Abstract
The utility model relates to a multifunctional combined thread cutter head which belongs to thread cutting tools. The utility model comprises a transitional sleeve tube, a thread chaser, and a screw for fixing a thread chaser carrier. The utility model is characterized in that a drill sleeve is arranged in a straight through hole at a handle of the thread chaser carrier, and a drill bit is arranged in the drill sleeve; the transitional sleeve tube and the holder of the thread chaser carrier are respectively provided with a screw hole, and a fastening bushing screw is screwed in the two screw holes. The utility model changes two machines with two working procedures to one machine with one working procedure for machining a work piece which needs both outer thread cutting and radiusing, so labor and equipment are saved, and the labor productivity is improved.
Description
The utility model belongs to the positive thread cutter.
At present, the standard crop that the cutting external screw thread is used, mainly formed by chaser frame, hold-down ring, adjustment ring, chaser jaw, transition sleeve, retaining thread chasing tool frame screw, the structure of this die head and principle can see 460 pages to 499 pages of " screw tool " books that China Machine Press in 1986 publishes for details, this book is by Xiao Shigang, Dong Renyang, Gao Zelie chief editor, uses above-mentioned die head can only be used to cut external screw thread.
The purpose of this utility model provides a kind of multifunction combined die head, make it not only can the cutting external screw thread, and can also be in the cutting gas thread, finish the chamfering process of workpiece endoporus, thus make not only must threading but must in the workpiece of Hole chamfering merge into the processing of a machine tool one procedure by former two lathe two procedures processing.
For achieving the above object, the utility model has adopted a kind of multifunction combined die head, but this die head is installed on the machine tool chief axis of threading by transition sleeve.The multifunction combined die head of the utility model comprises the screw of transition sleeve, chaser frame, hold-down ring, adjustment ring, chaser jaw, chaser, retaining thread chasing tool frame, the multifunction combined die head of the utility model is characterised in that: in chaser frame shank clear opening, the drill bit lining is housed, in the drill bit lining drill bit is housed, at transition sleeve and chaser frame shank a screw hole is arranged respectively, have a trip bolt to be screwed in these two screw holes.Before the processing, earlier the chaser frame is transferred to processing external pipe thread desired location, again chaser frame trip bolt is tightened up, when then lining being transferred to the workpiece of falling external pipe thread interior angle desired location together with drill bit, with the tight bushing screw-driving, at this moment, lining is tightened up again.Like this, when machine tool chief axis moved down, in the time of can guaranteeing that the chaser threading finishes, Hole chamfering was also finished simultaneously in the external pipe thread workpiece, thereby realized the invention task.
The advantage of the multifunction combined die head of the utility model is, cutting external screw thread and the interior angle that falls are merged into the processing of a machine tool one procedure to the external pipe thread workpiece that endoporus is needed chamfering respectively by original two lathes, this had both saved equipment, personnel, kinetic energy, had improved labor productivity again greatly.
Fig. 1 is the structure and the duty cutaway view of the multifunction combined die head of the utility model.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
The utility model shown in Figure 1 is the embodiment that 30.300 type standard thread crops is improved design.The structure of each parts of standard thread crop sees preamble described " screw tool " book for details.
As shown in Figure 1, the described multifunction combined die head of the utility model embodiment is made up of transition sleeve 9, chaser frame 14, hold-down ring 15, adjustment ring 16, chaser jaw 19, chaser 3, drill bit 13, drill bit lining 10, stationary bushing screw 12, retaining thread chasing tool frame screw 11.This multifunction combined die head is installed on the machine tool chief axis 8 of machining screw workpiece by transition sleeve 9, and the shank of chaser frame 14 is contained in the transition sleeve, and main effect is by chaser jaw 19 chasing tool 3 to be installed; Hold-down ring 15 matches with chaser frame 14, is used to control closing up and opening of chaser 3; Adjust ring 16 and be contained in the hold-down ring 15, be used to adjust the size of work piece 2 screw threads; Chaser jaw 19 is contained in chaser frame 14 heads, is used to install chasing tool 3; Lining 10 profiles are cylindrical, and endoporus still is taper, and this lining is contained in the chaser frame 14 shank clear openings; At transition sleeve 9 and chaser frame 14 shanks a screw hole is arranged respectively, and have the screw 12 of a tight bushing 10 to be screwed in these two screw holes, screw 12 also plays retaining thread chasing tool frame 14 simultaneously.
The duty of the multifunction combined die head of the utility model is described below in conjunction with accompanying drawing 1.
Before processing; the operator at first installs chaser; (drill bit transfers to when workpiece 2 external screw thread completion of processing chaser frame 14 and lining 10 to be transferred to the workpiece to be machined desired location again; workpiece 2 interior Hole chamferings are completion of processing also); and will be installed on the pillar 7 closing up the ring 6 with expanded loop 4 transfer to desired location, workpiece 2 is installed on the Drilling machines bench by magic chuck 1.
Start drilling machine; drill press spindle 8 rotations; when the operator moves Handl eof drill press and moves down; drill press spindle drives multifunction combined die head and moves down; when chaser 3 moves to workpiece 2 upper ends with drill press spindle 8; chaser 3 beginning cutting external screw threads; workpiece 2 external screw thread completion of processing, interior Hole chamfering are the while completion of processing also, at this moment; shift fork 5 bumps to expanded loop 4; chaser 3 is opened, move when the operator operates on the drill press spindle 8, shift fork 5 bumps to closing up ring at 6 o'clock; chaser 3 has promptly entered the original state of next impulse stroke for closing up state.
