Detailed implementation manners

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Embodiment 1: Please refer to Figures 1-3 , Figures 7-9 , for the existing detection device for turbine housings, when performing air pressure detection on the turbine housing, it is not convenient to rotate the air pressure detection sensor to make the detection more comprehensive. To solve this technical problem, the following technical content is disclosed in this embodiment;

[0036] A T-shaped plate 21 is slidably connected in a third storage groove 19 opened at the right end of the upper surface of the operating table 1, and a moving plate 20 is fixedly connected to the upper surface of the T-shaped plate 21. A stabilizing bolt 22 is threadedly connected to the middle of the front end of the T-shaped plate 21. A long slot 23 is opened at the front side of the right end of the upper surface of the operating table 1. An annular protrusion 26 fixedly connected to the middle of the lower surface of a second sealing plug 25 is engaged with an annular groove 24 opened in the middle of the upper surface of the moving plate 20. And a motor 27 is arranged in the middle of the upper end of the second sealing plug 25, and an output shaft of the motor 27 is fixedly connected with a turntable 28, and a pneumatic pressure detection sensor 29 is fixedly connected to the outer end of the upper surface of the turntable 28;

[0037] After the turbine housing is fixed on the operating table 1, the airtightness of the turbine housing is detected. When the turbine housing is fixed on the operating table 1, the bottom opening at the right end of the turbine housing is already connected to the second sealing plug 25. At this time, the first sealing plug 13 and the third sealing plug 38 are connected to other openings of the turbine housing through the first automatic telescopic rod 10 and the third automatic telescopic rod 32. After the openings are connected together, the air inflation pump 39 is started, and the turbine housing is inflated through the air inflation pump 39 to detect the airtightness of the turbine housing. Then the motor 27 is started, and the output shaft of the motor 27 drives the turntable 28 and the pneumatic pressure detection sensor 29 to rotate. Since the pneumatic pressure detection sensor 29 is installed at the outer end of the turntable 28, the pneumatic pressure detection sensor 29 can rotate around the inner side of the bottom opening of the turbine housing for one circle to detect whether there is any air leakage at the bottom of the opening of the turbine housing;

[0038] The second sealing plug 25 is connected to the annular groove 24 opened on the moving plate 20 by the annular protrusion 26 at the bottom, and the second sealing plug 25 can be pulled out upward from the moving plate 20. When installing the turbine housing, the motor 27 is placed in the groove opened in the middle of the upper surface of the second sealing plug 25. It is necessary to move the moving plate 20 left and right. According to the position of the right end of the turbine housing, the position of the moving plate 20 is adjusted. When adjusting the position of the moving plate 20, the T-shaped plate 21 slides in the third storage groove 19. After determining the position of the moving plate 20, tighten the stabilizing bolt 22 so that the moving plate 20 can be fixed at a certain position in the third storage groove 19;

[0039] Embodiment 2: For the existing detection device for turbine housings, turbine housings have different models and sizes. When detecting a turbine housing, it is not convenient to fix turbine housings of different models and sizes, and the sealing plugs for detecting the sealing performance of swimsuits are not convenient to be replaced according to the models of different turbine housings. Therefore, the following technical solutions are adopted in this embodiment, as Figures 1-9 shown;

[0040] At the upper and lower ends of the front side of the operating table 1, first storage grooves 2 are provided, and a number of sliding doors 3 are slidably connected in the first storage grooves 2. A number of first through holes 4 are provided at the left end of the top surface of the operating table 1, and a storage box 5 is fixedly connected to the lower surface of the left end of the top surface of the operating table 1 by a number of bolts. The fixing mechanism is composed of a first hydraulic rod 6, a limiting rod 7, a lifting platform 8, a support column 9, a first automatic telescopic rod 10, a first connecting plate 11, a second storage groove 12, a first sealing plug 13, a T-shaped block 14, a storage table 15, a second automatic telescopic rod 16, a clamping plate 17 and a protective pad 18. The first hydraulic rod 6 is fixedly connected to the middle of the inner bottom surface of the storage box 5, and limiting rods 7 are arranged on both the front and rear sides of the first hydraulic rod 6, and the upper and lower ends of the limiting rod 7 are respectively fixedly connected to the lower surface of the bottom of the operating table 1 and the inner lower surface of the storage box 5. The output end of the first hydraulic rod 6 is fixedly connected to a lifting platform 8, and the lifting platform 8 is connected through the limiting rod 7, and the middle of the left end of the upper surface of the lifting platform 8 is fixedly connected to a support column 9. The columns at the front and rear ends on the right side of the upper surfaces of the support column 9 and the lifting platform 8 are slidably connected in the first through hole 4, and the top end of the support column 9 is fixedly connected to a first automatic telescopic rod 10, and the output end of the first automatic telescopic rod 10 is fixedly connected to a first connecting plate 11. A second storage groove 12 is provided in the middle of the upper right end of the first connecting plate 11, and a T-shaped block 14 fixedly connected to the middle of the left side of the first sealing plug 13 is slidably connected in the second storage groove 12. A storage table 15 is arranged at the upper right end above the lifting platform 8, and the storage table 15 is fixedly connected to the left end of the upper surface of the operating table 1. Second automatic telescopic rods 16 are fixedly connected to the front and rear sides of the top of the right end of the lifting platform 8, and the output ends of the second automatic telescopic rods 16 are fixedly connected to a clamping plate 17, and a protective pad 18 is fixedly connected to the inner side surface of the clamping plate 17;

