Description

Technical Field

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

[0002] In industrial production, logistics and transportation, and various automated equipment applications, precise clamping and stable delivery of objects is a critical requirement. Traditional clamping mechanisms often have many limitations when dealing with objects of different shapes and sizes.

[0003] Conventional clamping mechanisms typically employ fixed clamping methods, making it difficult to adaptively adjust to the actual shape and position of the object, resulting in unstable clamping centers. When clamping precision parts, positioning deviations may affect subsequent processing accuracy, increasing scrap rates and production costs. For objects with uneven or easily deformable surfaces, traditional clamping mechanisms cannot effectively adhere to the object's surface, easily leading to insecure clamping. When transporting fragile items such as glass products, unstable clamping frequently causes items to slip and become damaged, resulting in economic losses. When the size or shape of an object changes, traditional clamping mechanisms require manual readjustment of the clamping device, which is cumbersome and inefficient. In the trend of diversified product production, frequent manual adjustments severely restrict the improvement of production efficiency and cannot meet the needs of modern high-efficiency production.

[0004] Therefore, those skilled in the art have provided a hydraulic adaptive clamping mechanism to solve the problems mentioned in the background art. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides:

[0006] A hydraulic adaptive clamping mechanism includes: a housing;

[0007] A center clamping structure is fitted into the middle of the inner side of the housing;

[0008] Furthermore, both sides of the central clamping structure are provided with side clamping structures that are rotatably assembled inside the housing;

[0009] The two side clamping structures, together with the central clamping structure, can automatically position, clamp, and securely deliver the object to the center.

[0010] The clamping structure includes a triangular plate frame that is movably located inside the housing, and vertical sliding grooves are provided on both the front and rear sides of the triangular plate frame. A limiting ball that is rotatably installed on the inner wall of the housing is movably arranged inside the vertical sliding groove.

[0011] The triangular plate frame is movably restricted inside the limiting ball of the housing via a vertical sliding groove. The triangular plate frame can move stably vertically along the housing via the vertical sliding groove and the limiting ball.

[0012] Preferably, a hydraulic cylinder is assembled between the triangular plate frame and the machine housing, and the hydraulic cylinder is used to raise the triangular plate frame inside the machine housing.

[0013] The hydraulic cylinder is specifically an electro-hydraulic cylinder.

[0014] Preferably, the top of the triangular plate frame is equipped with a clamping roller, and the inner side of the clamping roller is provided with a number of buffer grooves in a ring at equal intervals.

[0015] The clamping roller is made of rubber. When the clamping roller clamps the item, the compressed buffer groove is concave, causing the clamping roller to deform according to the shape of the item, so that the item being clamped is stably positioned and clamped by the clamping roller.

[0016] Preferably, both ends of the triangular plate frame are provided with concave arc-shaped limiting grooves.

[0017] Preferably, the side clamp structure includes a side frame arc plate, and a reset rod that is rotatably mounted on the inner wall of the housing is fixedly installed in the middle of the side frame arc plate.

[0018] Preferably, a spiral spring is fitted between the reset rod and the housing.

[0019] The spiral spring is used to reset the rotation angle of the reset rod.

[0020] Preferably, the top of the side frame arc plate is equipped with a clamping roller, and the bottom of the side frame arc plate is fixedly provided with a sliding rod, and a sliding pulley located on the side of the triangular plate frame is rotatably installed on the outside of the sliding rod.

[0021] When the triangular plate frame is pushed up by the hydraulic cylinder, the triangular plate frame will push the bottom of the side frame arc plate outward through the pulley, so that the clamping roller at the top of the side frame arc plate will clamp the item to be clamped inward.

[0022] An assembly plate is fixed to the bottom of the housing as a whole;

[0023] The controller is mounted on the side of the housing.

[0024] The technical effects and advantages of this utility model are as follows:

[0025] This invention utilizes the side clamping structures on both sides and the central clamping structure to automatically position and clamp objects, ensuring a stable clamping center. The triangular plate frame of the central clamping structure, through the cooperation of a vertical sliding groove and a limiting ball, can move vertically stably and can be precisely adjusted in position under the push of a hydraulic cylinder. When the triangular plate frame rises, the side frame arc plate is pushed by a rotating pulley, causing the top clamping roller to clamp the object inward, ensuring that the object's position is stable and not easily deviated during the clamping process.

