Abstract
The utility model relates to a center hole slotting apparatus which is positioned inside the lathe spindle hole and comprises a hydraulic chuck which is provided on the lathe spindle, and a rolling guide unit which includes a bearing seat, a bearing and a guide sleeve, wherein the rolling guide unit is provided on the center of the hydraulic chuck, the bearing seat is fixed on the chuck body of the hydraulic chuck, the bearing is positioned inside the bearing seat, the external diameter of the guide sleeve is engaged with the bore of the bearing while the internal diameter of the guide sleeve is engaged with the guide portion of an auger stem which is positioned inside the hollow draw tube hole of the spindle, the front end of the auger stem is supported and guided by the guide sleeve while the rear end of the auger stem is connected with the piston rod of a cylinder through a locating pin, the cylinder is fixed on the machine body through a bearer, the center hole drill is positioned inside the taper hole in the front end of the auger stem. The utility model has the advantages that the processed center hole is high coaxial with the bore or the excircle which is turned from the other end of the work-piece, and the accuracy is highly preserved.
Description
Affiliated technical field
The utility model relates to a kind of centering device that is built in the lathe spindle hole, after this device is installed on the lathe, especially is fit to automobile industry piston car seam centering operation.
Background technology
At present, state's used lathe of inner carrier processing industry piston car seam centering operation is the import lathe, and its centering device and main shaft integrate, and specificity is strong, but complex structure, maintenance difficult, precision stability is poor, costs an arm and a leg.
Summary of the invention
The purpose of this utility model be to overcome the deficiencies in the prior art and provide a kind of put can be on original lathe convenient install be built in centering device in the lathe spindle hole, the fairlead of this device drilling rod and block bearing are installed in the endoporus of hollow chuck, the oil cylinder that promotes the drilling rod feeding and retreat is installed on the carriage of body of lathe bed end face, the oil cylinder piston bar links together by straight pin and drilling rod, can be implemented in when carrying out the turning of the part other end, finish the processing that part is held the end centre bore.
The purpose of this utility model is achieved in that and comprises the oild chuck that is installed on the lathe spindle, the rolling pilot unit of forming by bearing block, bearing and fairlead, the rolling pilot unit is installed in the center of oild chuck, bearing block is fixed on the chuck body of oild chuck, bearing is installed in the bearing block, the external diameter of fairlead cooperates with the endoporus of bearing, and the internal diameter of fairlead cooperates with the guiding position of drilling rod
Drilling rod is installed in the main shaft hollow trombone slide hole, and front end is supported and guiding by fairlead, and the rear end is connected with the piston rod of oil cylinder by alignment pin, and oil cylinder is fixed on the body of lathe bed by carriage, and centre drill is installed in the taper hole of drilling rod front end.
Oild chuck is installed on the lathe spindle, its claw can be under the driving of angling cylinder clamping work pieces, workpiece is rotated with lathe spindle.
Oil cylinder is fixed on the body of lathe bed by carriage, finishes the feeding of drilling rod and returns action by hydraulic-driven.
The utlity model has following advantage:
1. endoporus or outer circles height that centre bore that processes and the turning of the workpiece other end go out.
2. because the fairlead and the block bearing of drilling rod is installed in the endoporus of hollow chuck, and fairlead adopted antifriction self-lubricating material, so this device has the good advantage of precision stability.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises the oild chuck 2 that is installed on the lathe spindle 3, the rolling pilot unit of forming by bearing block 4, bearing 5 and fairlead 13, the rolling pilot unit is installed in the center of oild chuck 2, bearing block 4 is fixed on the chuck body of oild chuck 2, and bearing 5 is installed in the bearing block 4, and the external diameter of fairlead 13 cooperates with the endoporus of bearing 5, the internal diameter of fairlead 13 cooperates with the guiding position of drilling rod 8
Drilling rod 8 is installed in the main shaft hollow trombone slide hole, and front end is supported and guiding by fairlead 13, and the rear end is connected with the piston rod 12 of oil cylinder 10 by alignment pin 11, and oil cylinder 10 is fixed on the body of lathe bed by carriage 9, and centre drill 7 is installed in the taper hole of drilling rod 8 front ends.
Oild chuck 2 is installed on the lathe spindle, its claw 6 can be under the driving of angling cylinder clamping work pieces 1, workpiece is rotated with lathe spindle.
Oil cylinder 10 is fixed on the body of lathe bed by carriage 9, finishes the feeding of drilling rod and returns action by hydraulic-driven.Because drilling rod 8 self do not rotate, and workpiece is clamped in and rotates with main shaft on the oild chuck 2, and centre drill 7 relative workpiece produce relative rotary motion, thus the realization drilling function.
