Abstract
The invention discloses an integral chuck for diesel engine processing. The integral chuck is characterized by comprising a rotating shaft, a SMA sleeve, a clamping jaw and a mounting shaft; an axial conical hole is formed in the center position of the right end of the rotating shaft; a large end of the conical hole in the rotating shaft is on the right side; the left end of the mounting shaft is an outer cone; the mounting shaft is mounted in the conical hole of the rotating shaft, and a pull jaw at the left end is locked; the clamping jaw and the rotating shaft are integrated; 3 or 4 cutting grooves are uniformly distributed in the right end of the clamping jaw; the clamping jaw is divided into 3 or 4 parts by the cutting grooves; a cutting groove is formed in an inner hole in the right end of the SMA sleeve; the SMA sleeve is mounted on the outer circular surface of the clamping jaw in an interference manner; and the left end of the SMA sleeve is ejected to a step of the rotating shaft.
Description
Technical field
The present invention relates to diesel engine processing technique field, particularly relate to a kind of diesel engine processing integral type chuck.
Background technology
Developing rapidly and applying along with the microcomputer bed for Micro-cutting Technology, the rotating speed of micro-main shaft and the rotating accuracy of cutter improve constantly, correspondingly very high requirement is proposed to the aspect such as dynamic balance performance and dynamics of cutter clamping device, especially require that there is very high dynamic balance at ultrahigh rotating speed bottom tool clamping device, good centering, such guarantee at a high speed, Ultra-precision Turning, otherwise rotating speed is higher, centrifugal force is larger, when it reaches the critical condition of system, cutter generation exciting will be made, consequently crudy declines, decreased tool life, acceleration main shaft bearing weares and teares, cutter and main shaft can be damaged time serious.And to apply more in micro-main shaft be collet, but its structure or more complicated, and size is less, and dynamic balance is poorer, and its manufacture, alignment error etc. can be delivered on cutter, beating of aggravation cutter.
Summary of the invention
According to above deficiency, the invention provides the diesel engine processing integral type chuck that a kind of cost is low, precision is high and reliable and stable.
For achieving the above object, diesel engine processing integral type chuck of the present invention, main contents are: comprise rotating shaft, SMA sleeve, claw and installation shaft, described rotating shaft right-hand member center is processed with axial bellmouth, bellmouth major part in described rotating shaft on the right, described installation shaft left end is outer cone, described installation shaft is arranged in rotating shaft bellmouth and left end pulling claw is locked, described claw and rotating shaft are integrated, described claw right-hand member is evenly equipped with 3 or 4 groovings, described claw is divided into 3 lobes or 4 lobes by grooving, described SMA sleeve right-hand member endoporus is processed with grooving, the interference of described SMA sleeve is arranged on claw outer round surface, described SMA sleeve left end withstands on rotating shaft step.
As preferably, on described claw, cutting groove depth is 1/2 ~ 2/3 of claw length.
As preferably, on described rotating shaft, the tapering of taper hole is 1:10.
Beneficial effect of the present invention is: structure is simple, and dynamic balance performance is good; Jaw can directly process at axle head, avoids the manufacture because independent chuck part brings, installs equal error; Can also adjust according to the size of application component simultaneously.

Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the invention is described:
Embodiment, see attached Fig. 1 and 2, integral type chuck is used in a kind of diesel engine processing, it is characterized in that, comprise rotating shaft 1, SMA sleeve 2, claw 3 and installation shaft 4, described rotating shaft 1 right-hand member center is processed with axial bellmouth, bellmouth major part in described rotating shaft 1 on the right, described installation shaft 4 left end is outer cone, described installation shaft 4 is arranged in rotating shaft 1 bellmouth and left end pulling claw is locked, described claw 3 is integrated with rotating shaft 1, described claw 3 right-hand member is evenly equipped with 3 or 4 groovings, described claw 3 is divided into 3 lobes or 4 lobes by grooving, described SMA sleeve 2 right-hand member endoporus is processed with grooving, the interference of described SMA sleeve 2 is arranged on claw 3 outer round surface, described SMA sleeve 2 left end withstands on rotating shaft 1 step.
Preferably, on described claw 3, cutting groove depth is 1/2 ~ 2/3 of claw 3 length.
Preferably, on described rotating shaft 1, the tapering of taper hole is 1:10.
By reference to the accompanying drawings the preferred embodiment for the present invention is explained in detail above, but the invention is not restricted to above-mentioned embodiment, in the ken that those of ordinary skill in the art possess, can also make a variety of changes under the prerequisite not departing from present inventive concept.
Do not depart from the spirit and scope of the present invention and can make other changes many and remodeling.Should be appreciated that and the invention is not restricted to specific embodiment, scope of the present invention is defined by the following claims.
