Detailed Description

The utility model will be described in further detail with reference to the drawings and the detailed description.

Examples: as shown in fig. 1-4, in this embodiment, a gear machining installation fixture is provided, which includes an upper fixture structure 1 and a lower fixture structure 2, wherein the upper fixture structure includes an upper fixture body 11 and an upper pressing ring 12 disposed below the upper fixture body, the lower fixture structure includes a lower fixture body 21 and a lower pressing ring 22 disposed above the lower fixture body, and a clamping space for limiting a gear to be machined is formed between the upper and lower pressing rings.

In this embodiment, the top of the lower fixture body is provided with a fixing shaft 23 extending upwards out of the upper pressing ring and used for passing through the gear to be processed, and the bottom of the upper fixture body is provided with a notch 13 into which the fixing shaft extends.

In this embodiment, in order to better limit the gear, the lower surface of the upper pressing ring and the upper surface of the lower pressing ring are provided with convex strips 3.

In this embodiment, the inside fixed orifices that is used for installing the fixed axle that is equipped with of lower anchor clamps body, all be provided with compression spring between fixed axle lower extreme and fixed orifices inner bottom surface, fixed axle upper end and the notch inner top surface for realize that the fixed axle is flexible up and down.

In this embodiment, the fixed shaft includes an upper shaft 231 and a lower shaft 231, the diameter of the upper shaft is smaller than that of the lower shaft, and a step surface for supporting a gear to be processed is formed at the connection of the upper shaft and the lower shaft.

In the embodiment, the gear 4 to be processed passes through the fixed shaft, and then the fixed shaft of the lower clamp body passes into the notch of the upper clamp body, so that the upper clamp structure and the lower clamp structure are connected into a whole to form a gear installation clamp; the gear mounting fixture is arranged on the gear machining equipment, the gear machining equipment can apply positioning pressure to the upper fixture, the fixed shaft moves downwards under the action of the pressure, the lower end face of the gear is in contact with the lower pressing disc, the upper pressing ring moves downwards to be in contact with the upper end face of the gear, and accordingly the upper pressing ring and the lower pressing ring move to press the gear to be machined, and machining tools of the gear machining equipment can be used for machining the outer peripheral face of the gear.
