Description
Technical field
The present invention relates to a kind of dowel mechanism that especially is applied on the automobile sealing wire.
Background technology
Along with the development of Hyundai Motor technology, auto manufacturing is also just quickening to develop towards low labour intensity direction.Especially in the weld car process,,, increase work efficiency and all use semi-automatic equipment or man-operated mechanisms in a large number in order to reduce working strength of workers to part in the manual work.In weld car line field, though some complete set of equipments are arranged, 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 also is absolutely necessary in the manual work of fit applications in the swinging cross sealing wire; But existing dowel mechanism is manual operation, and adopts and to be rigidly connected, and this form structure is complicated, precision is not high, and manual operation is when putting in place, and some is too much because of self mechanism's weight, and the phenomenon that falls automatically can take place, and makes it can not guarantee operate as normal.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology weak point, and a kind of simple in structure, easy to use, easy to maintenance, four connecting rod dowel mechanisms cheaply are provided, and to increase work efficiency, guarantees safe and reliable.
The design feature of the present invention's four connecting rod dowel mechanisms is:
Constitute hold-down support by support platform and the fixed block that is fixedly installed on the support platform bottom; One side of said support platform is a lateral aperture; Opposite side is vertical hole, and the bottom of fixed block is a horizontal pin-and-hole, and guide rod in axial sliding is set in said 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;
Cylinder rod and cylinder block are vertical setting in the pneumatic element, and the top pin joint of said cylinder rod is in the lateral aperture of support platform;
The front end of rotary handle fixedly installs a switching piece; Said switching piece is to be rotating fulcrum with the centre bore; Said fixed block is hinged in the centre bore through rotational pin with the horizontal pin-and-hole of its bottom, and the top that is positioned at centre bore is first hinge hole, and the front end that is positioned at centre bore is second hinge hole; The bottom of rotation connecting rod is hinged in first hinge hole through bearing pin, and cylinder block is hinged in second hinge hole through bearing pin.
The design feature of the present invention's four connecting rod dowel mechanisms also is in the horizontal pin-and-hole of said support platform, neck bush to be set.
The present invention is power with the cylinder, manually spurs rotary handle before this and rotatablely moves in certain limit, by pneumatic element power is provided again afterwards, and the driven in rotation connecting rod moves down, and makes alignment pin that two different positions arranged.
Compared with present technology, beneficial effect of the present invention is embodied in:
1, only need artificial rotary handle to drive on the alignment pin during the last part of the present invention and move, it is little to consume one's strength;
2, the present invention is simple, convenient, and alignment pin can be changed alignment pin according to the plate diameter;
3, the present invention can guarantee result of use, can significantly reduce equipment cost again, reduce maintenance cost;
4, Drive Structure of the present invention can adopt the domestic standard part, and framework is simple, convenient by the steel plate welding simultaneously;
5, the present invention drives cylinder and can be set to the button control mode, makes the steady noiseless of equipment.
