Description

Technical Field

[0001] This utility model relates to the field of robotic arms, and in particular to a quick-release structure for the actuator end of a robotic arm. Background Technology

[0002] The quick-release structure of the robotic arm actuator is a key design in the fields of industrial automation and robotics. Its core objective is to achieve rapid, safe, and precise connection and separation of actuators (such as grippers, welding guns, spray heads, etc.) and the robotic arm end effector.

[0003] However, in existing manual robotic arm actuator quick-release structures, once the locking mechanism is opened, the quick-release lower seat will directly separate from the quick-release upper seat, which can easily lead to the risk of the quick-release lower seat falling off accidentally during the disassembly process.

[0004] Therefore, it is essential to invent a quick-release structure for the actuator end of a robotic arm. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a quick-release structure for the actuator end of a robotic arm, which includes a quick-release upper seat, a locking seat, a locking structure, a quick-release lower seat, and a locking block. The quick-release upper seat has a detachable locking seat, and two locking structures are fixedly installed on the quick-release upper seat, evenly distributed at both ends of the block. The quick-release lower seat has a detachable locking block corresponding to the locking seat, which is inserted into the locking seat and positioned between the two locking structures.

[0006] The surface of the quick-release upper seat is evenly provided with several upper mounting holes;

[0007] The surface of the quick-release lower seat is evenly perforated with several lower mounting holes;

[0008] The locking structure includes an open hollow seat, a stop block, and a compression spring. The open hollow seat is fixedly installed on the quick-release upper seat, and the stop block is elastically and slidably installed in the open hollow seat through at least one compression spring.

[0009] The card holder is located between two blocks.

[0010] The quick-release upper seat and quick-release lower seat each have a mounting cavity and two threaded holes on their surfaces. The two threaded holes are located in the corresponding mounting cavities, which are located between the two stops. The card holder is detachably installed in the mounting cavity of the quick-release upper seat, and the card block is detachably installed in the mounting cavity of the quick-release lower seat.

[0011] The card holder and the card block each have countersunk holes that correspond to the wire holes.

[0012] The stop block has notches at both ends, and a rotating roller is rotatably installed in each notch. A portion of the rotating roller protrudes from the notch, and the rotating roller makes rolling contact with the stop block.

[0013] Fasteners are fixedly installed between the countersunk hole and the corresponding threaded hole.

[0014] Compared with the prior art, the advantages of this utility model are:

[0015] The overall design of this utility model not only facilitates the quick replacement of components at the actuator end of the robotic arm, but also prevents the quick-release lower seat from separating directly from the quick-release upper seat when the locking structure is opened and disassembled, thereby avoiding the risk of the quick-release lower seat accidentally falling off and greatly improving the overall safety and reliability.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] Example

[0027] Reference Figure 1-5 A quick-release structure for the actuator of a robotic arm includes a quick-release upper seat 1, a latch 2, a locking structure 3, a quick-release lower seat 4, and a latch 5. The quick-release upper seat 1 is detachably and fixedly equipped with the latch 2. Two locking structures 3 are fixedly installed on the quick-release upper seat 1 and are evenly distributed at both ends of the stop block 32. The quick-release lower seat 4 is detachably and fixedly equipped with a latch 5 corresponding to the latch 2. The latch 5 is inserted into the latch 2 and is located between the two locking structures 3 so that the latch 5 is firmly fixed in the latch 2 by the two locking structures 3.

[0028] Specifically, the card holder 2 adopts a T-slot card holder; the card block 5 adopts a T-shaped card block; so that the card block 5 and the card holder 2 can be assembled together, making the quick-release upper seat 1 and quick-release lower seat 4 more stable;

[0029] Specifically, the surface of the quick-release upper seat 1 is evenly provided with several upper mounting holes 6 so that the quick-release upper seat 1 can be fixedly connected to the robotic arm execution end through the upper mounting holes 6 and the corresponding fasteners.

[0030] Specifically, the surface of the quick-release lower seat 4 is evenly provided with several lower mounting holes 7 so that the quick-release lower seat 4 can be fixedly connected to the required actuator through the lower mounting holes 7 with the corresponding fasteners;

[0031] Specifically, the locking structure 3 includes an open hollow seat 31, a stop block 32, and a compression spring 33. The open hollow seat 31 is fixedly installed on the quick-release upper seat 1 so as to provide a hidden space for the stop block 32 through the open hollow seat 31. The stop block 32 is elastically and slidably installed in the open hollow seat 31 through at least one compression spring 33. The compression spring 33 is set so as to apply pressure to the stop block 32 to compress the compression spring 33, so that the stop block 32 enters the open hollow seat 31. When the stop block 32 loses external pressure, the stop block 32 automatically resets and blocks both ends of the card seat 2.

[0032] Specifically, the card holder 2 is located between the two stops 32.

[0033] Specifically, the surfaces of the quick-release upper seat 1 and the quick-release lower seat 4 each have an installation cavity 8 and two threaded holes 9. The two threaded holes 9 are located in the corresponding installation cavity 8 so that the card holder 2 can be positioned and installed through the installation cavity 8 and the two threaded holes 9. The installation cavity 8 is located between the two stops 32. The card holder 2 can be detachably installed in the installation cavity 8 of the quick-release upper seat 1, and the card block 5 can be detachably installed in the installation cavity 8 of the quick-release lower seat 4.

[0034] Specifically, countersunk holes 10 corresponding to the wire holes 9 are provided through the card holder 2 and the card block 5, so as to provide the required hidden space for the fastener 11 through the countersunk holes 10.

[0035] Specifically, each end of the stop block 32 has a notch 34, and a rotating roller 35 is rotatably installed in each notch 34. Part of the rotating roller 35 protrudes from the notch 34, and the rotating roller 35 makes rolling contact with the locking block 5 so as to prevent wear between the locking block 5 and the stop block 32 during the process of disassembling and assembling the quick-release lower seat 4.

[0036] Specifically, a fastener 11 is fixedly installed between the countersunk hole 10 and the corresponding threaded hole 9. The fastener 11 is a bolt, which makes it convenient to replace the card holder 2 or card block 5 separately when the card holder 2 or card block 5 is worn later.

[0037] In this embodiment, when installing the quick-release lower seat 4, the stop block 32 is pressed into the interior of one of the open hollow seats 31, so that the stop block 32 retracts into the interior of the open hollow seat 31. First, one end of the locking block 5 of the quick-release lower seat 4 is inserted into the locking seat 2 from one end of the locking seat 2. At this time, the stop block 32 is released. Due to the locking block 5, pressure will continue to be applied to the stop block 32, still forcing the stop block 32 to remain inside the open hollow seat 31, until the locking block 5 is fully inserted into the locking seat 2. The stop block 32 automatically resets under the action of the compression spring 33, thereby blocking the locking block 5 and preventing the locking block 5 from coming out of the locking seat 2.

[0038] When it is necessary to disassemble the quick-release lower seat 4 later, press the stop block 32 into the interior of one of the open hollow seats 31. At this time, the quick-release lower seat 4 will not automatically separate from the quick-release upper seat 1. You need to pull the quick-release lower seat 4 to one side of the stop block 32 until the locking block 5 comes out of the locking seat 2. In this way, the risk of the quick-release lower seat 4 falling off accidentally is avoided when replacing the quick-release lower seat 4.

[0039] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
