Description

Technical Field

[0001] The utility model relates to the field of alloy surface defect detection, in particular to a device for detecting surface defects of aluminum alloy profiles. Background Art

[0002] Aluminum alloy is an alloy based on aluminum with a certain amount of other alloying elements added. It is one of the light metal materials. The strength of aluminum alloy is close to that of high-alloy steel, and its specific stiffness exceeds that of steel. It has good casting properties and plastic processing properties, good electrical and thermal conductivity, good corrosion resistance and weldability. It can be used as a structural material and is widely used in aerospace, aviation, transportation, construction, electromechanical, light chemical and daily necessities.

[0003] At present, there are various methods for detecting aluminum alloy surface defects, among which the most common and flexible method is still manual inspection. This method is not only relatively low-cost, but also can detect many surfaces that are difficult for machines to reach, or the surfaces of various special-shaped aluminum alloy profiles, showing its unique advantages.

[0004] However, manual inspection still has certain problems. For example, when faced with tiny bumps on the surface of aluminum alloy profiles, the inspection is difficult and requires workers to observe more carefully, which leads to a certain deviation in accuracy. At the same time, the manual inspection process is very time-consuming, and the increased working hours actually increase the cost in disguise. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a surface defect detection device for aluminum alloy profiles to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for detecting surface defects of aluminum alloy profiles, comprising a device body and a laser emitter, a fixed plate and a first blocking plate are fixedly installed on the outer wall of the device body, a detector is slidably installed in the device body, a laser emitter is fixedly installed in the fixed plate, the detector comprises a connecting rod, a roller and a second telescopic rod, the connecting rod is installed in the device body, a roller is rotatably installed on the bottom end of the connecting rod, and a second telescopic rod is fixedly installed on the top end of the connecting rod, a trigger is fixedly installed in the device body, and an alarm corresponding to the trigger is fixedly installed on the top end of the device body.

[0007] By adopting the above technical solution, when the device is placed on the surface of the aluminum alloy profile, push the device body. When the roller at the bottom of the detector touches the protrusion on the surface of the aluminum alloy profile, the detector will be pushed upward. At this time, the second telescopic rod of the detector will trigger the trigger, thereby triggering the alarm of the alarm, so as to tell the worker that there is a protrusion on the surface of the aluminum alloy profile here. And the second baffle will extend from the top of the device body to block the laser emitter triggered by the trigger, so that the worker can intuitively see where there is a protrusion on the surface of the aluminum alloy profile.

[0008] Further, the detector further includes a first telescopic rod and a spring. The bottom end of the first telescopic rod is fixedly installed at the top end of the connecting rod, and the top end of the first telescopic rod is fixedly installed on the inner wall of the device body. And a spring is sleeved on the outer wall of the first telescopic rod. One end of the spring is fixedly connected to the top end of the first telescopic rod, and the other end is fixedly connected to the inner wall of the device body.

[0009] By adopting the above technical solution, the first telescopic rod has a limiting effect on the spring, and when the detector encounters a protrusion on the surface of the aluminum alloy profile, the spring will be stressed and contracted. When leaving the protrusion, the spring will release force, so that the detector is reset.

[0010] Further, the detector further includes a second baffle. One end of the second baffle is fixedly installed at the top end of the connecting rod, and the other end penetrates through the top of the device body.

[0011] By adopting the above technical solution, when the detector encounters a protrusion on the surface of the aluminum alloy profile, the second baffle will extend from the top of the device body, thereby blocking the laser emitted by the laser emitter, so that the worker can intuitively see the position of the protrusion.

[0012] Further, multiple groups of detectors are installed in the device body.

[0013] By adopting the above technical solution, the detection range is further improved.

[0014] Further, both the alarm and the laser emitter are connected to the trigger.

[0015] By adopting the above technical solution, when the detector encounters a protrusion on the surface of the aluminum alloy profile, the alarm and the laser emitter will be triggered simultaneously.

[0016] Further, the installation position of the laser emitter on the fixed plate is on the same horizontal line as the top end of the device body, and the emission direction of the laser emitter is on the same straight line as the second baffle and the first baffle.

[0017] By adopting the above technical solution, when the laser emitter emits laser, even when encountering a tiny protrusion, it can be blocked by the second baffle.

[0018] Further, the trigger is fixedly installed on the inner wall of the device body, above the second telescopic rod, and the distance between the trigger and the second telescopic rod is 5 mm.

[0019] By adopting the above technical solution, micro protrusions larger than 5 mm can be detected by the detector, and this distance can be adjusted as needed.

[0020] Further, the cross-section of the connecting rod is designed in a T shape.

[0021] By adopting the above technical solution, there is enough space at the top of the connecting rod to connect the second baffle, the first telescopic rod and the second telescopic rod.

[0022] In summary, the main beneficial effects of the present utility model are as follows:

[0023] With the detector provided in the present utility model, when the device is placed on the surface of the aluminum alloy profile and the device body is pushed, when the roller at the bottom end of the detector touches the protrusion on the surface of the aluminum alloy profile, the detector will be pushed upward. At this time, the second telescopic rod of the detector will trigger the trigger, thus triggering the alarm of the alarm, telling the worker that there is a protrusion on the surface of the aluminum alloy profile here, and the second baffle will extend from the top end of the device body to block the laser emitter triggered by the trigger, enabling the worker to intuitively see where there is a protrusion on the surface of the aluminum alloy profile.

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0031] Next, according to the overall structure of the present utility model, its embodiments will be described.

