Description

Technical Field

[0001] This invention belongs to the field of machining, and specifically relates to a flipping device and method for assembling large frames. Background Technology

[0002] When assembling a large frame, the piston connecting rod and cylinder head installation machine needs to rotate the frame by 45°, and after the oil pan is installed, the frame needs to be rotated 180°. During assembly on the production line, the rotation is usually done by a turning machine. However, when assembling or repairing the frame outdoors, it is difficult to achieve a 45° rotation or a 180° rotation. This is because the existing assembly trolley is designed with a sliding track and relies on the track force to prevent tipping. When used off-track, tipping is likely to occur, resulting in a low safety factor. The entire turning machine is a fixed ground structure that cannot be moved and requires electric power to operate. Therefore, it cannot be used when assembling or repairing in harsh outdoor environments. Summary of the Invention

The left base frame (2) and the right base frame (3) are respectively fixedly connected to the two ends of the two wheel frame bodies along their length. A circular frame (4) is rotatably disposed between the left base frame (2) and the right base frame (3) for bearing and driving the frame to be assembled to rotate; the circular frame (4) includes a circular frame body (4-1), a left circular ring (4-2) fixed to one end of the circular frame body (4-1) and a right circular ring (4-3) fixed to the other end of the circular frame body (4-1); the left circular ring (4-2) and the right circular ring (4-3) are rotatably supported in the left base frame (2) and the right base frame (3) respectively; Among them, multiple stop plates (4-4) are evenly arranged circumferentially on the outer surface of the left ring (4-2) and / or the right ring (4-3); a positioning and fixing mechanism (4-5) is correspondingly provided on the left base frame (2) and / or the right base frame (3), and the positioning and fixing mechanism (4-5) has a fixing pin (4-5-2) that can be selectively engaged between the stop plates (4-4) to lock the ring frame (4) at a specific angle.

[0005] Furthermore, the left ring (4-2) is a split structure, including a separable upper ring (4-2-1) and a lower ring (4-2-2), which are detachably connected by at least one locking connection mechanism (4-2-3).

[0006] Furthermore, the locking connection mechanism (4-2-3) includes a hinge bolt seat (4-2-4) disposed on the upper ring (4-2-1), a connecting seat (4-2-6) disposed on the lower ring (4-2-2), and a connecting pin (4-2-5) connecting the two.

[0007] Furthermore, an external gear ring (4-3-1) is fixedly provided on the outer circumference of the right ring (4-3); a handle (3-1) and a pinion (3-2) that is connected to the handle (3-1) are installed on the right base frame (3), and the pinion (3-2) meshes with the external gear ring (4-3-1).

[0008] Furthermore, the ring frame (4) can be locked at rotational positions every 45°.

[0009] Furthermore, the circular frame body (4-1) includes two parallel crossbeams (4-1-1), each crossbeam (4-1-1) is provided with a left support plate (4-1-2) and a right support plate (4-1-3) for placing and fixing the frame to be assembled; the two ends of the crossbeam (4-1-1) are fixedly connected to the left circular ring (4-2) and the right circular ring (4-3) respectively.

[0010] Furthermore, the circular frame body (4-1) also includes a frame structure connecting the left circular ring (4-2) and the right circular ring (4-3). The frame structure is constructed by welding an upper steel pipe (4-1-4), a lower steel pipe (4-1-5), and a reinforcing rib plate (4-1-6) connecting the two.

[0011] Furthermore, the wheel frame body includes a left groove steel frame (1-1) and a right groove steel frame (1-2), and the wheel (1-3) is installed between the two.

It integrates the working principle of the assembly trolley and adopts a wheeled design for easy movement. The basic structure is designed as a rotatable structure to meet the assembly requirements of rotating 45° and flipping 180°. Considering safety issues, the axial center line of the frame itself is nearly coincident with the center line of the flipping frame tooth ring to meet the flipping requirements of non-assembly line, achieving a safe and labor-saving effect.

[0015] This invention is easy to move, facilitates the assembly and hoisting of the frame, and the frame can be flipped during assembly and fixed in position according to the flipping angle of the frame.

The positioning and fixing mechanism can lock the left circular ring to the left base frame and the right circular ring to the right base frame, facilitating positioning at different angles according to the needs of frame assembly. During frame assembly, the frame needs to rotate at different angles such as 45° and 180°. Therefore, stop plates are evenly arranged along the circumference of both the left and right circular rings. When the frame rotates 45° with the circular frame, it can be locked in the middle of the stop plates on the left and right circular rings by the positioning and fixing mechanism, thus locking the entire circular frame.

Detailed Implementation

[0018] To make the objectives, contents, and advantages of the present invention clearer, the specific embodiments of the present invention will be described in further detail below.

