motor 601 is fixedly connected to the first gear plate 602, the left and right sides of the second gear plate 603 are meshed with the second gear plate 603, and the top of the second gear plate 603 is fixedly connected to the screw 12.

[0032] The above scheme is adopted: by setting up the operating device 6, turning on the motor 601 to drive the first gear plate 602 to rotate, the rotation of the first gear plate 602 drives the second gear plate 603 to rotate, and the rotation of the second gear plate 603 drives the screw 12 to rotate in the inner cavity of the bearing seat 13, so that the two screws 12 can be driven to rotate at the same time.

[0033] The working principle of this utility model:

[0034] When in use, push the material to be processed to the bottom of the pressure plate 5, align the processed material with the pressure plate 5, and then turn on the motor 601 to drive the first gear plate 602 to rotate, the rotation of the first gear plate 602 drives the second gear plate 603 to rotate, the rotation of the second gear plate 603 drives the screw 12 to rotate in the inner cavity of the bearing seat 13, so that the screw 12 will drive the screw sleeve 11 to move downward, so that the screw sleeve 11 will drive the two L-shaped plates 10 to move downward, the movement of the L-shaped plate 10 drives the stroke block 8 to move downward in the stroke shell 9, the movement of the stroke block 8 drives the support block 4 to move, and the movement of the support block 4 drives the pressure plate 5 to clamp the material. Because the clamp is L-shaped, the material will not have a positioning anti-deviation structure.

[0035] To sum up: the grinding machine positioning tool with a positioning and anti-deviation structure is used in conjunction with the placement platform 2, the connecting plate 3, the support block 4, the pressure plate 5, the operating device 6, the soft pad 7, the stroke block 8, the stroke shell 9, the L-shaped plate 10 and the screw sleeve 11. The L-shaped plate 10 moves to drive the stroke block 8 to move downward in the stroke shell 9, and the stroke block 8 moves to drive the support block 4 to move. After the support block 4 moves to drive the pressure plate 5 to clamp the material, because the clamping plate is L-shaped, the material will not have a positioning and anti-deviation structure, which solves the problem that the existing grinding machine positioning tooling, when in use, clamps the parts by two clamping parts, and there is no positioning and anti-deviation structure on the front, rear and top sides, and the parts may move when the grinder processes the parts.
