[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Existing tapping equipment for nut processing generates intense friction between the tap and the workpiece during nut processing. This causes the tap's cutting edge to wear down rapidly, reducing its lifespan. Additionally, metal filings may clog the threaded hole or tap groove, further impacting processing efficiency.

[0023] In view of this, the present invention provides a tapping device for nut processing. This tapping device, through the cooperation of a first housing, an oil injection pump, a support base, an oil storage pipe, a first connecting pipe, a rotating pipe, an operating column, an oil distribution pipe, and an oil injection pipe, achieves the effect of the oil injection pump drawing lubricating oil from the first housing into the oil storage pipe when nut processing is required, and then spraying lubricating oil onto the thread tap through the oil distribution pipe and the oil injection pipe. This solves the problem in existing tapping devices for nut processing where there is strong friction between the tap and the workpiece, causing rapid wear of the tap's cutting edge and reducing its service life. Additionally, metal filings may clog the threaded hole or tap groove, thus affecting processing efficiency.

[0024] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly introduced below.

[0025] Example 1, by Figure 1-5 As can be seen, the tapping equipment for nut processing in this case includes an operating box 1, a threaded taper 5 is provided on the top of the operating box 1, and four movable wheels 6 are fixedly connected to the bottom corners of the operating box 1. The tapping equipment for nut processing also includes an oil spraying device 2; the oil spraying device 2 is located on one side above the operating box 1; a recycling device 3 is located below the threaded taper 5; and a tapping device 4 is located on the side above the operating box 1 away from the oil spraying device 2. The tapping device 4 processes the inner wall of the nut, the oil spraying device 2 sprays lubricating oil onto the outer wall of the threaded taper 5, and the recycling device 3 recycles and reuses the excess lubricating oil.

[0026] In the specific implementation process, it is worth noting that the material of the thread taper 5 is high-speed steel or cemented carbide to ensure the hardness and toughness of the thread taper 5, to ensure good machinability of the thread taper 5, and to withstand high cutting speeds and impact tests. The overall material of the operating box 1 can be carbon steel or cast iron to ensure the stability and load-bearing capacity of the operating box 1. The operating box 1 supports the entire tapping equipment. The oil spraying device 2 sprays lubricating oil onto the surface of the thread taper 5. The lubricating oil reduces the friction between the thread taper 5 and the nut, making the thread taper 5 smoother during the cutting process. The recycling device 3 recovers the lubricating oil dripping from the thread taper 5, filters it, and puts it back into the oil spraying device 2. The tapping device 4 then processes the nut.

[0027] Furthermore, the oil injection device 2 includes a first housing 21; the entire material of the first housing 21 can be stainless steel to ensure the overall corrosion and oxidation resistance of the first housing 21, prevent the inner wall of the first housing 21 from rusting and contaminating the lubricating oil, and the first housing 21 is fixedly connected to the bottom of the inner wall of the operating box 1; the oil injection pump 22 is located inside the first housing 21, and the oil injection pump 22 is a type B pump to ensure that it can meet the actual use requirements for extracting lubricating oil; the support base 23 is fixedly connected to the top side of the operating box 1; the oil storage pipe 24 is connected to the top of the support base 23; the first connecting pipe 25 passes through the support base 23 and is connected to the bottom of the oil storage pipe 24; The rotating pipe 26 is rotatably connected to the top of the oil reservoir 24 via a sealed bearing; the operating column 27 is rotatably connected to the top of the outer wall of the oil reservoir 24 via a bearing and is located below the rotating pipe 26; the oil distribution pipe 28 is connected to the side of the rotating pipe 26 near the threaded cone 5; the oil spray pipe 29 is connected to the bottom of the oil distribution pipe 28 near the threaded cone 5 and extends to the upper side of the threaded cone 5; wherein, through the cooperation between the first housing 21, the oil injection pump 22, the support base 23, the oil reservoir 24, the first connecting pipe 25, the rotating pipe 26 and the operating column 27, the lubricating oil is transported to the interior of the rotating pipe 26, and the lubricating oil is sprayed through the oil distribution pipe 28 and the oil spray pipe 29;

[0028] In the specific implementation process, it is worth noting that the first housing 21 is filled with lubricating oil, which lubricates and cools the threaded taper 5, extending its service life. An oil replenishment port is connected to the side of the first housing 21 away from the threaded taper 5. The lubricating oil in the first housing 21 is replenished through an on / off valve on the oil replenishment port. The bottom of the oil storage pipe 24 is connected to the first connecting pipe 25 via a pipe joint. A crossbar is fixedly connected to the outer wall of the rotating pipe 26, and the crossbar is fixed to the operating column 27 by a pin. A vertical plate is fixedly connected to the outer wall of the oil distribution pipe 28, and the vertical plate is fixedly connected to the top of the operating column 27. The vertical plate distributes the oil... The pipe 28 provides support, and the bottom of the oil injection pipe 29 is angled and extends to both sides of the threaded cone 5, which facilitates the spraying of lubricating oil onto the surface of the threaded cone 5. Through the cooperation between the first housing 21, the oil injection pump 22, the support base 23, the oil storage pipe 24, the first connecting pipe 25, the rotating pipe 26, and the operating column 27, when it is necessary to spray oil onto the threaded cone 5, the oil injection pump 22 transports the lubricating oil in the first housing 21 to the inside of the oil storage pipe 24 through the first connecting pipe 25. The lubricating oil inside the oil storage pipe 24 enters the inside of the oil distribution pipe 28 through the rotating pipe 26 and is sprayed onto both sides of the threaded cone 5 through the oil injection pipe 29.

