[0029] The side of the clamping plate 17 is connected to the square plate 18, and a second threaded pressure rod 21 is provided inside the square plate 18. A square groove 25 and an arc groove 24 are provided on the inner side of the clamping plate 22. The sleeve 15 is installed inside the frame 14, and the insertion rod 16 is embedded inside the sleeve 15. The square plate 18 is embedded inside the square groove 25. A second threaded pressure rod 21 is provided inside the arc groove 24, and a rubber plate 23 is embedded outside the frame 14. By installing the clamping plate 22, the arc groove 24, the square groove 25, and the insertion rod 16 on the outside of the frame 14, it is convenient to replace the damaged rubber plate 23, and it is more convenient to install and disassemble.

[0030] The side of the fixing seat 5 is fixedly connected to the side plate 7, a circular hole 8 is provided on the outside of the side plate 7, a guide rod 10 is embedded in the circular hole 8, the bottom of the guide rod 10 is fixedly connected to the fixing block 12, and the fixing block 12 is fixedly connected to the frame 14. Since the side plate 7 is installed, it is convenient to connect the guide rod 10 to the fixing seat 5.

[0031] A slide groove 3 is provided on the top of the bottom plate 1 , a slider 4 is fixedly connected to the bottom of the frame 14 , and the slider 4 is embedded inside the slide groove 3 . Due to the installation of the slider 4 and the slide groove 3 , the frame 14 can be quickly moved on the top of the bottom plate 1 .

[0032] A groove 19 is formed inside the square plate 18 , and the groove 19 is fixedly connected to the second turntable 20 . The outside of the second turntable 20 is fixedly connected to the second threaded pressure rod 21 . The square plate 18 and the groove 19 facilitate the installation of the second turntable 20 on the outside of the clamping plate 17 .

[0033] The top is provided with a mounting hole 2, the side of the frame body 14 is fixedly connected to the ring body 13, and the inside of the ring body 13 is provided with a second threaded pressure rod 21. Due to the provision of the mounting hole 2, the bottom plate 1 is conveniently installed and fixed in position.

[0034] The working principle of the workpiece clamping fixture for the grinding machine is as follows: when using the clamping fixture, it is first necessary to install it at the designated position, and then the user holds the base plate 1 to pick it up and transfer it. After moving to the designated position, the base plate 1 is placed on the plane, and the fastener is taken to pass it through the mounting hole 2 to fix its position with the plane. Secondly, a fixing seat 5 is installed on the top of the base plate 1, and at the same time, a side plate 7 is connected to the side of the fixing seat 5, and a first threaded pressure rod 9 is connected to the inside of the fixing seat 5. Secondly, a guide rod 10 is embedded in the inside of the side plate 7. Then, in order to facilitate the clamping of clamps of different shapes, different clamping structures are installed. By installing a first turntable 11 at the bottom of the first threaded rod, and installing a fixing block 12 at the bottom of the guide rod 10, the first turntable 11 and the fixing block 12 are connected to the outside of the frame 14. Secondly, a clamping plate 17 is provided inside the frame 14. When circular clamps of different specifications need to be clamped, only the second screw on the outside of the clamping plate 17 needs to be turned. The threaded pressure rod 21 will not drive the clamping plate 17 to rotate due to the installation of the square plate 18 and the second rotating disk 20. When the square clamp needs to be clamped, it is only necessary to insert the insertion rod 16 on the back of the clamping plate 22 into the sleeve 15 inside the frame body 14, and a rubber plate 23 is provided on the outside. When the square clamp to be clamped is small, it is only necessary to screw the first threaded pressure rod 9 to drive the frame body 14 at the top of the slider 4 to move inward, so that not only clamps of different shapes can be clamped, but also clamps of different sizes can be clamped, so it is more convenient to use. Secondly, when the clamping plate 22 is worn out due to long-term use, the insertion rod 16 on the back of the clamping plate 22 is first pulled out from the inside of the sleeve 15, and at the same time, the square groove 25 and the arc groove 24 are pulled out from the outside of the square plate 18 and the second threaded pressure rod 21, and then a new clamping plate 22 structure is taken out for replacement, so that the severely worn rubber plate 23 can be replaced, and it is more convenient to install and disassemble.
