DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0032] Reference Figure 1-Figure 8, a device for full-size automatic inspection of ceramic cores, including an inspection table 1 and a three-dimensional scanner 2. The three-dimensional scanner 2 adopts existing mature technology, and the specific model is Free / Scan / UE / Pro. It also includes: a rotating ring 3 rotating on the top of the inspection table 1, and a power unit for driving the rotating ring 3 to rotate is arranged in the inspection table 1. The power unit is used to drive the rotating ring 3 and the three-dimensional scanner 2 to perform annular inspection on the ceramic core, wherein a lifting part for pushing the three-dimensional scanner 2 to reciprocate is arranged on the rotating ring 3, and the lifting part is used to control the three-dimensional scanner 2 to perform comprehensive inspection on the vertical upper part of the ceramic core; a mounting plate 4 fixedly connected to the top of the inspection table 1, and a clamping part for fixing the ceramic core is arranged on the top of the mounting plate 4.

[0033] Reference Figure 1-Figure 4 , Figure 6 and Figure 8 , wherein the power unit includes a driving motor 5, which is fixed in the detection table 1, and a rotating toothed disc 51 is fixedly connected to the bottom side wall of the rotating ring 3, and a single-tooth gear 52 is fixedly connected to the top of the output shaft of the driving motor 5, and the single-tooth gear 52 is meshed with the rotating toothed disc 51; the lifting unit includes a lifting cylinder 6, which is fixed to the top of the rotating ring 3, and a lifting plate 61 is slidably connected in the lifting cylinder 6, and a mounting rod 62 is fixedly connected to the top of the lifting plate 61, and one end of the mounting rod 62 away from the lifting plate 61 is fixedly connected to the mounting seat 63, and the three-dimensional scanner 2 is fixed on the side wall of the mounting seat 63, and a strong magnetic plate 64 is fixedly connected to the top of the single-tooth gear 52, and a piston groove 31 is opened in the rotating ring 3, and a piston plate 311 is slidably connected in the piston groove 31, and the piston plate 311 and the strong magnetic plate 64 are magnetically repelled from each other on the side close to each other.

[0034] By setting the above structure, the driving motor 5 is turned on, and through the meshing relationship between the single-tooth gear 52 and the rotating toothed disc 51, when the single-tooth gear 52 rotates one circle, the rotating toothed disc 51 will rotate one tooth distance, thereby driving the rotating ring 3 to rotate continuously, and when the single-tooth gear 52 rotates, the piston plate 311 and the strong magnetic plate 64 are used to repel each other, so that the piston plate 311 is pushed upward, thereby compressing the gas in the piston groove 31, and part of the gas pushes the lifting plate 61 upward, so that the mounting rod 62 moves up with the three-dimensional scanner 2. When it reaches the upper limit ring 66, the piston plate 311 and the strong magnetic plate 64 are separated from each other, and the lifting plate 61 will move downward under the action of gravity, thereby realizing a comprehensive detection of the ceramic core in the vertical direction at a single angle. As the rotating ring 3 rotates, the three-dimensional scanner 2 will continuously switch angles to complete a comprehensive detection of the ceramic core, effectively improving the detection accuracy and efficiency. Finally, the three-dimensional scanner 2 will transmit all measurement data to the three-dimensional simulation terminal to form a three-dimensional model, thereby obtaining all dimensional information of the ceramic core.

[0035] In addition, the repulsive force between the piston plate 311 and the strong magnetic plate 64 is greater than the sum of the thrust required for the lifting plate 61 to move upward and the gravity of the piston plate 311; this ensures that when the piston plate 311 and the strong magnetic plate 64 repel each other, the lifting plate 61 can be pushed up smoothly.

