Description

Technical Field

[0001] The utility model belongs to the field of machining detection, and particularly relates to an online measuring tool for hole verticality. Background Art

[0002] In the machining industry, especially in the production of large wheels, flanges and other high-precision parts, the verticality of holes is one of the important indicators for measuring product quality. These parts often have the key functions of transmitting power, bearing weight or precise positioning, so the machining accuracy of holes, especially verticality, is extremely strict. However, in the traditional production and processing process, the detection of hole verticality often becomes a bottleneck restricting production efficiency and product quality improvement.

[0003] At present, the commonly used method for hole verticality detection in the industry is to remove the machined workpiece from the machine tool and move it to a special measuring device for offline detection. Although this method can accurately evaluate the verticality of the hole, it has significant disadvantages:

[0004] 1. Low efficiency: The transfer, clamping and unloading process of workpieces between machine tools and measuring equipment consumes a lot of time and manpower, significantly extending the production cycle.

[0005] 2. Error accumulation: After the workpiece is removed from the machine tool and then re-clamped on the measuring equipment, it is easy to introduce new errors due to slight differences in clamping methods, positions and clamping forces, affecting the accuracy of the measurement results. Especially for large workpieces, the deformation caused by their own weight and the difficulty of clamping are greater, and the error problem is particularly prominent.

[0006] 3. Increased costs: Offline inspection means that if the verticality is found to be not up to standard, the workpiece needs to be returned to the machine tool for secondary processing. This process not only increases the cost of material transfer and secondary clamping, but may also cause surface damage to the workpiece due to multiple clamping, further affecting product quality. Utility Model Content
