Description

Technical Field

[0001] The invention relates to the field of diesel engine camshaft processing, and in particular to a continuous through-type quenching and conveying device for a diesel engine camshaft. Background Art

[0002] The diesel engine camshaft is the core component of the diesel engine valve system. The diesel engine camshaft needs to be quenched during production and processing. At present, in order to improve the diesel engine camshaft quenching processing equipment, a quenching conveying device is usually used to convey the diesel engine camshaft, and the diesel engine camshaft is quenched during the transportation process.

[0003] Publication No. CN114561521B proposes a high-frequency quenching device and quenching process for a motor shaft. The device clamps the shaft to be quenched on a conveyor belt through the cooperation of a power unit, a support assembly, a clamping assembly, and a locking assembly, and quenches it through a high-frequency sensor and a water pipe. After quenching, it returns to the conveyor belt for further transportation. This operation method, which requires repeated clamping, transfer, and resetting, has low work efficiency and significantly reduces production efficiency. In addition, during the quenching process, due to the cam structure on the outer wall of the diesel engine camshaft, when a traditional induction coil is used to quench the cam position, the difference in the spacing between the cam lobe tip and the base circle part and the induction coil will cause the cam lobe tip to have a temperature that is too high and the base circle part to have a temperature that is too low, affecting the quenching quality. For this reason, we propose a continuous through-type quenching and conveying device for diesel engine camshafts. Summary of the Invention

[0004] The purpose of the present invention is to provide a continuous quenching and conveying device for a diesel engine camshaft, which solves the technical problem that the existing quenching and conveying device adopts a repeated clamping, transferring and resetting operation mode, which has low working efficiency and significantly reduces production efficiency.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions: A continuous through-type quenching and conveying device for a diesel engine camshaft is used to convey a diesel engine camshaft body. The quenching and conveying device comprises: a conveying mechanism 1, and a plurality of camshaft fixing mechanisms provided on the conveying mechanism 1 for fixing the diesel engine camshaft body, and a plurality of quenching mechanisms for quenching the diesel engine camshaft body; Among them, the quenching mechanism includes a carrier connected to a conveying mechanism, a driving device arranged on the carrier, and a split induction coil connected to the driving device. When the split induction coil corresponds to a diesel engine camshaft body on a camshaft fixing mechanism, it is driven by the driving device to move along the axis direction of the corresponding diesel engine camshaft body. The split induction coil includes two groups of symmetrically arranged arc coils, and a driving part for driving the two arc coils to move toward or away from each other.

[0006] A further improvement is that the driving part includes a bearing seat, a bidirectional screw rotatably arranged in the bearing seat, a rotating device arranged on one side of the bearing seat and connected to the bidirectional screw, and sliders respectively threadedly mounted on both ends of the outer wall of the bidirectional screw, and the two groups of sliders are respectively connected to the two arc coils.

[0007] A further improvement is that a water spray channel is provided in the arc coil, a plurality of liquid spray holes connected to the water spray channel are provided on the inner wall of the arc coil, and a connecting pipe connected to the water spray channel is provided on the outer wall of the arc coil.

[0008] A further improvement is that the camshaft fixing mechanism includes two groups of mounting frames symmetrically arranged on the conveying mechanism, a fixed sleeve arranged on the mounting frame, a movable rod inserted at one end of the fixed sleeve, and a clamping sleeve arranged at one end of the movable rod for engaging with the end of the diesel engine camshaft body, and an elastic member is provided between the movable rod and the fixed sleeve.

[0009] A further improvement is that one end of the movable rod located in the fixed sleeve is connected to one end of a pull rope, and the other end of the pull rope is movable through the mounting frame and is connected to a permanent magnet block, the permanent magnet block is vertically slidably arranged on the outer wall of the mounting frame away from the fixed sleeve, and the permanent magnet block is also connected to the mounting frame through a second elastic member, and a conveying mechanism 2 is arranged below the conveying mechanism 1 at a parallel interval, and its input end corresponds to the output end position of the conveying mechanism 1, and an electromagnetic block is provided on the conveying mechanism 1 and near its output end; When the conveying mechanism 1 transports the camshaft fixing mechanism to a preset position above the conveying mechanism 2, the electromagnetic block is energized to attract the permanent magnet block in the camshaft fixing mechanism, and then the movable rod is pulled by the pull rope to drive the clamping sleeve to separate from the diesel engine camshaft body, so that the diesel engine camshaft body falls onto the conveying mechanism 2.

