Description

Technical Field

[0001] This utility model relates to the field of workpiece surface treatment technology, and in particular to a placement fixture for workpiece surface treatment. Background Technology

[0002] The main functions of electrostatic powder coating include corrosion protection, aesthetic enhancement, and improved wear resistance. Electrostatic powder coating uses electrostatic adsorption to evenly spray powder onto the surface of an object, forming a protective coating. This coating has excellent anti-corrosion properties, effectively preventing corrosion and oxidation of the coated surface.

[0003] During operation, the tool that matches the workpiece is fixed on the placement table. Then, the outer shell workpiece is placed on the mold. The table surface is rotated, which drives the mold and workpiece to rotate. Different parts of the workpiece are sprayed. Depending on the workpiece, the same mold needs to be placed on the placement table. Generally, it is fixed to the placement table with multiple bolts. However, it is quite troublesome to disassemble and install by tightening each nut and bolt. Utility Model Content

[0004] The purpose of this invention is to provide a placement fixture for workpiece surface treatment that has the advantage of facilitating mold installation.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A fixture for placing workpieces for surface treatment includes a base, a vertical support rod rotatably connected to the base, a mounting plate fixedly connected to the upper end of the support rod, a support fixedly connected to the mounting plate, a cavity fixedly connected to the upper part of the support, an opening on the bottom surface of the cavity, a mold placed on the bottom surface of the cavity, a connecting block fixedly connected to the bottom of the mold, and multiple sliding grooves formed therein, with clamping blocks passing through the sliding grooves. The outer walls of the clamping blocks on both sides are slidably connected to the inner walls of the sliding grooves on both sides, and an elastic element is provided between the clamping blocks and the inner walls of the sliding grooves. The clamping block is wider at the top and narrower at the bottom when it is located below the connecting plate, thus forming a wedge-shaped surface on one side of the clamping block located below the connecting plate. A vertical groove is provided on one side of the cavity. A vertically downward threaded cylinder is rotatably connected to the bottom of the support. A screw is threadedly connected to the threaded cylinder. A connecting rod is fixedly connected to the upper end of the screw. The end of the connecting rod passes through the groove of the cavity. A push plate is fixedly connected to the end of the connecting rod located inside the cavity. A groove is provided on the surface of the push plate. The groove is wider at the top and narrower at the bottom, so that its sidewall matches the wedge-shaped surface of the clamping block.

[0007] Using the above technical solution, the workpiece template is placed above the opening of the cavity. The connecting block at the bottom of the template is located between multiple clamping blocks inside the cavity. Tightening the threaded cylinder prevents the screw threaded to the cylinder from rotating due to the constraint of the cavity. The threaded sleeve pushes the screw vertically upwards. The screw, through the connecting rod, drives the push plate upwards towards the clamping block, causing the sidewall of the push plate's groove to contact the wedge-shaped surface of the clamping block. As the push plate continues to rise, the sidewall of the groove exerts a force on the wedge-shaped surface of the clamping block, pushing the pressure block horizontally towards the connecting block and clamping it. This clamps and fixes the connecting block to the support. Simultaneously, the connecting block exerts a force on the elastic element, causing it to elasticate. Similarly, rotating the threaded cylinder in the opposite direction causes the screw to move vertically downwards, pushing the push plate downwards. The inner wall of its groove gradually moves away from the wedge-shaped surface of the clamping block, and the elastic element rebounds, pushing the connecting block away from the clamping block. This allows the mold to be removed from the cavity above the support for replacement without the need for multiple bolts, making operation more convenient.

[0008] Preferably, the support rod is fixedly connected to the mounting plate with reinforcing ribs.

[0009] The above technical solution increases the stability of the mounting plate.

[0010] Preferably, a second cavity is fixedly connected to the upper part of the support. The second cavity has the same structure as the first cavity. The two ends of the connecting rod are respectively inserted into the first cavity and the second cavity, and the two ends of the connecting rod are respectively fixedly connected to the push plates inside the two cavities.

[0011] Using the above technical solution, molds are placed on the two cavities, the threaded cylinder is rotated to drive the screw, and the screw drives the push plate in the two cavities to rise through the connecting rod. The push plate pushes the clamping block to clamp the mold, thereby fixing the mold. Then, the workpiece is placed on each mold, so that the two molds can be sprayed at the same time, increasing work efficiency.

[0012] Preferably, the base includes multiple support legs, each of which is obliquely and fixedly connected to the same connecting cylinder. A bearing is fixedly connected inside the connecting cylinder, and the support rod passes through the bearing and is fixedly connected to the inner ring of the bearing.

[0013] By adopting the above technical solution, the resistance encountered by the support rod during rotation is reduced by setting a bearing between the support rod and the base.

[0014] Preferably, the upper part of the support is fixedly connected to two vertical guide rods, and the connecting rod is located between the two guide rods and in contact with the two guide rods.

