Description

Technical Field

[0001] This utility model relates to the field of piston processing technology, and in particular to an automatic transmission production line for piston processing. Background Technology

[0002] With the continuous development of industrial automation and the increasing popularity of various automated equipment, improving production efficiency and quality stability has become one of the important trends and goals of the manufacturing industry. Pistons, as crucial components in mechanical equipment, have a significant impact on the operational stability and lifespan of the equipment. Traditional piston processing methods rely on manual labor, which is not only time-consuming and labor-intensive but also prone to errors and oversights. Furthermore, workpiece accumulation during loading often leads to chaotic loading processes, which are difficult to control and correct for positional deviations, resulting in unstable piston processing quality and affecting the overall operating efficiency and quality of the equipment. Therefore, we propose an automated piston processing production line to address these issues. Utility Model Content

A first bearing is mounted on the top of the second support plate, and the bottom end of the rotating shaft is inserted into the inner cavity of the first bearing. A turntable is fixedly connected to the top of the rotating shaft, and two centrally symmetrical pressure sensors are mounted on the top of the turntable. Each pressure sensor has a fixed base on its top, and a storage slot is formed on the top of the fixed base. A clamping mechanism is provided in the inner cavity of each of the two storage slots.

[0005] Furthermore, both first baffles are located at the top of the conveyor belt, and the two first baffles are arranged symmetrically about the central axis of the conveyor belt.

[0006] Furthermore, the transfer and conveying mechanism includes two connecting plates, which are respectively fixedly connected to the front and rear sides of the first support plate. A fixed cylinder is fixedly connected between the two connecting plates, and a matching rolling column is rotatably connected to the inner cavity of the fixed cylinder. Several fixing grooves are evenly opened on the outer wall of the rolling column, and a drive shaft is fixedly connected through the center of the front and rear ends of the rolling column. Through holes matching the drive shaft are opened at the center of the front and rear sides of the fixed cylinder. A second bearing is provided on both connecting plates. The rear end of the drive shaft passes through the through hole and is inserted into the inner cavity of the rear second bearing. A drive motor is provided on the front side of the connecting plate located on the front side. The front end of the drive shaft passes through the adjacent through hole and the inner cavity of the front second bearing and is fixedly connected to the power output end of the drive motor. A feed port is opened on the upper left side of the fixed cylinder, and a discharge port is opened directly below the fixed cylinder.

[0007] Furthermore, a sloping plate is fixedly connected to the left side of the fixed cylinder, and the right side of the sloping plate is located at the bottom of the feed inlet. A second baffle is slidably connected to both the front and rear sides of the top of the sloping plate, and the second baffle is fixedly connected to the adjacent first baffle.

[0008] Furthermore, the clamping mechanism includes a first electric telescopic rod, which is disposed on the top center side of the fixed base near the turntable. A horizontal clamping plate is fixedly connected to the power end of the first electric telescopic rod. A groove is provided at the bottom of the inner cavity of the storage slot, and a second electric telescopic rod is disposed at the bottom of the inner cavity of the groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. By setting up an electro-hydraulic actuator, a first baffle, an inclined plate, and a second baffle, when the workpiece is pushed by the conveyor belt, the electro-hydraulic actuator is activated to push the first baffle to move longitudinally and adjust the horizontal distance between the two first baffles and the second baffle. This allows for the conveying of piston workpieces of different sizes. The workpiece is then guided from the feed port into the fixed groove on the rolling column. The drive motor drives the drive shaft to rotate, which in turn drives the rolling column to rotate. The rotating column causes the workpiece to rotate clockwise and be placed into the storage groove on the fixed seat below through the discharge port. The arrangement of several fixed grooves ensures that the workpieces are conveyed in an orderly manner and avoids the accumulation of workpieces on the production line, which would lead to chaotic feeding.

[0013] 2. Through the arrangement of the first electric telescopic rod, horizontal clamping plate, second electric telescopic rod, lifting plate, and vertical clamping plate, when the workpiece falls into the inner cavity of the storage slot, it will roll downwards and contact the vertical clamping plate. Subsequently, by activating the first electric telescopic rod, the horizontal clamping plate is pushed closer to the piston workpiece, thereby clamping and fixing the piston workpiece in the storage slot. Through the linkage of the drive motor, transmission bevel gear, driven bevel gear, and rotating shaft, the turntable is driven to rotate, which can turn the piston workpiece at multiple angles, ensuring that the processing angle of the piston meets the requirements of automated feeding and processing, and improving the stability of the piston workpiece during processing, thus improving the processing quality.

