[0034] The present invention will now be described in further detail with reference to the accompanying drawings.
[0035] like Figure 1-3 As shown, this utility model discloses a modular tool quick-change structure, comprising:
[0036] Fixed components, connected to the robot;
[0037] The fixed bracket 1 is connected to the fixed component and has two symmetrically arranged clamping arms 2, wherein the clamping arms 2 are provided with limit components;
[0038] The quick-change tool 3 has limiting grooves 31 on both sides that cooperate with the limiting components.
[0039] The advantage of adopting the above technical solution is that it enables quick tool changes without the need for complex external drive devices. The tool change operation can be completed solely through the cooperation of the mechanical structure, which greatly simplifies the quick change process and improves work efficiency.
[0040] In some implementation schemes, such as Figure 4-5 As shown, the limiting assembly includes limiting strips 21 symmetrically arranged inside the clamping arm 2. Limiting strips 21 are fitted with limiting beads 22 and springs. A limiting hole 23, which mates with the limiting beads 22, is provided in the limiting groove 31. The spring and limiting beads 22 are a ball spring structure. The spring is installed inside the clamping arm 2, and the ball can extend and retract under the action of the spring. When the quick-change tool 3 is inserted, it compresses the steel ball on the ball spring, causing the steel ball to retract inside the limiting strip 21. When the quick-change tool 3 is in position, the steel ball is aligned with the limiting hole 23 on the quick-change tool 3, and the steel ball pops out. The elasticity of the ball spring can prevent the quick-change tool 3 from disengaging under normal vibration or pushing force. However, the robotic arm 7 can overcome the elasticity of the ball spring and disengage the quick-change tool 3.
[0041] There are two clamping arms 2, arranged in parallel, with one end forming an opening and the other end connected by a connecting part. The overall shape is U-shaped. The quick-change tool 3 enters into the U-shape for fixation. A fixed limit pin 24 is also provided between the clamping arms 2. The quick-change tool 3 is provided with a corresponding limit hole 2. When the quick-change tool 3 slides into place along the limit strip 21, the limit pin 24 is inserted into the limit hole 2, abutting against the quick-change tool 3 and preventing the quick-change tool 3 from sliding, thus achieving the function of limiting.
[0042] In some implementations, the fixed bracket 1 also includes a connecting plate 11 and a sliding plate 5. The connecting plate 11 is fixedly connected to the sliding plate 5 and the clamping arm 2. The sliding plate 5 is slidably connected to the fixed component. The shape of the connecting plate 11 is set according to the usage requirements and extends outward from the robot body so that the quick-change tool 3 will not collide with the robot.
[0043] Furthermore, the fixing components include: a fixed guide rail 4, which is fixedly mounted on the robot and is a universal guide rail. When the placement position of the quick-change tool 3 needs to be changed, only the installation position of the fixed guide rail 4 needs to be changed. The bottom of the sliding plate 5 is provided with a sliding groove 51, the inside of which contacts the top of the fixed guide rail 4 and slides along the fixed guide rail 4. The sliding groove 51 is provided with a protrusion 52, which is set along the length direction of the sliding plate 5 and cooperates with the fixed guide rail 4 for limiting. A slide rail fixing seat 53 is also provided on the sliding plate 5. The slide rail fixing seat 53 is located on the other side of the sliding plate 5 away from the protrusion 52 and cooperates with the protrusion 52 to clamp the fixed guide rail 4, so that the sliding plate 5 slides on the fixed guide rail 4. At the same time, the slide rail fixing seat 53 is also provided with The device includes a threaded pin 54 and a fixing nut 55. The threaded pin 54 can be a square threaded pin, with a threaded rod at its tail that connects to the fixing nut 55. The sliding plate 5 and the slide rail fixing seat 53 are provided with through holes for the threaded pin 54 to pass through. The shape of the through hole can match the shape of the threaded pin 54. The tail of the threaded pin 54 passes through the slide rail fixing seat 53 and is fixed by the fixing nut 55. The fixing nut 55 is a hand-tightening nut that can be manually rotated. Tightening the fixing nut 55 clamps the fixing guide rail 4 in the slide rail fixing seat 53, fixing the position of the sliding plate 5 and preventing the fixing bracket 1 from moving. Loosening the nut allows the fixing bracket 1 to move along the fixing guide rail 4, enabling the fixing bracket 1 to change its position. This allows for manual and quick installation and docking without the need for tools.
[0044] In some implementations, a lifting ring 56 is mounted on the sliding plate 5. The lifting ring 56 is provided to facilitate lifting operations of the robot during transportation and commissioning.
[0045] In some implementations, a handle 57 is mounted on the sliding plate 5, and the handle is secured by screws.
[0046] This utility model also discloses a robot, such as Figure 6 As shown, it includes a main body, a walking component 6, and a robotic arm 7. It also includes the modular tool quick-change structure described in the above technical solution. The walking component 6 includes leg components or walking wheel sets, etc., to realize the walking function of the main body. The robotic arm 7 is equipped with a quick-change joint to realize quick-change tool 3 grasping. The tool can be different tools depending on the application scenario. For example, in the sanitation scenario, it can be a gripper tool, a blowing tool, a vacuuming tool, a wiping tool, etc., and in the kitchen scenario, it can be a shovel, a spoon, etc.
[0047] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
