Technical Field

[0002] A tapping machine is a device used to create internal threads on metal or non-metal workpieces. It is widely used in machinery manufacturing, mold making, and other fields. During the tapping process, the tap, as the core cutting component, rotates at high speeds and rubs against the workpiece, generating significant heat. Inadequate lubrication can lead to increased tap wear, reduced tapping accuracy, and even tap breakage.

[0003] Currently, traditional tapping machines generally rely on manual, periodic lubrication of the taps by brushing lubricant onto them. This manual lubrication method is not only labor-intensive and difficult to achieve continuous and stable oil supply, but also presents problems such as uneven lubrication and delayed oil supply, which can easily lead to localized overheating of the taps, thus affecting the stability and efficiency of the entire machine.

[0006] By adopting the above technical solution, the transmission oil pump is used to extract lubricating oil from the oil storage assembly and transport it to the annular oil drip assembly through the oil pipeline. The lubricating oil is distributed in the annular oil drip assembly and then flows into multiple rewind oil drip tubes. Under the push of oil pressure, the rewind oil drip tubes gradually stretch out from the curled state and approach the surface of the tapping tap to achieve precise oil supply; after the oil supply is completed, the transmission oil pump stops, the oil pressure is released, and the rewind oil drip tubes rewind to the curled closed state under the action of their own elasticity to prevent oil leakage and foreign matter from entering; the excess lubricating oil dripping to the bottom of the tapping tap is collected by the oil dripping circulation assembly at the bottom of the tapping machine body and returned to the oil storage assembly to achieve the recycling of the lubricating oil; this application realizes fully automatic, quantitative and directional lubrication of tapping taps during the processing process through the cooperation of automatic oil supply, dynamic expansion and contraction and oil recovery, improves lubrication efficiency and consistency, reduces the frequency of manual intervention, extends the service life of the taps, and improves the stability and quality of tapping processing.

The upper inclined oil pipe corresponds to the upper part of the tapping tap, the horizontal oil pipe corresponds to the middle part of the tapping tap, and the lower inclined oil pipe corresponds to the lower part of the tapping tap. Surrounding oil supply is carried out in multiple directions to ensure comprehensive lubrication.

[0010] By adopting the above technical solution, lubricating oil enters the elastic hose from the annular oil drip assembly. Under the push of oil pressure, the elastic hose is straightened and drives the spiral rewinding spring to expand, thereby realizing automatic extension and oil supply to different directions of the tapping tap; after the oil supply is completed, the oil pressure is released, and the spiral rewinding spring drives the elastic hose to rewind to the initial bending or contracted state under its own elastic action, thereby realizing automatic resetting and closing of the oil pipe; the present application provides flexible stretching ability through the elastic hose, and the spiral rewinding spring realizes the driven rewinding function, and completes the automatic extension and rewinding action without the need for additional electronic control or mechanical actuators, which not only improves the adaptability of the oil supply path and the multi-angle lubrication effect, but also simplifies the structural design, improves the reliability and service life of the device, avoids loss or interference caused by long-term exposure, and realizes efficient lubrication of the tapping process.

[0011] Preferably, the annular oil drip assembly includes an oil pipe support frame connected to the tapping machine body, and an annular oil pipe component connected to the end of the oil pipe support frame; the elastic hose is located on the inner side of the annular oil pipe component and is connected to the annular oil pipe component, and the oil pipeline is connected to the oil pipe support frame and is connected to the annular oil pipe component.

Combined with the flexible extension and precise positioning oil supply capability of the elastic hose, the oil drip mechanism of the present application is compactly integrated, ensuring the stability and consistency of the oil supply, while facilitating maintenance and installation, effectively improving the tapping lubrication efficiency and equipment operation reliability.

[0013] Preferably, the oil pipe support frame includes a support frame body, and an oil pipe fixing sleeve connected to the support frame body and used to be sleeved on the outer side wall of the oil pipeline.

The oil pipe fixing sleeve is sleeved on the outer wall of the oil pipeline to achieve stable connection and positioning between the oil pipeline and the support frame body. The support frame body of this application provides high-strength support, effectively ensuring the stable operation of the overall structure of the annular oil drip assembly and the continuity of oil delivery, thereby improving durability, assembly convenience and safety of lubrication system operation.

