Description

Technical Field

[0001] This utility model relates to the field of machine tool gantry technology, and in particular to a machine tool gantry robot. Background Technology

[0002] In the field of machine tool processing, gantry robots are key equipment for automated material handling, and their gripping stability and adaptability directly affect production efficiency and material safety.

[0003] Patent document CN222471682U discloses a machine tool gantry robot. This device includes a main body, a mounting plate fixedly connected to one side of the main body, a protective shell fixedly connected to one side of the main body, a connecting block fixedly connected to one side of the protective shell, a motor fixedly connected to one side of the connecting block, and a base plate fixedly connected to the output shaft of the motor via a coupling. A fixing plate is fixedly connected to one side of the base plate. This invention facilitates the user's installation and use of the robot by providing multiple mounting openings around the main body. This allows for efficient installation and use of the robot. The motor, when activated by the user, drives its output shaft to rotate via the base plate fixedly connected to the coupling, enabling efficient clamping of objects held by the gripping blocks.

[0004] However, the clamping structures in the aforementioned comparative documents employ a rigid clamping method, lacking buffer adjustment capability. When the clamping force is not properly controlled (e.g., too large or too small), it can easily lead to surface damage and deformation of the material, or cause material displacement or falling due to insecure clamping, especially posing a higher risk when handling irregularly shaped or precision components. Therefore, we provide a machine tool gantry robot. Utility Model Content

[0024] 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.

[0025] The robotic gripper structure in the prior art uses rigid clamping, lacking buffering and adjustment capabilities, which can easily lead to material damage. This embodiment provides a machine tool gantry robotic arm that can reduce the pressure of the gripping components on the object, reduce damage or displacement, improve stability, adapt to objects of different shapes, and enhance flexibility and applicability. Please refer to... Figure 1 - Figure 5 The machine tool gantry robot includes multiple symmetrically distributed gripping claws 1. The upper and lower inner sides of the gripping claws 1 have toothed structures. The toothed structures can increase the friction between the gripping claws 1 and the gripped items, preventing the items from slipping due to vibration, tilting, etc. during gripping and movement. Especially for materials with relatively smooth surfaces, it can significantly improve the stability of gripping. In addition, the inner side of the gripping claws 1 is arc-shaped, which allows the gripping claws 1 to better fit items with curved surfaces or irregular shapes, increasing the contact area, making the gripping more uniform, and avoiding excessive local pressure that could cause deformation or damage to the items.

[0026] The clamping structure in the comparison document is a rigid clamp without a buffer adjustment function. If the clamping force is not properly controlled, whether it is too large or too small, it can easily cause damage and deformation to the material surface. It may also cause the material to shift or fall due to unstable clamping. The risk is even higher for the handling of irregularly shaped parts and precision components. In order to solve the above problems... A buffer groove 2 is formed in the middle of the inner side of the gripper 1. The volume of the buffer groove 2 is larger than that of the abutment 4. When the gripper 1 grips an item, the item exerts pressure on the abutment 4, which compresses the buffer spring 5 and moves into the buffer groove 2. Because the buffer groove 2 is larger, it can accommodate the displacement of the abutment 4, ensuring that the buffer structure can function properly. The extension and contraction of the spring offsets part of the gripping pressure, preventing damage to the item due to excessive force. It also adapts to the gripping needs of items of different sizes. Multiple sets of sliding grooves 3 are formed on both sides of the gripper 1, penetrating the buffer groove 2. The sliding grooves 3 are symmetrically distributed on both sides of the gripper 1. The symmetrically distributed sliding grooves 3 guide the movement of the abutment 4, ensuring that the abutment 4 slides smoothly along the sliding grooves 3 when under force, avoiding deviation or jamming, and ensuring the stability of the buffering process. The buffer groove 2 is equipped with an abutment 4 that slides in conjunction with the sliding groove 3 to ensure... To ensure stable movement of the item, the abutment 4 is an arc-shaped silicone structure. The arc design better conforms to the surface of the clamped item, especially suitable for items with arc or irregular shapes. It increases the contact area to distribute pressure and avoid excessive local force that could damage the item. The silicone material has a certain degree of elasticity and softness, which can further buffer the impact force during clamping and increase the friction between the abutment and the item to prevent the item from slipping. At the same time, it avoids scratches or indentations on the surface of the item, protecting precision parts or fragile materials. There are multiple sets of buffer springs 5 ​​connected between the abutment 4 and the inside of the buffer groove 2 to reduce the pressure of the item on the gripper 1. There are four sets of buffer springs 5. The multiple sets of springs working together can provide more buffer margin to adapt to the clamping needs of items of different weights and hardnesses, further reducing the pressure of the item on the gripper 1 and improving the stability during the clamping and movement process.

