Abstract
Description
Technical Field
[0001] This invention belongs to the field of driver housing technology, and particularly relates to a tooling for anti-deformation machining of ductile iron parts for driver housings. Background Technology
[0002] The ductile iron components used in the drive unit housing are high-performance cast components formed through spheroidization and inoculation treatment. The graphite inside is distributed in a spherical shape, effectively retaining the excellent casting properties of cast iron while significantly improving the overall mechanical properties of the material. This casting possesses good strength, toughness, and rigidity, while also exhibiting excellent vibration damping, compressive strength, and deformation resistance, enabling it to stably bear various loads during drive unit operation. Utilizing mature casting technology, ductile iron components can be precisely molded to meet the complex structures required for drive unit housings, fulfilling basic functional requirements such as housing installation, sealing, and protection. It provides reliable external protection and structural support for the internal motor, transmission, and control components of the drive unit, making it a widely used metal component in drive unit housing manufacturing in the industrial field.
[0003] In the production of ductile iron parts, in order to prevent the finished product from deforming during use, the cast iron parts are often annealed to improve the deformation resistance of the finished product. However, during the annealing process, the outer wall of the cast iron parts will have debris due to continuous high temperature. This debris will fall into the equipment. Due to the high temperature inside the equipment, it is difficult for personnel to clean up this debris in a short time. It will require manual cleaning later, which is time-consuming and labor-intensive. Summary of the Invention
[0004] This invention provides a tooling fixture for preventing deformation of ductile iron drive housing parts, in order to solve existing problems.
[0005] This invention provides a tooling for preventing deformation machining of ductile iron drive housing parts, comprising: An annealing furnace body, wherein several flame heads are fixedly installed on both sides of the inner wall of the annealing furnace body, and a heat insulation component is provided on one side of the annealing furnace body; A material placement plate is slidably installed inside the annealing furnace. A scraper is fixedly installed at the bottom of the material placement plate. Two clamping rods and a clamping block are provided on the material placement plate. A linkage rod is rotatably installed at the bottom of the clamping block. A fixed column is fixedly installed at the bottom of the material placement plate. A counterweight block is slidably installed on the fixed column and on one side of the linkage rod. A dust collection assembly is located inside the burner head and is used to collect iron slag inside the annealing furnace.
[0006] The operator places the ductile iron part to be annealed on the placement plate between two clamping rods. Then, the operator pulls the extension rod out of the clamping rods until the top block is above the top of the ductile iron part. The top block is then rotated towards the ductile iron part; under gravity, the top block presses down on the ductile iron part. Simultaneously, the counterweight moves downwards along the fixed column due to gravity, pulling the linkage rod downwards. As the linkage rod is pulled, it causes the clamping block to move along the adjusting groove towards the fixed column. At the same time, the anti-detachment block moves synchronously along the anti-detachment groove. Simultaneously, the clamping block causes the clamping rod and extension rod to contact one side of the ductile iron part, thus ensuring that the ductile iron part does not slip. The material plate moves, and then the personnel push the material plate carrying the ductile iron parts back into the annealing furnace. At this time, the slider will continue to move along the slide groove. After the material plate is completely inside the annealing furnace, the personnel control the motor. The output end of the motor will drive the winding roller to rotate. The high-strength suspension rope will continue to unwind as the winding roller rotates. At the same time, the heat shield will drive the guide rail to move continuously downward along the guide groove. Meanwhile, the roller will also continue to roll in the guide groove until one side of the heat shield blocks one side of the annealing furnace. Finally, the personnel turn on the flame head. At this time, the flame head will continuously heat and anneal the ductile iron parts in the annealing furnace to ensure that the subsequent finished products can be protected from deformation.
[0007] The debris generated during the annealing of ductile iron parts by placing them on a feeding plate and fixing them in the annealing furnace will fall from the feeding plate into the annealing furnace. When the ductile iron parts on the feeding plate are annealed and the feeding plate is moved outward to be removed, the feeding plate will drive the scraper to scrape the inner wall of the annealing furnace. When the feeding plate moves the ductile iron parts to the outermost side for easy removal by personnel, the scraper will collect the debris in the annealing furnace into the collection trough and into the collection box, where it will be collected in the collection drawer.
