[0016] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.
[0017] Please see Figures 1 to 2 This utility model provides a high-precision gripper release device, comprising two sets of gripper seats 2 symmetrically arranged on the lower side of a gripper base 1. The two sets of gripper seats 2 are rotatably connected to the gripper base 1. A gripper gear 3 is provided at the connection point between the gripper seats 2 and the gripper base 1. A rotation drive 5 is mounted on the upper side of the gripper base 1. A gripper rack 4 is provided at the movable end of the rotation drive 5, extending to the lower side of the gripper base 1. The gripper rack 4 and the gripper gear 3 are connected by a gear and rack meshing connection. When a workpiece needs to be gripped, the rotation drive 5 drives the rack to... The upward movement causes the two sets of gripper gears 3 to rotate inwards, and the two sets of gripper seats 2 to move closer to each other, thereby clamping the workpiece. When it is necessary to release the workpiece, the rotating drive 5 drives the rack to move downwards, thereby causing the two sets of gripper gears 3 to rotate outwards, and the two sets of gripper seats 2 to move away from each other, thereby releasing the workpiece and achieving the release effect. The extension and retraction movement of the gripper rack 4 drives the clamping or releasing action of the two sets of grippers, which can achieve the synchronization of the movement of the two sets of grippers, thereby reducing the possibility of workpiece tilting or displacement deviation after release.
[0018] Two sets of rotating bases 6 are symmetrically arranged on the lower side of the gripper base 1. The two sets of gripper seats 2 are rotatably connected to the corresponding rotating bases 6. The rotating bases 6 are U-shaped rotating bases. The gripper seats 2 are located inside the open end of the rotating bases 6. The rotating bases 6 support and limit the rotation of the two sets of gripper seats 2. The U-shaped rotating bases 6 can prevent displacement in other directions during the rotation of the gripper seats 2, thereby further improving the stability of the gripping or releasing action of the gripper seats 2. The outer diameter of the gripper base 1 extends out of the rotating base 6, which facilitates the meshing of the gripper gear 3 and the gripper rack 4 on the gripper base 1, and improves the connection stability between the gripper gear 3 and the gripper rack 4.
[0019] The gripper rack 4 is symmetrically arranged on both sides of the movable end of the gripper drive 9, which can improve the gear rack meshing stability between the gripper rack 4 and the gripper gear 3. When the rotating drive 5 drives the gripper rack 4 to extend and retract, it can stably drive the gripper gear 3 to rotate around the gripper base 1.
[0020] Limiting plates 7 are symmetrically arranged on both sides of the gripper base 1. The limiting plates 7 are located at the end of the movement trajectory of the gripper base 2. When the rotating drive 5 drives the gripper rack 4 to move downward until the gripper base 2 opens to the maximum angle, the limiting plates 7 can play a limiting support role for the gripper base 2, preventing the gripper base 2 from overstepping and improving the operating stability of the equipment. In addition, a buffer pad is provided on the limiting plate 7 near the gripper base 2 to avoid damage to the gripper base 2.
[0021] The gripper base 2 is provided with a gripper platform 8. The gripper platform 8 extends out of the gripper base 2 away from the gripper base 1. The gripper platform 8 can provide a more sufficient gripping working surface for clamping, thereby meeting the clamping processing of workpieces of different models.
[0022] The gripper platform 8 is equipped with a detachable gripper drive 9. The movable end of the gripper drive 9 is equipped with a clamping part 10. The clamping drive can adjust the extension range of the clamping part 10, so that different clamping distances can be used according to different workpieces to ensure a stable clamping effect for different workpieces.
[0023] A scale 11 is provided on the side of the gripper platform 8, and a displacement groove 12 is provided inside the gripper platform 8. The gripper drive component 9 is connected to the displacement groove 12 by bolts. The displacement groove 12 is set along the length direction of the gripper platform 8. By adjusting the position of the gripper drive component 9 on the gripper platform 8, the size of the gripping working surface can be adjusted. Furthermore, the setting of the displacement groove 12 can meet the position adjustment of the gripper drive component 9 with a larger stroke.
[0024] The gripper drive 9 is a single drive unit that drives the gripper rack 4 to extend and retract, which ensures the stability of the gripper rack 4. The gripper rack 4 and the gripper gear 3 are connected by a gear and rack meshing, which can improve the synchronization of the movement of the two sets of gripper gears 3. In this way, when releasing the workpiece, the situation of workpiece tilting or displacement deviation can be reduced.
[0025] When a workpiece needs to be clamped, this invention rotates the drive unit, causing the rack to move upwards. This causes the two sets of gripper gears to rotate inwards, bringing the two sets of gripper seats closer together, thus clamping the workpiece. When the workpiece needs to be released, the drive unit rotates the rack downwards, causing the two sets of gripper gears to rotate outwards, moving the two sets of gripper seats away from each other, thus releasing the workpiece. The extension and retraction of the gripper rack drives the clamping and releasing actions of the two sets of grippers, achieving synchronization of their movements and reducing the likelihood of workpiece tilting or displacement after release. Therefore, this invention effectively overcomes the shortcomings of existing technologies and has high industrial application value.
[0026] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
