Abstract
The invention relates to a spring chuck in a machine building industry. The spring chuck comprises a hollow spindle, and a flange and a support, which are sequentially arranged on the front side of the spindle. The spring chuck is characterized in that a chuck seat with a through hole is arranged at the front end of the support; an expansion sleeve with a forward opening is arranged in the through hole; and a pop rivet penetrates through the expansion sleeve, is connected with a tightening lever in a cavity of the spindle, and is provided with a cone part with a large front part and a small rear part. The spring chuck has the characteristics of convenience for use and high machining accuracy.
Description
Technical field
The present invention relates to a kind of collet of machinery manufacturing industry.
Background technology
Collet is fast because moving, the high machined in the modern times of precision particularly is used widely in the processing of finding, and formation industrialization, but the collet of standard all is rear pull type to be clamped, cylindrical that can't processing parts, and be mostly to be threaded change inconvenient.
Summary of the invention
The object of the invention is to: for above prior art, design a kind of utilize the cylindrical swelling can the processing parts cylindrical the quick change collet.
The present invention includes the main shaft of hollow and be installed in successively ring flange and the bearing of main shaft front side, it is characterized in that: the bearing front end is installed the base of the carrier head with through hole, the expansion set of the in-built oriented open front of through hole passes the tie rod that expansion set is positioned at spindle cavity with the Latin of pre-large post-small conical section and connects.
The present invention in use, utilize Latin and with make expansion set expansion and closely cooperate with inner bore of part, thereby processed part is fixed.When renewal part, only need to utilize tie rod to promote forward Latin, expansion set unclamps, and just can easily part be taken off.
For making expansion set to the accurate positioning of part to be processed, improve crudy, the through hole of base of the carrier head is the pre-large post-small taper hole that adapts with expansion set, namely this taper hole plays the accurate positioning action to expansion set.For further making base of the carrier head play positioning action, at least a portion of the outer surface of base of the carrier head is the taper coaxial with its endoporus, and further, the outer surface rear portion of base of the carrier head is taper, and the front portion is the cylindricality coaxial with tapering part and endoporus.
Utilize the present invention to carry out the man-hour that adds of identical parts, only need to operate tie rod, make expansion set swelling or loose, just to realize the replacing of part.And during processing different parts, only need to change the expansion set and the Latin that adapt and get final product.And, adopt the very precision of great achievement degree raising part outer processing of taper hole location among the present invention between expansion set and base of the carrier head.Therefore, the present invention has easy to use, the characteristics that machining accuracy is high.

Wherein, 1, tie rod, 2, main shaft, 3, ring flange, 4, bearing, 5, base of the carrier head, 6, expansion set, 7, Latin.
The specific embodiment
As shown in the figure, the present embodiment comprises tubular spindle 2, and tie rod 1 is housed in the main shaft 2, and the front end of main shaft 2 is equipped with ring flange 3 and bearing 4 successively, at the front end mounting clamp headstock 5 of bearing 4.The endoporus of base of the carrier head 5 is pre-large post-small taper hole, and the outer surface front portion of base of the carrier head 5 is column, and the rear portion is the conical surface, and the each several part of its outer surface is coaxial with its endoporus.Expansion set 6 to open front is installed in the endoporus of base of the carrier head 5, and anterior Latin 7 with cone passes expansion set 6, ring flange 3 is connected with tie rod 1.Cone on the Latin 7 is pre-large post-small shape.
During use, processed part places base of the carrier head 5 and expansion set 6 outsides, and tie rod 1 utilizes the tapering of Latin 7 and expansion set 6 to make the cylindrical of expansion set 6 become large, swelling part to be processed 8 with Latin 7 under the drive of oil cylinder.
