Abstract
Description
Technical Field
[0001] This application relates to the field of fin manufacturing technology, and more specifically, to a tooling for inspecting irregularly shaped fins. Background Technology
[0002] Air conditioner heat exchangers are mainly composed of fins and copper tubes. In order to further enhance the heat exchange effect and improve the heat exchange performance of the fins, the fins are processed into various hole shapes by bulging, punching and opening of molds. Because the hole shapes of these fins are so varied, they are called irregular fins.
[0003] To meet the production demands of irregularly shaped fins, corresponding equipment molds need to be developed. The irregularly shaped molds used to produce these fins typically correspond to a single type of irregularly shaped hole on the fin; a single mold cannot produce multiple different shapes of irregularly shaped holes. As air conditioning functions and performance diversify, the types of irregularly shaped fins also increase, meaning the types of irregularly shaped holes on these fins also increase accordingly.
[0004] Currently, there are many types of irregularly shaped fins, and the irregular holes often share similarities. The diversity in hole shape and number, as well as the borrowing of different irregular parts, increases the difficulty of production control for irregularly shaped fins. This can easily lead to the use of incorrect molds in the production of irregularly shaped fins, resulting in errors in the irregular holes on the fins, causing problems such as the heat exchanger being unable to bend or assembly abnormalities. To reduce this, during the production of irregularly shaped fins, workers visually inspect and verify the irregular holes. However, this visual inspection method relies heavily on the experience of the workers, is subjective, and is prone to errors. Utility Model Content
[0005] The purpose of this application is to provide a tooling for inspecting irregularly shaped fins, which can be used to identify and correct the irregular holes of the produced irregularly shaped fins. Compared with the method of visual inspection by workers, it can objectively and accurately identify and correct whether there are errors in the irregular holes of the produced irregularly shaped fins. Moreover, it is extremely easy to use and can effectively improve the inspection efficiency of the produced irregularly shaped fins.
[0006] To achieve the above objectives, this application provides a non-standard fin inspection fixture, including a first non-standard fin inspection fixture. The first non-standard fin inspection fixture includes a first bearing base and a first non-standard block. The first non-standard block is disposed on the first bearing base, and the shape and size of the first non-standard block match the first non-standard hole on the qualified non-standard fin to be inspected.
[0007] In the implementation of the above technical solution, the first irregular shape inspection fixture is used to inspect the first irregular shape hole on the irregular shape fin to be inspected. That is, the operator can use the first irregular shape inspection fixture to identify and verify whether there is an error in the first irregular shape hole on the irregular shape fin to be inspected, so as to determine whether the irregular shape mold used to produce the irregular shape fin to be inspected is used correctly. Specifically, during inspection, the first irregular shape hole on the irregular shape fin to be inspected is aligned with the first irregular shape block of the first irregular shape inspection fixture, and the irregular shape fin to be inspected is placed on the first bearing base. If the irregular shape fin to be inspected can be placed on the first bearing base, and the first irregular shape hole on the irregular shape fin to be inspected is aligned with the first irregular shape block... A perfect match indicates that the first irregular hole of the fin under inspection is correct and the corresponding irregular mold is being used correctly. If the inspection reveals a different situation, it indicates that the first irregular hole of the fin under inspection is incorrect and the corresponding irregular mold is being used incorrectly. Compared to visual inspection by workers, this method can objectively and accurately identify and calibrate whether there are errors in the irregular holes of the produced fins. It is also extremely easy to use and can effectively improve the inspection efficiency of the produced fins. At the same time, if an incorrect irregular mold is found, it can be replaced in time to avoid continuous production of errors and reduce production costs.
[0008] In a preferred embodiment of this application, the first irregular block and the first bearing base are integrally formed.
[0009] In the implementation of the above technical solution, the first irregular block and the first bearing base adopt an integral molding structure, which can facilitate the production of the first irregular inspection tooling and reduce the production cost of the first irregular inspection tooling.
[0010] In a preferred embodiment of this application, the first irregular-shaped inspection fixture further includes a first positioning post.
[0011] The first positioning post is disposed on the first bearing base, and the shape and size of the first positioning post match the first positioning hole on the qualified irregular fin to be tested.
