[0021] Please refer to Figures 1-3 The utility model provides the following technical scheme:

[0022] Specifically refers to a kind of automatic unloading mechanism for numerical control lathe, including chuck 1, four movable grooves 2 extending out the side of chuck 1 are arranged on the outer surface of chuck 1, and four movable grooves 2 are arranged in circumferential array on chuck 1, four L-shaped clamping legs 3 are arranged in four movable grooves 2, L-shaped clamping leg 3 horizontal plate is arranged in movable groove 2 and slides in movable groove 2, L-shaped clamping leg 3 vertical plate extends out the side of chuck 1, and placing groove 4 is arranged on the side of chuck 1, so that one end of workpiece is inserted into placing groove 4, four L-shaped clamping legs 3 are displaced to one side of placing groove 4, so that four L-shaped clamping leg vertical plates extrude the outer surface of workpiece, thereby completing the fixation of workpiece.

[0023] In the embodiment, the side of L-shaped clamping leg 3 vertical plate close to placing groove 4 is provided with friction layer 15, so as to increase the friction between L-shaped clamping leg 3 and workpiece, further guarantee the fixing effect of workpiece, and avoid the problem of loosening of workpiece during machining as much as possible.

[0024] Specifically, built-in cavity 5 is arranged in chuck 1, push plate 6 is arranged in placing groove 4, movable push rod 7 is fixedly connected to the side surface of push plate 6 facing built-in cavity 5, the other end of movable push rod 7 is slidably penetrated into built-in cavity 5, one end of movable push rod 7 in built-in cavity 5 is fixedly connected with extrusion plate 8, spring 9 is fixedly connected between extrusion plate 8 and the inner wall of built-in cavity 5, and spring 9 is movably sleeved on the outer surface of movable push rod 7.

[0025] When the workpiece is finished, extrusion plate 8 is pushed to displace to one side of placing groove 4, and spring 9 is contracted under stress, at this time, movable push rod 7 pushes push plate 6 to displace in placing groove 4, so that one end of workpiece in placing groove 4 can be pushed out, and the product can be automatically ejected after machining on numerical control lathe, so that the degree of automation is high, the operation is convenient and fast, and manpower is saved.

[0026] Specifically, the inner wall of the built-in cavity 5 is fixedly connected with a clamping air cylinder 10, and the telescopic end of the clamping air cylinder 10 is fixedly connected with a control push plate 11.
