Description
Technical field
This utility model relates to a kind of machining equipment, particularly relates to a kind of work holder.
Background technology
Plastics have good mechanical property, are widely used in machinery, electronics, automobile and other industries, and plastics part typically uses injection mo(u)lding, but there may be the phenomenons such as cast gate, overlap, burr after Workpiece shaping, needs are cleared up, and existing general employing bolt and nut fixes workpiece to be processed, needs hands to twist bolt and regulates, waste time and energy, work efficiency is low, and clamps built on the sand, causes workpiece to loosen, make to clear up not thorough, affect workpiece quality.
Utility model content
This utility model overcomes the deficiencies in the prior art, it is provided that the work holder of a kind of simple in construction.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of work holder, the casing and the part that including base, are arranged on described base stretch into the holder in described casing, described holder includes train wheel bridge, lower plate, described train wheel bridge and lower plate are by bearing pin pin joint, it is provided with torsion spring on described bearing pin, one end of described torsion spring abuts with described train wheel bridge, the other end abuts with described lower plate, it is provided with air bag between described train wheel bridge and the inner roof wall of casing, described air bag connects air pump, and described air bag is provided with venting plug.
In one preferred embodiment of this utility model, work holder farther includes to be provided with on described base cylinder, and the cylinder arm of described cylinder connects push pedal.
In one preferred embodiment of this utility model, it is L-shaped that work holder farther includes described push pedal.
In one preferred embodiment of this utility model, work holder farther includes to be provided with groove on described train wheel bridge, two side plates arranged along the longitudinal direction it are fixed with at described groove, being fixed with two flanges arranged along the longitudinal direction on described lower plate, described bearing pin passes described flange, side plate.
In one preferred embodiment of this utility model, work holder farther includes described train wheel bridge and stretches into the part of described casing and be inclined upwardly setting.
This utility model solves defect present in background technology, this utility model simple in construction, easy to use, unclamping between train wheel bridge and lower plate is realized by the pressure of air bag, it is easy to the placement of the workpiece of different-thickness, air bag deflation just can clamp the workpiece of different-thickness, applied widely, and chucking power is firm, safe and reliable.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the front view that the clamp parts of preferred embodiment of the present utility model stretches in casing；
Fig. 2 is the train wheel bridge side view with lower plate pin joint of preferred embodiment of the present utility model；
Fig. 3 is the side view arranging cylinder on the base of preferred embodiment of the present utility model.
Detailed description of the invention
Being described in further detail this utility model presently in connection with drawings and Examples, these accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is described the most in a schematic way, and therefore it only shows the composition relevant with this utility model.
As shown in Figure 1 and Figure 2, a kind of work holder, the casing 4 and the part that including base 2, are arranged on base 2 stretch into the holder in casing 4, and holder includes train wheel bridge 6, lower plate 8, and train wheel bridge 6 and lower plate 8 are by bearing pin 10 pin joint, torsion spring 12 it is provided with on bearing pin 10, one end of torsion spring 12 abuts with train wheel bridge 6, and the other end abuts with lower plate 8, is provided with air bag 14 between the inner roof wall of train wheel bridge 8 and casing 4, air bag 14 connects air pump 16, and air bag 14 is provided with venting plug 18.Preferably lower plate 8 is fixed with casing 4, it is simple to train wheel bridge 6 moves relative to lower plate 8 is smooth and easy.
As it is shown on figure 3, be provided with cylinder 20 on the preferred base of this utility model 2, the cylinder arm 22 of cylinder 20 connects push pedal 24.Further preferably push pedal 24 is L-shaped, fixed next reference position, it is simple to be placed in push pedal 24 by plastics part to be processed.
Being provided with groove 26 on the preferred train wheel bridge of this utility model 6, be fixed with two side plates arranged along the longitudinal direction 28 at groove 26, lower plate 8 is fixed with two flanges arranged along the longitudinal direction 30, bearing pin 10 is through flange 30, side plate 28.
In order to improve the distance that train wheel bridge 6 moves to lower plate 8, thus improving the distance opened between train wheel bridge 6 and lower plate 8, it is simple to be suitable for the clamping of the plastics part of different-thickness, the preferred train wheel bridge of this utility model 6 stretches into the part 32 of casing 4 and is inclined upwardly setting.
This utility model is in use, plastics part to be processed is placed in push pedal 24, air pump 16 inflates to air bag 14, owing to the upper part of air bag 14 is stopped by casing 4 roof, air bag 14 expands downwards and train wheel bridge 6 stretches into the part 32 of casing 4 produces downward thrust, another part of train wheel bridge 6 deviates from lower plate 8 and moves, open between train wheel bridge 6 and lower plate 8, cylinder 20 starts, push pedal 24 is driven to drive the nose motion of plastics part between train wheel bridge 6 and lower plate 8 by cylinder arm 22, open venting plug 18, air bag 14 is made to exit, train wheel bridge 6 stretches into the part 32 of casing 4 and moves upward, plastics part is clamped by train wheel bridge 6 with lower plate 8.
Above according to desirable embodiment of the present utility model for enlightening, by above-mentioned description, related personnel can carry out various change and amendment completely in the range of without departing from this utility model technological thought.The content that the technical scope of this utility model is not limited in description, it is necessary to determine technical scope according to right.
