Description

Technical Field

[0001] The invention relates to the technical field of stainless steel pipe detection, in particular to an automatic continuous detection device for the outer diameter of a stainless steel pipe. Background Art

[0002] After the production of stainless steel pipe outer diameter tube is completed, it is necessary to test the hardness of stainless steel pipe outer diameter tube. Generally, Brinell, Rockwell and Vickers hardness indicators are used to measure the hardness of stainless steel pipe outer diameter tube. At the same time, it is also necessary to measure the coaxiality of stainless steel pipe outer diameter tube. Go and no-go gauge is a kind of gauge. As a measurement standard, it is used for the inspection of large quantities of products. Go and no-go gauge is also usually used for outer diameter detection in stainless steel pipe production. The existing outer diameter detection device can basically meet the use requirements of stainless steel pipe production, but there are still some shortcomings that need to be improved. In the prior art, an integrated go and no-go gauge is usually used for detection, but obviously the integrated structure is unusable as a whole when any end is worn, and the cost is relatively high. When testing the split go and no-go gauge, it is necessary to operate the go gauge and the no-go gauge on the detection structure respectively.

[0003] For example, the Chinese patent with publication number CN117968493A effectively solves the above problem, but the go / no-go gauge is distinguished manually by naked eyes. After working for a long time, the staff is prone to visual fatigue, which leads to inaccurate detection results. Summary of the invention

[0004] The purpose of the present invention is to provide an automatic continuous detection device for the outer diameter of a stainless steel pipe, so as to solve the problem that workers are prone to visual fatigue after long-term work, which leads to inaccurate detection results.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an automatic continuous detection device for the outer diameter of a stainless steel pipe, comprising a standard pipe fitting and a measuring pipe fitting, a pipe fitting measuring assembly and a standard fitting installation assembly; the pipe fitting measuring assembly and the standard fitting installation assembly are combined to form a whole, and the standard pipe fitting is installed on one end of the pipe fitting measuring assembly through the standard fitting installation assembly. At this time, a cylindrical space is formed inside the pipe fitting measuring assembly, and the pipe fitting measuring assembly is sleeved on the outside of the measuring pipe fitting, and the measuring pipe fitting is inserted into the cylindrical space formed inside the pipe fitting measuring assembly. When the outer wall of the measuring pipe fitting is tightly fitted with the pipe fitting measuring assembly, the pipe fitting meets the standard, and the measurement is completed.

[0006] Preferably, the pipe fitting measuring assembly includes a position adjustment disk and a measuring piece, the measuring piece is composed of a plurality of contact tubes A, special-shaped tubes, and contact tubes B, each contact tube A includes two special-shaped tubes at both ends, the contact tube A is welded and fixed to the special-shaped tube, one end of each special-shaped tube includes a contact tube B, one end of the contact tube B is welded and fixed to the special-shaped tube, the number of position adjustment disks is two, each position adjustment disk is provided with a plurality of guide rails, the two special-shaped tubes at both ends of the position adjustment disk are respectively embedded in the guide rails on the two position adjustment disks and are slidably connected to the position adjustment disk, and the special-shaped tubes are slidably adjustable along the track of the guide rails The distance between the two contact tubes A is adjusted to form cylindrical spaces of different sizes, thereby realizing the outer diameter detection of stainless steel tubes of different diameters. Multiple gaskets A are welded and fixed on the front and back of the position adjustment disk, and springs are symmetrically welded and fixed at both ends of one side of each gasket A. An integrally fixed gasket B is arranged in the center of each special-shaped tube, and one end of the spring away from the gasket A is welded and fixed to the gasket B. The gasket B can be pushed by multiple springs, so that the gasket B pushes the special-shaped tube to slide inside the guide rail, thereby adjusting the distance between the two contact tubes A, and then detecting stainless steel tubes of different diameters.

[0007] Preferably, grooves are provided on both sides of each guide rail, and there are integrally fixed sliders on both sides of each special-shaped tube. The sliders are embedded in the grooves and are slidably connected to the position adjustment disk. When the special-shaped tube slides inside the guide rails, the sliders slide synchronously inside the grooves. The sliders are rectangular and have high stability when sliding, so that the special-shaped tube will not rotate or shake when sliding, thereby maintaining the stability of the special-shaped tube when sliding.

[0008] Preferably, multiple guide rails are opened symmetrically on the left and right, and there is an angle between every two adjacent guide rails. The angle between the two guide rails at the top and the bottom is larger. When the special-shaped tubes at the top and the bottom of the position adjustment disk slide in the guide rails, the angle between the two special-shaped tubes is enlarged, and the springs on the special-shaped tubes are squeezed and contracted, thereby enlarging the distance between the two special-shaped tubes. When the distance between the two special-shaped tubes is enlarged, the measuring tube to be tested can be inserted from the top, and the special-shaped tube is loosened so that the spring on the special-shaped tube rebounds and pushes the special-shaped tube to reset, and then the measuring tube is wrapped by multiple contact tubes A to measure the diameter. After the test is completed, the contact tube B close to the bottom is pushed, so that the spring on the bottom special-shaped tube is squeezed, the angle of the bottom special-shaped tube is enlarged, and the distance between the bottom special-shaped tubes is enlarged.

