Abstract
The invention belongs to moving guiding mechanisms and particularly relates to a V-shaped guide rail for a down-the-hole drill. The V-shaped guide rail comprises a strip-shaped V-shaped protrusion and a sliding block, wherein the strip-shaped V-shaped protrusion is arranged on a base plate, and the sliding block is provided with a V-shaped groove and matched with the protrusion. Two inclined planes of the V-shaped protrusion are provided with stainless steel layers, the stainless steel layers can have the effect of abrasion resistance and corrosion resistance, and nylon layers are arranged on groove walls of the V-shaped groove of the sliding block simultaneously or independently to reduce friction and abrasion. According to another technical scheme, the nylon layers adhere to the two groove walls of the V-shaped groove of the sliding block, the technical scheme can be implemented independently and can also be implemented simultaneously with another technical scheme, and the nylon layers can greatly reduce friction and abrasion.
Description
Technical field
The invention belongs to movement guide mechanism, be specifically related to a kind of V-type rail of down-the-hole drill.
Background technology
Guide rail is structure conventional in plant equipment, its function is that constrained motion unit moves on the path of appointment, prior art middle guide is varied, comprise rail plate, rolling guide etc., yet for rail plate, owing to being to be slidably matched between its guide rail and slide block, therefore between guide rail and slide block, inevitably can produce friction, even smear a large amount of lubricants on the mating surface of the two, but still can produce wearing and tearing through guide rail after sliding for a long time and slide block, especially relatively severe in operating mode or the comparatively violent occasion of mechanical oscillation, this wearing and tearing meeting is more serious, the fuselage guide rail of down-the-hole drill for example, when boring, fuselage can produce violent vibration, the sewage simultaneously overflowing in boring also can cause corrosion and then guide rail is got rusty guide rail.
Summary of the invention
The object of this invention is to provide a kind of stable, wear-resisting, corrosion resistant V-type rail.
For achieving the above object, the invention provides following technical scheme: a kind of V-type rail, comprise the strip V-arrangement projection and the slide block that is provided with V-shaped groove with matching that on substrate, arrange, two inclined-planes of described V-arrangement projection are provided with stainless steel layer.
The technique effect of such scheme is: on guide rail, coated stainless steel makes it more wear-resisting, corrosion-resistant.
Another technical scheme provided by the invention is: a kind of V-type rail, comprise the strip V-arrangement projection and the slide block that is provided with V-shaped groove with matching that on substrate, arrange, and on two cell walls of described V-shaped groove, be pasted with one deck nylon layer.
The technique effect of such scheme is: is set the service life that nylon layer reduces side friction between itself and guide rail and then greatly improved guide rail on slide block.
Accompanying drawing explanation
Fig. 1 is the cutaway view that the present invention is applied to the embodiment of down-the-hole drill;
Fig. 2 is the I partial enlarged view of Fig. 1;
Fig. 3 is the perspective view of V-arrangement projection in the present invention;
Fig. 4 is the perspective view of bar section of stainless steel in the present invention;
Fig. 5 is the II partial enlarged view of Fig. 4.
The specific embodiment
Fig. 1 is the embodiment that the present invention is applied to down-the-hole drill, figure mid frame 10 is arranged on base 60, slide block 20 is provided with fixed head 30, on fixed head 30, be provided with for driving the rotary motor 50 of drill bit, rotary motor 50 is connected with a hydraulic cylinder 40, hydraulic cylinder 40 can drive rotary motor 50 to slide along V-type rail, V-type rail comprises strip V-arrangement projection 11 and the slide block 20 that is provided with V-shaped groove with matching arranging on the plate body of pedestal 10, it is characterized in that: two inclined-planes of described V-arrangement projection 11 are provided with stainless steel layer.Because rig vibrations in work engineering are more violent, if adopt its wearing and tearing meeting of ordinary carbon steel guide rail very serious, and in boring, the sewage that overflows can cause corrosion to guide rail, has a strong impact on the guide rail life-span, the surface of V-way is arranged to one deck stainless steel layer and just can address the above problem.
Another technical scheme of the present invention is to attach one deck nylon layer on two cell walls of the V-shaped groove of slide block 20, and this technical scheme can be implemented separately also can implement with above-mentioned another technical scheme simultaneously.Nylon layer is set on slide block 20 can reduce friction, and has avoided the metal covering of guide rail and slide block 20 to rub simultaneously, has greatly alleviated the wearing and tearing that the two is caused.
As shown in Figure 2,4, stainless steel layer is strip V-arrangement bar section of stainless steel 12, and described bar section of stainless steel 12 is coated in V-arrangement projection 11, between described bar section of stainless steel 12 and the faying face of V-arrangement projection 11, is provided with fixed cell.Bar section of stainless steel 12 does not need, through approval PROCESS FOR TREATMENT, only need simply cut into the length adapting with V-arrangement projection 11 and just can be directly installed in V-arrangement projection 11, thus this V-way make simple, convenient.
As Fig. 2, 3, shown in 5, the top of V-arrangement projection 11 is provided with at least two through holes 111 that connect V-arrangement projection 11 and substrate 10 along crest line direction, the angular bisector conllinear of the drift angle of the axis of described through hole 111 and V-arrangement projection 11, the angle of described bar section of stainless steel 12 is provided with at least two fixed blocks 121 along the length direction of bar section of stainless steel 12, distance between adjacent two fixed blocks 121 equates with the distance between adjacent two through holes 111, described fixed block 121 is provided with screwed hole 122, the angular bisector conllinear of the angle of the axis of described screwed hole 122 and bar section of stainless steel 12, described each fixed block 121 is placed in respectively in each through hole 111, bolt 13 inserts in through hole 111 and with screwed hole 122 formations on fixed block 121 and is threaded from substrate 10 1 sides.Adopt said method just can very easily bar section of stainless steel 12 be arranged on to protruding 11 of V-type and go up, be also convenient to the dismounting of bar section of stainless steel 12 and replacing simultaneously.
As shown in Figure 2, two cell walls of V-shaped groove on be respectively provided with dovetail groove one, described dovetail groove is along the length direction setting of V-shaped groove, described nylon layer comprises two nylon blocks 21 that are separately positioned on two cell walls of V-shaped groove, described nylon block 21 is provided with card article with the one side of the cell wall laminating of V-shaped groove, the cross sectional shape of described card article is dovetail shaped and adapts with the cross sectional shape of dovetail groove, and described card article is connected in dovetail groove.The card article of nylon block 21 and dovetail groove are directly interference fit, can allow like this nylon block 21 tightly be attached on the V-shaped groove wall of slide block 20, have guaranteed nylon block 21 surfacings, smooth simultaneously.
