Description

Technical Field

[0001] The utility model relates to the technical field of transport claws, in particular to a transport claw with a protective structure. Background Art

[0002] The gripper is also called the end effector of the robot arm. It is installed on the robot arm and has the function of gripping, transporting, and placing objects at a certain location. From the perspective of morphology, the gripper can have fingers like a human hand, such as three-finger or five-finger products, or it can be a palm without fingers, such as a parallel two-finger gripper. The gripper used for handling is called a handling gripper.

[0003] The existing carrying claws generally grasp objects by moving two grippers closer and further away from each other. First, the carrying claw moves to the top of the object to be grasped, and then the two grippers move away from each other until the distance between the two grippers is greater than the lateral diameter of the object. The carrying claw then moves downward until the two grippers are located on both sides of the grasped object. The two carrying claws then move closer to each other until the object is clamped, and then the carrying claw carries the object to the location where it is needed.

[0004] Based on the above-mentioned related technologies, the inventor believes that the above-mentioned carrying claw lacks a buffer component for the gripper when in use. In actual use, the gripper may become loose due to inertia or long-term use. The gripper may touch the outer wall or collide with each other during movement. After long-term use, the gripper may be damaged. At the same time, the installation head of the existing gripper is relatively simple and can generally only be adapted to connecting arms of fixed sizes. In actual use, there are still certain deficiencies. Utility Model Content

[0005] In view of the above problems existing in the prior art, the main purpose of the utility model is to provide a transport claw with a protective structure.

[0006] The technical solution of the utility model is as follows: a carrying claw with a protective structure comprises a protective frame, the outer side of the protective frame is fixedly connected to a motor, the interior of the protective frame is rotatably connected to a bidirectional screw rod, one end of the bidirectional screw rod extends to the outer side of the protective frame and is fixedly connected to the output end of the motor, the outer side of the bidirectional screw rod is symmetrically threaded with a clamping hand, a protective component is provided inside the protective frame, a mounting component is provided on the top of the protective frame, the protective component and the mounting component are used in conjunction with each other, the protective component comprises a spring, the spring is sleeved on the outer side of the bidirectional screw rod, one end of the two springs close to each other is fixedly connected to the clamping hand, the other ends of the two springs are fixedly connected to the inner wall of the protective frame, the inner wall of the protective frame is symmetrically fixedly connected to a slide rail, the two clamping hands are slidably connected to the slide rail, and the side of the two slide rails close to each other is fixedly connected with a rubber strip for buffering.

[0007] As a preferred embodiment, the mounting assembly includes a slide groove, which is symmetrically opened on both sides of the top of the protective frame, the inside of the slide groove is slidably connected to a slider, the outside of the slider is symmetrically fixedly connected to a limiting block, the top of the slider is fixedly connected to a threaded rod, the outside of the threaded rod is threadedly connected to a No. 1 nut, the top of the No. 1 nut is provided with a No. 2 nut, and the No. 2 nut is connected to the threaded rod.

[0008] As a preferred implementation, a protective cover is fixedly connected to the outer side of the motor, and heat dissipation holes are equidistantly formed at the bottom of the protective cover.

[0009] As a preferred embodiment, the sides of the two grippers that are close to each other are fixedly connected with protective strips at equal distances, and the protective strips are made of rubber material.

[0010] As a preferred implementation, the slide groove is cross-shaped.

[0011] As a preferred implementation manner, the motor is electrically connected to an external controller.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are that the threaded rod is pulled to make the slider slide inside the slide groove. When the threaded rod slides to the appropriate position, the staff turns the No. 1 nut, and the No. 1 nut moves downward until the No. 1 nut fixes the threaded rod on the top of the protective frame. Then the staff passes the threaded rod through the mounting hole of the mechanical arm, and then uses the No. 2 nut to fix and install it. After the installation is completed, the staff starts the motor, and the output end of the motor drives the bidirectional screw rod to rotate, so that the two grippers move in the direction of approaching each other. Through the set protection component, the rubber strip can buffer the two grippers when they are close to each other to prevent the two grippers from touching each other. When the two grippers move in the direction away from each other, the spring is squeezed by the grippers and generates a rebound force, which can buffer and protect the grippers. Through the set installation component, the carrying claw can adapt to mechanical arms of different installation sizes, which improves the adaptability of the carrying claw. It has a simple structure and strong practicality, and greatly improves the work quality and use efficiency compared with traditional devices. BRIEF DESCRIPTION OF THE DRAWINGS

The two clamps 4 are slidably connected to the slide rail 7, and the side of the two slide rails 7 close to each other is fixedly connected with a rubber strip 6 for buffering. The installation component includes a slide groove 8, and the slide groove 8 is symmetrically arranged on both sides of the top of the protective frame 1. The inside of the slide groove 8 is slidably connected with a slider 9, and the outer side of the slider 9 is symmetrically fixedly connected with a limiting block 10. The top of the slider 9 is fixedly connected with a threaded rod 11, and the outer side of the threaded rod 11 is threadedly connected to a No. 1 nut 12, and the top of the No. 1 nut 12 is provided with a No. 2 nut 13, and the No. 2 nut 13 is connected to the threaded rod 11.

[0023] After the two clamps 4 are moved away from each other, the spring 5 is squeezed by the clamp 4 to generate a rebound force, which can buffer and protect the clamp 4.

[0024] Example 2

[0025] like Figure 1 - Figure 5 As shown, the outer side of the motor 2 is fixedly connected to a protective cover 14, and heat dissipation holes 15 are equidistantly provided at the bottom of the protective cover 14. The two grippers 4 are equidistantly fixedly connected to the sides close to each other with protective strips 16, and the protective strips 16 are made of rubber material. The slide groove 8 is a cross-shaped design, and the motor 2 is electrically connected to an external controller.

[0027] Working principle:

[0028] like Figure 1 - Figure 5As shown, in actual use, the staff first needs to install the carrying claw on the robot arm. First, the staff turns the No. 1 nut 12 to disengage the bottom of the No. 1 nut 12 from the top of the protective frame 1, and then pulls the threaded rod 11 to make the slider 9 slide inside the slide groove 8. When the threaded rod 11 slides to a suitable position, the staff turns the No. 1 nut 12, and the No. 1 nut 12 moves downward until the No. 1 nut 12 fixes the threaded rod 11 on the top of the protective frame 1. Then the staff passes the threaded rod 11 through the mounting hole of the robot arm, and then uses the No. 2 nut 13 to fix it. After the installation is completed, the staff starts Motor 2, the output end of motor 2 drives the bidirectional screw rod 3 to rotate, and then the two clamping hands 4 move towards each other, and the rubber strip 6 can prevent the two clamping hands 4 from touching each other. The rubber strip 6 is set, and the clamping hands 4 can be buffered when they are close to each other. When the two clamping hands 4 move away from each other, the spring 5 is squeezed by the clamping hands 4 and generates a rebound force, which can buffer and protect the clamping hands 4. The slide rail 7 is set to prevent the two clamping hands 4 from shaking during the movement. At this point, the staff has completed the installation and use of the clamping hands 4, which greatly improves the work quality and use efficiency compared with traditional devices.
