Description

Technical Field

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

[0002] Spraying can form a protective film on the surface of a workpiece, preventing the metal from being corroded by the external environment and ensuring the appearance of the workpiece. Spraying fixtures are special tools used to fix, support or protect the workpiece during the spraying process, ensuring uniform and efficient spraying.

[0003] In existing technologies, when a conventional spraying fixture fixes a workpiece, the relatively large contact area between the clamping part and the workpiece surface directly results in these contact areas not being effectively covered by paint. The contact surface between the fixture and the workpiece forms a physical barrier, preventing the paint sprayed from the spray gun from reaching these areas, thus creating unpainted exposed parts on the workpiece surface. The existence of these unpainted areas directly affects the appearance quality and protective performance of the product. To ensure the integrity and uniformity of the overall coating on the workpiece, secondary processing of these unpainted areas is usually required, which seriously affects work efficiency. Therefore, it is necessary to improve the spraying fixture for sprayed parts to solve the above problems. Utility Model Content

[0004] To overcome the problem that the contact area between the clamping component and the workpiece is too large, resulting in the contact surface being unable to be sprayed, thus creating exposed areas that require secondary processing.

[0005] The technical solution of this utility model is as follows: a spraying fixture for sprayed parts, including a limiting cylinder and a baffle slidably connected to the limiting cylinder. An adjustment component for flipping angle is fixedly connected to the limiting cylinder. A positioning component for fixing a position is provided on the adjustment component. An installation block is fixedly connected to one side of the baffle. An elastic plate is fixedly connected to the side of the installation block away from the baffle. A ejector pin is fixedly connected to the elastic plate. The ejector pin is positioned to hold the workpiece by the elasticity of the elastic plate.

[0006] Preferably, there are two baffles, and the limiting cylinder has matching grooves at corresponding positions of the two baffles. The two baffles slide inside the corresponding grooves respectively, and the two baffles are staggered and fit together.

[0007] Preferably, a first rotating block is rotatably connected to the limiting cylinder, and a bidirectional threaded rod is fixedly connected to one end of the first rotating block. A sliding plate is threadedly connected to the bidirectional threaded rod, and the sliding plate is fixedly connected to the side of the baffle away from the mounting block. A first unidirectional threaded rod is rotatably connected to the elastic plate, and a limiting plate for adjusting the opening angle of the elastic plate is threadedly connected to the first unidirectional threaded rod. A first nut is threadedly connected to the first unidirectional threaded rod, and a second nut is threadedly connected to the first unidirectional threaded rod. The first nut and the second nut cooperate to position the limiting plate.

[0008] Preferably, the limiting plate has a through groove, and the elastic plate passes through the through groove.

[0009] Preferably, the adjusting assembly includes a positioning shell fixedly connected to the limiting cylinder, a worm gear rotatably connected to the positioning shell, a second rotating block fixedly connected to one end of the worm gear, a worm wheel meshing on the worm gear, a rotating shaft fixedly connected to the worm wheel, and the rotating shaft rotatably connected to the positioning shell.

[0010] Preferably, the positioning component includes a first clamping plate fixedly connected to one end of the rotating shaft, a second one-way screw rotatably connected to the first clamping plate, a second clamping plate threadedly connected to the second one-way screw to cooperate with the first clamping plate to clamp and fix the area, and the second clamping plate slidably connected to the first clamping plate.

[0011] Preferably, the first clamping plate has a groove at the corresponding position of the second clamping plate, and the second clamping plate slides inside the groove.

[0012] The beneficial effects of this utility model are:

[0013] 1. The workpiece is positioned by the elastic plate and the ejector pin. The base position of the ejector pin and the workpiece is relatively sharp, so the contact area between them is small. Therefore, during the spraying operation, the contact position between the ejector pin and the workpiece will not affect the coating of the paint, thus eliminating the need for secondary processing and greatly improving work efficiency.

[0014] 2. The entire device can be fixed in any fixed position, and the entire device can be flipped to flip the fixed workpiece so that the area of ​​the workpiece to be sprayed is facing upwards, so as to facilitate the spraying operation and improve the spraying efficiency without disassembling the workpiece and re-clamping it.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-6 This utility model provides an embodiment of a spraying fixture for sprayed parts, including a limiting cylinder 1 and a baffle 21 slidably connected to the limiting cylinder 1. A flip angle adjustment component is fixedly connected to the limiting cylinder 1, and a positioning component with a fixed position is provided on the adjustment component. A mounting block 22 is fixedly connected to one side of the baffle 21, and an elastic plate 23 is fixedly connected to the side of the mounting block 22 away from the baffle 21. A ejector pin 24 is fixedly connected to the elastic plate 23. The elasticity of the elastic plate 23 allows the ejector pin 24 to position the workpiece. The positioning component clamps the workpiece in the area to be fixed. The sliding of the baffle 21 can adjust the position of the elastic plate 23 and the ejector pin 24. The position can be adjusted appropriately according to the size of the workpiece. The elastic plate 23 allows the ejector pin 24 to be locked inside the workpiece. The elasticity of the elastic plate 23 causes the ejector pin 24 to be tightened from inside the workpiece. The small ejector pin 24 contacts the workpiece, thereby performing the spraying operation. The limiting cylinder 1 can be flipped by the adjustment component, thereby flipping the workpiece. This positioning method is suitable for shell-shaped workpieces.

