Embodiment
For innovation and creation content, the Characteristic of the invention can be understood further, hereby exemplify following examples, be described in detail as follows:
As illustrated in fig. 1 and 2,
A kind of deep hole casing Endoporus measuring device, comprise dial gauge 1, the top of dial gauge is provided with the adjusting pole 2 of gantry shape, the top spiral of adjusting pole is connected with adjusting lever 3, the sleeve of dial gauge bottom is embedded in adapter piece 4, adapter piece is stretched out in the lower end of the sounding rod 5 of lower cartridge, adapter piece is the cylindrical shell of up/down perforation, the sidewall of adapter piece has the threaded hole perpendicular to adapter piece axis, adapter piece is threaded by the external thread part of threaded hole with intermediate supports assembly, intermediate supports assembly comprises connecting link 7, one section of connecting link is connected with adapter piece by screw thread, connecting link is slidably mounted in slip cap 8, the other end of slip cap is fixedly connected with elastic support 9.The lower slide of adapter piece is inserted in the through hole on elastic support first top, sounding rod is set with spiral compression spring 10, the lower end of spiral compression spring is against on the upper surface bottom elastic support first, lower surface bottom elastic support first is the curved surfaces protruded downwards, and the lower surface bottom elastic support first is provided with and supports salient point 11;
The other end of intermediate supports assembly is connected with elastic support, the upper end of elastic support is provided with upper support bar 12, the lower end of elastic support is provided with spiral compression spring 10, the lower end of spiral compression spring is against on the upper surface bottom elastic support second 13, lower surface bottom elastic support second is the curved surfaces protruded downwards, and the lower surface bottom elastic support second is provided with and supports salient point 11;
Intermediate supports assembly is also provided with auxiliary lamp 14 and camera 15, auxiliary lamp and camera are arranged on connecting link by cutting ferrule 16, and camera is electrically connected with display device (display device is not shown in FIG.) by lead-in wire 17.The camera of the present embodiment is MINI-3010CP4 (SN:2013111747) model of Sony Corporation; display device is 7 of TOWIN company " TFTMONITOR L7009 model, but the protection domain of this patent is not limited to camera and the display device of above-mentioned brand and model.
The operating principle of the invention is:
During use, if when measuring the consistent endoporus of internal diameter, so need the adjusting lever adjusted on the adjusting pole on dial gauge top, adjusting lever top is consistent to the top of the distance of intermediate supports assembly and upper support bar to the distance of intermediate supports assembly.If need to adjust the length of supporting component, so also should adjust the length of intermediate supports assembly, unclamp lock sleeve 18, make connecting link telescopic slide in slip cap to suitable length, and then lock lock sleeve, to adapt to the hole measuring of different depth.
A copper cash is put into as traction rope from the other end of casing; After dial gauge and elastic support install, after connecting traction rope, put into casing, slow movement, and make the top of the top of adjusting lever and upper support bar all hold out against the upper surface of endoporus, open auxiliary lamp, camera and display device, because auxiliary lamp and camera are all arranged on connecting link, so auxiliary lamp, distance between camera and dial gauge are constant, not by the impact of adjustment intermediate supports length component, dial gauge can be allowed all the time to be under certain brightness and shooting clear degree.Turnable elastic bearing second, the maximal value that user can observe the registration of dial gauge from display device is dial gauge registration herein.Because the invention adopts technique scheme, the first half of the first half of intermediate supports assembly, dial gauge and elastic support is utilized jointly to form a upwards uncovered right-angled U, the first half of deep hole casing Endoporus measuring device is against the top of endoporus, a rectangle can be formed, thus ensure that the parallel of intermediate supports assembly and interior axially bored line, and then ensure that inside surface vertical of dial gauge and endoporus.
If the endoporus of required measurement is stepped hole, the contact site of upper support bar is different from the radius of the contact site of adjusting lever, so can adjust the position of adjusting lever relative to adjusting pole, adjusting lever top is made to be the difference of two place's radiuses to the Distance geometry upper support bar of intermediate supports assembly to the distance difference of intermediate supports assembly, like this, still can ensure the parallel of the axis of intermediate supports assembly and endoporus to be measured, namely ensure that the vertical of dial gauge and endoporus.
Although be described the preferred embodiment of the invention above, but the invention is not limited to above-mentioned embodiment, above-mentioned embodiment is only schematic, be not restrictive, those of ordinary skill in the art is under the enlightenment of the invention, do not departing under the ambit that the invention aim and claim protect, a lot of form can also be made, such as: in the embodiment of this instructions, intermediate supports assembly can regulate its length by the mode of sliding, also intermediate supports assembly can be made the connecting link that cannot regulate length, these all belong within the protection domain of the invention.