[0008] Preferably, the thermal insulation component includes: The outer frame is fixedly installed on one side of the annealing furnace body. A protective shell is fixedly installed on the top of the outer frame. A winding roller is rotatably installed inside the protective shell. A high-strength suspension rope is fixedly connected to the outer wall of the winding roller. An insulating door is slidably installed inside the outer frame and located on one side of the annealing furnace body. The top of the insulating door is fixedly connected to the bottom of a high-strength suspension rope.
[0009] Preferably, guide grooves are provided on both sides of the inner wall of the outer frame, and guide rails fixed to the door are slidably installed in the guide grooves. Several rollers are rotatably installed on both sides of the guide rails, and one side of the rollers contacts the inner wall of the guide groove.
[0010] Preferably, a motor is fixedly installed on one side of the outer frame, the output end of the motor passes through the outer frame and is coaxially connected to the take-up roller, and the output end of the motor is rotatably connected to the outer frame.
[0011] Preferably, the ash collection component includes: A collection trough is provided inside the annealing furnace. A collection box is fixedly installed at the bottom of the collection trough and below the annealing furnace. Two linkage blocks are fixedly installed on one side of the collection box, and a locking groove is provided on the top of the linkage blocks. A collection drawer is slidably installed on one side of a collection box. One side of the collection drawer passes through the collection box and extends into the collection box. Two side blocks are fixedly installed on one side of the collection drawer and between two linkage blocks. Each of the two side blocks is provided with a follower block. A pull rod is fixedly installed on one side of the two follower blocks. A locking rod that is adapted to engage with a locking groove is fixedly installed on one side of the follower block. The bottom of the locking rod is in contact with one side of the linkage block.
[0012] Preferably, a linkage groove is provided on one side of the side block, the follower block is slidably connected to the linkage groove, and an inner groove is provided on both sides of the inner wall of the linkage groove, and an inner block fixed to the follower block is slidably installed in the inner groove.
[0013] Preferably, inner rails are fixedly installed on both sides of the inner wall of the annealing furnace body and below the burner head. A sliding groove is provided on the top of the inner rail, and a slider fixed to the material plate is slidably installed in the sliding groove.
[0014] Preferably, the top of the material placement plate is provided with an adjustment groove that is adapted to slide with the clamping block, and anti-detachment grooves are provided on both sides of the inner wall of the adjustment groove. An anti-detachment block that is fixed to the clamping block is slidably installed in the anti-detachment groove.
[0015] Preferably, an extension rod is slidably installed inside the clamping rod, and both the extension rod and the clamping rod have anti-slip textures on one side.
[0016] Preferably, a top block is rotatably mounted on the top of the extension rod.
[0017] Beneficial effects:
[0018] 1. By placing the ductile iron parts on the feeding plate and fixing them in place, the debris generated during annealing in the annealing furnace will fall from the feeding plate into the annealing furnace. When the ductile iron parts on the feeding plate are annealed and the feeding plate is moved outward to remove them, the feeding plate will drive the scraper to scrape the inner wall of the annealing furnace. When the feeding plate moves the ductile iron parts to the outermost side for easy removal by personnel, the scraper will collect the debris in the annealing furnace into the collection trough and into the collection box and collection drawer. Therefore, there is no need for personnel to manually clean the debris in the annealing furnace, saving time and effort.
[0019] 2. By using the clamping rods on the placement plate, when the ductile iron part is placed on the placement plate and located between the two clamping rods, the counterweight will pull the linkage rod downward under the action of gravity, thereby driving the clamping block and clamping rods closer to the ductile iron part, thus fixing the ductile iron part to be annealed on the placement plate. This allows ductile iron parts of different sizes to be fixed on the placement plate, preventing them from moving during annealing.
[0020] 3. The extension rod can extend upwards to accommodate ductile iron parts of different heights. At the same time, the top block ensures that the extension rod will not return to its original position after being fitted with the ductile iron part, thus ensuring the stability of the extension rod when fixing the ductile iron part.

