Description

Technical Field

[0001] This utility model relates to the technical field of grinding wheel mesh production equipment, and more specifically, to a gripper mechanism for docking grinding wheel mesh. Background Technology

[0002] During the production of grinding wheels, the grinding wheels often need to be stacked on the guide rod. Between different production processes, the grinding wheel screens need to be transferred to the guide rod frequently. Currently, the transfer of grinding wheel screens mainly relies on vacuum suction cups or mechanical grippers. Regardless of the transfer method, the center hole of the grinding wheel screen needs to be aligned with the guide rod. Then, the vacuum suction cup or mechanical gripper lowers the grinding wheel screen, and the grinding wheel screen falls down. The center hole of the grinding wheel screen eventually fits onto the guide rod. During this process, if the grinding wheel screen is not in a horizontal position when it falls onto the guide rod, it is easy for the center hole of the grinding wheel screen to become misaligned with the guide rod, causing the grinding wheel screen to fall to the outside of the guide rod. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a gripper mechanism for mating grinding wheels and mesh sheets.

[0004] To achieve the above objectives, this utility model provides a gripper mechanism for connecting abrasive wheel mesh, which is used to transfer abrasive wheel mesh to a connecting rod. Its structure includes a base, and its innovation lies in the following: a connecting rod extends vertically downward from the base, and two openable and closing support arms are provided on the side of the connecting rod. The opening between the two support arms is oriented upward and centered on the connecting rod. The interior of the connecting rod is a hollow cavity, and the cavity is provided with a telescopic gripper that pushes the two support arms to open and close.

[0005] The top of the connecting rod has a locating groove, and the bottom of the connecting rod extends downward with a locating rod. When the locating rod is inserted into the locating groove, the telescopic gripper of the connecting rod drives the two support arms to perform a closing motion.

[0006] Furthermore, the side of the aforementioned connecting rod is provided with two vertical grooves, and two support arms are correspondingly arranged inside the vertical grooves. When the two support arms perform a closing movement, the two support arms are engaged into the two vertical grooves one by one.

[0007] Furthermore, the aforementioned linkage telescopic gripper includes a cylinder and two connecting rods disposed inside the cavity. The output end of the cylinder is disposed downwards, and a connecting block is provided at the output end of the cylinder. The two ends of the connecting block are provided with symmetrical first hinge shafts. A second hinge shaft is provided at the connection between the bottom of the support arm and the inside of the vertical groove. The two connecting rods are correspondingly connected to the first hinge shaft and the second hinge shaft.

[0008] Furthermore, the rising positioning rod is elastically positioned at the bottom of the docking rod, and a pressure sensor is installed inside the positioning groove. The telescopic gripper of the connecting rod is equipped with a controller, and the pressure sensor and the controller are electrically connected.

[0009] Furthermore, the bottom of the aforementioned docking rod is provided with a receiving cavity, and the positioning rod is movably disposed inside the receiving cavity. The bottom of the positioning rod extends below the receiving cavity, and a buffer spring is provided inside the receiving cavity. The top of the positioning rod is connected to the buffer spring.

[0010] Furthermore, the length of the aforementioned receiving cavity plus the length of the positioning groove is greater than the length of the positioning rod, and the extension length of the positioning rod below the receiving cavity is greater than the length of the positioning groove.

[0011] The technical effects and advantages of this utility model are as follows: This utility model aligns the positioning rod on the docking rod with the positioning groove on the string rod. The positioning rod moves into the interior of the positioning groove. At this time, the rod telescopic gripper drives the two support arms to perform a closing movement, so that the two support arms are in a closed state on the docking rod. The grinding wheel mesh extends from the docking rod and slides into the string rod, thereby realizing the precise transfer of the grinding wheel mesh to the string rod. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0015] like Figures 1 to 2 In one specific embodiment of this utility model, it is applied to transfer the grinding wheel mesh to the connecting rod 1. Its structure includes a base 11, a connecting rod 12 extending vertically downward on the base 11, two openable and closing support arms 13 on the side of the connecting rod 12, the opening between the two support arms 13 is arranged facing upward and with the connecting rod 12 as the center line, the inside of the connecting rod 12 is a hollow cavity 14, and the cavity 14 is provided with a connecting rod telescopic gripper 2 that pushes the two support arms 13 to open and close.

[0016] The top of the connecting rod 1 has a positioning groove 15, and the bottom of the connecting rod 12 extends downward with a positioning rod 16. When the positioning rod 16 is inserted into the positioning groove 15, the connecting rod telescopic gripper 2 drives the two support arms 13 to perform a closing motion.

