Description

Technical Field

[0001] This utility model relates to the field of casting mold inspection technology, and in particular to a casting mold flatness inspection mechanism. Background Technology

[0002] A casting mold flatness inspection mechanism is a device used to inspect the flatness of the surface of a casting mold. Through high-precision measuring equipment and mechanical structures, especially for rectangular molds whose surfaces typically have grooves—grooves used during the casting process to form specific structures in the casting—the mechanism accurately measures the flatness of the casting mold surface. This ensures that the mold meets design requirements during manufacturing, thereby improving the quality and consistency of the castings.

[0003] A typical casting mold flatness inspection mechanism consists of an inspection mechanism, a support mechanism, and a placement mechanism. Therefore, during use, the support mechanism provides stable positioning for the inspection mechanism, the placement mechanism is used to fix and place the casting mold to be inspected to ensure its stability during the inspection process, and the inspection mechanism scans the surface of the casting mold.

[0004] However, in some existing devices, the placement mechanism usually uses a simple clamping device to fix the casting mold. These clamping devices will deviate when rotating in multiple directions for inspection, and cannot adapt to fixing different lengths. The fixing effect is poor, which will cause deviations during inspection. Therefore, a casting mold flatness inspection mechanism is proposed to solve the above problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figure 2 , Figure 5 and Figure 6This utility model provides an embodiment of a casting mold flatness detection mechanism, including a base 1. A clamping mechanism 2 is provided on the top of the base 1. Pneumatic rods 3 are fixedly connected around the top of the base 1, and their design provides good telescopic capability. A top plate 4 is fixedly connected to the top of multiple pneumatic rods 3. The telescopic movement of the pneumatic rods 3 can drive the top plate 4 to extend to different heights. A testing mechanism 5 is provided at the bottom of the top plate 4. The testing mechanism 5 includes a transverse guide rail 51, which is designed to provide good lateral sliding capability. The outer side of the transverse guide rail 51 is fixedly connected to the bottom of the top plate 4. A sliding plate 52 is slidably connected to the outer side of the transverse guide rail 51. The lateral guiding capability provided by the transverse guide rail 51 enables the sliding plate 52 to slide smoothly laterally. A longitudinal guide rail 53 is fixedly connected to the bottom of the sliding plate 52, and its design provides good longitudinal sliding capability. The longitudinal guide rail 53 is slidably connected to a slide plate 54. The longitudinal guide rail 53 provides longitudinal sliding guidance, which enables the slide plate 54 to slide longitudinally. At the same time, the slide plate 52 slides outside the transverse guide rail 51, which enables multi-angle sliding capability and allows for comprehensive detection of objects. The outer side of the connecting plate 6 is fixedly connected to the outer side of the slide plate 54. The bottom of the slide plate 54, i.e., the outer side away from the transverse guide rail 51, is provided with a sensing head 55, which is designed to measure the flatness of the surface of the casting mold. Its measurement accuracy directly affects the accuracy of the detection results. The outer side of the testing mechanism 5 is fixedly connected to the connecting plate 6, which is designed to provide good support. At the same time, when the slide plate 54 slides in different positions, it enables the connecting plate 6 to move in different positions. The top of the connecting plate 6 is provided with a cleaning mechanism 7.

[0036] The clamping mechanism 2 includes a motor 21, designed to provide good driving capability. The motor 21 is externally fixedly connected to the bottom of the base 1. A support plate 22 is fixedly connected to the output end of the motor 21. The motor 21 drives the support plate 22 to rotate. A placement plate 23 is fixedly connected to the top of the support plate 22, designed to provide good support capability. The rotation of the support plate 22 drives the placement plate 23 to rotate. A pressing assembly is slidably connected inside the placement plate 23. The pressing assembly includes multiple sliding blocks 24, designed to provide good sliding capability. The multiple sliding blocks 24 are externally slidably connected to the top of the placement plate 23. Two sliding grooves 25 are formed on the top of the placement plate 23, designed to provide good sliding capability. A good sliding space allows the sliding block 24 to slide smoothly inside the sliding groove 25. Multiple sliding blocks 24 are externally slidably connected to the inside of two sliding grooves 25. Compression springs 26 are fixedly connected to adjacent sides of the multiple sliding blocks 24, providing good compression force. Guide posts are installed inside to prevent the compression springs 26 from shifting during compression and reset. The bottom of the clamping plate 27 is fixedly connected to the top of the multiple sliding blocks 24. Sliding the sliding blocks 24 to both sides allows the clamping plate 27 to separate. The top of the compression assembly is fixedly connected to the clamping plate 27, which is designed to effectively clamp the rectangular object being detected, preventing shifting during detection. The clamping plates 27 can also separate from each other, allowing... The device is designed to fix objects of different lengths. Specifically, by pulling the clamping plate 27 apart, the sliding block 24 can stretch the compression spring 26. After placing the object inside the clamping plate 27, the clamping plate 27 is released, allowing the compression spring 26 to reset, thus fixing the object. Limiting components are fixedly connected to the outer sides of the clamping plate 27. The limiting components include multiple support rods 212, which are designed to provide good support. The multiple support rods 212 are fixedly connected to the outer side of the clamping plate 27. Support columns 211 are fixedly connected to the adjacent sides of the multiple support rods 212, which are also designed to provide good support. Two cams 213 are externally rotatably connected to the clamping plate 27. Supported by these cams 213, the clamping plate 27 rotates. The convex surfaces of the cams 213 then press against the top of the placement plate 23, securing the clamping plate 27. A lever plate is mounted on the outside of the cams 213, which rotates the cams 213. Alignment posts 28 are fixedly connected to the outer sides of the clamping plate 27, providing excellent alignment capability. Alignment grooves 29 are formed on the outer sides of the clamping plate 27. When the clamping plates 27 approach each other, the alignment posts 28 slide into the alignment grooves 29, ensuring good alignment capability.Pads 210 are fixedly connected to both sides of the inner wall of the clamping plate 27, and their design is capable of causing damage to the object.

