Description

Technical Field

[0001] The utility model relates to the technical field of casting processing, in particular to an automatic drilling device for machine tool castings. Background Art

[0002] Machine tool castings often need to be punched during processing. Traditional machine tool casting punching needs to be done on a milling machine. At the same time, there are often multiple punching positions, and the positions need to be switched to reposition the punching.

[0003] After searching, it was found that the application number is CN202122661066.3, and the name is an automatic drilling device for castings. The application proposes that the traditional drilling machine fixture can only drill one hole at a time, with low work efficiency and a long time. Through the comprehensive use of the positioning table, rotary lifting cylinder, linear module, gantry, clamping seat and flashlight drill bit, the display support tube workpiece can be quickly positioned, clamped and drilled, and the two electric drill bits can complete two holes on the workpiece at one time. Compared with the previous operation method of only drilling one hole at a time and needing to re-position, the drilling time can be greatly shortened, production efficiency can be improved, and labor intensity can be reduced. At the same time, the accuracy of the drilling position can be guaranteed and the defective rate can be reduced. However, when the application is used, although two holes can be processed at the same time, the drilling operation cannot be performed synchronously when the casting is replaced, resulting in too long waiting time, affecting processing efficiency. Further improvements can be made.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content
