Embodiment Construction

[0012] In the following, the present invention will be further explained based on the drawings and the embodiments.

[0013] figure 1 The bevel gear end face counterbore runout checker shown is composed of bushing 1, mandrel 2, base 3 and dial indicator 4. The base 3 is a flat plate with a through hole perpendicular to the upper plane in the center, and the through hole is used for positioning and installing the mandrel 2. The mandrel 2 is a multi-segment cylindrical shaft with a shoulder in the middle section. The lower section of the shaft is positioned and installed in the through hole of the base 3. The middle shoulder is used for axial limit, leaving an upward facing one. The segment shaft is used to locate and install the bushing 1. The bushing 1 is a thin-walled round bushing, which is positioned and installed on a section of the mandrel 2 facing upwards, and the mating length of the two does not exceed the length of the shaft hole of the bevel gear 5 to be inspected. T...

Abstract

The invention discloses a bouncing detector for an end-surface counter bore of a bevel gear. The detector is composed of a lining, a core shaft, a pedestal and a dial indicator. A downward shaft segment of the core shaft is inserted into a through hole of the pedestal, a middle shoulder is used for axial limiting, and an upward shaft segment is left to positioning and installing the lining. The cooperative length of the lining and the core shaft does not exceed the cooperative shaft-hole length of the bevel gear to be detected. The dial indicator is supported by an indicator frame on the pedestal, a pointer of the dial indicator in a cantilever shape abuts against to the wall of the end-surface counter bore of the bevel gear to be detected, and thus, a measuring structure which rotates, by taking the shaft hole as the reference, to measure the radial bouncing of the end-surface counter bore of the bevel gear to be detected is formed. Measuring reference is consistent with design reference, a measuring result is accurate therefore, the deflection direction of the point of the dial indicator is used to determine the bounding size and direction of a product, convenience is provided for improvements in subsequent processing, and basis is provided for improvement of the product quality.

Description

Technical field [0001] The present invention relates to a check tool for detecting the quality of mechanical parts. Specifically, the present invention relates to a check tool for measuring the runout of a counterbore, especially a bevel gear end face counterbore runout checker. Background technique [0002] Axle gear is a kind of bevel gear, it is the main transmission component of automobile differential, and its design precision and manufacturing precision directly determine the transmission quality. Therefore, in the gear manufacturing process in this industry, in addition to focusing on the quality of the teeth, it must also detect the radial runout of the counterbore of the end face relative to the shaft hole. The radial runout detection of the counterbore on the end face of the bevel gear is a simple measurement. However, there is no universal measuring tool on the market that can be directly used for measurement. In actual production, the mandrel is usually used to locat...
