Problems solved by technology

During the manual assembly of the main spring, a force of 300-350N is required to compress the main spring to the specified length, and the installation personnel have a high work intensity; the manual assembly method using spring pliers is very inefficient and difficult to mass-produce; once the main spring falls off during the assembly process , may cause serious personal injury; when the spring clamp is released during the assembly process, it is difficult to accurately control the position of the main spring on the fixed shaft of the bracket. If the installation position of the main spring deviates, it may cause abnormal noise in the driving mechanism during operation There will be hidden dangers of deformation of the spring bracket, and in severe cases, the entire driving mechanism will not work normally, resulting in product quality problems

Abstract

The invention discloses an assembly method for a main spring pressing-in device and relates to the field of mechanical assembly. An upper fixing shaft (5) and a lower fixing shaft (10) are fixedly connected to a spring support (16), and a handle (1) is connected to a stroke track support (12) through a handle fixing shaft (11); a pressing plate (2) is connected to the stroke track support (12) through a pressing plate fixing shaft (14); a stroke rolling shaft (3) is fixedly connected to the handle (1); the stroke rolling shaft (3) makes contact with the pressing plate (2) and can drive the pressing plate (2) to move; a main spring (4) is fixed into the spring support (16); and under driving of the stroke rolling shaft (3), the pressing plate (2) presses the main spring (4) into the position between the upper fixing shaft (5) and the lower fixing shaft (10). The assembly method for the main spring pressing-in device is safe, efficient and capable of saving labor.

Description

technical field [0001] The invention relates to the field of mechanical assembly, in particular to an assembly method of a main spring press-in device. Background technique [0002] The existing driving mechanism uses the main spring to press the main spring into the bracket. The spring fixing shaft is mainly manually assembled. The main spring is clamped and compressed by the spring pliers, and then put into the bracket. After the main spring fixing shaft is released, the spring pliers are released to clamp the main spring to the bracket both ends of the shaft. During the manual assembly of the main spring, a force of 300-350N is required to compress the main spring to the specified length, and the installation personnel have a high work intensity; the manual assembly method using spring pliers is very inefficient and difficult to mass-produce; once the main spring falls off during the assembly process , may cause serious personal injury; when the spring clamp is released ...
