[0001] This utility model relates to the field of metal parts processing technology, specifically to a stable fixture for metal parts processing. Background Technology

[0002] Metal parts refer to a collective term for metal blocks, rods, tubes, etc., of various specifications and shapes made of metal materials. During the production of metal parts, to improve their corrosion resistance, aesthetics, and functionality, surface coatings are often applied. Metal tubes, in particular, require coating of both the inner and outer walls. Conventional clamps typically only hold the outer wall of the metal part, preventing complete coating. The tube must be removed, its position adjusted, and a second coating applied to achieve full coating of the outer wall, resulting in low processing efficiency.

[0003] In view of the technical problems in the spraying of metal pipes, this application proposes a stabilizing fixture for the processing of metal parts. Utility Model Content

[0004] I. Technical problems to be solved

[0005] The technical problem this invention aims to solve is that conventional clamps mostly hold the outer wall of metal parts, which prevents the outer wall of metal pipes from being fully coated. The metal pipes need to be removed for secondary coating, resulting in low processing efficiency.

[0006] II. Technical Solution

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a stable fixture for processing metal parts, including a base plate and a mounting plate, wherein multiple sets of support legs are connected between the lower side of the mounting plate and the base plate, a through hole is provided in the middle of the mounting plate, a mounting frame passes through the through hole, an internal tube clamping assembly is mounted on the mounting frame, and external tube clamping assemblies are respectively mounted on both sides of the mounting plate, and the tube is clamped by the internal tube clamping assembly and the external tube clamping assembly respectively;

[0008] The tube clamping assembly includes a threaded shaft and multiple clamping blocks.

A motor for driving the threaded shaft to rotate is installed inside the mounting frame. A positioning block is rotatably mounted on the top of the threaded shaft. Support rods are rotatably connected between the upper and lower sides of the clamping blocks and the positioning block and the movable block, respectively.

[0009] The external clamping assembly includes two sets of rotating frames. The lower sides of the two sets of rotating frames are rotatably connected to the mounting plate through a linkage assembly. A V-shaped clamping frame is installed on the upper side of the rotating frame.

[0010] As an improvement, the linkage assembly includes two sets of rotating shafts and two sets of gears. Multiple sets of mounting blocks are installed on the lower side of the mounting plate. The rotating shaft rotates through the two sets of mounting blocks on the same side and one end is connected to the gear. The two sets of gears mesh with each other. A second motor for driving the rotating shaft is installed on one set of the mounting plate. The lower side of the rotating frame is sleeved on the outside of the rotating shaft.

[0011] As an improvement, the mounting plate is provided with U-shaped grooves on both sides for the rotating frame to pass through during rotation.

[0012] As an improvement, multiple sets of anti-slip strips are installed on the inner side of the V-shaped clamp.

[0013] As an improvement, a positioning rod is fixedly installed between the lower side of the positioning block and the upper side of the mounting frame, and the moving block is slidably sleeved on the outside of the positioning rod.

[0014] As an improvement, an electric telescopic rod passes through the base plate, and the extended end of the electric telescopic rod is connected to the lower side of the mounting frame.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0025] When applying a full coat of paint to the outer wall of the pipe fitting, as shown in the attached image... Figure 1 Appendix Figure 2 and attached Figure 5 As shown, a stabilizing fixture for processing metal parts includes a base plate 1 and a mounting plate 2. Multiple sets of support legs 3 are connected between the lower side of the mounting plate 2 and the base plate 1. The base plate 1 is mounted on a spraying trolley and can be driven to rotate 360° reciprocally by a drive device. The mounting plate 2 has a through hole 14 in the middle, through which a mounting frame 5 passes. An electric telescopic rod 4 passes through the base plate 1, and the extended end of the electric telescopic rod 4 is connected to the lower side of the mounting frame 5. The upper part of the mounting frame 5 is frustum-shaped, and the lower end of the pipe 23 is supported on the side wall of the frustum-shaped part of the mounting frame 5. The entire pipe 23 is located on the upper side of the mounting plate 2, which facilitates the spraying equipment to spray the outer wall of the pipe 23.

