These products are widely used in various fields such as industry, construction, transportation, and daily life due to their strength, durability, electrical conductivity, and thermal conductivity.

[0003] Traditional fastening methods rely heavily on friction for their locking mechanisms. Therefore, this method cannot precisely control the clamping load. To address these issues, we have developed a wedge-shaped locking mechanism for a quick-change hydraulic clamp. Utility Model Content

[0004] This utility model discloses a wedge locking mechanism for a quick-change hydraulic clamp. It studies and improves upon the existing structure and its shortcomings, providing a wedge locking mechanism for a quick-change hydraulic clamp to achieve better practical value.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wedge locking mechanism for a quick-change hydraulic clamp includes a mounting base, mounting blocks are fixedly connected at equal intervals to the outer side of the mounting base, a clamping plate is provided on one side of the mounting block, a first shaft is fixedly connected to one side of the clamping plate, one end of the first shaft is rotatably connected to one side of the mounting block, and an adjustment component is provided on one side of the mounting base for driving the clamping plate to rotate.

[0007] The adjustment assembly includes a hydraulic cylinder, which is disposed on one side of the mounting base. One end of the hydraulic cylinder extends to the other side of the mounting base and is fixedly connected to a movable plate. Connecting blocks are fixedly connected at equal intervals to the outer side of the movable plate.

[0008] In a preferred embodiment, the clamping plate has a first connecting groove inside, a driving link is provided on one side of the connecting block, and a second shaft is fixedly connected to one side of the driving link at equal intervals. One end of the second shaft is rotatably connected to one side of the connecting block and one side of the inner wall of the first connecting groove, respectively.

[0009] In a preferred embodiment, a clamping block is provided at the top of the clamping plate, a second connecting groove is provided inside the clamping plate, a connector is fixedly connected to one side of the clamping block, a third shaft is fixedly connected to one side of the connector, and one end of the third shaft is rotatably connected to one side of the inner wall of the second connecting groove.

[0012] In a preferred embodiment, the hydraulic cylinder is electrically connected to an external controller.

[0013] The wedge locking mechanism of the quick-change hydraulic clamp provided by this utility model has the following advantages:

[0014] Firstly, the adjustment component, by employing a hydraulic cylinder, helps to precisely control the clamping load, avoiding the uncertainty caused by relying on friction. At the same time, by driving multiple sets of clamping plates to rotate and the clamping blocks to close, it can achieve uniform clamping of the workpiece, reducing the problem of local over-tightening or over-loosening. The adjustment component not only allows the clamping pressure to be adjusted according to different workpieces, improving process flexibility, but also enables the workpiece to be quickly fixed and released, improving production efficiency.

[0015] Secondly, by setting a connector that can move within a small range inside the second connecting groove, the clamping block can fit more closely to the workpiece when clamping it, thus improving the clamping effect. By setting a balance spring to restrict the clamping block, it is ensured that the clamping block can quickly and accurately contact the workpiece when clamping it. Attached Figure Description

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0022] The wedge locking mechanism of the quick-change hydraulic clamp disclosed in this utility model is mainly used in the production of metal products.

[0023] Reference Figures 1 to 4 A wedge locking mechanism for a quick-change hydraulic clamp includes: a mounting base 1, mounting blocks 2 are fixedly connected at equal intervals to the outer side of the mounting base 1, a clamping plate 3 is provided on one side of the mounting block 2, a first shaft 4 is fixedly connected to one side of the clamping plate 3, one end of the first shaft 4 is rotatably connected to one side of the mounting block 2, and an adjustment component is provided on one side of the mounting base 1 for driving the clamping plate 3 to rotate.

[0024] The adjustment assembly includes a hydraulic cylinder 5, which is located on one side of the mounting base 1. One end of the hydraulic cylinder 5 extends to the other side of the mounting base 1 and is fixedly connected to a movable plate 6. Connecting blocks 7 are fixedly connected at equal intervals to the outer side of the movable plate 6.

[0025] A clamping block 12 is provided on the top of the clamping plate 3. A second connecting groove 11 is provided inside the clamping plate 3. A connector 13 is fixedly connected to one side of the clamping block 12. A third shaft 14 is fixedly connected to one side of the connector 13. One end of the third shaft 14 is rotatably connected to one side of the inner wall of the second connecting groove 11.

[0026] A balance spring 15 is fixedly connected between the clamping block 12 and one side of the clamping plate 3;

[0027] In a preferred embodiment, a protective shell 16 is provided on the outside of the hydraulic cylinder 5, and two flanges 17 are fixedly connected to the outside of the protective shell 16, one of which is installed to the mounting base 1 by screws.

[0028] In the above technical solution, considering that the locking mechanism of the traditional fastening method relies heavily on friction, this method cannot accurately control the clamping load. To solve this problem, the specific operation is as follows: The clamp is installed in the designated position using flange 17. Then, the workpiece is placed between multiple sets of clamping blocks 12. Using the adjusting component, the hydraulic cylinder 5 is activated to retract, thereby driving the movable plate 6 and connecting block 7 to move towards the mounting base 1. Through the driving connecting rod 9, the multiple sets of clamping plates 3 rotate around the first shaft 4, bringing them closer together. This, in turn, moves the clamping blocks 12 closer to the workpiece and clamps it, facilitating subsequent processing of the workpiece. The adjustment component, employing a hydraulic cylinder 5, helps to precisely control the clamping load, avoiding uncertainties caused by relying on friction. Simultaneously, by driving multiple sets of clamping plates 3 during rotation and the closing of the clamping blocks 12, it achieves uniform clamping of the workpiece, reducing localized over-tightening or over-loosening. The adjustment component not only allows for adjustment of clamping pressure according to different workpieces, improving process flexibility, but also enables rapid workpiece fixing and release, increasing production efficiency. By setting a connector 13 that can move within a small range inside the second connecting groove 11, the clamping blocks 12 can better fit the workpiece when clamping, improving the clamping effect. By setting a balance spring 15, the clamping blocks 12 are restricted, ensuring that they can quickly and accurately contact the workpiece when clamping it.

[0029] Reference Figures 1 to 4 In a preferred embodiment, the hydraulic cylinder 5 is electrically connected to an external controller;

[0030] Working principle: In use, the clamp is installed in the designated position using flange 17. Then, the workpiece is placed between multiple sets of clamping blocks 12. Using the adjusting component, the hydraulic cylinder 5 is activated to retract, thereby driving the movable plate 6 and connecting block 7 to move towards the mounting base 1. Through the driving connecting rod 9, the multiple sets of clamping plates 3 are driven to rotate around the first shaft 4, bringing them closer together. This causes the clamping blocks 12 to move closer to the workpiece and clamp it, facilitating subsequent processing of the workpiece. Finally, the hydraulic cylinder 5 is activated again to extend, causing the clamping plates 3 to open and the clamping blocks 12 to separate from the workpiece, allowing the workpiece to be removed. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0031] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
