Description

Technical Field

[0001] The utility model relates to a cold-drawn guide rail positioning fixture. Background Art

[0002] In modern manufacturing, cold-drawn guide rails, due to their excellent mechanical properties and dimensional stability, are widely used in critical systems such as machine tools, automation equipment, and transportation vehicles. In particular, in elevator manufacturing, T-shaped cold-drawn guide rails, as core guide components, have a machining accuracy that is directly related to the safety and reliability of elevator operation. Traditionally, the fixing holes at the ends of elevator guide rails are typically drilled using a drilling machine. However, machine vibration during this process can easily cause the guide rails to deviate from their intended position, affecting the machining accuracy of the fixing holes and posing a potential threat to elevator safety.

[0003] To overcome this problem, current solutions rely on using fixtures to securely fix the elevator guide rails to the machine platform before drilling. However, existing fixture designs often only provide single-directional fixation, which can still cause the T-shaped cold-drawn guide rails to deviate to a certain extent, affecting the final processing quality.
