Efficient tool changing mechanism for numerically controlled lathe

Abstract

The invention relates to the technical field of numerically controlled machine tools, and discloses an efficient tool changing mechanism for a numerically controlled lathe. The mechanism comprises a mounting seat, a driving screw is mounted in the middle of the upper end of the mounting seat, sliding rails are correspondingly arranged at the upper end of the mounting seat and positioned on two sides of the driving screw, sliding seats are slidably arranged at the upper ends of the sliding rails, driving seats are installed on the upper ends of the sliding seats, tool aprons are installed on the upper surfaces of the driving seats, center seats are arranged in the middles of the upper surfaces of the tool aprons, and multiple tools are distributed on the upper surfaces of the tool aprons and located on the outer sides of the center seats in a rectangular shape. Compared with a traditional mode that a tool is fixed through a bolt, the mechanism is faster and more stable, the tool maintaining or detaching time is shortened, the tool replacing efficiency is further improved, meanwhile, the working stability of the tool can be enhanced, the situation that the tool shakes in the workingprocess, and consequently the machining quality of parts is affected is avoided, and the rotating angles of the tool aprons are directly adjusted. Therefore, the tool changing operation of the machinetool can be achieved, and the mechanism is quicker.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tools, in particular to a high-efficiency tool changing mechanism for numerical control lathes. Background technique [0002] CNC machine tool is an automatic machine tool equipped with a program control system. When the CNC machine tool is in operation, during the machining process of the workpiece, after the tool processes a certain number of workpieces, it will wear out, and then continue to process the product, which will reduce the quality of the product. If the requirements are not met, the tool needs to be replaced at this time, and the existing tool changer either adopts a manual tool changer or an automatic tool changer, and the automatic tool changer includes a turret-type tool changer, a belt-disc type Spindle direct tool change device for tool magazine and tool change manipulator tool change device with chain tool magazine. [0003] However, the existing manual tool ...

Problems solved by technology

[0003] However, the existing manual tool change is time-consuming and labor-intensive, which makes the processing efficiency low, while the structure of the automatic tool change mechanism is too complicated, and the tool change process is too cumbersome. At the same time, after the tool change, the stability of the tool needs to be improved. The tool is replaced and repaired, and ensuring the firmness of the tool is a problem we must pay attention to
