Description

Technical Field

[0001] The present invention relates to the technical field of quenching, and particularly to a material selection and sorting device for a workpiece induction quenching machine tool. Background Art

[0002] Workpiece induction quenching is a common and important heat treatment process, which can effectively improve the surface hardness, wear resistance and fatigue strength of workpieces, and is widely used in many industries such as automobile manufacturing, aerospace, and mechanical equipment.

[0003] Traditional workpiece quenching operations often rely on manual operation for material selection. During the production process of workpieces, there will be dimensional errors. For example, in turning processing, if the feed rate calculation is incorrect or the tool wears and loosens and is not replaced and adjusted in time, the outer diameter and other dimensions of the workpiece will be too large. Workers need to select workpieces with appropriate dimensions from a large number of workpieces and place them at the feeding position of the quenching machine tool so that the subsequent quenching processing can proceed smoothly.

[0004] This manual operation method has many drawbacks: the efficiency of manual material selection is low, it is difficult to meet the needs of large-scale production, and it seriously restricts the improvement of production efficiency. The accuracy and consistency of manual operation are poor. It is easy to cause material selection errors due to factors such as worker fatigue and negligence, which affect the quenching quality and increase the scrap rate. Moreover, the manual labor intensity is large. Long-term repetitive work is not conducive to the physical health of workers and also increases the labor cost of the enterprise. Summary of the Invention

[0005] To achieve the above object, the present invention is realized through the following technical solutions: A material selection and sorting device for a workpiece induction quenching machine tool, comprising: A base, and a frame fixedly installed on the top of the base, wherein a limiting component and a reset component are installed on the opposite sides of the inner wall of the frame; A quenching machine tool, which is arranged on one side of the frame. A material guiding plate is fixedly connected between the frame and the quenching machine tool. A material guiding groove is formed on the surface of the material guiding plate. The material guiding plate is inclined, and the lower end of the material guiding plate is connected to the quenching machine tool. The material guiding plate is used to receive the workpieces after material selection and sorting and guide them into the quenching machine tool for subsequent processing; A conveying mechanism, which includes a second motor and rotating rollers. The number of rotating rollers is two. The two rotating rollers are rotatably installed at both ends of the frame. The shaft ends of the rotating rollers penetrate through the frame and extend to both sides thereof. The output end of the second motor is fixedly connected to the shaft end of the rotating roller, and the second motor is fixedly installed on the side surface of the frame through a bracket. A conveyor belt is drivingly installed on the outer surface of the rotating roller. The conveyor belt is arranged on one side of the rotating roller. The conveying mechanism carries and conveys the workpieces so that they can move on the device according to the process; The material selection component is installed on one side of the conveyor belt; The placement component is installed on the surface of the material selection component. The placement component cooperates with the material selection component to screen out qualified workpieces for processing; Among them, the material selection component includes a first rotating shaft and a rotating plate. The rotating plate is rotatably installed on the side of the conveyor belt through the first rotating shaft. An arc-shaped buffer air cushion is fixedly installed on the surface of the rotating plate. The placement component and the arc-shaped buffer air cushion are oppositely arranged on both sides of the rotating plate. The arc-shaped buffer air cushion can absorb the extrusion impact force received when the rotating plate resets. A limiting spring is fixedly connected between the rotating plate and the conveyor belt. The limiting spring can limit the rotation range of the rotating plate and reset it to a certain extent.

[0006] Preferably, a first fixing frame is fixedly installed at the end of the rotating plate, and a second rotating shaft is rotatably installed inside the first fixing frame.

[0007] Preferably, the quenching machine tool includes a frame body, a first motor, and a quenching part. The first motor is fixedly installed on the top of the frame body through a bracket. The output end of the first motor is connected to a transmission lifting part. The transmission lifting part is arranged inside the frame body and is used to fix the workpiece and make it rotate. The quenching part is fixedly installed inside the frame body and is arranged directly below the transmission lifting part. A control panel is fixedly installed on the outer surface of the frame body. The quenching of the workpiece is controlled by the controller in the control panel.

