Description

Technical Field

[0001] This utility model relates to the field of weld inspection technology, and specifically to a novel weld inspection device. Background Technology

[0002] In industrial processing and production, welding is often used to combine and connect two metal components. For example, welding technology can be used in the production and processing of flange rings. After welding, the components need to be inspected to check the effect of the weld. Common inspection equipment is usually an ultrasonic probe.

[0003] A flange weld inspection device with publication number CN117191939A includes a base, a probe, a rotating mechanism, and a coating mechanism fixedly connected to the base for sliding the probe at the weld. A clamping mechanism, located at the upper end of the base, fixes the flange at the upper end of the base. By placing the flange on the inner wall of the clamping mechanism, ultrasonic waves are facilitated to transmit through the weld. The rotating mechanism slides the probe at the weld in a wave-like motion, which is beneficial for detecting linear gaps in the weld's inner wall. While the probe slides, the coating component applies a measured amount of coupling agent to the weld in front of the rotating probe, allowing workers to directly observe the curve changes displayed on the instrument without simultaneously observing the sliding position of the probe and the weld. This reduces the workload for workers and prevents the overlooking of linear gap curve changes during repeated observations, thus affecting the quality of the flange.

[0004] The aforementioned prior art has some drawbacks. When installing flange rings, the internal fixing and extrusion structure is relatively large, making it inconvenient to fix small-sized flange rings. Furthermore, it can only be fixed inside the flange ring, making it difficult to adjust the fixing position. This results in inconvenience during actual fixing. Moreover, the device can only inspect the inner and outer welds separately during testing, which is not very efficient. Adjusting the position is also easily affected by the internal fixing device, making operation inconvenient. Utility Model Content

[0005] The purpose of this invention is to provide a new type of weld inspection device that solves the problems of existing inspection devices, such as inconvenience in fixing the workpiece to be inspected, low inspection efficiency, and inconvenience in adjusting the inspection position.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a novel weld inspection device, comprising a workbench, a rotating gear disk rotatably connected to the top of the workbench, a plurality of sliding frames provided on the top of the rotating gear disk, a lead screw being provided through the interior of each sliding frame, an electric adjustment push rod provided on both sides of the workbench away from the rotating gear disk, and an ultrasonic probe provided on the side of the electric adjustment push rod close to the rotating gear disk.

[0007] The sliding frame is slidably connected to an extrusion block, and a fixing bolt is threadedly connected to the edge of the sliding frame near the rotating toothed disk. The bottom of the sliding frame is rotatably connected to the rotating toothed disk.

[0008] The top of the electric adjusting push rod is rotatably connected to a fixed ring, and an adjusting rod is slidably connected inside the fixed ring. One end of the adjusting rod is fixedly connected to a fixed block.

[0009] An electric lifting rod is fixedly installed inside the fixed block. Clamping plates are provided on both sides of one side of the ultrasonic probe. A threaded rod is rotatably connected to the bottom protruding end of the electric lifting rod. Both sides of the threaded rod are threadedly connected to the clamping plates.

[0010] Preferably, a drive gear is meshed with one side of the rotating gear disk, and a drive motor is installed at the bottom of the worktable near the rotating gear disk and the drive gear.

[0011] Preferably, the top of the rotating gear disk is rotatably connected to multiple sliding frames via a rotating shaft, one end of the pressing block penetrates the interior of the sliding frame and is pressed against the top of the rotating gear disk, and the center of the drive gear is fixedly connected to the power output end of the drive motor.

[0012] Preferably, one end of the lead screw passes through the interior of the sliding frame and is connected to a connecting gear, and the lead screw passes through the interior of the extrusion block and is threadedly connected to the extrusion block.

[0013] Preferably, a rotating gear is provided at the top center of the rotating gear disk, the power output end of the drive motor passes through the inside of the worktable and the rotating gear disk and is fixedly connected to the rotating gear, and the top of the rotating gear is meshed with multiple connecting gears.

