Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiment of the present invention is described in detail.
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, it is fixedly arranged in the through hole of ram 9 by the thread bush 15 of lower end; Pull bar 10, it can be arranged in sleeve 12 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 straining or unclamping 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; Transmit block 4, it to be fixed on pull bar 10 and corresponding with described signaling switch 3.
Attachment head tensioning device of the present invention also comprises accessory head body 18, and accessory head body 18 to be threaded blind rivet 16 by blind rivet seat 17, and 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 when pulling claw 14 moves upward and to be housed in sleeve 12 closed, hook portion to snap in the draw-in groove of blind rivet 16 thus tension accessory head.
Wherein, transmit block 4 for circulus, 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 first switch 31 and second switch 32 along the longitudinal direction.Described pull bar 10 has primary importance and the second place, block 4 is transmitted corresponding with described first switch 31 described in when primary importance, the pulling claw 14 of described pull bar 10 lower end to be contained in described sleeve 12 and closed, and now pulling claw 14 can strain the blind rivet of accessory head body 18.Transmit block 4 described in when the second place corresponding with described second switch 32, the pulling claw 14 of described pull bar 10 lower end stretch out described sleeve 12 downwards and expansible to certain angle.
The lower end of pull bar 10 is also 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 adjusting pad is provided with 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 injection liquid force feed, promotion piston 6 compresses disk spring 8 and moves downward, thus drive pull bar 10 to move downward from primary importance, now the pulling claw 14 of pull bar 10 lower end stretches out sleeve 12 outside and opens, and the hook portion of pulling claw 14 bottom snaps in the draw-in groove of blind rivet 16, when pull bar 10 moves to the second place, transmit block 4 corresponding with second switch 32, second switch 32 senses and transmits block 4, thus send signal and stop oiling pressure release to fueller, by the butterfly spring 8 release portion elastic potential energy compressed, piston 6 is upwards pushed away, thus drive pull bar 10 to move upward from the second place, pulling claw 14 drives blind rivet 16 to enter in sleeve 12, under the restriction of sleeve 12 inwall, pulling claw 14 is closed strains blind rivet 16 and accessory head body 18, until pull bar 10 moves to primary importance, transmit block 4 corresponding with the first switch 31, first switch 31 senses and transmits block 4, thus send signal to fueller make its stop pressure release, piston 6 stop motion.When changing accessory head body, only need repeat said process, make pulling claw 14 first open the former accessory head body of release, then capture and strain another accessory head body, very convenient.
Adopt above-mentioned attachment head tensioning device, achieve the automatic replacing of accessory head, the manual replacing than accessory head can laborsavingly also can save time, and can realize the automation of lathe.
