[0022] The utility model discloses a lathe tailstock ejector repeated positioning device which is mainly used in the process of lathe processing. Since the workpiece blank has a certain error, when the tailstock ejector of the lathe is withdrawn, the workpiece is easily shaken and displaced, resulting in deviation when it is clamped with the ejector next time, resulting in cumulative error, making it impossible for the ejector to clamp the workpiece.

[0023] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A lathe tailstock ejector repeated positioning device comprises a positioning member 1, the bottom end of the positioning member 1 is fixedly connected to a base 8, an ejector body 2 is arranged at the front end of the positioning member 1, a convex groove 15 is provided at the front end of the positioning member 1 below the ejector body 2, and also comprises a positioning mechanism: the positioning mechanism comprises a spring frame 3 slidably connected inside the convex groove 15, a protective plate 4 is fixedly connected to the top of the spring frame 3, an empty groove 14 is provided above the spring frame 3, a clamping assembly is provided inside the empty groove 14, a movable groove 11 is provided on one side of the spring frame 3, a driving assembly is provided inside the convex groove 15, a rotating gear 13 is rotatably connected inside the movable groove 11, and a connecting rod 10 is fixedly connected to one end of the rotating gear 13; a repeating mechanism: the repeating mechanism is arranged above the spring frame 3.

[0024] In this solution, when the staff operates the lathe, by setting a positioning mechanism, when the spring frame 3 is retracted to the inside of the convex groove 15, the fixed plate 7 is extended to the inside of the movable groove 11, and the rack 12 drives the rotating gear 13 to rotate, so that the clamping block 9 threadedly connected to one end of the connecting rod 10 slides, clamps and positions the object placed above the spring frame 3, and increases the stability of object processing.

[0025] Among them, refer to Figure 2 and Figure 3 In a preferred embodiment, the repeating mechanism includes a connecting block 5 arranged above the spring frame 3, and a reset assembly is installed below the ejector body 2.

[0026] In this solution, by providing a repeating mechanism, when the connecting block 5 squeezes the mounting block 6, the ejector body 2 can be driven to shrink into the interior of the positioning member 1, so that the ejector body 2 releases the positioning of the upper object and performs secondary positioning on the lower object.

[0027] Further, see Figure 3 and Figure 4 In a preferred embodiment, the reset assembly includes a mounting block 6 arranged below the ejector body 2, the connecting block 5 and the mounting block 6 are arranged on the same horizontal plane, the cross section of the connecting block 5 is larger than the cross section of the mounting block 6, and by setting the reset assembly, when the spring frame 3 contracts to release the clamping formed on the object, the ejector body 2 can simultaneously release the positioning formed on the object.

[0028] Among them, refer to Figure 2 and Figure 4 In a preferred embodiment, the clamping assembly includes a clamping block 9 arranged inside the empty groove 14, a threaded groove is provided inside the clamping block 9, and a thread is provided on the outer wall of the connecting rod 10.

[0030] Working principle: When in use, when the staff operates the lathe, they manually push the spring frame 3 to shrink the spring frame 3 to the inside of the convex groove 15, and then extend the fixed plate 7 to the inside of the movable groove 11. A rack 12 is installed on one side of the movable groove 11, so that the rack 12 slides and drives the rotating gear 13 to rotate, so that the clamping block 9 threadedly connected to one end of the connecting rod 10 slides, and the object placed above the spring frame 3 is clamped and positioned, thereby increasing the stability of object processing. At the same time, when the connecting block 5 installed at one end of the spring frame 3 extends to the inside of the convex groove 15, the spring frame 3 can squeeze the mounting block 6, thereby driving the ejector body 2 fixedly connected to the mounting block 6 at the bottom to shrink, and when the spring frame 3 is reset, the ejector body 2 can be driven to reset at the same time.
