Description

Technical Field

[0001] This utility model relates to the field of automated robotic arm processing and assembly technology for parts, and in particular to a telescopic outer diameter gripper mechanism. Background Technology

[0002] In the process of parts production or assembly, in some special cases, it is desirable to use automated equipment for loading and unloading, especially when multi-station processing is performed on a single machine tool. However, due to space constraints, ordinary gripper structures cannot meet the processing efficiency requirements, or the structure of robotic arms is limited.

[0003] To address the shortcomings of existing technologies, a telescopic outer diameter gripper mechanism needs to be designed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a telescopic outer diameter gripper mechanism.

[0005] A telescopic outer diameter gripper mechanism includes a mounting base, two sliders, two connecting plates, two connecting rods, and two grippers. A bidirectional translational power device is mounted on the mounting base. Two parallel balance grooves are formed at the bottom of the mounting base. The two sliders are located at opposite ends of the bottom. Each slider includes a base that is U-shaped, with a balance gripper protruding from one side of its top opening. The base is fixed to the connecting plate at its bottom. The protrusion and balance gripper on one side of the base opening are both located within the balance grooves. The base is mounted on the bidirectional translational power device, allowing the protrusion on one side of the base opening and the balance gripper on the other side to slide within the balance grooves. The two connecting rods are cross-mounted via a connecting shaft. One end of each connecting rod is rotatably connected to the connecting plate via the connecting shaft, and the grippers are fixed to the other end of the connecting rods. A limit protrusion is provided on the end of the balance gripper furthest from the base.

[0006] Furthermore, the bidirectional translational power device can employ two cylinders, respectively located at both ends of the mounting base, with their output ends facing each other, and the base installed at the output ends of the cylinders.

[0007] Furthermore, the bidirectional translational power device can use two motors, which are respectively set at both ends of the mounting base and their output ends are opposite each other. The output ends of the motors are equipped with lead screws, and the base is mounted on the lead screws.

[0008] Furthermore, a limiting stepped groove is formed in the balance groove, and the limiting protrusion is located in the limiting stepped groove and slides within it.

[0009] Furthermore, the length of the limiting stepped groove corresponds to the moving path of the limiting protrusion on the balance claw.

[0010] Furthermore, the gripper is provided with an anti-slip pad on the side that contacts the workpiece, and toothed anti-slip strips are provided at the top and / or bottom positions.

[0011] Furthermore, the bottom of the mounting base is convex.

[0012] Beneficial effects: This utility model uses a slider composed of a base and a balancing claw to ensure the stability of the gripper during the workpiece clamping process. Furthermore, the balancing claw allows the slider to slide in a balancing groove, maintaining balance throughout the clamping process and preventing workpiece slippage. This effectively saves time and space for automatic loading and unloading robots, improving production efficiency. It also simplifies the structure of the loading and unloading robot, reducing parts processing costs. Moreover, this utility model has a simple structure, low cost, and stable operation. When used in conjunction with automatic loading and unloading assembly machinery, it completes automated production, effectively saving manpower. It is suitable for a wide range of automated production lines for the processing and assembly of toothed parts. Attached Figure Description

[0014] 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. Example 1

[0015] Please refer to Figures 1-7This embodiment proposes a telescopic outer diameter gripper mechanism, including a mounting base 1, two sliders 2, two connecting plates 3, two connecting rods 4, and two grippers 5. A bidirectional translational power device is mounted on the mounting base 1. Two parallel balance grooves 1a are formed at the bottom of the mounting base 1, which is convex in shape. The two sliders 2 are located at opposite ends of the bottom. Each slider 2 includes a base 21, which is concave in shape. A balance gripper 22 is provided on one side of the top opening to ensure the gripper 5 is stable during workpiece clamping. The balance gripper 22 also allows the slider 2 to slide within the balance grooves 1a, maintaining balance throughout the clamping process and preventing workpiece detachment. The bottom of the base 21 is fixed to the connecting plates 3. The protrusion on one side of the base 21 opening and the balance gripper 22 are both located within the balance grooves 1a. Inside, the base 21 is mounted on the translational bidirectional power device, so that the protrusion on one side of the opening of the base 21 and the balance claw 22 on the other side slide in the balance groove 1a. By setting a balance claw 22 on one side, costs are saved and it can also cooperate with the protrusion on one side of the opening to achieve sliding balance, thereby ensuring clamping stability. Two connecting rods 4 are installed crosswise through a connecting shaft. One end of the connecting rod 4 is rotatably connected to the connecting plate 3 through the connecting shaft. The gripper 5 is fixed to the other end of the connecting rod 4. A limit protrusion is set at the end of the balance claw 22 away from the base 21. A limit stepped groove is opened in the balance groove 1a. The limit protrusion is located in the limit stepped groove and slides in it. The length of the limit stepped groove corresponds to the movement path of the limit protrusion on the balance claw 22. The movement path can be set according to the actual situation.

[0016] In this embodiment, the translational bidirectional power device can use two cylinders, which are respectively set at both ends of the mounting base 1, and their output ends are opposite each other. The base 21 is installed on the output end of the cylinder. The installation method of the translational bidirectional power device adopts the existing conventional technology, which will not be described in detail here.

[0017] The gripper 5 is provided with an anti-slip pad on the side that contacts the workpiece, and toothed anti-slip strips are provided at the top and / or bottom to prevent the workpiece from falling off during clamping. The gripper 5 can be configured to adapt the shape of the side that contacts the workpiece to the workpiece according to the actual situation, so as to facilitate clamping. Example 2

[0018] Unlike Embodiment 1, the bidirectional translational power device can use two motors, which are respectively set at both ends of the mounting base 1 and their output ends are opposite each other. The output ends of the motors are equipped with lead screws, and the base 21 is mounted on the lead screws. The installation method of the bidirectional translational power device adopts existing conventional technology, which will not be described in detail here.

[0019] Please refer to Figures 6-7When the bidirectional translational power device moves inward, the angle of the two connecting rods 4 along the connecting shaft continuously decreases, thereby achieving the effect of the gripper 5 extending forward. When the angle reaches the workpiece clamping angle and the workpiece clamping position is reached, the workpiece is clamped. Similarly, when the bidirectional translational power device moves outward, the angle of the two connecting rods 4 along the connecting shaft continuously increases, thereby achieving the effect of the gripper 5 moving backward, avoiding the machine tool processing position, and realizing that the gripper 5 can extend and retract its position while clamping the workpiece. This invention effectively saves time and space for automatic loading and unloading robots, improves production efficiency, simplifies the structure of the robot, saves on parts processing costs, and features a simple structure, low cost, and stable operation. When used in conjunction with automatic loading and unloading assembly machinery, it completes automated production, effectively saving manpower. It is applicable to a wide range of automated production lines for the processing and assembly of toothed parts.

[0020] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
