Description

[0002] The crankshaft is an important component on the engine, and its material is usually made of carbon structural steel or ductile iron. The rotation of the crankshaft is the power source of the engine and also the power source of the entire mechanical system. During the machining process of the crankshaft, quenching is one of the key processes, which directly affects the performance and quality of the crankshaft.

[0003] However, there are many problems in the existing crankshaft quenching technology. For example, some quenching devices are difficult to quench the crankshaft quickly and sufficiently, resulting in low quenching efficiency and insufficient quenching, making it difficult to ensure the quenching and machining quality of the crankshaft. When some devices are used for batch crankshaft quenching processing, due to the special structure of the crankshaft rotation, when the crankshaft is clamped and quenched, the quickly placed crankshaft cannot be accurately and quickly clamped at the end, resulting in unstable clamping and conveying during continuous quenching of the crankshaft, thus greatly reducing the quenching efficiency.

[0016] A quenching method based on crankshaft production includes the following steps:

[0017] S1. Place the crankshaft: Vertically place the crankshaft to be quenched inside the limit positioning cylinder, and the bottom of the crankshaft is supported by the rubber gasket on the adjustment tray;

[0018] S2. Adjust the clamping position: Start the sixth electric push rod to drive the adjustment tray to move downward, so that the upper end of the crankshaft is exposed to the clamping range of the clamping collar. The laser distance sensor detects the position of the detection plate and feeds back the moving distance of the adjustment tray to ensure the precise positioning of crankshafts of different specifications;

[0019] S3. Clamping and fixing: Start the third electric push rod to drive the symmetrically distributed clamping rings to move inward, clamp the upper end of the crankshaft through the inner rubber ring gasket. Start the fifth electric push rod to horizontally slide and adjust the tray to move it out from below the limit positioning cylinder to avoid interfering with subsequent operations;

[0020] S4. Induction heating quenching: Start the super audio frequency induction heating machine, set the heating parameters, start the fourth electric push rod to drive the limit positioning cylinder and the clamped crankshaft to move downward, so that the crankshaft enters the heating area of the induction heating coil, and quickly heat the crankshaft to the quenching temperature through the induction heating coil. After heating is completed, maintain for a short time to ensure uniform temperature;

[0021] S5. Rotating and uniform cooling: After the crankshaft is heated, it continues to move downward and enters the internal rotating cooling ring. Open the cooling medium delivery pipe to deliver high-pressure water or quenching oil into the rotating cooling ring. Start the motor to drive the driving gear to mesh with the rotating gear ring, drive the rotating cooling ring to rotate forward and backward, and the nozzle rotates with the rotating cooling ring to evenly spray the cooling medium on the surface of the crankshaft to achieve quenching without dead angles. Adjust the height of the lifting control plate through the second electric push rod to adapt to the cooling requirements of crankshafts with different diameters;

[0022] S6. Secondary cooling and collection: After the initial cooling is completed, the crankshaft continues to move downward and disengages from the rotating cooling ring. Start the first electric push rod to push the slidably clamped cooling box out of the support limit base to the receiving position. The crankshaft falls into the coolant in the cooling box for sufficient cooling. Open the valve of the discharge pipe to discharge the coolant, take out the quenched crankshaft, and perform subsequent quality inspections.

[0023] The present invention has at least the following beneficial effects:

[0024] (1) Through the clamping and adjusting main body provided in the present invention, the position adjusting part and the lifting and clamping part in it cooperate with each other to make it possible to accurately and stably clamp and fix the end of crankshafts with different specifications and lengths during quenching, which is convenient for clamping and moving the crankshaft. Moreover, the lifting and clamping part and the position adjusting part can quickly and efficiently add crankshaft blanks during continuous quenching, greatly improving the quenching efficiency. The laser distance measuring sensor can accurately detect the moving and lifting position of the detection plate, and thus indirectly detect the movement and position of the adjusting tray and the rubber gasket, so that the adjusting tray and the rubber gasket can move different models of crankshafts downward by an accurate distance, enabling the clamping rings to accurately clamp and fix the upper end positions of different models and sizes of crankshafts, so that different sizes and models of crankshafts can be accurately clamped at the end, making it convenient to clamp the crankshaft and perform sufficient and stable quenching treatment. The clamping rings are made of high-temperature resistant materials, which can fully ensure the quenching treatment of the clamped end of the crankshaft without affecting the clamping rings.

[0025] (2) The quenched crankshaft of the present invention can be fully cooled. Start the electric motor to drive the drive gear to rotate forward and backward, so that the rotating cooling ring rotates forward and backward on the limit support clamping ring by means of the rotating toothed ring, making the spraying and cooling of each nozzle on the crankshaft uniform without dead angles. After continuous heating and cooling, start the first electric push rod to make the cooling box slide outwards from the inside of the support limit base, and then make the quenched crankshaft fall into the inside of the cooling box, and it can be taken out after rapid cooling through the coolant and other media contained in the cooling box.

