Description
Technical Field
The utility model belongs to the technical field of machining, and particularly relates to a tool for turning sector ring parts.
Background
The clamping tool of the lathe is mainly a three-jaw or four-jaw chuck, the chuck can only directly clamp a round shaft, a round ring or a square with symmetrical four sides, a part in a fan-ring shape (the intersection of a fan shape and the round ring) cannot be directly clamped on the lathe, and if the part is machined in other modes, the efficiency is low and the size roughness is difficult to guarantee.
SUMMERY OF THE UTILITY MODEL
The utility model provides a tool for turning an annular part, aiming at the problem that the existing clamping tool of a lathe cannot clamp the annular part. A tool similar to a mandrel is fixed on a lathe chuck, and then a part is placed between the tool and the chuck to be clamped, so that the sector-shaped part is clamped. The processing method has the characteristics of quick centering, simple operation and stable clamping.
The utility model adopts the following technical scheme:
the utility model provides a frock for turning fan ring class part, is the circular shape frock body including the cross-section, the frock body includes the disc, one side of disc is equipped with disc I that is the ladder, the opposite side is equipped with disc II and disc III that are the ladder, the external diameter of disc III and the internal diameter clearance fit of the hollow chuck of lathe, the external diameter of disc II is greater than the internal diameter of chuck, the thickness of disc II is greater than the jack catch of lathe to the difference in height of chuck, the thickness of disc I is less than the thickness of fan ring class part, the external diameter of disc is the same with the internal diameter of fan ring class part, disc I is hugged closely with the terminal surface of fan ring class part.
Furthermore, the clearance between the outer diameter of the disc III and the inner diameter of the hollow chuck of the lathe is 0.15-0.2 mm.
Further, the outer diameter of the disc II is 30mm larger than the inner diameter of the chuck.
Further, the thickness of the disc II is 2-3mm larger than the height difference from the clamping jaws of the lathe to the clamping chuck.
Further, the thickness of the disc I is smaller than that of the fan ring type part by 15 mm.
The utility model has the following beneficial effects:
1. the utility model can realize the clamping of the fan-shaped annular part by the common four-jaw hollow chuck.
2. The utility model is easy to manufacture, self-centering, does not need to align the center of a part, and is convenient to use.
3. The utility model can realize that the turning processing of the end face and the chamfer can be completed only by once clamping.

Detailed Description
The utility model is further explained with reference to the accompanying drawings.
The utility model provides a frock for turning fan ring class part, is circular shape frock body 8 including the cross-section, frock body 8 includes disc 2, and one side of disc 2 is equipped with disc I3 that is the ladder, and the opposite side is equipped with disc II 4 and disc III 5 that are the ladder, the external diameter of disc III 5 and the internal diameter clearance fit of lathe hollow chuck 6, and the external diameter of disc II 4 is greater than the internal diameter of chuck 6, and the thickness of disc II 4 is greater than the jack catch 7 of lathe to the difference in height of chuck 8, and the thickness of disc I3 is less than the thickness of fan ring class part 1, and the external diameter of disc 2 is the same with the internal diameter of fan ring class part 1, and the terminal surface laminating of disc I3 and fan ring class part 1.
As shown in figure 3, the size B of the tool is matched according to the size of the inner hole of the chuck, the gap is 0.15-0.2mm, the size C is used as a spigot and is larger than the inner hole by 30mm, the size E needs to be larger than the height difference from the clamping jaw to the chuck by 2-3mm, and the tool and the chuck are prevented from interfering during clamping. The G size is smaller than the thickness of the part by 15mm under the condition of ensuring enough clamping firmness. The rest sizes are determined according to the sizes of the parts.
The manufacturing method of the utility model is as follows:
manufacturing a stepped shaft type disc tool, matching a first section of step of the tool with an inner hole of a hollow chuck of a lathe, wherein a second section of step is a spigot of the tool and the chuck, a third section of step and a fourth section of step are used for clamping workpieces, and the outer diameter of the fourth section of step is the inner diameter of a sector ring part. The end face of the fan ring part is tightly attached to the third section of step, the inner diameter of the fan ring part is attached to the outer diameter of the fourth section of step, and the chuck is tightened and directly pressed on the outer diameter of the fan ring part, so that clamping can be completed.
The present tool is not intended to be limited to the particular embodiments shown, which are exemplary rather than limiting, and those of ordinary skill in the art, in light of the present teachings, may be adapted to make various modifications without departing from the spirit of the present invention and the scope of the appended claims.
