Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, detailed description of the invention of the present utility model is described in further detail, object is that help those skilled in the art conceives utility model of the present utility model, technical scheme has more complete, accurate and deep understanding, and contributes to its enforcement.
As shown in Figures 1 to 4, a kind of shaft-like workpiece processing of the utility model alignment device, for workpiece 3 carrying out centering, accurately to determine the Working position of keyway during milling circumference angle keyway at workpiece 3 on lathe.This alignment device comprises the body 1 for entangling workpiece 3, the outer surface of body 1 is provided with and parallels with the axis of workpiece 3 and centering plane for determining workpiece 3 Working position, centering plane is also circumferentially at least provided with two, with workpiece 3 needs the number of the keyway processed equal, an each centering plane keyway Working position respectively on corresponding workpiece 3.
To workpiece 3 as shown in Figure 1, two keyways need be processed respectively at the two ends of workpiece 3, be respectively the first keyway 31 and the angle between the second keyway 32, first keyway 31 and the second keyway 32 is 120 degree.
Specifically, the body 1 of this alignment device is cirque structure, and body 1 center is provided with the centre bore 13 allowing workpiece 3 pass, and this centre bore 13 is circular hole.
The outer surface of body 1 is provided with two centering planes, and being respectively the first centering plane 11 and the second centering plane 12, first centering plane 11 and the second centering plane 12 is extend to the other end from one end of body 1.First centering plane 11 and the second centering plane 12 all parallel with the axis of body 1, and the normal of the first centering plane 11 and the second centering plane 12 is all through the center of circle of centre bore 13.
As shown in Figures 2 and 3, corresponding with the angle angle of the first keyway 31 on workpiece 3 and the second keyway 32, the first centering plane 11 on body 1 and the angle between the normal of the second centering plane 12 are 120 degree, and the angle namely between the first centering plane 11 and the second centering plane 12 is 120 degree.
As depicted in figs. 1 and 2, body 1 is circumferentially provided with several holding screws 2, holding screw 2 stretches out in centre bore 13 through the screwed hole that body 1 is arranged, and holding screw 2 and body 1 are for being threaded.
As preferably, holding screw 2 is circumferentially evenly equipped with three on body 1, and wherein two holding screws 2 lay respectively at the first centering plane 11 and the second centering plane 12 place.When this alignment device installed by workpiece 3, by tightening three holding screws 2 on body 1, the head of holding screw 2 is pushed against on the outer surface of workpiece 3, alignment device is fixed on workpiece 3.
Adopt the alignment device of said structure to carry out centering man-hour to workpiece 3 as shown in Figure 1 adding, for the workpiece 3 of this structure, lathe adds man-hour, with the V-block positioning and clamping workpiece 3 being applicable to height, first mill out the first keyway 31.Carry out in accordance with the following steps during centering:
After workpiece 3 processes the first keyway 31, the body 1 of alignment device is enclosed within the end of workpiece 3, then rotating body 1 is until make the first centering plane 11 on body 1 parallel with platen, the holding screw 2 tightened on body 1 makes body 1 be fixed on workpiece 3, and the first centering plane 11 now on body 1 is corresponding with the first keyway 31 position; Workpiece 3 on lathe is rotated 120 degree, and makes the second centering plane 12 on body 1 parallel with platen, on workpiece 3, the Working position of the second keyway 32 is determined.After the Working position of the second keyway 32 is determined, the workpiece 3 on fixing lathe, workpiece 3 processes the second keyway 32, and the second keyway 32 processed is corresponding with the position of the second centering plane 12, as shown in Figure 4.
In above-mentioned steps, by using the first centering plane 11 on dial gauge centering body 1 parallel with platen, by using the second centering plane 12 on dial gauge centering body 1 parallel with platen.
Below by reference to the accompanying drawings the utility model is exemplarily described.Obviously, the utility model specific implementation is not subject to the restrictions described above.As long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out; Or without improvement, above-mentioned design of the present utility model and technical scheme directly applied to other occasion, all within protection domain of the present utility model.
