Description

Technical Field

[0001] This utility model relates to the field of mechanical automation technology, specifically to a mechanical gripper for transporting brake drums. Background Technology

[0002] Brake drums achieve vehicle deceleration through friction, balancing economy, durability, and parking safety. However, due to limitations in heat dissipation, they are mostly used on rear wheels or in commercial vehicles. Modern passenger cars are gradually replacing them with front disc and rear drum brakes or full disc brakes, but drum brakes still hold a place in low-cost scenarios. Most transfer devices on the market include a motion mechanism and a clamping mechanism. The moving end of the motion mechanism is connected to the clamping mechanism and is used to drive the clamping mechanism to move back and forth between two production lines. The clamping mechanism is used to clamp the brake drum during the movement.

[0003] However, in existing technologies, because brake drums have a certain weight, and the clamping mechanism can only clamp the side wall of the brake drum at a single point, this clamping method is unreliable. During the transfer of the brake drum, the brake drum often falls off the clamping mechanism, resulting in transfer failure and posing a significant safety hazard to subsequent operations. In addition, the clamping mechanism cannot rotate, making it impossible to change the direction of the brake drum during the transfer of the transport route. Traditional gripper transport methods are difficult to achieve precise control of the equipment, affecting the accuracy and effectiveness of the transfer and transport work. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes a mechanical gripper for transporting brake drums, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] A mechanical gripper for transporting brake drums includes a clamping mechanism comprising two symmetrically distributed pneumatic grippers capable of moving in the same direction. Each pneumatic gripper has multiple gripping fingers, whose outer surfaces tightly engage with the inner surface of the brake drum during transport. A rotating mechanism includes a servo motor, a reducer, a hollow rotating platform, and a support plate. The servo motor, reducer, and hollow rotating platform are all mounted on the support plate. The servo motor and reducer rotate coaxially, and the reducer drives the hollow rotating platform to rotate. The clamping mechanism is located below the support plate. Through precise control of a solenoid valve and collaborative innovation in modular design, the mechanical gripper solves the technical bottlenecks of traditional gripping devices in terms of clamping stability, maintenance complexity, and functional expandability, significantly improving the efficiency and safety of brake drum transport.

[0007] Furthermore, the pneumatic gripper has an openable and closable structure and is used to grip the transport brake drum.

[0008] Furthermore, the pneumatic gripper is provided with several mounting positions, and the gripping fingers are located on the mounting positions.

[0009] Furthermore, the finger clip is provided with several stepped protruding copper blocks, which are used to prevent the finger clip 12 from being damaged during transportation.

[0010] Furthermore, the clamping mechanism is distributed along an axis perpendicular to the brake drum.

[0011] Furthermore, the mechanical gripper also includes a solenoid valve, which controls the opening and closing of the gripper.

[0012] Furthermore, the mechanical gripper adopts a modular design, with the clamping and rotating mechanisms being detachable and replaceable independently, facilitating maintenance and functional expansion.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. In practical use, this utility model solves the problems of unstable clamping, easy damage to workpieces, and complex maintenance in traditional brake drum transportation by innovatively combining a precision clamping mechanism, high-precision rotation control, modular design, and anti-slip and wear-resistant structure. It not only significantly improves transportation efficiency and safety but also reduces the total life-cycle cost of the equipment through modular design, providing an efficient and reliable gripping solution for automated production lines in the automotive manufacturing and heavy machinery industries.

[0015] 2. In practical use, the rotating mechanism of this utility model adopts a combination of servo motor, reducer and hollow rotating platform to achieve precise angle adjustment of brake drum, meet the needs of complex assembly line for workpiece posture adjustment. The clamping mechanism and rotating mechanism adopt modular design, and the pneumatic gripper and servo motor can be disassembled and replaced independently to reduce maintenance costs.

[0016] 3. In practical use, the high transmission efficiency of the servo motor and reducer, combined with the pneumatic drive of the gripper, reduces overall energy consumption and heat loss. The stepped protruding copper blocks on the gripper fingers enhance the friction between the gripping surface and the brake drum. The elastic deformation of the copper blocks also absorbs the impact force during transportation, preventing wear or breakage of the gripper fingers. The composite structure of the gripper fingers and copper blocks, through material selection and stepped distribution, disperses stress and extends service life. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-2 As shown, according to an embodiment of the present invention, a mechanical gripper for transporting a brake drum is provided, including a clamping mechanism 1, comprising two symmetrically distributed pneumatic grippers 11 that can move in the same direction. Each pneumatic gripper 11 is provided with multiple gripping fingers 12. During transport, the outer side of the gripping fingers 12 is tightly engaged with the inner side of the brake drum. The pneumatic grippers 11 are openable and closable structures. The pneumatic grippers 11 are used to grip and transport the brake drum. The pneumatic grippers 11 are provided with several mounting positions 13. The gripping fingers 12 are located on the mounting positions 13. The gripping fingers 12 are provided with several stepped protruding copper blocks 14. The copper blocks 14 are used to prevent the gripping fingers 12 from being damaged during transport. The clamping mechanism 1 is distributed along an axis perpendicular to the brake drum.

[0024] The rotating mechanism 2 includes a servo motor 21, a reducer 22, a hollow rotating platform 23, and a support plate 24. The servo motor 21, reducer 22, and hollow rotating platform 23 are all mounted on the support plate 24. The servo motor 21 and reducer 22 rotate coaxially. The reducer 22 drives the hollow rotating platform 23 to rotate. The clamping mechanism 1 is located below the support plate 24. The servo motor 21 achieves precise speed and torque output through the coaxially connected reducer 22. The reduction ratio can be adjusted according to requirements to ensure the rotation angle control accuracy of the hollow rotating platform 23 and meet the requirements for workpiece posture adjustment during brake drum transportation.

[0025] The mechanical gripper also includes a solenoid valve 15, which controls the opening and closing of the pneumatic gripper 11. The solenoid valve 15 controls the opening and closing of the pneumatic gripper 11 through air pressure, so as to achieve precise adjustment of the clamping force, adapt to the clamping requirements of brake drums of different materials, and avoid workpiece deformation or surface damage due to excessive clamping.

[0026] The mechanical gripper adopts a modular design, with the clamping mechanism 1 and rotating mechanism 2 being detachable and replaceable independently, facilitating maintenance and functional expansion. The modules are connected via standardized interfaces, supporting quick replacement of clamping components of different specifications to adapt to various workpiece types.

[0027] In summary, by utilizing the above-mentioned technical solution of this utility model, in practical use, this utility model, through the clamping mechanism 1 and the rotating mechanism 2, can not only achieve stable transportation of the brake drum by the mechanical gripper, but also rotate its direction. This solves the problem in the prior art where the brake drum often falls off the clamping mechanism during the transfer process, leading to brake drum transfer failure and posing a significant safety hazard to subsequent brake drum operations. Furthermore, the clamping mechanism cannot rotate, making it impossible to change the direction of the brake drum during the transfer of the transportation route. Traditional gripper transportation methods are difficult to achieve precise control of the equipment, affecting the accuracy and effectiveness of the transfer and transportation work.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
