[0002] The turbine housing is formed by assembling molds for different parts, then pouring molten iron and allowing it to solidify. Due to the small size of the lettering modules, errors by workers during the mold assembly process can sometimes lead to omissions in the assembly. Relying solely on workers to ensure the integrity of the mold assembly is insufficient. Even if employees perform post-casting inspections, factors such as inattention and visual fatigue from prolonged work can cause defective products to reach the final product. Therefore, inspection devices are needed to prevent such situations. Summary of the Invention

Detailed Implementation
[0013] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0014] A device for detecting whether a lettering module is missing from a turbine housing casting mold, such as... Figure 1 and Figure 2 As shown, it includes a base plate 1, a workpiece reference hole support and positioning assembly 2, a workpiece air inlet flange support and positioning assembly 3, a workpiece air inlet flange clamping assembly 4, an infrared detector bracket 5, and an infrared detector 6.
[0015] On the upper surface of the base plate 1, there are a workpiece reference hole support and positioning assembly 2, a workpiece air inlet flange support and positioning assembly 3, a workpiece air inlet flange clamping assembly 4, and an infrared detector bracket 5. The workpiece reference hole support and positioning assembly 2 is used to support the end face of the workpiece reference hole and position the workpiece reference hole. The workpiece air inlet flange support and positioning assembly 3 is used to support the workpiece air inlet flange and position the end face of the workpiece air inlet flange. The workpiece air inlet flange clamping assembly 4 is used to clamp the workpiece air inlet flange onto the workpiece air inlet flange support and positioning assembly 3. An infrared detector 6 is fixed on the infrared detector bracket 5. The infrared detector 6 is used to detect whether the workpiece has excess casting material caused by missing casting module.
[0016] The workpiece reference hole support and positioning assembly 2 includes a workpiece reference hole mandrel base 21 and a workpiece reference hole mandrel 22 fixed on the upper surface of the workpiece reference hole mandrel base 21. The axis of the workpiece reference hole mandrel 22 is perpendicular to the upper surface of the workpiece reference hole mandrel base 21. The workpiece reference hole mandrel base 21 is used to support the end face of the workpiece reference hole, and the workpiece reference hole mandrel 22 is used to position the workpiece reference hole.
[0017] The workpiece air inlet flange support and positioning assembly 3 includes a support and positioning frame 31, a workpiece air inlet flange support seat 32 fixed on the support and positioning frame 31, and a workpiece air inlet flange positioning block 33; the workpiece air inlet flange support seat 32 is used to support the workpiece air inlet flange, and the workpiece air inlet flange positioning block 33 is used to position the end face of the workpiece air inlet flange.
[0018] The workpiece inlet flange clamping assembly 4 includes a cylinder mounting base 41, a cylinder 42, a support base 43, a pressure plate mounting base 44, a pressure plate 45, and a pressure head 46. The cylinder 42 and the support base 43 are both fixed to the cylinder mounting base 41. The pressure plate mounting base 44 is fixed on the support base 43. The middle part of the pressure plate 45 is hinged to the pressure plate mounting base 44 by a pin. One end of the pressure plate 45 is hinged to the piston rod end of the cylinder 42 by a pin. The other end of the pressure plate 45 is fixed with a pressure head 46. The pressure head 46 is used to press the workpiece inlet flange onto the workpiece inlet flange positioning block 33.
[0019] In use, the workpiece 7 (i.e., the turbine housing casting) is placed on the workpiece reference hole support and positioning assembly 2. The workpiece reference hole mandrel 22 is inserted into the workpiece reference hole, and the workpiece reference hole mandrel base 21 supports the end face of the workpiece reference hole. Due to its own weight, the workpiece 7 will remain horizontal. The workpiece air inlet flange is then placed into the workpiece air inlet flange support seat 32. Driven by the cylinder 42, the end face of the workpiece air inlet flange is pressed against the workpiece air inlet flange positioning block 33 by the pressure plate 45 and the pressure head 46, thereby fixing the workpiece 7. Then, the infrared detector 6 detects the casting area of the workpiece 7. If the casting module is not installed during the casting process, a raised fleshy area will form at the casting area of the workpiece 7, meaning that the infrared detector 6 can receive a reflected signal, indicating that the workpiece 7 is a defective product. Conversely, if the casting module has been installed during the casting of workpiece 7, the product part number will be formed at the casting location of workpiece 7. Since the product part number is lower than the casting material, the infrared detector 6 cannot receive a reflected signal, indicating that workpiece 7 is a qualified product.
[0020] The working principle of the infrared detector 6 is as follows:
[0021] Because the height of the part number casting is lower than the height of the succulent, the infrared beam of the infrared detector 6 is placed at a higher position. If a signal is received, there is succulent, and the product is unqualified. Conversely, if there is no succulent, the casting is normal, and the product is qualified. The detection accuracy can reach 100%.
[0022] During testing, this invention only requires completing the workpiece placement step, the cylinder clamping step, and the infrared detection step, which has the advantages of fast testing speed and high work efficiency. At the same time, this invention has the advantages of simple structure, easy production and assembly.
[0023] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
