Specifically, the material conveying drive module 12 includes a lead screw and a motor, with the lead screw arranged along the Y-axis. The material tray 11 has several material holes, and the workpiece can be vertically inserted into the material holes for placement. Further, the several material holes are arranged in an array.

[0035] In addition, the high-frequency quenching automated equipment provided by this utility model also includes a frame, a material conveying device 1, a high-frequency quenching device 2, and a transfer device 3, which are mounted on the frame.

[0036] The first clamping arm 311 has a first V-shaped tooth on its inner sidewall, with the V-shaped opening facing the second clamping arm 312. The second clamping arm 312 has two second V-shaped teeth arranged vertically on its inner sidewall, with the V-shaped opening facing the first clamping arm 311.

[0037] The inner sidewall of the first clamping arm 311 is also provided with a third V-shaped tooth, and the third V-shaped tooth is located at the bottom of the first V-shaped tooth; the V-shaped opening of the third V-shaped tooth faces the second clamping arm 312, and the third V-shaped tooth can be embedded in the V-shaped opening of the lower second V-shaped tooth. By providing the third V-shaped tooth, a structure surrounding the workpiece is formed between the third V-shaped tooth and the V-shaped opening of the lower second V-shaped tooth, thereby enhancing the clamping force.

[0038] The high-frequency quenching device 2 includes a high-frequency heating machine 21, a heating coil 22 electrically connected to the high-frequency heating machine 21, and a coil adjustment module 23 connected to the heating coil 22.
