The integrated detection device for conveying, detecting and subsequently detecting whether the pipe fitting is qualified or not is used for processing the pipe fitting, so that the length measurement of the pipe fitting and the qualified production of the pipe fitting are realized. By feeding mechanism and guiding mechanism cooperation, guaranteed the detection order nature of measuring tube spare, every pipe fitting and the transmission process ability isochronism of pipe fitting, and then guaranteed that measuring mechanism detects time has the security.

The limiting baffle 2 is arranged for limiting one end of the pipe when measuring pipes with different lengths, so that two ends of the pipe can move to the inlet of the falling channel 7 as orderly as possible.
The limiting and fixing mechanism comprises a drop tube guiding limiting block 51, a door opening and closing baffle plate 30 and a region to be detected 44, wherein the region to be detected 44 is arranged among four directions of the ejection driving power plate 29, the ejection driving driven plate 52, the drop tube guiding limiting block 51 and the door opening and closing baffle plate 30. The pipe fitting to-be-detected area 44 is arranged between the fixed pipe falling guide limiting block 51 and the door opening and closing baffle 30, and the pipe fitting is clamped by the ejection driving power plate 29 and the ejection driving driven plate 52 to move to the to-be-detected area 44 for detecting the pipe fitting, so that the limitation of the upper and lower directions, the front and rear directions of the pipe fitting is realized. The drop tube guide stopper 51 not only plays a role in guiding the tube falling onto the baffle, but also plays a role in fixing the tube in the limit fixing mechanism.
The measuring mechanism includes a measuring thimble 39, a detecting cylinder 34, a buffer spring 42, a com displacement sensor 31, and a detecting reflecting surface 32. The measuring thimble 39 is moved forward by the shaft of the detecting cylinder 39 against the buffer spring 42 until the measuring thimble abuts against the end face of the detecting pipe fitting, and at this time, the distance between the com displacement sensor 31 and the detecting reflecting surface is read, so that the length of the detecting pipe fitting can be compared with the initial value.

The purpose of the profiled connecting plate 19 is to ensure a fixed distance between the ejector-drive power plate 29 and the ejector-drive follower plate 52.
At this time, the pipe to be tested passes through the ejector driving power plate 29 and the ejector driving driven plate 52, and the pipe falling guide limiting block 51 and the switch door baffle 30 limit the pipe in four directions. So that the pipe material is in a straight line with the measuring limiting thimble 20 and the measuring thimble 39.
The detection cylinder 34 then drives the measurement thimble 39 to act. The front end of the measuring thimble 39 is always contacted with the end face of the product to be measured by matching with the buffer spring 42.
Finally, the coms displacement sensor 31 detects the change of the compression degree of the buffer spring 42 caused by the change of the pipe length, and drives the change of the relative distance between the detection reflecting surface 32 and the coms displacement sensor 31 to judge the difference value of the product length. And further judging whether the pipe is a qualified product.
If the length of the pipe fitting is judged to be qualified by the PLC control system, the detection cylinder 34 drives the measurement thimble 39 to retract, the door opening and closing cylinder 16 drives the door opening and closing baffle 30 to open, and the qualified product falls into a qualified area. If the PLC control system judges that the pipe fitting length is unqualified, the sorting air cylinder 22 drives the sorting guide plate 27, then the detection air cylinder 34 drives the measuring thimble 39 to retract, and the door opening and closing air cylinder 16 drives the door opening and closing baffle plate 30 to open the door, so that the pipe fitting length is unqualified and falls into an unqualified area. Then the back door opening and closing cylinder 16 drives the door opening and closing baffle 30 to close, and the ejection cylinder 15 drives the ejection driving power plate 29 to be matched with the ejection driving driven plate 52 connected with the special-shaped connecting plate 19, and the ejection driving power plate 29 and the ejection driving driven plate 52 are restored to the original positions, namely, the positions of the pipe fittings where the pipe falling channels 49 drop are initially received by the ejection driving power plate 29 and the ejection driving driven plate 52.
