Press-fitting fixture for spring of pedal

Abstract

The invention provides a press-fitting fixture for a spring of a pedal. The fixture comprises a fixture body; the fixture body comprises a base; a limiting mechanism for limiting a pedal support component assembly and a pressing mechanism for pressing a boosting spring component assembly are arranged on the base; the limiting mechanism comprises a first positioning pin, a second positioning pin, a first pressing plate and a second pressing plate; the pressing mechanism is correspondingly arranged in front of the limiting mechanism and comprises an air cylinder arranged vertically upwards; a pressing head is fixedly connected onto a piston rod of the air cylinder; a clamping groove corresponding to a guide rod in the boosting spring component assembly is arranged at one end of the pressing head; the pressing head is clamped at the upper part of the guide rod during use; and a limiting plate is arranged on an end cover of the air cylinder. The fixture is simple in structure, easy to manufacture, short in adjustment period, low in cost, beneficial to increase of the enterprise benefit and capable of being popularized for use.

Description

technical field [0001] The invention relates to the technical field of assembly of automobile parts, in particular to a fixture used in the press-fitting process of an automobile clutch pedal booster spring. Background technique [0002] With the development of the global automobile industry and the improvement of living standards, the automation level of auto parts production is also getting higher and higher. Therefore, in the installation process of the automobile clutch pedal booster spring, it is required to have stable operation, reliability, and high assembly efficiency. , high pass rate, low labor intensity and other advantages. [0003] Such as figure 1 , figure 2 As shown, the existing booster spring clutch pedal assembly is usually composed of a rotating shaft 9 and a self-locking nut 10 to connect the pedal bracket assembly 1 and the booster spring assembly 2 (composed of a mounting seat 5, a guide rod 6 and a booster spring 7) , Pedal swing arm assembly asse...

AI Technical Summary

Problems solved by technology

At present, most clutch pedal booster springs are installed manually or with simple auxiliary tools. During the assembly process, the huge spring force of the clutch pedal booster spring must be overcome. Therefore, it is laborious to assemble, with low installation efficiency, high labor intensity, and safe operation. low performance, unable to meet the needs of mass production of such clutch pedals, and also has the disadvantage of poor assembly accuracy, which affects the development of enterprises
