Description

Technical Field

[0001] The utility model relates to a precision detection technology, in particular to a parallelism and coaxiality detection device. Background Art

[0002] In precision hardware processing, it is often necessary to test the verticality and parallelism of right-angle U-shaped workpieces, which are mainly long right-angle U-shaped workpieces with structural holes at set positions on both ends. After bending, such workpieces are likely to have holes on both sides that are not corresponding in height, or the bottom plane is uneven, forming an inclined slope. Under normal circumstances, the parallelism of the bottom surface can be tested by a separate bottom plane parallelism detection tool, and then the coaxiality tool can be used to detect the coaxiality of the structural holes at the corresponding positions. Such a detection process requires the use of two detection tools, which not only makes the detection work more time-consuming, but also increases the complexity of the detection process, which is not helpful for improving detection accuracy and detection efficiency. Utility Model Content

[0003] The technical problem solved by the utility model is to provide a parallelism and coaxiality detection device, which can quickly and accurately detect the coaxiality and parallelism of a U-shaped right-angle workpiece with a hole.

[0021] The utility model:

[0022] 1: Tool body 2: Coaxiality detection column 3: Parallelism detection block

[0024] 41: Structural holes DETAILED DESCRIPTION

[0025] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.

[0026] The utility model is a parallelism and coaxiality detection device, in which the preferred embodiment is shown in FIG. Figure 1 and Figure 2 As shown, the parallelism and coaxiality detection device of the utility model comprises a tool body 1, a coaxiality detection column 2 and a parallelism detection block 3. In general, the length, width and height of the tool body 1, as well as the size specifications of the coaxiality detection column 2 and the parallelism detection block 3 are designed according to the specifications of the workpiece 4 to be detected.

[0027] The tooling body 1 is a rectangular box structure with an opening on the top, and at least two groups of coaxiality detection holes 5 with corresponding heights are respectively provided on its two side surfaces, and at least two groups of parallelism detection holes 6 are provided at a set distance at the bottom of the two side surfaces; preferably, the coaxiality detection holes 5 can be circular holes or other polygonal structural holes 41.

[0028] The cross-sectional profile size of the coaxiality detection column 2 is the same as that of the coaxiality detection hole 5, and is used to be inserted into the coaxiality detection hole 5; the cross-sectional profile size of the parallelism detection block 3 is the same as that of the parallelism detection hole 6, and is used to be inserted into the parallelism detection hole 6; the tooling body 1 is used to place a workpiece 4 with specifications and dimensions that match it, and the structural hole 41 of the workpiece 4 corresponds to the position of the coaxiality detection hole 5, and the bottom surface of the workpiece 4 is flush with the upper edge of the parallelism detection hole 6. Preferably, through the insertion test of the coaxiality detection column 2 and the parallelism detection block 3, the test results of whether the coaxiality and parallelism are qualified can be accurately obtained.

[0029] As described above, in the preferred embodiment of the parallelism and coaxiality detection device of the utility model, two groups of coaxiality detection holes 5 and parallelism detection holes 6 are respectively provided on the two sides of the tooling body 1, and two coaxiality detection columns 2 and parallelism detection blocks 3 are correspondingly configured to be inserted therein. Preferably, generally at least two groups of detection holes and detection columns can be provided for corresponding detection, so as to achieve more accurate detection results.

[0030] As described above, in the preferred embodiment of the parallelism and coaxiality detection device of the utility model, the coaxiality detection hole 5 is a tapered hole structure, the hole opening of which gradually shrinks from the outside to the inside, and the diameter of the hole opening on the inside is the same as the cross-sectional size of the coaxiality detection column 2. Preferably, the coaxiality detection hole 5 is designed as a shrinking hole with a larger outside and a smaller inside, so that the operator can insert the coaxiality detection column 2 more smoothly when inserting it, and it will not be difficult to align it completely due to the same size.

[0031] In the preferred embodiment of the parallelism and coaxiality detection device of the utility model as described above, the parallelism detection hole 6 is a tapered hole structure, the hole opening of which gradually shrinks from the outside to the inside, and the diameter of the hole opening on the inside is the same as the cross-sectional size of the parallelism detection column. Preferably, the parallelism detection hole 6 is designed to be a shrinking hole with a large outside and a small inside and a buffer bevel, so that the operator can insert the parallelism detection block 3 more smoothly, and it will not be difficult to align it completely due to the same size.

[0032] In the preferred embodiment of the parallelism and coaxiality detection device of the utility model as described above, the length of the coaxiality detection column 2 and the parallelism detection block 3 is greater than the width of the tool body 1. In this way, after the operator picks up the coaxiality detection column 2 and the parallelism detection block 3 and completes the insertion, it is convenient to pull out the coaxiality detection column 2 and the parallelism detection block 3.

[0033] In the preferred embodiment of the parallelism and coaxiality detection device of the utility model as described above, the parallelism detection block 3 is fixed on the bottom of the tooling body 1. In a preferred case, the parallelism detection block 3 can be directly fixed on the inner bottom surface of the tooling body 1, and then the workpiece 4 is directly placed on the upper surface of the parallelism detection block 3, and then observe whether the coaxiality detection column 2 can be correspondingly inserted into the corresponding structural hole 41, so as to determine whether there is a parallelism problem or a coaxiality problem.

[0034] In the preferred embodiment of the parallelism and coaxiality detection device of the utility model as described above, the distance between the coaxiality detection hole 5 on the side of the tool body 1 and the top of the side is smaller than the distance between the structural hole 41 on the side of the workpiece 4 and the top of the side of the workpiece 4. Thus, after the coaxiality detection columns 2 are inserted into the coaxiality detection holes 5, the operator can observe whether the top edge of the workpiece 4 is parallel to the top edge of the tool body 1, so as to further determine whether there is a parallelism problem.

[0035] The parallelism and coaxiality detection device of the utility model integrates a coaxiality detection column 2 for coaxiality detection and a parallelism detection block 3 for parallelism detection into the same tooling body 1, and places a workpiece 4 as a whole into the tooling body 1 with pre-designed matching dimensions, and then inserts the coaxiality detection column 2 and the parallelism detection block 3 to perform coaxiality and parallelism detection. The same tooling can complete the two detections, and the two detections are integrated into the same procedure to complete, which reduces the detection difficulty of such workpieces 4, reduces the time consumed for such detection, and greatly improves the detection efficiency of the coaxiality and parallelism of such workpieces 4.

[0036] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any person skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
