Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, and in particular to a magnetoelastic fusion adaptive precise and stable adsorption device. Background Art

[0002] In the field of robotic fixation, traditional methods such as magnetic attachment, electro-permanent magnetic attachment, mechanical fixation, and adhesive fixation generally suffer from limited fixation capacity, high energy consumption, complex operation, and poor applicability. While these methods provide stable attachment, they are often accompanied by drawbacks such as heavy weight, high energy consumption, and insufficient flexibility, making them unable to meet the requirements of modern robotic operations for high efficiency, energy conservation, and environmental protection. The limitations of these traditional fixation technologies are particularly evident in specialized working environments, such as marine engineering and precision manufacturing. Utility Model Content

[0003] In response to the above problems, a flexibly adjustable magneto-elastic fusion adaptive precise and stable adsorption device is provided to meet the high efficiency requirements of robot fixation technology.

[0004] The specific technical solutions are as follows:

[0005] A magnetic-elastic fusion adaptive precise and stable adsorption device includes: a flange, a sliding rod and a lower elastic part. The sliding rod is installed on the flange in an upward and downward sliding manner. An electromagnetic adsorption part is installed at the bottom of the sliding rod. The electromagnetic adsorption part can abut against the working surface under the action of the lower elastic part.

[0006] Furthermore, the adsorption device also includes an upper elastic member, two ends of which are correspondingly mounted on the sliding rod and the flange.

[0007] Furthermore, a threaded portion is installed on the upper portion of the sliding rod, an adjusting nut is spirally installed on the threaded portion, and the upper end of the upper elastic member is installed on the adjusting nut.

[0008] Furthermore, the upper elastic member and the lower elastic member have different elastic coefficients.

[0009] Furthermore, the lower elastic member is a spring or an elastic sheet.

[0010] Furthermore, the lower elastic member is a lower elastic spring, which is passed through the sliding rod, and two ends of the lower elastic spring correspondingly abut against the flange and the electromagnetic adsorption member.

[0011] Furthermore, the upper elastic member is a spring or an elastic sheet.

[0012] Furthermore, the upper elastic member is an upper elastic spring, which is passed through the sliding rod, and two ends of the upper elastic spring correspondingly abut against the flange and the adjusting nut.

[0013] The beneficial effects of the above scheme are:

[0014] The dual elastic member design in the utility model allows each elastic member to be independently compressed and stretched according to the unevenness of the working surface or the dynamic changes caused by the robot movement, thereby achieving dynamic balance. This balance helps to quickly adjust and stabilize the adsorption force and reduce displacement caused by vibration. At the same time, the dual elastic members can also provide better response to different vibration frequencies and reduce the system's sensitivity to specific frequencies.

[0017] The following will be combined with 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 any creative work are within the scope of protection of the present invention.

[0018] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0019] The present invention will be further described below with reference to specific embodiments, but this is not intended to limit the present invention.

[0020] like Figure 1 As shown, the magnetic-elastic fusion adaptive precise and stable adsorption device provided in the embodiment of the present invention includes a flange 1, a sliding rod 4 and a lower elastic member 5. The sliding rod 4 is inserted into the flange 1, and an electromagnetic adsorption member 6 is installed at the bottom of the sliding rod 4. In the prior art, there are technical solutions or technical concepts that directly utilize the adsorption effect of the electromagnetic adsorption member 6 on the flange 1 to fasten and adsorb the flange 1 on the working surface. However, there is a problem that the electromagnetic adsorption member 6 cannot effectively adsorb the working surface when the working surface fluctuates. Therefore, the present invention is designed with a lower elastic member 5. The electromagnetic adsorption member 6 can always abut against the working surface under the action of the lower elastic member 5. Combined with the adsorption effect of the electromagnetic adsorption member 6, the flange 1 can be effectively fixed on the working surface, avoiding problems such as the flange 1 and the supporting devices carried thereon being accidentally dropped due to the fluctuation of the working surface, which causes the electromagnetic adsorption member 6 to be unable to effectively adsorb the working surface.

[0021] The lower elastic member 5 in the present invention is a spring or an elastic sheet, and preferably a lower elastic spring composed of a spring. When in use, the lower elastic spring is passed through the sliding rod 4, and the two ends of the lower elastic spring correspondingly abut against the flange 1 and the electromagnetic adsorption member 6. The above-mentioned passing structure can increase the overall stability of the adsorption device.

[0022] On the basis of the above technical solution, further, the adsorption device provided in this embodiment also includes an upper elastic member 3, whose two ends are correspondingly mounted on the sliding rod 4 and the flange 1. The above-mentioned upper elastic member 3 and the lower elastic member 5 constitute a double elastic member design, so that each elastic member can be independently compressed and stretched according to the unevenness of the working surface or the dynamic changes caused by the movement of the robot, thereby achieving dynamic balance. This balance helps to quickly adjust and stabilize the adsorption force and reduce the displacement caused by vibration; at the same time, the double elastic member can also reduce the resonance phenomenon by providing additional damping (the two elastic members can offset part of the vibration energy of each other) and reduce the sensitivity of the system to specific frequencies; at the same time, the double elastic member design also helps to maintain uniform pressure between the flange 1 and the working surface, which helps to reduce local vibration and noise caused by uneven pressure, thereby improving the overall damping effect. In the present utility model, the upper elastic member 3 is a spring or an elastic sheet, and is preferably an upper elastic spring composed of a spring. When in use, the upper elastic spring is passed through the sliding rod 4. The above-mentioned passing structure can increase the overall stability of the adsorption device.

[0023] It should be noted that, based on the aforementioned dual-elastic member design, the elastic coefficients of the upper and lower elastic springs in the present invention can be the same or different. When the two are the same or different, a threaded portion can be provided on the upper portion of the sliding rod 4, and an adjustment nut 2 can be screwed onto the threaded portion. In this case, the upper end of the upper elastic member 3 can directly abut the adjustment nut 2, thereby adjusting the elastic force of the upper elastic member 3 through the adjustment nut 2 (the two ends of the upper elastic spring correspondingly abut the flange 1 and the adjustment nut 2), thereby adjusting the overall damping effect of the upper and lower elastic springs.

[0024] The above are only preferred embodiments of the present invention and do not limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the contents of the present invention specification should be included in the protection scope of the present invention.
