Detailed Description
Referring to fig. 1 to 3, the utility model discloses an utensil is examined in assembly of steering wheel drive unit gear wheel, including bottom plate 1, template 2, locating pin 3 and a plurality of slide axle 4, 4 bottom fixings of slide axle are on bottom plate 1, template 2 is equipped with slide axle 4 matched with slide opening 7 and is used for detecting the inspection hole 6 of gear wheel 5, is equipped with a plurality of and 5 tooth form assorted grooves of gear wheel on the 6 inner walls of this inspection hole, the central axis of locating pin 3 coincides with the central axis of inspection hole 6.
As shown in the figure, the bottom plate 1 and the template 2 are square plates with the same shape, and two sliding shafts 4 are symmetrically arranged on two sides of the center of the bottom plate 1.
The detection principle of the detection tool is as follows: the checking fixture can be matched with a plurality of templates 2, the groove of each template 2 corresponds to a large gear 5 of a certain specification, when the large gear 5 of a certain specification needs to be detected, the corresponding template 2 is selected, the template 2 is fixed on the bottom plate 1 through the matching of the sliding shaft 4 and the sliding hole 7, the positioning pin 3 is positioned at the center of the detection hole 6, then the large gear 5 is taken, the hole in the large gear 5 is firstly sleeved on the positioning pin 3 for positioning to ensure that the central axis of the large gear 5 is coincided with the central axis of the detection hole 6, then the large gear 5 is rotated to enable the teeth to be embedded in the grooves, if the teeth are coincided with the grooves, the large gear 5 is qualified, and if the teeth are not coincided with the grooves, the large gear 5 is unqualified, the detection mode is simple and easy to operate, the structure.
As shown in the figure, a sliding hole II through which a sliding hole I and a sliding hole I are communicated, a mandril 8 positioned in the sliding hole I and a spring 9 for enabling the mandril 8 to retract into the sliding hole I are arranged on the bottom plate, and a sliding rod 10 capable of pushing the mandril 8 out of the sliding hole I is arranged in the sliding hole II; one end of the first sliding hole is provided with a first limiting sleeve 11, the ejector rod 8 is provided with a first limiting ring 12, the first limiting ring is blocked by the first limiting sleeve 11 and cannot be separated from the first sliding hole, the spring 9 is sleeved on the ejector rod 8, and one end of the spring 9 is in contact with the first limiting ring 12; the other end of the spring 9 is in contact with the first limiting sleeve 11; the bottom end of the ejector rod 8 is arc-shaped, and the top end of the sliding rod 10 is conical, so that the sliding rod 10 can jack the ejector rod 8 conveniently.
