[0002] Screw machining refers to the process of creating threads on metal or plastic workpieces. This process usually involves cutting or forming threads on the workpiece surface or in a hole so that a screw or nut can mate with it to form a fastened connection. In order to ensure that the thread size and shape of each workpiece are consistent, a tapping device is required.

[0003] The prior art has the following defects: in the production and processing of the existing tapping device, since some tapping devices have no protective measures, there may be excessive cutting force that causes the tool to be overloaded and break and severe tool wear, and vibration or external impact may cause the tool to be subjected to additional stress, etc., which will cause the tool to splash and easily cause harm to the workers. In addition, cooling water is used in the tapping project. Since the cooling water collides with the surface of the workpiece during use and splashes, it is easy to affect the surrounding working environment. Therefore, a tapping device for screw processing is proposed to solve the above problems. Utility Model Content

[0028] Reference Figure 1 、 Figure 2 and Figure 4, the top of the operating table 1 is provided with a through slot 4, which is in multiple groups, so that cooling water and waste chips can pass through the through slot 4 into the operating table 1 for separation. A filter frame 10 is plugged into the inner wall of the operating table 1, and a filter screen is provided on the filter frame 10. The solid-liquid separation of waste chips and cooling water is carried out through the filter screen to avoid the tedious operation of subsequent manual processing. The top inner wall of the filter frame 10 is elastically connected to a handle 12 through a positioning spring 11. The handle 12 allows the filter frame 10 to be installed and disassembled from the operating table 1. The side wall of the operating table 1 is fixedly connected with a fixing block 13. The top inner wall of the filter frame 10 is fixedly connected to one end of the positioning spring 11. When the handle 12 moves upward, the positioning spring 11 is compressed. When resetting, the elastic force of the positioning spring 11 is used to reset the handle 12. The other end of the positioning spring 11 is fixedly connected to the top of the handle 12. The handle 12 is slidably connected to the inner wall of the filter frame 10. The bottom end of the handle 12 is plugged into the inner wall of the fixed block 13. The bottom end of the handle 12 is raised, and the fixed block 13 is provided with a notch corresponding to the raised portion, so that the raised portion and the notch can be plugged into each other to limit the entire filter frame 10.

[0029] Reference Figure 1-Figure 3 The limiting mechanism includes a card block 8, and the shielding plate 6 is provided with a slot corresponding to the card block 8, which can allow the card block 8 to move laterally along the socket when in use. The card block 8 is slidably connected to the inner wall of the shielding plate 6, and the right end of the card block 8 is elastically connected to the shielding plate 6 through a return spring 7. The right end of the card block 8 is fixedly connected to one end of the return spring 7. When the card block 8 moves to the right, the return spring 7 is compressed. When resetting, the elastic force of the return spring 7 is used to restore the card block 8. The other end of the return spring 7 is fixedly connected to the inner wall of the right end of the shielding plate 6, and the card block 8 is engaged with the inner wall of the U-shaped groove 9.

[0030] Working principle: First, in order to prevent the tool from breaking and cooling water splashing during the processing of the tapping machine 3, it is only necessary to place the workpiece on the fixture 2 and fix it, and then move the block 8 to the right and compress the reset spring 7 to separate the block 8 and the lower horizontal opening of the U-shaped groove 9, and let the reset spring 7 move the baffle 6 upward along the vertical opening of the U-shaped groove 9 to increase the protection height so that the entire processing area is blocked by the sleeve plate 5 and the baffle 6. At this time, move the block 8 to the left to make the block 8 coincide with the upper horizontal opening of the U-shaped groove 9, and use the reverse elastic force of the reset spring 7 to keep the block 8 and the upper horizontal opening of the U-shaped groove 9 continuously engaged, so as to avoid the situation where the tool splashes and the staff are injured, and the cooling water splashes affect the working environment.

[0031] During processing, cooling water and some waste chips will flow into the operating table 1 through the through groove 4, and the waste chips and cooling water will be separated by the filter screen on the filter frame 10, and the cooling water will flow out through the pipe on the side of the operating table 1 and be collected and recycled. When the filter screen on the filter frame 10 needs to be cleaned, just move the handle 12 upward and compress the positioning spring 11 to separate the bottom end of the handle 12 from the fixed block 13, and then use the handle 12 to move the filter frame 10 out of the inner wall of the operating table 1. When installing, just follow the above steps to plug the filter frame 10 into the inner wall of the operating table 1. When the bottom end protrusion of the handle 12 coincides with the fixed block 13, release the handle 12 and use the reverse elastic force of the positioning spring 11 to reset the handle 12, and plug the bottom end of the handle 12 into the inner wall of the fixed block 13.

[0032] After the processing is completed, release the limit of the block 8 according to the above steps in the first section, and let the shielding plate 6 return to Figure 1 The status shown is OK.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
