Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, and in particular to a magnetic suction robot gripping device. Background Technology

[0002] Currently, the industry generally uses manual loading and unloading for workpiece machining. This means that workers use handling equipment to feed workpieces into or out of the machine tool one by one and manually clamp or release them. Production efficiency is greatly affected by manual labor and safety risks are significantly increased.

[0003] In existing technologies, there are also robotic arm structures that can grasp workpieces and thus grip parts. However, existing gripping robotic arms require adjustment of the gripper when gripping parts of different sizes to accommodate different sizes of parts. This increases the workload of adjusting the robotic arm and is difficult to do.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0019] See Figure 1 , Figure 2 and Figure 5 This utility model provides a magnetic suction robot gripping device, which includes: a fixed housing 2, which has a magnetic component 3 inside. By installing and fixing the fixed housing 2 to a predetermined position of the robot, the magnetic component 3 can attract parts and ensure subsequent clamping of the parts. A guide component 4 is slidably provided inside the magnetic component 3, and the guide component 4 passes through the magnetic component 3. In use, the parts are attracted to and pressed against the guide component 4, thereby driving the gripper 1 to clamp the side of the parts. In the initial state, the bottom of the guide component 4 extends out of the magnetic component 3, which facilitates subsequent contact with the parts and drives the guide component 4 to move to the top. The top of the guide component 4 is provided with... A guide section 42 drives the gripper 1 to rotate and clamp the component. At least three grippers 1 are rotatably connected to the outer wall of the fixed housing 2. Each gripper 1 is equipped with a torsion spring, which provides the opening force for the gripper 1. The top of the gripper 1 is provided with an abutment part 11, which abuts against the guide section 42. When the guide member 4 moves upward, the guide section 42 pushes the abutment part 11 to expand outward, and at the same time pushes the gripping part 13 at the bottom of the gripper 1 to rotate inward, thereby clamping the component. A mounting hole 21 is provided inside the fixed housing 2. A mounting part 22 is provided at the bottom of the mounting hole 21. The magnetic component is installed inside the fixed housing 2 through the mounting part 22 and the mounting hole 21.

[0020] In one exemplary implementation, see Figure 2 The magnetic component 3 is an electromagnetic coil, which is installed and fixedly connected inside the fixed housing 2. A power supply mechanism (existing technology, not described in detail) is provided outside the electromagnetic coil. The power supply mechanism is connected to the electromagnetic coil through a wire. A base is provided inside the electromagnetic coil, and the electromagnetic coil is sleeved on the base. When the electromagnetic coil is energized, the base and the electromagnetic coil generate a magnetic field, thereby making the base magnetic, which can effectively attract the parts.

[0021] In one embodiment, to ensure the sliding and triggering effect of the guide 4, a sliding hole is provided inside the magnetic component 3. The guide 4 is slidably connected to the inside of the sliding hole, ensuring that the guide 4 can slide inside the sliding hole, thereby facilitating the adjustment of the position of the guide 4 and further controlling the angle of the gripper 1 to clamp the component. A thrust spring 43 is sleeved on the outside of the guide 4. Under the action of the thrust spring 43, the guide 4 extends out of the bottom of the sliding hole. The thrust spring 43 ensures the reset force of the guide 4. A force-receiving head 44 is provided at the bottom of the guide 4. The force-receiving head 44 extends out of the sliding hole, and the bottom of the force-receiving head 44 abuts against the top of the component, ensuring that when the component is forcefully attracted to the bottom of the fixed housing 2, the component can press the force-receiving head 44 and press the thrust spring 43, thereby triggering the gripper 1 to grasp the component through the attraction force.

[0022] Furthermore, in order to ensure that the movement of the guide 4 drives the gripper 1 to grasp effectively, the guide part 42 is a beveled structure. The position of the guide part 42 corresponds to the position of the gripper 1. The abutment part 11 abuts against the beveled structure to ensure that the beveled structure slides up and down. The abutment part 11 can rotate, thereby ensuring that the gripper 1 can be driven to rotate along the rotation axis 12, so as to grasp the parts through the gripper part 13. The top of the beveled structure is provided with an upper limit part 41. When the abutment part 11 abuts against the upper limit part 41, the gripper 1 is in the open state. At this time, the gripper 1 can abut against the limit part 41 under the action of the torsion spring, which makes it easier to release the parts.

[0023] Better yet, to ensure the proper installation of gripper 1, combined with Figure 2 , Figure 3 and Figure 4 The fixed housing 2 has a hinge seat 23 on its outside. The gripper 1 is rotatably connected to the hinge seat 23. The gripper 1 rotates on the hinge seat 23 to clamp the parts. The gripper 1 includes: a rotating shaft 12 rotatably connected to the hinge seat 23. The rotating shaft 12 is located in the middle section of the gripper 1. A torsion spring is provided between the rotating shaft 12 and the hinge seat 23. The torsion spring provides the restoring force of the gripper 1 and the opening force of the gripper 1. The gripping part 13 is located at the bottom of the rotating shaft 12. The gripping part 13 grips the parts. The abutting part 11 is a force-bearing column that abuts against the guide part 42. This ensures that the force-bearing column can be rotated by moving up and down through the inclined structure, thereby driving the gripping part 13 to grip the parts.

[0024] When using, see Figures 1-5The component to be clamped and grasped is a metal component that can be attracted. When clamping is required, the fixed housing 2 is moved to the bottom until the component enters the gripping part 13. Then, the power supply mechanism supplies power to the electromagnetic coil. At this time, the base generates magnetism and magnetically attracts the component. The component is pressed by the force and the guide 4 slides upward. Then, the guide 42 pushes the abutment 11 to expand outward, which drives the gripping part 13 to clamp the side of the component, thereby achieving the clamping and fixing effect. When the size of the component changes, the gripping part 13 clamps the component to complete the fixation, thereby achieving fixation for different sizes.

[0025] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
