During the movement of the fixed frame 201a, the L-shaped rod 409 can be driven to move, and through the movement of the L-shaped rod 409, the pulley 410 can be used to apply a force to the circular groove 411 to adjust the position of the grinding ring 200d.

[0045] Example 3

[0046] Reference Figures 1 to 3 , which is the third embodiment of the present invention, provides a flipping mechanism 300 to achieve double-sided grinding of parts.

[0047] The flip mechanism 300 is arranged on the top of the machine body 100. The flip mechanism 300 includes two flip assemblies 301. The two flip assemblies 301 are respectively arranged on the left and right sides of the grinding table 102. The flip assembly 301 includes a support frame 301a. The interior of the support frame 301a is hollow. The inner wall of the support frame 301a is provided with an annular groove 301b. The surface of the annular groove 301b is slidably connected with a sliding column 301c. The right side of the sliding column 301c is rotatably connected with a second gear 301d. The surface of the second gear 301d is meshed with teeth 301e. The teeth 301e are provided with a plurality of teeth and are evenly distributed on the inner wall of the support frame 301a. The surface of the sliding column 301c is sleeved with a connecting rod 301f. The left and right sides of the connecting rod 301f are penetrated by connecting columns 301c. 1g, the left side of the connecting column 301g is fixedly installed with the outer surface of the support ring 200b, and the right side of the second gear 301d is provided with a clamping component 302, and the clamping component 302 includes an electric push rod 302a, and the right side of the electric push rod 302a extends to the right side of the support frame 301a, and the right side of the electric push rod 302a is fixedly installed with a clamping plate 302b, and the right side of the clamping plate 302b is provided with a wrapping pad 302c, and the two ends of the left side of the wrapping pad 302c are fixedly installed with a cross bar 302d, and the left side of the cross bar 302d extends to the left side of the clamping plate 302b, and the left side of the cross bar 302d is provided with a limiting ring 302e, and the surface of the cross bar 302d is provided with a spring 302f, and the left and right sides of the spring 302f are fixedly installed with the right side of the limiting ring 302e and the left side of the clamping plate 302b.

[0048] Specifically, during grinding, the part can be first clamped by the clamping component 302 , and then flipped by the flipping assembly 301 .

[0049] Furthermore, when the other side needs to be polished, the connecting column 301g can be used to drive the connecting rod 301f to move upward through the upward movement of the electric cylinder 103, and the upward movement of the connecting rod 301f can drive the sliding column 301c to move on the surface of the annular groove 301b, and when the sliding column 301c moves, the second gear 301d can be meshed with the tooth 301e. Since the second gear 301d will rotate when it moves again after meshing with the tooth 301e, it can drive the electric push rod 302a to rotate to complete the flipping.

[0050] It should be noted that the top and bottom of the annular groove 301b are both configured to be inclined, so as to provide a moving path for the sliding column 301c.

[0051] The remaining structure is the same as that of Example 2.

[0052] Example 4

[0053] Reference Figures 1 to 6 , which is the fourth embodiment of the present invention. This embodiment is different from the third embodiment in that: this embodiment provides a positioning device for processing small mechanical parts.

[0054] When it is necessary to grind the parts, the operation of the electric push rod 302a can drive the clamping plate 302b to wrap the surface of the parts with the wrapping pad 302c. After the wrapping pad 302c is squeezed, the cross bar 302d can be driven to move in the opposite direction and pull the spring 302f. During the movement of the cross bar 302d, the telescopic rod 404 can be driven to move, and the movement of the telescopic rod 404 can drive the matching rod 403 to move. During the movement of the matching rod 403, the pulling rod 202d can be driven to move at the same time, so that it exerts pressure on the squeezing plate 202a through the pulling rod 202d. The torsion spring 202b is used to apply a pulling force to the extrusion plate 202a, and the pulling force applied to the extrusion plate 202a is used to apply a torsion force to the torsion spring 202b, so that the extrusion plate 202a applies an extrusion force to the first tooth plate 201b-1, so that the first tooth plate 201b-1 and the first gear 201c are released from the meshing relationship. Then, the torsion force release of the torsion spring 202b can drive the fixed frame 201a to move on the surface of the support groove 201e by using the support rod 201f. During the movement of the fixed frame 201a, the L-shaped rod 409 can be driven to move. Through the movement of the L-shaped rod 409, the pulley 410 can be used to apply a giving force to the circular groove 411 to adjust the position of the grinding ring 200d.

[0055] When the other side needs to be polished, the connecting column 301g can be used to drive the connecting rod 301f to move upward through the upward movement of the electric cylinder 103, and the upward movement of the connecting rod 301f can drive the sliding column 301c to move on the surface of the annular groove 301b. When the sliding column 301c moves, the second gear 301d can be meshed with the tooth 301e. Since the second gear 301d will rotate when it moves again after meshing with the tooth 301e, it can drive the electric push rod 302a to rotate to complete the flipping.

[0056] In summary: by setting the adjustment component 201, the position of the grinding ring 200d can be adjusted according to the size of the mechanical part, and by setting the flipping mechanism 300, the part can be flipped to grind the other side.
