First gasket 91 is installed through two corresponding holes of body water conservancy diversion gasket locating pin hole 33 on first gasket 91 on this body block, for avoiding crossing the location, two hole size are great on first gasket 91, leave sufficient fit clearance, will again the columnar body 11 passes the run-off hole of first gasket and inserts the microcephaly end of main guiding hole 31, locating hole on the slice installation department 12 with body water conservancy diversion gasket locating pin hole 33 cooperation right above main guiding hole 31 is right microspur hole part 1 fixes a position, because part 1 adopts two locating pin location, consequently, in order to avoid taking place the location, inserts directly over main guiding hole 31 the locating pin of body water conservancy diversion gasket locating pin hole 33 adopts the diamond pin. After the positioning is finished, the micro-distance hole part 1 is compressed through the pressing plate 6, so that the situation that the measuring position of the micro-distance hole part 1 is not changed in the subsequent assembling, drainage and measurement fixing clamp and the measuring process is guaranteed. In order to avoid physical damage to the macro-hole component 1 caused by the pressing plate 6, a copper welding layer is arranged on the bottom surface of the U-shaped portion 61. And after the pressing plate 6 is clamped in place, the pressing plate is fixedly connected with the body block 3 through the connecting plate 62.
Referring to fig. 1, 2c, and 3c, after the positioning hole of the sheet-shaped mounting portion 12 is connected and positioned with the positioning pin hole 33 of the main guide flow gasket right above the main guide flow hole 31, the first oil injection hole 112 and the third oil injection hole 114 are ensured to be located right below the axis of the main guide flow hole 31.
The first gasket 91 can be made of a commercially available plastic king material which is resistant to high temperature, has small compression deformation and can realize sealing, so that end face sealing can be realized under the condition of ensuring small deformation, and the deformation amount is about 0.1mm through practical tests. The deformation amount is only less than the radius difference between the drainage hole and the spray hole.
The horizontal step surface 32 divides the end surface of the positioning block 4 into two parts, so that the flatness of each part plane can be ensured more easily, and in addition, the horizontal step surface 32 can also support the first gasket 91, thereby being beneficial to guiding in the assembling process.

When the drainage measurement fixing clamp is installed, the observation cavity 51 penetrates through the cylindrical body 11 to enable the end surface of the drainage measurement fixing seat to be attached to the end surface of the positioning groove 41, then the positioning seat 2 in the drainage measurement fixing clamp moves upwards along the positioning groove 41, the through groove 21 is attached to the lower surface of the cylindrical body 11 by the guiding of the positioning groove 41, thereby cladding the first oil jet 112, the second oil jet 113 and the third oil jet 114, then, the cylindrical body 11 is forced by a bolt screwed into the support plate force application threaded hole 52, so that the drainage measurement fixing jig is fixed to the cylindrical body 11, the position of the drainage hole corresponding to the oil injection hole of the macro-hole part 1 to be measured can be ensured, and the through groove 41 can be attached to the lower surface of the cylindrical body 11 without a gap.
The bottom surface of the bolt screwed with the force application threaded hole 52 of the support plate 5 can also be provided with a copper welding layer, so that physical damage to the micro-distance hole part 1 in the fastening process can be avoided.
The width of the positioning slot 41 may be 0.05-0.1mm larger than the width of the positioning seat 2, and the diameters of the first drainage hole 212, the second drainage hole 213, and the third drainage hole 214 may be 0.6-0.9mm larger than the diameters of the corresponding first oil spray hole 112, the corresponding second oil spray hole 113, and the corresponding third oil spray hole 114, respectively, so that after the through slot 21 is attached to the lower surface of the cylindrical body 11, the first drainage hole 212, the second drainage hole 213, and the third drainage hole 214 can respectively coat the first oil spray hole 112, the second oil spray hole 113, and the third oil spray hole 114. When the diameters of the first drainage hole 212, the second drainage hole 213, and the third drainage hole 214 are respectively 0.8mm larger than the diameters of the corresponding first oil spray hole 112, the corresponding second oil spray hole 113, and the corresponding third oil spray hole 114, the measurement requirements under most conditions can be met, and the machining can be facilitated.

Because the axes of the first drainage hole 212 and the third drainage hole 214 are arranged on the symmetry plane of the through groove 21 and have a certain included angle, the size of the positioning seat 2 is increased to ensure that the first drainage hole 212 and the third drainage hole 214 are respectively communicated with the corresponding oil spray holes of the macro-pitch hole part 1, the opening at the far end of the positioning seat 2 body has enough space, and independent drainage tubes which do not interfere with each other can be arranged, and can be welded on the positioning seat 2 body in advance as shown in fig. 3 c. For second drainage hole 213, it is only necessary to ensure that the ejected oil flows out smoothly, and the single-hole flow measurement of first drainage hole 212 and third drainage hole 214 is not affected, and therefore, by providing chute 42, the space requirement for the oil flowing out of second drainage hole 213 can be ensured.
A pipe joint may be welded in advance to the large end of the main flow guiding hole 31, which may facilitate connection of different flow detecting devices.
The method for measuring the flow of the micro-distance hole solves the actual problem that an accurate measurement result cannot be obtained due to the fact that the oil receiving pipe cannot lean against the orifice in the background technology. The flow detection of the small part micro-distance hole is realized, and the detection result is stable and accurate. The measuring clamp is simple to operate and convenient to observe.
