High-machining-precision integrated type hole drilling tapping tool and manufacturing method thereof

Abstract

The invention relates to a high-machining-precision integrated type hole drilling tapping tool and a manufacturing method thereof, and belongs to the technical field of machining equipment. The high-machining-precision integrated type hole drilling tapping tool is composed of a working part and a handle part; the working part is jointly formed by a drill bit part, a screw tap part and a chip space, the drill bit part is located at the front end of the integrated type hole drilling tapping tool, the screw tap part is located at the middle portion of the integrated type hole drilling tapping tool and is continuously connected with the drill bit part, and the chip space is continuously arranged on the surfaces of the drill bit part and the screw tap part; a tool avoiding groove is formed between the screw tap part and the handle part, the handle part is in a regular straight prismatic shape, and three positioning holes are formed in the side face of a prism of the handle part; and in theusing process, balls in a clamping device act on the interiors of the positioning holes in a positioned manner, the clamping force of the integrated type tool is greatly reduced, the clamping state ismore stable, swing of the integrated type tool in machining is reduced, the positioning accuracy and the machining accuracy can be obviously improved, and the drilling and tapping production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of machining equipment, and relates to a machining tool and a manufacturing method thereof, in particular to an integrated drilling and tapping tool with high machining accuracy and a manufacturing method thereof. Background technique [0002] Drilling and tapping are the most common processing methods in machining. Drills are often used for drilling, reaming or countersinking. For small-sized internal threads, wire dimension is almost the only one. Machining tools. Usually, drilling and tapping are completed as two separate processes, one after the other. After drilling, the drill needs to be removed and then the tap is installed. The clamping is unstable in the middle, and there will be slight displacements in the axial and circumferential directions of the drill bit and the tap, which is easy to cause shaking and jumping of the drill bit and the tap. It is very easy to form accumulated errors in the ins...

Problems solved by technology

[0003] Aiming at the disadvantages of poor machining accuracy and complex process caused by the separation of traditional drilling and tapping processes, the present invention proposes an integrated drilling and tapping tool with high machining accuracy and its manufacturing method, which can greatly increase the number of drill bits and taps in the fixture. Medium clamping force can improve the accuracy of drilling and tapping, and the processing efficiency of drilling and tapping can also be effectively improved
