Embodiment 1

[0026] see Figure 1-Figure 5 , the embodiment of the present invention provides a numerically controlled machine tool for processing broken line rope grooves, which includes a frame 5 , a cutting assembly 3 , a control assembly and a profiling assembly 4 .

[0027] The frame 5 is provided with a main shaft 1 driving part and a feed driving part, wherein the main shaft 1 driving part is used to drive the main shaft 1 of the CNC machine tool to rotate, and during the processing, the main shaft 1 is used to connect with the workpiece to be processed , resulting in the main motion of the cutting process. The feed drive is used to drive the cutting assembly 3 to generate feed, retract and move motions. The control assembly is connected with the driving part of the main shaft 1 and the feeding driving part, so as to control the rotation of the main shaft 1 and the movement of the cutting assembly 3 . Specifically, the driving part of the spindle 1 includes a servo motor, the feed...

Embodiment 2

[0057] The embodiment of the present invention provides a numerically controlled machine tool for processing broken line rope grooves. The difference between it and the numerically controlled machine tool in Embodiment 1 is that in Embodiment 1, a sensor and a profiling drive are provided, and the sensor and The control assembly is connected, and the control assembly controls the profiling driving part to achieve the relative angle between the profiling part and the main shaft 1, and to ensure that the bending section of the folding line on the rope groove occurs at a specific circumferential angle; and in this embodiment In , the above functions are realized in the following ways:

[0058] In this embodiment, the CNC machine tool includes a transmission assembly (not shown in the figure), which is used to connect the driving part of the main shaft 1 and the profiling shaft 41 . When the active 1 driving part drives the workpiece to rotate, it simultaneously drives the profili...

Abstract

The invention relates to the field of numerical control machine tools, and specifically relates to a numerical control machine tool for machining a winding drum broken line rope groove and a machiningmethod. The numerical control machine tool comprises a rack, a cutting assembly, a control assembly and a profiling assembly, wherein the cutting assembly is arranged on the rack, and the profiling assembly is arranged on the rack; the cutting assembly comprises a tool rest and a sliding piece, and the tool rest is connected with the sliding piece; the profiling assembly comprises a profiling block, a profiling part is arranged on the profiling block, the outline of the profiling part is used for corresponding to the shape of the to-be-machined broken line rope groove; and the profiling partis used for applying thrust to the sliding piece. When the numerical control machine tool is adopted for machining the winding drum rope groove, the beneficial effects of convenient mounting, low labor cost and high machining efficiency of a numerical control lathe can be reserved, a broken line inflection on the rope groove is generated in the manner that the profiling assembly enables a tool togenerate orbital transfer, accordingly, a motor rotating forwards and backwards does not need to be arranged for driving the tool to do reciprocating motion, and cost can be better reduced.

Description

technical field [0001] The invention relates to a numerically controlled machine tool, in particular to a numerically controlled machine tool and a processing method for processing broken line rope grooves of drums. Background technique [0002] The broken line rope groove is a rope groove form imported from abroad that is suitable for multi-layer winding of steel wire ropes. This kind of rope groove remains parallel to the end face of the flange on most of the sections in the circumferential direction of the drum, and only intersects with the end surface of the flange on a very small section, so the rope groove must appear inflection phenomenon. Due to the special structure of this rope groove, it cannot be directly processed by traditional ordinary lathes. In the prior art, numerically controlled lathes are usually used to process broken line rope grooves. When using the existing technology to process the broken line rope groove, usually on the basis of setting the spind...
