[0002] A drilling machine mainly refers to a machine tool for machining holes in workpieces with a drill bit. Usually, the rotation of the drill bit is the main movement, and the axial movement of the drill bit is the feed movement. The drilling machine has a simple structure and relatively low machining accuracy. It can drill through holes and blind holes. By replacing special tools, it can perform operations such as reaming, countersinking, boring, or tapping. During the machining process, the workpiece remains stationary while the tool moves. The center of the tool is aligned with the center of the hole, and the tool rotates (main movement). The characteristic of the drilling machine is that the workpiece is fixed and the tool rotates.

[0003] During the clamping process of the existing drilling machine, manual loading and unloading are usually adopted. However, in this process, human labor is increased, there are safety risks, and the efficiency is low. Therefore, an automatic material clamping device is proposed for the above problems.

One side of the jaw device base is fixedly connected with a fixed jaw. One side of the jaw device base is movably connected with a movable jaw. The middle part of the movable jaw is hinged to the middle part of the fixed jaw. One side of the jaw device base is fixedly connected with a guide seat. One side of the guide seat is fixedly connected with a cylinder. The side of the guide seat away from the cylinder is movably connected with a movable inclined top locking block. The output end of the cylinder is fixedly connected with one end of the movable inclined top locking block. A spring is fixedly connected inside the fixed jaw, and the spring is fixedly connected with the fixed jaw. A workpiece to be measured is arranged on one side of the jaw device base.

[0006] Preferably, one side of the jaw device base is fixedly connected with a fixed pressing plate, and the fixed jaw is fixedly connected to the jaw device base through the fixed pressing plate.
