Accurately-matched sensor shell perforating device

Abstract

The invention discloses an accurately-matched sensor shell perforating device. The accurately-matched sensor shell perforating device comprises a base, wherein a bracket is mounted on the base; an upper cavity is mounted on the base; a cylinder is mounted on the bracket; a lower cavity is mounted on the cylinder; at least one through hole is formed in the upper cavity; a perforating column matched with the through hole of the upper cavity is arranged on the lower cavity; the lower cavity is positioned right under the upper cavity; a core material groove and a shell groove are arranged in each of the upper cavity and the lower cavity; the core material grooves of the upper cavity and the lower cavity construct a complete core material channel; the shell grooves of the upper cavity and the lower cavity construct a complete finished product channel; the diameter of the finished product channel is more than the diameter of the core material channel; an air channel is arranged in the lower cavity, and the finished product channel is communicated with a high pressure air pipe mounted on the lower cavity through the air channel. The accurately-matched sensor shell perforating device has the advantages that the accurate alignment matching of the upper cavity and the lower cavity is guaranteed, the phenomenon of malposition is avoided, the difficulty in packaging is reduced, and the packaging efficiency of the core material and the shell is improved.

Description

technical field [0001] The invention relates to an auxiliary tool used in the sensor manufacturing industry, in particular to a perforating device for an accurately fitted sensor coat. Background technique [0002] The automobile wheel speed sensor is mainly composed of induction head, wiring harness and accessories. The role of the induction head is to cooperate with the target gear installed on the chassis of the car to measure the speed of the car wheel, which is composed of coils, magnetic poles and other parts. On this basis, to ensure the normal operation of the sensor, the sensor must be properly installed on the chassis of the car, and there are many ways to install it. Now commonly used a kind of wheel speed sensor is to rely on the outer steel casing of the induction head to cooperate with a part, i.e. the elastic bush, and pack into the corresponding mounting hole of the chassis. When designing the sensor, it is necessary to combine the magnetic steel and the ma...
