Problems solved by technology

[0003] Traditional straightening machines usually use the top to clamp the workpiece. Due to the uneven curvature of the workpiece, there will be a large jump during processing. At the same time, the top is responsible for driving the workpiece to rotate, which is not flexible enough.

Abstract

The invention discloses a pressure point and fulcrum combined mechanism applied to a straightening machine. The pressure point and fulcrum combined mechanism comprises a left bracket, an auxiliary driving motor, a pair of rotary top shafts, a plurality of anvils and a friction wheel driving mechanism, the friction wheel driving mechanism comprises a friction wheel driving mechanism body, a circular-truncated-cone-shaped friction wheel arranged at one end of the friction wheel driving mechanism body and a pressing wheel driving motor used for driving the circular-truncated-cone-shaped friction wheel to rotate. A radial driving motor is arranged on the outer side of the friction wheel driving mechanism body in the horizontal direction and used for driving the friction wheel driving mechanism body to rotate, so that the circular-truncated-cone-shaped friction wheel gets close to the shaft workpiece and drives the shaft workpiece to rotate in the circumferential direction. According to the workpiece driving mechanism, the circular-truncated-cone-shaped friction wheel drives the workpiece to rotate through static friction, meanwhile, the whole driving mechanism can rotate in the plane between the axis of the workpiece and the ground, and therefore the driving effect on the workpiece is ensured. The device has the advantages of being flexible, high in adaptability and capable of meeting the requirements of workpieces with different bending degrees.

Description

technical field [0001] The invention relates to the straightening technology of a shaft blank workpiece, in particular to a combination device of a pressure point and a fulcrum without a top, which utilizes a friction wheel to frictionally drive the workpiece. Background technique [0002] Shaft parts will be bent and deformed during machining or heat treatment, and the bent and deformed parts will have a lot of influence on the next finishing process. In order to obtain the minimum cutting amount allowed by the next process, reduce waste parts and increase yield, save processing and raw material costs, and ensure that the workpiece meets strict final design tolerance requirements, automatic straightening machines have become indispensable after heat treatment for such products. key equipment. [0003] The traditional straightening machine usually uses the top to clamp the workpiece. Due to the uneven curvature of the workpiece, there will be a large jump during processing....
