Numerical-control gravure double-head finish-turning machine

Abstract

The invention provides a numerical-control gravure double-head finish-turning machine. Double-guide slipways are arranged on the linear guides of a lathe bed worktable, and the double-guide slipways are connected with the linear guides via linear guide pairs, wherein a spindle box tailstock and a double-coordinate cross-shaped slipway which are arranged on each double-guide slipway are sequentially mounted; the spindle box tailstock is mounted on the inner side relative to each double-guide slipway, a customized chuck is arranged on the outer side of the spindle box tailstock, and a synchronous belt wheel is arranged on the inner side thereof, wherein a bull gear is arranged at the rear part of the customized chuck, and an electromagnetic clutch at the front end of the customized chuck is connected with the bull gear of the customized chuck via a pinion gear on the corresponding side of the customized chuck; and the double-coordinate cross-shaped slipway is mounted on the outer side relative to the double-guide slipway, and a tool rest is arranged on the corresponding side of the customized chuck. The invention can greatly improve the machining efficiency, guarantee the axiality of bores in secondary turning, ensure the high concentricity and good machining quality, facilitate the operation of a user and reduce the requirements for the skill of a worker.

Description

technical field [0001] The invention relates to the field of gravure plate-making processing, in particular to a numerically controlled gravure double-head finishing machine for secondary lathing inner holes. Background technique [0002] As far as the secondary turning inner hole is concerned, it belongs to finishing machining, and has higher requirements on the coaxiality of the holes at both ends, which makes the ordinary processing method have higher requirements on the quality of workers. [0003] At present, ordinary lathes are used in general plate making factories to turn the inner hole of the plate roller for secondary turning. Most of these lathes clamp one end of the steel pipe with a three-jaw chuck, and use the center frame to support the other end of the steel pipe. On one side, only the hole on one side can be turned, and when the other side is to be processed, it needs to be turned around and re-clamped, thereby increasing the time for the upper and lower pla...

Problems solved by technology

[0003] At present, ordinary lathes are used in general plate making factories to turn the inner hole of the plate roller for secondary turning. Most of these lathes clamp one end of the steel pipe with a three-jaw chuck, and use the center frame to support the other end of the steel pipe. On one side, only the hole on one side can be turned, and when the other side is to be processed, it needs to be turned around and re-clamped, which increases the time for the upper and lower plates, and the two-time clamping seriously affects the coaxiality of the two turnings of the inner hole of the steel pipe

If the quality of the workers is not high, not only the processing efficiency is low, but the accuracy cannot be guaranteed
