Operation principle of the present invention is: when cylinder rod stretches out, cylinder connector promotes step locating piece and travels forward, and step locating piece switches to high face by bottom surface and contacts with limited block, and sliding panel moves right with press-loading device entirety, and Rectangular Spring is compacted; When cylinder rod stretches out, cylinder connector pulls step locating piece to think rear motion, step locating piece switches to bottom surface by high face and contacts with limited block, sliding panel is moved to the left with press-loading device entirety, Rectangular Spring release portion pressure, but still in impaction state, ensure that press-loading device can not slide to the right.
Compared with public technology, there is following advantage in the present invention:
1, the little displacement high accuracy of the present invention mechanism can realize the definite position of automatic precision of pressure head, and the jackshaft of realizing each kind gearbox can coaxially press-fit, and has ensured to press-fit quality;
2, the present invention supports to ensure final position by Rectangular Spring, can not reveal and change position because of compressed air or Hydraulic Station, reliable and stable;
3, the step locating piece difference in height in the present invention ensures by processing, the position that only need adjust a kind of product, and another one position is also just definite, and install and adjust is convenient;
4, the present invention is by a cylinder switching position, and a Rectangular Spring ensures position, and cost is low, simple in structure, easy to maintenance, safe and reliable;
5, the present invention is by the extended and retracted position of sensor sensing step locating piece, and position difference is large, and approach switch signal accurately and reliably;
6, structure of the present invention is also applicable to tighten the position automatic switchover of the parts such as axle, code reader.
