Description

Upright drill boring, tapping control apparatus

Technical field

The utility model relates to drilling machine, and particularly a kind of upright drill is used to hole, the control device of tapping.

Background technology

Existing upright drill generally is used for boring, tapping, its operation adopts switch directly to control motor positive and inverse mostly, or employing contactor commonly used, the rotating of relay control motor, the operator must cooperate by both hands simultaneously in operation, before screw tap begins the tapping operation, a hand operated motor control switch, dialling is just changeing a side to motor, and another hand operated main axle moving handle moves down main shaft, this moment the screw tap contact workpiece, the beginning tapping, after the degree of depth that the tapping stroke extremely needs, operating electrical machines gauge tap conversion motor counter-rotating again, make screw tap withdraw from workpiece, because both hands must be handled motor control switch and main axle moving handle simultaneously, therefore very inconvenient to the operator, operating efficiency is low, make mistakes easily, thus operating accidents such as generation fracture of wire awl.

Summary of the invention

Task of the present utility model provides a kind of improved upright drill boring, tapping control apparatus, it has solved low, the problem such as make mistakes easily of prior art inconvenient operation, efficient, and the operator only need manipulate operating grip directly can finish boring, tapping work.

The technical solution of the utility model is as follows:

A kind of upright drill boring, tapping control apparatus, it comprises the drilling machine lathe bed, spindle motor, the main shaft of transmission mechanism and collar bush, the feeding transverse axis, feed worm and feeding worm gear are decided the journey screw rod, operating grip, and electric box, tap holder is housed in the main shaft, screw tap is housed in the tap holder, described feeding transverse axis is the axle that a toothed tooth bar that can drive on the collar bush is realized the axis feeding stroke; In the described electric box control circuit board is housed; The control button that control feeding transverse axis rotates is housed on the described operating grip.

When using the utility model, the operator only need manipulate operating grip directly can finish boring, tapping work.When not carrying out the tapping operation, the operator can place function selector button switch " boring " position, same button (being positioned at the control button that operating grip is not held) promptly is converted to the control button of " auto-feed ", in boring procedure, press control button once more, then " auto-feed " stop, lathe transfers hand feed to.

The utlity model has compact conformation, logic is reliable, power consumption is little, the characteristics of strong interference immunity.

The specific embodiment

Referring to Fig. 1 to Fig. 3, a kind of upright drill of the present utility model has drilling machine lathe bed 1, and its boring, tapping control apparatus comprise spindle motor 2, the main shaft 3 of transmission mechanism and collar bush 4, feeding transverse axis 5, feed worm 6 and feeding worm gear 7, decide journey screw rod 8, operating grip 9, and electric box 10.Tap holder 11 is housed in the main shaft 3, screw tap 12 is housed in the tap holder 11.

Feeding transverse axis 5 is toothed axles, and the tooth bar that it can drive on the collar bush 4 is realized main shaft 3 feed distances.Label 13 is balancing springs.

The control button 91 that control feeding transverse axis 5 rotates is housed on the operating grip 9, and control button 91 inserts electric box 10 by control circuit (as shown in Figure 5).The rotation of feeding transverse axis 5 realizes by operating grip 9 manually, but this moment manipulation operations button 91; Or realize by electromagnetic clutch by feed worm 6 and feeding worm gear 7,

The revolution counter 13 that shows boring, tapping rotating speed is housed on the drilling machine lathe bed 1.

When tapping was operated, screw tap 12 was installed in the tap holder 11, and tap holder 11 usefulness taper shanks are installed in the main shaft 3.In the tapping operating process, because it is pitch feeding by screw tap 12 that main shaft 3 moves, therefore the feed mechanism of lathe part can not mesh, this moment collar bush 4 move up and down the axial tension that produces by screw tap 12 tapping, by the size operation of pitch, when screw tap 12 is attacked certain degree of depth by processing request, can press the button 91 of operating grip 9 ends once more, spindle motor 2 counter-rotating that commutates immediately, screw tap 12 freely withdraws from workpiece, finishes tapping operation thus.

This drilling machine also can adopt the boring limit device of regulating main shaft 3 fronts, promptly decides journey screw rod 8.Prescribe a time limit down to stroke when tapping, limit switch moves, and motor 2 is auto-reverse, and screw tap 12 withdraws from workpiece.

Referring to Fig. 4 and Fig. 5, in the electric box 10 control circuit board is housed, it comprises the electronic logic control element group of being made up of printed substrate and single-chip microcomputer, adopts single-chip microcomputer combination HXPCB3-A type printed substrate to form.As shown in Figure 4, label 101 is the control transformer circuit.As shown in Figure 5, label 102 is the lifting motor circuit; Label 103 is power supply indication circuit; Label 104 is a HXPCB3-A type printed substrate circuit, wherein label 151 is starting switches, the 152nd, shutdown switch, the 153rd, the tapping switch, the 154th, switch is moved back/advances in feeding startup/shutdown switch and tapping, and the 155th, feeding upper limit position switch, the 156th, feeding lower position switch, the 157th, door switch, the 158th, urgent guard's valve; Label 105 is the revolution counter circuit, and wherein label 161 is sensors.

The operator is in carrying out the process of tapping operation with drilling machine, as long as after starting motor and just changeing, direct control operating grip 9 moves down machine tool chief axis 3, allows screw tap 12 contact workpieces, the beginning tapping.After the tapping operation proceeds to the degree of depth that needs, press the control button 91 of operating grip 9 ends, main shaft 3 is changed direction of rotation immediately for counter-rotating, allows screw tap 12 withdraw from workpiece, thereby finishes the tapping operation.After the tapping operation is finished, be converted to drilling operation as need, then selector switch can be placed " boring " position, the control button 91 that this moment, operating grip 9 was not held promptly transfers the control button of " hand feed " and " auto-feed " to.

When using lathe boring, selector switch is gone to " boring " position, lathe can be by boring requirement, select the suitable amount of feeding to carry out drilling operation, the effect of the control button 91 of operating grip 9 ends is to be the auto-feed setting at this moment, when promptly boring needs " auto-feed ", press the control button 91 of operating grip 9 ends.And reach when deciding the journey degree of depth when drilling depth, the action of boring lower position switch, auto-feed stops, and main shaft is back to the upper end initial position automatically.Perhaps when drilling depth reaches a certain position, do not deciding under the state of the journey degree of depth, the control button 91 that operating grip 9 is not held is pressed in boring midway once more, and auto-feed stops, and main shaft returns initial position.