When multiple contact tubes B wrap the standard pipe fitting, multiple rubber tubes are enclosed to form a cylindrical tube. At this time, the diameter of the cylindrical tube is equal to the diameter of the standard pipe fitting. The outside of the measuring pipe fitting is fitted with multiple rubber tubes. If the outside of the measuring pipe fitting is equal to the diameter of the cylindrical tube, and the standard pipe fitting is tightly fitted with the contact tube B on the outside, the diameter of the measuring pipe fitting being tested is equal to the diameter of the standard pipe fitting, and the outer diameter of the measuring pipe fitting is qualified. If the diameter of the measuring pipe fitting is smaller than the diameter of the cylindrical tube, the diameter of the measuring pipe fitting is too small. If the diameter of the measuring pipe fitting is wrapped by the cylindrical tube formed by the rubber tube, and the standard pipe fitting is separated from the contact tube B, the outer diameter of the measuring pipe fitting is too large.

[0010] Preferably, the standard parts installation assembly includes a connecting piece, a conical barrel, a mounting frame, a threaded rod, a limit frame, and a pipe sleeve; the connecting piece is embedded in the middle of the position adjustment disk, and there are two mounting frames. One end of the two mounting frames is welded and fixed to the connecting piece, and a plurality of limit blocks are welded and fixed to one side of the position adjustment disk. A spacing is provided between each two limit blocks, and the two sides of the mounting frame are respectively fitted with the two limit blocks. Screws are installed on the mounting frame for limit fixing. The connecting piece and the position adjustment disk are a split structure. During installation, the position is limited by a plurality of limit blocks. Limiting in this way prevents the positions of the components from being offset under long-term use, and no position calibration is required.

[0011] Preferably, the cone barrel is integrally fixed to one end of the connecting piece, one end of the pipe sleeve is welded and fixed to one end of the cone barrel, the threaded rod is embedded in the interior of the pipe sleeve and rotatably connected to the pipe sleeve, the limit frame is sleeved on the outside of the threaded rod and is threadedly connected to the threaded rod, and one end of the standard pipe fitting is sleeved on the outside of the cone barrel.

After the standard pipe fitting is sleeved on the outside of the cone barrel, the limit frame is sleeved on the outside of the threaded rod, and the threaded rod is rotated to make the limit frame slide on the threaded rod, so that the limit frame fits with one end of the standard pipe fitting, and the standard pipe fitting can be clamped by continuous rotation to fix the position.

[0012] Preferably, the cavity formed by the multiple contact tubes B is cylindrical, and the outer side of the standard pipe fitting is fitted with the multiple contact tubes B. When the multiple contact tubes B wrap the standard pipe fitting, the multiple rubber tubes are enclosed to form a cylindrical tube. At this time, the diameter of the cylindrical tube is equal to the diameter of the standard pipe fitting, forming a measurement space.

[0013] Preferably, a connecting frame is installed on the inner side of the connecting piece, and the connecting frame is made of plastic. The connecting frame is fixed to the inner side of the connecting piece by hot melting.

A wire is connected between each metal frame and the copper wire on the outside of a contact tube A, and a test light is installed at one end of each metal frame.

If the outer wall of the measuring pipe fits tightly with the pipe measuring component, the pipe meets the standard, and the measurement is completed. A wire is connected between each metal frame and a copper wire contacting the outside of tube A, and a test light is installed at one end of each metal frame. The two ends of the measuring pipe fit with the metal frame to form a circuit. If all the copper wires on the outside of the measuring pipe touch the outer wall of the measuring pipe, a loop is formed at this time, so that the test lights on all the metal frames are lit. If some of the test lights are not lit, it means that the diameter of the measuring pipe does not meet the standard.

The measuring piece 300 is composed of a plurality of contact tubes A301, special-shaped tubes 303, and contact tubes B306. The two ends of each contact tube A301 include two special-shaped tubes 303. The contact tube A301 is welded and fixed to the special-shaped tube 303. One end of each special-shaped tube 303 includes a contact tube B306. One end of the contact tube B306 is welded and fixed to the special-shaped tube 303. There are two position adjustment disks 100.

By rotating the threaded rod 203, the limit frame 204 slides on the threaded rod 203, and the limit frame 204 fits with one end of the standard pipe fitting 400. Continuous rotation can clamp the standard pipe fitting 400 to fix the position. At this time.
