Description

Technical Field

[0001] This utility model relates to the field of spindles, specifically a spindle that is easy to maintain. Background Technology

[0002] Electric spindles are a relatively recent technology in the CNC machine tool field, integrating the machine tool spindle and spindle motor into one unit. High-speed CNC machine tool main drive systems eliminate belt drives and gear drives. The machine tool spindle is directly driven by an internal electric motor, thus shortening the main drive chain to zero and achieving "zero transmission" for the machine tool. Routine maintenance mainly involves cleaning, which may seem like a small matter, but plays a significant role in extending the lifespan of high-speed electric spindles! The spindle motor is a component that wears down daily; to extend its lifespan, it is essential to provide it with a good working environment through proper maintenance! Routine maintenance of the spindle motor should focus on the following aspects.

[0003] Currently, some high-performance electric spindles that are easy to maintain are inconvenient to install and disassemble, and difficult to clean.

[0004] The present invention aims to solve the technical problems existing in the prior art, and to this end, proposes a spindle that is easy to maintain. Utility Model Content

[0005] The purpose of this invention is to provide a spindle that is easy to maintain, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A spindle that is easy to maintain includes a housing and a fixed block. The housing and the fixed block are fixedly connected. A drive mechanism is rotatably connected to the cylindrical surface of the fixed block. An installation device is provided inside the fixed block. The drive mechanism cooperates with the installation device.

[0008] The housing contains a main spindle body, which is fitted with a mounting device.

[0009] As a further embodiment of this utility model: the cylindrical surface is provided with an external thread, which is threadedly connected to the drive mechanism, and the cylindrical surface of the fixed block is provided with a limit groove.

[0010] As a further embodiment of this utility model: the driving mechanism includes a driving component, which is sleeved on the cylindrical surface of the fixed block and rotatably connected to the fixed block. The driving component is threadedly connected to an external thread. A connecting groove is provided on one side of the driving component. The connecting groove is a closed annular shape. The driving component is connected to the mounting device.

[0011] As a further embodiment of this utility model: the installation device includes a movable rod, which is located within a fixed block and slides horizontally in contact with the fixed block. A push plate is fixedly connected to the cylindrical surface of the movable rod. The push plate passes through a limiting groove and slides in contact with the fixed block. A connecting rod is fixedly connected to one side of the push plate. The other end of the connecting rod extends into a connecting groove and slides in contact with a driving component. Several fixed grippers are rotatably connected to the cylindrical surface of the movable rod. The fixed grippers and the movable rod form a lever shape. One side of the fixed grippers slides in contact with the fixed block. The fixed grippers cooperate with the main shaft body.

[0012] As a further embodiment of this utility model: the main body of the spindle includes a motor spindle, the motor spindle extends into the outer shell, a shock-absorbing pad is fixedly connected to the inner surface of the outer shell, the motor spindle slides in contact with the shock-absorbing pad, a connecting block is fixedly connected to one side of the motor spindle, and the cylindrical surface of the connecting block has several slots, which cooperate with the fixed clamps.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When the device is in use, the motor spindle is placed inside the housing, the connecting block contacts the moving rod, and then the driving component is rotated. Since the driving component is threadedly connected to the external thread, when the driving component rotates, it will move horizontally. Because the driving component is connected to the connecting rod through the connecting groove, and the connecting groove is a closed annular shape, the rotation of the driving component with the connecting groove does not affect the connection between the driving component and the connecting rod. When the driving component moves to the right, the driving component drives the connecting rod to move through the connecting groove, and the connecting rod moves through the push plate. The moving rod moves, causing the fixed gripper to move to the right. Since the fixed gripper and the moving rod form a lever shape, the right side of the fixed gripper slides into contact with the fixed block. That is, when the fixed gripper moves to the right, it is squeezed by the fixed block, causing the right side of the fixed gripper to expand outward. Then, the other end of the fixed gripper extends into the slot to clamp and fix the connecting block, thus realizing the installation of the motor spindle. Conversely, when the driving component moves to the left, the installation of the motor spindle is canceled, which facilitates the installation or removal of the motor spindle. This device facilitates the installation and removal of the electric spindle and makes it easy to clean the electric spindle. Attached Figure Description

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0020] Example 1

[0021] Please see Figure 1-3 In this embodiment of the utility model, a spindle that is easy to maintain includes a housing 1 and a fixing block 2. The housing 1 and the fixing block 2 are fixedly connected. The cylindrical surface of the fixing block 2 is rotatably connected to a driving mechanism. An installation device is provided inside the fixing block 2. The driving mechanism and the installation device cooperate with each other.

