DETAILED DESCRIPTION

[0041] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0042] like Figures 1 to 5 As shown, the utility model is an automatic detection device for external threaded pipes, comprising:

[0043] A rotating disk 1 has a plurality of groups of detection stations 2 arranged at intervals along the circumferential direction of the rotating disk 1 on its upper surface, and each group of detection stations 2 is provided with three linearly distributed positioning grooves;

[0044] The feeding unit 3 has a feeding channel 4 and a first pneumatic clamp 5. There are three parallel feeding channels 4 on the side of the rotating disk 1. There is a first pneumatic clamp 5 above each feeding channel 4. The first pneumatic clamp 5 is used to synchronously transfer the external threaded pipes to be tested on the three feeding channels 4 to the three positioning grooves.

[0045] An external thread detection unit 6, which has an external thread ring gauge 7 movably arranged above the positioning groove, and is used to detect the external thread pipe on the detection station 2;

[0046] A first collecting unit, which has a first collecting bin 8 arranged on the side of the rotating disk 1 and is used to collect the qualified external threaded pipes on the rotating disk 1;

[0047] The second collecting unit has a second collecting bin 9 arranged on the side of the rotating disk 1 and is used to collect unqualified external threaded pipes on the rotating disk 1 .

[0048] In actual operation, the automated inspection process for externally threaded pipes is as follows:

[0049] The externally threaded tube to be inspected moves in an orderly manner on the feeding channel 4 to the preset designated position. At this time, the first pneumatic clamp 5 in the feeding unit 3 synchronously grabs the externally threaded tubes on the three feeding channels 4 and accurately places them in three positioning grooves distributed linearly on the rotating disk 1; then, the rotating disk 1 transports the externally threaded tube to be inspected on the positioning groove to the position of the external thread inspection unit 6. At this time, the external thread ring gauge 7 engages with the threaded part of the externally threaded tube to measure it in real time to determine whether it meets the specified size and shape standards. After the inspection is completed, the rotating disk 1 continues to rotate and moves the inspected externally threaded tubes to the positions of the first collection unit and the second collection unit in turn. In this process, the qualified externally threaded tubes will be accurately placed in the first collection bin 8, and the unqualified externally threaded tubes will be transferred to the second collection bin 9 when the rotating disk 1 arrives at the second collection unit. This inspection method not only saves manpower and improves inspection efficiency, but also can adapt to the growing output demand and continuously improving quality standards in a large-scale production environment.

[0050] More specifically, the feeding unit 3 includes:

[0051] A vibration plate 10, on which three discharge ports corresponding to the feeding channel 4 are arranged;

[0052] A first support seat 11, which is arranged on the side of the feeding channel 4;

[0053] A first driving member 12, which is horizontally arranged on the first supporting seat 11 and is used to drive the first pneumatic clamping jaw 5 to translate. The first driving member 12 can be a motor or a cylinder;

[0054] The second driving member 13 is vertically arranged at the output end of the first driving member 12, and the first pneumatic clamps 5 are connected to the output end of the second driving member 13, for driving the first pneumatic clamps 5 to rise and fall. The second driving member 13 can be a motor or a cylinder.

[0055] In the automated testing process, the conveying process of the tested external threaded pipe from the vibration plate 10 to the positioning groove is as follows:

[0056] The externally threaded pipe to be tested slides out from the three outlets on the vibration plate 10 in a preset order and smoothly enters the three feeding channels 4 connected thereto. The continuous vibration of the vibration plate 10 enables the pipe to move forward in an orderly manner in the feeding channel 4 to avoid accumulation or jamming.

[0057] When the externally threaded pipes on the three feeding channels 4 each move to the preset grabbing position, the first driving member 12 is started, driving the second driving member 13 connected thereto to move synchronously. As the second driving member 13 moves horizontally, the first pneumatic clamping jaw 5 connected to its output end moves to the top of the externally threaded pipes to be inspected on the three feeding channels 4, respectively, to form a precise alignment. At this time, the second driving member 13 further performs a descending action, driving the first pneumatic clamping jaw 5 to descend to a preset gripping height.

