Abstract

The invention discloses a roller type locating device used for locating and adjustment when a workpiece is clamped. The roller type locating device comprises at least three clamping jaw seats arranged in the peripheral direction of the workpiece, and roller assemblies used for driving the workpiece to rotate when the workpiece is clamped and leveling assemblies used for adjusting the end surface precision of the workpiece are arranged on the clamping jaw seats. According to the roller type locating device, when the workpiece is clamped, the workpiece is driven by the roller assemblies to roll on the chuck clamping jaw seats, so that harmful wear between the workpiece and the locating surfaces of the clamping jaw seats is effectively reduced; besides, the leveling assemblies are used for adjusting the end surface precision of the workpiece and ensuring the leveling precision of the workpiece, and through the cooperation of other clamping jaw seats, realize locating and adjustment when the workpiece is clamped; the roller type locating device is particularly suitable for the radial locating of large thin-walled components and effectively avoids the locating deviation of the large thin-walled components and the damage of wall surfaces, caused by hitting in a locating process; and by the roller type locating device, the whole clamping process is convenient, rapid, accurate and reliable.

Description

technical field [0001] The invention relates to the field of machining, in particular to a roller-type positioning device for machining. Background technique [0002] Chucks have been more and more widely used in the machining industry, and with the continuous improvement of the size and quality of parts to be processed, the difficulty of clamping on the chuck and the adjustment time have also greatly increased. Especially for the processing of batch, heavy workpieces with irregular inner and outer walls, the positioning and clamping process requires constant adjustment and movement of workpieces on the chuck jaws. The existing method is to repeatedly hit the local position of the workpiece with a heavy hammer until the workpiece is aligned. The disadvantage of this method is that the workpiece and the jaws are in surface contact and have sliding friction. As well as the positioning surface of the chuck itself, there are certain frictional damages, especially for some large...
