Detailed Description
To make the objects, technical solutions and advantages of the present invention more clearly understood by those skilled in the art, the present invention will be further described with reference to the accompanying drawings and examples, but the present invention is not limited to the following examples.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "disposed," "connected," and the like are to be construed broadly, and for example, "connected" may be either fixedly connected or detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in FIG. 1 and FIG. 2, the utility model provides a gear box turning clamp, including a mount pad 1, a location axle 2 and an adjusting part.
The mounting seat 1 is disc-shaped, the outer ring is clamped by a chuck of a lathe during machining, and the axis of the mounting seat 1 is collinear with the axes of the chuck and a lathe spindle. The centre of a circle department of mount pad 1 has seted up and has kept away sword hole 9, should keep away sword hole 9 and gear box 11 and wait the pore pair of processing, when carrying out spot facing work, keep away sword hole 9 and can dodge the lathe tool to make things convenient for the feed and the tool retracting of lathe tool, still seted up a through-hole on mount pad 1, this through-hole corresponds with the benchmark hole that gear box 11 has processed, and keep predetermined distance between the sword hole 9 with keeping away.
