[0002] In the field of industrial automation and logistics warehousing, target grabbing mechanism plays a crucial role.

[0003] Traditional grabbing mechanisms often have problems such as complex installation, difficult adjustment, low grabbing efficiency, and missed or missed grabbing, which not only affect production efficiency, but also increase operation risk and maintenance cost. UTILITY MODEL CONTENT

[0004] The utility model aims at providing a multifunctional spare part target grabbing mechanism to solve the problems of grabbing spare parts and mechanical arm installation in the prior art.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0006] A multifunctional spare part target grabbing mechanism, comprising a mounting disc, four downward opening stepped grooves are equidistantly provided around the mounting disc, a plurality of mounting holes are provided through the two sides of the stepped groove, an axle block is installed in the stepped groove, a ladder plate cooperating with the stepped groove is arranged at the bottom of the axle block, and a grabbing arm is hingedly connected to the axle block; a lifting motor is installed at the center of the mounting disc, a lifting shaft is installed in the lifting motor, a linkage mechanism is installed at the top of the lifting shaft, and the linkage mechanism is used to pull the grabbing arm to rotate.

[0007] Further, the top of the grabbing arm is provided with a mounting groove, and a clamping head is installed in the mounting groove. The clamping head is directed to the center of the mounting disc, and the use of the clamping head helps to ensure that the grabbing arm maintains the correct angle and force when grabbing the target object. This reduces the risk of grabbing failure or object damage due to improper grabbing angle or insufficient force, and improves the stability and accuracy of grabbing. The design of the mounting groove makes the replacement of the clamping head simple and fast. When the clamping head needs to be replaced due to wear, damage or the need to adapt to different tasks, only the old clamping head needs to be disassembled and the new clamping head needs to be installed, without the need to make large-scale changes to the entire grabbing arm. This reduces maintenance costs and improves work efficiency.

[0008] Further, one end of the clamping head is provided with anti-slip lines. When the grabbing arm grabs the article, the anti-slip lines contact the outer wall of the article, which can increase the friction between the clamping head and the outer wall of the article, thereby preventing the article from slipping or moving during the grabbing process. This design is particularly suitable for grabbing articles with smooth surfaces or materials that are not easy to fix, ensuring the stability and reliability of the grabbing process.

[0009] Further, the linkage mechanism comprises a connecting head mounted at the top end of the lifting shaft, and four mounting arms are equidistantly distributed around the connecting head. The linkage mechanism further comprises a hydraulic cylinder mounted inside the grabbing arm, and a hydraulic rod is mounted in the hydraulic cylinder and hingedly connected to the mounting arm at one end.

[0010] The technical scheme of the utility model has the following beneficial effects:

[0011] 1. The whole is installed and used in a convenient dismounting mode, which can facilitate replacement of the grabbing arms or change of the mounting positions of the grabbing arms, thereby adjusting the grabbing stroke of the grabbing arms, reducing the possibility of mistaken or missed grabbing, improving the grabbing efficiency and accuracy, and facilitating grabbing of loose parts.

[0012] 2. The four grabbing arms are mounted on the connecting head through the hydraulic rod, which can ensure that the four grabbing arms move simultaneously when the lifting shaft moves, ensure the stability of clamping, and improve the response speed and movement precision of the equipment.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical scheme and advantages of the utility model more clear, the following will combine the drawings and embodiments to further illustrate the utility model. It should be understood that the specific embodiments described herein are only used to explain the utility model, and are not used to limit the utility model. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0019] Embodiment one:

[0020] ReferenceFigure 1 and Figure 3 The multifunctional scattered part target grabbing mechanism comprises a mounting disc 10, four downward-opening stepped grooves 11 are equidistantly arranged around the mounting disc 10, a plurality of mounting holes 12 are arranged through the two sides of the stepped groove 11, an axle block 13 is mounted in the stepped groove 11, a ladder plate 14 is arranged at the bottom of the axle block 13 and cooperates with the stepped groove 11, and a grabbing arm 15 is hingedly connected to the axle block 13.

