A measuring pointer of the dial indicator is inserted into an inner hole of the fixed outer sleeve; the spring and the backing plate are sleeved on the measuring pointer of the dial indicator and is positioned in the fixed outer sleeve; the fixed inner sleeve is sleeved on the measuring head and is in threaded connection and fixation with the fixed outer sleeve; the plane end of the backing plate is horizontally placed on the end surface of the measuring head; and the spring is positioned between a groove of the backing plate and a groove on the inner end surface of the fixed outer sleeve. The calibration sleeve in the measuring device is specially used for calibrating the measuring device. The measuring device has the advantages of simple structure, low cost, convenience in measurement, accurate detection result and safe and reliable implementation effect; and the A size measurement can be effectively solved. Meanwhile, the repair rate and the scrape rate of products can be effectively reduced, and the quality and economic benefits of products are improved.

Description

A kind of measurement mechanism that is used for the pipe seal inner conical surface
Technical field
The utility model relates to a kind of measurement mechanism, specifically, relates to a kind of measurement mechanism that is used for the pipe seal inner conical surface.
Background technology
The bevelled sealing surface of pipe adapter is important working position, in traditional processing, often adopts calliper etc. relatively to measure and judges whether it is qualified.When measuring with calliper, the go side of calliper, not-go-end are stuck on the bevelled sealing surface of workpiece, and by range estimation, the bevelled sealing surface of go side, not-go-end and the workpiece of observation calliper and the gap of end face compare measurement; This kind method can not quantize the A value, and accuracy is not high.And being used for the important conduit of specific occasion and purposes for some, this is not enough.Therefore, the needs use is a kind of can directly measure the measurement mechanism of sealing cone position.
The utility model content
The technical problems to be solved in the utility model provides the measurement mechanism of the direct detector tube joint sealing of a kind of energy inner conical surface size.
This measurement mechanism comprises dial gauge, fixed jacket tube, milled screw, spring, backing plate, gauge head, fixing inner sleeve.The measurement pointer of dial gauge inserts in the endoporus of fixed jacket tube, spring and backing plate are sleeved on the measurement pointer of dial gauge, be arranged in the fixed jacket tube, fixedly inner sleeve is sleeved on the gauge head, be threaded fixing with the fixed jacket tube, the planar ends of backing plate lies on the end face of gauge head, and spring is between the inner face groove of the groove of backing plate and fixed jacket tube.
This measurement mechanism is simple in structure, cost is low, measurement is convenient, testing result is accurate, implementation result is safe and reliable, can solve the problem of A dimensional measurement effectively.Can effectively reduce simultaneously the repair rate and the scrappage of product, improve the quality and the economic benefit of product.
Description of drawings
Fig. 1 is the structural representation of the measurement mechanism of the utility model pipe seal inner conical surface;
Fig. 2 is the calibration structure synoptic diagram of the measurement mechanism of the utility model pipe seal inner conical surface;
Embodiment
Can find out that from Fig. 1 and Fig. 2 this measurement mechanism comprises fixed jacket tube 2, milled screw 3, spring 4, backing plate 5, gauge head 6, fixing inner sleeve 7.Its structure is: the measurement pointer of dial gauge 1 inserts in the endoporus of fixed jacket tube 2, spring 4 and backing plate 5 is put into fixed jacket tube 2, and be sleeved on the measurement pointer of dial gauge 1.Fixedly inner sleeve 7 is sleeved on the gauge head 6, and it is fixing to be threaded with fixed jacket tube 2 then, and spring 4 and backing plate 5 are fixed in the fixed jacket tube 2.The planar ends of backing plate 5 lies on the end face of gauge head 6, and spring 4 is sleeved on to be measured on the pointer, and between the inner face groove of the groove of backing plate 5 and external fixation sleeve 2.This measurement mechanism is with the imaginary diameter D of the pipe adapter 9 theoretical potted lines design base point as measurement mechanism, confined state when coming simulative tube joint 9 actual uses by gauge head 6 and pipe adapter 9 inner conical surfaces 8 are tangent, by gauge head 6 and the fixedly relative displacement of inner sleeve 7, directly read the position dimension A of potted line from the dial gauge 1.In measurement, can change corresponding gauge head 6 according to pipe adapter 9 inner conical surfaces 8 different sizes, and the fixedly inner sleeve 7 that matches with gauge head 6.The spherical diameter of gauge head 6 is SR 3.3~13.5mm, and fixedly inner sleeve 7 is φ 7~28mm with the small aperture that gauge head 6 matches, and macropore diameter is φ 9~30mm.
See Fig. 2, the calibrating mode of this measurement mechanism is to adopt the limited mouth 10 of the calibration sleeve 11 equate with the imaginary diameter D of pipe adapter 9 theoretical potted lines to limit the prone displacement of bulb of gauge head 6, and with the zero point of this position as measurement mechanism.Calibration sleeve 11 and gauge head 6, fixedly inner sleeve 7 supporting uses, the diameter of bore of calibration sleeve 11 is φ 6.5~26.6mm.When measurement mechanism is in null position, the milled screw on the fixed jacket tube 23 is tightened with fixing dial gauge 1.
Before measurement, the angle of pipe adapter 9 inner conical surfaces 8 to be measured should detect qualified after, carry out the measurement of potted line again to the position dimension A of end face.During measurement, the cleaning measurement mechanism uses calibration sleeve 11 with 1 zero clearing of dial gauge in the measurement mechanism more earlier.
The concrete steps that adopt this measurement mechanism to measure:
1) cleaning piece surface;
2) fixedly inner sleeve 7 end faces of the measurement mechanism after will calibrating are close to pipe adapter 9 end faces, by the pressure of spring 4 spherical surface and pipe adapter 9 inner conical surfaces 8 of gauge head 6 are close to;
3) directly read the A value from dial gauge 1.
Because the position of potted line is in the stage casing of inner conical surface 8, conventional measuring method can't directly detect it.Compared with the prior art, this measurement mechanism can be measured by the direct fast potted line size A to pipe adapter 9, directly reads the size of A value; And can directly measure, help just revising in product processed to product processed on the lathe.
