Description

Technical Field

[0001] This utility model relates to the field of die casting technology, and in particular to a deformation inspection tool for castings. Background Technology

[0002] Due to uneven wall thickness in different parts, diverse structures, and inconsistent mold and local temperatures during die casting, a die casting will inevitably deform after ejection. When the deformation exceeds a certain standard, the casting will be scrapped.

[0003] Because die casting is highly efficient, it can produce more than a thousand pieces a day. However, if the quality control of the castings cannot be detected and judged, scrap will be produced continuously. Deformation of the castings will lead to batch scrapping, causing huge losses to the company. Summary of the Invention

[0004] The purpose of this utility model is to provide a deformation inspection tool for castings, which solves the problem that when existing casting quality control cannot detect and judge the deformation, scrap will be produced continuously, and the deformation of castings will lead to batch scrapping, causing huge losses to enterprises.

[0005] To achieve the above objectives, this utility model employs a deformation inspection fixture for castings, comprising a fixture base plate, a coarse positioning rod, a first height positioning rod, a second height positioning rod, a third height positioning rod, a support member, and a go-no-go gauge. The fixture base plate has a sliding plane. The coarse positioning rod, the first height positioning rod, the second height positioning rod, and the third height positioning rod are all fixedly connected to the fixture base plate and are all located above the fixture base plate. The support member is fixedly connected to the fixture base plate and is located above the fixture base plate. The go-no-go gauge is slidably disposed above the fixture base plate.

[0006] The support member includes a contact post and a support plate. The support plate is fixedly connected to the base plate of the inspection fixture and is located above the base plate of the inspection fixture. The contact post is fixedly connected to the support plate and is located on the outer side wall of the support plate.

[0007] The no-go gauge includes a no-go gauge boss, a no-go gauge height post, and a no-go gauge base. The no-go gauge base is located above the inspection fixture base plate and slides on the surface of the inspection fixture base plate. The no-go gauge height post is connected to the no-go gauge base and is located above the no-go gauge base. The no-go gauge boss is connected to the no-go gauge height post and is located at the end of the no-go gauge height post away from the no-go gauge base. The no-go gauge boss has a stop surface and a go surface.

[0008] The deformation inspection tool for the casting also includes multiple lifting rings, all of which are fixedly connected to the base plate of the inspection tool and are located above the base plate of the inspection tool.

[0009] This utility model discloses a deformation inspection fixture for castings. The fixture base plate is a large flat plane with three height positioning points for the casting designed on the plane. These three height positioning points are a first height positioning rod, a second height positioning rod, and a third height positioning rod. The casting is placed on top of these three height positioning rods. To accurately install the casting, a coarse positioning rod corresponding to the casting is designed on the base plate. The through hole of the casting can rotate around this coarse positioning rod. Simultaneously, a support point is fixed on the fixture base plate. When the casting rotates to… When the casting stops at the reference point, the three height positioning points support the entire casting, with the large flat surface of the casting facing upwards. The reference point positions the casting on the fixture, and the no-go gauge can be manually moved and rotated around the plane of the fixture's base plate. The no-go gauge is used to determine whether the deformation of the casting is within the acceptable range. Production continues when the no-go gauge passes the test, and stops when it fails, preventing batch scrapping of castings. By adopting the above method, it is possible to quickly and accurately determine whether the deformation of castings in production exceeds the standard, prevent batch scrapping, and reduce the company's losses.

Detailed Implementation

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] Please see Figures 1-6 This utility model provides a deformation inspection tool for castings: it includes a tool base plate 6, a coarse positioning rod 3, a first height positioning rod 5, a second height positioning rod 7, a third height positioning rod 9, a support member 8, and a go gauge 4. The tool base plate 6 has a sliding plane 10. The coarse positioning rod 3, the first height positioning rod 5, the second height positioning rod 7, and the third height positioning rod 9 are all fixedly connected to the tool base plate 6 and are all located above the tool base plate 6. The support member 8 is fixedly connected to the tool base plate 6 and is located above the tool base plate 6. The go gauge 4 is slidably disposed above the tool base plate 6.

