Description

Technical Field

[0001] The utility model relates to the technical field of pressure sensors, in particular to a clamping mechanism of pressure sensor production equipment. Background Art

[0002] Pressure sensor is the most commonly used sensor in industrial practice. The output of ordinary pressure sensor is analog signal. Analog signal means that the information parameter is expressed as a continuous signal within a given range, or within a continuous time interval, the characteristic quantity representing the information can be presented as a signal of any numerical value at any moment. The pressure sensors we usually use are mainly made using piezoelectric effect.

[0003] A Chinese patent with authorization announcement number CN219444828U discloses a clamping mechanism for pressure sensor production equipment, which belongs to the technical field of pressure sensor production. The clamping mechanism of the pressure sensor production equipment includes a basic component and a rotating component. The basic component includes a clamping part and a lifting part. The lifting part is arranged above the clamping part. When the height of the clamp needs to be lowered, the rotating wheel is rotated so that the worm gear drives the middle connecting rod to rotate, and then the connecting rods on both sides can be rotated through transmission. At this time, the three connecting rods rotate synchronously, driving the screw to rotate downward along the inner wall of the screw sleeve. At this time, the three connecting rods drive the position of the fixed frame to move downward. The clamping mechanism of the pressure sensor production equipment can achieve the effect of rotating the three connecting rods together, thereby ensuring that the three connecting rods rotate in unison, and also saving manpower, giving users a better use experience.

[0004] However, when the above scheme clamps the pressure sensor, the electric push rod is used to push the clamp head to move relatively to clamp the pressure sensor, and the clamping device cannot freely adjust the direction, resulting in the clamping device being unable to reach an ideal position or angle, affecting work efficiency and accuracy. Moreover, when the pressure sensor needs to be tested using a hydraulic cylinder, the operation is restricted due to the limitation of the connecting rod, and the system cannot be used in multiple scenarios, resulting in low applicability. Therefore, a clamping mechanism for pressure sensor production equipment is proposed to solve the above-mentioned problems. Utility Model Content