[0010] A further improvement is that the split induction coil is coaxial with the corresponding diesel engine camshaft body, a mounting plate is provided on the bearing seat, and the mounting plate is connected to the output end of the driving device through a telescopic device. The quenching conveying device also includes a detection part, which is configured to detect the highest point position of the cam on the outer wall of the diesel engine camshaft body, and after detecting that the highest point position of the cam is facing upward, the telescopic device is controlled to drive the split induction coil to move upward to a preset height.

[0011] A further improvement is that the detection portion includes a visual detection device provided on a side of the mounting plate facing a center of the conveying mechanism for detecting a cam on an outer wall of the diesel engine camshaft body, and a position detection device for detecting the highest point position of the cam; the carrier is provided with a rotating device, the output end of the rotating device is provided with a driving gear, and the outer wall of the fixed sleeve is provided with a driven gear for meshing with the driven gear; The visual detection device, position detection device and rotation device are all electrically connected to the controller.

When the position detection device detects the highest point of the cam, the external controller controls the rotation device to close, and the telescopic device drives the split induction coil to move upward to a preset height.

[0012] A further improvement is that the detection part also includes a high-temperature resistant protective shell arranged on one side of the mounting plate and sleeved on the outside of the visual detection equipment and the position detection equipment. The bottom of the high-temperature resistant protective shell is hollow so that the detection ends of the visual detection equipment and the position detection equipment can extend out of its bottom.

[0013] The beneficial effects of the present invention are: The present invention continuously conveys the diesel engine camshaft body fixed on the camshaft fixing mechanism to the quenching mechanism through a conveying mechanism. The split induction coil in the quenching mechanism realizes the precise opening and closing action of the two arc-shaped coils under the control of the driving unit, so that the split induction coil moves from one end of the camshaft fixing mechanism to the outer wall of the diesel engine camshaft body or detaches from one end of the camshaft fixing mechanism. The split induction coil is driven by the driving device to move axially along the diesel engine camshaft body to perform quenching work, without the need to repeatedly clamp, transfer and reset the diesel engine camshaft body, greatly improving the efficiency of the diesel engine camshaft body quenching treatment and improving production efficiency. In addition, in conjunction with visual detection equipment, position detection equipment and rotating equipment, dynamic adjustment of the distance between the split induction coil and the cam profile of the outer wall of the diesel engine camshaft body is realized, effectively reducing the problem of overheating of the cam lobe tip and insufficient heating of the cam base circle, improving the uniformity of cam position heating, and ensuring the quenching quality of the diesel engine camshaft body.

