Description

Technical Field

[0001] The present invention relates to the technical field of aluminum profile detection, and in particular to a compressive detection device for aluminum profiles. Background Art

[0002] Industrial aluminum profiles are alloy materials mainly composed of aluminum. Aluminum rods are melted and extruded to obtain aluminum materials with different cross-sectional shapes. However, due to different proportions of added alloys, the mechanical properties and application fields of the produced industrial aluminum profiles are also different. After the aluminum profiles are processed and produced, compressive detection equipment is required to detect the compressive properties of the aluminum profiles.

[0003] In the prior art, when detecting aluminum profiles, the pressure block that moves up and down is used to press on the aluminum profile, and the force sensor is used to sense the force during pressing, so as to realize the anti-pressing detection work of the aluminum profile.

[0004] However, in the actual detection process, the pressure block that moves up and down only impacts a certain position of the aluminum profile to achieve the detection effect. In this way, the detection work is relatively single and the detection accuracy needs to be improved. When it is necessary to perform anti-pressing detection on different positions of the aluminum profile, it is necessary to re-adjust the position of the aluminum profile, which is time-consuming and laborious and reduces the work efficiency.

[0030] Refer to Figures 1 - 7, an embodiment of the present invention discloses a compressive testing device for aluminum profiles, including a bottom plate 1 and a support plate 4. In the middle of the upper surface of the bottom plate 1, a plurality of support rods 2 are connected. The top ends of the support rods 2 are connected to the support plate 4. The support plate 4 is in the shape of an annular plate. On the left edge of the upper surface of the bottom plate 1, a fixing frame 5 is fastened by bolts. A detection structure is arranged on the fixing frame 5 through a moving and lifting structure, and a rotating feeding structure is arranged on the support plate 4; The moving and lifting structure includes vertical grooves 8 opened at the upper parts of both side surfaces of the fixing frame 5. Lifting blocks 7 are slidably arranged in the vertical grooves 8. On the left and right sides of the upper surface of the fixing frame 5, first electric telescopic rods 6 are installed respectively. The bottom ends of the output shafts of the first electric telescopic rods 6 are connected to the lifting blocks 7. A guide rail plate 9 is installed between the two lifting blocks 7. A moving sleeve 10 is movably sleeved on the guide rail plate 9. An installation frame 11 is arranged under the moving sleeve 10 through a moving structure. The detection structure is arranged at the bottom end of the installation frame 11. A driving structure is arranged between the moving sleeve 10 and the fixing frame 5;

[0031] The driving structure includes a first opening 3 opened in the middle of the upper surface of the fixing frame 5. A cross plate 13 is connected between the inner walls of both sides of the first opening 3. A plurality of first guiding grooves 15 are equidistantly opened on the front surface of the cross plate 13. A second guiding groove 16 is opened between two adjacent first guiding grooves 15 on the front surface of the cross plate 13. The second guiding groove 16 communicates with the first guiding groove 15. A first insertion groove 14 is opened at the upper groove wall of the rightmost first guiding groove 15. A first insertion rod 12 and a second insertion rod 17 are arranged on the installation frame 11 through a switching structure. The top end of the first insertion rod 12 is movably inserted into the first insertion groove 14. A plurality of third guiding grooves 19 are equidistantly opened on the rear surface of the cross plate 13. A fourth guiding groove 20 is opened between two adjacent third guiding grooves 19 on the rear side of the cross plate 13. The fourth guiding groove 20 communicates with the third guiding groove 19. A second insertion groove 18 is opened at the upper groove wall of the leftmost third guiding groove 19;

[0032] The switching structure includes an installation seat 21 installed on the moving sleeve 10. The installation seat 21 extends into the installation frame 11. A second electric telescopic rod 22 is installed at the middle of the lower surface of the installation seat 21. A end block 23 is installed at the bottom end of the output shaft of the second electric telescopic rod 22. A driving frame 24 is arranged on the end block 23. A through plate 25 passes through the installation frame 11 near the middle. A driving groove 26 is opened on the through plate 25. The driving frame 24 passes through the driving groove 26 movably;

