The front end of the fixing frame 41 is fixedly connected to a fixing plate 53. The inner front end of the fixing plate 53 is evenly provided with sliding grooves 531. The interior of a plurality of the sliding grooves 531 is movably connected to a second spring 532. The interior of the sliding grooves 531 is movably connected to a slider 541. The slider 541 is located at the front end of the second spring 532. The front ends of a plurality of the sliders 541 are movably connected to the slider 541. The elastic force of the first spring 523 is greater than the force exerted on the locking block 54 by the push block 521, and the elastic force of the second spring 532 is greater than the force exerted on the locking block 54.

[0028] By adopting the above technical solution, when the annular parts need to be vacuum coated, the parts are inserted into the outer middle end of the locking block 54 and fixed. After all the parts to be coated are fixed, the sliding door 21 outside the cylinder 2 is opened, and the upper components and parts of the turntable 11 are placed inside the cylinder 2. After confirming that the turntable 11 is fixed to the upper end of the motor 3, the sliding door 21 is closed. At this time, the motor 3 inside the bottom plate 1 is started, and the output shaft of the motor 3 rotates, so that the output shaft of the motor 3 rotates and drives the turntable 11 to rotate. The turntable 11 rotates The rotating shaft 4 at the upper end of the rotating disk 11 rotates, and the rotation of the rotating shaft 4 drives the fixed frame 41 outside the rotating shaft 4 to make a circular motion with the rotating shaft 4 as the axis. At this time, the counterweight block 522 inside the movable chamber 51 is affected by the centrifugal force generated by the rotation of the fixed frame 41, and moves toward the front end of the movable chamber 51. The counterweight block 522 moves forward, driving the push block 521 at the front end of the connecting rod 52 to move forward. The push block 521 moves forward and pushes the rear end of the slider 541, so that each slider 541 moves outward along the slide groove 531. The slider 541 moves outward with The locking blocks 54 move outwards, and each locking block 54 moves outwards to reduce the distance between the locking blocks 54 and the parts, so that during the coating process, the locking blocks 54 are rotated and displaced to clamp and fix the parts, so that the parts remain stable and not easy to fall off during the coating process, so as to achieve the effect of preventing the parts from loosening during the coating process. After the vacuum coating, the turntable 11 stops rotating with the rotating shaft 4 and the fixing frame 41, and the turntable 11 and the upper end parts are taken out through the sliding door 21. At this time, the counterweight block 522 in the active chamber 51 Without being affected by the centrifugal force, it returns to its original position under the influence of the elastic force of the first spring 523. The counterweight block 522 moves backward with the connecting rod 52. At this time, the connecting rod 52 moves backward with the push block 521. The slider 541 returns to its original position without being pushed by the slider 541 and is affected by the second spring 532. The slider 541 then returns to its original position with the locking block 54. The gap between the locking block 54 and the parts increases. At this time, the parts are released to solve the problem of loosening and uneven coating of the coated parts during rotation.

[0029] Specifically, Figure 4As shown, the upper and lower ends of the fixed frame 41 are both provided with a padlock assembly 6, and the padlock assembly 6 includes a fixed frame 41 fixedly connected to the upper and lower ends of a movable cylinder 61, a plurality of rollers 63 are movably connected inside the movable cylinder 61, a rotating rod 62 is fixedly connected inside the movable cylinder 61, and the rotating rod 62 passes through each roller 63, a plurality of torsion springs 621 are fixedly connected outside the rotating rod 62, a chuck 622 is movably connected outside the rotating rod 62, the chuck 622 is located at the rear end of the torsion spring 621, and the rear end of the chuck 622 is movably connected to a third spring Spring 623, multiple hooks 64 are evenly distributed on the outer lower end of the movable cylinder 61, and connecting ropes are fixedly connected between the multiple hooks 64 and the rotating rods 62 in each roller 63, and the connecting rope is located between the torsion spring 621 and the chuck 622, the elastic force of the torsion spring 621 is greater than the gravity exerted on the pull rope and the hook 64, the elastic force of the third spring 623 is greater than the force exerted on the chuck 622, a groove is provided at the front end of the chuck 622, and the width of the groove is greater than the width of the torsion spring 621, and the length of the pull rope outside the rotating rod 62 is greater than the distance between the fixed frames 41.

[0030] By adopting the above technical solution, the hook 64 at the outer end of the movable cylinder 61 is pulled out through the inside of the roller 63, and the rotating rod 62 is rotated to tighten the torsion spring 621, and the parts of different lengths are fixed by the hook 64, and then the turntable 11 and the upper end parts are sent into the cylinder body 2 through the sliding door 21. At this time, the motor 3 inside the bottom plate 1 is started, and the output shaft of the motor 3 rotates, so that the output shaft of the motor 3 rotates with the turntable 11 and the upper end components. At this time, the chuck 622 inside the roller 63 is affected by the centrifugal force and moves toward the outer end of the movable cylinder 61, so that the groove at the outer end of the chuck 622 clamps the torsion spring 621 to prevent the torsion spring 62 from 1 is moved, so that when the parts of different specifications are rotated, the chuck 622 can fix the rotating rod 62, so that the parts will not move and vibrate during the rotary coating process. After the vacuum coating, the turntable 11 stops rotating with the rotating shaft 4 and the fixing frame 41. At this time, the chuck 622 is not affected by the centrifugal force and is affected by the elastic force of the third spring 623, so that the chuck 622 moves to the rear end and returns to the initial position, and then the parts are taken out through the hook 64, so as to solve the problem of fixing the parts of different specifications, further avoid the movement and vibration of the parts during the rotary coating process, thereby improving the coating quality.

[0031] Working principle: When the annular parts need to be vacuum coated, the parts are inserted into the outer middle end of the locking block 54 and fixed. After all the parts to be coated are fixed, the sliding door 21 outside the cylinder 2 is opened, and the upper parts and parts of the turntable 11 are placed into the cylinder 2. After confirming that the turntable 11 is fixed to the upper end of the motor 3, the sliding door 21 is closed. At this time, the motor 3 inside the bottom plate 1 is started, and the output shaft of the motor 3 rotates, so that the output shaft of the motor 3 rotates with the turntable 11, and the rotation of the turntable 11 rotates the shaft 4 at the upper end of the turntable 11, and the rotation of the shaft 4 drives the shaft 4 The external fixing frame 41 makes a circular motion with the rotating shaft 4 as the axis. At this time, the counterweight block 522 inside the movable chamber 51 is affected by the centrifugal force generated by the rotation of the fixing frame 41 and moves toward the front end of the movable chamber 51. The counterweight block 522 moves forward, driving the push block 521 at the front end of the connecting rod 52 to move forward. The push block 521 moves forward and pushes the rear end of the slider 541, so that each slider 541 moves outward along the slide groove 531. The slider 541 moves outward and drives the locking block 54 outward. The outward movement of each locking block 54 reduces the distance between the locking block 54 and the gap between the parts to achieve a locking effect.
