Description

TECHNICAL FIELD

[0001] The utility model relates to the field of spare parts detection, and more particularly to an automobile spare parts gauge. BACKGROUND

[0002] In the field of processing and manufacturing of automobile spare parts, the processing procedures of many through holes are often involved in the production process, which are crucial for the subsequent assembly of spare parts. To ensure that the quality of the through holes on the automobile spare parts meets the standards, an effective detection means is essential. When facing mass production, industrial production enterprises need to use efficient tools to control the dimensional accuracy of products, such as hole diameter, spatial size, and other key parameters, which need to be strictly controlled to improve production efficiency and ensure product quality. At this time, the gauge becomes an ideal choice.

[0003] After searching, the Chinese patent with patent announcement number CN216745803U discloses an automobile spare parts gauge, which belongs to the technical field of spare parts gauges. The automobile spare parts gauge includes a limiting long plate, and a second connecting block is rotatably connected to the outer surface of the connecting disc. This automobile spare parts gauge has the effect of preventing the support column from separating from the second connecting block, thanks to the setting of the limiting circular table and the conical groove. The four detection columns form a hole diameter range during use, achieving a wide detection range. The automobile spare parts gauge has the effect of preventing the support long rectangular cylinder from separating from the support long plate, thanks to the setting of the second limiting long rod and the second limiting long groove. The first support ring moves downward during use, achieving high detection accuracy, thanks to the cooperation of the support long plate and the support long rectangular cylinder. However, there are still the following defects:

[0004] (1) In actual use, the detection column needs to be set in the hole first, then the four detection columns are moved until they are supported inside the hole, and finally the size of the hole is measured by the hole diameter range formed by the four detection columns. The whole process is relatively complicated and inefficient.

[0005] (2) In actual use, the second support ring is tightly attached to the surface of the automobile spare part to allow the detection column to vertically enter the through hole on the automobile spare part for measurement. However, when measuring the size of the hole on the curved surface, the curved surface will cause the second support ring to not tightly attach to the surface of the automobile spare part, resulting in the detection column being inclined when entering the through hole, affecting the measurement accuracy. Therefore, an automobile spare parts gauge is proposed. UTILITY MODEL CONTENTS
