Abstract
The utility model is a kind of indenture measuring instrument, comprises the indicating gauge with sounding rod and bearing, and the table body of indicating gauge is fixed in the upper end of bearing; The midline position of bearing is provided with the through hole of a through bearing upper/lower terminal, and the sounding rod of indicating gauge is plugged in this through hole, and the measurement point of sounding rod stretches out from the lower end of through hole; The lower end of bearing is a cross section is the prism of isosceles triangle, and the summit of this isosceles triangle is downward, and the rib residing for isosceles triangle summit is positioned at the extreme lower position of bearing; Measure point and exceed the rib being positioned at bearing extreme lower position, and the axis of sounding rod intersects vertically with the rib being positioned at bearing extreme lower position.Due to the simple compact of the utility model structure, so can measure body at any time.In addition, staff obtains by indicating gauge the depth value that institute's location puts indenture intuitively, and then passes judgment on the quality condition of tube surfaces, ensures the quality of production of product.
Description
Technical field
The utility model belongs to a kind of survey instrument, is specially a kind of indenture measuring instrument for measuring tube outside surface.
Background technology
At present, qualified petroleum pipeline body is required be: petroleum pipeline body does not allow to exist the defect that the degree of depth exceedes regulation wall thickness 12.5%; Finished product box cupling must not have macroscopic folding, crack and crackle; If be with fluted, similar shortcoming such as round bottom cutter trace, sharp trace etc., its degree of depth should more than 0.89mm.And existing detection means adopts ultrasound wave or magnetic crack detector to detect usually, although these equipment can check above defect, but limit by processing environment, generally only be applied to finished product factory inspection or arrival commodity inspection, and the on-line checkingi of production run can not be met, and then cannot Instructing manufacture timely, ensure the quality of production.
Utility model content
In view of this, the purpose of this utility model is to propose a kind of indenture measuring instrument, can directly measure the outside surface of body, and can reflect the depth value of indenture intuitively.
The utility model solves the technical scheme that its technical matters adopts: a kind of indenture measuring instrument, comprises the indicating gauge with sounding rod and bearing, it is characterized in that, the table body of indicating gauge is fixed in the upper end of described bearing; The midline position of bearing is provided with the through hole of a through bearing upper/lower terminal, and the sounding rod of described indicating gauge is plugged in this through hole, and the measurement point of sounding rod stretches out from the lower end of through hole; The lower end of bearing is a cross section is the prism of isosceles triangle, and the summit of this isosceles triangle is downward, and the rib residing for isosceles triangle summit is positioned at the extreme lower position of bearing; Described measurement point exceeds the rib being positioned at bearing extreme lower position, and the axis of sounding rod intersects vertically with the rib being positioned at bearing extreme lower position.
Further, the upper end of described bearing is the groove of an arc, the table body contour of this groove and described indicating gauge is suitable, and the two ends of groove are provided with solid table screw, and the table body of described indicating gauge is embedded in this groove and is also fixedly connected with the upper end of bearing by admittedly showing screw.
Further, the both sides indent of described bearing forms kidney-shaped.
Further, the prism cross section of described bearing lower end is equilateral triangle.
Further, described indicating gauge is dial gauge or clock gauge.
The beneficial effects of the utility model are, due to the simple compact of structure, so can measure body at any time.In addition owing to being provided with indicating gauge, staff can obtain the depth value that institute's location puts indenture intuitively, and then passes judgment on the quality condition of tube surfaces.The both sides of bearing being set to kidney-shaped is grip for the ease of staff.
From the above, the utility model is that the control of the body quality of production provides great convenience, there is the advantages such as measurement is convenient, measurement sensistivity is high, measuring accuracy is accurate, reproducible, not only be applied to finished product factory inspection or the commodity inspections such as petroleum pipeline body, box cupling, and on-line checkingi is realized in petroleum pipeline body, box cupling process, substantially increase the quality of production and processing efficiency and product.
Accompanying drawing explanation
Fig. 1 is Facad structure schematic diagram of the present utility model.
Fig. 2 is Fig. 1 left view.
In figure: 1. indicating gauge, 2. bearing, 3. sounding rod, 4. measure point, 5. admittedly show screw, 6. prism.
Embodiment
In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of indenture measuring instrument, comprises the indicating gauge 1 with sounding rod 3 and bearing 2.Wherein, the table body of indicating gauge 1 is fixed in the upper end of bearing 2.The midline position of bearing 2 is provided with the through hole of through bearing 2 upper/lower terminal.The sounding rod 3 of indicating gauge 1 is plugged in this through hole.The measurement point 4 of sounding rod 3 stretches out from the lower end of through hole.The prism 6 of to be cross sections be in the lower end of bearing 2 isosceles triangle also can be a cross section is the prism 6 of equilateral triangle.The summit of this isosceles triangle is downward, and the rib residing for isosceles triangle summit is positioned at the extreme lower position of bearing 2.It should be noted that, the measurement point 4 of sounding rod 3 exceeds the rib being positioned at bearing 2 extreme lower position, and the axis of sounding rod 3 is always with the rib being positioned at bearing 2 extreme lower position the state intersected vertically.Indicating gauge 1 can adopt dial gauge or clock gauge.
In order to indicating gauge 1 being firmly connected with bearing 2, the upper end of bearing 2 can be set to the groove of an arc, the table body contour of this groove and indicating gauge 1 is suitable.Solid table screw 5 is provided with at the two ends of groove.During installation, only the table body of indicating gauge 1 need be embedded in this groove and also lock by admittedly showing screw 5, indicating gauge 1 just firmly can be connected with the upper end of bearing 2.
In order to make operating personnel convenient to gripping of the present utility model, bearing 2 can be set to the kidney-shaped structure of both sides indent.
When the indenture of the utility model on measuring tube outside surface or crackle even depth, first by instrument horizontal positioned, indicating gauge 1 is returned to zero; Again this instrument vertical is placed on body, specifically the rib and body that are positioned at bearing 2 extreme lower position is touched, make measurement point 4 insert in indenture or crackle; Finally read the numerical value on indicating gauge 1, this numerical value is just the degree of depth of indenture or crackle.
The utility model measures convenient and swift and precision is high, not by the impact of processing environment, substantially increases the crudy of production efficiency and product.
