Based on your previous focus on LVDT sensor installation and coaxiality control in hot runner scenarios, the following steps can ensure installation coaxiality:
Reference Positioning: Using the motion axis of the hot runner needle valve as a reference, attach a dial indicator to the needle valve and calibrate the coaxiality of the LVDT mounting base, controlling radial runout within 0.02mm.
Tooling Assistance: Use a dedicated coaxial positioning fixture to fix the sensor, ensuring the probe and the center hole of the needle valve are perfectly aligned, avoiding visual deviations caused by manual installation.
Flexible Transition: Use a universal flexible connector to connect the probe and the needle valve, offsetting minor coaxial deviations during installation and preventing lateral force jamming.
Dynamic Verification: Manually drive the needle valve to its full stroke, confirming no jamming or additional resistance throughout the entire process. Once coaxiality is achieved, lock the mounting base.
This process can control coaxiality errors within the allowable range, adapting to the high-precision detection requirements of hot runner systems.
