Detailed Description

The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

As shown in fig. 1, the special-shaped tool needle processing machine tool mainly comprises an xyz r four-axis fine adjustment sliding table 1, a grinding device 2, an imaging system 3, a feeding device 4, a clamping shaft 5, a belt transmission system 6 and a main motor 7. A feeding device 2 is arranged on the XYZR four-axis fine-tuning sliding table 1, a main motor 7 drives a belt transmission system 6 to rotate, and the belt transmission system 6 drives a clamping shaft 5 to rotate. The grinding device 2 is arranged at the opposite position of the clamping shaft 5, and the image system is arranged above the clamping shaft 5. The grinding device 2 mainly comprises an auxiliary motor 2.1, a grinding wheel 2.2 and a manual cross sliding table, wherein the auxiliary motor is installed on the manual cross sliding table, the grinding wheel 2.2 is coaxially installed on the auxiliary motor 2.1, and the auxiliary motor drives the grinding wheel to rotate.

As shown in fig. 2, the feeding device 4 is mainly composed of a guide rail 4.1, a slide 4.2, a chuck 4.3, a pressure rod 4.4 and a spring 4.5. The guide rail 4.1 is installed on XYZR four-axis fine setting slip table 1, and slide 4.2 is established to guide rail 4.1 assistance, and slide 4.2 installation chuck 4.3, chuck 4.3 are through round pin axle 4.6 connection depression bar 4.4, and depression bar 4.4 uses round pin axle 4.6 as the fulcrum and produces the swing. The head of the pressure lever 4.4 is provided with a folded plate 4.4a, and the inner side surface of the folded plate 4.4a covers the head end surface of the clamping head 4.3. The end face of the head of the chuck 4.3 is provided with a groove 4.3a for accommodating a tool needle.
