Abstract
The utility model provides an electric push rod which comprises a motor reducer (1), a connecting block (2), a guide flat key (3), a lead screw (4), a cylinder body (5), a shaft sleeve (6), a guide sleeve (7) and a plug (8), wherein the motor reducer (1) is connected with the cylinder body (5) by a flange, the connecting block (2) and the shaft sleeve (6) form a welding combination body (9) and synchronously move, the welding combination body (9) and the cylinder body (5) are connected by the guide flat key (3) and can axially move, the welding combination body (9) and the lead screw (4) are connected in a threaded way, the lead screw (4) is driven to rotate by the rotation of the motor reducer (1) and then drives the welding combination body (9) to move along the axial direction, the guide flat key (3) is fixed with the cylinder body (5) by screws, the guide sleeve (7) is connected with the cylinder body (5) in a threaded way, and the plug (8) is connected with the shaft sleeve (6) in a threaded way and moves with the shaft sleeve (6) together. In the electric push rod, due to that the lead screw and the motor reducer are integrated into a whole, a coupling joint, a coupling joint shock absorber, an interval cylinder and the like are saved, and therefore, a lot of spaces and materials are saved, so that the cost is lowered, and the structure is simplified.
Description
Technical field
The utility model is a kind of power-jdriven gear that rotatablely moving of motor is changed into the straight reciprocating motion of push rod.Can be used in the various simple or complicated technological processes, use as carrying out machinery.
Technical background
In all kinds of motor complete set of equipments and automatic control equipment thereof, extensively adopt electric pushrod as the craspedodrome actuator of realizing the reciprocating sliding requirement.At present, its motor reducer of known electric pushrod drives the leading screw rotation through coupling, key connection, pin connection etc.Its structure is too complicated, cost is higher, volume is big, assembling is complicated.
Summary of the invention
In order to overcome deficiencies such as existing electric pushrod complex structure, cost height, assembling complexity, it is a kind of electric pushrod of one that the utility model provides a kind of leading screw and motor reducer.Thereby make this electric pushrod possess series of advantages such as designs simplification, cost reduction.
The utility model adopts following technical scheme for achieving the above object:
Motor reducer of the present utility model and leading screw are one, motor reducer is connected by flange with cylindrical shell, contiguous block and axle sleeve be soldering group fit they be synchronized with the movement, soldering group is fit to be to be endwisely slipped by realizing of being connected of dive key with cylindrical shell, soldering group is fit with leading screw be threaded, dive key and cylindrical shell be by screw, guide pin bushing with cylindrical shell for be threaded, plug moves with axle sleeve for being threaded with axle sleeve.
Thereby motor reducer drive leading screw rotates leading screw and drives contiguous block along axial motion, thereby and contiguous block and sleeve are the axial motions of the fit realization of soldering group leading screw drive sleeve.
When motor just changes,, finish the push of electric pushrod through above-mentioned transmission; When motor reverses, finish the process that retracts of motor.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Embodiment
This electric pushrod comprises as shown in Figure 1: motor reducer 1, contiguous block 2, dive key 3, leading screw 4, cylindrical shell 5, axle sleeve 6, guide pin bushing 7, plug 8, soldering group zoarium 9.Wherein motor reducer 1 is one with leading screw 4, motor reducer 1 and cylindrical shell 5 are connected by flange, they are synchronized with the movement for soldering group fit 9 for contiguous block 2 and axle sleeve 6, soldering group fit 9 and cylindrical shell 5 are to be endwisely slipped by realizing of being connected of dive key 3, soldering group fit 9 with leading screw 4 be threaded, dive key 3 is by screw with cylindrical shell 5, guide pin bushing 7 with cylindrical shell 5 for be threaded, plug 8 moves with soldering group zoarium 9 for being threaded with axle sleeve 6.
Leading screw 4 stretches out through motor reducer 1 as shown in Figure 2, and soldering group fit 9 is threaded with leading screw 4, rotates leading screws 4 and drives soldering group zoariums 9 along axial motion thereby motor reducer 1 drives leading screw 4, thereby realize 6 axial motions of leading screw 4 drive axle sleeves.
When electric pushrod was worked, through above-mentioned transmission, motor just changeed, and finishes the push of electric pushrod; Motor reverses, and finishes the process that retracts of motor.
Claims (1)
- An electric pushrod it comprise: motor reducer (1), contiguous block (2), dive key (3), leading screw (4), cylindrical shell (5), axle sleeve (6), guide pin bushing (7), plug (8), soldering group zoarium (9) is characterized in that described leading screw (4) and motor reducer (1) are one.
