Background
The purpose is along with the development and application of super high speed electric main shaft technique, numerical control machine tool technique and advanced manufacturing techniques such as high-speed cutting, high-speed processing are developed at a rapid pace, the feeding drive of the numerical control machine tool is required to realize high-speed feeding and high-precision rapid positioning, and the ball screw pair is the optimal choice of the existing high-speed drive. Bearing steel GCr15 or GCr15SiM is generally adopted in domestic lead screw processing, the material is not suitable for manufacturing lead screws under a high-load working state due to good through hardening and high hardness, but has poor toughness and comprehensive mechanical properties, and is not suitable for manufacturing high-purity high-precision SAE4150 steel for ball screw countershafts in some international enterprises.
In the processes of heating, rolling, cooling, heat treatment and transportation of the bar, due to the influence of various factors, multi-directional bending defects often exist. To eliminate the bending and to obtain a straight finished product, the bar needs to be straightened on a straightening machine.
Because the straightening of the steel is a process of rotating while advancing, the steel is subjected to multi-pass bending deformation in a roll gap, if the roll shape is unreasonable in design, the maximum jumping values of different parts of the straightened steel can be changed according to a certain angle, namely snake-shaped bending occurs, namely the directions of the bending are inconsistent, and the bending with the property is difficult to straighten in the screw rod processing.
The conventional measuring method is finished by moving a dial indicator, namely moving the dial indicator along the central axis direction of the section steel rolled stock, and detecting the straightness and the curvature in the set length by displaying the radial deviation of a numerical detection position through the dial indicator.

Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 1 and 2, the utility model relates to a high-purity high accuracy steel crookedness measuring device for ball screw axle, including placing frame 1 subaerial be provided with measuring platform 2 in frame 1, measuring platform 2 has higher levelness even interval is provided with five groups of supporting rolls 3 on measuring platform 2's both ends and the platform, and the gyro wheel on every group supporting roll 3 is arranged in pairs, is convenient for place steel 4, can make things convenient for steel 4 radial rotation (rotation) on measuring platform in the measurement process simultaneously.
The measuring platform 2 is provided with a linear guide rail 5, the linear guide rail 5 is located on one side of the supporting rollers 3 and is parallel to the straight line where the five groups of supporting rollers 3 are located, the linear guide rail 5 is provided with a linear bearing 6 made of a metal material, the linear bearing 6 can do linear motion along the linear guide rail 5, the linear bearing 6 is provided with a dial indicator 8 through a magnetic indicator seat 7, and an ejector pin of the dial indicator 8 is in contact with the highest point of steel.
In actual production, in order to simplify quality control, bending run-out values of the same section of steel in two directions perpendicular to the X-Y direction are measured and recorded respectively, on one hand, the bending degree of the length direction of the steel is measured by the dial indicator 8 under the drive of a linear bearing, and on the other hand, the steel can be rotated at the same section position to detect the bending degree of the current section. Along with the change of the bending degree of the steel, the thimble can also move up and down, the pointer in the dial can change, and the change value is a bending bounce value. The heights of the 5 support wheels are adjusted to be the same level before measurement, the first point pointer in the X direction and the first point pointer in the Y direction are adjusted to be 0 during each measurement, then the distance between the two measurement points is not more than 200mm, the recorded X-Y direction measurement values of each cross section are made into continuous curves for comparison, the consistency of the two curves reflects the quality of the steel serpentine bending, the more consistent the curvature, the more ideal the curvature, see figure 2, and as can be seen from figure 2, the ideal level is achieved regardless of the curvature jumping value or the directionality.
In addition, the supporting rollers 3 at the two ends of the measuring platform 2 are connected with the air cylinder 9 installed on the rack 1, and the lifting and the lowering of the supporting rollers 3 at the two ends are realized through the lifting of the air cylinder 9, so that the bending degree of steel materials under the conditions of different supporting rollers can be detected.
In addition to the above embodiments, the present invention also includes other embodiments, and all technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
