Abstract
An automatic reverse tapping device mainly comprises a main shaft, a main shaft gear, a transmission gear, a drill shaft, a rotating shaft gear, a friction device, a positioning rod and the like, and can automatically control the forward and reverse rotation of a tap through mechanical transmission to continuously complete the whole tapping process at one time. The utility model relates to a rationally, convenient operation, the machining precision is high, has solved defects such as through-hole, blind hole in the production, can be supporting with all kinds of drilling machines, extensively is used for the spare part processing and the mill maintenance of each trade.
Description
The utility model is automatically to reverse thread tapper, belongs in the mechanical industry and the supporting special-purpose tapping utensil of all kinds of drilling machines.
Existing tapping is mainly finished tapping by drilling machine under electric elements control except that manual, manual tapping is big because of labour intensity, and efficient is low very inapplicable; The drilling machine tapping of electric elements control is to set up one to control tapping along contrary electric switch and withdraw from a hole with the clockwise tapping and the reverse of screw tap on drilling machine, but the error that in practical operation, causes because of the hand-guided electric switch, be difficult to make workpiece to reach required precision, very easily cause the defect such as through hole, blind hole of workpiece, also influence the service life of screw tap.
The purpose of this utility model provides a kind of reasonable in design, machining accuracy height, special-purpose tapping utensil easy and simple to handle.
The utility model is to reverse thread tapper automatically, mainly by housing (13), and main shaft (1), mainshaft gear (3), travelling gear (4), auger spindle (6), auger spindle gear formations such as (5).During work, rotation along with main shaft (1) and mainshaft gear (3), auger spindle (6) drives auger spindle gear (5) by travelling gear (4), reverse with respect to main shaft, or directly drive clockwise acting on the screw tap (9) by main shaft (1), in tapping, put, be respectively when replying clockwise, idle running, reverse state in place, finish whole tapping process automatically.
When auger spindle (6) is directly driven when clockwise by main shaft (1), can connect or the mode that directly main shaft (1) is inserted in the auger spindle (6) connect auger spindle (6) and main shaft (1) by strigil (12); For guaranteeing the accuracy of work-piece tapping size, on housing, also backstay (8) can be housed simultaneously; In addition, stressed evenly for making the utility model in when work, can be by preventing further fixing thread tapper of swing arm (10).
Accompanying drawing has provided the structural representation of the utility model two types.
Fig. 1 is the direct-connected thread tapper structural representation of main shaft and auger spindle;
Fig. 2 thread tapper structural representation that to be main shaft be connected with strigil with auger spindle.
Below in conjunction with embodiment the utility model is further described;
1, install: earlier thread tapper main shaft (1) is placed on the power transmission shaft of bench drill and embedding tight, regulate the length of anti-swing arm (10) again and withstand on the column of bench drill, can not swing when guaranteeing thread tapper work;
2, prepare: the drill point (7) that screw tap (9) will be housed is placed in auger spindle (6), and upward also embedding is tight, and is also fixing by the length of the required tapping degree of depth requirement adjusting backstay (8) of workpiece then;
3, tapping: start bench drill, and thread tapper is advanced to workpiece, main shaft (1) rotation under power transmission shaft drives, when screw tap (9) with before surface of the work does not contact, the clockwise of main shaft (1) acts on auger spindle gear (5) by mainshaft gear (3) through travelling gear (4), and the screw tap (9) that drives on the auger spindle (6) is the reverse state; When the screw tap contact workpiece, auger spindle (6) moves on slightly because of the top power on worker uncle surface, makes auger spindle (6) break away from auger spindle gear (5), the of short duration idle running of screw tap (9); And then auger spindle (6) is gone up Mobile Communication again and is crossed strigil (12) and link to each other with main shaft (1), makes screw tap (9) clockwise with the rotation of main shaft (1), the beginning tapping.
4, reply: when tapping during to desired depth, backstay (8) props up surface of the work, because tapping pressure is eliminated, the strigil (12) on the auger spindle (6) breaks away from main shaft (1), and auger spindle moves down slightly, makes the of short duration idle running of screw tap (9); And then auger spindle (6) continues to be displaced downwardly on the auger spindle gear (5), and the effect by travelling gear (4) reverses auger spindle (6), drives screw tap and withdraws from a hole automatically.
More than be the embodiment of the automatic reverse thread tapper of band strigil (12), as select the thread tapper of no strigil for use, can on main shaft (1) and auger spindle (6), set up spring (2), (11) respectively, auger spindle (6) can be moved up and down more neatly, drive screw tap and do contrary, empty, suitable, empty, contrary rotation, finish whole tapping process.
The utility model compared with prior art has following outstanding advantages and good effect:
1, easy and simple to handle, the machining accuracy height, pass through machine driving, can automatically control rotating along contrary continuously of screw tap, once finish whole tapping process, greatly alleviate labour intensity, simultaneously, solve the defects such as through hole, blind hole in the production, can guarantee the machining accuracy that workpiece is required, increased substantially quality and the production efficiency of product.
2, reasonable in design, long service life, the critical piece of this thread tapper select the high-test metal material through car, mill, the technology such as mill and heat treatment process form, practical, wear-resisting, support the use with all kinds of drilling machines, can be widely used in parts machining and the factory repair of instrument, lockmaking, boats and ships, machinery etc.
Claims (3)
1, a kind of automatic reverse thread tapper is characterized in that comprising housing (13), main shaft (1), mainshaft gear (3), travelling gear (4), auger spindle (6), auger spindle gear (5).
2, by the described automatic reverse thread tapper of claim 1, it is characterized in that also comprising simultaneously on the auger spindle (6) friction (12).
3, by claim 1 or 2 described automatic reverse thread tappers, it is characterized in that also being equipped with simultaneously on the housing (13) backstay (8) and anti-swing arm (10).
