Description

Technical Field

[0001] The present application relates to the technical field of oil filtration, and particularly to an oil filtration system for a riveting machine. Background Art

[0002] A riveting machine is a new type of riveting equipment developed based on the principle of cold rolling. During the use of the riveting machine, in order to reuse the oil, a centrifugal oil filter is often used to filter the oil, so as to separate the oil sludge and oil in the oil.

[0003] Common centrifugal oil filters include a bracket and a fuel tank fixedly welded to the bracket for temporarily storing the filtered clean oil. The upper side of the fuel tank is open and is detachably provided with a tank cover. A drum is rotatably installed in the fuel tank in a sealed manner. A rotating motor for driving the drum to rotate along the axis of the drum is also provided on the bracket. The tank cover is provided with an opening and is connected with an oil inlet pipe. One end of the oil inlet pipe is inserted into the drum. A liquid skimming pipe connecting the fuel tank and the inside of the drum is provided on the tank cover. After the contaminated oil enters the drum from the opening of the tank cover, the drum rotates at a high speed. The impurities in the oil are subjected to high-speed centrifugal force and adhere to the inner peripheral wall of the drum to form an oil sludge layer. The upper side of the drum is provided with a reduced opening, which can reduce the oil from spilling to the outside of the drum when the drum rotates. The oil in the drum away from the inner peripheral wall of the drum flows out through the liquid skimming pipe and enters between the outer peripheral wall of the drum and the inner peripheral wall of the fuel tank. An oil outlet is opened on the outer side wall of the fuel tank close to the bottom wall, and an oil outlet pipe is connected to the fuel tank at the oil outlet. The filtered clean oil is discharged through the liquid outlet pipe, which is convenient for reusing the oil.

[0004] Regarding the above related technology, the inventor believes that during the rotation of the drum, the oil in the drum will be centrifuged. After being subjected to the centrifugal force, the impurities in the oil will adhere to the inner peripheral wall of the drum to form oil sludge, and the thickness of the oil sludge gradually increases with time. The increase in the thickness of the oil sludge reduces the efficiency of the impurities in the oil adhering to the inner peripheral wall of the drum, and reduces the separation efficiency of the impurities in the oil. When cleaning the oil sludge, it is necessary to close the centrifugal oil filter and open the tank cover at the same time, and then the operator reaches into the drum to clean it. Moreover, the upper end of the drum is provided with a reduced opening, which is inconvenient for the operator to clean the oil sludge. Summary of the Invention

[0005] In order to improve the problem that it is inconvenient to clean the oil sludge, the present application provides an oil filtration system for a riveting machine.

[0006] An oil filtration system for a riveting machine provided by the present application adopts the following technical solution:

[0007] An oil filtering system for a riveting machine, comprising a bracket, an oil tank with an upper opening fixedly arranged on the bracket, a rotating drum rotatably installed in the oil tank, a rotating motor for driving the rotating drum to rotate, and a tank cover detachably installed on the oil tank. One side of the inner side of the tank cover is fixedly provided with a guide rod. One end of the guide rod is located inside the rotating drum, and the guide rod is parallel to the axis of the rotating drum. A receiving box is slidably installed in the rotating drum along the guide rod. A slag scraping mechanism for scraping off sludge on the inner peripheral wall of the rotating drum is further arranged on the receiving box. A slag receiving port is formed on one side of the receiving box. When the slag scraping mechanism slides synchronously along the length of the guide rod with the receiving box, part of the slag scraping mechanism abuts against the inner peripheral wall of the rotating drum. When the rotating drum rotates, the slag scraping mechanism can scrape off the sludge on the inner peripheral wall of the rotating drum and send it into the slag receiving port.

