Description

Technical Field

[0001] This utility model relates to the field of toothless hydraulic sleeve clamp technology, specifically a clamping mechanism and a toothless hydraulic sleeve clamp. Background Technology

[0002] Hydraulic pipe wrenches are essential tools widely used in industrial pipeline installation, maintenance, and testing. Traditional hydraulic pipe wrenches typically use a direct clamping method to fix the pipe body. This method often leaves obvious clamp marks on the pipe surface, which not only affects the aesthetics but may also adversely affect the strength and sealing performance of the pipe body.

[0003] However, in existing technologies, hydraulic sleeve wrenches typically require changing the clamping components of different specifications when clamping pipes of different diameters. This not only increases operational complexity but also reduces work efficiency. Furthermore, they lack sufficient clamping force and stability during pipe clamping. While some products can adapt to pipes of different diameters, they still face difficulties when clamping pipes with special shapes. Therefore, this invention proposes a clamping mechanism and a toothless hydraulic sleeve wrench. Utility Model Content

[0004] The purpose of this utility model is to provide a clamping mechanism and a toothless hydraulic sleeve clamp to solve the problem of gripping and holding the surface of packaging boxes by existing drop testing machines mentioned in the background art, and to realize the gripping and holding drop testing of packaging boxes of different sizes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clamping mechanism and a toothless hydraulic sleeve clamp, comprising:

[0006] A mounting frame is fixedly connected to a hydraulic cylinder on its surface. The output shaft of the hydraulic cylinder is fixedly connected to a gear plate. The teeth of the gear plate mesh with the teeth of a gear. The inside of the gear is rotatably connected to the surface of a fixed shaft. The end of the fixed shaft is fixedly connected to the inside of the mounting frame. A rotating block is provided on the surface of the gear, and a clamping clamp is provided at the end of the rotating block.

[0007] Preferably, the outer surface of the gear is fixedly connected to the surface of the mounting port, the mounting port is opened inside the rotating block, and the rotating block is configured in two sets, and the two sets of rotating blocks are symmetrically arranged along the central axis of the mounting frame.

[0008] Preferably, the end of the rotating block has a notch, the surface of the notch is fixedly connected to the end of the support shaft, the surface of the support shaft is rotatably connected to the interior of the rotating block, the end of the rotating block is fixedly connected to the end of the clamping pliers, and the surface of the clamping pliers has an arc-shaped notch.

[0009] Preferably, the end face of the rotating block is provided with a toothed groove, the teeth of the toothed groove mesh with the threaded surface of the screw, the inside of the screw is fixedly connected to the surface of the rotating shaft, and the surface of the rotating shaft is rotatably connected to the inside of the rotating block.

[0010] Preferably, the end face of the rotating block is arc-shaped, and the end face of the rotating block is provided with multiple sets of tooth grooves, which are evenly distributed along the arc surface of the rotating block.

[0011] Preferably, the gears are configured in two sets, and the two sets of gears are symmetrically arranged along the central axis of the gear plate.

[0012] A toothless hydraulic sleeve wrench includes a clamping mechanism.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: by activating the hydraulic cylinder, the gear plate transmission meshing gear rotates within the mounting frame, thereby allowing the rotating block to adjust its angle through the rotation of the gear within the mounting frame. By setting a clamping clamp at the end of the rotating block, the clamping clamp can clamp the surface of the pipe body by adjusting the angle of the rotating block. By fixing the end of the rotating block to the end of the clamping clamp, the clamping angle of the pipe body can be changed when the angle of the rotating block is adjusted. When the knob is turned, the rotating shaft drives the screw to rotate within the recess of the rotating block, thus the screw drives the rotating block, allowing the clamping clamp to adjust its angle.

