Description

Technical Field

[0001] The present invention relates to the technical field of spring manufacturing, and particularly relates to a conveying production line for spring manufacturing. Background Art

[0002] A spring is a mechanical part that utilizes elasticity. A part made of elastic material deforms under the action of an external force and returns to its original state after the external force is removed;

[0003] After the spring is manufactured, it needs to be conveyed to the detection point by a conveying line. Before conveying, the processing personnel need to grind the two ends of the spring to facilitate the subsequent installation of the spring. After the spring is conveyed to the detection point, the detection personnel need to detect the surface quality, high-temperature resistance performance and other characteristics of the spring. The existing conveying line cannot play a detection role for some items of the spring during the conveying process, and only has a single conveying function, so it is impossible to screen out some unqualified springs before the detection process starts and reduce the workload of subsequent spring detection. Moreover, the spring conveying line cannot grind the two ends of the spring during the conveying process of the spring, so it is impossible to reduce the pretreatment work of the spring before conveying. Therefore, a conveying production line for spring manufacturing is proposed to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems that the spring conveying line in the prior art cannot detect some characteristics of the spring and cannot grind the two ends of the spring, and to propose a conveying production line for spring manufacturing.

[0005] In order to achieve the above purpose, the present invention adopts the following technical scheme:

[0006] A conveying production line for spring manufacturing includes a conveying disk that plays a role in rotary conveying and a bearing assembly for placing springs. The bearing assembly includes a plurality of bases circumferentially distributed on the top end of the conveying disk and a compression plate arranged above the bases. A spring insertion post is fixedly connected to the top end of the base, a lower grinding disk is fixedly connected to the top end of the base, two symmetrically arranged lifting lead screws are rotatably arranged inside the base, a lifting motor connected to the lifting lead screw is installed at the bottom end of the base, a threaded through hole threadedly connected to the lifting lead screw is opened inside the compression plate, a rotation opening is opened at the center of the compression plate, a rotation groove body is rotatably connected to the inner side of the rotation opening, a plurality of moving through grooves distributed in a circle are opened at the bottom end of the rotation groove body, an inner support assembly is arranged inside the moving through groove, and a rotation gear ring is fixedly connected to the outer side wall of the rotation groove body;

[0007] A lifting ring is arranged between the base and the compression plate. A guide block sleeved on the surface of the lifting screw rod is fixedly connected to the side wall of the lifting ring. An electromagnetic induction heating coil for heating the spring is arranged inside the lifting ring.

[0008] An annular groove is opened at the bottom end of the compression plate. A detection type pressure sensor is installed on the inner wall of the annular groove. A pressure bearing ring moving up and down is slidably connected to the inner wall of the annular groove. An upper grinding disc is fixedly connected to the bottom end of the pressure bearing ring. The bottom end of the lifting ring is connected with a visual inspection ring through an L-shaped rod.

[0009] Preferably, an indicator light is arranged at the top end of the conveying disc near the base. A rotating column is fixedly connected to the bottom end of the conveying disc. A support seat is rotatably arranged at the bottom end of the rotating column. A conveying tooth ring is fixedly connected to the surface of the rotating column. A conveying motor is installed at the top end of the support seat. A conveying gear meshing with the conveying tooth ring is fixedly connected to the output end of the conveying motor.

[0010] Preferably, a groove is opened at the top end of the base. An opposed photoelectric sensor for measuring the lifting distance of the compression plate is installed inside the groove.

[0011] Preferably, inner holes distributed in a circumferential manner are opened on the inner wall of the visual inspection ring. High-temperature resistant cameras are installed inside the inner holes.

[0012] Preferably, a rotating motor is installed at the top end of the compression plate. A rotating gear meshing with the rotating tooth ring is fixedly connected to the output end of the rotating motor.

[0013] Preferably, the inner support assembly includes an electric push rod installed on the inner wall of the moving through groove and an inner support rod slidably connected inside the moving through groove. One end of the electric push rod is fixedly connected to the inner support rod. Inner support blocks are fixedly connected to the side walls of the inner support rod.

[0014] Preferably, mounting grooves are opened on both sides of the inner support block. Avoidance type pressure sensors are installed on the inner walls of the mounting grooves. Protrusions are slidably arranged inside the mounting grooves.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. In this solution, by arranging a conveying disc, an inner support assembly and a visual inspection ring, and utilizing the rotation of the spring, the visual inspection ring can spiral upward along the surface of the spring, so as to realize the comprehensive detection function of the surface quality of the spring during the conveying process, without the need for staff to visually inspect, significantly improving the detection efficiency and reducing the workload of the staff.

