Detailed Description
In order to make the objects, contents and advantages of the present invention clearer, the following detailed description of the embodiments of the present invention will be made in conjunction with the accompanying drawings and examples.
The embodiment provides a tool for unifying turning and milling machining benchmarks, which mainly comprises a positioning flange 1 and a fixed base 4.
The structure of the positioning flange 1 is shown in fig. 1. The big end of the positioning flange 1 is provided with a conical groove which can be matched with a flange of a lathe spindle or a boss of the fixed base 4, the dimensional accuracy of the conical groove can be guaranteed to be matched with the high flange of the lathe spindle, and the conical surface of the groove of the positioning flange 1 is a common reference surface during turning and milling. The groove adopts a conical surface design, can be automatically guided and aligned, and has higher positioning precision.
The big end of the positioning flange 1 is connected with a lathe spindle flange or a fixed base 4 through six semicircular built-in bolts 2 with arc gaps, and a rotation stopping bolt 3 is arranged beside each built-in bolt 2. The rotation angle of a semicircular locking bolt 5 which is also provided with an arc-shaped notch and arranged in a flange of a lathe spindle or a fixed base 2 is adjusted, so that the locking bolt 5 and the built-in bolt 2 are meshed and locked at 90 degrees, and as shown in figure 2, the connection mode can realize quick replacement. The small end of the positioning flange 1 is matched with the middle hole of the workpiece 6 with high precision and is connected through a hexagon bolt 7, as shown in figure 3.
The fixed base 4 is installed on a milling machine workbench, as shown in fig. 3, the structure of the fixed base is the same as that of a flange of a main shaft of a lathe, a conical boss matched with a conical groove of the positioning flange 1 is arranged at the top of the fixed base, and a locking bolt 5 with an arc-shaped notch is also arranged inside the fixed base and used for being meshed and locked with a built-in bolt 2 of the positioning flange 1 at an angle of 90 degrees to lock the positioning flange 1.
When the tool is used for turning, the built-in bolt 2 is firstly installed in a threaded hole at the large end of the positioning flange 1, the rotation stopping bolt 3 is installed, then the positioning flange 1 is installed on a main shaft flange of a lathe, the locking bolt 5 in the lathe flange is rotated to be locked with the built-in bolt 2, then the workpiece 6 is installed at the small end of the positioning flange 1, and the outer circle and the inner hole of the workpiece are finely turned.
After turning is finished, the positioning flange 1 and the workpiece 6 are detached from the lathe together, the next fine boring process is carried out, and the positioning flange 1 and the workpiece 6 are not detached in the circulation process. During fine boring, the fixed base 4 is installed on a milling machine workbench, a cutter is used for aligning and positioning the conical boss of the fixed base 4, then the positioning flange 1 and the workpiece 6 are installed above the fixed base 4 together, the locking bolt 5 in the fixed base 4 is rotated to be locked with the built-in bolt 2 of the positioning flange 1, and milling is started.
By the method, the lathe machining reference and the milling machine machining reference can be kept consistent, and the problem that the form and position errors are increased due to the fact that the reference is changed is solved. The tool can effectively unify the whole vehicle and mill the machining reference, guarantee the shape and position precision of the workpiece and improve the machining efficiency. The fixed base 4 is used as a zero point positioning system of the milling machine, when a hole is finely bored, a cutter only needs to align the boss of the fixed base 4 once, a workpiece does not need to be aligned again, and when the cutter is processed in batches, the processing efficiency can be greatly improved, and the cutter setting time is saved. By utilizing 90-degree cross locking of the two semicircular studs, quick disassembly and assembly can be realized, and the clamping time is shortened.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
