Abstract
The utility model relates to a pipeline accessories tapping apparatus; the tapping head frame is provided with a left, a right, and a middle three tapping heads, wherein, the left and the right tapping heads are parallel, and the middle tapping head is vertical downward between the left and the right tapping heads; the tapping head frame is cast into integration and fixed on a working table surface; a drive motor is used to drag a worm bar and a worm wheel in a speed changing case to carry out speed reduction, so rotary power can be output in the proper cutting rotary speed to drag the tapping head rotate. The tapping apparatus is especially suitable for the thread machining of pipe joints of liquid or gases. The utility model has the advantages of simple structure, low cost, steel saving, high work efficiency, and convenient operation.
Description
The utility model relates to a kind of conduit fittings chasing bar, is to be specifically designed to pipeline to be installed screw thread-like processing equipments such as the various connectors of usefulness and valve body.
In building industry, the conveying equipment of hot-water heating, coal gas, industrial gasses, liquid, and conduit under fluid pressures such as automobile, tractor, hoisting machinery, lathe in the transport service comprise hose coupling, all need the processing of pipe fitting screw thread, the consumption of conduit fittings threading apparatus is very big.Existing chasing bar can not adapt to multiple industry, the processing of the screw thread of multiple product, and original general pipe fitting processing unit (plant), and huge, the complex structure of fuselage, cost height, power consumption be many, use also inconvenience of maintenance.
The purpose of this utility model is to provide a kind of function ratio more complete, simple in structure, and can be widely used in the multi-purpose conduit fittings chasing bar of processing.
The purpose of this utility model is to realize like this.Comprise fuselage, drive motors, gearbox body, the tapping headstock and workpiece clamping mechanism in this chasing bar structure, the feature part is to drag a pair of worm gear in the gearbox by motor, reach deceleration, by the axle I in the worm gear drives gearbox body, by two groups of gears that are connected on two electromagnetic clutch on the axle I and the clutch, axle I, axle II are parallel, realize positive and negative two kinds of transmissions, just change the variation of two kinds of speed and a kind of speed of reversing.The bevel gear of axle II end passes to three bevel pinions simultaneously, by connect gear make left and right, in three tapping-heads rotate synchronously, by pitch feed, the withdrawing of the feeding screw of being mixed.
What accompanying drawing 1 provided is structural representation of the present utility model.
Fig. 2 is transmission principle figure of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described.
With reference to accompanying drawing 1, processed conduit fittings 1 is clipped in the centre of three tapping headstocks 3, the 2nd, threading tool (screw tap) is installed on the tapping headstock 3, left and right, in three tapping headstocks 3 be integral casting forming, be fixedly mounted on the work top of fuselage 9 upper left-hand, guarantee the axiality and the perpendicularity of processed annex, and increased the rigidity and the intensity of chasing bar.Electric appliance box 4 is in the right back of back, gearbox body 6 is located at the right front of back, and gear shift fork handle 5 is arranged above, rotates shift fork handle 5, can make the gear 14 and 15 in the gearbox body throw off (see figure 2)s, transfer gear 16 to and 17 engagements become the (see figure 2) that slowly runs.The deceleration of complete machine, speed change are by the electromagnetic clutch in the gearbox body and three groups of travelling gears and the realization of a pair of worm gear.The 7th, oil ga(u)ge can be observed the need oil situation in the gearbox thus, and the 8th, drive motors, be positioned at underbelly, the 10th, discharging opening is positioned at fuselage left side, workbench bottom, product after the processing, tapping is finished, and freely falls by discharging opening 10 after clamp mechanism is unclamped to skid off.As shown in Figure 2, motor 8 is dragged the belt pulley 11 of gearbox by 4 V-belts, drive a pair of worm gear 12 and 13 in the gearbox body 6, change the power input direction and driven the rotation of axle I, when electromagnetic clutch 27 energisings, gear 14 and spline gear 15 engagements, driving the axle II rotates, make a bevel gear of II end 21 and a left side, in, right three bevel pinions, 22 engagements, drive 23 simultaneously, 24 3 covers connect gear, make three tapping headstock rotation tapping, the feeding of tapping axle is according to feed screw, the thread pitch of screw 29 carries out, and leading screw, screw 29 is complementary according to the needed pitch of processing work.When the shift fork handle 5 that rotates gearbox, at this moment the gear 14 of spline gear 15 and axle I is thrown off, gear 16 engagements of gear 17 and axle I at this moment, and by above-mentioned driving-chain, the axle II can obtain a lower rotating speed, has adapted to larger-diameter processing work.When electromagnetic clutch 27 outage, electromagnetic clutch 28 instantaneous energisings can be stopped the rotatory inertia of gear.Electromagnetic clutch 26 energisings, electromagnetism is from device 28 outages, electromagnetic clutch 26 driven gears 18 drag an II by gear 19,20, at this moment gear 14,16 idle running that feeding is just being changeed, make bevel gear 21 counter-rotating, simultaneously around three bevel pinions 22 and connect gear 23,24 make left and right, in three tapping headstocks 3 along the screw thread of leading screw screw with cutter 25 by withdrawing from the workpiece.When it should be noted that 26,27 two electromagnetic clutch no powers, clutch 28 energisings are braking actions, clutch 26,27 any one clutch energising, and clutch 28 all cuts off the power supply.
The feeding of the utility model chasing bar---returning is by the control of the auxiliary reclay in the electric appliance box.Control button then is the integrated circuit low-voltage control signal, and is safe and reliable, its control program for manually-feeding-return uses when adjusting cutter.Automatically-and feeding-return, two programs are arranged, one is single cycle, promptly finishes above-mentioned action and promptly stops automatically; Second program is circulation continuously, the program feeding during operate as normal-return back and forth continuously.
The utility model compared with prior art, have following advantage: one, volume is little, can take less the workshop area; Two, in light weight, conveniently moving is saved steel; Three, noise is low; Four, simple in structure, gearbox only obtains three kinds of speed with I, two main shafts of II; Five, using electricity wisely is than older models economize on electricity 25%; Six, low cost of manufacture, price can be lower than 30% of older models; Seven, standardization level height is convenient to maintenance; Eight, highly versatile, it is universal that the plumbing pipe annex uses cutter, jig, uses the utility model need not order special use Tool mounting; Nine, can according to different industries, change jig and can carry out tapping processing to different workpieces such as high-pressure oil pipe joint, valve bodies.
Pipeline accessories tapping apparatus of the present utility model is applicable to the tapping processing of the various conduit fittings that diameter 50mm is following.
