Drill bit structure device capable of forming countersunk holes at one time

The creation department mainly provides a bit structure device which can be processed at one time to form a countersunk hole, in particular, a drilling process can be completed at the same time by only one drilling operation, that is, only one processing step can be performed. Complete the processing of the countersink, it is a unique, convenient and economical creator.

Press, in the general processing of the countersunk hole 803 (see Figure 6B) processing steps, you must first use the drill bit to drill a through hole in the workpiece, then remove the drill bit and change the milling After the knife, in the center position of the original drilled through hole, the machining step of the milling cutter is performed, so that the machining operation of the counterbore 803 can be completed after 2 steps and 2 times of cutting the tool. However, the structure is similar. And the processing steps still have the following disadvantages in use:

1. Since the conventional processing method requires two processing steps, the processing is inaccurate or the processing fails due to human factors.

2. Since the conventional processing method requires two processing steps, this will increase the time required for processing.

Since the structure and processing steps of the conventional use still have many of the above-mentioned shortcomings in use, the creator of this article has devoted himself to the experience of many years and has created the creation case, which is to solve the shortcomings of the application. And to enhance its unprecedented progress and practicality, however, the technical means of how to solve the difficulties of using this creation are as follows:

1. Please refer to Fig. 1 and Fig. 2, since the bit structure 5 of the present invention has a machining tool in which the drill bit 3 and the milling cutter 2 are integrated at the same time, when the countersunk hole as shown in Fig. 6B is to be processed, At 803, it is only necessary to perform the machining step once as shown in Fig. 6A, and the drilling and milling processing stroke can be completed at the same time to obtain the required counterbore 803, without the need to change the tool separately, thus solving the problem. The shortcomings of inaccurate processing or processing failure due to human factors.

2. Please refer to FIG. 6A and FIG. 6B. Since the bit structure 5 of the present invention requires only one processing step, the processing stroke of the drilling and the milling hole can be completed at the same time, that is, the processing of the countersink 803 can be completed in one process. It is not necessary to complete the drilling and machining steps after drilling and replacing the tools separately, so that the shortcomings of the conventional processing time can be solved.

The main purpose of the present invention is to provide a bit structure device capable of forming a countersunk hole at one time, so that the drilling process of drilling and milling can be completed at the same time with only one processing step, that is, the process can be completed in one process. The processing of the head hole to save time required for processing.

The secondary purpose of this creation is to provide a bit structure device that can be formed into a countersunk hole at one time, so that when the countersunk hole is processed, it is not necessary to replace the tool twice to increase the yield of the processing.

In order to provide a more detailed and clear understanding of the purpose, function, and structural features of the present invention, the preferred embodiments are described below and described in conjunction with the drawings. Referring to FIG. 1 , FIG. 2 and FIG. 3 , the present invention mainly provides a bit structure device capable of forming a countersunk hole at one time, mainly by a rod body 1, a milling cutter 2, a drill bit 3 and a positioning bolt. 4, wherein: the rod body 1 has a cylindrical shape, and has a cylindrical clamping portion 101 at one end thereof, and the clamping portion 101 has a platform 102 extending toward the other end, and the platform 102 is scribed There is a size area 104, and the other end of the rod body 1 has a threaded rod 103, the thread of which is a left-hand thread.

The milling cutter 2 has a second-order cylindrical shape, and has a protruding rod 201 at one end thereof. The protruding rod 201 has a threaded hole 203 at a suitable circumference, and a U-shaped hole 202 at a central portion of the protruding rod 201. The U-shaped channel 202 can be sleeved on the rod body 1 and can be moved back and forth on the platform 102 of the rod body 1. The other end of the protrusion rod 201 has two milling cutter edges 204 on the circumference.