[0015] Preferably, the oil dripping mechanism further includes a temperature detection component connected to the oil pipe support frame and arranged facing the tapping tap position, the temperature detection component is electrically connected to the transmission oil pump and is used to detect the temperature of the tapping tap surface, when the tapping tap surface temperature is greater than a preset temperature upper limit threshold, the temperature detection component triggers the transmission oil pump to increase the transmission rate to a maximum flow preset value, when the tapping tap surface temperature is less than a preset temperature lower limit threshold, the temperature detection component triggers the transmission oil pump to reduce the transmission rate to a minimum flow preset value.

[0016] By adopting the above technical solution, the temperature detection component is used to monitor the temperature changes on the surface of the tapping tap in real time. The temperature detection component is electrically connected to the transmission oil pump. When the tapping tap generates heat due to high-speed cutting during processing, causing the surface temperature to rise and exceed the preset temperature upper limit threshold, the temperature detection component triggers the transmission oil pump to increase the oil delivery rate to the maximum flow preset value to enhance lubrication and cooling and prevent the tapping tap from overheating and damage; when the temperature of the tapping tap drops and falls below the preset temperature lower limit threshold, the temperature detection component triggers the transmission oil pump again to reduce the oil delivery rate to the minimum flow preset value, thereby saving lubricating oil and avoiding excessive oil supply; this application realizes dynamic matching between the lubricating oil supply amount and the actual working temperature of the tapping tap through closed-loop feedback control between the temperature detection component and the transmission oil pump, which not only responds quickly but also saves energy and reduces consumption, improves the working stability of the tap and extends its service life.

[0019] Preferably, the drip oil recovery circulation assembly further comprises a filter grid inserted into the oil collecting opening, and a filter support ridge connected to the inner wall of the recovery box and used for supporting the filter grid.

[0020] By adopting the above technical solution, when the lubricating oil drips from the tap and enters the recovery box through the oil collecting opening, it is preliminarily filtered through the filter mesh to remove metal chips, dust and other impurities mixed in the lubricating oil. The filter mesh maintains structural strength and accurate position under the stable support of the filter support ridge, preventing displacement or collapse under the impact of the oil flow, thereby ensuring the cleanliness of the recovered oil; the filtered oil falls to the bottom of the recovery box and is transported back to the oil storage assembly by the recovery oil pump through the recovery oil pipe to complete the closed-loop circulation; the present application effectively prevents foreign particles from entering the oil delivery system and causing blockage or pump body wear by setting a filter mesh, and the filter support ridge enhances the mechanical stability and maintenance convenience of the filter mesh, thereby improving the overall operating reliability, service life and oil cleanliness of the lubricating oil circulation system.

[0021] Preferably, the oil drip recovery circulation assembly also includes a first liquid level detection component connected to the inner wall of the recovery box body and located below the filter support protrusion, and a second liquid level detection component connected to the inner wall of the bottom of the recovery box body and located below the first liquid level detection component; the first liquid level detection component and the second liquid level detection component are both electrically connected to the recovery oil pump.

[0022] By adopting the above technical solution, the first liquid level detection component and the second liquid level detection component are both used to dynamically monitor the changes in the oil level in the recovery box. When the lubricating oil drips and accumulates to the height of the first liquid level detection component, the first liquid level detection component triggers the recovery oil pump to start and pumps the lubricating oil back to the oil storage component through the recovery oil pipe. When the oil continues to decrease to below the minimum safe liquid level set by the second liquid level detection component, the second liquid level detection component triggers the recovery oil pump to stop running to prevent dry pumping or damage to the pump body. The present application realizes real-time monitoring of the oil recovery status by setting the first liquid level detection component and the second liquid level detection component at high and low levels, which not only ensures the safety and reliability of the recovery oil pump operation, but also effectively maintains the stability of the system's oil return cycle, and prevents oil supply interruption or equipment failure due to abnormal liquid level.

