Description
Technical Field
[0001] This utility model relates to the field of coating performance testing technology, and in particular to a device for testing the coating performance of injection molded machine parts. Background Technology

[0003] The utility model patent with publication number CN219475268U discloses a metal surface metal coating wear resistance testing device. "Through the forward and reverse rotation of the bidirectional threaded rod, two clamping plates can be driven to slide closer or further apart inside two sliding grooves. The spacing can be quickly adjusted and fixed according to the size of the metal part, which effectively improves the testing range of the metal coating wear resistance testing device and saves the cost of metal part coating wear resistance testing equipment." Although it solves the problem of "different metal products have different sizes and the clamping range is limited", existing coating testing devices are mostly single-sided testing structures, which can only test the coating on the top of the fixed part. If the coating on the bottom of the mechanical part also needs to be tested, it is necessary to disassemble, flip or adjust the position of the part, which prolongs the testing process. Therefore, a coating performance testing device for injection molded mechanical parts is proposed. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present invention provides a solution to the problem that if the coating on the bottom of the mechanical parts needs to be tested, the parts need to be disassembled, flipped, or their positions adjusted.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention. Example
[0032] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A coating performance testing device for injection molded mechanical parts includes an equipment frame 1, a mounting frame 2 fixedly connected to the top of the equipment frame 1, and a wear resistance testing device 3 mounted on the surface of the mounting frame 2 (which is prior art and will not be described in detail). The inner cavity of the equipment frame 1 is provided with a flipping frame 4, which is U-shaped to facilitate the mounting of mechanical parts. Rotating rods 5 are fixedly connected to both sides of the flipping frame 4, so that the flipping frame 4 can rotate to facilitate the subsequent flipping of the mechanical parts.
[0033] Two support plates 6 are L-shaped and symmetrically distributed. The two support plates 6 are placed inside the flipping frame 4. A connecting block 8 is fixedly connected to one end of the support plate 6. A moving hole 9 is opened in the middle of one side wall of the flipping frame 4 to provide sliding space for the connecting block 8. A driving component 7 is provided on one side of the equipment frame 1, and a size adjustment component 10 is provided on one side of the flipping frame 4. A fixing component 11 is provided on the top of the support plate 6. One end of the rotating rod 5 is rotatably connected to the inner wall of the equipment frame 1, and one end of the other rotating rod 5 rotates through the inner wall of the equipment frame 1 and extends to the outside. The connecting block 8 is slidably connected to the inner cavity of the moving hole 9.
[0034] Preferably, the drive component 7 includes a mounting plate 71 fixed to one side wall of the equipment frame 1. The mounting plate 71 has a U-shaped design. A drive unit 72 is installed on one side wall of the mounting plate 71. The drive unit 72 is specifically a cylinder. The rotation of the mechanical parts provides power. The output end of the drive unit 72 slides through one side of the surface of the mounting plate 71 and is connected to a toothed plate 73. One end of the toothed plate 73 is fixedly connected to a limit strip 74, which limits the toothed plate 73. One end of the limit strip 74 slides through the other side of the surface of the mounting plate 71. One end of another rotating rod 5 is fixedly connected to a gear 75, which meshes with the toothed plate 73.
[0035] Preferably, the size adjustment component 10 includes fixing blocks 101 fixed to both sides of one side wall of the flipping frame 4, and a bidirectional threaded rod 102 rotatably connected between the two fixing blocks 101. The two ends of the bidirectional threaded rod 102 are distributed with two opposite threads. When it rotates, the two support plates 6 move relative to each other or away from each other through the connecting block 8. The two ends of the bidirectional threaded rod 102 are respectively threadedly connected to the two connecting blocks 8, and a gripping block 103 is fixedly connected to the middle of the bidirectional threaded rod 102.
[0036] Preferably, the fixing member 11 includes a protrusion 111 fixedly connected to the top inner side of the support plate 6. A screw 112 is threadedly connected to the surface of the protrusion 111. The pressure plate 113 is driven to rise and fall by rotation. The bottom end of the screw 112 is rotatably connected to the pressure plate 113 to press the parts and prevent slippage during testing. The pressure plate 113 is slidably connected to the inner wall of the support plate 6. A knob 114 is fixedly connected to the top end of the screw 112.
[0037] The usage process of the coating performance testing device for injection molded mechanical parts provided by this utility model is as follows: First, when installing the mechanical parts, the operator rotates the grip block 103 by hand according to the size of the mechanical parts, so that the bidirectional threaded rod 102 rotates. At the same time as the bidirectional threaded rod 102 rotates, the two connecting blocks 8 drive the two support plates 6 to move relative to each other or in opposite directions until the size of the mechanical parts is met. Then, the mechanical parts are inserted from one side of the flipping frame 4 between the pressure plate 113 and the support plate 6. Then, the operator rotates the two knobs 114 in sequence to move the two pressure plates 113 downward to fix the mechanical parts. After completion, the wear resistance testing device 3 can be started to move its detection head downward to test the coating on the top surface of the mechanical parts. If it is necessary to test the bottom surface of the mechanical parts, the drive unit 72 can be controlled to move the toothed plate 73 to one side under the limiting action of the limiting strip 74, and cooperate with the gear 75 to make the flipping frame 4 drive the mechanical parts to rotate 180 degrees, thereby realizing the double-sided testing of the mechanical parts.
