Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments of the present invention belong to the protection scope of the present invention.
As shown in fig. 1-2, a machining clamping tool comprises a three-jaw chuck 1, a square upright column 3 is vertically arranged at the outer end of each jaw 2 of the three-jaw chuck 1, the outer end of each jaw 2 is perpendicular to the disc surface of the three-jaw chuck 1, a sliding groove 31 is formed in the side surface of each upright column 3, which is close to the inner end of each jaw 2, a lifting sheet 4 is connected to the sliding groove 31 in a sliding manner, the sliding direction of each lifting sheet 4 is parallel to the axis of the three-jaw chuck 1, a threaded rod 5 is rotatably connected in the sliding groove 31, the axis of each threaded rod 5 is parallel to the axis of the three-jaw chuck 1, and the threaded rod 5 is in threaded connection with the lifting sheet 4.
In actual use, the threaded rod 5 is rotated according to the thickness of a workpiece, the positions of the lifting pieces 4 are adjusted, the workpiece is placed on the three lifting pieces 4 and abutted tightly, then the clamping jaws 2 are moved, the three upright posts 3 abut tightly against the workpiece, and clamping of the workpiece is completed.
In this embodiment, the chute 31 is an inverted T-shaped chute 31, and the shape of the end of the lifting piece 4 is matched with the chute 31, so that the structure is reasonable, and the lifting piece 4 is more stably connected with the upright post 3.
In this embodiment, the side surfaces of the column 3 on both sides of the opening of the chute 31 are arc-shaped surfaces, so as to improve the smoothness of the contact between the column 3 and the workpiece.
In this embodiment, the scale 32 is marked on one side surface of the upright post 3, so that the position of the lifting piece 4 can be quickly positioned according to the scale 32, and the time for adjusting the lifting piece 4 is reduced.
In this embodiment, spout 31 link up stand 3 and keep away from the tip of jack catch 2, stand 3 keeps away from fixed welding on the tip of jack catch 2 has fixed plate 6, jack 21 has been seted up to the outer end of jack catch 2, threaded rod 5 link up fixed plate 6 and insert locate in jack 21, threaded rod 5 rotates with fixed plate 6 to be connected, the welding has spacing piece 51 on threaded rod 5, spacing piece 51 is close to the side sliding connection of jack catch 2 with the fixed plate, and is rational in infrastructure, the firm installation threaded rod 5 of being convenient for.
