Problems solved by technology

If you squint from above or from below, the measurement results will be quite different
Second, "fine-tuning until the highest point of the washer is in contact with the upper end of the caliper". This contact can only be determined manually. Different testers will definitely feel different. A little more pressure is considered contact, and a little pressure is also considered contact.
The measurement results obtained will also be quite different

Abstract

The invention discloses a height measuring device of a spring washer elasticity test, comprising a height gauge, a base, a metal bedplate and a control circuit. The height gauge comprises a substrate, a ruler, a vernier and a fine adjusting device and is characterized in that the metal bedplate and the height gauge are arranged on the base, the vernier is arranged right above the metal bedplate, the base is also provided with a contact indicator lamp and / or a buzzer, the control circuit is electrically connected with the metal bedplate, the indicator lamp and / or the buzzer and drives the indicator lamp and / or the buzzer to be powered on and work after the vernier comes into contact with a washer to be measured. The height measuring device is simple and practical and has the advantages of higher testing efficiency, higher testing accuracy and higher result consistency.

Description

technical field [0001] The invention relates to a height measuring device, in particular to a height measuring device for a spring washer elasticity test. Background technique [0002] According to the requirements of the national standard GB / T94.1-2008, spring washers need to be tested for elasticity. That is to say, after the spring washer is continuously loaded 3 times according to the specified test load, measure its free height. [0003] Usually the measurement of free height always keeps the tester's line of sight in line with the position where the spring washer is placed horizontally, such as figure 1 shown. Move the height gauge near the highest point of the spring washer, and then manually fine-tune until the highest point of the washer contacts the upper end of the caliper. Write down the caliper reading as the free height of the spring washer elasticity test. [0004] But this measurement method creates two problems. First, "keep the eye level with the posit...
