Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is done and describes clearly and completely further.
Embodiment
Shown in composition graphs 1 and Fig. 2: the device of a kind of Rapid Screening metalwork groove/opening height defect that the present embodiment provides, comprise base 1 and conducting metal platform 2, described conducting metal platform 2 is provided with detection zone 21, in described detection zone 21, is provided with some metal floating contacts 3; The conducting metal platform 2 being positioned at detection zone 21 periphery is provided with some bi-colour LEDs 4; The insulation of described metal floating contact 3 is located on the conducting metal platform 2 in detection zone 21, and is arranged with spring 5 on the position that it is positioned at below conducting metal platform 2, and the bottom of described spring 5 is inconsistent with the conductive metal sheet 6 be located on base 1 surface; Described conductive metal sheet 6 offers perforation 61, described base 1 offers the screw 8 be connected with described perforation 61, in described screw 8, be provided with spacing metal contact 9, described metal floating contact 3 can be inconsistent through perforation 61 and spacing metal contact 9; Be positioned at conductive metal sheet 6 immediately below same metal floating contact 3 and spacing metal contact 9 is electrically connected with same bi-colour LED 4 respectively by plain conductor, described bi-colour LED 4 is electrically connected by the positive pole of plain conductor with power supply 7, and the negative pole of described power supply 7 is electrically connected with conducting metal platform 2 by plain conductor.
In its natural state: the peak of described metal floating contact 3 is positioned at the upper limit position of the groove/opening height to be measured of metalwork 10 to be checked, and (that is: the upper end of described metal floating contact 3 is higher than the conducting metal platform 2 of detection zone 21, and height difference △ h is between the two the limits of error value of the groove/opening height to be measured of metalwork to be checked), the lower end of described metal floating contact 3 is the maximum permission upper limit error amount of the groove/opening height to be measured of metalwork 10 to be checked and maximum permission lower limit error amount sum apart from the distance values d on spacing metal contact 9 top.
Preferably: described metal floating contact 3 comprises top 31, middle part 32 and bottom 33, and the middle part 32 between top 31 and bottom 33 forms boss, thus it is spacing to reach described spring 5.Between the contact surface of described top 31 and conducting metal platform 2, be provided with insulation sleeve 11, between the contact surface of described middle part 32 and conducting metal platform 2, be provided with felt pad 12, to avoid the formation of short circuit, affect test accuracy.Described spacing metal contact 9 is threaded connection and is arranged in described screw 8, to facilitate the position installing and regulate spacing metal contact 9.Described bi-colour LED 4 selects LED, to realize energy-conservation and to increase the service life.
The operation principle of device described in the utility model is as follows:
Due in its natural state, the peak of described metal floating contact 3 is positioned at the upper limit position of metalwork 10 to be checked groove/opening height to be measured, and the lower end of described metal floating contact 3 is the maximum permission upper limit error amount of metalwork 10 to be checked groove/opening to be measured height and maximum permission lower limit error amount sum apart from the distance values on spacing metal contact 9 top; Therefore, if the height of groove/opening to be measured exceeds maximum permission upper limit position, then when metalwork 10 to be checked is placed on detection zone 21, groove/opening to be measured cannot touch the peak of metal floating contact 3, thus also just cannot this metal floating contact 3 of conducting and the circuit loop between spring 5, conductive metal sheet 6, bi-colour LED 4, power supply 7 and conducting metal platform 2, the bi-colour LED 4 in this circuit also just can not be made to light; If the height of groove/opening to be measured (that is: between the maximum permission upper limit and maximum permission lower limit) in the error range of regulation, then when metalwork 10 to be checked is placed on detection zone 21, tested point will touch the peak of metal floating contact 3, thus this metal floating contact 3 of conducting and the circuit loop between spring 5, conductive metal sheet 6, bi-colour LED 4, power supply 7 and conducting metal platform 2, the bi-colour LED 4 in this circuit is lighted (such as: bright green) with a kind of color; If the height of groove/opening to be measured exceeds maximum permission lower position, then when metalwork 10 to be checked is placed on detection zone 21, tested point will press down the peak of metal floating contact 3, make the lower end of metal floating contact 3 and spacing metal contact 9 top inconsistent, thus make this metal floating contact 3 and the circuit loop conducting between spacing metal contact 9, bi-colour LED 4, power supply 7 and conducting metal platform 2, the bi-colour LED 4 in this circuit is lighted with another kind of color (such as: red).
During actual use, can according to the installation site of the size and shape adjustment metal floating contact 3 of metalwork 10 to be checked and quantity.
Visible in sum: to use device described in the utility model, only metalwork to be checked need be placed on detection zone, by the change of viewing lamp color, can intuitive judgment metalwork groove/opening to be checked height dimension whether existing defects, not only simple to operate, quick, and structure is simple, affect by extraneous factor little, testing result accurately and reliably, accuracy of detection is controlled; Therefore, device described in the utility model can be used for carrying out Rapid Screening to the groove/opening height dimension defect of metalwork in enormous quantities, to ensure that the product mass-energy of sold metalwork meets high accuracy matching requirements, has obvious industrial application value and conspicuousness progress.
Finally be necessary to herein means out: the foregoing is only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.