[0036] The transmission oil pump 35 of the present application is used to extract lubricating oil from the oil storage component 31 and transport it to the annular oil drip component 32 through the oil delivery pipe 34. The lubricating oil is distributed in the annular oil drip component 32 and then flows into multiple rewinding oil dripping tubes 33. Under the push of oil pressure, the rewinding oil dripping tubes 33 gradually stretch out from the curled state and approach the surface of the tapping tap 2 to achieve precise oil supply; after the oil supply is completed, the transmission oil pump 35 stops, the oil pressure is released, and the rewinding oil dripping tubes 33 are rewound to the curled and closed state under the action of their own elasticity to prevent oil leakage and foreign matter from entering; the excess lubricating oil dripping to the bottom of the tapping tap 2 is collected by the oil dripping circulation component 36 at the bottom of the tapping machine body 1 and returned to the oil storage component 31 to achieve the recycling of the lubricating oil; the present application realizes fully automatic, quantitative and directional lubrication of the tapping tap 2 during the processing process through the cooperation of automatic oil supply, dynamic expansion and contraction and oil recovery, thereby improving lubrication efficiency and consistency, reducing the frequency of manual intervention, extending the service life of the tap, and improving the stability and quality of the tapping process.

[0037] Furthermore, if Figure 2 and Figure 3 As shown, the rewinding oil drip pipe 33 includes a horizontal oil pipe 331 connected to the inner side of the annular oil drip assembly 32 and arranged horizontally, an upper inclined oil pipe 332 located on the upper side of the horizontal oil pipe 331 and arranged inclined upward, and a lower inclined oil pipe 333 located on the lower side of the horizontal oil pipe 331 and arranged inclined downward.

[0038] In the present application, when the transmission oil pump 35 is started, the lubricating oil flows synchronously into the horizontal oil pipe 331, the upper inclined oil pipe 332 and the lower inclined oil pipe 333. The upper inclined oil pipe 332 corresponds to the upper part of the tapping tap 2, the horizontal oil pipe 331 corresponds to the middle part of the tapping tap 2, and the lower inclined oil pipe 333 corresponds to the lower part of the tapping tap 2. Circular oil supply is performed in multiple directions to ensure comprehensive lubrication. The present application realizes multi-angle oil supply through a three-section, multi-angle oil pipe configuration, thereby improving the lubrication coverage of the tapping tap 2, and improving the lubrication efficiency and reliability.

[0039] Furthermore, if Figure 3 and Figure 4 As shown, the horizontal oil pipe 331 , the upper inclined oil pipe 332 and the lower inclined oil pipe 333 all include an elastic hose 3311 connected to the annular oil drip assembly 32 , and a spiral rewinding spring 3312 connected to the bottom of the elastic hose 3311 .

[0040] In the present application, the lubricating oil enters the elastic hose 3311 from the annular oil drip assembly 32. Under the push of oil pressure, the elastic hose 3311 is straightened and drives the spiral rewinding spring piece 3312 to expand, thereby realizing automatic extension and oil supply to different directions of the tapping tap 2; after the oil supply is completed, the oil pressure is released, and the spiral rewinding spring piece 3312 drives the elastic hose 3311 to rewind to the initial bending or contracted state under its own elastic action, thereby realizing automatic resetting and closing of the oil pipe; the present application provides flexible stretching ability through the elastic hose 3311, and realizes the driven rewinding function through the spiral rewinding spring piece 3312, and completes the automatic extension and rewinding action without the need for additional electronic control or mechanical actuators, which not only improves the adaptability of the oil supply path and the multi-angle lubrication effect, but also simplifies the structural design, improves the reliability and service life of the device, avoids loss or interference caused by long-term exposure, and realizes efficient lubrication of the tapping process.

[0041] The elastic hose 3311 is preferably a PEEK elastic hose, and the spirally wound spring 3312 is preferably an elastic stainless steel sheet.