[0008] By adopting the above technical solution, after part of the slag scraping mechanism abuts against the inner peripheral wall of the rotating drum, when the rotating drum rotates, the slag scraping mechanism can scrape off the sludge at the abutting position between the inner peripheral wall of the rotating drum and the slag scraping mechanism. At the same time, the sludge scraped off from the inner peripheral wall of the rotating drum enters the receiving box through the slag receiving port, and the scraped sludge can be stored. At the same time, the slag scraping mechanism slides along the guide rod with the receiving box. When the rotating drum rotates, the slag scraping mechanism can fully scrape off the sludge on the inner peripheral wall of the rotating drum, and the slag scraping mechanism can reciprocally scrape the sludge on the inner peripheral wall of the rotating drum, improving the cleaning effect of the sludge on the inner peripheral wall of the rotating drum. When cleaning the sludge on the inner peripheral wall of the rotating drum, there is no need to open the tank cover, which is convenient for cleaning the sludge on the inner peripheral wall of the rotating drum, and the receiving box can store the sludge, improving the problem that it is inconvenient to clean the sludge.

[0009] Optionally, the slag scraping mechanism includes a slag scraping seat rotatably connected in the receiving box, a push-pull assembly for driving the slag scraping seat to rotate along its rotation axis. The slag scraping seat passes through the slag receiving port movably. A slag guiding groove for the sludge to pass through is formed on the slag scraping seat. The slag scraping seat is movably abutted against the inner peripheral wall of the rotating drum. When the side of the slag scraping seat away from the receiving box abuts against the inner wall of the rotating drum, the slag guiding groove is located inside the slag receiving port, and one end of the slag guiding groove faces the abutting position between the rotating drum and the slag scraping seat.

[0010] By adopting the above technical solution, controlling the push-pull assembly to push the slag scraping seat to rotate can extend part of the slag scraping seat out of the receiving box through the slag receiving port, enabling the slag scraping seat to abut against the receiving box. The slag scraping seat can scrape the inner peripheral wall of the rotating drum, and the slag guiding groove can guide the sludge scraped by the slag scraping seat, facilitating the sludge scraped by the slag scraping seat to be sent into the receiving box.

[0011] Optionally, the push-pull assembly includes a rotating seat rotatably mounted in the receiving box, a rotating rod for driving the rotating seat to rotate along its rotation axis, a first transmission rod, and a second transmission rod. One end of the first transmission rod is integrally and fixedly connected to the rotating seat, and the other end is rotatably connected to the second transmission rod. The end of the second transmission rod away from the first transmission rod is rotatably connected to the slag scraping seat. The rotation axes at both ends of the second transmission rod and the rotation axis of the rotating seat are all parallel to the rotation axis of the slag scraping seat.

[0012] By adopting the above technical solution, when controlling the rotating rod to drive the rotating seat to rotate along its rotation axis, the first transmission rod can be made to approach the slag scraping seat. The first transmission rod and the second transmission rod cooperate with each other to drive the slag scraping seat to rotate along its rotation axis and move away from the rotating seat, so that the slag scraping seat abuts against the inner peripheral wall of the rotating drum; when the rotating seat is rotated in the reverse direction, the slag scraping seat can be driven to rotate and approach the rotating seat, which is convenient for receiving the slag scraping seat into the receiving box.

[0013] Optionally, a threaded hole is formed through the rotating seat along its rotation axis. The rotating rod is a threaded rod threadedly adapted to the threaded hole, and the threaded rod is connected to the rotating seat by a lead screw. An activity hole for the threaded rod to pass through is hermetically formed on the receiving box. The rotating rod is parallel to the guiding rod. The end of the threaded rod away from the rotating drum passes through and is rotatably connected to the box cover, and a rotating member for driving the threaded rod to rotate along its axis is fixedly provided on the box cover.

[0014] By adopting the above technical solution, controlling the rotating member can more conveniently drive the threaded rod to drive the rotating seat to rotate. The structure is relatively simple and the operation is relatively convenient.

[0015] Optionally, a limiting block is fixedly provided on the rotating seat, and a positioning seat for limiting the rotation angle of the rotating seat is fixedly provided on the receiving box. When the limiting block abuts against the positioning seat, the slag scraping seat abuts against the inner peripheral wall of the rotating drum.

