Description

Technical Field

[0001] This utility model relates to the field of mechanical gripper technology, and in particular to a novel universal three-stage transmission arm hook structure. Background Technology

[0002] Mechanical grippers are widely used in industrial robots. A mechanical gripper is a mechanical clamping structure, typically designed and manufactured according to specific requirements. Most grippers on the market use hydraulic pressure and springs to clamp or release items. They are tools used to pick up or release objects. Currently, in the production field, grippers consist of a motor and a clamp. The clamp and motor are connected; the motor's movement drives the clamp to pick up or release items, making operation simple.

[0003] In existing technologies, rotary grippers typically use a gripper cylinder in conjunction with a rotary cylinder to achieve gripping and rotation, or a motor structure in conjunction with a gripper structure to achieve gripping and rotation. Adding rotation functionality to existing rotary grippers requires rotating the entire gripper, which is not only structurally complex and space-consuming, but also requires a high-power motor and consumes a lot of energy. Therefore, there is a need to develop a gripper with a simple structure, small footprint, and low energy consumption, suitable for use in confined spaces. Utility Model Content

[0004] The purpose of this invention is to solve the technical problems of existing rotary grippers that require the entire gripper to rotate to add a rotation function, which is not only complex in structure and large in space, but also requires a high-power motor and consumes a lot of energy. The invention provides a new type of universal three-stage transmission arm hook structure to solve the above technical problems.

[0005] A novel universal three-stage transmission arm hook structure is characterized by comprising a driver, an A transmission arm, a B transmission arm, a rotating hook, a rotating shaft, a support cantilever, a support base, a connecting frame, a base, and a mounting base. The base is fixedly mounted above the mounting base. One end of the support cantilever is fixedly mounted on one side of the base, and the other end has an arc-shaped groove. The support base is assembled on the end of the support cantilever near the base. The driver is fixed on the support base. The output end of the driver is rotatably connected to one end of the A transmission arm via the connecting frame and the rotating shaft. The other end of the A transmission arm is rotatably connected to the support cantilever via the rotating shaft. The A transmission arm has an A square groove, and the B transmission arm has a B square groove. The B transmission arm is rotatably mounted in the A square groove via the rotating shaft. The rotating hook has a connecting protrusion. The rotating hook is inserted into the B square groove via the connecting protrusion and is rotatably connected to the B transmission shaft via the rotating shaft. A protective cover is assembled on the support cantilever, and the A transmission arm, B transmission arm, and driver are located inside the protective cover.

[0006] Furthermore, the actuator is an electric cylinder or a pneumatic cylinder.

[0007] Furthermore, a bushing or bearing is mounted on the outside of the rotating shaft.

[0008] Furthermore, the mounting base is provided with mounting through holes.

[0009] Compared with the prior art, the advantages of this utility model include: This utility model forms a three-stage linkage structure through the setting of a support cantilever, A transmission arm, B transmission arm and rotating hook. This design structure is simple, greatly saves installation space, and can achieve precise gripping. The three-stage linkage structure can complete the gripping action without overall rotation, occupying little space and can be used in narrow spaces. The drive can be an electric cylinder or a pneumatic cylinder, with a wide range of choices and strong versatility. Bushings or bearings can be set on the outside of the rotating shaft to maintain smooth rotation and reduce energy consumption. Attached Figure Description
