Description

Technical Field

[0001] This invention relates to the field of heat treatment equipment technology, and in particular to an integrated device and processing method for induction hardening and tempering of motorcycle crankshaft connecting rods. Background Technology

[0002] A patent document with publication number CN115354135A discloses an integrated device and processing method for induction hardening and tempering of motorcycle crankshaft connecting rods. The crankshaft connecting rod is axially clamped and fixed by pins on both sides of a base plate and a turntable fixture, and driven to rotate coaxially by a servo motor. High-frequency and low-frequency induction coils are respectively installed at the upper and lower ends of the connecting rod. Simultaneous energization heats the upper end (threaded and splined areas) to a higher temperature and the lower end to a lower temperature, respectively. Then, a high-pressure water spray device above the high-frequency coil rapidly cools the upper end with water to complete localized quenching, while the lower end relies on natural cooling at room temperature to complete localized tempering. This allows for simultaneous quenching and tempering of different areas of the connecting rod in the same station and process. This technical solution integrates the previously separate quenching and tempering processes, significantly simplifying the process steps, improving production efficiency, saving production costs, and accurately achieving the zoned performance requirements of "high hardness and wear resistance at the upper end, and high impact toughness at the lower end" for the crankshaft connecting rod, ensuring the manufacturing quality of the parts. However, the installation positions and relative spacing of the high-frequency induction coil, low-frequency induction coil, and high-pressure water spray device in the above scheme are usually fixed and cannot be adjusted, or the processing area can only be changed by replacing the entire coil assembly. As a result, when the crankshaft connecting rod to be processed has different total lengths, different upper quenching zone lengths, or different lower tempering zone lengths, the device cannot flexibly and independently adjust the axial range of the quenching and tempering zones according to the actual dimensions, and it is also difficult to fine-tune the coupling gap between the induction coil and the workpiece surface. This results in insufficient positional accuracy of local quenching and tempering, unclear heating and cooling boundaries when performing zoned heat treatment on connecting rods of different specifications, which seriously affects the performance consistency of the upper high hardness, wear-resistant layer and the lower high toughness layer. Summary of the Invention

[0006] The position adjustment component includes a mounting frame, an adjusting screw, a rotating sleeve, a screw-driven rotation mechanism, and a height adjustment component. Each connecting frame has a mounting frame slidably mounted on it. Each adjusting screw corresponds to a mounting frame and is threadedly connected to the corresponding mounting frame, and is rotatably mounted on the connecting frame. Each rotating sleeve corresponds to a adjusting screw and is threadedly connected to the adjusting screw, and is rotatably mounted on the side sealing plate. The screw-driven rotation mechanism is connected to the adjusting screw and installed on the outside of the rotating disk, used to drive the two adjusting screws on a designated side to rotate.

[0007] The cooling component includes a rotating nozzle and a water outlet mechanism, wherein the rotating nozzle is disposed on the inner side of one of the side sealing plates; the water outlet mechanism is connected to the rotating nozzle and is mounted on the side sealing plate.

[0008] The bidirectional drive component includes a bidirectional threaded screw, a gear transmission mechanism, and a drive motor. The two sides of the bidirectional threaded screw are threadedly connected to the corresponding movable plates on both sides, and the bidirectional threaded screw is rotatably mounted on the corresponding rotating disk. The gear transmission mechanism is connected to the bidirectional threaded screw. The output shaft of the drive motor is connected to the gear transmission mechanism, and the drive motor is fixedly mounted on the outside of the rotating disk.

[0009] The height adjustment component includes a side guide plate, an internal gear plate, an adjustment gear, and a gear drive mechanism. The side guide plate is fixedly connected to the induction heating plate and slidably mounted on the mounting frame. The internal gear plate is fixedly connected to the induction heating plate and slidably mounted on the mounting frame.

[0011] The partition component includes a fixed partition plate, a movable partition plate, a semi-hole sleeve, and a screw lifting mechanism.

[0013] An integrated machining method for induction hardening and tempering of motorcycle crankshaft connecting rods, employing the aforementioned integrated device for induction hardening and tempering of motorcycle crankshaft connecting rods, includes the following steps. The crankshaft connecting rod, whose size and shape need to be processed, is adjusted by the area adjustment component to adjust the position of the rotating disks on both sides of the frame, thereby adjusting the processing area range on both sides of quenching and tempering. The rotating disk with the cooling component installed on one side corresponds to the quenching processing area, and the rotating disk on the other side corresponds to the tempering processing area. After the corresponding processing area range is adjusted, the height and position of the induction heating plate in the two processing areas are adjusted by the position adjustment component; After the height of the induction heating plate is adjusted, the rotating disk is driven to rotate by the belt rotation mechanism, and the workpiece is heated in conjunction with the movement of the induction heating plate within a specified range on the connecting frame. After heating is completed, the cooling component provided on the corresponding side of the rotating disk rapidly cools the part of the workpiece located in the quenching processing area, while the part of the workpiece located in the tempering processing area is slowly cooled by introducing air.

