Description

Technical Field

[0001] This utility model relates to the field of railway EMU workpiece maintenance technology, and in particular to a workpiece horizontal flipping device. Background Technology

[0002] In modern logistics and manufacturing, pallets play an irreplaceable and crucial role as the core medium connecting static goods with dynamic circulation. Essentially, they are a mobile cargo platform that transforms goods that were originally placed on the ground and lacked flexibility into mobile goods that can be moved at any time, providing efficient and convenient solutions for loading, unloading, handling, and storage.

[0003] However, most existing pallet technologies are single-function, only capable of carrying and transporting goods, and cannot adjust the posture of workpieces during transport. Currently, workpiece rotation and other positional changes must rely on independent equipment such as external flipping machines and dedicated rotary tables. This not only leads to complex processes and rigid production line layouts, reducing space utilization, but also significantly increases equipment costs and operation time due to frequent workpiece transfers in processes such as maintenance, becoming a bottleneck restricting overall efficiency improvement.

[0004] Therefore, there is an urgent need to provide a workpiece horizontal flipping device that combines flipping and transportation functions to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a workpiece horizontal flipping device that combines flipping and transportation functions, simplifies the operation process, and improves space utilization.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A workpiece horizontal flipping device, comprising:

[0008] The base plate is placed on the transmission mechanism and can move along the upper edge of the transmission mechanism in a first direction;

[0009] Two brackets are spaced apart on the top surface of the base plate along the first direction;

[0010] Multiple support wheels are respectively disposed on the two brackets to support the workpiece;

[0011] A transmission assembly includes a transmission component, a driving wheel, and a driven wheel. The transmission component is rotatably mounted on the bracket. The driving wheel and the transmission component are coaxially arranged. The driven wheel and the support wheel are coaxially arranged, and the driven wheel is throttlely connected to the driving wheel.

[0012] The driving mechanism includes a lifting drive, a rotating drive, and a rotating component. The rotating component is connected to the transmission component and has a rotating groove at its bottom. The lifting drive is mounted on the transmission mechanism, and the rotating drive is connected to the output end of the lifting drive. When the base plate moves to a preset work position, the lifting drive can drive the rotating drive to rise, so that the output end of the rotating drive inserts into the rotating groove. The rotating drive can then drive the rotating component to rotate, thereby causing the transmission component to rotate, which in turn drives the driving wheel to rotate, which in turn drives the driven wheel to rotate, and then drives the support wheel to rotate, so that the workpiece can be flipped horizontally.

[0013] Preferably, the rotating component is vertically mounted on the bracket, the transmission component is vertically mounted on the base plate, the rotating component is provided with a first conical head, and the transmission component is provided with a second conical head, the first conical head and the second conical head meshing with each other.

[0014] Preferably, the driving wheel and the driven wheel are meshed with each other or connected by a transmission belt.

[0015] Preferably, the bracket is a hollow structure with an open top, and both the driving wheel and the driven wheel are disposed inside the bracket.

[0016] Preferably, the bracket has a placement groove at the top, the bottom of the workpiece is located in two of the placement grooves, and the bracket has mounting grooves connected to the placement grooves on both sides opposite to each other along the second direction. A pair of support wheels are symmetrically installed on the outer wall of each mounting groove opposite to each other along the first direction. The driven wheel is located in one of the mounting grooves and is coaxially connected to the two support wheels on the mounting groove. The second direction is perpendicular to the first direction.

[0017] Preferably, the workpiece horizontal flipping device further includes a detector mounted on the bracket and configured to detect whether the workpiece is placed on the bracket.

[0018] Preferably, the transmission mechanism includes two spaced-apart transmission rails, and the drive mechanism further includes a fixed base located between and connected to the two transmission rails, with the lifting drive component mounted on the fixed base.

[0019] Preferably, the rotating groove is a groove with a non-circular cross-section.

[0020] Preferably, the lifting drive component is a cylinder or an electric push rod, and the rotation drive component is a rotary cylinder or a servo motor.

[0021] The beneficial effects of this utility model are:

