Abstract
The utility model provides a tensioning device for an auxiliary tool of a boring-milling machine. The tensioning device leads the exchange of the auxiliary tool to be convenient, high in exchange efficiency and good in precision. The tensioning device comprises an auxiliary tool tensioning screw and clamping claws; and the tail part of the auxiliary tool tensioning screw is sleeved in an inner cavity formed when the clamping claws are closed. The tensioning device is characterized in that: the clamping claws are located in a sleeve when the clamping claws are closed; outer end parts of the clamping claws are matched and buckled with grooves on an inner wall of the sleeve; a central shaft of a base of the clamping claws is sleeved at the center of inner end parts of the clamping claws; and the base of the clamping claws is connected with a piston rod of a hydraulic cylinder in a fastening manner.
Description
Technical field
The utility model relates to the technical field of boring and milling machine structure, is specially a kind of take-up device of boring and milling machine accessory head.
Background technology
Boring and milling machine processing in recent years is gradually in automation and high efficiency, and a lot of boring and milling machines all have been equipped with the working ability that various accessory devices enlarge lathe, can realize that as the right angle head is installed on gantry machining center the dish of part side mills Jia Shi and hole processing.But the replacing of existing accessory device is manually to change mostly, and it changes the low and low precision of efficient.
Summary of the invention
To the problems referred to above, the utility model provides a kind of take-up device of boring and milling machine accessory, and it makes the replacing of accessory convenient, replacing efficient is high, precision is good.
A kind of take-up device of boring and milling machine accessory; Its technical scheme is such: it comprises accessory blind rivet, claw; The afterbody of said accessory blind rivet is nested in the said claw inner chamber when closed, and it is characterized in that: the said claw when closed is positioned at sleeve, and the outer end of said claw cooperates the groove that is snapped in said sleeve lining; The inner end center of said claw is equipped with the central shaft of claw base, and said claw base is fastenedly connected the piston rod of hydraulic jack.
It is further characterized in that: said piston rod outer end is set with the disk spring group; The two ends of said disk spring group are mounted on said sleeve bottom face, piston rod base front end face respectively; The outer cover of said piston rod base, disk spring group is equipped with the hydraulic jack cylinder body; The afterbody of said hydraulic jack cylinder body is communicated with oil pipe, and the front end inner edge surface of said hydraulic jack cylinder body is set in the outer edge surface of said sleeve tail end.
After adopting the structure of the utility model, accessory is fastenedly connected the front end of accessory blind rivet, during installation, in the inner chamber in the time of only need the afterbody of accessory blind rivet being nested in the claw closure; Because the claw when closed is positioned at sleeve, the outer end of claw cooperates the groove that is snapped in sleeve lining, and promptly claw and sleeve form self-locking structure; And the inner end center of claw is equipped with the claw base, and the claw base is fastenedly connected the piston rod of hydraulic jack, when processing parts; The pulling force that the accessory blind rivet is received is not enough to overcome the resistance of hydraulic jack, thus accessory blind rivet invariant position, and then make the invariant position of accessory; When needs were changed accessory, the hydraulic jack action promoted piston rod, finally makes the outer end of claw break away from the groove of sleeve lining; Claw outwards moves and opens, and makes the accessory blind rivet break away from claw, changes afterwards; It makes the replacing of accessory convenient, replacing efficient is high, precision is good.
Description of drawings
Fig. 1 is the front view structural representation of the utility model.
The specific embodiment
See Fig. 1; It comprises accessory blind rivet 1, claw 2, and in the inner chamber the when afterbody of accessory blind rivet 1 is nested in claw 2 closures, the claw 2 when closed is positioned at sleeve 3; The outer end of claw 2 cooperates the groove 4 that is snapped in sleeve 3 inwalls; The inner end center of claw 2 is equipped with the central shaft 6 of claw base 5, and claw base 5 is fastenedly connected piston rod 7, and the outer end of piston rod 7 is set with disk spring group 8; The two ends of disk spring group 8 are mounted on sleeve 3 bottom faces, piston rod base 9 front end faces respectively; The outer cover of piston rod base 9, disk spring group 8 is equipped with hydraulic jack cylinder body 10, and the afterbody of hydraulic jack cylinder body 10 is communicated with oil pipe 11, and the front end inner edge surface of hydraulic jack cylinder body 10 is set in the outer edge surface of sleeve 3 tail ends.
Its operation principle is following: accessory is fastenedly connected the front end of accessory blind rivet 1; During installation; In the inner chamber in the time of only need the afterbody of accessory blind rivet 1 being nested in claw 2 closures; Because the claw 2 when closed is positioned at sleeve 3, the outer end of claw 2 cooperates the groove 4 that is snapped in sleeve 3 inwalls, and promptly claw 2 forms self-locking structure with 3 in cover; And the inner end center of claw 2 is equipped with claw base 5, and claw base 5 is fastenedly connected piston rod 7, and the outer end of piston rod 7 is set with disk spring group 8; When processing parts, the pulling force that accessory blind rivet 1 is received is not enough to compress dish-shaped groups of springs 8, so accessory blind rivet 1 invariant position; And then make the invariant position of accessory, when needs unclamp accessory, through oil pipe 11 injection pressure oil in hydraulic jack cylinder body 10; Make and the dish-shaped groups of springs 8 of piston rod base 9 compressions promote piston rod 7, finally make the outer end of claw 2 break away from the groove 4 of sleeve 3 inwalls that claw 2 outwards moves and opens; Make accessory blind rivet 1 break away from claw 2, change afterwards.
