Abstract
The utility model relates to a structure of an actuator, which is composed of a connecting force arm, a driving bracket, a crank arm, a three-shaft connecting frame, a bracket main body, a spring shield, a compression spring, a spring catch bowl and a bolt pull rod, wherein the connecting force arm, the driving bracket, the crank arm and the three-shaft connecting frame are connected into a connecting rod driving mechanism with the bracket main body through a positioning shaft; the spring shield, the compression spring, the spring catch bowl and the bolt pull rod form a spring energy storage mechanism. The actuator can freely adjust operating force according to requirements; the operating force is less than or equal to 20 kg; the installation and the use are simple and convenient. The service life of the actuator reaches more than 10 myriad times, and has no maintenance cost and no pollution. The utility model can be widely used for turning over side breast boards of an automobile and side turnover boards of a wing opening type box vehicle, and can replace a hydraulic system for lifting power.
Description
Affiliated technical field
The utility model relates to a kind of servo-unit structure.Belong to mechanical field.
Background technology
At present, the connection structure of trailer lorry compartment backplate and cabin floor is a hinge, because panel sheeting is long and heavy, open and close is all required great effort very much; Though the servo-unit structure that has hydraulic efficiency pressure system to use as lifting power, but hydraulic efficiency pressure system is because the restriction in packing seal life-span and the complexity of operating system and power unit, in use need the periodical maintenance maintenance, if misoperation also can cause the damage of related elements, often produce very big maintenance cost.
Summary of the invention
In order to overcome the deficiency of existing design, the utility model provides a kind of servo-unit structure.
The technical scheme that its technical matters that solves the utility model adopts is:
The utility model by connect the arm of force, transmission bracket, crank arm, three shaft holders, rack body, spring compressor, compression spring, spring catch bowl, bolt draw bar form; Connect the arm of force, transmission bracket, crank arm, three shaft holders are connected to become a jointed gear unit by fix shaft and rack body, spring compressor, compression spring, spring catch bowl, bolt draw bar are formed a spring energy-storage mechanism, compression spring is arranged in the spring compressor, compression spring is enclosed within on the bolt draw bar, and the spring catch bowl is pressed in an end of compression spring and is fixed on the bolt draw bar by nut.
Servo-unit occupation mode and working process explanation:
This servo-unit uses to be had trip shaft (as hinge) and is finishing the comparison situation of difficult by manpower.Earlier with the rack body of servo-unit by being bolted on the upset main body fixed beam, will connect the arm of force again and pass through bolt with the main body of overturning; When the motion of upset main body, make the power of spring energy-storage mechanism medi-spring be converted into actual operating effort and reach the labour-saving purpose by connecting rod mechanism.And can come the size of controlling spring strength as required by regulating bolt draw bar.
The beneficial effects of the utility model are simple in structure, and following advantage is arranged:
1. this work-saving device can freely be adjusted operating effort as required, operating effort≤20kg, and install and use simple and convenient.
2. this servo-unit can reach more than 100,000 times and the service-free cost service life, and is pollution-free.
3. can be widely used in the upset of automobile side breast board, wing opening type box van rollover plate, and can use as lifting power by the replacement liquid pressing system.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model constructional drawing.
The specific embodiment
Embodiment: in Fig. 1, connect the arm of force 1, transmission bracket 10,9, three shaft holders 8 of cranking arm, rack body 3, spring compressor 4, compression spring 5, spring catch bowl 7, bolt draw bar 6 compositions; Connecting the arm of force 1 is connected with transmission bracket 10 by fix shaft, porosely in the middle of the transmission bracket 10 9 be connected with cranking arm by fix shaft, its other end is porose to be connected with rack body 3 by fix shaft, 9 other ends of cranking arm are porose to be connected with three shaft holders 8 by fix shaft, three shaft holders 8 are connected with rack body 3 by fix shaft, the other end of three shaft holders 8 is connected with bolt draw bar 6 by fix shaft, there are the connection transmission bracket 10 of symmetry and the hole of three shaft holders 8 in the both sides of rack body 3, rack body 3 connects spring compressor 4, compression spring 5 is arranged in the spring compressor 4, compression spring 5 is enclosed within on the bolt draw bar 6, spring catch bowl 7 is pressed in an end of compression spring 5 and is fixed on the bolt draw bar 6 by nut, connect the arm of force 1, transmission bracket 10, crank arm 9, three shaft holders 8 are connected to become a jointed gear unit, spring compressor 4 by fix shaft and rack body 3, compression spring 5, spring catch bowl 7, bolt draw bar 6 is formed a spring energy-storage mechanism.
When being used in the upset of wing opening type box van rollover plate 11, connecting the arm of force 1 and captive joint with turnover panel 11, upset main body fixed mount 2 is captiveed joint with car bottom plate with rack body 3.
Before not using this servo-unit, (high by 900, the upset of weight 100～120kg) needs two people's operations and difficulty relatively to turnover panel, uses behind this product a people (operating effort≤20kg) that can easily overturn.
