[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in this embodiment, a grinding fixture for metal product processing includes a base 1 and a mounting base 2. The base 1 is equipped with a mounting frame 3, which is rotatably connected to the base 1 via a mounting rod 11. Below the mounting frame 3 are two symmetrically distributed mounting boxes 8, each containing a grinding disc 9. The mounting boxes 8 are slidably connected to the mounting frame 3. The mounting frame 3 contains a first cylinder 10. A fixing frame 7 is fixedly mounted on the base 1, corresponding to the mounting frame 3. An adjusting seat 4 is slidably mounted above the base 1, and the mounting base 2 is slidably connected to the adjusting seat 4. The base 1 contains a first lead screw 5, the adjusting seat 4 contains a second lead screw 6, and the mounting base 2 contains four symmetrically distributed clamping rods 15. A first gear 12 is fitted onto the base 1, a first rack 13 is provided inside the base 1, a movable seat 20 is slidably mounted on the fixed frame 7, a brush 24 is rotatably mounted on the movable seat 20, a second gear 25 is fitted onto the brush 24, and a second rack 26 is slidably mounted inside the movable seat 20. Under the action of the first cylinder 10, the mounting box 8 aligned with the mounting base 2 and the grinding disc 9 below the mounting box 8 are pushed onto the metal product fixed on the mounting base 2. The motor inside the mounting base 2 is started to drive the rotation of the grinding disc 9, realizing the grinding process of the metal product. The mounting box 8 is connected to the output end of the piston rod of the first cylinder 10. The two ends of the first lead screw 5 pass through the base 1 and are rotatably connected to the base 1. The first lead screw 5 passes through the adjusting seat 4 and is connected to the adjusting seat 4. The second lead screw 6 is threaded, with both ends passing through the adjusting seat 4 and rotatably connected to it. The second lead screw 6 also passes through the mounting seat 2 and is threadedly connected to it. During the metal product grinding process, the motor inside the base 1 is activated to rotate the first lead screw 5. Under the limiting action of the base 1, the adjusting seat 4 drives the mounting seat 2 and the metal product to slide longitudinally at a uniform speed. Subsequently, the motor inside the adjusting seat 4 is activated to rotate the second lead screw 6, causing the mounting seat 2 to drive the metal product to slide laterally at a uniform speed on the adjusting seat 4. This ensures that all surfaces of the metal product receive a uniform grinding effect. The grinding disc 9 is correspondingly positioned to the mounting seat 2. The mounting seat 2 contains two sets of symmetrically distributed first adjusting rods 16 and second adjusting rods 17. Both adjusting rod 16 and the second adjusting rod 17 are slidably connected to the mounting base 2. The first adjusting rod 16 and the second adjusting rod 17 are perpendicularly distributed. The clamping rod 15 is slidably sleeved with the adjacent first adjusting rod 16 and the second adjusting rod 17 respectively. Two sets of symmetrically distributed first bidirectional screws 18 and second bidirectional screws 19 are rotatably installed inside the mounting base 2. For different models of metal products, the first bidirectional screws 18 and the second bidirectional screws 19 can be rotated by the motor inside the mounting base 2 respectively. Under the limiting action of the mounting base 2, the positions of the two sets of first adjusting rods 16 and the two sets of second adjusting rods 17 can be adjusted, thereby controlling the four sets of clamping rods 15 to slide synchronously inward or outward, clamping the metal product at the center position of the mounting base 2.To ensure uniform grinding of various positions of metal products, different models are held in the center position on the mounting base 2, the first lead screw 5 and the second lead screw 6 are used. The two ends of the two sets of first bidirectional screws 18 pass through the two corresponding sets of first adjusting rods 16 and are threadedly connected to them. Similarly, the two ends of the two sets of second bidirectional screws 19 pass through the two corresponding sets of second adjusting rods 17 and are threadedly connected to them.

