Introduction
This specification is mainly based on the standard GB/T 17587.1-1998eqvISO 3408-3.1992 "Ball
Deputy Part 1. Terminology and Symbols ", GB/T 17587.3-1998eqvISO 3408-3.1992" Ball
Vice - Part 3. Acceptance conditions and acceptance tests. "
The specification for the revision, instead of JJG671-1990 "screw dynamic measuring instrument." Dynamic measuring instrument from the screw stroke
The principle and function of departure, redefined the metrological characteristics of the portfolio, including.
--- Probe frame motion instead of straightness in horizontal and vertical straightness when the movable table;
--- Probe head frame motion frame/tailstock parallel connection of the head frame/flat tailstock connection with the primary rail
Tailstock and a line of direction of movement of the direction of movement of the probe frame of two parallel composition metrological characteristics, instead of the head frame spindle taper
Axis of the hole and tailstock sleeve taper from the center line of the table moving rail difference value, the centerline of the headstock spindle taper
Parallelism with the table moving direction, tailstock sleeve taper parallel to the center line of the moving direction of the table and so on;
--- Stroke indication error instead of the x-axis is moved around the table, swing y-axis and z-axis;
Integrated measurement reproducibility --- instead of a multiple installation measurement repeatability and reproducibility of measurements multiple installations.
Standards and calibration methods have also been adjusted accordingly.
JJG671-1990 for the first release.

3 Terms
Terms and definitions GB/T 17587.1-1998 defined apply to this specification.
3.1 target stroke ls specifiedtravel [GB/T 17587.1-19983.2.4.5}
Goal lead with the rotation number of turns of the product.
Note. Sometimes the nominal target stroke by stroke and stroke compensation values.
3.2 The actual average travel lm actualmeantravel [GB/T 17587.1-19983.2.4.7}
Having a minimum of actual travel straightness deviation line.
3.3 effective stroke lu usefultravel [GB/T 17587.1-19983.2.4.8}
Has designated precision stroke portion (ie, travel plus the length of the ball nut body).
3.4 The actual mean travel deviation e0a or esa actualmeantraveldeviatione0aoresa {GB/T 17587.1-
19983.2.5.3]
In the effective stroke, the actual average travel itinerary lm nominal difference of l0 or actual average travel lm target
Ls the difference between the stroke.
3.5 V travelvariation stroke volume variation [GB/T 17587.1-19983.2.6}
Parallel to the actual mean travel lm and the actual value of the bandwidth inclusive trip curve.
Note. The amount of change in itinerary has been provided. 2π radian stroke and corresponding bandwidth value V2π; 300mm travel with relative bandwidth V300
Correspondence; effective stroke bandwidth values Vu, respectively.
Note. The above bandwidth allowed bandwidth (symbol is "p") and the actual bandwidth (symbol "a") of the difference.
For example. within 300mm stroke length allows bandwidth V300p; actual bandwidth efficient travel within the Vua.
4 Overview
Screw Dynamic Travel meter (hereinafter referred to as the screw measuring instrument) is a measure of the quality of the screw stroke equipment, measuring wire