[0029] Furthermore, the recycling device 3 includes a hydraulic cylinder 31. The model of the hydraulic cylinder 31 is selected according to actual needs, as long as it meets the operational requirements. The hydraulic cylinder 31 is fixedly connected to the bottom pre-reserved groove of the operating column 27. The cover 32 is fixedly connected to the output end of the hydraulic cylinder 31. The motor 33 is fixedly connected to the inner wall of the cover 32 through a motor sleeve. The model of the motor 33 is selected according to actual needs, as long as it meets the operational requirements. First, the motor 33 is connected to an external power supply. The protective cover 34 is slidably snapped onto the outer wall of the cover 32. The filter plate 35 is located below the threaded cone 5 and embedded in the top of the operating box 1. The filter plate 35 is made of stainless steel to ensure its corrosion resistance and oxidation resistance, and to ensure that the filter plate 35 can be lubricated for a long time. The system operates while immersed in oil. A guide pipe 36 is fixedly connected to the top of the inner wall of the control box 1 and located below the filter plate 35. A filter device 37 is positioned below the guide pipe 36. A solenoid valve 38 is connected to the bottom of the first housing 21 near the guide pipe 36. The solenoid valve 38 is a type 131, ensuring it meets the requirements of actual use. A second connecting pipe 39 connects the solenoid valve 38 and the second housing 371. Through the cooperation of the hydraulic cylinder 31, cover 32, motor 33, protective cover 34, filter plate 35, and guide pipe 36, lubricating oil is recovered; the lubricating oil is filtered by the filter device 37; and the lubricating oil is recycled and reused through the solenoid valve 38 and the second connecting pipe 39.

[0030] In the specific implementation process, it is worth noting that the output end of the hydraulic cylinder 31 penetrates the bottom of the inner wall of the operating column 27 and is fixedly connected to the cover 32. Ventilation holes are provided on both sides of the top of the cover 32, allowing for heat dissipation of the motor 33. The protective cover 34 has a rectangular space composed of two horizontal plates and two vertical plates. The mesh size of the filter plate 35 is selected according to actual needs, meeting the working conditions. Nuts are machined on the top of the filter plate 35. Lubricating oil falls through the filter plate 35 under gravity, and the guide pipe 36 guides the lubricating oil through the hydraulic cylinder 31 and the cover. The cooperation between body 32, motor 33, protective cover 34, filter plate 35 and guide pipe 36 realizes the collection of excess lubricating oil, prevents the sprayed lubricating oil from splashing, and thus avoids the waste of lubricating oil and pollution of the working environment. The lubricating oil passes through filter device 37, which filters out impurities and metal debris in the lubricating oil, preventing impurities in the lubricating oil from clogging the pipes and oil injection pump 22. Solenoid valve 38 drives the second connecting pipe 39 to generate suction, and the lubricating oil enters the first box 21 through the second connecting pipe 39, realizing the reuse of lubricating oil.

[0031] Specifically, when the nut needs to be processed, the oil injection pump 22 transports the lubricating oil in the first housing 21 to the oil storage pipe 24 through the first connecting pipe 25. The lubricating oil inside the oil storage pipe 24 enters the oil distribution pipe 28 through the rotating pipe 26 and is sprayed on both sides of the threaded cone 5 through the oil injection pipe 29. The nut is processed on the top of the filter plate 35. The lubricating oil falls through the filter plate 35 under the action of gravity. The guide pipe 36 guides the lubricating oil. The filter device 37 filters out impurities and metal debris in the lubricating oil to prevent impurities in the lubricating oil from clogging the pipes and the oil injection pump 22. The solenoid valve 38 drives the second connecting pipe 39 to generate suction, and the lubricating oil enters the first housing 21 through the second connecting pipe 39.