[0014] Preferably, the top of the fixing ring is threaded with a compression bolt, one end of which passes through the fixing ring and fits against the adjusting rod.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. The fixing bolts compress the rotating gear disc, thereby limiting and fixing the sliding frame to prevent movement. It allows the corresponding flange ring to be easily placed on the sliding frame at the top of the rotating gear disc. It can start the drive motor at the bottom of the rotating gear, which in turn drives the connecting gear to rotate, thereby driving the lead screw to rotate. The lead screw can drive the extrusion block to slide along the sliding frame, so that the extrusion block can easily fit and compress the bottom of the flange ring, either externally or internally, thus fixing the flange ring at the center of the rotating gear disc. It can effectively fix flange rings of different sizes.

[0017] 2. The welding position is detected by an ultrasonic probe. An electric adjusting push rod drives the fixed ring to rise, which in turn drives the fixed block to rise via the adjusting rod. This, in turn, moves the electric lifting rod, which in turn lowers the ultrasonic probe at the bottom, thus adjusting the detection position. The clamping plate can be rotated around the threaded rod to adjust the angle of the ultrasonic probe, allowing for different detection angles. Furthermore, the drive motor rotates the drive gear, which in turn rotates the rotating gear plate and the connecting gear, which in turn causes the sliding frame to rotate the flange workpiece at the top, thus achieving circumferential detection, which is very convenient.

Detailed Implementation

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-5The illustrated novel weld inspection device includes a workbench 1, with a rotating gear disk 101 rotatably connected to the top of the workbench 1. Multiple sliding frames 2 are mounted on the top of the rotating gear disk 101, and each sliding frame 2 has a lead screw 3 running through its interior. Electric adjusting push rods 5 are mounted on both sides of the workbench 1 away from the rotating gear disk 101, and ultrasonic probes 4 are mounted on the side of each electric adjusting push rod 5 closest to the rotating gear disk 101. A pressing block 202 is slidably connected inside each sliding frame 2, and a fixing bolt 20 is threadedly connected to the edge of each sliding frame 2 near the rotating gear disk 101. 1. The bottom of the sliding frame 2 is rotatably connected to the rotating gear disk 101; the top of the electric adjusting push rod 5 is rotatably connected to the fixing ring 501, the inside of the fixing ring 501 is slidably connected to the adjusting rod 503, and one end of the adjusting rod 503 is fixedly connected to the fixing block 504; the inside of the fixing block 504 is fixedly installed with the electric lifting rod 403, and clamping plates 401 are provided on both sides of one side of the ultrasonic probe 4. The bottom protruding end of the electric lifting rod 403 is rotatably connected to the threaded rod 402, and both sides of the threaded rod 402 are threadedly connected to the clamping plates 401.

[0028] The drive motor 103 at the bottom of the rotating gear 302 is started, which in turn drives the connecting gear 301 to rotate, thereby rotating the lead screw 3. The lead screw 3 drives the pressing block 202 to slide along the sliding frame 2, allowing the pressing block 202 to easily fit and press against the outside or inside of the bottom end of the flange ring, thus fixing the flange ring at the center of the rotating gear disk 101. The electric lifting rod 403 is started to lower the ultrasonic probe 4 at the bottom, thereby adjusting the detection position. The clamping plate 401 can be rotated around the threaded rod 402 to adjust the angle of the ultrasonic probe 4, allowing for different detection angles. The drive motor 103 also drives the drive gear 102 to rotate, which in turn rotates the rotating gear disk 101 and the connecting gear 301, causing the sliding frame 2 to rotate the flange workpiece at the top, thus achieving a convenient circumferential detection.

