The part clamping device 1 for a numerically controlled machine tool 2 of the present utility model includes a fixture base 11, a first V-shaped fixing plate 12, a second V-shaped fixing plate 1313, a first V-shaped movable plate 14, a second V-shaped movable plate 15, and a clamping driving member 1616. The first V-shaped fixing plate 12 and the second V-shaped fixing plate 13 are both fixed on the fixture base 11, and the V-shaped fixing plate and the second V-shaped fixing plate 13 are respectively located on both sides of the clamping driving member 16. The first V-shaped movable plate 14 and the second V-shaped movable plate 15 are respectively installed on both sides of the clamping driving member 16, and the open ends of the first V-shaped fixing plate 12 and the first V-shaped movable plate 14 are arranged opposite to each other. The open ends of the second V-shaped fixing plate 13 and the second V-shaped movable plate 15 are arranged opposite to each other. The clamping driving member 16 can simultaneously drive the first V-shaped movable plate 14 and the second V-shaped movable plate 15 to extend or retract.
[0023] When using the part clamping device 1 to clamp a part, first control the clamping driving member 16 to drive the first V-shaped movable plate 14 and the second V-shaped movable plate 15 to retract, so that the distance between the first V-shaped movable plate 14 and the first V-shaped fixing plate 12 increases, and the distance between the second V-shaped movable plate 15 and the second V-shaped fixing plate 13 increases. Thus, it is convenient for the operator to place a part between the first V-shaped movable plate 14 and the first V-shaped fixing plate 12, and place a part between the second V-shaped movable plate 15 and the second V-shaped fixing plate 13. Subsequently, control the clamping driving member 16 to drive the first V-shaped movable plate 14 and the second V-shaped movable plate 15 to extend, so that the distance between the first V-shaped movable plate 14 and the first V-shaped fixing plate 12 decreases, and the distance between the second V-shaped movable plate 15 and the second V-shaped fixing plate 13 decreases. Then, the first V-shaped movable plate 14 and the first V-shaped fixing plate 12 jointly clamp a part, and the second V-shaped movable plate 15 and the second V-shaped fixing plate 13 jointly clamp a part, so that the part clamping device 1 simultaneously clamps and fixes two parts of the same batch, facilitating the numerically controlled machine tool 2 to process two parts at one time, improving the operation efficiency, and there is no need to manually adjust the part clamping device 1 during the clamping process, improving the clamping efficiency of the parts and reducing the operation intensity of the operator.
[0024] By setting the first V-shaped fixing plate 12, the second V-shaped fixing plate 13, the first V-shaped movable plate 14, and the second V-shaped movable plate 15 as V-shaped, it is convenient for the first V-shaped fixing plate 12 and the first V-shaped movable plate 14 with opposite open ends to clamp the part when moving relative to each other. Similarly, it is convenient for the second V-shaped fixing plate 13 and the second V-shaped movable plate 15 with opposite open ends to clamp the part when moving relative to each other, improving the clamping stability of the part and avoiding the problem of part movement or detachment during subsequent processing of the part.
[0025] In an embodiment of the present utility model, the clamping driving member 16 is a double-headed cylinder, and cylinder output shafts are arranged on both sides of the double-headed cylinder. The first V-shaped movable plate 14 and the second V-shaped movable plate 15 are respectively connected to the cylinder output shafts on both sides of the double-headed cylinder.
[0026] By setting the clamping driving member 16 as a double-headed cylinder, it is convenient for the first V-shaped movable plate 14 and the second V-shaped movable plate 15 to be respectively connected to the output shafts on both sides of the double-headed cylinder. Then, when the double-headed cylinder works, the output shafts on both sides extend or retract simultaneously, thereby driving the first V-shaped movable plate 14 and the second V-shaped movable plate 15 to extend or retract simultaneously, realizing the rapid clamping and releasing of parts. Using a double-headed cylinder as the clamping driving member 16 simplifies the structure of the part clamping device 1, and at the same time ensures the synchronous movement of the V-shaped movable plates on both sides, improving the stability and response speed of clamping.
[0027] In other embodiments of the present utility model, the clamping driving member 16 is a double-shaft motor, and motor output shafts are arranged on both sides of the double-shaft motor. The part clamping device 1 further includes a first screw rod and a second screw rod. The first screw rod and the second screw rod are respectively connected to the two motor output shafts. The thread directions of the first screw rod and the second screw rod are opposite, and the first V-shaped movable plate 14 and the second V-shaped movable plate 15 are respectively threadedly connected to the first screw rod and the second screw rod.
[0028] By setting the clamping driving member 16 as a double-shaft motor and connecting the first screw rod and the second screw rod to the output shafts on both sides of the double-shaft motor respectively, so that the first V-shaped movable plate 14 and the second V-shaped movable plate 15 are respectively threadedly connected to the first screw rod and the second screw rod. Then, when the double-shaft motor works, the output shafts on both sides drive the first screw rod and the second screw rod to rotate synchronously. Since the thread directions of the first screw rod and the second screw rod are opposite, the first screw rod and the second screw rod can respectively drive the first V-shaped movable plate 14 and the second V-shaped movable plate 15 to move along the screw rods, that is, drive the first V-shaped movable plate 14 and the second V-shaped movable plate 15 to extend or retract simultaneously, realizing the rapid clamping and releasing of parts, and thus realizing the clamping or releasing of parts.

When clamping small-sized parts, by inserting the V-shaped cushion plate 17 into the first V-shaped fixed plate 12 and the first V-shaped movable plate 14 respectively, the distance between the first V-shaped fixed plate 12 and the first V-shaped movable plate 14 is reduced, thereby realizing the clamping effect on small-sized parts. Similarly, by inserting the V-shaped cushion plate 17 into the second V-shaped fixed plate 13 and the second V-shaped movable plate 15 respectively, the distance between the second V-shaped fixed plate 13 and the second V-shaped movable plate 15 is reduced, thereby realizing the clamping effect on small-sized parts, enabling the part clamping device 1 to have the function of fine-tuning the clamping pressure and being applicable to parts of different sizes and shapes.

[0033] When installing the part clamping device 1 on the numerical control machine tool 2, by inserting the locking rod 18 into the T-shaped groove on the T-shaped workbench 21, then rotating the connecting rod 19 to make the locking rod 18 clamped in the T-shaped groove, and finally tightening the connecting sleeve 10, the part clamping device 1 can be fixed on the T-shaped workbench 21, facilitating the operator to use the part clamping device 1 for part clamping operations and improving the part clamping efficiency and part processing efficiency.

By connecting the adapter to the top of the connecting rod 19, the connecting rod 19 can be rotated on the clamp base 11, and then the rotating connecting rod 19 drives the locking rod 18 to rotate, so that the locking rod 18 can adjust the angle. When the locking rod 18 is in the T-slot and consistent with the direction of the T-slot, the part clamping device 1 can be easily removed from the T-shaped workbench 21. When the locking rod 18 is in the T-slot and perpendicular to the direction of the T-slot, the part clamping device 1 can be fixed on the T-shaped workbench 21 by pressing the adjusting rod.