[0030] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0031] This invention provides, for example Figures 1-8 The tooling shown is a deformation-resistant machining fixture for a driver housing-type ductile iron part, comprising: Annealing furnace body 1, several flame heads 2 are fixedly installed on both sides of the inner wall of annealing furnace body 1, and a heat insulation component is provided on one side of annealing furnace body 1. The material feeding plate 26 is slidably installed inside the annealing furnace body 1. A scraper 28 is fixedly installed at the bottom of the material feeding plate 26. Two clamping rods 36 and a clamping block 34 are provided on the material feeding plate 26. A linkage rod 33 is rotatably installed at the bottom of the clamping block 34. A fixed column 31 is fixedly installed at the bottom of the material feeding plate 26. A counterweight block 32 is slidably installed on the fixed column 31 and on one side of the linkage rod 33. The ash collection component is located inside the burner head 2 and is used to collect the iron slag inside the annealing furnace body 1.
[0032] It is worth noting that motor 4 is controlled by a PLC to start and stop, which is a well-known existing technology in this field, so it will not be elaborated here.
[0033] Furthermore, the operator places the ductile iron part to be annealed on the placement plate 26 between the two clamping rods 36. Then, the operator pulls the extension rod 37 out of the clamping rods 36 until the top block 38 is higher than the top of the ductile iron part. The top block 38 is then rotated towards the ductile iron part. Under gravity, the top block 38 presses down on the ductile iron part. Simultaneously, the counterweight 32 moves downwards along the fixed column 31 due to gravity, pulling the linkage rod 33 downwards. When pulled, the linkage rod 33 causes the clamping block 34 to move along the adjusting groove 29 towards the fixed column 31. Simultaneously, the anti-detachment block 35 moves synchronously along the anti-detachment groove 30. At the same time, the clamping block 34 causes the clamping rod 36 and the extension rod 37 to contact one side of the ductile iron part, thus ensuring the ductile iron part is properly annealed. The ductile iron parts will not move on the placement plate 26. Then, the personnel push the placement plate 26 containing the ductile iron parts back into the annealing furnace body 1. At this time, the slider 27 will continue to move along the slide groove 25. After the placement plate 26 is completely inside the annealing furnace body 1, the personnel control the motor 4. The output end of the motor 4 will drive the winding roller 5 to rotate. The high-strength suspension rope 11 will continue to unwind as the winding roller 5 rotates. At the same time, the heat shield 8 will drive the guide rail 9 to move continuously downward along the guide groove 7. At the same time, the roller 10 will also continue to roll in the guide groove 7 until one side of the heat shield 8 blocks one side of the annealing furnace body 1. Finally, the personnel turn on the flame head 2. At this time, the flame head 2 will continuously heat and anneal the ductile iron parts in the annealing furnace body 1 to ensure that the subsequent finished products can be protected from deformation.
[0034] The debris generated during the annealing of ductile iron parts by placing them on the feeding plate 26 and fixing them in the annealing furnace body 1 will fall from the feeding plate 26 into the annealing furnace body 1. When the annealing of the ductile iron parts on the feeding plate 26 is completed and the feeding plate 26 is moved outward and removed, the feeding plate 26 will drive the scraper 28 to scrape the inner wall of the annealing furnace body 1. When the feeding plate 26 moves the ductile iron parts to the outermost side for easy removal by personnel, the scraper 28 will collect the debris in the annealing furnace body 1 and scrape it into the collection trough 12 and into the collection box 13 and collect it in the collection drawer 14.
[0035] In this embodiment, the heat insulation component includes: The outer frame 3 is fixedly installed on one side of the annealing furnace body 1. A protective shell 6 is fixedly installed on the top of the outer frame 3. A winding roller 5 is rotatably installed inside the protective shell 6. A high-strength suspension rope 11 is fixedly connected to the outer wall of the winding roller 5. The insulating door 8 is slidably installed inside the outer frame 3 and located on one side of the annealing furnace body 1. The top of the insulating door 8 is fixedly connected to the bottom of the high-strength suspension rope 11.
