Description

Technical Field

[0001] This utility model relates to the field of parts coating technology, specifically to a clamping and positioning device for parts coating processing. Background Technology

[0002] To ensure that the coating on the surface of the parts can be applied stably to achieve special effects, such as corrosion prevention, oxidation prevention, and increased hardness, it is usually necessary to clamp and position them first.

[0003] Existing clamping and positioning devices for coating parts are mostly designed to fix only parts of the same type, and then use a spraying device to coat their surfaces. After one side is coated, the parts are flipped over to coat the other side. Because the clamping and positioning devices are designed for specific types, their applicability is low. In addition, the flipping process not only reduces processing efficiency, but also easily leads to uneven coating of parts. Furthermore, excess paint is wasted, increasing costs.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Combined with appendix Figure 1 , Figure 2 and Figure 3 To achieve synchronous movement of the clamping blocks 3 for clamping and limiting the parts, a clamping and positioning device for coating processing of parts includes a base 1, a mounting base 2, and several clamping blocks 3. The clamping blocks 3 are slidably connected to the mounting base 2. The mounting base 2 is connected to a driving component in a driving cavity 4, which can drive the clamping blocks 3 to move closer or further apart. The driving component includes a cavity connected to the mounting base 2. Several sliding holes 9 are evenly distributed in an array at the top of the cavity. A slider 10 is slidably connected in the sliding holes 9. The top of the slider 10 is connected to the clamping block 3. A hinge rod 11 is hinged to the bottom of the slider 10. The other end of the hinge rod 11 is hinged to a sliding sleeve 12. A lifting component is connected to the sliding sleeve 12. The lifting component drives the sliding sleeve 12 to rise and fall. The sliding sleeve 12 drives the slider 10 through the hinge rod 11, causing the clamping blocks 3 to slide synchronously along the direction of the sliding holes 9, thereby driving the clamping blocks 3 to move closer or further apart synchronously.

[0025] In order to drive the hinge rod 11 to move synchronously with the clamping block 3 through the lifting and lowering of the sliding sleeve 12, combined with the attached Figure 2 and Figure 3The lifting assembly includes a second motor 13 connected to the bottom of the mounting base 2. The power output end of the second motor 13 is connected to a third bevel gear 14. A drive rod 15 is rotatably connected between the top wall of the cavity and the bottom wall of the drive cavity 4. A fourth bevel gear 16 is connected to the bottom of the drive rod 15. The fourth bevel gear 16 meshes with the third bevel gear 14. The drive rod 15 passes through the extension cylinder 7 and the bottom wall of the mounting base 2 and passes through the sliding sleeve 12 at the top via a thread.

[0026] In order for the clamping block 3 to clamp ring-shaped, cylindrical, or block-shaped parts, combined with the attached Figure 1 , Figure 2 and Figure 5 The clamping blocks 3 are an even number and are evenly distributed and slidably disposed on the mounting base 2. Each clamping block 3 is a fan-shaped block with a fan-shaped stepped groove 17 connected to its inner side. The outer periphery of each clamping block 3 is provided with an anti-slip layer. Block-shaped parts can be placed between relative clamping blocks 3, and the block-shaped parts can be clamped by the side walls of the clamping blocks 3 moving closer to each other. When the part is cylindrical, the part can be placed at the fan-shaped stepped groove 17, and the block-shaped parts can be clamped by driving the clamping blocks 3 to move closer to each other and using the outer walls of the stepped grooves. When the part is annular, the part can be placed at the outer wall of the clamping block 3, and the block-shaped parts can be clamped by driving the clamping blocks 3 to move away from each other and using the outer walls of the clamping blocks 3.

[0027] Example 2

[0028] To achieve uniform coating, combined with the attached Figure 2 The mounting base 2 is slidably connected to the top of the base 1. The top of the base 1 is provided with an annular groove. The mounting base 2 has dovetail blocks on both sides that slide with the sliding ring. The base 1 has a driving cavity 4 in the middle. The driving cavity 4 is connected to a rotating component that can drive the mounting base 2 to rotate in order to achieve a uniform coating. The rotating component includes a first motor 5 connected to the bottom wall of the driving cavity 4. The power output end of the first motor 5 is connected to a first bevel gear 6. The bottom center of the mounting base 2 is connected to an extension cylinder 7. The extension cylinder 7 is connected to a second bevel gear 8. The second bevel gear 8 meshes with the first bevel gear 6. The first motor 5 drives the second bevel gear 8 to rotate the extension cylinder 7 and the mounting base 2 through the meshing of the first bevel gear 6 and the second bevel gear 8, thereby allowing the parts to rotate and achieve uniform coating of the parts.

[0029] Example 3

[0030] To recycle excess paint and avoid waste, combined with... Figure 2 and Figure 4The base 1 is connected to a recycling component for recycling paint. The recycling component includes an annular groove 18 connected to the outer side of the top of the mounting base 2. The annular groove 18 has a V-shaped cross-section. The base 1 is circumferentially connected to a recycling trough 19. Several through holes 20 are provided between the recycling trough 19 and the annular groove 18. An outlet pipe is connected to one side of the bottom of the recycling trough 19. In order to ensure recycling efficiency, a negative pressure device that can suck up excess paint above the mounting base can also be installed in the recycling trough.

[0031] The specific usage method is as follows:

[0032] First, the driving assembly moves the clamping blocks 3 closer or further apart, facilitating the clamping and limiting of parts of different types and sizes. Then, the second motor 13 is activated, driving the third bevel gear 14. The third bevel gear 14 meshes with the fourth bevel gear 16, causing the drive rod 15 to rotate. The drive rod 15, through its threaded engagement with the sliding sleeve 12, drives the sliding sleeve 12 to move up and down. The sliding sleeve 12, via the hinge rod 11, drives the slider 10, causing the clamping blocks 3 to slide synchronously along the sliding hole 9, thus achieving the driving of the clamping blocks 3. Simultaneously moving closer or further away, if the part is block-shaped, it can be placed between the relative clamping blocks 3, and then the side walls of the clamping blocks 3 can move closer to each other to clamp the block-shaped part; when the part is cylindrical, it can be placed at the fan-shaped stepped groove 17, and the clamping blocks 3 can be driven to move closer to each other to clamp the block-shaped part together through the outer wall of the stepped groove; when the part is annular, it can be placed at the outer wall of the clamping block 3, and the clamping blocks 3 can be driven to move further away to clamp the block-shaped part together through the outer wall of the clamping block 3.

[0033] Then, the rotating component drives the mounting base 2 to rotate the clamping block 3 and the part. By starting the first motor 5, the first motor 5 drives the first bevel gear 6. The first bevel gear 6 drives the extension cylinder 7 and the mounting base 2 to rotate through meshing with the second bevel gear 8, thereby allowing the part to rotate to achieve uniform spraying of the part.

[0034] The recycling component facilitates the recycling and reuse of excess paint. Excess paint falls onto the top of the mounting base 2 and is guided into the annular groove 18 by centrifugal force generated by the rotation of the rotating component. Then, it is guided into the recycling tank 19 through the through hole 20 for recycling and reuse, thereby reducing waste.
