Description

Technical Field

[0001] This utility model relates to the field of PVD coating technology, and in particular to a fixture for PVD coating. Background Technology

[0002] PVD refers to a low-voltage, high-current arc discharge technology used under vacuum conditions. It utilizes gas discharge to evaporate the target material and ionize both the evaporated material and the gas. The electric field then accelerates the evaporation, causing the evaporated material and its reaction products to deposit onto the workpiece. The coating is a solid, continuous film obtained by applying paint in a single coat. It is used for protection, insulation, decoration, and other purposes. PVD coatings are used to improve the surface appearance of workpieces, increase surface strength, and enhance wear resistance, thermal conductivity, corrosion resistance, and scratch resistance. During PVD coating, fixtures are required to fix the workpiece in place.

[0003] Based on the above, the inventors have discovered the following problem: the existing PVD coating fixtures are difficult to fix the inside of the pipe during use, which causes the outside of the pipe to shake easily during coating, affecting the user's use.

[0004] Therefore, it is necessary to provide a fixture for PVD coating to solve the above-mentioned technical problems. Utility Model Content

[0005] This invention provides a fixture for PVD coating, which solves the problems in the background art.

[0006] To solve the above technical problems, this utility model provides a PVD coating fixture, including a device body. An installation platform is movably mounted inside the device body. A support column is mounted at the center of the top surface of the installation platform. A clamping mechanism is mounted on the periphery of the support column. A first installation block, a second installation block, and an extrusion plate are installed inside the clamping mechanism. The second installation block is fixedly connected to the support column. A slide rail is formed on the outer surface of the support column, and a slider is slidably connected inside the slide rail. One end of the first installation block is fixed to the slider. A first mounting seat is mounted on the surface of the first and second installation blocks. A second mounting seat is provided on the surface of the extrusion plate. An adjusting rod is movably mounted between the first and second mounting seats. An extrusion head is provided on the surface of the extrusion plate. A connecting rod is mounted on the bottom surface of the first installation block. The bottom end of the connecting rod passes through the surface of the installation platform and is connected to an arc-shaped threaded plate. A threaded post is connected to the bottom end of the arc-shaped threaded plate. A nut is spirally connected to the outer surface of the threaded post. A limit plate is installed at the top of the nut. By using a combination of support column, clamping mechanism, slide rail, slider, arc-shaped threaded plate, threaded post, nut, and limit plate, it is convenient to clamp and fix the pipe fitting material during coating. During operation, the operator puts the pipe fitting material onto the support column, and then pulls the threaded post downward. The threaded post drives the connecting rod through the arc-shaped threaded plate to pull the first slider downward. Under the action of the first mounting seat, second mounting seat, and adjusting rod, the extrusion plate drives the extrusion head to extrude and fix the inner wall of the pipe fitting. After fixing, the operator rotates the nut, which drives the limit plate upward to abut against the bottom surface of the mounting platform, thus limiting the arc-shaped threaded plate. This method is simple to operate, facilitates the fixing of the pipe fitting material, and improves the stability of coating.

[0007] Preferably, an mounting plate is installed on the outer surface of the device body, and a rotary motor is provided on the bottom surface of the mounting plate. The output end of the rotary motor passes through the surface of the mounting plate and is connected to a rotating platform. A support rod is vertically installed on the top surface of the rotating platform, and the top end of the support rod is fixed to the bottom surface of the mounting platform. By using the rotating platform, support rod, and rotary motor in combination, the rotary motor can be started when processing pipe materials. The rotary motor then drives the rotating platform to rotate, thereby causing the rotating platform to drive the support column to rotate through the support rod and mounting platform, which in turn drives the pipe materials on the surface to rotate. This method is simple to operate and facilitates the improvement of the uniformity of the coating on the pipe materials.

[0008] Preferably, the surface of the second mounting block has a through hole, which facilitates the repositioning of the connecting rod, allowing the connecting rod to drive the first mounting block to slide up and down.

[0009] Preferably, the surface of the mounting platform is provided with an arc-shaped hole, which facilitates the clearance of the arc-shaped threaded plate.

[0010] Preferably, multiple clamping mechanisms are provided, and the multiple clamping mechanisms are installed at equal intervals on the outer surface of the support column. By providing multiple clamping mechanisms, it is convenient to provide stability for the pipe material during clamping.

[0011] Preferably, a fixing plate is provided at the bottom of the device body, and fixing holes are provided on the surface of the fixing plate. By providing the fixing plate, it is easy to fix the device body, thereby providing stability of the equipment during operation.

[0012] Preferably, a controller is installed on the outer surface of the device body, which facilitates the control of the electrical components inside the device body.

[0013] Compared with related technologies, the PVD coating fixture provided by this utility model has the following beneficial effects:

[0014] 1. Compared with existing technologies, this PVD coating fixture, through the coordinated use of a support column, clamping mechanism, slide rail, slider, arc-shaped threaded plate, threaded column, nut, and limiting plate, facilitates the clamping and fixing of pipe fittings during coating. During operation, the operator places the pipe fitting onto the support column, then pulls down the threaded column. This causes the threaded column, through the arc-shaped threaded plate, to drive the connecting rod, pulling the first slider downwards. Under the action of the first mounting seat, second mounting seat, and adjusting rod, the extrusion plate drives the extrusion head to extrude and fix the inner wall of the pipe fitting. After fixing, the work... The operator rotates the nut, causing it to move the limiting plate upwards until it contacts the bottom surface of the mounting platform, thus limiting the arc-shaped threaded plate. This method is simple to operate, facilitates the fixing of pipe fittings, and improves the stability of the coating process. By using a rotating table, support rods, and a rotating motor in conjunction, the rotating motor can be started when processing pipe fittings. The rotating motor then drives the rotating table to rotate, which in turn drives the support column to rotate via the support rods and mounting platform, causing the pipe fittings on the surface to rotate. This method is simple to operate and facilitates the improvement of the uniformity of the coating on the pipe fittings.
