Description

Technical Field

[0001] This utility model relates to the field of linkage clamping technology, specifically a linkage clamping mechanism. Background Technology

[0002] A clamping mechanism is a mechanical device used to clamp and secure tools or workpieces. It has wide applications in various fields such as industrial production, food handling, and minimally invasive surgery. The clamping mechanism positions and secures tools or workpieces through its mechanical structure. Its power source can be pneumatic, electric, hydraulic, or a combination of these, converting the motion of the drive device into the displacement necessary for the working elements of the clamp.

[0003] The prior art (Chinese patent with publication number CN105081999B and publication date of 2018-09-07) discloses a clamping mechanism, which includes: a first clamping arm having a first jaw, a second clamping arm having a second jaw and pivotally connected to the first clamping arm, and a screw assembly connected between the first clamping arm and the second clamping arm for driving the first jaw and the second jaw to move relative to each other. The screw assembly also includes a torque input part that can accept the torque of a rotary power unit. The clamping mechanism can reduce or expand the clamping area under the drive of the rotary power unit, avoiding the disadvantages of manual operation being time-consuming and easy to fatigue, and can quickly clamp or release workpieces.

[0004] While existing technologies can quickly clamp or release workpieces, the screw is prone to wear and jamming during long-term use, affecting its stability and reliability. It can only effectively clamp specific types of objects and cannot meet diverse production needs.

[0005] Therefore, we propose a linkage clamping mechanism to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a linkage clamping mechanism to solve the problems mentioned in the background art, such as the screw being prone to wear and jamming during long-term use, affecting its working stability and reliability, and being able to effectively clamp only specific types of objects, thus failing to meet diverse production needs.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a linkage clamping mechanism, including a fixed frame, a limiting plate fixedly connected to the lower part of the fixed frame, a slider slidably connected to the outer side of the limiting plate, and a clamping block for clamping an object fixedly connected to the lower end of the slider. An adjustment mechanism is provided between the side of the slider and the limiting plate, and the adjustment mechanism adjusts the distance between the two sets of sliders by rotating the angle of the rotating plate it contains.

[0008] Furthermore, the limiting plate is arranged in an inverted "T" shape when viewed from the side, and the inner side of the clamping block is arranged in an inclined triangular shape. The clamping block with the inwardly inclined structure can stably clamp the columnar object.

[0009] Furthermore, a cylinder is fixedly connected to the upper surface of the fixing frame, and a connecting plate is fixedly connected to the output end of the cylinder. An upper abutment rod is fixedly connected to the connecting plate, and two sets of upper abutment rods are symmetrically distributed about the center point of the connecting plate.

[0010] Furthermore, the adjustment mechanism includes a fixed shaft, which is fixedly connected to the outside of the limiting plate, and a rotating plate is rotatably connected to the outside of the fixed shaft. Two sets of rotating plates are symmetrically arranged about the center point of the fixed frame, and two sets of rotating plates are arranged on each of the front and rear sides of the limiting plate.

[0011] Furthermore, the upper abutment rod is arranged in an inclined "L" shape, and an upper sliding groove is provided on the upper side of the rotating plate. The upper abutment rod is slidably disposed on the upper sliding groove, and the rotating plate rotates along the fixed axis through the abutment action of the upper abutment rod.

[0012] Furthermore, a downward groove is provided on the lower side of the rotating plate, and a lower abutment rod is slidably arranged inside the downward groove, with the inner side of the lower abutment rod fixedly connected to the outer side of the slider.

[0013] Furthermore, the slider slides along the limiting plate through the contact action between the rotating plate and the lower abutment rod. When the limiting plate moves downward, the two sets of sliders move in opposite directions.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. The angle of rotation of the rotating plate is used to adjust the distance between the two sets of sliders, thereby achieving stable clamping of the object. At the same time, the rotating plate is equipped with upper and lower sliding grooves on both sides. During the rotation of the rotating plate, the upper and lower abutting rods will generate a resisting force with the upper and lower sliding grooves, thereby converting the arc-shaped motion trajectory of the rotating plate into the linear motion trajectory of the slider, making the clamping action more stable and precise.

[0015] 2. By adjusting the stroke of the cylinder, the moving distance of the limit plate can be controlled, thereby precisely controlling the rotation angle of the rotating plate and realizing flexible adjustment of the distance between the two sets of sliders to meet the clamping requirements of objects of different sizes.

[0016] 3. The limiting plate provides a stable guide for the sliding of the slider, ensuring the smoothness and stability of the slider's movement. It ensures that when the two sets of sliders slide, they can drive the two sets of clamping blocks to move stably, thereby preventing positional displacement during the clamping operation. At the same time, the inner side of the clamping block has an inclined triangular structure, which can stably clamp cylindrical objects, improving the reliability of clamping.

