Camshaft sensor seat fixture and camshaft sensor processing method

Abstract

The invention discloses a camshaft sensor seat fixture. The camshaft sensor seat fixture comprises a flange plate, a screw, an upper supporting plate, a pressing block, a backing plate and a lower supporting plate. The upper supporting plate and the lower supporting plate are fixed on the upper portion and the lower portion of the flange plate respectively, the screw is connected with the upper supporting plate through a threaded hole penetrating the upper supporting plate, the lower end of the screw is fixedly connected with the pressing block, the backing plate is arranged on the lower supporting plate, and locating pins are arranged on the backing plate. In order to enhance stability of the fixture, the camshaft sensor seat fixture further comprises first reinforcing ribs which are arranged between the upper supporting plate and the lower supporting plate. The camshaft sensor seat fixture has the advantages that a camshaft sensor seat processing technology is improved, processing content which can be completed by previous five processes can be completed only by two processes currently, and accordingly, production efficiency can be improved, processing personnel can be reduced, cost can be lowered and product quality can be improved.

Description

technical field [0001] The invention relates to the field of camshaft sensor processing, in particular to a camshaft sensor seat fixture and a camshaft sensor processing method. Background technique [0002] The camshaft is a part of the engine's gas distribution mechanism. It is responsible for driving the valve to open and close on time. Its function is to ensure that the engine regularly sucks fresh combustible gas into the cylinder during operation, and discharges the burned exhaust gas out of the cylinder in time. The camshaft is a very important part of the engine, it will affect the performance of the whole engine, and the signal wheel installed at the end of the camshaft will work together with the nearby phase sensor, the sensor collects the position signal of the valve camshaft, through the sense of the cam The phase of the shaft signal wheel and pass it to the ECU. The ECU determines the top dead center position of the engine cylinder compression through the sens...

Problems solved by technology

[0004] figure 1 It is a schematic diagram of the processed camshaft position sensor seat. It can be seen that its shape is irregular, and an inner hole is provided in one of the end faces. In the past, the processing procedures were many and complicated, mainly including the following five procedures: milling Plane, reaming, chamfering, reaming, each process requires different processing equipment and tools, resulting in a large demand for personnel and equipment requirements, resulting in long processing time, low production efficiency, high cost and product quality instability and many other issues
