Description

Technical Field

[0001] This utility model relates to the field of PVD coating fixture technology, specifically an adjustable PVD coating fixture. Background Technology

[0002] PVD coating fixtures are mainly used to fix and support the workpiece being coated, ensuring that it maintains the correct position and orientation during the coating process. The workpiece needs uniform and high-quality coating, which is why PVB coating fixtures can make the workpiece move uniformly to ensure the uniformity of the coating. Currently, the holes of the workpiece often need to be fixed with fixtures during the coating process. However, traditional PVD coating fixtures are difficult to adapt to workpieces with different hole sizes, requiring frequent fixture changes, which greatly reduces the efficiency and stability of workpiece coating. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an adjustable PVD coating fixture.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] An adjustable PVD coating fixture, comprising:

[0006] The control panel is cylindrical.

[0007] An adjustable limiting assembly is installed on the top of the operating table. The adjustable limiting assembly includes a fixed column, a positioning column, and five sets of limiting plates. The positioning column is installed at the center of the upper surface of the fixed column. Five sets of through holes are provided on both sides of the positioning column. A sliding rod is provided between each of the five sets of limiting plates and the five sets of through holes. The sliding rod slides in the through holes. A compression spring is provided on the surface of the sliding rod. One end of the compression spring is connected to the limiting plate, and the other end of the compression spring is connected to the positioning column. The hole of the workpiece is installed on the positioning column. The compression spring is used to make the limiting plate abut against the inside of the hole of the workpiece to fix the workpiece.

[0008] Preferably, a guide plate is provided on the upper side of the limiting plate. The guide plate is an arc-shaped plate. The guide plate is bent towards the positioning post to guide the hole of the workpiece to be engaged with the limiting plate, thereby ensuring that workpieces with different hole sizes can be engaged and limited by the limiting plate, and ensuring the stability of the workpiece during coating.

[0009] Preferably, a clamp rotation assembly is installed inside the operating table. The clamp rotation assembly includes a rotary motor, a rotating shaft, a main gear, and four sets of secondary gears. The rotary motor is installed at the bottom of the operating table. The rotary motor drives the main gear to rotate through the rotating shaft, and the main gear drives the four sets of secondary gears to rotate.

[0010] Preferably, a toothed disc is provided on the outer side of the secondary gear. The toothed disc is circular and mounted on the upper side of the operating table. The secondary gear meshes with the toothed disc. An adjustable limiting component is mounted on the upper surface of each set of secondary gears. The fixed column is installed at the center of the secondary gear. The secondary gear rotates around the toothed disc, thereby driving the adjustable limiting component to revolve and rotate, so that the workpiece can rotate evenly and ensure that the target material can be deposited evenly on the surface of the workpiece.

[0011] Preferably, the upper surface of the fixing column is provided with 5 sets of sliding grooves, and the 5 sets of sliding grooves are respectively placed directly below the 5 sets of limiting plates. A sliding column is provided below the limiting plate, and the sliding column slides in the sliding groove to fix the lower part of the limiting plate, so as to prevent the limiting plate from deforming when fixing the workpiece and affecting the fixing effect of the workpiece.

[0012] Beneficial effects: In the adjustable PVD coating fixture of this utility model, the rotary motor drives the secondary gear to rotate around the gear disk through the main gear, thereby driving the adjustable limiting component to revolve and rotate, so that the workpiece can rotate evenly and ensure that the target material can be deposited evenly on the surface of the workpiece. The compression spring in the adjustable limiting component causes the limiting plate to abut against the inside of the hole of the workpiece to fix the workpiece. The sliding column slides in the sliding groove to fix the lower part of the limiting plate, so as to avoid the limiting plate from deforming when fixing the workpiece and affecting the fixing effect of the workpiece.

A sliding rod 13 is provided between the five sets of limiting plates 8 and the five sets of through holes 14. The sliding rod 13 slides in the through holes 14. A compression spring 12 is provided on the surface of the sliding rod 13. One end of the compression spring 12 is connected to the limiting plate 8, and the other end of the compression spring 12 is connected to the positioning post 15. The hole of the workpiece is installed on the positioning post 15. The compression spring 12 is used to make the limiting plate 8 abut against the inside of the hole of the workpiece to fix the workpiece.

[0023] In an embodiment, such as Figure 3 As shown, a guide plate 9 is provided on the upper side of the limiting plate 8. The guide plate 9 is an arc-shaped plate. The guide plate 9 bends toward the positioning post 15 to guide the workpiece hole to be engaged with the limiting plate 8, thereby ensuring that workpieces with different hole sizes can be engaged and limited by the limiting plate 8, and ensuring the stability of the workpiece during coating.

[0024] In an embodiment, such as Figure 2 As shown, a clamp rotation assembly is installed inside the operating table 1. The clamp rotation assembly includes a rotary motor 6, a rotating shaft 7, a main gear 5, and four sets of secondary gears 4. The rotary motor is installed at the bottom of the operating table 1. The rotary motor 6 drives the main gear 5 to rotate through the rotating shaft 7. The main gear 5 drives the four sets of secondary gears 4 to rotate.

[0025] In an embodiment, such as Figure 2As shown, a toothed disc 2 is provided on the outer side of the secondary gear 4. The toothed disc 2 is circular and installed on the upper side of the operating table 1. The secondary gear 4 meshes with the toothed disc 2. An adjustable limiting component is installed on the upper surface of each set of secondary gears 4. The fixed column 3 is installed at the center of the secondary gear 4.
