However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1, as Figure 1-Figure 5 As shown, the utility model provides a grinding tool for a ball screw thread raceway grinding machine, comprising: two grinding tool bodies 1 and a workbench 17, the top of the workbench 17 is fixedly connected to a column 12, the outer surface of the column 12 is movably connected to a floating tool holder assembly 13, the outer surface of the floating tool holder assembly 13 is symmetrically provided with clamping blocks 11, the tops of the two clamping blocks 11 are each provided with a limiting groove 8, the inner walls of one side of the two limiting grooves 8 are each provided with a sliding groove 6, the inner walls of one side of the two sliding grooves 6 are movably penetrated by a sliding rod 20, one end of the two sliding rods 20 is fixedly connected to a connecting block 5, the other ends of the two sliding rods 20 are fixedly connected to a clamping block 7, the outer surfaces of the two sliding rods 20 are each sleeved with a spring 10, the inner surfaces of the two limiting grooves 8 are movably inserted with a limiting block 2, the outer surfaces of the opposite sides of the two limiting blocks 2 Both are provided with a card slot 3, the inner surfaces of the two card slots 3 are respectively engaged with the outer surfaces of the two card blocks 7, the inner surfaces of the two card blocks 7 are respectively slidably set with the inner surfaces of the two sliding grooves 6, the inner surfaces of the two limit grooves 8 are fixedly connected with support blocks 9 near the bottom, the outer surfaces of the two limit blocks 2 are respectively fixedly connected with the outer surfaces of the two mold bodies 1, and the inner surfaces of the two mold bodies 1 are both provided with threaded protrusions 14. A first power component 16 is provided at the bottom of the workbench 17 near the right side, and a first fixing component 15 is provided on the outer surface of the first power component 16. A second power component 18 is fixedly connected to the bottom of the workbench 17 near the left side, and the driving end of the second power component 18 is fixedly connected to the second fixing component 19. The first fixing component 15 is matched with the column 12.

[0024] The effect achieved by the entire embodiment 1 is that, when the ball screw is being ground, the bottom of the ball screw is placed on the second fixing assembly 19, and then the first power assembly 16 is started to move the first fixing assembly 15 downward to fix the ball screw, and then the two clamping blocks 11 are moved by the floating tool holder assembly 13, so that the two mold bodies 1 are fixed to the ball screw through the movement of the two clamping blocks 11, and the threaded protrusion 14 is fit with the thread groove of the ball screw, and then the second power assembly 18 is started to rotate the ball screw fixed between the first fixing assembly 15 and the second fixing assembly 19, and the rotation of the ball screw and with the cooperation of the column 12 and the floating tool holder assembly 13 drive the clamping block 11 and the mold body 1 to move on the ball screw, and the burrs inside the raceway are removed through the internal threaded protrusion 14, and when the mold body 1 needs to be replaced or disassembled, the connecting block is pulled outward. When the cam 7 is in the closed position, the spring 10 is pressed against the locking cam 11, and the locking cam 7 is pushed out of the closed position and inserted into the locking cam 3, thereby completing the installation of the limit block 2 and the limit groove 8.

[0025] Example 2, as Figure 1-Figure 5 As shown, the outer surfaces of the two connecting blocks 5 are fixedly connected with handles 4.

[0026] The effect achieved by the entire embodiment 2 is that, through the provision of the handle 4, the disassembly of the mold body 1 is made more convenient, further improving the flexibility of the device.

[0027] Working principle: When the mold body 1 needs to be replaced or disassembled, the connecting block 5 is pulled outward by the handle 4, driving the sliding rod 20 to slide on the clamping block 11, so that the clamping block 7 moves to the inside of the sliding groove 6, so that the clamping block 7 and the clamping groove 3 are no longer engaged, and then the mold body 1 is lifted upward to disengage the limit block 2 from the limit groove 8, so that it can be quickly disassembled. When installing, it is only necessary to pull the connecting block 5 to drive the sliding rod 20 to slide on the clamping block 11, so that the clamping block 7 moves to the inside of the sliding groove 6. At this time, the spring 10 will be compressed, and then the limit block 2 will be aligned with the limit groove 8 and pressed downward. When the bottom of the limit block 2 is in contact with the top of the support block 9, the sliding groove 6 will be aligned with the card slot 3, and then the connecting block 5 will be released. As a result, under the restoring force of the spring 10, the card block 7 will be pushed out of the sliding groove 6 and inserted into the card slot 3, completing the limit installation of the limit block 2 and the limit groove 8, thereby quickly installing the mold body 1, making it convenient to maintain and replace the mold body 1 and improving the practicality of the device.

The model is selected according to the actual use, so the control method and wiring arrangement of the first power assembly 16 and the second power assembly 18 are not explained in detail.
