Description
Technical field
The present invention relates to a kind of dowel mechanism being especially applied on Automobile Welding line.
Background technology
Along with the development of Hyundai Motor technology, auto manufacturing is also just accelerating towards low labour intensity future development.Especially in weld car process, for artificial upper part, in order to reduce workman's labour intensity, increase work efficiency and all use in a large number semi-automatic equipment or man-operated mechanisms.In weld car line field, although there are some complete set of equipments, its cost is high, maintenance cost is high, can not be used widely.On the other hand, in order to improve welding efficiency, the existing mode that adopts swinging cross welding body in white, for this reason, the part manual positioning pin mechanism part that is also absolutely necessary on artificial in swinging cross sealing wire of fit applications; But existing dowel mechanism is manual operation, and adopts and be rigidly connected, this form structure complexity, precision are not high, and manual operation is while putting in place, and some is too much because of self mechanism's weight, and the phenomenon that automatically falls can occur, and makes it can not ensure normal work.
Summary of the invention
The present invention is for avoiding the existing weak point of above-mentioned prior art, and a kind of simple in structure, easy to use, easy to maintenance, four connecting rod dowel mechanisms are cheaply provided, and to increase work efficiency, ensures safe and reliable.
The design feature of the present invention's four connecting rod dowel mechanisms is:
Form hold-down support by support platform and the fixed block that is fixedly installed on support platform bottom, one side of described support platform is lateral aperture, opposite side is vertical hole, the bottom of fixed block is a horizontal pin-and-hole, guide rod is in axial sliding set in described vertical hole, the top of guide rod connects firmly alignment pin, and the bottom of guide rod is hinged on the upper end of rotation connecting rod;
In pneumatic element, cylinder rod and cylinder block are vertical setting, and the top pin joint of described cylinder rod is in the lateral aperture of support platform;
The front end of rotary handle is fixedly installed a transfer block, described transfer block is taking centre bore as rotating fulcrum, described fixed block is hinged in centre bore by rotational pin with the horizontal pin-and-hole of its bottom, the top that is positioned at centre bore is the first hinge hole, the front end that is positioned at centre bore is the second hinge hole, the bottom of rotation connecting rod is hinged in the first hinge hole by bearing pin, and cylinder block is hinged in the second hinge hole by bearing pin.
The design feature of the present invention's four connecting rod dowel mechanisms is also, in the vertical hole of described support platform, neck bush is set.
The present invention, taking cylinder as power, manually pulled rotary handle to rotatablely move in certain limit before this, provided power more afterwards by pneumatic element, drove rotation connecting rod to move down, and made alignment pin have two different positions.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, in the present invention, only need when part artificial rotary handle to drive on alignment pin and move, consume one's strength little;
2, the present invention is simple, convenient, and alignment pin can be changed alignment pin according to plate diameter;
3, the present invention can ensure result of use, can significantly reduce again equipment cost, reduce maintenance cost;
4, drives structure of the present invention can adopt domestic standard part, and framework is simple, convenient by Plate Welding simultaneously;
5, the present invention drives cylinder can be set to button control mode, makes the steady noiseless of equipment.
