Background technique

CNC machine tools are widely used in the machinery manufacturing industry. In order to meet various processing needs, a CNC machine tool is equipped with multiple sets of fixtures to meet various types of parts processing. When the workpiece is processed on the CNC machine tool, the workpiece is fixed on the worktable. After the fixture of the CNC machine tool finishes processing one type of workpiece, when another type of workpiece needs to be processed, the CNC machine tool starts to change the fixture, and then processes another type artifact. Generally, different fixtures need to be replaced after processing different workpieces, which is a waste of time. At present, the fixtures of CNC machine tools are installed on the workbench with screws or bolts. The installation is time-consuming and laborious, and the accuracy of the installation is difficult to guarantee, and it is inconvenient to replace.

Detailed ways

Referring to accompanying drawings 1 to 5 of the specification, a quick replacement device for a clamp body of a numerically controlled machine tool of the present invention will be described in detail below.

A quick replacement device for a clamp body of a CNC machine tool, comprising a CNC machine tool workbench 1, several sets of clamp bodies 2 provided with clamps 23, and a hydraulic cylinder 3; said CNC machine tool workbench 1 is provided with several inner conical holes 11 , the CNC machine tool workbench below the inner conical hole 11 is provided with a through hole 12, the diameter of the through hole 12 is less than the diameter of the bottom surface of the inner conical hole 11 and communicates with the inner conical hole; the bottom of the clamp body 2 is provided with The positioning platform 21 equal to the number of the inner conical hole, the positioning platform 21 is provided with the cone 22 matching the inner conical hole 11; The numbers are equal, the piston 31 of the hydraulic cylinder 3 is set in the through hole and matches the size of the through hole; the taper of the inner conical hole 11 and the cone 22 are all Morse tapers.

As shown in Figures 1 to 5, as a preferred solution, the CNC machine tool table 1 described in the present invention is provided with three inner conical holes 11, and the bottom of the clamp body 2 is provided with three positioning platforms 21, and the three positioning The cones 22 on the table correspond to the inner conical holes 11 on the workbench of the CNC machine tool respectively; the three conical holes 11 are respectively provided with through holes 12 below.

When installing and changing the clamp, directly press the three cones 22 of the clamp body 2 into the three inner cone holes 11 in the CNC machine table 1, and start the hydraulic cylinder 3 so that the piston 31 moves with the piston in the through hole. The rod moves downward, because the top and bottom of the three through holes in the CNC machine table 1 are sealed to form a vacuum, and the piston of the hydraulic cylinder 3 moves downward to generate a strong pulling force. Since the cone 22 of the clamp body 2 and the CNC machine table 3 adopt Morse taper, the reversible movement of the clamp body 2 is prevented, and the strong pulling force generated by the hydraulic cylinder can firmly fix the clamp body 2 on the CNC workbench 1 superior. When the clamp body 2 needs to be unloaded, the hydraulic cylinder 3 is opened to move the piston upward to push the clamp body 2 out of the CNC machine table 1.

The above descriptions are only specific implementations of the utility model, and changes that can be easily conceived by those skilled in the art within the scope of the disclosure of the utility model should be covered within the protection scope of the utility model. the
