After marking is completed, the air shaft releases the flywheel, and the positioning seat and positioning column descend sequentially. The roller conveyor assembly continues to transport the flywheel forward, thus completing the loading and unloading of the flywheel for marking. During this process, no worker is required to position the flywheel, which improves marking efficiency.

Description

Technical Field

[0001] This utility model relates to the field of flywheel production equipment technology, and in particular to a flywheel marking and unloading device. Background Technology

[0002] A flywheel, a disc-shaped component with a large moment of inertia, functions like an energy storage device. In a four-stroke engine, power is done only once every four piston strokes; the exhaust, intake, and compression strokes all consume power. Therefore, the torque output by the crankshaft varies periodically, and the crankshaft speed is unstable. To improve this situation, a flywheel is installed at the rear end of the crankshaft.

[0003] Existing flywheel marking technology mostly uses pneumatic marking methods. This method of flywheel marking is time-consuming and noisy, which is not conducive to workers operating the equipment for long periods of time. To address this, Chinese Utility Model Patent CN 216177641 U discloses a flywheel laser marking machine, which includes a frame, a control cabinet located below the frame, and an automatic feeding roller conveyor installed above the control cabinet on the frame. The power output end of the automatic feeding roller conveyor is equipped with a roller motor, etc. The aforementioned flywheel laser marking machine improves upon traditional laser marking machines by adding automatic feeding roller conveyors, feeding roller conveyor lines, and positioning fixtures. This allows the flywheel to be processed at the laser marking machine itself. The flywheel is manually placed into the positioning fixture within the laser marking machine, and the marking components are controlled via the control cabinet and control panel on the machine frame. At this point, the automatic feeding roller conveyor, feeding roller conveyor line, roller motor, and laser engraving head are activated. After the workpiece is inspected, the flywheel at the positioning fixture is automatically marked by the laser engraving head. After marking is completed, the cylinder pushes the positioning fixture downwards, causing the flywheel to fall onto the automatic feeding roller conveyor and be sent outwards to the feeding roller conveyor line for external transport.

[0004] However, when the aforementioned flywheel laser marking machine is in operation, the flywheel needs to be manually placed into the positioning fixture for fixation, which makes the loading and unloading of the flywheel inconvenient and affects the marking efficiency. Utility Model Content

[0005] In order to overcome the above-mentioned defects in the existing technology, this utility model provides a flywheel marking and unloading device.

[0006] The technical solution adopted by the present utility model to solve its technical problems is as follows: An upper and lower material discharging device for flywheel marking, which includes a laser marking machine body. A feeding mechanism is horizontally penetrated and arranged on the side of the laser marking machine body. The feeding mechanism includes a fixing frame, and a roller conveying component is installed on the top of the fixing frame. An installation frame is arranged inside the laser marking machine body, and the installation frame is fixedly installed at the bottom of the fixing frame. A positioning seat is installed on the installation frame in a liftable manner, and an air shaft is installed in cooperation with the positioning seat. A material blocking component is arranged on one side of the positioning seat close to the discharging end of the roller conveying component.

[0007] Furthermore, the roller conveying component includes a conveying support frame, and the conveying support frame is fixedly installed on the top of the fixing frame. A plurality of groups of conveying rollers are rotatably installed inside the conveying support frame, and the conveying rollers are uniformly arranged in an array on the conveying support frame. There is an interval section in the middle of the conveying rollers above the installation frame, and both the positioning seat and the material blocking component are arranged inside the interval section.

[0008] Furthermore, adjacent conveying rollers are respectively connected by a sprocket chain component. A motor fixing frame is fixedly installed at the bottom of the conveying support frame, and a driving motor is fixedly installed on the motor fixing frame. The power output shaft of the driving motor is connected to any one group of the conveying rollers through the sprocket chain component.

[0009] Furthermore, a connecting platform is arranged at the bottom end of the positioning seat, and a plurality of groups of first guide rods are slidably installed on the connecting platform. The first guide rods are fixedly installed on the installation frame, and a first cylinder is fixedly installed at the bottom of the installation frame. The power output end of the first cylinder is fixedly connected to the bottom of the positioning seat.

[0010] Furthermore, the material blocking component includes a moving frame, and the moving frame is in a "U" - shaped structure. Two groups of second guide rods are slidably installed on the top plate of the moving frame, and the top ends of the second guide rods are fixedly installed with a mounting plate. Positioning columns are fixedly installed at both ends of the mounting plate. A second cylinder is fixedly installed at the top and bottom of the moving frame, and the power output shaft of the cylinder is fixedly connected to the mounting plate.

[0011] Furthermore, a slider is fixedly installed at the bottom end of the moving frame, and a guide rail is slidably installed on the slider. The guide rail is fixedly installed on the installation frame. An electric telescopic rod is arranged on one side of the moving frame far away from the positioning seat. The electric telescopic rod is fixedly installed on the installation frame, and the power output end of the electric telescopic rod is fixedly installed with a push plate. The push plate is fixedly installed on the side wall of the moving frame.