[0012] In the implementation of the above technical solution, the first positioning post of the first irregular fin inspection fixture can first position the irregular fin to be inspected on the first bearing base during inspection, so that the irregular fin to be inspected is placed on the first bearing base through the first positioning post. Then, the first irregular block identifies and calibrates the first irregular hole on the irregular fin to be inspected, and judges whether there are errors such as incorrect hole shape and position deviation of the first irregular hole on the irregular fin to be inspected. The setting of the first positioning post further improves the accuracy of the inspection of the first irregular hole on the irregular fin to be inspected.
[0013] In a preferred embodiment of this application, there are two first positioning posts, which are diagonally arranged on the first bearing base;
[0014] The qualified irregular fin to be tested has two first positioning holes. The positions of the two first positioning posts match the positions of the two first positioning holes, and the relative positions of the two first positioning posts and the first irregular block match the relative positions of the two first positioning holes and the first irregular hole.
[0015] In the implementation of the above technical solution, two first positioning posts are provided, and the two first positioning posts are diagonally arranged on the first bearing base. When the irregular fin to be tested is placed on the first bearing base through the first positioning posts, the irregular fin to be tested is more stable and avoids shaking, which would affect the test. In addition, the matching and limitation of the relative positions can make the first irregular fin testing fixture have extremely high accuracy in detecting the first irregular hole on the irregular fin to be tested, and can effectively eliminate some judgment errors caused by positional offset.
[0016] In a preferred embodiment of this application, the first positioning post and the first bearing base are integrally formed.
[0017] In the implementation of the above technical solution, the first positioning column and the first bearing base adopt an integral molding structure, which can facilitate the production of the first irregular-shaped inspection tooling and reduce the production cost of the first irregular-shaped inspection tooling.
[0018] In a preferred embodiment of this application, the irregular fin inspection fixture further includes a second irregular fin inspection fixture and / or a third irregular fin inspection fixture.
[0019] The second irregular shape inspection fixture includes a second bearing base and a second irregular shape block. The second irregular shape block is disposed on the second bearing base, and the shape and size of the second irregular shape block match the second irregular shape hole on the qualified irregular shape fin to be inspected.
[0020] The third irregular shape inspection fixture includes a third bearing base and a third irregular shape block. The third irregular shape block is disposed on the third bearing base, and the shape and size of the third irregular shape block match the third irregular shape hole on the qualified irregular shape fin to be inspected.
[0021] The first irregular block, the second irregular block, and the third irregular block are all different from each other, and the first irregular hole, the second irregular hole, and the third irregular hole are all different from each other.
[0022] In the process of implementing the above technical solution, the irregular fins to be inspected may have two or three types of irregular holes. The setting of the second irregular fin inspection fixture and the third irregular fin inspection fixture can facilitate the staff to simultaneously inspect the irregular fins to be inspected with different types of irregular holes, thereby improving the inspection efficiency.
[0023] In a preferred embodiment of this application, the second irregular block and the second bearing base are integrally formed; the third irregular block and the third bearing base are integrally formed.
[0024] In the implementation of the above technical solution, the second irregular block and the second bearing base adopt an integral molding structure, and the third irregular block and the third bearing base adopt an integral molding structure, which can facilitate the production and manufacturing of the second irregular inspection fixture and the third irregular inspection fixture, and reduce the production and manufacturing cost of the second irregular inspection fixture and the third irregular inspection fixture.
[0025] In a preferred embodiment of this application, the second irregular-shaped inspection fixture further includes a second positioning post.
[0026] The second positioning post is disposed on the second bearing base, and the shape and size of the second positioning post match the second positioning hole on the qualified irregular fin to be tested;
[0027] The third irregular-shaped inspection fixture also includes a third positioning column.
[0028] The third positioning post is disposed on the third bearing base, and the shape and size of the third positioning post match the third positioning hole on the qualified irregular fin to be tested.
[0029] In the process of implementing the above technical solution, the second positioning post and the third positioning post can further improve the accuracy of detecting the second and third irregular holes on the irregular fins to be inspected.
