Abstract
The utility model discloses an instrument is detected in thrust tile thermometer hole comprises supporting pad, axial -position screw, the cover that expands, spring, dabber, measuring joint, the straightness detection ruler that hangs down, installation dismantlement cover etc.. The bottom sprag that the instrument adopted in the hole, two sections conical surfaces are designed to the spindle, add bottom cover and the tip cover that expands that expands it on, expand the cover through two and accomplish the location of dabber in the hole, and the center of dabber be the center of measured hole promptly like this, through to the dabber center and the measurement of need the partial morpheme public affairs of measurement looking into the index, accomplishes required measured data's measurement. Convenient operation is swift for this kind of instrument, and reasonable in design is a new detection means.
Description
Technical field:
This utility model relates to a kind of propulsion tile of waterwheel generator thermometer hole detection instrument.
Background technology:
When building site needs to be adjusted thrust bearing shoe valve; the foundation adjusting thrust bearing shoe valve is the running temperature (being called for short watt temperature) with reference to thrust bearing shoe valve; and the unit thrust bearing shoe valve temperature difference and adjustment process show; RTD installing mode and RTD position of mounting hole concordance are not effectively controlled; watt temperature measurement error is bigger; cannot effectively carry out the adjustment of thrust bearing shoe valve; must first solve a watt problem for temperature measurement concordance difference; need thrust bearing shoe valve RTD hole is checked; guarantee the concordance of unit thrust bearing shoe valve RTD hole site, develop RTD hole and check specific purpose tool.RTD installation hole is the bottom outlet in the end thread hole using fluted drill processing, it is desirable to measure the perpendicularity of screwed hole and the axiality of its bottom outlet and thread Pilot hole and thrust bearing shoe valve.Determine the actual installation position of RTD according to measurement result, calculate the actual temperature that thrust bearing shoe valve runs.
Summary of the invention:
The purpose of this utility model is open a kind of Thrust-vectoring nozzle meter hole detection tool construction, and it has convenient to operation, the measurement result feature accurately of measurement.The normal use of thrust bearing shoe valve will not be impacted by this structure.Can greatly facilitate detection, the adjustment work for building site thrust bearing shoe valve provides foundation.nullThe technical solution of the utility model is: a kind of Thrust-vectoring nozzle meter hole detection instrument，By supporting pad (1)、Axial screw (2)、Bottom expansion set (3)、Spring (4)、Mandrel (5)、End expansion set (6)、Measure joint (7)、Detection rule for verticality (8)、Installing/dismounting set (9)、Cylinder pad (10)、M6 nut (11) composition axial screw (2) is by supporting pad (1)、Bottom expansion set (3)、Spring (4) is connected to the tapered portion of mandrel (5) one end and forms detection instrument location bottom tested gaging hole and ejecting structure，End expansion set (6) is enclosed within another end cone section of mandrel (5) and forms detection instrument in detected bore ends position portion，Measure joint (7) to be connected with tested screwed hole，Detection rule for verticality (8) contacts with thrust bearing shoe valve tiling and abuts in mandrel (5) and stretches out on the face of cylinder of tested gaging hole.
Operation principle:
Thrust-vectoring nozzle meter hole detection instrument is made up of mandrel, expansion set, measurement joint etc..Owing to detected hole dimension size is uncertain, two conical surfaces are processed on mandrel, end expansion set and bottom expansion set are with gap, two expansion set stress swellings in hole, so that the center of mandrel is consistent with the center of tested gaging hole, if so detecting core shaft and detected bore ends screw thread axiality and with the perpendicularity of thrust bearing shoe valve watt body.Between mandrel and bottom expansion set install spring formed ejecting structure, make Data Detection complete after can easily from hole take out.End expansion set is completed it by installing/dismounting set and is installed on dismounting.There is error owing to measuring, take repetitive measurement multi-group data to calculate its meansigma methods as testing result.
Technique effect:
1, can complete to be processed by fluted drill diameter is little and the detection of the concrete numerical value of Form and position error index such as axiality between thread Pilot hole and screwed hole that the degree of depth is big, this is that existing general measurer cannot complete.
2, the adjustment work enabling thrust bearing shoe valve smoothly completes, and the adjustment work for thrust bearing shoe valve provides reliable data support.
3, mandrel designs with the structure of expansion set and takes the scheme of repeatedly multi-group data acquisition process has reached testing result purpose accurately.
4, installation makes tool operation convenient and swift with ejecting structure.

Detailed description of the invention
nullThrust-vectoring nozzle meter hole detection instrument as shown in drawings，By supporting pad 1、Axial screw 2、Bottom expansion set 3、Spring 4、Mandrel 5、End expansion set 6、Measure joint 7、Detection rule for verticality 8、Installing/dismounting set 9、Cylinder pad 10、M6 nut forms，Two sections of conical surfaces are designed on mandrel 5，Bottom expansion set 3 is contained in bottom mandrel 5 at the conical surface，And spring 4 is contained between bottom expansion set 3 and mandrel 5 and is easy in hole, to take out instrument，Mandrel 5 end processes screwed hole，By axial screw 2, supporting pad 1 is connected with mandrel 5，As in measured hole bottom support，Above-mentioned installation is partially loaded in measured hole，Use installing/dismounting set 9 by the mandrel 5 opposite side conical surface in end tapered sleeve 6 load hole，By installing/dismounting set 9 taking-up，M6 nut 11 is installed in mandrel 5 end，Pressure M6 nut 11 makes part swelling in hole in load hole gently，So center of mandrel 5 is the center of measured hole，Use and measure joint 7、The axiality with mandrel 5 measured by detection rule for verticality 8 and screw micrometer and perpendicularity can complete the measurement of measured hole and the axiality perpendicularity in its end thread hole，Same index is carried out different directions repetitive measurement，And measurement result processed be required measurement result.The taking-up of instrument is contrary with loading order, is taken out by end expansion set 6 first by installing/dismounting set 9, if the difficulty of taking-up, cylinder pad 10 need to be used to eject installing/dismounting set 9 or mandrel 5 as support.