[0014] The integrated device and processing method for induction hardening and tempering of motorcycle crankshaft connecting rods of the present invention, in actual operation, adjusts the position of the rotating disks on both sides of the frame by means of the area adjustment component to adjust the size and shape of the crankshaft connecting rod to be processed, thereby adjusting the processing area range on both sides of the quenching and tempering. The rotating disk with the cooling component installed on one side corresponds to the quenching processing area, and the rotating disk on the other side corresponds to the tempering processing area. After the corresponding processing area range is adjusted, the height and position of the induction heating plate in the two processing areas are adjusted by means of the position adjustment component. After the height of the induction heating plate is adjusted, the rotating mechanism drives the rotating disk to rotate. The induction heating plate moves within a specified range on the connecting frame to heat the workpiece. After heating, the cooling component on the corresponding side of the rotating disk rapidly cools the part of the workpiece located in the quenching processing area. The part of the workpiece located in the tempering processing area is slowly cooled by introducing air. This allows the range of the quenching and tempering processing areas to be adjusted according to the size type of the crankshaft connecting rod to be processed, resulting in better local quenching and tempering effects during actual processing.

Detailed Implementation

[0024] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0025] In the description of this invention, it should be understood that "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] Please see Figures 1 to 6This invention provides an integrated device and processing method for induction hardening and tempering of motorcycle crankshaft connecting rods: It includes a frame 101 and a partitioned processing assembly. The partitioned processing assembly includes a rotating disk 102, a drive mechanism 103, a connecting frame 104, an induction heating plate 105, a zone adjustment component, a position adjustment component, and a cooling component. The zone adjustment component includes a side sealing plate 201, a central pressing plate 202, a moving plate 203, a pulling component 204, and a bidirectional drive component. The position adjustment component includes a mounting frame 301, an adjusting screw 302, a rotating sleeve 303, a screw drive mechanism 304, and a height adjustment component. The cooling component includes a rotating nozzle 401 and a water outlet mechanism 402. The bidirectional drive component includes a bidirectional threaded screw 501, a gear transmission mechanism 502, and a drive motor 503. The height adjustment component includes a side guide plate 6. 01. The internal gear plate 602, the adjusting gear 603, and the gear drive mechanism 604, through the aforementioned solution, solve the problem that the installation position and relative spacing of the high-frequency induction coil, low-frequency induction coil, and high-pressure water spray device in the existing technical solution are usually fixed and cannot be adjusted, or the processing area can only be changed by replacing the entire coil assembly. As a result, when the crankshaft connecting rod to be processed has different total lengths, different upper quenching zone lengths, or different lower tempering zone lengths, the device cannot flexibly and independently adjust the axial range of the quenching zone and tempering zone according to the actual size, and it is also difficult to fine-tune the coupling gap between the induction coil and the workpiece surface. This results in insufficient positional accuracy of local quenching and tempering, unclear heating and cooling boundaries when performing zoned heat treatment on connecting rods of different specifications, which seriously affects the performance consistency of the upper high hardness and wear-resistant layer and the lower high toughness layer.

[0027] Furthermore, the two rotating disks 102 are rotatably mounted on both sides of the frame 101, and two sets of rotating mechanisms 103 are connected to the two rotating disks 102 respectively to drive the corresponding rotating disks 102 to rotate. Two connecting frames 104 are fixedly installed on the inner side of each rotating disk 102. The induction heating plate 105 is arranged in a one-to-one correspondence with the connecting frame 104. The induction heating plate 105 is connected to the corresponding connecting frame 104 through the position adjustment component. The area adjustment component is connected to the connecting frame 104 to adjust the processing range size of the specified area. The position adjustment component is connected to the induction heating plate 105 to adjust the heating position of the corresponding induction heating plate 105. The cooling component is connected to one of the rotating disks 102 to quickly cool the corresponding side of the workpiece.

[0028] In this embodiment, the frame 101 mainly consists of a bottom support structure and an upper inner groove structure. The rotating disks 102 are arranged on both sides of the inner groove structure above the frame 101. The two rotating disks 102 are driven by the corresponding rotating mechanism 103. The rotating mechanism 103 mainly consists of an outer ring gear, gears, and a motor. The motor drives the gears to rotate, and then the gears and the outer ring gear cooperate to drive the corresponding rotating disks 102 to rotate.

