Measuring device for wire drawing pulling force of automobile door lock

Abstract

The invention relates to a measuring device for wire drawing pulling force of an automobile door lock. The lower end of a protective cover is fixedly mounted on a base; an upper cross beam is fixed at the upper end of the protective cover; the upper end of a linear guide rod is fixed on the upper cross beam; the lower end of the linear guide rod is fixed on the base; the linear guide rod is equipped with a linear bearing; the upper end of a ball screw is mounted on the upper cross beam through an upper bearing component in a supporting manner; the lower part of the ball screw is mounted on the base through a lower bearing component in a supporting manner; the ball screw is equipped with a screw rod nut; a servo motor is connected with a speed reducer; the output shaft of the speed reducer is connected with the lower end of the ball screw through a shaft coupling; the linear bearing and the screw rod nut are together embedded inside a movable crossbeam; a sensor is fixed on the movable crossbeam; a lower clamp is mounted at the upper part of the sensor; a bending bearing is mounted at the lower part of the sensor; an upper clamp is fixed on the upper cross beam through the fixed shaft of the upper clamp. The measuring device for the wire drawing pulling force of the automobile door lock is simple in structure and convenient to use; the wire drawing pulling force of the automobile door lock can be accurately measured; the improvement of user experience is facilitated and the development of the automobile market is promoted.

Description

technical field [0001] The invention relates to a measuring device, in particular to a measuring device for the wire drawing force of an automobile door lock. Background technique [0002] With the rapid development of the automobile industry, people's comprehensive requirements for automobiles are also gradually increasing. In the past, only focusing on the performance indicators such as the displacement and fuel consumption of the car has risen to specific requirements for the exterior design and interior design of the car, and has been developed to the current requirements for the driving experience and ride comfort of the car. high. [0003] As we all know, car door locks are an indispensable part of civilian cars. The design of car door lock wire drawing is an important research project in the design of car door locks. Its actual use experience also affects people's consumption trends to a certain extent. , if the design is unreasonable, it is easy to cause discomfort...
