[0003] At present, in order to determine whether the bending radius of large square tube-shaped bent parts is qualified, precision equipment such as three-dimensional detection is used, which is costly and inefficient, and is not suitable for online detection and determination in production. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model provides a square tube bending profiling gauge, which has the advantages of low cost and high effect, and solves the existing problems.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a square tube bending profiling gauge, comprising a profiling gauge body, a first arc-shaped bar and a second arc-shaped bar are arranged inside the profiling gauge body, the second arc-shaped bar is located on the opposite side of the first arc-shaped bar, threaded holes are opened inside both sides of the profiling gauge body, the threaded holes are threadedly connected with threaded rods, the number of the threaded rods is two, one end of one of the threaded rods is installed together with the first arc-shaped bar through a bearing, and one end of the other threaded rod is installed together with the second arc-shaped bar through a bearing, and the other ends of the two threaded rods are welded with handles.
[0006] Preferably, a workbench is provided at the bottom of the profiling gauge body, and the workbench is square in shape as a whole.
[0007] Preferably, the bottom of the workbench is fixedly connected with supporting legs, and the number of the supporting legs is four.
[0008] Preferably, a collection box is provided directly below the workbench, and a partition is fixedly connected to the interior of the collection box.
[0009] Preferably, a pull ring is welded on the front side of the collection box, and a pull groove is opened inside the partition.
[0010] Preferably, the bottom of the collection box is rotatably connected with self-locking universal wheels, and the number of the self-locking universal wheels is four.
[0011] In summary, the present invention has at least one of the following beneficial effects:
[0012] 1. The square tube bending profiling gauge can effectively determine the eligibility of the bending radius and the inner and outer arc contours of the bent tube through the detection components set up. It is low-cost, suitable for online detection of mass production, and has high detection efficiency. When the bent part passes smoothly through the cavity opened inside the profiling gauge body, the product is judged to be qualified, otherwise it is judged to be unqualified. At the same time, the second arc bar is used to check the fit of the outer arc contour of the bent part, and the first arc bar is used to check the fit of the inner arc contour of the bent part. If the contour fit is good, the product is judged to be qualified; if there is a local contour fit that is poor and exceeds the contour requirement, it is judged to be unqualified. When it is necessary to detect bent parts with different inner diameters in the later stage, the two threaded rods can be turned by the handle so that the two threaded rods drive the first arc bar and the second arc bar to perform relative reciprocating motion, thereby changing the size of the cavity inside the profiling gauge body, which is convenient for application to bent parts with different inner diameters.
[0013] 2. The square tube bending profiling gauge facilitates the storage and transportation of the tested bent parts through the rotating components, preventing the tested bent parts from piling up on the workbench and hindering the operator's operation. When in use, the partition divides the collection box into two parts, and the internal space of the collection box is divided into two parts. The qualified bent parts are placed in one space, and the unqualified bent parts are placed in the other space. Then, the bent parts after testing are transported using the pull ring and the self-locking universal wheel configuration, which improves the convenience of the operator.
