Embodiment Construction
[0012] The present invention will be described in detail below in conjunction with the accompanying drawings. Such as Figure 1-3 As shown, the round-shaft quick-change chuck of the present invention includes a sleeve 1, three holes 2 are evenly arranged on the upper circumference of the sleeve wall, and round-headed rollers 3 are arranged in the holes, and the round-headed rollers cannot Falling out from the bottom of the hole groove, it also includes an eccentric sleeve 4 that covers three round-headed rollers. The outer wall section of the eccentric sleeve is a regular hexagon. The arc-shaped grooves are respectively used to clamp the corresponding round-headed rollers. End caps 6 are arranged on both sides of the eccentric sleeve. The end caps are connected to the eccentric sleeve through locking screws 7. The end cap and the sleeve are connected by retaining rings. 8 to achieve axial positioning, the retaining ring is clamped with the sleeve, and the end cover is fixedly...

The invention discloses a round-shaft quick-change chuck, which comprises a sleeve. Three holes are uniformly arranged on the wall of the sleeve in the circumferential direction. Round-headed rollers are arranged in the holes, and the round-headed rollers cannot pass through the holes. It also includes an eccentric sleeve covering the three round-headed rollers. The inner wall of the eccentric sleeve is evenly provided with three arc-shaped grooves in the circumferential direction, and the three arc-shaped grooves are respectively used to clamp the corresponding round-headed rollers. , Both sides of the eccentric sleeve are provided with end caps, the end caps are connected with the eccentric sleeve through locking screws, and the axial positioning is realized between the end cap and the sleeve through a retaining ring. The circular shaft quick-change chuck with this structure can conveniently and quickly realize the clamping and replacement of the circular shaft, thereby effectively improving the processing efficiency.
Description
technical field [0001] The invention relates to a round shaft quick-change chuck. Background technique [0002] In the field of batch processing of round shaft parts, it is necessary to quickly clamp and replace round shafts to ensure processing efficiency. In the existing circular shaft fixing structure, the process of clamping and replacing the circular shaft is complicated, the operation is inconvenient, and the processing efficiency is seriously affected. Contents of the invention [0003] In view of this, the object of the present invention is to provide a round shaft quick-change chuck, which can conveniently and quickly realize the clamping and replacement of the round shaft, so as to improve the processing efficiency. [0004] The present invention solves the above problems through the following technical means: a round shaft quick-change chuck, including a sleeve, three holes are evenly arranged on the wall of the sleeve in the circumferential direction, and roun...
