Description

Technical Field

[0001] This utility model relates to the technical field of automobile flywheel processing equipment, specifically to a flipping structure for an automobile cast iron flywheel. Background Technology

[0002] The cast iron flywheel in an automobile is a disc-shaped component at the rear end of the engine crankshaft. It has a large moment of inertia and is mainly used to store energy, balance speed fluctuations, and connect the transmission system. Cast iron flywheels are usually made of gray cast iron or ductile iron. Their structure includes a steel disc that engages with the clutch and an inertial disc that stores energy. Some models also have a gear ring to cooperate with the starter motor.

[0003] A search revealed application CN202223122975.0: "An automatic flipping machine and an automotive processing production line," wherein the automatic flipping machine includes a column and a bearing housing, a parts bin is mounted on the column, the parts bin is a rectangular parallelepiped open at one end and symmetrically equipped with a first short shaft and a second short shaft on both sides, the first short shaft being supported on the column by bearings… This utility model not only improves the efficiency and reliability of flywheel assembly processing but also reduces manual labor intensity. However, some shortcomings still exist:

[0004] When the cast iron flywheel enters the conveyor roller in the parts bin, if the cast iron flywheel deviates, there is a safety hazard that it may fall off the roller conveyor belt when it completes its rotation and enters the next process. Furthermore, there is no effective limit on the cast iron flywheel during the rotation process driven by the parts bin, so there is a risk that the cast iron flywheel may shift or even fall off during the rotation process. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a flipping structure for a cast iron flywheel in automobiles.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A flipping structure for a cast iron flywheel in an automobile includes:

[0008] A flip frame and fixed frames symmetrically arranged on both sides of the flip frame. Roller seat one is symmetrically installed on the lower inner wall of the flip frame, and roller seat two is symmetrically installed on the upper inner wall of the flip frame. A reduction motor is installed on the fixed frame. The output end of the reduction motor is fixedly connected to the outer wall of the flip frame. The upper and lower outer walls of the flip frame are provided with pressing mechanisms to limit the surface of the cast iron flywheel.

[0009] The upper and lower inner walls of the flip frame are equipped with a centering mechanism that limits the side of the cast iron flywheel.

[0010] Preferably, the pressing mechanism includes an electric push rod fixed to the outer wall of the flip frame via a connecting frame, the movable end of the electric push rod being fixedly connected to an I-shaped plate, and a plurality of pressing plates being symmetrically fixedly connected to the I-shaped plate.

[0011] Preferably, the centering mechanism includes two sets of guide rails symmetrically installed on the inner wall of the flipping frame. Each set of guide rails has two rails, and each guide rail has a slider that is slidably engaged. Adjacent sliders are fixedly connected to a connecting plate, and centering rollers are symmetrically fixedly connected to the connecting plate.

[0012] Preferably, a rack one is fixedly connected to one of the connecting plates, a rack two is fixedly connected to the other connecting plate, and a gear is rotatably connected to the inner wall of the flip frame. The gear meshes with rack one and rack two.

[0013] Preferably, the centering mechanism further includes an electric push rod II fixedly connected to the outer wall of the flipping frame, the movable end of the electric push rod II passing through the side wall of the flipping frame and fixedly connected to the adjacent connecting plate.

[0014] Preferably, each of the pressing plates is slidably disposed through the inner wall of the flip frame, and a rubber sleeve is fixedly connected to the end of the pressing plate away from the I-beam.

[0015] This utility model has the following beneficial effects:

[0016] 1. By setting up components such as a flipping frame, a reduction motor, and a fixing frame, this flipping structure can be installed between two processes. The flipping frame is rotated alternately in both directions to flip the cast iron flywheel on the production line. The flipping operation of the cast iron flywheel has good continuity and improves the processing efficiency of the cast iron flywheel.

[0017] 2. By setting up components such as electric push rod, pressing plate and rubber sleeve, the rubber sleeve on multiple pressing plates and the upper surface of the cast iron flywheel are made to abut against each other to form a stop and limit, so as to prevent the cast iron flywheel from shifting when it is flipped.

[0018] 3. By setting up structures such as electric push rod II, centering roller and connecting plate, the two sets of centering rollers move closer to each other and push against the side of the cast iron flywheel, so that the cast iron flywheel completes the centering and positioning inside the flipping frame before flipping, which facilitates the smooth entry of the cast iron flywheel in the subsequent flipping frame into the next process.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-4 A flipping structure for a cast iron flywheel in an automobile, comprising:

[0026] The rotating frame 1 and the fixed brackets 10 symmetrically arranged on both sides of the rotating frame 1. The roller seat 1 3 is symmetrically installed on the lower inner wall of the rotating frame 1, and the roller seat 2 4 is symmetrically installed on the upper inner wall of the rotating frame 1. Both roller seat 1 3 and roller seat 2 4 are composed of transmission rollers and frame structures, which are existing technologies and will not be described in detail here. A geared motor 2 is installed on one of the fixed brackets 10. The geared motor 2 is existing technology and can change the rotation direction of the motor output end. It has a self-locking function after rotating a certain angle. The output end of the geared motor 2 is fixedly connected to the outer wall of the rotating frame 1. The upper and lower outer walls of the rotating frame 1 are provided with pressing mechanisms to limit the surface of the cast iron flywheel.

