Problems solved by technology

[0002] At present, the commonly used measuring tool for measuring height with general precision such as mechanical parts is a height gauge. Due to its structure, its measurement accuracy is relatively low, and it can only be used for the measurement of parts with low general precision requirements, while requiring higher precision to measure parts. When the height is high, it is necessary to use high-precision measuring tools such as gauge blocks, dial gauges, and dial gauges for comparison and measurement. These measuring tools are cumbersome and inconvenient to use, and the cost is high, which brings a lot of inconvenience to users.

Abstract

The invention discloses a differential micro-adjustment height gauge, wherein a differential micro-adjustment mechanism is mounted on the ruler body 1 of a ruler, the differential micro-adjustment mechanism comprises a side force constanting device 2, a differential sleeve 3, a fixed internal thread cylinder 4, a micro-motion ruler frame 6, a fixing nut 7 and a differential screw rod 8, wherein the micro-motion ruler frame is mounted on the ruler body 1 through a spring copper sheet and can slide on the ruler body 1, the fixed internal thread cylinder 4 is arranged on the micro-motion ruler frame 6, the differential sleeve 3 is mounted at the upper end of the fixed internal thread cylinder 4, the side force constanting device 2 is mounted at the upper end of the differential screw rod 8 internally arranged inside the fixed internal thread cylinder 4, and the lower end of the differential screw rod 8 is connected with the fixing nut 7. In the invention, the principle of a differential screw pair is used for fine adjustment of dimensional precision, and the differential micro-adjustment height gauge has a simple structure, is convenient to use, and is high in measuring accuracy.

Description

technical field [0001] The invention relates to a height gauge, in particular to a differential fine-tuning height gauge. Background technique [0002] At present, the commonly used measuring tool used to measure the height of mechanical parts and other general precision is the height ruler. Due to its structure, its measurement accuracy is relatively low, and it can only be used for the measurement of parts with low general precision requirements, while requiring higher precision to measure parts. For height, high-precision gauges such as gauge blocks, dial gauges, and dial gauges are required for comparison and measurement. These gauges are cumbersome and inconvenient to use, and the cost is high, which brings a lot of inconvenience to users. Contents of the invention [0003] The purpose of the present invention is to provide a differential fine-tuning height gauge, which uses the principle of differential screw pair to fine-tune the dimensional accuracy, and has a simp...