[0016] By adopting the above technical solution, when the threaded rod drives the rotating seat to rotate and controls the rotating seat to drive the slag scraping seat to extend out of the receiving box and abut against the inner peripheral wall of the rotating drum, the limiting block abuts against the positioning seat, which can limit the rotation of the rotating seat; continuing to control the threaded rod to continue rotating in the same direction, relative rotation can occur between the rotating seat and the threaded rod, so that the rotating seat drives the receiving box to slide along the guiding rod. When the rotating drum rotates, the slag scraping seat can effectively scrape and clean the inner peripheral wall of the rotating drum.

[0017] Optionally, a limiting seat for limiting the rotation angle of the rotating seat is fixedly provided on the receiving box. When the limiting block abuts against the limiting seat, the slag scraping seat rotates and extends into the receiving box.

[0018] By adopting the above technical solution, controlling the reverse rotation of the threaded rod can make the swivel base rotate in the reverse direction, and the slag scraping seat can be retracted into the accommodating box; after the slag scraping seat is retracted into the accommodating box, the limiting block and the limiting seat are in contact with each other, which can limit the reverse rotation of the swivel base. Controlling the threaded rod to continue to rotate in the reverse direction can cause relative rotation between the threaded rod and the swivel base, and the swivel base can drive the accommodating box to slide in the reverse direction along the guide rod, and the operation is relatively convenient.

[0019] Optionally, the slag scraping seat includes an arc-shaped arc edge, the axis of the arc edge coincides with the rotation axis of the slag scraping seat, and the arc is in sliding contact with the accommodating box at the slag receiving port.

[0020] By adopting the above technical solution, when the slag scraping seat rotates, the arc edge abuts against the edge of the accommodating box at the slag receiving port, which is beneficial to reducing the spillage of sludge in the accommodating box at the slag receiving port.

[0021] Optionally, it further includes a liquid skimming pipe. A hoop member is provided on the box cover, the liquid skimming pipe is clamped in the hoop member, an avoidance hole for avoiding the liquid skimming pipe is hermetically opened through the accommodating box, a first liquid skimming hole and a second liquid skimming hole for the liquid skimming pipe to pass through are opened through the box cover, and one end of the liquid skimming pipe extends into the drum and the other end extends between the outer peripheral wall of the drum and the inner side wall of the fuel tank.

[0022] By adopting the above technical solution, the liquid skimming pipe can be fixed on the box cover relatively simply and conveniently. Adjusting the hoop member can also facilitate the adjustment of the liquid skimming pipe. The centrifuged oil in the drum can flow into the fuel tank for temporary storage through the liquid skimming pipe.

[0023] Optionally, both the first liquid skimming hole and the second liquid skimming hole are waist-shaped holes, and the length directions of the first liquid skimming hole and the second liquid skimming hole are parallel to each other.

[0024] By adopting the above technical solution, moving the liquid skimming pipe along the length direction of the waist-shaped hole can facilitate the adjustment of the distance between the end of the liquid skimming pipe and the inner peripheral wall of the drum, and can control the oil flowing into the liquid skimming pipe.

[0025] Optionally, the side of the accommodating box away from the box cover is open, and a box cover is detachably installed on the side of the accommodating box away from the box cover.

[0026] By adopting the above technical solution, after removing the box cover and opening the box cover of the accommodating box, it is convenient to take out the sludge contained in the accommodating box. After the accommodating box and the box cover are conveniently installed, the accommodating box can continue to store new sludge.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. When the rotary drum rotates, the slag scraping mechanism can scrape off the sludge on the inner peripheral wall of the rotary drum along the rotation direction of the rotary drum. When the slag scraping mechanism slides along the guide rod with the receiving groove, the slag scraping mechanism can scrape off the inner peripheral walls at different heights in the rotary drum, thereby effectively improving the scraping effect on the inner peripheral wall of the rotary drum and being able to send the sludge scraped off from the inner peripheral wall of the rotary drum into the receiving box for storage;

