Sensor accessory shell manufacturing and processing machine and processing technology

Abstract

The invention belongs to the technical field of sensors, and particularly relates to a sensor accessory shell manufacturing and processing machine and processing technology. The processing technology comprises the following steps of 1, carrying out casting molding, specifically, carrying out casting molding on a sensor accessory shell, and removing molding sand on the surface of the sensor accessory shell; 2, removing molding sand in a hole, specifically, removing the molding sand in a vent hole of the sensor accessory shell; and 3, carrying out surface treatment, specifically, polishing the surface of the sensor accessory shell obtained after the molding sand is removed, and then spraying protective paint, wherein the step 2 is completed with the assistance of the sensor accessory shell manufacturing and processing machine. According to the machine and technology, when the molding sand in the vent hole of the sensor shell is removed, the sensor shell is fixed to an annular base all the time and cannot collide with other objects, and thus damage is avoided; and the molding sand does not collide with the sensor shell at a high speed and does not escape from a square frame, so that the damage from the molding sand to human skin is avoided.

Description

technical field [0001] The invention belongs to the technical field of sensors, and in particular relates to a manufacturing and processing machine and a processing technology for a sensor accessory shell. Background technique [0002] A sensor is a detection device that can sense the measured information and convert the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, and display. , recording and control requirements. Oxygen sensor is an essential component in automobiles. In order to obtain a high exhaust gas purification rate and reduce the components of carbon monoxide, hydrocarbons and nitrogen oxides in the exhaust gas, an EFI vehicle must use a three-way catalytic converter to precisely control the air-fuel ratio, so that the air The fuel ratio is always close to the theoretical value. The oxygen sensor has a characteristic th...

Problems solved by technology

[0005] The present invention provides a processing machine and processing technology for sensor fitting shells, aiming to solve the following problems in the current manufacturing and processing process of sensor fitting shells: after the casting of sensor shells is completed, it is necessary to remove the molding sand on the surface and in the ventilation holes. In the process of cleaning the molding sand in the vent hole of the sensor casing, it is mainly carried out by hand-held air guns. The sensor casing is easy to be separated from the human hand under the action of high-speed airflow, causing damage to the sensor casing; the molding sand impacted by the air gun is easy to hit the surface of the sensor casing and cause sensor The surface of the shell is damaged, and the molding sand is easy to touch the human skin under the action of the air flow, causing harm to the operator
