[0032] In the existing flange production and processing process, the position detection of the threaded holes on the flange usually relies on manual operation. The traditional method is for workers to use tools such as vernier calipers and plug gauges to measure and check whether the threaded holes on the flange meet the design requirements. This method is not only inefficient, but also greatly affected by human factors, and it is difficult to ensure the consistency and accuracy of the test results. Especially in the context of large-scale production and high-precision requirements, manual inspection cannot meet the requirements of modern industry for quality and efficiency. In addition, manual inspection requires a lot of manpower costs, which increases the operating pressure of production enterprises. Therefore, how to realize the automation of the position detection of threaded holes on flanges has become a key issue in improving production efficiency and product quality. In the prior art, although there are some automated detection equipment, these equipment are often complex in structure, high in cost, and have a limited scope of application, and cannot well meet the diverse needs in actual production.

[0033] Therefore, developing an efficient, accurate and economical automated detection method and technology is of great practical significance.

[0034] Please refer to Figure 1-Figure 2This embodiment provides a workpiece threaded hole position detection device, which can effectively improve the above-mentioned technical problems. It can automatically detect the position of the threaded hole on the flange 101, with efficient and accurate detection and easy use.

[0035] Please refer to Figure 1 The present embodiment provides a workpiece threaded hole position detection device including a conveying module 10, a detection module 20, a gripping module 30 and a control module, which are used to convey the workpiece to the detection station, the detection module 20 is installed at the detection station, the detection module 20 is used to detect the threaded hole position of the workpiece, the gripping module 30 is movably arranged relative to the detection module 20, the gripping module 30 is used to grip the workpiece on the conveying module 10 to the detection module 20, and the control module is connected to the conveying module 10, the detection module 20 and the gripping module 30 at the same time.

[0036] It should be noted that the workpiece threaded hole position detection device provided in this embodiment is mainly used to detect the threaded holes of the flange 101. In other embodiments, the workpiece threaded hole position detection device can also be used to detect the threaded hole position on other workpieces, which will not be described in detail here.

[0037] In this embodiment, the detection module 20 includes a detection platform 21 and a detector, the detector is movably arranged on the detection platform 21, the detection platform 21 is used to carry the workpiece, the detector is connected to the control module, and the detector is used to detect the workpiece placed on the detection platform 21 under the drive of the control module. Among them, the workpiece is placed on the top surface of the detection platform 21, and the shape of the top surface of the detection platform 21 is adapted to the shape of the flange 101.

[0038] Specifically, the detector includes an imaging module and a light source. The light source is used to emit light toward the workpiece. The imaging module is used to take a picture of the workpiece and transmit the imaging information to the control module.

[0039] In this embodiment, the imaging module is a camera.

[0040] When working, the light source emits light toward the workpiece, so that the imaging module can clearly take a picture of the threaded hole. After taking the picture, the imaging module transmits the imaging information to the control module. The control module is used to compare the captured picture with the preset picture to obtain the detection result to detect whether the position of the threaded hole of the flange 101 meets the standard.

[0041] It should also be noted that when the workpiece is being inspected, since the detector needs to enter the threaded hole for inspection, the placement of the workpiece on the inspection table 21 is very important. Only after the threaded hole of the workpiece and the position of the detector are aligned, the detector can accurately detect the position of the threaded hole. In order to ensure successful inspection, the inspection module 20 provided in this embodiment also includes a sensor and a driver. The sensor and the driver are both connected to the control module. The driver is used to connect to the workpiece, thereby driving the workpiece to rotate relative to the inspection table 21. The control module is used to drive the driver to start when the sensor signal is not received, so that the driver drives the workpiece to rotate.

[0042] Specifically, the sensor is a proximity switch. When the position of the threaded hole of the workpiece is aligned with the position of the detector, the workpiece will block the sensor, thereby causing the sensor to send a signal.

