Specific embodiments

[0024] In order to further understand the content, features and effects of the present utility model, the following embodiments are exemplified and described in detail with reference to the accompanying drawings.

[0025] Please refer to Figures 1 to 3 simultaneously. The following will describe in detail the quick clamping device for a wire cutting machine tool according to an embodiment of the present utility model with reference to the accompanying drawings.

[0026] As Figure 1 shown, the quick clamping device for a wire cutting machine tool includes a wire cutting machine tool body, a workbench 1 installed inside the wire cutting machine tool body, a vertical rod 2 and a cross bar 3 slidably connected to the vertical rod 2 installed inside the workbench 1. A sliding base 4 is slidably connected to the cross bar 3. A fixed block 5 is fixed to the upper end of the sliding base 4. A clamping block 6 is rotatably connected inside the fixed block 5. A plurality of through holes 7 are equidistantly arranged on the cross bar 3. A limit screw 8 is threadedly connected to the sliding base 4. The screwing end of the limit screw 8 can pass through the through hole 7 to fix the sliding base 4. There are two sliding bases 4 on the cross bar 3, and the positions of the two sliding bases 4 can be freely adjusted. After adjustment, by screwing the limit screw 8 and inserting the screwing end of the limit screw 8 into the through hole 7, the sliding base 4 can be fixed.

[0027] Among them, as Figure 3 shown, the clamping block 6 includes an L-shaped fixing plate 9, a detachable plate 10 screwed to one end of the L-shaped fixing plate 9, and further includes an adjusting screw 11 threadedly connected inside the L-shaped fixing plate 9. An abutting plate 12 is movably connected to the end of the adjusting screw 11 facing the detachable plate 10. A spherical connecting block 13 is fixed to the upper end of the abutting plate 12. A spherical movable block 14 is rotatably connected inside the spherical connecting block 13. The end of the spherical movable block 14 away from the spherical connecting block 13 is fixed to the adjusting screw 11.

[0028] One end of the L-shaped fixing plate 9 is fixed with a rotating shaft 15. The rotating shaft 15 is rotatably connected inside the fixed block 5. The end away from the L-shaped fixing plate 9 extends out of the fixed block 5, and the extending end is connected with a servo motor 16. The servo motor 16 is fixed to the fixed block 5 by screws.

[0029] The servo motor 16 can drive the rotating shaft 15 to rotate. At the same time, the rotating shaft 15 is fixedly connected to the L-shaped fixing plate 9. When the rotating shaft 15 rotates, it can drive the L-shaped fixing plate 9 to rotate. Furthermore, the L-shaped fixing plate 9 can be adjusted to a horizontal state or a vertical state according to requirements.

[0030] Specifically, for the cutting of annular parts, the L-shaped fixing plate 9 is adjusted to a vertical state. The detachable plate 10 is abutted against the outer wall of the part, and the abutting plate 12 is abutted against the inner wall of the part. At the same time, since the inner wall of the part is an arc structure, it is necessary for the abutting plate 12 to better fit against the inner wall of the part. Therefore, the abutting plate 12 and the adjusting screw 11 are movably connected. After the abutting plate 12 abuts against the inner wall of the part, the spherical connecting block 13 at the upper end of the abutting plate 12 rotates with the spherical movable block 14, so that the abutting plate 12 can better fit against the inner wall of the part. For the cutting of plate-shaped parts, when the L-shaped fixing plate 9 is in a vertical state, the plate-shaped part is placed inside the two L-shaped fixing plates 9, and by rotating the adjusting screw 11, the abutting plate 12 and the detachable plate 10 are respectively placed on both sides of the part.

[0031] For columnar parts, the side wall of the part needs to be fixed. At this time, the servo motor 16 can be turned on to drive the L-shaped fixing plate 9 to rotate. After the L-shaped fixing plate 9 is rotated to a horizontal state, the detachable plate 10 is removed. At this time, the abutting plates 12 inside the two L-shaped fixing plates 9 are arranged oppositely. Then, according to the size of the part, the positions of the two sliding bases 4 are adjusted. After the two sliding bases 4 are fixed, the adjusting screw 11 is rotated to adjust the positions of the two abutting plates 12 so that the two abutting plates 12 respectively abut against the two side walls of the part. At the same time, the side of the abutting plate 12 facing the part is arc-shaped, so the part can be better locked.

[0032] Furthermore, an anti-slip block 17 is adhered to the abutting plate 12, which can increase the friction when clamping the part. The anti-slip block 17 in this embodiment is made of rubber material.

[0033] In order to more conveniently disassemble the sliding base 4 and prevent the sliding base 4 from slipping off, a C-shaped plate 18 is fixed to the end of the sliding base 4 away from the fixed block 5 by screws. The C-shaped plate 18 and the sliding base 4 are in a covering state and cover the outside of the cross bar 3.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