[0022] This invention provides a workpiece horizontal flipping device. When the workpiece-carrying flipping device moves to a preset station with the base plate, the lifting drive component fixed on the transmission mechanism immediately activates, pushing the rotating drive component upward so that its output end is precisely inserted into the rotating groove at the bottom of the rotating component. Subsequently, the rotating drive component starts, driving the transmission component of the transmission assembly to rotate through the rotating component, thereby driving the coaxially connected drive wheel to rotate, and transmitting power to the support wheel through the driven wheel. Finally, the rotation of the support wheel drives the workpiece placed in the bracket placement groove to achieve horizontal flipping through friction. This flipping device combines workpiece conveying and posture adjustment functions. From entering the conveyor line to completing the flipping, the workpiece does not need to leave this flipping device, nor does it need to undergo additional transfer, positioning, and clamping processes to an independent flipping device, simplifying the operation process, improving maintenance efficiency, and improving space utilization by reducing the need for dedicated rotating stations.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0038] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0039] like Figures 1-4As shown, this utility model provides a workpiece horizontal flipping device, comprising a base plate 1, a bracket 2, support wheels 3, a transmission assembly 4, and a drive mechanism 5. The base plate 1 is placed on a transmission mechanism 100 and can move along a first direction on the transmission mechanism 100. Two brackets 2 are spaced apart on the top surface of the base plate 1 along the first direction. Multiple support wheels 3 are distributed on the two brackets 2 to support workpieces 200. The transmission assembly 4 includes a transmission component 41, a driving wheel 42, and a driven wheel 43. The transmission component 41 is rotatably mounted on the bracket 2. The driving wheel 42 and the transmission component 41 are coaxially arranged. The driven wheel 43 and the support wheels 3 are coaxially arranged, and the driven wheel 43 is throttle-connected to the driving wheel 42. The drive mechanism 5 includes a lifting drive component. 51. A rotary drive component 52 and a rotating component 53 are connected to a transmission component 41. The rotating component 53 has a rotating groove 530 at its bottom. A lifting drive component 51 is mounted on the transmission mechanism 100. The rotary drive component 52 is connected to the output end of the lifting drive component 51. When the base plate 1 moves to the preset work position, the lifting drive component 51 can drive the rotary drive component 52 to rise, so that the output end of the rotary drive component 52 inserts into the rotating groove 530. The rotary drive component 52 can drive the rotating component 53 to rotate, which in turn drives the transmission component 41 to rotate, thereby driving the drive wheel 42 to rotate, which in turn drives the driven wheel 43 to rotate, which in turn drives the support wheel 3 to rotate, so that the workpiece 200 can be flipped horizontally. See also Figure 1 The X direction is the first direction, and the Y direction is the second direction.

[0040] When the flipping device carrying the workpiece 200 moves to the preset station with the base plate 1, the lifting drive component 51 fixed on the transmission mechanism 100 immediately activates, pushing the rotary drive component 52 upward so that its output end is precisely inserted into the rotating groove 530 at the bottom of the rotating component 53. Subsequently, the rotary drive component 52 starts, driving the transmission component 41 of the transmission assembly 4 to rotate through the rotating component 53, thereby driving the drive wheel 42 coaxially connected to it to rotate, and transmitting power to the support wheel 3 through the driven wheel 43. Finally, the rotation of the support wheel 3 drives the workpiece 200 placed in the placement groove 20 of the bracket 2 to achieve horizontal flipping through friction. This flipping device integrates the functions of workpiece 200 conveying and posture adjustment. From entering the conveyor line to completing the flipping, the workpiece 200 does not need to leave this flipping device, nor does it need to go through additional transfer, positioning, and clamping processes to independent flipping equipment, simplifying the operation process, improving maintenance efficiency, and improving space utilization by reducing the setting of dedicated rotating stations.

[0041] Specifically, such as Figure 1 and Figure 2As shown, bracket 2 is a hollow structure with an open top, and both the driving wheel 42 and the driven wheel 43 are housed within bracket 2. The interior of bracket 2 is a semi-enclosed space, effectively isolating the driving wheel 42 and the driven wheel 43 from the external environment, preventing dust, debris, moisture, and other contaminants from entering the transmission system, and avoiding abnormal wear, jamming, or transmission slippage caused by contamination. At the same time, it also prevents accidental contact between operators or external objects and moving parts, providing dual protection for both operational safety and long-term stable operation of the transmission system.

[0042] Specifically, such as Figure 1 and Figure 2 As shown, the bracket 2 has a placement groove 20 on its top. The bottom of the workpiece 200 is located within two placement grooves 20. The bracket 2 has mounting grooves 21 on both opposite sides along a second direction, communicating with the placement grooves 20. A pair of support wheels 3 are symmetrically mounted on the outer wall of each mounting groove 21 facing away from each other along a first direction. A driven wheel 43 is located within one of the mounting grooves 21 and coaxially connected to the two support wheels 3 on the mounting groove 21. The second direction is perpendicular to the first direction. The bottom of the workpiece 200 is located within the two placement grooves 20, and combined with the symmetrically distributed support wheels 3 on the outer wall of the mounting grooves 21, a stable rectangular support area is formed. This resists the overturning moment that may be generated during the flipping process, ensuring that the center of gravity of the workpiece 200 remains dynamically stable within the support area. This prevents the workpiece 200 from slipping, shifting, or jamming during flipping, improving the safety and reliability of the flipping process. By placing the driven wheel 43 in one of the mounting slots 21 and coaxially driving the two support wheels 3 on the mounting slot 21, the transmission chain is simplified, the number of parts is reduced, and the absolute synchronization of the two support wheels 3 is ensured.

