DETAILED DESCRIPTION

[0016] 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.

[0017] Example: Figures 1-5 As shown, this utility model provides a quick-release mechanism for a robotic arm end-effector gripper, including a robotic arm body 1. A first mounting block 2 is fixedly installed at the end of the robotic arm body 1. A groove 211 is formed in the middle of the first mounting block 2. A slider 21 is slidably engaged in the middle of the groove 211. Movable blocks 22 are fixedly installed on both sides of the two sliders 21. A first spring 23 is fixedly installed on one side of each of the two movable blocks 22. Two symmetrically distributed cavities 221 are formed in the middle of the first mounting block 2. One end of each of the two first springs 23 is fixedly installed on one side of each cavity 221. The two movable blocks 22 are slidably engaged inside the cavities 221. Two symmetrically distributed first mounting rods 24 are fixedly installed in the middle of the sliders 21. A second mounting block 31 is slidably engaged at the lower part of the first mounting block 2. A clamping device 3 is fixedly installed at the bottom of the second mounting block 31. Two symmetrically distributed second mounting rods 33 are fixedly installed at the top of the second mounting block 31.

[0018] Two symmetrically distributed housings 4 are fixedly installed on the upper side of the first mounting block 2. A limiting rod 41 is slidably engaged in the middle of each housing 4. A second spring 44 is fixedly installed at the lower part of each limiting rod 41. The bottom ends of each second spring 44 are fixedly installed on the lower inner surface of each housing 4. An elastic rod 43 is fixedly installed on the lower side of each limiting rod 41. The upper side of each elastic rod 43 is slidably engaged in the middle side of each housing 4. A push rod 45 is slidably engaged in the middle of one side of each housing 4.

[0019] The lower part of the first mounting block 2 has two symmetrically distributed positioning grooves 321. Positioning blocks 32 are fixedly installed on both sides of the two second mounting blocks 31. The two positioning blocks 32 are slidably locked inside the positioning grooves 321. The positioning grooves 321 and positioning blocks 32 make it easy to install and position the second mounting blocks 31, and at the same time limit the second mounting blocks 31, making the installation of the second mounting blocks 31 more stable.

[0020] The lower part of the first mounting block 2 has two symmetrically distributed second mounting holes 331. The upper parts of the two second mounting rods 33 are slidably locked inside the second mounting holes 331. By setting the second mounting holes 331, the second mounting rods 33 can enter the interior of the groove 211 through the second mounting holes 331.

[0021] The upper portions of the two second mounting rods 33 are each provided with a first mounting hole 241, and the two first mounting rods 24 are each slidingly clamped in the first mounting hole 241. By arranging the first mounting hole 241 and slidingly clamping the first mounting rod 24 in the first mounting hole 241, the second mounting rod 33 can be fixedly positioned.

[0022] The upper portions of the two limiting rods 41 are each fixedly provided with two symmetrically distributed limiting blocks 42, and the four limiting blocks 42 are each slidingly clamped in the upper portion of the shell 4. By arranging the limiting block 42, the limiting rod 41 can be limited to avoid rotation of the limiting rod 41, which causes the elastic rod 43 to be unable to be accurately clamped on one side of the shell 4.

[0023] The middle portions of the two shells 4 are each fixedly provided with a third spring 46, and the middle portions of the two push rods 45 are each fixedly installed on one end of the third spring 46. By arranging the third spring 46, when the push rod 45 pushes the elastic rod 43 out of the middle portion of the shell 4, the push rod 45 is reset under the action of the third spring 46 for reuse.

[0024] The upper portions of the two limiting rods 41 are each slidingly clamped in the inside of the two symmetrically distributed clamping grooves 411 on one side of the upper portion of the sliding block 21. By arranging the clamping groove 411 and slidingly clamping the lower portion of the limiting rod 41 in the inside of the clamping groove 411, the sliding block 21 can be limited to avoid sliding of the sliding block 21 in the inside of the groove 211.

[0025] Working principle: In actual use, the sliding block 21 is pushed towards the groove 211, and the second mounting block 31 is slidingly clamped on the lower portion of the first mounting block 2 after the positioning block 32 is aligned with the positioning groove 321, so that the second mounting rod 33 enters the inside of the groove 211 through the second mounting hole 331. At this time, by loosening the sliding block 21, the sliding block 21 is moved under the action of the first spring 23, and the first mounting rod 24 is inserted into the inside of the first mounting hole 241, so that the second mounting rod 33 can be fixed.

[0026] By pressing the limiting rod 41 downward, the lower portion of the limiting rod 41 is slidingly inserted into the inside of the clamping groove 411, and one end of the elastic rod 43 is slidingly clamped on the middle portion of the shell 4, thereby fixing the limiting rod 41. By clamping the lower portion of the limiting rod 41 in the inside of the clamping groove 411, the sliding block 21 is limited, which avoids movement of the sliding block 21 and causes the limiting of the second mounting rod 33 to be not stable enough, thereby fixing the second mounting block 31 and fixing the clamping device 3.

[0027] When disassembling, the elastic rod 43 is pushed away from the middle part of the shell 4 by pushing the push rod 45, so that the limiting rod 41 is moved upward under the action of the second spring 44 and away from the inside of the clamping groove 411, at this time the sliding block 21 can be pushed to slide in the inside of the groove body 211, so that the first mounting rod 24 is away from the second mounting rod 33, that is, the second mounting block 31 can be detached from the lower part of the first mounting block 2, and then the disassembly work of the clamping device 3 is completed.

[0028] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalent technologies, the present application also intends to include these modifications and variations.
