Description

Technical Field

[0001] This utility model relates to the field of mechanical clamping device technology, and in particular to a highly stable dual servo cylinder synchronous clamping device. Background Technology

[0002] The electron accelerator beam conveyor rotates the electron accelerator goods 180° without blind spots during operation, so that the electron accelerator rays can more effectively cover the goods. This can quickly and effectively sterilize epidemic prevention or other daily necessities and extend their shelf life.

[0003] Currently, the synchronization devices equipped with electron accelerator beam conveying equipment are basically driven by a single cylinder. Single cylinders have the problems of large size and heavy operation. Moreover, the equipment needs to rotate 180° back and forth multiple times during operation. The installation method of single cylinder is difficult to position due to large inertia, resulting in complex control and high failure rate. Therefore, a highly stable dual servo cylinder synchronous clamping device is needed. Summary of the Invention

[0004] The purpose of this invention is to provide a highly stable dual-servo cylinder synchronous clamping device to solve the technical problems mentioned in the background section.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This utility model discloses a highly stable dual-servo cylinder synchronous clamping device, comprising a rotating frame. Two movable shafts are symmetrically fixedly arranged inside the rotating frame, with each end of the movable shaft fixedly connected to the inner walls of the upper and lower ends of the rotating frame. Two upper and lower clamping beams are symmetrically slidably arranged on the two movable shafts. Servo cylinders are fixedly arranged between the inner walls of the upper and lower ends of the rotating frame and the two upper and lower clamping beams. The ends of the two servo cylinders that are far apart are fixedly connected to the inner walls of the upper and lower ends of the rotating frame, while the ends of the two servo cylinders that are close together pass through one of the adjacent upper and lower clamping beams and are fixedly connected to the other upper and lower clamping beam that is far apart.

[0007] Furthermore, the rotating frame has two sets of sprockets symmetrically arranged at its upper and lower ends, and each set of sprockets is equipped with a chain that is compatible with it; the middle part of the two chains passes through the two upper and lower clamping beams respectively, and the two ends of each chain are fixedly connected to the two upper and lower clamping beams respectively.

[0008] Furthermore, a chain fixing frame is fixedly provided at the end of the two upper and lower clamping beams that are close to each other in a centrally symmetrical manner, and a chain fixing block is fixedly provided at the end of the two upper and lower clamping beams that are far apart in a centrally symmetrical manner; one end of each chain is connected to the chain fixing frame on one of the upper and lower clamping beams, and the other end is connected to the chain fixing block on the other upper and lower clamping beam.

[0009] Furthermore, two sleeve shafts are symmetrically fixedly arranged at the approaching ends of the two upper and lower clamping beams, and the two sleeve shafts on each upper and lower clamping beam are respectively slidably engaged with the two moving shafts.

[0010] Furthermore, connecting frames are fixedly provided at the ends of the two upper and lower clamping beams that are close to each other, and the output ends of each servo electric cylinder are fixedly connected to the corresponding connecting frames.

[0011] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0012] This invention uses the outputs of two servo electric cylinders to drive two connecting frames for linear movement. Each connecting frame is fixedly connected to two upper and lower clamping beams, allowing the servo electric cylinders to move the clamping beams together. Synchronous control of the two servo electric cylinders ensures the synchronized movement of the clamping beams. This invention features a simple structure and effectively reduces the overall weight of the rotating frame. Utilizing a dual-servo electric cylinder synchronous mechanism and closed-loop servo control, this invention achieves high-precision motion control and rapid response. It automatically adjusts the clamping force according to the weight and volume of the object being clamped, enabling rapid clamping and significantly reducing the rotation cycle of the rotating frame, thereby improving equipment efficiency and service life.

[0013] This invention features chain fixing blocks fixedly installed at opposite ends of two upper and lower clamping beams, and chain fixing frames fixedly installed at opposite ends of the two upper and lower clamping beams, thus ensuring that the chain length at both ends of the sprocket changes synchronously with the movement of the clamping beams when the upper and lower clamping beams move. This avoids the situation where the two servo cylinders cannot be synchronized due to issues such as the machining accuracy of the servo cylinders and the failure of the sealing rings.

