Abstract
The utility model discloses a special tool for detecting a proximity switch. The special tool is mainly formed by a U-shaped aluminum profile guide rail, a standard calibrated scale arranged at the bottom of the guide rail, a DC voltage stabilization power supply, a resistor and a light-emitting diode. The DC voltage stabilization power supply is connected in series with the resistor and the light-emitting diode; and the proximity switch to be detected is connected with the light-emitting diode and the DC voltage stabilization power supply. The standard calibrated scale is arranged at the bottom of the guide rail, and the performance of the proximity switch can be rapidly detected based on the scales recorded when the light-emitting diode is on and off; and therefore, the special tool, on one hand, improves detection accuracy of the proximity switch and, one the other hand, improves the detection efficiency greatly.
Description
Technical field
The utility model relates to a kind of special tooling of checking approach switch.
Background technology
In inspection approach switch KHC90, the accuracy of each technical indicator is the very important project of the examination and test of products, at present, also there is no a kind of special tooling of quick test approach switch.For accurately checking this inspection frock of these Project design.
Summary of the invention
Technical problem to be solved in the utility model is a kind of special tooling of fast, accurately checking approach switch KHC90 of design.
In order to solve the problems of the technologies described above, the utility model provides a kind of special tooling of checking approach switch, described special tooling is to be mainly made up of U-shaped aluminium section bar guide rail processed, the master scale chi, DC voltage-stabilizing power supply, resistance and the light emitting diode that are positioned at guide rail bottom, described DC voltage-stabilizing power supply and resistance and light emitting diode are connected in series, and approach switch to be tested is connected with light emitting diode and DC voltage-stabilizing power supply.
The beneficial effects of the utility model are:
Master scale chi is placed in guide rail bottom by technical solutions of the utility model, adopt the go out scale write down of one bright one of light emitting diode can check fast the performance of approach switch, the accuracy that therefore this special tooling improves inspection approach switch has on the one hand improved checkability on the other hand greatly.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Brief description of the drawings
Fig. 1 the utility model special tooling structural representation.
Reference numeral annotation: 1, approach switch to be tested; 2, magnet steel; 3, U-shaped aluminium section bar guide rail processed; 4, master scale chi.
Embodiment
As shown in Figure 1, the utility model provides a kind of special tooling of checking approach switch, it is characterized in that, described special tooling is to be mainly made up of U-shaped aluminium section bar guide rail 3 processed, the master scale chi 4, DC voltage-stabilizing power supply, resistance and the light emitting diode that are positioned at guide rail bottom, described DC voltage-stabilizing power supply and resistance and light emitting diode are connected in series, and approach switch 1 to be tested is connected with light emitting diode and DC voltage-stabilizing power supply.Approach switch 1 to be tested is placed on magnet steel 2 guide rail 3 far away, then approach switch 1 to be tested is slowly slided and approaches magnet steel 2 on guide rail 3.In the time of lumination of light emitting diode, write down the scale that approach switch head is corresponding.Now approach switch is slided away from magnet steel 2, in the time that light emitting diode is no longer luminous, write down equally scale corresponding to approach switch head to be tested.The go out scale write down of one bright one of this light emitting diode is this approach switch action and the accurate calibration that discharges.
The utility model protection domain is not limited to above-described embodiment, and all apparent technology distortion of doing according to the utility model know-why, within all falling into protection domain of the present utility model.
