A high-performance spindle can provide stable rotational motion and sufficient power, thereby improving machining efficiency. The rotational accuracy and rigidity of the spindle directly affect the machining accuracy and surface quality of the workpiece.

[0003] When assembling the spindle mechanism, lubricant needs to be added between the mounting base and the spindle body to reduce wear on the contact surfaces. However, after long-term use, the lubricant between the mounting base and the spindle body of the existing spindle mechanism is consumed. When adding lubricant again, the entire structure at the connection point must be disassembled and reassembled, which can easily cause time and effort for workers and affect work efficiency. Utility Model Content

[0021] 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.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A precision lathe spindle mechanism includes a spindle box 1, a mounting base 2 fixedly connected to the surface of the spindle box 1, a spindle body 3 rotatably connected to the inner surfaces of the spindle box 1 and the mounting base 2, a clamp 4 fixedly connected to the surface of the spindle body 3, a storage compartment 5 abuttingly connected to the surface of the mounting base 2, a feed hole 6 and a connecting hole 9 on one side of the storage compartment 5, a discharge hole 7 on the other side of the storage compartment 5, a through hole 8 and a threaded groove 21 on the surface of the mounting base 2, a support spring 10 and a stop block 11 movably connected to the inner surface of the storage compartment 5, a support plate 14 and a side plate 19 fixedly connected to the outer surface of the storage compartment 5, a connecting rod 12 slidably connected to the surface of the connecting hole 9, and a pull plate 13 mounted on the surface of the connecting rod 12. A fixing block 15 is fixedly connected to the surface of plate 14, and a movable plate 16 is movably connected to the surface of support plate 14. One end of the movable plate 16 has a rotating hole 17, and the other end of the movable plate 16 has a slot 18. The surface of side plate 19 has an insertion hole 20, and bolts 22 are installed on the surface of side plate 19. The main body of the spindle mechanism consists of spindle box 1, mounting base 2, spindle body 3, and clamp 4. The spindle box 1 is equipped with an existing motor. When using the spindle mechanism, the motor in the spindle box 1 drives the spindle body 3 to rotate, thereby rotating the object clamped on the clamp 4. The inner side of the storage compartment 5 is truncated cone-shaped near the discharge hole 7, which allows the lubricant to enter the discharge hole 7 and the through hole 8 more smoothly.

[0024] Furthermore, the surfaces of the discharge hole 7 and the through hole 8 are square. The size of the discharge hole 7 is smaller than that of the stop block 11. The diameter of the connecting hole 9 is the same as that of the connecting rod 12. The length and width of the discharge hole 7 and the through hole 8 are the same. The lubricant inside the storage compartment 5 can flow into the mounting base 2 and the main shaft body 3 through the discharge hole 7 and the through hole 8. The connecting hole 9 can be used to install the connecting rod 12.

[0025] Furthermore, the support spring 10 is sleeved on the surface of the connecting rod 12. One end of the support spring 10 is fixedly connected to the inner surface of the storage compartment 5, and the other end of the support spring 10 is fixedly connected to the surface of the stop block 11. The stop block 11 is abutted against the inner surface of the storage compartment 5. The surface of the stop block 11 is frustoconical. Under the action of the support spring 10, a supporting force can be applied to the surface of the stop block 11, and the stop block 11 and the connecting rod 12 always tend to move towards the discharge hole 7. There is a gap between the stop block 11 and the storage compartment 5. When the stop block 11 no longer blocks the discharge hole 7, the lubricant can flow out through the gap.

[0026] Furthermore, the surface of the connecting rod 12 is cylindrical, one end of the connecting rod 12 is fixedly connected to the surface of the stop block 11, and the other end of the connecting rod 12 is fixedly connected to the surface of the pull plate 13. The surface of the pull plate 13 is long plate-shaped. The connecting rod 12 can realize the connection effect between the pull plate 13 and the stop block 11. Then, by pulling the pull plate 13, the stop block 11 can be moved together.

[0027] Furthermore, the surface of the support plate 14 is rectangular, and the cross-section of the fixing block 15 is "T" shaped. The inner diameter of the fixing block 15 is the same as the diameter of the rotating hole 17, and the outer diameter of the fixing block 15 is larger than the diameter of the rotating hole 17. The movable plate 16 is rotatably connected to the surface of the fixing block 15 through the rotating hole 17. One side of the support plate 14 is fixed to the clamp 4, while the other side is connected to the movable plate 16. The support plate 14 allows the position of the movable plate 16 to be higher than the height of the pull plate 13 when the stop block 11 abuts against the inside of the storage compartment 5. This allows the movable plate 16 to engage with the connecting rod 12 through the slot 18 when the discharge hole 7 is opened, thereby limiting the stop block 11 and preventing the pull plate 13 from being pulled continuously. The area of ​​the slot 18 is larger than the cross-sectional area of ​​the connecting rod 12. With the connection between the fixing block 15 and the rotating hole 17, the movable plate 16 can rotate around the fixing block 15.

[0028] Furthermore, the surface of the side plate 19 is arc-shaped. The side plate 19 is installed on the outer surface of the mounting base 2. There are two sets of side plates 19 and threaded grooves 21. The two sets of side plates 19 are fixedly connected to both sides of the storage compartment 5. The two sets of threaded grooves 21 are opened on both sides of the mounting base 2. The surface of the insertion hole 20 is circular. Under the action of the insertion hole 20 and the threaded groove 21, the installation effect of the bolt 22 can be achieved.

[0029] Furthermore, the bolt 22 is inserted into the surface of the insertion hole 20. One end of the bolt 22 is threaded into the surface of the threaded groove 21, and the other end of the bolt 22 is abutted into the surface of the side plate 19. The bolt 22 passes through the insertion hole 20 and penetrates the surface of the side plate 19. With the connection of the bolt 22, the insertion hole 20, and the threaded groove 21, the connection between the side plate 19 and the mounting base 2 can be achieved, thereby realizing the disassembly and assembly of the storage compartment 5.

[0030] Working principle: When adding lubricant between the mounting seat 2 and the spindle body 3 on the spindle mechanism, first stop the entire precision lathe and pull the pull plate 13 to drive the connecting rod 12 to slide on the surface of the connecting hole 9, and release the abutment between the stop block 11 and the inner side of the storage compartment 5, while the support spring 10 is in a compressed state. When the position of the pull plate 13 is higher than the movable plate 16, the movable plate 16 is rotated through the rotating hole 17 and centered on the fixed block 15, so that the connecting rod 12 is engaged in the slot 18. Then, the pull plate 13 is released and pressed against the movable plate 16 to limit the opening of the stop block 11. Then, the lubricant in the storage compartment 5 flows into the surface of the spindle body 3 through the discharge hole 7 and the through hole 8 along the gap with the stop block 11. Finally, the spindle body 3 is rotated to spread the lubricant evenly.

[0031] When the worker adds lubricant to the storage compartment 5, he first uses a wrench or other tools to rotate the two sets of bolts 22 in sequence, so that the bolts 22 move on the surface of the threaded groove 21 through the thread and cancel the engagement effect with the side plate 19. Then, the bolts 22 are removed from the insertion hole 20. After that, the entire storage compartment 5 can be removed from the surface of the mounting base 2. Finally, the lubricant can be injected into the storage compartment 5 through the feed hole 6.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