[0014] In addition, this utility model achieves the effect of facilitating the movement of the upper and lower clamping beams by fixing the sleeve shafts on the side walls of the two upper and lower clamping beams. The sleeve shafts reduce the friction between the upper and lower clamping beams and the moving shaft. Attached Figure Description

[0019] like Figures 1-2 As shown, a highly stable dual-servo cylinder synchronous clamping device includes a rotating frame 1. Two vertically moving shafts 2 are symmetrically fixedly installed inside the rotating frame 1, with both ends of each shaft fixedly connected to the inner walls of the upper and lower ends of the rotating frame 1, respectively. Two upper and lower clamping beams 3 are symmetrically slidably installed on the two moving shafts 2. Specifically, two sleeve shafts 9 are symmetrically fixedly installed on the adjacent ends of each of the two upper and lower clamping beams 3, and the two sleeve shafts 9 on each upper and lower clamping beam 3 are slidably engaged with the two moving shafts 2.

[0020] Servo electric cylinders 6 are fixedly installed between the inner walls of the upper and lower ends of the rotating frame 1 and the two upper and lower clamping beams 3 respectively. The ends of the two servo electric cylinders 6 that are far apart are fixedly connected to the inner walls of the upper and lower ends of the rotating frame 1 respectively. The ends of the two servo electric cylinders 6 that are close to each other pass through one of the upper and lower clamping beams 3 that are close to each other and are fixedly connected to the other upper and lower clamping beam 3 that is far away from each other.

[0021] In this embodiment, a connecting frame 7 is fixedly installed at one end of the two upper and lower clamping beams 3 that are close to each other, and the output end of each servo electric cylinder 6 is fixedly connected to the corresponding connecting frame 7.

[0022] The rotating frame 1 has two sets of sprockets 5 symmetrically mounted at its upper and lower ends. Each of the two sprockets 5 in each set is equipped with a matching chain 4. The middle part of the two chains 4 passes through the two upper and lower clamping beams 3 respectively, and the two ends of each chain 4 are fixedly connected to the two upper and lower clamping beams 3 respectively.

[0023] Chain fixing frames 8 are fixedly installed at the ends of the two upper and lower clamping beams 3 that are close to each other in a centrally symmetrical manner, and chain fixing blocks 10 are fixedly installed at the ends of the two upper and lower clamping beams 3 that are far apart in a centrally symmetrical manner; one end of each chain 4 is connected to the chain fixing frame 8 on one of the upper and lower clamping beams 3, and the other end is connected to the chain fixing block 10 on the other upper and lower clamping beam 3.

[0024] The working principle of this utility model:

[0025] In use, the output ends of the two servo cylinders 6 drive the two connecting frames 7 to move linearly. The two connecting frames 7 are fixedly connected to the two upper and lower clamping beams 3 respectively. Therefore, the servo cylinders 6 can drive the upper and lower clamping beams 3 to move together. By synchronously controlling the two servo cylinders 6, the synchronous movement of the upper and lower clamping beams 3 is ensured. At the same time, the weight of the rotating part is greatly reduced, which helps to improve the service life of the equipment.

[0026] In use, chain fixing blocks 10, which are fixedly connected to the chain 4, are fixedly installed at the far ends of the two upper and lower clamping beams 3, and chain fixing frames 8, which are connected to the chain 4, are fixedly installed at the near ends of the two upper and lower clamping beams 3. Therefore, when the upper and lower clamping beams 3 move, the length of the chain 4 at both ends of the sprocket 5 changes synchronously with the movement of the upper and lower clamping beams 3. This avoids the situation where the two servo electric cylinders 6 cannot be synchronized due to problems such as the machining accuracy of the servo electric cylinder 6 and the failure of the sealing ring.

[0027] In use, by fixing the sleeve shaft 9 on the side wall of the two upper and lower clamping beams 3, the friction between the upper and lower clamping beams 3 and the moving shaft 2 is reduced by the sleeve shaft 9, thus facilitating the movement of the upper and lower clamping beams 3.

[0028] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
