Hydraulic adjusting device with hidden adjusting support

Abstract

The invention relates to the technical field of hydraulic execution elements, in particular to a hydraulic adjusting device with a hidden adjusting support, which comprises an external cylinder body, a first electromagnetic valve, a second electromagnetic valve and a third electromagnetic valve. According to the hydraulic adjusting device with the hidden type adjusting support, the combined piston composed of the outer piston and the inner piston is inserted into the outer cylinder body, the piston control pipe with the built-in hidden type telescopic adjusting support is fixedly connected to the side wall of the combined piston, and electromagnetic valves at different positions are controlled; therefore, the external piston and the internal piston can be controlled respectively, the adjusting control modes are more diversified, and operation is easy and convenient. And the electromagnetic valves adopt external design, so that connection of an external control circuit is facilitated, later-stage detection and maintenance are also facilitated, and later-stage use cost is reduced.

Description

technical field [0001] The invention relates to the technical field of hydraulic actuators, in particular to a hydraulic adjustment device with a hidden adjustment bracket. Background technique [0002] The hydraulic rod is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). It has simple structure and reliable operation. When using it to realize reciprocating motion, the reduction device can be omitted, and there is no transmission gap, and the movement is stable, so it is widely used in various mechanical hydraulic systems. The output force of the hydraulic cylinder is proportional to the effective area of ​​the piston and the pressure difference on both sides; the hydraulic cylinder is basically composed of a cylinder barrel and a cylinder head, a piston and a piston rod, a sealing device, a buffer device and an exhaust device. Buffers and exhausts depend on the application, others are es...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: In order to solve the problems existing in the above-mentioned background technology, an improved hydraulic adjustment device with a hidden adjustment bracket is provided to solve the problem that the hydraulic rods currently on the market have a simple structure and a single internal structure and control mode. Limitation, the structure of the top of the hydraulic rod is fixed and cannot be adjusted, because the contact area is relatively small, and the hydraulic pistons are mostly circular structures, resulting in very limited stability at the assembly end and a relatively small range of installation applications
