Description
Technical field
The invention belongs to Machining Technology field, relate to a kind of hold down gag, be specifically related to a kind of hold down gag with auto-lock function driven by eccentric.
Background technology
When parts are carried out machining, first have to workpiece to be processed is positioned compression, the workpiece mode of stepping up conventional at present is to adopt nut bolt to coordinate to be fixed, although this mode is simple and convenient, but operator has the disadvantage in that the time used by workpiece pressing is long in use, and production efficiency is low, step up in process relatively elaborate, labor intensity is high, and automaticity is low, makes enterprise be in a disadvantageous position in the same industry is competed.Particularly with plate part, owing to its area is relatively big, single hold-down head is difficult to it is carried out good location.In common clamp system, Eccentric Clamping Mechanism is with its good auto-lock function, the enlarging function of power, and has simple in construction and the quick advantage of action.Therefore, Eccentric Clamping Mechanism obtains application widely in fixture.
Summary of the invention
The technical problem to be solved is in that for above-mentioned deficiency of the prior art, it is provided that a kind of eccentric self-locking formula hold down gag, and it is reasonable in design, simple in construction, easy to operate, self-locking property is good, has reinforcement function, reducing labor strength, production cost is low, it is simple to promote the use of.
For reaching above-mentioned purpose, the technical solution used in the present invention is: a kind of eccentric self-locking formula hold down gag, including the base plate playing fixed supporting role and for the bearing of support guide plate, it is characterised in that: also include the pressure head for workpiece pressing, for driving described pressure head to be pressed downward against the eccentric of clamping of workpieces and the back-moving spring for driving described pressure head upwards to reset；Described bearing it is installed with on the upside of described base plate, on the upside of described bearing, described guide plate slides is provided with described pressure head, multiple described back-moving spring it is provided with between described pressure head and described guide plate, fix with pole lower end on the upside of described guide plate and be connected, described pole upper end is rotationally connected with described eccentric after described pressure head, and described eccentric sidewall is installed with described driving handle.
Above-mentioned eccentric self-locking formula hold down gag, it is characterised in that: described driving handle welds or is threadably secured and is arranged on described eccentric.
Above-mentioned eccentric self-locking formula hold down gag, it is characterised in that: described pole and described eccentric are rotationally connected by bearing pin.
Above-mentioned eccentric self-locking formula hold down gag, it is characterised in that: described bearing is welded or is fixedly mounted on described base plate by screw.
Above-mentioned eccentric self-locking formula hold down gag, it is characterised in that: described guide plate is welded or is fixedly mounted on described bearing by screw.
The present invention has the advantage that compared with the prior art
(1) design of this eccentric self-locking formula hold down gag is very reasonable, and simple and compact for structure, workpiece only need to be placed on work platforms by operator, and manual depression driving handle can complete the compression to workpiece and operate, and uses very easy.
(2) this eccentric self-locking formula hold down gag adopts eccentric mechanism clamping, and self-locking property is good, safe and reliable.
(3) this eccentric self-locking formula hold down gag has reinforcement function, can significantly reduce the labor intensity of operator.
(4) this eccentric self-locking formula hold down gag production technology is simple, and requirement on machining accuracy is not high, and a lot of parts are all highly convenient for producing or buying, thus its production cost is very low, it is simple to promote the use of.
Below by drawings and Examples, the present invention is described in further detail.

Detailed description of the invention
A kind of eccentric self-locking formula hold down gag as shown in Figure 1, including the base plate 1 playing fixed supporting role and for the bearing 2 of support guide plate 8, also include the pressure head 7 for workpiece pressing 9, for driving described pressure head 7 to be pressed downward against the eccentric 5 of clamping of workpieces 9 and the back-moving spring 3 for driving described pressure head 7 upwards to reset；Described bearing 2 it is installed with on the upside of described base plate 1, slided by described guide plate 8 on the upside of described bearing 2 and be provided with described pressure head 7, multiple described back-moving spring 3 it is provided with between described pressure head 7 and described guide plate 8, fix with pole 4 lower end on the upside of described guide plate 8 and be connected, described pole 4 upper end is rotationally connected with described eccentric 5 after described pressure head 7, and described eccentric 5 sidewall is installed with described driving handle 6.
In the present embodiment, described driving handle 6 welds or is threadably secured and is arranged on described eccentric 5.
In the present embodiment, described pole 4 is rotationally connected by bearing pin with described eccentric 5.
In the present embodiment, described bearing 2 is welded or is fixedly mounted on described base plate 1 by screw.
In the present embodiment, described guide plate 8 is welded or is fixedly mounted on described bearing 2 by screw.
The work process of eccentric self-locking formula hold down gag of the present invention is: first this eccentric self-locking formula hold down gag is arranged on operating position, workpiece to be processed 9 is placed on the upside of base plate 1, eccentric 5 is rotated counterclockwise by driving handle 6, so that eccentric 5 drive ram 7 moves down and compresses workpiece to be processed 9, owing to eccentric 5 has auto-lock function, without applying driving force again after workpiece to be processed 9 is compacted, just it can be processed after compression.When workpiece to be processed 9 is processed complete after, rotate clockwise eccentric 5 by driving handle 6, eccentric 5 departs from pressure head 7 upper surface, and pressure head 7 upwards can reset under the driving of back-moving spring 3, thus unclamping the workpiece 9 machined.
The above; it it is only presently preferred embodiments of the present invention; not the present invention is imposed any restrictions, every any simple modification, change and equivalent structure transformation above example made according to the technology of the present invention essence, all still fall within the protection domain of technical solution of the present invention.
