This utility model provides a kind of flange hole center distance check tool, its objective is to improve detection efficiency, mitigates workload.
To achieve these goals, the technical scheme that this utility model is taken is:
Flange hole center distance check tool of the present utility model, for the company of the circumference uniform distribution on the adpting flange end face to cast tube Hole pitch-row detection is connect, described cubing is provided with cubing body;Described inspection is specially square tube made by steel, in the same face of square tube Two detection inserts of upper setting are fixedly connected with described cubing body;Described detection insert is formed with described connecting hole and is slided Coordinate;The centre-to-centre spacing of two described detection inserts is equal to two connecting holes be distributed on circle diameter on described adpting flange Hole centre-to-centre spacing.
Described detection insert is stretched out the structure of the detection position outside described square tube and is cylinder and carries out by its axis Cut flat structure.
Described square tube is provided with the detection insert installing hole in the aperture less than described connecting hole, described detection insert One end be pressed into the detection insert installing hole.
Described detection insert is adopted with square tube and is welded to connect.
The reverse side of two described detection inserts is installed in described square tube, two detection inserts are still further installed, this two The centre-to-centre spacing of individual detection insert be equal to the mesopore heart of two adjacent connecting holes on circumference on described adpting flange away from.
This utility model adopts above-mentioned technical proposal, with advantages below:
1st, cubing is simple to operate, convenient, can accurately check workpiece, reduce measurement error, improves the work of detection Efficiency;
2nd, detection tool structure is simple, low cost of manufacture, and high recycling rate;
3rd, cubing high precision, effectively quick detection can go out flange hole centre-to-centre spacing whether there is skew and flange hole ovality.

Content shown in accompanying drawing and the labelling in figure are briefly described as follows:
Fig. 1 is working state schematic representation of the present utility model;
Fig. 2 is structural representation of the present utility model;
Structural representations of the Fig. 3 for the A-A section views in Fig. 2;
Schematic top plan views of the Fig. 4 for structure shown in Fig. 2.
It is labeled as in figure:
1st, cast tube, 2, cubing, 3, cubing body, 4, detection insert, 5, weld seam.
Specific embodiment
Below against accompanying drawing, by the description to embodiment, specific embodiment of the present utility model is made further in detail Thin explanation, with help those skilled in the art inventive concept of the present utility model, technical scheme are had it is more complete, accurately and Deep understanding.
Structure of the present utility model, is a kind of flange hole center distance check tool, for the company to cast tube 1 as shown in Figures 1 to 4 The connecting hole pitch-row detection of the circumference uniform distribution on acting flange end face, described cubing 2 are provided with cubing body 3.
In order to solve the problems, such as prior art and overcome its defect, realize improving detection efficiency, mitigate workload Goal of the invention, the technical scheme that this utility model is taken is:
As shown in Figures 1 to 4, flange hole center distance check tool of the present utility model, described cubing body 3 are made by steel Square tube, is arranged two detection inserts 4 on the same face of square tube and is fixedly connected with described cubing body 3;Described detection insert 4 Formed with described connecting hole and be slidably matched;The centre-to-centre spacing of two described detection inserts 4 is equal to circle on described adpting flange The hole centre-to-centre spacing of two connecting holes that week is diametrically distributed.
Two detection inserts 4 sizes be respectively:The maximum limit of size of flange connecting hole, the minimum limit of size.So, May determine that whether the ovality of connecting hole is qualified.
Using square tube as the main body of cubing, the weight of cubing is significantly reduced, facilitate which to use and operate.Using above-mentioned Appliance special for detecting, can draw centre-to-centre spacing whether in the margin of tolerance by once determining, improve detection efficiency, mitigate workload;Energy Whether qualified the centre-to-centre spacing of enough intuitive judgment products asks, reduces because of error caused by manual measurement.
Described detection insert 4 is stretched out the structure of the detection position outside described square tube and is cylinder and carries out by its axis Cut flat structure.
Using flat structure is cut, the contact area of detection insert 4 and the flange connecting hole of cast tube 1 is reduced, and reduction was detected Abrasion in journey.Meanwhile, also mitigate the weight of cubing.
Described square tube is provided with the detection insert installing hole in the aperture less than described connecting hole, described detection insert 4 one end is pressed into the detection insert installing hole.
Detection insert 4 defines a step, and it is more accurate and stable which axially connects.
Described detection insert 4 is adopted with square tube and is welded to connect.Welding forms weld seam 5, makes main body square tube and the inspection of cubing Survey the secure and reliable connection of insert 4.
The reverse side of two described detection inserts 4 is installed in described square tube, two detection inserts 4 are still further installed, this The centre-to-centre spacing of two detection inserts 4 be equal to the mesopore heart of two adjacent connecting holes on circumference on described adpting flange away from.Together The principle of sample, two detection inserts 4 sizes be respectively:The maximum limit of size of flange connecting hole, the minimum limit of size.
In a cubing main body, you can to realize the measurement of the maximum distance between centers to flange connecting hole, can also be to phase The measurement of adjacent connecting hole centre-to-centre spacing, the versatility and practicality of cubing are greatly improved.
The advantage of technical solutions of the utility model is:
1st, detect simple to operate, convenient, workpiece can accurately be checked, measurement error is reduced, the work of detection is improve Efficiency;
2nd, detection tool structure is simple, low cost of manufacture, and recycling rate of waterused is good, high precision;
3rd, effectively quick detection can go out flange hole centre-to-centre spacing whether there is skew and flange hole ovality;
4th, can not only be to the measurement of the maximum distance between centers of flange connecting hole, can also be to the survey of adjacent connecting hole centre-to-centre spacing Amount, improves its versatility and practicality.
The using method of cubing of the present utility model is:
1st, cubing positioning insert 4 is alignd insertion flange hole, whether detection flange centre-to-centre spacing and aperture are qualified;
2nd, positioning insert 4 smoothly can be coordinated with flange hole, then flange hole centre-to-centre spacing is qualified, it is impossible to smoothly coordinate, then judge Centre-to-centre spacing is unqualified;
3rd, cardinal principle is to detect flange hole ovality, the centre-to-centre spacing detection flange hole of insert by 4 external diameter of positioning insert Centre-to-centre spacing.
This utility model is exemplarily described above in conjunction with accompanying drawing, it is clear that this utility model is implemented not to be received The restriction of aforesaid way, as long as employing changing for the various unsubstantialities that method design of the present utility model and technical scheme are carried out Enter, or it is not improved by it is of the present utility model design and technical scheme directly apply to other occasions, in this utility model Protection domain within.
