Abstract
The utility model provides a radiator boring symmetry degree detection tool comprising a tool main body and a detection pin shaft. The surface of the tool main body is provided with a groove and a circular through hole. The groove is tightly cooperated with a front radiator waveguide tube. When the front radiator waveguide tube is fixedly disposed in the groove, the bore hole of the front radiator waveguide tube faces the circular through hole, and is coaxial to the circular through hole. The radius of the circular through hole is equal to the radius of the bore hole plus the required tolerance, and the diameter of the detection pin shaft is equal to the diameter of bore hole. One end of the detection pin shaft facing the bore hole is provided with a chamfer. The radiator bore hole symmetry degree detection tool has advantages of simple convenient operation, and accurate fast measurement.
Description
Technical field
The present invention relates to a kind of symmetry checking device for hole site after the Boring of previous irradiation device assembly termination.
Background technology
At present, the previous irradiation device hole of detection after Boring is about the four sides symmetry of waveguide socket piece, to insert in the hole that detected part boring is good with the bearing pin of bore diameter coupling, and place it on a bloom just excessively coordinating with waveguide, guarantee to be adjacent to bloom groove surface below waveguide, then lever meter is fixed in the part of moving about of marking-out rule and fixes, adjust the height dimension of lever meter bulb and bearing pin upper surface, on the other hand waveguide is pressed on bloom, drag the marking-out rule that lever meter is housed, record the scale value of peak, then tested part reverse side is contained in the groove of bloom, be adjacent to surface of contact, measure the value of bearing pin upper surface peak with lever meter with same method, poor by the value of twice measurement, if difference is within the 0.15mm requiring, the symmetry of this direction hole site is qualified, turn 90 °, adjust the height of lever meter, continue to measure the value of side surface direction bearing pin peak, then reverse side is measured the measured value of another side bearing pin peak, twice measured value is poor, if difference is within the 0.15mm requiring, the symmetry of this direction hole site is qualified.Due to waveguide Width and thickness direction gap larger, parts measurement four times, lever meter height control twice, measured value calculates twice, complete qualified is pieces O.K., either direction is defective be defective.In addition, because have no idea to measure 45 ° of symmetries in direction, from formula 0.15(√ 2-1)/0.15*100%, both direction detects qualified part, and some also can overproof 40% in 45 ° of directions.Above-mentioned detection method is loaded down with trivial details, slow, expend bodily strength, easily make mistakes, and also unreliable.When detecting when hundreds thousand of such parts, muscle power to people, see that the eyesight etc. of lever meter pointer is all acid test, also greatly reduce detection efficiency and reliability.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of radiator bore hole symmetry and detect frock, when use, only need to be placed on and measure on flat board, the coupling groove hand of the waveguide of tested previous irradiation device being put into frock main body is tight, another hand pushes axial test pin measured hole, if bearing pin can insert in the hole, part is qualified, and bearing pin is inserted not enter, and part is defective.Simple to operation, measure accurate quick.
The technical solution adopted for the present invention to solve the technical problems is: comprise frock main body and detect bearing pin, described frock body surfaces has groove and manhole, groove and previous irradiation device waveguide closely cooperate, when current radiator waveguide is fixed in groove, the bore hole of previous irradiation device waveguide is towards manhole and coaxial with manhole, and the radius of manhole equals radius of bore and adds desired tolerance; The diameter of described detection bearing pin equals bore diameter, and detection bearing pin has chamfering towards bore hole one end.
The invention has the beneficial effects as follows: when the present invention uses, only need to be placed on and measure on flat board, the coupling groove hand of the waveguide of tested previous irradiation device being put into frock main body is tight, another hand pushes axial test pin measured hole, if bearing pin can insert in the hole, part is qualified, bearing pin is inserted not enter, and part is defective.Simple to operation, measure accurate quick.The present invention is mainly used in the symmetry check of hole site after the Boring of previous irradiation device assembly termination, can quick and conveniently check out exactly the symmetry of the hole site of part after Boring whether within the margin tolerance of regulation, especially in the situation that such number of spare parts of detection is huge especially, whether qualified the symmetry that use the present invention can detect the rear hole site of processing, sugared hole fast, is easily and accurately.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure, 1-frock main body, 2-detects bearing pin.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further described, the present invention includes but be not limited only to following embodiment.
The present invention is mainly made up of two parts: frock main body, detects bearing pin.The groove design of this frock body surfaces has rational gap, and previous irradiation device waveguide can be put into wherein and can double swerve.To be arranged on the position coaxial with bore hole for detection of the manhole of tested part hole site symmetry, the radius of manhole equals pore radius direction to expand 0.15mm.The diameter design that detects bearing pin can make it easily insert in tested hole and can not double swerve.After part installs, can insert smoothly in the hole of tested part by the concentric circle holes of frock main body if detect bearing pin like this, the symmetry tolerance of hole site all directions is in 0.15mm.It is whether qualified that the present invention can detect after previous irradiation device assembly bore hole the symmetry of hole site fast, easily and accurately.
Embodiment:
The present invention is made up of two parts: the frock main body 1 that symmetry detects and detection bearing pin 2.When installation, to detect bearing pin 2 chamfered end inwardly by illustrating a detection reference hole site that packs frock main body 1 into, and frock main body 1 is placed in ordinary flat, the hole of tested part is put forward, waveguide is put into the groove of frock main body 1, the surface of contact of above-below direction is adjacent to, with hand propelled detection bearing pin 2, if detect bearing pin 2 penetrate smoothly measured hole, the symmetry of part bore hole position is qualified, wear to enter be defective.
According to present detection method the tolerance of level and vertical direction can only be narrowed down to 0.1mm guarantee the part that detects of useful existing method be qualified, but like this due to dwindling of tolerance cause part difficulty of processing increase rolling up of overproof scrapped parts quantity.Using the design to detect bore hole symmetry, is directly the symmetry in hole to be measured, and can obtain the detection case of circumference all directions symmetry.Use the present invention only to need part to be close to main body grooving face, detection bearing pin one pushes away one and draws, can detect fast, easily and accurately the processing situation of hole site symmetry after the Boring of previous irradiation device termination, than traditional method, utilize the design can greatly improve detection efficiency and the accuracy of this kind of part, save a large amount of labours and time.
Claims (1)