[0012] The beneficial effects of this utility model are that the design scheme of this utility model uses a roller conveyor assembly to transport the flywheel into the body of the laser marking machine. At this time, the positioning column 17 rises upward and is located on the front side of the flywheel conveying direction. The positioning column 17 blocks the flywheel and centers it so that the center hole of the flywheel can be aligned with the air shaft 11. At this time, the positioning seat 10 rises upward and the air shaft 11 is inserted into the center hole of the flywheel to fix the flywheel. After marking is completed, the air shaft 11 releases the flywheel, and the positioning seat 10 and the positioning column 17 descend in sequence. The roller conveyor assembly continues to transport the flywheel forward, thereby completing the loading and unloading of the flywheel for marking. During the loading and unloading process of the flywheel, no worker is required to position the flywheel, which helps to improve the marking efficiency. Attached Figure Description

The outer end of the conveying rollers 5 in the interval section 6 is rotatably installed on the conveying bracket 4 through a bearing, and the other end is fitted with a bearing seat. The bearing seat is fixedly installed on the mounting frame 3. The positioning seat 10 and the material blocking assembly are both located inside the interval section 6 and are bypassed by the interval section 6, so that the material blocking assembly and the positioning seat 10 can pass through the conveying rollers 5 to position the flywheel.

[0025] In this embodiment, adjacent conveying rollers 5 are connected to each other by a sprocket and chain assembly 7. A motor mounting bracket 8 is fixedly installed at the bottom of the conveying support 4, and a drive motor 9 is fixedly installed on the motor mounting bracket 8. The power output shaft of the drive motor 9 is connected to any group of conveying rollers 5 through the sprocket and chain assembly 7. The drive motor 9 drives the conveying rollers 5 connected to it to rotate. Under the action of the sprocket and chain assembly 7, all the conveying rollers 5 on the conveying support 4 rotate synchronously to realize the conveying of the flywheel.

[0026] In this embodiment, a connecting platform 101 is provided at the bottom end of the positioning seat 10. A plurality of groups of first guide rods 12 are slidably mounted on the connecting platform 101. Preferably, the number of the first guide rods 12 is two. The first guide rods 12 are fixedly mounted on the mounting frame 3. A first cylinder 13 is fixedly mounted at the bottom of the mounting frame 3. The power output end of the first cylinder 13 is fixedly connected to the bottom of the positioning seat 10. The positioning seat 10 is driven by the first cylinder 13 to lift and lower along the first guide rods 12, so that the air shaft 11 on the positioning seat 10 is inserted into the central hole of the flywheel, and the flywheel is fixed by the air shaft 11.

[0027] In this embodiment, the material blocking assembly includes a moving frame 14. The moving frame 14 is in a "U" shape structure. Two groups of second guide rods 15 are slidably mounted on the top plate of the moving frame 14. The top ends of the second guide rods 15 are fixedly mounted with a mounting plate 16. Positioning columns 17 are fixedly mounted at both ends of the mounting plate 16. A second cylinder 18 is fixedly mounted at the bottom of the top of the moving frame 14. The power output shaft of the cylinder is fixedly connected to the mounting plate 16. The mounting plate 16 is driven by the second cylinder 18 to lift and lower along the second guide rods 15, so that the positioning columns 17 rise upward. The positioning columns 17 are located on the front side of the flywheel conveying direction. The flywheel is blocked by the positioning columns 17, and at the same time, the flywheel is centered, so that the central hole of the flywheel can be aligned with the air shaft 11.

[0028] In this embodiment, a slider 19 is fixedly mounted at the bottom end of the moving frame 14. A guide rail 20 is slidably mounted on the slider 19.

The push plate 22 is fixedly mounted on the side wall of the moving frame 14. The distance between the moving frame 14 and the positioning seat 10 is adjusted by the electric telescopic rod 21 to position flywheels with different diameters. Before the formal processing starts, the flywheel to be processed is fixed on the positioning seat 10. The electric telescopic rod 21 is started. The electric telescopic rod 21 drives the moving frame 14 to move, so that the positioning column 17 abuts against the side wall of the flywheel. At this time, the push rod of the electric telescopic rod 21 stops and maintains the current position, thus completing the position adjustment of the positioning column 17.

[0029] In use, the flywheel to be processed is placed on the conveying roller 5 for conveying. Driven by the drive motor 9, the conveying roller 5 conveys the flywheel into the laser marking machine body 1. At this time, the second cylinder 18 drives the positioning column 17 to rise. The positioning column 17 is located in front of the flywheel conveying direction. The positioning column 17 blocks the flywheel and centers it so that the center hole of the flywheel can be aligned with the air shaft 11. At this time, the first cylinder 13 drives the positioning seat 10 to rise. The air shaft 11 is inserted into the center hole of the flywheel and the flywheel is fixed by the air shaft 11. Then, the laser marking head set in the laser marking machine body 1 marks the flywheel.