[0030] In a preferred embodiment of this application, there are two second positioning posts, which are diagonally arranged on the second bearing base;
[0031] There are two second positioning holes on the qualified irregular fin to be tested. The positions of the two second positioning posts match the positions of the two second positioning holes, and the relative positions of the two second positioning posts and the second irregular block match the relative positions of the two second positioning holes and the second irregular hole.
[0032] There are two third positioning posts, which are diagonally arranged on the third bearing base.
[0033] There are two third positioning holes on the qualified irregular fin to be tested. The positions of the two third positioning posts match the positions of the two third positioning holes, and the relative positions of the two third positioning posts and the third irregular block match the relative positions of the two third positioning holes and the third irregular hole.
[0034] In the implementation of the above technical solution, the limitation on the number and setting position of the second and third positioning posts can make the irregular fins to be inspected more stable and avoid shaking, which would affect the inspection. Furthermore, the matching limitation of the relative positions can make the second and third irregular fin inspection fixtures have extremely high accuracy in inspecting the second and third irregular holes on the irregular fins to be inspected, and can effectively eliminate some judgment errors caused by positional offset.
[0035] In a preferred embodiment of this application, the second positioning post and the second bearing base are integrally formed; the third positioning post and the third bearing base are integrally formed.
[0036] In the implementation of the above technical solution, the second positioning column and the second bearing base adopt an integral molding structure, and the third positioning column and the third bearing base adopt an integral molding structure, which can facilitate the production and manufacturing of the second and third irregular-shaped inspection fixtures and reduce the production and manufacturing costs of the second and third irregular-shaped inspection fixtures.
[0037] This application discloses a tooling for inspecting irregularly shaped fins, which, compared with the prior art, has at least the following advantages:
[0038] The irregular fin inspection fixture of this application includes a first irregular fin inspection fixture, which includes a first support base and a first irregular block. The first irregular block is disposed on the first support base, and the shape and size of the first irregular block match the first irregular hole on the qualified irregular fin to be inspected. The first irregular fin inspection fixture is used to inspect the first irregular hole on the irregular fin to be inspected. That is, the operator can use the first irregular fin inspection fixture to identify and verify whether there are errors in the first irregular hole on the irregular fin to be inspected, so as to determine whether the irregular mold used to produce the irregular fin to be inspected is used correctly. Specifically, during inspection, the first irregular hole on the irregular fin to be inspected is aligned with the first irregular block of the first irregular fin inspection fixture, and the irregular fin to be inspected is placed on the first support base. The irregularly shaped fin to be inspected can be placed on the first supporting base. If the first irregularly shaped hole on the fin to be inspected matches the first irregularly shaped block perfectly, it indicates that the first irregularly shaped hole of the fin to be inspected is correct and the corresponding irregularly shaped mold is used correctly. If the situation is different during inspection, it indicates that the first irregularly shaped hole of the fin to be inspected is incorrect and the corresponding irregularly shaped mold is used incorrectly. Compared with the method of visual inspection by workers, this method can objectively and accurately identify and calibrate whether there are errors in the irregularly shaped holes of the produced fins. Moreover, it is extremely easy to use and can effectively improve the inspection efficiency of the produced fins. At the same time, if the irregularly shaped mold is found to be used incorrectly, it can be replaced in time to avoid continuous production of errors and reduce production costs.

Detailed Implementation
[0048] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0049] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.
[0050] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
[0051] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or a point connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
[0052] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.
[0053] The shaped molds used to produce irregularly shaped fins typically correspond to a single type of irregularly shaped hole on the fin. A single mold cannot produce multiple different shaped holes. Currently, there are many types of irregularly shaped fins, and the irregularly shaped holes often share similarities. The diversity of hole shapes and numbers, as well as the borrowing of different irregularly shaped parts, increases the difficulty of controlling the production of irregularly shaped fins. This can easily lead to the use of incorrect molds, resulting in incorrect holes on the produced fins, causing issues such as the heat exchanger being unable to bend or assembly abnormalities. To reduce this, workers visually inspect and verify the irregularly shaped holes during production. However, this visual inspection method relies heavily on the worker's experience, is subjective, and is prone to errors.
