Description

Technical Field

[0001] This invention relates to the field of aluminum parts inspection devices, and more particularly to a device for simultaneous detection of internal and external defects in aluminum parts of various specifications. Background Technology

[0002] In the field of aluminum parts manufacturing and processing, internal and external defect detection is a key link to ensure product quality and safety of use. It is necessary to check external defects such as surface scratches and dents, as well as hidden problems such as internal pores and cracks.

[0003] Traditional aluminum part inspection devices are mostly designed for a single specification, resulting in poor adaptability. For aluminum parts of different sizes and shapes, it is necessary to change special fixtures or adjust the inspection mechanism, which is cumbersome and time-consuming, seriously affecting the inspection efficiency. Moreover, the clamping mechanism of existing inspection devices is mostly rigid and fixed, making it difficult to accurately control the clamping force, which can easily cause secondary damage to the surface of aluminum parts, especially for thin-walled and irregularly shaped aluminum parts, where the risk of damage is even higher. In addition, dust, debris and other impurities generated during the production process are easily left on the surface of aluminum parts. Traditional inspection devices lack effective pre-treatment cleaning functions, and impurities can easily cover defective parts, leading to misjudgment. At the same time, there is no centralized dust collection mechanism generated during the inspection process, which not only pollutes the working environment but may also affect the service life of the inspection equipment.

[0010] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0011] Reference Figure 1-14An embodiment of the present invention provides a device for simultaneous detection of internal and external defects of aluminum parts with multiple specifications, comprising a conveyor 1, a loading assembly 2 fixedly connected to the outer side of the middle part of the conveyor 1, a gripping assembly 3 fixedly connected to the middle of the inner top wall of the loading assembly 2, a scanning detection assembly 4 fixedly connected to the outer side of the upper part of the loading assembly 2, a blowing assembly 5 fixedly connected to the front side of the loading assembly 2, and a dust collection assembly 6 fixedly connected to the rear side of the lower part of the loading assembly 2. The loading assembly 2 includes a main board 21 fixedly connected to the upper rear side of the conveyor 1, a secondary board 22 fixedly connected to the upper front side of the conveyor 1, and a top plate 23 fixedly connected to the upper sides of the main board 21 and the secondary board 22. The lower center of the top plate 23 has a mounting groove 24. The lower part of the main board 21 has multiple dust outlets 27 evenly distributed. The front center of the secondary board 22 has a through window 26. The upper sides of the main board 21 and the secondary board 22 are both provided with limit grooves 25.

[0012] The gripper assembly 3 includes a motor 31 fixedly connected to the inner wall of the mounting slot 24, a worm gear 32 fixedly connected to the output end of the motor 31, and a strip 33 fixedly connected to the same side of the upper section of the main plate 21 and the sub-plate 22. Four fixing plates 34 are evenly fixedly connected to the lower side of the middle of the strip 33. A worm wheel 35 is rotatably connected to the upper side of the fixing plate 34. A fixing strip 36 is fixedly connected to the middle of the side of the worm wheel 35 away from the fixing plate 34. An adapter strip 37 is rotatably connected to the end of the fixing strip 36 away from the worm wheel 35.

[0013] The worm gear 32 is rotatably connected to the middle of the strip 33. The worm gear 32 is set in the middle of the four fixed plates 34. The worm gear 32 and the four worm wheels 35 are all meshed with each other. The lower part of the fixed plate 34 is rotatably connected to the side of the corresponding worm wheel 35. The end of the rotating bar 38 away from the fixed plate 34 is rotatably connected to the middle of the corresponding adapter bar 37. The end of the rotating bar 38 near the fixed plate 34 away from the fixed bar 36 is fixedly connected to the shovel block 39. After the multi-specification adaptive clamping aluminum parts are transferred to the detection area, the motor 31 starts to drive the worm gear 32 to rotate. The worm gear 32 meshes with the four worm wheels 35, driving the worm wheels 35 to rotate synchronously. The worm wheels 35 pull the adapter bar 37 through the fixed bar 36, thereby driving the rotating bar 38 to rotate around the fixed plate 34 as the fulcrum. The shovel blocks 39 at the ends of the four rotating bars 38 converge towards the center to achieve stable clamping of aluminum parts of different sizes and shapes, and to prevent the aluminum parts from shifting during detection.

[0014] The scanning and detection assembly 4 includes a reel 41 fixedly connected to the outer wall of the upper section of the worm gear 32, and two fixing plates 42 respectively fixedly connected between the left and right ends of the upper part of the main plate 21 and the sub-plate 22. Detection elements 43 are slidably connected between the left and right ends of the two limiting slide grooves 25. The middle part of the side of the two detection elements 43 near the reel 41 is connected to the outer wall of the middle of the reel 41 on both sides away from the middle by a connecting rope 44. The middle part of the side of the two detection elements 43 away from the reel 41 is connected to the middle part of the side of the two fixing plates 42 near the reel 41 by a tension spring 45. When the worm gear 32 rotates, the reel 41 on the upper outer wall rotates synchronously. The two detection elements 43 are pulled along the limiting slide grooves 25 towards the middle by the two connecting ropes 44. The tension springs 45 are stretched and stored. During the movement of the detection elements 43, the inner and outer parts of the aluminum parts are scanned synchronously to accurately identify surface scratches, dents and internal cracks, pores and other defects.

