Problems solved by technology

Due to the particularity of the gear structure, it cannot be effectively inspected with conventional inspection tools. Although accurate measurement can be achieved by using a three-coordinate measuring instrument, the measurement conditions are high, the measurement time is long, and the measurement cost is high. It is also not suitable for online inspection.

Embodiment Construction

[0015] The present invention will be further described below according to accompanying drawing.

[0016] figure 1 , figure 2 The radial runout detection device of a combined gear tooth of an automobile is shown, which includes three parts: a vertical track structure, a workbench and a measuring mechanism. The vertical track structure is a manual reciprocating straight structure. The skateboard 2 cooperates with a pair of upright rails and moves straight up and down through the handle 3. Pull the handle 3 upward to drive the skateboard 2 to move upward, and move the handle 3 downward to make the skateboard move up and down. 2 moves down, and the down limit position of slide plate 2 is limited by limit post 8. A transverse T-shaped slot for installing the measuring mechanism 4 is left on the front of the slide plate 2 . The workbench is placed flat on the bottom of the track 1 and connected to each other as a whole. The workbench includes a rotor 5, a base 6 and a positionin...

Abstract

The invention discloses a radial runout detecting device of combining gear tooth part of automobile, comprising a vertical rail structure, a workbench and a measuring mechanism. The vertical rail structure is a manual reciprocating straight motion structure, which includes a rail, a sliding plate and a handle. The workbench is installed at bottom part of the rail, which includes a rotor, a base and a location ring; the rotor is vertically installed in the base and can do reciprocating motion relative to the rail plane; the main shaft of the rotor is connected with the location ring which is located with a combining gear to be detected. The measuring mechanism is installed on the sliding plate, which includes a meter rod, a pull spring, a limiting pin, a measuring rod, a locating pin, a measuring head, a tapered wedge, a rod head, a stop rod and a suspension body. The measuring rod is hinged in the suspension body, whose one end is contacted with the meter rod and the other end is axially provided with a measuring head in the combining gear tooth part to be detected. The stop rod and the tapered wedge are cooperated to control the swing of the measuring rod. The invention is suitable for the measuring tool of the production field which has accurate location, convenient measurement and high measuring precision.

Description

technical field [0001] The invention relates to a detection device for radial runout of gear teeth, in particular, the invention relates to a detection device for radial runout of combined gear teeth in an automobile gearbox. Background technique [0002] The coupling gear in the automobile gearbox is a gear with a special structure. Its structural feature is that the coupling teeth are located on the inner end face step or the outer wall next to the external end face step. Because the axial end face and radial distance between the coupling teeth and the step are very small, it cannot Directly use conventional cutting methods to realize tooth forming processing. With the improvement of mold design and manufacturing level, precision forging and compression forming technology has been widely used in this industry to realize combined tooth precision forming processing. In the precision forging production line, it is necessary to detect the radial runout of the teeth in time to ...
