Description

Technical Field

[0001] This utility model relates to the technical field of tempering furnace conveying equipment, and in particular to a tempering furnace conveying mechanism that facilitates workpiece positioning. Background Technology

[0002] The tempering furnace is used for tempering general metal parts in air, as well as for quenching, annealing, and aging heat treatment of light alloy parts such as aluminum alloy die castings, pistons, and aluminum plates. The outer shell is welded from steel plates and shaped steel, and the trolley is welded from shaped steel and steel plates. The trolley reduces heat radiation and convection loss through soft contact with the furnace lining and a sand sealing mechanism, effectively ensuring the sealing of the furnace body. A conveying mechanism is required during the use of the tempering furnace.

[0003] A search revealed a Chinese patent (authorization announcement number CN111186677A) disclosing an automated conveying mechanism to prevent workpiece movement deviation. This mechanism includes a conveyor frame, a conveyor roller mounted on the inner wall of the frame, a meshing toothed ring fitted on the outer side of the conveyor roller, the meshing toothed ring engaging with a toothed belt, the toothed belt fixed to the surface of the conveyor belt, a limiting plate on the surface of the conveyor belt, a pad on the surface of the limiting plate, and a reinforcing bar sleeve overlapping the surface of the pad. A mounting frame is also provided on the top surface of the conveyor frame. While this patented technology limits the movement of the reinforcing bar sleeve by adding a limiting plate to prevent collisions between adjacent reinforcing bar sleeves, and by adding a pad and baffle on the limiting plate to prevent the reinforcing bar sleeve from swinging arbitrarily, this patented technology...

[0004] However, the above-mentioned device still has some shortcomings in actual use. The most obvious one is that the current conveying mechanism needs to limit the two sides of the workpiece during the conveying process to prevent the workpiece from deviating during the conveying process, which will affect the workpiece feeding, processing and other processes. However, the current conveying mechanism cannot be adjusted according to the size of the workpiece, and its adaptability is not good. Utility Model Content

[0020] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0021] Reference Figure 1-4 A tempering furnace conveying mechanism for convenient workpiece positioning includes two fixed frames 1. A conveyor belt 2 is arranged between the two fixed frames 1. Two driving blocks 9 are fixedly connected at equal intervals on the outer side of the conveyor belt 2. A fixed frame 14 is arranged on the side of the two fixed frames 1 that is close to each other. A bidirectional lead screw 18 is rotatably connected inside one fixed frame 14, and a positioning rod 15 is fixedly connected inside the other fixed frame 14. The two ends of the bidirectional lead screw 18 are threadedly connected to second limiting plates 16. The second limiting plates 16 are slidably connected to the positioning rod 15. By rotating the conveyor belt 2, multiple workpieces can be conveyed into the tempering furnace. By rotating the bidirectional lead screw 18, the two second limiting plates 16 can be driven to move in opposite directions. The positioning rod 15 makes the second limiting plates 16 more stable during adjustment. The distance between the two second limiting plates 16 can be adjusted according to the width of the workpiece, thereby limiting the workpieces of different sizes and preventing positional deviation during the conveying process.

[0022] Reference Figure 1 A U-shaped frame 5 is fixedly connected between the tops of the two fixed frames 1. The two ends of the inner wall of the U-shaped frame 5 are slidably connected to the first limiting plate 6. Cylinders 7 are fixedly installed on both sides of the U-shaped frame 5. The piston rods of the cylinders 7 extend into the interior of the U-shaped frame 5 and are fixedly connected to the corresponding first limiting plate 6. By extending and retracting the piston rods of the cylinders 7, the first limiting plate 6 inside the U-shaped frame 5 can be moved, thus making it suitable for use with workpieces of different lengths. This facilitates the positioning of the workpiece and further improves the conveying accuracy.

[0023] Reference Figure 4 A monitoring component is provided on the outside of the conveyor belt 2. The monitoring component includes a controller 4 fixedly installed on the outside of one of the fixed frames 1. A support plate 17 is fixedly connected to the top of each fixed frame 1. A position sensor 11 is fixedly installed on the side of each of the two support plates 17 that are close to each other. Through the function of the position sensor 11, the distance between the two sides of the workpiece can be monitored and the information can be transmitted to the controller 4. Then, the controller 4 can control the cylinder 7, thereby adjusting the piston rod stroke of the cylinder 7.

[0024] Reference Figure 3 The fixed frame 1 is equipped with a limiting component inside. The limiting component includes a limiting groove 12 opened on the side of the two fixed frames 1 that are close to each other. The side of the fixed frame 14 close to the fixed frame 1 is fixedly connected to a support block 10. The side of the support block 10 close to the limiting groove 12 is fixedly connected to a limiting post 13. The limiting post 13 is slidably connected to the corresponding limiting groove 12. Through the cooperation of the limiting post 13 and the limiting groove 12, the movement trajectory of the fixed frame 14 can be effectively limited.

[0025] Reference Figure 2 The fixed frame 14 is in contact with the corresponding driving block 9. Two transmission rollers 8 are rotatably installed between the two fixed frames 1. The conveyor belt 2 is connected between the two transmission rollers 8. By moving the driving block 9, the entire fixed frame 14 can be moved.

[0026] Reference Figure 2 A servo motor 3 is fixedly installed on the outside of one of the fixed frames 1. The output shaft of the servo motor 3 passes through the interior of the fixed frame 1 and is fixedly connected to the central shaft of one of the transmission rollers 8. By rotating the output shaft of the servo motor 3, the transmission roller 8 can be driven to rotate, thereby realizing the operation of the conveyor belt 2.

[0027] Working principle: First, multiple workpieces are placed between the corresponding two second limiting plates 16. Then, the bidirectional lead screw 18 can be rotated. The rotation of the bidirectional lead screw 18 can drive the two second limiting plates 16 to move in opposite directions. With the setting of the positioning rod 15, the second limiting plates 16 can be made more stable during the adjustment process. In this way, the distance between the two second limiting plates 16 can be adjusted according to the width of the workpiece, so as to limit the workpieces of different sizes.

[0028] The position sensor 11 can monitor the distance between the two sides of the workpiece and transmit the information to the controller 4. The controller 4 can then control the cylinder 7, thereby adjusting the piston rod stroke of the cylinder 7. This allows the first limiting plate 6 inside the U-shaped frame 5 to move, making it suitable for workpieces of different lengths. This facilitates workpiece positioning and further improves the conveying accuracy.

[0029] As the output shaft of the servo motor 3 rotates, it drives the transmission roller 8 to rotate, which in turn drives the conveyor belt 2 to rotate, thereby transporting multiple workpieces into the tempering furnace.
