This invention discloses a high-precision miniature Z-axis positioning platform for use in the field of precision platforms. By integrating an encoder, displacement sensor, and reader to construct a multi-level displacement monitoring system, it can compare the matching relationship between the voice coil motor command, the middle plate displacement, and the stage displacement under normal load conditions. When jamming occurs, it can assist in locating the fault source based on the displacement error and displacement curve status among the three. Furthermore, a clamping and tilting roller mechanism controlled by a miniature electric actuator and a drive motor is introduced. At the moment jamming is detected, the sample is actively clamped and lifted, causing it to disengage from the abnormally vibrating stage. This reduces the shaking and displacement of the sample caused by stage jamming, ensuring the stability of the sample during precision operations.

This invention discloses a laser welding device for the housing of an electromagnetic expansion valve with a valve core. The flat electromagnetic expansion valve housing with a valve core is inverted and fixed on a welding fixture and rotates. It also includes a valve core protection mechanism, which includes a heat-insulating positioning sleeve disposed inside the housing and located between the laser weld area and the valve core, a heat dissipation ring disposed on the fixture, and a covering heat dissipation base. There is an air heat-insulating gap between the heat-insulating positioning sleeve and the laser weld area. The heat-insulating positioning sleeve, together with the air heat-insulating gap, blocks the heat conduction from the laser weld area to the valve core. The heat dissipation ring and the covering heat dissipation base respectively guide the blocked heat to the outside of the electromagnetic expansion valve housing for dissipation, thereby forming a directional heat conduction path on the electromagnetic expansion valve housing from the laser weld area to the external heat dissipation ring and the covering heat dissipation base. This invention can effectively prevent the internal valve core from being deformed or damaged due to severe heat conduction during the circumferential welding process of the electromagnetic expansion valve housing, thereby improving the yield.
