Description

Technical Field

[0001] This utility model relates to the field of gripper technology, specifically to a novel gripper mechanism for an aluminum profile stretching machine. Background Technology

[0002] In existing aluminum profile stretching machines, the grippers are mounted piece by piece on a shaft, secured by a cylindrical key. A cylinder extends and retracts, rotating the gripper shaft and moving the grippers. This structure suffers from a small force-bearing surface between the grippers and the cylindrical key during operation, making the key prone to wear and causing varying degrees of gripper sagging. This results in a short service life and negatively impacts profile stretching. Furthermore, the presence of a notch between the stretching machine body and the grippers poses a safety hazard during gripper movement.

[0003] Based on this, this utility model designs a novel gripper mechanism for an aluminum profile stretching machine to solve the above problems. Utility Model Content

[0004] To address the aforementioned shortcomings of existing technologies, this invention provides a novel gripper mechanism for an aluminum profile stretching machine. It replaces the cylindrical key connection with a drive shaft and drive arm structure, solving the problem of gripper sagging caused by cylindrical key wear. The newly designed gripper is connected to the gripper shaft, and the drive arm cooperates with the gripper shaft, improving gripper stability and extending service life. Furthermore, the drive arm structure eliminates any cutting edges between the gripper and the stretching machine, thus eliminating safety hazards.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A novel gripper mechanism for an aluminum profile stretching machine includes a stretching machine base, a gripper shaft, and grippers, as well as a drive arm and a drive shaft. The grippers are connected to the gripper shaft. The drive arm is mounted on both sides of the grippers and has a keyway that engages with the gripper shaft. The drive shaft is also engaged with the drive arm. The drive arm has a two-part structure that conforms to the arc surface of the grippers. When the gripper shaft rotates, it drives the drive arm and drive shaft to rotate. The grippers rotate downwards under gravity and upwards under the drive of the drive shaft.

[0007] Furthermore, the keyway of the drive arm and the gripper shaft are keyed together.

[0008] Furthermore, the two halves of the drive arm are detachably connected by fasteners for easy installation and disassembly.

[0009] Furthermore, the gripper and the gripper shaft are connected by a shaft hole.

[0010] Furthermore, the drive shaft and the drive arm are connected by a clearance fit through a shaft hole.

[0011] Furthermore, the inner side of the drive arm fits snugly against the arc surface of the gripper.

[0012] Furthermore, there is no cut between the stretching base and the gripper.

[0013] Compared with the prior art, the advantages of this utility model are as follows: by replacing the cylindrical key connection with the drive shaft, the problem of the gripper sagging due to the wear of the cylindrical key is fundamentally solved, the service life of the gripper mechanism is increased, the cut between the gripper and the stretching base is eliminated, potential safety hazards are reduced, and the safety of operation is improved. In addition, the drive arm adopts a two-half structure, which is convenient for disassembly and installation, and easy for maintenance and replacement. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] In some embodiments, please refer to the accompanying drawings. Figures 1-2 A novel gripper mechanism for an aluminum profile stretching machine includes a stretching machine base 1, a gripper shaft 3, grippers 2, a drive arm 4, and a drive shaft 5. The main feature of this embodiment is that the movement of grippers 2 is effectively controlled by the drive arm 4 and the drive shaft 5, which solves the problems of wear and sagging in existing gripper mechanisms and enhances the stability and lifespan of grippers 2.

[0021] In some embodiments, such as Figures 1-2 As shown in the preferred embodiment of this utility model, the novel gripper 2 is connected to the gripper shaft 3 through a shaft hole. The gripper shaft 3 serves to fix the gripper 2 and allow it to rotate. A shaft hole is provided on the gripper shaft 3 to precisely match the gripper 2 and ensure that the gripper 2 can rotate stably.

[0022] In some embodiments, such as Figures 1-2 As shown in the preferred embodiment of this utility model, the drive arm 4 is connected to the gripper shaft 3 through its keyway. The function of the drive arm 4 is to drive the gripper 2 to rotate as necessary. The keyway of the drive arm 4 and the key on the gripper shaft 3 are connected and cooperate to effectively transmit rotational power and ensure that the movement of the gripper 2 does not slip or loosen.

[0023] In a preferred embodiment of this utility model, the drive shaft 5 is connected to the drive arm 4 through a clearance fit in the shaft hole, transmits power and realizes the rotation of the drive arm 4. The function of the drive shaft 5 is to drive the drive arm 4 to rotate by rotating, thereby driving the gripper 2 to rotate upward or downward.

[0024] As a preferred embodiment of this utility model, the drive arm 4 is designed as a two-part structure that is detachably connected by fasteners. This design makes the installation and disassembly of the drive arm 4 more convenient, and facilitates the maintenance, cleaning and replacement of the equipment.

[0025] In a preferred embodiment of this utility model, there is no cut between the stretching machine base 1 and the gripper 2. This design eliminates safety hazards and ensures that the operator is not potentially injured by the gripper mechanism during the operation.

[0026] The working principle of this technical solution is as follows:

[0027] When the drive shaft 5 rotates, it engages with the drive arm 4 through the shaft hole clearance, causing the drive arm 4 to rotate. The rotation of the drive arm 4 causes the gripper shaft 3 to rotate, thereby driving the gripper 2 to move. The gripper 2 rotates downward under the action of gravity. At the same time, driven by the drive shaft 5, the gripper 2 can also rotate upward. The gripper 2 can perform clamping and loosening operations in the aluminum profile stretching machine as needed, thereby completing the gripping and placement function of the aluminum profile during the stretching process. Since the drive arm 4 and the gripper shaft 3 are connected by a keyway and a key, the transmission between the drive arm 4 and the gripper shaft 3 is very stable, effectively avoiding the problem of cylindrical key wear and extending the service life. The two halves of the drive arm 4 can be easily disassembled with fasteners, which facilitates the inspection and maintenance of the equipment.

[0028] This technical solution optimizes the gripper mechanism of the aluminum profile stretching machine, improving the stability of the grippers. Through the cooperation of the drive arm 4 and the drive shaft 5, the sagging phenomenon of the gripper 2 caused by wear during operation is avoided, thereby improving working stability. The no-cut design between the gripper 2 and the stretching machine base 1 eliminates potential safety hazards during operation. The two-half split structure of the drive arm 4 makes the assembly, disassembly, and replacement process simpler, saving maintenance time and costs. The precise key connection design reduces wear and increases the durability of the gripper mechanism, especially under high-frequency use, extending the overall service life of the equipment.

[0029] Furthermore, the gripper mechanism of this utility model can also be implemented through different driving methods. For example, the drive shaft 5 can be driven electrically instead of manually to adapt to different application scenarios. In addition, the connection between the drive arm 4 and the gripper shaft 3 can be optimized through other connection forms (such as gear or belt drive) to achieve higher working efficiency and longer service life.

[0030] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
