[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the new machine tap comprises a tap body 1 and a tap head 2. The tap body 1 and the tap head 2 are detachable and split structures. A plug-in column 3 is provided at the end of the tap head 2 for quick plug-in connection. A connecting groove 4 is provided at the end of the tap body 1 for plugging in the plug-in column 3. A connecting mechanism for improving the connection strength and for radial limiting is provided between the tap body 1 and the tap head 2. A plurality of adjusting members 5 for axial limiting and fastening are movably provided on the peripheral wall of the tap head 2. The adjusting member 5 penetrates the side wall of the tap head 2 and penetrates into the connecting groove 4 to connect with the plug-in column 3. 3 cooperate with each other, the connection mechanism includes an elastic washer 6 for improving the elastic fixation of the tap body 1, a plurality of limit posts 7 for radial limit, and an elastic member 8 for elastic reset, a guide hole 10 for installing the plurality of elastic members 8 and guiding and cooperating with the limit posts 7 is opened on the side wall of the tap head 2, and a gasket 9 is arranged in the guide hole 10. The structure is simple in design and is in a detachable split structure, which can effectively reduce the overall scrapping of the tap caused by chipping and disordered teeth, reduce the use cost of the tap, and can replace a variety of tap heads 2 according to actual conditions, and has a wide range of applications.

[0023] How it works

[0024] The novel tap changes the traditional one-piece structure design of taps, and improves it into a split structure of the tap head 2 and the tap body 1. Even if the tap head 2 breaks, there is no need to disassemble the entire tap, and only the tap head 2 needs to be disassembled and replaced to carry out processing. After replacing the tap head 2, processing can be carried out directly, and there is no need to calibrate after replacing the tap as in the traditional way. Moreover, a variety of tap heads 2 can be replaced according to actual conditions, which greatly improves processing efficiency and reduces the cost of tap damage. At the same time, the connection mechanism, the adjustment member 5 and the matching hole 11 structure are used to effectively realize the axial and radial fastening connection between the tap head 2 and the tap body 1.

[0025] To further elaborate, in order to improve the axial limiting connection strength of the tap body 1 and the tap head 2, a plurality of matching holes 11 that are mutually limited with the adjusting member 5 are opened on the outer peripheral wall of the plug-in column 3, and the adjusting member 5 is movably arranged on the side wall of the tap head 2. The adjusting member 5 realizes axial fixation and disassembly of the tap body 1 and the tap head 2 by cooperating with the matching holes 11. The above structure can effectively realize the axial limiting connection.

[0026] To elaborate further, in order to facilitate the radial limiting connection between the tap body 1 and the tap head 2, and at the same time, to facilitate the disassembly and positioning installation of the tap body 1, the elastic washer 6 is provided with a plurality of through holes 12 for the limiting posts 7 to penetrate. The limiting posts 7 are fixed on the tap body 1 and penetrate into the through holes 12 and the guide holes 10 in sequence. A plurality of limiting posts 7 are arranged and distributed in a circumferential direction along the central axis of the tap body 1 at intervals. The number of limiting posts 7, through holes 12 and guide holes 10 are all 4. One end of the limiting post 7 is fastened to the tap spindle body, and the other end passes through the elastic washer 6 and cooperates with the guide hole 10.

[0027] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0028] Although the term ", " and " are used more frequently in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
