Abstract

A kind of conduit enlarging port wall thickness calliper, belongs to test, field of measuring technique.The conduit enlarging port wall thickness calliper includes fixed seat and measurement head;The fixed seat is provided with two axially extending bores of parallel arrangement, and minimum wall thickness (MINI W.) is H between two axially extending bores;The measurement head includes the first measurement head and second measurement head two parts, and first measurement head and the second measurement head are cylindrical structure, is arranged on interference fit in the axially extending bore of fixed seat.The utility model has the characteristics of simple in construction, easy to operate, not only ensure that the reliability of testing result, and improves operating efficiency.

Description

A kind of conduit enlarging port wall thickness calliper
Technical field
A kind of calliper for the detection of conduit enlarging port wall thickness is the utility model is related to, belongs to test, e measurement technology neck Domain.
Background technology
As shown in Figure 1, a kind of conduit detail 1 being applied in precision instrument and equipment fluid pressure line, at its termination position Provided with horn-like enlarging 1-1, according to relevant technical requirements, the enlarging port wall thickness minimum value of the conduit detail 1 is H, therefore Before the assembling of conduit detail 1, its enlarging port wall thickness need to be detected.Because the enlarging inwall of conduit detail 1 is circular conical surface Structure, and enlarging port wall thickness dimension is smaller, has that measurement accuracy is low, inconvenient for operation etc. lacks using the survey tool of routine Fall into, be not only difficult to ensure that the reliability of testing result, and operating efficiency is relatively low.
Utility model content
The purpose of this utility model is the drawback for prior art, there is provided a kind of simple in construction, easy to operate leads Pipe enlarging port wall thickness calliper, to ensure the reliability of testing result, improve operating efficiency.
To achieve the above object, the utility model adopts the following technical scheme that:
A kind of conduit enlarging port wall thickness calliper, it includes fixed seat and measurement head;The fixed seat is provided with parallel arrangement Two axially extending bores, minimum wall thickness (MINI W.) is H between two axially extending bores;The measurement head includes the first measurement head and the second measurement Head two parts, first measurement head and the second measurement head are cylindrical structure, and fixed seat is arranged on interference fit Axially extending bore in.
Above-mentioned conduit enlarging port wall thickness calliper, first measurement head and the second measurement head are staggeredly arranged vertically, the One measurement head and second measurement end surface spacing L >=1mm.
Above-mentioned conduit enlarging port wall thickness calliper, the fixed seat is rectangular parallelepiped structure, between two neighboring lateral surface Arc-shaped transitional surface is set, and axial both ends set the transition conical surface.
The beneficial effects of the utility model are:
The utility model is a kind of conduit enlarging port wall thickness calliper, and it is provided with two axial directions of parallel arrangement in fixed seat Through hole, and make between two axially extending bores minimum wall thickness (MINI W.) be H, at the same the utility model in axially extending bore with interference fit The measurement head of two cylindrical structures is installed, thereby ensures that the spacing of two measurement head end vertical axis directions and relevant skill The enlarging port wall thickness minimum value of conduit detail 1 of art requirement is consistent, can when being detected to conduit detail enlarging port wall thickness Between conduit detail enlarging port is caught in into two measurement cephalic pars, by being caught in the observation of state to it, conduit detail is judged Whether enlarging port wall thickness meets the requirements;First measurement head and the second measurement head are also staggeredly arranged by the utility model vertically, The first measurement head and second is set to measure end surface spacing L >=1mm, therefore the positioning for measured workpiece of being more convenient for, so as to further It ensure that the reliability of testing result.In a word, the utility model has the characteristics of simple in construction, easy to operate, not only ensure that The reliability of testing result, and improve operating efficiency.

Embodiment
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
Referring to Fig. 2, Fig. 3, conduit enlarging port wall thickness calliper 2 described in the utility model includes fixed seat 2-1 and measurement Head;The fixed seat 2-1 is rectangular parallelepiped structure, and arc-shaped transitional surface is set between two neighboring lateral surface, and axial both ends are set The transition conical surface, two axially extending bores of parallel arrangement are provided with fixed seat 2-1, minimum wall thickness (MINI W.) is H between two axially extending bores; The measurement head includes the first measurement head 2-2 and second measurement head 2-3 two parts, the measurements of the first measurement head 2-2 and second Head 2-3 be cylindrical structure, with interference fit installed in fixed seat 2-1 axially extending bore in, the first measurement head 2-2 and Second measurement head 2-3 is staggeredly arranged vertically, the first measurement head and second measurement end surface spacing L >=1mm.
, can be by conduit when enlarging 1-1 port wall thickness of the utility model to conduit detail 1 detects referring to Fig. 4, Fig. 5 The enlarging 1-1 ports of part 1 are caught between two measurement cephalic pars, and by being caught in the observation of state to it, setting is detected and led The enlarging 1-1 ports wall thickness of tube components 1 is H', and two measurement heads can be caught in if being detected the enlarging 1-1 ports of conduit detail 1 Between end, represent that being detected the enlarging 1-1 ports wall thickness H' of conduit detail 1 is less than standard value, i.e. H'< H, therefore can then judge It is detected conduit detail 1 and is not inconsistent standardization requirement;Two surveys can not be caught in if being detected the enlarging 1-1 ports of conduit detail 1 Between measuring cephalic par, represent that being detected the enlarging 1-1 ports wall thickness H' of conduit detail 1 is more than standard value, i.e. H' >=H, therefore can be then Judge that being detected conduit detail 1 meets standard requirement.
