AI Technical Summary

Technical Problem

When machining large-diameter workpieces, conventional CNC roll lathes have a long front end of the cutter plate, and a long X-axis travel during retraction, resulting in poor cutter plate rigidity, easy chipping, and vibration affecting machining accuracy.

Method used

The design employs a combination of a tool post transverse feed mechanism and a tool plate transverse feed mechanism. A servo motor drives a ball screw and a reducer, which, combined with a stroke detection mechanism, enables automatic feeding of the tool plate. This ensures that the tool plate can move long distances without increasing the length of the lathe's transverse feed axis, thereby improving stability and accuracy.

Benefits of technology

Without increasing the length of the lathe's transverse feed axis, this method ensures a short blade overhang distance, good stability, avoids blade damage, improves machining accuracy, and facilitates the machining of the front and rear ends of the roll.

[0019] like Figures 1-5 As shown, an automatic tool feed device for a CNC roll lathe includes a base 1. A tool post transverse feed mechanism 2 is fixed inside the base 1. The tool post transverse feed mechanism 2 includes a first ball screw 21 rotatably mounted inside the base 1 and a first reducer 23 fixed to the end of the base 1. The power input end of the first reducer 23 is connected to a first servo motor 24, and the power output end of the first reducer 23 is connected to the first ball screw 21 via a first elastic coupling 22. A frame-type tool post 3 is slidably mounted on the ball sleeve of the tool post transverse feed mechanism 2 and mounted on the base 1. A slide rail supporting the frame-type tool post 3 is fixed on the base 1. Two dovetail grooves are formed on both sides of the frame-type tool post 3, and a set of dovetail guide rails 4 are fixed in each of the two dovetail grooves. The dovetail guide rails 4 are detachably fixed for easy replacement and maintenance. A front tool plate 6 and a rear tool plate 7 are slidably mounted in the two sets of dovetail guide rails 4, respectively. The 3 has two fixed blade transverse feed mechanisms 5. Each blade transverse feed mechanism 5 includes a second ball screw 51 rotatably mounted inside the frame-type blade holder 3 and a second reducer 53 fixed at the end of the blade transverse feed mechanism 5. The power input end of the second reducer 53 is connected to a second servo motor 54, and the power output end of the second reducer 53 is connected to the second ball screw 51 through a second flexible coupling 52. The front blade 6 and the rear blade 7 are respectively fixed to the ball sleeves of the two blade transverse feed mechanisms 5 by bolts. The two blade transverse feed mechanisms 5 can control the transverse feed of the front blade 6 and the rear blade 7 respectively, which is convenient for processing the two ends of the roll.