[0026] (3) The present invention can fully quench and cool the clamped end of the crankshaft. After the crankshaft passes through the inside of the induction heating coil and the cooling part, at this time, the bottom end of the crankshaft enters the inside of the auxiliary adaptive clamping device. Start the seventh electric push rod to clamp and fix the bottom of the crankshaft through the first clamping end. By starting the eighth electric push rod, the symmetrically distributed rotating clamping plates and the eighth electric push rod can clamp and fix the longer crankshaft located inside the sliding adjustment seat, so that the bottom of the crankshaft is clamped and fixed. At this time, the clamped state of the upper end of the crankshaft is in contact, so that the clamped position of the upper end of the crankshaft can be fully quenched inside the induction heating coil. And start the ninth electric push rod to control the sliding adjustment seat to lift along the track plate, so that the crankshaft lifts inside the induction heating coil and the cooling part, completing multiple quenching and cooling processes. And through the set auxiliary adaptive clamping device, the two ends of the crankshaft can be alternately clamped and fixed, so that after the upper end of the crankshaft is clamped, the bottom end can be clamped and then lifted and moved inside the induction heating coil, fully making the clamped end of the crankshaft be fully quenched without dead angles inside the induction heating coil.

A motor 19 is fixedly installed at the bottom of the support disk 18, and the driving end of the motor 19 is fixedly connected to the middle of the driving gear 17.

[0042] As Figure 6 shown, the clamping and adjusting main body 10 includes a position adjusting part 22 and a lifting clamping part 23. The position adjusting part 22 is arranged on the lifting clamping part 23.

[0043] like Figure 7 As shown, the lifting clamping part 23 includes a track limit plate 24, a limit positioning cylinder 25, a clamping clamp ring 28, a third electric push rod 29, a mounting frame 30, a driving limit frame 31, a limit vertical rod 32, a support vertical frame 33 and a fourth electric push rod 34. The track limit plate 24 is fixedly connected to both sides of the limit positioning cylinder 25, the driving limit frame 31 is fixedly installed on the side end of the limit positioning cylinder 25 away from the track limit plate 24 by bolts, the limit vertical rod 32 is symmetrically arranged, the driving limit frame 31 is slidably clamped on the limit vertical rod 32, the support vertical frame 33 is symmetrically distributed, and the fourth electric push rod 34 is fixedly installed on the support vertical frame 33.

[0044] like Figure 8 As shown, the position adjustment part 22 includes a fifth electric push rod 35, a sliding mounting block 36, a sixth electric push rod 37, a detection plate 38 and a rubber gasket 39. The sixth electric push rod 37 is symmetrically arranged, and the bottom end of the sixth electric push rod 37 is fixedly connected to the upper ends of both sides of the adjustment tray 40. The sliding mounting block 36 is fixedly installed on the upper end of the sixth electric push rod 37. The fifth electric push rod 35 is symmetrically distributed, and the front end of the fifth electric push rod 35 is fixedly connected to the middle part of the sliding mounting block 36. Starting the fifth electric push rod 35 drives the sliding mounting block 36 to slide horizontally along the track limit plate 24, so that the adjustment tray 40 and the rubber gasket 39 are slid away from the bottom of the limit positioning cylinder 25, which will not affect the crankshaft from continuing to move downward.

[0045] A rubber gasket 39 is fixedly installed at the middle of the upper end of the adjustment tray 40, and a rubber ring pad is fixedly arranged on the inner side of the clamping ring 28 to play a protective and anti-slip role.

[0046] The bottom ends of the two supporting frames 33 are fixedly connected to the upper ends of the first supporting column 5 and the second supporting column 11 respectively. The fixed connecting plate 12 is fixedly connected to the upper bottom of the supporting limit base 6 by bolts. The rotating cooling ring 14 is located directly below the induction heating coil 1, and the limit positioning cylinder 25 is located directly above the induction heating coil 1, so as to realize precise cooling and heating treatment.

[0047] The sliding installation block 36 is slidably clamped inside the track limiting plate 24, the fifth electric push rod 35 is fixedly installed on the track limiting plate 24, and the adjusting tray 40 is located directly below the limiting positioning cylinder 25, which can stably support the bottom of the crankshaft.

