Problems solved by technology

[0002] When processing the main shaft of a desktop drilling machine, it is necessary to process an undercut at the end of the inner taper hole of the main shaft. This undercut is mainly used for grinding the subsequent inner taper. If the diameter of the inner taper hole is too small, the front end of the grinding wheel for grinding the inner taper hole may hit the bottom, affecting the machining accuracy of the inner taper hole, and prone to dangerous machining accidents
Since the inner taper hole of the main shaft is relatively slender and the minimum diameter of the small end is small, the size control of the turning undercut can only be controlled by the small tool rest and the tool of the lathe, so the actual size processed is unstable, and because the inner taper hole is smaller The smaller the inner dimension, so the diameter of the undercut cannot be measured with ordinary inspection tools

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings.

[0015] refer to figure 1 , is a checking tool for measuring the diameter of the inner groove of a slender hole, including a caliper 1, a dial indicator 2, an adjustment rod 3 and a spring 4, the caliper 1 is a pincer structure, and is composed of two measuring rods 5 hinged , one of the measuring rods 5 of the calliper 1 is fixedly equipped with a dial gauge 2, and the other measuring rod 5 is fixedly mounted with an adjusting rod 3, and the adjusting rod 3 corresponds to the position of the dial gauge 2, so The length of the adjusting rod 3 relative to the measuring rod 5 can be adjusted, and the measuring ends 6 of the two measuring rods 5 are connected by a spring 4 .

[0016] The adjusting rod 3 and the measuring rod 5 are connected by threads.

[0017] Described spring 4 adopts compression spring.

[0018] When measuring, install the dial indicator 2 on the mea...

Abstract

The invention relates to a gauge used for measuring the inner groove diameter of an elongated hole, which comprises a caliper gauge, a dial indictor, an adjustment lever and a spring, wherein the caliper gauge is of a pincer-shaped structure and formed by hinging two measuring rods, one of the measuring rods of the caliper gauge is fixedly provided with the dial indicator, the other measuring rod is fixedly provided with the adjustment lever, the adjustment lever corresponds to the dial indicator in position, the length of the adjustment lever relative to the measuring rods can be adjusted, and measuring ends of the two measuring rods are connected through the spring. The gauge provided by the invention is simple in structure, convenient to use, convenient for measurement at any time in processing at the production field, can improve the processing quality and reduce the processing rejection rate, and has the characteristics of high detection efficiency and high universality.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a detection tool for measuring the diameter of an undercut in a slender hole. Background technique [0002] When processing the main shaft of a desktop drilling machine, it is necessary to process an undercut at the end of the inner taper hole of the main shaft. If the diameter is too small, the front end of the grinding wheel for grinding the inner taper hole may hit the bottom, affecting the machining accuracy of the inner taper hole, and prone to dangerous machining accidents. Since the inner taper hole of the main shaft is relatively slender and the minimum diameter of the small end is small, the size control of the turning undercut can only be controlled by the small tool rest and the tool of the lathe, so the actual size processed is not stable, and because the inner taper hole is smaller The smaller the inner dimension, the diameter of the undercut cannot be measured wi...
