Description
Technical field:
The utility model belongs to power hydraulic pressure and promotes technical field.
Background technique:
Electro hydraulicthruster is widely used in power hydraulic pressure braking technology field, mainly is to utilize electric power to drive the structure action by hydraulic transmission.Present electro hydraulicthruster is made of motor, cylinder body, impeller, piston, slideway, two push rods etc.Motor is put on being exposed, and motor reel is hollow, and slideway is housed on the motor shaft, and slideway is connected with square shaft, and square shaft one end is installed impeller, and impeller is contained on the piston support.When motor was switched on, motor shaft drives slideway and square shaft rotates, thereby impeller is rotated, impeller produces centrifugal force, under action of centrifugal force, thereby cylinder body produces oil pressure promotion piston and two push rods move upward, and finishes pushing action under the effect of two push rods.After the motor outage, push rod and piston are back to the origin-location under external force, finish homing action.This structure is two push rod beam structures, and two push rod parallelism are difficult to control, influence its thrust and actuation time, and power consumption is bigger, and noise is higher; And parts interchangeability is poor, and clamping stagnation can not in time reset easily, easily causes industrial accident.Because the narrow limitation of its structure, the motor of adapted is an externally-arranged type, need adjust the motor perpendicularity during installation and terminal box exposes unprotect, very easily damages motor.
The model utility content:
The purpose of this utility model provides and a kind ofly operates steadily, energy consumption is less, noise is lower, the non-damageable electro hydraulicthruster of motor.
In order to realize above-mentioned purpose, the utility model comprises: connecting rod, push rod, cylinder body, piston, impeller, the Oil Guide dish, slide blocks, end cap, motor casing, motor, sliding axle, motor by the motor casing sealing and fixing in the bottom, the top of motor casing is tightly connected by end cap and cylinder body, connecting rod is fixed on the push rod top, the bottom of push rod penetrates into cylinder interior by the seal ring of cylinder interior, it is hollow that the rotatingshaft of motor is set to half, rotatingshaft penetrates into cylinder interior through the oil seal of end cap inside, the rotary shaft end headgear has slide blocks, pass slide blocks and in hollow rotatingshaft, be provided with sliding axle, be provided with the Oil Guide dish on the top of sliding axle, utilize tightening nut to be set with impeller at the upper tip of Oil Guide dish top sliding axle, upper impeller is a piston, fixedlys connected with the push rod lower end in the piston upper end.
Described cylinder side wall top is provided with tests the whelk bolt, is convenient to understand at any time hydraulic oil liquid level height.
When work, motor is switched on like this, and motor is by slide blocks and the rotation of sliding axle impeller, impeller produces centrifugal force, and the oil pressure of piston bottom is raise, and promotes piston and moves upward, rise rapidly thereby drive push rod and connecting rod, finish rated travel and keep thrust.Motor outage back impeller no longer rotates, and push rod and piston descend rapidly under external force, get back to initial position, finish pushing course.Solved that two push rod parallelism are not high, clamping stagnation, the major defect that can not reset and easily cause the accident; Motor is built-in installation, has solved because of wiring terminal to damage or liquid enters the failure problems that motor cavity causes motor to burn out.Have characteristics such as operate steadily, energy consumption is less, noise is lower, and motor is not fragile.
Description of drawings:
Fig. 1 is an internal structure schematic representation of the present utility model.
Embodiment:
As shown in Figure 1, the utility model comprises: connecting rod 1, push rod 2, cylinder body 4, piston 5, impeller 7, Oil Guide dish 8, slide blocks 9, end cap 11, motor casing 12, motor 13, sliding axle 17.In the bottom, the two ends of motor are by rolling bearing 14 support fixation by motor casing 12 sealing and fixing for motor 13.The top of motor casing utilizes connecting bolt 10 and cylinder body 4 to be tightly connected by end cap 11.Connecting rod 1 is fixed on push rod 2 tops, and connecting rod is provided with attachment hole 22, is used for and being connected of push mechanism.The bottom of push rod 2 penetrates into cylinder interior by the seal ring 20 of cylinder interior, is provided with circlip 21 and sliding bearing 19 respectively in the top and the bottom of seal ring 20, to guarantee the tight property of lubrication and seal of oil cylinder when push rod is flexible.It is hollow that the rotatingshaft 15 of motor 13 is set to half side, rotatingshaft 15 penetrates into cylinder interior through the oil seal 16 of end cap inside, rotatingshaft 15 terminations are with slide blocks 9, pass slide blocks and in hollow rotatingshaft 15, be provided with sliding axle 17, sliding axle is set to square and cooperatively interacts with rotatingshaft is hollow, can drive sliding axle and rotate also and can slide when motor rotates.Be provided with Oil Guide dish 8 on the top of sliding axle 17, utilize tightening nut 6 to be set with impeller 7 at the upper tip of Oil Guide dish top sliding axle, impeller 7 tops are pistons 5, fixedly connected with push rod 2 lower ends in the piston upper end.Be provided with refueling bolt 3 on cylinder body top, be used to inject hydraulic oil.Be provided with on cylinder side wall top and test whelk bolt 18, be convenient to understand at any time hydraulic oil liquid level height.The big I of specification of the present utility model is made series product according to thrust size needs.