[0022] The housing 1 contains a main spindle body, which is fitted with a mounting device. This device facilitates the installation and disassembly of the electric spindle and the cleaning of the electric spindle.

[0023] Example 2

[0024] Please see Figure 1-3 Based on Embodiment 1, the two cylindrical surfaces are further provided with external threads 3, which are threadedly connected to the drive mechanism, and the cylindrical surface of the fixed block 2 is provided with a limit groove 6.

[0025] Furthermore, the driving mechanism includes a driving component 4, which is sleeved on the cylindrical surface of the fixed block 2 and rotatably connected to the fixed block 2. The driving component 4 is threadedly connected to the external thread 3. A connecting groove 5 is provided on one side of the driving component 4. The connecting groove 5 is in the shape of a closed ring. The driving component 4 is connected to the mounting device. When the driving component 4 is rotated, it will move horizontally because it is threadedly connected to the external thread 3. Since the driving component 4 is connected to the connecting rod 8 through the connecting groove 5, which is in the shape of a closed ring, the rotation of the connecting groove 5 by the driving component 4 does not affect the connection between the driving component 4 and the connecting rod 8. When the driving component 4 moves to the right, it drives the connecting rod 8 to move through the connecting groove 5.

[0026] Furthermore, the installation device includes a movable rod 13, which is located within the fixed block 2 and slides horizontally in contact with the fixed block 2. A push plate 7 is fixedly connected to the cylindrical surface of the movable rod 13. The push plate 7 passes through the limiting groove 6 and slides in contact with the fixed block 2. A connecting rod 8 is fixedly connected to one side of the push plate 7, and the other end of the connecting rod 8 extends into the connecting groove 5 and slides in contact with the driving component 4. A plurality of fixed grippers 12 are rotatably connected to the cylindrical surface of the movable rod 13. The fixed grippers 12 and the movable rod 13 form a lever shape. One side slides in contact with the fixed block 2, and the fixed clamp 12 cooperates with the main shaft body. The connecting rod 8 drives the moving rod 13 to move through the push plate 7. The moving rod 13 drives the fixed clamp 12 to move to the right. Since the fixed clamp 12 and the moving rod 13 form a lever shape, the right side of the fixed clamp 12 slides in contact with the fixed block 2. That is, when the fixed clamp 12 moves to the right, the fixed clamp 12 is squeezed by the fixed block 2, causing the right side of the fixed clamp 12 to expand outward. Then the other end of the fixed clamp 12 extends into the slot 14 to clamp and fix the connecting block 11.

[0027] Furthermore, the main body of the spindle includes a motor spindle 10, which extends into the outer shell 1. A shock-absorbing pad 9 is fixedly connected to the inner surface of the outer shell 1. The motor spindle 10 slides in contact with the shock-absorbing pad 9. A connecting block 11 is fixedly connected to one side of the motor spindle 10. The cylindrical surface of the connecting block 11 is provided with several slots 14, which cooperate with the fixed clamps 12.

[0028] The working principle of this utility model is as follows: When the device is in use, the motor spindle 10 is placed inside the outer casing 1, the connecting block 11 contacts the moving rod 13, and then the driving component 4 is rotated. Since the driving component 4 is threadedly connected to the external thread 3, when the driving component 4 rotates, the driving component 4 will move horizontally. Since the driving component 4 is connected to the connecting rod 8 through the connecting groove 5, and the connecting groove 5 is a closed annular shape, that is, when the driving component 4 drives the connecting groove 5 to rotate, it does not affect the connection between the driving component 4 and the connecting rod 8. When the driving component 4 moves to the right, the driving component 4 drives the connecting rod 8 to move through the connecting groove 5, and the connecting rod 8 drives the moving rod 13 to move through the push plate 7. When the moving rod 13 moves, it drives the fixed clamp 12 to move to the right. Since the fixed clamp 12 and the moving rod 13 form a lever shape, the right side of the fixed clamp 12 slides into contact with the fixed block 2. That is, when the fixed clamp 12 moves to the right, the fixed clamp 12 is squeezed by the fixed block 2, causing the right side of the fixed clamp 12 to expand outward. Then, the other end of the fixed clamp 12 extends into the slot 14 to clamp and fix the connecting block 11, thus realizing the installation of the motor spindle 10. Conversely, when the driving component 4 moves to the left, the installation of the motor spindle 10 is canceled, which facilitates the installation or removal of the motor spindle 10. This device facilitates the installation and removal of the electric spindle and the cleaning of the electric spindle.
