Long shaft double-head turning and clamping drive device and method

Abstract

The invention discloses a long shaft double-head turning and clamping drive device and method. The long shaft double-head turning and clamping drive device comprises a left clamping unit, a right clamping unit and a power drive unit. A left clamping drive unit and a right clamping drive unit are installed on sliding blocks of a guide rail of a rack through a left main shaft box and a right main shaft box. A left Z-axis drive unit is arranged under the left clamping drive unit, a right Z-axis drive unit is arranged under the right clamping drive unit, and the power drive unit is installed on the side face of the left main shaft box. The long shaft double-head turning and clamping drive device has the advantages that the traditional mode of two-time clamping and two-time machining is replaced, and the production efficiency and capacity are improved; the clamping point of a long shaft component is clamped commonly through a left hydraulic power chuck and a right hydraulic power chuck, and flexibility can be achieved conveniently according to machined components of different sizes; the same power drive unit is adopted in left clamping unit and the right clamping unit, the long shaft component is commonly clamped, the clamping rigidity of the long shaft component is improved, and synchronism is good.

Description

Problems solved by technology

[0002] In the current domestic and foreign automobile industry, before the forming and processing of a certain part involving a large number of applications, the raw material is a typical ultra-slender part. This part has an insurmountable processing technology, low processing accuracy, and poor product processing consistency. Bottleneck of inefficient production

At present, in China, the processing of the above-mentioned parts is usually completed by the numerical control transformation of ordinary lathe equipment. The processing method is to turn one end of the part; disassemble the part, turn around and clamp again, and turn the other end. low efficiency

In foreign countries, special equipment is usually developed according to the part technology for processing, automatic feeding and automatic clamping, but the price is very expensive

[0003] In view of the above problems, a slender shaft double-head turning clamping drive device and its method are proposed, which effectively solve the problems of insufficient clamping rigidity and low machining accuracy of slender parts, resulting in poor consistency of product processing and low production efficiency. , has broad prospects in the field of machining, manufacturing and automation