[0043] Specifically, such as Figure 2 As shown, the rotating component 53 is vertically mounted on the bracket 2, and the transmission component 41 is vertically mounted on the base plate 1. The rotating component 53 is provided with a first conical head 531, and the transmission component 41 is provided with a second conical head 411. The first conical head 531 and the second conical head 411 mesh with each other. This design reliably converts the rotational motion input from the drive mechanism 5 about the vertical direction into the rotational motion of the transmission component 41 about the horizontal direction, thus meeting the functional requirement of the support wheel 3 driving the workpiece 200 to rotate horizontally. At the same time, the bevel gear transmission allows power transmission between intersecting shafts, avoiding the need to use multi-stage parallel shaft gears or complex sprocket and chain mechanisms to achieve direction conversion. This makes the transmission structure from the rotating component 53 to the transmission component 41 compact, saving installation space at the bottom of the pallet device and facilitating the thin and lightweight design of the device.

[0044] Specifically, such as Figure 3As shown, the transmission mechanism 100 includes two spaced-apart transmission rails 101, and the drive mechanism 5 includes a fixed base 54 located between and connected to the two transmission rails 101. The lifting drive component 51 is mounted on the fixed base 54. The spaced arrangement of the two transmission rails 101 provides symmetrical and stable support for the base plate 1, ensuring the stability of the base plate 1 when moving in the first direction. At the same time, the gap between the two transmission rails 101 provides a reasonable space for the installation of the fixed base 54. On the other hand, the design of the fixed base 54 connecting the two transmission rails 101 not only enhances the structural strength of the transmission rails 101 themselves, but also provides a firm and precise installation reference for the lifting drive component 51, ensuring that the lifting drive component 51 is always in the centered position between the two transmission rails 101, and ensuring that when it drives the rotating drive component 52 to rise, the output end can be precisely aligned with the rotating groove 530 of the rotating component 53.

[0045] Specifically, such as Figure 3 As shown, the rotating groove 530 is a groove with a non-circular cross-section. The non-circular cross-section structure can form a circumferential limit, ensuring that there is no relative slippage between the output end of the rotating drive component 52 and the rotating groove 530 after they are inserted into the groove. This achieves efficient and lossless power transmission and ensures the stability of the power connection and the accuracy of the rotation angle when the workpiece 200 is flipped.

[0046] In this embodiment, the rotating groove 530 is a groove with a regular hexagonal cross-section.

[0047] In other embodiments, the cross-section of the rotating groove 530 may be polygonal, spline-shaped, or elliptical.

[0048] Specifically, such as Figure 4 As shown, the driving wheel 42 and the driven wheel 43 mesh with each other or are connected by a transmission belt 44. The gear meshing method has a compact structure and high transmission efficiency, ensuring that the support wheel 3 rotates in strict synchronization, thereby achieving precise and slip-free flipping of the workpiece 200. The transmission belt 44 can isolate the vibration and impact generated by the drive mechanism 5, making the flipping process smoother. At the same time, the transmission belt 44 can accommodate a certain center distance error, reducing the difficulty of manufacturing and assembly.

[0049] Specifically, the workpiece horizontal flipping device also includes a detector mounted on the bracket 2, configured to detect whether the workpiece 200 is placed on the bracket 2. This detection function can prevent the drive mechanism 5 from being erroneously activated when the workpiece 200 is not placed or is improperly placed. Otherwise, the idle rotation of the support wheel 3 would not only cause unnecessary wear, but more seriously, if the workpiece 200 falls due to instability during the flipping process, it may cause equipment damage or personal injury accidents. The intervention of the detector can provide proactive protection for equipment and personnel through pre-judgment.

[0050] Specifically, the lifting drive component 51 is a cylinder or an electric push rod, and the rotary drive component 52 is a rotary cylinder or a servo motor. The cylinder or electric push rod, as the lifting drive component 51, enables rapid response, stable force output, and precise range control of the lifting action, ensuring efficient and reliable drive connection. Using a rotary cylinder or servo motor as the rotary drive component 52 allows for rapid output of rotational power and high-precision control of the tilting angle, ensuring precise and stable adjustment of the workpiece's 200° posture.

[0051] The automated workflow of this embodiment is as follows: First, the external gripping mechanism transfers and positions the workpiece 200 onto the bracket 2; then, the detector confirms that the workpiece 200 is in place and wirelessly transmits the signal to the MES system; the MES system transmits a start command to activate the transmission mechanism 100, transporting the workpiece 200 to the preset workstation; upon reaching the preset workstation, the stopper limits the movement; then, the lifting drive 51 lifts the rotating drive 52 to dock with the rotating component 53; driving the workpiece 200 to complete a horizontal flip, preparing it for subsequent cleaning or rust removal operations. It should be noted that the MES system is a mature technology in this field, used to receive sensor data, issue control commands, and schedule production resources.

[0052] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
