Clamping die used for sensor base drilling

Abstract

The invention discloses a clamping die used for sensor base drilling. The clamping die comprises a die body of a single-layer structure. A set of workpiece holes are formed in the die body. A positioning block in interference fit with the corresponding workpiece hole is arranged in each workpiece hole. A positioning hole is formed in the center of each positioning block. The positioning holes areconcentric with the workpiece holes. The positioning blocks are used for achieving height positioning on sensor bases placed in the workpiece holes. The two rows workpiece holes are arranged in parallel. Two fixing pins are arranged in the die body in a penetrating manner and are used for fixing the positioning blocks in the two rows of workpieces correspondingly in a penetrating and inserting manner. The single-layer die body is adopted, the thickness of the die body is the same as that of an original double-layer die plate, and the die body is not likely to deform in the machining process when being heated; and the height positioning problem and the concentric problem are solved at the same time through the annular positioning blocks, on one hand, the positioning blocks are in interference fit with the workpiece holes, on the other hand, the positioning blocks are firmly fixed through the fixing pins, the phenomenon that the positioning holes of the positioning blocks and the workpiece holes are dislocated cannot occur, it is ensured that the workpiece holes and the positioning holes can be accurately concentric in the use process, and the product quality is ensured.

Description

technical field [0001] The invention relates to the technical field of sensor base manufacturing, in particular to a clamping mold for drilling a sensor base. Background technique [0002] During the manufacturing process of the sensor base, holes need to be drilled on the base, usually by a drilling machine. When drilling, the sensor base needs to be placed in the clamping mold for positioning. The existing clamping mold is composed of two templates. The workpiece hole of the upper template and the positioning hole of the lower template cannot be precisely concentric, and the two templates are easily deformed due to their thin thickness, so that the workpiece cannot be concentric during processing. It often occurs that the workpiece hole and the positioning hole are misaligned, and qualified products cannot be produced normally. Contents of the invention [0003] The object of the present invention is to provide a clamping mold for drilling a sensor base. The mold can e...
