[0029] In the technical solution of this embodiment, through the spherical rotation characteristics of the radial spherical bearing 9 and the stable high load-bearing capacity of the balance spring 10, the grinding jig can be adjusted to be on the same plane as the sanding belt, thereby realizing the parallelism adjustment operation of the grinding jig and facilitating use.

[0030] A fixed frame 3 is provided on the base 1, and several floating needle modules 5 are installed in the fixed frame 3. The floating needle module 55 includes a vertical rod 11, a positioning plate 12 and a spring 17. A plurality of arranged positioning holes 18 are provided on the positioning plate 12. In this embodiment, the positioning holes 18 are staggered in a honeycomb structure. The vertical rod 11 is passed through the positioning hole 18. Part of the vertical rod 11 is located above the positioning hole 18, and part is located below the positioning hole 18. A spring 17 is provided on the outer sleeve of the part of the vertical rod 11 located above the positioning hole 18. When the vertical rod 11 is pressed down, one end of the spring 17 rests on the upper end face of the positioning plate 12 and provides a restoring elastic force to the vertical rod 11.

[0031] Furthermore, a partition 4 may be provided in the fixing frame 3 , and the partition 4 divides the fixing frame 3 into a first area 31 and a second area 32 . A plurality of floating needle modules 5 are provided in the first area 31 and the second area 32 .

[0032] In the technical solution of this embodiment, by placing the product that needs to be ground onto the top of the vertical rod 11, under the action of the product positioning block, the product pushes the vertical rod 11 to move under the action of gravity and shape, and the vertical rod 11 compresses the spring 17 to deform, so that the grinding jig can realize positioning operations on products of different shapes, thereby improving the versatility of the use of the grinding jig.

[0033] A locking module 6 is provided on the front side wall of the fixed frame 3, and the locking module 6 includes a side panel 13. The side panel 13 is fixedly connected to the front side wall of the fixed frame 3. Two push rods 14 are symmetrically threaded on the side panel 13, and a handle 15 is fixedly connected to the front end of the push rod 14.

[0034] In the technical solution of this embodiment, after the product is positioned, the operator rotates the handle 15, the handle 15 drives the top rod 14 to rotate, the top rod 14 pushes the vertical rod 11, and the vertical rods 11 squeeze each other so that the vertical rods 11 cannot return to their original positions under the action of the spring 17, so that the multiple vertical rods 11 pressed down fit the appearance contour of the product, so as to realize the positioning operation of the product and facilitate use.

[0035] Furthermore, a plurality of mounting holes 16 are provided on the side panel 13, and bolts are inserted into the mounting holes 16. The bolts are threadedly connected to the fixing frame 3, so that the side panel 13 can be fixedly installed. A cleaning joint 7 is fixedly connected to the front side wall of the fixing frame 3, and a sewage outlet 8 is provided on the rear side wall of the fixing frame 3.

[0036] In the technical solution of this embodiment, by fixedly connecting the cleaning joint 7 to the external pipeline and injecting the cleaning liquid into the interior of the fixed frame 3 through the cleaning joint 7 through an external device, the cleaning liquid can be used to flush the interior of the fixed frame 3. The cleaning liquid after flushing is discharged through the drain port 8, which facilitates the use of this grinding jig.

[0037] Working principle: when the grinding jig is in use, firstly, the spherical rotation characteristics of the centripetal spherical bearing 9 and the stable high load-bearing capacity of the balance spring 10 are used to adjust the grinding jig to be on the same plane as the sand belt, thereby realizing the parallelism adjustment operation of the grinding jig. Then, the product to be ground is placed on the floating needle module 5. Under the action of the product positioning block, the product is pressed against the vertical rod 11 of the floating needle module 5. The vertical rod 11 compresses the spring 17 and deforms. The vertical rod 11 is pressed down to fit the outer contour of the product, so that the grinding jig can realize the positioning operation of products of different shapes, thereby improving the versatility of the use of the grinding jig. When the product is positioned After that, the operator rotates the handle 15, and the handle 15 drives the top rod 14 to rotate, and the top rod 14 pushes the vertical rod 11. The vertical rods 11 squeeze each other to resist the restoring force of the spring 17, so as to realize the positioning operation of the product, which is convenient for use. At this time, the convenient grinding operation of the product can be realized, and in the process of grinding, by fixing the cleaning joint 7 with the external pipeline and filling the cleaning liquid into the fixed frame 3 through the cleaning joint 7 through the external equipment, the cleaning liquid can be used to flush the inside of the fixed frame 3, and the cleaning liquid after flushing is discharged through the drain port 8, which reduces the influence of impurities on the grinding jig and facilitates the use of the grinding jig.