[0033] The detection structure includes a detection rod 34 fixedly connected to the middle of the lower surface of the installation frame 11. A pressure block 35 is installed at the bottom end of the detection rod 34, and a pressure sensor 36 is arranged on the pressure block 35. A controller 37 is arranged at a position near the upper part of the left side surface of the fixed frame 5. The pressure sensor 36 is electrically connected to the controller 37. When detecting the aluminum profile, the first electric telescopic rod 6 is started to drive the lifting block 7, the guide rail plate 9, the installation frame 11 and the pressure block 35 to move downward as a whole. During the downward movement of the installation frame 11, the top end of the first insertion rod 12 is driven to slide from the first insertion groove 14 into the first guiding groove 15. By the extrusion of the end part of the first insertion rod 12 on the groove wall of the first guiding groove 15, the moving sleeve 10 is driven to move leftward on the guide rail plate 9, so as to drive the installation frame 11 and the pressure block 35 to move leftward as a whole. When the top end of the first insertion rod 12 slides into the vertical section of the first guiding groove 15, the moving sleeve 10 keeps its position unchanged on the guide rail plate 9. As the lifting block 7 continues to move downward, the pressure block 35 can be driven to press on the aluminum profile. The pressure sensor 36 senses the pressure generated during the pressing and is displayed on the display screen of the controller 37 to realize the detection of the anti-pressing performance of the aluminum profile. After detecting a certain position on the aluminum profile, the first electric telescopic rod 6 drives the lifting block 7 to move upward, so as to drive the top end of the first insertion rod 12 to move out of the vertical section of the first guiding groove 15. The first insertion rod 12 moves vertically upward and presses on the groove wall of the second guiding groove 16, so that the moving sleeve 10 continues to drive the pressure block 35 to move leftward on the guide rail plate 9. When the top end of the first insertion rod 12 slides to the uppermost position in the second guiding groove 16, at this time, the lifting block 7 moves to the highest position. Then the first electric telescopic rod 6 drives the lifting block 7 and the first insertion rod 12 to move downward. The downward moving first insertion rod 12 presses on the lower groove wall of the corresponding first guiding groove 15. As the first insertion rod 12 continues to move downward, the moving sleeve 10 continues to move leftward on the guide rail plate 9. In this way, when the lifting block 7 drives one end of the first insertion rod 12 to slide in the corresponding first guiding groove 15, the pressure block 35 can be driven to detect different positions on the aluminum profile, so as to improve the detection accuracy, and the operation is also more labor-saving and convenient. When the moving sleeve 10 moves to the leftmost side on the guide rail plate 9 and the lifting block 7 is at the lowest position, the second electric telescopic rod 22 can be started to drive the driving frame 24 to slide downward in the driving groove 26. By the extrusion of the driving frame 24 on the groove wall of the driving groove 26, the through plate 25 is pushed to move on the installation frame 11, so as to pull out the top end of the first insertion rod 12 from the first guiding groove 15 corresponding to the front surface of the cross plate 13. At this time, the driving frame 24 moves down by half of its height. Then the first electric telescopic rod 6 drives the lifting block 7 to move up to the highest position, and the second electric telescopic rod 22 drives the driving frame 24 to continue to move downward in the driving groove 26. By the extrusion of the driving frame 24 on the groove wall of the driving groove 26, the through plate 25 is continuously pushed to move on the installation frame 11, so as to drive the top end of the second insertion rod 17 to insert into the second insertion groove 18 on the back surface of the cross plate 13. In this way, as the lifting block 7 moves up and down,It can drive the pressure block 35 to move intermittently to the right, so as to detect the compressive resistance performance of each position on the next aluminum profile.

