Other features and advantages of the present invention are described in detail in detailed description of the invention part subsequently.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.Should be understood that, detailed description of the invention described herein, only for instruction and explanation of the present invention, is not limited to the present invention.
Fig. 1 is the structural representation of the Magnetic suction ground compasses according to the specific embodiment of the present invention, and Fig. 2 is the plan structure schematic diagram of the Magnetic suction ground compasses shown in Fig. 1.
As depicted in figs. 1 and 2, comprise cutting according to the Magnetic suction ground compasses of the specific embodiment of the present invention and chew cover 1, slide bar 2, base 3, tumbler 4, magnetic patch 5 and securing member 7, wherein, cut and chew one end that cover 1 is arranged on slide bar 2, slide bar 2 is provided with elongated hole 9, securing member 7 is connected with the top of base 3 through elongated hole 9, and tumbler 4 and magnetic patch 5 are arranged on the bottom of base 3, and base 3 can be rotated relative to magnetic patch 5 by tumbler 4.
This Magnetic suction ground compasses can stablize the centre point of advising easily skew with firmly fixing, and improves the precision of processing work, reduces operating personnel and improves working (machining) efficiency simultaneously, and this Magnetic suction ground compasses cutting processing can be in the workpiece of inclined-plane or facade.
The structure of the Magnetic suction ground compasses that the specific embodiment of the present invention provides is described in detail below in conjunction with Fig. 1 and 2.As shown in the figure, cut and chew cover 1 and can be fixedly installed any one end being such as welded on slide bar 2, cutting and chew cover 1 can be any structure, as long as the function of installing the cutting torch (not shown)s such as oxyacetylene torch cutter can be realized, such as cut chew cover 1 can for cylindrical structure, the cutting torch such as described oxyacetylene torch cutter can be placed in cut and chew in cover 1 and chew cover 1 rotate relative to cutting.
Slide bar 2 can be provided with elongated hole 9 along its length, securing member 7 is connected with the top of base 3 through elongated hole 9, thus base 3 can be moved, after moving to preposition relative to slide bar 2, tightening fastener parts 7 locks, thus makes base 3 can be relative fixing with slide bar 2.In addition, the connection of securing member 7 and base 3 can adopt existing common being threaded, and namely the top of base 3 can be formed with screwed hole, and securing member 7 is formed with screw thread.
Tumbler 4 and magnetic patch 5 can be arranged on the central area of the bottom of base 3, and base 3 can be rotated relative to magnetic patch 5 by tumbler 4.As mentioned above, because base 3 is relative with slide bar 2 fixing by securing member 7, therefore, slide bar 2 and base 3 can together with rotate relative to magnetic patch 5, thus realize the above-mentioned cutting processing to workpiece.
Tumbler 4 and magnetic patch 5 can be arranged on the central area of the bottom of base 3 by various ways.Below by the specific embodiment of the present invention, two kinds of set-up modes will be described.
The first set-up mode: the bottom centre region of base 3 can form the circular groove with certain depth, tumbler 4 can be arranged in described circular groove, the height of tumbler 4 can be consistent with the degree of depth of described circular groove, the height of magnetic patch 5 is greater than the height of tumbler 4, and magnetic patch 5 is arranged on the inside of tumbler 4 and outwardly.Like this, magnetic patch 5 can maintain static, and base 3 can be rotated relative to magnetic patch 5 by tumbler 4.
In addition, tumbler 4 can adopt the form of bearing, now, the inner ring of this bearing is fixed together with magnetic patch 5, outer ring and base 3 are fixed, in order to prevent the rotation of inner ring to base 3 from having an impact, an annular packing ring can be provided with between the cycle surface of bearing and the bottom surface being formed in the described circular groove bottom base 3, thus make to form interval between the bottom surface of the inner ring of bearing and described circular groove.
In addition; this Magnetic suction ground compasses can also comprise sleeve 6; this sleeve 6 can be arranged on the inside of tumbler 4; in the inner ring of i.e. bearing; simultaneously; magnetic patch 5 is arranged on the inside of sleeve 6 and outwardly, do not contact, thus this sleeve 6 can play the effect of protection magnetic patch 5 with the bottom surface of described circular groove simultaneously.In addition, this sleeve 6 when mounted, should and magnetic patch 5 form interval together and between the bottom surface of described circular groove.
The second set-up mode: in this kind of set-up mode, this Magnetic suction ground compasses preferably includes sleeve 6.The bottom of base 3 can be formed with a circular projection (not shown), and tumbler 4 is arranged on this circular projection, and the outside of tumbler 4 is provided with sleeve 6, and magnetic patch 5 is arranged on the inside of sleeve 6 and outwardly.Like this, magnetic patch 5 and sleeve 6 can maintain static, and base 3 can be rotated relative to magnetic patch 5 and sleeve 6 by tumbler 4.
Tumbler 4 can adopt the form of bearing, and now, inner ring and the described circular projection of bearing are fixed, and the outer ring of bearing and sleeve 6 are fixed, and magnetic patch 5 is arranged on the inside of sleeve 6 and outwardly, simultaneously this magnetic patch 5 not with the end contact of described circular projection.In addition, in order to prevent the rotation of outer ring to base 3 from having an impact, an annular packing ring can be provided with between the inner ring end face of bearing and base 3 end face, thus make to form interval between the end face of the outer ring of bearing and base 3.
In addition, in order to can cutting processing is predetermined accurately workpiece, preferably, the both side surface of slide bar 2 can be provided with scale, thus can the size of predetermined cuts workpiece.
Tumbler 4 is described above, can adopt existing bearing.
In addition, when tightening fastener parts 7, damaging to prevent the scale on securing member 7 pairs of slide bars 2 from producing, preferably, between securing member 7 and slide bar 2, pad 8 can be provided with, thus play the effect of protection slide bar 2 high scale.
As mentioned above, the top of base 3 can be formed with screwed hole, and securing member 7 is formed with spiral shell, and therefore, securing member 7 can be preferably fastening bolt.
In addition, in the cutting working environment of reality, in order to protect the end face of magnetic patch 5 from damage, preferably, the bottom of magnetic patch 5 can be provided with stainless sealing gasket.
Below the preferred embodiment of the present invention is described in detail by reference to the accompanying drawings; but; the present invention is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present invention; can carry out multiple simple variant to technical scheme of the present invention, these simple variant all belong to protection scope of the present invention.
In addition, also can be combined between various different embodiment of the present invention, as long as it is without prejudice to thought of the present invention, it should be considered as content disclosed in this invention equally.