[0029] The rotating disk 102 is provided with corresponding connecting frames 104 at both the upper and lower positions. Each connecting frame 104 is provided with a corresponding induction heating plate 105 through the position adjustment component. The left and right sides of the inner groove structure above the frame 101 correspond to the quenching and tempering processing areas. Since the quenching process requires rapid cooling, the side of the rotating disk 102 with the cooling component is the quenching processing area, and the other rotating disk 102 corresponds to the tempering processing area. The frame is provided with corresponding air inlets and air guide structures in the tempering processing area to facilitate the natural cooling of some processed parts in the subsequent tempering processing area.

[0030] In actual operation, the crankshaft connecting rod dimensions and shapes to be processed are adjusted using the area adjustment component to adjust the positions of the rotating disks 102 on both sides of the frame 101, thereby adjusting the processing area ranges on both sides of quenching and tempering. The rotating disk 102 with cooling components on one side corresponds to the quenching processing area, and the rotating disk 102 on the other side corresponds to the tempering processing area. After the corresponding processing area ranges are adjusted, the height and position of the induction heating plates 105 in the two processing areas are adjusted using the position adjustment component. After completion, the rotating mechanism 103 drives the rotating disk 102 to rotate, and the induction heating plate 105 moves within a specified range on the connecting frame 104 to heat the workpiece. After heating is completed, the cooling component set on the corresponding side of the rotating disk 102 rapidly cools the part of the workpiece located in the quenching processing area, while the part of the workpiece located in the tempering processing area is slowly cooled by introducing air. This allows the range of the quenching and tempering processing areas to be adjusted according to the size type of the crankshaft connecting rod to be processed, resulting in better local quenching and tempering effects during actual processing.

[0031] Furthermore, each of the rotating disks 102 is provided with a corresponding side sealing disk 201 on one side, and the side sealing disk 201 is slidably connected to the connecting frame 104; a transfer pressing disk 202 is rotatably mounted on the side of each side sealing disk 201; two moving plates 203 are slidably mounted on the side of each rotating disk 102 near the side sealing disk 201; the moving plate 203 is connected to the corresponding side sealing disk 201 through the pulling member 204, one side of the pulling member 204 is rotatably connected to the moving plate 203, and the other side of the pulling member 204 is rotatably connected to the side sealing disk 201; each rotating disk 102 is provided with the bidirectional driving component for driving the corresponding moving plate 203 to move.

[0032] Furthermore, the two sides of the bidirectional threaded screw 501 are threadedly connected to the corresponding two sides of the movable plate 203, and the bidirectional threaded screw 501 is rotatably mounted on the corresponding rotating disk 102; the gear transmission mechanism 502 is connected to the bidirectional threaded screw 501; the output shaft of the drive motor 503 is connected to the gear transmission mechanism 502, and the drive motor 503 is fixedly mounted on the outside of the rotating disk 102.

[0033] Furthermore, a rotating nozzle 401 is provided on the inner side of one of the side sealing discs 201; the water outlet mechanism 402 is connected to the rotating nozzle 401 and is installed on the side sealing disc 201.

[0034] In this embodiment, the shape and size of the side sealing plate 201 match the machining groove provided in the machining inner groove structure above the frame 101. The side sealing plate 201 is slidably connected to the connecting frame 104 provided corresponding to the rotating plate 102. One of the side sealing plates 201 is provided with a corresponding rotating nozzle 401 and a water outlet mechanism 402. The rotating nozzle 401 is provided with an independent driving element, which can change the water outlet range to a certain extent by rotating the nozzle. The water outlet mechanism 402 is provided with a corresponding water storage structure and a pump body to facilitate the discharge of water. The rotating nozzle 401 and the water outlet mechanism 402 are common rotating spray structures. Therefore, the basic structure of the rotating nozzle 401 will not be described in detail in this solution.

[0035] Each of the side sealing discs 201 has a central clamping disc 202 rotatably mounted on its inner axial region. The central clamping discs 202 on the two side sealing discs 201 can clamp and limit both sides of the crankshaft connecting rod to be processed, making the corresponding crankshaft connecting rod more stable during actual processing. Moreover, the rotation of the central clamping disc 202 on the corresponding side sealing disc 201 can prevent the crankshaft connecting rod from rotating with the side sealing disc 201 and the rotating disc 102. When the rotating discs 102 on both sides rotate accordingly, the central clamping disc 202, which is pressed against both sides of the crankshaft connecting rod, will maintain a stable clamping state by rotating on the corresponding side sealing disc 201. Since the rotation speed of the rotating discs 102 on both sides may be inconsistent, the rotation of the central clamping disc 202 on the corresponding side sealing disc 201 can prevent the processing part from being subjected to large torque on both sides.

