Problems solved by technology

For example, installing a center drill on the tool holder will occupy a tool position. When there are many processing tools, there may be no tool positions. This processing method requires time for tool change, and other parts cannot be processed at the same time when drilling. Therefore, the processing efficiency is low, and the processing accuracy is not high, because the center precision of the tool holder is generally 0.01mm

Abstract

The invention relates to a mechanical working device, in particular to a central hole punching device. The central hole punching device is provided with a main shaft assembly comprising a main shaft seat and a central shaft. The central hole punching device is characterized in that the central shaft adopts a tubular structure, and a push rod of which one end is used for installing a center drill is arranged in the tube cavity of the central shaft in a penetrating mode; the push rod is movably matched with the central shaft, and the rear end of the push rod is connected with a piston rod with a push air cylinder; and the push air cylinder is fixedly connected with the main shaft seat. The central hole punching device can punching while a machine tool processes parts, the situation that two sets of mechanisms are adopted in the past is simplified, the cost is reduced, and the operation is convenient. In addition, as the mechanical working device is manufactured on the basis of the existing equipment, the needed cost of improving the existing equipment can be greatly reduced, and production enterprises are beneficial to reform the existing equipment.

Description

technical field [0001] The invention relates to a machining device, in particular to a center hole drilling device. Background technique [0002] In lathe processing, some parts need to drill a center hole for positioning or tightening in the next process. The conventional processing method is to install a center drill on the tool holder, which will have some inevitable shortcomings. For example, installing a center drill on the tool holder will occupy a tool position. When there are many processing tools, there may be no tool positions. This processing method requires time for tool change, and other parts cannot be processed at the same time when drilling. Therefore, the processing efficiency is low, and the processing accuracy is not high, because the center precision of the tool holder is generally 0.01mm. Contents of the invention [0003] The object of the present invention is to disclose a center hole punching device capable of centering a part when the part is proc...
