Double-handstand turning center lathe

Abstract

The invention discloses a double-handstand turning center lathe. The double-handstand turning center lathe comprises a bed base; the bed base is provided with a standing column; the standing column is provided with a standing column guide rail; the standing column guide rail is connected with the lathe and a left-right handstand turning center; the lathe comprises a lathe carriage, a lathe sliding plate, a left work bench, and a right work bench; the lathe carriage is matched with the lathe sliding plate; the lathe sliding plate is provided with a lathe main shaft; a lathe tool changer at the front side of the lower part of the lathe main shaft is connected with the base; the left-right handstand turning center comprises a handstand turning center carriage, a handstand turning center sliding plate, and a handstand turning center main shaft; the lower part of the handstand turning center main shaft is connected with a handstand chuck; the base between the lathe main shaft and the handstand turning center main shaft is provided with a work bench base; the work bench is provided with a left clamping fixture; and the bed base is provided with a turning head. The double-handstand turning center lathe is capable of achieving the optimal matching of the turning and lathe time during the processing of the disc parts, saving the labor, reducing the manufacturing cost, and ensuring the precision and quality of the part production, the whole processing time is the shortest, and the production efficiency is high.

Description

technical field [0001] The invention relates to the technical field of numerical control machining centers, in particular to a double inverted turning center vertical machining. Background technique [0002] In the processing of various disc parts such as automobiles, such as bearing housing parts, see figure 1 , figure 2 , its size and outer diameter are mostly within a certain size range, such as between φ200mm-φ350mm, such parts often require precision turning on the internal hole system and both ends, and some threaded holes are distributed on one end surface of the plate edge, and the other Some counterbores and through holes are distributed on the end face, and the diameters of these threaded holes, counterbores and through holes are also different, which brings inconvenience to the processing of such parts. [0003] In the prior art, the process route for processing this kind of parts is generally: first use a CNC vertical lathe to turn the inner hole system, outer...

AI Technical Summary

Problems solved by technology

[0004] 1. The process time does not match. Generally speaking, the turning time of CNC vertical lathe is twice that of the drilling and tapping time of the machining center. To achieve the matching effect, the number of CNC vertical lathes must be doubled;

[0005] 2. After several times of clamping, the bearing holes at both ends turn around, and the processing is not easy to ensure the coaxiality requirements and dimensional accuracy;

[0006] 3. The iron filings are not easy to discharge when the CNC vertical lathe is turning the inner hole, and it is easy to cause the iron filings to scratch the surface of the finished inner hole and damage the machining accuracy;

[0007] 4. The number of transfer processes is large, and the auxiliary time is long, which greatly affects the production efficiency;

[0008] 5. A large number of machine tools and operators are required, which wastes human resources and increases manufacturing costs