[0042] Specifically, if Figure 2 and Figure 3 As shown, the annular oil drip assembly 32 includes an oil pipe support frame 321 connected to the tapping machine body 1, and an annular oil pipe component 322 connected to the end of the oil pipe support frame 321; the elastic hose 3311 is located on the inner side of the annular oil pipe component 322 and is connected to the annular oil pipe component 322, and the oil pipeline 34 is connected to the oil pipe support frame 321 and is connected to the annular oil pipe component 322.

[0043] The oil pipe support frame 321 of the present application is used to support the oil pipeline 34 and the annular oil pipe component 322; the present application achieves stable support for the entire oil supply structure through the oil pipe support frame 321, and achieves uniform distribution and diversion of oil through the annular oil pipe component 322. Combined with the flexible extension and precise positioning oil supply capability of the elastic hose 3311, the oil drip mechanism of the present application is compactly integrated, ensuring the stability and consistency of the oil supply, while facilitating maintenance and installation, effectively improving the tapping lubrication efficiency and equipment operation reliability.

[0044] More specifically, if Figure 2 and Figure 5 As shown, the oil pipe support frame 321 includes a support frame body 3211 and an oil pipe fixing sleeve 3212 connected to the support frame body 3211 and used to be sleeved on the outer wall of the oil pipeline 34.

[0045] The support frame body 3211 of the present application serves as the bearing structure of the entire annular oil drip assembly 32, and is used to install and fix the annular oil pipe component 322 and multiple elastic hoses 3311. The oil pipe fixing sleeve 3212 is sleeved on the outer wall of the oil pipeline 34 to achieve stable connection and positioning between the oil pipeline 34 and the support frame body 3211. The support frame body 3211 of the present application provides high-strength support, effectively ensuring the stable operation of the overall structure of the annular oil drip assembly 32 and the continuity of oil delivery, thereby improving durability, assembly convenience and safety of the lubrication system operation.

[0046] In addition, if Figure 2 and Figure 5 As shown, the oil dripping mechanism 3 also includes a temperature detection component 37 connected to the oil pipe support frame 321 and arranged facing the tapping tap 2. The temperature detection component 37 is electrically connected to the transmission oil pump 35 and is used to detect the temperature of the surface of the tapping tap 2. When the surface temperature of the tapping tap 2 is greater than the preset upper temperature threshold, the temperature detection component 37 triggers the transmission oil pump 35 to increase the transmission rate to the maximum flow preset value. When the surface temperature of the tapping tap 2 is less than the preset lower temperature threshold, the temperature detection component 37 triggers the transmission oil pump 35 to reduce the transmission rate to the minimum flow preset value.

[0047] The temperature detection component 37 of the present application is used to monitor the temperature changes on the surface of the tapping tap 2 in real time. The temperature detection component 37 is electrically connected to the transmission oil pump 35. When the surface temperature of the tapping tap 2 increases due to heat generated by high-speed cutting during processing and exceeds a preset temperature upper limit threshold, the temperature detection component 37 triggers the transmission oil pump 35 to increase the oil delivery rate to a maximum flow preset value to enhance lubrication and cooling and prevent the tapping tap 2 from overheating and damage; when the temperature of the tapping tap 2 decreases and falls below the preset temperature lower limit threshold, the temperature detection component 37 triggers the transmission oil pump 35 again to reduce the oil delivery rate to a minimum flow preset value, thereby saving lubricating oil and avoiding excessive oil supply; the present application realizes dynamic matching between the lubricating oil supply amount and the actual working temperature of the tapping tap 2 through closed-loop feedback control between the temperature detection component 37 and the transmission oil pump 35, which not only responds quickly but also saves energy and reduces consumption, improves the working stability of the tap and extends its service life.

[0048] The temperature detection component 37 is preferably an infrared temperature sensor.

[0049] And, as Figure 5 As shown, the oil dripping recovery circulation assembly 36 includes a recovery box 361 connected to the bottom of the tapping machine body 1 and located below the tapping tap 2, a recovery oil pipe 362 used to connect the recovery box 361 and the oil storage assembly 31, and a recovery oil pump 363 connected to the recovery oil pipe 362. An oil collection opening 364 is provided above the recovery box 361.

