Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing tooling technology, and in particular to a testing tooling for long, thin-walled castings. Background Technology
[0002] With the development of the machinery industry, lightweighting of castings has become a mainstream direction for cost control in the machinery industry. While ensuring the rigidity, strength, and safety performance of castings, using thin-walled castings to control the weight of components is an important way to achieve lightweighting. However, during the production process of ductile iron thin-walled components, stress and issues with handling and placement can often lead to casting deformation (deformation of castings affects the assembly and performance of the product). Existing methods such as... Figure 1 For long, thin-walled castings, deformation is usually checked manually. Common inspection methods include visual inspection and laser scanning. However, visual inspection has low accuracy and limitations, and often requires the use of calipers and other inspection tools, which seriously affects the inspection efficiency. Laser scanning is cumbersome, requiring scanning first and then comparing with a 3D image, resulting in a long inspection cycle and low efficiency. It is generally not used for the inspection of all products in the same batch. Therefore, this utility model proposes a tooling for inspecting long, thin-walled castings. Utility Model Content
[0003] The purpose of this utility model is to address the problem in the background technology that the deformation of long thin-walled castings is usually checked and confirmed manually. Common inspection methods include visual inspection and laser scanning inspection. However, visual inspection has low accuracy and great limitations, and usually requires the use of inspection tools such as calipers, which seriously affects the inspection efficiency of castings. Secondly, laser scanning inspection is relatively cumbersome, and it requires scanning first and then comparing with 3D images, so the inspection cycle is long and the inspection efficiency is relatively low. It is generally not used for the inspection of all products in the same batch of castings. Therefore, this utility model proposes an inspection fixture for long thin-walled castings.
[0004] The technical solution of this utility model is as follows: a tooling for inspecting long thin-walled castings, comprising: a base for support, a first horizontal inspection component for horizontal inspection of the long thin-walled castings being provided on the upper surface of the base, and a second horizontal inspection component being fixedly provided on the opposite side of the first horizontal inspection component; a rear inspection block fixedly provided on the opposite side of the first horizontal inspection component for inspecting the rear side of the long thin-walled castings; and a front inspection block provided on the upper surface of the base for inspecting the front side of the long thin-walled castings.
[0005] Optionally, the first level detection component includes a set of level detection blocks fixedly disposed on the upper surface of the base, and the upper end of each level detection block is provided with a first level detection groove.
[0006] Optionally, the second horizontal detection component includes a left horizontal detection block and a right horizontal detection block fixedly arranged on the upper surface of the base, and second horizontal detection grooves are respectively formed at the upper ends of the left horizontal detection block and the right horizontal detection block.
[0007] Optionally, the rear detection block is arranged in a "C" - shaped structure, and the rear detection block and the horizontal detection block are integrally formed.
[0008] Optionally, the front detection block is arranged in a "U" - shaped structure.
[0009] Optionally, the left horizontal detection block is higher than the right horizontal detection block.
[0010] Optionally, rubber blocks are respectively arranged inside the first horizontal detection groove and the second horizontal detection groove.
[0011] Optionally, the horizontal detection block, the left horizontal detection block and the right horizontal detection block are located in the same vertical plane.
[0012] In summary, the present application includes at least the following beneficial technical effects:
[0013] By arranging the horizontal detection block in the first horizontal detection component, the first horizontal detection groove, the left horizontal detection block, the right horizontal detection block, the second horizontal detection groove in the second horizontal detection component, and cooperating with the rear detection block and the front detection block, the utility model can perform multi - directional horizontal detection on the long - shaped thin - wall casting, greatly improving the detection accuracy. There is no need to rely on additional detection tools such as calipers, avoiding the errors of manual measurement or repeated measurement, significantly improving the inspection efficiency of the casting. And this tooling is easy to operate, without complex comparison. Workers only need to place the long - shaped thin - wall casting at the corresponding position of the tooling, and then can directly perform detection, greatly shortening the detection cycle and improving the detection efficiency, especially suitable for large - scale and rapid detection of products in the same batch;
[0014] Furthermore, by arranging rubber blocks inside the first horizontal detection groove and the second horizontal detection groove, the rubber blocks are soft and elastic, which can effectively avoid friction caused by rigid contact during the detection of the long - shaped thin - wall casting. This not only reduces the risk of damage such as scratches and abrasions on the casting surface, but also greatly improves the product quality and reduces the defective rate.