[0017] In this invention, the process of transferring the abrasive wheel mesh to the connecting rod 1 is as follows: The connecting rod 12 is first aligned with the placed abrasive wheel mesh. At this time, the connecting rod telescopic gripper 2 drives the two support arms 13 to be in a closed state. After the connecting rod 12 enters the center hole of the abrasive wheel mesh, the connecting rod telescopic gripper 2 drives the two support arms 13 to be in an open state. The two support arms 13 support the abrasive wheel mesh on the connecting rod 12. Then, the positioning rod 16 on the connecting rod 12 is aligned with the positioning groove 15 on the connecting rod 1. The positioning rod 16 moves into the interior of the positioning groove 15. At this time, the telescopic gripper drives the two support arms 13 to perform a closing movement, so that the two support arms 13 are in a closed state on the connecting rod 12. The abrasive wheel mesh extends the connecting rod 12 and slides into the connecting rod 1, thereby realizing the precise transfer of the abrasive wheel mesh to the connecting rod 1.

[0018] In this utility model, as a preferred embodiment, the side of the connecting rod 12 is provided with two vertical grooves 3, and two support arms 13 are correspondingly arranged inside the vertical grooves 3. When the two support arms 13 perform a closing movement, the two support arms 13 are inserted into the two vertical grooves 3 one by one.

[0019] In this invention, the vertical groove 3 is designed so that when the two support arms 13 are in the closed state, they can be completely submerged in the side of the connecting rod 12, thereby allowing the grinding wheel mesh to slide smoothly from the connecting rod 12 onto the string rod 1.

[0020] In this utility model, as a preferred embodiment, the above-mentioned linkage telescopic gripper 2 includes a cylinder 21 and two connecting rods 22 disposed inside the cavity 14. The output end of the cylinder 21 is disposed downward, and a connecting block 4 is provided at the output end of the cylinder 21. The two ends of the connecting block 4 are provided with symmetrical first hinge shafts 41. The bottom of the support arm 13 and the connection point inside the vertical groove 3 are provided with a second hinge shaft 42. The two connecting rods 22 are correspondingly connected to the first hinge shaft 41 and the second hinge shaft 42.

[0021] In this utility model, the linkage telescopic gripper 2 drives the two gripping arms to open and close using the cylinder 21 as the power source. One end of the linkage 22 hinges on the connecting block 4 via the first hinge shaft 41, and the other end of the linkage 22 hinges at the bottom of the support arm 13 via the second hinge shaft 42, thereby driving the opening and closing of the two gripping arms.

[0022] In this utility model, as a preferred embodiment, the rising positioning rod 16 is set at the bottom of the docking rod 12 with elastic up-and-down movement, the positioning groove 15 is provided with a pressure sensor, the connecting rod telescopic gripper 2 is provided with a controller, and the pressure sensor and the controller are electrically connected.

[0023] In this utility model, when the positioning rod 16 is inserted into the positioning groove 15, the positioning rod 16 presses against the inside of the positioning groove 15 and performs elastic movement. The pressure sensor detects the downward pressure of the positioning rod 16. When the pressure remains stable, it indicates that the docking rod 12 and the connecting rod 1 have been stably docked. At this time, the pressure sensor transmits the signal to the controller, and the controller opens the telescopic clamp 2, thereby driving the two clamping arms to perform a closing movement, accurately grasping the control timing of the telescopic clamp 2.

[0024] In this utility model, as a preferred embodiment, the bottom of the docking rod 12 is provided with a receiving cavity 5, and the positioning rod 16 is movably disposed inside the receiving cavity 5. The bottom of the positioning rod 16 extends below the receiving cavity 5, and a buffer spring 51 is provided inside the receiving cavity 5. The top of the positioning rod 16 is connected to the buffer spring 51.

[0025] In this invention, the up-and-down elastic movement of the positioning rod 16 is achieved by the buffer spring 51, thereby realizing elastic movement inside the receiving cavity 5.

[0026] In this utility model, as a preferred embodiment, the length of the receiving cavity 5 plus the length of the positioning groove 15 is greater than the length of the positioning rod 16, and the extension length of the positioning rod 16 below the receiving cavity 5 is greater than the length of the positioning groove 15.

[0027] In this utility model, when the positioning rod 16 is inserted into the positioning groove 15, the positioning rod 16 can be completely submerged between the receiving cavity 5 and the positioning groove 15, so that the bottom of the connecting rod 12 and the top of the connecting rod 1 can abut and connect, making it easy for the connecting rod 1 to slide smoothly onto the connecting rod 1.
