Abstract
The utility model discloses a straightness detection device for a circular tube or rod. The straightness detection device comprises a detection platform inclining against a horizontal plane. A rigid cross beam is fixed on the detection platform via fixing brackets at two ends. A micrometer is fixedly connected onto each bracket via bolts and a pressing block. A gap of equal altitude is formed between the cross beam and the surface of a measuring platform. Strip holes are disposed in the fixed brackets. Screw holes are disposed in the cross beam. The cross beam is fixed onto the brackets via hand screw bolts penetrating into the strip holes in the fixed brackets. Through the hand screw bolts in the strip holes of the fixed brackets, the cross beam is fixed on the fixed brackets, and the stability of the gap size in the detection process is ensured. Through the micrometers, continuous variation of the gap size between the cross beam and the detection platform can be achieved, parts are not required to be removed or replaced when the detection size is changed, and the usage is easy. The micrometers can ensure the accuracy of the gap size.
Description
Technical field
The utility model relates to the linearity testing apparatus of a kind of pipe or pole, belongs to non-ferrous metals processing detection field.
Background technology
Current linearity testing apparatus forms by the contour derby of each pad of two ends between crossbeam and detection platform the contour gap of detecting use, detects the linearity of tube with various outer diameter and need to change contour derby.
Its major defect has: 1. the height of contour derby is fixed, if realize the detection of multiple different linearity requirements, need to be equipped with the contour derby of multiple differing heights, easily loses, obscures, and changes trouble, is not easy to management; 2. the machining precision of contour derby is limited, and along with the wearing and tearing of use procedure, its size accuracy can further reduce, and causes erroneous judgement while detection.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of applicability stronger, tubing, bar linearity testing apparatus that accuracy is higher.
The technical solution of the utility model is:
The linearity testing apparatus of a kind of pipe or pole, comprise and become skewed detection platform with surface level, in detection platform, be fixed with a rigid beam by the fixed support at two ends, be fixed on support and be fixedly connected with milscale by briquetting and bolt, between crossbeam and the surface of measuring table, form a contour gap.
On fixed support, have bar hole, have screw on crossbeam, crossbeam is bolted on support by the hand-screw in the bar hole through on fixed support.
Beneficial effect:
The utility model has been cancelled the design of contour derby, substitutes the effect of contour derby with measuring Metallic rod on milscale, realizes the adjusting to gap between crossbeam and detection platform.Realize crossbeam position fixing on fixed support by the hand-screw bolt in fixed support bar hole, ensure the stability of testing process intermediate gap size.Can realize the continuous transformation of gap size between crossbeam and detection platform by milscale, change while detecting size and do not need to change part, easy to use; Milscale can ensure the accuracy of gap size, and owing to being to use difference to calculate size, can not affect size accuracy because of the wearing and tearing in using.
Brief description of the drawings
Fig. 1 is one-piece construction schematic diagram of the present utility model;
Fig. 2 is fixed support partial structurtes schematic diagram.
In figure: 1-rigid beam, 2-detection platform, 3-fixed support, 4-milscale, 5-hand-screw bolt, 6-briquetting, 7-bolt, 8-pipe to be measured or pole.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
The linearity testing apparatus of a kind of pipe or pole, comprise the detection platform 2 that becomes skewed with surface level, in detection platform 2, be fixed with a rigid beam 1 by the fixed support 3 at two ends, be fixed on support 3 and be fixedly connected with milscale 4 by briquetting 6 and bolt 7, between crossbeam 1 and the surface of measuring table 2, form a contour gap.
On fixed support 3, have bar hole, on crossbeam 1, have screw, crossbeam 1 is fixed on support 3 by the hand-screw bolt 5 in the bar hole through on fixed support 3.
While regulating gap size, require to determine the size in 1 time gap of crossbeam according to the linearity of pipe to be measured or pole 8.The reading of both sides milscale 4 when first recording crossbeam 1 and being close to detection platform 2, then rotate milscale 4, rises to the height of crossbeam 1 identical with required gap length, finally by hand-screw bolt 5 fixed cross beam 1 positions.
When detection, pipe to be measured or pole 8 are freely rolled down from detection platform 2 upper end levels, being judged to of passing through from gap is qualified, otherwise defective, can be used for batch detection linearity.
Claims (2)
1. the linearity testing apparatus of a pipe or pole, comprise the detection platform (2) that becomes skewed with surface level, it is characterized in that: described detection platform (2) is upper is fixed with a rigid beam (1) by the fixed support (3) at two ends, be fixed on support (3) and be above fixedly connected with milscale (4) by briquetting (6) and bolt (7), between crossbeam (1) and the surface of measuring table (2), form a contour gap.
2. the linearity testing apparatus of pipe according to claim 1 or pole, it is characterized in that: described fixed support has bar hole on (3), crossbeam has screw on (1), and crossbeam (1) is fixed on support (3) by the hand-screw bolt (5) in the bar hole through on fixed support (3).
