Abstract
The utility model relates to a mechanical actuating mechanism, in particular to a fault-free high-precision actuating mechanism. The fault-free high-precision actuating mechanism comprises a machine body (1), a shaft lever (2), an upper fault-free high-precision component (3), a lower fault-free high-precision component (4) and an upper end cover (5); the upper fault-free high-precision component (3) and the lower fault-free high-precision component (4) are respectively installed at the upper part and the lower part of the shaft lever (2) to form a shaft lever component; the shaft lever component is assembled on the machine body (1) and fixed on the machine body (1) via the upper end cover (5) of the machine body; and both the upper fault-free high-precision component (3) and the lower fault-free high-precision component (4) are symmetrically assembled on both sides of the shaft lever (2), and piston mechanisms are respectively assembled on both sides of the shaft lever (2). The fault-free high-precision actuating mechanism can be used for various rotating valves such as ball valves, butterfly valves, eccentric rotary valves, plug valves, air valves and the like, can be used for assembling various air source accessories such as positioning devices, solenoid valves and the like, and also can be applied to the automatic control device.
Description
Technical field
The utility model relates to a kind of mechanical actuating mechanism, particularly relates to a kind of actuator of fault-free high-precision configuration, is used for rotating the class valve: ball valve, butterfly valve, camflex valve, stopcock and automatic control device.
Background technique
Existing actuator: as axle sleeve, can produce local damage to axle and axle sleeve, cause breaking down and the shortening in working life, also can produce local damage when precision is not high, increase frictional force, produce heat and then influence delivery efficiency, and making the material requirements strictness, cost increases.
Summary of the invention
The purpose of this utility model is to provide a kind of fault-free high-precision actuator, this mechanism adopts the fault-free high-precision configuration, the power of local damage is reduced to 1/tens, will effectively avoids damage, make the life-span of actuator improve several times, reach trouble-free state.
The purpose of this utility model is achieved through the following technical solutions:
The high-precision actuator of a kind of fault-free, this actuator includes body, axostylus axostyle, top fault-free highi degree of accuracy member, bottom fault-free highi degree of accuracy member, upper end cap, the top fault-free highi degree of accuracy member of packing on the axostylus axostyle, the bottom fault-free highi degree of accuracy member of packing into down constitutes shaft member; Shaft member is attached on the body, and the upper end cap of body is fixed on shaft member on the body.
The high-precision actuator of described a kind of fault-free, its described top fault-free highi degree of accuracy member, bottom fault-free highi degree of accuracy member be the both sides that are installed in axostylus axostyle of symmetry all, and the both sides of axostylus axostyle are equiped with piston mechanism.
Advantage of the present utility model and effect are:
1, this fault-free high-precision configuration actuator is owing to adopt the fault-free high-precision configuration, the power of local damage reduced (can be reduced to 1/tens), and local damage is effectively spread, and reaches the trouble-free state that uses.
2, this fault-free high-precision configuration actuator makes the life-span of actuator improve (can improve several times) because damage has been carried out effectively avoiding.
3, this fault-free high-precision configuration actuator has carried out reducing (can be reduced to 1/tens) owing to adopt the fault-free high-precision configuration with frictional force, and control accuracy improves significantly.Delivery efficiency is improved, and has improved output torque.
Description of drawings
Fig. 1 is an overall structure schematic representation of the present utility model.
Embodiment
With reference to the accompanying drawings the utility model is elaborated.
Among the figure: 1 body, 2 axostylus axostyles, 3 top fault-free highi degree of accuracy members, 4 bottom fault-free highi degree of accuracy members, 5 upper end caps.
The top fault-free highi degree of accuracy member 3 of packing on the axostylus axostyle 2, the bottom fault-free highi degree of accuracy member 4 of packing into down forms shaft member; Shaft member is encased on the body 1, and the upper end cap 5 with body is fixed on shaft member on the body 1 at last, and when axostylus axostyle 2 rotated, the fault-free high-precision configuration had just worked.
During use, load pressurized air at cylinder, make cylinder piston drive piston rod and move, piston rod drives the axle connecting lever and drives axostylus axostyle 2 rotations, forms output torque.This fault-free high-precision configuration actuator can be used for rotating the class valve: ball valve, butterfly valve, camflex valve, stopcock, air door etc., source of the gas annexes such as equipped positioning work piece, solenoid valve can be used in automatic control device.
That top fault-free highi degree of accuracy member 3, the material of bottom fault-free highi degree of accuracy member 4 can adopt is corrosion-resistant, high-abrasive material or heat treatment material.
