Abstract
The utility model relates to a milling tool, in particular to a milling tool used for milling a circumferential key groove in an output shaft. The milling tool is used for solving the problems that when a circumferential key groove is milled in an existing output shaft, the rejection rate is high, and therefore not only is the economic loss caused, but also the whole term of product delivery is seriously affected. The milling tool comprises a positioning shaft (1) and a connecting cap (2), wherein the positioning shaft (1) is a stepped shaft, and the connecting cap (2) is provided with an inner hole (3) and detachably arranged on the upper portion of the positioning shaft (1). The milling tool is used for accurately positioning a workpiece, and alignment of the angular position for the workpiece each time is not needed, so that labor intensity of workers is relieved, the machining efficiency is improved by 20-23%, the economic loss is reduced, and the term of product delivery is effectively ensured. The milling tool is used for milling the circumferential key groove in the output shaft.
Description
Technical field
The utility model relates to a kind of milling tool, is specifically related to a kind of milling tool for output shaft milling circular keyway.
Background technology
Output shaft is the vital part of a lot of equipment, and this output shaft has high-precision keyway and need to process on circumference.Circumference keyway on detail drawing, groove width dimensional tolerance and Geometrical Tolerance Principle are tighter.Technique is to adopt four axis processing center milling circumference keyway, but part global shape is smaller, and clamping is unreliable, and workpiece needs to carry out centering after each clamping.In actual processing, groove width dimensional tolerance and form and position tolerance are unstable, and percent defective is high, and the economic loss not only causing is very large, and serious have had influence on the whole product term of delivery.
Utility model content
The purpose of this utility model is when solving existing output shaft milling circular keyway, and percent defective is high, not only causes economic loss, and serious has had influence on the whole product term of delivery.And then provide a kind of milling tool for output shaft milling circular keyway.
The technical solution of the utility model is: a kind of milling tool for output shaft milling circular keyway comprises locating shaft and attachment cap, and described locating shaft is multidiameter, and attachment cap is provided with endoporus, and attachment cap is detachably arranged on the top of locating shaft.
The upper end of described locating shaft is provided with positioning boss, and the intersection of positioning boss and locating shaft is provided with pit.
The utility model compared with prior art has following effect:
1. positioning boss of the present utility model can be located accurately to workpiece, by attachment cap by clamping workpiece on locating shaft, convenient mounting and clamping, reliable clamping
2. of the present utility model due to workpiece is accurately located, workpiece is without each centering angular position, thereby reduced labourer's labour intensity, and working (machining) efficiency has improved 20-23%, reduces economic loss, has also effectively guaranteed the product term of delivery simultaneously.
3. the utility model is applied to output shaft milling circular keyway on five shaft five linkage machining center and adds man-hour, take full advantage of the machining accuracy of lathe and the axial line function of Automatic-searching benchmark circular shaft, Dimension Measurement tolerance and form and position tolerance precision have better been guaranteed, the symmetry qualification rate of groove brings up to 95% by original 53%, the size qualification rate of groove width has brought up to 93% by 72%, thereby has improved the delivery-check qualified rate of part.
4. the utility model is simple in structure, is convenient to manufacture easy operating.
