Description

Technical Field

[0001] This utility model applies to the technical field of profile workpiece flipping mechanisms, and in particular, a flipping mechanism. Background Technology

[0002] In the field of industrial automation, workpiece flipping is a key link in the production process, especially in the automated production of sheet metal. Automatic bending of sheet metal requires flipping the entire sheet metal before bending. However, traditional flipping mechanisms have the following drawbacks: 1. Some mechanisms use complex gear transmissions or direct motor drives, resulting in structural redundancy, high costs, and difficult maintenance; 2. Some mechanisms lack precise guidance during the flipping process, which can easily lead to workpiece deviation and uneven movement, affecting processing accuracy and stability.

[0003] To address the aforementioned pain points, this utility model provides a flipping mechanism that features a compact structure, high transmission efficiency, and precise flipping. Through modular design, it can reduce manufacturing costs and maintenance difficulty, and is suitable for various profile workpiece flipping operation scenarios. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a flipping mechanism, which has the characteristics of compact structure, high transmission efficiency and precise flipping. Through modular design, it can reduce manufacturing costs and maintenance difficulty, and is suitable for various profile workpiece flipping operation scenarios.

[0005] The technical solution adopted by this utility model to solve its technical problem is: This utility model provides a flipping mechanism, which includes a base, a drive assembly, a linkage transmission assembly, an execution assembly, and a guide assembly. The drive assembly is fixed on the base, the execution assembly is slidably fitted on the guide assembly, and the linkage transmission assembly is hinged to the movable ends of the guide assembly, the execution assembly, and the drive assembly respectively. The drive assembly drives the linkage transmission assembly to move, thereby driving the execution assembly to achieve the flipping action of the workpiece.

[0006] As described above, in a flipping mechanism, the base includes an aluminum profile and a support block. The aluminum profile is used to construct the frame structure of the base, and the support block is installed at any position on the mounting track of the aluminum profile by threaded fasteners.

[0007] As described above, in a flipping mechanism, the drive assembly includes a cylinder element, the cylinder body of which is disposed on the base, and the movable end of the drive assembly is provided with a connecting rod joint that is hinged to the connecting rod transmission assembly.

[0008] As described above, in a flipping mechanism, the actuating component includes an L-shaped clamping frame and a sliding seat. The corner of the clamping frame is hinged to the sliding seat. The sliding seat is used to drive the clamping frame to slide back and forth during the flipping process. The long section of the clamping frame is used to support the workpiece to be flipped and is hinged to the linkage transmission assembly. The short section of the clamping frame is used to limit the horizontal movement of the flipped workpiece.

[0009] As described above, in a flipping mechanism, the guide assembly includes a fixed base and a guide rod, the guide rod is installed in the fixed base, and the actuation assembly is slidably sleeved on the guide rod via a linear bearing.

[0010] In the flipping mechanism described above, the inner walls of the long and short sections of the clamping frame are provided with wear-resistant pads.

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figure 1 and Figure 4 As shown, in this embodiment, the present invention includes a base 1, a drive assembly 2, a linkage transmission assembly 3, an execution assembly 4, and a guide assembly 5. The drive assembly 2 is fixed on the base 1, the execution assembly 4 is slidably fitted on the guide assembly 5, and the linkage transmission assembly 3 is hinged to the guide assembly 5, the execution assembly 4, and the movable end of the drive assembly 2. The drive assembly 2 drives the linkage transmission assembly 3 to move, thereby driving the execution assembly 4 to achieve the flipping action of the workpiece. Therefore, the base 1 provides rigid support and installation reference for the entire device, the drive component 2 provides driving force for the flipping action, and the drive component 2 is a servo motor, cylinder or hydraulic cylinder. The linkage transmission component 3 converts the motion of the drive component into the flipping trajectory required by the execution component 4. The hinge structure enables smooth flipping action and avoids transmission jamming. The execution component 4 is a clamping and flipping execution component, which flips the workpiece by 90°. The guide component 5 precisely limits the motion trajectory of the execution component 4 and, together with the push of the drive component 2, effectively avoids workpiece offset, shaking or angular deviation during the flipping process, improving the consistency of workpiece flipping. Each component adopts a modular assembly method, and the parameters of the relevant components can be adjusted according to the size or weight of different workpieces to adapt to the flipping requirements of various workpieces, and also reduces the difficulty of device maintenance and repair.