DETAILED DESCRIPTION

[0016] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0017] Example 1 Please see the attached Figure 1-4 A continuous through-type quenching conveying device for a diesel engine camshaft is used to convey a diesel engine camshaft body 100. The diesel engine camshaft body 100 is a conventional component in the art, including a shaft portion and a plurality of cams arranged on the outer wall of the shaft portion, etc., which will not be described in detail herein. The quenching conveying device comprises: a conveying mechanism 200 (including the following parts: a driving unit, a transmission component, a conveying carrier and a supporting frame, etc., and the conveying mechanism 200 preferably adopts a chain plate conveyor widely used in the field, etc.), and a plurality of camshaft fixing mechanisms 400 arranged on the conveying mechanism 200 for fixing the diesel engine camshaft body 100, and a plurality of quenching mechanisms 500 for quenching the diesel engine camshaft body 100. Figure 1 It can be seen that a plurality of camshaft fixing mechanisms 400 are arranged at equal intervals along the conveying direction of the conveying mechanism 200 on the conveying carrier of the conveying mechanism 200 and are transported by the conveying mechanism 200. A plurality of quenching mechanisms 500 are arranged at equal intervals along the conveying direction of the conveying mechanism 200 on the support frame of the conveying mechanism 200. When in use, the diesel engine camshaft body 100 to be quenched is fixed by the camshaft fixing mechanism 400, and the conveying mechanism 200 conveys the diesel engine camshaft body 100 to be quenched to the quenching mechanism 500 and then stops. After the diesel engine camshaft body 100 is quenched by the quenching mechanism 500, the conveying mechanism 200 continues to work. By setting up several groups of quenching mechanisms 500 (such as the attached Figure 1 There are three groups shown) that can simultaneously quench multiple diesel engine camshaft bodies 100, thereby improving work efficiency; The quenching mechanism 500 includes a carrier 501 connected to the conveying mechanism 200, a driving device 502 provided on the carrier 501, and a split induction coil 505 connected to the driving device 502. The carrier 501 has an L-shaped vertical section, which is connected to the support frame in the conveying mechanism 200. The driving device 502 can be provided on the outer wall of the horizontal section of the carrier 501, as shown in the attached figure. Figure 2 As shown, the driving device 502 of this embodiment can adopt a structure such as a motor, a reciprocating screw, and a threaded block, of course, it is not limited to this structure and will not be described in detail here. When the split induction coil 505 corresponds to the diesel engine camshaft body 100 on a camshaft fixing mechanism 400, it is driven by the driving device 502 to move along the axis direction of the corresponding diesel engine camshaft body 100. When the split induction coil 505 corresponds to the diesel engine camshaft body 100 on a camshaft fixing mechanism 400, the split induction coil 505 and the corresponding diesel engine camshaft body 100 are on the same axis. Then, the split induction coil 505 can be moved from one end of the camshaft fixing mechanism 400 to the outside of the diesel engine camshaft body 100 by the driving device 502, and the diesel engine camshaft body 100 is quenched by the split induction coil 505. The split induction coil 505 includes two sets of symmetrically arranged arc coils 5051 and a driving unit for driving the two arc coils 5051 to move toward or away from each other. The split induction coil 505 is widely used in this field. For example, one end of one arc coil 5051 is connected to the positive wiring copper bar, and one end of the other arc coil 5051 is connected to the negative wiring copper bar, as disclosed in the prior art such as publication number CN220999708U, and will not be described in detail here. The driving unit can make the two arc coils 5051 contact each other to form an annular coil with a diameter larger than the diameter of the diesel engine camshaft body 100. The annular coil moves along the axis of the diesel engine camshaft body 100 under the drive of the driving device 502, and the annular coil is energized to heat the diesel engine camshaft body 100.

[0018] Preferably, the driving portion of this embodiment includes a bearing seat 5053, the length direction of the bearing seat 5053 is parallel to the conveying direction of the conveying mechanism 200, a bidirectional screw 5054 arranged in the bearing seat 5053 is rotated through a bearing, a rotating device 5055 (such as a servo motor and a reducer) is arranged on one side of the bearing seat 5053 and connected to the bidirectional screw 5054, and sliders are respectively threadedly sleeved on both ends of the outer wall of the bidirectional screw 5054, and the two sets of sliders are respectively connected to the two arc coils 5051, as shown in the attached figure. Figure 1 As shown, the split induction coil 505 is initially located at one end of the camshaft fixing mechanism 400. The rotating device 5055 drives the bidirectional lead screw 5054 to rotate, so that the two sets of sliders move away from each other, and then the two arc coils 5051 are opened. Then the driving device 502 drives the split induction coil 505 to move, so that the two arc coils 5051 pass through one end of the camshaft fixing mechanism 400 and move to the outside of the diesel engine camshaft body 100. The bidirectional lead screw 5054 is then driven by the rotating device 5055 to rotate in the opposite direction, so that the two arc coils 5051 merge into a ring shape, and then are driven to move by the driving device 502. Similarly, after the quenching is completed, the above method is also used to make the split induction coil 505 detach from the camshaft fixing mechanism 400 and reset, which is not described in detail here.

[0019] Preferably, a water spray channel (not shown in the figure) is provided in the arc coil 5051 of this embodiment, and a plurality of groups of liquid spray holes 5052 connected to the water spray channel are provided on the inner wall of the arc coil 5051. A connecting pipe connected to the water spray channel is provided on the outer wall of the arc coil 5051. The connecting pipe is used to connect to an external water supply device. When the two arc coils 5051 are combined to heat the diesel engine camshaft body 100, the external water supply device supplies quenching liquid, which can cool and quench the diesel engine camshaft body 100 while heating, thereby meeting the continuous processing requirements.

