Abstract
Description
Technical Field
[0001] This utility model relates to the field of cyclone milling machine technology, and in particular to a fixing device for CNC cyclone milling machines. Background Technology
[0002] The cyclone milling machine is an advanced thread-machining machine that cleverly applies milling techniques to thread machining. This machine is typically used in conjunction with a lathe and is primarily used for thread processing. During the machining process, the cyclone milling machine utilizes carbide forming tools, with the cutter head rotating at high speed, to mill the workpiece.
[0003] In the machining process of a cyclone milling machine, the workpiece is held in place by a gripper assembly. Over prolonged use, the gripping surfaces of the grippers gradually wear down due to friction and aging, resulting in decreased anti-slip performance and ineffective workpiece securing. Traditional maintenance methods involve periodically replacing the entire gripper assembly; however, this method is not only cumbersome but also increases costs. Therefore, there is an urgent need for a gripper assembly that is easy to maintain and cost-effective. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fixing device for CNC milling machines.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A fixing device for a CNC milling machine includes a gripper assembly. The gripper assembly has multiple gripping jaws movably disposed thereon. Each gripping jaw has two limiting members movably disposed thereon, and each gripping jaw has a detachable gripping surface. Multiple mounting posts are fixedly and vertically disposed on the top of the gripping surface. Each mounting post is adapted to be inserted into the gripping jaw, and limiting cavities are formed on both sides of the mounting posts corresponding to the limiting members.
[0007] In addition, a preferred structure is that the clamping claw has two transversely extending movable cavities, and the limiting members are all located within the movable cavities.
[0008] In addition, a preferred structure is that multiple guide posts are fixedly installed in each of the movable cavities, and the limiting members are guided to move by the guide posts.
[0009] In addition, a preferred structure is that the bottom of the clamping claw has multiple mounting cavities that are open upwards, all of which are connected to the movable cavity and are adapted to the mounting post.
[0010] In addition, a preferred structure is that multiple springs are provided on the side of the active cavity away from the mounting cavity, facing the limiting member, and the other end of each spring is connected to the limiting member, and the springs are all located outside the guide post.
[0011] Furthermore, in a preferred configuration, when the mounting post is fully inserted into the mounting cavity, the limiting cavity is aligned with the movable cavity.
[0012] The beneficial effects of this utility model are as follows: by setting the clamping claw and the clamping surface as a modular structure, and by using a limiting component to realize the assembly connection between the clamping claw and the clamping surface, when the clamping surface is worn, only the clamping surface needs to be replaced, which not only facilitates maintenance, but also saves maintenance costs.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Reference Figure 1-5A fixing device for a CNC milling machine includes a gripper assembly 1. Multiple gripping jaws 2 are movably disposed on the gripper assembly 1. Each gripping jaw 2 has two movably disposed limiting members 4, and each gripping jaw 2 is equipped with a detachable gripping surface 3. Multiple mounting posts 31 are vertically fixed upwards at the top of the gripping surface 3. Each mounting post 31 is adapted to be inserted into the gripping jaw 2, and limiting cavities 32 are formed on both sides of each mounting post 31 corresponding to the limiting members 4.
[0021] The clamping claw 2 has two transversely extending movable cavities 22, and the limiting members 4 are both located and move within the movable cavities 22. Multiple guide posts 221 are fixedly installed within each movable cavity 22, and the limiting members 4 are guided to move by the guide posts 221. The guide posts 221 not only improve the stability of the limiting members 4 during movement but also prevent the limiting members 4 from falling out of the movable cavities 22.
[0022] The bottom of the clamping claw 2 has multiple mounting cavities 21 that are open upwards. All mounting cavities 21 are connected to the movable cavity 22 and are adapted to the mounting post 31.
[0023] In this design, multiple springs 222 are arranged on the side of the movable cavity 22 away from the mounting cavity 21, facing the limiting member 4. The other end of each spring 222 is connected to the limiting member 4, and the springs 222 are all located outside the guide post 221. Through the elastic force of the springs 222, the limiting member 4 can be pushed towards the center, thereby allowing the limiting member 4 to be securely locked in the limiting cavity 32.
[0024] When the mounting post 31 is fully inserted into the mounting cavity 21, the limiting cavity 32 is adapted and aligned with the movable cavity 22.
[0025] In this embodiment, the gripping claws 2 move on the gripping claw assembly 1 via a motor drive, thereby securing the workpiece firmly onto the gripping claw assembly 1 through the pressing action of multiple gripping claws 2. It is worth noting that the specific operating methods and connection structures between the gripping claw assembly 1 and the gripping claws 2 are existing technologies and do not fall under the technical problem of reducing maintenance costs that this technical solution aims to address.
[0026] Furthermore, by setting the clamping jaw 2 and the clamping surface 3 into a modular structure, when the clamping surface 3 shows signs of aging and wear during long-term use, only the clamping surface 3 needs to be replaced, without replacing the entire clamping jaw 2, thus reducing the overall maintenance cost of the clamping jaw assembly 1. It is worth noting that anti-slip pads are provided on the clamping surface 3 to improve the clamping effect on the workpiece.
[0027] Furthermore, when the user needs to install the clamping surface 3 onto the clamping claw 2, they only need to move the limiting members 4 on both sides to the sides through the locking grooves, at which point the springs 222 are compressed. Then, the user simply inserts the mounting post 31 on the clamping surface 3 into the mounting cavity 21, at which point the limiting cavities 32 on the mounting post 31 are aligned with the limiting members 4 in the movable cavity 22. Finally, the user simply releases the limiting members 4 on both sides, at which point the limiting members 4 automatically reset and move into the limiting cavities 32 by the elastic force of the springs 222. Thus, the mounting post 31 is fixed by the mutual locking between the limiting members 4 and the limiting cavities 32, thereby achieving the fixed assembly of the clamping surface 3 onto the clamping claw 2.
[0028] Furthermore, when the user needs to remove and replace the clamping surface 3, they only need to pull the two limiting members 4 to the sides again to release the locking between the limiting members 4 and the limiting cavity 32. At this time, the mounting post 31 can automatically fall out of the mounting cavity 21 by its own weight, thereby realizing the disassembly of the clamping surface 3.
[0029] In this embodiment, by setting the clamping claw 2 and the clamping surface 3 as a modular structure, and by using the limiting member 4 to realize the assembly connection between the clamping claw 2 and the clamping surface 3, when the clamping surface 3 is worn, only the clamping surface 3 needs to be replaced, which not only facilitates maintenance, but also saves maintenance costs.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
