Description

Technical Field

[0001] This application relates to a flipping clamping mechanism, belonging to the field of parts processing and manufacturing technology. Background Technology

[0002] In modern industrial manufacturing, especially in automated production lines and precision machining, workpiece flipping and clamping are two crucial operational steps. With the continuous improvement of industrial automation, the demand for efficient, precise, and reliable flipping and clamping mechanisms is increasing. Such mechanisms not only improve production efficiency but also ensure the stability and accuracy of workpieces during processing, thereby enhancing product quality.

[0003] Currently, various flipping and clamping mechanisms exist on the market, each with its own design features, but all generally suffer from some limitations. Traditional flipping mechanisms typically employ simple mechanical structures, such as manual flipping, which proves inadequate and inefficient when dealing with large or heavy workpieces. Furthermore, while some automated flipping mechanisms can achieve automatic flipping, they still fall short in terms of clamping stability and accuracy, making it difficult to meet the demands of high-precision machining. Summary of the Invention

[0004] The purpose of this application is to provide a flipping clamping mechanism to solve the aforementioned problems in the prior art. This mechanism, through a reasonable structural design, achieves stable clamping and precise flipping of objects.

[0005] The technical problem to be solved in this application is achieved by the following technical solution: A flipping clamping mechanism, comprising: A base, wherein two rotating shaft supports are spaced apart along the length direction, and a rotating shaft is rotatably connected to the rotating shaft supports; A clamping assembly is mounted on the rotating shaft; A flipping assembly, mounted on the base, is used to drive the rotating shaft to rotate.

[0006] Preferably, the flipping component includes: The first cylinder is mounted on the base; A rack is fixedly connected to the piston rod of the first cylinder; The gear is fixedly connected to the rotating shaft, and the gear meshes with the rack.

[0007] Preferably, a rack guide block is fixedly connected to the rotating shaft bracket, the rack guide block is provided with a guide groove, and the rack is slidably connected to the guide groove.

[0008] Preferably, the clamping assembly includes: The first clamping block is fixedly connected to the rotating shaft, and the first clamping block is provided with a first clamping surface; The second clamping block is rotatably connected to the first clamping block. The second clamping block is provided with a second clamping surface, and the second clamping surface and the first clamping surface together form a clamping space. The cylinder support is fixedly connected to the rotating shaft; The second cylinder has its cylinder body rotatably connected to the cylinder support, and its piston rod rotatably connected to the second clamping block. The second cylinder is used to drive the second clamping block to open or close the clamping space.

[0009] Preferably, a cylinder connector is fixedly connected to the piston rod, and the cylinder connector is rotatably connected to the second clamping block via an electroplated linear shaft.

[0010] Preferably, multiple clamping assemblies are installed at equal intervals along the length of the rotation axis.

[0011] Preferably, it also includes a buffer assembly mounted on the rotating shaft bracket to reduce mechanical impact during the flipping process and extend the equipment life.

[0012] Preferably, the buffer component includes: The buffer seat is fixedly connected to the rotating shaft bracket; Two buffers are mounted on the buffer seat; and the two buffers are symmetrically arranged about the rotation axis of the rotation shaft. The limiting block is fixedly connected to the rotating shaft.

[0013] Preferably, a connecting rod is fixedly connected between the two rotating shaft supports to enhance the stability of the two rotating shaft supports.

[0014] The beneficial effects of this application are: 1. Compact and rational structure: The overall mechanism is constructed from basic components such as the base, rotating shaft support, and rotating shaft to form a stable frame, with each component scientifically arranged. For example, the flipping component, clamping component, and buffer component are orderly installed on the base and related supports, making full use of space. This allows the mechanism to achieve multiple functions while maintaining a compact structure, reducing space occupation and facilitating installation and use in various industrial scenarios.

[0015] 2. Stable and Reliable Clamping: The clamping assembly adopts a design where the first and second clamping blocks together form the clamping space. The second cylinder drives the second clamping block to move, providing a stable and reliable clamping force. Multiple clamping components are installed at equal intervals along the rotation axis, allowing multiple objects to be clamped simultaneously according to actual needs. This not only improves work efficiency but also ensures that each object is stably clamped, reducing the risk of objects falling during the flipping process.

[0016] 3. Simple Flipping Operation: The flipping component is driven by a rack and pinion via a first cylinder, which in turn drives the rotating shaft through the meshing of the rack and pinion gears, thus achieving the flipping of the clamping component. This transmission method is simple and direct, and easy to operate. The flipping action can be easily completed by simply controlling the extension and retraction of the piston rod of the first cylinder, reducing the difficulty of operation and improving work efficiency.

[0017] 4. Effective Reduction of Mechanical Shock: The design of the buffer assembly is a major highlight of this application. When the rotating shaft rotates to a certain position, the limit block contacts the buffer, which absorbs and disperses mechanical energy, providing excellent buffering and significantly reducing the impact of mechanical shock on various components of the mechanism. This not only protects key transmission components such as the rotating shaft, gears, and racks, but also extends the service life of the entire mechanism, reducing equipment maintenance costs and replacement frequency.

[0018] 5. High flipping accuracy: The rack guide block ensures the stability of the rack during movement, making the meshing of the rack and gear more precise, reducing errors in the transmission process, thereby improving the rotation accuracy of the rotating shaft, and thus ensuring the accuracy of the flipping angle of the clamped object, meeting the needs of some production scenarios with high flipping accuracy requirements.

