Description

Technical Field

[0001] This utility model belongs to the field of mechanical claw technology, and in particular relates to a retractable mechanical claw structure for robots. Background Technology

[0002] Robotic grippers are important components of industrial robots that are similar to human hands, used to grasp and manipulate objects. They are usually installed at the end of the robot and are widely used in automated production and manufacturing processes. Robots can use grippers to hold and move workpieces, tools or other objects, and with the development and progress of technology, robotic grippers are playing an increasingly important role in industrial manufacturing.

[0003] However, existing robotic grippers have a maximum limit on the travel distance of the robotic arm during application. If the item to be gripped exceeds the maximum travel distance, the gripper needs to be replaced, which affects the normal operation of production. In addition, the gripper's gripping and placing flexibility is limited, and there are technical problems that prevent the precise and stable extension and retraction adjustment of the gripper to make it more flexible and improve its applicability. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a retractable mechanical claw structure for robots, which can effectively solve the problems of the existing technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a retractable mechanical gripper structure for robots, comprising a positioning base and a movable base inserted inside one side of the positioning base, and further comprising:

[0007] An isolation cover is located at the middle position on one side of the top of the positioning seat. A servo motor is provided at the front end of the isolation cover. A shaft is rotatably connected at the middle position between the two ends inside the isolation cover. A transmission gear is provided at the middle position outside the shaft.

[0008] The movable rack is fixedly connected to the top of the movable base;

[0009] The clamping mechanism is located on one side of the movable base;

[0010] The stabilizing structure is located between the middle of one side of the positioning seat and the bottom of the moving seat.

[0011] Furthermore, the front end of the shaft is connected to the output end of the servo motor through the front end of the isolation cover via a bearing, and the moving rack meshes with the transmission gear.

[0012] Furthermore, the clamping mechanism includes a cylinder, a gripper, a hinge rod, and a moving block. The cylinder passes through one side of the interior of the moving seat, and the moving block is provided at the output end of the cylinder. The gripper is movably hinged at the middle position of one side of both ends of the moving seat, and the hinge rod is movably hinged to one side inside the gripper.

[0013] Furthermore, the grippers are symmetrically arranged on the outside of the movable seat, and one end of the hinge rod and one end of the movable block are movably hinged.

[0014] Furthermore, the stabilizing structure includes a limiting groove, a stabilizing slide, and a limiting plate. The limiting groove is located at the middle position on one side of the bottom end inside the positioning seat, the stabilizing slide is located at the bottom end of the movable seat, and the limiting plate is located on one side outside the movable seat.

[0015] Furthermore, the stabilizing slide is fitted into the inner side of the limiting slide groove, and the stabilizing slide can slide inside the limiting slide groove, and the limiting plate is annular.

[0016] This utility model has the following beneficial effects:

[0017] This invention utilizes a servo motor to drive a transmission gear to rotate in both directions, which in turn drives a moving rack to move horizontally back and forth. This, in turn, causes the moving seat to extend and retract on one side of the positioning seat, thereby enabling the mechanical gripper to precisely position and grip items. This solves the problem of excessively long or short travel distances of the robot arm when gripping items, improves the applicability of the mechanical gripper, reduces downtime caused by changing grippers, and increases production efficiency. Simultaneously, a limiting plate confines one side of the moving seat within the positioning seat to prevent the mechanical gripper from slipping out of the positioning seat during extension and retraction adjustments, thus affecting normal use. Furthermore, the moving seat is stabilized by relatively sliding limiting grooves and stabilizing slides during movement, ensuring the stability of the mechanical gripper during movement and further guaranteeing the stability of the mechanical gripper in gripping and picking up items.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please see Figure 1-4 As shown, this utility model is a retractable mechanical gripper structure for robots, including a positioning base 1 and a movable base 3 inserted inside one side of the positioning base 1, and further including:

