[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. In the present invention, the first connecting rod and the third connecting rod of the device are square in shape and are used for installing a wrench. Moreover, the wrench can be adjusted 360° by directly adjusting the locking screw to adapt to the square hole size and angle differences of wrenches of different specifications.

In the present invention, the first grinding wheel and the second grinding wheel are driven to rotate by the second driving motor, the pulley and the grinding sand belt to form a continuous grinding surface. When the pressure sensor exceeds the set pressure, the third driving motor drives the first rotating gear to rotate, adjusting the wrench to approach or move away from the sand belt, so that the spring is stretched or compressed until the pressure sensor reaches the set value. The cooperation of the pressure sensor and the pressure buffer spring realizes the constant pressure grinding control, ensuring that the wrench always maintains the set pressure in contact with the grinding wheel during the grinding process, thus significantly improving the surface quality and processing efficiency of the wrench, and at the same time reducing the wear of the sand belt and the rubber wheel;

[0017] 3. In the present invention, through the design of the outer contact point plate, the problem of interference of dust on the electrical origin control during the grinding process is solved. The contact point plate extends out of the processing area, facilitating the operator to observe whether the device returns to the origin position, and at the same time avoiding the disadvantage of inconvenient observation in the closed area;

At the same time, the lower end of the second fixing table 29 is slidably connected to the upper side of the first fixing table 24.

[0040] In this embodiment, specifically: There are two groups of the second fixing tables 29 and they are vertically arranged, there are two groups of the third driving motors 25, and there are two groups of the first contact plates 31 and the second contact plates 32 respectively.

[0041] Working principle or structural principle: The wrench is fixed on the first rotating shaft 5 through the first connecting rod 6 and the third connecting rod 10. The first driving motor 3 drives the first rotating shaft 5 to rotate through the first connecting shaft 4, thereby driving the wrench to rotate around the axis. There are differences in the square hole size and angle of the wrench, and 360° adjustment can be achieved by directly adjusting the locking screw to adapt to wrenches of different specifications. The slider 8 is slidably connected to the first connecting plate 7, and the up and down movement of the wrench is realized through the second connecting rod 9 and the third connecting rod 10. The second driving motor 11 drives the second rotating shaft 15 to rotate through the pulley and the connecting belt 13, driving the first grinding wheel 16 and the second grinding wheel 18 to rotate. The grinding belt 17 is wound around the outside of the first grinding wheel 16 and the second grinding wheel 18 to form a continuous grinding surface. The air cylinder 20 adjusts the position of the second grinding wheel 18 through the second connecting plate 21 and the third rotating shaft 22 to ensure that the grinding belt 17 always contacts the surface of the wrench. The device realizes constant-pressure grinding control through the pressure sensor 33 and the pressure buffer spring 30. The third driving motor 25 drives the first circular gear 26 to mesh with the first rack 27, driving the second fixed table 29 to move along the Y-axis. The pressure buffer spring 30 presses the pressure sensor 33 to always maintain the set extrusion pressure. When the wrench contacts the grinding wheel, if the contact surface is too far from the grinding wheel, the spring pressure decreases, and the pressure sensor 33 detects that the pressure is lower than the set value. The third driving motor 25 drives the rack to move in the reverse direction along the Y-axis to increase the spring pressure; conversely, if the pressure is too high, the rack moves in the positive direction along the Y-axis to reduce the spring pressure. The device realizes the X-axis origin positioning through the contact of the first contact plate 31 and the second contact plate 32. When the two contact plates contact, the device returns to the X-axis origin to ensure the accuracy of the grinding path. Due to the large differences in the shapes of wrenches, the device first roughly designs the movement path according to the shape of the wrench, and then dynamically adjusts the grinding path through the cooperation of the pressure sensor 33 and the spring to ensure the consistency of the grinding effect. When processing wrenches of different sizes, the locking spring can be directly adjusted to quickly realize the fixture replacement of different products with a small number of parts replaced. In addition, the device can also perform a 360° quick adjustment according to the size and angle of the wrench tail hole, further improving the adaptability and processing efficiency of the device.