[0036] Furthermore, the insulation door 8 can ensure that the ductile iron parts inside the annealing furnace body 1 are kept at a high temperature during heating and annealing, thus preventing the high temperature from affecting the surrounding personnel.
[0037] In this embodiment, guide grooves 7 are provided on both sides of the inner wall of the outer frame 3. A guide rail 9 fixed to the door 8 is slidably installed in the guide groove 7. Several rollers 10 are rotatably installed on both sides of the guide rail 9. One side of the roller 10 is in contact with the inner wall of the guide groove 7.
[0038] Furthermore, the guide rail 9 and roller 10, in conjunction with the guide groove 7, ensure that the insulation door 8 always moves up and down within the outer frame 3, effectively avoiding the problem of the insulation door 8 getting stuck during movement.
[0039] In this embodiment, a motor 4 is fixedly installed on one side of the outer frame 3. The output end of the motor 4 passes through the outer frame 3 and is coaxially connected to the winding roller 5. The output end of the motor 4 is rotatably connected to the outer frame 3.
[0040] Furthermore, the motor 4 can stably control the rotation of the take-up roller 5, thereby ensuring that the take-up roller 5 can drive the high-strength suspension rope 11 to take up and unwind.
[0041] In this embodiment, the ash collection component includes: A collection trough 12 is provided inside the annealing furnace body 1. A collection box 13 is fixedly installed at the bottom of the collection trough 12 and below the annealing furnace body 1. Two linkage blocks 18 are fixedly installed on one side of the collection box 13. A locking groove 19 is provided on the top of the linkage block 18. A collection drawer 14 is slidably installed on one side of a collection box 13. One side of the collection drawer 14 passes through the collection box 13 and extends into the collection box 13. Two side blocks 15 are fixedly installed on one side of the collection drawer 14 and between two linkage blocks 18. Each side block 15 is provided with a follower block 20. The same pull rod 23 is fixedly installed on one side of the two follower blocks 20. A locking rod 22 that is matched and engaged with the locking groove 19 is fixedly installed on one side of the follower block 20. The bottom of the locking rod 22 is in contact with one side of the linkage block 18.
[0042] Furthermore, the collection drawer 14 can collect the debris that enters the collection box 13, making it easier for personnel to process the collected debris in a concentrated manner later.
[0043] In this embodiment, a linkage groove 16 is provided on one side of the side block 15, and the follower block 20 is slidably connected to the linkage groove 16. An inner groove 17 is provided on both sides of the inner wall of the linkage groove 16, and an inner block 21 fixed to the follower block 20 is slidably installed in the inner groove 17.
[0044] Furthermore, through the cooperation of the inner block 21 and the inner groove 17, it can be ensured that the follower block 20 always moves along the linkage groove 16, and that the follower block 20 will not disengage from the linkage groove 16.
[0045] In this embodiment, inner rails 24 are fixedly installed on both sides of the inner wall of the annealing furnace body 1 and below the burner head 2. A sliding groove 25 is provided on the top of the inner rail 24, and a slider 27 fixed to the material plate 26 is slidably installed in the sliding groove 25.
[0046] Furthermore, through the cooperation of the slider 27 and the inner rail 24, it can be ensured that the material plate 26 moves smoothly in the annealing furnace body 1, thereby stably driving the ductile iron casting into the annealing furnace body 1 for annealing.
[0047] In this embodiment, the top of the material plate 26 is provided with an adjustment groove 29 that is slidably adapted to the clamping block 34. Anti-detachment grooves 30 are provided on both sides of the inner wall of the adjustment groove 29. Anti-detachment blocks 35 that are fixed to the clamping block 34 are slidably installed in the anti-detachment grooves 30.
[0048] Furthermore, by using the anti-detachment block 35 in conjunction with the anti-detachment groove 30, it can be ensured that the clamping block 34 can move stably along the material placement plate 26, thereby adapting to ductile iron parts of different widths.
