Torsion spring two-end machining device and method and torsion driving device

Abstract

The invention relates to the field of torsion spring machining, in particular to a torsion spring two-end machining device and method and a torsion driving device. The device comprises a first machining mechanism and a second machining mechanism. The first machining mechanism and the second machining mechanism each comprise a machining base, a machining rod and a steel sleeve. The machining rod is provided with machining gear teeth and a machining groove. A first machining head comprising a first protrusion and a first machining part is fixedly arranged at a machining end of the machining rod of the first machining mechanism, and a second machining head comprising a second groove and a second machining part is fixedly arranged at a machining end of the machining rod of the second machining mechanism. The outer surface of the first protrusion is matched with the second groove, and the first machining part and the second machining part make contact with different bent sections on the two sides of the bent spring steel in a feeding clamping device correspondingly. According to the device, the first machining mechanism and the second machining mechanism are arranged on the two sides of two pieces of oppositely-folded spring steel correspondingly to machine the two pieces of spring steel at the same time, and the torsional spring machining efficiency is improved.

Description

Technical field [0001] The present invention relates to the field of torsion spring, and more particularly to a torsion spring end processing apparatus, method, and drive torsion devices. Background technique [0002] The torsion spring belongs to a coil spring. The end of the torsion spring is secured to other components, and when other components are rotated about the center of the spring, the spring pulls them back into the initial position, producing torque or rotational force. The torsion spring can store and release the angular energy or the axle rotating arm in the spring body is static to fix a device. Such springs are typically neutral, but there is a pitch between the spring rings to reduce friction. They generate resistance to rotation or rotational external force. According to the application requirements, the rotation of the torsion spring (clockwise or counterclockwise) is designed to determine the springs. Each loop or closely round or separately, can be detrimenta...

Problems solved by technology

The prior art has the following disadvantages: first fix the processing rod at one end of the spring steel to process the other end, then turn the spring steel over and clamp the processed end of the spring steel, and process the remaining unprocessed end; that is, it needs to be divided into two Complete the processing of both ends of the torsion spring, which reduces the processing efficiency of the torsion spring