[0017] Furthermore, in this embodiment, the base 1 includes an aluminum profile 10 and a support block 11. The aluminum profile 10 is used to construct the frame structure of the base 1, and the support block 11 is installed at any position on the mounting rail of the aluminum profile 10 using threaded fasteners. Thus, the aluminum profile 10 serves as the base frame, providing a lightweight and high-strength support platform, and it has several mounting rails to support the installation of the support block 11 at any position. The support block 11 serves to fix the drive assembly 2, improving the convenience of assembly and maintenance.

[0018] Furthermore, in this embodiment, the drive assembly 2 includes a cylinder element, the cylinder body of which is disposed on the base 1, and the movable end of the drive assembly 2 is provided with a connecting rod joint 20 that is hinged to the connecting rod transmission assembly 3. Thus, the cylinder element is a common drive assembly, possessing advantages such as fast response speed and stable power output. Compared with electric drive assemblies (such as servo motors), the cylinder element has a simple structure, low manufacturing cost, and no complex circuits or precision gear structures. It also has low maintenance difficulty and cost, making it suitable for high-frequency, low-complexity flipping operations. The connecting rod joint 20 serves as the connector between the cylinder piston rod and the connecting rod transmission assembly 3, achieving a hinged connection. Furthermore, the connecting rod joint 20 allows for angular displacement between the two during movement, avoiding stress concentration or jamming caused by rigid connections.

[0019] Furthermore, in this embodiment, the execution component 4 includes an L-shaped clamping frame 40 and a sliding seat 41. The corner of the clamping frame 40 is hinged to the sliding seat 41. The sliding seat 41 is used to drive the clamping frame 40 to slide back and forth during the flipping process. The long section of the clamping frame 40 is used to support the workpiece to be flipped and is hinged to the linkage transmission component 3. The short section of the clamping frame 40 is used to limit the horizontal movement of the flipped workpiece. Therefore, the L-shaped clamping frame 40 can clamp the regular workpiece with some thickness. The longer section of the clamping frame 40 directly contacts and supports the workpiece to be flipped, and its central force-bearing point is hinged to the connecting rod transmission assembly 3, realizing the flipping action of the clamping frame, thereby flipping the workpiece. The shorter section restricts the horizontal movement of the workpiece during the flipping process, forming an L-shaped angle with the longer section, thus constituting a "cugging" clamping structure, enhancing the stability of the workpiece during flipping and preventing it from falling off. The sliding seat 41 is hinged to the clamping frame, forming a composite motion of "sliding + flipping," which further enables the smooth flipping of the workpiece. This design saves more space than pure rotation or pure sliding, and can achieve complex movements in a limited space, adapting to the trend of equipment miniaturization and modularization.

[0020] Furthermore, in this embodiment, the guiding component 5 includes a fixed base 50 and a guide rod 51. The guide rod 51 is installed within the fixed base 50, and the actuating component is slidably sleeved onto the guide rod 51 via a linear bearing. Thus, the fixed base 50 serves as a mounting base for the guide rod 51, and the guide rod 51 provides a sliding path for the sliding seat 41, ensuring that the sliding seat 41 slides along a predetermined direction. This achieves high-precision, low-friction, and high-reliability linear motion guidance for the actuating component 4.

[0021] Furthermore, in this embodiment, wear-resistant pads are provided on the inner walls of the long and short sections of the clamping frame. Thus, the clamping frame provides support and fixation for the wear-resistant pads. Since the clamping frame is in direct contact with the workpiece surface, friction and wear will occur. The wear-resistant pads, by sacrificing their own material, withstand this wear, preventing the clamping frame body from experiencing a decrease in dimensional accuracy or even cracking due to wear, thereby extending the service life of the clamping frame. By changing the wear-resistant pads to different hardness, thickness, or materials, it is possible to adapt to workpieces of different sizes, shapes, and surface characteristics, further improving the versatility of this device.

[0022] The working principle of this utility model is as follows: First, the operator starts the cylinder element. The piston drives the connecting rod joint 20 to move linearly. The connecting rod transmission assembly 3 transmits power and converts it into a flipping motion. The actuator 4 slides along the guide assembly 5, causing the workpiece to flip. The guide assembly 5 restricts the trajectory of the actuator 4 to prevent deviation. Adjusting the cylinder pressure controls the flipping speed to ensure workpiece stability. When the workpiece flips to a preset angle, the cylinder piston stops, the connecting rod transmission assembly 3 locks, and the actuator 4 is positioned under the limit of the guide assembly 5.

[0023] It should be understood that the terms "first," "second," etc., are used in this utility model to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this utility model, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information. In addition, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] The above embodiments do not limit the scope of protection of this utility model. All equivalent modifications and variations made by those skilled in the art without departing from the overall concept of this utility model shall still fall within the scope of this utility model.
