Description

Technical Field

[0001] The invention relates to the field of welding detection, in particular to a steel structure welding deformation detection device. Background Art

[0002] The metallographic structure of steel changes during the heating and cooling process. The different specific volumes of these structures will also cause welding stress and deformation. The shrinkage of the weld metal When the weld metal cools and changes from liquid to solid, its volume will shrink. Since the weld metal and the parent material are closely connected, the weld metal cannot shrink freely, which will cause deformation of the entire weldment and residual stress in the weld. These are the reasons why steel materials deform during welding.

[0003] However, since the welding deformation of steel materials varies in size, large deformation can be detected by naked eye, but small deformation cannot be well detected after welding, which can easily lead to the size of the final welded component not meeting the standard. Summary of the invention

[0005] To solve the above problems, the present invention adopts the following technical solutions:

[0007] As a further solution of the present invention: a pointer is installed above the infrared transmitter sleeve and on the outside of the rotating rod, an arc-shaped dial is provided on the upper surface of the signal generating mechanism below the pointer, a driving gear is installed at the lower end of the infrared transmitter sleeve, a driven gear is provided on one side of the driving gear, and a rotating shaft is installed between the driving gear, the driven gear and the signal generating mechanism.

[0008] As a further solution of the present invention: the clamping mechanism includes a first clamp and a second clamp, a scale is connected between the first clamp and the second clamp, anti-drop blocks are installed at both ends of the scale, and storage bins for storing the scale are opened inside the first clamp and the second clamp.

[0009] As a further solution of the present invention: a receiving cable is connected between the signal display and the infrared receiver, a limiting slide groove is provided inside the signal receiving mechanism, and a spring fixedly connected to the welding plate clamping block is installed inside the limiting slide groove.

[0010] As a further solution of the present invention: the first clamp and the second clamp are both installed with reflectors on one side close to the first welding plate and the second welding plate, the upper surfaces of the first clamp and the second clamp are both installed with fastening screws, and the lower ends of the fastening screws are installed with clamping gaskets.

[0011] As a further solution of the present invention: the welding plate clamping block is slidably connected to the signal receiving mechanism through the movable perforation, the signal generating mechanism is movably connected to the second welding plate, and the welding position of the first welding plate and the second welding plate is located between the signal receiving mechanism and the signal generating mechanism.

[0012] As a further solution of the present invention: the driving gear is meshed and rotationally connected with the driven gear, and the pointer is movably connected with the signal generating mechanism.

[0013] As a further solution of the present invention: the scale is movably connected to the first clamp and the second clamp, and the first clamp and the second clamp are components with the same outer dimensions.

[0014] As a further solution of the present invention: the spring is elastically connected to the welding plate clamping block, and a guide slider is installed on one side of the welding plate clamping block located inside the limiting sliding groove.

[0015] As a further solution of the present invention: the fastening screw is meshed and rotatably connected with the first clamp and the second clamp.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The infrared transmitter emits infrared light toward the position of the clamping mechanism. After the infrared signal is transmitted to the reflector position, the infrared light can be reflected in different directions on the reflector according to different incident angles. The infrared light is then received by the infrared receiver arranged on the signal receiving mechanism. When the welding point between the first welding plate and the second welding plate is deformed, the transmission of the infrared light will be blocked. When the infrared receiver cannot receive the infrared light, the flatness of the welding position can be judged according to the display on the signal display.

[0018] 2. The welding plate clamping block can adjust its position on one side of the signal generating mechanism under the action of the movable perforation and the limiting slide groove, and can be installed with welding plates of different sizes. At the same time, the spring ensures that the welding plate clamping block is always clamped on the upper surface of the welding plate. Therefore, when the signal cannot be received, the welding position of the corresponding position is uneven.

[0019] 3. When torque is applied to the rotating rod, the driving gear and the driven gear will mesh and rotate through the rotating shaft to adjust the rotation angle as a whole. At the same time, the incident angle of the light is determined based on the angle reading of the pointer on the arc-shaped dial to determine the overall direction of the infrared transmitter sleeve and the infrared transmitter. Therefore, the light is controlled to detect different positions of the weld, thereby completing the welding detection of the entire welding equipment.

[0020] 4. The scale as a whole can move freely in the storage compartment inside the first clamp and the second clamp, so as to control the installation and clamping positions of the first clamp and the second clamp on the first welding plate and the second welding plate respectively, and control the distance between the two reflectors, so as to adjust the reflection angle of the infrared light conveniently.

The clamping mechanism 3 includes a first clamp 301 and a second clamp 302. The first clamp 301 and the second clamp 302 are both installed with a reflector 303 on the side close to the first welding plate 4 and the second welding plate 5. The infrared transmitter 206 arranged inside the signal generating mechanism 2 emits infrared light toward the position of the clamping mechanism 3. After the infrared signal is transmitted to the position of the reflector 303, the infrared light can be reflected in different directions on the reflector 303 according to different incident angles, and then the infrared light is received by the infrared receiver 107 arranged on the signal receiving mechanism 1.

The pointer 202 is provided at the upper surface of the signal generating mechanism 2. 203 is movably connected with the signal generating mechanism 2. When torque is applied to the rotating rod 201, the driving gear 208 and the driven gear 209 will be meshed and rotated through the rotating shaft 210 to adjust the rotation angle as a whole. At the same time, according to the angle reading of the pointer 203 on the arc-shaped dial 202, the overall direction of the infrared transmitter sleeve 207 and the infrared transmitter 206 is adjusted to determine the incident angle of the light, thereby controlling the light to detect different positions of the weld, thereby completing the welding detection of the entire welding equipment.

[0034] like Figure 1-3As shown, a scale 305 is connected between the first clamp 301 and the second clamp 302, and anti-dropping blocks 308 are installed at both ends of the scale 305. The first clamp 301 and the second clamp 302 are provided with storage bins 307 for storing the scale 305. The scale 305 is movably connected to the first clamp 301 and the second clamp 302.

[0035] The working principle of the present invention is as follows: when in use, the first clamp 301 and the second clamp 302 inside the clamping mechanism 3 are first respectively arranged on one side of the first welding plate 4 and the second welding plate 5, and the clamping of the clamping gasket 306 is adjusted by controlling the rotation of the fastening screw 304 to control the clamping effect of the clamping mechanism 3 on the first welding plate 4 and the second welding plate 5 as a whole. Then, the signal receiving mechanism 1 and the signal generating mechanism 2 are respectively installed on the other side of the first welding plate 4 and the second welding plate 5. After the connection between the first welding plate 4 and the second welding plate 5 is welded, the control is used to apply a torque to the rotating rod 201, so that the driving gear 208 and the driven gear 209 are meshed and rotated through the rotating shaft 210 to adjust the rotation angle as a whole, and at the same time, according to the pointer 203 on the arc dial 2 02, to adjust the overall direction of the infrared transmitter sleeve 207 and the infrared transmitter 206 to determine the incident angle of the light, thereby controlling the light to detect different positions of the weld. After the infrared signal is transmitted to the position of the reflector 303, the infrared light can be reflected in different directions on the reflector 303 according to different incident angles, and then the infrared light is received by the infrared receiver 107 arranged on the signal receiving mechanism 1. When the welding point of the first welding plate 4 and the second welding plate 5 is deformed, the transmission of the infrared light will be blocked. When the infrared receiver 107 cannot receive the infrared light, the flatness of the welding position can be judged according to the display on the signal display 101, thereby completing the welding detection of the entire welding equipment.