[0027] The upper and lower inner walls of the flip frame 1 are equipped with a centering mechanism that limits the side of the cast iron flywheel.

[0028] The pressing mechanism includes an electric push rod 6 fixed to the outer wall of the flip frame 1 via a connecting frame 5. The electric push rod 6 is a DTZ-100 model. An I-shaped plate 7 is fixedly connected to the movable end of the electric push rod 6. Multiple pressing plates 8 are symmetrically fixedly connected to the I-shaped plate 7.

[0029] The centering mechanism includes two sets of guide rails 13 symmetrically installed on the inner wall of the flip frame 1 (combined with...) Figure 2 , Figure 3 and Figure 4 As shown), each set of guide rails 13 consists of two rails, and each guide rail 13 is slidably fitted with a slider 14. The two adjacent sliders 14 are fixedly connected to a connecting plate 12. The connecting plate 12 is symmetrically fixedly connected with a centering roller 18. The centering roller 18 passes through the position between the two drive rollers in the roller seat 1 (roller seat 2 4), ensuring that it will not interfere with the roller seat 1 (roller seat 2 4) during movement. In the initial state, the centering roller 18 is at the outermost position of the roller seat 1 (roller seat 2 4) and will not interfere with the cast iron flywheel entering the flip frame 1.

[0030] Each centering mechanism has a connecting plate 12 on which a rack 15 is fixedly connected (connected to the connecting plate 12). Figure 4 As shown), a rack 16 is fixedly connected to another connecting plate 12, and a gear 17 is rotatably connected to the inner wall of the flip frame 1. The gear 17 is meshed with the rack 15, and the gear 17 is meshed with the rack 16.

[0031] The centering mechanism also includes an electric push rod 11 fixedly connected to the outer wall of the flip frame 1 (in conjunction with...). Figure 1 and Figure 4 As shown), the electric push rod 2 11 is existing technology. The movable end of the electric push rod 2 11 passes through the side wall of the flip frame 1 and is fixedly connected to the adjacent connecting plate 12.

[0032] Each pressing plate 8 is slidably set through the inner wall of the flip frame 1. In the initial state, the pressing plate 8 will not exceed the height of the roller seat 3 (roller seat 4). The end of the pressing plate 8 away from the I-shaped plate 7 is fixedly connected to a rubber sleeve 9. After the rubber sleeve 9 comes into contact with the cast iron flywheel, it plays a role in anti-slip and protection.

[0033] In this invention, the flipping structure is installed between the conveyor rollers of two processes on the automotive cast iron flywheel processing production line via multiple external support columns. After the previous process completes the processing of the upper surface of the automotive cast iron flywheel, the automotive cast iron flywheel enters from one side of the flipping frame 1 onto the roller seat 3 inside the flipping frame 1 (in conjunction with...). Figure 1 and Figure 2 As shown), at this time, the electric push rod 6, which is away from the roller seat 3, is turned on. The movable end of the electric push rod 6 drives the I-shaped plate 7, which is fixedly connected to it, to move downward. Then the I-shaped plate 7 will drive multiple pressing plates 8 to move downward synchronously for a distance until the rubber sleeves 9 on the multiple pressing plates 8 and the upper surface of the cast iron flywheel come into contact and form a stop.

[0034] Next, the electric push rod 11 is activated. The movable end of the electric push rod 11 drives the connecting plate 12, which is fixedly connected to it, to move (e.g., Figure 4As shown, the connecting plate 12 drives the two centering rollers 18 fixedly connected to it to move synchronously to the middle position of the flipping frame 1. The connecting plate 12 also drives the rack 15 fixedly connected to it to move. The rack 15 drives the rack 16 fixedly connected to it to move in the opposite direction through the gear 17. Then the rack 16 will drive the connecting plate 12 fixedly connected to it to move in the opposite direction. The connecting plate 12 drives the two centering rollers 18 fixedly connected to it to move in the opposite direction. Then the two sets of centering rollers 18 will push the side of the cast iron flywheel after abutting against each other, so that the cast iron flywheel completes the centering and positioning inside the flipping frame 1 before flipping, which facilitates the cast iron flywheel in the flipping frame 1 to smoothly enter the next process.

[0035] Finally, the geared motor 2 is turned on. The output of the geared motor 2 drives the rotating frame 1, which is fixedly connected to it, to rotate a certain angle, so that the cast iron flywheel inside the rotating frame 1 rotates synchronously. It should be noted that the rotation angle of the rotating frame 1 can be slightly greater than 180 degrees. Then, the limit on the cast iron flywheel is released by controlling the electric push rod 6 and the electric push rod 11, so that the cast iron flywheel can enter the next process.

[0036] The geared motor 2 is a forward and reverse rotating motor. When the next cast iron flywheel enters the flipping frame 1, the operation method is as described above, but at this time the output end of the geared motor 2 is rotated in the reverse direction to complete the flipping operation of the cast iron flywheel. The flipping operation of the cast iron flywheel has good continuity and improves the processing efficiency of the cast iron flywheel.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
