Embodiment Construction

[0034] In order to make it easier for those skilled in the art to understand the present invention, the specific implementation manners of the present invention will be described below with reference to the accompanying drawings.

[0035] Such as Figure 1-8 As shown, the present invention provides a CF-type servo interpolation shaft spindle device for CNC lathes, which realizes fast and precise meshing of the driven gear plate 14 and the transmission gear 232, so as to change the rotation speed of the spindle 17, the gear Combined, the rotation of the main shaft 17 is converted from the main shaft motor drive to the motor 24 drive on the CF shaft mechanism 2, so that the main shaft 17 can be interpolated with other feed axes to process the contour curve, and the main shaft 17 can be turned, milled, drilled, tapped, The working status of various processing techniques such as silk.

[0036] Technical scheme of the present invention is:

[0037] The invention provides a CF typ...

Abstract

The invention provides a CF type servo interpolation shaft main shaft device for a numerical control lathe. The CF type servo interpolation shaft main shaft device comprises a lathe main shaft, a CF shaft mechanism, a brake mechanism and an encoder mechanism. The CF shaft mechanism, the brake mechanism and the encoder mechanism are arranged on the lathe main shaft; the CF shaft mechanism comprises an oil cylinder, a protective cover, a fixed seat and a motor; the oil cylinder, the protective cover and the motor are fixed on the fixed seat; a transmission shaft, a transmission gear and a speed reducer are arranged in the fixed seat; one end of the transmission shaft is connected with the speed reducer, and the speed reducer is connected with the motor; and the transmission gear is fixed to the transmission shaft, a shifting block and a guide shaft are arranged on the oil cylinder, the free end of the oil cylinder is connected with the guide shaft, and a shifting block is arranged outside the guide shaft. According to the CF type servo interpolation shaft main shaft device for the numerical control lathe, the rotation speed of the lathe main shaft is adjusted by arranging the CF shaft mechanism, so that the whole device adapts to different working modes.

Description

technical field [0001] The invention relates to the field of a CF type servo interpolation axis spindle, in particular to a CF type servo interpolation axis spindle device for a numerically controlled lathe. Background technique [0002] As one of the important hardware in CNC lathe, the main shaft is usually composed of bearings and transmission parts, which drives the workpiece to rotate. The conventional main shaft can only be used as a rotating shaft to hold the workpiece for rotation, and the tool performs rotary cutting on the workpiece. The difference between a CNC lathe and a milling machine is that the lathe is used to process the parts of the revolving body. The turning tool cuts off the product shape according to the generatrix of the revolving body. The milling machine uses a high-speed rotating milling cutter to cut out the required shape and features on the blank. With the improvement of product production efficiency, the processable process of CNC lathes is in...
