[0002] Metal cutting machine tools occupy an important position in the mechanical processing industry. The stability and accuracy of their positioning mechanism directly affect the quality of the workpiece. Traditional positioning mechanisms still have many problems. Therefore, it is particularly important to develop a positioning mechanism for mechanically manufactured metal cutting machine tools.

A fixing mechanism for positioning and clamping a workpiece is provided at the top of the positioning table. The fixing mechanism includes two limit baffles provided on a sliding position on the positioning table for clamping the workpiece. The opposite ends of the two limit baffles are provided with support plates for supporting the workpiece. This positioning mechanism facilitates the fixing and clamping of the workpiece through the two limit baffles, and the two support plates can support the workpiece, avoiding the situation where the cutting tool cuts the positioning table and damages it during the cutting process, affecting the next use, and can play a good protective role for the positioning table. The positioning plate at the end of the support plate can place one end of the workpiece against the positioning plate, so that the workpiece can be quickly positioned, which is convenient for cutting the workpiece. According to the above, although the positioning mechanism can be well applied, it is usually not convenient to adjust the spacing between the clamping components, and thus it is difficult to clamp and cut metal workpieces of different lengths, and has certain limitations.
