Abstract
The utility model relates to an automatic lead screw tapping machine which comprises a servo motor, a spindle, a sleeve and a lower end cover, wherein the servo motor and the sleeve are in butt joint; a nylon connecting sleeve is nested outside a rotor of the servo motor and fixed by a jackscrew; the spindle is mounted at the center of the inside of the sleeve, and a JDB solid lubrication bearing is mounted on the outer side of the spindle; and a copper nut is mounted at the lower end of the sleeve, and a locking nut penetrates through the spindle and is mounted at the lower end of the copper nut. The automatic lead screw tapping machine has the benefits as follows: the structure of the tapping spindle is improved, and a servo driver controls forward and backward rotation of the servo motor; the nylon connecting sleeve is used for driving a lead screw to perform downward tapping feed when the servo motor rotates backwards, and the lead screw performs upwards tapping returning when the servo motor rotates forwards; and compared with other types of tapping machines, the automatic lead screw tapping machine has the advantages of ultra-high-speed tapping and precise tapping, and the tapping efficiency and accuracy are improved effectively.
Description
Technical field
The utility model relates to a kind of automated production equipment, relates in particular to one and leads tooth bar automatic tapping machine.
Background technology
Tapping machine is a kind of lathe with screw tap machining internal thread, is most widely used a kind of internal thread machining lathe.It is light, flexible, efficient and have other similar devices and cannot replace that tapping machine has advantages of, it has avoided the limitation of lathe, drilling machine or hand tapping, and save time, laborsaving, be difficult for not frangibility etc. of rotten tooth, screw tap, be applicable to the industries such as all lathes, mould machinery, plastic machine, printing machinery, package packing machine manufactory, engineering machinery, automobile and motorcycle parts, aero-engine, rolling stock, tobacco machine and universal machine.According to the automaticity difference of tapping machine process, tapping machine can be divided into full-automatic tapping machine, semi-automatic tapping machine and Manual tapping machine, numerical control tapping machine etc.When work, as long as being put into hopper, part blank gets final product automatic feed, location, clamping, tapping, discharging.But existing a lot of same category of device is because the unreasonable production efficiency that causes of tapping main shaft peripheral structure is lower, affect tapping efficiency and precision, structure not rationally, complex operation, need to often safeguard, the various nut thread fineness that process are poor, qualification rate is low.Therefore,, for above aspect, need to carry out rational modification to prior art.
Utility model content
For above defect, the utility model provide a kind of easy easy-to-use, rational in infrastructure, product qualified rate is high, can effectively promote tapping efficiency and precision lead tooth bar automatic tapping machine, to solve many deficiencies of prior art.
For achieving the above object, the utility model is by the following technical solutions:
One is led tooth bar automatic tapping machine, comprise servomotor, main shaft, sleeve, bottom end cover, described servomotor and docking sleeve, this servo motor rotor outer cover has a nylon adapter sleeve and fixes with jackscrew, be positioned at sleeve inner center and pack main shaft into, JDB bearing with solid lubricant is equipped with in described main shaft outside; Sleeve lower end wherein packs copper nut into, and locking nut is contained in copper nut lower end through main shaft, is positioned at sleeve lower end and is provided with bottom end cover.
Correspondingly, pin-and-hole place, described main shaft top loads onto the pin that a length equates with nylon adapter sleeve outside diameter; Described copper nut is by soket head cap screw fixing and locking.
Beneficial effect of leading tooth bar automatic tapping machine described in the utility model is: by improving aspect tapping main axle structure, the rotating of servo-driver control servomotor, in the time that servomotor reverses, lead tooth bar by the drive of nylon adapter sleeve and do tapping feeding downwards, in the time of servomotor forward, leading tooth bar upwards does tapping and returns, there is ultrahigh speed tapping (speed can reach 3000r/min) and accurate tapping compared with the tapping machine of other type, effectively promoted the efficiency and precision of tapping.
Accompanying drawing explanation
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the structural representation of leading tooth bar automatic tapping machine described in the utility model embodiment.
In figure:
1, servomotor; 2, main shaft; 3, nylon adapter sleeve; 4, sleeve; 5, JDB bearing with solid lubricant; 6, copper nut; 7, soket head cap screw; 8, locking nut; 9, bottom end cover.
The specific embodiment
As shown in Figure 1, described in the utility model embodiment, lead tooth bar automatic tapping machine, comprise servomotor 1, main shaft 2, sleeve 4, bottom end cover 9, described servomotor 1 docks with sleeve 4, this servomotor 1 rotor exterior cover has a nylon adapter sleeve 3 and fixes with jackscrew, be positioned at sleeve 4 inside center places and pack main shaft 2 into, JDB bearing with solid lubricant 5 is housed in described main shaft 2 outsides and this main shaft 2 pin-and-hole places, top load onto the pin that a length equates with nylon adapter sleeve outside diameter; Sleeve 4 lower ends wherein pack copper nut 6 into and by soket head cap screw 7 fixing and lockings of M3, locking nut 8 is contained in copper nut 6 lower ends through main shaft 2, is positioned at sleeve 4 lower ends and is provided with bottom end cover 9.When work, 1 rotating of servo-driver control servomotor is driven and is led tooth bar and do tapping feeding downwards by nylon adapter sleeve 3 in the time that servomotor 1 reverses, and leads tooth bar and upwards do tapping and return in the time of servomotor 1 forward.
This case is not limited to above embodiment, and those skilled in the art is according to the announcement of this case, and the improvement of making for this case and modification all should be in the protection domains of this case.
