The invention has the beneficial effects as follows: the multi link positioning and clamping mechanism size of the present invention is less, simple in construction, it is simple to operation.
Accompanying drawing explanation
Fig. 1 is the multi link positioning and clamping mechanism structural representation of the present invention.
Detailed description of the invention
As shown in Figure 1, the invention discloses a kind of multi link positioning and clamping mechanism, including drive mechanism, connection seat 3, link gear, first connecting rod 10, second connecting rod 7, clamping block 8, pressing plate 9, described link gear includes third connecting rod 11, hinge 5, described drive mechanism is connected with described third connecting rod 11, and described third connecting rod 11 can be driven to move, described connection seat 3 is hinged with described third connecting rod 11 and described second connecting rod 7 respectively, described hinge 5 is hinged with described third connecting rod 11 and described second connecting rod 7 respectively, described first connecting rod 10 is hinged with described second connecting rod 7 and described pressing plate 9 respectively, described pressing plate 9 is hinged with described second connecting rod 7, described clamping block 8 is hinged with described second connecting rod 7, described clamping block 8 is used for being matched for clamping tightly part with described pressing plate 9.
This multi link positioning and clamping mechanism includes that the first limited block 6, described first limited block 6 are fixedly linked with described second connecting rod 7.
This multi link positioning and clamping mechanism also includes that mounting seat 2, described connection seat 3 are fixedly linked with described mounting seat 2.
Described drive mechanism is arranged in described mounting seat 2.
Described drive mechanism is cylinder 1, and the piston rod of described cylinder 1 is connected with described third connecting rod 11.
This multi link positioning and clamping mechanism also includes the second limited block 4, described second limited block 4 is two, one of them second limited block 4 is connected with described second connecting rod 7, and another second limited block 4 is connected with described mounting seat 2, and two the second limited blocks 4 carry out coordinating spacing.
During work, cylinder 1 shrinks and drives third connecting rod 11, and third connecting rod 11 rotates around the fixing pin joint on connection seat 3, drives first connecting rod 10 to move with hinge 5 simultaneously.First connecting rod 10 and hinge 5 do plane motion, and while first connecting rod 10 motion, band dynamic pressure plate 9 moves, and pressing plate 9 rotates around the pin joint of second connecting rod 7；Second connecting rod 7 is driven to move while hinge 5 motion, second connecting rod 7 rotates around the fixing pin joint of connection seat 3, and second connecting rod 7 drives clamping block 8 to move while rotating so that clamping block 8 departs from part, second connecting rod 7 band dynamic pressure plate 9 the most again moves so that the amplitude of pressing plate 9 motion is bigger.After cylinder 1 shrinks completely, fixture stop motion.The process that fixture is closed is contrary with this process, fits when moving to the second limited block 4, and when hinge 5 is fitted with the first limited block 6, fixture is limited, arrives operating position, and part is clamped.
Owing to fixture assembling link is more, for convenient processing and manufacture, it is impossible to requiring the highest tolerance, the clamping block 8 of end and pressing plate 9 can accumulate certain mismachining tolerance.In order to eliminate this error, clamping block 8 installs the adjustment pad of 3mm thickness additional, it is simple to adjust position during three coordinate measurements.First connecting rod 10 is the adjustable link of adjustable length structure, can be adjusted the rotational angle of pressing plate 9, it is simple to eliminate the error that pressing plate 9 is accumulated.
The multi link positioning and clamping mechanism of the present invention has the advantage that 1. compact conformations are light, is conducive to alleviating main clamp weight.Main clamp is lighter, can improve its speed of service, thus favourable to improving productive temp.2. design reduces a cylinder, decreases the compressed air consumption of a cylinder, be conducive to saving the energy.The most each part processing and manufacturing is conventional precision, does not increase manufacture difficulty, uses adjustable mode to eliminate cumulative error.The most each part all uses common material, low cost of manufacture.5. pressing plate 9 moves with clamping block 8 simultaneously, opens simultaneously or simultaneously clamps on, and is prevented effectively from fixture and interferes with part.6., by each pin joint relative to the appropriate design of position, after clamp, i.e. it is in self-locking position, good stability.7. use the adjustable link of adjustable length structure, the pass angle degree of regulation pressing plate, eliminate foozle.
Above content is to combine concrete preferred implementation further description made for the present invention, it is impossible to assert the present invention be embodied as be confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, it is also possible to make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
