[0031] Reference Figure 1 and Figure 3 As shown, this utility model provides a technical solution: a quick locking mechanism for a lathe tailstock, including a guide rail 1, a positioning device 2 inside the guide rail 1, and a fixing device 3 on one side of the guide plate 201.

[0032] The specific setup and function of the positioning device 2 and the fixing device 3 will be explained in detail below.

[0033] Reference Figure 2As shown in this embodiment: the positioning device 2 includes a guide plate 201, the interior of which is slidably connected to the guide rail 1. A tailstock 202 is fixedly connected to one side of the guide plate 201, and a cylinder 203 is fixedly connected to one side of the guide plate 201. A stop plate 204 is fixedly connected to the output end of the cylinder 203. An anti-slip plate 205 is fixedly connected to one side of the stop plate 204. A sliding plate 206 is fixedly connected to one side of the cylinder 203. An inner sliding groove plate 207 is slidably connected to the outside of the sliding plate 206. One side of the inner sliding groove plate 207 is fixedly connected to the guide rail 1. When the cylinder 203 starts, the output end drives the stop plate 204 to move horizontally. The stop plate 204 then pushes the anti-slip plate 205 towards the guide rail 1 until the anti-slip plate 205 is in close contact with the guide rail 1. At this time, due to the friction between the anti-slip plate 205 and the guide rail 1, the position of the guide plate 201 connected to the cylinder 203 can be fixed, ensuring that the guide plate 201 remains stable under the corresponding working conditions. Both sides of the cylinder 203 are fixedly connected to fixing blocks 208, and both sides of the fixing blocks 208 are provided with T-shaped grooves 209. This achieves the effect that the T-shaped grooves 209 are formed on the fixing blocks 208, and the fixing blocks 208 are fixed to the cylinder 203. A T-shaped plate 210 is slidably connected inside the T-shaped groove 209. This achieves the effect that the T-shaped plate 210 moves and slides within the T-shaped groove 209. A U-shaped plate 211 is fixedly connected to the side of the two T-shaped plates 210 that is far apart from each other, and one side of the two U-shaped plates 211 is fixedly connected to the abutment plate 204. This achieves the effect that the T-shaped plates 210 are fixed to the U-shaped plates 211, and the U-shaped plates 211 are fixed to the abutment plate 204. A telescopic rod 212 is fixedly connected to one end of the fixing block 208, and the output end of the telescopic rod 212 is fixedly connected to the U-shaped plate 211. This achieves the effect of the U-shaped plate 211 moving to drive the output end of the telescopic rod 212, preventing the U-shaped plate 211 from shifting position during movement.

[0034] Reference Figure 4 As shown in this embodiment: the fixing device 3 includes an L-shaped plate 31, one side of which is fixedly connected to the guide plate 201, and a fixing plate 32 is fixedly connected to one side of the guide plate 201. This achieves the effect of fixing the fixing plate 32 to the L-shaped plate 31, and fixing the L-shaped plate 31 to the guide plate 201. A reinforcing frame 36 is fixedly connected to one side of the L-shaped plate 31, and one side of the reinforcing frame 36 is fixedly connected to the guide plate 201. This achieves the effect of the reinforcing frame 36 preventing the L-shaped plate 31 from deforming. A force-bearing frame 33 is fixedly connected to one side of the fixing plate 32, and an anti-slip sleeve 34 is fixedly connected to the arc surface of the force-bearing frame 33. This achieves the effect of the anti-slip sleeve 34 increasing friction. A limiting block 35 is fixedly connected to the arc surface of the force-bearing frame 33, and one side of the limiting block 35 is fixedly connected to the L-shaped plate 31. This achieves the effect of the limiting block 35 preventing the force-bearing frame 33 from deforming.

[0035] Working principle: When it is necessary to lock the tailstock 202 via the positioning device 2, the operator first connects the cylinder 203 to the controller to accurately control the start and stop of the cylinder 203. Then, the cylinder 203 is started, and the output end of the cylinder 203 pushes the abutment 204 to move closer to the guide rail 1. During the movement of the abutment 204, the U-shaped plate 211 connected to it will drive the T-shaped plate 210 to slide synchronously in the T-groove 209. At the same time, the output end of the telescopic rod 212 remains extended, which effectively prevents the abutment 204 from shifting position during movement and ensures... The stability of the entire movement of the support plate 204 is ensured by the resistance generated when the anti-slip plate 205 is in close contact with the inner wall of the guide rail 1, which is sufficient to prevent the cylinder 203 from moving further. This fixes the position of the guide plate 201, which was originally slidable on the guide rail 1, and ultimately prevents the tailstock body 202 from moving, thus achieving reliable locking of the tailstock body 202. Through the positioning device 2, the problem of traditional lathe tailstock quick locking mechanisms, which mostly use bolts and nuts as locking components for the tailstock body 202, is solved. During operation, workers must manually loosen the locking nuts, and the entire process is driven by human power, which greatly increases the workload of workers.

[0036] When the tailstock 202 needs to be moved using the fixing device 3, the operator first releases the locking state of the tailstock 202, then holds the anti-slip sleeve 34 and applies a pulling force in the desired direction of movement. This pulling force is transmitted to the force-bearing frame 33, which drives the fixing plate 32 to move under the action of the pulling force. The movement of the fixing plate 32 is then transmitted to the L-shaped plate 31, causing the L-shaped plate 31 to drive the guide plate 201 to slide smoothly on the guide rail 1, ultimately realizing the movement of the tailstock 202. The fixing device 3 solves the problem of traditional lathe tailstock quick locking mechanisms lacking handles, which makes it uncomfortable for the operator's hands to exert force and difficult to find a suitable point of force when moving the tailstock.
