AI Technical Summary
In the existing technology, when manually tightening the pressure switch, it is impossible to accurately control the tightening force. If the tightening force is too small, it may loosen. If it is too large, it may cause the connecting components to break or deform, affecting the finished quality of the oil pipeline.
A pressure switch locking device for automotive pipelines is adopted, which uses a combination of a servo tightening machine, a linear output device and a spring connecting pin to achieve automatic locking of the pressure switch. The tightening force is controlled by the torque sensor of the servo tightening machine, and the spring connecting pin is used to counteract inertial rebound, ensuring that the tightening degree of each pressure switch is consistent.
The automatic tightening of pressure switches has been achieved, ensuring that the tightening degree of each pressure switch is consistent, avoiding damage to parts caused by inertial springback, and improving the stability of the device and the quality of the finished product.

Description
Technical Field
[0001] This utility model relates to the technical field of automotive parts installation, and more specifically, to a pressure switch locking device on an automotive pipeline. Background Technology
[0002] An oil pipeline pressure switch is a device that controls a circuit switch based on pressure changes. A pressure sensor is installed on the oil pipeline to monitor internal pressure variations. When the pressure exceeds a preset upper or lower limit, the pressure sensor sends a signal to the circuit controller. The circuit controller then uses an output device to control the oil transportation system, enabling it to detect pipeline pressure, prevent pipeline rupture, and extend equipment lifespan.
[0003] Currently, the installation of pressure switches onto finished oil pipelines is generally done manually, using servo tightening machines to tighten the bolts. However, manual tightening cannot be precisely controlled. If the tightening torque and force cannot be precisely controlled, the clamping force may be too small, and the bolts may loosen due to vibration or cyclic load. If the clamping force is too large, it can easily cause the connecting components to break or deform. This installation method ultimately results in inconsistent tightening of the pressure switches on the oil pipeline, and in severe cases, it may even cause damage. Based on the above problems, we propose a tightening device for pressure switches on automotive oil pipelines. Utility Model Content
