Abstract
The invention provides a device for tensioning an auxiliary tool of a milling and boring machine. The auxiliary tool is convenient to replace, high in replacement efficiency and high in precision. The device comprises an auxiliary tool blind rivet and a clamping claw, wherein the tail of the auxiliary tool blind rivet is embedded in an inner cavity when the clamping claw is closed; and the device is characterized in that: the closed clamping claw is positioned in a sleeve; an outer end part of the clamping claw is fastened in a groove on an inner wall of the sleeve in a matched way; a central shaft on a clamping claw base is sleeved in the center of an inner end part of the clamping claw; and the clamping claw base is fixedly connected with a piston rod of a hydraulic cylinder.
Description
Technical field
The present invention relates to the technical field of boring and milling machine structure, be specially the clamping 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 mostly is manual replacing greatly, and it changes the low and low precision of efficient.
Summary of the invention
At the problems referred to above, the invention provides the take-up device of boring and milling machine accessory, it makes that replacing convenience, replacing efficient height, the precision of accessory are good.
The clamping device of boring and milling machine accessory, its technical scheme is such: it comprises accessory blind rivet, claw, the afterbody of described accessory blind rivet is nested in the described claw inner chamber when closed, it is characterized in that: the described claw when closed is positioned at sleeve, the outer end of described claw cooperates the groove that is snapped in described sleeve lining, the inner end center of described claw is equipped with the central shaft of claw base, and described claw base is fastenedly connected the piston rod of hydraulic jack.
It is further characterized in that: described piston rod outer end is set with the disk spring group, the two ends of described disk spring group are mounted on described sleeve bottom face, piston rod base front end face respectively, the outer cover of described piston rod base, disk spring group is equipped with the hydraulic jack cylinder body, the afterbody of described hydraulic jack cylinder body is communicated with oil pipe, and the front end inner edge surface of described hydraulic jack cylinder body is set in the outer edge surface of described sleeve tail end.
After adopting structure of the present invention, accessory is fastenedly connected the front end of accessory blind rivet, during installation, in the inner chamber in the time of only the afterbody of accessory blind rivet need 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, be that claw and sleeve form self-locking structure, and the inner end center of claw is equipped with the claw base, 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 are changed accessory, the hydraulic jack action promotes piston rod, finally make the outer end of claw break away from the groove of sleeve lining, claw outwards moves and opens, make the accessory blind rivet break away from claw, change afterwards; It makes that replacing convenience, replacing efficient height, the precision of accessory are good.
Description of drawings
Fig. 1 is a front view structural representation of the present invention.
The specific embodiment
See Fig. 1, it comprises accessory blind rivet 1, claw 2, in the inner chamber when afterbody of accessory blind rivet 1 is nested in claw 2 closures, 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, claw base 5 is fastenedly connected piston rod 7, 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 respectively, piston rod base 9 front end faces, piston rod base 9, the outer cover of disk spring group 8 is equipped with hydraulic jack cylinder body 10, 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 as follows: accessory is fastenedly connected the front end of accessory blind rivet 1, during installation, in the inner chamber in the time of only the afterbody of accessory blind rivet 1 need 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, claw base 5 is fastenedly connected piston rod 7, 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,, make piston rod base 9 compress dish-shaped groups of springs 8 by oil pipe 11 injection pressure oil in hydraulic jack cylinder body 10, promote piston rod 7, finally make the outer end of claw 2 break away from the groove 4 of sleeve 3 inwalls, claw 2 outwards moves and opens, and makes accessory blind rivet 1 break away from claw 2, changes afterwards.
