Rear axle gear matching mark photographing system

Abstract

The invention discloses a rear axle gear matching mark photographing system. The rear axle gear matching mark photographing system comprises a base, a driving mechanism, a photographing mechanism and a tightening mechanism, wherein the tightening mechanism comprises a support, a plurality of positioning columns, lead screws, connecting nuts and first connecting rods, wherein gears are placed on the support; the positioning columns are positioned on the support and can slide relative to the support; the lead screws are parallel to the positioning columns; each connecting nut sleeves the corresponding lead screw; each connecting nut is connected with the corresponding positioning column by the corresponding first connecting rod; the positioning columns are abutted to the inner surface of a gear and are jointly matched with one another to fix the gear; the driving mechanism is mounted on the base; an output shaft of the driving mechanism is fixedly connected with the support to drive the support to rotate; and the photographing mechanism comprises an adjusting device which is mounted on the base and can adjust a photographing angle and a camera which is fixed at a head end of the adjusting device. By the rear axle gear matching mark photographing system, the photographing angles of gears in different models can be fixed.

Description

technical field [0001] The invention relates to the technical field of gear quality testing equipment, in particular to a system for photographing rear axle gear pairing impressions. Background technique [0002] The imprint after gear pairing is an important standard for testing the surface quality of gears. After the gears are cut, heat treated, and ground, the paired imprints of the gears must be inspected, and the standard imprints are compared with the actual paired imprints to detect the actual production. Whether the gear meets the requirements of the standard gear, through the reverse adjustment of the gear with unreasonable imprint, control the process parameters of gear cutting, heat treatment, and grinding, so that the matched gear imprint conforms to the standard gear imprint. The accuracy and consistency of the pictures of the print marks after gear pairing directly affects the comparative analysis with the standard gear prints, and further affects the reverse a...

Problems solved by technology

[0003] The current on-site practice is: after the gear cutting, heat treatment, and gear grinding are completed, the inspectors place the gears at will, and take pictures of the gear pairing marks with a hand-held camera. The position of the gears is not fixed every time the photo is taken, and the angle of the camera is also different. This will seriously affect the accuracy and consistency of the photographing of the tooth marks after gear cutting, heat treatment and grinding, affect the comparative analysis with standard gear marks, and further affect the reverse adjustment of the process parameters of gear cutting, heat treatment and grinding