[0020] Please see the attached Figure 5-6Preferably, the camshaft fixing mechanism 400 of this embodiment includes two sets of mounting frames 401 symmetrically arranged on the conveying mechanism 200. The two sets of mounting frames 401 are distributed along the width direction of the conveying mechanism 200. The fixed sleeves 402 are arranged on the mounting frames 401. The fixed sleeves 402 are rotatably arranged on the outer wall of the mounting frame 401 on one side facing the center of the conveying mechanism 200 using a bearing. The movable rod 403 is inserted into one end of the fixed sleeve 402. The movable rod 403 and the fixed sleeve 402 are preferably connected by sliding blocks and sliding grooves so that the two can rotate synchronously. 03 can move axially relative to the fixed sleeve 402, and is provided at one end of the movable rod 403 for engaging with the clamping sleeve 404 arranged on the end of the diesel engine camshaft body 100. The clamping sleeve 404 is, for example, a cylinder with rubber bumps on the inner wall. One end of the diesel engine camshaft body 100 can be clamped by the clamping sleeve 404, so that the diesel engine camshaft body 100 can be driven to rotate by the clamping sleeve 404. An elastic member 408 (such as a spring, etc.) is provided between the movable rod 403 and the fixed sleeve 402 so that the two clamping sleeves 404 can cooperate to clamp and position the diesel engine camshaft body 100.

[0021] As a preference, one end of the movable rod 403 of this embodiment is located in the fixed sleeve 402 and is connected to one end of a pull rope 405. One end of the pull rope 405 can be rotatably connected to one end of the movable rod 403 by a pull rope connector. The other end of the pull rope 405 is movably connected to the permanent magnet block 406 after passing through the mounting frame 401. The permanent magnet block 406 is vertically slidably arranged on the outer wall of the mounting frame 401 away from the fixed sleeve 402. The permanent magnet block 406 is also connected to the mounting frame 401 through an elastic member 409 (such as a spring, etc.) to attach Figure 5 As shown, the outer walls of the mounting frame 401 on the upper and lower sides of the permanent magnet block 406 are integrally formed with protrusions. One end of the second elastic member 409 is connected to the top protrusion, and the other end is connected to the permanent magnet block 406. A second conveying mechanism 300 (using the same equipment as the conveying mechanism 200) is arranged parallel to and spaced apart from the conveying mechanism 200. Its input end corresponds to the output end of the conveying mechanism 200. An electromagnetic block 410 is provided on the conveying mechanism 200 and near its output end. The electromagnetic block 410 is specifically arranged on the outer wall of the support frame of the conveying mechanism 200. When the conveying mechanism 1 200 conveys the camshaft fixing mechanism 400 to a preset position above the conveying mechanism 2 300 , the electromagnetic block 410 corresponds to the permanent magnet block 406 in the camshaft fixing mechanism 400 , thereby opening the electromagnetic block 410 . The electromagnetic block 410 is energized to attract the permanent magnet block 406 in the camshaft fixing mechanism 400 . The permanent magnet block 406 moves toward the electromagnetic block 410 , and then the movable rod 403 is pulled by the pull rope 405 to drive the clamping sleeve 404 to separate from the diesel engine camshaft body 100 . Under the action of gravity, the diesel engine camshaft body 100 falls on the conveying mechanism 2 300 and is conveyed to the next process by the conveying mechanism 2 300 . It should be noted that, because the two sides of the diesel engine camshaft body 100 are retracted and separated synchronously, the clamping sleeve 404 can be better separated from the diesel engine camshaft body 100 . In actual situations, a detection sensor (such as a photoelectric sensor, etc.) can also be set at the corresponding position of the outer wall of the support frame of the conveying mechanism 200. When the photoelectric sensor detects that the conveying mechanism 200 conveys a camshaft fixing mechanism 400 to a preset position, a control signal is sent to the external controller to control the electromagnetic block 410 to be energized and turned on, thereby realizing automatic unloading of the quenched diesel engine camshaft body 100.