[0017] 4. The connection between its various components is relatively simple, allowing operators to easily disassemble and replace parts in case of malfunction or maintenance, reducing maintenance costs and difficulty. It also boasts higher transmission efficiency and lower energy loss, effectively lowering operating costs. Furthermore, the components are easy to process and manufacture, and replacement is convenient in case of damage or wear, resulting in high maintainability. This significantly reduces equipment repair time and costs, improving work efficiency. Attached Figure Description

[0020] 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.

[0021] Example 1: As Figures 1-3The technical solution shown is provided by the present invention as follows: A linkage clamping mechanism is disclosed, which discloses a clamping block 6 with an inwardly inclined structure. The clamping block 6 can stably clamp a columnar object: a limiting plate 4 is fixedly connected to the lower part of the fixing frame 1, and a slider 5 is slidably connected to the outer side of the limiting plate 4. The lower end of the slider 5 is fixedly connected to a clamping block 6 for clamping the object. The limiting plate 4 is arranged in an inverted "T" shape when viewed from the side, and the inner side of the clamping block 6 is arranged in an inclined triangular shape. The columnar object can be stably clamped by the clamping block 6 with the inwardly inclined structure.

[0022] By adjusting the stroke of cylinder 2, the moving distance of limit plate 4 can be precisely controlled. The moving distance of limit plate 4 directly determines the rotation angle of rotating plate 7, thereby realizing flexible adjustment of the distance between the two sets of sliders 5 to meet the clamping requirements of objects of different sizes. Limit plate 4 not only provides a stable guide for the sliding of slider 5, ensuring the smoothness and stability of slider 5 sliding, but also enables the two sets of sliders 5 to stably drive the two sets of clamping blocks 6 to move during the sliding process, effectively avoiding the displacement of the object position during the clamping process. In addition, the inner side of clamping block 6 adopts an inclined triangular structure design. This structure can achieve stable clamping of columnar objects, further improving the reliability of clamping operation.

[0023] Example 2: Figures 4-6 The technical solution shown is provided by this utility model as follows: A linkage clamping mechanism is disclosed, which enables stable clamping of an object. An adjustment mechanism is provided between the side of the slider 5 and the limiting plate 4. The adjustment mechanism adjusts the distance between the two sets of sliders 5 by rotating the rotating plate 7 it contains. A cylinder 2 is fixedly connected to the upper surface of the fixed frame 1, and a connecting plate 3 is fixedly connected to the output end of the cylinder 2. An upper abutment rod 11 is fixedly connected to the connecting plate 3. Two sets of upper abutment rods 11 are symmetrically distributed about the center point of the connecting plate 3. The adjustment mechanism includes a fixed shaft 10, which is fixedly connected to the outside of the limiting plate 4, and the outside of the fixed shaft 10 is rotatably connected to... There is a rotating plate 7, and two sets of rotating plates 7 are symmetrically arranged about the center point of the fixed frame 1. Two sets of rotating plates 7 are arranged on the front and rear sides of the limiting plate 4. The upper abutment rod 11 is arranged in an inclined "L" shape. An upper sliding groove 8 is opened on the upper side of the rotating plate 7. The upper abutment rod 11 is slidably arranged on the upper sliding groove 8. The rotating plate 7 rotates along the fixed shaft 10 through the abutment action of the upper abutment rod 11. A lower sliding groove 9 is opened on the lower side of the rotating plate 7. A lower abutment rod 12 is slidably arranged inside the lower sliding groove 9. The inner side of the lower abutment rod 12 is fixedly connected to the outer side of the slider 5. The slider 5 slides along the limiting plate 4 through the abutment action of the rotating plate 7 and the lower abutment rod 12. When the limiting plate 4 moves down, the two sets of sliders 5 move in opposite directions.

[0024] An upper sliding groove 8 is provided, which provides space for the movement of the upper abutment rod 11. When it is necessary to clamp the object, the cylinder 2 is activated. The output end of the cylinder 2 drives the limiting plate 4 to move upward. At this time, the upper abutment rod 11 slides in the upper sliding groove 8 on the rotating plate 7. Since the upper abutment rod 11 has an inclined "L" shape, it will abut against the rotating plate 7 during the sliding process, causing the rotating plate 7 to rotate along the fixed axis 10. When the rotating plate 7 rotates, the lower sliding groove 9 will simultaneously apply a resisting force to the lower abutment rod 12. Since the lower abutment rod 12 is fixedly connected to the slider 5, after the lower abutment rod 12 is subjected to force, it drives the slider 5 to slide along the limiting plate 4. At this time, the two sets of sliders 5 move towards each other, driving the clamping block 6 to move closer, thereby realizing the clamping operation of the object.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