[0054] To address the problems in the prior art, this application provides a non-standard fin inspection fixture, which can be used to identify and correct the non-standard holes of the produced non-standard fins. Compared with the method of visual inspection by workers, it can objectively and accurately identify and correct whether there are errors in the non-standard holes of the produced non-standard fins. Moreover, it is extremely easy to use and can effectively improve the inspection efficiency of the produced non-standard fins.
[0055] Example 1
[0056] See Figures 1 to 3 ,in, Figure 2 and Figure 3The irregular fin in the text refers to an irregular fin.
[0057] The irregular fin inspection fixture of this application includes a first irregular fin inspection fixture 11. The first irregular fin inspection fixture 11 includes a first support base 111 and a first irregular block 112. The first irregular block 112 is disposed on the first support base 111, and the shape and size of the first irregular block 112 match the first irregular hole 21 on the qualified irregular fin 20 to be inspected.
[0058] In this embodiment, the first irregular block 112 is disposed on the upper surface of the first support base 111. For example, the upper surface of the first support base 111 is a plane. The size of the first irregular block 112 matches the first irregular hole 21 on the qualified irregular fin 20 to be tested, which means that the size of the first irregular block 112 matches the first irregular hole 21 on the qualified irregular fin 20 to be tested.
[0059] It should be noted that the first irregular block 112 does not necessarily refer to a single irregular block; the first irregular block 112 may contain one or more sub-irregular blocks. Similarly, the first irregular hole 21 on the irregular fin 20 to be tested does not necessarily refer to a single irregular hole; the first irregular hole 21 may contain one or more sub-irregular holes.
[0060] Understandably, a qualified non-standard fin 20 to be inspected can be a standard non-standard fin corresponding to the non-standard fin 20 to be inspected, or a non-standard fin that is manufactured in a qualified and correct manner corresponding to the non-standard fin 20 to be inspected. The non-standard holes of the non-standard fin 20 to be inspected may be incorrect or correct.
[0061] In this embodiment, the first irregular shape inspection fixture 11 is used to inspect the first irregular shape hole 21 on the irregular shape fin 20 to be inspected. That is, the operator can use the first irregular shape inspection fixture 11 to identify and correct whether there are errors in the first irregular shape hole 21 on the irregular shape fin 20 to be inspected, so as to determine whether the irregular shape mold used to produce the irregular shape fin 20 to be inspected is used correctly. Figure 3 As shown, Figure 3 The first irregular hole 21 on the irregular fin 20 to be inspected is the correct irregular hole, which is perfectly matched with the first irregular block 112 of the first irregular inspection fixture 11.
[0062] In this embodiment of the irregular fin inspection fixture, during inspection, the first irregular hole 21 on the irregular fin 20 to be inspected is aligned with the first irregular block 112 of the first irregular inspection fixture 11. The irregular fin 20 to be inspected is then placed on the first support base 111. If the irregular fin 20 to be inspected can be placed on the first support base 111, and the first irregular hole 21 on the irregular fin 20 to be inspected is completely matched with the first irregular block 112, it indicates that the first irregular hole 21 of the irregular fin 20 to be inspected is without problems, and the corresponding irregular mold is used correctly. If the situation is different during inspection, it indicates that the first irregular hole 21 of the irregular fin 20 to be inspected is incorrect, and the corresponding irregular mold is incorrect. Compared with the method of visual inspection by the staff, this method can objectively and accurately identify and calibrate whether there is an error in the irregular hole of the produced irregular fin. Moreover, it is extremely easy to use and can effectively improve the inspection efficiency of the produced irregular fin. At the same time, if the irregular mold is found to be used incorrectly, it can be replaced in time to avoid continuous production of errors and reduce production costs.
[0063] Preferably, the first irregular block 112 and the first bearing base 111 are integrally formed. The integrally formed structure can facilitate the production of the first irregular inspection fixture 11 and reduce the production cost of the first irregular inspection fixture 11.
