Description

Technical Field

[0001] The utility model belongs to the technical field of clamps, and in particular relates to a hole processing clamp used for an L-shaped special-shaped hydraulic cylinder. Background Art

[0002] Mud pump refers to a machine that delivers mud or water and other flushing fluids into the borehole during the drilling process. Mud pump is an important part of drilling equipment. The structure of one of the L-shaped special-shaped cylinders is as follows Figure 5 As shown in the figure, various holes need to be processed on the cylinder. The holes of the cylinder are usually processed on a vertical lathe. Due to the requirements of the processing technology, the cylinder often needs to be fixed upside down on the fixture of the vertical lathe. However, due to the asymmetry of the L-shaped cylinder structure, when it is clamped on the fixture for rotation processing, the force of the fixture will be seriously eccentric, which will not only cause the fixture to run eccentrically for a long time, greatly reducing the service life of the fixture, but also make the processed hole elliptical. Therefore, it is necessary to propose improvements. Utility Model Content

The utility model arranges a counterweight fixing component on the fixture base in view of the L-shaped structural characteristics of the mud pump hydraulic cylinder. The combination of the counterweight component and the hydraulic cylinder can balance the force on the fixture, avoid force eccentricity, and affect the service life of the fixture, and can ensure the quality of hole processing on the workpiece.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:
