Abstract
Description
Technical Field
[0001] This invention relates to the field of waste cleaning technology, specifically a device for removing debris from wrench blanks during machining. Background Technology
[0002] During the machining process, wrench blanks generate a large amount of metal shavings. If not cleaned in time, these shavings can easily adhere to the workpiece surface, fixtures, and equipment gaps, affecting machining accuracy and potentially scratching the blank, accelerating tool wear, and reducing production efficiency and product qualification rate. Therefore, a specialized shavings removal device is needed to achieve rapid separation and cleaning of shavings during machining, ensuring machining quality and normal equipment operation.
[0003] For example, Chinese Patent CN217491780U discloses a wrench mold with an automatic impurity removal function, including a lower wrench mold and an upper wrench mold that is mounted on the lower wrench mold. The lower wrench mold has a slot horizontally provided on it, and a cleaning mechanism is provided on it. The cleaning mechanism includes an insert plate, which is fitted with a sliding member, a fixing member, and a cleaning member. The sliding member is installed in the slot. When the upper wrench mold moves upward, the two cleaning members can reciprocate horizontally between the lower wrench mold and the upper wrench mold through the horizontal reciprocating motion of the sliding member.
[0004] However, the above technical solutions still have some problems. Whether it is a ratchet wrench or an adjustable wrench, in order to facilitate the installation of the ratchet locking mechanism and the adjustable mechanism, a through hole or a blind hole will be provided on the wrench. The cleaning of the through hole is relatively simple, but the cleaning of the blind hole will have the following problems. First, cutting fluid, rust-preventive oil, lubricating oil and other cleaning oils are used in the manufacturing process of the wrench. During the tapping process, waste chips will remain in the blind hole, which will cause the waste chips to combine with oily substances and adhere to the blind hole. If water is used for rinsing, air resistance will be formed in the blind hole, making it difficult for the liquid to contact the waste chips and oily substances, thus making it difficult to complete the cleaning of the blind hole and causing the subsequent wrench assembly to fail.
[0005] Therefore, how to clean the blind holes of wrenches is a problem that needs to be solved. Summary of the Invention
[0006] This invention provides a device for removing debris from wrench blanks during machining, in order to solve the aforementioned problems existing in the prior art.

[0025] The adapter pipe is the discharge end of the cleaning component; the mounting knob is connected to the air supply section.
[0026] Furthermore, the gas injection chamber is also provided with an adjustment seat, which is H-shaped and divides the gas injection chamber into two parts. The part near the liquid injection chamber is provided with a first spring, and the other part is provided with a second spring.
[0027] The first spring is connected to the adjusting seat and the connecting seat respectively, and the second spring is connected to the adjusting seat and the mounting knob respectively;
[0028] The adjusting seat is provided with an oblique hole for connecting the liquid injection chamber and the transfer pipe, and the adjusting seat is also provided with a gas delivery groove in the circumferential direction for connecting the gas injection chamber and the transfer pipe.
[0029] By operating the drive switch, the position of the adjusting seat is changed, causing one end of the inclined hole to abut against the inner wall of the connecting seat, blocking the inclined hole and reducing liquid injection.

[0031] The drive rod is a variable diameter rod. The position of the drive rod is changed by adjusting the cylinder, so that the free end of the drive rod moves toward the adjusting cylinder, so that a flow area is created between the drive rod and the inner wall of the limiting seat, allowing the liquid to pass through the limiting seat.
[0032] The adjusting seat is sleeved on the driving rod, and the part of the limiting seat that extends into the area where the first spring is located is the protruding end. The protruding end is provided with multiple water outlet holes in the circumferential direction.

[0040] Beneficial Effects: This invention discloses a device for removing machining debris from wrench blanks. To clean the blind holes of the wrench, the device includes a drive unit. The drive unit rotates the transport unit, which in turn rotates the transport rod via a transmission seat. During this process, the lifting unit moves, positioning the transport rod within the blind hole. As the transport rod extends, impurities adhering to the inner wall of the blind hole are squeezed into the transport groove. Then, the cleaning component begins operation, using gas injection to push the impurities into the transport groove. The movement of the cylinder completes the cleaning of impurities in the blind holes. Simultaneously, the movement of the drive unit breaks the adhesion between the impurities and the blind holes, facilitating subsequent airflow and water cleaning. This prevents air resistance caused by the structure of the blind holes during water purging. After the purging process is completed, the volume of the transition chamber is changed by adjusting the cylinder, thereby pressurizing the gas in the transition chamber. This not only blocks the water flow but also blows air into the blind holes, allowing the water droplets remaining in the blind holes to be discharged, thus completing the cleaning of the blind holes.

