Press-fitting fixture for spring of pedal

Abstract

The invention proposes a pedal spring pressing fixture, which includes a fixture body, the fixture body includes a base, and the base is respectively provided with a limiting mechanism for limiting the pedal bracket assembly assembly and a positioning mechanism for adjusting the assist spring assembly Compression pressing mechanism; the limiting mechanism includes a first positioning pin and a second positioning pin as well as a first pressing plate and a second pressing plate, and the pressing mechanism is correspondingly arranged in front of the limiting mechanism, and the pressing mechanism includes a vertical The cylinder set straight upwards is fixedly connected with a pressure head on the piston rod of the cylinder, and one end of the pressure head is provided with a slot corresponding to the guide rod in the booster spring assembly assembly. When in use, the pressure head is clamped on the upper part of the guide rod. A limiting plate is arranged on the end cover of the cylinder. The fixture has a simple structure, is easy to manufacture, has a short debugging period and low cost, is beneficial to improving enterprise benefits, and can be popularized and used.

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
