Moreover, body 10 is provided with a holder 30 passed for rotating shaft 21 upper end above corresponding main shaft 20, this holder 30 be provided with several parallel on the guide rail 31 stretched, and these guide rail 31 tops are jointly across lock one top cover 32, to keep the stationarity of these guide rails 31, moreover these guide rail 31 stage casings are slidably equipped with a stopper connecting plate 33, and stopper connecting plate 33 is provided with a swivel nut 34 passed for rotating shaft 21, swivel nut 34 outside has one section of lock-joining part 340 again, pull for a selective lock of cap 35 that can pass top cover 32, to protect rotating shaft 21, moreover spiral shell is provided with a barrel 36 passed for rotating shaft 21 in swivel nut 34, and rotating shaft 21 is formed with the keyway 210 of upper downward-extension together, and barrel 36 has the keyway 360 of one correspondence, make between barrel 36 and rotating shaft 21, to be equipped with a key block 37, barrel 36 can be rotated in company with rotating shaft 21, and allow rotating shaft 21 can swivel nut 34 upper and lower displacement relatively,
Separately, a use air pressure is provided with in body 10, the cylinder body 40 of oil pressure source, cylinder body 40 has one can be subject to air pressure, the expansion link 41 that oil pressure source action is risen or declined, expansion link 41 has a thread segment 42 again, establish for feed adjusting sleeve 43 spiral shell, and feed adjusting sleeve 43 can utilize a selective location of locknut 44 further, moreover expansion link 41 top has a lock caking 45, this lock caking 45 can coordinate locknut 46 folder to pull on aforementioned stopper connecting plate 33, stretching out of expansion link 41 is made can synchronously to drive stopper connecting plate 33 to move with withdrawal action, the feed again body 10 being separately provided with a corresponding aforementioned feed adjusting sleeve 43 detects element 47, for the stroke by regulating the height of feed adjusting sleeve 43 to change cylinder body 40 expansion link 41,
Whereby, make main shaft 20 can by cylinder body 40 directly movement when forward and back cutter idle stroke, and organize that formation one can move fast, tooth machining unit that low abrasion and being easy to change the outfit assembly.
As for practice of the present invention, then as Fig. 1, shown in Fig. 3 A and Fig. 3 B, operationally, first according to workpiece height, the tapping conditions such as the tapping degree of depth calculate tapping knife and do not contact entering of workpiece, withdrawing idle stroke contacts entering of workpiece with tapping knife, withdrawing impulse stroke, and comply with into, withdrawing idle stroke with enter, withdrawing impulse stroke setting boom 26 resets sensor block 261, withdrawing sensor block 262 and upper limit sensor block 263 respectively corresponding reset detect element 27, withdrawing detects the position that element 28 and the upper limit detect element 29, regulate feed adjusting sleeve 43 height of corresponding expansion link 41 stroke further simultaneously,
Then when starting tapping operation, as shown in Fig. 3 A and Fig. 4 A, now driving element 15 is in static shape, and make cylinder body 40 action expansion link 41 fast retractile, because expansion link 41 utilizes lock caking 45 to lock together with stopper connecting plate 33, therefore the guide rail 31 that stopper connecting plate 33 can be synchronized with holder 30 glides fast, lock due to stopper connecting plate 33 and be provided with swivel nut 34, and together with swivel nut 34 and both barrels 36 are established in spiral shell and barrel 36 and rotating shaft 21 be embedded in by key block 37, therefore can synchronously drive rotating shaft 21 and main shaft 20 to bottom offset, after covering this feed idle stroke, the feed adjusting sleeve 43 on cylinder body 40 expansion link 41 is utilized to arrive when feed detects element 47 [as shown in Figure 4 A], the action of cylinder body 40 expansion link 41 can be stopped, the driving element 15 started on body 10 rotates simultaneously,
Then, as shown in Figure 5A, after driving element 15 is activated, it is by the belt pulley 24 on belt 17 drive shaft 20 rotating shaft 21, because belt pulley 24 is embedded at axle sleeve 22 by key block, and use axle sleeve 22 internal spline engage with the outer tooth bar of rotating shaft 21 and driven, therefore can synchronously drive rotating shaft 21 to rotate, and because rotating shaft 21 being equipped with the barrel 36 established with swivel nut 34 spiral shell, therefore it can drive barrel 36 to rotate relative to swivel nut 34 further, because swivel nut 34 is locked on stopper connecting plate 33, and stopper connecting plate 33 is fixed can not move up and down by cylinder body 40 expansion link 41, therefore it can order about barrel 36 driven rotary axle 21 and advances at a slow speed, for the feed impulse stroke of carrying out tapping,
Afterwards, when tapping completes, then as shown in Figure 5 B, wherein withdrawing detects after element 28 senses withdrawing sensor block 262, makes driving element 15 reverse [as shown in Figure 6A], so can synchronously reverse by action barrel 36, and make barrel 36 driven rotary axle 21 and main shaft 20 increase, allow tapping knife exit workpiece.And further as shown in Figure 6B, when reset detect element 27 detect reset sensor block 261 time, complete withdrawing impulse stroke, namely stop the rotation of driving element 15, start the expansion link 41 of cylinder body 40 to stretch out fast simultaneously, and to be risen rapidly return by stopper connecting plate 33 driven rotary axle 21 and main shaft 20.Finally, as shown in Fig. 3 A and Fig. 3 B, when the upper limit detect element 29 sense upper limit sensor block 263 time, namely stop the action of expansion link 41, and complete the Rapid reset of withdrawing idle stroke;
By above-mentioned structure and action, the present invention can in forward and back cutter idle stroke, driven rotary axle 21 and main shaft 20 advance or return fast can to utilize the expansion link 41 of cylinder body 40 and stopper connecting plate 33, and without the problem that traditional snail wheel and rack contact rubs, and there is effect of movement and low abrasion fast;
Moreover, relatively screw togather and disassembled swivel nut 34, barrel 36 and cap 35 owing to stopper connecting plate 33 more exposing be provided with, therefore in ordinary maintenance maintenance, operating personnel can very easily inspect and perform, and expose and dismantled and assembled design owing to adopting, therefore when there being the demand need changing the assemblies that change the outfit such as swivel nut 34 and barrel 36 in order to coordinate tapping pitch, to be more convenient for effect of dismounting and replacing, the accuracy of processing can be promoted further, and extend its service life, and its surcharge can be improved, and promote its economic benefit.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
In sum, the present invention is in structural design, use practicality and cost benefit, meet completely needed for industry development, and the structure disclosed also is have unprecedented innovative structure, there is novelty, creativeness, practicality, meet the regulation of Invention patent requirement, therefore mention application in accordance with the law.
