Novel pneumatic hydraulic synchronous clamp device

Abstract

The invention provides a novel pneumatic hydraulic synchronous clamp device which comprises clamping blocks, sliding blocks, a clamp base, triangle levers, a horizontal pressing plate, a pin shaft, apressure cylinder, a piston, a horizontal dustproof plate and a fixing shaft sleeve. A containing cavity is formed in the clamp base. A piston capable of moving up and down along the shaft in a reciprocating manner is coaxially installed in the containing cavity of the clamp base. The lower portion of the piston is in transmission connection with the pressure cylinder installed below the clamp base. The triangle levers are connected to the left side and the right side of the piston correspondingly. The sliding blocks capable of moving left and right in a reciprocating manner are connected above the triangle levers. One clamping block is fixed to each sliding block. The horizontal pressing plate connected with the clamp base is further arranged between the sliding blocks and the clamping blocks. According to the lever principle, the pressure cylinder is utilized for moving up and down to pull the levers to control the left sliding block and the right sliding block to move in the same direction or the opposite directions, and it is ensured that the center is located automatically for clamping a workpiece.

Description

technical field [0001] The invention belongs to a clamp, in particular to a novel pneumatic-hydraulic synchronous clamp device. Background technique [0002] A fixture is a device used to fix the processing object in the process of mechanical manufacturing so that it occupies the correct position for construction or inspection. In a broad sense, any process in the process, the device used to install the workpiece quickly, conveniently and safely, can be called a fixture. Such as welding fixtures, inspection fixtures, assembly fixtures, machine tool fixtures, etc. Among them, machine tool fixtures are the most common, often referred to as fixtures. When processing a workpiece on a machine tool, in order to make the surface of the workpiece meet the technical requirements such as the size, geometric shape, and mutual position accuracy with other surfaces specified in the drawing, the workpiece must be installed (positioned) and clamped (clamped) before processing. . The fi...

Problems solved by technology

[0003] However, in the clamping process of existing fixtures, the grippers are not synchronized, the accuracy is not high, and there are disadvantages such as the inability to automatically locate the center of the workpiece or low positioning accuracy, which reduces the qualified rate of workpiece processing and wastes a lot of manpower and material resources