[0029] 2. Rotate the threaded rod to drive the rotating seat to rotate. The rotating seat can drive the first transmission rod to approach or move away from the slag scraping seat, and correspondingly, the second transmission rod can push the slag scraping seat to rotate reciprocally;

[0030] 3. Rotate the threaded rod. When the threaded rod drives the rotating seat to abut against the limit block, the limit block can limit the rotation of the rotating seat. When the threaded rod continues to rotate, the rotating seat rotates relative to the threaded rod, and it can make the rotating seat drive the receiving box to slide along the threaded rod.

Detailed Description of the Embodiment

[0036] The following further describes the present application in detail with reference to the attached Figures 1-4 drawings.

[0037] Refer toFigure 1 and Figure 2 , a common centrifugal oil filter includes a bracket 1 vertically placed on an oil tank. A fuel tank 2 is welded to the upper side of the bracket 1. A cylindrical drum 3 is rotatably connected inside the fuel tank 2. The upper end of the drum 3 is open, and the upper end of the drum 3 is provided with a reduced opening. When the drum 3 rotates and centrifuges the oil, it can reduce the spillage of the oil to the outside;

[0038] A rotating shaft 31 is coaxially and fixedly welded to the lower side of the drum 3. The rotating shaft 31 rotates and penetrates the lower side wall of the fuel tank 2, and the rotating shaft 31 is rotatably and sealingly connected to the fuel tank 2. A rotating motor 11 is also fixedly placed on the bracket 1. The output shaft of the rotating motor 11 is parallel to the rotating shaft 31, and a transmission belt for driving the rotating shaft 31 to rotate is provided between the rotating motor 11 and the rotating shaft 31. A control panel 12 is also fixedly placed on the upper side of the bracket 1. The control panel 12 is electrically connected to the rotating motor 11. Controlling the rotating motor 11 to drive the drum 3 to rotate can centrifuge the oil in the drum 3. The impurities in the oil in the drum 3 adhere to the inner peripheral wall of the drum 3. A liquid skimming pipe 22 is penetrated through the tank cover 21. One end of the liquid skimming pipe 22 extends into the drum 3 and the other end extends between the drum 3 and the fuel tank 2, and can introduce the centrifugally filtered oil into the fuel tank 2 for temporary storage.

[0039] The embodiment of the present application discloses an oil filtering system for a riveting machine. Referring to Figure 1 and Figure 2 , it includes a circular guide rod 211 fixedly and vertically welded to the lower side of the tank cover 21. The lower end of the guide rod 211 extends into the drum 3, and the guide rod 211 is parallel to the rotation axis of the drum 3. A horizontal circular receiving box 4 is slidably installed in the drum 3 on the guide rod 211; A buckle lock is provided between the tank cover 21 and the fuel tank 2. Two buckle locks are provided along the outer peripheral wall of the fuel tank 2, and more buckle locks can also be set according to needs. The two buckle locks can lock the tank cover 21 on the fuel tank 2 more conveniently. When the fuel tank 2 needs to be opened, the tank cover 21 can be very conveniently removed from the fuel tank 2. The receiving box 4 is smaller than the upper opening size of the drum 3, which is convenient for the operator to take out the receiving box 4 from the drum 3.

[0040] Referring to Figure 2 and Figure 3 , the receiving box 4 is hermetically and penetrated with a guide hole 41 for the guide rod 211 to slidably penetrate. Through the mutual cooperation of the guide rod 211 and the guide hole 41, the sliding of the receiving box 4 can be stably guided, improving the stability of the sliding of the receiving box 4. A slag receiving port 42 is penetrated through the outer peripheral wall of the receiving box 4, and a slag scraping mechanism 5 for scraping the oil sludge on the inner peripheral wall of the drum 3 is also provided on the receiving box 4.