[0026] like Figures 1-4 As shown, a flipping clamping mechanism includes: a base 1, a clamping component, a flipping component, and a buffer component.

[0027] The base 1 has two rotating shaft supports 2 spaced apart along its length. A rotating shaft 3 is rotatably connected to each of the two rotating shaft supports 2 via bearings. A connecting rod 16 is fixedly connected between the two rotating shaft supports 2, greatly enhancing the stability of the rotating shaft supports 2, providing a more stable foundation for the rotation of the rotating shaft 3, reducing the overturning error caused by support swaying, and improving the overall operational stability of the mechanism. Specifically, both ends of the connecting rod 16 are provided with internal threaded holes, and both rotating shaft supports 2 are provided with threaded holes. The connecting rod 16 is fixed to the rotating shaft supports 2 by bolts.

[0028] The flipping assembly is mounted on the base 1 and is used to drive the rotating shaft 3 to rotate. Specifically, the flipping assembly includes: a first cylinder 5, mounted on the base 1; a rack 6, fixedly connected to the piston rod of the first cylinder 5; and a gear 7, fixedly connected to the rotating shaft 3 by a key, and meshing with the rack 6. A rack guide block 4 is fixedly connected to the rotating shaft bracket 2, and the rack guide block 4 is provided with a guide groove 401, to which the rack 6 is slidably connected. It should be noted that the first cylinder 5 is existing technology, such as a cylinder with model number CDQ2B32-75; the first cylinder 5 has two air ports, respectively connected to two air lines of an external air supply device. Typically, the external air supply device is an air compressor, which generates compressed air that, after filtration and pressure regulation, is used to control the flow of air into the two air ports of the first cylinder 5 via solenoid valves. The inlet of the solenoid valve is connected to the processed compressed air source, and the two outlets are connected to the two air ports of the first cylinder 5 via air pipes. When it is necessary to drive the clamping assembly to flip, a flip signal is sent to the control system via a button, causing the solenoid valve controlling the air intake path of the first cylinder 5 to activate. For example, to make the rotating shaft 3 rotate in the forward direction, the solenoid valve will connect the compressed air to the air path of the first cylinder 5 to push the piston rod out. After the compressed air enters the cylinder, it pushes the piston, and the piston drives the rack 6 to move. The rack 6 drives the rotating shaft 3 to rotate by meshing with the gear 7, thereby realizing the forward flipping of the clamping assembly. When it is necessary to flip in the reverse direction, the control system changes the state of the solenoid valve, allowing compressed air to enter the air path of the first cylinder 5 to push the piston rod back, thereby realizing the reverse flipping action.

[0029] The clamping assembly is mounted on the rotating shaft 3. Specifically, the clamping assembly includes: a first clamping block 8, which is fixedly connected to the rotating shaft 3 by bolts and has a first clamping surface; a second clamping block 9, which is rotatably connected to the first clamping block 8 via a shaft and has a second clamping surface, the second clamping surface and the first clamping surface together forming a clamping space; a cylinder support 10, which is fixedly connected to the rotating shaft 3 by bolts; and a second cylinder 11, whose cylinder body is rotatably connected to the cylinder support 10 and whose piston rod is rotatably connected to the second clamping block 9, the second cylinder 11 being used to drive the second clamping block 9 to open or close the clamping space. A cylinder connector 12 is fixedly connected to the piston rod, and the cylinder connector 12 is rotatably connected to the second clamping block 9 via an electroplated linear shaft. Further, multiple clamping assemblies are installed at equal intervals along the length of the rotating shaft 3. It should be noted that the second cylinder 11 is existing technology, such as model CDJ2D10-15. The second cylinder 11 has two air ports, and its connection method is similar to that of the first cylinder 5. Compressed air supplied by an external air supply device is connected to the two air ports of the second cylinder 11 after being controlled by a solenoid valve. By switching the on and off of the air path through the solenoid valve, the extension and retraction of the piston rod of the second cylinder 11 is realized, thereby controlling the opening and closing of the second clamping block 9. When it is necessary to clamp an object, a clamping command is sent to the control system, and the control system controls the corresponding solenoid valve to allow compressed air to enter the air path of the second cylinder 11 to drive the piston rod to extend. The piston rod pushes the second clamping block 9 to rotate through the cylinder connector 12 and the electroplated linear shaft, closing the clamping space and clamping the object. When it is necessary to release the object, a release command is sent to the control system, and the control system changes the on and off state of the solenoid valve to allow compressed air to enter the air path of the second cylinder 11 to drive the piston rod to retract. The piston rod retracts and drives the second clamping block 9 to rotate, opening the clamping space and releasing the object.

[0030] The buffer assembly is mounted on the rotating shaft support 2 to reduce mechanical impact during the rotation process and extend the equipment's lifespan. Specifically, the buffer assembly includes: a buffer seat 13, which is fixedly connected to the rotating shaft support 2; two buffers 14, mounted on the buffer seat 13, symmetrically arranged about the rotation axis 3; and a limiting block 15, which is fixedly connected to the rotating shaft 3 by a key. When the rotating shaft 3 rotates to a certain position, the limiting block 15 contacts the buffer 14, which absorbs and disperses mechanical energy, providing excellent buffering and significantly reducing the impact of mechanical impact on the various components of the mechanism. This not only protects key transmission components such as the rotating shaft 3, gear 7, and rack 6, but also extends the service life of the entire mechanism, reducing maintenance costs and replacement frequency. It should be noted that both buffers 14 are existing technologies, such as the self-contained hydraulic buffer 14 of model RBC1006.
