Description

Technical Field

[0001] This utility model relates to the field of electric spindle technology, and in particular to an electric spindle and an electric spindle cooling sleeve. Background Technology

[0002] The electric spindle is a core component of CNC machine tools. It drives the cutting tool to rotate, enabling the machining of workpieces. The electric spindle integrates a motor and generates a significant amount of heat during operation. If not dissipated promptly, the internal temperature will rise rapidly, causing thermal deformation of the spindle and affecting its speed, accuracy, and reliability. Therefore, spindle cooling is crucial. Typically, the electric spindle includes a cooling jacket, with cooling water flowing through its channels for cooling.

[0003] In existing electric spindle and electric spindle cooling sleeve technologies, it is inconvenient to disassemble the electric spindle and cooling sleeve when the cooling sleeve needs to be repaired or replaced, which in turn makes it inconvenient to repair or replace the cooling sleeve, thus greatly reducing work efficiency and limiting its practicality. Therefore, we propose an electric spindle and electric spindle cooling sleeve to solve this problem. Utility Model Content

[0012] In this utility model, an electric spindle and an electric spindle cooling sleeve are provided. By twisting the threaded rod, a movable disk threadedly connected to the threaded rod is easily moved forward, which in turn moves the inclined plate slidably connected to the movable disk downward. This causes the E-type insert plate and the T-type slider to move downward along the T-shaped groove, thereby causing the E-type insert plate to detach from the interior of the electric spindle body. Furthermore, the electric spindle body and the cooling sleeve body are no longer fixed together, making it easier to disassemble the electric spindle body and the cooling sleeve body, and thus easier to repair and replace the cooling sleeve body. This greatly improves work efficiency and has wider applicability. In this utility model, an electric spindle and an electric spindle cooling sleeve are provided. By pulling the pull ring, the inserted rod fixed thereto begins to move, causing the inserted rod to disengage from the cooling sleeve body. This removes the fixing between the connecting cylinder and the cooling sleeve body, allowing the movable disc fixed to the connecting cylinder to move easily. This utility model has a reasonable structural design. The mutual cooperation between the threaded rod, moving disc, fixed disc, inclined plate and E-type insert plate facilitates the disassembly of the electric spindle body and the cooling jacket body, thereby facilitating the maintenance and replacement of the cooling jacket body, which greatly improves work efficiency and has wider applicability.

The outside of the insert rod 15 is slidably connected to the inside of the connecting cylinder 13. The second return spring 17 is sleeved on the outside of the insert rod 15. A pull ring 18 is fixedly installed on the top of the insert rod 15. The bottom end of the insert rod 15 is movably inserted into the inside of the cooling jacket body 2, so as to facilitate the restriction of the movement of the movable disk 3 by the insert rod 15.

[0018] In this embodiment, two guide posts 9 are fixedly installed on one side of the fixed disk 4. One end of each guide post 9 is fixedly connected to one side of the movable disk 3. Two first return springs 10 are fixedly connected to one side of the fixed disk 4. One end of each first return spring 10 is fixedly connected to one side of the movable disk 3. The two first return springs 10 are sleeved on the outside of the corresponding guide posts 9, making the movable disk 3 more stable when it moves.

[0019] In this embodiment, the inlet of the cooling jacket body 2 is connected to the inlet pipe 19, the outlet of the inlet pipe 19 is connected to the cooling chamber 11, the outlet of the cooling jacket body 2 is connected to the outlet pipe 21, the inlet of the outlet pipe 21 is connected to the cooling chamber 11, a first sealing plug 20 is movably inserted into the inside of the inlet pipe 19, and a second sealing plug 22 is movably inserted into the inside of the outlet pipe 21, so as to facilitate the replacement of the coolant inside the cooling chamber 11.

[0020] In this embodiment, a plurality of threaded rods 12 are rotatably mounted inside the fixed disk 4, and the outer sides of the plurality of threaded rods 12 are threadedly connected to the inside of the movable disk 3, so as to facilitate the movement of the movable disk 3 by means of the threaded rods 12.

After the coolant delivery is complete, the first sealing plug 20 is reinserted, thus facilitating the cooling of the electric spindle body 1. Simultaneously, when maintenance or replacement of the cooling jacket body 2 is required, the pull ring 18 is first pulled to move the fixed insert rod 15, causing the insert rod 15 to disengage from the cooling jacket body 2. This removes the fixing between the connecting cylinder 13 and the cooling jacket body 2, allowing the movable disc 3 fixed to the connecting cylinder 13 to move easily. Then, the threaded rod 12 is twisted to facilitate the movement of the threaded rod 15. The threaded movable disk 3 moves forward, which in turn drives the inclined plate 5, which is slidably connected to the movable disk 3, to move downward. This causes the E-type insert plate 6 and the T-type slider 7 to move downward along the T-type slide groove 8, thereby causing the E-type insert plate 6 to detach from the interior of the electric spindle body 1. This further removes the fixing between the electric spindle body 1 and the cooling sleeve body 2, making it easier to disassemble the electric spindle body 1 and the cooling sleeve body 2, and thus easier to repair and replace the cooling sleeve body 2. This greatly improves work efficiency and expands its practicality. After the repair and replacement of the cooling sleeve body 2 is completed, the above operation is repeated in reverse so that the electric spindle body 1 and the cooling sleeve body 2 are fixed again.
