Abstract

The utility model relates to a special power head for and end surface of a numerical control boring machine. The special power head comprises a power head consisting of a motor, a transmission case, a main shaft box, a main shaft and a cutter head body. The main shaft box of the main shaft is fixedly supported at the front part of the transmission case. The cutter head body is installed at the front end of the main shaft. A connecting flange is fixedly arranged at the rear part of the transmission case. A servo motor is arranged at the rear end of the connecting flange. The main shaft of the servo motor is in gapless connection with a ball screw in the connecting flange through an expansion sleeve coupling. The ball screw is connected with a pushrod arranged in the main shaft through a coupling. The front end of the pushrod is connected with a rack and pinion. The rack and pinion is connected with the transverse feeding device of the cutter head body. The transverse feeding of the cutter head body is realized through the drive of the servo motor at a tail end, the machining of the step end surface of the entire workpiece boring machine is completed in one step of clamping, the dimension accuracy of a plane rabbet is effectively guaranteed, the situation of frequent cutter replacement is avoided, the production efficiency is improved and the labor intensity is reduced.

Description

Numerical control bore hole face work custombuilt power unit
Technical field
The utility model relates to a kind of numerical control bore hole face work custombuilt power unit, is used for the numerical control bore hole face work of machining large vehicle bridge axle housing.
Background technology
The transmission processing technology of vehicle bridge axle housing is on horizontal boring machine, work piece positioning tight after, through changing thick, fine boring tool, change friction speed and the amount of feeding is successively accomplished slightly, the operation of right boring hole, scraping end surface.Need frequent change cutter and speed, manufacturing procedure is long, and labour intensity is big, and efficient is low, and processing cost is high, is not enough to guarantee the completion of production task, and difficulty of processing is bigger during especially for the step plane, and efficient is lower.
Summary of the invention
The purpose of the utility model provides a kind of numerical control bore hole face work custombuilt power unit; Be converted into the rectilinear motion of digital control system control the radial motion of cutterhead; The positioning accuracy and the repetitive positioning accuracy that possess digital control system control overcome the deficiency that has boring head now, can not effectively guarantee the technical barrier that stepped diameters dimensional accuracy and flatness require when solving plane, original hydraulic pressure boring head ride rank; Enhance productivity and machining accuracy, cut down finished cost.
The purpose of the utility model realizes as follows: this numerical control bore hole face work custombuilt power unit; Comprise the unit head that constitutes by motor, gearbox, main spindle box, main shaft, cutter head, the main spindle box of the anterior fixed support main shaft of gearbox, the fore device cutter head of main shaft; Dish is fixedly connected at the gearbox rear portion; Tie-plate back-end device servomotor, servomotor main shaft do not have the gap through expansion set shaft coupling and ball-screw in the tie-plate and connect, and ball-screw connects with the push rod that installs in main shaft through shaft coupling; Push rod front end attachment tooth rack-and-pinion; Rack-and-pinion connects the cross feed device of cutter head, and rack-and-pinion adjutant's circular motion transfers rectilinear motion to, drives thus that cutter head is horizontal to be advanced.
The utility model is realized crossing feed of cutter head through the driving of tail end servomotor; A clamping is accomplished the processing of whole work-piece bore hole ride rank end face, effectively guarantees plane seam dimensional accuracy, avoids the frequent change cutter; Improve production efficiency, and alleviated labour intensity.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
With reference to Fig. 1; Constitute unit head by motor, gearbox 3, main spindle box 4, main shaft, cutter head 5, the main spindle box 4 of gearbox 3 anterior fixed support main shafts, the fore device cutter head 5 of main shaft; Dish 2 is fixedly connected at gearbox 3 rear portions; Tie-plate 2 back-end device servomotors 1, servomotor 1 main shaft do not have the gap through the expansion set shaft coupling with tie-plate 2 interior ball-screws and connect, and ball-screw connects with the push rod of device in main shaft through shaft coupling; Push rod front end attachment tooth rack-and-pinion, rack-and-pinion connects the cross feed device of cutter head 5.
