[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] Please see Figure 1-4 The present invention provides a technical solution: a wedge-shaped clamping mechanism, including a base plate 1 and a clamping mechanism 2, wherein the clamping mechanism 2 is provided on one side of the surface of the base plate 1;

[0022] The clamping mechanism 2 includes a fixed frame 201, a hydraulic cylinder 202, a first limiting groove 203, a groove 204, a second limiting groove 205, a fixed base 206, a first limiting block 207, a positioning rod 208, a spring 209, a second limiting block 210, a bolt 211, a slider 212, a sliding sleeve 213, a clamping block 214, and a connecting plate 215. The fixed frame 201 is mounted on one side of the surface of the base plate 1, and the hydraulic cylinder 202 is mounted on another side of the base plate 1. The side wall of the fixed frame 201 has a first limiting groove 203 and a groove 204. 04. A second limiting groove 205 is provided at the bottom of the fixing frame 201. A fixing seat 206 is connected to one side of the surface of the oil cylinder 202. A first limiting block 207 is fitted inside the first limiting groove 203. A positioning rod 208 is connected to one side of the groove 204. A spring 209 is connected to one side of the groove 204. A second limiting block 210 is fitted inside the second limiting groove 205. A bolt 211 is fitted inside the fixing seat 206. A slider 212 is connected to one side of the surface of the first limiting block 207. A sliding sleeve 213 is fitted to the surface of the positioning rod 208. One side of the second limiting block 210 is connected to a clamping block 214, and one end of the slider 212 is connected to a connecting plate 215. Through the arrangement of the fixing frame 201, oil cylinder 202, first limiting groove 203, groove 204, second limiting groove 205, fixing seat 206, first limiting block 207, positioning rod 208, spring 209, second limiting block 210, bolt 211, slider 212, sliding sleeve 213, clamping block 214, and connecting plate 215, in use, the base plate 1 and oil cylinder 202 are first fixed by the fixing seat 206 and bolt 211. The workpiece is positioned on the clamping body, and then the hydraulic cylinder 202 is activated to push its output end out. At the same time, the hydraulic cylinder 202 is connected to the connecting plate 215, thereby driving the slider 212 to slide along the first limiting groove 203, the sliding sleeve 213 to move along the groove 204, and the second limiting block 210 to slide inside the second limiting groove 205. At the same time, the spring 209 will deform. When the slider 212 moves upward, it drives the two sets of clamping blocks 214 to move away from each other, thereby releasing the workpiece. At the same time, when the slider 212 moves downward, it drives the two sets of clamping blocks 214 to move towards each other, thereby clamping the workpiece.

[0023] Furthermore, two sets of fixing seats 206 are provided, and the two sets of fixing seats 206 are distributed at equal intervals on the hydraulic cylinder 202. Through the setting of fixing seats 206, the fixing seats 206 are connected to the hydraulic cylinder 202 by bolts 211, which firmly installs the hydraulic cylinder 202 on the base plate 1, providing stable support and preventing the hydraulic cylinder 202 from shifting or tilting during operation.

[0024] Furthermore, two sets of grooves 204 are provided on one side of the fixing frame 201 and on both sides of the first limiting groove 203. Through the setting of the grooves 204, the grooves 204 provide a sliding path for the positioning rod 208 and the sliding sleeve 213, ensuring that they run along the predetermined trajectory during the movement of the slider 212, avoiding deviation or jamming, thereby ensuring the smoothness and accuracy of the clamping action. At the same time, the grooves 204 provide a space for fixing and fitting the positioning rod 208, the spring 209 and the sliding sleeve 213, so that the components can be stably connected and work together, thereby realizing the precise movement of the slider 212.

[0025] Furthermore, a sliding sleeve 213 is connected to the other side of the spring 209. The spring 209 is located on the outside of the positioning rod 208. Through the setting of the spring 209, the spring 209 is connected to the outside of the positioning rod 208. Through the elastic action, the spring 209 provides a return force to the sliding sleeve 213, ensuring that the slider 212 can quickly return to the initial position after completing the clamping or releasing action, restoring the initial state of the mechanism. At the same time, during the movement of the slider 212, the spring 209 absorbs and buffers the instantaneous impact force applied from the outside, avoiding damage to parts due to excessive mechanical movement or excessive force, and improving the service life and safety of the mechanism.

[0026] Furthermore, the sliding sleeve 213 is fitted inside the groove 204, and the other side of the sliding sleeve 213 is connected to the slider 212. Through the setting of the sliding sleeve 213, the sliding sleeve 213 is fitted inside the groove 204 and sleeved on the outside of the positioning rod 208, providing precise sliding guidance for it, ensuring that the slider 212 runs along the set trajectory during the movement, avoiding deviation or jamming. At the same time, the sliding sleeve 213 enhances the rigidity of the positioning rod 208 through its fitting with the positioning rod 208 and the restriction of the groove 204, preventing the positioning rod 208 from bending or deforming due to external forces, and ensuring the stability of the clamping mechanism 2.

[0027] Furthermore, the dimensions of the first limiting groove 203 and the second limiting groove 205 are matched, and the shapes of the first limiting groove 203 and the second limiting groove 205 are both stepped. Through the setting of the first limiting groove 203 and the second limiting groove 205, the first limiting groove 203 provides a sliding path for the first limiting block 207 and the slider 212, ensuring that the slider 212 moves in a predetermined direction and avoiding deviation or jamming. The second limiting groove 205 provides a fitting space for the second limiting block 210. Through the fixing of the limiting block, the precise positioning of the clamping block 214 in the initial state or during the movement process is ensured.

[0028] Furthermore, both the slider 212 and the clamping block 214 are trapezoidal in shape, forming a closed rectangular structure. Through the arrangement of the slider 212 and the clamping block 214, they work together in the entire clamping mechanism 2. The slider 212 is responsible for transmitting the power output by the hydraulic cylinder 202 and maintaining the guidance and stability of the clamping block 214, while the clamping block 214 performs the actual clamping task. The reliability and stability of the clamping effect are ensured through precise synchronous action. Together, they ensure the accuracy, stability and safety of the clamping process.

[0029] Furthermore, two sets of clamping blocks 214 are provided, and the positions of the two sets of clamping blocks 214 are relatively aligned. The other side of the connecting plate 215 is connected to the output end of the hydraulic cylinder 202. Through the setting of the connecting plate 215, one end of the connecting plate 215 is connected to the output end of the hydraulic cylinder 202, and the other end is connected to the slider 212. It acts as a bridge between the hydraulic cylinder 202 and the slider 212, thereby realizing the clamping or releasing action of the clamping block 214.

[0030] Working principle: First, the base plate 1 and the hydraulic cylinder 202 are fixed to the clamping body by the fixed seat 206 and bolts 211. Then, the hydraulic cylinder 202 is activated to push its output end out. At the same time, the hydraulic cylinder 202 is connected to the connecting plate 215, thereby driving the slider 212 to slide along the first limiting groove 203. The sliding sleeve 213 moves along the groove 204. The second limiting block 210 will slide inside the second limiting groove 205. At the same time, the spring 209 will deform. When the slider 212 moves up, it drives the two sets of clamping blocks 214 to move away from each other, thereby releasing the workpiece. At the same time, when the slider 212 moves down, it drives the two sets of clamping blocks 214 to move towards each other, thereby clamping the workpiece.

[0031] 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.