And (5) periodically repeating the processes to finish the processes of measuring and sorting the pipe fittings and the like.
The measuring mechanism further comprises a fixed plate 35, an adjusting plate 36, a stop block 37, a measuring optical axis 33, a measuring bearing 38, a measuring thimble pressing plate 40 and a limiting plate 41; the two fixed plates 35 are connected through a measuring optical axis 33, a measuring bearing 38 is arranged at the joint of the measuring optical axis 33 and the fixed plates 35, an adjusting plate 36 is connected on the measuring optical axis 33, a detecting air cylinder 34 is arranged on one fixed plate 35 on the inner side of the two fixed plates 35, a comm displacement sensor 31 is arranged on one side of the other fixed plate 35, a detecting reflecting surface 32 is arranged at the same side position of the adjusting plate 36 corresponding to the same side where the comm displacement sensor 31 is arranged on the fixed plate 35, the detecting air cylinder 34 is connected with the adjusting plate through a buffer spring 42, and an output shaft of the detecting air cylinder 34 passes through the buffer spring 42 and the adjusting plate 36 and is connected with a stop block 37; the measuring optical axis 33 is connected to the limiting plate 41 through the fixing plate 35 to which the com displacement sensor 31 is connected, and the measuring thimble 39 is connected to the limiting plate 41 through the measuring thimble pressing plate 40. The same way is used for measuring the limiting thimble 20, and the limiting thimble pressing plate 21 is fixed on one side of the to-be-detected area 44, so that the position of the limiting thimble 20 is convenient to adjust when measuring pipe fittings with different lengths, and meanwhile, the limiting thimble 20 is ensured not to move when measuring the pipe fittings. The change in distance between the fixed plate 35 and the regulating plate 36 directly causes the change in distance between the coms displacement sensor 31 and the detection reflecting surface 32 provided on the same side therebetween, so that the coms displacement sensor 31 detects the change in displacement with the detection reflecting surface 32, and the coms displacement sensor 31 transmits the detected value to the PLC control system to determine whether the comparison is within the range of the pipe length set initially. The complete use principle of the measuring mechanism is as follows: the premise is that the pipe fitting with the length to be measured is already transmitted into the area to be measured 44, and between the measuring thimble 39 and the measuring limiting thimble 20, firstly, an output shaft connected with the detecting cylinder 34 arranged on the fixed plate 35 drives the stop block 37 to directly abut against the measuring thimble 39, so that the measuring thimble 39 starts to move, and the front end of the measuring thimble 39 is matched with the end face of the pipe fitting to be measured at any time; secondly, when the front end of the measuring thimble 39 is stressed, the limiting plate 41 drives the measuring optical axis 33 to move, and then, the measuring optical axis 33 also drives the detecting reflecting surface 32 arranged on the adjusting plate 36 to be close to the com displacement sensor 31, and the numerical value detected by the com displacement sensor 31 is transmitted to the PLC control system to judge whether the comparison is in the length range of the pipe fitting which is originally set; finally, the next operation of the sorting mechanism is controlled by the comparison result of the PLC control system. If the length of the pipe fitting is judged to be qualified by the PLC control system, the detection cylinder 34 drives the measurement thimble 39 to retract, the door opening and closing cylinder 16 drives the door opening and closing baffle 30 to open, and the qualified product falls into a qualified area. If the PLC control system judges that the pipe fitting length is unqualified, the sorting air cylinder 22 drives the sorting guide plate 27, then the detection air cylinder 34 drives the measuring thimble 39 to retract, and the door opening and closing air cylinder 16 drives the door opening and closing baffle plate 30 to open the door, so that the pipe fitting length is unqualified and falls into an unqualified area. Then the back door opening and closing cylinder 16 drives the door opening and closing baffle 30 to close, and the ejection cylinder 15 drives the ejection driving power plate 29 to be matched with the ejection driving driven plate 52 connected with the special-shaped connecting plate 19, and the ejection driving power plate 29 and the ejection driving driven plate 52 are restored to the original positions, namely, the positions of the pipe fittings where the pipe falling channels 49 drop are initially received by the ejection driving power plate 29 and the ejection driving driven plate 52. The stopper 37 serves to restrict the regulating plate 36 from falling off along the measurement optical axis 33.
