Dial indicator for depth measurement

Abstract

The invention discloses a dial indicator for depth measurement, and the dial indicator comprises a dial indicator head (1) and a measuring rod (2) which is arranged on the lower end of the dial indicator head (1), and the dial indicator is characterized in that the lower end of the measuring rod (2) is provided with a lengthened measuring head (3), the lower part of the lengthened measuring head (3) is bent to one side to form an elbow (4), the bottom end of the elbow (4) is bent to the same side to form a sharp foot (5), and the bottom surface of the sharp foot (5) is horizontal. Through the lengthened measuring head, the depth measuring range of the dial indicator is enlarged; and on the other hand, the lower part of the lengthened measuring head is designed to a form of the elbow and the sharp foot, so that the dial indicator is easily kept vertical in measurement; and moreover the measuring speed is fast, the measuring precision is high, and the dial indicator is suitable for being popularized to use.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a dial indicator for depth measurement with fast measurement speed and wide range. Background technique [0002] The seat body is one of the main parts of the industrial water pump. There are such circlip grooves in the holes of many machines and equipment, which play a role in preventing the parts on the holes from moving left and right. The design of the circlip groove is marked with tolerances from the groove to the shoulder of the hole. The length of the inner and outer measuring claws of the ordinary vernier caliper is not enough, and it cannot be measured by protruding into the hole. The actual groove width needs to be measured to calculate by using the depth gauge with hook , There is an accumulated error, which makes the depth of the circlip groove of the processed part out of tolerance, resulting in the circlip not being installed or too loose when assembl...

The design of the circlip groove is marked with tolerances from the groove to the shoulder of the hole. The length of the inner and outer measuring claws of the ordinary vernier caliper is not enough, and it cannot be measured by protruding into the hole. The actual groove width needs to be measured to calculate by using the depth gauge with hook , there is an accumulated error, which makes the depth of the circlip groove of the processed part out of tolerance, resulting in that the circlip cannot be installed or is too loose when assembling the circlip, which affects the use function of the part
