Abstract
The invention discloses a method for detecting the concentricity of a screw rod. The method comprises the steps of: (1) inserting the head of a core rod into an inner hexagon hole in a shaft head of the screw rod for correct location; (2) mounting a bearing on a shaft shoulder of the screw rod, and locating the screw rod on a V-shaped block on a horizontal plate by the bearing; and (3) testing the jumping movement of the tail part of a cylindrical rod relative to the bearing by a dial indicator. In such way, the inner hexagon hole in the shaft head of the screw rod is transformed into the core rod and the cylindrical rod, and the concentricity of the inner hexagon hole relative to the shaft shoulder is determined by detection of the jumping movement of the cylindrical rod relative to the bearing. The method has the advantages of simple structure, convenience for operation, accurateness and reliability.
Description
This case is that application number is 201010168097.9, and name is called dividing an application of " a kind of screw concentricity detecting device and detection method ".
Technical field
The present invention relates to a kind of screw concentricity detecting device and detection method.
Background technology
Shown in Figure 4 and 5, some screw mandrel class workpiece shaft shoulder 32 to the inner hexagonal hole 310 of the spindle nose 31 of screw mandrel 3 and screw mandrel 3 in technical requirement guarantees certain concentricity, after particularly on the shaft shoulder 32 bearing being installed, the circle of the inner hexagonal hole 310 relative shaft shoulders 32 is beated and will be guaranteed within the technical requirement allowed band, because the center line of inner hexagonal hole 310 is difficult for determining, so the concentricity of the inner hexagonal hole 310 relative shaft shoulders 32 is difficult for measuring.
Summary of the invention
Problem to be solved by this invention just provides a kind of screw concentricity detecting device simple in structure and easy to operate method for detecting concentricity of screw rod, inner hexagonal hole in the spindle nose of screw mandrel is changed into axle, by detecting the concentricity of beating to determine inner hexagonal hole of axle, accurately reliable.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: a kind of screw concentricity detecting device, it is characterized in that: comprise the plug that the inner hexagonal hole in the spindle nose with screw mandrel cooperates and be plugged on cylindrical rod in the plug, described plug is concentric with cylindrical rod, the head of described plug inserts inner hexagonal hole, the opposite side distance of the xsect of described plug afterbody surpasses the opposite side distance of the xsect of inner hexagonal hole, and the plane at relative plug axis place, the side of plug has a tapering.
Further, described tapering is 5 °.
Further, the opposite side distance of the xsect of described plug afterbody is than the opposite side distance of the xsect of inner hexagonal hole large 0.1 millimeter.
Further, described plug and cylindrical rod interference fit.
The present invention also provides a kind of method for detecting concentricity of screw rod in addition, it is characterized in that: may further comprise the steps,
1) inner hexagonal hole that the head of plug is inserted in the spindle nose of screw mandrel is had good positioning;
2) at the shaft shoulder of screw mandrel bearing is installed, by bearing screw mandrel is positioned on the vee-block on the leveling board;
3) use beating of the dial gauge test relative bearing of cylindrical rod afterbody.
Further, described plug and inner hexagonal hole concentric fit.
After adopting technique scheme, the present invention has following advantage: the inner hexagonal hole in the spindle nose of screw mandrel is changed into plug and cylindrical rod, by detecting the concentricity of beating to determine the relative shaft shoulder of inner hexagonal hole of the relative bearing of cylindrical rod, simple in structure, easy to operate, accurately reliable.

The structural representation of an embodiment of the present invention as shown in Figures 1 to 3, a kind of screw concentricity detecting device, comprise the plug 1 that the inner hexagonal hole 310 in the spindle nose 31 with screw mandrel 3 cooperates and be plugged on cylindrical rod 2 in the plug 1, plug 1 and cylindrical rod 2 concentric and plugs 1 and cylindrical rod 2 interference fit, the head of plug 1 inserts inner hexagonal hole 310, the opposite side distance of the xsect of plug 1 afterbody surpasses the opposite side distance of the xsect of inner hexagonal hole 310, and the plane at relative plug 1 axis place, the side of plug 1 has a tapering, and preferred tapering is 5 °.
The present invention also provides a kind of method for detecting concentricity of screw rod in addition, may further comprise the steps,
1) inner hexagonal hole that the head of plug is inserted in the spindle nose of screw mandrel is had good positioning;
2) at the shaft shoulder of screw mandrel bearing is installed, by bearing screw mandrel is positioned on the vee-block on the leveling board;
3) use beating of the dial gauge test relative bearing of cylindrical rod afterbody.
By the relative bearing of centimeter check cylindrical rod afterbody beat determine whether the concentricity of the relative shaft shoulder of inner hexagonal hole satisfies technical requirement.
In above-described embodiment, large 0.1 millimeter than the opposite side distance of the xsect of inner hexagonal hole of the opposite side distance of the xsect of plug afterbody, the present invention changes into plug and cylindrical rod with the inner hexagonal hole in the spindle nose of screw mandrel, by detecting the concentricity of beating to determine the relative shaft shoulder of inner hexagonal hole of the relative bearing of cylindrical rod, simple in structure, easy to operate, accurately reliable.
Except above preferred embodiment, the present invention also has other embodiment, and those skilled in the art can make according to the present invention various changes and distortion, only otherwise break away from spirit of the present invention, all should belong to the defined scope of claims of the present invention.
