Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the utility model.
See Fig. 1 to Fig. 3, the resetting chuck of high accuracy punch die of the present utility model, comprising: base 1, elastic chuck 2 and lock nut 3, and three is all preferably rotary structure.Wherein, base 1 is clamped in board, and the head of elastic chuck 2 to be contained in lock nut 3 and can freely to rotate, and after lock nut 3 is connected with base 1, the afterbody of elastic chuck 2 is just contained in the mesopore 4 of base 1; The locating hole 14 for holding workpiece 13 is offered in elastic chuck 2, preferably, the internal diameter 0-0.1mm larger than workpiece 13 external diameter of locating hole 14.
Conveniently locate, prevent concentrated wear simultaneously, the mesopore 4 of base 1 is designed to taper hole 5 in the one end near elastic chuck 2, and precisely, the afterbody of elastic chuck 2 is contained in taper hole 5, correspondingly, the afterbody of elastic chuck 2 is the taper matched with the tapering of taper hole 5, so, weares and teares between whole that is present in conical contact, make this chuck structure have self-sharpening, thus extend the service life of positioning collet.
Conveniently install, base 1 and lock nut 3 are threaded connection, and as shown in Figure 2, base 1 forms protruding external thread part 6 to direction, lock nut 3 place, lock nut 3 is formed with the internal thread 7 coordinated with external thread part 6.In addition, as shown in Figure 3, be also formed in the periphery of lock nut 3 and hook groove 8, positioning collet of the present utility model also comprises a locking wrench 9, for coordinating to be installed tightly by lock nut 3 with hook groove 8, prevents workpiece 13 from occurring to loosen in process.
As an improvement of the present utility model, as shown in Figure 3, the periphery of elastic chuck 2 is formed with a circle locating slot 10, lock nut 3 internal face be then formed match with locating slot 10 one enclose boss 11, can not drop with regard to making the head of elastic chuck 2 be contained in lock nut 3 and can freely rotate like this, also facilitate workpiece 13 automatic capturing center simultaneously, realize Quick-clamped, save the operating time.Given this, conveniently elastic chuck 2 is installed on lock nut 3, the nose shape of elastic chuck 2 is also designed to taper, and locating slot 10 is positioned at the intersection of head taper and end cone.
In order to make collet, there is better toughness, several half grooves 12 equidistantly distributed are formed at the outer peripheral face of elastic chuck 2, so-called half groove 12 refers to the groove that the head of own elasticity dop 2 or afterbody are offered along axis, and groove does not extend to the other end of elastic chuck 2.As a specific embodiment, as shown in Figure 2, the quantity of half groove 12 is 12, and that offers from head and offer from afterbody respectively has 6 and interval setting, so, larger than conventional brace more than 5 times of the clamping range of positioning collet of the present utility model can just be made.
In addition, in order to understand the utility model better, below the processing method of the resetting chuck of this high accuracy punch die being briefly explained, comprising the steps:
S1, select elastic chuck 2 according to workpiece 13 to be processed, the locating hole 14 internal diameter 0-0.1mm larger than workpiece 13 external diameter Φ D of elastic chuck 2;
S2, to be installed in board chuck by base 1 and to clamp and correct, correction accuracy is within 0.003mm;
S3, be contained in lock nut 3 by the head of elastic chuck 2, now elastic chuck 2 can not drop but can freely rotate;
S4, workpiece 13 to be processed is mounted in the locating hole 14 of elastic chuck 2;
S5, lock nut 3 to be fixedly connected with base 1, and with locking wrench 9, both to be locked, process;
The machining accuracy of S6, inspection workpiece 13, repeats step S1-S5.
More than show and describe general principle of the present utility model, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the utility model in any form, the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection domain of the present utility model.