Detailed Implementation
[0052] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0053] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.
[0054] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.
[0055] This invention discloses a device for removing debris from the machining of wrench blanks, with reference to... Figures 1-10 ,include:
[0056] The system includes a testing platform 1, a feeding mechanism 2 mounted on the testing platform 1, and a limiting mechanism 3 located on the feeding mechanism 2; a blowing and cleaning unit 4 connected to the testing platform 1, used to remove and clean oil and debris from the blind holes of the wrench; the blowing and cleaning unit 4 includes a lifting part fixedly mounted on the testing platform 1, a transport component 45 connected to the lifting part, and a cleaning component 46 mounted on the transport component 45; the transport component 45 extends into the blind hole under the drive of the lifting part, and the cleaning component 46 is used to deliver gas or liquid or a mixture of both into the transport component 45, and cooperates with the transport component 45 to allow the oil and debris adhering to the blind hole to be discharged from the blind hole along a predetermined area on the transport component 45, thereby cleaning the blind holes on the wrench;
[0057] By extending the transport rod 458, impurities adhering to the inner wall of the blind hole can be squeezed into the transport groove 4514. Then, the cleaning component 46 starts to work, and by spraying gas, it can push the impurities to move in the transport groove 4514, thus completing the cleaning of impurities in the blind hole. At the same time, the movement of the drive unit can break the adhesion between the impurities and the blind hole, so that the blind hole can be cleaned during subsequent airflow and water flow cleaning, and avoid air resistance caused by the structure of the blind hole when the water flow is blown.
[0058] By extending the transport component 45 into the blind hole, the oil and debris on the inner wall are pre-squeezed into the transport groove 4514, avoiding the air resistance and liquid lock problems caused by the closed structure of the blind hole during traditional air blowing and rinsing, ensuring that the air and water flow can smoothly act on the bottom of the hole; the transport groove 4514 forms a directional slag discharge path, so that the oil and debris are discharged in an orderly manner along the preset area, without accumulating, getting stuck or re-adhering in the blind hole, resulting in a more thorough cleaning; through the synergistic effect of mechanical intervention and air-liquid flushing, the adhesion between the oil and debris and the inner wall of the blind hole is first broken, and then the air or liquid flow is used to push them out, which greatly improves the cleaning effect on stubborn impurities and solves the pain points of traditional cleaning methods that cannot be flushed, blown out or cleaned properly.
[0059] The lifting unit includes a lifting cylinder 41 and a slide rail 44 fixedly installed on the testing table 1, a slide plate 43 connected to the output end of the lifting cylinder 41, and a slider 42 fixedly installed on the slide plate 43 and slidably connected to the slide rail 44; the transport component 45 is fixedly installed on the slide plate 43.
[0060] When it is necessary to position the transport component 45 in the blind hole, the lifting cylinder 41 starts to work. The moving lifting cylinder 41 can drive the slide plate 43 to move. At this time, the slide plate 43 can move on the slide rail 44 with the cooperation of the slider 42, thereby adjusting the height of the transport component 45 so that the transport rod 458 can be inserted into the blind hole, completing the adjustment of the position of the transport rod 458.
[0061] The transport assembly 45 includes a lifting seat 451 connected to the slide plate 43, a drive unit fixedly mounted on the lifting seat 451, a transport unit 459 connected to the drive unit, and a transport rod 458 disposed on the transport unit 459; the transport rod 458 is provided with a plurality of spiral transport grooves 4514 in the circumferential direction, and an exhaust channel 4513 disposed in the axial direction of the transport rod 458; the drive unit includes a rotary motor 452 fixedly mounted on the lifting seat 451, a drive gear 453 connected to the output end of the rotary motor 452, a transmission shaft 455 movably disposed in the lifting seat 451, a first bevel gear 456 and a transmission gear 454 sleeved on the transmission shaft 455, and a second bevel gear 457 meshing with the first bevel gear 456 and disposed in the lifting seat 451; the transmission gear 454 meshes with the drive gear 453; a certain gap is reserved between the outer wall of the transport rod 458 and the inner wall of the blind hole.
