Abstract

The invention discloses a replaceable guide wheel assembly for a sand line cutting device. The replaceable guide wheel assembly for the sand line cutting device comprises a right bearing, a left bearing, a wheel shaft, an inner spacing sleeve, an outer spacing sleeve, a guide wheel hub, a locking washer, a locking nut, a gland and guide wheels. The guide wheel hub is supported on the wheel shaft through the right bearing and the left bearing; conical steps with large ends on the left sides are arranged on the right end of the guide wheel hub; guide wheel inner holes are conical holes with large ends on the left sides, are sleeved on excircles of the steps on the right end of the guide wheel hub, and are fixedly connected onto end faces of the steps on the right side of the guide wheel hub through screws; and a V-shaped guide wire slot is formed in the surface of an outer ring of each guide wheel. The replaceable guide wheel assembly for the sand line cutting device has the further improvement that an included angle alpha 2 at an opening part of the V-shaped guide wire slot in the surface of the outer ring of each guide wheel is larger than an include angle alpha 1 at the bottom of each slot. The replaceable guide wheel assembly for the sand line cutting device provided by the invention is high in guide wheel rotation accuracy, and high in sand line cutting accuracy and convenient to replace sand lines when being used.

Description

technical field [0001] The invention relates to the technical field of sand wire cutting equipment, in particular to a guide wheel assembly. Background technique [0002] The guide wheel assembly includes right bearing, left bearing, wheel shaft, inner spacer, outer spacer, guide wheel hub, lock washer, lock nut, gland and guide wheel, and the guide wheel hub is supported on the bearing. In order to facilitate replacement, a step is provided at the right end of the hub of the guide wheel, and the guide wheel is fitted on the outer circle of the step at the right end of the hub of the guide wheel with clearance fit, and is fixedly connected to the end surface of the step on the right side of the hub of the guide wheel by screws. The main defect of the guide wheel assembly of this structure is that: the guide wheel set is matched with the outer circle of the step at the right end of the guide wheel hub, so that the V-shaped wire groove of the guide wheel may have a relatively ...