[0036] The side sealing plate 201 is driven by the movable plate 203 and the pulling member 204. The movable plate 203 is driven by the bidirectional threaded screw 501. The bidirectional threaded screw 501 is connected to the output shaft of the drive motor 503 through the gear transmission mechanism 502.

[0037] The side sealing disc 201 on one side is connected to the two corresponding moving plates 203 via two pulling members 204. The two moving plates 203 are driven by the bidirectional threaded screw 501. The threads on both sides of the bidirectional threaded screw 501 have opposite directions. When the bidirectional threaded screw 501 rotates, the two corresponding moving plates 203 can be extended or brought closer together by the bidirectional threaded screw 501. Then, the corresponding movement of the two moving plates 203, in coordination with the pulling members 204, drives the side sealing disc 201 to slide on the connecting frame 104.

[0038] The sliding of the side sealing plate 201 on the connecting frame 104 can change the actual processing range of the corresponding processing area, so that the size of the corresponding processing area can be matched with the original part to be processed as much as possible during heating.

[0039] Furthermore, each of the connecting frames 104 is slidably mounted with a mounting box frame 301; the adjusting screw 302 is configured one-to-one with the mounting box frame 301, the adjusting screw 302 is threadedly connected to the corresponding mounting box frame 301, and is rotatably mounted on the connecting frame 104; the rotating hole sleeve 303 is configured one-to-one with the adjusting screw 302, the rotating hole sleeve 303 is threadedly connected to the adjusting screw 302, and is rotatably mounted on the side sealing plate 201; the screw-driven rotation mechanism 304 is connected to the adjusting screw 302 and is mounted on the outside of the rotating disk 102, for driving the two adjusting screws 302 on a designated side to rotate.

[0040] Furthermore, the side guide plate 601 is fixedly connected to the induction heating plate 105 and slidably mounted on the mounting frame 301; the internal gear plate 602 is fixedly connected to the induction heating plate 105 and slidably mounted on the mounting frame 301; the adjusting gear 603 meshes with the internal gear platform provided on the internal gear plate 602, and the adjusting gear 603 is rotatably mounted on the mounting frame 301; the gear drive mechanism 604 is connected to the adjusting gear 603, and the gear drive mechanism 604 is fixedly mounted inside the mounting frame 301.

[0041] In this embodiment, the mounting box 301 on the connecting frame 104 is driven by the corresponding adjusting screw 302. Each side sealing plate 201 is also rotatably provided with a corresponding rotating hole sleeve 303 to cooperate with the corresponding adjusting screw 302, so that the movement of the side sealing plate 201 and the rotation of the adjusting screw 302 do not interfere with each other.

[0042] The lead screw drive mechanism 304 is mainly composed of a corresponding gear set, a gear chain, and a motor. The gear set and the gear chain enable the two adjusting lead screws 302 on the corresponding side to rotate synchronously. Then, the corresponding motor, in conjunction with the gear set and the gear chain, completes the synchronous drive of the two adjusting lead screws 302.

[0043] Each mounting bracket 301 has corresponding guide sleeves on both sides, which respectively cooperate with the side guide plate 601 and the internal gear plate 602. The gears on the internal gear plate 602 cooperate with the adjusting gears 603 provided inside the mounting bracket 301. The adjusting gears 603 are driven by the gear drive mechanism 604. The gear drive mechanism 604 mainly consists of a gear chain drive structure and a motor, so that the internal gear plate 602 can be moved up and down by the gear drive mechanism 604 and the adjusting gears 603, thereby adjusting the mating height of the induction heating plate 105.

[0044] Preferably, the partition processing assembly provided by the present invention further includes a lifting frame 701, a side-shifting bracket 702, a packaging plate 703, and a partition component. The partition component includes a fixed partition plate 801, a movable partition plate 802, a half-hole sleeve 803, and a lead screw lifting mechanism 804. The partition processing assembly further includes a lead screw lifting mechanism 704 and a lead screw side-shifting mechanism 705.

[0045] Furthermore, the lifting frame 701 is slidably mounted on the top of the frame 101; the side-shifting bracket 702 is slidably mounted on one side of the lifting frame 701; the encapsulation plate 703 is fixedly mounted on the side-shifting bracket 702; and the partition member is connected to the frame 101 to separate the two processing areas of quenching and tempering.

