The bending angle position of the dust cap is provided with a Y-shaped sealing part elastically contacting the side face of the slide rail; both end parts of a circulating channel of the steel ball of the slide seat are provided with fish eye holes corresponding to the flanges of the guide rails of the circulating covers. The utility model has the advantages of simple and reasonable structure, low manufacture cost, convenient operation and low noise.

Description

Ball slide

The utility model relates to a kind of structure of Ball slide, refers to the dust cover of functions such as having the steel ball retainer and prevent dust especially, and provides circulation to cover the Ball slide of precision positioning.

General Ball slide as the precision optical machinery sliding linearly, for preventing the foreign matter of external environment, for example dust, water or metal powder etc. are invaded the steel ball race way of slide, usually the bottom end at slide is fixed with a flat rubber dust cap, as shown in Figure 7, an end of this dust cover contacts with the side elastic of slide rail.When slide takes off on slide rail carrying out maintenance procedure, fall for making the unlikely glue of circulation steel ball that is positioned between slide and slide rail, be provided with the steel ball retainer made from linear metallic material at the slide place, this retainer is the linear grooves position that is positioned at slide rail.Assemblies such as existing this dust cover of slide and retainer are the independent component made from different materials, and are therefore no matter higher in manufacture cost, and complicated on the assembling operation.Retainer is to use the metallic material manufacturing, so steel ball is when circulating rolling, and steel ball may contact with retainer and sharp-pointed noise takes place.Process linear grooves on slide rail, its processing technique and precision are very complicated.The two ends of slide are provided with the circulation lid of guiding steel ball circulating rolling, and this follows lid is to locate on slide with the screw locking.Because the steel ball track of circulation lid must the accurate circulation canal that aligns slide.Therefore the location of circulation lid often needs just can finish by the cooperation of other combination tool.

The purpose of this utility model provides a kind of Ball slide at the deficiencies in the prior art exactly, and it has the steel ball retainer and reaches functions such as dustproof, and realizes simply and easily circulating covering precision positioning.

The purpose of this utility model is achieved in that a kind of Ball slide, it includes Π shape slide, circulation lid, the linear slide rail at slide two ends and be configured in the dust cover of slide lower end, the section of its dust cover is a L type shape, its fixed end is fixed on the slide lower end, another free end then extends to slide rail recess place, and its end contacts with the circulation steel ball; There is the Y type sealed department that contacts with the slide rail side elastic corner of dust cover; The two end part of slide steel ball circulation canal are the corresponding fish eyelet of bead that builds guide rail with circulation.

Described dust cover is the rubber material material.

The free end shape of described dust cover is corresponding with the steel ball circular arc.

The free end of described dust cover and contacting of steel ball are centered close to the scope of the oblique miter angle of steel ball.

Include steel disc in the described dust cover.

The steel disc of described dust cover and circulation steel ball have a distance.

Described dust cover Y type sealed department is positioned at the outstanding position of slide rail recess bottom.

Described circulation lid is one-body molded for metallic material.

The steel ball circulation canal of described slide both sides is for setting independently circulation lid.

The utility model is simple and reasonable, and manufacture cost is lower, and is easy to use, and noise is less.

Below in conjunction with accompanying drawing and specific embodiments the utility model is described in further detail.

Fig. 1 is a schematic perspective view of the present utility model.

Fig. 2 is the front elevation of Fig. 1, the combination relation between its expression slide, slide rail and dust cover.

Fig. 3 is the front elevation of the utility model steel ball circulation lid.

Fig. 4 is the top view of Fig. 3.

Fig. 5 is the alternate embodiment of Fig. 4 dust cover.

Fig. 6 is the alternate embodiment of Fig. 5 dust cover.

Fig. 7 is the front elevation of existing Ball slide.

Referring to Fig. 1, Ball slide A of the present utility model includes circulation lid 2, the linear slide rail 3 at Π shape slide 1, slide 1 two ends and is configured in the dust cover 4 of slide 1 lower end.Slide rail 3 slides 1 sliding linearly on slide rail 3.

Be provided with circulation steel ball 5 between the inwall of slide rail 2 both sides and slide 1, the both sides of slide 1 are provided with provides steel ball 5 by circulation canal 11, and as shown in Figures 1 and 2, the two end part of circulation canal 11 are fish eyelet 111.

The two ends of slide 1 are fixed with the circulation lid 2 of steel ball 5 circulating rollings of leading the way, as shown in Figures 3 and 4, this circulation lid 2 is formed with bead 22 with fish eyelet 111 configurations with respect to slide circulation canal 11 places, and therefore circulation cover 2 during with slide 1 combination, covers 2 accurate localization but circulate.2 usefulness metallic material are covered in circulation, and to take off method with precision one-body molded, so its track 21 can be kept the precision of its expection.

The 2 steel ball circulation canals that comprise slide 1 both sides covers in circulation, and circulation cover 2 are metallic material manufacturings, therefore circulation is covered 2 and is had suitable weight, it does not make locating of its inconvenience when assembling, and wastes metallic material.Edge this, the steel ball circulation canal of slide 1 both sides is set independently circulation separately, and to cover 2 also be feasible mode.

The place, below that the side of slide rail 3 is equivalent to following circulation steel ball 5 is formed with the recess 31 that keeps suitable spacing with slide 1 inwall, as shown in Figure 2.

Dust cover 4 usefulness rubber or other elastic materials are made, and its section is L-shaped, and as Fig. 2 and shown in Figure 5, its fixed end 41 is the lower ends that are fixed in slide 1, and another free end 42 then extends to slide rail recess 31 places, and its end suitably contacts with circulation steel ball 5; Because dust cover 4 is with the rubber elastic material manufacturing, steel ball 5 contacts with dust cover free end 42 and does not produce noise.

The shape of the free end 42 corresponding steel ball circular arcs 5 of dust cover 4, and it approximately is positioned at the scope of steel ball 5 oblique miter angles with the center that contacts of steel ball 5, when therefore slide 1 took out from slide rail 3 places, the steel ball 5 that is positioned at 3 of slide 1 and slide rails can make free end 42 unlikely the coming off of supporting of dust cover 4.

The corner of dust cover 4 is formed with the Y type sealed department 43 with the suitable Elastic Contact in slide rail 3 sides, and sealed department 43 is positioned at the outstanding position of slide rail recess 31 bottoms; By the effect of Y shape sealed department 43, make dust cover 4 have dual dust reduction capability.

Because dust cover 4 rubber material manufacturing, and free end 42 extensions one segment length of dust cover 4 for avoiding its free section 42 because of length rigidity deficiency, causes supporting that the locating effect of steel ball 5 is bad to slide rail recess 31 places; Show a kind of dust cover 4 of additional steel disc 44 at Fig. 6, its steel disc 44 fits into one with the rubber precision in penetrating mould; Steel disc 44 extends to and the steel ball 5 that circulates keeps the distance of setting, because dust cover 4 is provided with steel disc 44, so the free end 42 of dust cover 4 has appropriate rigidity.
