Abstract

The invention discloses a linkage type clamping mechanism. The linkage type clamping mechanism comprises a fixing mechanism and a clamping mechanism. The fixing mechanism comprises a base and a guide column supporting a workpiece. A circular hole is formed in the base. The guide column is arranged in the base. A first spring piece is arranged between the guide column and the base. A wedge-shaped groove opposite to the circular hole is formed in the guide column. The clamping mechanism comprises a pressing plate used for clamping the workpiece, and a bolt used for limiting the pressing plate. The bolt penetrates the pressing plate and is arranged in the base. The end, away from the base, of the bolt is sleeved and connected with a nut. A second spring piece is arranged between the pressing plate and the base. A locking pin is arranged in the pressing plate, arranged in the circular hole and opposite to the wedge-shaped groove. By means of the scheme, the problems that an existing clamp is complex in structure, tedious in operation and low in work efficiency are solved.

Description

Coordinated type clamp system
Technical field
The present invention relates to field of fixtures, be specifically related to a kind of coordinated type clamp system.
Background technology
In a broad sense, any operation in technical process, is used for rapidly, installs easily and safely the device of workpiece, all can be described as fixture.Such as weld jig, inspection jig, assembling jig, jig etc.Wherein jig is the most common, often referred to as fixture.On lathe during processing work, the dimensions reaching drawing for making the surface energy of workpiece and specify, geometry and with the technical requirements such as the relative-position error on other surfaces, workpiece must be installed before processing, clip.Fixture is made up of setting element, clamping device, tool setting induction element, indexing means, Connection Element and clamp body etc. usually.
Fixture and grip device are widely known by the people, and are widely used for manufacturing.Particularly, fixture has various reference surface and point, and parts or instrument can accurately be located.In many process, this is general to clamp member, so that these parts can keep correct juxtaposition relationship in such as punching press, riveted joint, welding, the process of pasting or solidifying.Fixture is considered to requisite parts in processing industry, and is the vitals of calculating processing cost, is also the vitals requiring that logistics is considered in process of production.The usual structure of existing fixture is more complicated, operation is more loaded down with trivial details, reduces the operating efficiency to work pieces process.
Summary of the invention
The invention is intended to provide the coordinated type clamp system that a kind of structure is simple, easy to operate, operating efficiency is high.
For achieving the above object, base case of the present invention is as follows: coordinated type clamp system, comprise fixed mechanism and clamp system, described fixed mechanism comprises pedestal and supports the guide pillar of workpiece, circular hole is provided with in described pedestal, described guide pillar is arranged in pedestal, is provided with the first spring part between described guide pillar and pedestal, and described guide pillar is provided with the wedge-shaped slot relative with circular hole; Described clamp system comprises for the pressing plate of clamping work pieces and the bolt for limiting pressing plate, described bolt is arranged in pedestal through pressing plate, described bolt is socketed with nut away from one end of pedestal, the second spring part is provided with between described pressing plate and pedestal, be provided with lock pin in described pressing plate, described lock pin is arranged in circular hole relative with wedge-shaped slot.
The principle of base case and advantage: during operation, be first positioned on guide pillar by workpiece, it is corresponding with circular hole that guide pillar is moved downward to wedge-shaped slot; Tightening nuts presses down pressing plate and moves to pedestal again, one end and the workpiece of pressing plate offset, lock pin moves to guide pillar in circular hole simultaneously, when lock pin interts in wedge-shaped slot, lock pin gives guide pillar one thrust upwards, and guide pillar and workpiece offset, and realize the clamping to workpiece with this, now the first spring part is in extended state, and the second spring part is in impaction state.When loosen nut, the second spring part promotes pressing plate to the right can unclamp workpiece, and lock pin shifts out wedge-shaped slot to the right simultaneously, and the first spring part pulls guide pillar to unclamp workpiece downwards.This programme is mainly through tightening nuts, and make pressing plate, lock pin and guide pillar produce the clamping of interlock realization to workpiece, its overall construction is simple, easy to operate, effectively raises the operating efficiency to work pieces process.
Preferred version one: based on the preferred version of scheme, one end of described platen clamp workpiece is provided with the projection of arc-shaped, by above-mentioned setting, replace Planar realization to the clamping of workpiece by projection, reduce contact area, significantly reduce the wearing and tearing to workpiece, and projection compares flat grip workpiece, impetus is more concentrated, also just better to the clamping effect of workpiece.
Preferred version two: based on the another preferred version of scheme; described bolt is also socketed with the packing ring of rubber; described packing ring is arranged between nut and pressing plate; by above-mentioned setting; packing ring has certain elasticity; the surface of protective folder pressing plate can not be subject to the wearing and tearing of nut, add the service life of pressing plate plate, effectively saved cost.
Preferred version three: based on the another preferred version of scheme, described first spring part is extension spring, by above-mentioned setting, extension spring has certain tension force, when clamping work pieces, extension spring is in extended state, when unclamping workpiece, extension spring can give guide pillar one downward pulling force, effectively decreases the time of unclamping workpiece.
Preferred version four: based on the another preferred version of scheme, described second spring part is stage clip, by above-mentioned setting, stage clip has very strong compression capability, when clamping work pieces, stage clip is in impaction state, when unclamping workpiece, stage clip can give pressing plate one thrust to the right, effectively decreases the time of unclamping workpiece.
Accompanying drawing explanation
Fig. 1 is the structural representation of coordinated type clamp system embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: pedestal 1, guide pillar 2, extension spring 3, circular hole 4, wedge-shaped slot 5, pressing plate 6, bolt 7, nut 8, lock pin 9, projection 10, stage clip 11, packing ring 12.
Embodiment is substantially as shown in Figure 1: coordinated type clamp system, comprise fixed mechanism and clamp system, fixed mechanism comprises pedestal 1 and supports the guide pillar 2 of workpiece, the right-hand member of pedestal 1 is provided with circular hole 4, guide pillar 2 is arranged in pedestal 1, be provided with extension spring 3 between guide pillar 2 and pedestal 1, in guide pillar 2, be provided with the wedge-shaped slot 5 relative with circular hole 4; Clamping framework comprises for the pressing plate 6 of clamping work pieces and the bolt 7 for limiting pressing plate 6, one end of pressing plate 6 clamping work pieces is provided with the projection 10 of arc-shaped, bolt 7 is arranged in pedestal 1 through pressing plate 6, bolt 7 is socketed with nut 8 and packing ring 12 away from one end of pedestal 1, packing ring 12 is arranged between nut 8 and pressing plate 6, be provided with stage clip 11 between pressing plate 6 and pedestal 1, be provided with lock pin 9 in pressing plate 6, lock pin 9 is arranged in circular hole 4 relative with wedge-shaped slot 5.
