Embodiment
By reference to the accompanying drawings; the utility model is elaborated; but protection domain of the present utility model is not limited to following embodiment, the simple equivalence of in every case being done with the utility model claim and description changes and modifies, within all still belonging to the utility model patent covering scope.
As shown in Figure 1, 2, 3, a kind of hand-rail type concentricity testing device, comprises worktable 1 and is located at clock gauge and the detector main component on this worktable.
Worktable 1 comprises marmorean platform 11 and is supported in the platform support 12 of this marmorean platform below.
Clock gauge comprises submeter base 21, dial holder 22 and clock gauge head 23, and clock gauge base 21 is fixed on the platform 11 that backing plate 20 is removably fixed in worktable by clock gauge, the convenient position of clock gauge at worktable of adjusting.
Detector main component comprises main body bearing 3, for placing first and second roller 41,42 and upper pressure handle 5, upper pressure handle fixture 6, upper pressure seat Bearing 7, handwheel 81 and the handle 82 of product to be detected, main body bearing 3 is fixed on web joint 31, this web joint 31 is fixed on pedestal bottom plate 32, and pedestal bottom plate 32 is fixed on again on the platform 11 of worktable.One end of first and second roller 41,42 respectively parallel interval is placed through on main body bearing 3, and this first and second roller can distinguish relative to main body bearing and rotate around himself axis, and this rotational structure can be selected bearing.One end of handle 82 is fixed on handwheel 81 lateral surfaces, on the medial surface of this handwheel 81, is fixed with rotating shaft, and this rotating shaft can be rotated to be fixed on main body bearing and (can be adopted bearing arrangement).Outside the rotating shaft of the first transmission gear 91 fixing sheathed handwheels, the second transmission gear 92 fixed covers are located at outside an end of the first roller, the 3rd transmission gear 93 fixed covers are located at outside an end of the second roller, the first driving cog 91 take turns between the second transmission gear 92 and this first transmission gear 91 and the 3rd transmission gear 93 between be in transmission connection by the first belt 94 and the second belt 95 respectively.Upper pressure handle fixture can be adjusted and highly be fixed on main body bearing, its structure that can adjust height for being provided with adjusting hole 62 on upper pressure handle fixture, in adjusting hole, be provided with adjusting bolt 63, the adjustment of height is realized in the fixed position by adjusting bolt in adjusting hole.
The middle part of upper pressure handle 5 extends to form the teat 51 of triangular shape downwards, this teat can rotate and be fixed on pressure handle fixture 6, on this, the upper end of pressure handle fixture is U-shaped, and this turntable can adopt bearing pin 53 that upper pressure handle is rotatably fixed in the U-shaped upper end of handle fixture 6.Tension spring 10 is located between pressure handle and upper pressure handle fixture, and this tension spring has makes pressure handle one end close pulling force of pressure handle fixing base direction on this.In upper pressure handle upper end, corresponding tension spring position is provided with the screw 53 for pushing this tension spring, can be used for regulating the pulling force of tension spring.
When detection, first upper pressure handle 5 is depressed, as little in circle product to be detected mold insert is positioned over to first, second wheel 41, between 42, then unclamp pressure handle 5, because the pulling force of tension spring 10 will make upper pressure handle 5 remain the power of extruding product to be detected, then use hand fixed handle 82, drive handwheel 81 to rotate, handwheel 81 rotates and drives the first transmission gear 91 to rotate, this first transmission gear 91 drives the second transmission gear 92 and the 3rd transmission gear 93 to rotate by the first belt 94 and the second belt 95 respectively again, and the second transmission gear and the 3rd transmission gear respectively fixed cover be located at first, second wheel 41, outside 42 one end, therefore handle 82 shakes handwheel 81 and will drive first, second wheel 41, 42 rotate respectively, simultaneously drive be placed in this first, product to be measured on second wheel rotates together, then clock gauge is adjusted to the position that can detect concentricity and carried out concentricity detection, if the distance of clock gauge is inadequate, can adjust the position of the fixing backing plate 20 of clock gauge on worktable, if distance is enough, only need to regulate the fine adjustment screw of clock gauge.In addition, if detect less internal diameter concentricity, replaceable little clock gauge detection head can easily detect.
This pick-up unit can be adjusted according to the size of product the height of upper pressure handle fixture, and the specification of testing product cylindrical can be from 1.0-10.0mm, and length is equal can detection in 17mm.
