Description

Technical Field

[0001] This utility model relates to the field of CNC vertical grinding machines, and in particular to a cylinder-driven end face measuring instrument specifically for CNC vertical grinding machines. Background Technology

[0002] With the increasing demand for machining irregularly shaped parts (such as triangular, wedge-shaped, and flag-shaped parts) in the new energy industry, traditional horizontal grinding machines, relying on mechanical clamping devices, have exposed significant shortcomings: First, the irregular surface of irregularly shaped workpieces leads to poor clamping stability, making them prone to displacement or vibration during grinding, severely affecting machining accuracy. Second, traditional clamping mechanisms are bulky, restricting the movement path of the grinding wheel and easily causing interference with the workpiece. Third, although existing vertical grinding machines use electromagnetic chucks for clamp-free fixing, their grinding wheel drive mechanism design is redundant, resulting in a high risk of collision between the grinding wheel rod and irregularly shaped workpieces, and the grinding depth adjustment relies on repeated manual adjustments, which is inefficient. In addition, the gas-tight joint at the nose of the electric spindle is prone to interference with surrounding components, and the external cable of the detection device is susceptible to interference, further affecting the reliability and detection accuracy of the equipment. To address these problems, there is an urgent need for a vertical grinding machine device that is compact, flexible in adjustment, and accurate in detection, in order to solve the technical bottleneck of efficient and high-precision grinding of irregularly shaped parts.
