Embodiment Construction
[0007] The present invention is further illustrated below by way of examples.
[0008] The grinding wheel large-aperture detection device includes two outer rods 3, one inner rod 1, the length L1 of the outer rod 3 is 350 mm, the length L2 of the inner rod 1 is 700 mm, and a length electronic display 4 is installed and fixed at the inner end of the outer rod 3. The end vertical type is equipped with a cylindrical roller 2, and the inner rod 1 is inserted into the outer rod 3 to slide with mechanical clearance and slide to any position and can be locked with a lock nut 5 to form a fixed whole. The detection wheel aperture range is H700mm~ H1400mm. Now take the detection of the size of the grinding wheel aperture H=1000mm as an example, the allowable deviation range of the aperture is 0~+0.44mm. First, center the two outer rods 3, lock them up and down with lock nuts 5, and set the length electronic display 4 to zero; in the second step, loosen the lock nuts 5 on the left outer...

The invention discloses a tool for detecting a large aperture of a grinding wheel. The improvement of the invention lies in that the tool comprises three cemented carbide rods including two outer rods and one inner rod, the length of the two outer rods are identical, and the inner sides of the upper planes, of the outer rods, matching with the inner rod are provided hollow bar with symmetric ribs, the inner ends of the outer rods are provided an electronic length display, cylindrical rollers are vertically installed on the outer ends of the outer rods, the inner rod is a rectangular bar with grooves arranged on the inner rod in up-down symmetric means, and the inner rod inserts in the outer rods and slides in the outer rods in a mechanical clearance fit sliding manner and can be locked into a fixed integral body through locking nut. The tool is reasonable in design, novel in structure, convenient for manufacture and wide in measuring scope and is light and convenient. Two sliding outer rods increase measuring scope. The cylindrical rollers vertically installed on the outer ends of the outer rods ensure convenient measurement, and only rollers have to be replaced without manufacturing entire tool when the cylindrical rollers are worn. The tool is highly economical and practical.
Description
technical field [0001] The invention relates to a testing device for grinding wheels, in particular to a testing tool for testing large-diameter grinding wheels. Background technique [0002] The hole diameter of the grinding wheel is the most important technical index in the overall dimension of the grinding wheel. In the technical requirements of the external dimensions of the grinding wheel, only the diameter deviation of the grinding wheel adopts the mechanical fit tolerance, and the other dimensional deviations are relatively wide. With the rapid development of the mechanical processing industry, more and more large-scale mechanical equipment and its accessories need to be processed with large-size grinding wheels. Nowadays, large-scale bearing grinding wheels with a diameter of 1000mm to 1200mm There are not a few. The existing grinding wheel aperture testing equipment is the grinding smooth limit gauge, which is generally made of iron materials that are not easy to ...