[0049] In this embodiment, an extension rod 37 is slidably installed inside the clamping rod 36, and anti-slip textures are provided on one side of both the extension rod 37 and the clamping rod 36.
[0050] Furthermore, the extension rod 37 can be extended upwards to accommodate ductile iron parts of different heights.
[0051] In this embodiment, a top block 38 is rotatably mounted on the top of the extension rod 37.
[0052] Furthermore, the top block 38 ensures that the extension rod 37 will not return to its original position after it is fitted with the ductile iron part, thus ensuring the stability of the extension rod 37 when fixing the ductile iron part.
[0053] Working principle: First, the operator pulls the material plate 26 out of the annealing furnace body 1. Then, the operator places the ductile iron casting to be annealed on the material plate 26 between the two clamping rods 36. Next, the operator pulls the extension rod 37 out of the clamping rods 36 until the top block 38 is higher than the top of the ductile iron casting. Then, the operator rotates the top block 38 toward the ductile iron casting. Under the action of gravity, the top block 38 will press down on the ductile iron casting. At the same time, the counterweight 32 will move downward along the fixed column 31 due to gravity, and the counterweight 32 will pull the linkage rod 33 downward. When the linkage rod 33 is pulled, it causes the clamping block 34 to move along the adjusting groove 29 toward the fixed column 31. At the same time, the anti-detachment block 35 moves synchronously along the anti-detachment groove 30. Simultaneously, the clamping block 34 causes the clamping rod 36 and the extension rod 37 to contact one side of the ductile iron part, thereby ensuring that the ductile iron part will not move on the placing plate 26. Then, the personnel push the placing plate 26 carrying the ductile iron part back into the annealing furnace body 1. At this time, the slider 27 will continue to move along the sliding groove 25. After the placing plate 26 is completely inside the annealing furnace body 1, the personnel control the motor 4. The output of motor 4 drives the winding roller 5 to rotate, and the high-strength suspension rope 11 continuously unwinds as the winding roller 5 rotates. At the same time, the insulating door 8 drives the guide rail 9 to move continuously downward along the guide groove 7, and the roller 10 also continuously rolls in the guide groove 7 until one side of the insulating door 8 blocks one side of the annealing furnace body 1. Finally, the personnel turn on the flame head 2, which continuously heats and anneals the ductile iron parts in the annealing furnace body 1 to ensure that the subsequent finished products can be protected against deformation. After annealing, the personnel control the process in the same way as described above. The heat exchanger 8 moves upward to reset and pulls the material plate 26 downward, thereby causing the annealed ductile iron part on the material plate 26 to extend out. At the same time, the material plate 26 will drive the scraper 28 to continuously scrape along the inner bottom wall of the annealing furnace body 1. After the material plate 26 has completely extended the ductile iron part, the scraper 28 will scrape all the debris in the annealing furnace body 1 into the collection box 13 and collect it in the collection drawer 14. At the same time, the personnel can directly remove the annealed ductile iron part on the material plate 26 and replace it with the next ductile iron part that needs to be annealed.
[0054] When cleaning debris from the collection drawer 14, the operator first grasps the lever 23 and lifts it upwards. The lever 23 will cause the follower block 20 to move along the linkage groove 16. At the same time, the follower block 20 will cause the locking lever 22 to separate upwards within the locking groove 19. Once the locking lever 22 is completely disengaged from the locking groove 19, the operator can simply pull the lever 23 downwards towards the insulated door 8. The lever 23 will then cause the collection drawer 14 to separate independently from the collection box 13 via the side block 15. After cleaning the debris collected in the drawer 14, simply insert the drawer 14 back into the collection box 13 and let it fit against the inner wall of the collection box 13. As the locking rod 22 moves towards the linkage block 18 along with the drawer 14, the bottom of the locking rod 22 will contact one side of the linkage block 18 and move upward at the same time until the drawer 14 is completely fitted against the inner wall of the collection box 13. Then, the locking rod 22 will automatically lock into the locking groove 19 under the action of gravity, ensuring that the drawer 14 will not automatically detach from the collection box 13.