[0062] Through the reserved gaps, the oil and debris on the inner wall of the blind hole will be directly squeezed and scraped by the transport rod 458 and forced into the space of the groove;
[0063] When the transport rod 458 is in the blind hole, the rotary motor 452 starts to work. The rotating rotary motor 452 drives the drive gear 453 to rotate, and then the rotating drive gear 453 drives the transmission gear 454 to rotate. In turn, the rotating transmission gear 454 drives the transmission shaft 455 to rotate, and then the rotating transmission shaft 455 drives the first bevel gear 456 to rotate. Then, the rotating first bevel gear 456 drives the second bevel gear 457 to rotate, thereby completing the driving work of the transport unit 459 and enabling the transport rod 458 to rotate.
[0064] By rotating the transport rod 458, the groove edges of the transport rod 458 scrape and shear the oil and debris on the inner wall of the blind hole, removing the oil particles and turning the oil from a firmly attached state into a loose, suspended state, greatly reducing the difficulty of subsequent cleaning. During the rotation, the spiral or helical grooves act like an auger, actively drawing in and transporting the debris and oil inside the hole into the groove, forming a continuous slag discharge channel. This prevents impurities from randomly accumulating inside the hole, ensuring that impurities can be smoothly discharged along the groove during subsequent gas-liquid flushing, instead of being pushed back into the dead corner at the bottom of the hole. Furthermore, the rotation breaks the closed state inside the blind hole, allowing the gas-liquid medium to more easily enter the bottom of the hole, while simultaneously agitating the internal liquid and air, disrupting the conditions for the formation of gas resistance or liquid lock. This ensures that the subsequent gas-liquid flushing can truly act on the bottom of the hole, rather than just circling around the opening. Finally, the rotation ensures 360° contact between the rod and the inner wall of the blind hole, avoiding the problem of one side not being cleaned when extending straight in, ensuring that the entire inner wall of the blind hole can be effectively cleaned.
[0065] The transport unit 459 includes a connecting rod 4510 disposed in the lifting seat 451 and connected to the second bevel gear 457, an air supply passage 4515 disposed in the connecting rod 4510, and a transmission seat 4512 disposed between the connecting rod 4510 and the transport rod 458 for limiting and fixing the transport rod 458; the transmission seat 4512 is provided with a transmission channel for connecting the air supply passage 4515 and the exhaust passage 4513;
[0066] When the oil and debris are in the transport groove 4514, the air pump can supply air to the lifting seat 451 through the cleaning component 46. At this time, the gas can contact the bottom of the blind hole through the gap 4511, the air supply channel 4515, the transmission channel and the exhaust channel 4513, thereby pushing the oil and debris to move in the transport groove 4514, thus completing the removal of oil and debris.
[0067] The gas is directly delivered to the bottom of the blind hole through the gap 4511, the gas supply channel 4515, the transmission channel and the exhaust channel 4513. This can form a stable and directional thrust on the oil and debris in the transport groove 4514, so that the oil and debris are discharged outward in an orderly manner along the transport groove 4514, achieving efficient cleaning of impurities inside the blind hole. At the same time, it can prevent the gas from swirling at the opening of the blind hole, ensuring the smooth progress of the cleaning work.
[0068] The air supply channel 4515 includes two parts, one part being a cross-shaped channel and the other part being a straight channel, wherein one free end of the straight channel is connected to the intersection of the cross-shaped channel; the connecting rod 4510 is I-shaped, and a gap 4511 is reserved between the middle end of the connecting rod 4510 and the lifting seat 451, and the gap 4511 is connected to the cross-shaped channel; the cleaning component 46 is sleeved on the lifting seat 451, and the discharge end of the cleaning component 46 is connected to the gap 4511.
[0069] The cleaning assembly 46 includes an adapter pipe 461 sleeved on the lifting base 451, a connecting seat 462 connected to the adapter pipe 461, an injection chamber 463 and an air injection chamber 464 formed in the connecting seat 462, a drive switch 468 located in the injection chamber 463, an air supply section 469 located in the air injection chamber 464, and an installation knob screwed to the connecting seat 462; one end of the drive switch 468 passes through the injection chamber 463 and extends into the air injection chamber 464 and is connected to the air supply section 469, serving as the power source for the air supply section 469; the adapter pipe 461 is the discharge end of the cleaning assembly 46; the installation knob is connected to the air supply section 469;
[0070] During normal operation, the gas and liquid can mix to clean the blind hole. After cleaning, there is no need to change the gas output pressure. By driving the switch 468 to shut off the liquid delivery process, the volume of the transition chamber 4693 can also be changed, and the transition chamber 4693 can be squeezed to increase the gas pressure. This allows the gas to blow out the residual droplets in the blind hole, preventing a large number of droplets from remaining in the blind hole.
