In the tool change process of machine tools, robots play a vital role, they need to accurately grasp and move the tools to achieve efficient automated processing.

[0003] This mechanism utilizes a high-precision positioning and resetting mechanism to ensure the robot accurately places the tool in the desired position and quickly repositions it during tool changes. However, with long-term use, especially when frequently performing tool gripping and movement operations, the gripping area of ​​traditional robots is susceptible to wear, leading to performance degradation. This wear not only affects the robot's gripping accuracy but can also cause the tool to slip. Therefore, a tool change resetting mechanism for machine tools was proposed. Utility Model Content

[0004] In response to the deficiencies in the prior art, the utility model provides a tool changing and resetting mechanism for a machine tool. A detachable anti-skid layer is introduced into the gripping part of the gripping assembly. A magnetic layer is provided on the anti-skid layer, which can generate a magnetic attraction state with the gripping assembly. The anti-skid layer is assembled on the gripping assembly, so that when the gripping part is worn due to long-term use, a new anti-skid layer can be quickly and conveniently replaced. The anti-skid layer has an arc structure that fits the shape of the tool, so that the anti-skid layer can not only effectively prevent the tool from slipping, but also ensure that the manipulator always maintains a high degree of stability and accuracy when gripping the tool.

Example

[0034] See also Figure 1 - Figure 7 A tool changing and resetting mechanism for a machine tool includes a machine tool main frame 1 having a manipulator 101 and a tool magazine 102. A grabbing component 2 is symmetrically connected inside the manipulator 101 for grabbing. An anti-slip layer 3 with an arc-shaped structure 3001 is provided on one side of the grabbing component 2 for stability. The grabbing component 2 and the anti-slip layer 3 are magnetically connected through a magnetic layer 302.

[0035] The tool changing and resetting mechanism of the machine tool of the present application is mainly composed of a main frame 1 of the machine tool, a manipulator 101, a tool magazine 102 and a key grasping component 2. The manipulator 101 and the tool magazine 102 are integrated on the main frame 1 of the machine tool to form a complete tool changing system. Among them, the grasping component 2, as the core part of the mechanism, undertakes the important task of accurately grasping and moving the tool. In order to ensure the stability and accuracy of the tool during the grasping process, an anti-slip layer 3 is specially provided on the grasping surface of the grasping component 2. The anti-slip layer 3 adopts an integrated rubber material design and has an arc structure 3001 that fits the shape of the tool. Its curvature matches the cylindrical radius of the tool and can fit tightly on the surface of the tool, thereby effectively preventing the tool from slipping during the grasping process. The grasping component The main part of 2 is made of rigid metal material to withstand various forces and torques during the grasping process. In order to facilitate subsequent disassembly and assembly operations, a magnetic layer 302 that can produce a magnetic attraction state with the grasping component 2 is designed to assemble the anti-slip layer 3 on the grasping component 2. This design makes it possible to quickly and conveniently replace the new anti-slip layer 3 when the grasping part is worn due to long-term use, thereby extending the service life of the entire tool changing and resetting mechanism. By introducing a removable anti-slip layer 3 in the grasping part of the grasping component 2, it is possible to quickly and conveniently replace the new anti-slip layer 3 when the grasping part is worn due to long-term use. The anti-slip layer 3 can not only effectively prevent the tool from slipping, but also ensure that the manipulator 101 always maintains a high degree of stability and accuracy when grasping the tool.

[0036] Working principle: During the tool changing process, the manipulator 101 first accurately grasps the tool through the grasping component 2 and the anti-slip layer 3. Then, the manipulator 101 moves the tool to the designated position of the tool magazine 102 according to the preset trajectory. After the tool replacement is completed, the manipulator 101 again grasps the old tool back to its original position through the grasping component 2 and the anti-slip layer 3 or discards it to the designated tool recycling area.

[0037] A positioning slot 201 and a positioning plug-in 301 are also provided in this application. The positioning plug-in 301 is fixedly connected between the magnetic layer 302 and the anti-slip layer 3. A positioning slot 201 is opened inside the grabbing component 2, so that the positioning plug-in 301 and the magnetic layer 302 can be inserted into the interior of the positioning slot 201, and the magnetic layer 302 fits tightly to the inner wall of the positioning slot 201 and produces a magnetic state, thereby firmly connecting the anti-slip layer 3 to the grabbing component 2.

[0038] A roller 203 is also provided in the present application, wherein the grabbing assembly 2 is installed in the manipulator 101 for directly grabbing the tool. The roller 203 is movably installed at the initial grabbing position of the grabbing assembly 2 through a bearing. When the manipulator 101 starts to grab the tool, the roller 203 can reduce the friction during the initial contact between the tool and the grabbing assembly 2, so that the tool can enter the grabbing position more smoothly and come into contact with the anti-slip layer 3.

[0039] A splint 303 is also provided in this application. The splint 303 is made of hard material and is fixedly connected to the upper and lower ends of the anti-slip layer 3. The splint 303 is clamped on the outside of the grabbing component 2 to further ensure the stability of the anti-slip layer 3 on the grabbing component 2 and prevent it from shifting during the process of grabbing the tool.

[0040] The present application also provides a guide structure 4, a connector 401 and a built-in connecting groove 202. The guide structure 4 is specially constructed in a conical state, with its tip protruding outward. This design is intended to assist the tool to enter the grasping component 2 accurately and without error. At one end of the guide structure 4 facing the grasping component 2, a connector 401 is fixedly connected. At the same time, a built-in connecting groove 202 is provided on the grasping component 2. The built-in connecting groove 202 matches the shape and size of the connector 401. Through the guide structure 4, the connector 401 can be threaded into the built-in connecting groove 202. This design not only achieves a firm connection between the guide structure 4 and the grasping component 2, but also greatly facilitates the user to perform disassembly and assembly operations according to actual needs.

[0041] A protective sleeve 5 is also provided in this application. The protective sleeve 5 is designed with rubber material. In order to protect the guide structure 4 from erosion and damage from the external environment, the protective sleeve 5 is sleeved on the tip of the guide structure 4 to play a role of isolation and protection.

[0042] An insert 402 and a bonding layer 403 are also provided in the present application, wherein the front end opening of the built-in connecting groove 202 is larger to better accommodate other components. At the end of the guide structure 4 facing the grabbing component 2, in addition to the connecting member 401, an insert 402 is also provided. When the connecting member 401 is brought into the built-in connecting groove 202 for connection by rotation, the insert 402 is also driven at the same time and inserted into the front end of the built-in connecting groove 202. In addition, a bonding layer 403 made of rubber is glued to the insert 402. This bonding layer 403 can fit tightly with the front end of the inner wall of the built-in connecting groove 202, thereby effectively improving the stability and sealing of the connection between the guide structure 4 and the grabbing component 2.

The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and illustrated in the embodiments.
