Abstract

A follow -rest for processing slender axles, including the support body that has arc portion, be equipped with two locating support foots that are used for fixing a position the arc portion centre of a circle on the support body, the sufficient arc portion that follows of locating support radially extends, the sufficient zhi chengtou who takes the bearing surface that is equipped with of locating support, the bearing surface is the round ARC structure who matches with the slender axles work piece axle face of cylinder, its characterized in that: zhi chengtou is the cuboid structure, the bearing surface is the rectangle along the orthographic projection of zhi chengtou axis direction. The utility model discloses simple structure, the zhi chengtou of cuboid structure have replaced cylinder or cone structure's zhichengtou, and the area of its bearing surface can increase more than 20%, have effectively improved the power of clamping down on of auxiliary stay work piece, and its supporting effect has super strong stability.

Description

For the movable support of processing slim axle
Technical field
The utility model relates to a kind of machined into auxiliary tool head, the movable support of especially a kind of turning slender axles.
Background technology
The axial workpiece that Workpiece length and diameter ratio are greater than 25 is called slender axles by prior art usually, such as, feed rod on lathe, leading screw. Although slender axles profile is not complicated, but owing to himself rigidity is low, by the impact of the factors such as cutting force, gravity, heat in metal cutting during turning, easily produce vibration and flexural deformation, and produce the defects such as tapering, waist drum shape and ring shape, it is difficult to ensure working accuracy, makes cutting into as the bigger complete processing of difficulty of slender axles.
Existing working method is on the common lathe having movable support and steady rest, it may also be useful to supplemental support made by steady rest and movable support, increases the rigidity of workpiece, Reducing distortion. For the movable support of secondary process slender axles in prior art, its body is provided with two cast iron supporting foots, during turning workpiece, two cast iron supporting foots help piece surface, the supporting head of cast iron supporting foot is generally cylinder or conical structure, this kind of supporting head is provided with the circular arc supporting surface matched with excircle of workpiece, the area of its circular arc supporting surface is less, and power deficiency clamped down on by supplemental support workpiece, causes stability in the course of processing poor.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of movable support for processing slim axle, and its stability supporting workpiece is strong.
The utility model adopts following technical scheme: comprise the frame body with curved portions, described frame body is provided with two positioning support foots for locating the curved portions center of circle, positioning support foot is the extension of portion's radial direction arcuately, positioning support foot is provided with the supporting head of band supporting surface, described supporting surface is the round globoidal structure matched with slender axles workpiece spindle cylindrical surface, described supporting head is rectangular structure, and described supporting surface is rectangle along the orthographicprojection in supporting head axis direction. Its principle is: the supporting head of rectangular structure, compares with the supporting head of cylinder or conical structure, and the area of its supporting surface can increase more than 20%, and its supporting role has superpower stability.
The utility model structure is simple, and the supporting head of rectangular structure replaces the supporting head of cylinder or conical structure, and the area of its supporting surface can increase more than 20%, and what effectively improve supplemental support workpiece clamps down on power, and its supporting role has superpower stability.
Accompanying drawing explanation
Fig. 1 is the assembly structure schematic diagram of a kind of embodiment of the utility model.
Fig. 2 is supporting head perspective view of the present utility model.
Fig. 3 is the main TV structure schematic diagram of three kinds of supporting heads (a kind of embodiment of column structure, conical structure and the utility model).
Fig. 4 is the comparison schematic diagram of the supporting surface stretch-out view of three kinds of supporting heads (a kind of embodiment of column structure, conical structure and the utility model).
In figure: frame body 1, positioning support foot 2, supporting surface 3, supporting head 4, the supporting head 5 of conical structure, the supporting head 6 of column structure.
Embodiment
As shown in Figures 1 to 4, a kind of embodiment of the utility model comprises the frame body 1 with curved portions, described frame body 1 is provided with two positioning support foots 2 for locating the curved portions center of circle, positioning support foot 2 is the extension of portion's radial direction arcuately, positioning support foot 2 is provided with the supporting head 4 of band supporting surface 3, described supporting surface 3 is the round globoidal structure matched with slender axles workpiece spindle cylindrical surface, and described supporting head 4 is rectangular structure, and described supporting surface 3 is rectangle along the orthographicprojection in supporting head 4 axis direction. Its principle is: the supporting head 4 of rectangular structure, compares with the supporting head 6 of the supporting head 5 of conical structure or column structure, and the area of its supporting surface 3 can increase more than 20%, and its supporting role has superpower stability.
As shown in Figure 3,5 is the supporting head of column structure, and 6 is the supporting head of conical structure, and 4 is the supporting head of a kind of movable support embodiment (rectangular structure) of the present invention. As shown in Figure 4, a, b, c are respectively the stretch-out view of the supporting surface of three kinds of different movable support supporting heads. A is conical structure, and b is column structure, and c is the rectangular structure of the embodiment of the present invention. By figure contrast it will be seen that the area of the supporting surface of several supporting head has notable difference, more little support stability is more poor for the area of supporting surface, the movable support supporting head of the present invention, and the area of its supporting surface is maximum, therefore its supporting role has superpower stability.
The utility model is not limited to the concrete structure of above-described embodiment, and other all falls within protection domain of the present utility model with the equivalent transformation of class formation.
