when the pipe fitting detection is finished, the second motor 6 is started to drive the maintaining rod 3 to deflect to one side, the maintaining rod 3 is moved away from the upper side of the detection tank 5, then the electric roller 24 is started to enable one end, close to the sequencing box 1, of the maintaining rod 3 to rotate downwards and incline, the pipe fitting slides outwards under the action of gravity, and the pipe fitting can slide outwards rapidly due to the fact that the blocking of the electric wheel 13 is omitted, and therefore the effect of taking out the detected pipe fitting rapidly is achieved.
As shown in fig. 1 to 7, the end of the cantilever 11 is fixedly connected with a motor six, the output end of the motor six is fixedly connected with a clamping arm 23, the clamping arm 23 is in a curved shape, a groove matched with the clamping arm 23 is formed in the top of the maintaining rod 3, and when the maintaining rod 3 returns to the upper side of the detection tank 5 in operation, in order to ensure stable and fixedly connection of the end, the clamping arm 23 is driven to rotate by the motor six and clamped into the groove in the top of the maintaining rod 3, so that the position of the maintaining rod 3 can be fixed, and errors generated in moving and returning are reduced.

during operation, the push-out mode is used for pushing out the pipe fitting from the sequencing box 1, the electric telescopic rod II 9 and the pipe fitting are required to be accurately aligned, an operation error is easy to occur, through the arrangement of the inner top sleeve 25, after the inner top sleeve 25 at the end part of the electric telescopic rod II 9 enters the pipe fitting, the diameter of the inner top sleeve 25 is smaller than the inner diameter of the pipe fitting, the air pump is used for filling air into the expansion bag, the expansion bag is expanded, and then the electric telescopic rod II 9 is determined to push out the pipe fitting.
During operation, through the arrangement of the friction wheel 16 and the electric wheel 13, the end part of a pipe fitting to be detected is placed in a gap between the electric wheel 13 and the friction wheel 16, at the moment, the electric wheel 13 and the friction wheel 16 are vertically arranged with the pipe fitting, the electric motor IV 19 and the electric motor V20 drive the electric wheel 13 and the friction wheel 16 to turn, so that the electric wheel 13 and the friction wheel 16 are no longer vertical to the pipe fitting but have a certain angle, at the moment, the electric wheel 13 is started to rotate, as the electric wheel 13 and the friction wheel 16 clamp the edge of the pipe fitting, the pipe fitting can rotate under the rotation of the electric wheel 13 and continuously move towards the other end of the maintaining rod 3 in the rotation process, and at the moment, the end part of the maintaining rod 3 is inserted into the pipe fitting, so as to assist the horizontal stabilization of the pipe fitting, until the pipe fitting is sleeved on the maintaining rod 3 completely, the friction wheel 1 passively rotates, the rotation number of the electric wheel 13 is counted, meanwhile, the turning angle of the electric wheel 13 is recorded, the length of the pipe fitting can be obtained through calculation, and at the same time, the thickness of the pipe fitting can be detected through the arrangement of the detecting assembly in the detection process, and the thickness of the pipe fitting is the detection assembly, and the pipe fitting can be detected, and the whole detection precision can be guaranteed in the detection process;
by horizontally placing the pipe fittings to be detected into the sequencing box 1, the space above the sequencing box 1 can be parallel to the other multilayer pipe fittings, the pipe fittings can move to the bottom of the sequencing box 1 under the action of gravity, only one row of pipe fittings can fall to the position of the pipe outlet hole 7 due to the limited width of the bottom of the sequencing box 1, and then the electric telescopic rod II 9 is started to push the pipe fittings outwards, so that the pipe fittings are pushed to the upper part of the supporting plate 2 and extruded to the upper parts of the friction wheel 16 and the electric wheel 13, and the mechanical pipe fitting feeding effect is realized;
