Description

Technical Field

[0001] The utility model relates to the technical field of die clamping devices, in particular to an automatic displacement die clamping device. Background Art

[0002] In modern industrial production, the clamping and positioning accuracy of molds plays a crucial role in product quality and production efficiency. Traditional mold clamps often suffer from problems such as inconvenient operation, low positioning accuracy, and low automation.

[0003] Conventional clamps may rely on manual operation, which is not only labor-intensive but also difficult to ensure consistent and accurate clamping. Furthermore, some clamps lack precise displacement control, making them incapable of meeting the demands of high-precision machining.

[0004] For example, some simple mechanical clamps have crude displacement adjustment methods, making it difficult to achieve subtle and precise position adjustments. Other clamps use manual control, which is cumbersome and inefficient to operate and prone to errors caused by human error.

[0005] With the continuous development of industrial automation, the demand for clamps capable of automatic displacement and high-precision clamping is becoming increasingly urgent. This demand has driven the research and development and innovation of related technologies, leading to the birth of automatic displacement clamps. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example

[0024] like Figure 1-3As shown, an automatic displacement clamp proposed in one embodiment of the present invention includes a translation mechanism, which is composed of a base plate 1, a servo motor 2 is fixedly connected to one side of the base plate 1, a threaded rod 3 is fixedly connected to the output end of the servo motor 2, a threaded block 5 is threadedly connected to the threaded rod 3, a positioning rod 4 is movably connected to the threaded block 5, a base 6 is fixedly connected to the threaded block 5, a card shell 7 is fixedly connected to the base 6, a fixed end of a hydraulic cylinder 8 is rotatably connected to the card shell 7, the output end of the hydraulic cylinder 8 is rotatably connected to a connecting sleeve 9, the connecting sleeve 9 is rotatably connected to a force arm 10, one end of the force arm 10 is engaged with a die pressing head 11, a fixing part 12 is fixedly installed inside the card shell 7, and a connecting part 13 is rotatably connected to the fixing part 12;

[0025] This automatic displacement clamp primarily consists of a translation mechanism. A base plate 1 serves as the foundation, while a servo motor 2 mounted on one side provides power for the entire device. Rotation of a threaded rod 3 connected to the output of the servo motor 2 moves a threaded block 5 threadedly attached to it.

[0026] The positioning rod 4 inserted into the threaded block 5 plays a positioning and guiding role, ensuring that the threaded block 5 moves along a predetermined linear direction. The base 6 on the threaded block 5 is used to carry subsequent components.

[0027] The jamb 7 on the base 6 is the installation basis of other components. The hydraulic cylinder 8 that is rotatably connected on the jamb 7 can drive the movement of related components through the expansion and contraction of the output end.

[0028] The connecting sleeve 9 rotatably connected to the output end of the hydraulic cylinder 8 is used to transmit motion, and the connecting sleeve 9 is rotatably connected to the lever arm 10, thereby enabling the lever arm 10 to move. The die pressing head 11 assembled at one end of the lever arm 10 is used to clamp or operate the mold.

[0029] The fixing member 12 inside the housing 7 and the connecting member 13 rotatably connected thereto play the role of stabilizing and assisting movement.

[0030] Here's how it works:

[0031] When clamping is required, servo motor 2 is activated, and its output drives threaded rod 3 to rotate. Because threaded block 5 is threadedly connected to threaded rod 3 and guided by positioning rod 4, threaded block 5 moves linearly along threaded rod 3, driving base 6 and its connected components to translate as a whole, achieving horizontal position adjustment of the clamp.

[0032] When the clamp reaches the desired position, hydraulic cylinder 8 begins to operate. The output end of hydraulic cylinder 8 expands and contracts, driving power arm 10 to rotate through connecting sleeve 9. The ram 11 at one end of power arm 10 then moves, clamping or releasing the mold.

[0033] During the entire process, the fixing member 12 and the connecting member 13 play the role of stabilizing the structure and assisting the movement of the lever arm 10, thereby ensuring the accuracy and stability of the mold clamping operation.

[0034] like Figure 1 As shown, in some embodiments, both ends of the threaded rod 3 are rotatably connected to the base plate 1 via bearings. This design enables the threaded rod 3 to rotate freely on the base plate 1 .

[0035] like Figure 2 As shown, in some embodiments, there are two positioning rods 4, both ends of which are fixed on the base plate 1 respectively, to position and guide the threaded block 5. Its main function is to provide accurate direction guidance and position limitation for the movement of the threaded block 5.

[0036] like Figure 3 As shown, in some embodiments, one end of the connecting member 13 is rotatably connected to the connecting sleeve 9. This rotatable connection design enables the connecting member 13 to rotate relative to the connecting sleeve 9, thereby better transmitting motion and force during the operation of the automatic displacement clamp and coordinating with other components to complete corresponding actions.

[0037] like Figure 3 As shown, in some embodiments, one end of the lever arm 10 is rotatably connected to the fixing member 12 . This connection method allows the lever arm 10 to rotate on the fixing member 12 .

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
