[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0022] Please see Figure 1-3This utility model provides an implementation scheme: At present, the sealing test of turbine housing mainly involves installing sealing plugs on multiple air ports, pumping high-pressure gas into one side, and judging the sealing performance by observing the pressure gauge. At present, sealing plugs are mostly used to seal the air ports. However, these sealing plugs are mainly installed on the air ports in a blocking manner, which has the problems of not being able to flexibly change the position of the pressure gauge and being prone to leakage.

[0023] To address the aforementioned issues, this application discloses a turbine housing machining inspection structure, comprising an inspection base 1, a limiting block 2 coaxially disposed on one side of the inspection base 1, and an inspection connecting seat 3 coaxially disposed on one side of the inspection base 1 and the limiting block 2. The inspection base 1 serves as the main mounting body for the inspection structure. During use, a corresponding number of inspection mechanisms are configured according to the number of air ports on the turbine housing. During the sealing test, an air pump needs to be connected to the inspection base 1 on at least one air port, and a pressure gauge 8 is provided on the inspection base 1 corresponding to at least one air port. During the sealing test, the inspection base 1 is fixed to the air port to improve the versatility of other accessories besides the necessary external auxiliary equipment such as the pressure gauge 8 and the air pump.

[0024] During testing, the limiting plug 2 of the testing connector 3 is inserted with one side facing the air port, and the limiting plug 2 and the air port are sealed. Then, a testing groove 4 is set in the middle of the testing connector 3, which extends to one side of the testing base 1. The testing connector 3 serves as the main body for connecting external equipment. A rotary sealing valve 5 is set on the testing connector 3. The rotary sealing valve 5 can play a sealing role by moving and cooperating with the testing connector 3. When the testing base 1 is not performing air pressure testing, the rotary sealing valve 5 is used to seal the testing connector 3 to prevent air pressure leakage. When connecting the air pump and the pressure gauge 8, the rotary sealing valve 5 on the testing connector 3 is opened.

[0025] Furthermore, the limiting plug 2 is a ring-shaped plate that matches the diameter of the air port. The limiting plug 2 is made of soft rubber and has an interference fit with the air port. When the limiting plug 2 is inserted into the air port, it plays a sealing role, ensuring the tightness of the connection.

[0026] Furthermore, in order to facilitate the use of pressure gauge 8, the detection groove 4 passes through one side of the head end of the detection connecting seat 3. The detection connecting seat 3 is provided with a connecting thread head 6, and a detection rod 7 is threadedly connected to the connecting thread head 6. The head end of the detection rod 7 is provided with pressure gauge 8. The detection rod 7 has a hollow structure and a threaded structure at the end. When the detection rod 7 is inserted into the connecting thread head 6, a tight connection between the connecting thread head 6 and the detection rod 7 is achieved.

[0027] Furthermore, to facilitate the use of the air pump, a pressure fitting 9 is threaded onto the connecting threaded head 6. An air pumping pipe 10 is connected to the tail end of the pressure fitting 9, and an air pump 11 is connected to the tail end of the air pumping pipe 10. The pressure pump pumps high-pressure air from the air pumping pipe 10 and the pressure fitting 9 into the connecting threaded head 6, thereby allowing the high-pressure air to enter the pump housing. The sealing performance of the volute is checked according to the reading of the pressure gauge 8 on the other air port.

[0028] To ensure the tightness of the installation of the detection base 1, at least two pairs of connection holes 12 are provided on the outside of the detection base 1. The connection holes 12 are connected by the holes on the air port flange. The screws in the connection holes 12 pass through the holes and are fixed to the air port by pulling back with nuts.

[0029] As a preferred option, the two pairs of connecting holes 12 are arranged in a ring array on the detection base 1, and two pairs of connecting screws are provided in the two pairs of connecting holes 12. The limiting and fixing function of the detection base 1 is achieved by the tensioning action between the connecting screws and the connecting holes 12.

[0030] As a preferred option, the limiting block 2 is a ring-shaped plate with an inwardly inclined slope on its outer side to facilitate insertion into the air port.

[0031] As a preferred option, the aforementioned detection connector 3 is further developed into a cylindrical plate, with the detection connector 3 and the detection base 1 integrally formed. The connecting thread head 6 is integrally formed with the detection connector 3, and the connecting thread head 6 has an internal thread structure. The threaded connector head and the detection connector 3 are connected by a tapered structure to increase the structural strength.

[0032] As a preferred option, the rotary closing valve 5 is further designed as a ball valve for easy operation.

[0033] As a preferred option, the detection base 1 is a rectangular plate.

[0034] In summary, the turbine housing machining and inspection structure uses the inspection base 1, the limiting block 2, and the inspection connecting seat 3 as the main body for sealing inspection. During the sealing inspection of the turbine housing, different inspection bases 1 are used to seal different air ports on the turbine housing. Then, different inspection bases 1 are used to perform sealing operations and connect pressure gauges and air pumps, which can ensure the sealing and accuracy of the inspection, while also facilitating disassembly and use.
