[0019] 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.

[0020] Please see Figures 1-4This utility model provides a technical solution: a heavy-duty built-in spindle type lathe tailstock, including a base 1 and an adjusting seat 2. The adjusting seat 2 is provided on the top of the base 1, and a support block 3 is provided on the top of the adjusting seat 2. A housing 4 is provided on the top of the support block 3. The housing 4 and the support block 3 are fixedly connected. A threaded sleeve 5 is provided inside the housing 4. The threaded sleeve 5 and the housing 4 are rotatably connected. A threaded rod 6 is provided inside the threaded sleeve 5. The threaded rod 6 and the threaded sleeve 5 are connected by threads. A first motor 7 is provided at one end of the housing 4. The first motor 7 and the housing 4 are fixed by screws. A limiting groove 8 is embedded on the top of the threaded rod 6. A limiting plate 9 is provided inside the limiting groove 8. The limiting plate 9 and the limiting groove 8 are slidably connected.

[0021] In this embodiment, when using the tailstock of the heavy-duty built-in spindle lathe, the first motor 7 is started, which drives the threaded sleeve 5 to rotate, thereby causing the threaded rod 6 to extend and retract inside the threaded sleeve 5, and then driving the drill bit 11 to drill the workpiece. No manual drilling is required, saving time and effort and effectively improving work efficiency. The limiting groove 8 and the limiting plate 9 can limit the threaded rod 6. When the threaded rod 6 moves, the limiting plate 9 will slide inside the limiting groove 8 to prevent it from rotating, effectively improving stability.

[0022] Specifically, a second motor 10 is provided at one end of the threaded rod 6, and the second motor 10 and the threaded rod 6 are detachably connected. A drill bit 11 is provided at the output end of the second motor 10. A sliding groove 12 is embedded in the top of the base 1. A slider 13 is provided at the bottom of the adjusting seat 2. The slider 13 and the sliding groove 12 are slidably connected. An adjusting block 14 is provided at the bottom of the adjusting seat 2.
