Abstract
Tubing, Surface of Rod Bar depth of defect detection means disclosed in the utility model, including support frame, are provided with mounting hole on support frame, amesdial is fixed with mounting hole, and the front end that amesdial has contact, contact is connected with needle point contact pilotage.Be arranged on amesdial on the support frame with mounting hole by tubing of the present utility model, Surface of Rod Bar depth of defect detection means, the height of amesdial can be presetting, and locked using fastening bolt, former amesdial contact is substituted with needle point contact pilotage, the contact area for making measurement contact point is far smaller than the contact area of former amesdial contact, so as on the basis of quick detection, also greatly improve the accuracy of detection of surface defect depth.
Description
Technical field
The utility model belongs to testing equipment technical field, and in particular to a kind of tubing, the detection of Surface of Rod Bar depth of defect
Device.
Background technology
In the tubing such as metal material, the production of bar, the depth of defect detection work on its surface is one and is relatively difficult to
Tubing, the bar of the work realized at the scene, particularly path in itself surface defect very it is small be difficult measurement.The applying date is
On October 26th, 2010, Application No. 201020588917.5, authorized announcement date were for July 6, Authorization Notice No. in 2011
CN201892507U, the Chinese patent of entitled Surface Flaw depth measurement device disclose a kind of measurement apparatus, its by
One industrial microscope and an amesdial are combined, and a linkage detection plate, linkage are set in the objection lens portion of industrial microscope
Detection plate is moved with object lens, and amesdial gauge stand is connected with industrial microscope body by connecting rod, and gauge outfit compresses detection plate.Detection
During workpiece, adjusting microscopical focusing bracelet makes micro objective be focused on examined workpiece surface, records amesdial reading.Adjustment
Microscopical focusing bracelet makes micro objective be focused on for second in defect bottom, amesdial reading is recorded, thousand when focusing on twice
The reading difference of table is divided to be depth of defect.This detection means disclosed in the patent is very suitable for detecting flat workpiece surface
Depth of defect, is not particularly suited for detection tubing, the depth of defect of Surface of Rod Bar.
Utility model content
The purpose of this utility model is to provide a kind of tubing, Surface of Rod Bar depth of defect detection means, is solved existing
Deep defects structure of the detecting device it is complicated and be not suitable for tubing, the problem of Surface of Rod Bar depth of defect detection.
The technical scheme that the utility model is used is：Tubing, Surface of Rod Bar depth of defect detection means, including support
Frame, is provided with mounting hole on support frame, amesdial is fixed with mounting hole, and the front end that amesdial has contact, contact is connected with
Needle point contact pilotage.
The characteristics of the utility model, also resides in,
Support frame is by support panel and is arranged at multiple legs of support panel lower surface and constitutes, and is set on support panel
There is the mounting hole for running through up and down, amesdial is fixed in mounting hole by the fastening bolt through support panel.
The beneficial effects of the utility model are：Tubing of the present utility model, Surface of Rod Bar depth of defect detection means are solved
Existing deep defects structure of the detecting device is complicated and is not suitable for tubing, the problem of Surface of Rod Bar depth of defect detection.This
The tubing of utility model, Surface of Rod Bar depth of defect structure of the detecting device are simple, only need to twice detect and calculate amesdial most
The difference of big value and minimum value is depth of defect, is highly suitable for Site Detection.
Brief description of the drawings
Fig. 1 is tubing of the present utility model, the structural representation of Surface of Rod Bar depth of defect detection means.
In figure, 1. amesdial, 2. support panel, 3. leg, 4. fastening bolt, 5. contact, 6. needle point contact pilotage.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
Tubing, the structure of Surface of Rod Bar depth of defect detection means that the utility model is provided are as shown in figure 1, including by propping up
Support panel 2 and be arranged at the support frame that four legs 3 of the lower surface of support panel 2 are constituted, and four bottom surfaces of leg are same
On one horizontal plane, the mounting hole for running through up and down is provided with support panel 2, amesdial 1 is placed with mounting hole, amesdial 1
Then height can be fixed in mounting hole with presetting by the fastening bolt 4 through support panel 2, and amesdial 1 has contact 5,
The front end of contact 5 is connected with the front end of needle point contact pilotage 6, the diameter of the diameter much smaller than contact 5 of needle point contact pilotage 6, and needle point contact pilotage 6
Contact is much smaller than the front end of contact 5 with the contact area of measured object.
During measurement, tubing, bar are placed on horizontal platform and through four legs 3, tubing, bar is then fixed
Its defect is placed in topmost, then the needle point contact pilotage 6 of the utility model detection means is found in the inside micro-shifting of surface defect
The minimum value of amesdial 1, i.e., contact the bottom level for measuring surface defect with surface defect bosom；Again along tubing, bar
One section of slight distance of axially in parallel movement makes needle point contact pilotage 6 reach tubing, Surface of Rod Bar, records the reading of amesdial 1, that is, measure
Pipe, Surface of Rod Bar highly, the surface defect depth of the difference in height for measuring the twice as tubing, bar.
Amesdial is arranged on the branch with mounting hole by tubing of the present utility model, Surface of Rod Bar depth of defect detection means
On support, the height of amesdial can be presetting, and is locked using fastening bolt, and former amesdial contact is substituted with needle point contact pilotage, makes survey
The contact area for measuring contact point is far smaller than the contact area of former amesdial contact, also big so as on the basis of quick detection
The big accuracy of detection for improving surface defect depth.