[0020] In this embodiment, the fixture base plate 6 is a large plane with three height positioning points for the casting 1. These three height positioning points are the first height positioning rod 5, the second height positioning rod 7, and the third height positioning rod 9. The casting 1 is placed on top of these three height positioning rods. To accurately install the casting 1, a coarse positioning rod 3 corresponding to the casting 1 is designed on the base plate. The through hole of the casting 1 can rotate around this coarse positioning rod 3. Simultaneously, a support point is fixed on the fixture base plate 6. When the casting 1 rotates to the support point... When the process stops, the three height positioning points support the entire casting 1, with the large flat surface of casting 1 facing upwards. The support 8 positions casting 1 on the inspection fixture, and the no-go gauge 4 can be manually moved and rotated around the plane of the inspection fixture base plate 6. The no-go gauge 4 is used to determine whether the deformation of casting 1 is within the acceptable range. When the no-go gauge 4 passes the inspection, production continues; when it fails, production stops, preventing batch scrapping of casting 1. By adopting the above method, it is possible to quickly and accurately determine whether the deformation of casting 1 in production exceeds the standard, preventing batch scrapping and reducing the company's losses.

[0021] Furthermore, the support member 8 includes a contact post 16 and a support plate 17. The support plate 17 is fixedly connected to the inspection fixture base plate 6 and is located above the inspection fixture base plate 6. The contact post 16 is fixedly connected to the support plate 17 and is located on the outer side wall of the support plate 17.

[0022] In this embodiment, the backing plate 17 is fixed on the fixture base, the contact post 16 is installed on the backing plate 17, and the contact post 16 positions the casting 1 on the fixture.

[0023] Furthermore, the no-go gauge 4 includes a no-go gauge boss 13, a no-go gauge height post 12, and a no-go gauge base 11. The no-go gauge base 11 is located above the inspection fixture base plate 6 and slides on the surface of the inspection fixture base plate 6. The no-go gauge height post 12 is connected to the no-go gauge base 11 and is located above the no-go gauge base 11. The no-go gauge boss 13 is connected to the no-go gauge height post 12 and is located at the end of the no-go gauge height post 12 away from the no-go gauge base 11. The no-go gauge boss 13 has a stop surface 14 and a through surface 15.

[0024] In this embodiment, the no-go gauge 4 can be manually moved and rotated around the plane of the inspection fixture base plate 6. The no-go gauge 4 includes a no-go gauge boss 13, a no-go gauge height post 12, and a no-go gauge base 11. The top of the no-go gauge 4 has a protruding no-go boss. The no-go boss has a stop surface 14 and a through surface 15 with a step difference. The through surface 15 on the no-go boss is higher than the large plane 2 of the casting, and the stop surface 14 on the no-go boss is lower than the large plane 2 of the casting. When the deformation of casting 1 exceeds the design value, and when the large plane 2 of the casting is partially warped upwards, the through surface 15 of the no-go gauge 4 will be blocked by the large plane 2 of the casting and production must be stopped. Similarly, when the large plane 2 of the casting is partially warped downwards, the stop surface 14 of the no-go gauge 4 will pass through the large plane 2 of the casting. Only when the through surface 15 of the no-go gauge 4 passes through at that location and the stop surface 14 stops, it is determined that the deformation of casting 1 is within the acceptable range, casting 1 is qualified, and production can continue.

[0025] Furthermore, the deformation inspection tool for the casting also includes multiple lifting rings 18, all of which are fixedly connected to the base plate 6 of the inspection tool and are located above the base plate 6 of the inspection tool.

[0026] In this embodiment, by providing the lifting ring 18 above the base plate 6 of the inspection fixture, the base plate 6 of the inspection fixture can be moved easily using the lifting ring 18, making it convenient to use.

[0027] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
