Two-shaft numerical control device used for machining shoe molds

Abstract

The invention discloses a two-shaft numerical control device used for processing shoe molds. The device comprises a base (1), a horizontal shaft (2) and a vertical shaft (3). The horizontal shaft is composed of a support, a rotating base, a speed reducer P and a servo motor P. The vertical shaft is composed of a speed reducer Z, a servo motor Z and a rotating table. The support and the speed reducer P are fixed to the upper surface of the base. The rotating base is rotationally connected between the support and the speed reducer P. The speed reducer Z and the servo motor Z are located on the rotating base. The output end of the speed reducer Z faces upwards. The rotating table is connected with the output end of the speed reducer Z. During application, the servo motor P drives the rotating base to rotate around the horizontal axis through the speed reducer P. The servo motor Z drives the rotating table to rotate around the vertical shaft through the speed reducer Z. The rotating table bears shoe mold blanks and is matched with a cutting tool of a numerical control carving and milling machine tool for processing. Through the technical scheme, the overall shoe mold carving and milling process can be completed through one time of clamping, and the purposes of improving efficiency, precision and quality and reducing cost are achieved during processing of the shoe molds.

Description

technical field [0001] The invention relates to an auxiliary device of a metal cutting machine tool, in particular to a two-axis numerical control device for processing a shoe mold which carries a shoe mold blank and carries out a two-axis numerical control movement when a numerical control engraving and milling machine tool processes a shoe sole model. Background technique [0002] The existing technology can use the five-axis machining center to process the shoe sole model, because the investment of the five-axis machining center is high, the processing cost is expensive, and the cost is too high. Therefore, CNC engraving and milling machine tools are usually used to process shoe molds; Engraving and milling process five surfaces including top, left side, right side, front side, and back side, and it needs to go through rough milling, fine milling, and engraving processes. Each process needs to rotate and exchange the processing surface of the model, usually by Manual clam...

[0002] The existing technology can use the five-axis machining center to process the shoe sole model, because the investment of the five-axis machining center is high, the processing cost is expensive, and the cost is too high. Therefore, CNC engraving and milling machine tools are usually used to process shoe molds; Engraving and milling process five surfaces including top, left side, right side, front side, and back side, and it needs to go through rough milling, fine milling, and engraving processes. Each process needs to rotate and exchange the processing surface of the model, usually by Manual clamping is used to change the processing surface, and each clamping of each process needs to be re-aligned and calibrated to the reference plane and the initial zero point, so the efficiency is low, the accuracy is poor, and defective products are easily produced, and the labor cost is high; the existing The technology also adopts an automatic device for automatic face-changing rotation. For example, a Chinese patent, an automatic face-changing device for engraving and processing shoe molds 201110334951.9; , Front and rear four sides are automatically changed and rotated, and the surface cannot be automatically changed from the top to the side of the shoe mold. When the top of the shoe mold is processed and transferred to the side of the shoe mold, it is still necessary to manually clamp and replace it. Although the machined surface is superior to manual surface replacement, it still has high efficiency and low cost; therefore, the existing technology has problems and deficiencies such as low efficiency, poor precision, poor quality, and high cost
