DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-4, the present utility model discloses a grinding jig for metal products, including a grinding table 1. An installation plate 2 is installed on the top of the grinding table 1. Two driving rollers 3 driven by a motor are rotatably connected to the installation plate 2. A sand belt 4 for grinding is drivingly connected between the two driving rollers 3. Two movable plates 5 are movably connected to the top of the installation plate 2. A tensioning roller 6 for tensioning the sand belt 4 is rotatably provided at one end of the top of the movable plate 5. A fixing frame 7 integrally in a U shape is installed on the top of the grinding table 1 on one side of the installation plate 2. A lead screw 8 driven by a motor is rotatably connected to the fixing frame 7. A support plate 9 is threadedly connected to the lead screw 8. A fixing bracket 10 in an L shape is fixedly connected to the side of the top of the support plate 9 close to the installation plate 2. A limiting mechanism for limiting the metal product is provided on the fixing bracket 10.

[0019] Specifically, a linear guide rail 13 is installed on the fixing frame 7 below the lead screw 8. A slider slidably connected to the linear guide rail 13 is installed at the bottom of the support plate 9.

[0020] In this embodiment, the cooperation of the linear guide rail 13 and the slider is to guide the movement of the support plate 9.

[0021] Specifically, the limiting mechanism includes a cylinder 11 and a limiting plate 12. A cylinder 11 is installed on the top of the fixing bracket 10. The output shaft of the cylinder 11 penetrates through the fixing bracket 10 and is connected to the limiting plate 12.

[0022] Guide rods 19 penetrating through the fixing bracket 10 are movably provided on both sides of the cylinder 11 at the top of the fixing bracket 10. The bottom ends of the guide rods 19 are fixedly connected to the limiting plate 12.

[0023] In this embodiment, the lifting of the limiting plate 12 can press the metal product placed on the support plate 9.

[0024] Linear bearings cooperating with the guide rods 19 are installed on the top of the fixing bracket 10.

[0025] Specifically, a strip groove 14 is formed on the top of the movable plate 5. A screw rod 15 that can pass through the strip groove 14 is fixedly connected to the top of the installation plate 2. A nut 16 is threadedly connected to the part of the screw rod 15 passing through the strip groove 14. The two movable plates 5 are connected by a connecting plate 17.

[0026] In this embodiment, the screw rod 15 is fixed. The movable plate 5 can displace relative to the screw rod 15 through the strip groove 14 through which it is penetrated by the screw rod 15, and then the tensioning roller 6 is used to tension the sand belt 4.

[0027] Tightening the nut 16 can limit the displacement of the movable plate 5.
