Vertical spinning machine

Abstract

The invention discloses a vertical spinning machine comprising a machine body, a spindle device, three posts, a sliding frame device and a tail ejecting device. The spindle device is installed on the machine body, and the top of the spindle device is provided with a joint platform accommodating a workpiece; the posts are distributed on the periphery of the spindle device and are provided with a longitudinal transmission device; the sliding frame device is connected to the longitudinal transmission device and comprises a frame body, a machining unit and a transverse transmission device, the frame body is in an integral triangular structure, and the transverse transmission device drives the machining unit to move on the frame body transversely; the tail ejecting device is arranged above the sliding frame device and corresponds to the spindle device in position. The spindle is not subject to partial load, the rigidity is high, the accurate cylindrical part spinning and forming are guaranteed, the centering performance of the machining unit during radial feeding is guaranteed, and difficulty in assembling and debugging is lowered.

Description

technical field [0001] The invention relates to the field of automobile parts manufacturing, in particular to a vertical spinning machine. Background technique [0002] With the development of society, all walks of life have higher and higher requirements for mechanical products, especially for automobile wheels, oil tanks, stainless steel tableware and other widely-demanded products, people require higher precision and strength. Products produced by traditional pressure forming technology have low precision and low surface finish, which cannot meet the technical requirements of high-precision fields, while the strength of products produced by traditional machining technology cannot meet technical requirements, especially in the fields of aviation, aerospace, automobiles, etc. There are higher requirements for product strength. [0003] The Chinese patent with the application number 200820167277.3 discloses a vertical powerful spinning machine. When the whole body is a fram...

[0003] The Chinese patent with the application number 200820167277.3 discloses a vertical powerful spinning machine. When the whole body is a frame, it occupies a large area. One set of spinning devices is respectively arranged on both sides and the rear side of the bed. When three sets When the spinning device processes the workpiece synchronously, the spindle is always subjected to an eccentric load in the radial direction, which causes the axis of the spindle to deviate and reduces the accuracy of the contour dimension of the processed part