[0036] Reference Figure 3 , Figure 4 and Figure 6 , wherein, dust suction pipes 631 are fixedly connected on both sides of the mounting seat 63, and the input ends of the dust suction pipes 631 on both sides are inclined toward the scanning end of the three-dimensional scanner 2, and an air suction groove 621 is opened in the mounting rod 62, the input end of the air suction groove 621 is connected to the output end of the dust suction pipe 631, the output end of the air suction groove 621 is connected to the inner cavity of the lifting cylinder 6, and a one-way valve is arranged in the air suction groove 621; a dust collecting box 65 is plugged and fixed at the bottom of the mounting seat 63, the dust collecting box 65 is connected to the inner cavity of the air suction groove 621, and a dust filter cotton net 651 is fixedly connected in the air suction groove 621.

[0037] It should be noted that the one-way valve in the air suction groove 621 can only allow the external airflow to be supplemented into the lifting cylinder 6.

[0038] Through the arrangement of the above-mentioned structure, when the lifting plate 61 moves down and resets, suction will be generated in the upper cavity of the lifting cylinder 6. At this time, the one-way valve in the suction groove 621 will be opened, so that the external airflow enters the lifting cylinder 6 along the dust suction pipe 631 and the suction groove 621, so as to supplement the blowing airflow. Secondly, it can speed up the gas flow rate at the scanning end of the three-dimensional scanner 2, thereby sucking away the dust attached thereto, ensuring the cleanliness of the scanning end of the three-dimensional scanner 2 and improving the final detection accuracy; and after the airflow enters the suction groove 621, it will be filtered through the dust filter cotton net 651, effectively ensuring the cleanliness of the subsequent blowing airflow and improving the cleaning effect. The filtered dust will eventually fall into the dust collecting box 65 under the action of gravity, so the dust collecting box 65 can be cleaned regularly.

[0039] Reference Figure 1-Figure 3 and Figure 7 The clamping part includes a clamping box 7, a clamping plate 71 is slidably connected inside the clamping box 7, a clamping spring 72 is fixedly connected between the top of the clamping plate 71 and the clamping box 7, a pull rod 73 is fixedly connected to the top of the clamping plate 71, the top of the pull rod 73 passes through the top of the clamping box 7, and the clamping spring 72 is sleeved on the outside of the pull rod 73, the center bottom of the clamping plate 71 and the center top of the testing platform 1 are fixedly connected with a silicone anti-wear pad 8, and an alignment mark 81 is provided in the center of the silicone anti-wear pad 8 on the testing platform 1.

[0040] Through the arrangement of the above structure, when in use, first pull the pull rod 73 upward to move the clamping plate 71 into the clamping box 7, then place the ceramic core to be tested at the center of the alignment mark 81 of the test table 1, and then slowly release the pull rod 73. Under the rebound action of the clamping spring 72, the clamping plate 71 fits with the top of the ceramic core, thereby utilizing the rebound force of the clamping spring 72 to fix the ceramic core, facilitate operation, and improve detection efficiency.

[0041] Reference Figure 4-Figure 6 Among them, the upper and lower parts of the inner cavity of the lifting cylinder 6 are fixedly connected with limit rings 66, and the distance between the two sets of limit rings 66 is equal to the distance from the bottom of the clamping plate 71 to the center of the detection platform 1. In this way, the moving range of the lifting plate 61 can be limited to ensure that it can move along the side wall height of the ceramic core, thereby improving the detection effect.

[0042] Reference Figure 3 , Figure 4 and Figure 7 , wherein an air guide ring 74 is fixedly connected to the mounting plate 4, the side wall of the rotating ring 3 is inserted into the air guide ring 74 and slidably connected thereto, an air blowing groove 41 is provided in the mounting plate 4, and the two ends of the air blowing groove 41 are respectively connected to the inner cavity of the clamping box 7 and the air guide ring 74, an air guide pipe 75 is fixed and connected to the upper part of the side wall of the lifting cylinder 6, the other end of the air guide pipe 75 passes through the rotating ring 3 and is connected to the inner cavity of the air guide ring 74, and a one-way valve is arranged in the air guide pipe 75, and air blowing holes 711 are provided at equal intervals on the outer periphery of the bottom of the clamping plate 71, and the output end of the air blowing hole 711 is inclined toward the center of the detection platform 1.

