Cylinder liner outer diameter and roundness comprehensive measuring device and using method

Abstract

The invention relates to a comprehensive measuring device for the outer diameter and roundness of a cylinder liner and a method for using it. Six electronic alarm displays from No. 1 to No. 6 are respectively fixed on six contact arms from No. 1 to No. 6, and No. 1 to No. The six contacts are respectively fixed on the six contact arms of No. 1 to No. 6, and the six contacts of No. 1 to No. 6 are arranged inwardly and directly contact with six different key positions on the outer wall of the cylinder liner; the cylinder liner is rotatable. Compared with the prior art, the present invention has the following advantages: electronic display alarms are set in pairs on the same straight line on the same horizontal plane, which can not only detect the changes in the dimensions of the left and right sides of the cylinder liner more sensitively and accurately, but also reflect the The overall roundness and cylindricity of the cylinder liner; the six contact arms are all made inwardly curved arcs to ensure that there is enough space between the contact arms and the measured cylinder liner to prevent interference; the structure is simple and can be adapted to various A working environment, not easy to damage and easy to repair.

Description

technical field [0001] The invention relates to a comprehensive measurement device for the outer diameter and roundness of a cylinder liner and a method for using it. Background technique [0002] In the production of the cylinder liner industry in my country, the measurement of the outer diameter of the cylinder liner is generally carried out with a traditional outer diameter micrometer. This method is inconvenient to operate and has low efficiency. devices, but these devices are complex in structure and costly. [0003] Such as figure 1 As shown, it is a common cylinder liner pneumatic measuring device at present, including the main air pipe 1, the first air pipe 2, the second air pipe 3, the second air hole 4, the first air hole 5, the measuring ring 6, the third air hole 7, the pneumatic buoy indication table 8. When measuring, the device needs to set the measuring ring 6 on the cylinder liner to be tested and move it up and down. Several air holes on the inner ring wa...

AI Technical Summary

Problems solved by technology

Although this equipment has high measurement accuracy, its internal structure is relatively complicated, the cost is high, it is easily damaged and difficult to repair

In addition, this equipment is cumbersome to operate when measuring cylinder liners with different diameters and cylinder liners with steps, and it is necessary to frequently replace measuring rings of different sizes6
