Hydraulic bench clamp and workpiece clamping method using same

Abstract

The invention provides a multi-functional hydraulic bench clamp which comprises a vice bench body 1, a pushing piston 2, a plurality of driven pistons 3 and a fixing jaw which is fixed on the vice bench; the pushing piston which is arranged inside the vice bench body 1 is capable of performing reciprocating motion; the pushing pistons which are arranged inside the vice bench body 1 are capable of performing reciprocating motion; a hydraulic pipeline 11 which is used for holding hydraulic oil 6 is formed inside the vice bench body 1; the pushing piston 2 is arranged inside the hydraulic pipeline 11 and can perform reciprocating motion inside the hydraulic pipeline 11; positions of the hydraulic pipeline 11, which are outside the vice bench body 1, are provided with a plurality of openings; the plurality of driven pistons are arranged inside the he hydraulic pipeline 11 and can perform reciprocating motion inside the hydraulic pipeline 11; and bottoms of the driven pistons stretch into the hydraulic pipeline 11. The multi-functional hydraulic bench clamp has the advantages of achieving clamping of a plurality of small-sized workpieces at the same time and guaranteeing the clamping force the clamped workpieces bear is uniform and improving the efficiency of machining of the small-sized workpieces through a numerical control machine tool.

Description

technical field [0001] The invention relates to a clamping device, in particular to a hydraulic vise suitable for quickly clamping various small precision workpieces. Background technique [0002] At present, the hydraulic vise commonly used in metal cutting is large in size and is not suitable for clamping workpieces with small dimensions and irregular shapes, and generally can only clamp one workpiece at a time. It has a single function and low efficiency, which is difficult to meet Requirements for batch processing of various small precision workpieces. Contents of the invention [0003] Aiming at the problem that the prior art cannot meet the batch processing requirements of various small precision workpieces, the present invention provides a hydraulic vise, which includes a vise main body 1 and a reciprocating push piston 2 placed inside the vise main body 1 , a plurality of reciprocating driven pistons 3 mounted on the main body 1 of the vice, and fixed jaws 4 fixed...