[0034] See Figures 4 - 7 , the moving structure includes a chute 33 opened at the lower part of the moving sleeve 10. A slider 32 is slidably arranged in the chute 33. The top end of the installation frame 11 is fixedly installed on the slider 32. A guiding structure is arranged between the slider 32 and the fixed frame 5;

[0035] The guiding structure includes a rotating shaft 31 rotatably connected to the middle of the lower surface of the slider 32. A spherical block 30 is arranged at the bottom end of the rotating shaft 31. A guide rail rod 27 passes through the spherical block 30 movably. The middle section of the guide rail rod 27 is arc-shaped. Guide blocks 28 are installed at both ends of the guide rail rod 27. Guide grooves 29 for the guide blocks 28 to slide are opened on both inner walls of the fixed frame 5. When the moving sleeve 10 moves back and forth on the guide rail plate 9, it can drive the installation frame 11 to move on the guide rail rod 27. In this way, the installation frame 11 drives the pressure block 35 to move on the guide rail rod 27 with an arc-shaped middle section, which can drive the pressure block 35 to detect different positions in the width direction of the aluminum profile, further improving the detection accuracy.

[0036] See Figures 1 - 3 , two second openings 38 are opened on the support plate 4. The two second openings 38 are distributed radially on the support plate 4. One of the second openings 38 is located at the position of the fixed frame 5. A material receiving frame 39 is installed on the bottom plate 1 at the position directly below the other second opening 38;

[0037] The rotary feeding structure includes a mounting disc 40 fixedly sleeved on the support rod 2. A motor 41 is installed in the middle of the upper surface of the mounting disc 40. A rotating block 42 is installed at the top end of the output shaft of the motor 41. A plurality of connecting rods 43 are connected to the side circumference of the rotating block 42 at equal angles. One end of each connecting rod 43 is fixedly connected to the inner wall of the feeding disc 44. The feeding disc 44 is arranged close to the upper surface of the support plate 4. A plurality of third openings 45 are opened at equal intervals in the circumferential direction of the feeding disc 44. A clamping structure is arranged in each third opening 45;

[0038] The clamping structure includes mounting blocks 46 arranged along the inner edge of the feeding tray 44 near the third opening 45. A third electric telescopic rod 47 is installed at the middle of one side of each mounting block 46 close to the axis of the feeding tray 44. An inner groove 50 is formed on the lower groove wall of the third opening 45. A fixing rod 51 is fixedly connected between the two end groove walls of the inner groove 50. Moving blocks 52 are movably sleeved on the fixing rod 51 near both ends. An extrusion rod 53 is connected above the moving block 52. Springs 54 are sleeved on both ends of the fixing rod 51, and the two ends of the springs 54 are respectively connected to the moving block 52 and the groove wall of the inner groove 50. A clamping strip 55 passing through the inner groove 50 is connected to the moving block 52. Clamping blocks 56 are arranged at positions near both ends of one side of the clamping strip 55. One end of the output shaft of the third electric telescopic rod 47 is connected to a moving plate 48. Two extrusion plates 49 are connected near the middle of the moving plate 48. The extrusion plates 49 are pressed against the extrusion rod 53. When the aluminum profile to be processed is placed in the third opening 45 on the feeding tray 44, the third electric telescopic rod 47 is started to drive the moving plate 48 and the extrusion plates 49 as a whole to move away from the axis of the feeding tray 44. Through the extrusion of the extrusion plates 49 on the extrusion rod 53, the two clamping strips 55 can be pushed to move towards each other, thereby driving the clamping blocks 56 to move towards the middle to clamp and fix the aluminum profile. In this way, when the motor 41 is started to drive the feeding tray 44 to rotate, the clamped aluminum profile can be conveyed to the fixing frame 5 for inspection. After the inspection, as the feeding tray 44 continues to rotate, the inspected aluminum profile can be conveyed to a position directly above the receiving frame 39. At this time, the third electric telescopic rod 47 is started to release the corresponding aluminum profile, so that the inspected aluminum profile can fall from the corresponding second opening 38 into the receiving frame 39, realizing the automatic blanking function and improving the inspection work efficiency.

