Cutter structure

Abstract

The invention relates to a cutter structure which comprises a cutter main body. A milling cutter portion is arranged on the cutter main body, a chamfering portion is formed on the peripheral edge at the front end of the milling cutter portion, and a thread cutter portion is formed on the cutter main body and located behind the milling cutter portion in a connected mode. Therefore, the chamfering portion in the front of the cutter main body is utilized for achieving an equidistant chamfering function through numerical control, then a numerically-controlled spiral curve equation is utilized for driving a cutter edge of the milling cutter portion to mill a bottom hole, and lastly, the thread cutting portion is used for carrying out a thread milling process continuously, so that forming operation of a threaded hole can be finished once. During implementation, working hours consumed for changing cutters cumbersomely in a machining process can be effectively reduced, errors generated due to recalibration when the cutters are changed for multiple times can be prevented, the cost burden for purchasing the multiple cutters and machine tools can be further avoided, and more specifically, the competitiveness of the present manufacturing industry can be improved, and other substantive benefits can be increased.

Description

technical field [0001] The invention relates to a tool structure, especially a tool structure that can effectively save processing time, improve product qualification rate, and reduce manufacturing cost burden. Background technique [0002] The manufacturing industry is the hub of a country's industrial development. The manufacturing of many products depends on the manufacturing and forming of cutting tools, such as: turning tools, milling cutters, boring tools, taps, drills, etc. Different cutting tools have their own specific cutting tools. Function, and depending on the complexity of processing, product forming must rely on the combination of various cutting tools to form. [0003] For example: for the production of internal threaded holes, first use the positioning drill to perform chamfering and positioning holes on the processed object, then use the drill bit to drill the positioning holes, and then use the tap to tap along the drilled holes to facilitate the drilling....

Problems solved by technology

[0006] However, although this existing Chinese Taiwan Announcement No. 256128 "Drilling, Car Hole, Milling Simultaneous Chamfering and Trimming Device" that can be changed at will has the concept of two kinds of cutter combinations to process synchronously, the cutter of its chamfering is The sleeve and the bolt are locked on the drill bit, turning tool, milling cutter or tapping head. When drilling, turning, milling or tapping, etc., vibration will be generated. After a period of use, the lock on the The chamfering tool of the drill bit, turning tool, milling cutter or tapping head will loosen, which will affect the qualified rate of the processed product. Therefore, it is necessary to perform tool calibration every time during construction. In this way, the processing accuracy will also be improved. Disadvantages such as poor and increased processing hours, and the Chinese Taiwan Announcement No. 256128 "Drilling, turning, milling and chamfering, trimming device that can be changed at will" is only limited to drilling, turning, and milling in implementation. Or double-effect processing of simultaneous chamfering during tapping, etc., still cannot effectively break through more than three processing steps, so when it is desired to perform processing that can only be formed by combining more than three cutting tools, such as: internal thread holes, etc., the Chinese Taiwan Announcement No. 256128 "Drilling, Hole Turning, Milling Simultaneous Chamfering and Trimming Device" is not applicable, so it still needs to go through cumbersome tool changing procedures, which will affect the working hours, pass rate and cost of processing, etc.

[0007] Therefore, in view of the fact that complex machining such as threaded holes requires cumbersome tool change procedures, resulting in disadvantages such as increased man-hours, product defect rates, and increased manufacturing costs, the inventors made use of their many years of manufacturing and design in related fields. With the assistance of experience and knowledge, and through various ingenuity, the research and development and improvement of existing cutting tools have been done, and the invention has been developed.
