Abstract
The utility model discloses a bidirectional automatic centering, positioning and pressing mechanism which comprises a support saddle, wherein two pressing arms are movably arranged inside the upper end of the support saddle, and the upper ends of the two pressing arms extend out of the upper end of the support saddle; compress blocks are respectively arranged on one side surfaces in the opposite direction of the upper ends of pressing arms respectively, a power mechanism is additionally arranged, and the power mechanism can drive the two pressing arms to move inside the support saddle and enables the two pressing arms to do folding and unfolding actions so as to enable the two compress blocks of the two pressing arms to be far away from and close to and compress a to-be-positioned workpiece. Therefore, the bidirectional automatic centering, positioning and pressing mechanism provided by the utility model has the comprehensive advantages of simple structure, reliability and stability in quality, relatively lower cost and the like, can achieve positioning and compressing within narrow space, and has higher circulating beats.
Description
Technical field
The utility model relates to a kind of Automobile Welding hold-down mechanism, relates in particular to a kind of two-way automatic centering positioning compression mechanism.
Background technology
At present, at the automobile body-in-white welding field, the very little place that can have living space, longeron zone needs positioning compression, and traditional method is to adopt two to drive cylinders, after the positioning turning of a side puts in place, then compresses the mechanism of opposite side.The positioning compression of this routine exists and occupies the defectives such as the space is large, structure is loaded down with trivial details, unstable, and then affects size and the outward appearance of welding quality and the rear parts of welding, causes vehicle body vision and the problems such as all kinds of assembling and security performance.
Summary of the invention
In order to overcome defects, the utility model provides a kind of two-way automatic centering positioning compression mechanism, can realize the positioning compression of small space.
The utility model for the technical scheme that solves its technical problem and adopt is:
A kind of two-way automatic centering positioning compression mechanism comprises bearing, is movably equipped with two pressure arms in described bearing upper end, and stretch out outside described bearing upper end this two pressure arm upper end; Be respectively equipped with a compact heap on a side in opposite directions, upper end of described two pressure arms, separately be provided with an actuating unit, thus this actuating unit can drive described two pressure arms in described bearing movable and described two pressure arms are done open two compact heaps that make this two pressure arm with folding away from near and compress workpiece to be positioned.
As further improvement of the utility model, thereby described actuating unit can drive described two pressure arms in described bearing movable and described two pressure arms are done open two compact heaps that make this two pressure arm with folding away from near and the structure that compresses workpiece to be positioned be: described actuating unit is a lift cylinder, described pressure arm middle part is provided with a kidney slot, separately be provided with a fixed axis in bearing, this fixed axis activity is set in described kidney slot, and the piston rod of described lift cylinder is flexibly connected the lower end of described pressure arm by a movable axis.
As further improvement of the utility model, the piston rod upper end of the described lift cylinder contiguous block that is connected, this contiguous block is flexibly connected the lower end of described pressure arm by movable axis.
As further improvement of the utility model, the upper end of described two pressure arms is respectively arc in opposite directions.
As further improvement of the utility model, be provided with the adjustment pad between described compact heap and described pressure arm.
The beneficial effects of the utility model are: this structure promotes pressure arm by lift cylinder and moves along the kidney slot planned course, realize that opening with pressing of compact heap move, have simple in structure, reliable in quality is stable, the comprehensive advantages such as cost is relatively low can realize the positioning compression of small space, and are reliable and stable, cost is lower, and the circulation beat is higher.

The specific embodiment
Below in conjunction with accompanying drawing, a kind of preferred embodiment of the present utility model is described.
as shown in Fig. 1, Fig. 2, Fig. 3 A, Fig. 3 B and Fig. 3 C, a kind of two-way automatic centering positioning compression mechanism comprises bearing 1, is movably equipped with two pressure arms 2 in described bearing upper end, and stretch out outside described bearing upper end this two pressure arm upper end, be respectively equipped with a compact heap 3 on a side in opposite directions, upper end of described two pressure arms, separately be provided with an actuating unit, thereby this actuating unit can drive described two pressure arms in described bearing movable and described two pressure arms are done open two compact heaps that make this two pressure arm with folding away from near and compress workpiece 10 to be positioned, before use, by actuating unit make two pressure arms open namely two compact heaps away from, can be placed in workpiece to be positioned between two compact heaps this moment, then start actuating unit, drive two pressure arms and fold namely two compact heaps near supporting respectively workpiece to be positioned, thereby play the positioning compression effect.
preferably, thereby described actuating unit can drive described two pressure arms in described bearing movable and described two pressure arms are done open two compact heaps that make this two pressure arm with folding away from near and the structure that compresses workpiece to be positioned be: described actuating unit is a lift cylinder 4, described pressure arm middle part is provided with a kidney slot 5, separately be provided with a fixed axis 6 in bearing, this fixed axis activity is set in described kidney slot, the piston rod of described lift cylinder is flexibly connected the lower end of described pressure arm by a movable axis 7, during use, the elevating movement of the piston rod by cylinder, driving pressure arm moves up and down simultaneously, due to pressure arm lower end and piston rod flexible connection, and pressure arm middle part is provided with a kidney slot, separately there is a fixed axis activity to be set in this kidney slot, therefore pressure arm can only be along the orbiting motion of kidney slot setting under the elevating movement of cylinder piston rod drives, thereby realize opening and folding of two pressure arms.
Preferably, the piston rod upper end of the described lift cylinder contiguous block 8 that is connected, this contiguous block is flexibly connected the lower end of described pressure arm by movable axis.
Preferably, the upper end of described two pressure arms is respectively arc in opposite directions.
Preferably, be provided with adjustment pad 9 between described compact heap and described pressure arm.