[0029] like Figure 2 , Figure 4As shown, a drive gear 102 is meshed with one side of the rotating gear disk 101. A drive motor 103 is installed at the bottom of the worktable 1 near the rotating gear disk 101 and the drive gear 102. The top of the rotating gear disk 101 is rotatably connected to multiple sliding frames 2 via a rotating shaft. One end of the pressing block 202 penetrates the interior of the sliding frame 2 and presses against the top of the rotating gear disk 101. The center of the drive gear 102 is fixedly connected to the power output end of the drive motor 103. By rotating the sliding frame 2, the position of the multiple sliding frames 2 is adjusted. Then, by rotating the fixing bolt 201, the fixing bolt 201 presses against the rotating gear disk 101, thereby limiting and fixing the sliding frame 2 to prevent movement. This allows the corresponding flange ring to be easily placed on the sliding frame 2 at the top of the rotating gear disk 101.

[0030] like Figure 2 , Figure 3 As shown, one end of the lead screw 3 passes through the interior of the sliding frame 2 and is connected to the connecting gear 301. The lead screw 3 passes through the interior of the extrusion block 202 and is threadedly connected to the extrusion block 202. A rotating gear 302 is provided at the top center of the rotating gear disk 101. The power output end of the drive motor 103 passes through the interior of the worktable 1 and the rotating gear disk 101 and is fixedly connected to the rotating gear 302. The top of the rotating gear 302 is meshed with multiple connecting gears 301. When the drive motor 103 at the bottom of the rotating gear 302 is started, the rotating gear 302 is rotated, which in turn drives the connecting gear 301 to rotate, thereby driving the lead screw 3 to rotate. The lead screw 3 can drive the extrusion block 202 to slide along the sliding frame 2, so that the extrusion block 202 can be easily pressed against the outside or inside of the bottom end of the flange ring.

[0031] like Figure 1 , Figure 5 As shown, a clamping bolt 502 is threadedly connected to the top of the fixing ring 501. One end of the clamping bolt 502 passes through the fixing ring 501 and is in contact with the adjusting rod 503. The fixing ring 501 is driven to rise by the electric adjusting push rod 5, which in turn causes the fixing block 504 to rise through the adjusting rod 503, thereby driving the electric lifting rod 403 to move. At the same time, the electric lifting rod 403 can also be activated to drive the ultrasonic probe 4 at the bottom to descend, thereby adjusting the detection position. Moreover, the clamping plate 401 can be rotated around the threaded rod 402 to adjust the angle of the ultrasonic probe 4, allowing for different detection angles to be adjusted by rotation.

[0032] In use, the sliding frame 2 can be easily rotated according to the usage requirements, thereby adjusting the position of multiple sliding frames 2. Then, the fixing bolt 201 is rotated, causing the fixing bolt 201 to press against the rotating gear disk 101, thereby limiting and fixing the sliding frame 2 to prevent movement. The corresponding flange ring can be easily placed on the sliding frame 2 at the top of the rotating gear disk 101. The drive motor 103 at the bottom of the rotating gear 302 can be started, causing the rotating gear 302 to drive the connecting gear 301 to rotate, thereby driving the lead screw 3 to rotate. The lead screw 3 can drive the pressing block 202 to slide along the sliding frame 2, so that the pressing block 202 can easily fit and press against the outside or inside of the bottom end of the flange ring, thereby fixing the flange ring at the center of the rotating gear disk 101. It can effectively fix flange rings of different sizes.

[0033] At this point, the welding position can be easily detected using the ultrasonic probe 4. The electric adjusting push rod 5 drives the fixed ring 501 to rise, which in turn drives the fixed block 504 to rise via the adjusting rod 503, thereby moving the electric lifting rod 403. Simultaneously, the electric lifting rod 403 can be activated to lower the ultrasonic probe 4 at the bottom, thus adjusting the detection position. Furthermore, the clamping plate 401 can be rotated around the threaded rod 402 to adjust the angle of the ultrasonic probe 4, allowing for different detection angles. The drive motor 103 can also drive the drive gear 102 to rotate, which in turn causes the rotating gear 101 and the connecting gear 301 to rotate, thereby causing the sliding frame 2 to rotate the flange workpiece at the top, thus achieving circumferential detection, which is very convenient.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