[0017] 2. In this solution, by providing a conveying tray, a rotating motor, a rotating trough, an upper grinding disc and a lower grinding disc, the two ends of the spring can be ground flat during the spring conveying process, so that workers do not need to use grinding tools to grind the spring, reducing the pre-treatment operation before spring conveying and indirectly improving the spring conveying efficiency.

[0018] 3. In this solution, by providing a conveying tray, a lifting motor, an opposed photoelectric sensor, a lifting ring and a compression plate, the spring is heated by the electromagnetic induction heating coil inside the lifting ring, the compression plate is driven by the lifting motor to move downward to compress the spring, and then the compression plate moves upward until the spring returns to its original position. By comparing whether the upward and downward movement distances of the compression plate are the same, it is judged whether the spring can be normally reset after being compressed after heating, realizing the detection function of the high-temperature resistance performance of the spring.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0031] Example, refer to Figures 1 to 8, A conveying production line for spring manufacturing, including a conveying disk 1 that plays a role in rotary conveying and a bearing assembly for placing springs. The bearing assembly includes a plurality of bases 2 circumferentially distributed at the top of the conveying disk 1 and a compression plate 4 arranged above the bases 2. The downward movement of the compression plate 4 can compress the conveyed springs, facilitating the compression of the springs; a spring insertion post 12 is fixedly connected to the top of the base 2, and the placed spring is inserted on the spring insertion post 12, facilitating the temporary limiting of the spring.

[0032] A lower grinding disk 13 is fixedly connected to the top of the base 2. Two symmetrically arranged lifting lead screws 10 are rotatably arranged inside the base 2. A lifting motor 9 connected to the lifting lead screw 10 is installed at the bottom of the base 2. A threaded through hole threadedly connected to the lifting lead screw 10 is opened inside the compression plate 4.

[0033] It should be noted that: the lifting motor 9 drives the lifting lead screw 10 to rotate. Under the cooperation of the threaded through hole inside the compression plate 4 and the lifting lead screw 10, the lifting of the compression plate 4 is controlled, and the conveyed spring can be compressed.

[0034] A rotation port is opened at the center of the compression plate 4. A rotation groove body 6 is rotatably connected to the inner side of the rotation port. A plurality of moving through grooves 601 distributed in a circle are opened at the bottom of the rotation groove body 6. An inner support assembly is arranged inside the moving through grooves 601. Further, the inner support assembly includes an electric push rod 19 installed on the inner wall of the moving through groove 601 and an inner support rod 20 slidably connected inside the moving through groove 601. One end of the electric push rod 19 is fixedly connected to the inner support rod 20, and an inner support block 21 is fixedly connected to the side wall of the inner support rod 20.

[0035] It should be noted that: the electric push rod 19 is used to drive the inner support rod 20 inside the moving through groove 601 to move, and then drive the inner support block 21 to move, so that the inner support block 21 can squeeze the inside of the spring, realizing the support and fixation of the spring.

[0036] A lifting ring 3 is arranged between the base 2 and the compression plate 4. A guide block sleeved on the surface of the lifting lead screw 10 is fixedly connected to the side wall of the lifting ring 3. An electromagnetic induction heating coil 29 for heating the spring is arranged inside the lifting ring 3. The bottom end of the lifting ring 3 is connected to a visual inspection ring 5 through an L-shaped rod. Further, a plurality of inner holes distributed in a circle are opened on the inner wall of the visual inspection ring 5, and a high-temperature resistant camera 18 is installed inside the inner holes.

[0037] It should be noted that: when the spring is inserted on the spring insertion post 12, the bottom end of the spring also penetrates through the visual inspection ring 5. When the spring rotates, the visual inspection ring 5 spirally moves upward along the surface of the spring, and then drives the lifting ring 3 to move upward through the L-shaped rod. During this process, the electromagnetic induction heating coil 29 performs electromagnetic induction heating on the spring, preparing for the high-temperature resistant performance detection of the spring.

[0038] It should be noted that when the visual inspection ring 5 moves spirally upward along the surface of the spring, the camera on the inner wall of the visual inspection ring 5 can take pictures of the spring surface and transmit the image information to the controller. If the controller recognizes that there are defects (such as cracks and burrs) on the spring surface in the transmitted image information, the controller controls the indicator light 11 to emit light and will not perform subsequent detection operations.

