Description

Technical Field

[0001] The utility model relates to the technical field of non-standard automation equipment, in particular to automatic detection equipment for threaded pipes. Background Art

[0002] Threaded pipe is a pipe with an internal thread structure. After its production is completed, the internal thread of the threaded pipe must be strictly inspected for quality. The inspection process usually requires that all necessary internal thread measurements be completed first, and then the qualified threaded pipes that pass the inspection are transferred to a special marking process. In the traditional operation mode, this process involves two independent workstations. First, the threaded pipes are inspected one by one at the inspection station, and then the qualified products are transferred to the marking area for further processing. This method not only occupies a certain amount of workshop space, but also in traditional processes, the inspection of thread size and accuracy of threaded pipes is generally carried out manually, that is, the operator uses a thread gauge to measure the threaded pipes one by one. However, this method is inefficient and is more suitable for small-batch production or random sampling inspection. It is difficult to meet the needs of efficient and continuous quality inspection of large-scale threaded pipe production lines. Utility Model Content

DETAILED DESCRIPTION

[0040] 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.

[0041] An automatic inspection device for threaded pipes, comprising: a rotating disk 1, a plurality of inspection stations 2 are arranged at intervals along the circumference of the rotating disk 1 on its upper surface, and the threaded pipe to be inspected is vertically fixed on the inspection station 2; a feeding unit 3, which is arranged on the side of the rotating disk 1, and the feeding unit 3 is used to transport the threaded pipe to be inspected to the inspection station 2; a threaded hole inspection unit 4, which has a thread gauge 5 and a thread stop gauge 6 movably arranged above the inspection station 2, and the thread gauge 5 and the thread stop gauge 6 are both used to inspect the threaded pipe on the inspection station 2; a sorting unit 4, which is provided with a thread gauge 5 and a thread stop gauge 6 movably arranged above the inspection station 2, and the thread gauge 5 and the thread stop gauge 6 are used to inspect the threaded pipe on the inspection station 2; Unit 7, which is arranged on the side of the rotating disk 1, and the sorting unit 7 is used to sort the threaded pipes that are qualified and unqualified for inspection; the marking unit 8, which has a marking machine 9 arranged on the side of the rotating disk 1 and a clamping member 10 movably arranged above the rotating disk 1 and the sorting unit 7, the marking machine 9 is used to mark on the threaded pipe, and the clamping member 10 has a first clamping state arranged horizontally and a second clamping state arranged vertically, the first clamping state is used to clamp the threaded pipe on the inspection station 2, and the second clamping state is used to place the threaded pipe horizontally in the sorting unit 7.

[0042] Based on the above embodiments, an exemplary structure of this solution is as follows: Figures 1 to 7As shown, six inspection stations 2 are arranged on the rotating disk 1, and preferably, each inspection station 2 is equipped with a three-jaw chuck for fixing the threaded tube. In the work process, the feeding unit 3 transports the threaded tubes to be inspected one by one to the nearest three-jaw chuck, so that the threaded tube can stand vertically on the chuck, so that the threaded hole of the threaded tube is vertically arranged upward, which is convenient for the next inspection step. Once the threaded tube is fixed on a certain three-jaw chuck, the rotating disk 1 will rotate and rotate the next idle three-jaw chuck to the position docking with the feeding unit 3, so as to realize the continuous inspection of large quantities of threaded tubes in this cycle. When the threaded tube is fixed by the three-jaw chuck and driven by the rotating disk 1 to the side of the threaded hole inspection unit 4, the thread gauge 5 and the thread stop gauge 6 on the thread inspection unit will strictly inspect the threaded hole of the threaded tube. After the inspection is completed, the rotating disk 1 continues to drive the inspected threaded tube to rotate to the marking unit 8, and the threaded tube that has passed the inspection is marked. As for the unqualified threaded pipes, the clamping member 10 moves them to the sorting unit 7 for processing. The sorting unit 7 distinguishes the unqualified threaded pipes according to the test results of the thread gauge 5 and the thread stop gauge 6. The clamping member 10 is designed with a first clamping state in the horizontal direction to ensure that the threaded pipe can still be kept in a vertical state when it is removed from the three-jaw chuck, so that the marking machine 9 can accurately mark the outer wall of the threaded pipe; at the same time, the clamping member 10 can also switch to a second clamping state in a vertical setting, so that the threaded pipe can be smoothly rotated to a horizontal position, which is convenient for the placement and classification of the threaded pipe.

[0043] In this solution, by setting a rotating disk 1, a feeding unit 3, a thread detection unit, a sorting unit 7 and a marking unit 8, automatic detection and marking operations of threaded pipes are realized, and the working efficiency of threaded pipe detection and marking operations is improved to adapt to the detection and marking operations of large quantities of threaded pipes. In addition, the detection and marking operations are combined to reduce the space occupied in the workshop and improve the utilization rate of the space in the workshop.

