Two-way free series connecting rod cylinder

Abstract

The invention relates to a work fixture, in particular to a bi-directional free concatenation connecting rod air cylinder which comprises a cylinder body; the cylinder body comprises a left cylinder body and a right cylinder body; a left piston rod is arranged at the axis of the left cylinder body; a right piston rod is arranged at the axis of the right cylinder body; a left air passage is arranged in the middle of the left cylinder body in a penetrating manner; a right air passage is arranged in the middle of the right cylinder body in a penetrating manner; a left air opening communicating with the left air passage and a middle air opening are formed the side wall of the left cylinder body; a right air opening communicating with the right air passage is formed the side wall of the right cylinder body; a middle cylinder body is arranged between the left cylinder body and the right cylinder body; and a communicating air passage communicating with the left air passage and the right air passage is formed in the middle of the middle cylinder body. The bi-directional free concatenation connecting rod cylinder has the beneficial effects that the stroke can be changed according to actual needs, expansion can be realized in both directions, and the expansion direction can be changed as needed.

Description

technical field [0001] The invention relates to a tooling fixture, in particular to a two-way free series connecting rod cylinder. Background technique [0002] With the continuous development of the machinery manufacturing industry, the processing methods and equipment are also updated, and the clamping method of the processing fixture is gradually replaced by air pressure and oil pressure from the original manual compression. The air is renewable and clean, and will not pollute the environment. Pneumatic clamping is more convenient and affordable than hydraulic clamping when the clamping force is not required to be high. At the same time, each processing enterprise has an air compressor to provide compressed air in a centralized manner. Compared with hydraulic clamping, it is not necessary for each machine tool to be equipped with a hydraulic station, which can save investment, save space and reduce energy consumption. It is more and more widely used in machining. Whethe...

AI Technical Summary

Problems solved by technology

It is found in the process of processing slender and strip-shaped workpieces that the existing cylinder occupies a large space during the clamping process. The large space occupied by the fixture means that the space for the workpiece to be processed is reduced, and the number of workpieces that can be clamped is reduced, thereby reducing the processing efficiency. And because there are too many types of different cylinders for the workpiece, it is necessary to purchase a variety of stroke cylinders for different strokes during use. The replaceability is not strong, and it is inconvenient to adjust the size of the cylinder between workpieces, etc.