[0039] An annular groove 401 is opened at the bottom end of the compression plate 4. A detection type pressure sensor 17 is installed on the inner wall of the annular groove 401. A pressure-bearing ring 16 that moves up and down is slidably connected to the inner wall of the annular groove 401. The bottom end of the pressure-bearing ring 16 is fixedly connected to an upper grinding disc 15. Further, a groove is opened at the top end of the base 2, and an opposed photoelectric sensor 14 for measuring the lifting distance of the compression plate 4 is installed inside the groove.

[0040] It should be noted that when the compression plate 4 compresses the heated spring, the spring will in turn squeeze the upper grinding disc 15, and then squeeze the detection type pressure sensor 17 through the pressure-bearing ring 16. The detection type pressure sensor 17 can detect the elastic force value when the spring is compressed by a certain distance. When the compression plate 4 resets, when several detection type pressure sensors 17 monitor that the elastic force value is zero, it means that the spring has reset. At this time, if the downward movement distance of the compression plate 4 measured by the opposed photoelectric sensor 14 is the same as the upward movement distance, it means that the length of the spring after reset is the same as that before compression, then the high-temperature resistance performance of the spring is qualified; otherwise, it means that the high-temperature resistance performance of the spring is unqualified.

[0041] Further, an indicator light 11 is provided at the top end of the conveying disc 1 near the base 2. When the indicator light 11 is on, it means that the spring at this place is unqualified and needs to be returned to the factory for re-manufacture; the bottom end of the conveying disc 1 is fixedly connected to a rotating column 26. The bottom end of the rotating column 26 is rotatably provided with a support seat 28. A conveying gear ring 27 is fixedly connected to the surface of the rotating column 26. A conveying motor 25 is installed at the top end of the support seat 28. The output end of the conveying motor 25 is fixedly connected to a conveying gear 24 that meshes with the conveying gear ring 27.

[0042] It should be noted that the conveying motor 25 drives the conveying gear 24 at its output end to rotate intermittently. The conveying gear 24 drives the meshing conveying gear ring 27 to rotate intermittently. The conveying gear ring 27 drives the rotating column 26 at the bottom end of the conveying disc 1 to rotate intermittently, and then drives the conveying disc 1 to rotate intermittently, realizing the intermittent conveying function of the spring.

[0043] Further, a rotating gear ring is fixedly connected to the outer side wall of the rotating groove body 6. A rotating motor 8 is installed at the top end of the compression plate 4. The output end of the rotating motor 8 is fixedly connected to a rotating gear 7 that meshes with the rotating gear ring.

[0044] It should be noted that the rotating motor 8 drives the rotating gear 7 at its output end to rotate, thereby driving the rotating tooth ring meshing with it to rotate. The rotating tooth ring drives the rotating groove body 6 to rotate, and the rotating groove body 6 drives the spring to rotate through the inner support assembly. Under the action of the lower grinding disc 13 and the upper grinding disc 15, the two ends of the spring can be ground flat.

[0045] Further, mounting grooves 2101 are formed on both sides of the inner support block 21. An avoidance type pressure sensor 23 is mounted on the inner wall of the mounting groove 2101, and a protrusion 22 is slidably arranged inside the mounting groove 2101.

[0046] It should be noted that when the vision detection ring 5 moves upward along the spring helix and impacts the protrusion 22, the protrusion 22 will squeeze the avoidance type pressure sensor 23. The avoidance type pressure sensor 23 will feedback to the controller, and the controller controls the electric push rod 19 to work, so that the inner support rod 20 drives the inner support block 21 away from the spring, ensuring that the vision detection ring 5 can continue to move.

[0047] When the present invention is in use, the staff needs to insert the spring onto the spring insertion post 12 on the base 2, use the spring insertion post 12 to temporarily limit the spring, and at the same time make the bottom end of the spring penetrate through the vision detection ring 5. Then, control the lifting motor 9 to drive the lifting lead screw 10 to rotate clockwise. By using the lifting lead screw 10 to cooperate with the threaded through hole in the compression plate 4, the compression plate 4 moves downward. The compression plate 4 drives the inner support rod 20 and the inner support block 21 to move downward to the inside of the spring. Then, the controller controls the electric push rod 19 to work. The electric push rod 19 drives the inner support rod 20 to move, and then drives the inner support block 21 to move, so that the inner support block 21 squeezes the spring from the inside of the spring to realize the support and fixation of the spring;