[0015] The air blowing assembly 5 includes a fixed frame 51 fixedly connected to the inner wall of the window 26, a fixed connecting frame 52 fixedly connected to the side of the fixed frame 51 away from the main board 21, and a fixed connecting rod 513 fixedly connected to the side of the rotating shaft at one end of the transmission machine 1 near the sub-plate 22. An air outlet mesh 53 is fixedly connected to the inner wall of the fixed frame 51 on the side near the main board 21, and an air filter mesh 54 is fixedly connected to the inner wall of the fixed connecting frame 52 on the side away from the main board 21.

[0016] A pulley 514 is fixedly connected to the end of the fixed rod 513 away from the conveyor 1. A fixed frame 56 is fixedly connected to the inner wall of the fixed frame 52 away from the fixed frame 51. A pulley 57 is rotatably connected to the middle of the left end of the fixed frame 56 away from the air filter 54. A pulley 58 is rotatably connected to the middle of the right end of the fixed frame 56 away from the air filter 54. A pulley 59 is fixedly connected to the middle of the side of the pulley 58 away from the fixed frame 56. A fan 511 is fixedly connected to the middle of the side of the pulley 57 away from the fixed frame 56. A fan 512 is fixedly connected to the middle of the side of the pulley 59 away from the pulley 58.

[0017] The outer wall of pulley four 57 is connected to the outer wall of pulley three 59 by synchronous belt two 510, and the outer wall of pulley one 514 is connected to the outer wall of pulley two 58 by synchronous belt one 515.

[0018] Two through holes 55 are provided on one side of the fixed frame 52 near the fixed rod 513. The two middle sections of the timing belt 515 are respectively set in the middle of the two through holes 55. When the automatic dust removal conveyor 1 of the blowing assembly is running, the rotating shaft at one end drives the fixed rod 513 and pulley 514 to rotate. The timing belt 515 drives pulley 58 to rotate. Pulley 58 is linked with pulley 3 59, and then drives pulley 4 57 to rotate through timing belt 510, so that fan 1 511 and fan 2 512 start synchronously. After the airflow is filtered by the air filter 54, it is blown onto the aluminum parts on the conveyor 1 through the air outlet 53, blowing away the surface dust and debris to avoid impurities interfering with the test results.

[0019] The dust collection assembly 6 includes a dust collection box 61 fixedly connected to the lower rear side of the main board 21 and a box cover 63 hinged to the upper front inner wall of the dust collection box 61. A dust collection port 62 is provided through the upper front side of the dust collection box 61. The position of the dust collection port 62 corresponds to the position of multiple dust outlets 27. After the test is completed, the motor 31 rotates in the reverse direction, the roller 41 releases the connecting rope 44, and the tension spring 45 rebounds to drive the test piece 43 to reset, waiting for the next test. The dust blown away by the dust-cleaning assembly 5 and the debris generated during the test are collected and fall into the dust collection port 62 through the multiple dust outlets 27 at the lower part of the main board 21, and finally gather in the dust collection box 61. The box cover 63 of the dust collection box 61 can be opened and closed easily, which is convenient for regular dust cleaning.

[0020] Working Principle: This device achieves integrated operation of aluminum part cleaning, clamping, synchronous detection, and dust collection through the coordinated linkage of a conveyor, blowing assembly, gripping assembly, scanning and detection assembly, and dust collection assembly. The core of the operation revolves around power linkage and multi-process coordination. First, the equipment can achieve power transmission and cleaning clamping linkage. When the automatic dust removal conveyor 1 of the blowing assembly is running, its rotating shaft at one end drives the fixed rod 513 and pulley 514 to rotate. This drives pulley 58 to rotate via synchronous belt 515, which in turn drives pulley 59 to rotate via synchronous belt 515. Fan 510 drives pulley 57 to rotate, causing fan 511 and fan 512 to start synchronously. After being filtered by air filter screen 54, the airflow is blown onto the aluminum parts on the conveyor 1 through air outlet screen 53, blowing away surface dust and debris to avoid impurities interfering with the test results. After the multi-specification adaptive clamping aluminum parts are conveyed to the test area, motor 31 starts to drive worm gear 32 to rotate. Worm gear 32 meshes with four worm wheels 35, driving the worm wheels 35 to rotate synchronously. The worm wheels 35 pull the adapter bar 37 through the fixed connecting bar 36, thereby driving the rotating bar 38 to rotate around the fixed connecting plate 34 as the fulcrum. The four rotating bars 38 have their end shovels 39 converging towards the center, achieving a stable clamping of aluminum parts of different sizes and shapes, preventing displacement during inspection. Secondly, this equipment can also achieve simultaneous inspection and dust collection. When the worm gear 32 rotates, the upper outer wall of the worm gear 41 rotates synchronously, pulling two inspection pieces 43 along the limiting slide groove 25 towards the center via two connecting ropes 44. The tension spring 45 is stretched and stores force. During the movement of the inspection pieces 43, the internal and external surfaces of the aluminum parts are scanned simultaneously, accurately identifying surface scratches, dents, and internal cracks. After detecting defects such as cracks and pores, the motor 31 rotates in reverse, the reel 41 releases the connecting rope 44, and the tension spring 45 rebounds to reset the test piece 43, ready for the next test. The dust blown away by the dust collection and cleaning component 5 and the debris generated during the test fall into the dust collection port 62 through multiple dust outlets 27 at the bottom of the main board 21, and finally gather in the dust collection box 61. The cover 63 of the dust collection box 61 can be opened and closed easily, which facilitates regular dust cleaning, keeps the working environment clean, and avoids dust affecting the service life of the equipment, thus achieving synergy between testing and environmental protection.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