[0032] Example 2, by Figure 1-5 It is known that the filter device 37 includes a second housing 371, the entire material of which can be stainless steel to ensure the corrosion resistance and oxidation resistance of the second housing 371, and to ensure that the second housing 371 will not rust; the second housing 371 is fixedly connected to the bottom of the inner wall of the operation box 1 on the side away from the first housing 21, and is connected to the end of the second connecting pipe 39 away from the solenoid valve 38; the filter screen 372 is fixedly connected to the lower inner wall of the second housing 371 by bolts, and is located above the second connecting pipe 39; multiple magnetic plates 373 are provided and are fixedly connected to the top of the inner wall of the second housing 371 at equal intervals; wherein, through the cooperation between the second housing 371, the filter screen 372 and the magnetic plates 373, the lubricating oil is recovered and filtered;

[0033] In the specific implementation process, it is worth noting that the mesh size of the filter screen 372 is selected according to actual needs, as long as it meets the working requirements. The magnetic plate 373 adsorbs the metallic impurities in the lubricating oil. The lubricating oil flows through the magnetic plate 373 to the surface of the filter screen 372. The filter screen 372 filters the impurities in the lubricating oil that have passed through the magnetic plate 373. The lubricating oil flows through the filter screen 372 to the bottom of the second box 371. Through the cooperation between the second box 371, the filter screen 372 and the magnetic plate 373, the effect of filtering impurities in the lubricating oil is achieved, which solves the problem that the collected lubricating oil contains a large number of impurities, which may clog the pipes or damage the fuel injection pump 22 when reused.

[0034] Furthermore, the tapping device 4 includes a first push rod 41; the first push rod 41 is fixedly connected to the top of the operating box 1 on the side away from the support base 23; a second push rod 43 is fixedly connected to the top of the operating box 1 on the side away from the first push rod 41; a feeding pipe 42 is disposed between the first push rod 41 and the second push rod 43, and is fixedly connected to the top of the operating box 1. The first push rod 41 and the second push rod 43 are both DT type electric push rods or DG series electric push rods, ensuring that the first push rod 41 and the second push rod 43 can meet the actual use requirements; two grippers 44 are provided, and are respectively fixedly connected to the output ends of the first push rod 41 and the second push rod 43; a pressing rod 45 is fixedly connected to the protective cover 34 near the support base. On one side of 23; the push switch 46 is fixedly connected to the bottom groove of the operating column 27, and the push switch 46 is of type LA10-2K; the contactor 47 is fixedly connected to the front of the outer wall of the operating column 27, and the contactor 47 is of type CTC series AC contactor; the controller 48 is fixedly connected to the side of the front of the outer wall of the operating column 27 away from the contactor 47, and the controller 48 can be of type SST-NS series; wherein, through the cooperation of the first push rod 41, the feeding pipe 42, the second push rod 43 and the gripper 44, the automatic feeding of the tapping device 4 is realized, and through the cooperation of the push rod 45, the push switch 46, the contactor 47 and the controller 48, the control of the electrical components of the tapping device 4 is realized;

[0035] In the specific implementation process, it is worth noting that the top of the feeding pipe 42 is fixedly connected to an opening that is wider at the top and narrower at the bottom, and the bottom is a hollow pipe. The nut is inserted from the top of the feeding pipe 42 and falls to the bottom. When the nut needs to be processed, the hydraulic cylinder 31 drives the cover 32 to descend, and the cover 32 drives the threaded cone 5 to descend to the surface of the nut. The motor 33 drives the threaded cone 5 to process the nut. At this time, the hydraulic cylinder 31 drives the push rod 45 to move away from the push switch 46. The push switch 46 controls the oil injection pump 22 to be energized and draw in lubricating oil. After completion, the hydraulic cylinder 31 drives the cover 32 to rise, and drives the push rod 45 to rise. Pressing switch 46 45 causes the oil injection pump 22 to be de-energized. Controller 48 controls the forward and reverse rotation of motor 33 via contactor 47. Motor 33 controls the tapping depth and cutting speed of thread taper 5. Through the cooperation between first push rod 41, feeding pipe 42, second push rod 43 and gripper 44, the first push rod 41 pushes the nut to the top of filter plate 35. The first push rod 41 and the second push rod 43 respectively drive the two grippers 44 to move towards each other and clamp the nut. After completion, the first push rod 41 returns to the initial position, and the nut inside the feeding pipe 42 falls to the bottom of the feeding pipe 42 under the action of gravity.

[0036] Specifically, when lubricating oil falls into the second housing 371 through the filter plate 35, the magnetic suction plate 373 adsorbs the metallic impurities in the lubricating oil, and the filter screen 372 filters the impurities in the lubricating oil that have passed through the magnetic suction plate 373. The lubricating oil flows to the bottom of the second housing 371 through the filter screen 372. When the nut needs to be processed, the hydraulic cylinder 31 drives the cover 32 to descend, thereby driving the thread taper 5 to descend to the surface of the nut. The motor 33 drives the thread taper 5 to process the nut. The controller 48 controls the forward and reverse rotation of the motor 33 through the contactor 47. The motor 33 controls the tapping depth and cutting speed of the thread taper 5. At this time, the hydraulic cylinder 31 drives the push rod 45 to leave the push switch 46. The push switch 46 controls the oil injection pump 22 to be energized and to draw lubricating oil. After completion, the hydraulic cylinder 31 drives the cover 32 back to the initial position and drives the push switch 46 to control the oil injection pump 22 to be de-energized.