[0064] For example, the material of the first irregular-shaped inspection fixture 11 can be the same as that of the irregular-shaped fin. For instance, the material of the first irregular-shaped inspection fixture 11 can be aluminum alloy. By using the same material as the irregular-shaped fin, the first irregular-shaped inspection fixture 11 can effectively prevent the irregular-shaped fin from generating debris due to friction between the first irregular-shaped inspection fixture 11 and the irregular-shaped fin during the inspection process, which would cause the irregular-shaped fin to undergo an "aluminum-copper infiltration" reaction when heated subsequently.
[0065] Example 2
[0066] See Figures 1 to 3 Based on the above embodiment one, the difference between this embodiment and embodiment one is that the irregular fin inspection fixture in this embodiment, the first irregular fin inspection fixture 11, further includes a first positioning post 113. The first positioning post 113 is disposed on the first bearing base 111, and the shape and size of the first positioning post 113 match the first positioning hole 22 on the qualified irregular fin 20 to be inspected.
[0067] Specifically, the first positioning post 113 is disposed on the upper surface of the first bearing base 111; the size of the first positioning post 113 matches the first positioning hole 22 on the qualified irregular fin 20 to be tested, which means that the size of the first positioning post 113 matches the first positioning hole 22 on the qualified irregular fin 20 to be tested.
[0068] In this embodiment, there are two first positioning posts 113, which are diagonally arranged on the first bearing base 111;
[0069] There are two first positioning holes 22 on the qualified irregular fin 20 to be tested. The positions of the two first positioning posts 113 match the positions of the two first positioning holes 22, and the relative positions of the two first positioning posts 113 and the first irregular block 112 match the relative positions of the two first positioning holes 22 and the first irregular hole 21.
[0070] In the above structure, the first positioning post 113 of the first irregular shape inspection fixture 11 can, during inspection, first position the irregular fin 20 to be inspected on the first bearing base 111, so that the irregular fin 20 to be inspected is placed on the first bearing base 111 by the first positioning post 113. Then, the first irregular shape block 112 identifies and calibrates the first irregular shape hole 21 on the irregular fin 20 to be inspected, and judges whether there are errors such as errors in the hole shape and position of the first irregular shape hole 21 on the irregular fin 20 to be inspected. The setting of the first positioning post 113 further improves the inspection efficiency. The accuracy of detecting the first irregular hole 21 on the irregular fin 20 is improved. Two first positioning posts 113 are diagonally arranged on the first bearing base 111. When the irregular fin 20 to be detected is placed on the first bearing base 111 through the first positioning posts 113, the irregular fin 20 to be detected is more stable and avoids shaking, which would affect the detection. Furthermore, the matching and limitation of the relative positions can make the first irregular detection fixture 11 have extremely high accuracy in detecting the first irregular hole 21 on the irregular fin 20 to be detected, and can effectively eliminate some judgment errors caused by positional deviation.
[0071] Preferably, the first irregular block 112, the first positioning post 113 and the first bearing base 111 are integrally formed.
[0072] Example 3
[0073] See Figures 1 to 7 Based on the above-described Embodiment 1 or Embodiment 2, the difference between this embodiment and Embodiment 1 or Embodiment 2 is that the irregular fin inspection fixture in this embodiment further includes a second irregular fin inspection fixture 12.
[0074] The second irregular shape inspection fixture 12 includes a second bearing base 121 and a second irregular shape block 122. The second irregular shape block 122 is disposed on the second bearing base 121, and the shape and size of the second irregular shape block 122 match the second irregular shape hole 23 on the qualified irregular shape fin 20 to be inspected.
[0075] The first irregular block 112 and the second irregular block 122 are different from each other, and the first irregular hole 21 and the second irregular hole 23 are different from each other.
[0076] In this embodiment, the second irregular block 122 is disposed on the upper surface of the second support base 121. For example, the upper surface of the second support base 121 is a plane. The size of the second irregular block 122 matches the second irregular hole 23 on the qualified irregular fin 20 to be tested, which means that the size of the second irregular block 122 matches the second irregular hole 23 on the qualified irregular fin 20 to be tested.
[0077] It should be noted that the second irregular block 122 does not necessarily refer to a single irregular block; the second irregular block 122 may contain one or more sub-irregular blocks. Similarly, the second irregular hole 23 on the irregular fin 20 to be tested does not necessarily refer to a single irregular hole; the second irregular hole 23 may contain one or more sub-irregular holes.
