Description
Technical field
The utility model relates to a kind of concentricity detection tool.
Background technology
This kind of apparatus for rotating be made up of rotor and stator such as Multi-stage centrifugal fan, centrifugal pump, assembles concentricity preferably for equipment before assembly, all can do concentricity to the stator of locating shaft and detect; Conventional detection method is positioning datum point, be that workpiece rotates, measured point measured by dial gauge, and this method can along with the increase of parts, weightening finish and make testing tool load-bearing become large, thus rotating accuracy is become manufacture and measure a difficult problem, manufacture and maintenance cost also can increase at double; And the detection method of extraordinary concentricity detection tool is testing tool rotation, workpiece is static, and this detection method can not have impact on the manufacture of testing tool with measurement difficulty because the increase weightening finish of parts, and its manufacture and maintenance cost is also very low.
Utility model content
The utility model proposes a kind of concentricity detection tool, by rotation detection kit in the process detecting concentricity of workpiece, do not need to rotate workpiece for measurement, and not by the size of the swing diameter of work and the impact of weight, solve the problem that traditional concentricity detection tool makes cubing manufacture with the tactical diameter increase of measured workpiece and the increase of weight, maintenance cost is multiplied.
The utility model realizes particular by following technical scheme:
A kind of concentricity detection tool, comprise external conical sleeve, inner conical drogue, mandrel, bearing box, fulcrum bar component and dial gauge, the all tapered shape of inner and outer wall of described inner conical drogue and the tapered opening of the inwall of inner conical drogue are upward, the tapered opening of the outer wall of inner conical drogue down, the tapered shape of inwall of described external conical sleeve, the tapered shape of outer wall of mandrel, described mandrel is longitudinally placed in inner conical drogue, inner conical drogue is longitudinally placed in external conical sleeve, and external conical sleeve, inner conical drogue, mandrel three coincide, the top and bottom of described inner conical drogue are respectively equipped with upper locking nut and lower locking nut; The upper end of described mandrel is arranged in bearing box, and described bearing box top is provided with lock-screw, and described fulcrum bar component is fixed on bearing box by lock-screw, and described fulcrum bar component end fixes dial gauge.
Further, described fulcrum bar component end, by rotating shaft installing connecting rods, dial gauge is installed by described connecting rod.
The beneficial effect that the utility model produces is: the detection method of concentricity detection tool of the present utility model is that testing tool rotates, workpiece is static, this testing tool can not increase weightening finish to the impact of testing tool manufacture with the factor of measurement by parts, manufacture and maintenance cost is also very low, its structure is simple, and easy accessibility is easy to operate, carry and deposit conveniently, manufacture, maintenance cost is low.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of concentricity detection tool, comprise external conical sleeve 1, inner conical drogue 2, mandrel 3, bearing box 4, fulcrum bar component 6 and dial gauge 7, the all tapered shape of inner and outer wall of described inner conical drogue 2 and the tapered opening of the inwall of inner conical drogue are upward, the tapered opening of the outer wall of inner conical drogue 2 down, the tapered shape of inwall of described external conical sleeve 1, the tapered shape of outer wall of mandrel 3, described mandrel 3 is longitudinally placed in inner conical drogue 2, inner conical drogue 2 is longitudinally placed in external conical sleeve 1, and external conical sleeve 1, inner conical drogue 2, mandrel 3 three coincide, the top and bottom of described inner conical drogue 2 are respectively equipped with upper locking nut 8 and lower locking nut 9.During detection, inner conical drogue 2 and mandrel 3 is locked by lower locking nut 9, mandrel 3 is prevented to be subjected to displacement, upper locking nut 8 is fixed on workpiece for measurement 10 simultaneously, upper locking nut 8 is in inner conical drogue 2 outer wall side surrounding and also and between external conical sleeve 1 there is gap, be fixed among this gap by workpiece for measurement 10, workpiece is fixed by adjustment upper locking nut 8.Due to external conical sleeve 1(spring clamp hair style), the architectural feature of inner conical drogue 2, when the size generation subtle change of workpiece, can there is the displacement automatic tension of above-below direction to adapt to the size of workpiece in inner conical drogue 2.
In the present embodiment, the upper end of mandrel 3 is arranged in bearing box 4, and described bearing box 4 top is provided with lock-screw 5, and fulcrum bar component 6 is fixed on bearing box 4 by lock-screw 5, and fulcrum bar component end, by rotating shaft installing connecting rods, described connecting rod is installed dial gauge 7.When detecting, the automatic tension of external conical sleeve 1, inner conical drogue 2 after nut fixation workpiece, in diagram, the position that workpiece is fixed is reference point A, the measured point B in dial gauge 7 alignment pieces, and rotary supporting rod assembly 6 drives bearing box 4 to rotate, because the bearing of bearing box 4 inside connects, mandrel can not rotate.In the process that fulcrum bar component 6 rotates, dial gauge wheel measuring concentricity.Be in further fulcrum bar component 6 be provided with balancing weight 11 to prevent in rotary course because connecting rod the weight at the two ends of axis of fixing inconsistent and cause bearing clearance entirely monolateral, fulcrum bar component 6 is rotated not steady, and fulcrum bar component end is by rotating shaft installing connecting rods, described connecting rod is installed dial gauge 7, thus its life-span of the wobble effects avoiding dial gauge larger, according to the different tactical diameters of different workpieces, degree of tightness trip bolt 5, adjustment length of connecting rod, then be fixed, to coordinate the structure of workpiece to measure.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
