Abstract
The utility model belongs to the technical field of machining and particularly relates to a clamping device used for machining hard and brittle flakelet products. The clamping device includes a vacuum generator and a vacuum platform; a vacuum gas passage of the vacuum platform is communicated with the vacuum generator; a groove which is matched with a workpiece to be machined in appearance is formed in the vacuum platform, and a rubber blanket which is even in thickness and matched with the groove in boundary dimension is fixedly pasted at the bottom of the groove; a plurality of gas guide holes are evenly formed in the rubber blanket, and the gas guide holes penetrate through the bottom of the groove and are communicated with the vacuum gas passage of the vacuum platform. According to the clamping device, attaching degree between the workpiece to be machined and a clamp is improved, strong adsorption force can be obtained, and firm clamping can be achieved. Furthermore, the clamping device is simple in structure, high in efficiency and capable of greatly improving machining yield and machining quality of the hard and brittle flakelet products.
Description
Technical field
The utility model belongs to Machining Technology field, particularly a kind of clamping device of hard fragility flakelet series products processing use.
Background technology
Along with consumer is more and more higher to the requirement of product appearance, and the application of special material on electronic product such as shell, usually need some hard fragility flakelets to carry out processing patterns, these thin slices are little, the thin thickness of size not only, and material fragility is large, add careless slightly will stressedly damage in man-hour, cause processing yield lower, quality is difficult to guarantee.The factor of product processing quality and yield that affects is except lathe itself and processing technology, and installation way and clamping tool also play vital effect.The clamping of traditional plate class, sheet class workpiece generally adopts vacuum cup as clamping tool, being about to workpiece is positioned on the platform with vacuum way, effect by vacuum generator by absorption of workpieces on platform, the contact site that this kind of fixture can guarantee workpiece and clamp body is stressed evenly, thereby obtain higher machining accuracy, be specially adapted to the clamping of large-scale sheet type workpiece.But this fixture is for hard fragility flakelet series products, because lamina dimensions is too small, make the contact area of itself and clamp body also very little, and clamp body and thin slice are hard material, during absorption, be easy between the two produce gap and inhale not tightly, adding man-hour, can produce under external force loosening dislocation, finally cause processing to be scrapped.In order to solve flakelet series products, add and be difficult to fixing problem man-hour, some adds industry and commerce and adopts stickum flakelet is directly glued and process on table top, the shortcoming of this installation way is that the viscous force of stickum cannot guarantee, too small words can not guarantee that product adds the fastness in man-hour, excessive, after product completion of processing, be difficult to dismounting, not only efficiency is low, serious also can defective work piece surface, difficult quality guarantee.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of clamping device simple in structure, easily manufactured, that process for hard fragility flakelet series products is provided, and not only can guarantee the fastness of clamping, and clamping workpiece convenient disassembly, and efficiency is high.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of clamping device of hard fragility flakelet series products processing use, comprise vacuum generator and vacuum platform, and the vacuum way of vacuum platform and vacuum generator are connected; On vacuum platform, be distributed with work piece profile adapt groove, bottom portion of groove is fixedly bonded with and adapts with groove topography size and the rubber blanket of even thickness; On rubber blanket, be provided with equably some gas ports, gas port is through bottom portion of groove, and communicates with the vacuum way of vacuum platform.
The clamping device of above-mentioned a kind of hard fragility flakelet series products processing use, groove quantity can be for one or more; Described rubber blanket thickness is less than depth of groove.
Compared with prior art, the beneficial effects of the utility model are: the utility model by arranging rubber blanket on vacuum platform, laminating degree between work piece and clamp body is improved greatly, eliminated the clamping gap between the two, thereby can obtain powerful absorption dynamics, realize firm clamping, and the utility model be simple in structure, clamping efficiency is high, can greatly improve processing yield and the crudy of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail.
As shown in Figure 1, the clamping device of a kind of hard fragility flakelet series products processing use of the present utility model, is comprised of the vacuum platform 1 with vacuum way, vacuum generator 2 and rubber blanket 3.Vacuum platform 1 is connected by vacuum line and vacuum generator 2; Vacuum platform 1 is provided with the circular groove 4 adapting with work piece appearance and size; Round rubber pad 3 adheres to the bottom of groove 4 uniformly by strength adhesive, the inwall of its excircle and groove 4 is affixed, and upper end face is lower than the notch edges of groove 4; On rubber blanket 3, be evenly distributed with gas port 5, this gas port 5 runs through groove 4 bottoms, and communicates with the vacuum way of vacuum platform 1.
During clamping workpiece, groove 4 is put into in the edge of work piece alignment indentation 4, its bottom is contacted with rubber blanket 3, top is exposed to the outside of groove 4, then open vacuum generator 2, give vacuum platform 1 logical negative pressure, and by gas port 5, work piece is firmly held, complete the clamping to work piece.
Adopt clamping device of the present utility model can realize the perfection laminating of small-sized sheet workpiece and clamp body, the absorption affinity of utilizing to greatest extent negative pressure to produce, clamping is solid and reliable.Meanwhile, clamping tool of the present utility model is easy to processing, and low cost of manufacture is applicable to the clamping of various small-sized sheet products.
Claims (3)
1. a hard fragility flakelet series products is processed the clamping device of use, comprise vacuum generator and vacuum platform, the vacuum way of vacuum platform and vacuum generator are connected, it is characterized in that: on vacuum platform, be distributed with work piece profile adapt groove, bottom portion of groove is fixedly bonded with and adapts with groove topography size and the rubber blanket of even thickness; On rubber blanket, be provided with equably some gas ports, gas port is through bottom portion of groove, and communicates with the vacuum way of vacuum platform.
2. the clamping device of a kind of hard fragility flakelet series products processing use according to claim 1, is characterized in that: described groove quantity is one or more.