The measuring mechanism is arranged on one side of the bottom surface of the bearing platform 1, the measuring limiting thimble 20 is arranged on the other side of the bottom surface of the bearing platform 1, the measuring limiting thimble 20 is opposite to the measuring thimble 39 at the front end of the measuring mechanism, and the moving direction of the measuring thimble 39 and the measuring limiting thimble 20 are on the same straight line. The measuring mechanism is arranged at a position opposite to one side of the area 44 to be detected, the measuring limiting thimble 20 is arranged at the other side of the area 44 to be detected, the purpose of the arrangement is to realize the integration of the measuring mechanism and the integral type detecting device for the length of the whole pipe fitting, and meanwhile, the clamping and measuring functions are realized in the directions of two ports of the measuring pipe fitting when the pipe fitting is measured, the guiding mechanism and the limiting fixing mechanism limit the pipe fitting to be detected in the area 44 to be detected in an omnibearing manner, and the measured length value of the pipe fitting is ensured to be quite accurate.
The area 44 of the tube to be inspected is disposed between the measurement limiting thimble 20 and the measurement thimble 39. After the pipe fitting to be measured is transferred to the area to be detected 44, the setting positions of the measuring thimble 39 and the measuring limiting thimble 20 determine the measuring speed of the pipe fitting, and furthermore, the setting positions of the measuring thimble 39 and the measuring limiting thimble 20 improve the running speed of the integral pipe fitting length detecting device.
The guide mechanism further comprises a drop tube guide plate 50, a parallel bearing 13, an optical axis 14 and an ejection driven cylinder 25, wherein the transmission path of the optical axis 14 is perpendicular to the movement path of a measuring thimble 39 of the measuring pipe fitting of the measuring mechanism, and the parallel bearing 13 is arranged on the optical axis 14. The parallel bearings 13 and the optical axis 14 are arranged to facilitate the horizontal transmission of the pipe fitting to the transmission channel of the region to be detected 44 after the pipe fitting falls to the pipe falling channel 49 from top to bottom, so as to prevent the uncertainty of the pipe fitting transmission process direction from affecting the detection data difference of the pipe fitting and even affecting the accuracy of the detection result of the pipe fitting; the function of the ejection driven cylinder 25 is to cooperate with the consistency of the running direction of the ejection cylinder 15 to ensure that the vibration of the equipment is reduced in the pipe transmission process clamped between the ejection driving power plate 29 and the ejection driving driven plate 52 when the pipe to be measured is transmitted. The drop tube guide plate 50 and the drop tube guide limiting block 51 realize limiting effect on the drop channel of the pipe fitting.

The design purpose of the measurement thimble 39 and the measurement limit thimble 20, which are the same in diameter of the end face contacting the pipe, is to make the stress of the measured pipe on the end face contacting the measurement thimble uniform, so as to prevent uneven stress of the measured pipe caused by different stress of the contact end face of the pipe, and further to cause bending in the middle of the pipe or abrasion of the end face, and influence the numerical accuracy of the final pipe detection. The diameter size should be between the external diameter and the internal diameter of tubular product the numerical value, measure thimble 39 diameter size can not be less than the tubular product internal diameter, the purpose is to ensure that the contact end of measurement thimble 39 or measurement spacing thimble 20 and tubular product can not insert inside the tubular product, make tubular product measuring true value slightly, the diameter of measurement thimble 39 or measurement spacing thimble 20 is too big can directly lead to waiting to detect regional 44 grow, influence the compactification of whole pipe fitting length integral type detection device, and integral type detection device has avoided feeding mechanism and measuring mechanism's separation, the device occupation space has been saved greatly, further the cost has been saved.
