[0003] Some fasteners such as nuts often need to be ground during processing. However, the current methods of grinding some nut-like fasteners are that workers manually lean the fasteners against the grinding disc of the grinding machine for grinding. However, this will cause the side walls of the fasteners to be ground unevenly and not be a flat surface. Content of the Utility Model
[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a grinding device for fastener processing is proposed.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

A positioning unit is arranged on one side of the grinding machine. The positioning unit includes a lower mounting plate. An upper mounting plate is slidably arranged above the lower mounting plate. A fastener body is directly clamped between the lower mounting plate and the upper mounting plate;
[0007] A servo electric cylinder is arranged at the bottom of the lower mounting plate. A screw rod is arranged on the upper surface of the lower mounting plate. Slide rods are symmetrically arranged on both sides of the screw rod on the upper surface of the lower mounting plate. The upper mounting plate is slidably arranged on the slide rods. Positioning heads are symmetrically arranged on one side of the screw rod on the upper surface of the lower mounting plate.
[0008] In addition, the preferred structure is that through holes are formed through the upper mounting plate. Slide holes are symmetrically formed on both sides of the through holes on the upper mounting plate. The screw rod is arranged at the through holes, and the slide rods are arranged at the slide holes.
[0009] In addition, the preferred structure is that a fixing component is screwed on the rod body of the screw rod above the upper mounting plate. The aperture of the through hole is larger than the major diameter of the screw rod. Positioning heads are symmetrically arranged on one side of the through hole on the bottom surface of the lower mounting plate.
[0010] In addition, a preferred structure is that the plate body of the positioning head is at a certain inclination angle, and a plurality of rubber strips are uniformly arranged on the surface of the positioning head plate body, and a fastener body is clamped between the upper and lower positioning heads.
[0011] In addition, a preferred structure is that the piston rod at the output end of the top of the servo electric cylinder is installed on the bottom surface of the lower mounting plate at the other end away from the servo electric cylinder, and a slider is arranged at the bottom of the servo electric cylinder, and a slide rail is arranged at the bottom of the slider.
[0012] In addition, a preferred structure is that the slide rail is installed on the upper surface of the workbench, and the slider is slidably arranged on the slide rail.
[0013] The beneficial effects of the present utility model are as follows: The fastener body is clamped by the provided positioning unit, and the fastener body is clamped and positioned by the positioning head between the upper mounting plate and the lower mounting plate.

Detailed Embodiments
[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0019] Refer to Figures 1-3, a grinding device for fastener processing, including a workbench 001, a grinding machine 002 is arranged on the upper surface of the workbench 001, a positioning unit 003 is arranged on one side of the grinding machine 002, the positioning unit 003 includes a lower mounting plate 4, an upper mounting plate 6 is slidably arranged above the lower mounting plate 4, a fastener body 5 is directly clamped between the lower mounting plate 4 and the upper mounting plate 6, a servo cylinder 3 is arranged at the bottom of the lower mounting plate 4, a screw rod 42 is arranged on the upper surface of the lower mounting plate 4, sliding rods 41 are symmetrically arranged on both sides of the screw rod 42 on the upper surface of the lower mounting plate 4, the upper mounting plate 6 is slidably arranged on the sliding rods 41, positioning heads 7 are symmetrically arranged on one side of the screw rod 42 on the upper surface of the lower mounting plate 4, and the lower mounting plate 4 can hold the fastener body 5.
[0020] In addition, through holes 62 are formed through the upper mounting plate 6, sliding holes 61 are symmetrically formed on both sides of the through holes 62 on the upper mounting plate 6, the screw rod 42 is arranged at the through holes 62, the sliding rods 41 are arranged at the sliding holes 61, a fixing member 8 is screwed on the rod body of the screw rod 42 above the upper mounting plate 6, the aperture of the through hole 62 is larger than the major diameter of the screw rod 42, positioning heads 7 are symmetrically arranged on one side of the through hole 62 on the bottom surface of the lower mounting plate 4, and the positioning heads 7 are used to fix the fastener body 5 to prevent it from shaking.
[0021] Moreover, the plate body of the positioning head 7 is at a certain inclination angle, and a plurality of rubber strips 71 are uniformly arranged on the surface of the plate body of the positioning head 7. The fastener body 5 is clamped between the upper and lower positioning heads 7. The rubber strips 71 prevent clamping marks from being generated when the positioning head 7 clamps, and at the same time can also increase the friction between the side wall of the fastener body 5 and the positioning head 7.
[0022] Among them, the piston rod of the top output end of the servo cylinder 3 is installed at the other end away from the servo cylinder 3 on the bottom surface of the lower mounting plate 4, a slider 2 is arranged at the bottom of the servo cylinder 3, a slide rail 1 is arranged at the bottom of the slider 2, the slide rail 1 is installed on the upper surface of the workbench 001, and the slider 2 is slidably arranged on the slide rail 1 and the slider 2 can move on the slide rail 1.
[0023] In this embodiment, when grinding the side wall of the fastener body 5 such as a nut, it can be installed at the positioning unit 003 of this device. First, loosen the fixing member 8 on the screw rod 42, so that the upper mounting plate 6 moves on the sliding rod 41, so that the distance between the upper mounting plate 6 and the lower mounting plate 4 can be enlarged. Then place the fastener body 5 between the upper and lower positioning heads 7, and then tighten the fixing member 8 on the screw rod 42, so that the upper mounting plate 6 can move downward, so as to realize that the positioning head 7 at the bottom of the upper mounting plate 6 and the positioning head 7 above the lower mounting plate 4 can jointly clamp and position the fastener body 5, and then the side wall facing the grinding machine 002 can be ground.
[0024] The slider 2 is moved to a specified position on the slide rail 1 to polish the side wall of the fastener body 5. Then, the piston rod of the servo electric cylinder 3 expands and contracts up and down, causing the upper mounting plate 6 to move linearly up and down. As a result, the grinding head of the grinding machine 002 can perform linear grinding on the side wall of the fastener body 5, ensuring that its side wall can be ground into a complete plane.
[0025] In the present utility model, the positioning unit 003 is provided to clamp the fastener body 5. The fastener body 5 is clamped and positioned by the positioning head 7 between the upper mounting plate 6 and the lower mounting plate 4. At the same time, it can also ensure that the grinding surface is parallel to the grinding machine 002. Thus, when grinding, the servo electric cylinder 3 drives the upper mounting plate 6 to move linearly up and down, enabling the grinding head of the grinding machine 002 to perform linear grinding on the side wall of the fastener body 5, ensuring that its side wall can be ground into a complete plane.
[0026] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes should be covered within the protection scope of the present utility model.
