Description

Technical Field

[0001] This utility model belongs to the field of bevel detection technology, specifically relating to a bevel angle detection device. Background Technology

[0002] A bevel is a groove of a specific geometric shape machined and assembled into the part of a workpiece to be welded. Beveling is primarily for ensuring weldability and is typically a surface profile machined using machining methods. For less demanding requirements, it can also be achieved through gas cutting. The bevel angle refers to the machining performed on the workpiece at the point to be welded before welding to ensure weld quality. This can be done through gas cutting or machining, and is generally an inclined surface, sometimes a curved surface. The bevel angle is a crucial welding process factor affecting weld formation, weld dilution rate, and the shape of the fusion zone. It even affects the stability of the welding arc. The bevel angle is a mandatory inspection item during the factory inspection of workpieces.

[0003] Existing bevel angle detection devices are not easy to fix in place, requiring manual maintenance to keep the device stable. This low stability affects the accuracy of angle detection, and the detection method is complex and inconvenient for operators, thus affecting detection efficiency. Utility Model Content

[0011] Preferably, the lower end of the angle plate is provided with a rotating groove, and the rotating groove and the pointer are rotatably connected.

[0012] Preferably, the pointer is rotatably connected to the angle plate via a connecting rod, and the torsion spring and the rotating groove are fixedly connected.

[0013] Compared with the prior art, this utility model provides a bevel angle detection device, which has the following features:

[0014] Beneficial effects:

[0015] 1. This utility model, by setting up an electric telescopic rod and a stop plate, uses a controller to control the electric telescopic rod to push the stop plate to move inward toward the inside of the pipe, thereby pressing against the pipe and ensuring the stability of the support column relative to the pipe. The anti-slip pad contacts the inside of the pipe, preventing the stop plate from sliding during the testing process and thus affecting the testing process. It eliminates the need for manual maintenance of the testing device and improves the accuracy of the testing process.

[0016] 2. This utility model, by setting a rotating component and a pointer, allows the detection device to determine its position. One side of the pointer contacts the bevel, squeezing one end of the pointer. Simultaneously, the connecting rod and torsion spring drive the pointer to rotate. The laser emitter inside the pointer emits light from the other end of the pointer, pointing towards the marking plate. The angle of the bevel is determined by observing the position of the light and the scale line. The measurement method is simple and easy for inspectors to use. Furthermore, by holding the handle and rotating the rotating component, the toothed column and toothed groove are engaged, which can drive the angle plate and pointer to rotate, thus facilitating angle detection at different positions of the bevel. The detection range is more comprehensive, and the detection efficiency is higher.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a scientific and reasonable structure, is safe and convenient to use, and provides great help to people. Attached Figure Description

The groove 15 and the angle plate 14 are equipped with a pointer 19. A torsion spring 21 is fixedly connected to one side of the pointer 19. A laser emitter 22 is fixedly connected to the upper end of the pointer 19. One side of the pointer 19 contacts the bevel 2, which squeezes one end of the pointer 19. At the same time, the connecting rod 20 and the torsion spring 21 drive the pointer 19 to rotate. The laser emitter 22 inside the pointer 19 emits light from the other end of the pointer 19, pointing to the marking plate 16. The angle of the bevel 2 is determined by observing the position of the light and the scale line 17. The measurement method is simple and easy for the testing personnel to use.

[0028] In this invention, preferably, an anti-slip pad 6 is fixedly connected to one side of the abutment 5 to prevent the abutment 5 from sliding during the testing process, thereby affecting the testing process.

[0029] In this utility model, preferably, one end of the support column 3 is fixedly connected to a limiting plate 7, and one side of the limiting plate 7 is fixedly connected to a controller 8.

[0030] In this utility model, preferably, a handle 12 is fixedly connected to one side of the rotating component 11.

[0031] In this utility model, preferably, one end of the rotating member 11 is fixedly connected to a toothed column 13, and the toothed column 13 and the toothed groove 10 are meshed. By holding the handle 12 and rotating the rotating member 11, the toothed column 13 and the toothed groove 10 are meshed, which can drive the angle plate 14 and the pointer 19 and other structures to rotate, thereby facilitating the angle detection of different positions of the bevel 2, with a more comprehensive detection range and higher detection efficiency.

[0032] In this utility model, preferably, an indicator plate 16 is fixedly connected to one side of the inside of the angle groove 15, and a scale line 17 is provided on one side of the indicator plate 16.

[0035] The working principle and usage process of this utility model are as follows: First, determine the position of the detection device. Then, control the electric telescopic rod 4 via the controller 8 to push the abutment 5 towards the inside of the pipe 1, pressing against the pipe 1 to ensure the stability of the support column 3 relative to the pipe 1. Simultaneously, the anti-slip pad 6 contacts the inside of the pipe 1 to prevent the abutment 5 from sliding during the detection process, thus avoiding any impact on the detection process. This eliminates the need for manual maintenance of the detection device's stability, improving the accuracy of the detection process. After the position is determined, one side of the pointer 19 contacts the bevel 2, squeezing one end of the pointer 19. Simultaneously, the connecting rod 20 and... The torsion spring 21 drives the pointer 19 to rotate. The laser emitter 22 inside the pointer 19 emits light from the other end of the pointer 19, pointing to the marker plate 16. The angle of the bevel 2 is determined by observing the position of the light and the scale line 17. The measurement method is simple and easy for inspectors to use. When it is necessary to inspect different positions of the bevel 2, the handle 12 is held and the rotating part 11 is rotated to make the toothed column 13 mesh with the toothed groove 10, which can drive the angle plate 14 and the pointer 19 to rotate, thus facilitating the angle inspection of different positions of the bevel 2. The inspection range is more comprehensive and the inspection efficiency is higher.
