The specific embodiment
Below in conjunction with accompanying drawing, the preferred embodiment of the present invention is elaborated.
Refer to Fig. 1, the invention provides a kind of attachment head tensioning device, comprising: ram 9, it longitudinally offers through hole, and the top of ram 9 is provided with the connecting axle 1 that can move up and down; Sleeve 12, its thread bush by lower end 15 is fixedly arranged in the through hole of ram 9; Pull bar 10, it can be arranged in sleeve 12 with moving up and down, and the upper end of pull bar 10 is fixedly connected with connecting axle 1; Pulling claw 14, it is connected to the lower end of pull bar 10, for tension or unclamp accessory head body 18; Piston 6, it is fixedly arranged on the top of pull bar 10 and can moves up and down in sleeve 12; Disk spring 8, it is sheathed on pull bar 10, and its lower end is pushed against on the step of sleeve 12, and its upper end pushes against piston 6; Cylinder cap 5, it is fixedly connected on the upper end of sleeve 12; Signaling switch 3, it is fixed in ram 9 by switch frame 2; The piece 4 of posting a letter, it is fixed on pull bar 10 and is corresponding with described signaling switch 3.
Attachment head tensioning device of the present invention also comprises accessory head body 18, and on accessory head body 18, by blind rivet seat 17 blind rivet 16 that has been threaded, the lateral surface of described blind rivet 16 is provided with the draw-in groove matched with described pulling claw 14.The lower end of pulling claw 14 has hook portion, and pulling claw 14 moves upward and is housed in sleeve 12 when closed, thereby hook portion snaps in tension accessory head in the draw-in groove of blind rivet 16.
Wherein, the piece 4 of posting a letter is for circulus, and it is threaded connection fixed cover and is located on described pull bar 10 and between described connecting axle 1 and described cylinder cap 5.
Signaling switch 3 comprises spaced along the longitudinal direction the first switch 31 and second switch 32.Described pull bar 12 has primary importance and the second place, when primary importance, the described piece 4 of posting a letter is corresponding with described the first switch 31, the pulling claw 14 of described pull bar 10 lower ends is contained in described sleeve 12 and closure, and now pulling claw 14 can be strained the blind rivet of accessory head body 18.When the second place, the described piece 4 of posting a letter is corresponding with described second switch 32, and the pulling claw 14 of described pull bar 10 lower ends stretches out described sleeve 12 expansible downwards to certain angle.
The lower end of pull bar 10 also is fixedly connected with transition axis 13, and described pulling claw 14 is fixedly connected on the bottom of described transition axis 13 by screw thread.Also be provided with adjusting pad between transition axis 13 and described pull bar 10.
Operation principle of the present invention is: in the space between cylinder cap 5 and piston 6 during the injection liquid force feed, promoting piston 6 compression disk springs 8 moves downward, thereby driving pull bar 10 starts to move downward from primary importance, now the pulling claw 14 of pull bar 10 lower ends stretches out sleeve 12 outsides and opens, and the hook portion of pulling claw 14 bottoms snaps in the draw-in groove of blind rivet 16, when pull bar 10 moves to the second place, the piece 4 of posting a letter is corresponding with second switch 32, second switch 32 is sensed the piece 4 of posting a letter, thereby send signal and stop oiling pressure release to fueller, compressed butterfly spring 8 release portion elastic potential energys upwards push away piston 6, thereby driving pull bar 10 starts to move upward from the second place, pulling claw 14 drives blind rivet 16 and enters in sleeve 12, under the restriction of sleeve 12 inwalls, pulling claw 14 closures are by blind rivet 16 and 18 tensions of accessory head body, until pull bar 10 moves to primary importance, the piece 4 of posting a letter is corresponding with the first switch 31, the first switch 31 is sensed the piece 4 of posting a letter, thereby sending signal makes it stop pressure release to fueller, piston 6 stop motions.While changing the accessory head body, only need to repeat said process, pulling claw 14 is first opened and discharge former accessory head body, then capture and strain another accessory head body, very convenient.
Adopt above-mentioned attachment head tensioning device, realized the automatic replacing of accessory head, can laborsavingly also can save time than the manual replacing of accessory head, can realize the automation of lathe.
