Numerical control lathe for processing worm gears

Abstract

A numerical control lathe for processing worm gears comprises a lathe bed, a gearbox at one end of the lathe bed, a worm gear hob and a first planker, wherein a spindle is arranged in the gearbox; a spindle encoder is mounted on one side of the gearbox; a numerical control system in circuit connection with the spindle encoder is arranged at the upper part of the gearbox; a tail stock is arranged on the other side of the lathe bed; an apex is mounted on the tail stock; one end of the worm gear hob is mounted in a taper hole of the spindle; the other end of the worm gear hob is butted with the apex; the first planker is arranged in the middle of the lathe bed; a first stepping motor and a feeding planker matched with the first planker are arranged on the first planker; the feeding planker and the first stepping motor are connected with each other through a horizontal feeding screw rod; a rotary table and a rotary stepping motor in circuit connection with rotary table are arranged on the feeding planker; and the rotary stepping motor is in circuit connection with the numerical control system. The numerical control lathe has the advantages that the processing of the worm gears is fulfilled on the numerical control lathe; enterprises' acquisition costs are reduced; the problem that the conventional hobbing machine processing index error is difficult to eliminate is solved; and the machining precision is greatly improved.

Description

technical field [0001] The invention belongs to the field of numerically controlled lathes, in particular to a numerically controlled lathe used for machining worm gears. Background technique [0002] CNC lathes, also known as CNC lathes, are currently the most widely used CNC machine tools in China, accounting for about 25% of the total number of CNC machine tools. CNC lathe is a mechatronics product integrating many technologies such as machinery, electricity, hydraulic pressure, pneumatic, microelectronics and information. As a high-precision and high-efficiency automatic machine tool, it has a wide range of processing performance and can process straight lines Cylinder, slanted cylinder, arc and various threads. At present, the existing worm gear processing is generally operated on the hobbing machine, but the cost of repurchasing the hobbing machine is high, and the indexing error of the mechanical transmission mode of the hobbing machine is difficult to eliminate.
