Description

Technical Field

[0001] The utility model relates to the technical field of clamping devices, specifically a hydraulic clamping device. Background Art

[0002] A hydraulic clamping device is a device that uses the hydraulic principle to clamp a mold, usually composed of components such as a hydraulic cylinder, a piston rod, and a clamping arm. It has the advantages of large clamping force, reliable clamping, and stable operation, and is widely used in various mold clamping occasions.

[0003] The working principle of the hydraulic clamping device is that the piston rod of the hydraulic cylinder extends, pushing the clamping arm to rotate around the fulcrum, so as to achieve the purpose of clamping the mold. When it is necessary to loosen the mold, the piston rod of the hydraulic cylinder retracts, and the clamping arm rotates in the reverse direction to loosen the mold.

[0004] The hydraulic clamping device mainly fixes the mold: it can firmly hold the mold on the workbench, prevent the mold from shifting or loosening during the production process, and ensure the accuracy and stability of processing.

[0005] On some fully automated production lines, the hydraulic clamping device can automatically complete the clamping action according to the preset program without manual intervention.

[0006] Therefore, we propose a hydraulic clamping device to solve the above problems. Content of the Utility Model

The third force arm 12 is rotatably connected to a clamping film plate 15 through the connecting member 14;

[0026] Rotating device:

[0027] Housing 1: Provides support and protection for various internal components.

[0028] Servo motor 2: As a power source, provides precise rotational driving force.

[0029] Worm 3: Cooperates with the worm wheel 4 to achieve speed reduction and power transmission, making the rotation smoother and more precise.

[0030] Worm wheel 4: Meshes with and drives the worm 3, driving the rotating disk 5 to rotate.

[0031] Rotating disk 5: Connects to the mounting seat 6 to achieve the overall rotation action.

[0032] Mounting seat 6: Used for installing and fixing other components.

[0033] Base 7: Provides basic support to ensure the stability of the overall structure.

[0034] First force arm 8: Can rotate around the base 7 to achieve a certain angle adjustment.

[0035] First hydraulic rod 9: Drives the action of the first force arm 8 through telescoping, thereby changing its position and posture.

[0036] Second force arm 10: Cooperates with the first force arm 8 to further expand the action range.

[0037] Second hydraulic rod 11: Controls the movement of the second force arm 10 to enable flexible position adjustment.

[0038] The third force arm 12: continues to extend to increase the diversity of actions.

[0039] The third hydraulic rod 13: drives the third force arm 12 to achieve finer adjustments.

[0040] The connecting piece 14: connects the third force arm 12 and the film clamping plate 15 and plays a transitional role.

[0041] The film clamping plate 15: the component that finally executes the mold clamping action;

[0042] Working principle:

[0043] Start the servo motor 2, the output end of which drives the worm 3 to rotate. The worm 3 then drives the meshing worm wheel 4 to rotate, and the worm wheel 4 drives the rotating disc 5 to rotate, thereby realizing the rotational movement of the rotating device.

[0044] On the basis of rotation, by controlling the extension and retraction of the first hydraulic rod 9, the angle and position of the first force arm 8 relative to the base 7 can be changed. When the first hydraulic rod 9 extends or retracts, it will push or pull the first force arm 8 to rotate around its connection point with the base 7.

[0045] The second force arm 10 cooperates with the first force arm 8, and the extension and retraction of the second hydraulic rod 11 can control the movement of the second force arm 10. The third force arm 12 is connected to the second force arm 10, and the extension and retraction of the third hydraulic rod 13 can drive the movement of the third force arm 12.

[0046] Finally, through the connection between the third force arm 12 and the connecting piece 14, the action is transmitted to the film clamping plate 15 to realize the fastening or loosening action of the mold. Through the coordinated action of each hydraulic rod and force arm, as well as the rotation function of the rotating device, the hydraulic mold clamp can precisely adjust and clamp the mold in multiple directions and angles.

[0047] As Figure 2 shown, in some embodiments, the rotating disc 5 is rotatably connected inside the housing 1; this means that the rotating disc 5 can rotate smoothly relative to the housing 1. The housing 1 provides a space for installing and protecting the rotating disc 5 and also plays a certain supporting role.

[0048] As Figure 3 shown, in some embodiments, the fixed end of the first hydraulic rod 9 rotates on the first force arm 8, and the output end of the first hydraulic rod 9 is rotatably connected to the base 7; when the first hydraulic rod 9 acts, since its fixed end rotates on the first force arm 8 and the output end is rotatably connected to the base 7, the extension and retraction of the first hydraulic rod 9 can drive the first force arm 8 to rotate relative to the base 7.

[0049] As Figure 3As shown, in some embodiments, the fixed end of the second hydraulic rod 11 rotates on the first force arm 8, and the output end of the second hydraulic rod 11 is rotatably connected to the second force arm 10. This design enables the second hydraulic rod 11 to effectively control the movement of the second force arm 10 relative to the first force arm 8.

[0050] As Figure 3 As shown, in some embodiments, the fixed end of the third hydraulic rod 13 rotates on the third force arm 12, and the output end of the third hydraulic rod 13 rotates on the second force arm 10. When the third hydraulic rod 13 operates, since its fixed end is rotatably connected to the third force arm 12 and the output end is rotatably connected to the second force arm 10, the telescopic movement of the third hydraulic rod 13 can cause the third force arm 12 to rotate correspondingly relative to the second force arm 10.

[0051] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features.