[0015] Using the above technical solution, the screw drives the connecting rod to move vertically between the two guide rods, and the guide rods guide the movement of the moving plate, increasing its motion stability.

[0016] Preferably, the elastic element is a spring.

[0017] Using the above technical solution, the pusher plate pushes the clamping block closer to the connecting block, the clamping block compresses the spring, the pusher plate moves away from the clamping block, and the spring rebounds to push the clamping block and the connecting block apart.

[0018] Preferably, the threaded cylinder is externally fixedly connected with a handle.

[0019] The above technical solution facilitates the rotation of the threaded cylinder. Attached Figure Description

[0028] See Figures 1 to 6A fixture for placing workpieces for surface treatment includes a base 1 and a support rod 2. The base 1 includes multiple support legs, each of which is obliquely and fixedly connected to the same connecting cylinder. A bearing is fixedly connected inside the connecting cylinder, and the support rod 2 passes through the bearing, with an interference fit between the support rod 2 and the bearing. A mounting plate 3 is welded to the upper end of the support rod 2, and a reinforcing rib 16 is welded between the support rod 2 and the mounting plate 3. A support 4 is fixedly connected to the mounting plate 3 by bolts and nuts. The bolts pass through the mounting plate 3 and the support 4, and the nuts are screwed onto the bolts. The bottom surfaces of the mounting plate 3 and the support 4 are located between the nut and the tail of the bolt. A cavity 1 5 and a cavity 2 are welded to the upper part of the support 4. An opening is opened on the bottom surface of the cavity 1 5, and a mold 6 is placed on the bottom surface of the cavity 1 5. A connecting block 7 is integrally formed at the bottom of the mold 6 and is located inside the cavity 1 5. A connecting plate 8 is fixedly connected inside cavity 5. The connecting plate 8 has multiple sliding grooves, and clamping blocks 9 pass through these grooves. The outer walls of the clamping blocks 9 are slidably connected to the inner walls of the sliding grooves on both sides. A spring 18 is fixedly connected between the clamping blocks 9 and the inner walls of the sliding grooves. The portion of the clamping blocks 9 located below the connecting plate 8 is wider at the top and narrower at the bottom, thus forming a wedge-shaped surface 10 on one side of the portion of the clamping blocks 9 located below the connecting plate 8. Vertical sliding grooves are provided on the side of cavity 5. Cavity 5 and cavity 2 have the same structure. The bottom of the support 4 is rotatably connected to a vertically downward threaded cylinder 11. The threaded cylinder 11 is threadedly connected to a screw 12. The upper end of the screw 12 is fixedly connected to a connecting rod 13. Two vertical guide rods 17 are welded to the upper part of the support 4. The connecting rod 13 is located between the two guide rods 17 and contacts the two guide rods 17. The two ends of the connecting rod 13 pass through the sliding grooves of the two cavities and enter their interiors. Push plates 14 are welded to the two ends of the connecting rod 13 located inside the two cavities. The surface of the push plate 14 is provided with a groove 15. The groove 15 is wider at the top and narrower at the bottom, so that its sidewall matches the wedge-shaped surface 10 of the clamping block 9.

[0029] Working principle: The workpiece template is placed above the opening of cavity 5. The connecting block 7 at the bottom of the template is located between multiple clamping blocks 9 inside cavity 5. The threaded cylinder 11 is turned, and the screw 12, which is threaded to the threaded cylinder 11, will not rotate due to the restriction of the connecting rod 13, which is fixedly connected to it, by cavity 5. As a result, the threaded sleeve will push the screw 12 to move vertically upward. The screw 12 drives the push plate 14 to rise and approach the clamping block 9 through the connecting rod 13, so that the side wall of the groove 15 of the push plate 14 contacts the wedge-shaped surface 10 of the clamping block 9. The push plate 14 continues to rise, and the side wall of the groove 15 exerts a force on the wedge-shaped surface 10 of the clamping block 9, pushing the pressure block to move horizontally and approach the connecting block 7. The moving clamping block 9 compresses the spring 18, generating elasticity. Then the clamping block 9 clamps the connecting block 7, thereby clamping the connecting block 7 and fixing the mold 6 on the support 4. Then, the workpiece is placed on each mold 6, so that two molds 6 can be sprayed at the same time. Similarly, the threaded cylinder 11 is rotated in the opposite direction. The threaded cylinder 11 drives the screw 12 to move vertically downward, pushes the plate down, and the inner wall of its groove 15 gradually moves away from the wedge surface 10 of the clamping block 9. The spring 18 rebounds and pushes the clamping block 9 to separate from the connecting block 7, so that the mold 6 can be removed from the cavity on the upper part of the support 4 for replacement without the need to tighten multiple bolts, making the operation more convenient.
