A kind of linear rolling guide synthesis precision detector
Technical field
The present invention relates to a kind of instrument for testing precision, particularly a kind of linear rolling guide synthesis precision detector.
Background technology
Linear rolling guide generally is made up of guide rail, slide block, reverser, rolling body and retainer, it is a kind of rolling bearing of the novel relative linear reciprocating motion of work, can roll with the steel ball between slide block and guide rail replaces direct sliding contact, and rolling body can be realized infinite loop by reverser in raceway and slide block.Linear rolling guide has that friction factor is little, running precision is high, do not have creep, wear-resistant, advantage such as rigidity is high, thermal deformation is little, be widely used as the guiding parts of high-precision numerical control machine and machining center.
Need to carry out the measurement of synthesis precision after the linear rolling guide assembling before the shipment, to guarantee that product meets acceptance criteria, the synthesis precision of linear rolling guide is measured and is mainly adopted meter that each reference field of guide rail is carried out manual measurement on measuring table at present, this measuring method is troublesome poeration not only, labour intensity is big, efficiency of measurement is low, and the accuracy of measuring is relevant with operating personnel's mode of operation, causes measuring accuracy to be difficult to guarantee.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of easy and simple to handle, accuracy of detection is high, the linear rolling guide automatic measuring instrument of good stability.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of linear rolling guide synthesis precision detector, it comprises frame, frame is provided with the platform that is used to clamp linear rolling guide, be slidingly fitted with portal frame on the described platform, be lifted with 5 contactless gauge heads on the described portal frame, gauge head is slide block side, the position, left, center, right of slide block upper surface and the upper surface of platform of corresponding linear rolling guide respectively, be set with on the described portal frame can with the backstay of the guide rail contacts side surfaces of linear rolling guide;
As improvement of the technical scheme, the and arranged on left and right sides of described platform is provided with rail plate, and described portal frame is slidingly mounted on the rail plate;
As further improvement in the technical proposal, described portal frame top is provided with slide rail, be slidingly fitted with left and right longitudinal rod on the slide rail, clamping has gauge head moving up and down in the described left longitudinal rod, described right longitudinal rod can move up and down along slide rail, and be installed with cross bar bottom it, be movably installed with 4 gauge heads on the cross bar successively;
Further, described detector carries out the computer system that the linear rolling guide synthesis precision calculates after being provided with the data of collecting contactless gauge head;
Further, be slidingly fitted with portal frame more than three on the described platform; Described platform is two, is respectively arranged with the left and right sides of frame.
The invention has the beneficial effects as follows: this product can be used to measure the guideway width difference, the depth of parallelism of the relative guide rail of slide block upper surface bottom surface and the distortion of guide rail on length range, the height tolerance of guideway, contour, the short transverse depth of parallelism etc., simultaneously, by calculating the dynamic system error to eliminate when highly measuring, reach high-precision measurement, this measuring instrument adopts non-contact measurement, the accuracy of detection high stability is good, and the linear rolling guide that goes for different size detects, the detection efficiency height, easy and simple to handle, detect the The data data base administration, the convenient use and data sharing.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a portal frame structural representation of the present invention.
Embodiment
With reference to Fig. 1, a kind of linear rolling guide synthesis precision detector, comprise frame 1, frame 1 is provided with the platform 2 that is used to clamp linear rolling guide, in order to adapt to the specification of different guideways, described platform 2 can be two, be respectively arranged with the left and right sides of frame 1, be slidingly fitted with portal frame 3 on the described platform 2, this form of being slidingly installed is that guide rail connects, it is the left side of described platform 2, right both sides are provided with rail plate 21,22, described portal frame 3 is slidingly mounted on rail plate 21, on 22, in order to detect the precision of different model specification guideway simultaneously, be slidingly fitted with the portal frame 3 more than three on the described platform 2, be lifted with 5 contactless gauge heads 4 on the described portal frame 3, gauge head 4 is slide block 91 sides of corresponding linear rolling guide respectively, the left side of slide block 91 upper surfaces, in, the upper surface of right position and platform 2, be set with on the described portal frame 3 can with the backstay 32 of guide rail 92 contacts side surfaces of linear rolling guide.
With reference to Fig. 2, described portal frame 3 tops are provided with slide rail 31, be slidingly fitted with left and right longitudinal rod 5,6 on the slide rail 31, clamping has gauge head 41 moving up and down in the described left longitudinal rod 5, described right longitudinal rod 6 can move up and down along slide rail 31, and be installed with cross bar 7 bottom it, be movably installed with 4 gauge heads 42,43,44,45 on the cross bar 7 successively.
This product is in order to converse the various data of linear rolling guide automatically, and described detector carries out the computer system 8 that the linear rolling guide synthesis precision calculates after being provided with the data of collecting contactless gauge head 4.
The principle of work of this product is: gauge head 41 is used to measure the guideway width difference with backstay 32; Gauge head 41,43 is used to measure the depth of parallelism and the distortion of guide rail on length range of the relative guide rail of slide block 91 upper surfaces 92 bottom surfaces; Gauge head 42,45 is used to measure the height tolerance of guideway, contour, the short transverse depth of parallelism etc., and simultaneously, the data of the detection by gauge head 42,45 can also reach high-precision measurement by calculating the dynamic system error of eliminating highly measure the time.Can gather the accuracy data of each position in each detection position of guideway by computer system 8 with hand propelled portal frame 3 during measurement, thereby realize the measurement of guideway synthesis precision.
This measuring instrument adopts non-contact measurement, and the accuracy of detection high stability is good, and goes for the linear rolling guide detection of different size, detection efficiency height, easy and simple to handle, detection The data data base administration, the convenient use and data sharing.
