[0024] Furthermore, the clamping plate is fixedly connected to the top of the lifting and adjusting screw. The clamping assembly includes a push screw, an L-shaped push seat, and a push block. The clamping plate has an installation cavity. The push screw is located at both ends of the clamping plate. The end of the push screw passes through the edge of the clamping plate and is rotatably connected to the L-shaped push seat. The push block is fixedly connected to the L-shaped push seat.

Both ends of the push screw are provided with locking nuts. The locking nuts are tightened on the inner wall of the installation cavity and the outer wall of the clamping plate, respectively. The push screw controls the push block to be clamped on both sides of the hexagonal nut anti-disengagement sleeve. The clamping plate is fixed to the top of the lifting and adjusting screw, which drives the clamping plate to rotate and lift. The push block is installed on the L-shaped push seat. By loosening the locking nut, the push screw is driven to move the L-shaped push seat and the push block. The push block is limited to both sides of the hexagonal nut anti-disengagement sleeve by the limiting groove, so that the push block is pressed against both sides of the hexagonal nut anti-disengagement sleeve, thereby fixing the hexagonal nut anti-disengagement sleeve in the clamping plate.

The adjustability of the clamping seat and the limiting seat facilitates the center alignment of the nut sleeve and the hexagonal nut anti-loosening sleeve, ensuring that the centers of the nut sleeve and the hexagonal nut anti-loosening sleeve are on the same vertical line, thus improving the assembly accuracy of the nut assembly.
[0026] Furthermore, the top of the adjusting frame is evenly perforated with connecting holes, and the four corners of the clamping platform have through holes corresponding to the adjusting frame.

[0029] Furthermore, the grinding assembly includes an adjusting plate, a grinding machine, a clamping seat, and a push cylinder. An adjusting block is located on one side of the adjusting plate, within an adjusting groove, through which a ball screw passes. A guide block is located on the other side of the adjusting plate, within a guide groove, through which a guide post passes. A drive motor controls the rotation of the ball screw, thereby causing the adjusting plate to rise and fall along the guide post.

Then, the bottom of the lifting frame is connected to the manufacturing table, and the grinding component is installed on the lifting frame. The grinding component is raised and lowered by the lifting frame, so that the grinding component grinds the hexagonal nut anti-loosening sleeve and the nut sleeve clamped on the manufacturing table. Thus, after grinding the end face of the hexagonal nut anti-loosening sleeve, an anti-slip friction texture I is formed, and after grinding the end face of the nut sleeve, an anti-slip friction texture II is formed. Then, the clamping assembly for the nut sleeve is removed from the manufacturing table and then installed in reverse on the manufacturing table, so that the side of the nut sleeve with the second anti-slip friction texture faces the side of the hexagonal nut anti-loosening sleeve with the first anti-slip friction texture. Next, the rotation adjustment assembly on the manufacturing table is driven to control the hexagonal nut anti-loosening sleeve to rotate upwards, thereby controlling the threaded connection between the hexagonal nut anti-loosening sleeve and the nut sleeve, completing the assembly of the nut assembly. Using the manufacturing method of this invention improves the installation accuracy of the nut assembly and avoids collisions between components during assembly, thereby reducing the scrap rate, saving costs, and improving the manufacturing efficiency of the nut assembly.

The bottom of the clamping seat is provided with a slider, which is located in the groove. An adjusting screw is rotatably connected in the groove and passes through the slider. One end of the clamping platform is provided with a screw motor. The output end of the screw motor is connected to the adjusting screw. The screw motor is used to drive the adjusting screw to rotate and drive the clamping seat to slide along the direction of the groove. An L-shaped locking block is fixedly connected to the clamping seat near the center of the clamping platform. Both L-shaped locking blocks are provided with locking grooves corresponding to nuts. The limiting seat is adjustablely connected to the clamping table via a slide rail. The lead screw motor drives the adjusting lead screw to rotate, thereby causing the clamping seat to slide and adjust along the direction of the groove. Through the slots on L-shaped locking blocks one and two, the nut sleeve is clamped between the clamping seat and the limiting seat. The adjustability of the clamping seat and the limiting seat facilitates the center alignment of the nut sleeve and the hexagonal nut anti-loosening sleeve, ensuring that the centers of the nut sleeve and the hexagonal nut anti-loosening sleeve are on the same vertical line, thus improving the assembly accuracy of the nut assembly.
[0033] In this invention, the lifting frame includes a connecting rod, a connecting seat, and a bracket. The connecting seat is fixedly connected to one end of the connecting rod, and the bottom of the bracket is fixedly connected to the connecting seat. Slots are provided on both sides of the bottom of the base, and the other end of the connecting rod passes through these slots. The connecting rod is equipped with a fastening nut, which is tightened onto the base. The connecting seat supports and fixes the bracket.
