Abstract
Problem to be solved in the utility model is: provide a kind of electric pushrod outer tube solved the problem, comprise outer tube and electric pushrod main body, push rod, guide rail and conduit is mainly provided with in described main body, described push rod is along guide rail axial motion, conduit is provided with outside described guide rail, described outer tube is provided with lubricating cup, and described lubricating cup runs through outer tube; Fastener is provided with between described outer tube and main body.The beneficial effects of the utility model are: 1. add lubricating cup, can add lubricating oil at any time, improve overall mechanical performance; 2. the increase of fastener, maintains the increase of overall construction intensity, and structure made of copper also contributes to heat radiation.
Description
Technical field
The utility model relates to electric pushrod technical field, particularly relates to a kind of electric pushrod outer tube.
Background technology
Electric pushrod, English name Linear Actuator, also known as push-rod electric machine, electric cylinder and linear actuators.The power-jdriven gear of electric pushrod to be a kind of by the converting rotary motion of motor the be straight reciprocating motion of push rod.Can be used for using as execution machinery, to realize far distance controlled, centralized control or automatically to control in various simple or complicated technological process.
Be mainly used in electric bed for medical purpose, Electric sofa, electronic exhibition booth elevating lever, electric industrial jacking system, camera frame, projector, wedding celebration system.
Electric pushrod is made up of drive motors, reduction gearing, screw rod, nut, guide pin bushing, push rod, slide, spring, outer tube and turbine, fine motion control switch etc.
Electric pushrod is a kind of novel electric operator, and electric pushrod, primarily of a kind of novel linear actuator of mechanism's compositions such as motor, push rod and control device, can realize far distance controlled, centralized control.Electric pushrod makes back and forth movement in certain limit stroke, and general electric pushrod standard stroke exists, 100,150,200,250,300,350,400mm, and special stroke also can be customized according to the design of different application conditional request.Electric pushrod can design the electric pushrod of different thrust according to different application load, its maximum thrust general can reach 6000N, no-load running speed is 4mm ~ 35mm/s, and electric pushrod for power source, is straight reciprocating motion the convert rotational motion of motor with 24V/12V direct current permanent magnet motor.Promote one group of linkage to complete the switch operatings such as air door, valve, gate, baffle plate.Adopt electric pushrod not only can reduce as actuator and adopt compressed air source unit needed for pneumatic actuator and auxiliary equipment, also can reduce the weight of actuator.Pneumatic actuator all needs certain air pressure in whole controlling run process, although can adopt the amplifier etc. that consumption is little, accumulate over a long period, air consumption is still huge.Adopt electric pushrod actuator, when changing control aperture, need power supply, just can no longer power when reaching required aperture, therefore from energy-conservation, there is obvious power saving advantages in electric pushrod actuator than pneumatic actuator.Be applicable to remote operation and be widely used in the keying, material handling, flow control etc. of the mechanism such as air door, valve, gate of the departments such as electric power, chemical industry, metallurgy, mine, light industry, traffic, boats and ships.Now replaced the automatics of mechanism's hand, hydraulic valve, reduction gearing mechanism with it by increasing department.
In prior art, there is following technological deficiency: 1. electric pushrod inside lacks corresponding lubricating structure, each lubricating oil that adds all needs electric pushrod to take apart, is lubricated, very inconvenient for field operation; 2. outer tube lacks corresponding fastening structure to the connection before main body, and Long-Time Service easily loosens.
Utility model content
Problem to be solved in the utility model is: provide a kind of electric pushrod outer tube solved the problem.
The technical solution of the utility model is as follows: a kind of electric pushrod outer tube, comprising outer tube is positioned at outside electric pushrod main body, push rod, guide rail and conduit is mainly provided with in described main body, described push rod is along guide rail axial motion, conduit is provided with outside described guide rail, it is characterized in that: described outer tube is provided with lubricating cup, described lubricating cup runs through outer tube; Fastener is provided with between described outer tube and main body.
Further, described fastener is fastening annulus.
Further again, described fastener is fastening annulus made of copper.
Further, described lubricating cup runs through outer tube, the space after running through and conduit UNICOM.
Further, described guide rail has oil nozzle, for lubrication between push rod and guide rail.
The beneficial effects of the utility model are: 1. add lubricating cup, can add lubricating oil at any time, improve overall mechanical performance; 2. the increase of fastener, maintains the increase of overall construction intensity, and structure made of copper also contributes to heat radiation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, lubricating cup, 2, fastener,
3, guide rail, 4, guide pin bushing,
5, push rod, 6, outer tube,
7, oil nozzle.
Embodiment
Below in conjunction with accompanying drawing, brief description is made to embodiment of the present utility model.
As shown in Figure 1, a kind of electric pushrod outer tube, comprises outer tube 6 and is positioned at outside electric pushrod main body, be mainly provided with push rod 5, guide rail 3 and conduit 4 in described main body, and described push rod 5, along guide rail 3 axial motion, is provided with conduit 4 outside described guide rail 3.For the ease of lubrication, described outer tube 6 is provided with lubricating cup 1, and described lubricating cup 1 runs through outer tube 6, and the space after running through and conduit 4 UNICOM, described guide rail 3 has oil nozzle 7, for lubrication between push rod 5 and guide rail 3.Be provided with fastener 2 between described outer tube 6 and main body, described fastener 2 is fastening annulus made of copper.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