[0078] The first irregular block 112 and the second irregular block 122 are different from each other, which can mean that at least one of the shapes, sizes and positions of the first irregular block 112 and the second irregular block 122 are different from each other; the first irregular hole 21 and the second irregular hole 23 are different from each other, which can mean that at least one of the shapes, sizes and positions of the first irregular hole 21 and the second irregular hole 23 are different from each other.
[0079] In the above structure, the irregular fin 20 to be inspected may have two types of irregular holes. The setting of the second irregular inspection fixture 12 can facilitate the staff to simultaneously inspect the irregular fin 20 with different hole types, thereby improving the inspection efficiency.
[0080] Preferably, the second irregular block 122 and the second bearing base 121 are integrally formed. The integrally formed structure can facilitate the production of the second irregular inspection fixture 12 and reduce the production cost of the second irregular inspection fixture 12.
[0081] For example, the material of the second irregular-shaped inspection fixture 12 can be the same as that of the irregular-shaped fin. For instance, the material of the second irregular-shaped inspection fixture 12 can be aluminum alloy. By using the same material as the irregular-shaped fin, the second irregular-shaped inspection fixture 12 can effectively prevent the irregular-shaped fin from generating debris due to friction between the second irregular-shaped inspection fixture 12 and the irregular-shaped fin during the inspection process, which would cause the irregular-shaped fin to undergo an "aluminum-copper infiltration" reaction when heated subsequently.
[0082] It is understood that the second irregular fin detection fixture 12 of the irregular fin detection fixture in this embodiment can also be a third irregular fin detection fixture 13 or a fourth irregular fin detection fixture (not shown in the figure). The second irregular block 122, the third irregular block 132 and the fourth irregular block are different from each other. Specifically, two appropriate irregular fin detection fixtures can be selected for detection according to the two types of irregular holes present in the irregular fin 20 to be detected.
[0083] Example 4
[0084] See Figures 1 to 6 Based on the above embodiment three, the difference between this embodiment and embodiment three is that the irregular fin inspection fixture 12 in this embodiment further includes a second positioning post 123. The second positioning post 123 is disposed on the second bearing base 121, and the shape and size of the second positioning post 123 match the second positioning hole 24 on the qualified irregular fin 20 to be inspected.
[0085] Specifically, the second positioning post 123 is disposed on the upper surface of the second bearing base 121; the size of the second positioning post 123 matches the second positioning hole 24 on the qualified irregular fin 20 to be tested, which means that the size of the second positioning post 123 matches the second positioning hole 24 on the qualified irregular fin 20 to be tested.
[0086] In this embodiment, there are two second positioning posts 123, which are diagonally arranged on the second bearing base 121;
[0087] There are two second positioning holes 24 on the qualified irregular fin 20 to be tested. The positions of the two second positioning posts 123 match the positions of the two second positioning holes 24, and the relative positions of the two second positioning posts 123 and the second irregular block 122 match the relative positions of the two second positioning holes 24 and the second irregular hole 23.
[0088] In the above structure, the second positioning post 123 can further improve the accuracy of detecting the second irregular hole 23 on the irregular fin 20 to be inspected. The limitation of the number and setting position of the second positioning post 123 can make the irregular fin 20 to be inspected more stable and avoid shaking, which would affect the inspection. In addition, the matching limitation of the relative position can make the second irregular inspection fixture 12 have extremely high accuracy in detecting the second irregular hole 23 on the irregular fin 20 to be inspected, and can effectively eliminate some judgment errors caused by positional offset.
[0089] Preferably, the second irregular block 122, the second positioning post 123 and the second bearing base 121 are integrally formed.
[0090] Example 5
[0091] See Figures 1 to 7 Based on the above embodiment three or four, the difference between this embodiment and embodiment three or four is that the irregular fin inspection fixture in this embodiment also includes a third irregular fin inspection fixture 13. The third irregular fin inspection fixture 13 includes a third bearing base 131 and a third irregular block 132. The third irregular block 132 is disposed on the third bearing base 131, and the shape and size of the third irregular block 132 match the third irregular hole (not shown in the figure) on the qualified irregular fin 20 to be inspected.