[0071] The air injection chamber 464 is also provided with an adjusting seat 465, which is H-shaped. The adjusting seat 465 divides the air injection chamber 464 into two parts. The part near the liquid injection chamber 463 is provided with a first spring 466, and the other part is provided with a second spring 467. The first spring 466 is connected to the adjusting seat 465 and the connecting seat 462 respectively, and the second spring 467 is connected to the adjusting seat 465 and the mounting knob respectively. The adjusting seat 465 is provided with an oblique hole for connecting the liquid injection chamber 463 and the adapter pipe 461. The adjusting seat 465 is also provided with an air delivery groove 4698 on its circumference for connecting the air injection chamber 464 and the adapter pipe 461. By driving the operation of the drive switch 468, the position of the adjusting seat 465 is changed, so that one end of the oblique hole abuts against the inner wall of the connecting seat 462, blocking the oblique hole and reducing liquid injection.
[0072] After the cleaning work is completed, the regulating cylinder 4681 starts to work, which in turn drives the regulating seat 465 to move, so that the drain end of the inclined hole abuts against the inner wall of the connecting seat 462, stopping the liquid from entering and ensuring the smooth progress of the airflow purging work.
[0073] The drive switch 468 includes a water inlet 4684 disposed on the connecting seat 462 for connecting the water inlet 4684 with the injection channel of the injection chamber 463, an adjusting cylinder 4681 located in the injection chamber 463, a drive rod 4682 connected to the output end of the adjusting cylinder 4681, and a limiting seat 4683 disposed in the injection chamber 463; the drive rod 4682 is a variable diameter rod, and the position of the drive rod 4682 is changed by adjusting the cylinder 4681, so that the free end of the drive rod 4682 moves toward the adjusting cylinder 4681, so that a flow area appears between the drive rod 4682 and the inner wall of the limiting seat 4683, thereby allowing liquid to pass through the limiting seat 4683; the adjusting seat 465 is sleeved on the drive rod 4682, and the part of the limiting seat 4683 that extends into the area where the first spring 466 is located is the protruding end, and the protruding end is provided with multiple water outlet holes in the circumferential direction.
[0074] When performing intravenous infusion, the regulating cylinder 4681 starts to work. The moving regulating cylinder 4681 can drive the drive rod 4682 to move, thereby adjusting the position of the drive rod 4682. Through the flow area between the drive rod 4682 and the limiting seat 4683, the liquid can pass through the limiting seat 4683 and through the water outlet to the area where the first spring 466 is located. Then, along the connecting hole 4686 on the regulating seat 465, the liquid can be transported to the connecting seat 462, and then along the connecting pipe 461 into the gap 4511, so that it can be discharged from the exhaust port 4513 along with the gas.
[0075] Liquids can be transported and mixed with gases simultaneously and discharged, forming a gas-liquid synergistic cleaning mode. During the discharge process, the gas-liquid mixed medium generates a pulse flushing effect, which can soften and peel off the oil and debris attached to the inner wall of the blind hole by means of the wetting and dissolving properties of the liquid, and can also use the impact force of the gas to push the impurities away from the hole wall quickly. The synergistic effect of the two significantly improves the cleaning ability of oil and stubborn impurities, making the cleaning of the inside of the blind hole more thorough and effectively improving the cleanliness and cleaning quality of the blind hole.
[0076] The air supply unit 469 includes an air inlet seat 4691 connected to the mounting knob, a placement groove formed in the air inlet seat 4691, a baffle plate 4694 located in the placement groove, a return spring 4696 connected to the baffle plate 4694, a valve needle 4695 connected to the return spring 4696 and located in the placement groove, and an air inlet nozzle detachably mounted on the air inlet seat 4691; one end of the air inlet nozzle extends out of the connecting seat 462, and the second spring 467 is located between the adjusting seat 465 and the air inlet seat 4691; an exhaust area 4697 communicating with the air supply groove 4698 is reserved between the outer wall of the air inlet seat 4691 and the inner wall of the adjusting seat 465; the air inlet seat 4691 is also provided with an exhaust area 4697 communicating with the exhaust area 4697. Vent hole 4699; the baffle plate 4694 is provided with a through hole; the baffle plate 4694 divides the placement slot into two areas, one of which is a first placement area and the other is a second placement area, wherein one end of the drive rod 4682 extends into the first placement area, and the valve needle 4695 is located in the second placement area, and a transition cavity 4693 is provided between the drive rod 4682 and the valve needle 4695; the drive rod 4682 is provided with two interconnected air intake grooves 4692, one of which is located circumferentially on the drive rod 4682 and is spiral, and the other is along the axial direction of the drive rod 4682 and can communicate with the air inlet; the volume of the transition cavity 4693 changes with the movement of the drive rod 4682;
[0077] During the exhaust process, the air pump delivers air to the air intake groove 4692 through the air inlet. The gas then flows through the air intake groove 4692 into the transition chamber 4693. As the gas injection volume increases, the valve needle 4695 overcomes the elastic force generated by the return spring 4696, allowing the gas to enter the exhaust area 4697 and exit from the air delivery groove 4698. The gas then mixes with the liquid in the connecting seat 462, completing the cleaning of the inner wall of the blind hole. After the cleaning is completed, the operation of the adjusting cylinder 4681 causes the drive rod 4682 to move in the placement groove. At this time, the air intake groove 4692 and the air inlet are misaligned, and the volume of the transition chamber 4693 gradually decreases, thereby pressurizing the gas in the transition chamber 4693. The pressurized gas is then discharged from the transport rod 458, which blows away any remaining droplets in the blind hole, reducing the amount of droplets remaining.
