Description

TECHNICAL FIELD

[0001] The utility model relates to turbocharger processing technical field, concretely is a kind of numerical control grinding machine for turbocharger component processing. BACKGROUND

[0002] In the processing flow of the worm gear turbocharger shell, since the shell shape is complex and irregular, when different parts of the shell need to be processed, the shell often needs to be rotated. However, the current workbench design has limitations and cannot achieve flexible rotation of the clamping mechanism. Even if some workbenches are equipped with rotatable clamping mechanisms, these mechanisms often interfere with other parts of the workbench during shell rotation, thereby disrupting the entire processing flow.

[0003] A surface grinder, as an important type of grinder, mainly grinds workpieces through the rotation of a grinding wheel to achieve the required flatness. It can be divided into two categories: rectangular workbench and circular workbench, according to the shape of the workbench. The main parameters of the rectangular workbench include the width and length of the workbench, while the diameter of the circular workbench is the main parameter. In addition, according to the configuration of the shaft, the surface grinder can be further divided into two types: horizontal shaft and vertical shaft.

[0004] However, when using traditional surface grinders to process the parts of the turbocharger, new challenges are encountered. Since the shell of the turbocharger is usually arc-shaped or spiral-shaped, traditional clamps or electromagnetic discs are not powerful enough to fix such shells. This causes the shell to roll easily during polishing, thereby affecting the final quality of the product. To address the above problems, there may be existing technical means to solve them in the prior art, but this case wants to provide an alternative or replacement technical solution.
