Description

Technical Field

[0001] The utility model relates to the technical field of clamping devices, and particularly relates to a grinding clamping device for part production and processing. Background Technique

[0002] The clamping devices for part processing are an indispensable part of machining. Their main function is to firmly fix the workpiece on the processing equipment during the processing to ensure processing accuracy and safety. At present, especially when measuring the wall thickness, diameter, and ultrasonic testing of weld defects of pipe-shaped workpieces, it is necessary to fix the pipe parts, then grind the weld marks on the pipe, and perform weld detection operations through equipment. However, the current clamping devices are all in direct hard contact and directly use abutting blocks for hard clamping and limiting. Each detection and grinding requires the pipe to be rotated multiple times. However, when the pipe is rotated and displaced, it is easy to loosen, and it is necessary to re-tighten the bolts for fixation, which is time-consuming and laborious, and the rotation is inconvenient.

[0003] In view of the above problems, a grinding clamping device for part production and processing is needed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a grinding clamping device for part production and processing. In the utility model, the pipe fitting is placed between the U-shaped pressing block and the V-shaped abutting block, and then the first threaded rod is rotated. The first threaded rod presses on the cross plate, and the cross plate continuously presses on the pressing plate through the compression spring. The cross plate and the pressing plate slide along the sliding plate, so as to firmly fix the pipe through the U-shaped pressing block. When displacement is needed, directly rotate the first threaded rod, and then after the threaded rod is rotated, rotate the first threaded rod again to press and fix the pipe. The operation is simple and convenient, with high efficiency, time-saving and labor-saving. Then, between the base and the second threaded rod, directly place the part between the abutting disc and the side wall of the base, and then rotate the second threaded rod to abut and tighten the part. After the part is fixed, according to the direction requirement, directly screw the first support rod or the second support rod into the corresponding first threaded connection hole or the second threaded connection hole, and the whole device can be placed in a suspended state, which is convenient for the staff to detect the part in all directions.

[0005] The utility model is realized as follows. The utility model includes a base, on which clamping blocks are fixedly arranged at intervals. A first rotating shaft is arranged on one side of the clamping blocks, and a U-shaped rod is rotationally connected through the first rotating shaft; at the other end of the U-shaped rod, a second rotating shaft is arranged, and the second rotating shaft is connected with a hook.
