Description

Rail joint detection means

Technical field

The utility model discloses a kind of rail joint detection means, belong to precision optical machinery manufacturing technology field.

Background technology

Linear slide rail is important mechanical organ, is widely used such as precision optical machinery, Automation Industry, semiconductor The fields such as industry, Medical Devices, space flight space industry, the main function of linear slide rail is to apply ball or the rolling of roller Frictional resistance when reducing mechanism is mobile, makes mechanism more laborsaving when mobile, and energy saving, simultaneously because friction reduces, The abrasion of contact surface reduces so that there are larger lifting, and the translational speed limit of mechanism in the precision of mechanism and life-span Also significantly lifted forward a lot, therefore linear slide rail can deserve to be called highly important mechanical transmission component in recent years.

During actually used, the length of required track may be long, and when producing track, its length limited in The length of production line and can not possibly be very long, if desired for using very long track, need multistage track is stitched together, to increase The length of track, because track is very accurate mechanical organ in itself, may produce to the measure of precision of track in splicing Certain impact, if two track stitching portion process are bad, its impact is not only at rail joint, spliced whole rail The glacing flatness in road is also difficult to ensure that, therefore the detection to rail joint is extremely important in machinery manufacturing technology field, and existing Track splicing, substantially be difficult to detection splicing glacing flatness.

Content of the invention

The purpose of this utility model is to provide a kind of rail joint detection means, solves prior art middle orbit spliced It is difficult to the technological deficiency of fixation during glacing flatness detection.

For solving the above problems, the technical solution adopted in the utility model is：A kind of rail joint detection means, the bottom of including Seat, the both sides of described base upper end arrange the draw-in groove matching with track, and the two sides of base are respectively arranged with multiple use In the clamping device being fixed on track on base, on described draw-in groove along draw-in groove length direction have multiple for by track It is fixed on the first screwed hole on base.In the application, track is prevented in draw-in groove, the base in the application has first Screwed hole, with hexagon socket head cap screw and the cooperation of the first screwed hole, hexagon socket head cap screw is inserted into the countersunk head in the hole on track, and track is solid It is scheduled on base, with clamping device, track is fixed further simultaneously, prevent track from rotating in the detection, in the detection, The end of the two tracks track having spliced that connects is respectively bolted on base, and is fixed with clamping device respectively, Then detected to being spliced into dial gauge, observe the glacing flatness to determine track splicing for the white registration respectively, this practicality is new Type middle orbit one side surface is close to card groove sidewall, and draw-in groove itself also functions to certain position-limiting action to track.

As further improvement of the utility model, described clamping device is the metal being detachably arranged on base Block.The structure of metal derby is simple, easy to make, low cost, good economy performance.

As further improvement of the utility model, described metal derby is cuboid, square along its length on metal derby To having waist through hole, described base has the second screwed hole, described metal derby by through waist through hole and with The bolt of the second screwed hole screw thread cooperation is removably mounted on base.Waist through hole is opened on metal derby in the utility model, Metal derby is detachably arranged in the second screw thread in the hole on base by blending bolt, and waist through hole makes the metal derby can be along kidney-shaped The length direction motion in hole, when base is placed on the larger supporting surface of area, pulls up metal derby, makes the bottom of metal derby Portion is increased with supporting surface distance, is easy to rotate metal derby, conveniently clamps or unclamp track.

As further improvement of the utility model, described bolt is hexagon socket head cap screw.Fixed using hexagon socket head cap screw Metal derby, is easy to fasten, and dismounting, it is not easy to sliding angle, is easy to the fixation of track.

As further improvement of the utility model, the side that one end of described metal derby is parallel with bolt arranges rounding Angle.In the application, rounding is arranged on metal derby, reduce the volume of metal derby, be more beneficial for metal derby around for fixing gold The bolt belonging to block rotates.

In sum, the beneficial effects of the utility model are：Will by the first screwed hole on base and clamping device Two are stitched together into a long track and are fixed on base, then detect the glacing flatness of stitching portion, keep for use Splice track all meets flatness requirements.The utility model also has structure simply, easy to operate, the advantage of good economy performance.

Specific embodiment

Below in conjunction with the accompanying drawings specific embodiment of the present utility model is described further.

Rail joint detection means as shown in Figure 1 to Figure 3, including base 1, the both sides of described base 1 upper end are arranged The draw-in groove 2 matching with track, the two sides of base 1 are respectively arranged with multiple folders for being fixed on track on base 1 Tight device 4, on described draw-in groove 2, the length direction along draw-in groove 2 has multiple the first spiral shells for being fixed on track on base 1 Pit 3.In use, the base 1 in the application is placed on bracing frame（In figure is not shown）On.

In the application, preferred clamping device 4 is the metal derby being detachably arranged on base 1, and described metal derby is Cuboid, metal derby has waist through hole 5 along its length, and described base 1 has the second screwed hole 6, described Metal derby by through waist through hole 5 and with the second screwed hole 6 screw thread cooperation bolt 7 be removably mounted on base 1. In the application, preferred bolt 7 is hexagon socket head cap screw.

For ease of rotating the clamping device 4 in the application, the side setting that one end of described metal derby is parallel with bolt is fallen Fillet 8.

As shown in Figure 4 and Figure 5 be use state figure of the present utility model, be stitched together there being two track elements Track 9 prevents on draw-in groove 2, and the one side of track 9 props up the side wall of draw-in groove 2, track 9 has counter sink 10 in itself, this Shen Please in the first screwed hole 3 spacing setting the spacing with the counter sink 10 on track 9 equal, with hexagon socket head cap screw pass through track Track is tentatively fixed on the draw-in groove 2 of base 1 by the counter sink 10 on 9, hexagon socket head cap screw and the cooperation of the first screwed hole 3 screw thread, Rotating bolt 7, makes clamping device 4 loosen, and rotates clamping device 4 to vertical state, and makes waist through hole 5 edge of clamping device 4 Bolt 7 to move, and turn bolt 7, compress clamping device 4, clamping device 4 further compresses track 9, realizes track 9 Fixing.After track 9 is fixing, use dial gauge（In figure is not shown）Side head along track 9 apparent motion, should during keep hundred Divide table to move along a straight line along this direction parallel with the length direction of track 9, observe the change of pointer on dial gauge round dial, such as Pointer is substantially unchanged or change is less, then preferably, such as on dial gauge round dial, the swing of pointer is relatively for the glacing flatness of track 9 Greatly, then the glacing flatness of track 9 is poor.

In the application, the both sides of base 1 are provided with draw-in groove 2, and the size of two draw-in grooves 2 can be according to the type of track to be detected Number determine, the size of two draw-in grooves 2 can communicate, also can be different, with specific reference to being actually needed determination.

Be not specifically noted in all the utility model specifications is prior art or can by existing technology Realize it should be appreciated that for those of ordinary skills, being improved according to the above description or converting, and All these modifications and variations all should belong to the protection domain of the utility model claims.
