Device for measuring distance between positioning shaft shoulder and groove of pipe fitting

Abstract

The invention discloses a device for measuring a distance between a positioning shaft shoulder and a groove of a pipe fitting. The device comprises an outer frame which is composed of an upper frame ring, a lower frame ring and a vertical plate, wherein equal altitude blocks and two first guide rails with upper slide blocks are arranged on the upper frame ring; the upper slide blocks are respectively connected with an output end of a second cylinder; a digital display caliper is arranged under each of the upper slide blocks; the upper end of a ruler section of the digital display caliper is fixedly connected with the lower parts of the upper slide blocks; a first cylinder is arranged on the upper slide blocks; the output end of the first cylinder is downward penetrated through the upper slide blocks and is connected with a measuring slide block on the ruler section of the digital display caliper through a connecting rod; two second guide rails with lower slide blocks are arranged on the lower frame ring; the upper slide blocks are fixedly connected with the corresponding lower slide blocks under the upper slide blocks through the connecting rods. The device can be sleeved on a to-be-processed pipe fitting; on the basis of the measurement of the digital display caliper, the operation is simple; vertical plates in different lengths can be replaced, so that the device can adapt to the pipe fittings in various lengths.

Description

technical field [0001] The invention relates to the technical field of pipe fitting processing, in particular to a device for measuring the distance between a pipe fitting positioning shaft shoulder and a groove. Background technique [0002] Nowadays, when processing pipe fitting grooves, it is necessary to manually measure the distance between the positioning shaft shoulder and the groove to determine the axial feed distance when processing pipe fittings. However, artificial measurement has the defects of inaccurate measurement and limited by the site. For example, it is very difficult to manually measure the distance between the positioning shaft shoulder and the groove in high altitude or areas where it is inconvenient for humans to reach the operation. Even if general machinery is used instead of manual measurement, it is still inconvenient to assemble and disassemble and limited by the working space. When the working space is small, the existing general measuring devi...

However, the artificial measurement has the defects of inaccurate measurement and limited by the site

For example, it is very difficult to manually measure the distance between the positioning shaft shoulder and the groove at high altitude or in areas where it is inconvenient for humans to reach the operation.

Even if ordinary machinery is used instead of manual measurement, it is still inconvenient to assemble and disassemble and limited by the working space. When the working space is small, the existing general measuring devices cannot meet the working requirements.
