Detailed Implementation

[0019] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] like Figures 1-5As shown, a workpiece positioning mechanism for vacuum coating of hardware includes a base 1 and an annular plate 2 mounted on the top of the base 1 by multiple support rods. A rotating table 3 is rotatably connected inside the annular plate 2. The top of the rotating table 3 has multiple slots 4. Each slot 4 contains a first fixing mechanism and a second fixing mechanism that works in conjunction with the first fixing mechanism. The first fixing mechanism includes a connecting plate 12 located inside the slot 4, support plates 15 on both sides of the connecting plate 12, a first positioning block 18 mounted on the top of the support plate 15, and a driving mechanism inside the connecting plate 12 for moving the two first positioning blocks 18. The second fixing mechanism includes two support plates 23 located inside the slot 4, and a second fixing mechanism mounted on the side of the two support plates 23 that is close to each other. Positioning block 24, two first positioning blocks 18 are located between two second positioning blocks 24, and the distance between the two second positioning blocks 24 and the connecting plate 12 is the same, and the two first positioning blocks 18 and the two second positioning blocks 24 are on the same horizontal line. The two second positioning blocks 24 are higher than the two first positioning blocks 18. The bottom of the rotary table 3 is provided with a moving mechanism that drives the two second positioning blocks 24 to move closer to or further away from the connecting plate 12. The top of the base 1 is provided with a lifting mechanism that drives the first fixing mechanism to lift. The inside of the strip-shaped opening 4 is equipped with a limiting rod 21. The support plate 23 is sleeved on the outside of the limiting rod 21. The limiting rod 21 can limit the support plate 23 so that the moving mechanism can maintain a linear motion state when pushing the support plate 23 to move.

[0021] The drive mechanism includes a mounting cavity 16 opened in the connecting plate 12, two movable blocks 14 slidably connected inside the mounting cavity, and a fixed rod 17 installed on the side of the two movable blocks 14 that is far away from each other. One end of each fixed rod 17 extends to the outside of the connecting plate 12 and is fixedly connected to one side of the two first positioning blocks 18 respectively. A spring 19 is sleeved on the outside of the fixed rod 17 and is fixedly connected to the inner wall of the mounting cavity 16 and one side of the movable block 14.

[0022] The moving mechanism includes a mounting plate 25 and a push plate 13 located at the center of the bottom of the rotary table 3, as well as push rods 22 movably connected to both sides of the mounting plate 25. One end of each push rod 22 is movably connected to one side of each of the two support plates 23. A connecting rod 26 fixed to the outside of the push plate 13 is installed at the bottom of the mounting plate 25. A first electric telescopic rod 6 is installed at the top of the base 1. The output end of the first electric telescopic rod 6 is rotatably connected to the bottom of the push plate 13 through a bearing. A moving groove 20 is provided on the connecting plate 12 to facilitate the movement of the mounting plate 25.

[0023] When metal parts need to be coated, push the two support plates 15 to one side of the connecting plate 12 to place the annular metal parts to be coated on the outside of the connecting plate 12 and on top of the two support plates 15. After releasing the support plates 15, under the action of the spring 19, the two first positioning blocks 18 can fix the annular metal parts from the inner wall, and the bottom of the support plates 15 will lift the metal parts. When the metal parts are fixed on the outside of multiple first fixing mechanisms, the lifting mechanism will drive the first fixing mechanisms to move upward, so that the bottom of the metal parts is separated from the top surface of the base 1, and then the coating work is carried out. After coating for a period of time, the first electric telescopic rod 6 will drive the connecting rod 2. 6. The mounting plate 25 moves downward under the drive of the connecting rod 26, which in turn moves the two push rods 22. Under the drive of the two push rods 22, the two support plates 23 move towards each other, which in turn moves the two first positioning blocks 24 towards each other, thus fixing the ring-shaped hardware from the outside. Then the lifting mechanism moves the first fixing mechanism downward, thereby separating the support plate 15 and the first positioning block 18 from the hardware, so that the shielding area of ​​the first fixing mechanism can be coated. At this time, it is not necessary to disassemble and reinstall the hardware. The shielding area can be coated directly, thereby improving the processing efficiency of the hardware.

[0024] like Figure 3 As shown, the lifting mechanism includes a movable platform 5 and two second electric telescopic rods 9 mounted on the top of the base 1. The movable platform 5 has a ring structure, and the output end of the first electric telescopic rod 6 passes through the movable platform 5. The bottom of the connecting plate 12 is fixedly connected to the top of the movable platform 5. An annular groove 10 is provided at the bottom of the movable platform 5, and a slider 11 is slidably connected inside the annular groove 10. The bottom of the slider 11 is fixedly connected to the output end of the second electric telescopic rod 9. When the annular hardware is fixed on the first fixing mechanism, the second electric telescopic rod 9 will drive the movable platform 5 to move upward. When the movable platform 5 moves upward, it will drive multiple connecting plates 12 to move upward, thereby... The two first positioning blocks 18 and two support plates 15 set on the connecting plate 12 will move upward, thereby moving the hardware upward, so that the bottom of the hardware will separate from the top surface of the rotating table 3. When the hardware moves up between the two second positioning blocks 24, the second electric telescopic rod 9 stops moving, so that the two second positioning blocks 24 can fix the hardware. After the second fixing mechanism fixes the hardware from the outside, the second electric telescopic rod 9 will move the moving table 5 downward, thereby moving the connecting plate 12 downward, and then moving the first fixing mechanism downward, so that the support plate 15 and the first positioning block 18 will separate from the hardware.

[0025] like Figure 3As shown, a rotary motor is installed at the bottom of the annular plate 2, and a drive wheel 8 is installed at the output end of the rotary motor. A driven wheel 7 that meshes with the drive wheel 8 is installed on the outside of the rotary table 3. During the coating process, the rotary motor drives the drive wheel 8 to rotate. With the cooperation of the drive wheel 8 and the driven wheel 7, the rotary table 3 will rotate, which will in turn drive multiple hardware parts fixed on the top of the rotary table 3 to rotate, thereby enabling better coating of the hardware parts.

[0026] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