[0048] The working principle of Embodiment 1 is as follows: First, place the crankshaft inside the limit positioning cylinder 25 that is adaptively set to the crankshaft. At this time, adjust the tray 40 and the rubber gasket 39 to be located at the bottom of the limit positioning cylinder 25, so that the crankshaft to be quenched can be quickly placed inside the limit positioning cylinder 25, enabling quick and convenient feeding and realizing continuous quenching treatment. After the crankshaft is quickly placed inside the limit positioning cylinder 25, according to the different lengths of the crankshaft, start the sixth electric push rod 37 to make the adjusting tray 40 and the rubber gasket 39 move downward accurately by a specified distance, so that the crankshaft supported by the adjusting tray 40 and the rubber gasket 39 moves downward synchronously by a specified distance. At this time, the end of the upper end of the crankshaft moves between the symmetrically distributed clamping rings 28. Then, start the symmetrically distributed third electric push rods 29 at the same time. Through the third electric push rods 29, make the symmetrically distributed clamping rings 28 move synchronously towards the middle of the lower part of the limit positioning cylinder 25, so that the symmetrically distributed clamping rings 28 clamp and fix the upper end position of the crankshaft. Then, start the sixth electric push rod 37 to make the adjusting tray 40 and the rubber gasket 39 move downward by another distance. Start the fifth electric push rod 35 to drive the sliding mounting block 36 to slide horizontally along the track limiting plate 24, so that the adjusting tray 40 and the rubber gasket 39 slide away from below the limit positioning cylinder 25. Then, start the fourth electric push rod 34. Through the fourth electric push rod 34, make the driving limit frame 31 drive the limit positioning cylinder 25 and the crankshaft clamped and fixed at the bottom of the limit positioning cylinder 25 to move downward and insert into the induction heating coil 1 to achieve rapid heating and quenching treatment. After the crankshaft is heated and moves out downward from the inside of the induction heating coil 1, it moves into the rotating cooling ring 14. At this time, the delivery pipe at the bottom of the rotating cooling ring 14 conveys high-pressure water flow into the rotating cooling ring 14 through an external water delivery hose, and then sprays water mist from each nozzle 13 to quickly cool down the crankshaft moving through the rotating cooling ring 14. And start the motor 19 to drive the driving gear 17 to rotate forward and backward, so that the rotating cooling ring 14 rotates forward and backward on the limit support ring 15 by means of the rotating gear ring 16, making the spraying and cooling of each nozzle 13 on the crankshaft uniform without dead angles. After continuous heating and cooling, start the first electric push rod 8 to make the cooling box 3 slide outwards from the inside of the support limit base 6, and then make the quenched crankshaft fall into the inside of the cooling box 3. After quickly cooling down through the cooling medium such as the coolant contained in the cooling box 3, it can be taken out. The lifting control plate 20 can be controlled to lift and lower through the second electric push rod 21, so that the lifting and lowering of the rotating cooling ring 14 and the nozzle 13 can be controlled, and the use positions of the rotating cooling ring 14 and the nozzle 13 can be adaptively adjusted.

[0049] A quenching method based on crankshaft production includes the following steps:

[0050] S1. Place the crankshaft: Vertically place the crankshaft to be quenched inside the limit positioning cylinder 25, and support the bottom of the crankshaft with the rubber gasket 39 on the adjustment tray 40;

[0051] S2. Adjust the clamping position: Start the sixth electric push rod 37 to drive the adjustment tray 40 to move downward, so that the upper end of the crankshaft is exposed to the clamping range of the clamping collar 28. The laser distance sensor 26 detects the position of the detection plate 38 and feeds back the moving distance of the adjustment tray 40 to ensure the precise positioning of crankshafts of different specifications;

[0052] S3. Clamp and fix: Start the third electric push rod 29 to drive the symmetrically distributed clamping collars 28 to move inward, clamp the upper end of the crankshaft through the inner rubber ring gasket, and start the fifth electric push rod 35 to laterally slide the adjustment tray 40 to move it out from below the limit positioning cylinder 25 to avoid interfering with subsequent operations;

[0053] S4. Induction heating quenching: Start the ultra-audio frequency induction heating machine 9, set the heating parameters, start the fourth electric push rod 34 to drive the limit positioning cylinder 25 and the clamped crankshaft to move downward, so that the crankshaft enters the heating area of the induction heating coil 1, and quickly heat the crankshaft to the quenching temperature through the induction heating coil 1. After heating is completed, maintain for a short time to ensure uniform temperature;

[0054] S5. Rotating and uniform cooling: After the crankshaft is heated, it continues to move downward and enters the rotating cooling ring 14. Open the cooling medium delivery pipe to deliver high-pressure water or quenching oil into the rotating cooling ring 14. Start the motor 19 to drive the driving gear 17 to mesh with the rotating gear ring 16, drive the rotating cooling ring 14 to rotate forward and backward, and the nozzle 13 rotates with the rotating cooling ring 14 to evenly spray the cooling medium on the surface of the crankshaft to achieve dead-angle-free quenching. Adjust the height of the lifting control plate 20 through the second electric push rod 21 to adapt to the cooling requirements of crankshafts of different diameters;

[0055] S6. Secondary cooling and collection: After the initial cooling is completed, the crankshaft continues to move downward and disengages from the rotating cooling ring 14. Start the first electric push rod 8 to push the slidably clamped cooling box 3 out of the support limit base 6 to the receiving position. The crankshaft falls into the coolant in the cooling box 3 for sufficient cooling. Open the valve of the discharge pipe 4 to discharge the coolant, take out the quenched crankshaft, and perform subsequent quality inspection.

[0058] When implementing this embodiment, the laser distance sensor 26 can accurately detect the position of the detection plate 38 moving up and down, so as to indirectly detect the movement and position of the adjustment tray 40 and the rubber gasket 39, enabling the adjustment tray 40 and the rubber gasket 39 to move different models of crankshafts downward by an accurate distance, so that the clamping collar 28 can accurately clamp and fix the upper end positions of different models and sizes of crankshafts, enabling different sizes and models of crankshafts to be accurately clamped and fixed at the end.