[0048] After that, use the controller to turn on the rotating motor 8. The rotating motor 8 drives the clockwise rotating gear 7 at its output end to rotate. The rotating gear 7 drives the rotating tooth ring meshing with it to rotate counterclockwise. The rotating tooth ring drives the rotating groove body 6 to rotate. The rotating groove body 6 drives the inner support rod 20 and the inner support block 21 to rotate, and then drives the spring to rotate counterclockwise. Under the rotating action of the spring, the vision detection ring 5 sleeved on the spring moves upward along the spring helix. At the same time, the vision detection ring 5 drives the lifting ring 3 to move upward through the L-shaped rod. During the process of the vision detection ring 5 moving along the spring, the high-temperature resistant camera 18 inside the vision detection ring 5 can take pictures of the spring surface and send the image information to the controller. When the controller identifies that there are defects on the spring surface (such as cracks, burrs, etc. on the spring surface), the controller will control the indicator light 11 to emit light, reminding the staff that the spring is unqualified and needs to be remanufactured. If there are no defects on the spring surface, it means that the surface quality of the spring is qualified;

[0049] When the vision detection ring 5 moves upward and approaches the top of the spring, the vision detection ring 5 will contact the protrusion 22 on the inner support block 21. When the vision detection ring 5 moves upward along the spring helix and impacts the protrusion 22, the protrusion 22 will squeeze the avoidance type pressure sensor 23, and the avoidance type pressure sensor 23 will feedback to the controller. The controller controls the electric push rod 19 to work, so that the inner support rod 20 drives the inner support block 21 away from the spring (after the vision detection ring 5 passes by the inner support block 21, the inner support block 21 will reset and squeeze the inner side of the spring again), ensuring that the vision detection ring 5 can continue to move to the top of the spring and ensuring the comprehensiveness of the vision detection ring 5 for detecting the surface of the spring;

[0050] During the upward movement of the lifting ring 3, the electromagnetic induction heating coil 29 inside it can heat the spring. After the vision detection ring 5 moves to the top of the spring, under the driving action of the rotating motor 8, the rotating groove body 6 rotates clockwise, and then drives the spring to rotate clockwise through the inner support assembly, causing the vision detection ring 5 to spiral downward. When the vision detection ring 5 spirals downward, it will contact the protrusion 22 again, causing the inner support block 21 to avoid the vision detection ring 5, ensuring that the vision detection ring 5 can spiral downward and reset;

[0051] While the vision detection ring 5 spirals downward and resets, the controller controls the lifting motor 9 to work. The lifting motor 9 drives the lifting screw rod 10 to rotate clockwise, causing the compression plate 4 to move downward and compress the spring. When the vision detection ring 5 resets, the lifting motor 9 and the rotating motor 8 stop working. At this time, the compression plate 4 no longer continues to move downward to apply pressure to the spring. The opposed photoelectric sensor 14 will record the downward movement distance of the compression plate 4 and upload it to the controller, and the detection type pressure sensor 17 will detect the spring elastic force at this time;

[0052] During the process of the compression plate 4 compressing the spring, the rotating motor 8 is always in the working state, that is, the spring is always in the rotating state. During this process, the upper grinding disc 15 contacts the top of the spring, and the lower grinding disc 13 contacts the bottom of the spring, realizing the function of grinding the two ends of the spring (the heated spring is easier to be ground, improving the grinding efficiency of the two ends of the spring), thereby reducing the pre-treatment work before spring transportation and indirectly improving the spring transportation efficiency;

[0053] After that, the controller controls the lifting motor 9 again, causing the lifting motor 9 to rotate counterclockwise, so that the compression plate 4 moves upward. When the detection type pressure sensor 17 detects that the spring force is zero, it indicates that the compressed spring has been reset. At this time, the opposed photoelectric sensor 14 will record the upward movement distance of the compression plate 4 and upload it to the controller. The controller compares the downward and upward movement distances of the compression plate 4. If the two are the same, it indicates that the spring can be normally reset after being heated and compressed, indicating that the high temperature resistance performance of the spring is qualified. Otherwise, it indicates that the high temperature resistance performance of the spring is unqualified (the controller will control the indicator light 11 to emit light). Thus, the detection function of the surface quality and high temperature resistance performance of the spring is realized during the conveying process of the spring, which can significantly reduce the subsequent detection items of the spring and further improve the subsequent detection efficiency of the spring.

[0054] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
