Problems solved by technology

[0002] At present, in the processing of auto parts, many parts need to process inner grooves, assembly seals and spring clips and other matching grooves, see figure 1 These grooves are all inside the workpiece. It is very difficult to accurately measure the position and size of the inner grooves. Even with a three-coordinate measuring instrument, it is difficult to detect accurately.
Especially for high-end four-wheel drive auto parts, the precision requirements are very high, and the general measurement method is difficult to meet the needs of measuring auto parts

Embodiment Construction

[0020] For an in-depth understanding of internal groove measuring instruments, combine figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 described as follows:

[0021] The inner groove measuring instrument is divided into three parts, the instrument part, the fixed part and the dynamic part. In the inner diameter of the card flap of the chuck head 2, the lock nut 1 is fixed together with the first measuring set 4, the compression spring 3, the elastic contact rod 8 of the instrument, the measuring rod 5, and the second measuring set 6 are linked together, belonging to The dynamic part can measure the size of the groove;

[0022] Measuring technology principle: see figure 1 The product groove structure, the working principle of the inner groove measuring instrument is based on the width and depth of the workpiece product groove, firstly process the positioning cam of the first measuring set 4, and then process the second measuring set 6 mea...

Abstract

The invention relates to a measuring device, in particular to an internal groove measuring device, which belongs to the field of machining measurement, and includes: a dial indicator, a measuring sleeve and a grooved measuring rod, and the dial indicator passes through a lock nut And the measuring gauge card is fixed on the first measuring sleeve, the first measuring sleeve is equipped with a compression spring, and the dial indicator is connected with the elastic instrument contact rod set in the measuring claw; due to the use of the inner groove measuring instrument technology , so that the unmeasurable inner tank value can be measured smoothly, the measurement speed can be increased by more than 10 times, and the measurement accuracy is very accurate.

Description

technical field [0001] The invention relates to a measuring device, in particular to an inner groove measuring device, which belongs to the field of machining measurement. Background technique [0002] At present, in the processing of auto parts, many parts need to process inner grooves, assembly seals and spring clips and other matching grooves, see figure 1 These grooves are all inside the workpiece, and it is very difficult to accurately measure the position and size of the inner grooves, even if a three-coordinate measuring instrument is used, it is difficult to detect accurately. Especially for high-end four-wheel drive auto parts, the precision requirements are very high, and the general measurement method is difficult to meet the needs of measuring auto parts. Contents of the invention [0003] In view of the defects in the prior art, the object of the present invention is to provide a measuring instrument for internal grooves, which adopts the cam principle matche...