[0022] Preferably, the split induction coil 505 of this embodiment is coaxial with the corresponding diesel engine camshaft body 100, and a mounting plate 504 is provided on the bearing seat 5053. The mounting plate 504 is connected to the output end of the driving device 502 through a telescopic device 503 (such as an electric telescopic rod, etc.). The quenching conveying device also includes a detection unit, which is configured to detect the highest point position of the cam on the outer wall of the diesel engine camshaft body 100 (i.e., the lobe tip), and after detecting that the highest point position of the cam is facing upward, the telescopic device 503 is controlled to drive the split induction coil 505 upward to a preset height. Through this arrangement, the distance between the coil and the cam profile is dynamically adjusted. The distance effectively solves the problem of overheating of the cam lobe tip and insufficient heating of the cam base circle caused by the traditional fixed coil, and improves the uniformity of heating at the cam position. The user can pre-set the above-mentioned preset height according to the size of the cam. For example, when the split induction coil 505 and the diesel engine camshaft body 100 are on the same axis, after the highest point of the cam is facing upward, the distance between the highest point of the cam and the top inner wall of the split induction coil 505 is 5 cm, and the distance between the bottom position of the cam and the bottom inner wall of the split induction coil 505 is 9 cm. In this case, the telescopic device 503 only needs to drive the split induction coil 505 to move upward by 2 cm.

[0023] Preferably, the detection portion of this embodiment includes a visual detection device 506 for detecting the cam on the outer wall of the diesel engine camshaft body 100, which is located on the side of the mounting plate 504 facing the center of the conveying mechanism 200, and a position detection device 507 for detecting the highest point position of the cam. The visual detection device 506 is a conventional device in this field and will not be described in detail here. The position detection device 507 can adopt a laser ranging sensor, etc. A rotating device 509 (such as a motor and a reducer) is provided on the carrier 501, and a driving gear 510 is provided at the output end of the rotating device 509. A fixed sleeve 402 is provided on the outer wall with a The driven gear 407 is engaged with the gear 407, and the camshaft fixing mechanism 400 is conveyed along with the conveying mechanism 200. When the camshaft fixing mechanism 400 is aligned with the quenching mechanism 500, the driven gear 407 in the camshaft fixing mechanism 400 is aligned with the driving gear 510, so that the rotating device 509 can be opened. The rotating device 509 drives the diesel engine camshaft body 100 to rotate through the driving gear 510 and the driven gear 407, so that the cam lobe on the outer wall of the diesel engine camshaft body 100 faces upward and corresponds to the laser distance sensor. At this time, the laser distance sensor detects whether the highest point of the cam is facing upward. The visual detection device 506, the position detection device 507, and the rotating device 509 are all electrically connected to the controller. When the visual detection device 506 detects the cam, the controller controls the position detection device 507 and the rotating device 509 to open. When the position detection device 507 detects the highest point of the cam, the controller controls the rotating device 509 to close, and the telescopic device 503 drives the split induction coil 505 to move upward to a preset height. For example, when the split induction coil 505 moves along the axial direction of the diesel engine camshaft body 100 on the outer wall of the diesel engine camshaft body 100, the visual detection device 506 (such as an industrial camera, etc.) collects image data of the corresponding position of the outer wall of the diesel engine camshaft body 100 and sends it to the controller. The controller compares the collected image data with the cam data pre-stored in the database. When it is determined to be a cam, the external controller controls the position detection device 507 to start position detection and the rotating device 509 to turn on (of course, the driving device 502 can also be electrically connected to the controller. When it is determined to be a cam, the controller also controls the driving device 502 to turn off, so that the split induction coil 50 5 stops moving); the rotating device 509 is turned on to rotate the diesel engine camshaft body 100. When the position detection device 507 detects the highest point of the cam at the corresponding position, it sends a signal to the controller, and the controller controls the rotating device 509 to be closed. At this time, the highest point of the cam is toward the position detection device 507 (i.e., upward), and the controller controls the telescopic device 503 to drive the split induction coil 505 to move upward to a preset height (preferably, the controller also has a built-in timing module. After the control driving device 502 is closed for a preset time, the control driving device 502 is automatically turned on to continue to drive the split induction coil 505 to move axially along the diesel engine camshaft body 100).

[0024] Preferably, the detection part of this embodiment also includes a high-temperature resistant protective shell 508 arranged on one side of the mounting plate 504 and sleeved on the outside of the visual detection device 506 and the position detection device 507. The shell is made of high-temperature resistant material (such as polyvinylidene fluoride, austenitic stainless steel, etc.) to protect the internal equipment from temperature damage caused by the split induction coil 505. The bottom of the high-temperature resistant protective shell 508 is hollow so that the detection ends of the visual detection device 506 and the position detection device 507 can extend out of its bottom.

[0025] The above embodiments merely illustrate several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
