Abstract
Description
Technical Field
[0001] This invention relates to the field of aluminum alloy casting thickness measurement technology, specifically to an aluminum alloy casting thickness measuring instrument. Background Technology
[0002] After aluminum alloy castings are manufactured and processed, their wall thickness needs to be measured to determine whether the quality of the aluminum alloy castings is qualified. Currently, laser thickness measuring instruments are used in the market for measurement. Due to the advantages of non-contact measurement, fast measurement speed and high accuracy, laser thickness measuring instruments are widely used and can measure high-temperature castings. For example, the patent application published in the prior art with the publication number "CN118960592B" is entitled "A High-Precision Stainless Steel Casting Thickness Measuring Instrument and its Measuring Method." It discloses that a clamping plate rotates 90 degrees to fit against the outer wall of the stainless steel casting, thereby fixing the casting. Since the distance between the first and second laser measuring instruments is fixed, the thickness of the stainless steel casting can be obtained by subtracting the values measured by the first and second laser measuring instruments from the distance between them. After the thickness measurement at one location is completed, the second drive motor is intermittently started. The output of the second drive motor drives a disc to rotate the stainless steel casting in a circular motion, thus performing different position detections on the casting. The first drive motor is then started, and its output intermittently starts and stops. The output of the first drive motor drives a one-way threaded screw to rotate, thereby driving a sliding seat to move the stainless steel casting intermittently laterally. This, combined with the circumferential measurement of the stainless steel casting, enables comprehensive thickness measurement.
[0003] The thickness measuring instruments in the prior art described above only have one first laser measuring instrument and one second laser measuring instrument, which cannot be used for comparative measurement. When the internal components of the first and second laser measuring instruments age or are damaged after long-term use, the measurement results of the first and second laser measuring instruments will fluctuate greatly and have obvious deviations. As a result, the thickness measuring instrument for aluminum alloy castings has poor accuracy in measuring thickness, which affects the thickness inspection operation. Therefore, we propose an aluminum alloy casting thickness measuring instrument to solve the problems mentioned above. Summary of the Invention

[0010] Preferably, the rotation adjustment component includes a rotating disk penetratingly arranged on the outer side below the vertical rod, and the lower part of the rotating disk is rotatably connected to the inside of the storage protection frame. A scroll spring is nested and connected to the outer side below the rotating disk, and a connecting rope is wound and connected to the outer side above the rotating disk. The rotating disk is arranged in a "dry" shape structure. Clamping grooves are symmetrically opened on the outer side surface of the vertical rod. Clamping blocks are symmetrically installed on the inner side wall of the rotating disk, and the clamping blocks are in clamping and sliding connection with the clamping grooves.
[0011] Preferably, a rope winding rod is rotatably installed on the bottom surface of the support plate, and the upper end of the connecting rope penetrates through the side wall of the storage protection frame and is wound and connected to the outer side of the rope winding rod through a guide wheel.
[0012] Preferably, a sealing ring is fixed on the inner side wall below the storage protection frame. The sealing ring is arranged in a "return" shape structure.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The thickness measuring device for aluminum alloy castings can compare the two detection data to know whether the two laser distance measuring components are damaged. Therefore, it can avoid the poor accuracy of thickness measurement caused by the damage of the laser distance measuring components, and then improve the measurement accuracy of the entire thickness measuring device for aluminum alloy castings. The specific content is as follows: (1) Laser ranging components are symmetrically installed on both the left and right sides of the mounting frame. Therefore, by rotating the adjustment component, the mounting frame can be rotated so that the two laser ranging components on the left and right sides of the mounting frame can perform thickness detection separately. The two detection data can be compared to determine whether the two laser ranging components are damaged. This avoids the poor accuracy of thickness measurement due to damage to the laser ranging components, thereby improving the measurement accuracy of the entire aluminum alloy casting thickness measuring device. (2) By further setting the transmission rack, the laser ranging component can be stored inside the storage and protective frame when not in use. At the same time, the sealing ring can prevent external dust and moisture from entering the storage and protective frame, thus protecting the laser ranging component well. Therefore, the service life of the laser ranging component can be improved, the laser ranging component can be prevented from being damaged, and the accuracy of the thickness measurement of the thickness measuring device can be further improved. (3) The control rod can rotate the support plate, the storage and protection frame and the mounting frame together, so that the mounting frame can be parallel to the inclined surface of the aluminum alloy casting being measured. Therefore, the thickness measuring device can measure the thickness of the inclined surface of the aluminum alloy casting to meet different usage requirements. At the same time, two laser ranging components are installed on both sides of the mounting frame. When the two laser ranging components on the same side measure the same value, it means that the mounting frame can be parallel to the inclined surface of the aluminum alloy casting being measured, which makes it easy to adjust the inclination of the mounting frame.

