Description
Technical field
The present invention relates to pneumatic detecting devices technical field, be specifically related to aerodynamic port deep investigation device.
Background technology
The qualification rate of hole depth is detected general manually to use gage measuring, but this uses when being only applicable to negligible amounts, aborning large batch of hole depth qualification rate detection can not rely on manual detection, the structure of the detecting device of current hole depth is complicated, cost is high, and applicability is low.
Summary of the invention
Technical matters to be solved by this invention is for above-mentioned defect, provides aerodynamic port deep investigation device, and structure is simple, and accurately can detect hole depth and also can detect by the fluctuation range of hole depth, applicability is stronger.
The technical scheme that the present invention solves the employing of its technical matters is as follows:
Aerodynamic port deep investigation device, comprise cylinder, sounding rod, running ga(u)ge, controller, described cylinder piston rod front end is provided with connecting plate, described sounding rod shaft bottom is connected with connecting plate front end, sounding rod top is provided with shields and sustain plate, shield and sustain plate Upper vertical to arrange, bottom bending is slidably connected with sounding rod, shield and sustain the plate face relative with sounding rod and be provided with two microswitches, sounding rod shaft corresponding between two microswitches is bulge-structure, bulge-structure can touch with the shell fragment of microswitch, microswitch is connected with described controller, described running ga(u)ge is arranged on piston rod bottom, running ga(u)ge level height is adjustable, activating sensor is provided with bottom described sounding rod, activating sensor is connected with controller.The height of running ga(u)ge has been set up in advance according to the size in hole, the range size distance of microswitch being adjusted to hole depth fluctuation is identical, make the movement travel of cylinder piston rod consistent with hole depth, when piston rod movement is to running ga(u)ge place under normal circumstances, activating sensor bottom sounding rod with contact to controller feedback signal at the bottom of hole, controller judges in conjunction with the detection signal of microswitch, the degree of depth in hole is too dark or too shallow all can touch corresponding microswitch, signal feedback is shown testing result to controller by microswitch, the hole being in the fluctuation degree of depth can be detected, it is convenient to measure, reliably, if Kong Taishen piston rod is blocked by running ga(u)ge, touch switch touches and then sends the defective signal of hole depth to controller less than not detecting signal at the bottom of hole.
Further, the number of described microswitch can also be one, microswitch and the shell fragment of defending eastern switch corresponding with sounding rod bulge-structure can touch with bulge-structure, microswitch is to shield and sustain the position on plate adjustable, microswitch is adjusted to hole depth qualified time height, piston rod movement is to when being blocked by running ga(u)ge, activating sensor bottom sounding rod touches at the bottom of hole and sends signal, microswitch contacts with sounding rod bulge-structure and sends signal simultaneously, only have controller to be subject to the degree of depth of the telltale hole of activating sensor and microswitch just qualified simultaneously, accomplish accurate detection.
Further, when detecting the hole depth of certain limit, described activating sensor and microswitch asynchronous controlling work, and when accuracy detection hole depth, touch switch and microswitch work simultaneously, and the external feeder of described cylinder is also provided with gauge tap.Described controller is provided with display, the qualified and defective information of the display detect aperture degree of depth.
The invention has the beneficial effects as follows: adopt such scheme, can do accurate detection, also can detect the hole depth qualification rate of certain fluctuation range hole depth qualification rate, structure is simple, and detect fast, applicability is stronger.
