Abstract
The invention discloses a bidirectional automatic centering, positioning and pressing mechanism, which comprises a support, wherein two pressing arms are movably arranged in the upper end of the support; the upper ends of the two pressing arms extend out of the upper end of the support; a pressing block is arranged on one of the opposite side faces of the upper ends of the two pressing arms; and a power mechanism is also provided and can drive the two pressing arms to move in the support and make the two pressing arms be folded and unfolded, so that the two pressing blocks of the two pressing arms can get away from and get close to and press a workpiece to be positioned. The bidirectional automatic centering, positioning and pressing mechanism has the comprehensive advantages of simple structure, reliable and stable quality, relatively low cost and the like; positioning and pressing in a narrow space can be realized; the mechanism is stable, reliable and relatively low in cost; and the circulation byte is relatively high.
Description
Technical field
The present invention relates to a kind of Automobile Welding hold-down mechanism, relate 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, compresses the mechanism of opposite side again.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 invention provides a kind of two-way automatic centering positioning compression mechanism, can realize the positioning compression of small space.
The present invention 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 the described bearing upper end this two pressure arms upper end; Side in opposite directions, upper end at described two pressure arms is respectively equipped with a compact heap, other is 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 a further improvement on the present invention, 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, in bearing, be provided with in addition a fixed axis, this fixed axis activity is set in the 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 a further improvement on the present invention, the contiguous block that is connected on the piston rod of described lift cylinder, this contiguous block is flexibly connected the lower end of described pressure arm by movable axis.
As a further improvement on the present invention, the upper end of described two pressure arms is respectively arc in opposite directions.
As a further improvement on the present invention, between described compact heap and described pressure arm, be provided with the adjustment pad.
The invention has the beneficial effects as follows: 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 preferred embodiment of the present invention is described.
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 the described bearing upper end this two pressure arms upper end; Side in opposite directions, upper end at described two pressure arms is respectively equipped with a compact heap 3, other is 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 the use, by actuating unit make two pressure arms open namely two compact heaps away from, can place 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, in bearing, be provided with in addition a fixed axis 6, this fixed axis activity is set in the 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, because pressure arm lower end and piston rod are flexibly connected, and the pressure arm middle part is provided with a kidney slot, other has a fixed axis activity to be set in this kidney slot, therefore the orbiting motion that under the elevating movement of cylinder piston rod drives, can only set along kidney slot of pressure arm, thus realize opening and folding of two pressure arms.
Preferably, the contiguous block 8 that is connected on the piston rod of described lift cylinder, 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, between described compact heap and described pressure arm, be provided with adjustment pad 9.