[0041] Referring to Figure 2 and Figure 4, the lower side of the accommodation box 4 is open, and a box cover 43 is detachably arranged on the lower side inside the accommodation box 4. The guide rod 211 slidably penetrates through the box cover 43, and screws for locking the box cover 43 to the accommodation box 4 are arranged on the box cover 43. Six screws are arranged along the circumferential side of the box cover 43. Threaded holes adapted to the screws are formed on the side wall of the accommodation box 4, and through holes aligned with the threaded holes are formed on the box cover 43. After the screws are screwed into the threaded holes, the box cover 43 can be firmly locked on the accommodation box 4. After the screws are screwed counterclockwise, it is convenient for the operator to open the accommodation box 4, so as to take out the sludge contained in the accommodation box 4 from the accommodation box 4 and create space for the accommodation box 4 to accommodate sludge next time.

[0042] The slag scraping mechanism 5 includes a slag scraping seat 51 that is hermetically and rotatably connected to the upper side wall of the accommodation box 4 and a push-pull assembly 52 that drives the slag scraping seat 51 to rotate. The rotation axis of the slag scraping seat 51 is parallel to the guide rod 211. When the slag scraping seat 51 rotates clockwise, a part of the slag scraping seat 51 can extend out of the accommodation box 4 from the slag discharge port 42. Further, the slag scraping seat 51 can abut against the inner peripheral wall of the drum 3. A slag guiding groove 511 is also formed through the slag scraping seat 51, and the slag guiding groove 511 is only provided with openings at both ends.

[0043] When a part of the slag scraping seat 51 abuts against the inner peripheral wall of the drum 3, one end of the slag guiding groove 511 faces the abutting area between the slag scraping seat 51 and the inner peripheral wall of the drum 3, and the other end faces the inside of the accommodation box 4. The opening size of the slag guiding groove 511 gradually increases from the outer peripheral wall of the drum 3 towards the accommodation box 4, and the slag guiding groove 511 is located in the slag discharge port 42, which can facilitate the introduction of sludge into the accommodation box 4; the sludge scraped from the inner peripheral wall of the drum 3 can be sent into the slag box through the slag discharge port 42 for temporary storage. By temporarily storing the sludge on the inner peripheral wall of the drum 3, the frequency of opening and cleaning the fuel tank 2 can be reduced, which is beneficial to the continuous operation of the drum 3 in the fuel tank 2.

[0044] Refer to Figure 2 、 Figure 3 and Figure 4 , the slag scraping seat 51 includes an arc-shaped arc edge 512, and the arc axis of the arc edge 512 coincides with the rotation axis of the slag scraping seat 51. When the slag scraping seat 51 rotates, the side of the arc edge 512 away from the rotation axis of the slag scraping seat 51 slidably abuts against the accommodation box 4 at the slag discharge port 42, which can reduce the leakage of sludge at the slag discharge port 42.

[0045] The push-pull assembly 52 includes a swivel base 521, a rotating rod 522, a first transmission rod 523, and a second transmission rod 524. The swivel base 521 is rotatably connected to the upper side wall of the receiving box 4, and the upper end of the swivel base 521 protrudes above the receiving box 4, while the lower end of the swivel base 521 is located inside the receiving box 4. A threaded hole 5211 is formed through the swivel base 521, and the axis of the threaded hole 5211 coincides with the rotation axis of the swivel base 521. The rotating rod 522 is parallel to the guide rod 211, and the rotating rod is a threaded rod. The threaded rod is coaxially and threadedly inserted into the threaded hole 5211, and the swivel base 521 is connected to the threaded rod by a screw drive. Rotating the threaded rod can drive the swivel base 521 to rotate.

[0046] Referring to Figure 1 and Figure 2 , the upper end of the threaded rod passes through the box cover 21 and is rotatably connected to the box cover 21. To facilitate driving the threaded rod to rotate along its axis, a rotating member 24 for driving the threaded rod to rotate is provided on the box cover 21. The rotating member 24 is a bidirectional motor, and the housing of the rotating member 24 is welded to the upper side of the box cover 21. The threaded rod is coaxially welded to the output shaft of the rotating member 24. The rotating member 24 is electrically connected to the control panel 12 and can control the rotation of the rotating member 24.