[0019] The present invention proposes a large frame assembly flipping device, including a wheel frame (1), a left base frame (2), a right base frame (3) and a ring frame (4). The wheel frame (1) includes two parallel wheel frame bodies. One end of the wheel frame body is provided with the left base frame (2) and the other end of the wheel frame body is provided with the right base frame (3). The ring frame (4) is located between the left base frame (2) and the right base frame (3) and can rotate. The left base frame (2) and the right base frame (3) are both provided with positioning and fixing mechanisms (4-5). The circular frame (4) includes a circular frame body (4-1), a left circular ring (4-2) and a right circular ring (4-3). The left circular ring (4-2) and the right circular ring (4-3) are respectively set at both ends of the circular frame body (4-1). Stop plates (4-4) are evenly arranged along the circumference on both the left circular ring (4-2) and the right circular ring (4-3). The left circular ring (4-1) is set in the left base frame (2), and the right circular ring (4-2) is set in the right base frame (3). Specifically, the number of stop plates 4-4 can be set arbitrarily according to the rotation angle requirements, such as 8, 12, 16, etc. The stop plate 4-4 has a locking groove in the middle. The left ring 4-1 is set in the left base frame 2, and the right ring 4-2 is set in the right base frame 3. The positioning and fixing mechanism 4-5 includes a stop seat 4-5-1 and a fixing pin 4-5-2. The two ends of the fixing pin 4-5-2 are fixed on the stop seat 4-5-1, and the middle is locked in the middle of the stop plate 4-4. The positioning and fixing mechanism 4-5 facilitates the fixed positioning of the frame after it rotates a certain angle with the circular frame 4, ensuring the safety and accuracy of the circular frame 4 after it rotates to a certain position. The positioning and fixing is achieved by using a positioning pin connection. The two ends of the fixing pin 4-5-2 are fixed to the stop seat 4-5-1, and the middle is locked in the middle of the stop plate 4-4. The positioning and fixing mechanism 4-5 can lock the left circular ring 4-2 to the left base frame 2 and the right circular ring 4-3 to the right base frame 3, which facilitates positioning at different angles according to the needs of the frame assembly. During the frame assembly process, the frame needs to rotate at different angles such as 45° and 180°. Therefore, stop plates 4-4 are evenly arranged along the circumference on both the left circular ring 4-2 and the right circular ring 4-3. When the frame rotates 45° with the circular frame, the fixing pin 4-5-2 on the positioning and fixing mechanism 4-5 can be locked in the middle of the stop plates on the left and right circular rings, thereby locking the entire circular frame 4.

[0020] The left ring 4-2 is a split structure, comprising an upper ring 4-2-1 and a lower ring 4-2-2, which are connected by two locking mechanisms 4-2-3. Each locking mechanism 4-2-3 includes a hinge bolt seat 4-2-4 on the upper ring 4-2-1 and a connecting seat 4-2-6 on the lower ring 4-2-2. The hinge bolt seat 4-2-4 and the connecting seat 4-2-6 are connected by a connecting pin 4-2-5. The left ring 4-2 adopts a split ring structure, that is, the entire left ring is divided into two semi-circular rings. The two semi-circular rings are connected by the locking connection structure 4-2-3. When the frame is lowered into or lifted out of the frame, the upper ring 4-2-1 of the left ring 4-2 is removed. After the frame is lowered into or moved away from the crossbeam, the left ring 4-2 is reassembled and locked by the locking connection structure 4-2-3, which facilitates the hoisting of the frame.

[0021] A handle 3-1 is provided on the right base frame 3. The handle 3-1 drives the large gear ring 4-3-1 on the right circular ring 4-2 to rotate through the small gear 3-2. The right base frame is equipped with a handle and a small gear, and the right circular ring is equipped with a large gear ring. The large and small gears mesh and drive each other. When in use, turning the handle drives the small gear to rotate, which in turn drives the large gear ring to rotate. The right circular ring rotates, thereby achieving the purpose of rotating the entire circular ring frame.

[0022] The wheel frame body includes a left slot steel frame 1-1 and a right slot steel frame 1-2, with a wheel 1-3 fixed between the left slot steel frame 1-1 and the right slot steel frame 1-2. The wheel frame is equipped with wheels, allowing the entire tilting frame to be moved freely, taking into account the uncertainty of the installation location and the weight of the tilting frame itself.

[0023] To further ensure the safety and stability of the frame during rotation, the circular frame body 4-1 includes two symmetrically arranged crossbeams 4-1-1 and a frame welded to the left circular ring 4-2 and the right circular ring 4-3. The two ends of the crossbeams 4-1-1 are respectively welded to the frame. The crossbeams 4-1-1 are provided with a left support plate 4-1-2 and a right support plate 4-1-3 for placing the frame. The frame is welded from an upper steel pipe 4-1-4 and a lower steel pipe 4-1-5. A reinforcing rib plate 4-1-6 is welded between the upper steel pipe 4-1-4 and the lower steel pipe 4-1-5.

[0024] Work process: When this flipping device is in operation, first loosen the locking connection mechanism 4-2-3 of the left ring 4-2, remove the upper ring 4-2-1 of the left ring 4-2, then lift the frame and place it on the left support plate 4-1-2 and right support plate 4-1-3 of the crossbeam 4-1-1. Then fix the frame on the left support plate 4-1-2 and right support plate 4-1-3 with bolts and nuts. When the frame needs to be rotated during the assembly process, simply turn the handle 3-1, which drives the large gear ring 4-3-1 on the right ring 4-3 to rotate through the small gear 3-2, and the ring frame 4 rotates, thereby realizing the rotation of the frame. When the frame rotates to the corresponding angle, the fixing pins 4-5-2 on the positioning and fixing mechanism 4-5 are fixed at both ends on the stop seat (4-5-1) and in the middle of the stop plate (4-4), thereby locking the entire ring frame 4 and performing the corresponding assembly work.

[0025] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