[0039] The implementation principle of the compressive testing equipment for aluminum profiles in an embodiment of the present invention is as follows: First, place the aluminum profile to be tested into the third opening 45 on the feeding tray 44, and start the third electric telescopic rod 47 to drive the moving plate 48 and the extrusion plate 49 as a whole to move away from the axis of the feeding tray 44. Through the extrusion of the extrusion plate 49 on the extrusion rod 53, the two clamping strips 55 can be pushed to move towards each other, thereby driving the clamping block 56 to move towards the middle to clamp and fix the aluminum profile. Then, start the motor 41 to drive the feeding tray 44 to rotate, and convey the clamped aluminum profile to the fixed frame 5. Start the first electric telescopic rod 6 to drive the lifting block 7, the guide rail plate 9, the mounting frame 11, and the pressure block 35 as a whole to move downward. During the downward movement of the mounting frame 11, the top end of the first insertion rod 12 slides from the first insertion groove 14 into the first guiding groove 15. Through the extrusion of the end of the first insertion rod 12 on the groove wall of the first guiding groove 15, the moving sleeve 10 is driven to move leftward on the guide rail plate 9, thereby driving the mounting frame 11 and the pressure block 35 as a whole to move leftward. When the top end of the first insertion rod 12 slides into the vertical section of the first guiding groove 15, the moving sleeve 10 remains in place on the guide rail plate 9. As the lifting block 7 continues to move downward, the pressure block 35 can be driven to press on the aluminum profile. The pressure sensor 36 senses the pressure generated during stamping and displays it on the display screen of the controller 37 to achieve the detection of the anti-stamping performance of the aluminum profile. After detecting a certain position on the aluminum profile, the first electric telescopic rod 6 drives the lifting block 7 to move upward, driving the top end of the first insertion rod 12 to move out of the vertical section of the first guiding groove 15. The first insertion rod 12 moves vertically upward and presses on the groove wall of the second guiding groove 16, causing the moving sleeve 10 to continue to drive the pressure block 35 to move leftward on the guide rail plate 9. When the top end of the first insertion rod 12 slides to the uppermost position in the second guiding groove 16, at this time, the lifting block 7 moves to the highest position. Then, the first electric telescopic rod 6 drives the lifting block 7 and the first insertion rod 12 to move downward. The downward moving first insertion rod 12 presses on the lower groove wall of the corresponding first guiding groove 15. As the first insertion rod 12 continues to move downward, the moving sleeve 10 continues to move leftward on the guide rail plate 9. In this way, when the lifting block 7 drives one end of the first insertion rod 12 to slide in the corresponding first guiding groove 15, the pressure block 35 can be driven to detect different positions on the aluminum profile, thereby improving the detection accuracy and making the operation more labor-saving and convenient. When the moving sleeve 10 moves to the leftmost side on the guide rail plate 9 and the lifting block 7 is at the lowest position, the second electric telescopic rod 22 can be started to drive the driving frame 24 to slide downward in the driving groove 26. Through the extrusion of the driving frame 24 on the groove wall of the driving groove 26, the through plate 25 is pushed to move on the mounting frame 11, thereby pulling out the top end of the first insertion rod 12 from the first guiding groove 15 corresponding to the front of the cross plate 13. At this time, the driving frame 24 moves down by half of its height. Then, the first electric telescopic rod 6 drives the lifting block 7 to move up to the highest position, and the second electric telescopic rod 22 drives the driving frame 24 to continue to move down in the driving groove 26.Through the extrusion of the driving frame 24 against the groove wall of the driving groove 26, the through plate 25 is continuously pushed to move on the mounting frame 11, thereby driving the top end of the second insertion rod 17 to insert into the second insertion groove 18 on the back of the cross plate 13. Then, the motor 41 drives the feeding disk 44 to rotate, and fixes the next aluminum profile to be detected at the fixing frame 5. In this way, as the lifting block 7 continues to move up and down, driving the sliding of the top end of the second insertion rod 17 in the third guiding groove 19 and the fourth guiding groove 20, the pressure block 35 can be driven to move intermittently to the right, so as to detect the compressive resistance performance of each position on the next aluminum profile. Finally, the continuous rotation of the feeding disk 44 can convey the detected aluminum profile to the position directly above the receiving frame 39. At this time, the third electric telescopic rod 47 is started to release the corresponding aluminum profile, so that the detected aluminum profile can fall from the corresponding second opening 38 into the receiving frame 39, realizing the automatic blanking function and improving the detection work efficiency.

[0040] The above are all preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present invention shall be covered within the protection scope of the present invention.