[0047] Both the first transmission rod 523 and the second transmission rod 524 are located inside the receiving box 4, which can protect the first transmission rod 523 and the second transmission rod 524. One end of the first transmission rod 523 is welded to the swivel base 521. One end of the second transmission rod 524 is rotatably connected to the end of the first transmission rod 523 away from the swivel base 521, and the other end is rotatably connected to the slag scraping seat 51. The rotation axes at both ends of the second transmission rod 524 and the rotation axis of the slag scraping seat 51 are all coaxial with the rotation axis of the swivel base 521. By controlling the rotating member 24, the threaded rod can be driven to drive the swivel base 521 to rotate.

[0048] When the swivel base 521 rotates and drives the first transmission rod 523 close to the slag scraping seat 51, the first transmission rod 523 and the second transmission rod 524 cooperate with each other to be able to push the slag scraping seat 51 to rotate and move away from the swivel base 521, so that part of the swivel base 521 extends out of the receiving box 4. When the swivel base 521 rotates in the reverse direction and drives the first transmission rod 523 away from the slag scraping seat 51, the first transmission rod 523 and the second transmission rod 524 cooperate with each other to be able to drive the slag scraping seat 51 to rotate and approach the swivel base 521, which is convenient for receiving the slag scraping seat 51 into the receiving box 4, and the operation is relatively convenient.

[0049] To drive the receiving box 4 to slide along the length direction of the guide rod 211, a rectangular positioning seat 45 and a limiting seat 46 are welded to the upper side of the upper side wall of the receiving box 4. A limiting block 5212 is welded to the swivel base 521, and the limiting block 5212 is located between the positioning seat 45 and the limiting seat 46.

[0050] When the threaded rod drives the rotating seat 521 to rotate forward, the slag scraping seat 51 can partially extend out of the receiving box 4 and abut against the inner peripheral wall of the rotating drum 3, and the limiting block 5212 can abut against the positioning seat 45, so as to limit the forward rotation of the rotating seat 521. Further controlling the threaded rod to continue rotating forward can cause relative rotation between the threaded rod and the rotating seat 521, and the rotating seat 521 can drive the receiving box 4 to slide along the length direction of the threaded rod and approach the box cover 21. The rotation of the rotating drum 3 and the sliding of the slag scraping seat 51 cooperate with each other, and the slag scraping seat 51 can effectively scrape the sludge on the inner peripheral wall of the rotating drum 3, improving the cleaning effect of the inner peripheral wall of the rotating drum 3.

[0051] When the slag scraping seat 51 and the receiving box 4 move to a higher position, rotating the threaded rod in the reverse direction can drive the rotating seat 521 to rotate in the reverse direction, and drive the slag scraping seat 51 to rotate and retract into the receiving box 4. Continuing to rotate the threaded rod so that the limiting block 5212 abuts against the limiting seat 46 can limit the reverse rotation of the rotating seat 521. Making the threaded rod and the rotating seat 521 rotate relatively, the rotating seat 521 can drive the receiving box 4 to slide along the length direction of the threaded rod and move away from the box cover 21, which is convenient for driving the slag scraping seat 51 to scrape the inner peripheral wall of the rotating drum 3 again.

[0052] The threaded rod and the rotating seat 521 cooperate with each other to realize the slag scraping of the inner peripheral wall of the rotating drum 3 by the slag scraping seat 51, and at the same time, the lifting control of the receiving box 4 can be realized. In addition, when it is not necessary to clean the inner peripheral wall of the rotating drum 3, the receiving box 4 can be driven to rise and move away from the bottom wall of the rotating drum 3, and the sludge scraped from the inner peripheral wall of the rotating drum 3 can be temporarily stored, which can reduce the cleaning frequency of the operator opening the box cover 21. The receiving box 4 moving away from the bottom wall of the rotating drum 3 can reduce the influence on the centrifugation in the rotating drum 3 and ensure the centrifugal filtration effect of the oil liquid in the rotating drum 3.