[0092] The first irregular block 112, the second irregular block 122 and the third irregular block 132 are different from each other, and the first irregular hole 21, the second irregular hole 23 and the third irregular hole are different from each other.
[0093] In this embodiment, the third irregular block 132 is disposed on the upper surface of the third bearing base 131. For example, the upper surface of the third bearing base 131 is a plane. The size of the third irregular block 132 matches the third irregular hole on the qualified irregular fin 20 to be tested, which means that the size of the third irregular block 132 matches the third irregular hole on the qualified irregular fin 20 to be tested.
[0094] It should be noted that the third irregular block 132 does not necessarily refer to a single irregular block; the third irregular block 132 may contain one or more sub-irregular blocks. Similarly, the third irregular hole on the irregular fin 20 to be tested does not necessarily refer to a single irregular hole; the third irregular hole may contain one or more sub-irregular holes.
[0095] The first irregular block 112, the second irregular block 122, and the third irregular block 132 are different from each other, which can mean that at least one of the shapes, sizes, and positions of the first irregular block 112, the second irregular block 122, and the third irregular block 132 are different from each other; the first irregular hole 21, the second irregular hole 23, and the third irregular hole are different from each other, which can mean that at least one of the shapes, sizes, and positions of the first irregular hole 21, the second irregular hole 23, and the third irregular hole are different from each other.
[0096] In the above structure, the irregular fin 20 to be inspected may have three types of irregular holes. The setting of the third irregular inspection fixture 13 can facilitate the staff to simultaneously inspect the irregular fin 20 with different types of irregular holes, thereby improving the inspection efficiency.
[0097] Preferably, the third irregular block 132 and the third bearing base 131 are integrally formed. The integrally formed structure can facilitate the production of the third irregular inspection tooling 13 and reduce the production cost of the third irregular inspection tooling 13.
[0098] For example, the material of the third irregular-shaped inspection fixture 13 can be the same as that of the irregular-shaped fin. For instance, the material of the third irregular-shaped inspection fixture 13 can be aluminum alloy. By using the same material as the irregular-shaped fin, the third irregular-shaped inspection fixture 13 can effectively prevent the irregular-shaped fin from generating debris due to friction between the third irregular-shaped inspection fixture 13 and the irregular-shaped fin during the inspection process, which would cause the irregular-shaped fin to undergo an "aluminum-copper infiltration" reaction when heated subsequently.
[0099] Example 6
[0100] See Figures 1 to 7 Based on the above embodiment five, the difference between this embodiment and embodiment five is that the irregular fin inspection fixture 13 of this embodiment also includes a third positioning post 133. The third positioning post 133 is disposed on the third bearing base 131, and the shape and size of the third positioning post 133 match the third positioning hole (not shown in the figure) on the qualified irregular fin 20 to be inspected.
[0101] Specifically, the third positioning post 133 is disposed on the upper surface of the third bearing base 131; the size of the third positioning post 133 matches the third positioning hole on the qualified irregular fin 20 to be tested, which means that the size of the third positioning post 133 matches the third positioning hole on the qualified irregular fin 20 to be tested.
[0102] In this embodiment, there are two third positioning posts 133, which are diagonally arranged on the third bearing base 131;
[0103] There are two third positioning holes on the qualified non-standard fin 20 to be tested. The positions of the two third positioning posts 133 match the positions of the two third positioning holes, and the relative positions of the two third positioning posts 133 and the third non-standard block 132 match the relative positions of the two third positioning holes and the third non-standard hole.
[0104] In the above structure, the third positioning post 133 can further improve the accuracy of detecting the third irregular hole on the irregular fin 20 to be inspected. The limitation of the number and setting position of the third positioning post 133 can make the irregular fin 20 to be inspected more stable and avoid shaking, which would affect the inspection. In addition, the matching limitation of the relative position can make the third irregular inspection fixture 13 have extremely high accuracy in detecting the third irregular hole on the irregular fin 20 to be inspected, and can effectively eliminate some judgment errors caused by positional offset.
[0105] Preferably, the third irregular block 132, the third positioning post 133 and the third bearing base 131 are integrally formed.
