Technical Field
[0001] This utility model relates to the field of milling cutter processing technology, specifically a transfer and clamping mechanism for T-type milling cutter processing. Background Technology
[0002] Milling cutters are machining tools used on milling machines to process planes, steps, grooves, shaped surfaces, and cut off workpieces. In order to ensure machining efficiency and safety, a transfer and clamping mechanism is needed to transfer and pick up the workpiece to be machined and the machined workpiece during the milling process.
[0003] Among the existing technologies, the transfer and clamping mechanism for milling cutter machining proposed in the patent announcement number CN214393416U includes a frame, a mounting base, and clamping components. The mounting base is slidably engaged with the frame. The frame is provided with a sliding component that drives the mounting base to slide horizontally. There are two clamping components, both of which are mounted on the mounting base. The mounting base is provided with a rotating component that drives the two clamping components to rotate and change position. The mounting base is provided with a lifting component that drives the two clamping components to move vertically.
[0004] In existing technologies, the devices cannot accurately determine the position and path of the fixture movement during use, and cannot accurately position and clamp the milling cutter material quickly. We propose a transfer and clamping mechanism for T-shaped milling cutter machining. Utility Model Content