[0024] Please see Figures 1-4In this embodiment, two baffles 21 are provided, and the limiting cylinder 1 has matching grooves at corresponding positions of the two baffles 21. The two baffles 21 slide inside their respective grooves, and are staggered and fit together. The baffles 21 seal the internal space of the limiting cylinder 1, preventing paint from entering the limiting cylinder 1 during spraying, thus avoiding paint accumulation that could affect the normal use of the device. A first rotating block 25 is rotatably connected to the limiting cylinder 1. One end of the first rotating block 25 is fixedly connected to a bidirectional threaded rod 26. A sliding plate 27 is threadedly connected to the bidirectional threaded rod 26. The sliding plate 27 is fixedly connected to the side of the baffle 21 away from the mounting block 22. A first one-way threaded rod 28 is rotatably connected to the elastic plate 23. An adjusting elastic plate 28 is threadedly connected to the first one-way threaded rod 28. The limiting plate 29 has an opening angle of 3. A first nut 210 is threaded onto the first one-way threaded rod 28, and a second nut 211 is threaded onto the first one-way threaded rod 28. The first nut 210 and the second nut 211 cooperate to position the limiting plate 29. The opening size of the elastic plate 23 can be appropriately adjusted by the limiting plate 29 to facilitate quick clamping of the workpiece and avoid the opening being too large relative to the workpiece. The adjustment of the elastic plate 23 by the first one-way threaded rod 28 does not need to be too precise, so the paint can be manually cleaned after being sprayed on the first one-way threaded rod 28. The limiting plate 29 has a through groove, and the elastic plate 23 passes through the through groove. The limiting plate 29 contacts the elastic plate 23 through the through groove. The movement of the limiting plate 29 compresses the elastic plate 23, thereby controlling the opening size of the elastic plate 23. This is suitable for workpieces of different sizes.

[0025] Please see Figure 1 Figures 5-6In this embodiment, the adjusting assembly includes a positioning shell 31 fixedly connected to the limiting cylinder 1. A worm gear 32 is rotatably connected to the positioning shell 31. A second rotating block 33 is fixedly connected to one end of the worm gear 32. A worm wheel 34 meshes with the worm gear 32. A rotating shaft 35 is fixedly connected to the worm wheel 34 and rotatably connected to the positioning shell 31. Rotating the second rotating block 33 can flip the positioned workpiece, so that the surface to be sprayed faces the appropriate position for spraying operations. The positioning assembly includes a first clamping plate 41 fixedly connected to one end of the rotating shaft 35. A second one-way screw 42 is rotatably connected to the first clamping plate 41. The second clamping plate 43 is threadedly connected to the first clamping plate 41, which clamps and fixes the area. The second clamping plate 43 is slidably connected to the first clamping plate 41. The device can be fixed in any position by the cooperation between the second clamping plate 43 and the first clamping plate 41, such as fixing it to the edge of a table. It can be clamped on the table by the second clamping plate 43 and the first clamping plate 41. The first clamping plate 41 has a sliding groove at the corresponding position of the second clamping plate 43, and the second clamping plate 43 slides in the sliding groove. The sliding groove limits the second clamping plate 43, so that the second clamping plate 43 slides in a straight line to avoid deviation. The second clamping plate 43 can be flexibly raised and lowered by the rotation of the second one-way screw 42.

[0026] During operation, rotating the second rotating block 33 drives the worm gear 32, which in turn drives the worm wheel 34. The worm wheel 34 drives the rotating shaft 35, which in turn drives the first clamping plate 41. The angle of the first clamping plate 41 can be adjusted. Rotating the second one-way screw 42 drives the second clamping plate 43, which, in conjunction with the first clamping plate 41, clamps the first clamping plate 41 in a suitable position, fixing the position of the limiting cylinder 1. Rotating the first rotating block 25 drives the bidirectional threaded rod 26, which in turn drives the sliding plate 27. The sliding plate 27 drives the baffle 21, which in turn drives the installation... Block 22 and elastic plate 23 can adjust the distance between the two elastic plates 23. Then, first rotate the second nut 211 to move it away from the limiting plate 29. Then rotate the first one-way threaded rod 28 to drive the limiting plate 29 to move. The limiting plate 29 squeezes the elastic plate 23 and controls the opening angle of the elastic plate 23. When the opening angle reaches the appropriate position, the position of the limiting plate 29 is fixed by the cooperation of the first nut 210 and the second nut 211. Then, the workpiece is put on the ejector pin 24. The elasticity of the elastic plate 23 causes the ejector pin 24 to tighten from the inside of the workpiece and position the workpiece.

[0027] Through the above steps, the base position of the ejector pin 24 and the workpiece is relatively sharp, so the contact area with the workpiece is small. Therefore, during the spraying operation, the contact position between the ejector pin 24 and the workpiece will not affect the coating of the paint. This solves the problem that the contact area between the clamping component and the workpiece is large, which leads to the contact surface not being able to be sprayed, thus creating an exposed position that requires secondary processing.