[0027] A clamping mechanism is provided on one side of the movable seat 3. The clamping mechanism includes a cylinder 5, a gripper 4, a hinge rod 13, and a moving block 14. The cylinder 5 is installed inside the movable seat 3 on one side. The output end of the cylinder 5 is provided with the moving block 14. The cylinder 5 can drive the moving block 14 to move back and forth. The gripper 4 is movably hinged at the middle position of one side of both ends of the movable seat 3. The gripper 4 is symmetrically arranged on the outside of the movable seat 3. The hinge rod 13 is movably hinged on one side of the inside of the gripper 4. One end of the hinge rod 13 is movably hinged to one end of the moving block 14. When the cylinder 5 drives the moving block 14 to move back and forth, the gripper 4 hinged to both ends of the movable seat 3 can be driven to open and close through the hinge rod 13. The gripping and picking up of items can be achieved by the gripper 4 being driven to open and close.

[0028] The isolation cover 2 is located at the middle position on one side of the top of the positioning seat 1. A servo motor 6 is provided at the front end of the isolation cover 2. A shaft 9 is rotatably connected at the middle position between the two ends inside the isolation cover 2. The front end of the shaft 9 is connected to the output end of the servo motor 6 through the front end of the isolation cover 2 via a bearing. A transmission gear 8 is provided at the middle position outside the shaft 9. The shaft 9 is driven to rotate inside the isolation cover 2 by the servo motor 6, which in turn drives the transmission gear 8 outside to rotate. A movable rack 11 is fixedly connected to the top of the movable seat 3. The movable rack 11 meshes with the transmission gear 8. When the transmission gear 8 rotates, it drives the movable rack 11 that meshes with it to move, thereby driving the movable seat 3 to move in and out of the telescopic direction.

[0029] When in use, the servo motor 6 set at the front end of the isolation cover 2 is started to drive the shaft 9 connected to its output end to rotate between the two ends inside the isolation cover 2. When the shaft 9 rotates, it drives the transmission gear 8 set on its outside to rotate in both directions, thereby driving the moving rack 11 set on the top of the moving seat 3 and meshing with it to move back and forth, thereby driving the moving seat 3 and the mechanical claw structure set inside to extend and retract, so as to flexibly and accurately clamp and pick up items.

[0030] A stabilizing structure is provided between the middle position of one side of the positioning seat 1 and the bottom of the movable seat 3. The stabilizing structure includes a limiting groove 10, a stabilizing slide 12 and a limiting plate 7. The limiting groove 10 is provided at the middle position of one side of the bottom end of the positioning seat 1. The stabilizing slide 12 is provided at the bottom end of the movable seat 3. The stabilizing slide 12 is embedded in the inner side of the limiting groove 10 and can slide inside the limiting groove 10. The limiting groove 10 and the stabilizing slide 12 cooperate with each other to limit and stabilize the movable seat 3 when it moves. The limiting plate 7 is provided on one side of the outside of the movable seat 3 and is annular. The limiting plate 7 can be used to limit one side of the movable seat 3 inside the positioning seat 1.

[0031] During use, as the movable seat 3 is moved telescopically, the stabilizing slide 12 at its bottom end slides back and forth in the limiting slide groove 10 provided on one side of the bottom end inside the positioning seat 1 to ensure the stability of the movable seat 3 during movement and prevent the movable seat 3 from tilting left or right or turning forward or backward. At the same time, the ring-shaped limiting plate 7 provided on one side of the movable seat 3 limits one side of it to the inside of the positioning seat 1.

[0032] Working principle: When using the mechanical claw structure, the cylinder 5 is activated to drive the moving block 14 to move back and forth. This allows the gripper 4, which is hinged to both ends of the moving seat 3, to open and close, enabling the gripping and placement of items. When the robot arm's travel distance limits the mechanical claw structure, the servo motor 6 is activated to drive the shaft 9 to rotate within the isolation cover 2 and transmit the gear 8 to rotate forward and backward. This causes the moving rack 11 to move back and forth, which in turn causes the moving seat 3 and the mechanical claw structure to extend and retract. At the same time, the stabilizing slide 12 slides back and forth within the limited slide groove 10, preventing the moving seat 3 from tilting left and right or deflecting forward and backward. This allows for stable extension and retraction adjustment of the mechanical claw structure position for flexible and precise gripping and placement of items.

[0033] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