[0021] In the above scheme, the mounting disc 10 is in a circular structure, the stepped groove 11 extends to the center of the mounting disc 10, when the axle block 13 is mounted, only the ladder plate 14 needs to be clamped in the stepped groove 11, the plurality of mounting holes 12 are parallelly arranged on the two sides of the stepped groove 11, the bolt is simultaneously passed through the mounting hole 12 and the axle block 13, therefore, the position of the axle block 13 can be adjusted in the stepped groove 11, so as to adjust the distance from the grabbing arm 15 to the center of the mounting disc 10, the grabbing arm 15 is hingedly connected, each grabbing arm 15 is simultaneously rotated to the center of the mounting disc 10, which is the grabbing of the target, and vice versa.

[0022] In summary, the whole is installed and used in a convenient dismounting mode, which can facilitate the replacement of the grabbing arm 15 or the change of the mounting position of the grabbing arm 15, so as to adjust the grabbing stroke of the grabbing arm 15, reduce the possibility of mistaken grabbing or missed grabbing, and improve the grabbing efficiency and accuracy. It can be widely applied to industrial automation, logistics and warehousing, and the use of the four grabbing arms 15 is also beneficial to scattered part grabbing.

[0023] Further reference Figure 1 The top of the grabbing arm 15 is provided with a mounting groove 16, and a clamping head 17 is mounted in the mounting groove 16.

[0024] In a further embodiment, the clamping head 17 faces the center of the mounting disc 10, and the use of the clamping head 17 helps to ensure that the grabbing arm 15 maintains the correct angle and force when grabbing the target object. This reduces the risk of grabbing failure or object damage due to improper grabbing angle or insufficient force, and improves the stability and accuracy of grabbing. The design of the mounting groove 16 makes the replacement of the clamping head 17 simple and fast. When the clamping head 17 needs to be replaced due to wear, damage or the need to adapt to different tasks, only the old clamping head 17 needs to be disassembled and the new clamping head 17 needs to be mounted, without the need to make large-scale modifications to the whole grabbing arm 15. This reduces maintenance costs and improves work efficiency.

[0025] Further reference Figure 1The end of the clamping head 17 is provided with anti-skid lines 18. When the grabbing arm 15 grabs the object, the anti-skid lines 18 are in contact with the outer wall of the object, so that the friction between the clamping head 17 and the outer wall of the object is increased, thereby preventing the object from slipping or moving during the grabbing process. This design is particularly suitable for grabbing objects with smooth surfaces or objects with materials that are not easy to fix, thereby ensuring the stability and reliability of the grabbing process.

[0026] Reference Figure 1 and Figure 2 The lifting motor 20 is installed at the center of the mounting disc 10, the lifting shaft 21 is installed in the lifting motor 20, the linkage mechanism is installed at the top of the lifting shaft 21, and the linkage mechanism is used to pull the rotating of the grabbing arm 15. The linkage mechanism comprises a connecting head 22, the connecting head 22 is installed at the top end of the lifting shaft 21, four mounting arms 23 are equidistantly distributed around the connecting head 22. The linkage mechanism further comprises a hydraulic cylinder 24, the hydraulic cylinder 24 is installed on the inner side of the grabbing arm 15, the hydraulic rod 25 is installed in the hydraulic cylinder 24, and one end of the hydraulic rod 25 is hingedly connected with the mounting arm 23.

[0027] In the above scheme, when the lifting motor 20 is started, the hydraulic rod 25 is extended in the hydraulic cylinder 24 when the lifting shaft 21 moves upwards, so that the grabbing arm 15 is rotated outward, and vice versa. The grabbing arm 15 is rotated inward to grab the target. The four grabbing arms 15 are installed on the connecting head 22 through the hydraulic rod 25, which can ensure that the four grabbing arms 15 move simultaneously when the lifting shaft 21 moves, thereby ensuring the stability of the clamping and improving the response speed and motion accuracy of the equipment.

[0028] The specific implementation process of the utility model is as follows:

The mounting holes 12 are parallelly distributed on the two sides of the ladder groove 11, and the bolts are simultaneously inserted through the mounting holes 12 and the shaft block 13. Therefore, the position of the shaft block 13 can be adjusted in the ladder groove 11, so as to adjust the distance between the grabbing arm 15 and the center of the mounting disc 10. By starting the lifting motor 20, when the lifting shaft 21 moves upwards, the hydraulic rod 25 is extended in the hydraulic cylinder 24, so that the grabbing arm 15 is rotated outward, and vice versa. The grabbing arm 15 is rotated inward to grab the target.
