Abstract
The utility model relates to a detection device, especially to a detection rod used for the alignment of ball screw installation. The detection rod is characterized in that a shaft shoulder is arranged in the middle of the detection rod, and two ends of the detection rod are symmetrical relative to the shaft shoulder. By employing a two-end symmetrical form, the detection rod effectively extends detection scope, and the gravity center of the detection rod is positioned at the symmetrical center of the detection rod, thus the overhanging end of the detection rod is prevented form going down caused by unbalance forces, so that detection precision is liable to be improved, the detection rod has the characteristics of simple operation, reasonable structure, and the like, and the detection rod is especially suitable for the detection of the positioning precision of the ball screw in precision devices such as a high-speed machining center, and the like.
Description
Technical field
The utility model relates to pick-up unit, particularly a kind of test bar that is used for ball-screw installation centering.
Background technology
Because ball-screw has kinematic accuracy, sport efficiency and characteristics such as rigidity height, no sideshake, it is widely used in high-speed machine tool at present, particularly precision equipment such as high-speed machining center.
Because machine belongs to the precise motion parts at ball-screw, needs to carry out centering and adjustment to the right alignment between the mounting hole in ball-screw two positioning seats with the depth of parallelism of line rail before installation.Present employed test bar is the pole of an end shaft shoulder, the mounting hole that during detection the shaft shoulder is inserted in the ball-screw positioning seat detects, though the mounting hole in the shaft shoulder on the test bar and the ball-screw positioning seat is that precision matches, but owing to be that cantilever is installed, gravitate also can occur certain sagging, and the length that detects is shorter, thereby has influence on the precision of detection.
Summary of the invention
The purpose of this utility model is the defective that overcomes prior art, when a kind of detection is provided point of fixity in the centre, and two ends be symmetrically distributed be used for the test bar that ball-screw is installed centering.
The utility model is realized by following skill scheme: a kind of test bar that is used for ball-screw installation centering, it is characterized in that there is the shaft shoulder centre of test bar, and the test bar two ends are with shaft shoulder symmetry.
The utility model is owing to adopted the two ends symmetric form, can effectively prolong sensing range, the center of gravity of test bar is positioned at its symcenter, therefore, the projecting end of test bar can not sink because of force unbalance, help improving accuracy of detection, have characteristics such as simple to operate, rational in infrastructure, be particularly suitable for the detection of the ball-screw bearing accuracy in the precision equipments such as high-speed machining center.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Synoptic diagram is installed, detected to accompanying drawing 2 for utility model.
Embodiment
As shown in Figure 1, there is the shaft shoulder 8 centre of test bar 7, and the test bar two ends that is to say the test bar at shaft shoulder two ends with shaft shoulder symmetry, and diameter, length are all consistent.During use the shaft shoulder on the test bar is inserted on the ball-screw holder 6 in the pilot hole, pilot hole matches on the shaft shoulder on the test bar and the ball-screw holder 6, and this cooperation can be adopted transition fit.This moment, ball-screw holder 6 was all stretched out at the two ends of test bar.Behind lathe line rail 1 centering, place slide block 2 on the online rail, on slide block, place and detect with platform gauge stand 3, magnetic force gauge stand 4 and clock gauge 5, clock gauge is contacted with the test bar cylindrical, promote slide block rail direction along the line and move around, can effectively measure the ball-screw pilot hole in the ball-screw holder and the depth of parallelism of line rail.Test bar is installed on the two ball-screw holders 6 respectively and measures in the pilot hole, just can calculate the right alignment of pilot hole on the two ball-screw holders 6.Owing to can detect shaft shoulder two ends test bar when detecting, improved detection length effectively, thereby accuracy of detection is improved.
Claims (1)
1. one kind is used for the test bar that ball-screw is installed centering, it is characterized in that there is the shaft shoulder (8) centre of test bar (7), and the test bar two ends are with shaft shoulder symmetry.
