Abstract
The utility model relates to an electric push rod which comprises a motor, a speed reducer, an external casing and an internal casing. The motor, the speed reducer, a screw and a thrust nut are essentially positioned inside the external casing wherein the motor is connected with the screw by the speed reducer. The thrust nut, sleeve positioned at the screw, has a fit connection with the thread in the screw. At the same time, the thrust nut is connected with the rear end of the internal casing and positioned inside the external casing. The front end of the external casing is equipped with the end cover used for sealing and supporting the internal casing. The motor utilizes a positioning post for a positioning and a fixation and is connected with the screw by a planet gear of speed reducer. The thrust nut and a connecting casing is sleeved into the screw and positioned in a fixation casing positioned in the external casing. The utility model has the advantages of simple manufacture and logical structure and is characterized in that the electric push rod can operate more convenient and position accurately. Because a thrust bearing is used, the utility model can effectively avoid a force on the screw exerted by the thrust nut and prevent the screw from damage.
Description
Technical field
The utility model relates to a kind of electric pushrod, particularly relates to a kind of electric pushrod that can reciprocating stroke.
Background technology
In all kinds of dynamo-electric complete set of equipments and automatic control equipment thereof, extensively adopt electric pushrod as the Direct Travel actuator of realizing the reciprocating sliding requirement.Existing electric pushrod adopts gear graduation, and the transmission of monofilament bar is stopped using as overload protection to transship float axle bed and limit switch, and stroke own is non-adjustable, as the user stroke is had requirement, requires that then travel switch externally is installed and could regulate and control reciprocating stroke.Chinese patent discloses the screw thread electric pushrod of application number 01247656.0, this electric pushrod, motor is connected with last pole socket, motor output shaft is connected with screw mandrel, and screw mandrel has the main transmission screw thread to cooperate with the push rod nut, and the push rod nut is positioned at pole socket down, following pole socket is one with last pole socket or is connected, in the following pole socket long key is arranged, the push rod nut has axial groove and long key movingly, and pole socket was connected with coupling head under stretched out the lower end of promotion nut.But this screw thread electric pushrod in use, because the push rod nut is also given power of screw mandrel, makes screw mandrel that the trend of motion backward be arranged, and bearing is damaged easily; Directly carry out transmission by bearing between motor and the screw mandrel, the speed of transmission is identical with motor also, can not satisfy multiple needs.
Summary of the invention
The purpose of this utility model is in order to solve above-mentioned existing problem, and provide a kind of rational in infrastructure, make simple electric pushrod, this electric pushrod also have accurate positioning, can retaining effect, can satisfy multiple different requirement.
The utility model is achieved through the following technical solutions above-mentioned purpose.This electric pushrod, comprise motor, decelerator, outer tube and inner sleeve, motor, decelerator, screw mandrel and thrust nut mainly are installed in outer tube, motor is connected with screw mandrel by decelerator, be set with thrust nut on the screw mandrel, thrust nut is connected with the threaded engagement that is on the screw mandrel, and thrust nut is connected with the rear end of inner sleeve, be placed in the outer tube, the front end of outer tube is provided with the end cap that is used to seal and support inner sleeve.
Described motor positions fixing by reference column, motor is connected with screw mandrel by planet wheel decelerator; Suit thrust bearing and adapter sleeve on the screw mandrel, thrust bearing and adapter sleeve are installed in the fixed cover, and fixed cover is installed in the outer tube.
The front end of outer tube is fixedly connected by bolt and the end cap that supports inner sleeve, and the rear end of inner sleeve is connected with thrust nut by bolt.Motor rear end can also be provided with dust cap, to keep cleaning, the health of motor, guarantees that motor effectively turns round.The rear end of described outer tube is connected with tail and connects, and the front end of inner sleeve is connected with head and connects.
This electric pushrod preferably uses the motor that has braking ring, can make the push rod location more accurate like this.
The beneficial effects of the utility model: this electric pushrod, compared with former electric pushrod, make simply, rational in infrastructure, make the electric pushrod operation convenient, the location is accurately; Owing to used thrust bearing,, kept screw mandrel not to be damaged so can effectively avoid thrust nut to award the active force of screw mandrel; Motor is connected by decelerator with screw mandrel, can select different decelerator dealing with various requirements for use.

The accompanying drawing identifier declaration
The 1-outer tube, the 2-inner sleeve, the 3-tail connects, and the 4-head connects, 5-motor, 6-reference column, 7-decelerator, 8-thrust bearing, 9-screw mandrel, 10-thrust nut, 11-bolt, 12-dust cap, 13-end cap, 14-fixed cover.
Embodiment
The utility model will be further described below in conjunction with specific embodiment.
As shown in Figure 1, this electric pushrod comprises motor 5, decelerator 7, outer tube 1 and inner sleeve 2, and the rear end of described outer tube 1 is connected with tail and connects 3, and the front end of inner sleeve 2 is connected with head and connects 4.The motor 5, decelerator 7, screw mandrel 9 and the thrust nut 10 that have braking ring mainly are installed in outer tube 1, and motor 5 positions fixing by reference column 6, and motor 5 rear ends are provided with dust cap 12.Motor 5 is connected with screw mandrel 9 by planet wheel decelerator 7, be set with thrust nut 10 on the screw mandrel 9, thrust nut 10 is connected with the threaded engagement that is on the screw mandrel 9, thrust nut 10 is connected by bolt 11 with the rear end of inner sleeve 2, be placed in the outer tube 1, the front end of outer tube 1 is provided with the end cap 13 that is used to seal and support inner sleeve 2, and the front end of outer tube 1 is fixedly connected by four bolts 11 and end cap 13.The end suit thrust bearing 8 and the adapter sleeve of screw mandrel 9, thrust bearing 8 and adapter sleeve are installed in the fixed cover 14, and fixed cover 14 is installed in the outer tube 1.Adapter sleeve is in the drawings for being installed in the fixed cover 14 left side of thrust bearing 8.
During use, open motor 5, motor 5 drives screw mandrel 9 and is rotated by planet wheel decelerator 7, thrust bearing 8, the thrust nut 10 of screw mandrel 9 by matching with it, rotation is become rectilinear motion, promote inner sleeve 2 and travel forward, also travel forward thereby make head connect 4.After motion arrives certain position, disable motor 5, because the braking ring effect, motor 5 stops the rotation very soon, head connects 4 and also no longer travels forward.Change the rotation direction of motor 5, can make head connect 4 motions in the opposite direction.
