Technical Field

[0001] The present application relates to the technical field of PVD coating fixtures, and in particular to a PVD coating high-efficiency cleaning frame device. Background Art

[0002] PVD coatings are increasingly used in cutting tools, molds, parts, industrial components and other fields due to their excellent wear resistance, low friction, high temperature oxidation resistance, corrosion resistance and other performance characteristics.

[0003] Because PVD is a vacuum coating process, the cleanliness requirements for the workpiece surface are extremely high, free of grease and other contaminants. Ultrasonic cleaning is essential before coating. Conventional ultrasonic cleaning uses a horizontal workpiece cleaning fixture, typically two layers. Manual water jetting is difficult for more layers, the number of clamps is limited, and workpieces with holes on the bottom are difficult to handle.

[0004] When ultrasonically cleaning low-carbon steel workpieces with blind holes, moisture remains in the blind holes, the workpieces are prone to rust, the cleaning quality is unqualified, and the coating quality is affected. At the same time, watermarks remain, affecting the appearance of the coating and failing to meet the quality requirements before coating, which urgently needs to be solved. Utility Model Content

Hooks are respectively fixed to the side walls at both ends of the top and bottom of the square frame. Several slots for clamping the clamping mechanisms are evenly opened on the side of the square frame from top to bottom, and the slots are arranged in an inclined shape.

[0008] The clamping mechanism comprises a sheet-like connecting plate, a plurality of clamping rods for placing workpieces are fixed on the connecting plate at even intervals, and stop blocks are provided at both ends of the connecting plate.

[0009] Preferably, partition rods are rotatably connected to both sides of the top of the square frame.

[0010] By adopting the above technical solution, on the one hand, the partition rod can be used as a handle to facilitate the removal and placement of the cleaning fixture; on the other hand, the cleaning fixture is placed on the cross bar of the cleaning frame, and the partition rod is rotated to a horizontal position, which can serve as a partition between adjacent tooling.

[0011] The cleaning frame includes a bottom frame and two side frames, the two side frames are fixed on the bottom frame, a cross bar is symmetrically fixed between the two side frames, the hook can be matched and clamped in the cross bar, and the hook at the bottom of the square frame can be clamped in the bottom frame.

[0012] A handle is fixed on the side frame.

[0013] Preferably, a screw is threadedly connected to the side frame on one side, and a cushion block is rotatably connected to the end of the screw, and the cushion block can abut against the partition rod.

[0014] By adopting the above technical solution, by rotating the screw, the screw drives the pad to press against the partition rod, and several cleaning fixtures can be tightly pressed and limited on the cleaning frame to ensure the partition effect. During the cleaning and drying process, the cleaning fixture will not swing back and forth in the cleaning frame.

[0015] To sum up, the present application includes at least one of the following beneficial technical effects: the PVD coating high-efficiency cleaning frame device adopts a vertical cleaning fixture to be placed in the cleaning frame to ensure convenient water blowing.

[0019] The following is combined with Figure 1-2 This application is described in further detail.

[0020] The present application discloses a PVD coating high-efficiency cleaning frame device, referring to Figure 1-2, including a cleaning frame 1 and a cleaning fixture 2 installed in the cleaning frame 1, the cleaning fixture 2 can be detachably installed in the cleaning frame 1, the cleaning fixture 2 includes a square frame 21 and several clamping mechanisms 22, and hooks 211 are respectively fixed on the side walls at both ends of the top and bottom of the square frame 21, and a number of slots 212 for clamping the clamping mechanism 22 are evenly opened from top to bottom on the side of the square frame 21, and the slots 212 are arranged in an inclined shape. The clamping mechanism 22 includes a sheet-like connecting plate 221, and a number of clamping rods 222 for placing workpieces are evenly fixed on the connecting plate 221. Stop blocks 2211 are provided at both ends of the connecting plate 221. The setting of the stop block 2211 can limit the connecting plate 221 to prevent it from moving left and right in the square frame 21. The clamping mechanism 22 can be customized according to the type of workpiece.

[0021] The cleaning frame 1 includes a bottom frame and two side frames. The two side frames are fixed on the bottom frame. A cross bar 11 is symmetrically fixed between the two side frames.
