Problems solved by technology

When the brake hose is loaded into the car, due to the structural reasons of the car, some rubber hoses will have greater friction with the surrounding components during use, which will increase the wear on the outer wall of the hose and reduce the service life of the hose.
In order to minimize this unnecessary loss, it is necessary to add a protective spring to the outer wall of the rubber hose to protect the outer wall of the rubber hose; at present, in the production process, the protective springs are manually assembled, and because some springs are too long and too soft , when manual assembly is performed, the efficiency is very low, and it is easy to miss assembly, which will adversely affect the next process

Abstract

An automatic stretching device for springs is characterized by comprising a spring pushing device (1), a spring stretching device (2) and a spring fixing device (3). The spring pushing device (1) comprises an air cylinder I (4), an air cylinder support (5), a guide rod I (6), a pushing rod (7) and a lever connecting frame (8). The spring stretching device (2) comprises a linear guide rail (9), a base frame (10), an air cylinder II (11), a claming block I (12), an air cylinder III (13), a centering support (14), a guide rod II (15), a connecting frame (16), a synchronizing wheel (17), a synchronizing belt (18) and a servo motor (19). The spring fixing device (3) comprises a support base (20), a fixing rod support (21), a fixing rod (22), a clamping block II (23), a clamping jaw air cylinder (24), an air cylinder connecting frame (25), an air cylinder fixing frame (26) and an air cylinder IV (27). The automatic stretching device can automatically stretch a protection spring on the outer wall of a rubber tube, automatic production can be carried out, and production efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical devices and relates to a stretching mechanism, in particular to an automatic stretching spring device for automatically stretching and compressing a spring to a certain length and a control method thereof. Background technique [0002] With the rapid development of the domestic economy, especially the rapid development of the automobile industry, hoses have become an indispensable material in daily life and industrial development. When the brake hose is loaded into the car, due to the structural reasons of the car, some rubber hoses will have greater friction with the surrounding components during use, which will increase the wear on the outer wall of the hose and reduce the service life of the hose. . In order to minimize this unnecessary loss, it is necessary to add a protective spring to the outer wall of the rubber hose to protect the outer wall of the rubber hose; at present, in the produ...