[0018] 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.
[0019] Please see Figures 1-12 The present invention provides the following technical solution: Example 1: The aluminum alloy casting thickness measuring device in this example can perform comparative measurements when measuring the thickness of the vertical surface of a shell-shaped aluminum alloy casting. This avoids poor thickness measurement accuracy due to damage to the laser ranging component 71, thereby improving the overall measurement accuracy of the aluminum alloy casting thickness measuring device. The specific structure is shown in the attached diagram. Figures 1-9 As shown, a horizontal plate 1 and an electric push rod 2 are installed through it. The right side of the horizontal plate 1 is connected to the placement platform 5 below via a bracket. The output end of the electric push rod 2 is connected to a support connection assembly. The support plate 3 inside the support connection assembly has storage and protective frames 4 installed on both the left and right sides below. The storage and protective frames 4 are installed with a lifting control assembly inside the lower part of the storage and protective frames 4. Laser ranging components 71 are embedded in both the left and right sides of the installation frame 7. A rotation adjustment assembly is installed on the outside of the lifting control assembly. A first threaded rod 51 is installed in the groove inside the upper surface of the placement platform 5. A moving block 52 is threaded to the outside of the first threaded rod 51. The lower part of the moving block 52 is engaged and slidably connected with the groove opened inside the upper surface of the placement platform 5. A clamping seat 53 is rotatably installed above the moving block 52. An aluminum alloy casting of the thickness to be measured is installed above the clamping seat 53 via a clamp.
[0020] The support connection component includes a support plate 3, and the middle position above the support plate 3 is fixedly connected to the output end below the electric push rod 2. The support rods 31 are symmetrically and rotatably installed on the upper surface of the support plate 3. The bottom surface of the cross plate 1 is symmetrically grooved and installed with guide cross bars 101. The outer sides of the guide cross bars 101 are slidably connected through the connection seats 102. The outer sides above the connection seats 102 are snap-fitted and slidably connected to the grooves opened on the bottom surface of the cross plate 1. The bottom surface of the connection seat 102 is rotatably connected to the upper ends of the support rods 31. The elevation control component includes a second threaded rod 10 installed in the groove opened in the storage and protection frame 4. The outer side of the second threaded rod 10 is threadedly connected through a moving disk 8. The lower part of the moving disk 8 is rotatably installed with a vertical rod 81. The lower part of the vertical rod 81 penetrates through the inside of the storage and protection frame 4 and is fixedly connected to the upper surface of the installation frame 7. The outer side of the upper part of the storage and protection frame 4 is rotatably installed with a transmission rod 11. One end of the transmission rod 11 located inside the storage and protection frame 4 forms a transmission structure with the outer side of the upper end of the second threaded rod 10 through a bevel gear set. The outer side of the other end of the transmission rod 11 is key-connected with a transmission gear 111. Fixed racks 12 are installed on the lower sides of the left and right sides of the cross plate 1. The rear sides of the fixed racks 12 are meshed with the transmission gear 111. The rotation adjustment component includes a rotating disk 9 penetrating through the outer side of the lower part of the vertical rod 81. The lower part of the rotating disk 9 is rotatably connected to the inside of the storage and protection frame 4. A scroll spring 92 is nested and connected to the outer side below the rotating disk 9. A connecting rope 91 is wound and connected to the outer side above the rotating disk 9. The rotating disk 9 is arranged in a "dry" shape structure. Clamping grooves 82 are symmetrically opened on the outer side surface of the vertical rod 81. Clamping blocks 93 are symmetrically installed on the inner side wall of the rotating disk 9. The clamping blocks 93 are snap-fitted and slidably connected to the clamping grooves 82. A rope winding rod 6 is rotatably installed on the bottom surface of the support plate 3. The upper end of the connecting rope 91 penetrates through the side wall of the storage and protection frame 4 and is wound around the outer side of the rope winding rod 6 through a guide wheel. A sealing ring 41 is fixed on the inner side wall below the storage and protection frame 4. The sealing ring 41 is arranged in a "return" shape structure. The inner side wall of the sealing ring 41 is closely fitted with the outer side surface below the installation frame 7. The lower part of the sealing ring 41 is in an open shape setting.
