Description
Technical field
The present invention relates to upright drill or drilling and milling machine, particularly the main speed-changing mechanism of upright drill or drilling and milling machine.
Background technology
The speed of mainshaft gear of upright drill or drilling and milling machine, two big classes are arranged at present: bore diameter is many with pagoda belt pulley speed change less than 30mm's, maximum drilling diameter 30mm is above then uses gear graduation, and this traditional gear shift mode all is to belong to the step speed change transmission.Strap speed varying is very backward mode, but simple because of having, inexpensive, uses extensivelyr on small drilling machine, and big specification drilling machine is then used gear step speed change transmission instead because of belt transmission power finite sum slewing range is less than normal.Gear drive has changed the bel-drivenn deficiency, but shortcoming is also arranged:
1. because of being step speed change, just be difficult in the process select to the optimal speed of mainshaft, normally just lowly do not select the rotating speed level with regard to height, just cause " speed loss " and influence production efficiency and crudy;
2. main speed-changing mechanism structure relative complex.With number of steps of speeds is that 12 grades main speed-changing mechanism is an example, needs 15～18 of gears approximately, 4～5 of power transmission shafts, bearing 8～10 pairs, gear change hand lever assembly 2～3 covers;
3. variable speed operation inconvenience, each speed change all must be stopped earlier and afterwards be pulled handle 2～3 times, if generation " apical tooth " phenomenon also must be operated again, in addition, the direction position of knowing rotating speed label upper handle will be arranged also before variable speed operation.
4. transmission efficiency loss is bigger, and is more because of the transmission middle gear, bearing is more, operational wear power consumption in addition, and transmission efficiency is affected.
5. noise is big.Common 76～the 84Db (A) early of the grating of gears of 12 grades of gears, it all is very difficult wanting to reduce by 2～3Db (A).
Summary of the invention
Task of the present invention is that the variable-frequency stepless speed-regulating technology is introduced in the main speed-changing mechanism of upright drill or drilling and milling machine, for solving the problems of the technologies described above, a kind of drilling machine or drilling and milling machine of the present invention with the frequency control structure, variable-frequency motor handstand is contained in the top of drilling head, the direct plug-in mounting of its shaft extension has on the I axle of gear D, gear C and gear D are housed on the II axle, slippage duplicate gear A and gear B are housed on the III axle, III axle bottom splined shaft then directly transmission give main shaft; On the nut end face iron chains of the upper end of III axle magnet steel is housed, and on magnet steel top sensor to be housed be Hall element, this Hall element is connected with digital display meter; Oil pump is housed in main spindle box spare.
The gear E of the gear F of described oil pump bottom and I axle bottom communicates with I axle, II axle, III axle respectively through separator, oil pipe, and another root oil pipe communicates with fuel injector cup.
Adorn a speed governing knob on the described main spindle box spare, frequency converter is contained in the rear cavity of main spindle box spare and to have the cover cap capping of glass vision panel.
The mini-fan blowing heat radiation of standard is housed on the right wall of described main shaft casing rear cavity.
In concrete application in practice, through technological experiment and cutting examination, the present invention has the following advantages:
1. can select the most economical revolution that reasonably is suitable for accurately for use, not exist in theoretic " speed loss ".
2. mechanism greatly simplifies, and the present invention only needs 5 of gears, 3 of power transmission shafts, bearing 6 pairs, gear change hand lever 1 cover;
3. variable speed operation is convenient, and only need pull handle once just can select a velocity shooting, the speed change of driving then;
4. because of driving member has lacked a lot, transmission efficiency can improve;
5. noise obviously descends, and same specification is compared, and the noise of variable-frequency stepless speed-regulating mechanism is than the decline 5～8dB (A) of gear step speed change mechanism.

The specific embodiment
Referring to Fig. 3, vertical variable-frequency motor 12 stands upside down and is contained in the top of drilling head 17, the direct plug-in mounting of its shaft extension has on the I axle of gear D, gear C 10 and gear D 11 are housed on the II axle 9, slippage duplicate gear A4 and gear B 5 are housed on the III axle 2, III axle 2 bottom splined shafts then directly transmission give main shaft 1.The drive line of representing on Fig. 1 and Fig. 2 is the low speed segment route: by motor through gear D, gear C, gear B, gear A to main shaft, it is motor 20/5320/55 transmission, the speed of mainshaft is 60～397.8r/min, pull handle 3 and make the duplicate gear slippage that makes progress, then become high regime, drive path is: by motor through gear D, gear B to main shaft, its speed of mainshaft is 392.4～2600r/min, it is 60～2600r/min. that the machine spindle speed scopes are formed in the stack of two velocity shootings
In order directly to demonstrate the actual speed of main shaft, on the upper end of III axle 2 nut 7 end face iron chains, 4 magnet steel are arranged, and on magnet steel top sensor 8 to be housed being that Hall element directly demonstrates actual speed with the digital display meter 18 that the main axis rotation magnetic signal is sent to main spindle box spare 17 fronts. speed governing knob 19 is adjusted the output speed of motor in order to the incoming frequency of conversion variable-frequency motor when the driving speed governing.
Referring to Fig. 4, frequency converter 21 is selected for use by the power of motor coupling, be contained in interior and cover cap 20 cappings of rear cavity of main spindle box spare 17 to have glass vision panel. in order to prevent frequency converter long-term work heating, the mini-fan blowing heat radiation of standard is housed on the right wall of main shaft casing 17 rear cavity.
In order to guarantee that gear and bearing have enough lubricated, cooling, oil pump 14 is housed in main spindle box spare, the gear E15 of I axle bottom and the gear F16 of oil pump bottom make oil pump 14 obtain 314～205
3The rotating speed oil transportation of r/min is sent the top of oil to I axle, II axle, III axle respectively through separator, oil pipe etc., and another root oil pipe feeds in the fuel injector cup 6, can clearly observe the working condition of oil pump by fuel injector cup 6.But this oil pump can not be used gear oil pump and plunger displacement pump, and their rotation direction is fuel-displaced, and a noise is big, selects for use the two-way Gerotor pump of SBRB type more suitable.No matter it just changes, reverses can both be fuel-displaced to an oil-out orientation, and noise is low, and the life-span is long, when directed fuel-displaced this point is particularly suitable for drilling machine and drilling and milling machine work, during the main shaft counter-rotating the uninterrupted of driving member lubricated.
