Bevel gear forge piece tooth thickness online detection tool

Abstract

The invention provides a bevel gear forge piece tooth thickness online detection tool, and relates to the field of gear machining detection. The bevel gear forge piece tooth thickness online detection tool comprises a bottom plate, the upper surface of the bottom plate is fixedly connected with a base, the upper surface of the base is slidably connected with a supporting rod in a penetrating mode, the top end of the supporting rod is fixedly connected with a rotating shaft, and the outer surface of the top end of the rotating shaft is rotatably connected with a supporting plate in a sleeving mode. A first sliding groove is formed in the upper surface of the supporting plate, and a first threaded rod is rotationally connected into the first sliding groove in a penetrating mode. Through a designed first threaded rod, a designed connecting rod and a designed clamping plate,a bevel gear can be rapidly fixed, a main gear can be fixed without the help of a core shaft, and different bevel gears can be fixed, so the practicability of the detection tool is greatly improved; and through a designed push rod, a push block and a limiting plate, the operation of lifting a dial indicator and rotating the bevel gear at the same time is not needed, and great convenience is brought to operators.

Description

technical field [0001] The invention relates to the field of gear processing and detection, in particular to an online detection tool for bevel gear forging tooth thickness. Background technique [0002] Conical or umbrella-shaped straight bevel gears, commonly known as bevel gears. Bevel gears are used to transmit motion and power between two intersecting shafts. In general machinery, the angle of intersection between the two shafts of bevel gears is equal to 90° (but it may not be equal to 90°). Like cylindrical gears, bevel gears have indexing, tip, root, and base cones. A cone has a large end and a small end, and the circles corresponding to the large end are called the pitch circle (with a radius r), the addendum circle, the dedendum circle, and the base circle. The movement of a pair of bevel gears is equivalent to the pure rolling of a pair of pitch cones. Bevel gears are one of the indispensable and important components in automobile differentials. If there is a p...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a bevel gear forging tooth thickness on-line inspection tool, which solves the problem that the current existing inspection tool is not suitable for large-scale inspection in the production process. The tooth thickness can only be detected after the gear is fixed. Different main gears need to be fixed with mandrels of different sizes, which not only increases the cost of use, but also greatly reduces the practicability of the inspection tool, and the existing bevel gear teeth Thick online inspection tools need to frequently lift the dial indicator and turn the bevel gear when using it, which also increases the workload of the operator
