Detailed Description

In order to make the technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

The utility model provides a large-scale milling machine fixture, as shown in fig. 1 to 3, fig. 1 is a schematic view of the overall structure of the large-scale milling machine fixture in the embodiment, which comprises a workbench 1, two positioning rods 2 are symmetrically arranged on the table top of the workbench 1, a pressing plate 3 is connected on the positioning rods 2 in a sliding manner, a U-shaped chute 4 is arranged on the pressing plate 3, so that the pressing plate 3 can move on the positioning rods 2 in a single direction, an elastic column 5 is arranged at the other end of the positioning rod 2, the elastic column 5 is contacted with the bottom end of the pressing plate 3, and a groove 9 for the elastic column 5 to use is arranged at the bottom end of the pressing plate 3; the middle parts of the two clamping plates 3 are provided with disc grooves 6, the inner parts of the disc grooves 6 are rotatably connected with rotating discs 7, the side surface of the workbench 1 is also provided with a hand wheel 8, and the hand wheel 8 can control the rotating discs 7 to rotate.

Fig. 2 is an exploded view of a large milling jig according to an embodiment, in which a bearing 11 is engaged with a disc groove 6, a first rotating shaft 12 is engaged with the inside of the bearing 11 and is connected to the first rotating shaft by a locking key so that the first rotating shaft and the first rotating shaft do not rotate relative to each other, and a spring 13 is fixedly connected to a bottom end of the first rotating shaft 12.