[0021] First, as shown in the appendix Figure 1-3As shown, the aluminum alloy casting in the shape of a shell is placed on the clamping seat 53. The aluminum alloy casting in the shape of a shell can be fixed on the clamping seat 53 by a clamp or a suction cup. Since this part is prior art, it will not be described in detail here, and the clamp or suction cup is not shown in detail in the figure. Then, the thickness of the right vertical surface of the aluminum alloy casting in the shape of a shell is measured. The electric push rod 2 is started. The output end of the electric push rod 2 drives the support plate 3 to move downward. The support plate 3 drives the two storage protective frames 4 to move downward. At this time, the support rod 31 drives the connecting seat 102 to move inward outside the guide crossbar 101. The support rod 31 can provide stable support force to the support plate 3. This allows the support plate 3 to rise and fall stably. When the storage and protective frame 4 moves downward, the outer transmission gear 111 meshes with the fixed rack 12, causing the transmission gear 111 to drive the internal transmission rod 11 to rotate. The transmission rod 11 drives the second threaded rod 10 to rotate through the bevel gear set. When the second threaded rod 10 rotates, it drives the outer threaded movable disk 8 to move downward. The movable disk 8 drives the vertical rod 81 and the mounting frame 7 to move downward. At this time, the snap-fit groove 82 moves downward outside the snap-fit block 93. When the transmission gear 111 descends to the point of separating from the fixed rack 12, the transmission gear 111 stops rotating. At this time, the mounting frame 7 moves out of the storage and protective frame 4, as shown in the attached figure. Figure 7 As shown, the electric push rod 2 then continues to drive the storage and protection frame 4 and the mounting frame 7 to move downwards. When the mounting frame 7 moves to the appropriate position, the movement of the mounting frame 7 stops. At this time, the laser ranging component 71 inside the right side of the mounting frame 7 on the left measures the distance to the right vertical surface of the aluminum alloy casting as D1. Similarly, the laser ranging component 71 inside the left side of the mounting frame 7 on the right measures the distance to the right vertical surface of the aluminum alloy casting as D2. Since the distance between the laser ranging component 71 inside the right side of the mounting frame 7 on the left and the laser ranging component 71 inside the left side of the mounting frame 7 on the right is fixed at D3, it can be known that the thickness of the right vertical surface of the aluminum alloy casting is D4 = D3 - D1 - D2.
[0022] Next, the lower end of the rope-winding rod 6 can be connected to an external motor via a coupling. The motor drives the rope-winding rod 6 to rotate. When the rope-winding rod 6 rotates, it simultaneously pulls and winds the connecting ropes 91 on both sides, causing the lower end of the connecting ropes 91 to drive the rotating disk 9 to rotate. Then, because the locking block 93 on the inner side of the rotating disk 9 engages and slides with the locking groove 82, the rotating disk 9 drives the vertical rod 81 and the mounting frame 7 to rotate 180° together. Since the upper end of the vertical rod 81 is connected to the moving disk 8 by a bearing, the moving disk 8 does not rotate. After the mounting frame 7 rotates 180°... The laser ranging component 71 mounted on the other side of the mounting frame 7 then begins to perform thickness measurement, as described above. Finally, the data from the two measurements are compared. If the values are the same, it indicates that the laser ranging component 71 is not damaged. If the values differ significantly, it indicates that the laser ranging component 71 is damaged, meaning that there is an error in the thickness measurement. In this case, another thickness measuring device needs to be used to perform the thickness measurement again. The probability of the laser ranging components 71 on both sides of the mounting frame 7 being damaged simultaneously is small, so this situation is not considered.
