Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a detection equipment based on a pressure sensor. Background Art

[0002] A pressure sensor is a device or apparatus that can sense pressure signals and convert them into usable output electrical signals according to certain rules. A pressure sensor is usually composed of a pressure sensitive element and a signal processing unit. According to different test pressure types, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors and absolute pressure sensors. Pressure sensors need to be tested after they are manufactured. At this time, a detection device based on a pressure sensor is needed.

[0003] When the detection equipment in the prior art detects and processes the sensor, it can only detect and process one sensor at a time. When it is necessary to detect and process other sensors, it is necessary to first fix the other sensors to the corresponding positions on the detection equipment, and then detect and process the other single sensors. After the detection is completed, they are unloaded and processed, and the cycle is repeated. Although this method can also effectively detect and process the sensors, when detecting and processing the sensors, a single sensor needs to be repeatedly loaded and unloaded. When the number of sensors that need to be detected is large, it takes a lot of time and effort, thereby greatly reducing the detection efficiency of the sensor.

[0004] Compared with the Chinese patent with publication number CN218765783U, the utility model belongs to the field of detection equipment, especially a detection equipment for pressure sensor production. In view of the problem that the mounting groove on the existing fixing component mounting seat cannot be adjusted, resulting in the inability to fix pressure sensors of different models and sizes, and the practicality is low, the following scheme is proposed, which includes a working plate, the bottom four corners of the working plate are fixedly connected with support feet for supporting the working plate, the top of the working plate is fixedly connected with a support frame, one side of the support frame is fixedly connected with a display control box, and the top of the support frame is fixedly connected with a cylinder. The two sides of the sensor body of different models and sizes can be adjusted and fixed by the first adjustment mechanism, and the other two sides of the sensor body can be adjusted and fixed by the second adjustment mechanism. The sensor body can be positioned by the first adjustment mechanism and the second adjustment mechanism so that the sensor body is located at the center of the working plate, which is convenient for the detection component to detect.

[0005] The above scheme can very conveniently perform fixed processing on sensors of different specifications, but when detecting and processing the sensors, it can still only detect and process a single sensor. When a large number of sensors need to be detected, the above scheme still needs to repeatedly load and unload the single sensor, which fails to solve the problems raised in the above background technology.

[0032] The above working principle: when it is necessary to detect and process the sensor body 15, it is only necessary to first fix multiple sensor bodies 15 of different specifications on the support plate 3 through the fixing assembly. After the sensor body 15 is fixed, the staff only needs to operate the device 7 to start the operation of the adjustment assembly. At this time, the adjustment assembly can effectively drive the lifting plate 5 to descend synchronously, and the lifting plate 5 then drives the connecting rod 19 and the mounting sleeve 20 to move synchronously, and the mounting sleeve 20 then drives the connecting plate 21 and the pressure hammer 22 to move synchronously. When the bottom of the pressure hammer 22 contacts the upper surface of the sensor body 15, the sensor body 15 can be detected and processed.

When the pressure hammer 22 needs to be disassembled and replaced, it only needs to press the plug-in rod 25 first, and the plug-in rod 25 will The second telescopic rod 24 and the reset spring 26 are squeezed synchronously. When the plug-in rod 25 is disengaged from the guide groove inside the mounting sleeve 20, the connecting disk 21 can be pulled out from the inside of the mounting sleeve 20. At this time, the pressure hammer 22 can be disassembled. When it is necessary to install the pressure hammer 22 of different specifications and shapes, it is only necessary to first plug the connecting disk 21 into the inside of the mounting sleeve 20, and then release the plug-in rod 25. At this time, the reset spring 26 is reset, driving the plug-in rod 25 to move synchronously. When the plug-in rod 25 is plugged into the guide groove inside the mounting sleeve 20, the mounting sleeve 20 and the connecting disk 21 can be fixed.
