Technical Field

[0001] This utility model belongs to the field of flange quality inspection technology, specifically a flange quality inspection device. Background Technology

[0002] A flange is a general term that refers to a disc-shaped metal object with several holes around its perimeter for fixing and connecting other things. It is widely used in machinery and is also commonly used to connect various pipes. Because they come in all shapes and sizes, similar items are generally referred to as flanges.

[0003] Existing flange inspection methods mainly rely on the flange's size, surface smoothness, shape, and opening details. However, existing flange inspection devices generally only support one of these aspects, and the process involves many manual operations by staff, resulting in high labor costs.

[0004] Therefore, this utility model provides a flange quality inspection device. Utility Model Content

[0010] Preferably, a positioning post is fixed to the top of the flange tray, and multiple positioning posts are arranged in a circumferential array.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 3 As shown, an embodiment of the present invention provides a flange quality inspection device, comprising a base plate 1, with an inspection box 2 fixedly connected to the top of the base plate 1; limit blocks 4 are fixedly connected to the side wall of the inspection box 2, and multiple limit blocks 4 are arranged in a circumferential array; a movable block 5 is provided inside the limit block 4, and the movable block 5 is configured to correspond to the internal dimensions of the limit block 4; a stress gauge 6 is fixedly connected to one end of the movable block 5, and a stress probe 8 is provided at the output end of the stress gauge 6; a first threaded rod 9 is threadedly connected to the end of the movable block 5 away from the stress gauge 6; a first motor 10 is provided at the end of the first threaded rod 9 away from the movable block 5, and the first threaded rod 9 is rotatably connected to the side wall of the limit block 4, and the first motor 10 is fixedly connected to the side wall of the limit block 4; during operation, the operator can place the flange to be inspected inside the base plate 1, positioning it in the center of a circularity measuring assembly composed of multiple limit blocks 4, movable blocks 5, stress gauges 6, stress probes 8, first threaded rods 9, and first motors 10, and finally measure the flange by means of the same... Multiple first motors 10 are driven to make multiple stress probes 8 contact and compress with the flange. If the shape of the flange itself conforms to the specifications, the difference in stress values ​​displayed by multiple stress gauges 6 should be within the error range. During the process, whenever the first motor 10 fixed to the side wall of the limiting block 4 is driven, the first threaded rod 9 fixed to the output end of the first motor 10 will rotate. Since the movable block 5 and the limiting block 4 are in a sliding connection relationship, and the movable block 5 and the first threaded rod 9 are in a threaded connection relationship, the movable block 5 will drive the stress gauges 6 and stress probes 8 to move accordingly as the first threaded rod 9 rotates. This step determines whether the shape of the flange conforms by setting multiple stress gauges 6 and stress probes 8 to contact the side wall of the flange. By setting multiple first motors 10 and first threaded rods 9, the stress gauges 6 and stress probes 8 can move, which enhances the flexibility and practicality of the device and helps to avoid the device structure from hindering the flange detection.

[0026] like Figure 4 and Figure 5As shown, a lifting bracket 14 is provided at the bottom of the testing box 2; a second threaded rod 12 is rotatably connected to the side wall of the lifting bracket 14; a first limiting rod 13 is fixedly connected to the side wall of the lifting bracket 14, and the first limiting rod 13 is positioned corresponding to the second threaded rod 12; a second motor 15 is provided at the end of the second threaded rod 12; a transport block 11 is threadedly connected to the side wall of the second threaded rod 12, and the transport block 11 is slidably connected to the first limiting rod 13; a flange tray 16 is fixedly connected to the top of the transport block 11; during operation, the operator can place the flange to be tested on the top of the flange tray 16, and drive the second motor 15 to move the transport block 11 to a predetermined position inside the testing box 2, thereby placing the flange placed on the top of the flange tray 16. As the disc moves to the detection position, whenever the second motor 15, fixed to the side wall of the lifting bracket 14, rotates, the second threaded rod 12, fixed to the output end of the second motor 15, will rotate. At this time, since the transport block 11 is threadedly connected to the second threaded rod 12 and slidably connected to the first limit rod 13, the transport block 11 will move horizontally along with the rotation of the second threaded rod 12. This step, by setting the transport block 11 and the flange tray 16 to carry the flange, and by setting the second motor 15, the second threaded rod 12 and the first limit rod 13, enables the transport block 11 and the flange tray 16 to move, thereby transporting the flange to the detection position. This enhances the automation level of the device, which is conducive to improving work efficiency and reducing labor costs.

[0027] like Figure 1 , Figure 2 and Figure 4As shown, a fixed bracket 3 is fixedly connected to the top of the base plate 1, and two fixed brackets 3 are arranged correspondingly; a second limiting rod 19 is fixedly connected between the fixed bracket 3 and the base plate 1; a third threaded rod 20 is rotatably connected between the base plate 1 and the fixed bracket 3; a third motor 21 is provided at the end of the third threaded rod 20, and the third motor 21 is fixedly connected to the top of the fixed bracket 3; the lifting bracket 14 is slidably connected to the second limiting rod 19. The third threaded rod 20 is threadedly connected to the flange. During operation, whenever the flange moves to the predetermined position under the drive of the second motor 15, the operator can first clamp multiple stress gauges 6 and stress probes 8 onto the side wall of the flange. Then, by driving the third motor 21, the flange tray 16 loses contact with the flange, thereby avoiding the flange tray 16's support from affecting the flange inspection. During the process, whenever the third motor 21, which is fixed to the top of the fixed bracket 3, is driven, the third threaded rod 20, which is threadedly connected to the lifting bracket 14, will rotate. Since the lifting bracket 14 is simultaneously restricted by the two second limit rods 19 that are slidably connected to it, the lifting bracket 14 will move vertically under the action of the third motor 21. This step, by setting the third motor 21, the second limit rods 19, and the third threaded rod 20, makes the height of the lifting bracket 14 controllable, thereby controlling the position of the transport block 11 and the flange tray 16, preventing the flange tray 16 from contacting the bottom of the flange during the inspection process, which helps to improve the inspection accuracy of the device.

