Embodiment Construction

[0019] The technical solution of the present invention is further described below, but the scope of protection is not limited to the description.

[0020] A measuring device and testing method for the wall thickness of the bottom of a deep hole part; it includes a base 1 on which a column 4 and two top columns 7 are vertically fixed, and the sliding beam 3 is arranged on the top column 7 On one side of the connection surface, a sliding crossbeam 3 of the base is movably installed on the two top posts 7 and the two top posts 7 are connected by the sliding crossbeam 3. The measuring head of Table 5 is on the same straight line as the center line of the top post 7 .

[0021] A limiting column 2 is also arranged between the two columns 4, and the limiting column 2 is fixedly connected to the base 1 and directly below the sliding beam 3.

[0022] A reference block 6 is also placed on the top column 7 .

[0023] The height of the limit post 2 is greater than that of the top post 7...

Abstract

The invention provides a device and method for measuring wall thickness dimension of a hole bottom of a deep hole part, which comprises a base, wherein an upright post and two top columns are vertically and fixedly connected on the base; sliding cross beams are arranged on one side of a connecting surface of the top column; the two top columns are movably provided with base sliding cross beams andare connected with each other through the sliding cross beams; the sliding cross beams are provided with dial indicators; the measuring head of the dial indicator and the central line of the top column are on the same straight line. According to the device and method for measuring wall thickness dimension of the hole bottom of the deep hole part, the measuring device and the measuring method canbe used for measuring the wall thickness dimension of the hole bottom of the deep hole below IT8 class, and have the advantages of stable measurement data, simple operation and quick measurement. Themeasuring device and the measuring method can be widely applied to measuring the wall thickness of the hole bottom of the deep hole in various ways.

Description

technical field [0001] The invention relates to a measuring device and a testing method for the wall thickness dimension of the bottom of a deep hole part. Background technique [0002] The wall thickness at the bottom of the hole is affected by the diameter and depth of the hole, so there is currently no ready-made measuring tool for direct measurement. like image 3 The conventional method shown is to measure the total length L1 of the part and the depth L2 of the inner hole respectively, and subtract the two to obtain the dimension L of the wall thickness at the bottom of the hole. This method has low measurement efficiency and large measurement errors, and cannot meet the requirements for parts with high precision requirements. There is an urgent need for a measuring device that can ensure measurement accuracy, is simple and quick to operate, and is suitable for field use. Contents of the invention [0003] In order to solve the above technical problems, the present ...