[0014] 3. By activating the second electric telescopic rod to pull the lifting plate vertically downward, the vertical clamping plate can be retracted into the inner cavity of the groove. With the bottom of the inner cavity of the storage slot tilted, the processed piston workpiece can be quickly slid from the storage slot onto the external conveyor belt and moved to the subsequent processing position, realizing automated unloading and improving production efficiency.

[0023] Please see Figures 1 to 7 The present invention provides the following technical solution:

[0024] An automated conveyor production line for piston processing includes a first support plate 1 and a second support plate 7 disposed on the right side of the first support plate 1. First support legs 2 are fixedly connected to the four bottom corners of the first support plate 1, and second support legs 8 are fixedly connected to the four bottom corners of the second support plate 7. A conveyor belt 4 is provided on the top of the first support plate 1, and fixed plates 3 are provided on both the front and rear sides of the conveyor belt 4. The bottoms of the two fixed plates 3 are fixedly connected to the first support plate 1. Two electro-hydraulic actuators 5 are provided on each of the two fixed plates 3, distributed laterally. The power ends of two laterally adjacent electro-hydraulic actuators 5 are fixedly connected to the same first stop. Plate 6 and two first baffles 6 are located on top of conveyor belt 4, and the two first baffles 6 are symmetrically arranged about the central axis of conveyor belt 4. By activating the electro-hydraulic actuator 5, the first baffles 6 are moved horizontally and longitudinally, thereby adjusting the horizontal distance between the two first baffles 6. This allows for the limiting of piston workpieces of different sizes, preventing them from falling off conveyor belt 4 during transport. A transfer conveying mechanism is provided on the right side of the first support plate 1, and a drive motor 9 is provided on the top of the second support plate 7. The power output end of the drive motor 9 is fixedly connected to a transmission bevel gear 10. A driven bevel gear 11 is engaged on the left side, and a rotating shaft 12 is fixedly fixed through the center of the driven bevel gear 11. A first bearing is provided on the top of the second support plate 7, and the bottom end of the rotating shaft 12 is inserted into the inner cavity of the first bearing. A turntable 13 is fixedly connected to the top of the rotating shaft 12. Limiting support columns 33 are fixedly connected to the left and right sides of the bottom of the turntable 13. An annular limiting groove 34 adapted to the two limiting support columns 33 is opened on the top of the second support plate 7, and the bottom ends of the two limiting support columns 33 are inserted into the inner cavity of the annular limiting groove 34, which improves the stability of the turntable 13 when rotating. The top of the turntable 13 is provided with There are two centrally symmetrical pressure sensors 14. Each pressure sensor 14 has a fixed base 15 on its top, and the top of the fixed base 15 has a storage groove 16. When the piston workpiece falls into the inner cavity of the storage groove 16, the pressure sensor 14 receives the weight signal and starts the drive motor 9. The drive motor 9 drives the transmission bevel gear 10 to rotate, the transmission bevel gear 10 drives the driven bevel gear 11 to rotate, the driven bevel gear 11 drives the rotating shaft 12 to rotate, and the rotating shaft 12 drives the turntable 13 to rotate, so that the piston can be rotated at multiple angles. The inner cavity of each storage groove 16 is equipped with a clamping mechanism.

