The present invention adopts the following technical scheme that realization: a kind of two-tube position mechanism improving borehole accuracy, this two-tube position mechanism includes: pedestal;The slide rail being located on pedestal;The slide core being connected on slide rail, one end of this slide core connects pipe position seat, and the other end of this slide core connects buffer gear, and this buffer gear is connected with the piston rod of stroke cylinder, the end of pipe position seat is provided with pipe position portion, and pipe position portion is provided with for boring the brill nozzle hole that nozzle passes.
Wherein, the pipe position portion that is respectively arranged at two ends with of pipe position seat, each pipe position portion end is equipped with for boring the brill nozzle hole that nozzle passes.
Wherein, pipe position seat interlocking is in slide core and by relation in a vertical connection between the first foundary weight and slide core.
Wherein, each pipe position portion is all compressed by second foundary weight and is connected on the seat of pipe position.
Wherein, this two-tube position mechanism also includes the position-limit mechanism connecting slide core.
Wherein, this position-limit mechanism includes the limit base being connected with slide core, the Limit screw that through tailgate and is connected with limit base, is respectively arranged on tailgate two rear flank row limiting section and the limiting section that moves ahead.
Wherein, this buffer gear includes that the buffing pad being fixedly linked with slide core, the fixing buffer spring being located in buffing pad and the buffering being connected buffer spring connect seat, and this buffering connects seat and is connected with the piston rod of stroke cylinder.
Wherein, slide rail is two and parallel is arranged in a mutually vertical manner.
A kind of drilling equipment at least includes a units, and units has brill nozzle, is provided with the described two-tube position mechanism improving borehole accuracy by units.
Wherein, including two units, between two units, the described two-tube position mechanism improving borehole accuracy it is provided with.
Compared with prior art, there is advantages that
Present configuration is simple, two-tube position mechanism is installed additional by the brill nozzle position at drilling equipment, utilize the buffer spring in buffer gear to offset the counteracting force that pipe position portion is produced by processing workpiece when boring, such that it is able to guarantee that pipe position portion is close to process on workpiece without producing deviation, and then improve the degree of accuracy of boring to 0.02mm, high-precision requirement when satisfied such as watch bracelet and five metals class deep drilling.

Detailed description of the invention
The present invention proposes a kind of drilling equipment with two-tube position mechanism, makes brill nozzle operationally will not produce deviation by installing two-tube position mechanism additional in the brill nozzle position of drilling equipment, thus improves the degree of accuracy of boring.
As it is shown in figure 1, drilling equipment at least includes that in a units 1(diagram be three), units 1 has brill nozzle 11, is provided with the two-tube position mechanism 2 for improving borehole accuracy between units 1 side or adjacent two boring units 1.
Shown in Fig. 2 and Fig. 3, two-tube position mechanism 2 specifically includes: pedestal 21;The slide rail 22(slide rail 22 being located on pedestal 21 is the most parallel orthogonal arranges two);The slide core 23 being connected on slide rail 22, one end of this slide core 23 connects pipe position seat 27, the other end of this slide core 23 connects buffer gear 24, this buffer gear 24 includes that the buffing pad 241 being fixedly linked with slide core 23, the fixing buffer spring 242 being located in buffing pad 241 and the buffering being connected buffer spring 242 connect seat 243, this buffering connects seat 243 and is connected with the piston rod of stroke cylinder 25, and the trip cylinder 25 is fixed on the tailgate 211 of pedestal 21;Connecting the position-limit mechanism 26 of slide core 23, this position-limit mechanism 26 includes the limit base 261 being connected with slide core 23, the Limit screw 262 that through tailgate 211 and is connected with limit base 261, be respectively arranged on 211 liang of rear flank row limiting sections 263 of tailgate and the limiting section 264 that moves ahead;Pipe position seat 27 interlocking compresses to ensure relation in a vertical connection between pipe position seat 27 and slide core 3 in slide core 23 and by the first foundary weight 281, and pipe position portion 29 is two in the end of pipe position seat 27 is provided with the 29(this case of pipe position portion, it is arranged on seat 27 two ends, pipe position), pipe position portion 29 is compressed by second foundary weight 282 and is connected on pipe position seat 27, and the end in each pipe position portion 29 is provided with the brill nozzle hole 291 that the brill nozzle 11 for units 1 passes.
The operation principle of above-mentioned two-tube position mechanism 2 is as follows: when needs are holed, the piston rod of stroke cylinder 25 extends through buffer gear 24 and promotes slide core 3 to move forward, slide core 3 drives pipe position seat 27 entirety to travel forward, so that the front end in each pipe position portion 29 withstand need boring processing workpiece, then by units 1 start make brill nozzle 11 bore operation;In boring procedure, the counteracting force in pipe position portion 29 is conducted to slide core 23 by pipe position seat 27, slide core 23 consumes counteracting force when boring nozzle reach to pipe position portion 29 by the buffer spring 242 in buffer gear 24, thus ensures that pipe position portion 29 is close on processing workpiece to be holed;When boring nozzle 11 and being drilled into certain depth without pipe position portion 29, stroke cylinder 25 action makes slide core 23 drive pipe position portion 29 to retreat to rear row limiting section 263 to be resisted against on tailgate 211, spacing and await orders.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent and improvement etc. made within the spirit and principles in the present invention, should be included within the scope of the present invention.
