Description

Technical Field

[0001] The utility model relates to the technical field of pipeline detection, in particular to a device for detecting the flatness of a flat pipe welding surface. Background Art

[0002] The water tank pipe is a flat tube, mostly made of aluminum or copper, with a rectangular cross-section. This flat tube is formed by bending and welding, that is, the aluminum sheet is folded into a rectangle through a bending mechanism, and then welded at the interface.

[0003] After welding, there will be welds on the welding surface of the rectangular tube, which need to be smoothed using a grinding device. In order to detect the grinding quality, the horizontality of the welding surface of the rectangular tube needs to be detected. Generally, the sensor is installed on the conveying path of the rectangular tube, and the flatness of the welding surface is judged by whether the rectangular tube interferes with the sensor's light beam. However, due to the different specifications of the rectangular tubes, the heights of their welding surfaces are also different. Therefore, it is necessary to adjust the height of the sensor's light beam transmitting end and the reflecting end. However, the transmitting end and the reflecting end are respectively connected to different brackets on both sides of the flat tube conveying path. After adjusting their heights, the relative positions of the transmitting end and the reflecting end need to be adjusted to ensure that the light beam of the transmitting end is accurately irradiated on the reflecting end. The operation is cumbersome, time-consuming and labor-intensive. Utility Model Content

[0004] The main purpose of the utility model is to provide a flat tube welding surface flatness detection device. When the two first screws rotate in the same direction, the height positions of the sensor body and the reflector can be adjusted synchronously, so that personnel do not need to calibrate the relative positions of the sensor body and the reflector after adjusting the heights, thereby reducing the amount of operation and improving efficiency.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A flat tube welding surface flatness detection device comprises a U-shaped seat and a detection sensor assembly, wherein adjustment assemblies are arranged on opposite sides of the U-shaped seat, wherein the adjustment assembly comprises a first screw rod vertically threadedly connected to the U-shaped seat, wherein a fixing plate is rotatably connected to the top of the first screw rod, and a connecting plate is fixed between two groups of fixing plates of the adjustment assemblies, wherein a sensor body is fixed on the fixing plate of one group of the adjustment assemblies, and a reflector is fixed on the fixing plate of the other group of the adjustment assemblies, and the sensor body and the reflector are arranged opposite to each other.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-3 As shown, a flat tube welding surface flatness detection device includes a U-shaped seat 1 and a detection sensor assembly 3. Adjustment assemblies 2 are arranged on opposite sides of the U-shaped seat 1. The adjustment assembly 2 includes a first screw 201 vertically threadedly connected to the U-shaped seat 1. The top of the first screw 201 is rotatably connected to a fixing plate 203. A connecting plate 5 is fixed between the fixing plates 203 of two groups of adjustment assemblies 2. A sensor body 301 is fixed on the fixing plate 203 of one group of adjustment assemblies 2, and a reflector 302 is fixed on the fixing plate 203 of the other group of adjustment assemblies 2. The sensor body 301 and the reflector 302 are arranged opposite to each other. A bearing 202 is fixed on the bottom of the fixing plate 203. The top of the first screw 201 is fixed in the rotating circle of the bearing 202.

[0023] In this embodiment, if Figure 1 and Figure 3 As shown, the flat tube 7 after welding is transported inside the U-shaped seat 1. At this time, since the two first screw rods 201 are respectively rotated to connect the two fixed plates 203, and the two fixed plates 203 are connected into a whole through the connecting plate 5, when the two first screw rods 201 rotate in the same direction, the heights of the two fixed plates 203 can be adjusted synchronously, and then the height positions of the sensor body 301 and the reflector 302 can be adjusted synchronously, so that there is no need for personnel to calibrate the relative positions of the two after adjusting the heights of the sensor body 301 and the reflector 302, thereby reducing the amount of operation and improving efficiency.

[0024] The sensor body 301 is a mirror reflection photoelectric sensor. After the positions of the sensor body 301 and the reflector 302 are confirmed, the sensor body 301 will emit a light beam when it is working. The horizontal height of the light beam is located at the top of the welding surface of the flat tube 7. When the horizontality of the welding surface of the flat tube 7 meets the requirements, the light beam will be irradiated onto the reflector 302, and will be reflected back to the sensor body 301 and received by the sensor body 301. When the horizontality of the welding surface of the flat tube 7 does not meet the requirements, it will block the light beam. If the light intensity received by the sensor body 301 is insufficient, the detection sensor component 3 will send a signal to the controller 8, and the controller 8 and the alarm 9 will work and sound an alarm to remind the staff. This is a prior art and will not be elaborated here.

[0025] The bottom of the U-shaped seat 1 is rotatably connected to a plurality of rotating rollers 6 for carrying the flat tube 7. Figure 1 and Figure 2 As shown, the bottom of the flat tube 7 contacts the rotating roller 6. When the flat tube 7 is being transported, since the rotating roller 6 can rotate itself, the resistance encountered by the flat tube 7 during movement can be reduced.

[0026] Among them, Figure 1 and Figure 2As shown, a plurality of limit assemblies 4 for limiting the flat tube 7 are arranged on opposite sides of the U-shaped seat 1, and the limit assemblies 4 include a second screw rod 401 threadedly connected to the side surface of the U-shaped seat 1, and a ball 402 is rollingly embedded in the end of the second screw rod 401 located in the U-shaped seat 1, and the second screw rod 401 is arranged horizontally. When the flat tube 7 is conveyed in the U-shaped seat 1, although the conveying mechanism on the production line will limit the conveying path of the flat tube 7, since this limit mechanism is located at both ends of the conveying path of the flat tube 7, and the entire conveying path is long, the flat tube 7 will be slightly tilted due to vibration during the conveying process, and it is impossible to always report a vertical state. Therefore, by rotating multiple second screw rods 401 and pressing the flat tube 7 from both sides with the ball 402, the flat tube 7 can be prevented from tilting, thereby improving the accuracy of the flat tube 7 welding surface horizontality detection, and the ball 402 itself can rotate, thereby reducing the resistance encountered by the flat tube 7 when it moves.

[0027] Working principle: fix the U-shaped seat 1 on the conveying path of the flat tube 7, and make the flat tube 7 be conveyed in the U-shaped seat 1. Next, when it is necessary to detect the flatness of the welding surface of the flat tube 7, the two first screws 201 are rotated in the same square according to the height of the welding surface of the flat tube 7, so as to synchronously adjust the height position of the sensor body 301 and the reflector 302 until the light beam emitted by the sensor body 301 is located at the top of the welding surface of the flat tube 7. At this time, if the horizontality of the welding surface of the flat tube 7 meets the requirements, the light beam will be irradiated to the reflector 302 and will be reflected back. The sensor body 301 is received by the sensor body 301, and when the horizontality of the welding surface of the flat tube 7 does not meet the requirements, it will block the light beam, and the light intensity received by the sensor body 301 is insufficient, then the detection sensor assembly 3 sends a signal to the controller 8, and the controller 8 controller 8 alarm 9 works and sounds an alarm to remind the staff, and during the transportation of the flat tube 7, multiple second screws 401 can be rotated so that the balls 402 can press against the flat tube 7 from both sides, thereby preventing the flat tube 7 from tilting, so as to improve the accuracy of the flat tube 7 welding surface horizontality detection.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