[0032] An aluminum alloy profile surface defect detection device, as Figure 1 - Figure 5 shown, includes a device main body 1 and a laser emitter 3. A fixing plate 2 and a first blocking plate 201 are fixedly installed on the outer wall of the device main body 1. The laser emitted by the laser emitter 3 will be blocked by the first blocking plate 201. And a detector 4 is slidably installed in the device main body 1. The detector 4 is used to detect the surface defects of the aluminum alloy profile. The fixing plate 2 is fixedly installed with a laser emitter 3 for emitting laser to remind the worker of the location of the defect. The detector 4 includes a connecting rod 401, a roller 402 and a second telescopic rod 406. The connecting rod 401 is installed in the device main body 1. The connecting rod 401 is designed in a T shape. And a roller 402 is rotatably installed at the bottom end of the connecting rod 401. The roller 402 facilitates the sliding of the detector 4 on the surface of the aluminum alloy profile. And a second telescopic rod 406 is fixedly installed at the top end of the connecting rod 401 for triggering a trigger 5. A trigger 5 is fixedly installed in the device main body 1 for triggering an alarm 6. And an alarm 6 corresponding to the trigger 5 is fixedly installed at the top end of the device main body 1.

[0033] Please refer to Figure 2 - Figure 5 , the detector 4 further includes a first telescopic rod 403 and a spring 404. The bottom end of the first telescopic rod 403 is fixedly installed at the top end of the connecting rod 401. And the top end of the first telescopic rod 403 is fixedly installed with the inner wall of the device main body 1. And a spring 404 is sleeved on the outer wall of the first telescopic rod 403. One end of the spring 404 is fixedly connected to the top end of the first telescopic rod 403, and the other end is fixedly connected to the inner wall of the device main body 1. The first telescopic rod 403 plays a limiting effect on the spring 404. And when the detector 4 encounters a protrusion on the surface of the aluminum alloy profile, the spring 404 will be stressed and contract. When leaving the protrusion, the spring 404 will release force, causing the detector 4 to reset.

[0034] Please refer to Figure 2 - Figure 5 , the detector 4 further includes a second blocking plate 405. One end of the second blocking plate 405 is fixedly installed at the top end of the connecting rod 401, and the other end penetrates through the top of the device main body 1. When the detector 4 encounters a protrusion on the surface of the aluminum alloy profile, the second blocking plate 405 will extend out from the top of the device main body 1, thereby blocking the laser emitted by the laser emitter 3, so that the worker can intuitively see the position of the protrusion.

[0035] Please refer to Figure 1 - Figure 4 In the device main body 1, multiple groups of detectors 4 are installed, which further improves the detection range.

[0036] Please refer to Figure 2 - Figure 4 The alarm 6 and the laser emitter 3 are both connected to the trigger 5. When the detector 4 encounters a protrusion on the surface of the aluminum alloy profile, the alarm 6 and the laser emitter 3 will be triggered simultaneously.

[0037] Please refer to Figure 1 - Figure 4 The installation position of the laser emitter 3 on the fixed plate 2 is on the same horizontal line as the top end of the device main body 1, and the emission direction of the laser emitter 3 is on the same straight line as the second baffle 405 and the first baffle 201. When the laser emitter 3 emits laser, even if it encounters a tiny protrusion, it can be blocked by the second baffle 405.

[0038] Please refer to Figure 2 and Figure 4 The trigger 5 is fixedly installed on the inner wall of the device main body 1, and the trigger 5 is above the second telescopic rod 406, and the distance between the trigger 5 and the second telescopic rod 406 is 5 mm, so that tiny protrusions larger than 5 mm can be detected by the detector 4, and this distance can be adjusted as needed.

[0039] Please refer to Figure 2 - Figure 5 The cross-section of the connecting rod 401 is designed in a T shape, so that there is enough space at the top of the connecting rod 401 to connect the second baffle 405, the first telescopic rod 403 and the second telescopic rod 406.

[0040] The working principle of the present utility model is as follows: When using the device, place the device main body 1 on the surface of the aluminum alloy profile and push the device main body 1. Since multiple detectors 4 are slidably installed in the device main body 1, and rollers 402 are rotatably installed at the bottom ends of the detectors 4, when the device main body 1 is pushed and encounters a protrusion on the surface of the aluminum alloy profile, the protrusion block will lift the rollers 402. At this time, the entire detector 4 will be lifted. Since the top end of the connecting rod 401 of the detector 4 is fixedly installed with a second telescopic rod 406, and the trigger 5 fixedly installed in the device main body 1 is above the second telescopic rod 406, the top end of the second telescopic rod 406 will touch the trigger 5, thereby triggering the laser emitter 3 and the alarm 6 connected to the trigger 5. Since the top end of the connecting rod 401 is fixedly installed with a second baffle 405, and the second baffle 405 penetrates the top end of the device main body 1, and the emission directions of the second baffle 405 and the laser emitter 3 are on the same straight line, at this time, the second baffle 405 will extend out from the top end of the device main body 1 to block the laser of the laser emitter 3, enabling the worker to intuitively see the position of the protrusion when there is a protrusion on the surface of the aluminum alloy profile. Since the top end of the connecting rod 401 is fixedly installed with a first telescopic rod 403, and a spring 404 is sleeved outside the first telescopic rod 403, when the connecting rod 401 is lifted, the spring 404 will also be squeezed. When the device main body 1 leaves the protrusion position, the spring 404 will release the pressure, thereby resetting the detector 4 and making the rollers 402 at the bottom end of the detector 4 fit the surface of the aluminum alloy profile again.

The specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions, and variations without creative contributions to the embodiments according to needs, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