[0028] like Figure 4 and Figure 5 As shown, a support plate 7 is fixed to the side wall of the stress gauge 6; a lifting groove 18 is provided on the side wall of the flange tray 16, and multiple lifting grooves 18 are set to correspond to the size of the support plate 7; during operation, whenever the flange tray 16 transports the flange to the predetermined position, the support plate 7 fixed to the side wall of the stress gauge 6 can contact the bottom of the flange through multiple lifting grooves 18, and finally lift the flange to fix the bracket 3; this step, by setting the support plate 7 to lift the flange, prevents it from falling, and by setting the lifting grooves 18, prevents the flange tray 16 from obstructing the support plate 7, thus improving the stability and reliability of the device.

[0029] like Figure 5 As shown, a positioning post 17 is fixed to the top of the flange tray 16, and multiple positioning posts 17 are arranged in a circumferential array. During operation, the operator can check whether the opening on the flange surface is qualified while placing the flange on the top of the flange tray 16. The multiple positioning posts 17 are set to correspond to the surface opening of the standard flange. This step enhances the functionality of the device by setting multiple positioning posts 17 to check whether the opening on the flange surface is qualified, which helps to reduce the inspection process of flange inspection and increase the work efficiency of the operator.

[0030] like Figure 1 and Figure 2 As shown, a connecting block 22 is fixed to the side wall of the base plate 1, and multiple connecting blocks 22 are arranged in a corresponding manner. During operation, the operator can fix multiple connecting blocks 22 to the ground with bolts, thereby fixing the device to the ground. This step, by setting multiple connecting blocks 22 to connect the device to the ground, helps to improve the stability of the device, reduce device shaking, and maintain the accuracy of the flange detection of the device.

[0031] like Figures 1 to 5 As shown, the base plate 1, detection box 2, fixed bracket 3, lifting bracket 14, flange pallet 16, and transport block 11 are made of stainless steel. During operation, the use of stainless steel in the base plate 1, detection box 2, fixed bracket 3, lifting bracket 14, flange pallet 16, and transport block 11 allows the advantages of stainless steel, such as high strength and resistance to rust, to be utilized. This step maintains the structural strength of the device by using stainless steel in the base plate 1, detection box 2, fixed bracket 3, lifting bracket 14, flange pallet 16, and transport block 11, keeps the surface of the device components smooth, and reduces the device's maintenance requirements and difficulty.

[0032] During operation, the operator places the flange to be tested inside the base plate 1, positioning it in the center of a circularity measuring assembly consisting of a limiting block 4, a movable block 5, a stress gauge 6, a stress probe 8, a first threaded rod 9, and a first motor 10. Then, by simultaneously driving multiple first motors 10, multiple stress probes 8 come into contact with and are pressed against the flange. If the flange's shape conforms to specifications, the difference in stress values ​​displayed by the multiple stress gauges 6 should be within the error range. During the process, whenever a first motor 10 fixed to the side wall of the limiting block 4 is driven, the first threaded rod 9 fixed to the output end of the first motor 10 will rotate. Since the movable block 5 and the limiting block 4 are in a sliding connection relationship, and the movable block 5 and the first threaded rod 9 are in a sliding connection relationship... The first threaded rod 9 is threadedly connected. As the first threaded rod 9 rotates, the movable block 5 will cause the stress gauge 6 and stress probe 8 to move accordingly. The operator can place the flange to be tested on top of the flange tray 16 and drive the second motor 15 to move the transport block 11 to a predetermined position inside the testing box 2, thereby moving the flange placed on top of the flange tray 16 to the testing position. During this process, whenever the second motor 15, fixed to the side wall of the lifting bracket 14, rotates, the second threaded rod 12, fixed to the output end of the second motor 15, will rotate. At this time, since the transport block 11 is threadedly connected to the second threaded rod 12 and slidably connected to the first limit rod 13, the second threaded rod 12 will rotate. The rotation of rod 12 causes the transport block 11 to move horizontally. Whenever the flange moves to a predetermined position under the drive of the second motor 15, the operator can first clamp multiple stress gauges 6 and stress probes 8 onto the side wall of the flange. Then, by driving the third motor 21, the flange tray 16 loses contact with the flange, thus preventing the support of the flange tray 16 from affecting the flange inspection. During this process, whenever the third motor 21, fixed to the top of the fixed bracket 3, is driven, the third threaded rod 20, which is threadedly connected to the lifting bracket 14, will rotate. Because the lifting bracket 14 is simultaneously restricted by two second limit rods 19 that are slidably connected to it, the lifting bracket 14 will move under the action of the third motor 21. The vertical movement occurs when the flange pallet 16 transports the flange to the predetermined position. The support plate 7 on the side wall of the stress gauge 6 where it is fixed can contact the bottom of the flange through multiple lifting slots 18, and finally lift the flange to fix the bracket 3. The operator can check whether the opening on the flange surface is qualified while placing the flange on the top of the flange pallet 16. Multiple positioning columns 17 are set to correspond to the opening on the surface of the standard flange. The operator can fix multiple connecting blocks 22 to the ground with bolts, thereby fixing the device to the ground. The stainless steel base plate 1, inspection box 2, fixing bracket 3, lifting bracket 14, flange pallet 16, and transport block 11 can take advantage of the high strength and rust resistance of stainless steel.
