Abstract

The invention relates to the technical field of detection, in particular to a quality detecting device for a pressure sensor. The quality detecting device for pressure sensor comprises a base, a standard piece and a to-be-detected piece. The center of the top end of the base is arranged with a detecting box, the inner center of the detecting box is arranged with a partition plate, and the partition plate divides the detecting box into a left detecting chamber and a right detecting chamber. The top ends of the two detecting chambers are arranged with a placement port respectively, and the bottom ends of the two detecting chambers are arranged with a sliding groove respectively. A sliding rod is slidably connected inside each sliding groove, the top end of the sliding rod is arranged with apushing plate, and the bottom end of the sliding rod extends to the outside through the sliding groove, the side wall of the pushing plate is arranged with a touching block, the bottom end of the detecting box is arranged with a driving chamber, the left end and the right end of the driving chamber are respectively arranged with a cylindrical cavity, and a telescopic rod is fixedly mounted insideeach cylindrical cavity. The quality detecting device for pressure sensor is simple in structure, convenient to operate, capable of detecting multiple types of pressure sensors, and has a pressure buffer structure, greatly protects the integrity of the products, prevents the products from being damaged, and has great practicability.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a quality detection device for a pressure sensor. Background technique [0002] With the rapid development of industrial automation and intelligence, pressure sensors are more and more widely used. Automobiles, air conditioners, automation equipment, intelligent robots, etc. are used in large quantities. In order to ensure the quality consistency and necessary accuracy of pressure sensors, it is often necessary to Each pressure sensor undergoes factory or incoming inspection. However, at present, the manual gas (hydraulic) pressure method is generally used for calibration, and the detection data and calculation accuracy are manually recorded. Due to manual detection, the pressure control ability of the detection equipment is poor, it is easy to cause pressure overadjustment and difficult to stabilize the pressure, the detection efficiency is extremely low, and it is easy to ge...
