Description

Technical Field

[0001] The utility model relates to the field of vehicle parts production, in particular to a product inspection tool for a driven wheel of an electric motorcycle. Background Art

[0002] Earlier types of inspection fixtures mainly consisted of manual inspection and some inspection tools. The defects of this method are: the workpiece is large in size and weight, not easy to move, the inner hole is deep, and it is difficult for ordinary inspection tools to achieve accurate inspection dimensions. For the inspection of the inter-tooth profile of gear products, the traditional method is to use three-dimensional inspection equipment for inspection, which requires the use of three-coordinate measuring to mark points on each tooth for measurement. Although the specific value of each tooth can be measured, it takes 15-20 minutes to inspect each product, which is inefficient. Utility Model Content

[0007] Preferably, the sensor is an infrared sensing point.

[0008] Preferably, the width of the detection head is 3 mm greater than the distance between the two gears.

[0009] Preferably, the width of the detection head is 8 mm.

[0010] The utility model designs a driven wheel product inspection tool for electric motorcycles. The driven wheel product inspection tool for electric motorcycles comprises an inspection tool bottom plate. A positioning pin is arranged on one side of the upper surface of the inspection tool bottom plate. The positioning pin is used to complete the positioning of the product. A dial indicator fixing seat is arranged on the other side. The dial indicator fixing seat fixes a detection rod of the dial indicator on the inspection tool bottom plate. One end of the detection rod is connected to a detection head aligned with the product, and the other end is connected to a dial indicator body. The detection head measures the contour between the gears of the driven wheel product. The positioning pin is arranged on the top end of a rotating shaft. The positioning pin is adapted to the center position of the driven wheel product. When the inspection tool is used for inspection, the product is placed in the positioning pin position to complete the positioning. The rotating shaft and the gear center are on the same axial direction. The upper surface of the bottom plate is a reference surface. The detection head of the dial indicator is enlarged and spans across two teeth. The rotating shaft drives the product to rotate. The range of the pointer swing of the dial indicator is the detection feedback of the product contour. The inspection tool mainly measures whether the contour between the gears of the product deviates too much from the processing requirement to judge whether the product is qualified. The worker only needs to observe whether the pointer jump of the percentage tooth exceeds 0.1mm. One product can be inspected in just one minute, which greatly improves the inspection efficiency.
