Locating device for machining cross shaft gear of commercial vehicle

Abstract

The invention discloses a locating device for machining a cross shaft gear of a commercial vehicle, and belongs to the technical field of gear machining. The locating device comprises a baseplate, andthe lower surface of the baseplate is connected with a bearing a in a clamping mode; the inside wall of the bearing a is sleeved with a rotating shaft a of which the bottom end is fixedly connected with an output shaft of a driving motor, and the driving motor is fixedly installed on the inside wall of a protective shell; the protective shell is welded on the lower surface of the baseplate; clamping plates are formed by arranging two semicircular connecting pieces in different sizes, and the two clamping plates are staggered; the clamping plates above are driven through threaded columns to move downwards for fixing workpieces in cooperation with the clamping plates below, and the fixing effect is good; an electric push rod is controlled to extend or retract for driving a sliding block toslide in a sliding chute right and left, so that a right U-shaped frame is driven to move right and left; thus, the distance between the two U-shaped frames can be regulated, and the clamping requirements of workpieces in different specifications and lengths are met; and the applicability is wider.

Description

technical field [0001] The invention belongs to the technical field of gear processing, and in particular relates to a positioning device for commercial vehicle cross shaft gear processing. Background technique [0002] A gear is a mechanical element with gears on the rim that continuously mesh to transmit motion and power. The application of gears in transmission has appeared very early. The principle of generative gear cutting method and special machine tools and tools for gear cutting using this principle have appeared one after another. With the development of production, the stability of gear operation has been paid attention to. Generally, there are gear teeth , tooth groove, end face, normal face, addendum circle, dedendum circle, base circle, and indexing circle. The tooth shape of the gear includes tooth profile curve, pressure angle, tooth height and displacement. Involute gears are easier to manufacture. Therefore, among the gears used in modern times, involute g...

Problems solved by technology

[0003] Unstable positioning during the processing of the original cross-axis gear will easily cause the workpiece to shift, and then the processing accuracy of the workpiece will decrease, resulting in an increase in manufacturing and processing costs. At the same time, the workpiece cannot be rotated during the processing process. Unfix and refix, reduce work efficiency
