Description

Technical Field

[0001] This utility model relates to a flipping machine. Background Technology

[0002] Some large components, such as heat exchangers, need to be rotated 90° during processing before assembly or testing. Due to their large size and weight, they cannot be rotated manually and require mechanical equipment. For example, the invention patent CN116081252A, published on May 9, 2023, discloses a transformer rotating machine. It uses a sprocket at the output end of a motor to control the chain on the outer circumferential wall of one of the arc-shaped plates, thereby driving the entire arc-shaped rotating frame to rotate 90°. A sprocket directly drives the chain in the middle to rotate, which in turn drives the entire arc-shaped rotating frame to rotate. However, this method has relatively poor stability. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a turning machine that improves the turning stability of the turning machine.

[0004] To achieve the above objectives, one technical solution adopted by this utility model is: a flipping machine, including a frame, an arc-shaped flipping frame, and a motor that drives the arc-shaped flipping frame to rotate on the frame. The motor is fixed on the frame. The arc of the arc-shaped flipping frame is a 3 / 4 circle. The arc-shaped flipping frame has a product mounting plate, on which a product to be flipped is mounted. The arc-shaped flipping frame has a circular arc bottom surface, and transmission chains are respectively arranged on both sides of the circular arc bottom surface. A transmission shaft is arranged on the frame. Both ends of the transmission shaft are rotatably mounted on the frame through bearings. A secondary sprocket is fixedly arranged in the middle of the transmission shaft, and driven sprockets are fixedly arranged at both ends. A main sprocket is arranged on the output shaft of the motor. A synchronous chain is meshed on the main sprocket and the secondary sprocket. The two driven sprockets mesh with the two transmission chains respectively. Guide wheels are arranged at the front and rear positions on both sides of the frame, and the guide wheels on the same side are distributed at the front and rear ends of the transmission shaft.

[0005] The beneficial effect of this utility model of the flipping machine is that it uses a motor as the driving source, and then achieves transmission through the cooperation of the main sprocket, the auxiliary sprocket, the synchronous chain, the transmission shaft, and the driven sprockets at both ends. Then, by driving the transmission chains on both sides of the arc bottom surface, it drives the entire arc-shaped flipping frame to flip 90°. Compared with a sprocket directly driving a chain to flip the entire arc-shaped flipping frame, it is more stable during the flipping process.

[0006] Preferably, the product mounting plate has an L-shaped structure and is provided with multiple pairs of fixing posts. The fixing posts are matched with the shape of the product to be flipped and are used to install the product.

[0007] Preferably, each pair of fixing posts includes two fixing posts, and each fixing post has a slider plate at its bottom. The two slider plates are slidably mounted on a guide rail, which is fixedly mounted on the product mounting plate. Multiple guide rails are arranged parallel to each other. The slider plates are provided with locking bolts for securing the slider plates to the guide rails. The fixing posts are adjustablely mounted on the guide rails, facilitating the installation of the product to be flipped.

[0008] Preferably, both ends of the product mounting plate extend into arc-shaped flip frames, and the back of the product mounting plate extending from the arc-shaped flip frames is provided with reinforcing ribs. The reinforcing ribs are plate-shaped, and the side of the reinforcing ribs facing the arc-shaped bottom surface is an arc surface, which fits the arc-shaped bottom surface.

[0009] Preferably, the product mounting plate includes mutually perpendicular support plates and side plates installed on the sides of each support plate. The support plates are locked and fixed to the arc-shaped flipping frame, some of the side plates are locked and fixed to the sides of the support plates, and the remaining side plates are locked and fixed to the arc-shaped flipping frame. The product mounting plate is assembled from disassembled side plates and support plates, ensuring that the reinforcing ribs can be secured to the arc-shaped bottom surface.

[0010] Preferably, a front limiting block and a rear limiting block are fixedly installed on the frame, and the front limiting block and the rear limiting block are used to support the end of the product mounting plate extending from the arc-shaped flip frame. When the arc-shaped flip frame flips to the correct position, it is limited by one of the limiting blocks; when the arc-shaped flip frame flips in the opposite direction, it is limited by the other limiting block.

[0011] Preferably, both the front and rear limit blocks are equipped with proximity switches. The proximity switches are used to monitor whether the arc-shaped tilting frame has tilted into place. Attached Figure Description

