The guide sleeve of the main cylinder of the hydraulic machine is a key part in our products. The processing quality of the guide sleeve is a key factor related to whether the sealing performance is good or not, the precision of the sealing groove is important, and the whole workpiece can be scrapped due to the large tolerance range.
The following table shows the dimensions of the sealing groove of the main cylinder guide sleeve of the conventional common machine type:
watch 1
The following measuring tools are now commonly used and have their disadvantages in the measurement:
1) inner groove vernier caliper: the measurement precision is not high, and the accuracy varies from person to person;
2) digital display inner groove vernier caliper: the claw has poor strength and deformation, and the accuracy is different from person to person;
3) connect pole inside micrometer: the measuring rod diameter is too big, receives the restriction of seal groove width, and the suitability is relatively poor, and the dismouting is loaded down with trivial details moreover.
4) Inside diameter scale: the big end can not enter the narrow sealing groove and can not be used.
5) An internal caliper gauge with a meter: the measuring tool is limited by angle errors, the errors are amplified in proportion, the measuring tool is small in measuring range and large in specification, and particularly the size precision grade of a large-specification sealing groove is limited.
Therefore, a tool with high precision, no influence of human factors and large range needs to be realized.
Referring to fig. 1 to 4, an inside diameter dial indicator for measuring a large-depth narrow sealing groove comprises a dial indicator 100, a dial indicator case 200, a case handle 300, a thimble 400, a guide sleeve 500 and a spring 600; the dial gauge case 200 is used for fixing the dial gauge 100; the watch case handle 300 is arranged on the watch case 200; the thimble 400 is arranged on the watch case handle 300 and is positioned on the same axis with the measuring rod of the dial indicator 100; the guide sleeve 500 is sleeved on the thimble 400 and connected with the watch case handle 300; the spring 600 is mounted in the case handle 300 and is fitted over the thimble 400.