[0008] Preferably, the placement component includes a placement plate and clamping plates. The bottom of the placement plate is fixedly installed on the outer surface of the second rotating shaft. The clamping plates are rotatably installed on both sides of the placement plate through rotating shafts. A clamping spring is fixedly connected between the outer surface of the clamping plates and the top of the rotating plate. The clamping plates cooperate with the clamping spring to play a role in clamping and positioning workpieces with too large outer diameters to a certain extent. The clamping plates use the elastic force of the clamping spring to clamp the workpieces. During the material selection and transportation processes, workpieces with too large outer diameters are stably clamped to prevent them from shifting, falling, or getting chaotic during the operation of the device, ensuring the orderliness of the workpieces in the screening and transportation links, ensuring the stable operation of the entire device, and reducing processing errors or equipment failures caused by changes in the positions of the workpieces.

[0009] Preferably, rollers are rotatably installed on the surface of the placement plate through rotating shafts. The rollers can reduce the friction force when the workpiece slides on the placement plate, reduce surface scratches, wear, and other damages caused by friction during the sliding process of the workpiece, and protect the surface quality of the workpiece. A screening plate is fixedly installed at one end of the placement plate.

[0010] Preferably, through holes are formed on the surface of the sieve plate, and the diameter of the through holes is slightly larger than the diameter of normal workpieces. The sieve plate can screen the workpieces. Since the diameter of the through holes on the sieve plate is slightly larger than the diameter of normal workpieces, the workpieces that meet the size requirements pass through the sieve plate and then enter the quenching machine tool through the material guiding plate, while the workpieces with too large outer diameters will remain on the placing plate.

[0011] Preferably, guide plates are fixedly installed on both sides at the edge of the through holes of the sieve plate. The guide plates are used to guide the workpieces to the positions of the through holes of the sieve plate and play a blocking role for the workpieces with too large outer diameters, avoiding unqualified workpieces from entering the quenching machine tool and affecting the processing quality. The other ends of the guide plates are fixedly connected to the inner bent surfaces of the clamping plates, and friction blocks are fixedly installed on the inner bent surfaces of the guide plates. The friction blocks can further assist in positioning and other operations for the workpieces with too large outer diameters.

[0012] Preferably, the limiting assembly includes a first fixing plate, the first fixing plate is fixedly installed on the surface of the machine frame, a limiting plate is fixedly installed on the surface of the first fixing plate, a receiving hole is formed on the surface of the limiting plate, and a rubber cushion block is fixedly installed at the bottom of the limiting plate. The rubber cushion block is in extrusion fit with the clamping plate. When the workpiece is placed on the placing plate, due to the action of gravity, the rotating plate and the placing plate will tilt, and the rubber cushion block is in extrusion with the clamping plate, which will play a certain role in limiting and regularizing the workpiece, ensuring that the rotating plate and the placing plate no longer tilt, ensuring that the workpiece can enter the material guiding plate at the correct position and finally enter the quenching machine tool, improving the accuracy and consistency of the quenching process, and being beneficial to improving the product quality and production efficiency.

[0013] Preferably, the reset assembly includes an inclined block and a roller. The inclined block is fixedly installed inside the machine frame, and the inclined block is arranged between the placing assemblies. The inclined setting of the inclined block is beneficial to the realization of subsequent related reset actions.

[0014] Preferably, a second fixing frame is fixedly installed on the surface of the inclined block, the roller is rotatably installed inside the second fixing frame through a rotating shaft, a rubber strip is fixedly installed on the outer surface of the roller, and the rubber strip is in extrusion fit with the arc-shaped buffer air cushion. The roller assists in the reset of components such as the rotating plate, ensuring the continuous and stable operation of the device.

[0015] The present invention provides a material selection and sorting device for a workpiece induction quenching machine tool. It has the following beneficial effects: 1. The material selection and sorting device of the workpiece induction hardening machine tool, through the setting of the sieve plate in the placement component, the through-hole diameter of the sieve plate is slightly larger than the diameter of the normal workpiece. When the workpiece is conveyed onto the placement plate, with the operation of the device, the workpiece moves towards one end of the sieve plate. The workpieces that meet the size pass through the through-holes and enter the hardening machine tool through the material guiding plate, while the workpieces with too large outer diameters are left on the placement plate. The sieve plate can effectively screen out the workpieces with qualified sizes, avoid unqualified workpieces from entering the hardening machine tool and affecting the processing quality, improve the precision and qualification rate of the processed products, and at the same time reduce the waste of resources and equipment loss caused by the processing of unqualified workpieces.

