Description

Technical Field

[0001] The utility model belongs to the field of numerically controlled machine tools, and in particular relates to a clamp fixing mechanism of a numerically controlled machine tool. Background Art

[0002] The chuck is a mechanical device used to clamp the workpiece on the machine tool. It is a machine tool accessory that clamps and positions the workpiece by radial movement of the movable jaws evenly distributed on the chuck body.

[0003] The patent application with publication number CN219074922U discloses a fixture fixing mechanism for a CNC machine tool, including: a chuck body, an annular plate, one end of the chuck body is elastically and slidably matched with four arc plates, and the four arc plates are arranged in an array, and the inner side walls of the arc plates are evenly equipped with multiple rubber protrusions, which is convenient for increasing the friction between the workpiece and the arc plate through the rubber protrusions; and the annular plate is elastically and slidably matched on the outer side wall of the chuck body. The utility model uses the arc plate to enable the rotating plate to drive the four arc plates at the same time under the drive of the annular plate, so that the workpiece placed at one end of the chuck body can be positioned and released. On the one hand, it improves the process of disassembling and assembling the workpiece, and on the other hand, it is convenient to adjust the position of the arc plate at the same time, which improves the practicality of the arc plate in positioning the workpiece.

[0004] However, the above technology has the following disadvantages when used:

[0005] It is described in paragraph 0022 of the above document that "when it is necessary to clamp the workpiece, first slide the annular plate 2, the annular plate 2 drives the sliding rod 103 to slide inside the fixed cylinder 102 and stretch the first spring 104, the annular plate 2 drives the arc plate 107 to slide on the guide rod 105 and compress the second spring 110 through the rotating plate 203, and then place the workpiece on one end of the chuck body 1, and then release the annular plate 2, the annular plate 2 is reset under the elastic action of the first spring 104". It can be seen that the arc plate 107 needs to slide in the axial direction of the guide rod 105, and because the rotating plate 203 drives the arc plate 107 to slide, it will increase the labor of the arc plate 107 when sliding, and increase the cost of the arc plate 107 when in use.

[0006] Therefore, a fixture fixing mechanism for a CNC machine tool is proposed to solve the above-mentioned drawbacks. Utility Model Content