[0026] This utility model features a clamping roller made of rubber with multiple buffer grooves on its inner side. When clamping an item, the buffer grooves deform inward according to the shape of the item, closely fitting the surface of the item. Whether the item is regular or irregular in shape, it can achieve stable clamping and avoid damage to the item due to improper clamping. It is suitable for clamping and conveying various types of items. Attached Figure Description

[0038] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The examples of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0039] For examples, please refer to Figures 1-5 This embodiment provides a hydraulic adaptive clamping mechanism, including: a housing 1; a central clamping structure 4 is assembled in the middle of the inner side of the housing 1; and side clamping structures 2 are rotatably assembled on both sides of the central clamping structure 4 on the inner side of the housing 1; the two side clamping structures 2, together with the central clamping structure 4, can automatically position and clamp the object to be clamped, stabilize and clamp it; the central clamping structure 4 includes a triangular plate frame 401 movably located inside the housing 1, and vertical sliding grooves 402 are provided on both the front and rear sides of the triangular plate frame 401; a limiting ball 7 is rotatably mounted on the inner wall of the housing 1 and movably arranged inside the vertical sliding groove 402; the triangular plate frame 401 is movably limited inside the limiting ball 7 of the housing 1 by the vertical sliding groove 402, and the triangular plate frame 401 can move stably vertically along the housing 1 by the vertical sliding groove 402 and the limiting ball 7;

[0040] A hydraulic cylinder 404 is assembled between the triangular plate frame 401 and the housing 1. The hydraulic cylinder 404 is used to raise the triangular plate frame 401 inside the housing 1. The hydraulic cylinder 404 is specifically an electric hydraulic cylinder. A clamping roller 3 is assembled at the top of the triangular plate frame 401. The inner side of the clamping roller 3 is provided with a plurality of buffer grooves 301 in an annular shape. The clamping roller 3 is made of rubber. When the clamping roller 3 clamps an object, the buffer grooves 301 are compressed and concave, causing the clamping roller 3 to deform according to the shape of the object being clamped, so that the object being clamped is stably positioned and clamped by the clamping roller 3. Both ends of the triangular plate frame 401 are provided with concave arc-shaped limiting grooves 403.

[0041] The side clamping structure 2 includes a side frame arc plate 201, and a reset rod 202 rotatably mounted on the inner wall of the housing 1 is fixedly installed in the middle of the side frame arc plate 201; a spiral spring 203 is assembled between the reset rod 202 and the housing 1; the spiral spring 203 is used to reset the rotation angle of the reset rod 202; a clamping roller 3 is assembled at the top of the side frame arc plate 201, and a rotating slide rod 204 is fixedly installed at the bottom of the side frame arc plate 201. A rotating pulley 205 is rotatably mounted on the outer side of the triangular frame 401 and slides on the side of the triangular frame 401. When the triangular frame 401 is pushed up by the hydraulic cylinder 404, the triangular frame 401 will push the bottom of the side frame arc plate 201 outward through the rotating pulley 205, so that the clamping roller 3 at the top of the side frame arc plate 201 will clamp the item to be clamped inward. An assembly plate 5 is fixed to the bottom of the housing 1. A controller 6 is installed on the side of the housing 1.

[0042] According to the above embodiments, the working principle of this invention is as follows:

[0043] When the equipment is started, the controller 6 sends a command to the hydraulic cylinder 404, and the hydraulic cylinder 404, which is the body of the electric hydraulic cylinder, starts to work. The hydraulic cylinder 404 pushes the triangular plate frame 401 to rise inside the housing 1. Since there are limiting balls 7 in the vertical sliding grooves 402 on the front and rear sides of the triangular plate frame 401, the limiting balls 7 are rotatably installed on the inner wall of the housing 1, and the triangular plate frame 401 can only make stable vertical movement along the housing 1.

[0044] Side clamping structure 2 operation and object clamping: During the upward movement of the triangular plate frame 401, the rotating pulleys 205 at both ends of the triangular plate frame 401 contact the rotating sliding rod 204 at the bottom of the side frame arc plate 201 and push the side frame arc plate 201; the side frame arc plate 201 rotates around the reset rod 202 as the axis, causing the clamping roller 3 at the top of the side frame arc plate 201 to move inward, and together with the clamping roller 3 at the top of the middle clamping structure 4, clamps the object; at this time, the rubber clamping roller 3 is squeezed, and the inner buffer groove 301 is concave, deforming according to the shape of the object, and closely adhering to the surface of the object to achieve stable clamping;

[0045] Clamping and Reset: After clamping is completed, the equipment drives the entire clamping mechanism to move, realizing the clamping of the object; when the clamping task is completed, the hydraulic cylinder 404 stops working and retracts, and the triangular plate frame 401 descends; at this time, the spiral spring 203 in the side clamping structure 2 plays a role. It stores the elastic potential energy generated when the side frame arc plate 201 rotates, and releases the energy to make the reset rod 202 drive the side frame arc plate 201 to rotate in the opposite direction and return to the initial position, waiting for the next clamping task.