[0016] 2. The material selection and sorting device of the workpiece induction hardening machine tool, through the setting of the clamping plates in the placement component, the clamping plates are rotatably installed on both sides of the placement plate through rotating shafts, and a clamping spring is connected between the outer surface of the clamping plate and the top of the rotating plate. When the workpiece with too large outer diameter is placed on the placement plate, the workpiece presses the clamping plate, causing the clamping spring to deform. The clamping plate uses the elastic force of the clamping spring to clamp the workpiece, and stably clamps the workpiece with too large outer diameter during the material selection and conveying process, preventing it from shifting, falling or getting disordered during the operation of the device, ensuring the orderliness of the workpiece in the screening and conveying links, ensuring the stable operation of the entire device, and reducing the processing errors or equipment failures caused by the position change of the workpiece.

[0017] 3. The material selection and sorting device of the workpiece induction hardening machine tool, through the installation of an arc-shaped buffer air cushion on the surface of the rotating plate in the material selection component, during the reset process of the rotating plate, the rubber strip on the outer surface of the roller in the reset component presses against the arc-shaped buffer air cushion, assisting the rotating plate to reset and buffer. The arc-shaped buffer air cushion effectively reduces the damage to the workpiece when various components collide, protects the surface quality of the workpiece, at the same time reduces the impact force on the rotating plate, reduces the risk of its wear and damage, extends the service life of the rotating plate, and the cooperation and buffering of the rubber strip and the arc-shaped buffer air cushion make the reset process of the rotating plate stable, reduce the impact on the overall structure of the device, and improve the stability and reliability of the device.

[0018] 4. The material selection and sorting device of the workpiece induction hardening machine tool, through the setting of the limiting component, when the workpiece is placed on the placement plate, due to the gravity, the rotating plate and the placement plate will tilt. At this time, the rubber cushion block presses against the clamping plate, which will keep the placement plate and the rotating plate in a horizontal state. Through the extrusion of the rubber cushion block and the clamping plate, the workpiece is limited in the horizontal direction, regularizing the posture of the workpiece, ensuring that the workpiece can enter the material guiding plate at the correct position and finally enter the hardening machine tool, improving the accuracy and consistency of the hardening process, and being beneficial to improving the product quality and production efficiency.

[0019] V. The material selection and sorting device of the workpiece induction hardening machine tool, through the setting of the reset component, when the material selection component moves to the reset component and the arc-shaped buffer air cushion on the rotating plate contacts the rubber strip outside the roller, due to the inclined setting of the inclined block, the roller can rotate through the rotating shaft, and the rubber strip and the arc-shaped buffer air cushion interact with each other to push the rotating plate to rotate upward. With the assistance of the limit spring, the rotating plate returns to its initial position, and the reset component realizes the automatic reset of the rotating plate without manual intervention, ensuring that the device can operate continuously and stably, reducing the equipment downtime caused by the abnormal position of the rotating plate, improving production efficiency, reducing the manual maintenance cost, and making the entire material selection and sorting device have better automation performance and reliability.

Detailed Embodiments

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] The first embodiment, as Figures 1 to 4 As shown, the present invention provides a technical solution: a material selection and sorting device for a workpiece induction hardening machine tool, comprising: A base 1, and a frame 10 fixedly mounted on the top of the base 1, wherein a limit assembly 7 and a reset assembly 8 are mounted on opposite sides of the inner wall of the frame 10; A quenching machine 2 is provided on one side of a frame 10. A guide plate 3 is fixedly connected between the frame 10 and the quenching machine 2. A guide groove 9 is provided on the surface of the guide plate 3. The guide plate 3 is tilted, and a lower end of the guide plate 3 is connected to the quenching machine 2. The guide plate 3 is used to receive the workpieces after material selection and sorting and introduce them into the quenching machine 2 for subsequent processing. The quenching machine 2 includes a frame 21, a first motor 22 and a quenching member 24. The first motor 22 is fixedly installed on the top of the frame 21 through a bracket. The output end of the first motor 22 is connected to a transmission lifting member 23. The transmission lifting member 23 is arranged inside the frame 21. The transmission lifting member 23 is used to fix the workpiece and rotate it. The quenching member 24 is fixedly installed inside the frame 21, and the quenching member 24 is arranged directly below the transmission lifting member 23. A control panel 25 is fixedly installed on the outer surface of the frame 21. The quenching member 24 is controlled by a controller in the control panel 25 to induce the quenching of the workpiece.

