Abstract
The invention discloses a clamping device for a thin plate workpiece. The clamping device for the thin plate workpiece comprises a cylinder, clamps, a connecting rod and an expansion bolt mainly made of an elastic metal material. The clamps include the first clamp and the second clamp. The lower end of the expansion bolt is fixedly connected with the first clamp after penetrating through a round pipe. The lower end of the round pipe is fixedly connected with the cylinder through the connecting rod. The cylinder is fixedly connected with the first clamp. A through hole matched with the round pipe is formed in the second clamp. The diameter of the upper end of the expansion bolt is larger than that of the round pipe. Meanwhile, at least one open part extending in the axial direction is formed in the upper end of the expansion bolt. According to the clamping device for the thin plate workpiece, a traditional fixing way for clamping of thin plate products is changed, the workpeice is directly fixed to the clamps instead of being fixed to a machining plate, in this way, the workpiece can be fixed more effectively, and the phenomena that the workpiece is crushed and the size of the workpiece is not stable can be effectively avoided during machining.
Description
Technical field
The present invention relates to a kind of clamping device of sheet type workpiece.
Background technology
In casting industry, the aluminium silicon member thin plate clamping of processing is a difficult problem, and solving the topmost method of product clamping problem at present has two kinds: one is increase by processing plate, is placed wherein by workpiece, is then fixed on fixture and processes; Another kind is exactly use holder after workpiece surrounding increases pressure point, then processes.But a kind of front method not only increases the difficulty that cost also increases clamping workpiece.Another kind method too increases cost, and built on the sand, does not tackle the problem at its root.
Summary of the invention
For the deficiencies in the prior art, the object of this invention is to provide one and can reduce piece-holder difficulty, clamping is stable, the clamping device of cost-effective sheet type workpiece.
For achieving the above object, present invention employs following technical scheme:
A kind of clamping device of sheet type workpiece, comprise cylinder, fixture, connecting rod and the swell fixture formed primarily of elastic metallic material, described fixture comprises the first fixture and is fixedly connected with the first fixture through after a pipe with swell fixture lower end described in the second fixture, described pipe lower end is fixedly connected with cylinder by connecting rod, described cylinder is fixedly connected with the first fixture, and described second fixture is provided with the through hole coordinated with described pipe, the diameter of described swell fixture upper end is greater than the diameter of described pipe, described swell fixture upper end is provided with at least one opening portion extended vertically simultaneously.
As the further optimization of such scheme, described swell fixture upper end has the tapering of 95 ~ 100 °.
As the further optimization of such scheme, the upper end of described swell fixture is provided with and extends vertically and through the gap, two or more opening portion in axle center, make swell fixture have higher elasticity, more durable.
As the further optimization of such scheme, between described swell fixture bottom and pipe, be also provided with the snap device cooperatively interacted.
Beneficial effect main manifestations of the present invention is: change the fixed form that light sheet products clamping is traditional, be fixed on processing plate by workpiece and change into and be directly fixed on fixture, workpiece is more effectively fixed, effectively can avoid weighing wounded and size wild effect to workpiece generation in process.

Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, more specific detail is done to the present invention.
Embodiment 1
As shown in Figures 3 and 4, a kind of clamping device of sheet type workpiece, the swell fixture 3 comprising cylinder 5, fixture, connecting rod 6 and formed primarily of elastic metallic material, described fixture comprises the first fixture 8 and the second fixture 7, described swell fixture 3 lower end is fixedly connected with the first fixture 8 through after a pipe 4, described pipe 4 lower end is fixedly connected with cylinder 5 by connecting rod 6, described cylinder 5 is fixedly connected with the first fixture 8, and described second fixture 7 is provided with the through hole coordinated with described pipe 4, the diameter of described swell fixture 3 upper end is greater than the diameter of described pipe 4.Described swell fixture 3 upper end has the tapering of 97 °.The upper end of described swell fixture 3 is provided with and extends vertically and through the gap, two or more opening portion in axle center.The snap device cooperatively interacted also is provided with, in order to avoid pipe 4 departs from swell fixture 3 between described swell fixture 3 bottom and pipe 4.
Traditional clamping workpiece mechanism is locked on processing plate 1 by key screw workpiece, then be fixed on fixture 2, as shown in Figure 1 and Figure 2, before processing, processing plate 1 is fixed on fixture 2, add man-hour due to workpiece being fixed with screw, being easy to processing discontinuity like this causes flatness not high, and size is unstable.In addition, can produce aluminium bits in lock screw process, aluminium bits are easy to remain between processing plate 1 and workpiece, cause product leaves weighing wounded; And along with the increase of access times, processing plate can be out of shape gradually, causes processing work size unstable, can not effectively play a role.
The clamping device of the present embodiment, pull pipe 4 downward by cylinder 5, reduce the constraint of many swell fixtures 3 gradually, swell fixture 3 is due to the tapering of itself, upper end is thicker than lower end, therefore naturally swelling, produces the buckle power to the second fixture 7, distance between two fixtures reduces with the motion of cylinder 5, the piece-holder between fixture is lived.This process does not produce metal fillings, and the workpiece avoiding metal fillings to cause weighs wounded; Do not need to process plate, improve the production efficiency of product, save cost.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of application claims.
