Description

Technical Field

[0001] The utility model relates to the technical field of hardware pipe fitting processing, in particular to a clamp used for plastic spraying of hardware pipe fittings. Background Art

[0002] Plastic spraying of hardware pipe fittings is a surface treatment method of spraying plastic powder on pipe fittings. It can optimize the appearance of pipe fittings, enhance the corrosion resistance and wear resistance of pipe fittings, and has the advantages of simple construction without primer, low technical requirements for workers, and lower cost than painting process.

[0003] According to the patent number CN 220126640 U, ​​a clamp for spraying plastics on hardware pipe fittings includes a base plate, a vertical plate, a rotating shaft, a mounting assembly, a pulley 1, a pulley 2, a baffle, a support rod, a motor 1, an adjustment assembly, etc. The distance between the four locking rods of the mounting assembly has a certain adjustment range, so the hardware pipe fittings within a certain pipe diameter range can be conveniently installed using the mounting assembly, and the distance between the two mounting assemblies can be adjusted. However, the existing clamp for spraying plastics on hardware pipe fittings only positions the pipe fittings by means of springs, and when positioning hardware pipe fittings with larger pipe diameters, the spring is in a strong compression state, and the supporting force on the outer wall of the pipe fitting is large, which is easy to cause damage to the outer wall of the pipe fitting. When positioning hardware pipe fittings with smaller pipe diameters, the spring is in a weak compression state, or even no compression, resulting in a poor positioning effect on the pipe fittings. Therefore, the pipe fittings positioned by the device are relatively limited. For this reason, we propose a clamp for spraying plastics on hardware pipe fittings. Utility Model Content

When adjusting the distance between the first upright plate 2 and the second upright plate 3, the servo motor 8 is controlled to work to make the bidirectional screw rod 6 rotate forward, and the first upright plate 2 and the second upright plate 3 are brought closer to each other through the threaded connection between the two slide plates 7 and the two ends of the bidirectional screw rod 6. Then, according to the diameter of the hardware pipe fittings to be sprayed, the opening degree of the four connecting rods 16 on the support plate 13 is adjusted. First, the handle 20 is turned to rotate the threaded rod 19, and the slider 11 is moved in the direction away from the support plate 13 through the threaded connection between the threaded rod 19 and the slider 11. The sliding of the slider 11 The connecting rod 16 is pulled to move, and the four connecting rods 16 are brought close to each other at this time, and then the two calibers of the hardware pipe fittings are respectively sleeved on the outside of the four connecting rods 16 on the two supporting plates 13, and the arc-shaped supporting rods 17 on the connecting rods 16 are in contact with the inner wall of the pipe, and then the screw handle 20 is rotated in the opposite direction to move the slider 11 toward the supporting plate 13, so that the four connecting rods 16 are opened, and the inner wall of the hardware pipe fittings is tightly supported, and the two hardware pipe fitting positioning mechanisms 4 tighten the two ends of the pipe fittings, so that the hardware pipe fittings are firmly supported, and the outer wall of the pipe fittings is completely exposed to the outside, which is convenient for spraying.

[0023] The hardware pipe positioning mechanism 4 includes a fixed rod 10, a support plate 13, a sliding block 15, a connecting rod 16 and an arc-shaped support rod 17.

At this time, the four connecting rods 16 are close to each other, and then the two calibers of the hardware pipe fittings are respectively sleeved on the outside of the four connecting rods 16 on the two support disks 13, and the arc-shaped support rods 17 on the connecting rods 16 contact the inner wall of the pipe. Then, turn the handle 20 in the opposite direction to move the slider 11 toward the support disk 13, so that the four connecting rods 16 are opened, and the inner wall of the hardware pipe fitting is tightly supported, and the two hardware pipe fitting positioning mechanisms 4 tighten the two ends of the pipe fittings, so that the hardware pipe fittings are firmly supported, and the outer wall of the pipe fittings is completely exposed to the outside, which is convenient for spraying.
