Abstract

The utility model relates to a digital control spiral bevel gear milling machine which mainly comprises a bed piece, a bed saddle, a work piece box and a knife tool box, wherein an X shaft rail is fixedly arranged on the bed piece, and an upright post is connected with the bed piece glidingly via the X shaft rail. One side of the upright post is fixedly provided with a Y shaft rail, and the knife tool box is glidingly connected with the upright post via the Y shaft rail. A knife tool main shaft is arranged in the knife tool box, and the bed saddle is connected with the bed piece glidingly via a Z shaft rail. The work piece box is connected with the bed saddle glidingly via a curl plate, and a work piece main shaft is arranged in the work piece box. The utility model has the advantages that the part categories and the drive mechanisms of the existing gear milling machine are effectively reduced, production cost is saved, the time of adjustment is shortened, the labor intensity of operating staffs is reduced, drive mechanisms are simplified, the transmission of a drive shaft is simple, and transmission efficiency and accuracy are improved. The standard performed by the digital control spiral bevel gear milling machine is one-grade higher than the national standard performed by the existing gear milling machine, and the same gear milling machine can be used for cutting and extending two gears with different gear cogs, such as a spiral bevel gear and an external cycloidal gear.

Description

Numerical control spiral bevel gear milling machine arrangement

Technical field

The utility model belongs to gear working machine, particularly relate to a kind of simple in structure, can improve transmission efficiency and transmission accuracy and be applicable to the numerical control spiral bevel gear milling machine arrangement of the different tooth system gears of processing.

Background technology

Present known numerical control spiral bevel gear milling machine is made up of several parts such as lathe bed, cage chair, cage chair support, feed mechanism, workpiece boxs, the mill teeth machine that wherein has is equipped with the tilt structure, what have is not with the tilt structure, above-mentioned lathe mechanism complexity, a machine tool is formed by thousands of parts, the transmission mechanism of She Zhiing is many simultaneously, therefore make the operation of complete machine when assembling and debugging more loaded down with trivial details, because transmission mechanism is many, driving error therebetween also increases thereupon, cause transmission accuracy to reduce, its cutting precision is at the 6.5--6 of existing national standard inter-stage; When the mill teeth machine need cut the gear of different parameters, lathe such as change gear, the angle of revolution of workpiece box, horizontal position of wheel and workhead offset etc. be must adjust, thereby trouble and labour intensity increased to operating personnel, and time-consuming, effort, production and processing cost height.

The utility model for solve the technical problem that exists in the known technology provide a kind of have simple in structure, can improve transmission efficiency and transmission accuracy and be applicable to the numerical control spiral bevel gear milling machine arrangement of the different tooth system gears of processing.

The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:

Numerical control spiral bevel gear milling machine, mainly comprise lathe bed, saddle, workpiece box and toolbox, on lathe bed, install the X-axis guide rail, column is by X-axis guide rail and lathe bed and is slidingly connected, be fixed with the Y-axis guide rail in column one side, toolbox is by Y-axis guide rail and column and is slidingly connected, cutter spindle is installed in toolbox, saddle is and is slidingly connected by being fixed on Z axis rail on the lathe bed and lathe bed, workpiece box is and is slidingly connected by being fixed on arc on the saddle and saddle, and work spindle is set in workpiece box.

Advantage and the good effect that the utlity model has are: this mill teeth machine is owing to adopted above-mentioned new layout, promptly use X respectively, Y two linear axis replace the cage chair part, use X, the interlock that Y-axis adds the B axle replaces the tilt structure, and each motion parts of mill teeth machine adopts numerical control control, the part classification and the transmission mechanism of present mill teeth machine have then effectively been reduced, the mill teeth machine is unworthy of change gear, promptly saved production cost, reduced the adjustment time again, alleviated labor intensity of operating personnel, owing to simplified transmission mechanism, the oil site of lathe reduces relatively, the power transmission shaft transmission is simple, can improve transmission efficiency and transmission accuracy, the national standard of carrying out than present known mill teeth machine improves a grade, on a mill teeth machine by above-mentioned each motion and the variation of control program, can the cutting arc bevel gear and extend the gear of two kinds of different tooth systems of epicycloidal gear.
