Description

Technical Field

[0001] The utility model belongs to the technical field of taps, and particularly relates to a flexibly replaceable tap. Background Art

[0002] A tap is a tool for processing internal threads. According to its shape, it can be divided into spiral groove taps, blade angle taps, straight groove taps and pipe thread taps. According to the use environment, it can be divided into hand taps and machine taps. According to specifications, it can be divided into metric, American and imperial taps.

[0003] Taps are widely used in the process of mechanical processing and are the most mainstream processing tools used by manufacturing operators when tapping. The existing taps on the market generally adopt an integrated fixed structure design, that is, a tap only contains a fixed tap head and size length. However, in the actual processing process, due to differences in processing depth, chip removal method, through holes and blind holes, etc., it is necessary to replace taps of different styles and lengths for processing, which not only increases the difficulty of processing and reduces processing efficiency, but also requires the processor to purchase a variety of taps of different styles and lengths to meet processing needs. Considering the wear and breakage of the tap during processing, the same model of taps needs to be purchased repeatedly, which increases the cost of processing. Utility Model Content

[0004] The purpose of the utility model is to provide a flexibly replaceable tap in view of the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a flexibly replaceable tap, comprising a tap head and a tap handle, the end of the tap head and the front end of the tap handle form a mortise and tenon structure that cooperates with each other, the mortise and tenon structure includes a tenon, a tenon shoulder and a mortise, the tenon and the mortise on the end of the tap head and the mortise and the tenon on the front end of the tap handle are mutually embedded, the tenon shoulder at the end of the tap head and the tenon shoulder at the front end of the tap handle are formed with corresponding threaded through holes, a fastening screw is matched in the threaded through hole, and the fastening screw and the nut cooperate with each other to split and fasten the mortise and tenon structure.

[0006] In the above-mentioned flexibly replaceable tap, a positioning head is formed at the front end of the tap head, a thread is formed behind the positioning head, a cutting cone is formed at the front end of the thread, and a chip removal groove is formed on the tap head.

[0007] In the above-mentioned flexibly replaceable tap, the tap head can be divided into a spiral groove tap head, a blade inclination angle tap head, and a straight groove tap head according to the shape.

[0008] In the above-mentioned flexibly replaceable tap, four corners are formed at the end of the tap handle.

[0009] In the above-mentioned flexibly replaceable tap, the tap shank can be processed into models with any length.

[0010] Compared with the prior art, the flexibly replaceable tap provided by the utility model improves the integrated fixed structure of the traditional tap, and the tap head and the tap handle form a detachable modular structure through the mortise and tenon structure connection, and the connection has a high strength. According to different processing requirements, the utility model can be combined by replacing different styles of tap heads and different lengths of tap handles to achieve the purpose of flexibility and efficiency, while reducing the processing cost of purchasing multiple fixed models of taps.

[0015] 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.

[0016] like Figures 1 to 3 As shown, the flexibly replaceable tap includes a tap head 1 and a tap handle 3, and a mortise and tenon structure 2 that cooperates with each other is formed at the end of the tap head 1 and the front end of the tap handle 3. The mortise and tenon structure 2 includes a tenon 23, a tenon shoulder 24 and a mortise 25. The tenon 23 at the end of the tap head 1 is engaged with the mortise 25 at the front end of the tap handle 3, and the tenon 23 at the front end of the tap handle 3 is engaged with the mortise 25 at the end of the tap head 1. The tenon shoulder 24 at the end of the tap head 1 and the tenon shoulder 24 at the front end of the tap handle 3 form corresponding threaded through holes 26, and a fastening screw 21 is matched in the threaded through hole 26. The fastening screw 21 and the nut 22 cooperate with each other to realize the disassembly and fastening of the mortise and tenon structure 2. The mortise and tenon structure 2 not only makes the tap head 1 and the tap handle 3 form a detachable modular structure, which is convenient for flexible disassembly and assembly, but also has a high structural strength after being assembled and fixed, and avoids loosening and falling off when the tap is rotated for tapping.

[0017] like Figure 1 to Figure 2 As shown, a positioning head 11 is formed at the front end of the tap head 1, which can locate the position of the hole before the tap is tapped. A thread 13 is formed behind the positioning head 11, and a cutting cone 12 is formed at the front end of the thread 13. The cutting cone 12 can tap the tap into the hole, and then the thread 13 performs tapping on the hole wall. A chip groove 14 is formed on the tap head 1, and the generated chips can be discharged through the chip groove 14 to avoid affecting the processing. The tap head 1 can be divided into a spiral groove tap head, a blade inclination angle tap head, a straight groove tap head, etc. according to the shape. In the actual processing process, different tap heads 1 can be selected according to the conditions of the hole.

[0018] In further detail, the end of the tap handle 3 is formed with four corners 4 for fixing on a tap wrench or a tapping machine for tapping. The tap handle 3 can be processed into models of any length to adapt to the processing of holes of different depths.

[0019] The working principle of the utility model is as follows: when a combined tap needs to be replaced after use, the fastening screw 21 and the nut 22 on the mortise and tenon structure 2 can be unscrewed to separate the mortise and tenon structure 2, and a tap head 1 of another required style or a tap handle 3 of a required length can be selected. Then, the replaced tap head 1 and tap handle 3 can be reassembled with the fastening screw 21 and the nut 22 for use.

[0020] 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.

[0021] Although various terms 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.