[0025] The transfer mechanism includes two connecting plates 24, which are fixedly connected to the front and rear sides of the first support plate 1, respectively. A fixed cylinder 23 is fixedly connected between the two connecting plates 24, and a matching rolling column 26 is rotatably connected to the inner cavity of the fixed cylinder 23. Several fixing grooves 27 are evenly opened on the outer wall of the rolling column 26, and a drive shaft 30 is fixedly inserted through the center of both the front and rear ends of the rolling column 26. Through holes matching the drive shaft 30 are opened at the center of both the front and rear sides of the fixed cylinder 23. A second bearing is provided on each of the two connecting plates 24. The rear end of the drive shaft 30 passes through the through hole and is inserted into the inner cavity of the rear second bearing. A drive motor 25 is provided on the front side of the front connecting plate 24. The front end of the drive shaft 30 passes through the adjacent through hole and the inner cavity of the front second bearing, and is fixedly connected to the power output end of the drive motor 25. Next, a feed inlet 28 is provided on the upper left side of the fixed cylinder 23. An inclined plate 31 is fixedly connected to the left side of the fixed cylinder 23, and the right side of the inclined plate 31 is located at the bottom of the feed inlet 28. A second baffle 32 is slidably connected to the front and rear sides of the top of the inclined plate 31, and the second baffle 32 is fixedly connected to the adjacent first baffle 6. The longitudinal horizontal movement of the first baffle 6 can drive the second baffle 32 to move synchronously, so that piston workpieces of different sizes can be accurately introduced into the inner cavity of the fixed cylinder 23. A discharge port 29 is provided directly below the fixed cylinder 23. When the piston workpiece is pushed to the right on the conveyor belt 4, it can slide down through the inclined plate 31 into the fixed groove 27 on the rolling column 26. Then, the transmission motor 25 drives the transmission shaft 30 to rotate, and the rotation of the transmission shaft 30 drives the rolling column 26 to rotate clockwise, so that the piston workpiece can be pushed to the discharge port 29.

[0026] The clamping mechanism includes a first electric telescopic rod 21, which is located on the top center side of the fixed base 15 near the turntable 13. A horizontal clamping plate 22 is fixedly connected to the power end of the first electric telescopic rod 21. A groove 17 is provided at the bottom of the inner cavity of the storage slot 16, and a second electric telescopic rod 18 is provided at the bottom of the inner cavity of the groove 17. A lifting plate 19 is fixedly connected to the power end of the second electric telescopic rod 18, and a vertical clamping plate 20 is fixedly connected to the top of the lifting plate 19. When the piston workpiece falls from the discharge port 29 into the storage slot 16... After the inner cavity of 6 is opened, the first electric telescopic rod 21 is activated to push the horizontal clamping plate 22 to clamp and fix the piston workpiece, thereby improving the stability during processing. The side of the storage groove 16 away from the top center of the turntable 13 is open, and the bottom of the inner cavity of the storage groove 16 is sloped. When it is necessary to unload the processed workpiece, the second electric telescopic rod 18 is activated to pull the lifting plate 19 vertically downward. The lifting plate 19 drives the vertical clamping plate 20 to move downward and retract into the inner cavity of the groove 17, so that the piston workpiece can slide out from the storage groove 16.

[0027] Working Principle: In use, this invention firstly, based on the size of the workpiece, the electro-hydraulic actuator 5 is activated to push the first baffle 6 horizontally, thereby adjusting the horizontal distance between the two first baffles 6. This ensures that the piston workpiece is conveyed orderly on the conveyor belt 4 while preventing it from falling off. The horizontal movement of the first baffle 6 drives the second baffle 32 to move synchronously, thus adjusting the horizontal distance between the two second baffles 32. This allows the workpiece to slide precisely from the feed port 28 into the fixed cylinder 23 and into the fixed groove 27. The drive motor 25 drives the drive shaft 30 to rotate, which in turn drives the rolling column 26 to rotate clockwise. This transfers the piston workpiece and allows it to fall from the discharge port 29 into the lower storage groove 16. Because the bottom of the inner cavity of the storage groove 16 is sloped, the piston workpiece... The vertical clamping plate 20 is attached to the vertical clamping plate 20, so that when the first electric telescopic rod 21 is activated to push the horizontal clamping plate 22 close to the piston workpiece, the piston workpiece can be clamped and fixed in the inner cavity of the storage groove 16. When the pressure sensor 14 receives the information of weight change, the drive motor 9 is activated to drive the transmission bevel gear 10 to rotate. The rotation of the transmission bevel gear 10 drives the driven bevel gear 11 to rotate. The rotation of the driven bevel gear 11 drives the rotating shaft 12 to rotate. The rotation of the rotating shaft 12 drives the turntable 13 to rotate. The rotation of the turntable 13 drives the fixed seat 15 to rotate, so that the piston workpiece can be turned at multiple angles. When the piston workpiece is processed, the second electric telescopic rod 18 is activated to pull the lifting plate 19 to move vertically downward and retract the vertical clamping plate 20 into the inner cavity of the groove 17, so that the piston workpiece can slide down in the storage groove 16 onto the external conveyor belt and continue subsequent processing operations.
