Abstract
A cascade stage multi-cylinder actuating mechanism comprises cylinders, piston bodies and springs. Each cylinder comprises a cylinder body, a spring installation base arranged on the inner wall of the cylinder body and an air inlet located in the lateral wall of the cylinder body. The piston body comprises a push rod portion and at least two seal portions. The seal portions are sealed with the inner wall of the cylinder body in a sliding mode, the seal portions are arranged in parallel, the push rod portion is perpendicular to the seal portions, the top end of the push rod portion is fixed to the seal portion on a top layer, and the lower end of the push rod portion penetrates out of the bottom end of the cylinder. One end of each spring is fixed to the corresponding spring installation base, and the other end of the spring is in butt joint with the seal portion below the spring installation base. According to the cascade stage multi-cylinder actuating mechanism, multi-cascade springs are arranged to act on the multiple seal portions, so that push force of the cylinders is remarkably increased under the condition that the size and weight of the device are not increased. The largest push force of the actuating mechanism of the cascade stage multi-cylinder actuating mechanism is two to three times that of a single cylinder actuating mechanism of the same model.
Description
technical field:
The utility model relates to industrial automatic control field, particularly a kind of tandem multi-cylinder actuator.
background technique:
In a lot of fields such as electric power, oil, chemical industry, require pneumatic control valve can close rapidly in the situation that dying source, and existing straight journey cylinder major part is single cylinder, along with the volume of the increase cylinder of thrust increases, weight increases, especially single-acting straight journey cylinder, bulking value is all very heavy.
summary of the invention:
Given this, be necessary to design that a kind of volume is little, lightweight, the tandem multi-cylinder actuator of high thrust.
One tandem multi-cylinder actuator, comprising: cylinder, piston body, spring; Cylinder comprises: cylinder body, be arranged on inboard wall of cylinder block spring mounting seat, be positioned at the suction port of cylinder side wall; Piston body comprises: push rod portion and at least two sealed departments; Sealed department and inboard wall of cylinder block slipper seal, parallel between sealed department, vertical seal portion of push rod portion and push rod portion top are fixed on top layer sealed department, and push rod subordinate end passes from cylinder body bottom; Spring one end is fixed on spring mounting seat, and the other end connects with the sealed department that is positioned at spring mounting seat below, and the space that the spring mounting seat that sealed department is adjacent with its below is separated is air chamber, and suction port is positioned on the cylinder side wall of air chamber corresponding part.
Preferably, sealed department is two, and that air chamber correspondingly has is two-layer, suction port has two covers.
Preferably, top spring mounting seat is fixed on cylinder body top, two-level spring fitting seat be fixed on the cylinder wall under top layer sealed department and top spring mounting seat and two-level spring fitting seat between distance be at least the stroke of piston body, be provided with through hole in the position of the corresponding push rod of two-level spring fitting seat portion and pass for push rod portion.
Preferably, cylinder body end face is circle, and the number of springs on every grade of spring mounting seat is 3 ~ 8, and spring circumferential arrangement on every grade of spring mounting seat.
Thereby the utility model has enlarged markedly cylinder thrust by multi-layer spring action is set on multiple sealed departments in the situation that not increasing equipment volume weight, and the maximum thrust of the utility model actuator can be 2 ~ 3 times of same model single cylinder actuator.
accompanying drawing explanation:
Accompanying drawing 1 is the structural representation of the tandem multi-cylinder actuator of a width preferred embodiments.
In figure: sealed department 21, push rod portion 22, cylinder body 11, spring mounting seat 12, suction port 13, bottom 111, spring 3, air chamber 14, through hole 121.
embodiment:
As shown in Figure 1, a kind of tandem multi-cylinder actuator, comprising: cylinder, piston body, spring; Cylinder comprises: cylinder body 11, be arranged on inboard wall of cylinder block spring mounting seat 12, be positioned at the suction port 13 of cylinder side wall; Piston body comprises: push rod portion 22 and at least two sealed departments 21; Sealed department 21 and cylinder body 11 inwall slipper seals, parallel between sealed department 21,22 vertical seal portions 21 of push rod portion and push rod portion 22 tops are fixed on top layer sealed department 21, and push rod portion 22 lower ends pass from cylinder body 11 bottoms 111; Spring 3 one end are fixed on spring mounting seat 12, the other end connects with the sealed department 21 that is positioned at spring mounting seat 12 belows, the space that the spring mounting seat 12 that sealed department 21 is adjacent with its below is separated is air chamber 14, and suction port 13 is positioned on cylinder body 11 sidewalls of air chamber 14 corresponding parts.
In the present embodiment, sealed department 21 is two, and that air chamber 14 correspondingly has is two-layer, suction port 13 has two covers.
In the present embodiment, top spring mounting seat 12 is fixed on cylinder body 11 tops, two-level spring fitting seat 12 is fixed on distance on cylinder body 11 walls under top layer sealed department 21 and between top spring mounting seat 12 and two-level spring fitting seat 12 and is at least the stroke of piston body, and the position of 12 corresponding push rod portions 22 being installed at two-level spring is provided with through hole 121 and passes for push rod portions 22.
In the present embodiment, cylinder body 11 end faces are circle, and spring 3 quantity on every grade of spring mounting seat 12 are 3 ~ 8, and spring 3 circumferential arrangement on every grade of spring mounting seat 12.