[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0023] See Figures 1 to 5 As shown, this embodiment discloses a flipping machine, including a frame 10, an arc-shaped flipping frame 20, and a motor 30 that drives the arc-shaped flipping frame 20 to rotate on the frame 10. The motor 30 is fixed on the frame 10. The arc of the arc-shaped flipping frame 20 is a 3 / 4 circle, and a vertical mounting surface is formed on the arc-shaped flipping frame 20. A product mounting plate 40 is provided on the vertical mounting surface of the arc-shaped flipping frame 20, and a product to be flipped is mounted on the product mounting plate 40. The arc-shaped flipping frame 20 has an arc-shaped bottom surface 21, and a transmission chain 22 is respectively provided on both sides of the arc-shaped bottom surface 21. A transmission shaft is provided on the frame 10. 31. Both ends of the drive shaft 31 are rotatably mounted on the frame 10 via bearings 32. A secondary sprocket 33 is fixedly installed in the middle of the drive shaft 31. In this embodiment, the secondary sprocket 33 is close to one end. Driven sprockets 34 are fixedly installed at both ends of the drive shaft 31. The output shaft of the motor 30 is provided with a main sprocket 35. A synchronous chain 36 is meshed on the main sprocket 35 and the secondary sprocket 33. The two driven sprockets 34 are respectively meshed with two drive chains 22. Guide wheels 11 are provided at the front and rear positions on both sides of the frame 10. The guide wheels 11 on the same side are distributed at the front and rear ends of the drive shaft 31.

[0024] The product mounting plate 40 has an L-shaped structure and is provided with multiple pairs of fixing posts 41. The fixing posts 41 are matched with the shape of the product to be flipped and are used to mount the product. Figure 1 , Figure 2As shown, each pair of fixing posts 41 includes two fixing posts 41. Each fixing post 41 has a slider plate 42 at its bottom. The two slider plates 42 are slidably mounted on a guide rail 43, which is fixedly mounted on the product mounting plate 40. Multiple guide rails 43 are arranged parallel to each other. The slider plate 42 is provided with locking bolts 44 for securing it to the guide rail 43. The position of the fixing post 41 on the guide rail 43 can be adjusted, thereby adjusting the distance between the two fixing posts 41.

[0025] like Figure 1 , Figure 2 As shown, both ends of the product mounting plate 40 extend into arc-shaped flip frames 20. Reinforcing ribs 45 are provided on the back of the product mounting plate 40 extending into the arc-shaped flip frames 20. The reinforcing ribs 45 at both ends are plate-shaped and are used to limit the product mounting plate 40 to both ends of the arc-shaped bottom surface 21. The reinforcing ribs 45 improve the connection strength between the product mounting plate 40 and the arc-shaped flip frames 20. Figure 1 As shown, the reinforcing rib 45 is fixed to the bottom of the product mounting plate 40. The side of the reinforcing rib 45 facing the arc bottom surface 21 is an arc surface 46, and the arc surface 46 fits the arc bottom surface 21.

[0026] like Figure 1 , Figure 2 As shown, the product mounting plate 40 includes mutually perpendicular support plates 40a and side plates 40b installed on the sides of each support plate 40a. The support plates 40a are locked and fixed to the arc-shaped flip frame 20, some side plates 40b are locked and fixed to the sides of the support plates 40a, and the remaining side plates 40b are locked and fixed to the arc-shaped flip frame 20. When installing the product mounting plate 40, first install the two support plates 40a on the arc-shaped flip frame 20, with the arc bottom surface 21 installed along the arc surface 46, and then lock the side plates 40b onto the support plates 40a and the arc-shaped flip frame 20. In this embodiment, the product mounting plate 40 is assembled by disassembling the side plates 40b and the support plates 40a, ensuring that the reinforcing ribs 45 can be installed.

[0027] A front limit block 12 and a rear limit block 13 are fixedly mounted on the frame 10. These blocks support the end of the product mounting plate 40 extending from the arc-shaped tilting frame 20. When the arc-shaped tilting frame 20 is tilted into position, it is stopped by one of the limit blocks; when it is tilted in the opposite direction, it is stopped by the other limit block. Both the front limit block 12 and the rear limit block 13 are equipped with proximity switches 14. These switches monitor whether the arc-shaped tilting frame 20 has tilted into position.

[0028] The working principle of this embodiment is as follows:

[0029] Motor 30 drives the arc-shaped tilting frame 20 to tilt until one support plate 40a is horizontal and the other support plate 40a is vertical. At the same time, the rear limit block 13 limits the arc-shaped tilting frame 20. Operators use heavy equipment such as cranes to install the product to be tilted onto the fixed column 41. After installation, motor 30 starts, the main sprocket 35 rotates, and drives the auxiliary sprocket 33 to rotate through the synchronous chain 36. This, in turn, drives the drive shaft 31 to rotate around its own central axis. The driven sprockets at both ends of the drive shaft 31... As the driven sprocket 34 rotates, the arc-shaped flipping frame 20 rotates along the guide wheels 11 on both sides until it is stopped by the front limit block 12. The proximity switch 14 of the front limit block 12 senses that the arc-shaped flipping frame 20 has flipped into place and controls the motor 30 to stop running. After the product to be flipped is assembled or inspected, it is directly unloaded. The motor 30 rotates in the opposite direction, driving the arc-shaped flipping frame 20 to rotate 90° in the opposite direction. It is then stopped again by the rear limit block 13 and is in the state of waiting to be loaded.
