Single and double blade dual-purpose file fixing device

The invention relates to a single-double-blade double-purpose boring tool fixing device, in particular to a trowel which can be selectively replaced with a single-blade or double-edged blade.

With the advancement of industrial processing technology, the application of automated multi-function processing tools (such as CNC lathes) to process objects such as cutting, drilling, etc., to replace the traditional processing of manpower control tools is becoming more and more popular. The processing type, and the various types of tools and various sizes of tools can be selectively switched to the characteristics of automatic multi-function processing tools in response to various processing operations.

In order to accurately control the size of the hole after drilling, the tool is mainly used for rough milling and finishing milling with a boring tool, and the boring tool is mainly used in the application. The edge boring tool is used for rough milling of the aperture, and then the single-blade boring tool is used for finishing milling. However, since there is no boring fixed structure that can be replaced by single-blade and double-edged cross-blade on the market, the user applies it. During the period, it is necessary to remove the entire set of tools and then replace them. There are troubles in time and labor.

Moreover, in the prior art, in the process of fine milling of the blade boring tool, since the contact point with the cutting object is one side, in the case of unbalanced force, the tool itself may be unstable. Side stress, which is more likely to be caused by the vibration instability of the cutting process. The problem that the cutter is easily collapsed and the like has its inadequacies. Therefore, the inventors of the present invention have thought about and designed a single-double-edged double-purpose boring fixture to improve the defect of the prior art. In order to enhance the implementation and utilization of the industry.