[0050] During the processing and lubrication of the tapping tap 2, the excess or splashing lubricating oil drips and flows into the recovery box 361 below through the oil collecting opening 364. The oil is transported to the oil storage assembly 31 along the recovery oil pipe 362 by the recovery oil pump 363, completing the closed-loop recycling of the oil. The present application collects the dripping lubricating oil in a centralized manner through the recovery box 361, improves the oil collection efficiency and coverage through the oil collecting opening 364, and realizes oil return and system closed-loop replenishment through the recovery oil pump 363, effectively avoiding lubricating oil waste and equipment pollution, ensuring a clean working environment, and improving the sustainability and economy of the lubrication system.

[0051] Furthermore, if Figure 5 and Figure 6 As shown, the dripping oil recovery circulation assembly 36 further includes a filter grid 365 inserted into the oil collection opening 364 , and a filter support ridge 366 connected to the inner wall of the recovery box 361 and used to support the filter grid 365 .

[0052] In the present application, when the lubricating oil drips from the tapping tap 2 and enters the recovery box 361 through the oil collecting opening 364, it is preliminarily filtered through the filter mesh 365 to remove metal chips, dust and other impurities contained in the lubricating oil. The filter mesh 365 maintains structural strength and accurate position under the stable support of the filter support ridge 366, preventing displacement or collapse under the impact of the oil flow, thereby ensuring the cleanliness of the recovered oil; the filtered oil falls to the bottom of the recovery box 361, and is transported back to the oil storage component 31 by the recovery oil pump 363 through the recovery oil pipe 362 to complete the closed-loop circulation; the present application effectively prevents foreign particles from entering the oil delivery system and causing blockage or pump body wear by setting the filter mesh 365, and the filter support ridge 366 enhances the mechanical stability and maintenance convenience of the filter mesh 365, thereby improving the overall operating reliability, service life and oil cleanliness of the lubricating oil circulation system.

[0053] Furthermore, if Figure 2 and Figure 6 As shown, the oil drip recovery circulation component 36 also includes a first liquid level detection component 367 connected to the inner wall of the recovery box 361 and located below the filter support protrusion 366, and a second liquid level detection component 368 connected to the inner wall of the bottom of the recovery box 361 and located below the first liquid level detection component 367; the first liquid level detection component 367 and the second liquid level detection component 368 are both electrically connected to the recovery oil pump 363.

[0054] The first liquid level detection component 367 and the second liquid level detection component 368 of the present application are both used to dynamically monitor the changes in the oil level in the recovery box 361. When the lubricating oil drips and accumulates to the height of the first liquid level detection component 367, the first liquid level detection component 367 triggers the recovery oil pump 363 to start, and pumps the lubricating oil back to the oil storage component 31 through the recovery oil pipe 362. When the oil continues to decrease to below the minimum safe liquid level set by the second liquid level detection component 368, the second liquid level detection component 368 triggers the recovery oil pump 363 to stop running to prevent dry pumping or damage to the pump body; the present application realizes real-time monitoring of the oil recovery status by setting the first liquid level detection component 367 and the second liquid level detection component 368 at different heights, which not only ensures the safety and reliability of the operation of the recovery oil pump 363, but also effectively maintains the stability of the system's oil return cycle, and prevents oil supply interruption or equipment failure due to abnormal liquid level.

[0055] Both the first liquid level detection component 367 and the second liquid level detection component 368 are preferably liquid level sensors.

Under the hydraulic pressure, the rewinding oil drip pipe 33 stretches to a straightened oil supply state close to the tapping tap 2. S3: Multiple rewinding oil dripping pipes 33 on the side of the tapping tap 2 supply oil to the tapping tap 2; S4: When the transmission oil pump 35 stops, the oil pressure in the rewinding oil dripping pipe 33 is released, and the rewinding oil dripping pipe 33 is rewound and bent to form a curled and closed state to prevent oil leakage or air from entering.