[0058] After reaching the preset clamping position, the first pneumatic clamp 5 clamps the externally threaded pipes on the three feeding channels 4 at the same time, ensuring that the three externally threaded pipes are firmly grasped synchronously. After the clamping action is completed, the second driving member 13 reverses its output direction, driving the first pneumatic clamp 5 and the clamped externally threaded pipe to rise synchronously, so that the pipe is separated from the feeding channel 4;

[0059] While the first pneumatic clamp 5 is carrying the externally threaded pipe upward, the first driving member 12 continues to push the second driving member 13 to translate in the horizontal direction, so as to steadily and accurately move the clamped externally threaded pipe to the position directly above the three positioning grooves on the rotating disk 1;

[0060] Finally, the second driving member 13 performs the descending action again, driving the first pneumatic clamp 5 to descend synchronously together with the clamped external threaded tube, and accurately and synchronously places the three external threaded tubes in the three positioning grooves on the rotating disk 1. The first pneumatic clamp 5 releases the clamping of the external threaded tube to complete the loading process. The whole process reflects the high coordination and precise control of multiple actions by the automated detection system, ensuring the smooth progress of the detection process.

[0061] More specifically, the external thread detection unit 6 includes:

[0062] A second support seat 14, which is arranged on the side of the rotating disk 1;

[0063] A third driving member 15, a plurality of third driving members 15 are vertically arranged on the second supporting seat 14, and are used to drive the external thread ring gauge 7 to rise and fall, and the third driving member 15 can be a motor or a cylinder;

[0064] The fourth driving member 16 is connected to the output end of the third driving member 15, and the output end of the fourth driving member 16 is connected to the external thread ring gauge 7 for driving the external thread ring gauge 7 to rotate. The fourth driving member 16 is preferably a motor.

[0065] When the rotating disk 1 transports the external threaded pipe to be inspected to the position of the external thread inspection unit 6, each external thread ring gauge 7 is just located above an external threaded pipe. At this time, each third driving member 15 on the second support seat 14 starts to drive synchronously, driving the fourth driving member 16 and the thread ring gauge to synchronously descend to the designated inspection position. The fourth driving member 16 synchronously drives the thread ring gauge to rotate, so that the external thread ring gauge 7 engages with the threaded part of the external threaded pipe, and measures it in real time to determine whether it meets the specified size and shape standards. After the inspection is completed, the rotating disk 1 continues to drive the external threaded pipe to rotate.

[0066] More specifically, the first collecting unit includes:

[0067] The second pneumatic clamp 17 is movably arranged above the rotating disk 1 and the first collecting bin 8, and is used to clamp the qualified externally threaded pipe on the rotating disk 1 into the first collecting bin 8;

[0068] A third support seat 18, which is arranged on the side of the rotating disk 1;

[0069] A fifth driving member 19, which is horizontally arranged on the third supporting seat 18, and is used to drive the second pneumatic clamping jaw 17 to translate. The fifth driving member 19 can be a motor or a cylinder;

[0070] The sixth driving member 20 is vertically arranged at the output end of the fifth driving member 19. The output end of the sixth driving member 20 is connected to a plurality of second pneumatic clamps 17 for driving the second pneumatic clamps 17 to move up and down. The sixth driving member 20 may be a motor or a cylinder.

[0071] When the rotating disk 1 transports the tested externally threaded tube to the location of the first collecting unit, the second pneumatic clamps 17 are respectively located above the externally threaded tube on the positioning groove. At this time, the sixth driving member 20 is started, driving the second pneumatic clamps 17 connected to its output end to synchronously descend to the clamping position. When the second pneumatic clamps 17 correspond to a qualified externally threaded tube, the second pneumatic clamps 17 clamp it, and when the second pneumatic clamps 17 correspond to an unqualified threaded tube, the second pneumatic clamps 17 remain stationary to avoid grabbing it, ensuring Only qualified products are processed; when the second pneumatic clamp 17 clamps the qualified product, the sixth drive member 20 drives in the opposite direction to drive the second pneumatic clamp 17 and the clamped external threaded tube to rise. At the same time, the fifth drive member 19 is started, driving the sixth drive member 20 to translate, so that the second pneumatic clamp 17 and the clamped external threaded tube are synchronously translated to just above the first collecting bin 8. The second pneumatic clamp 17 releases its grip on the external threaded tube, and the qualified external threaded tube is placed in the first collecting bin 8. The rotating disk 1 continues to transport the unqualified external threaded tube.

