The utility model discloses regard the fixed block as auxiliary fixtures, through setting up the step face three and the adaptation of bend bottom, realize with the quick clamping and the accurate positioning of bend, can make the bend of bottom area step face can realize on electric spark machine tool for processing, improved bend production efficiency, reduced bend manufacturing cost.
Description
Technical Field
The utility model relates to a semiconductor equipment part arc bend spark-erosion machining especially is used for fixing the anchor clamps that semiconductor equipment part bend was used on the spark-erosion machining machine tool.
Background
In the automatic punching and forming equipment for semiconductors, the final product obtained through the processes of plastic package forming, shearing and the like slides and is collected through a curve, the curve is shown in figure 1, a surface sliding groove is in an arc shape, the bottom surface is provided with three step surfaces, the dimensional precision is +/-0.01, the surface smoothness is high, and the final product is a key part and a difficult-to-process part in the punching and forming equipment. The thickness of the chute wall on the bend is less than 0.3mm, so that the chute is easy to deform and collapse by processing with methods such as numerical control milling and the like, the product percent of pass is low, and the production cost is high. In order to solve the problems, people adopt an electric spark machine tool to machine a sliding groove on a curve, but electric sparks are only suitable for plane machining, and the bottom surface of a circular arc curve part is a step surface, so that the electric spark machine tool can clamp and find a machining reference, which brings difficulty.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problem that the electric spark machining clamping of the arc-shaped thin-wall groove of the curve of the semiconductor part is difficult to find the machining reference.
In order to solve the above problem, the utility model adopts the following technical scheme: a fixing clamp for electric spark machining of an arc-shaped bend of a semiconductor device part is characterized by comprising a fixing block and a connecting device, wherein the bottom of the fixing block is a plane used for clamping on an electric spark machine tool, the upper surface of the fixing block is provided with three step surfaces matched with the bottom surface of the bend, the highest step surface is connected with a reference machining surface parallel to the bottom surface, more than two positioning holes are formed in the three step surfaces on the fixing block, and the fixing block is fixedly connected with the bend through the connecting device.
By adopting the technical scheme, the fixing block and the bend are fixedly connected by the connecting device after being positioned in the positioning hole by the pin, so that the centers of the fixing block and the bend are superposed together, the effects of quick positioning and accurate positioning are achieved, and then the electric discharge machining is carried out by using an electric discharge machine tool.
Preferably, the connecting device comprises a screw hole formed in the step surface of the fixing block and a screw matched with the screw hole, and the fixing block is fixedly connected with the curve by the connection of the screw and the screw hole. Welding, riveting or other attachment means may also be used.
In a further improvement, a receding groove is arranged between two adjacent step surfaces of the three step surfaces of the fixing block.
Preferably, the two screw holes and the two positioning holes are symmetrically distributed on two sides of the center line.
To sum up, the utility model discloses beneficial effect is: the utility model discloses regard the fixed block as auxiliary fixtures, through setting up the step face three and the adaptation of bend bottom, realize with the quick clamping and the accurate positioning of bend, can make the bend of bottom area step face can realize on electric spark machine tool for processing, improved bend production efficiency, reduced bend manufacturing cost.
