Abstract
The utility model discloses an integral testing scale for a skirting board of an equipment cabin of a motor train unit; the integral testing scale comprises a radian scale which is matched with the skirting board in shape, wherein a vernier A and a vernier D are respectively arranged in positions near two ends of the radian scale; a vernier B and a vernier C are arranged in parallel in a position near the middle of the radian scale; air hole measuring scale is arranged on the radian scale in a detachable manner; a magnifying glass is arranged on the radian scale in a detachable manner; as the verniers, the magnifying glass, the air hole measuring hole and the radian scale are integrated in the integral testing scale for the skirting board of the equipment cabin of the motor train unit, the integral testing scale can simultaneously test the geometry defect, the length tolerance and the gap of the skirting board and is simple and convenient to operate; and by adopting the integral testing scale, the numerical reading is visual and accurate, and the working efficiency is greatly improved.
Description
Technical field
The utility model relates to a kind of pick-up unit, particularly a kind of detection ruler of EMUs equipment compartment skirtboard.
Background technology
EMUs equipment compartment skirtboard is the vitals of motor-car equipment compartment, for hanging device under the car provides lateral protection, and its whole curved platy structure.The equipment compartment skirtboard detects and comprises that (VT) visual detection and size geometric shape detect.Visual detection is one of method of Non-Destructive Testing, and the visual detection of skirtboard mainly is meant utilizes the weld seam chi, and the three quarters of an hour is measured rule; Magnifieres etc. carry out Non-Destructive Testing to the weld seam on the skirtboard, and the content of detection comprises pore, crackle; Incomplete fusion; Lack of penetration, be mingled with the geometrical deviation of weld shape defective and weld seam.The safe class of the standard main reference weld seam of checking and accepting is checked and accepted according to the iso10042 defect rank.Physical dimension specifically refers to utilize slide calliper rule equal length survey instrument that skirtboard product whole radian and length are detected.The instrument that does not have a kind of specialty at present combines two kinds of detections.Existing detection technique is divided into three parts with the skirtboard check: the one, and VT detects, and uses the weld seam chi to detect the defective in weld heat-affected zone and the peripheral 30cm scope; The 2nd, utilize the kind of calliper length tolerance; The 3rd, combine to measure clearance between skirt panels with clearance gauge after utilizing a kind of aluminium sheet of specific arc to block male and fomale(M&F), observe the deflection that causes because of reasons such as welding heats.In the real work, outward appearance (VT) detects with the detection of physical dimension profile and is divided into different step, the operation more complicated, and detection efficiency is lower, and each item detection degree of correlation is not high, but each final association is closely related again.
To above-mentioned deficiency, a kind of testing tool of quicklook need be provided, can detect each index fast simultaneously, improve detection efficiency.
The utility model content
In view of this, the purpose of the utility model provides a kind of EMUs equipment compartment skirtboard one detection ruler, makes detection of skirtboard external form and weld inspection embody completion simultaneously by this one detection ruler, reaches convenient and detects, and is directly perceived, accurate, the purpose of increasing work efficiency.
The purpose of the utility model realizes through following technical scheme: a kind of EMUs equipment compartment skirtboard one detection ruler; Comprise the radian chi that shape and skirtboard adapt; Position near two ends on the radian chi is provided with move about the chi A and the chi D that moves about respectively, and the radian chi is set up in parallel move about the chi B and the chi C that moves about near the middle part.
Further, on the said radian chi pore dip stick is set removably;
Further, on the said radian chi magnifier is set removably.
The beneficial effect of the utility model: the EMUs equipment compartment skirtboard one detection ruler of the utility model; Move about chi, magnifier, pore dip stick and radian chi is set to one; Can detect geometrical defect, length tolerance and the gap of skirtboard simultaneously; Easy and simple to handle, reading is directly perceived, accurate, has improved work efficiency greatly.

Embodiment
Fig. 1 is the structural representation of the utility model; Fig. 2 is the user mode figure when measuring deformation; Fig. 3 is the user mode figure when surveying unfitness of butt joint; Fig. 4 is the user mode figure when surveying groove; Fig. 5 is the user mode figure when surveying preweld interval; Fig. 6 is the user mode figure when surveying width; Fig. 7 is the user mode figure when surveying pore.
As shown in the figure: the EMUs equipment compartment skirtboard one detection ruler of present embodiment; Comprise the radian chi 1 that shape and skirtboard adapt; Position near two ends on the radian chi is provided with move about the chi A2 and the chi D3 that moves about respectively, and the radian chi is set up in parallel move about the chi B4 and the chi C5 that moves about near the middle part.
The move about method of application of chi of the each several part of present embodiment EMUs equipment compartment skirtboard one detection ruler is specially:
1, measure deformation: as shown in Figure 2, the end D chi value that detection ruler one end blocks skirtboard is 0, utilizes the A chi to block the skirtboard other end, can measure the deflection of skirtboard.Like D chi chucking, A, D chi reading and be the deflection of skirtboard so.
2, survey unfitness of butt joint: as shown in Figure 3, detection ruler is close to skirtboard, utilizes B chi and C chi to block the weld seam two ends and measures height value h
1And h
2, both differences promptly are the unfitnesses of butt joint of weld seam.
3, survey groove: as shown in Figure 4, B chi two ends are respectively 30 ° and 45 °, and C chi one end is 60 °.
4, survey preweld interval: as shown in Figure 5, with the gap before the other end insertion welding of C chi, can survey the gap width before welding.
5, survey width: as shown in Figure 6, detection ruler one end blocks skirtboard (near the D chi), and whether utilize width value near the A chi can record the skirtboard width suitable.
6, survey pore: as shown in Figure 7, dismounting pore dip stick utilizes the pore dip stick can record the pore opening or the crack length of face of weld.
The EMUs equipment compartment skirtboard one detection ruler of the utility model; Move about chi, magnifier, pore dip stick and radian chi is set to one, can detect geometrical defect, length tolerance and the gap of skirtboard simultaneously, and be easy and simple to handle; Reading is directly perceived, accurate, has improved work efficiency greatly.
As further improvement, on the said radian chi pore dip stick 6 is set removably to the foregoing description.The pore dip stick is set can directly measures skirtboard face of weld pore, convenient and swift.
As further improvement, on the said radian chi magnifier 7 is set removably to the foregoing description.Magnifier is set is convenient to observe and watches unclear surface imperfection than spilehole or Other Meat, accurately convenient.
Explanation is at last; Above embodiment is only unrestricted in order to technical scheme of the present invention to be described; Although the present invention is specified with reference to preferred embodiment; But those of ordinary skill in the art makes amendment to technical scheme of the present invention or is equal to replacement, and does not break away from the aim and the scope of technical scheme of the present invention, and it all should be encompassed in the middle of the claim scope of the present invention.
