[0002] In the field of automated assembly, workpieces often need to be gripped, rotated, and tightened. These operations are crucial for improving production efficiency and product quality, particularly in industries such as automotive, electronics, and mechanical manufacturing. Traditional assembly methods often rely on mechanical fixtures or manual labor, but these methods suffer from inefficiencies, high costs, and difficulty adapting to workpieces of varying shapes and sizes.

[0003] Existing technologies for gripping, rotating, and tightening workpieces with holes, such as nuts, typically use vacuum adsorption or mechanical clamping. However, these methods often present the following challenges when handling heavy or unusually shaped nuts:

[0004] Insufficient grasping stability: When grasping workpieces with holes, the traditional vacuum adsorption method is prone to air leakage due to the presence of holes, resulting in unstable grasping force and affecting subsequent rotation and tightening operations.

[0005] In summary, the existing technology still has many shortcomings in the grasping, rotating and tightening operations of workpieces with holes such as nuts, especially in terms of grasping stability and operating convenience, which need further improvement.

[0006] For this purpose, we propose the pick-up vacuum nut socket. Utility Model Content

[0007] To address the shortcomings of the aforementioned existing production technologies, the applicant has developed a vacuum nut pick-up sleeve.

[0015] It is further characterized by:

[0016] The front section of the sleeve also includes: a workpiece accommodating cavity, which is opened on the open side of the front section of the sleeve and is used to accommodate and limit the rotation of the workpiece.

[0017] The shape of the workpiece accommodating cavity matches the workpiece, so that after the workpiece is adsorbed, it is placed in the accommodating cavity by compression for rotational installation.

[0018] The air channel in the rear section of the sleeve is used to transport the vacuum airflow transmitted by the vacuum equipment to the front section of the sleeve.

[0019] A step groove is provided in the first cavity, and the expanded portion of the side wall of the nail-absorbing tube cooperates with the step groove to ensure that the nail-absorbing tube will not separate from the front section of the sleeve.

[0034] The specific implementation of the present utility model will be described below with reference to the accompanying drawings.

[0035] like Figure 1-Figure 2As shown, this embodiment discloses a pickup-type vacuum nut sleeve, which mainly includes the following components: a sleeve rear section 600, a sleeve front section 100, a nail suction tube 200, a nail suction head 300, and a nail suction return spring 400. The sleeve rear section 600 connects the rotating device and the vacuum device, transmitting the torque output from the rotating device. At the same time, it is provided with an air channel 601 leading to the sleeve front section 100 for conveying the vacuum airflow transmitted by the vacuum device.

[0036] The front section 100 of the sleeve is fixedly connected to the rear end 600 of the sleeve by threads, and other methods such as clamping are also possible. A first cavity connected to the air channel 601 is opened in the front section 100 of the sleeve, and a step groove is provided in the first cavity. By transmitting vacuum and guiding the reciprocating motion of the nail suction tube, the nail suction and the bolt screw are avoided. B. The internal hexagonal screw transmits the torque from the rear section of the sleeve to the nut for tightening.

[0037] In this embodiment, Figure 1 and Figure 2 As shown, the nail-absorbing tube 200 is arranged in the first cavity of the front section 100 of the sleeve. A section of the side wall of the nail-absorbing tube 200 expands outward and cooperates with the step groove. A limiting structure that cooperates with the step groove can also be fixedly connected to the nail-absorbing tube 200 to ensure that the nail-absorbing tube 200 will not be separated from the front section 100 of the sleeve.

[0038] At the same time, a second cavity arranged axially is provided on the ceiling tube 200, and a step groove is also provided in the second cavity. Both sides of the nail suction tube 200 are open to facilitate gas circulation. At the same time, one end of the nail suction tube 200 extending out of the front section 100 of the sleeve is in contact with the end face of the workpiece 700. If the part does not have a through hole, the clamping can be completed at this time.

[0039] However, the workpiece 700 in this embodiment is a nut with a through hole in the middle, so the vacuum adsorption of the nail suction tube 200 alone is not sufficient to clamp the nut workpiece and perform subsequent rotation.

[0040] In this embodiment, in order to facilitate the clamping and rotation of the nut workpiece, a nail suction head 300 is designed, which is arranged in the second cavity of the nail suction tube 200, and a stepped shaft 301 is connected to the outer wall of the nail suction head 300. The step groove of the second cavity is arranged on the moving path of the step shaft 301. The nail suction head 300 is used to block the central through hole of the nut workpiece to prevent air leakage, and cooperates with the nail suction tube 200 to assist in nail suction.

