Embodiment Construction

[0015] The working mode of the present invention will be further described below in conjunction with the accompanying drawings.

[0016] Such as figure 2 , image 3 As shown, the external threaded single-acting hydraulic cylinder-13 is connected to the oil passages 6, 8, and 11 through threads, and is used to clamp the single-acting piston rod-5.

[0017] The first step: if figure 1 As shown, the swimming matrix hydraulic cylinder cooperates with the base through the dovetail groove and moves longitudinally on the base through the thread transmission of the screw rod. According to the size of the workpiece to be clamped, the opening size of the fixture is determined by adjusting the screw rod-1. Use other tools to place the special-shaped workpiece in the middle of the fixture, and pass low-pressure hydraulic oil into the fixed matrix cylinder-10 through the oil circuit control part to push the piston rod out and make each piston rod contact with the outer wall of the w...

Abstract

The invention provides a hydraulic clamping device for a special-shaped workpiece. The hydraulic clamping device is suitable for machine tools. The hydraulic clamping device is mainly composed of a base, a fixed matrix hydraulic cylinder and a movable matrix hydraulic cylinder. The movable matrix hydraulic cylinder is matched with the base through dovetail grooves, and longitudinally moves on the base through transmission of a lead screw. The matrix hydraulic cylinders are internally provided with single-action piston-type hydraulic rods resetting through springs, hydraulic oil with appropriate pressure is fed into the hydraulic cylinders, the pressure is transmitted to the hydraulic rods, and therefore the hydraulic rods position and clamp the workpiece. Due to the fact that the extension length of each hydraulic rod can be adjusted through hydraulic parts, the clamping range is not constant, and the hydraulic clamping device can clamp the irregular special-shaped workpiece. The process of reserving unnecessary technological structures on the clamped workpiece according to clamping requirements of the workpiece during machining and formulating the related technique is simplified, workpiece materials are saved, the machining technology is simplified, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to a hydraulic clamping device for workpieces with special shapes, which is suitable for machine tools. Background technique [0002] In the existing machine tool fixtures, the workpiece is required to be made into a regular shape for easy clamping, and the workpiece needs to reserve redundant technological structures and formulate related technological processes on the workpiece according to the clamping needs during processing, which wastes materials and consumes man-hours. Contents of the invention [0003] Aiming at the deficiency of existing machine tool fixtures, the present invention provides a simple and reliable hydraulic fixture that can directly clamp special-shaped workpieces. [0004] The scheme of the present invention to solve the above-mentioned problems is as follows: the clamp is mainly composed of a base, a fixed matrix hydraulic cylinder and a traveling matrix hydraulic cylinder. The traveling matrix hydrauli...