[0024] The conveying mechanism 4 includes a second motor 41 and a rotating roller 42. There are two rotating rollers 42. The two rotating rollers 42 are rotatably mounted at both ends of the frame 10. The shaft ends of the rotating rollers 42 penetrate the frame 10 and extend to both sides thereof. The output end of the second motor 41 is fixedly connected to the shaft ends of the rotating rollers 42, and the second motor 41 is fixedly mounted on the side of the frame 10 through a bracket. A conveyor belt 43 is installed on the outer surface of the rotating roller 42 for transmission. The conveyor belt 43 is arranged on one side of the rotating roller 42. The conveying mechanism 4 carries and transports the workpiece so that it can move on the device according to the process. When the second motor 41 is running, it drives the rotating rollers 42 to rotate, thereby starting the conveyor belt 43 to run, and the workpiece to be processed starts to be transported as the conveyor belt 43 runs.

[0025] The second embodiment is based on the first embodiment. Figures 1 to 7 As shown, the material selection assembly 5 is installed on one side of the conveyor belt 43; The material selection component 5 includes a first rotating shaft 51 and a rotating plate 52. The rotating plate 52 is rotatably installed on the side of the conveyor belt 43 through the first rotating shaft 51. An arc-shaped buffer air cushion 53 is fixedly installed on the surface of the rotating plate 52. The placing component 6 and the arc-shaped buffer air cushion 53 are oppositely arranged on both sides of the rotating plate 52. The arc-shaped buffer air cushion 53 can absorb the extrusion impact force received when the rotating plate 52 resets. A limiting spring 54 is fixedly connected between the rotating plate 52 and the conveyor belt 43. The limiting spring 54 can limit the rotation range of the rotating plate 52 and reset it to a certain extent; A first fixing frame 55 is fixedly installed at the end of the rotating plate 52. A second rotating shaft 56 is rotatably installed inside the first fixing frame 55; The placing component 6 is installed on the surface of the material selection component 5. The placing component 6 cooperates with the material selection component 5 to screen out qualified workpieces for processing; The placing component 6 includes a placing plate 61 and clamping plates 62. The bottom of the placing plate 61 is fixedly installed on the outer surface of the second rotating shaft 56. The clamping plates 62 are rotatably installed on both sides of the placing plate 61 through rotating shafts. A clamping spring 67 is fixedly connected between the outer surfaces of the clamping plates 62 and the top of the rotating plate 52. The clamping plates 62 and the clamping spring 67 cooperate to play a role in clamping and positioning workpieces with too large an outer diameter to a certain extent; Rollers 63 are rotatably installed on the surface of the placing plate 61 through rotating shafts. The rollers 63 can reduce the friction force when the workpiece slides on the placing plate 61. One end of the placing plate 61 is fixedly installed with a sieve plate 64; Through holes are formed on the surface of the sieve plate 64. The diameter of the through holes is slightly larger than the diameter of normal workpieces. The sieve plate 64 can screen the workpieces. Since the diameter of the through holes on the sieve plate 64 is slightly larger than the diameter of normal workpieces, the workpieces that meet the size requirements pass through the sieve plate 64 and then enter the quenching machine tool 2 through the guide plate 3. The workpieces with too large an outer diameter will remain on the placing plate 61; On both sides at the edge of the through holes of the sieve plate 64, guide plates 65 are fixedly installed. The guide plates 65 are used to guide the workpieces to the positions of the through holes of the sieve plate 64 and block the workpieces with too large outer diameters. The other ends of the guide plates 65 are fixedly connected to the inner bent surfaces of the clamping plates 62. Friction blocks 66 are fixedly installed on the inner bent surfaces of the guide plates 65. The friction blocks 66 can further assist in positioning the workpieces with too large outer diameters. When the workpieces are placed on the placement plate 61, due to the action of gravity, the rotating plate 52 and the placement plate 61 will tilt. If the workpiece size is normal, the workpiece will directly fall through the through holes of the sieve plate 64 at one end of the placement plate 61 and slide along the material guide groove 9 of the material guide plate 3 to the quenching machine tool 2. For workpieces with too large outer diameters that cannot pass through the through holes of the sieve plate 64, they continue to move with the device on the placement plate 61. At this time, the workpiece presses the clamping plate 62, causing the clamping plate 62 to rotate around the rotating shaft, and the clamping spring 67 is compressed. The clamping plate 62 generates a clamping force on the workpiece. At the same time, the guide plate 65 blocks and guides the workpieces with too large outer diameters, and the friction blocks 66 on the guide plate 65 further assist in positioning to prevent the workpieces from moving randomly on the placement plate 61.

