When the workpiece is required to be tapped, an operator starts the tapping machine body 3, and drives the chip suction cover 5 and the tapping cone 4 to move downwards continuously through the tapping machine body 3, so that the bottom of the penetrating cylinder 7 is abutted with the top of the workpiece. In the tapping process, the tapping cone 4 continuously moves towards the bottom of the workpiece, and meanwhile, the sleeve 6 also continuously moves downwards, so that the cavity in the double-wall sandwich structure in the sleeve 6 is driven to continuously move downwards, and at the moment, the penetrating cylinder 7 continuously penetrates into the cavity in the double-wall sandwich structure of the sleeve 6 to move. This kind of design mode prevents, collects through sleeve 6 and wear to establish a section of thick bamboo 7 the metal chip that the tapping produced, when tapping tap 4 carries out the tapping operation, wear to establish the bottom of section of thick bamboo 7 all with work piece top butt all the time, sleeve 6 and tapping awl 4 all along with tapping machine body 3 vertical motion, constantly overlap to establish and wear to establish a section of thick bamboo 7, wear to establish the different degree of depth of entering the work piece when tapping tap 4 and all can seal and keep off, prevent that metal chip from outwards splashing constantly harm operating personnel's personal safety to prevent to make the processing environment messy.

As shown in fig. 2, two opposite springs 8 are fixedly arranged at the top in the cavity of the double-wall interlayer of the sleeve 6, and the bottom ends of the two springs 8 are fixedly connected with the top of the penetrating cylinder 7. When the tapping cone 4 continuously taps downwards, the bottom of the penetrating cylinder 7 is always in butt joint with the top of a workpiece, the sleeve 6 continuously moves downwards along with the tapping machine body 3, the tops of the two springs 8 are provided with downward pressure through the sleeve 6, and the bottom of the penetrating cylinder 7 is provided with upward supporting force through the top of the workpiece. This kind of design mode passes through two kinds of power interact to make the support of wearing to establish a section of thick bamboo 7 more firm, avoid wearing to establish the bottom of a section of thick bamboo 7 and appear the gap between the work piece, better keep off the collection to the metal piece. As shown in fig. 2, a circle of rubber cushions 19 distributed along the circumferential direction is arranged at the bottom of the penetrating cylinder 7. When the bottom of the penetrating cylinder 7 abuts against the top of the workpiece, the rubber cushion 19 also abuts against the top of the workpiece. The design method avoids the generation of gaps between the penetrating cylinder 7 and the workpiece, thereby avoiding the flying-out of splashed metal scraps from the gaps, endangering the personal safety of operators and causing mess of processing environment.

As shown in fig. 2, a positioning ring 9 coaxial with the positioning ring is fixedly arranged below the inner wall of the penetrating cylinder 7, two vertical connecting rods 10 are fixed on the positioning ring 9, an ash removing ring 11 coaxial with the positioning ring 9 is fixedly arranged on the connecting rods 10, the outer wall of the ash removing ring 11 is abutted with the inner wall of the sleeve 6 and can vertically slide relative to the inner wall of the sleeve 6, the tapping cone 4 rotates to penetrate through the ash removing ring 11, and the tapping cone 4 can penetrate through the positioning ring 9. When the tapping cone 4 continuously moves towards the bottom of a workpiece, the bottom of the penetrating cylinder 7 is always in butt joint with the top of the workpiece, the tapping machine body 3 drives the sleeve 6 to continuously move downwards relative to the ash cleaning ring 11, the outer wall of the ash cleaning ring 11 is always in butt joint with the inner wall of the sleeve 6, metal scraps splashed onto the inner wall of the sleeve 6 in the tapping process are continuously scraped upwards, and the metal scraps on the inner wall of the sleeve 6 are cleaned through cooperation with the exhaust assembly. According to the design mode, the two connecting rods 10 are used for installing and positioning the ash removing ring 11 and the penetrating cylinder 7, so that the ash removing ring 11 can always keep abutting joint with the inner wall of the sleeve 6, and the effect of scraping metal scraps by the ash removing ring 11 is better; still through making sleeve 6 for the vertical motion of deashing ring 11, make deashing ring 11 scrape the metal piece, simple structure, be convenient for operate, on the certain circumstances, the piece that produces in the tapping process can be got rid of the inner wall of sleeve 6, this part piece can be scraped to deashing ring 11 this moment to, after long-time use, can adhere some dust on the inner wall of sleeve 6, the dust on the inner wall of sleeve 6 also can be scraped to the setting of deashing ring 11 this moment.

As shown in fig. 1 and fig. 2, the top of the sleeve 6 is provided with an air distribution cavity 12, one side of the air distribution cavity 12 is provided with a plurality of air inlet holes 13, a plurality of air inlet holes 13 are communicated with a cavity in the sleeve 6, the air suction assembly comprises an air suction fan 14 and an air suction box 15, the air suction fan 14 is arranged on the tapping machine body 3, the air suction end of the air suction assembly is provided with an air suction pipe 16, one side of the air suction box 15 is connected with an air inlet pipe 17 in a conducting manner, the end part of the air inlet pipe 17 is connected with the air distribution cavity 12 in a conducting manner, the other side of the air suction box 15 is connected with the air suction pipe 16 in a conducting manner, and a filtering piece 18 for filtering scraps is arranged in the air suction box 15. When the tapping operation is required to be carried out on a workpiece, an operator starts the exhaust fan 14, the exhaust end of the exhaust fan 14 is used for exhausting air into the exhaust box 15 through the exhaust pipe 16, the exhaust box 15 is used for supplying air through the air inlet pipe 17, the air inlet pipe 17 is used for supplying air through a plurality of air inlets Kong Jinfeng which are connected with the air distribution cavity 12 in a conducting mode, and then the sleeve 6 is used for exhausting and collecting splashed metal scraps in the penetrating cylinder 7. After the metal scraps collected by the air suction enter the air suction box 15, the metal scraps are filtered and blocked by the filter element 18. The design mode is that the exhaust fan 14 is used for exhausting the metal scraps splashed in the sleeve 6 and the penetrating cylinder 7, so that the metal scraps can be collected intensively, and the metal scraps are prevented from being scattered and accumulated, and environmental pollution is avoided; also, the filter element 18 facilitates the protection of the collected metal chips from damage caused by the metal chips entering the suction fan 14. As shown in fig. 1, the filter 18 is a filter screen structure. This kind of design mode can make filter 18 filter better, prevent keeping off the metal chip that enters into in the suction box 15, makes filter 18's filter effect better to filter 18 is this kind of specific structure of filter screen, and the cost of manufacture is lower.