[0053] Refer to Figure 1 and Figure 2 As shown in [relevant figure number] and [relevant figure number], a fixing seat 212 is integrally formed on the upper side wall of the box cover 21. A semi-circular groove is opened on the upper side of the fixing seat 212. A hoop member 6 is provided on the box cover 21. The hoop member 6 is in a rectangular block shape. The hoop member 6 is located on the fixing seat 212. A semi-circular arc-shaped groove 61 is opened on the lower side of the hoop member 6. The semi-circular groove and the arc-shaped groove 61 are aligned. The liquid skimming pipe 22 is located between the hoop member 6 and the fixing seat 212, and the liquid skimming pipe 22 passes through the arc-shaped groove 61. A screw hole is opened on the fixing seat 212, and a through hole aligned with the screw hole is penetrated on the hoop member 6. A bolt 7 is provided on the hoop member 6. After screwing the bolt 7 into the screw hole, it is relatively convenient to fix the liquid skimming pipe 22.

[0054] The cover 21 is provided with a first liquid draining hole 213 and a second liquid draining hole 214, and the accommodating box 4 is penetrated and hermetically provided with an avoiding hole 44 for avoiding the liquid draining pipe 22. The lengths of the first liquid draining hole 213, the second liquid draining hole 214, and the avoiding hole 44 are all parallel to the axial direction of the arc-shaped groove 61, which can facilitate the movement of the liquid draining pipe 22 and adjust the distance between the liquid draining pipe 22 and the inner peripheral wall of the drum 3, so as to adjust the oil liquid drained by the liquid draining pipe 22.

[0055] An oil inlet pipe 215 is welded through the cover 21. The oil inlet pipe 215 is perpendicular to the cover 21, and the lower end of the oil inlet pipe 215 extends into the drum 3. The accommodating box 4 is hermetically provided with an oil inlet hole 47 for the oil inlet pipe 215 to pass through. The bracket 1 is also provided with an oil pump 13. The oil outlet of the oil pump 13 is connected with an oil delivery pipe 131. The oil delivery pipe 131 includes a rubber pipe connected thereto. After the oil delivery pipe 131 is inserted into the oil inlet pipe 215, it can facilitate the feeding of the oil liquid to be filtered into the drum 3. An oil outlet is provided on the outer peripheral wall of the box body, and an oil outlet pipe 23 is connected to the box body at its outlet, which can facilitate the discharge of the centrifugally filtered oil liquid into the fuel tank 2 for storage or reuse.

[0056] The implementation principle of the oil filtering system of a riveting machine according to an embodiment of the present application is as follows: controlling the rotating member 24 to drive the threaded rod to rotate forward can drive the slag scraping seat 51 to rotate and abut against the inner peripheral wall of the drum 3. When the limiting block 5212 abuts against the positioning seat 45, continuing to rotate the threaded rod forward can cause the rotating seat 521 to drive the accommodating box 4 to slide upward. The sliding of the slag scraping seat 51 and the rotation of the drum 3 cooperate with each other, which can effectively clean the sludge on the inner peripheral wall of the drum 3;

[0057] Controlling the threaded rod to rotate reversely can drive the slag scraping seat 51 to rotate and retract into the accommodating box 4. Continuing to rotate the threaded rod so that the limiting seat 46 abuts against the limiting block 5212 can limit the reverse rotation of the rotating seat 521, and can further drive the rotating seat 521 to drive the accommodating box 4 to slide downward, facilitating the next cleaning of the inner peripheral wall of the drum 3;

[0058] The sludge scraped off by the slag scraping seat 51 can be fed into the accommodating box 4 for storage, realizing the automatic cleaning of the sludge on the inner peripheral wall of the drum 3, and overall improving the problem that the cleaning of the sludge is relatively inconvenient.

[0059] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