[0026] As attached Figure 3As shown, an internal clamping assembly is installed on the mounting frame 5. The internal clamping assembly includes a threaded shaft 8 and multiple sets of clamping blocks 12. The threaded shaft 8 is rotatably mounted on the upper side of the mounting frame 5, and a moving block 11 is threadedly connected to its outer side. A motor 6 that drives the threaded shaft 8 to rotate is installed inside the mounting frame 5. Multiple sets of heat dissipation vents 7 are provided on the lower side wall of the mounting frame 5 to dissipate the heat generated by the motor 6. A positioning block 9 is rotatably mounted on the top of the threaded shaft 8. A positioning rod 10 is fixedly installed between the lower side of the positioning block 9 and the upper side of the mounting frame 5. The moving block 11 slides on the outer side of the positioning rod 10. The mechanism is controlled by an external control unit. The starting motor 6 drives the threaded shaft 8 to rotate. The positioning rod 10 limits the positioning block 9 and the moving block 11 to prevent them from rotating with the threaded shaft 8. The moving block 11 moves up and down on the outside of the threaded shaft 8 via the thread. The clamping block 12 is rotatably connected to the positioning block 9 and the moving block 11 on its upper and lower sides. By moving the moving block 11 towards the positioning block 9, the included angle between the two sets of support rods 13 connected to the clamping block 12 is reduced, and the clamping block 12 is pushed towards the inner wall of the pipe fitting 23. The multiple sets of clamping blocks 12 support the inner wall of the pipe fitting 23 and position the pipe fitting 23, enabling full spraying of the outer wall of the pipe fitting.

[0027] When applying a full coat of paint to the inner wall of the pipe fitting, as shown in the attached image... Figure 2 and attached Figure 4 As shown, external clamping assemblies are installed on both sides of the mounting plate 2. Each external clamping assembly includes two sets of rotating frames 19. The lower sides of the two sets of rotating frames 19 are rotatably connected to the mounting plate 2 via a linkage assembly. The linkage assembly includes two sets of rotating shafts 16 and two sets of gears 17. Multiple sets of mounting blocks 15 are installed on the lower side of the mounting plate 2. The rotating shaft 16 rotates through two sets of mounting blocks 15 on the same side, and one end is connected to the gear 17. A second motor 18 for driving the rotating shaft 16 is installed on one set of the mounting plate 2. The lower side of the rotating frame 19 is sleeved on the outside of the rotating shaft 16. The second motor 18 is started by an external control unit. A set of rotating shafts 16 are driven to rotate by a motor 18. Two sets of gears 17 mesh to achieve opposite rotation of the two sets of rotating shafts 16. The rotating shafts 16 drive the rotating frame 19 to rotate. The mounting plate 2 has U-shaped grooves 22 on both sides to allow the rotating frame 19 to rotate through. A V-shaped clamping frame 20 is installed on the upper side of the rotating frame 19. The rotating frame 19 drives the V-shaped clamping frame 20 to rotate upward, clamping the two sets of V-shaped clamping frames 20 on the outer wall of the pipe fitting 23. Multiple sets of anti-slip strips 21 are installed on the inner side of the V-shaped clamping frame 20. The multiple sets of anti-slip strips 21 clamp the outer wall of the pipe fitting 23 after the paint has dried, preventing the pipe fitting 23 from sliding.

[0028] When motor 6 reverses, clamping block 12 releases its support from pipe fitting 23. The electric telescopic rod 4 retracts, moving the internal clamping assembly out from under pipe fitting 23. At this time, the spraying equipment is inserted into pipe fitting 23 to spray the inner wall of pipe fitting 23 evenly. By clamping pipe fitting 23 with the internal clamping assembly and the external clamping assembly respectively, the outer wall of the metal pipe fitting can be fully sprayed, improving processing efficiency.
