Abstract
The utility model relates to a drilling machine speed control unit improves, it provides a controlling means who can the section of nothing sets for various rotational speeds, mainly be: if it sets for the ware and constitute to become to be changed by servo motor and torsion, torsion changes gear engagement in the driven gear of drill bit pivot who sets for the ware, and this torsion changes to be set for ware (having another name called the selector) and can increase torsion value, and this servo motor can be and changes various rotational speeds automatically, and consequently, rotation torsion through servo motor, torsion change the pivot section of the nothing variable speed of setting for the ware and can making the drill bit and changes the difference reaches the rotational speed needs that adapt to different apertures and drill.
Description
Technical field
The utility model is that a kind of drilling machine speed control unit improves, and it makes drilling machine automatically can change various speed and torsion without section, and can be easy to use in the boring of different pore size.
Background technology
Through looking into, the drilling machine speed control unit that existing alterable different rotating speeds provides different pore size to hole, substantially all as shown in Figure 1, one board 10 is provided with motor 11, rotating shaft 12, rotating shaft 12 has driven tooth wheels 120 and liftable drill bit 121, motor 11 has driven wheel 110, first paragraph speed changer 13 is provided with between driven wheel 110 and driven tooth wheels 120, second segment speed changer 14, 3rd section of speed changer 15, thus the 121 pairs of object borings of motor 11 interlock drill bit, and can by first, two, three sections of speed changers 13, 14, 15 in conversion three sections of speed, the needs that different pore size is holed are provided, said apparatus, has its own shortcomings in fact: this motor 11 is general single rotary motor, makes drill bit 121 be controlled by first, second and third section of speed changer 13,14,15 in different rotating speeds.And first, second and third section of speed changer 13,14,15 all can only change a kind of rotating speed, in other words, its can only have the change of three kinds of rotating speeds, non-be " without section " speed change, therefore, still have the limitation problem of boring aperture.
Utility model content
Namely the utility model is for improving above-mentioned existing shortcoming, major technique, object are: the motor of drive shaft is set as servo motor, the rotating speed that servo motor self alterable is different, again, be provided with torsion between the driven wheel of this servo motor and the driven tooth wheels of drill bit and change setting apparatus (also known as selector), the torsion that this torsion change setting apparatus alterable is different, therefore, by device of the present utility model, can continuous variable speed be realized and alterable different rotary torsion, and the needs of different pore size and rotating speed boring can be met.
In order to achieve the above object, the utility model provides a kind of drilling machine speed control unit to improve, and be that a board has motor, rotating shaft, this motor has driven wheel, and this board rotating shaft has driven tooth wheels and assembles liftable drill bit; This motor is set as servo motor, this servo motor self can be different rotating speeds, between the driven wheel of this servo motor and the driven tooth wheels of board rotating shaft, be provided with torsion change setting apparatus, this torsion change setting apparatus can make rotating shaft change different rotary torsions, changed the interlock of setting apparatus by servo motor and torsion, drill bit is continuous variable speed and change rotary torsion.
By the utility model, can continuous variable speed be realized and alterable different rotary torsion, and the needs of different pore size and rotating speed boring can be met.

Detailed description of the invention
Refer to Fig. 2, a board 20 has motor, rotating shaft 12, and this motor has driven wheel 210, and the rotating shaft 12 of this board 20 has driven tooth wheels 120 and assembles liftable drill bit 121; Be primarily characterized in that: this motor is set as servo motor 21, this servo motor 21 self can be different rotating speeds, between the driven wheel 210 of this servo motor 21 and the driven tooth wheels 120 of board 20 rotating shaft 12, be provided with torsion change setting apparatus 22, this torsion change setting apparatus 22 is made up of the gear with several different-diameter number of teeth, its can make according to controlling the gear of different-diameter from, close driven tooth wheels 120 in rotating shaft 12, thus make rotating shaft 12 produce the torsion of different size.
According to said apparatus, effect of the present utility model, effect, hereby be described in detail as follows again: referring again to Fig. 2, this servo motor 21 self can be different rotating speeds, therefore, by without section pace of change interlock rotating shaft 12, drill bit 121, again, this torsion change setting apparatus 22 can controlled and on, lower action is the driven tooth wheels 120 of the gear interlock rotating shaft 12 of different-diameter, produce different rotary torsions, thin speech it, when gear wheel in large diameter interlock, in " the slow-speed of revolution, high torsion ", when small diameter gear interlock, in " high rotating speed, low torsion ", by torsion change setting apparatus 22, and can allow the servo motor 21 of continuous variable speed, also large torsion can be produced, high-revolving action, therefore, the boring of different pore size can be provided, when for boring large aperture, need high torsion, the slow-speed of revolution, when for boring small-bore, then variablely turn to low torsion, high rotating speed, separately, also can when holing initial, in high torsion, the slow-speed of revolution, when piercing a bit of degree of depth, then alterable is high rotating speed, low torsion, boring can be completed fast.
From above-mentioned explanation, the utility model can realize continuous variable speed, change different torsion, and can the boring of different pore size easy to use, has splendid practicality and promotes effect, really meeting new patent main idea, earnestly ask gift quasi patent.
