Detailed Implementation Modes

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Referring to Figure 1 - Figure 2 Figure 1 - Figure 2 , an embodiment provided by the present utility model: A high-efficiency tapping device for metal hardware parts, including a workbench 1, a material blocking frame 2 is fixedly connected to the upper end of the workbench 1, a tapping machine 3 is fixedly connected above the workbench 1, a tapping tool 4 is fixedly connected to the bottom output end of the tapping machine 3. When the tapping machine 3 is started, it can drive the tapping tool 4 to move downward and rotate, and can tap the workpiece. This is an existing technical means in the art and will not be elaborated here.

[0032] Referring to Figure 1 - Figure 3 Figure 1 - Figure 3 , a through groove 5 is opened on the upper surface of the workbench 1, a protective cylinder 6 is fixedly connected inside the through groove 5, the protective cylinder 6 is located directly below the tapping tool 4, a fixed hopper 7 is fixedly connected to the bottom end of the protective cylinder 6, and a clamping unit is arranged outside the protective cylinder 6. The clamping unit includes an electric push rod 81, and the electric push rod 81 is fixedly connected to the inner surface of the material blocking frame 2. One end of the electric push rod 81 close to the protective cylinder 6 penetrates through the protective cylinder 6, and a clamping plate 82 is fixedly connected to the end of the electric push rod 81 close to the protective cylinder 6. The number of electric push rods 81 is two, and the two electric push rods 81 are respectively fixedly connected to the left and right inner wall surfaces of the material blocking frame 2. When the electric push rod 81 is started to drive the clamping plate 82 to move towards the workpiece placed inside the fixed hopper 7, the workpiece can be clamped and fixed. When the workpiece is completely clamped, due to the hopper-shaped structure of the fixed hopper 7, the bottom end of the workpiece can only be in linear contact with the inner wall surface of the fixed hopper 7, so that the center of the bottom end of the workpiece is in a suspended state, avoiding contact between the tapping tool 4 and the workbench 1 when penetrating the workpiece, resulting in unnecessary wear. At the same time, the cooling water used for cooling during processing will also completely enter the inside of the fixed hopper 7 and flow downward for storage.

[0033] A shielding unit is arranged at the bottom end of the tapping machine 3. When the tapping machine 3 is started to drive the tapping tool 4 to move downward for tapping, it will drive the shielding unit to move synchronously. The shielding unit includes an elastic member 91, and the elastic member 91 is fixedly connected to the bottom end of the tapping machine 3. A circular baffle 92 is fixedly connected to the bottom end of the elastic member 91. When the circular baffle 92 moves downward, it will squeeze the elastic member 91, causing the elastic member 91 to be compressed to generate elastic potential energy. The circular baffle 92 is sleeved outside the tapping tool 4, and the tapping tool 4 can move downward through the center of the circular baffle 92. A sealing ring 93 is fixedly connected to the bottom end of the circular baffle 92, and the size of the sealing ring 93 is adapted to the size of the protective cylinder 6. When the shielding unit moves downward, the protective cylinder 6 will squeeze the circular baffle 92, causing the circular baffle 92 to move downward, and then squeezing the elastic member 91. At this time, the circular baffle 92 can shield the inside of the protective cylinder 6 while not affecting the downward movement of the tapping tool 4 for tapping, reducing the situation of debris splashing to the outside during tapping and causing environmental pollution.

[0034] At the inner bottom end of the workbench 1, a collection cylinder 10 is provided. The bottom of the collection cylinder 10 can be set as a bolt-fixed bottom plate, which can be directly taken out, disassembled and cleaned. The collection cylinder 10 is located directly below the fixed hopper 7, and the bottom surface of the fixed hopper 7 is in mutual fit with the upper surface of the collection cylinder 10. During the processing, the cooling water mixed with debris will flow downward through the fixed hopper 7 and enter the interior of the collection cylinder 10 for collection and treatment.

[0035] Referring to Figure 2 - Figure 4 , filter holes 11 are provided on the outer side of the upper end of the collection cylinder 10. When the cooling water mixed with debris enters the interior of the collection cylinder 10, as the cooling water increases, it will overflow through the filter holes 11 to filter the cooling water. The filtered cooling water that overflows can be recycled, and the debris with a large density will settle downward, which can reduce the situation of the filter holes 11 being blocked by debris. An annular frame 12 is fixedly connected to the outer side of the collection cylinder 10. The cooling water that overflows through the filter holes 11 will flow into the interior of the annular frame 12, which can reduce the contact between the debris and the filter holes 11, and thus reduce the possibility of the filter holes 11 being blocked. A drainage hose 13 is fixedly connected to the left end of the annular frame 12. The left inner wall surface of the workbench 1 is fixedly connected with a water tank 14. The left end of the drainage hose 13 is fixedly connected to the right surface of the water tank 14. A circulation pump is fixedly connected to the outer side of the drainage hose 13, which can pump the cooling water in the annular frame 12 into the water tank 14.

[0036] A connecting pipe 15 is fixedly connected to the left end of the water tank 14. A pressure pump 16 is fixedly connected to the left surface of the tapping machine 3. The left end of the connecting pipe 15 penetrates through the workbench 1, and the left end of the connecting pipe 15 is fixedly connected to the left water inlet end of the pressure pump 16. The bottom end of the pressure pump 16 is fixedly connected with a water outlet hose 17. The water flow in the water tank 14 will be discharged from the bottom end of the water outlet hose 17 through the connecting pipe 15. Starting the pressure pump 16 can pressurize the water flow so that the cooling water is sprayed onto the tapping area for cooling. The bottom end of the water outlet hose 17 penetrates through the annular baffle 92, and the annular baffle 92 is fixedly connected to the water outlet hose 17, which can keep the bottom end of the water outlet hose 17 at a certain distance from the workpiece all the time, and the telescopic property of the hose material of the water outlet hose 17 can avoid hindering the movement of the annular baffle 92.

[0037] Working principle: Place the hardware workpiece inside the protective cylinder 6, clamp and fix the workpiece through the clamping unit, and make the bottom end of the workpiece in an overhead state through the fixed hopper 7 to avoid unnecessary wear caused by contact between the tap 4 and the workbench 1 when the tap moves downward for tapping. When the tapping machine 3 starts and drives the tap 4 to move downward for processing, the provided shielding unit can shield the upper end of the protective cylinder 6 to reduce the splashing of debris during the processing, thereby reducing environmental pollution. The debris and the used cooling water can flow downward through the fixed hopper 7 into the collection cylinder 10 for collection and filtration. The debris will settle at the bottom of the collection cylinder 10, and the cooling water will gradually filter through the filter holes 11 and overflow into the inside of the annular frame 12, and then be recycled through the drain hose 13, water tank 14, connecting pipe 15, pressure pump 16 and outlet hose 17 to avoid wasting water resources.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