[0043] During operation, the grabbing module 30 places the workpiece on the detection table 21. When the control module does not receive a signal from the sensor, it indicates that the workpiece is not at the detection station at this time. At this time, the control module controls the driver to start, and the driver drives the workpiece to rotate on the detection table 21; when the workpiece rotates to the detection station, the workpiece will block the proximity switch. At this time, the proximity switch sends a signal to the control module. After receiving the signal from the proximity switch, the control module controls the driver to stop working.

[0044] In this embodiment, the driver is a driving motor.

[0045] It can be understood that a through hole is passed through the detection table 21 , and the driving end of the driver is connected to the workpiece through the through hole, thereby driving the workpiece to rotate on the detection table 21 .

[0046] It should also be explained that the grabbing module 30 includes a grabbing cylinder and at least two struts 31. The grabbing cylinder is connected to the control module. At least two struts 31 are connected to the grabbing cylinder. The grabbing cylinder drives at least two struts 31 to perform lifting movements. At least two struts 31 are used to abut against the workpiece.

[0047] Optionally, the grabbing module 30 further includes a translation cylinder, which is connected to the control module and is simultaneously connected to at least two support rods 31 , and is used to drive at least two support rods 31 to move closer to or away from each other.

[0048] In this embodiment, there are three support rods 31. In other embodiments, the number of support rods 31 may be increased or decreased, which is not specifically limited here.

[0049] More specifically, the conveying module 10 includes a conveying belt and a clamping block, wherein the clamping block is installed on the conveying belt and is used for clamping with the workpiece.

[0050] In this embodiment, the conveyor belt is connected to the control module, and the control module drives the conveyor belt to move. When the workpiece is placed on the conveyor belt, the workpiece is clamped on the clamping block.

[0051] There are several card blocks, which are arranged in sequence and at intervals along the conveying direction of the conveyor belt.

[0052] In this embodiment, the clamping block is a circular ring structure, and a plurality of clamping slots are arranged on the clamping block, and the plurality of clamping slots are arranged at intervals along the circumferential direction, and when the workpiece is placed on the clamping block, the workpiece is clamped in the plurality of clamping slots at the same time, thereby realizing clamping. There are three clamping slots.

[0053] In other embodiments, the number of card slots may be increased or decreased, which is not specifically limited herein.

[0054] In this embodiment, the workpiece threaded hole position detection equipment also includes a positioning table 40 and a positioning robot 50. The positioning table 40 and the detection table 21 are arranged at intervals. The workpiece after detection is moved to the positioning table 40 through the grasping module 30, and the positioning robot 50 positions the workpiece.

[0055] Specifically, the positioning robot 50 includes a lifting cylinder, an inner support block, a positioning column and a step block. The lifting cylinder is connected to the step block and is used to drive the step block to perform lifting and lowering movements. The step block is provided with three steps. The positioning column is arranged in the middle of the step block, and the inner support block is located outside the step block. The lifting cylinder drives the step block to move down to the position of the flange 101. The three steps of the step block are abutted and positioned with the internal structure of the flange 101 in turn. The positioning column and the inner support block follow the step block into the inner circle of the flange 101. After the flange 101 is positioned, the inner support block abuts with the inner circle of the flange 101, and the lifting cylinder drives the step block to rise, thereby causing the inner support block to drive the flange 101 to rise.

[0056] In addition, the workpiece threaded hole position detection device also includes an airtightness detection device, and the positioning robot 50 moves the flange 101 to the airtightness detection device for airtightness detection.

[0057] It should be noted that the airtightness detection device is a conventional detection device. Before the flange 101 enters the airtightness detection device, the shell of the airtightness detection device rises under the drive of the cylinder, and the positioning manipulator 50 drives the flange 101 to move into the inspection fixture of the airtightness detection device to ensure that the flange 101 can be smoothly placed in the inspection fixture, and then the shell of the airtightness detection device descends with the cylinder, and finally the airtightness detection of the workpiece is performed.

When in use, the conveying module 10 continuously transports the workpiece, and when the workpiece follows the conveying module 10 to reach the detection station, the control module drives the grabbing module 30 to grab the workpiece on the conveying module 10 and move the workpiece to the detection module 20.
