Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, and in particular to a robotic arm that is easy to assemble. Background Technology

[0002] A robotic arm is an automated operating device that can mimic certain movements and functions of a human hand and arm to grasp, move objects, or operate tools according to a fixed program. Some robotic arms are used to clamp workpieces, thereby enabling rapid handling of processed workpieces. These robotic arms are equipped with clamping jaws for clamping workpieces.

[0003] However, when clamping workpieces of different shapes from different batches, it is often necessary to change the clamping jaws of the robot arm to match the workpieces to be clamped. However, most existing clamping jaws are fixed by multiple fixed parts, which requires operators to spend a lot of time on disassembly and installation when changing them, resulting in low installation and replacement efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a robotic arm that is easy to assemble.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A robotic arm that is easy to assemble includes a robotic arm unit, the robotic arm unit being assembled with the robotic arm unit, the robotic arm unit including a robotic arm body, the robotic arm body including symmetrically movable gripper mounting blocks on the front side, and each gripper mounting block having a clamping gripper mechanism inserted and installed on its front side;

[0007] The chuck mounting block has a mounting slot for mounting the clamping chuck mechanism. A through hole communicating with the mounting slot is formed on one side wall surface of the chuck mounting block. A mounting hole is formed on one side wall surface of the chuck mounting block on the side of the through hole. A limit mechanism is installed at the mounting hole.

[0008] Furthermore, in a preferred configuration, the clamping claw mechanism includes a limiting block, which is installed at the mounting slot.

[0009] In addition, a preferred structure is that a protrusion is provided on one side surface of the clamping claw mechanism, and a clamping ring is provided on the other side surface of the clamping claw mechanism away from the protrusion.

[0010] In addition, a preferred structure is that multiple rubber strips are evenly arranged on the inner wall of the clamping ring, and the clamping claw mechanism has a limit insertion hole on the side wall with the protrusion.

[0011] Furthermore, in a preferred configuration, the limiting mechanism includes a mounting frame, which is installed at the mounting hole. A retractable telescopic connecting rod is movably mounted on the mounting frame, and a limiting insert is fixedly connected to the end of the telescopic rod on the side away from the mounting frame.

[0012] Furthermore, in a preferred configuration, the limiting rod is used to pass through the through hole and enter the limiting insertion hole, and a protruding plate is provided on the outer wall of the limiting rod.

[0013] In addition, a preferred structure is that a spring is sleeved on the outside of the telescopic connecting rod, with one end of the spring fixedly connected to the mounting bracket and the other end fixedly connected to the limiting plug.

[0014] The beneficial effects of this utility model are as follows: By setting the claw mounting block, the clamping claw mechanism is made detachable, and the clamping claw mechanism can be quickly assembled by plugging and unplugging. With the setting of the limiting mechanism, the efficiency is higher and the assembly time is faster when installing or disassembling the clamping claw mechanism. There is no need to disassemble too many fixed parts, which makes the clamping claw mechanism of the robot body easy to assemble and shortens the time for replacing and installing the clamping claw mechanism.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-8 A manipulator that is easy to assemble includes a robotic arm unit 01, a robotic arm unit 02 assembled on the robotic arm unit 01, and a robotic arm unit 02 including a robotic arm body 1. The robotic arm body 1 includes symmetrically movable claw mounting blocks 2 on the front side. Each claw mounting block 2 has a clamping claw mechanism 3 inserted into its front side. The claw mounting blocks 2 have mounting slots 21 for mounting the clamping claw mechanisms 3. One side wall surface of the claw mounting blocks 2 has a through hole 23 communicating with the mounting slot 21. One side wall surface of the claw mounting blocks 2, located on the side of the through hole 23, has a mounting hole 22. A limiting mechanism 4 is installed at the mounting hole 22. The claw mounting blocks 2, in conjunction with the limiting mechanism 4, facilitate the quick replacement of the clamping claw mechanisms 3.

[0026] The clamping claw mechanism 3 includes a limiting insert 34, which is installed in the mounting slot 21. A protrusion 31 is provided on one side of the clamping claw mechanism 3, and a clamping ring 32 is provided on the other side of the clamping claw mechanism 3 away from the protrusion 31. The limiting insert 34 is used to be clamped in the mounting slot 21.

[0027] Furthermore, multiple rubber strips 321 are evenly arranged on the inner wall of the clamping ring 32, and the clamping claw mechanism 3 has a limit hole 33 on the side wall where the protrusion 31 is provided. The limit hole 33 facilitates the restriction of the limit mechanism 4.

[0028] Meanwhile, the limiting mechanism 4 includes a mounting frame 41, which is installed at the mounting hole 22. A telescopic connecting rod 42 is movably mounted on the mounting frame 41. A limiting rod 44 is fixedly connected to the end of the telescopic rod on the other side away from the mounting frame 41. The limiting rod 44 is used to pass through the through hole 23 and enter the limiting insertion hole 33. A protrusion 45 is provided on the outer wall of the limiting rod 44. The protrusion 45 facilitates the operator to lift the limiting rod 44.

[0029] In addition, a spring 43 is sleeved on the outside of the telescopic connecting rod 42. One end of the spring 43 is fixedly connected to the mounting bracket 41, and the other end is fixedly connected to the limiting plug 44. The spring 43 is used to realize the reset of the telescopic connecting rod 42.

[0030] In this embodiment, when the manipulator body 1 needs to replace the clamping claw mechanism 3 used for clamping the workpiece, it first oscillates the convex plate 45 to lift the limiting rod 44, causing the telescopic connecting rod 42 to retract, the spring 43 to be compressed, and the limiting rod 44 to disengage from the limiting insertion hole 33 and the through hole 23, so that the limiting block 34 is no longer stuck by the limiting rod 44. The limiting block 34 can be pulled out from the mounting slot 21, thereby quickly removing the clamping claw mechanism 3. Then, the clamping claw mechanism 3 with a clamping ring 32 of a different shape is replaced. The rubber strip 321 on the inner side of the clamping ring 32 is used to increase the friction with the workpiece.

[0031] During installation, simply insert the limiting plug 34 into the mounting slot 21, then release the raised protrusion 45. The spring 43 releases its elastic potential energy, causing the telescopic connecting rod 42 to extend and reset. The limiting plug 44 is then reinserted into the limiting plug hole 33, quickly locking the installed clamping claw mechanism 3.

[0032] In this utility model, the clamping claw mechanism 3 is made detachable by the set claw mounting block 2, and the clamping claw mechanism 3 can be quickly assembled by plugging and unplugging. With the setting of the limiting mechanism 4, the efficiency is higher and the assembly time is faster when installing or disassembling the clamping claw mechanism 3, without the need to disassemble too many fixed parts, making the clamping claw mechanism 3 of the robot body 1 easy to assemble and shortening the time for replacing and installing the clamping claw mechanism 3.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