[0023] Next, the mounting frame 7 can be lowered further, and the thickness of other height positions on the right vertical surface of the aluminum alloy casting can be measured as described above. The first threaded rod 51 can be rotated by an external motor, causing the first threaded rod 51 to move the outer threaded connecting moving block 52 forward or backward. The moving block 52 moves the clamping seat 53 and the aluminum alloy casting forward or backward. Therefore, the thickness of different positions on the right side of the aluminum alloy casting can be measured. The motor inside the moving block 52 can drive the clamping seat 53 and the aluminum alloy casting to rotate, allowing the thickness of different sides of the aluminum alloy casting to be measured, meeting different usage requirements.
[0024] After the thickness measuring device has been used, as described above, the electric push rod 2 moves the support plate 3 upward, causing the storage and protective frame 4 to move the mounting frame 7 upward. When the transmission gear 111 moves upward and engages with the fixed rack 12, the transmission gear 111 drives the transmission rod 11 to rotate in the opposite direction. The transmission rod 11 drives the second threaded rod 10 to rotate in the opposite direction through the bevel gear set, causing the second threaded rod 10 to move the moving disk 8, the vertical rod 81, and the mounting frame 7 upward. Then, the mounting frame 7 enters the storage and protective frame 4, and the inner wall of the sealing ring 41 fits tightly against the lower outer side of the mounting frame 7. The sealing ring 41 fits against the bottom surface of the mounting frame 7 to seal the bottom of the protective frame 4, preventing dust, sand, or moisture from the outdoor environment from entering the protective frame 4 and depositing on the surface of the laser ranging component 71. This prevents the laser beam emission and reception accuracy within the laser ranging component 71 from being affected, the stability of the electronic components within the laser ranging component 71 from being affected, and measurement errors from being caused. This effectively protects the laser ranging component 71, thus extending its service life, preventing damage to the laser ranging component 71, and further improving the accuracy of the thickness measurement by the thickness measuring device.
[0025] Example 2: Based on Example 1, this example of the aluminum alloy casting thickness measuring device discloses a different supporting connection assembly structure. This allows the thickness measuring device to measure the thickness of the inclined surface of a shell-shaped aluminum alloy casting, thus meeting different usage requirements. For the specific structure, please refer to the attached diagram. Figures 10-12 As shown, the support connection assembly includes a support frame 32 located below the horizontal plate 1, and the support frame 32 is arranged in an inverted "U" shape. An adjustment rod 33 is rotatably installed inside the support frame 32, and a support plate 3 is fixedly installed on the outside of the adjustment rod 33 located inside the support frame 32. The upper middle position of the support frame 32 is fixedly connected to the output end below the electric push rod 2. A support rod 31 is symmetrically rotatably installed on the upper surface of the support frame 32, and the support plate 3 forms a rotating structure with the adjustment rod 33 as the center.
[0026] When it is necessary to measure the thickness of the inclined surface of an aluminum alloy casting with a shell shape, first activate the electric push rod 2. The output end of the electric push rod 2 drives the support frame 32 to move downward. The support frame 32 drives the support plate 3 and the storage and protection frame 4 to move downward. Similarly, as described above, when the storage and protection frame 4 moves downward, the fixed rack 12 is engaged with the transmission gear 111, causing the mounting frame 7 to move downward and separate from the storage and protection frame 4. Then, the front end of the adjusting rod 33 is connected to an external motor through a coupling. The motor drives the adjusting rod 33 to rotate, adjusting... The control lever 33 drives the support plate 3, the storage and protection frame 4, and the mounting frame 7 to rotate and tilt. At the same time, the two laser ranging components 71 on the same side of the mounting frame 7 perform thickness measurement. When the measurement values of the two laser ranging components 71 on the same side of the mounting frame 7 are the same, it means that the mounting frame 7 has rotated to be parallel to the tilted surface of the aluminum alloy casting being measured. At this time, the rotation of the control lever 33 is stopped. Then, as shown above, the thickness measuring device can measure the thickness of the tilted surface of the aluminum alloy casting, thus meeting different testing needs.
[0027] Example 3: The aluminum alloy casting thickness measuring device in this example, based on Example 1, does not require the rotating disk 9, connecting rope 91, spiral spring 92, and rope winding rod 6. Instead, a motor can be directly installed on the moving disk 8, which directly drives the vertical rod 81 and the mounting frame 7 to rotate 180°, thereby further improving the accuracy and stability of the rotation of the mounting frame 7.

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.
