Description
Technical field
The present invention relates to a kind of clamping device, particularly a kind of fore-set floating tension and compression clamping device.
Background technology
For workpiece, when carrying out some Surface Machining, it usually needs by piece-holder and fix.As carried out to workpiece
During sandblasting processing, need for workpiece fixation to carry out sandblasting operation to it, but existing clamping device troublesome poeration, clamping
Effect is bad, and complex structural designs, and number of assembling steps is loaded down with trivial details, and manufacturing cost is high.
Content of the invention
It is an object of the invention to solution above-mentioned technical problem, a kind of fore-set floating tension and compression clamping device is provided, there is knot
Structure is simple, the good feature of easy to assembly, easily operated and clamping effect.
For solving above-mentioned technical problem, present invention employs a kind of fore-set floating tension and compression clamping device, including pedestal, folder
Pawl, push rod and screw rod, wherein, described pedestal lower end level is provided with through hole, is provided with back-moving spring in described through hole, and described jaw is
The middle part of two and described jaw is hinged with the bearing set by described pedestal both sides respectively, the two ends of described back-moving spring respectively with
The lower end of described jaw is fixedly connected or mounts, and between described push rod and described pedestal, level is slidably matched, described push rod located at
The top of described back-moving spring, one end of described push rod is offseted with jaw described in side, and the other end is offseted with described screw rod, described
The threadeding with jaw described in opposite side of screw rod, described screw rod is provided with handle.
Further, in technique scheme, described pedestal upper end is provided with supporting table.
Further, in technique scheme, for the ease of installing, the two ends of described back-moving spring are mounted on described respectively
On bearing pin set by jaw lower end.
Further, in technique scheme, in order to reduce the frictional force between push rod and pedestal it is ensured that push rod movement
Smoothness, the middle part of described push rod is provided with cannelure, and between the two ends of this push rod and described pedestal, level is slidably matched.
The present invention is had the advantage that：By the operation to screw rod, screw rod pushes away to side propelling extrusion push rod, push rod
Move this side jaw, make jaw deflect the clamping realized to workpiece side, after jaw is to Workpiece clamping, the position due to jaw is protected
Hold motionless, now, then screw screw rod, screw drive opposite side jaw to a certain degree deflects, until this side jaw is realized to workpiece
The clamping of opposite side, workpiece is completely clamped, and the self-locking performance of screw rod is strong simultaneously, persistently need not give power, just enable to workpiece
Fastening, clamping effect is good, and the design structure is simple, easy to assembly and easily operated.
Brief description
Fig. 1 is the structural representation of the present invention.
Wherein：Pedestal 1；Jaw 2；Push rod 3；Screw rod 4；Through hole 5；Supporting table 6；Back-moving spring 7；Bearing 8；Bearing pin 9；Annular
Groove 10；Handle 11；Workpiece 12.
Specific embodiment
The present invention is further illustrated below in conjunction with the accompanying drawings.
As shown in figure 1, the present invention provides a kind of fore-set floating tension and compression clamping device, including pedestal 1, jaw 2, push rod 3 and
Screw rod 4, wherein, pedestal 1 lower end level is provided with through hole 5, and pedestal 1 upper end is provided with supporting table 6, is provided with back-moving spring 7 in through hole 5,
Jaw 2 is that the middle part of two and jaw 2 is hinged with the bearing 8 set by pedestal 1 both sides respectively, the two ends of back-moving spring 7 respectively with
The lower end of jaw 2 is fixedly connected or mounts, for the ease of installing it is preferred that the two ends of back-moving spring 7 are mounted on jaw 2 respectively
On bearing pin 9 set by lower end, between push rod 3 and pedestal 1, level is slidably matched, in order to reduce the friction between push rod 3 and pedestal 1
It is ensured that the smoothness of push rod 3 movement, the middle part of push rod 3 is provided with cannelure 10 to power, level between the two ends of this push rod 3 and pedestal 1
It is slidably matched, push rod 3 is offseted with side jaw 2 located at the top of back-moving spring 7, one end of push rod 3, the other end and screw rod 4 phase
Support, the threadeding with opposite side jaw 2 of screw rod 4, screw rod 4 is provided with handle 11.
Workpiece 12 is placed in supporting table 6, screws screw rod 4 afterwards, screw rod 4 promotes push rod 3 to a lateral movement, and push rod 3 pushes away
Move this side jaw 2 to swing, the bare terminal end of this side jaw 2 realizes the clamping to workpiece 12, continues afterwards to screw screw rod 4, due to
The motionless state in jaw 2 holding position of push rod 3 contact, screw rod 4 drives the swing of jaw 2 threaded therewith, and realizing should
The clamping to workpiece 12 opposite side for the side jaw 2, now workpiece 12 be in complete clamped condition；Reversely screw screw rod 4, screw rod afterwards
4 first drive jaw 2 threaded therewith to separate with workpiece 12, afterwards coordinate back-moving spring 7 contractility, push rod 3 power by
Fade mistake when, realize reset to jaw 2, workpiece 12 is released.
The specification and drawings of the present invention are considered as illustrative and not restrictive, on the basis of the present invention, ability
Field technique personnel are according to disclosed technology contents it is not necessary to performing creative labour just can be made to some of them technical characteristic
Some are replaced and deform, all within the scope of the present invention.
