Description

Technical Field

[0001] The utility model relates to the technical field of measuring tools, in particular to a chamfer depth gauge used for measuring a car differential housing. Background Art

[0002] Chamfering refers to the process of cutting the edges and corners of a workpiece into a certain inclined surface. Chamfering is to remove burrs on parts caused by machining and to facilitate part assembly. Chamfers are generally made at the ends of parts. Due to the cutting needs of the workpiece, the angles of the chamfers are also different, so a chamfer gauge is needed to measure the chamfer. Since the existing chamfer gauge is fixed to the chamfer ruler with bolts, it takes a certain amount of time to turn the bolts whether it is fixed or loosened, which is not only very inconvenient, but also easy to cause the chamfer ruler to shake when turning, thereby affecting the accuracy of the chamfer measurement. At the same time, the existing chamfer gauges are divided into two types: digital display and scale. Among them, the digital display chamfer gauge is highly accurate and popular. Since the existing digital display chamfer gauge cannot measure the chamfer when the digital display is damaged, the user also needs to carry a scale chamfer ruler when measuring, which reduces the practicality of the digital display chamfer gauge.

[0003] However, in actual application, dust may fall on the digital display screen and the reading may be inaccurate if it is not cleaned for a long time. At the same time, when measuring deeper, the existing ruler has a limited measuring distance and cannot be used to measure different depths, which makes the measurement more troublesome. Therefore, it is necessary to design a chamfer depth gauge for measuring the car differential housing. Utility Model Content
