Description

Technical Field

[0001] The utility model relates to pipe fitting processing, in particular to a hydraulic pipe fitting processing device. Background Art

[0002] The existing patent CN202322087583.3, a polishing device for surface treatment, includes a polishing table. A polishing box is fixedly installed on the top of the polishing table. A sealing door is hinged on the right side of the polishing box. A clamping and rotating component and a grinding component are respectively arranged on the inner wall of the polishing box. The clamping and rotating component includes a shaft rod rotatably connected to the left side of the polishing box, and a driving box is fixedly installed corresponding to the shaft rod on the left side of the polishing box. This polishing device for surface treatment uses clamping claws to position the hydraulic pipe joint, controls the hydraulic rod to extend to drive the lifting plate to descend, and the driving motor drives the grinding disc to rotate, achieving the purpose of polishing the surface of the joint. After one side of the hydraulic pipe joint is polished, the stepping motor drives the worm to rotate. Based on the meshing of the worm and the worm gear, the shaft rod can be driven to rotate periodically by 60 degrees to polish the hexagonal surface of the hydraulic pipe joint. Since there is no need for manual adjustment of the polishing surface, the labor intensity of workers is reduced, and it is suitable for use in batch processing.

[0003] In the production and processing of hydraulic pipe fittings, based on the existing hydraulic pipe fitting fixtures in use, the following problems exist:

[0004] 1. The existing fixtures generally clamp on the outer surface, that is, the fixture contacts the outer surface of the hydraulic pipe fitting. When performing surface treatment on the hydraulic pipe fitting, the contact position between the surface of the hydraulic pipe fitting and the fixture cannot be surface-treated, and subsequent adjustment of the direction of the hydraulic pipe fitting for clamping is required, resulting in low practicability.

[0005] 2. When the existing fixtures fix the hydraulic pipe fittings, they cannot ensure the rotation of the pipe fittings while fixing them, resulting in only one side being treated during surface treatment, and the working efficiency is low. Summary of the Invention

The ends of the several first connecting rods far from the adjacent third connecting rods are fixedly connected to second connecting rods. The front end of the second connecting rod is movably connected to a first connecting plate. Arc-shaped plates are fitted to the left and right inner walls of the pipe fitting body.

[0008] Further, one side of each of the two arc-shaped plates corresponding to each other is fixedly connected to the adjacent first connecting plate.

[0009] Further, a bearing is fixedly connected to the middle of the U-shaped plate. A rotating shaft penetrates through the inner cavity of the bearing. The top of the rotating shaft is fixedly connected to the bottom of the electric telescopic rod.

[0010] Further, vertical plates are fixedly connected to both sides of the bottom of the U-shaped plate near the left and right sides. A cross plate is fixedly connected to the bottom between the two vertical plates near the bottom.

[0011] Further, a first bevel gear is fixedly connected to the bottom end of the rotating shaft. A second bevel gear is meshed with the right side of the first bevel gear. A rotating rod penetrates through the circular part of the second bevel gear. The left end of the rotating rod is movably connected to the vertical plate on the left side.
