A magnetic mechanical gripper structure

Abstract

This utility model relates to the field of mechanical gripper technology, specifically to a magnetic mechanical gripper structure. It includes a gripping rod, a mounting base, a positioning block, a cylinder, a rotating pin, an actuating block, a mating pin, a magnet, a U-shaped bonding plate, and connecting components. In use, controlling the cylinder's movement drives the actuating block to rotate, thus changing the working angle of the magnet. When adsorbing a workpiece, first controlling the cylinder's movement drives the actuating block to rotate, allowing the magnet's adsorption plane to rotate to a position where it shares a stepped surface with the U-shaped bonding plate. Then, the U-shaped bonding plate is attached to the workpiece surface. At this point, the magnetic force is optimized and adsorption is achieved through a reasonable gap between the magnet and the workpiece. After adsorption, the workpiece can be moved using the gripping rod. Compared to traditional direct-drive structures, the cylinder structure of this application reduces volume, thereby optimizing equipment size, improving equipment practicality, and increasing the reliability of gripper-workpiece separation.

Description

Technical Field

[0001] This utility model relates to the field of mechanical gripper technology, and in particular to a magnetic mechanical gripper structure. Background Technology

[0002] Magnetic mechanical grippers (also known as magnetic grippers) are mainly used in automated production to handle and grip ferrous workpieces. They achieve precise positioning and rapid handling through electromagnetic adsorption or permanent magnet adsorption, and are widely used in industries such as steel, machinery manufacturing, and logistics warehousing.

[0003] Traditional mechanical grippers that use permanent magnets for adsorption are mostly direct-drive type. That is, the cylinder pushes the magnet to move linearly so that the magnet adheres to the surface of the workpiece for adsorption and then transfer. When detaching, the cylinder drives the magnet to move in the opposite direction so that the magnet detaches from the workpiece surface. However, in this structure, because the magnet needs to overcome the magnetic attraction force when detaching from the workpiece, the cylinder is usually large, which makes the overall structure of the mechanical gripper bulky, inconvenient to use, and impractical. Utility Model Content

[0004] The purpose of this invention is to provide a magnetic mechanical gripper structure that optimizes equipment size, improves equipment usability, and enhances the reliability of gripper separation from workpiece.

[0005] To achieve the above objectives, this utility model provides a magnetic mechanical gripper structure, including a gripping rod, on which a mounting base is mounted via a connecting assembly;

[0006] A positioning block is detachably installed on the mounting base. A cylinder is installed on the positioning block by bolts. An actuating block is installed on the output end of the cylinder by a rotating pin. The actuating block is rotatably installed on the positioning block by a cooperating pin. A magnet is fixedly connected to the actuating block. The magnet is in an inclined state with the end face of the U-shaped bonding plate installed on the positioning block when it is out of the adsorption working position.

[0007] The connecting assembly includes a connecting plate and a connector. The connecting plate is welded to the grip rod and is detachably connected to the mounting base via the connector.

[0008] The two sides of the rotating pin are locked and limited by a circular block and a cotter pin, respectively.

[0009] The mating pin is T-shaped and is limited by the cotter pin.

[0010] A T-shaped spacer is provided between the mating pin and the actuating block, and the mating pin and the T-shaped spacer are slidably connected.

[0011] This utility model discloses a magnetic mechanical gripper structure. During use, controlling the cylinder's movement drives the rotating actuating block, thus changing the working angle of the magnet. When adsorbing a workpiece, the cylinder is first controlled to rotate the actuating block, allowing the magnet's adsorption plane to rotate to a position where it shares a stepped surface with the U-shaped bonding plate. Then, the U-shaped bonding plate is attached to the workpiece surface. At this point, the magnetic force is optimized and adsorption is achieved through a reasonable gap between the magnet and the workpiece. After adsorption, the workpiece can be moved using the gripping rod. Compared to traditional direct-drive structures, the cylinder structure of this application reduces volume, thereby optimizing the equipment's size, improving its practicality, and increasing the reliability of the gripper's separation from the workpiece.

Detailed Implementation

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] like Figures 1 to 3 As shown, where Figure 1 This is a schematic diagram of the overall structure of the magnetic mechanical gripper. Figure 2 This is a structural schematic diagram of mounting base 102. Figure 3This is a schematic diagram of the structure of the actuating block 106. This utility model provides a magnetic mechanical gripper structure: including a gripping rod 101, a mounting base 102, a positioning block 103, a cylinder 104, a rotating pin 105, an actuating block 106, a mating pin 107, a magnet 108, a U-shaped bonding plate 109, and a connecting assembly. The connecting assembly includes a connecting plate 110 and a connecting piece 111. The aforementioned solution optimizes the equipment size, improves its practicality, and enhances the reliability of gripper-workpiece separation. It is understood that the aforementioned solution can optimize the equipment size and improve the reliability of gripper-workpiece separation.

