[0002] With the continuous development of the manufacturing industry, improving production efficiency and reducing labor costs have become key focuses for enterprises. With technological advancements and increased automation, the application of automation and intelligent technologies, especially in machine tool loading and unloading processes, has become crucial for enterprise transformation and upgrading.

[0003] Modern manufacturing demands increasingly higher precision and stability from its products. Automated grippers for machine tool loading and unloading, through precise control systems and advanced clamping technology, can meet the needs of high-precision production, reduce error rates, and improve product quality. In the traditional machine tool unloading industry, the automated loading and unloading of circular gear parts typically employs pneumatic fingers to grip individual workpieces. This often requires replacing the gripper with different specifications or adjusting equipment parameters, which not only increases operational difficulty and cost but also reduces production efficiency. Furthermore, due to the diversity of circular gears, the compatibility of automated gripper equipment often becomes a significant factor restricting enterprise development.

[0004] With the continuous development and improvement of automation technology, automatic loading and unloading technology for machine tools is also constantly innovating and progressing. Therefore, this utility model proposes an automatic loading and unloading gripper device for machine tools, thereby bringing greater convenience and benefits to industrial production.

A fixing plate 16 is located on the top of the servo motor 4. A linear guide rail 15 is located on the top of the fixing plate 16. A shift fork 14 is located on the top of the linear guide rail 15. A spindle 18 is located on the top of the shift fork 14. A protective cover 9 is located on the right side of the robot flange 1. A ball screw 10 is located behind the protective cover 9.

A support-side bearing seat 13 is located behind the shift fork connecting plate 12. A gear workpiece 20 is located on the outer edge of the robot flange 1.

[0021] This embodiment adopts a V-shaped double claw structure design, which facilitates coordinated loading and unloading and improves work efficiency.

[0022] The main mechanical structure of the gripper in this embodiment consists of a robot flange 1, a loading base plate 2, a unloading base plate 3, a fixing plate 16, and a side plate 17. The above parts are fixed together by bolts, pins, stops, etc., forming the main components of the gripper's mechanical structure, which bear the force during the gripper's operation and maintain the stability of the structure.

[0023] The transmission mechanism in this embodiment is symmetrically arranged on the loading base plate 2 and the unloading base plate 3, and consists of a servo motor 4, a motor mounting plate 5, a synchronous pulley drive 6, a synchronous belt 7, a synchronous pulley driven 8, a ball screw 10, a fixed side bearing seat 11, and a support side bearing seat 13. The servo motor 4 drives the synchronous pulley drive 6 to rotate, and the synchronous belt 7 drives the synchronous pulley driven 8 to rotate, thereby driving the ball screw 10 to rotate. The ball screw nut seat of the ball screw 10 is connected to the shift fork connecting plate 12 to realize the linear motion function of the shift fork 14.

[0024] In this embodiment, the shift fork 14 is mounted on the shift fork connecting plate 12.

[0026] Working principle: When the device starts working, the operator places the group of workpieces on the tray (the tray has a vertical spindle). The robot moves the gripper to a fixed position. The gripper spindle is coaxial with the workpiece spindle on the tray. At the same time, the shift fork 14 moves to the clamping zero point. The servo motor 4 drives the ball screw 10 to rotate and drive the shift fork 14 to move. The shift fork 14 moves the group of workpieces along the direction of the gripper spindle and clamps the group of workpieces to the fixed side of the spindle, realizing the group of workpiece gripping function. The servo motor 4 reverses to realize the group of workpiece unloading function.

[0027] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0028] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