[0029] Embodiment
[0030] As Figures 1 to 3 shown, a detection tool for long thin-walled castings proposed by the present utility model includes: a base 1 for support, and a first horizontal detection component 2 for horizontally detecting the long thin-walled casting 10 is arranged on the upper surface of the base 1. The first horizontal detection component 2 includes a group of horizontal detection blocks 21 fixedly arranged on the upper surface of the base 1, and the horizontal detection blocks 21 are symmetrically arranged. First horizontal detection grooves 22 are respectively opened at the upper ends of the horizontal detection blocks 21, which can stably support the long thin-walled casting 10 and prevent displacement during the detection process; second horizontal detection components 3 are respectively fixedly arranged on the opposite surfaces of the first horizontal detection component 2. The second horizontal detection component 3 includes a left horizontal detection block 31 and a right horizontal detection block 32 fixedly arranged on the upper surface of the base 1. The left horizontal detection block 31 and the right horizontal detection block 32 are symmetrically arranged and are respectively used for detecting the left and right sides of the long thin-walled casting 10. Second horizontal detection grooves 33 are respectively opened at the upper ends of the left horizontal detection block 31 and the right horizontal detection block 32, which can stably support the long thin-walled casting 10 and increase the accuracy of the detection; a rear detection block 4 fixedly arranged on the opposite surface of the first horizontal detection component 2 for detecting the rear side of the long thin-walled casting 10 is in a "C" - shaped structure, which can detect whether the long thin-walled casting 10 is tightly and stably adhered to it, facilitating the detection of the long thin-walled casting 10. The rear detection block 4 and the horizontal detection block 21 are integrally formed; a front detection block 5 arranged on the upper surface of the base 1 for detecting the front side of the long thin-walled casting 10 is in a "U" - shaped structure, which is convenient for judging whether the long thin-walled casting 10 has deformation or dimensional deviation.
[0031] As Figure 1 and Figure 4 shown, the left horizontal detection block 31 is higher than the right horizontal detection block 32, which is more convenient for observing whether the long thin-walled casting 10 is inclined and improves the detection efficiency.
[0032] Furthermore, rubber blocks 6 are respectively arranged inside the first horizontal detection grooves 22 and the second horizontal detection grooves 33, which can reduce the rigid contact between the long thin-walled casting 10 and the detection blocks and prevent damage to the surface of the long thin-walled casting
[0033] Furthermore, the horizontal detection block 21, the left horizontal detection block 31, and the right horizontal detection block 32 are located in the same vertical plane, which can avoid repeated direction inspection of the casting and improve the detection efficiency.
[0034] The working principle of this embodiment is as follows: Before detecting the long and thin-walled casting 10, it is necessary to first perform shot blasting, deburring, and grinding operations on the long and thin-walled casting 10 to remove burrs, scale impurities generated on the casting surface due to the casting process, making the casting surface flat and smooth. At the same time, the smooth surface helps to more accurately judge the fitting situation between the casting and each component of the detection tooling during the subsequent detection process, avoiding deviation of the detection results caused by surface impurities and ensuring the accuracy of the detection.
[0035] The polished long and thin-walled casting 10 is placed on the first horizontal detection component 2. The first horizontal detection groove 22 on a group of horizontal detection blocks 21 in the first horizontal detection component 2 preliminarily positions and supports the long and thin-walled casting 10 in the horizontal direction from below, ensuring the preliminary stability of the casting on the horizontal plane. At the same time, the second horizontal detection component 3 located on the opposite side of the first horizontal detection component 2, that is, the second horizontal detection grooves 33 on the left horizontal detection block 31 and the right horizontal detection block 32, further constrain and position the casting in the horizontal direction from the side, preventing the casting from shifting in the horizontal direction and ensuring the accuracy of the casting position during the detection process. Since the left horizontal detection block 31 is higher than the right horizontal detection block 32, it is convenient for operation and also facilitates employees to visually observe the interference between the casting and the tooling.
[0036] After the casting is placed in place, it enters the detection link. By visual inspection, observe whether there is interference between the casting and the detection block. The rear detection block 4 has a "C" - shaped structure and is integrally formed with the horizontal detection block 21. It is used to detect from the rear side of the casting, mainly to check whether the shape and size of the rear side of the casting meet the standards, and to check whether there are abnormal situations such as too large or too small gaps between the rear side of the casting and the rear detection block 4, so as to judge whether there are deformation and dimensional deviation problems on the rear side of the casting.
[0037] The front detection block 5 has a "U" - shaped structure and is used to detect from the front side of the casting. It is also used to observe the cooperation between the front side of the casting and the front detection block 5 to judge the quality of the front side of the casting. In addition, the rubber blocks 6 arranged inside the first horizontal detection groove 22 and the second horizontal detection groove 33 play a buffering and protecting role during the detection process. On the one hand, it prevents the detection tooling from scratching the casting surface during the detection process; on the other hand, the elasticity of the rubber block 6 can make the casting better fit with the detection groove, compensating for the errors caused by the slight deformation of the casting or the machining accuracy of the detection tooling to a certain extent, improving the accuracy of the detection. By observing the compression deformation of the rubber block 6, it can also assist in judging whether the casting fits well with the detection groove.
[0038] After the inspection of a casting is completed, the inspected workpiece is removed. This operation completes the reset process of the inspection fixture, preparing for the placement of the next workpiece to be inspected, thereby realizing the continuous inspection of the long thin-walled casting 10.
[0039] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