[0027] Two sets of linkage rods 6 are rotatably connected to the top of the gripper 1. A fixed plate base 7 is rotatably connected to the top of the two sets of linkage rods 6. The fixed plate base 7 is fixed to the mounting base 8 by multiple sets of screws, enhancing the stability of the connection between the fixed plate base 7 and the mounting base 8. This ensures that the two will not loosen or shift relative to each other during the operation of the robot (such as when gripping or moving materials), providing a stable support foundation for the gripper 1 and other structures below. The top of the fixed plate base 7 is fixed to the mounting base 8, and the top of the mounting base 8 is connected to the moving structure of the machine tool gantry. An asynchronous motor 9 is mounted on the mounting base 8, and the output shaft of the asynchronous motor 9... A lead screw 10 is installed on the upper part of the mounting base 8, and a baffle is installed at the bottom of the lead screw 10 to prevent the cross seat 11 from detaching from its outer surface. The baffle can prevent the cross seat 11 from detaching from the bottom of the lead screw 10 due to excessive movement, ensuring that the cross seat 11 always maintains a threaded connection with the lead screw 10, ensuring the normal operation of the linkage structure, avoiding the failure of the robot gripping function due to the cross seat 11 detaching, and ensuring the safety and reliability of the equipment operation. The lead screw 10 is threadedly connected to the cross seat 11, and the four sides of the cross seat 11 are rotatably connected to the linkage rod 6 near the lead screw 10 through the connecting plate 12.

[0028] The mounting base 8 is connected to the moving structure of the machine tool gantry to provide a mounting foundation for the whole. When the asynchronous motor 9 is working, it drives the lead screw 10 on the output shaft to rotate. The rotation of the lead screw 10 drives the cross seat 11, which is threaded to it, to move up and down along the axis of the lead screw 10. The cross seat 11 is connected to the linkage rod 6 through the connecting plate 12. The movement of the cross seat 11 will drive the two sets of linkage rods 6 to rotate. The bottom end of the linkage rod 6 is rotatably connected to the gripper 1, and the top end is rotatably connected to the fixed plate base 7. Therefore, the rotation of the linkage rod 6 will drive the gripper 1 to open and close to complete the operation of gripping or releasing the item.

[0029] When gripping an item, the item contacts the abutment 4 on the inner side of the gripper 1. The abutment 4 is an arc-shaped silicone structure. It is subjected to the pressure of the item and moves into the buffer groove 2 along the sliding grooves 3 on both sides of the gripper 1. At the same time, it compresses the buffer spring 5 between the abutment 4 and the buffer groove 2. The elasticity of the buffer spring 5 can reduce the pressure of the item on the gripper 1. Furthermore, the toothed structure on the upper and lower sides of the inner side of the gripper 1 and the arc-shaped design on the inner side can enhance the gripping friction and the fit to items of different shapes, ensuring the stable movement of the item. The baffle at the bottom of the lead screw 10 can prevent the cross seat 11 from disengaging from the lead screw 10, ensuring the stability and reliability of the overall structure operation.