[0041] By pushing and pulling the sliding door 3, the front side of the operating table 1 can be opened to maintain the components inside the operating table 1. When placing the turbine housing, place the left end of the turbine housing on the storage table 15, and then start the first hydraulic rod 6 to make the lifting platform 8 drive the support column 9 and the components at the right end of the lifting platform 8 to move up and down inside the operating table 1 and the storage box 5. When the lifting platform 8 moves up and down, the limiting rod 7 provides limiting support for the lifting platform 8. Adjust the positions of the first sealing plug 13 and the clamping plate 17 according to the height of the left end of the turbine housing. After adjusting the heights of the first sealing plug 13 and the clamping plate 17, start the second automatic telescopic rod 16. The output end of the second automatic telescopic rod 16 drives the clamping plate 17 to move inward until the inner side of the protective pad 18 on the inner side of the clamping plate 17 fits against the outer side of the left end of the turbine housing, clamping and fixing the left end of the turbine housing. Then start the first automatic telescopic rod 10. The output end of the first automatic telescopic rod 10 drives the first sealing plug 13 to move to the right, so that the first sealing plug 13 blocks the opening on the left side of the turbine housing, and the fixing of the turbine housing is completed. Since the T-shaped block 14 on the left side of the first sealing plug 13 is slidably connected to the second storage groove 12 opened on the right side of the first connecting plate 11, the first sealing plug 13 can be pulled out upward from the first connecting plate 11, and a suitable first sealing plug 13 can be replaced according to the model of the turbine housing, so as to fix turbine housings of different model sizes;

[0042] The detection mechanism is composed of a support rod 30, a top plate 31, a third automatic telescopic rod 32, a second connecting plate 33, a second through hole 34, a third connecting plate 35, a positioning column 36, a spring 37, a third sealing plug 38, an air pump 39 and an air guide pipe 40. A number of support rods 30 are fixedly connected to the outer side surface of the moving plate 20 at equal angles, and the middle part of the upper surface of the support rod 30 is fixedly connected with a top plate 31. And the middle part of the upper surface of the top plate 31 is fixedly connected with a third automatic telescopic rod 32. The output end of the third automatic telescopic rod 32 is fixedly connected with a second connecting plate 33. And a number of second through holes 34 are opened at equal angles at the outer end of the second connecting plate 33. And the positioning column 36 fixedly connected to the outer end of the upper surface of the third connecting plate 35 is slidably connected inside the second through hole 34. A spring 37 is arranged on the outer side of the positioning column 36 between the inner side surfaces of the second through hole 34 and the third connecting plate 35. The lower surface of the third connecting plate 35 is fixedly connected with a third sealing plug 38 by a number of bolts. The right end of the upper surface of the top plate 31 is fixedly connected with an air pump 39. And the output port of the air pump 39 is fixedly connected with an air guide pipe 40. And the bottom end of the air guide pipe 40 is connected through the middle parts of the second connecting plate 33, the third connecting plate 35 and the third sealing plug 38;

[0043] Since the top plate 31 is fixedly connected to the moving plate 20 by the support rod 30, when the moving plate 20 is moved, the top plate 31 and the components on the top plate 31 will move along with the moving plate 20. The third sealing plug 38 is driven by the output end of the third automatic telescopic rod 32 to move, so as to seal the opening at the top of the right end of the turbine housing. When the third sealing plug 38 is moved, when the third sealing plug 38 contacts the turbine housing, the third sealing plug 38 will be buffered by the spring 37, and the positioning column 36 on the spring 37 will slide in the second through hole 34 opened on the second connecting plate 33, preventing the third automatic telescopic rod 32 from driving the third sealing plug 38 with excessive pressure and causing damage to the turbine housing. After that, the turbine housing can be inflated to detect the sealing performance of the turbine housing;

[0044] The standard parts used in the present invention can all be purchased from the market. The special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt the mature conventional means such as bolts, rivets, and welding in the prior art.

[0045] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