[0021] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1, please refer to Figures 1-6 This utility model provides a technical solution: a clamping mechanism and a toothless hydraulic sleeve clamp, comprising:

[0023] Mounting frame 1, with hydraulic cylinder 2 fixedly connected to the surface of mounting frame 1, output shaft of hydraulic cylinder 2 fixedly connected to gear plate 3, teeth of gear plate 3 meshing with teeth of gear 5, internal rotational connection of gear 5 to surface of fixed shaft 4, end of fixed shaft 4 fixedly connected to internal of mounting frame 1, rotating block 6 provided on surface of gear 5, and clamping clamp 8 provided at end of rotating block 6.

[0024] By activating the hydraulic cylinder 2, the gear plate 3 drives the meshing gear 5 to rotate within the mounting frame 1. The rotation of the gear 5 within the mounting frame 1 allows the rotating block 6 to adjust its angle. By setting a clamping clamp 8 at the end of the rotating block 6, the clamping clamp 8 can clamp the surface of the pipe body by adjusting the angle of the rotating block 6.

[0025] Example 2, see attached document Figures 1 to 6 Based on Embodiment 1, in order to change the clamping angle of the clamping pliers 8 on the tube body, the end of the rotating block 6 is provided with a notch, the surface of the notch is fixedly connected to the end of the support shaft 10, the surface of the support shaft 10 is rotatably connected to the interior of the rotating block 9, the end of the rotating block 9 is fixedly connected to the end of the clamping pliers 8, and the surface of the clamping pliers 8 is provided with an arc-shaped notch.

[0026] By fixing the end of the support shaft 10 to the notch surface of the rotating block 6, and then rotating the surface of the support shaft 10 to the inside of the rotating block 9, the rotating block 9 can rotate along the surface of the support shaft 10. By fixing the end of the rotating block 9 to the end of the clamping pliers 8, the clamping angle of the clamping pliers 8 on the tube can be changed when the angle of the rotating block 6 is adjusted.

[0027] Example 3, refer to Appendix Figures 1 to 6 Based on Embodiment 2, in order for the screw 12 to drive the rotating block 9 so that the clamping clamp 8 can adjust its angle, the end face of the rotating block 9 is provided with a toothed groove 13. The teeth of the toothed groove 13 mesh with the threaded surface of the screw 12. The interior of the screw 12 is fixedly connected to the surface of the rotating shaft 11, and the surface of the rotating shaft 11 is rotatably connected to the interior of the rotating block 6.

[0028] By engaging the teeth of the toothed groove 13 with the threaded surface of the screw 12, the internal surface of the screw 12 is fixedly connected to the surface of the rotating shaft 11. When the knob is turned, the rotating shaft 11 drives the screw 12 to rotate in the recess of the rotating block 6. Therefore, the screw 12 drives the rotating block 9 so that the clamping clamp 8 can be adjusted in angle.

[0029] In actual use, the hydraulic cylinder 2 is activated to cause the gear plate 3 to drive the meshing gear 5 to rotate within the mounting frame 1. The rotation of the gear 5 within the mounting frame 1 allows the rotating block 6 to adjust its angle. A clamping clamp 8 is installed at the end of the rotating block 6, so the clamping clamp 8 can clamp the surface of the pipe by adjusting the angle of the rotating block 6. The end of the support shaft 10 is fixedly connected to the notch surface of the rotating block 6, and then the surface of the support shaft 10 is rotatably connected to the rotating block 9, so the rotating block 9 can rotate along the surface of the support shaft 10. The end of the rotating block 9 is fixedly connected to the end of the clamping clamp 8, so the clamping angle of the clamping clamp 8 on the pipe can be changed when the angle of the rotating block 6 is adjusted. The screw surface of the screw 12 meshes with the teeth of the tooth groove 13, and the interior of the screw 12 is fixedly connected to the surface of the rotating shaft 11. When the knob is turned, the rotating shaft 11 drives the screw 12 to rotate within the notch of the rotating block 6, so the screw 12 drives the rotating block 9, allowing the clamping clamp 8 to adjust its angle.