[0037] Reference Figure 1 , Figure 3 and Figure 4 The cleaning mechanism 7 includes a vacuum cleaner 71, designed to provide excellent suction power. The vacuum cleaner 71 generates negative pressure to draw in dust and impurities, which are then filtered and collected by a filtration system. The vacuum cleaner 71 is externally and fixedly connected to the top of the connecting plate 6. A connecting pipe 72 is fixedly connected to one side of the vacuum cleaner 71. When the vacuum cleaner 71 is activated, impurities are drawn into the vacuum cleaner 71 through the connecting pipe 72. A conveying pipe 74 is slidably connected to the other side of the connecting pipe 72. This conveying pipe 74 is designed to provide excellent conveying capacity, allowing impurities to be first drawn into the conveying pipe 74 and then conveyed into the connecting pipe 72. Simultaneously, the conveying pipe 74 can slide against the inner wall of the connecting plate 6. A tapered head 76 is fixedly connected to the bottom of the delivery pipe 74. Its design is capable of vacuuming impurities in different rectangular gaps being inspected. A telescopic rod 73 is fixedly connected to the top of the connecting plate 6. Its design provides good telescopic capability. A connecting block 75 is fixedly connected to the outside of the telescopic rod 73. Its design provides good connection capability. The extension and retraction of the telescopic rod 73 can drive the delivery pipe 74 to extend and retract. Before inspection, the delivery pipe 74 is extended by the telescopic rod 73, allowing vacuuming of the gaps between objects. After cleaning, the delivery pipe 74 can be extended and retracted by the telescopic rod 73, and then inspection is carried out. The outer side of the connecting block 75 is fixedly connected to the outside of the delivery pipe 74.

[0038] Working principle: First, by manually pulling the clamping plate 27 to both sides, the sliding block 24 slides within the sliding groove 25, causing the compression spring 26 to stretch. Once the clamping plate 27 is in the appropriate position, the casting mold is placed between the clamping plates 27. The clamping plate 27 is then released, the compression spring 26 returns to its original position, and the sliding block 24 and clamping plate 27 move towards the center, thus clamping and fixing the casting mold. At this time, the alignment posts 28 on both sides of the outer side of the clamping plate 27 slide into the alignment groove 29, ensuring accurate alignment of the clamping plate 27. The pads 210 on both sides of the inner wall of the clamping plate 27 contact the surface of the casting mold, providing protection and preventing damage to the casting mold during clamping. Simultaneously, the cam 213 rotates via the actuating plate, its convex surface pressing against the top of the placement plate 23, further fixing the clamping plate 27 and ensuring clamping stability. Meanwhile, the motor 21 can drive the clamping plate 27 to rotate at different angles for detection. Next, the pneumatic rod 3 is activated, and the height of the top plate 4 is adjusted according to the testing requirements to position the sensing head 55 of the testing mechanism 5 appropriately. Then, by controlling the transverse guide rail 51 and the longitudinal guide rail 53 in the testing mechanism 5, the sliding plate 52 slides on the transverse guide rail 51, while the sliding plate 54 slides on the longitudinal guide rail 53, driving the sensing head 55 to perform multi-angle sliding scans on the surface of the casting mold. The sensing head 55 measures the flatness of the casting mold surface during the testing process;

[0039] When cleaning dust and impurities from the surface and crevices of the casting mold is required, the vacuum cleaner 71 is first started, generating negative pressure. Through the connecting pipe 72, the vacuum cleaner 71 sucks in dust and impurities from the crevices of the casting mold. The connecting pipe 72 is connected to the conveying pipe 74, which is responsible for transporting the sucked-in dust and impurities to the filtration system inside the vacuum cleaner 71 for filtration and collection. During the cleaning process, the telescopic rod 73 extends and retracts as needed. When cleaning dust in more distant locations or deeper crevices is required, the telescopic rod 73 extends, causing the conveying pipe 74 to extend forward, allowing the conical head 76 at the bottom of the conveying pipe 74 to contact the target location. The conical head 76 is designed to adapt to rectangular crevices of different sizes, effectively sucking dust and impurities from the crevices into the conveying pipe 74. After cleaning is complete, the telescopic rod 73 retracts, causing the conveying pipe 74 to return to its initial position, preparing for subsequent inspection work. The connecting block 75 serves as a connection and support in this process, firmly connecting the telescopic rod 73 to the conveying pipe 74, ensuring that the conveying pipe 74 can move stably during the telescopic process without loosening or falling off. This cleaning process effectively removes dust and impurities from the surface of the sensing head 55 and the gaps in the casting mold, ensuring accurate detection of the casting mold's flatness.
