Problems solved by technology

However, when using the through boring bar boring method, such as Figure 1 , none of the above-mentioned measuring tools can directly measure the inner hole of the product. In this processing state, in order to reduce the cumbersome operation process of the discharge measurement, the operator usually uses the inner caliper and the outer diameter micrometer for transitional comparison measurement
The operator who performs this measurement method must have a fairly high level of measurement skill
It is difficult for ordinary operators to achieve this level of measurement skills, and the measurement efficiency and accuracy are low

Abstract

The invention belongs to a measuring device for internal holes, in particular to an inside caliper capable of adjusting the measurement range and memorizing the measurement. The memory inside caliper comprises a caliper body, wherein one end of the caliper body is provided with a fixed measuring head, the other end of the caliper body is provided with a movable measuring mechanism, the movable measuring mechanism comprises a loop bar connected with the caliper body, the interior of the loop bar is provided with a slide bar capable of sliding, the end of the slide bar extends out of one end of the loop bar, a tension spring is arranged between the slide bar and the loop bar, the extending end of the slide bar is provided with a movable measuring head, the loop bar is provided with a guide slot, a driving bolt connected with the slide bar is arranged in the guide slot, the other end of the loop bar is provided with a dial indicator, and the moving end of the dial indicator is always attached to the end part of the slide bar. The memory inside caliper is simple in structure and convenient to use, is free from retreating a cutter during measuring, and improves the measuring speed and the processing precision.

Description

technical field [0001] The invention belongs to a measuring device for an inner hole, in particular to an inner caliper capable of adjusting the measuring range and memorizing the measuring size. Background technique [0002] There are many kinds of quantities used in the manufacturing industry for measuring bores, such as bore micrometers, bore gauges, and vernier gauges. However, when using the through boring bar boring method, such as Figure 1 , none of the above-mentioned measuring tools can directly measure the inner hole of the product. In this processing state, in order to reduce the cumbersome operation process of back-off measurement, the operator usually uses the inner caliper and the outer micrometer for transitional comparison measurement. The operator who performs this measurement method must have a fairly high level of measurement skill. It is difficult for general operators to achieve this level of measurement skills, and the measurement efficiency and accur...