[0072] More specifically, the second collecting unit includes:

[0073] The third pneumatic clamp 21 is movably arranged above the rotating disk 1 and the second collecting bin 9, and is used to clamp the unqualified externally threaded pipes on the rotating disk 1 into the second collecting bin 9;

[0074] A fourth support seat 22, which is arranged on the side of the rotating disk 1;

[0075] A seventh driving member 23, which is horizontally arranged on the fourth supporting seat 22, and is used to drive the third pneumatic clamping jaw 21 to translate. The seventh driving member 23 can be a motor or a cylinder;

[0076] The eighth driving member 24 is vertically arranged at the output end of the seventh driving member 23. The output end of the eighth driving member 24 is connected to a plurality of third pneumatic clamps 21 for driving the third pneumatic clamps 21 to move up and down. The eighth driving member 24 can be a motor or a cylinder.

[0077] When the rotating disk 1 transports the externally threaded tube that does not meet the qualification standard to the location of the second collection unit, the third pneumatic clamps 21 are respectively located above the externally threaded tube on the positioning groove. At this time, the eighth driving member 24 is started, driving the third pneumatic clamps 21 connected to its output end to synchronously descend to the clamping position, and the third pneumatic clamps 21 clamp the unqualified externally threaded tube on the positioning groove. The eighth driving member 24 drives in reverse, driving the third pneumatic clamps 21 to rise synchronously, and the clamped externally threaded tube disengages from the positioning groove and rises. At the same time, the seventh driving member 23 is started, driving the eighth driving member 24 to translate in the horizontal direction, so that the third pneumatic clamps 21 and the clamped externally threaded tube translate to just above the second collection bin 9, and the third pneumatic clamps 21 release their grip on the externally threaded tube, and the unqualified externally threaded tube is placed in the second collection bin 9.

[0078] In order to enhance the accurate monitoring of the delivery of the external threaded pipe, the automatic detection device in the present scheme also includes a positioning seat 25, which is located in the middle position of the rotating disk 1 and does not rotate synchronously with the rotating disk 1. A first detection member 26 is arranged on the positioning seat 25, and the first detection member 26 has three probes corresponding to the positioning grooves one by one. Whenever the loading unit 3 delivers the external threaded pipe to be inspected to the positioning groove, the corresponding probe starts the detection program to determine whether the external threaded pipe is accurately in place. This design ensures that the loading unit 3 can always maintain extremely high consistency and accuracy in the process of conveying the external threaded pipe to the positioning groove.

[0079] In order to provide positioning for the external threaded tube on the feeding channel 4, a limiting member 27 is also provided on the feeding channel 4. The limiting member 27 is located at one end of the feeding channel 4 away from the vibration plate 10 and is movably abutted against the external threaded tube on each feeding channel 4, thereby ensuring the position accuracy of the external threaded tube during transmission on the feeding channel 4 and laying a foundation for the smooth progress of subsequent processes.

[0080] In order to accurately monitor whether the externally threaded pipe on the feeding channel 4 has accurately moved to the preset position, a second detection member 28 is provided on one side of the feeding channel 4 , and the second detection member 28 is located on the side of the limiting member 27 .

[0081] In order to monitor the material status in the feeding channel 4 in real time and determine whether it is full of material, a third detection member 29 is provided on one side of the feeding channel 4 close to the vibration plate 10 .

[0082] In order to meet the inspection requirements of external threaded pipes of various specifications, several groups of inspection stations 2 of different specifications are arranged on the rotating disk 1, and the specifications of the positioning grooves of the same group are the same. The inspection stations 2 of different specifications are used to place external threaded pipes of different specifications. The first inspection member 26, the second inspection member 28 and the third inspection member 29 are preferably displacement sensors.
