Variable diameter swinging mechanism of spring machine

Abstract

The invention discloses a variable diameter swinging mechanism of a spring machine, and belongs to the technical field of key parts on a spring machine. The variable diameter swinging mechanism of the spring machine comprises a cam, a swinging rod, an adjusting block and a slide block, and also comprises a variable diameter lever which is of a structure in the shape of an inverted Chinese character 'ren'; the maximum swinging angles of the variable diameter lever and the swinging rod are all less than or equal to 10 degrees; the lower part of the variable diameter lever is installed on a lever pole; the geometric position angle of the lever pole and the cam with a rolling bearing is 90 degrees; the connecting line of the center of the cam and the swinging center of the variable diameter lever is overlapped with a central line; the middle part of the variable diameter lever is in contact connection with a second screw bolt; a first screw bolt is installed at the tail end of the variable diameter lever; the first screw bolt and the second screw bolt are both provided with spherical structures; and the central lines of the first screw bolt and the second screw bolt pass through the centers of an upper top spring base and a lower top spring base respectively. The variable diameter swinging mechanism of the spring machine provided by the invention can be used in the spring machine and has the advantages of simple structure, high transmission precision, good stability and the like.

Description

technical field [0001] The invention relates to a variable-diameter swing mechanism of a spring machine, which belongs to the technical field of key parts on a spring machine. Background technique [0002] The variable-diameter swing mechanism is an essential structure of the spring machine, but the current variable-diameter swing structure of the spring machine mainly includes the cam 1a, the first swing rod 2a, the second swing rod 3a, the third swing rod 4a and the upper slider 5a , the lower slider 6a, the lower end of the upper slider 5a is equipped with an upper top spring seat 7a, the lower end of the lower slider 6a is equipped with a lower top spring seat 8a, and the upper top spring seat 7a and the lower top spring seat 8a are respectively equipped with upper fixed spring pins 7b, the lower top spring pin 8b, the spring reaches the bottom of the upper top spring pin 7b and the lower top spring pin 8b through the guide plate 9a, the rolling bearing 10a is between th...

Problems solved by technology

However, with such a structure, the swing angle between the swing rods is relatively large, so that the transmission pressure angle is large and the sliding rate is large. During use, the transmission accuracy and stability are low, the spring machine wears large, and a set of devices only Can make left-handed spring or right-handed spring
