Description

A kind of miniature oil cylinder of superhigh pressure sealing

Technical field

This utility model relates to oil cylinder technical field, is specially a kind of miniature oil cylinder of superhigh pressure sealing。

Background technology

Oil cylinder and hydraulic cylinder, hydraulic cylinder is the linear motion type executive component that the pressure reduction on power output and piston effective area and both sides thereof is directly proportional。Its function is to convert hydraulic energy to mechanical energy。The input quantity of hydraulic cylinder is flow and the pressure of fluid, and output is point-to-point speed and power。The piston of hydraulic cylinder can complete straight reciprocating motion, and the straight-line displacement of output is limited。Hydraulic cylinder is the energy conversion device of the mechanical energy that hydraulic energy is converted to linear reciprocating motion。Hydraulic cylinder is substantially made up of cylinder barrel and cylinder cap, piston and piston rod, sealing device, buffer unit and exhaust apparatus。Buffer unit and exhaust apparatus are depending on concrete application scenario, and other devices are then essential。Recently as the high speed development of China's science and technology, various machines emerge in an endless stream, and they are all inseparable with oil cylinder。

By contrast, the drawback of the conventional oil cylinder of tradition just becomes day by day to highlight；First the big multiplex steel plate combination of cylinder body of tradition oil cylinder, radiating effect is poor, when working long hours, it is easily generated high temperature and oil cylinder is caused fatal damage, affect the service life of oil cylinder, bulky, poor air-tightness, has a strong impact on the installing space with machinery equipment, need our solve。

Summary of the invention

The purpose of this utility model is in that to provide a kind of miniature oil cylinder of superhigh pressure sealing, to solve that the radiating effect that proposes in above-mentioned background technology is poor, bulky and the problem such as poor air-tightness。

For achieving the above object, this utility model provides following technical scheme: a kind of miniature oil cylinder of superhigh pressure sealing, including cylinder body, charged piston, the first groove, the second groove, oil-in, internal layer silica gel ring and outer layer silica gel ring, described charged piston is arranged on the inside of cylinder body, and charged piston is provided with the first groove and the second groove, the right shell of described cylinder body is provided with oil-in with charged piston opposite position place, the inwall of described oil-in is provided with outer layer silica gel ring, and the inwall of outer layer silica gel ring is provided with internal layer silica gel ring。

Preferably, four edges of described cylinder body are provided with chamfering, and the physical dimension of four chamferings is identical。

Preferably, described charged piston is column structure。

Preferably, described first groove and the second groove are cirque structure, and the width of the first groove is more than the width of the second groove。

Preferably, the inside grooves of described first groove and the second groove is all filled with silica gel protection layer。

Compared with prior art, the beneficial effects of the utility model are: the miniature cylinder structure of this superhigh pressure sealing is scientific and reasonable, safe and convenient to use, charged piston adopts beryllium copper material, rapid heat dissipation, effectively solves the high temperature that is that produce because of intrinsic pressure big in cylinder and causes damaging, the problem of service life reduction。Seal position and adopt the design of import silica gel material, double; two cushion rubber, rational in infrastructure, good seal performance。Occupy little space, under work pressurized state, it is possible to reach 800kg/cm2, efficiently solve that existing oil cylinder volume is big, the present situation of impact and machinery equipment installing space, use convenient efficiently。

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments。Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection。

Refer to Fig. 1-2, this utility model provides a kind of technical scheme: a kind of miniature oil cylinder of superhigh pressure sealing, including cylinder body 1, charged piston 2, first groove 3, second groove 4, oil-in 5, internal layer silica gel ring 6 and outer layer silica gel ring 7, charged piston 2 is arranged on the inside of cylinder body 1, and charged piston 2 is provided with the first groove 3 and the second groove 4, first groove 3 and the second groove 4 are cirque structure, and first the width of groove 3 more than the width of the second groove 4, the inside grooves of the first groove 3 and the second groove 4 is all filled with silica gel protection layer, charged piston 2 is column structure, the right shell of cylinder body 1 is provided with oil-in 5 with charged piston 2 opposite position place, four edges of cylinder body 1 are provided with chamfering 8, and the physical dimension of four chamferings 8 is identical, the inwall of oil-in 5 is provided with outer layer silica gel ring 7, and the inwall of outer layer silica gel ring 7 is provided with internal layer silica gel ring 6。

Operation principle: this utility model is safe and convenient to use, does not change the occupation mode of tradition oil cylinder, directly can be grasped by most staff during practical operation；In process, charged piston 2 adopts beryllium copper material, rapid heat dissipation, effectively solves the high temperature that is that produce because of intrinsic pressure big in cylinder and causes damaging, the problem of service life reduction。The groove of first groove the 3, second groove 4 and oil-in 5 seals position and all adopts import silica gel material, double; two cushion rubber to design, rational in infrastructure, good seal performance。Occupy little space, under work pressurized state, it is possible to reach 800kg/cm2, efficiently solve that existing oil cylinder volume is big, the present situation of impact and machinery equipment installing space, use convenient efficiently。
