[0020] A convenient tool unloading mechanism for radial drilling machines is disclosed, relating to the field of machine tool technology. It primarily addresses the problem of inconvenient tool unloading operations in existing technologies. The composition and working principle of this tool unloading mechanism are described in detail below.

[0021] Referring to Figures 3 and 4, the radial drilling machine has a spindle 1 and a spindle box 8, with an elongated hole 1.1 on the spindle 1. The tool unloading mechanism includes a hinge shaft 2 and a locking pin 6 disposed within the elongated hole 1.1. The hinge shaft 2 is horizontally positioned, and the locking pin 6 is vertically fixed to the top of the elongated hole 1.1. A rotating arm 3 is hinged to the hinge shaft 2, and a torsion spring 4 is disposed between the rotating arm 3 and the spindle 1. The torsion spring 4 applies a rotational torque to the rotating arm 3, causing it to rotate counterclockwise.

[0022] Referring to Figure 5, a groove 3.1 is provided inside the rotating arm 3, and the cross-sectional shape of the groove 3.1 is rectangular. To facilitate finger pressing of the rotating arm 3, an acupressure plate 3.2 is provided at the lower part of the free end of the rotating arm 3.

[0023] Referring again to Figure 4, a compression spring 7 and a sliding post 5 are installed within the slide groove 3.1. The sliding post 5 is a long rectangular column that can slide within the slide groove 3.1. To limit the sliding stroke, a stepped sliding stroke limiting structure is provided between the slide groove 3.1 and the sliding post 5. The compression spring 7 is located at the left end of the slide groove 3.1, and its function is to apply a rightward pushing force to the sliding post 5. A locking groove 5.1 corresponding to the locking pin 6 is provided on the sliding post 5. Due to the obstruction of the locking pin 6, the sliding post 5 is stuck within the slide groove 3.1 and cannot slide to the right.

[0024] In addition, a shock-proof ring 9 is installed at the lower end of the spindle box 8. The function of the shock-proof ring 9 is to prevent the spindle box 8 from being bumped or knocked.

[0025] Working principle:

[0026] As shown in Figure 4, the rotating arm 3 rests against the upper part of the elongated hole 1.1 under the action of the torsion spring 4. The sliding pin 5 is blocked by the locking pin 6 and is locked within the sliding groove 3.1. In this way, both the rotating arm 3 and the sliding pin 5 are hidden within the elongated hole 1.1, and will not affect the movement of the spindle 1.

[0027] Referring to Figure 6, when the tool needs to be removed, press down on the acupressure plate 3.2 with your finger to rotate the rotating arm 3 clockwise. At this time, the locking groove 5.1 disengages from the blocking pin 6, and the sliding column 5 slides to the right and extends outward to the outside of the main shaft 1. Because a sliding stroke limiting structure is provided between the sliding groove 3.1 and the sliding column 5, the sliding column 5 will not completely slide out of the sliding groove 3.1.

[0028] Referring to Figure 7, crank the handwheel to move the spindle 1 upwards, at which point the slide 5 collides with the anti-collision ring 9. Simultaneously, the slide 5 rotates clockwise, applying downward pressure to the tool holder 10, forcing the tool out of the spindle 1 hole, thus unloading the tool.

[0029] Refer to Figure 8. After the tool is removed, the rotating arm 3 rotates counterclockwise under the action of the torsion spring 4. At this time, press the sliding pin 5 to the left to make the locking pin 6 lock in the locking groove 5.1, and re-lock the sliding pin 5 in the sliding groove 3.1.

[0030] In summary, this tool unloading mechanism is integrated into the elongated hole 1.1 of the spindle 1, and tool unloading can be achieved simply by pressing with a finger and moving the spindle 1 upwards. Compared with the prior art, this tool unloading mechanism does not require wedges and hammers, and is characterized by its convenient operation and ease of use.

[0031] It is worth noting that the content not described in detail in the above embodiments is prior art. It is also worth noting that any additions, subtractions, substitutions, and improvements made by those skilled in the art based on the structure and principles of this utility model should be included within the protection scope of this utility model.
