[0007] The protective mechanism includes a protective cylinder slidably connected to the outer wall of the main shaft body. A take-up shaft is rotatably connected inside the protective cylinder and to the front, back, top, and bottom of the main shaft body. A protective pad is wound around the outer wall of the take-up shaft inside the protective cylinder. An installation ring is fixedly connected to the outer wall of the protective pad and to the left side of the protective cylinder. A clamping block is slidably connected inside the protective cylinder and to the right side of the take-up shaft. A fixing sleeve is slidably connected to the outer wall of the clamping block and to the protective cylinder. A sealing ring is fixedly connected to the inner wall of the protective cylinder and to the right side of the clamping block. A return spring is fixedly connected to the outer wall of the clamping block and to the fixing sleeve. A piston plate is slidably connected inside the fixing sleeve at a position away from the clamping block. A push rod is fixedly connected to the outer wall of the piston plate and to the fixing sleeve. An internal threaded ring is rotatably connected to the outer wall of the push rod. A spiral spring is fixedly connected to the outer wall of the take-up shaft near the protective pad.

[0008] As a preferred embodiment of this utility model, the limiting ring is provided in multiple sets, and the limiting ring is designed with a concave shape.

[0009] As a preferred embodiment of this utility model, the protective cylinder, mounting ring, clamping block, fixing sleeve, and pushing rod are all made of aluminum alloy. The fixing sleeve and pushing rod are both L-shaped structures. The reset spring is fixedly connected to the fixing sleeve, and the spiral spring is fixedly connected to the protective cylinder.

[0010] As a preferred embodiment of this utility model, the internal threaded ring and the piston plate are both made of ABS plastic, and multiple sets of the clamping block, the fixing sleeve, the piston plate and the push rod are provided. The push rod and the fixing sleeve are connected by a sliding connection.

[0011] As a preferred embodiment of this utility model, the push rod passes through the fixed sleeve and extends to the outside of the protective sleeve, and the connection between the internal threaded ring and the protective sleeve is a threaded connection.

[0012] As a preferred embodiment of this utility model, the protective pad is made of nylon fiber weaving, and the protective pad extends through and beyond the protective cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, a protective mechanism is designed for a machine tool spindle to prevent debris from adhering to the spindle. The protective sleeve is removed from the spindle body, the spindle body is installed inside the machine tool, and the protective sleeve is then placed on the spindle body. The mounting ring is fixed to the outer wall of the machine tool with bolts. Pulling the protective sleeve causes it to slide along the spindle body, pulling out the protective pad wound on the take-up shaft. The pulled-out protective pad covers the spindle body. When the clamping block inside the sliding protective sleeve aligns with the limiting ring, the movement of the protective sleeve stops. The internal threaded ring is rotated, and the rotating internal threaded ring drives the piston plate to move through the push rod. The moving piston plate pushes the clamping block outward through the air in the fixed sleeve. The outwardly moving clamping block inserts into the limiting ring, and the clamping block installs the protective sleeve on the spindle body. This prevents debris from adhering to the spindle body and solves the problem that existing spindles are prone to having debris generated by external processing adhere to the spindle during operation, affecting the normal operation of the spindle.