[0043] It should be noted that the one-way valve in the air guide tube 75 can only allow the airflow in the lifting cylinder 6 to enter the clamping box 7.

[0044] Through the arrangement of the above structure, when the lifting plate 61 moves upward along the lifting cylinder 6, the gas in the lifting cylinder 6 will be squeezed and the one-way valve in the air guide pipe 75 will be opened, so that this part of the gas will enter the clamping box 7 along the air guide pipe 75, the rotating ring 3 and the blowing groove 41. At this time, the air flow will pass downward through the blowing hole 711 and blow toward the ceramic core, so as to effectively clean the outer wall of the ceramic core, avoid the adhesion of impurities and dust resulting in reduced detection accuracy, and improve the detection accuracy. In addition, the downward wind force will also give the clamping plate 71 a downward thrust, so as to achieve more effective clamping and improve the stability of the ceramic core during the detection process.

[0045] Reference Figure 1-Figure 8The present invention is used in that the pull rod 73 is first pulled upward to move the clamping plate 71 into the clamping box 7, and then the ceramic core to be tested is placed on the center of the alignment mark 81 of the test table 1, and then the pull rod 73 is slowly released, and the clamping plate 71 is fitted with the top of the ceramic core under the rebound action of the clamping spring 72, so as to utilize the rebound force of the clamping spring 72 to fix the ceramic core, facilitate operation, and improve the detection efficiency; then the driving motor 5 is turned on, and through the meshing relationship between the single-tooth gear 52 and the rotating toothed disc 51, when the single-tooth gear 52 rotates one circle, the rotating toothed disc 51 will rotate a distance of one tooth, thereby driving the rotating ring 3 to rotate continuously, and when the single-tooth gear 52 rotates, the piston plate 311 and the strong magnetic plate 64 are utilized. The repulsive effect will push the piston plate 311 upward, thereby compressing the gas in the piston groove 31, and causing part of the gas to push the lifting plate 61 upward, so that the mounting rod 62 moves up with the 3D scanner 2 to the upper limit ring 66, and then the piston plate 311 and the strong magnetic plate 64 are separated from the repulsive effect. At this time, under the action of gravity, the lifting plate 61 will move downward, thereby realizing a comprehensive detection of the ceramic core in the vertical direction of a single angle, and with the rotation of the rotating ring 3, the 3D scanner 2 will continuously switch angles to complete the comprehensive detection of the ceramic core, effectively improving the detection accuracy and efficiency, and finally the 3D scanner 2 will transmit all measurement data to the 3D simulation terminal to form a 3D model, thereby obtaining all dimensional information of the ceramic core.

[0046] When the lifting plate 61 moves upward along the lifting cylinder 6, the gas in the lifting cylinder 6 will be squeezed and the one-way valve in the air guide pipe 75 will be opened, so that this part of the gas will enter the clamping box 7 along the air guide pipe 75, the rotating ring 3 and the blowing groove 41. At this time, the air flow will pass downward through the blowing hole 711 and blow toward the ceramic core, so as to effectively clean the outer wall of the ceramic core, avoid the adhesion of impurities and dust, and cause the detection accuracy to decrease, thereby improving the detection accuracy, and the downward wind force will also give the clamping plate 71 a downward thrust, so as to achieve more effective clamping, thereby improving the stability of the ceramic core during the detection process; when the lifting plate 61 moves down and resets, a suction effect will be generated in the upper cavity of the lifting cylinder 6. At this time, the one-way valve in the suction groove 621 will be opened, so that the external airflow enters the lifting cylinder 6 along the dust suction pipe 631 and the suction groove 621, so as to supplement the blowing airflow, and secondly, it can speed up the gas flow rate at the scanning end of the three-dimensional scanner 2, thereby sucking away the dust attached to it, ensuring the cleanliness of the scanning end of the three-dimensional scanner 2 and improving the final detection accuracy.