[0046] Furthermore, the lead screw lifting mechanism 704 is connected to the lifting frame 701 and is used to drive the lifting frame 701 to move; the lead screw lateral movement mechanism 705 is connected to the lateral movement bracket 702 and is used to drive the lateral movement bracket 702 to move.

[0047] In this embodiment, the lifting frame 701 cooperates with the corresponding connecting frame 104 provided on the top of the frame 101. The side-shifting bracket 702 is slidably installed on the lifting frame 701. The lifting frame 701 and the side-shifting bracket 702 are driven by the lead screw lifting mechanism 704 and the lead screw side-shifting mechanism 705, respectively. The lead screw lifting mechanism 704 and the lead screw side-shifting mechanism 705 are both composed of corresponding lead screws and motors. The motor drives the corresponding lead screw to rotate, thereby realizing the driving of the corresponding frame.

[0048] The packaging plate 703 is fixedly installed on the lateral shift bracket 702. The packaging plate 703 is provided with a corresponding semi-circular groove. The packaging plate 703 can cooperate with the inner groove structure above the frame 101 to form a closed cylindrical groove processing range. Then, the position and height of the packaging plate 703 can be adjusted by the lateral shift of the lateral shift bracket 702 and the vertical movement of the lifting frame 701, so that the external environment can be avoided from affecting the internal processing area during actual processing.

[0049] Furthermore, the fixed isolation plate 801 is fixedly installed inside the frame 101; the movable isolation plate 802 is slidably installed on the side of the frame 101 near the fixed isolation plate 801; both the fixed isolation plate 801 and the movable isolation plate 802 are equipped with the semi-hole sleeve 803; the screw lifting mechanism 804 is connected to the movable isolation plate 802 and is used to drive the movable isolation plate 802 to move up and down.

[0050] In this embodiment, the fixed isolation plate 801 and the movable isolation plate 802 form a corresponding separation structure. The semi-hole sleeve 803 is bolted to the fixed isolation plate 801 and the movable isolation plate 802. The semi-hole sleeve 803 can be replaced and adjusted according to the actual size and shape of the crankshaft connecting rod being processed. The semi-hole sleeve 803, which is provided in cooperation with the fixed isolation plate 801 and the movable isolation plate 802, can more effectively isolate and cut the quenched end and the tempered end of the crankshaft connecting rod, avoid mutual interference between the corresponding processing areas of quenching and tempering, and ensure the stability of the two corresponding processing areas.

[0051] The movable isolation plate 802 is driven by the lead screw lifting mechanism 804, which mainly consists of a lead screw and a motor. The movable isolation plate 802 moves up and down to clamp and limit the crankshaft connecting rod that has completed feeding, and at the same time, it can separate two different processing areas. When the fixed isolation plate 801 and the movable isolation plate 802 clamp and limit the processing original part's separation area through the corresponding semi-hole sleeve 803, the two sides of the processing original part can maintain relative rotation with the side sealing plates 201 on both sides through the intermediate pressure plate 202, so that the processing original part will not be affected by the rotation of the side sealing plates 201 on both sides during actual processing.

[0052] The encapsulation plate 703 is provided with corresponding vertical grooves to cooperate with the barrier structure formed by the movable isolation plate 802 and the fixed isolation plate 801.

[0053] Please see Figure 7 An integrated machining method for induction hardening and tempering of motorcycle crankshaft connecting rods, employing the integrated induction hardening and tempering device for motorcycle crankshaft connecting rods as described, includes the following steps. S1: The size and shape of the crankshaft connecting rod to be processed as needed are adjusted by adjusting the position of the rotating disks 102 on both sides of the area adjustment component frame 101, thereby adjusting the processing area range on both sides of quenching and tempering. The rotating disk 102 with cooling components installed on one side is the quenching processing area, and the rotating disk 102 on the other side is the tempering processing area. S2: After the corresponding processing area range is adjusted, the height and position of the induction heating plate 105 in the two processing areas are adjusted by the position adjustment component; S3: After the height position of the induction heating plate 105 is adjusted, the rotating disk 102 is driven to rotate by the rotating mechanism 103, and the workpiece is heated in conjunction with the movement of the induction heating plate 105 within a specified range on the connecting frame 104. S4: After heating is completed, the cooling component provided on the corresponding side of the rotating disk 102 rapidly cools the part of the workpiece located in the quenching processing area, while the part of the workpiece located in the tempering processing area is slowly cooled by introducing air.
