Abstract

The invention discloses a taper shank automatic clamping device. The taper shank automatic clamping device comprises an air cylinder, a push rod, a main shaft, a front cover and a spring clamp sleeve, wherein the air cylinder comprises a cylinder body and an ejection rod, the ejection rod is provided with an axial through hole, the push rod is arranged inside the axial through hole of the ejection rod, the main shaft is a hollow shaft, the ejection rod is arranged inside the main shaft, the head end of the ejection rod is fixedly connected with a locking sleeve, a taper hole is formed in the head end of the locking sleeve, a front cover is arranged at the head end of the main shaft, a taper hole is formed in the inner side face of the front cover, the spring clamp sleeve is arranged inside the main shaft and located between the front cover and the locking sleeve, two end surfaces of the spring clamp sleeve are provided with taper faces respectively matched with the locking sleeve taper hole and the front cover taper hole, a taper hole is formed inside the spring clamp sleeve, and the spring clamp sleeve is provided with a plurality of axial grooves, so that the two ends of the spring clamp sleeve are of a multi-petal structure. The taper shank automatic clamping device can achieve automatic clamping and releasing motions of a taper shank, does not need to carry out fine machining on the taper shank, and is favorable for automatic production.

Description

technical field [0001] The invention relates to an automatic clamping device for a tapered shank. Background technique [0002] When processing a workpiece with a tapered shank, the tapered shank is required to be positioned and clamped before processing the workpiece. Generally, the clamping of the taper shank is fixed and positioned by the friction force of the outer cone surface of the shank, so the outer surface of the taper shank must have a small surface roughness to ensure its clamping force. In the rough machining, the taper surface of the taper shank has not been finished and ground, and its surface accuracy is not enough to have enough friction to clamp the workpiece. At the same time, the error in the direction of the taper diameter causes the axial length of the workpiece. Dimensional changes affect the machining dimensions of the end face of the workpiece. If the grinding process of the shank is carried out first, because heat treatment and other processing ar...
