Gradually loosen, at this time pin 5 can gradually squeeze external toothing 3 or between enter in groove 4.
Motor can be started at this time, the depth due to the card of pin 5 such as groove 4 is smaller, and external toothing 3 holds very much at this time
It is easily rotated under the drive of motor and pin 5 is made to be detached from groove 4, keep the dynamics that drill bit 23 rotates insufficient.
Therefore, when needing to increase the dynamics that drill bit 23 rotates, it is only necessary to it is further squeeze shell 1 after, turntable 8 at this time
Will continue to move right, annulus 24 also can further move right, at this time pin 5 can be connected to screw 14 and pin 5 it
Between compression spring 22 under the action of, move down, be further placed in the groove 4 of external toothing 3, at this time 5 clamping external toothing 3 of pin
Put more effort, so that external toothing 3 is not being rotated, while under the action of planetary gear train, planetary gear 6 can rotation and around too
2 revolution of sun wheel, meanwhile, planetary gear 6 can drive turntable 8 to be rotated by connecting rod 7, and then since turntable 8 passes through the first sleeve 9
It connect, therefore drill bit 23 will be rotated at this time, and drills with drill bit 23.
When drilling, since drill bit 23 can be by metope, turntable 8 and drill bit 23 all can be by resistances, simultaneously
Due to the relationship of opposite effect, external toothing 3 and shell 1 can be by reaction forces, simultaneously because being between external toothing 3 and shell 1
It is connected by overloading pin 5, therefore certain overload can be played the role of.
When boring, only keep the pressure of drill bit 23 enough, even if being connected to the rope between sliding block 16 and pin 5
17, in the state loosened, allow pin 5 to be completely disposed in groove 4, the cooperation of external toothing 3 and the holding rather tight of shell 1,
Turntable 8（Relative to planet carrier）It can be rotated, drill bit 23 is made to have enough torques to drill；It similarly it is found that ought not
When needing drilling very firmly, or needing to stop drilling, only need, not in pressing shell 1, to make drill bit 23 and turntable 8 at this time
Under the action of compression spring 22 on being sleeved on connecting rod 7, be moved to the left, can so that pin 5 is detached from or half is detached from external toothing 3,
External toothing 3 can be rotated at this time, so as to reduce the rotation of drill bit 23.
During drill bit 23 and turntable 8 move right, disk 12 can also move right under the action of compression spring 22 at this time
It is dynamic, simultaneously because the setting at the angle of inclination of 13 lower end of bar, after disk 12 touches bar 13 at this time, can squeeze bar 13,
So that the lower end of bar 13 is rotated clockwise, and the spring 20 of the lower end of bar 13 is made to be contacted first with connecting rod 7, at this time due to connecting rod
7 can still rotate under 6 effect of inertia of planetary gear, and the spring 20 of 13 lower end of bar will be encountered when connecting rod 7 rotates at this time, makes connecting rod
7 rotations are reduced, and further, after bar 13 is rotated further, the lower end of bar 13 can stop connecting rod 7 at this time, keep connecting rod 7 complete
It cannot rotate entirely, to make turntable 8 stop operating, external toothing 3 is rotated；Thus, that need not drill, or stop
When use, drill bit 23 can quickly stop, and prevent from accidentally injuring operating personnel.
When being drilled, especially when boring casting beams, reinforcing bar is often encountered, drill bit 23 can quilt at this time
Reinforcing bar snaps into, and to make drill bit 23 rapidly heat up, rotating speed drastically declines, while the reaction force that external toothing 3 is subject to also can be unexpected
Increase, since groove 4 and pin 5 are circle, external toothing 3 can squeeze pin 5, and pin 5 is made to be detached from groove 4, and make outer
Gear ring 3 is rotated, to ensure that shell 1 will not be ensure that shell 1 will not invert and hurt sb.'s feelings by excessive reaction force,
Simultaneously motor overload is also avoided to burn out.
Simultaneously as the inside of pin 5 is fitted with vertical screw 14, while shell 1 is equipped with and coordinates with screw 14
Nut 15, therefore rotating nuts 15, screw 14 can move up and down, by adjusting between 5 inside of 14 bottom of screw and pin
Pressure can adjust the power for the compression spring 22 being connected between screw 14 and pin 5, when so as to according to drilling, reaction force
Size, adjusting appropriate, to meet punching needs.
After punching, shell 1 is not being pressed, turntable 8 is moved to the left at this time, and annulus 24 is moved to the left, and annulus 24 is logical
It crosses driving lever and sliding block 16 and rope 17 pulls pin 5 to move up, so that external toothing 3 is restored rotation, while electricity can also be stopped
Machine rotates, and drill bit 23 is taken out, if be not easy to pull out, can be extracted drill bit 23 by pliers.
The present invention process and principle mainly realized in summary by the interaction of external toothing 3 and turntable 8,
By pressing the degree of drill bit 23, to adjust the stroke that turntable 8 moves left and right, and then the power that pin 5 locks external toothing 3 is adjusted,
To adjust the size for the power that pin 5 overloads, the size of the final power output for realizing control turntable 8；During the work time, when outer
Gear ring 3 once loosens（5 overload of pin acts on）, turntable 8 export power necessarily reduce, this be the present apparatus be protect motor with
And technique effect to be achieved needed for operating personnel.
Drill bit 23 is connected on turntable 8 by the present invention by the way that planetary gear train is arranged, while turntable 8 is similar to row
Carrier realizes the rotation of drill bit 23 so as to the size of the power by adjusting the pressing external toothing 3 of pin 5, slows down and stops,
Moving left and right for turntable 8 is utilized simultaneously, and the compression spring 22 being sleeved on connecting rod 7 effect, realize, and by a left side for turntable 8
It moves right associated with moving up and down for pin 5, realizes only when the pressure of drill bit 23 is enough, can just drill,
The efficiency of punching is improved, simultaneously because the overload effect between pin 5 and groove 4, realizes safety operation, protect simultaneously
The safety of motor and people.
The present invention is by being arranged supporting rod 11, then moving left and right by disk 12, the bar with 11 left end of supporting rod
13 mutual cooperation can make drill bit 23 when need not use, and can quickly stop, and inertia force is passed to outside
Gear ring 3 is prevented when stopping drilling, and drill bit 23 rotates under effect of inertia accidentally injures operating personnel.
The present invention is interrelated by moving left and right for turntable 8 and disk 12 by the way that connecting rod 7 is arranged, and passes through the effect of turntable 8
It moves to control the stalling of external toothing 3, the stalling of turntable 8, while the control of the two is realized by the effect movement of disk 12
It cooperates, that is, the relationship mutually rotated between the external toothing 3 of planetary gear train and planet carrier is taken full advantage of, to realize
The operation of safety.