[0041] At the same time, in order to further improve the connection effect between the nail suction head 300 and the nut, a magnet 500 is installed inside the end of the nail suction head 300 close to the nut workpiece, so as to assist the vacuum suction of the heavier nut workpiece through magnetic attraction.

[0042] The nail suction return spring 400 is arranged in the first cavity. One end of the nail suction return spring 400 abuts against the rear section 600 of the sleeve, and the other end extends into the second cavity and abuts against the step shaft 301. When it is necessary to release the workpiece 700 or perform the next picking operation, the nail suction return spring 400 will push the nail suction head 300 and the nail suction tube 200 back to the initial position to ensure the normal operation of the sleeve.

[0043] In this embodiment, the side of the front section 100 of the sleeve close to the workpiece is open, and a workpiece accommodating cavity 101 for conveniently accommodating the workpiece 700 is opened on the open side of the front section 100 of the sleeve. The workpiece accommodating cavity 101 matches the shape of the workpiece 700 and can limit the rotation of the workpiece 700. After the nail suction tube 200 absorbs the workpiece 700, the workpiece 700 is placed in the accommodating cavity 101 by compression. At this time, the rotating device drives the rear section 600 of the sleeve to rotate, and can also drive the workpiece 700 for rotational installation, thereby increasing the overall torque.

[0044] The specific working principles include:

[0045] How Picking Works

[0046] When the vacuum device is activated, it creates a negative pressure environment that is transferred to the first cavity of the sleeve front section 100 through the air passage 601 in the sleeve rear section 600.

[0047] The negative pressure in the first cavity is further transferred to the second cavity of the nail-absorbing tube 200. During this process, the nail-absorbing tube 200 moves axially in the front section 100 of the sleeve to ensure that the vacuum can be smoothly transferred to the interior thereof.

[0048] When sufficient negative pressure is formed in the second cavity, the nail suction head 300 in the nail suction tube 200 will fit tightly against the nut workpiece 700. Due to the effect of vacuum, the nut workpiece is firmly adsorbed on the nail suction head 300, ready for subsequent rotation or movement operations.

[0049] In order to enhance the adsorption effect, especially for heavy nut workpieces, a magnet 500 is further installed in the nail suction head 300. The magnet further assists the vacuum adsorption of the nut workpiece through magnetic attraction to ensure its stability during operation.

[0050] How rotation works:

[0051] The sleeve rear section 600 is connected to the rotating device, and when the rotating device starts, it will produce a rotational torque. This torque is transmitted to the sleeve front section 100 and the nail suction pipe 200 and the nail suction head 300 connected thereto through the sleeve rear section 600.

[0052] Since the nail suction head 300 has firmly attracted the nut workpiece 700, the nut workpiece will rotate when the rotational torque is transmitted to the nail suction head 300. In this process, the workpiece accommodating cavity 101 plays a role in limiting the rotation range of the nut workpiece, ensuring the accuracy of rotation.

[0053] When the nut workpiece needs to be released or the next operation is performed, the nail suction return spring 400 comes into play. It pushes the nail suction head 300 and the nail suction tube 200 back to the initial position, and the vacuum device stops working, the negative pressure disappears, and the nut workpiece is released.

[0054] In this embodiment, the pick-up type vacuum nut sleeve has the following advantages:

[0055] Improve work efficiency and accuracy:

[0056] The pick-up vacuum nut sleeve uses a vacuum suction mechanism to quickly and accurately pick up nuts, significantly reducing the time and effort required for traditional manual picking. Furthermore, its precise mechanical transmission mechanism ensures accuracy during nut rotation and installation, improving overall work efficiency and product quality. This tool is particularly suitable for automated production lines, significantly improving production cycle times and reducing labor costs.

[0057] Enhanced scope of application and practicality:

[0058] The Pickup Vacuum Nut Socket is designed to accommodate nut workpieces of varying sizes and weights. By adjusting the vacuum suction force and utilizing a magnet, the tool can easily handle nuts of varying sizes, enhancing its applicability and practicality. Whether in automotive manufacturing, aerospace, or other precision assembly fields, the Pickup Vacuum Nut Socket leverages its unique advantages to meet diverse production needs.

[0059] In summary, the pick-up vacuum nut sleeve, as an innovative tool, demonstrates significant advantages for picking up and rotating parts with holes. It not only improves work efficiency and accuracy, but also expands its scope of application and practicality, simplifies the operating process, and reduces labor intensity. Furthermore, its stable structure and reliable performance enhance product stability and reliability. These benefits make the pick-up vacuum nut sleeve promising for broad application in automated production lines and precision assembly, bringing significant convenience and benefits to industrial production.
