Description

Technical Field

[0001] The utility model belongs to the technical field of piston rod processing, and more specifically, particularly relates to a piston rod processing and grinding device. Background Art

[0002] After the piston rod is cut, it needs to be fixed on the fixture of the grinding device, and then the motor drives the grinding disc to grind the piston rod to remove burrs and rust on the surface of the piston rod. At the same time, the fixture and the piston rod will rotate under the drive of another motor to ensure comprehensive grinding of the piston rod.

[0003] For example, CN219901413U discloses a piston rod grinding and processing equipment, which relates to the field of piston rod technology, and comprises: a device body, a fixed shell is fixedly installed on the bottom of the inner wall of the device body, a rotating motor is fixedly inserted on the inner surface wall of the fixed shell, a fixed frame is fixedly installed on the bottom of the inner wall of the device body, an electric telescopic rod A is fixedly inserted on the front surface of the fixed frame, a movable shell is fixedly installed on the output end of the electric telescopic rod A, a clamping frame is movably inserted between the opposite sides of the fixed shell and the movable shell, and the output end of the rotating motor is fixedly connected to one end of the outer wall of one of the two clamping frames, and two threaded rods A are rotatably inserted on the outer walls of the two clamping frames. Compared with the existing device, the device can start the electric telescopic rod to adjust the position of the movable shell according to the length of the piston rod, so that piston rods of different lengths can be clamped and rotated, thereby improving the versatility of the device.

[0004] Based on the above, after the grinding plate of the existing grinding device is worn, it is necessary to first remove all the bolts on the grinding plate. After the new grinding plate is installed, it is necessary to tighten multiple bolts one by one, which takes a long time. Not only does it cause a heavy labor burden on the staff, but it also affects the replacement efficiency of the grinding plate, resulting in a long downtime of the grinding device, which affects the processing efficiency of the piston rod.
