[specific embodiment]

As shown in the figure, Counterboring head assembly on the perforating press, include can be upper and lower mobile core bar 21 and carry template assembly 40, carry the positioning sleeve 22 that active card is equipped with and can rotates around its center on the template assembly 40, the bottom of positioning sleeve 22 is movably hinged with a plurality of pawls 23 that rise along its circumferencial direction, and the pawl 23 bottom outer walls that rise are the taper surface 231 that is used for reaming.Core bar 21 is inserted in the positioning sleeve 22, fixed installation is useful on the little bearing 221 of location core bar 21 in the positioning sleeve 22, the shaft of core bar 21 is sleeved in the above-mentioned little bearing 221, core bar 21 is provided with pawl 23 upper ends of can roof pressure rising makes its lower end close the tight pawl control piece 20 that rises, and core bar 21 lower ends are provided with and are used for the ejection pawl 23 that respectively rises when mobile and make the protuberance 210 of its opening and closing.Protuberance 210 is a reverse taper among the present invention.

The pawl control piece 20 that rises comprises and is actively set on the outer stage clips of core bar 21 24 and receives pawls cover 25, stage clip 24 and receive pawl cover 25 and all be positioned at pawl 23 tops of rising, and stage clip 24 lower end roof pressures are being received on the pawl cover 25, and stage clip 24 upper ends lean on the set step 211 of core bar 21.Receiving pawl overlaps 25 lower end circumference and is provided with and is used for the rise conical surface 250 of pawl 23 of roof pressure, the pawl 23 upper end correspondences that rise are provided with the inclined-plane 230 that can cooperate with the above-mentioned conical surface 250, overlap under the 25 roof pressure effects at the receipts pawl, open pawl 23 upper ends of rising, and has closed tightly together around the hinge rotation pawl 23 lower ends of rising.

Carrying template assembly 40 includes and puies forward template 41, carry the adapter sleeve 42 that template 41 is provided with upper and lower connection, active card is equipped with the bearing cap 44 that can rotate around its center on the adapter sleeve 42, bearing cap 44 is installed with axle sleeve 43, axle sleeve 43 excircles are provided with driving cog 430, and positioning sleeve 22 is inserted in the above-mentioned axle sleeve 43 and with axle sleeve 43 screw threads for fastening and is connected.

During actual the use, the present invention can be installed on the fixed mount 13 of perforating press, fixed installation is used to locate the bearing holder (housing, cover) 29 of axle sleeve 43 on the fixed mount 13, is installed with lining 292 and a plurality of bearing 291 in the bearing holder (housing, cover) 29, and axle sleeve 43 bottoms are inserted in above-mentioned bearing 291 and the lining 292.Also dress drives the servomotor 31 of positioning sleeve 22 rotations and drives positioning sleeve 22 upper and lower mobile oil cylinders 32 and drive core bar 21 upper and lower mobile oil cylinders 33 on fixed mount 13, servomotor 31 and oil cylinder 33 are fixedly mounted on to be carried on the template 41, oil cylinder 32 is fixedly mounted on the fixed mount 13, puies forward template 41 and links to each other with piston rod on above-mentioned second drive unit 32.

Also can on the piston of oil cylinder 33, connect rotating shaft cover 51, be installed with a last connecting axle 52 that can rotate in the rotating shaft cover 51 around the center, free end and a pair of head nut 53 that should go up connecting axle 52 are fixedly linked, core bar 21 upper ends and double end nut 53 other ends are fixedly linked, like this, thereby core bar 21 can upper and lower moving be controlled pawl 23 opening and closing of respectively rising under the driving of oil cylinder 33, simultaneously core bar 21 since pushing tow in pawl 23 inboards of rising, rotating at a high speed in the reaming process at the pawl 23 of rising can be with pawl 23 rotation of rising, the abrasion of avoid rising pawl 23 and core bar 21 upper convex portion 210.

When the present invention works, oil cylinder 32 drives are put forward template 41, servomotor 31 and oil cylinder 33 integral body and are moved down together, core bar 21, positioning sleeve 22 and the pawl 23 that rises also move down together like this, prepare reaming thereby make on rise pawl 23 and the core bar 21 insertion pipe fittings in the hole to be processed, and oil cylinder 32 suspends subsequently;

Start servomotor 31, travelling gear 310 in servomotor 31 rotating shafts can drive axle sleeve 43, positioning sleeve 22 and pawl 23 quick rotation that rise by driving cog 430 cooperations of synchronous band on axle sleeve 43, starting oil cylinder 33 subsequently drives core bars 21 and moves on slowly, is that outwards open at the center at the core bar 21 lower end protuberances 210 roof pressures pawl 23 that respectively rises with the hinge on it, the reaming processing of the pawl 23 of having realized rising spreading while rotating; Rise simultaneously receipts pawl cover 25 on the pawl 23 upper end roof pressure core bars 21 is received and is moved on the pawl cover 25 and stage clip 24 is further compressed.

Servomotor 31 stops after being worked into preliminary dimension, and oil cylinder 33 drives core bars 21 and moves down and reset and stop, and receives pawl cover 25 and resets under stage clip 24 effects and make the pawl 23 that respectively rises also recover original state; Oil cylinder 32 starts and drives to be carried template 41, servomotor 31 and oil cylinder 33 and moves on the whole to reset and finish reaming.