[0024] like Figure 5 and Figure 6 As shown, a second cylinder 14 is provided inside the base 1. The first rack 13 is meshed with the first gear 12. The first rack 13 is slidably connected to the base 1. The first rack 13 is connected to the output end of the piston rod of the second cylinder 14. After a set of grinding discs 9 has been used for a period of time, the second cylinder 14 is activated to drive the first rack 13 to slide inside the base 1. This, in conjunction with the first gear 12, causes the mounting rod 11 to rotate the mounting frame 3 by 180 degrees, completing the position conversion of the two sets of mounting boxes 8 and the grinding discs 9 below the mounting boxes 8. The converted grinding discs 9 are aligned with the brush 24. Without affecting the normal operation of the other set of grinding discs 9, the fixed frame 7 is provided with two sets of symmetrically distributed fixed rods 21. Springs 22 are sleeved on the fixed rods 21. Cams 23 are rotatably mounted on the fixed frame 7. The movable seat 20 is slidably sleeved with the fixed rods 21. The two ends of the springs 22 are fixedly connected to the movable seat 20 and the fixed frame 7, respectively. The cams 23 are in contact with the movable seat 20. The fixed frame 7 is activated. The motor inside drives the cam 23 to rotate and pushes the moving seat 20. As the moving seat 20 slides on the fixed rod 21, it compresses and stretches the spring 22. The push of the cam 23 causes the brush 24 to vibrate left and right. A flying disc 27 is rotatably installed inside the moving seat 20. A connecting rod 28 is provided inside the moving seat 20. The two ends of the connecting rod 28 are rotatably connected to the flying disc 27 and the second rack 26 through a rotating shaft, respectively. The second rack 26 is meshed with the second gear 25. At the same time, the motor inside the moving seat 20 is started to drive the flying disc 27 to rotate. The connecting rod 28 drives the second rack 26 to slide back and forth inside the moving seat 20. The second gear 25, which is meshed with the second rack 26, drives the brush 24 to sweep back and forth on the surface of the grinding disc 9 to clean the metal debris adhering to the surface of the grinding disc 9. At the same time, as the moving seat 20 drives the brush 24 to vibrate, the metal debris cleaned by the brush 24 is shaken off to prevent the metal debris from re-adhering to the grinding disc 9.

[0025] This utility model provides a grinding fixture for metal product processing. The specific working principle is as follows: Under the action of the first cylinder 10, the mounting box 8 aligned with the mounting base 2 and the grinding disc 9 below the mounting box 8 are pushed onto the metal product fixed on the mounting base 2. The motor inside the mounting base 2 is started to drive the grinding disc 9 to rotate, thus achieving grinding processing of the metal product. During the grinding process, the motor inside the base 1 is started to drive the first lead screw 5 to rotate. Under the limiting action of the base 1, the adjusting seat 4 drives the mounting base 2 and the metal product to slide longitudinally at a uniform speed. Subsequently, the motor inside the adjusting seat 4 is started to drive the second lead screw 6. The rotation causes the mounting base 2 to slide the metal product laterally at a uniform speed on the adjusting base 4, thus ensuring that all surfaces of the metal product receive a uniform polishing effect. For different models of metal products, the motor inside the mounting base 2 can drive the rotation of the first bidirectional screw 18 and the second bidirectional screw 19 respectively. Under the limiting action of the mounting base 2, the positions of the two sets of first adjusting rods 16 and the two sets of second adjusting rods 17 are adjusted, thereby controlling the four sets of clamping rods 15 to slide synchronously inward or outward, clamping the metal product at the center position of the mounting base 2, and maintaining the center position of different models of metal products on the mounting base 2. The clamping mechanism, using the first lead screw 5 and the second lead screw 6, achieves uniform grinding of various positions on the metal product. After a set of grinding discs 9 has been used for a period of time, the second cylinder 14 is activated, causing the first rack 13 to slide within the base 1. This, in conjunction with the first gear 12, causes the mounting rod 11 to rotate the mounting frame 3 180 degrees, completing the position conversion of the two sets of mounting boxes 8 and the grinding discs 9 below the mounting boxes 8. The converted grinding discs 9 are aligned with the brush 24. Without affecting the normal operation of the other set of grinding discs 9, the motor inside the fixed frame 7 is activated, causing the cam 23 to rotate and pushing the moving seat 20. The moving seat 20 is fixed... During the sliding process of the rod 21, the spring 22 is squeezed and stretched. In conjunction with the push of the cam 23, the brush 24 vibrates left and right. At the same time, the motor in the moving seat 20 is started to drive the fly disk 27 to rotate. In conjunction with the connecting rod 28, the second rack 26 slides back and forth in the moving seat 20. The second gear 25, which meshes with the second rack 26, drives the brush 24 to sweep back and forth on the surface of the grinding disc 9, cleaning the metal debris stuck to the surface of the grinding disc 9. At the same time, during the vibration of the brush 24 driven by the moving seat 20, the metal debris cleaned by the brush 24 is shaken off to prevent the metal debris from re-adhering to the grinding disc 9.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
