Abstract

A manufacturing method for a sleeve pipe mounted on a middle planker comprises the following steps: 1, cylinder processing: blanking, large end cutting and small end cutting, small end excircle gear grinding allowance and inner hole cutting, and taper hole gear grinding, bolt hole drilling, heat treatment and fine inner hole grinding; 2, seat processing: casting, scribing, bottom surface peeling, inner hole cutting and fine boring, and threaded hole drilling and tapping; 3, drilling and tapping on the large slide carriage of a lathe by using a motor drill, and fixing a positioning plate; 4, fixing a support in a proper position of the middle planker of the lathe; 5, mounting a set screw at the slotted long cylindrical post end on the support by using a nut for locking, and propping the cylindrical end of the bolt on the positioning plate; 6, fixing the seat onto the middle planker of the lathe so as to enable the axial line of the inner hole of the seat to be basically coaxial with the rotation axis of the main shaft of the lathe; 7, clamping a boring bar onto the main shaft of the lathe, the feeding a cutter into the middle planker and finely boring the inner hole of the seat; 8, grinding the excircle of the small end of the cylinder according to the dimension of the finely bored seat so as to enable the match of the cylinder and the inner hole of the seat to be H7/h6; 9, fixing the cylinder into the inner hole; and 10, fixing a hand wheel onto a lead screw and mounting the lead screw into the screw hole of the cylinder. The manufacturing method is simple, scientific and low in cost, and has high economic benefits.

Description

Be contained in the manufacture method of the sleeve on the middle carriage

Technical field

The present invention relates to relate to the metal working machine tool annex, especially be contained in the manufacture method of the sleeve on the middle carriage.

Background technology

The master worker of machinery industry knows: will use drill bit, cornish bit and reamer to part boring, reaming or fraising on lathe, and these cutters are mounted in all in the taper hole of tail stock sleeve, change according to the needs of operation.In practical operation, a kind of cutter of every use will manually exert oneself to come and go mobile tailstock, and artificial hand rotates handwheel, wastes time, and labour intensity is big.The main precision that is contained in the sleeve on the middle carriage is axis and the lathe spindle rotation almost coaxial of the endoporus of its mounting cutter, and wants to reach this purpose with common method: become whole part processing assembling to be difficult to accomplish.

Summary of the invention

The purpose of this invention is to provide a kind of sleeve and manufacture method that is contained on the middle carriage, finish the fine finishining of an endoporus with the autofeed of the power of lathe spindle and lathe big cargo chute, coaxial with the lathe spindle rotation with the axis of the taper hole of the mounting cutter of guaranteeing the cutter tube.

The objective of the invention is to realize as follows:

Be contained in the manufacture method of the sleeve on the middle carriage: 1. the processing of cutter tube: the big end cylindrical of blanking → car and end face → car small end cylindrical and end face, the small end cylindrical stays mill amount → car endoporus, and taper hole stays mill amount → drilling screw hole → heat treatment: 48～52HRC → correct grinding endoporus.2. Zuo processing: right boring amount → bore, attack left end screwed hole is stayed in cast blank → line → sole face → car endoporus and both ends of the surface, endoporus.In the appropriate location of lathe big cargo chute with electric hand drill boring, tapping, with screw, spring washer location-plate is fixed on the lathe big cargo chute; 4. support is fixed with screw, spring washer in the appropriate location of lathe middle carriage; 5. the oval styletable holding screw of fluting is contained in the screw of support with the slot cylindrical end of oval styletable holding screw of nut check and withstands on the location-plate; Seat with plain washer, spring washer, taper pin with internal thread be bolted on the lathe middle carriage, make axis and the lathe spindle rotation almost coaxial of the endoporus of seat; 7. boring bar is clamped on the chuck of lathe spindle, with the feed of lathe middle carriage, the endoporus of right boring seat; 8. making the cooperation of the endoporus of cutter tube and seat by the small end cylindrical of the size grinding cutter tube after the seat right boring is H7/h6; 9. the cutter tube is fixed in the present endoporus with slotted cheese head screw and spring washer; 10. handwheel is fixed on the cylinder on the leading screw left side with general flat key and fluting socket cap axial screw, and the double-screw bolt on leading screw the right is contained in the screw of cutter tube.

Originally the advantage that is contained in the manufacture method of the sleeve on the middle carriage is: finish the fine finishining of an endoporus with the autofeed of the power of lathe spindle and lathe big cargo chute, and coaxial with the lathe spindle rotation with the axis of the taper hole of the mounting cutter of guaranteeing the cutter tube.Be contained in sleeve on the middle carriage and change fast in can the cutter tube on being contained in the lathe middle carriage cutter that processing needs is installed, utilize the motor-driven feed function of lathe, finish processing to the hole with corresponding cutter, laborsaving fast.The manufacture method that is contained in the sleeve on the middle carriage is simple, science, precision height.
