a drilling center

Abstract

The invention belongs to the field of design and manufacturing of numerical control machine tools, and particularly relates to a drilling and tapping center. The drilling and tapping center comprises a cross-shaped sliding table arranged on a base and a machine head which is arranged above the cross-shaped sliding table and conducts reciprocating motion in the vertical direction; the machine head comprises a machine case and a cutter disc rotatably arranged on the machine case, multiple cutting main shafts used for clamping cutters are arranged on the peripheral direction of the cutter disc at intervals, each cutting main shaft is rotatably arranged in the radial direction of the cutter disc, and the inner end of each cutting main shaft is provided with a gear; the cutter disc is arranged in a telescopic mode in the axial direction of the cutter disc; the machine case is further provided with a transition gear, and in the process that a first driving unit and a second driving unit drive the cutter disc to rotate, stretch out and draw back, the gears at the inner ends of the cutting main shafts can be made to be alternatively meshed with the transition gear. According to the drilling and tapping center, different types of cutters can be installed on the cutter disc, in the machining process, different cutting main shafts can be switched to be meshed with the transition gear, and different types of machining processes can be implemented; the cutter changing rhythm is stable, a transmission structure is simple, the use cost is lower, and the drilling and tapping center is suitable for application and popularization.

Description

technical field [0001] The invention belongs to the field of design and manufacture of numerical control machine tools, and in particular relates to a drilling and tapping center. Background technique [0002] With the development of science and technology, the manufacturing industry has higher and higher requirements for machining precision. Traditional machining equipment has long been unable to meet the increasingly demanding process requirements. Therefore, CNC machine tools, a highly automated machining process, were born. Equipment, CNC machine tools adopt CNC system to automatically control the cutting, feeding and other actions of the machine tool, which can realize precise control of cutting amount and greatly improve production efficiency. The machining center is a CNC machine tool with a higher degree of automation. It can combine various processes such as milling and drilling, and multi-process cutting and forming at one time. The degree of automation is extremel...

The machining center is a CNC machine tool with a higher degree of automation. It can combine various processes such as milling and drilling, and multi-process cutting and forming at one time. The degree of automation is extremely high. However, this outstanding advantage is also doomed to have great The cost of manufacturing and using the Philippines, the price of a machining center is often as high as millions, and ordinary small and medium-sized enterprises cannot afford such a high cost