in the undetected state, the spring in the first spring telescopic rod 17 stretches the detecting telescopic rod 26, at this moment, the count of the counting roller is zero, after the stainless steel tube is inserted between the friction wheel 16 and the electric wheel 13, the electric wheel 13 cannot move, so the friction wheel 16 is pushed upwards, the detecting telescopic rod 26 is shortened, the counting roller is shortened to rotate, the rotating quantity is digitized, the thickness of the pipe fitting can be obtained, meanwhile, in the continuous advancing process of the friction wheel 16, the count of the friction wheel 16 cannot be changed, if the count is changed, the thickness is different from the thickness of other positions, the position with different thickness of the pipe fitting can be estimated approximately by recording the walking path of the electric wheel 13 at this moment, and therefore the effect of detecting the thickness of the pipe fitting is accurately realized;
the friction wheel 16 is structurally arranged, so that the central position area of the friction wheel 16 protrudes, when a pipe fitting extrudes the outer side of the friction wheel 16, the friction wheel 16 can be smoothly jacked, and after jacking, only the protruding position at the center of the friction wheel 16 presses the inner wall of a stainless steel pipe fitting, thus the thickness of the friction wheel 16 can be ignored when detection starts, the error in the detection process is reduced, the top of the maintaining rod 3 is always attached to the inner wall of the pipe fitting after detection in the process of detecting the pipe fitting, and stable translation of the pipe fitting is ensured;
since the friction wheel 16 has larger diameter and some small concave positions, and is easy to ignore, by arranging two detection wheels 12 with smaller diameters, the detection wheels 12 are far smaller than the electric wheel 13, so that when the friction wheel passes through the small-area concave, the detection wheels 12 can sink into the pipe, the second spring telescopic rod 21 can be stretched when the friction wheel is sunk into the pipe, thus detecting the thickness change of the friction wheel, the fifth motor 20 is used for changing the direction of the detection wheels 12, and the angles of the detection wheels 12 and the electric wheel 13 relative to the pipe are the same;
in order to ensure that the pipe fitting keeps stable during moving, when the pipe fitting is ejected from the sequencing box 1, the pipe fitting passes through the two supporting sleeves 10 firstly, after the end part of the pipe fitting is connected with the maintaining rod 3, the front end and the rear end of the pipe fitting are provided with supporting points, so that the stability of the pipe fitting during detection is ensured, and the rotating ball is used for reducing the friction force between the pipe fitting and the supporting sleeves 10 during moving;
when the pipe fitting is completely separated from the sequencing box 1, the motor I4 is started to drive the whole supporting plate 2 to rotate, so that the pipe fitting rotates to be parallel to the electric telescopic rod I8, then the electric telescopic rod I8 is started to extend, the electric telescopic rod I8 is extruded and attached to the butt joint groove, and as the front end of the maintaining rod 3 is in a suspended state, the maintaining rod 3 is kept stable through extrusion support of the electric telescopic rod I8 in order to ensure that the maintaining rod 3 is stable and does not swing, so that the stable parallel detection process of the pipe fitting is ensured;
when the pipe fitting detection is finished, the second motor 6 is started to drive the maintaining rod 3 to shift to one side, the maintaining rod 3 is moved away from the upper part of the detection tank 5, then the electric roller 24 is started to enable one end of the maintaining rod 3 close to the sequencing box 1 to rotate downwards and incline, the pipe fitting slides outwards under the action of gravity, and the pipe fitting slides outwards rapidly due to the fact that the blocking of the electric wheel 13 is omitted, so that the effect of rapidly taking out the detected pipe fitting is achieved;
when the maintaining rod 3 returns to the upper part of the detection tank 5, in order to ensure the stable and firm connection of the end part, the clamping arm 23 is driven to rotate by the motor six and clamped into a groove at the top of the maintaining rod 3, so that the position of the maintaining rod 3 can be fixed, and errors generated during moving and returning are reduced;
the push-out mode is used for pushing out the pipe fitting from the sequencing box 1, the electric telescopic rod II 9 and the pipe fitting are required to be accurately aligned, an operation error is easy to occur, through the arrangement of the inner top sleeve 25, after the inner top sleeve 25 at the end part of the electric telescopic rod II 9 enters the pipe fitting, the diameter of the inner top sleeve 25 is smaller than the inner diameter of the pipe fitting, the air pump is used for filling air into the expansion bag, the expansion bag is inflated, and then the electric telescopic rod II 9 is fixed to push out the pipe fitting.
