Description

Technical Field

[0001] The utility model belongs to the technical field of turbine manufacturing and relates to a detection device for installing a snap ring of a turbine housing. Background Technique

[0002] A turbine is a rotary power machine that converts the energy of a flowing working fluid into mechanical work. It is one of the main components of aeroengines, gas turbines, and steam turbines.

[0003] During the assembly process of the turbine, a snap ring needs to be installed, and problems such as missing or under-installing the snap ring may occur during the installation process.

[0004] How to quickly detect the problem of missing or under-installing the snap ring during the assembly of the turbine housing. In the past, after installing the snap ring on the turbine housing, visual inspection was used to check whether the snap ring was missing or under-installed. When detecting the leakage amount during the subsequent assembly inspection, there was no anti-mistake measure for the snap ring, and all relied on the naked eye observation. Over time, it would cause visual fatigue and could not guarantee 100% whether the snap ring was assembled completely.

[0005] However, in actual assembly, if there is no effective anti-mistake measure in the subsequent process, it is very likely that the situation of missing or under-installing will occur, resulting in the inability to meet customer requirements. If it is not detected before shipment and flows to the customer, it will cause customer complaints. Summary of the Invention

[0024] Due to the drawing angle problem, some components may not be drawn, but their positions and connection relationships can be understood according to the text description part.

[0025] As Figure 1 shown, the present utility model is a turbine housing snap ring installation detection device, including a mounting plate 7, and a sensor lifting mechanism 1, a turbine housing positioning mechanism, and a turbine housing clamping mechanism are provided on the mounting plate 7.

[0026] As Figure 2 shown, the sensor lifting mechanism 1 includes a top plate 19 and a bottom plate 13 arranged up and down. The top plate 19 and the bottom plate 13 are connected by a column 12. A lifting shaft 16 is vertically slidably mounted on the top plate 19. A linear cylinder 15 is installed at the bottom of the top plate 19. The piston rod of the linear cylinder 15 is vertically downward and connected to a lifting bottom plate 24. The lifting bottom plate 24 is fixedly connected to the bottom of the lifting shaft 16. The top of the lifting shaft 16 extends out of the top plate 19 and a lifting top plate 22 is installed. The lifting top plate 22 is connected to a fiber optic sensor fixing seat 17 through a connecting plate group. A fiber optic sensor 18 is installed at the bottom of the fiber optic sensor fixing seat 17.

[0027] A flange linear bearing 21 is installed on the top plate 19, and the lifting shaft 16 slides in the flange linear bearing 21.

[0028] In order to protect the accuracy of the flange linear bearing 21 and the lifting shaft 16, a guide rod 14 is vertically installed on the bottom plate 13, and the lifting bottom plate moves up and down along the guide rod 14 to prevent the lifting shaft 16 from deflecting left and right.

[0029] The connecting plate group includes a first connecting plate 23 and a second connecting plate 20 which are connected.

[0030] The fiber optic sensors 18 are symmetrically installed at the bottom of the fiber optic sensor fixing seat 17. The monitoring area is between the two fiber optic sensors 18 on both sides.

[0031] AsFigure 3 As shown in the figure, the turbine housing positioning mechanism includes a turbine housing positioning plate 11, which is vertically arranged and installed on the vertical plate 25. A first positioning pin 9 and a second positioning pin 10 are horizontally installed on the turbine housing positioning plate 11.

[0032] In order to facilitate the operator to push the turbine housing 8 into the turbine housing positioning mechanism, a turbine bracket 6 is provided on one side of the vertical plate 25.

[0033] The turbine housing clamping mechanism includes a lever cylinder group, which is installed around the turbine housing positioning mechanism. The lever cylinder group is composed of a first lever cylinder 2, a second lever cylinder 3, a third lever cylinder 4, and a fourth lever cylinder 5. The cylinder bodies of the first lever cylinder 2, the second lever cylinder 3, the third lever cylinder 4, and the fourth lever cylinder 5 are fixedly installed on the vertical plate 25.

[0034] The working process of the present utility model is as follows:

[0035] As Figure 4 shown, the turbine housing 8 loaded with snap rings is first placed on the turbine bracket 6, and then pushed towards the turbine housing positioning plate 11, so that the first positioning pin 9 and the second positioning pin 10 are embedded in the turbine housing 8 to complete the positioning. The lever cylinder group acts to complete the pressing.

[0036] The linear cylinder 15 drives the fiber optic sensor 18 to descend into the turbine housing 8. If the turbine housing 8 is not installed or has fewer snap rings, when the receiving end sensor of the fiber optic sensor 18 detects the signal emitted by the transmitting end sensor of the fiber optic sensor 18, at this time, the receiving end of the fiber optic sensor 18 will feedback a signal and the device will immediately alarm, and the next step cannot be carried out. When two snap rings are correctly installed in the turbine housing 8, the signal emitted by the transmitting end sensor of the fiber optic sensor 18 is blocked by the snap rings, and the receiving end of the fiber optic sensor 18 cannot receive the signal emitted by the transmitting end, and the next step of detecting the leakage amount is carried out.

[0037] It can be understood that the above embodiments are merely exemplary embodiments adopted to illustrate the principle of the present utility model. However, the present utility model is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present utility model, and these modifications and improvements are also regarded as the protection scope of the present utility model.