[0026] The third embodiment is based on the first and second embodiments. Please refer to Figures 1 to 9 As shown, the limiting component 7 includes a first fixing plate 71. The first fixing plate 71 is fixedly installed on the surface of the frame 10. A limiting plate 72 is fixedly installed on the surface of the first fixing plate 71. A receiving hole 74 is formed on the surface of the limiting plate 72; A rubber cushion block 73 is fixedly installed at the bottom of the limiting plate 72. The rubber cushion block 73 is squeezed and adapted to the clamping plate 62. When the workpiece is placed on the placement plate 61, due to the action of gravity, the rotating plate 52 and the placement plate 61 will tilt. And the rubber cushion block 73 is squeezed with the clamping plate 62, which will play a certain role in limiting and regularizing the workpiece to ensure that the rotating plate 52 and the placement plate 61 no longer tilt; The reset component 8 includes an inclined block 81 and a roller 83. The inclined block 81 is fixedly installed inside the frame 10. The inclined block 81 is arranged between the placement components 6. The inclined setting of the inclined block 81 is beneficial to the realization of subsequent related reset actions; The surface of the inclined block 81 is fixedly installed with a second fixing frame 82. The roller 83 is rotatably installed inside the second fixing frame 82 through a rotating shaft. A rubber strip 84 is fixedly installed on the outer surface of the roller 83. The rubber strip 84 is squeezed and adapted to the arc-shaped buffer air cushion 53. The roller 83 assists in the reset of components such as the rotating plate 52 to ensure the continuous and stable operation of the device. When the material selection component 5 moves to the position of the reset component 8 along with the operation of the conveyor belt 43, the arc-shaped buffer air cushion 53 on the rotating plate 52 will come into contact with the rubber strip 84 outside the roller 83. Due to the set inclination angle of the inclined block 81 and the fact that the roller 83 can rotate through the rotating shaft, under this structural design, an interaction occurs between the rubber strip 84 and the arc-shaped buffer air cushion 53. The rubber strip 84 will exert a pushing force on the arc-shaped buffer air cushion 53, prompting the rotating plate 52 to start rotating upward. During the rotation process, the limiting spring 54 plays an auxiliary role and cooperates with the pushing action of the rubber strip 84, enabling the rotating plate 52 to gradually return to its initial horizontal position.

[0027] During use, the staff turns on the second motor 41 and places the workpiece on the placement plate 61. Due to the effect of the feeding end limiting component 7, the placement plate 61 and the rotating plate 52 remain in a horizontal state. The second motor 41 drives the rotating roller 42 to rotate, thereby causing the conveyor belt 43 to start running. The workpiece to be processed starts to be conveyed along with the operation of the conveyor belt 43. When the workpiece runs out of the limiting component 7, due to the effect of gravity, the rotating plate 52 and the placement plate 61 will tilt. When tilting to a certain extent, the limiting spring 54 limits it to prevent excessive tilting. At the same time, the guide plate 3 also plays a limiting role on the rotating plate 52; At this time, the workpiece slides on the inclined placement plate 61, and the rollers 63 can reduce the friction force when the workpiece slides on the placement plate 61. If the workpiece size is normal, the workpiece will directly fall through the through holes on the sieve plate 64 at one end of the placement plate 61 and slide towards the quenching machine tool 2 through the material guiding groove 9 of the guide plate 3. For workpieces with a larger outer diameter that cannot pass through the through holes of the sieve plate 64, they continue to move with the device on the placement plate 61. At this time, the workpiece squeezes the clamping plate 62, causing the clamping plate 62 to rotate around the rotating shaft, and the clamping spring 67 is compressed. The clamping plate 62 generates a clamping force on the workpiece. At the same time, the guide plate 65 plays a role in blocking and guiding the workpiece with an over-large outer diameter, and the friction blocks 66 on the guide plate 65 further assist in positioning to prevent the workpiece from moving randomly on the placement plate 61; When the material selection component 5 moves to the reset component 8, when the arc-shaped buffer air cushion 53 on the rotating plate 52 comes into contact with the rubber strip 84 outside the roller 83, due to the inclined setting of the inclined block 81 and the rotatability of the roller 83 through the rotating shaft, the rubber strip 84 and the arc-shaped buffer air cushion 53 interact with each other, pushing the rotating plate 52 to rotate upward. With the assistance of the limiting spring 54, the rotating plate 52 returns to its initial position to ensure the continuous and stable operation of the device.
