[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figures 1 to 6 shown, the present utility model provides a servo motor spindle for quickly locking a spindle, including:

[0027] A servo motor main body 1, a fixed tube 2 is fixedly sleeved inside the left side of the servo motor main body 1. Locking grooves 22 are respectively opened at the top and bottom inside the fixed tube 2. A spindle body 3 is movably sleeved inside the fixed tube 2. A limiting groove 4 is opened at the left side of the top of the spindle body 3. Long grooves 5 are respectively opened at the right sides of the top and bottom of the spindle body 3;

[0028] A locking mechanism, which is arranged inside the long groove 5;

[0029] Among them, the locking mechanism includes a locking block 6. The top of the locking block 6 is movably connected to the inside of the locking groove 22. The outer surface of the locking block 6 is movably connected to the inside of the long groove 5. A spring 7 is fixedly installed on the right side of the bottom of the locking block 6. The other end of the spring 7 is fixedly installed with a square block 8. The right side of the square block 8 is fixedly connected to the right side inside the spindle body 3. The left side of the bottom of the locking block 6 is movably connected to a pressing block 9. The outer surface of the pressing block 9 is movably sleeved inside the spindle body 3. A moving block 10 is fixedly installed at the top of the pressing block 9. The top of the moving block 10 extends above the top of the spindle body 3 through the limiting groove 4. The outer surface of the top right side of the moving block 10 is movably connected to the left side of the fixed tube 2.

[0030] Due to the limiting effect inside the limiting groove 4, the moving block 10 can only move left and right. When the moving block 10 drives the pressing block 9 to move right along the inside of the spindle body 3, at this time, the outer surface on the right side of the pressing block 9 will simultaneously press the two locking blocks 6 during the rightward movement. At this time, the two locking blocks 6 will move away from each other under the limitation of the two long grooves 5. At the same time, the two springs 7 will be in a stretched state. Due to the elastic force of the two springs 7, a good reset effect will be exerted on the two locking blocks 6. When the opposite ends of the two locking blocks 6 move into the inside of the two locking grooves 22, at this time, the entire spindle body 3 will be locked inside the fixed tube 2.

[0031] Among them, a fixed block 11 is fixedly installed at the top of the left side of the fixed tube 2. A blocking block 12 is movably sleeved inside the fixed block 11. The other end of the blocking block 12 is movably sleeved inside the moving block 10.

[0032] When the outer surface of the stopper 12 is movably sleeved inside the moving block 10, the stopper 12 will block the movement of the moving block 10 at this time.

[0033] Wherein, positioning blocks 13 are fixedly installed on both the front and rear sides of the main shaft body 3, and the outer surface of the positioning block 13 is movably connected to the inside of the fixed pipe 2.

[0034] Due to the positioning of the two positioning blocks 13, when the entire main shaft body 3 is located inside the fixed pipe 2, the two locking blocks 6 and the two locking grooves 22 will be in the same vertical plane at this time.

[0035] Wherein, a threaded rod 14 is fixedly installed on the left side of the main shaft body 3, a short pipe 15 is fixedly installed on the left side of the threaded rod 14, and short grooves 16 are formed at both the top and bottom of the short pipe 15.

[0036] Due to the design of the two short grooves 16, the object located inside them will be limited, allowing it to move only left and right.

[0037] Wherein, a telescopic rod 17 is movably sleeved inside the short pipe 15, a round shaft 18 is fixedly installed on the left side of the telescopic rod 17, and the right side of the round shaft 18 is movably connected to the left side of the short pipe 15.

[0038] Due to the design inside the short pipe 15, the telescopic rod 17 can move left and right along the inside of the short pipe 15.

[0039] Wherein, movable blocks 19 are fixedly installed at both the top and bottom on the right side of the outer surface of the telescopic rod 17, the other end of the movable block 19 extends outside the short pipe 15 through the short groove 16, and a moving pipe 20 is fixedly installed at the other end of the movable block 19.

[0040] When the moving pipe 20 moves to the left, the two movable blocks 19 will move to the left under the drive of the moving pipe 20. Immediately afterwards, the two movable blocks 19 will drive the round shaft 18 to move to the left through the telescopic rod 17. [[ID=Twenty-five]] [[ID=Twenty-six]]

[0041] [[ID=Twenty-seven]]Wherein, a rotating ring 21 is movably sleeved on the outer surface of one end on the right side of the moving pipe 20, and the inside of the rotating ring 21 is threadedly sleeved on the outer surface of the threaded rod 14. [[ID=Twenty-eight]] [[ID=Twenty-nine]]

[0042] [[ID=Thirty]]When the rotating ring 21 rotates along the outer surface of the threaded rod 14, the rotating ring 21 will move to the left while rotating at this time. At this time, the moving pipe 20 will move to the left under the drive of the rotating ring 21. [[ID=Thirty-one]] [[ID=Thirty-two]]

[0043] [[ID=Thirty-three]]The working principle and usage process of the present utility model: [[ID=Thirty-four]] [[ID=Thirty-five]]

[0044] First, the operator inserts the right end of the spindle body 3 into the inside of the fixed tube 2. Due to the positioning effect of the two positioning blocks 13, at this time, the two locking grooves 22 and the two locking blocks 6 will be in the same vertical plane. When the right side of the spindle body 3 contacts the right side inside the fixed tube 2, the operator then pulls the moving block 10. Due to the design inside the limiting groove 4, the movement of the moving block 10 will be limited. At this time, the moving block 10 will move to the right along the inside of the limiting groove 4. Then, the pressing block 9 will drive along the inside of the spindle body 3 to the right under the drive of the moving block 10. Due to the design on the right side of the pressing block 9, the right side of the pressing block 9 will simultaneously squeeze and push the two locking blocks 6 during the rightward movement, causing the two locking blocks 6 to move. Due to the design inside the two long grooves 5, the movement of the two locking blocks 6 will be limited. At this time, the two locking blocks 6 will move away from each other. Then, the two springs 7 will be in a stretched state. Subsequently, the opposite ends of the two locking blocks 6 will respectively move into the two locking grooves 22. At this time, the whole spindle body 3 will be locked inside the fixed tube 2 under the cooperation of the two locking blocks 6 and the two locking grooves 22, thus realizing the function of quickly locking the spindle body 3. Then, the operator pushes the stop block 12 to make the stop block 12 move backward. When the rear end of the stop block 12 is located inside the moving block 10, the stop block 12 will block the movement of the moving block 10, thereby preventing the whole moving block 10 from moving to the left.

[0045] Subsequently, the operator rotates the rotating ring 21 along the outer surface of the threaded rod 14. Since the inside of the rotating ring 21 is threadedly sleeved with the outer surface of the threaded rod 14, at this time, the rotating ring 21 will move to the left while rotating. Immediately afterwards, the moving tube 20 will move to the left under the drive of the rotating ring 21. Then, the two movable blocks 19 will move to the left under the drive of the moving tube 20. Subsequently, the two movable blocks 19 will drive the telescopic rod 17 to move to the left along the inside of the short tube 15. Then, the round shaft 18 will move to the left under the drive of the telescopic rod 17, thus realizing the function of telescoping the round shaft 18 according to the usage requirements.
