Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0013] As shown in the figure, the turning eccentric collet of this embodiment includes a tapered shaft 1 connected to the main shaft of the lathe, the front end of the tapered shaft is provided with a connecting disc 2, and the end surface of the connecting disc is provided with an adjusting disc 3, so The connecting plate is also provided with adjusting screws 4 on both sides in the radial direction to push the adjusting plate to move radially, and the adjusting plate is provided with a bar-shaped groove parallel to the moving direction of the adjusting plate. The plate is fixed on the locking screw 5 on the connection plate;

[0014] A shaft sleeve 6 is also arranged on the adjusting disc, and an elastic collet 7 is arranged inside the shaft sleeve. A nut 8 that moves axially is set.

[0015] In this embodiment, the eccentric collet is used to conn...

Abstract

The invention discloses a tuning eccentric spring collet. The tuning eccentric spring collet comprises a taper shaft, a connecting plate, an adjusting plate and adjusting screws, wherein a shaft sleeve is also arranged on the adjusting plate; an elastic jacket is arranged in the shaft sleeve and is matched with an end part conical surface of the shaft sleeve; and a nut for pushing the elastic jacket to move along the axial direction is arranged on the shaft sleeve. The tuning eccentric spring collet is characterized in that the taper shaft is connected with a lathe spindle; an eccentric shaft is placed in the elastic jacket; an elastic collet is pushed by rotating the nut to move along the axial direction of the shaft sleeve for clamping and fixing the eccentric shaft; locking screws are loosened and the adjusting screws are rotated to push the adjusting plate to move along the axial direction for adjusting an eccentric section of the eccentric shaft to be coaxial with the lathe spindle; the adjusting plate is fixed by the locking screws, and then tuning processing for the eccentric shaft can be performed; the eccentric shaft is fixed by the elastic jacket, and the clamping speed is high; and in addition, a central position of the shaft sleeve is adjustable, so that eccentric shafts with different eccentric distances can be processed, and the university of a clamp is good.

Description

technical field [0001] The invention relates to a fixture, in particular to a fixture for turning an eccentric shaft. Background technique [0002] In the prior art, the structure of the fixture for turning eccentric shafts is relatively complicated, and the clamping speed is relatively slow. The same fixture can only process eccentric shafts with the same eccentricity, and the universality of the fixture is poor. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a turning eccentric collet to solve the problems of slow clamping speed and poor versatility of the fixture for turning eccentric shafts in the prior art. [0004] The eccentric collet chuck of the present invention includes a tapered shaft connected to the main shaft of the lathe, a connecting plate is arranged at the front end of the said tapered shaft, an adjusting plate is arranged on the end surface of the connecting plate, and the connecting plate is arran...