[0078] This structure effectively solves the problems of traditional blind hole cleaning devices, which have limited functionality and require separate cleaning and drying processes, thus avoiding inefficiency caused by multiple process switching. Automatic gas pressurization is achieved through volume changes in the transition chamber 4693, solving the problem of insufficient pressure from ordinary airflow in removing residual liquid droplets deep within blind holes. This reduces liquid residue in blind holes and lowers the risk of corrosion and secondary contamination. Simultaneously, the stable gas-liquid mixture output improves the incomplete removal of oil stains and stubborn debris by traditional cleaning methods, enhancing the cleaning quality and reliability of the blind hole's inner wall.
[0079] Working principle description: When the transport component 45 needs to be positioned in the blind hole, the lifting cylinder 41 starts working. The moving lifting cylinder 41 drives the slide plate 43 to move. At this time, the slide plate 43 can move on the slide rail 44 with the cooperation of the slider 42, thereby adjusting the height of the transport component 45 so that the transport rod 458 can extend into the blind hole, completing the adjustment of the position of the transport rod 458. After the transport rod 458 is positioned in the blind hole, the rotary motor 452 starts working. The moving rotary motor 452 drives the drive gear 453 to rotate, then the moving drive gear 453 drives the transmission gear 454 to rotate, then the moving transmission gear 454 drives the transmission shaft 455 to rotate, then the moving transmission shaft 455 drives the first bevel gear 456 to rotate, then the moving first bevel gear 456 drives the second bevel gear 457 to rotate, thereby completing the driving work of the transport part 459, so that the transport rod 458 can rotate.
[0080] When the oil and debris are in the transport groove 4514, the air pump can supply air to the lifting seat 451 through the cleaning component 46. At this time, the gas can contact the bottom of the blind hole through the gap 4511, the air supply channel 4515, the transmission channel and the exhaust channel 4513, thereby pushing the oil and debris to move in the transport groove 4514, thus completing the removal of oil and debris.
[0081] During the infusion process, the regulating cylinder 4681 starts working, driving the drive rod 4682 to move and adjust its position. Through the flow area between the drive rod 4682 and the limiting seat 4683, the liquid passes through the limiting seat 4683 and the outlet hole to the area where the first spring 466 is located. Then, along the connecting hole 4686 on the regulating seat 465, the liquid is transported to the connecting seat 462, and then along the connecting pipe 461 into the gap 4511, where it is discharged from the exhaust passage 4513 with the gas. After the cleaning process is completed, the regulating cylinder 4681 starts working again, moving the regulating seat 465 so that the drain end of the inclined hole abuts against the inner wall of the connecting seat 462, stopping the liquid from entering and ensuring the smooth operation of the airflow purging process.
[0082] During the exhaust process, the air pump delivers air to the air intake groove 4692 through the air inlet. The gas then flows through the air intake groove 4692 into the transition chamber 4693. As the gas injection volume increases, the valve needle 4695 overcomes the elastic force generated by the return spring 4696, allowing the gas to enter the exhaust area 4697 and exit from the air delivery groove 4698. The gas then mixes with the liquid in the connecting seat 462, completing the cleaning of the inner wall of the blind hole. After the cleaning is completed, the operation of the adjusting cylinder 4681 causes the drive rod 4682 to move in the placement groove. At this time, the air intake groove 4692 and the air inlet are misaligned, and the volume of the transition chamber 4693 gradually decreases, thereby pressurizing the gas in the transition chamber 4693. The pressurized gas is then discharged from the transport rod 458, which blows away any remaining droplets in the blind hole, reducing the amount of droplets remaining.