[0044] Specifically, the marking unit 8 of the present scheme includes: a first support frame 11; a first driving member 12, which is horizontally arranged on the first support frame 11; a second driving member 13, which is vertically arranged at the output end of the first driving member 12; a first movable seat 14, which is connected to the output end of the second driving member 13, and a rotating shaft is rotatably arranged on the first movable seat 14, and the clamping member 10 is fixed on the rotating shaft; a rotating block 15, which is fixedly connected to one end of the rotating shaft; a third driving member 16, which is connected to the first movable seat 14 and the output end of the third driving member 16 is connected to the rotating block 15, and is used to drive the rotating block 15 to rotate on the first movable seat 14.

[0045] Preferably, the first driving member 12 and the second driving member 13 are both linear guides, and the third driving member 16 is preferably a cylinder. When working, the two linear guides drive the first moving seat 14 to move in the horizontal and vertical directions, thereby driving the clamping member 10 to move in these two directions, thereby realizing the handling of the threaded pipe by the clamping member 10. The third driving member 16 drives the rotating shaft to rotate on the first moving seat 14 through the rotating block 15, thereby switching the clamping member 10 between the first clamping state and the second clamping state, thereby realizing the conversion of the threaded pipe between the vertical state and the horizontal state. Preferably, the clamping member 10 is a pneumatic clamp.

[0046] In addition, the sorting unit 7 includes: a first conveyor belt 17, which is used to convey threaded pipes that have passed the inspection; two discharge channels 18, one end of the two discharge channels 18 is connected to form a feed channel 19, and the two discharge channels 18 are respectively used to discharge threaded pipes that have failed the through gauge inspection and the stop gauge inspection; a dividing piece 20, which is movably arranged on the feed channel 19, and is used to push the threaded pipe placed on the feed channel 19 into one of the discharge channels 18.

[0047] After the threaded hole inspection of the threaded pipe is completed, the clamping member 10 will transfer the threaded pipe that has passed the inspection to the side of the marking machine 9, and mark the outer wall of the threaded pipe through the marking machine 9. Then, the clamping member 10 switches from the first clamping state to the second clamping state, so that the threaded pipe smoothly transitions from the vertical state to the horizontal state. Subsequently, the clamping member 10 accurately places the marked threaded pipe on the first conveyor belt 17. For threaded pipes that fail the inspection, they can be subdivided into two categories according to the inspection results: the thread gauge 5 fails to meet the standard and the thread gauge 6 fails to meet the standard. To this end, the present scheme sets up two independent discharging channels, which are used to store these two types of unqualified threaded pipes, respectively, so as to facilitate the subdivision and classification of unqualified products. The material dividing member 20 pushes different types of unqualified threaded pipes into the corresponding discharging channel 18 through corresponding actions, thereby realizing an accurate sorting function.

[0048] A fourth driving member 21 is fixed above the two discharge channels 18 , and the material dividing member 20 is connected to the output end of the fourth driving member 21 to drive the material dividing member 20 to move in the feed channel 19 . Preferably, the fourth driving member 21 is a cylinder.

[0049] In addition, the threaded hole detection unit 4 includes: a second support frame 22 and a third support frame 23 that are adjacent to each other, and a fifth driving member 24 and a plurality of guide columns 25 that are uprightly arranged on the second support frame 22 and the third support frame 23; a second movable seat 26, and a second movable seat 26 that can be movably arranged on the second support frame 22 and the third support frame 23, and a guide sleeve 27 that is sleeved on the outer side of the guide column 25 is fixed on the second movable seat 26; each second movable seat 26 is provided with a sixth driving member 28, and the sixth driving member 28 is used to drive the through gauge and the stop gauge to rotate.

[0050] The second support frame 22 and the third support frame 23 are used to support the remaining components of the thread detection unit. When working, the fifth driving member 24 drives the second moving seat 26 to move in the vertical direction, thereby driving the thread gauge 5 and the thread stop gauge 6 to move closer to or farther from the threaded tube. The guide column 35 and the guide sleeve 27 are used to provide guidance for the movement of the second moving seat 26. The output ends of the two sixth driving members 28 are respectively connected to the thread gauge 5 and the thread stop gauge 6, thereby realizing the rotation of the thread gauge 5 and the thread stop gauge 6. Preferably, the fifth driving member 24 is a cylinder, and the sixth driving member 28 is a motor.

[0051] Finally, the loading unit 3 includes: a second conveyor belt 29, on which a plurality of three-jaw chucks 30 are movably arranged, and the threaded pipe to be inspected is fixed on the three-jaw chuck 30; a fourth support frame 31, which is vertically arranged on the side of the rotating disk 1; a seventh driving member 32, which is horizontally arranged on the fourth support frame 31; an eighth driving member 33, which is vertically arranged at the output end of the seventh driving member 32; a third movable seat 34, which is connected to the output end of the eighth driving member 33, and a pneumatic clamp 35 is fixed on the third movable seat 34, and the pneumatic clamp 35 is used to transport the threaded pipe on the three-jaw chuck to the inspection station 2.

[0052] During operation, the threaded tube to be inspected is placed on the three-jaw chuck 30 on the second conveyor belt 29. The seventh driving member 32 and the eighth driving member 33 work together to drive the third movable seat 34 to move in the vertical and horizontal directions, thereby driving the pneumatic clamp 35 to move synchronously in these two directions, and finally realizing the process of smoothly transferring the threaded tube from the second conveyor belt 29 to the rotating disk 1.