[0057] The transmission oil pump 35 of the present application transports the lubricating oil in the oil storage assembly 31 to the annular oil drip assembly 32 through the oil delivery pipe 34, and the lubricating oil flows from the annular oil drip assembly 32 into multiple rewinding oil dripping pipes 33. Under the action of oil pressure, the rewinding oil dripping pipe 33 extends from the initial curled and closed state to the straightened oil supply state close to the tapping tap 2. The multiple rewinding oil dripping pipes 33 synchronously supply oil to the circumference of the tapping tap 2 in a targeted manner, ensuring sufficient lubrication and effective heat dissipation during the processing; when the transmission oil pump 35 stops, the oil pressure is released, and the rewinding oil dripping pipe 33 rewinds and bends to form a curled and closed state, effectively preventing residual oil from dripping or external air and impurities from entering; the present application realizes automatic supply of lubricating oil and dynamic expansion and contraction control of the pipeline through the combination of hydraulic control and elastic structure. The present application has strong adaptability, sensitive response, comprehensive lubrication coverage, fuel saving and environmental protection, improves tapping efficiency, extends the life of the tapping tap 2 and reduces the frequency of equipment maintenance.

[0058] The implementation principle of the oil dripping device and oil dripping method of the tapping machine in the embodiment of the present application is as follows: An oil dripping device for a tapping machine, wherein a transmission oil pump 35 is used to extract lubricating oil from an oil storage assembly 31 and deliver it to an annular oil dripping assembly 32 through an oil delivery pipe 34. The lubricating oil is distributed in the annular oil dripping assembly 32 and then flows into a plurality of rewinding oil dripping pipes 33. Under the push of oil pressure, the rewinding oil dripping pipes 33 gradually stretch out from a curled state and approach the surface of the tap 2 to achieve precise oil supply. After the oil supply is completed, the transmission oil pump 35 stops, the oil pressure is released, and the rewinding oil dripping pipes 33 rewind to a curled closed state under the action of their own elasticity. The lubricating oil dripping to the bottom of the tapping tap 2 is collected by the oil recovery and circulation component 36 at the bottom of the tapping machine body 1 and returned to the oil storage component 31 to realize the recycling of the lubricating oil. The present application realizes the fully automatic, quantitative and directional lubrication of the tapping tap 2 during the processing process through the combination of automatic oil supply, dynamic expansion and contraction and oil recovery, thereby improving the lubrication efficiency and consistency, reducing the frequency of manual intervention, extending the service life of the tap, and improving the stability and quality of the tapping process. When the transmission oil pump 35 is activated, lubricating oil flows synchronously into the horizontal oil pipe 331, the upper inclined oil pipe 332 and the lower inclined oil pipe 333. The upper inclined oil pipe 332 corresponds to the upper part of the tapping tap 2, the horizontal oil pipe 331 corresponds to the middle part of the tapping tap 2, and the lower inclined oil pipe 333 corresponds to the lower part of the tapping tap 2. Circular oil supply is carried out in multiple directions to ensure comprehensive lubrication. The present application realizes multi-angle oil supply through a three-section, multi-angle oil pipe configuration, thereby improving the lubrication coverage of the tapping tap 2, and enhancing lubrication efficiency and reliability. The oil pump 35 is used to transfer the lubricating oil in the oil storage assembly 31 to the annular oil drip assembly 32 through the oil delivery pipe 34. The lubricating oil flows from the annular oil drip assembly 32 into a plurality of rewinding oil dripping pipes 33. Under the action of oil pressure, the rewinding oil dripping pipe 33 stretches from an initial curled and closed state to a straightened oil supply state close to the tapping tap 2. The plurality of rewinding oil dripping pipes 33 synchronously carry out directional oil supply to the circumference of the tapping tap 2, ensuring sufficient lubrication and effective heat dissipation during the machining process; when the oil pump 35 stops, the oil pressure is released, and the rewinding oil dripping pipe 33 rewinds and bends to form a curled and closed state, effectively preventing residual oil from leaking or external air and impurities from entering; the present application realizes automatic supply of lubricating oil and dynamic expansion and contraction control of the pipeline through the cooperation of hydraulic control and elastic structure. The present application has strong adaptability, sensitive response, comprehensive lubrication coverage, fuel saving and environmental protection, improves tapping efficiency, extends the life of the tapping tap 2 and reduces the frequency of equipment maintenance.

[0059] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
