Abstract
The utility model discloses a vacuum clamping device grinded by a bimetallic valve plate, and is characterized by comprising a vacuum pump, wherein the vacuum pump is connected with one end of a distribution joint through a vacuum hose, a pressure meter is arranged on the other end of the distribution joint, the distribution joint is connected with a vacuum platform, and the vacuum platform is provided with a work piece. The vacuum clamping device, provided by the utility model, has the characteristics of quick clamping speed, good processing stability, high production efficiency and low production cost.
Description
Technical field
The utility model relates to the vacuum clamping device of a kind of bimetallic valve plate grinding, belongs to the manufacturing technology field of bimetallic material.
Background technology
The bimetallic valve plate is in the process of cross grinding, because an end face of bimetallic valve plate is nonmagnetic substance, in grinding process, can not use traditional electromagnetism chuck method to be located clamping, the location clamps becomes a problem of having a bad headache, the location that needs very complicated anchor clamps of design to solve workpiece clamps problem, becomes a difficult problem in the grinding process.Valve plate belongs to thin wall component simultaneously, and when its maximum difficult point clamped exactly, workpiece very easily produced distortion.
Summary of the invention
The purpose of this utility model is that workpiece produces the problem of distortion when solve clamping, and provides a kind of clamping speed fast, the vacuum clamping device of good processing stability, production efficiency is high, production cost is low bimetallic valve plate grinding.
In order to achieve the above object, the utility model provides the vacuum clamping device of a kind of bimetallic valve plate grinding, it is characterized in that, comprise vavuum pump, vavuum pump is connected with an end of distribution joint by vacuum hose, the other end of distribution joint is provided with pressure gauge, and distribution joint is connected with vacuum platform, and vacuum platform is provided with workpiece;
Preferably, described vacuum platform is provided with alignment pin.
Preferably, described alignment pin is arranged on the lower position of pin-and-hole on the workpiece.
Preferably, described workpiece below evenly is provided with adsorption hole, and workpiece is fixed by 2 alignment pins.
Preferably, described adsorption hole is 10-100.
The utility model makes between workpiece and the vacuum platform and produces negative pressure by taking out the air between workpiece and the vacuum platform, because atmospheric effect, workpiece is adsorbed on the workbench firmly.Change the size of absorption affinity by regulating the pressure size, the deflection of workpiece is controlled at minimum.The utility model can be simplified the operating process of clamping workpiece greatly, has improved significantly workpiece location and fastening speed, has improved production efficiency, reduced production cost, clamping workpiece is convenient, and the clamping deformation amount is little, has greatly improved machining accuracy and the working (machining) efficiency of workpiece.
Description of drawings
Fig. 1 is the structural representation of the vacuum clamping device of a kind of bimetallic valve plate of the utility model grinding;
Fig. 2 is the structural representation of multipoint mode absorption on the vacuum platform.
Among the figure: 1 is vavuum pump, and 2 is vacuum hose, and 3 is distribution joint, and 4 is pressure gauge, and 5 is vacuum platform, and 6 is workpiece, and 7 is alignment pin, and 8 is adsorption hole.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.
Embodiment 1
As shown in Figure 1 and Figure 2, the utility model is the vacuum clamping device of a kind of bimetallic valve plate grinding, partly formed by vavuum pump 1, vacuum platform 5 and associate member etc., vavuum pump 1 provides negative pressure, vacuum hose 2 connects vavuum pump 1 and distribution joint 3, the vacuum area that distribution joint 3 is selected on the vacuum platform 5, pressure gauge 4 shows the size of force value, place workpiece to be machined 6 on the vacuum platform 5, and by 2 alignment pins, 7 location, prevent that workpiece 6 is mobile in grinding process, evenly be provided with adsorption hole 8 around the alignment pin 7.Vacuum platform 5 adopts the plane contact of multipoint mode absorption, according to the shape of workpiece, 30 adsorption holes 8 is set uniformly below workpiece 6, reduces the deflection of clamped workpiece 6, and the location that is applicable to thin-wall part clamps.Workpiece to be machined 6 is placed on assigned address on the vacuum platform 5, vavuum pump 1 is started working, by vacuum hose 2 and distribution joint 3, take out the air of 5 of workpiece 6 and vacuum platforms by adsorption hole 8, make 5 of workpiece 6 and vacuum platforms form negative pressure, because the effect of external atmosphere pressure, workpiece 6 is adsorbed on the vacuum platform 5 firmly.Change the size of absorption affinity by regulating the pressure size, the deflection of workpiece 6 is controlled at minimum, its force value size can show by pressure gauge 4.After grinding was finished, stably inflation was advanced in the vacuum platform 5, made 5 of workpiece 6 and vacuum platforms become zero air pressure or very little positive air pressure by negative pressure, and workpiece 6 just can be taken off easily.
By regulating the suction of vavuum pump 1, thereby improved greatly the problem on deformation of workpiece 6.Adopt this anchor clamps grinding valve plate, guaranteed that namely machining accuracy has improved again working (machining) efficiency, surface that simultaneously can injuring part.
It is fastening that the utility model adopts the negative pressure technology that workpiece is carried out, and can be applied to the clamping of nonmagnetic substance workpiece.
Embodiment 2
The utility model is the vacuum clamping device of a kind of bimetallic valve plate grinding, place workpiece to be machined on the vacuum platform, and by being placed on 2 alignment pin location of workpiece pin-and-hole position, evenly being provided with 100 adsorption holes around the alignment pin, other structures are with embodiment 1.
Embodiment 3
The utility model is the vacuum clamping device of a kind of bimetallic valve plate grinding, place workpiece to be machined on the vacuum platform, and by being placed on 2 alignment pin location of workpiece pin-and-hole position, evenly being provided with 10 adsorption holes around the alignment pin, other structures are with embodiment 1.