[0019] In this embodiment, the grip rod 101 is used for holding the device. In actual use, a flat plate can be welded onto the grip rod 101, and a button control box connected to a moving cable can be installed on the flat plate by bolts.

[0020] The gripping rod 101 is equipped with a mounting base 102 via a connecting assembly; the mounting base 102 is used for component mounting support.

[0021] A positioning block 103 is detachably mounted on the mounting base 102. A cylinder 104 is bolted to the positioning block 103. An actuating block 106 is mounted on the output end of the cylinder 104 via a rotating pin 105. The actuating block 106 is rotatably mounted on the positioning block 103 via a mating pin 107. A magnet 108 is fixedly connected to the actuating block 106. The magnet 108 is in an inclined state with the end face of the U-shaped bonding plate 109 mounted on the positioning block 103 when it is out of its adsorption working position. The positioning block 103 is fixed to the mounting base 102 by multiple bolts. The cylinder 104 is fixed by multiple bolts and has a through hole at its output end to facilitate the installation of the actuating block 106 via the rotating pin 105. The actuating block 106 is also mounted on the positioning block 103 via the mating pin 107. The magnet 108 is tightened onto the actuating block 106 by a countersunk screw. When the magnet 108 is disengaged from its adsorption working position, its end face is inclined to the U-shaped bonding plate 109 mounted on the positioning block 103. This structure reduces the adsorption area with the workpiece during disengagement, allowing the device to be easily removed with slight force. When the magnet 108 rotates the actuating block 106 to the adsorption position via the cylinder 104, its adsorption surface and the surface of the U-shaped bonding plate 109 that contacts the workpiece form a stepped structure with a certain depth. This structure ensures stable magnetic adsorption while preventing the magnet 108 from contacting the workpiece, thus avoiding damage to the workpiece surface during disengagement and improving the reliability of the gripper's separation from the workpiece. The U-shaped bonding plate 109 is fixed with bolts.

[0022] Secondly, the connecting plate 110 is welded to the gripping rod 101 and is detachably connected to the mounting base 102 via the connector 111. This structure facilitates the connection and fixation of the gripping rod 101 and the mounting base 102, and the connector 111 is a T-shaped screw.

[0023] Then, the two sides of the rotating pin 105 are locked and limited by a circular block 112 and a cotter pin 113, respectively. The circular block 112 can be directly slidably mounted on the rotating pin 105, and then limited by the cotter pin 113, thereby preventing the rotating pin 105 from falling off and ensuring that the actuating block 106 is stably connected to the output end of the cylinder 104.

[0024] Furthermore, the mating pin 107 is T-shaped and is limited by the cotter pin 113.

[0025] Finally, a T-shaped spacer 114 is provided between the mating pin 107 and the actuating block 106, and the mating pin 107 and the T-shaped spacer 114 are slidably connected. The T-shaped spacer 114 passes directly through the through hole on the positioning block 103 and abuts against the actuating block 106. This structure helps to ensure that the actuating block 106 always rotates in the middle position, and then it can be limited by the mating pin 107 and the cotter pin 113 of the T-shaped structure.

[0026] When using this utility model to optimize equipment size and improve equipment usability, the cylinder 104 is controlled to rotate, pushing the actuating block 106 to change the working angle of the magnet 108. When adsorbing a workpiece, the cylinder 104 is first controlled to rotate the actuating block 106, allowing the adsorption plane of the magnet 108 to rotate to a position where it shares a stepped surface with the surface of the U-shaped bonding plate 109. At this point, the adsorption surface and the surface of the U-shaped bonding plate 109 that is in contact with the workpiece form a stepped structure with a certain depth. This structure helps ensure stable magnetic adsorption, while the magnet 108 does not contact the workpiece, avoiding damage to the workpiece surface upon detachment. Then, the U-shaped bonding plate... 109 is attached to the surface of the workpiece. At this time, the magnetic force is optimized and adsorption is achieved through the reasonable gap between the magnet 108 and the workpiece. After adsorption, the workpiece can be moved by the gripping rod 101. The magnet 108 is in an inclined state with the end face of the U-shaped bonding plate 109 installed on the positioning block 103 after it leaves the adsorption working position. The cylinder 104 can be controlled to retract. Then, after the cylinder 104 is fully retracted, the device can be removed with a little force to separate it from the workpiece. Compared with the traditional direct drive structure, the cylinder 104 structure of this application can reduce the volume, thereby optimizing the size of the equipment, improving the practicality of the equipment, and improving the reliability of the separation between the gripper and the workpiece.

Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
