[0002] Rectifiers are widely used in various occasions where the fluid flow state needs to be optimized, such as gas ultrasonic flowmeters, turbine engines, wind turbines, etc. Rectifiers can improve the fluid flow state, improve the measurement accuracy and stability of flowmeters. In turbine engines and wind turbines, the rectifier blades can also ensure that the air flow smoothly flows along the surface of the engine or generator blades, reduce the formation of eddies and turbulence, reduce the vibration and noise of the equipment, and improve the working efficiency and power generation efficiency of the equipment. Rectifiers usually need to be processed on both sides, but for the existing rectifier processing positioning devices, the steps of repeatedly positioning the rectifier are cumbersome, and the positioning device blocks a lot during the blade processing, with low practical efficiency, which is not conducive to improving the processing efficiency. Content of the Utility Model

[0003] Aiming at the disadvantages of the existing rectifier processing positioning devices, that is, the steps of repeatedly positioning the rectifier are cumbersome, and there are many blockages during the processing of the blades on the processed surface after positioning, with low practical efficiency and not conducive to improving the processing efficiency, the utility model provides a double-sided switching processing tool for a rectifier, which is relatively simple in repeatedly positioning the rectifier, has less blockage to the blades on the processed surface after positioning, has high practical efficiency, and is conducive to improving the processing efficiency.

[0004] The utility model provides the following technical solutions:

[0005] It includes a master disk and a positioning sub-disk. The overall longitudinal cross-sectional view of the positioning sub-disk is in a cross shape. The rod part of the cross-shaped positioning sub-disk is connected to the master disk by a zero-point positioning structure. It is characterized in that: the outer edge of the upper half of the rectifier is sleeved with the horizontal root part of the cross-shaped positioning sub-disk, the bottom plate of the rectifier and the outer peripheral surface of the bottom plate are limited by an adjustable floating pressing seat structure, the inner peripheral surface of the bottom plate of the rectifier is sleeved with a pressing sub-disk, and the pressing sub-disk and the positioning sub-disk are connected by screws.

[0006] It is further characterized in that:

[0007] The adjustable floating pressing seat structure includes a cylinder. A fixed table is installed on the piston rod of the cylinder. A pressing seat is installed on the upper part of the fixed table. A pressing block is rotatably installed at the protruding part of the pressing seat. A locking pressure bolt is installed through the middle part of the pressing block. The bolt head of the locking pressure bolt passes through the pressing block and is inserted into the pressing seat;

[0008] The zero-point positioning structure includes a zero-point pull stud. The zero-point pull stud passes through the positioning sub-disk and is connected to the zero-point positioner installed on the mother disk. Around the zero-point pull stud, the positioning sub-disk is provided with guiding pins penetrating therethrough. The guiding pins respectively match the guiding pin positioners, and the guiding pin positioners are arranged on the mother disk.

[0009] In the above technical solution, the technical effects and advantages provided by the present utility model are as follows:

[0010] After installing the rectifier in the positioning sub-disk through the pressing sub-disk to form an integral body, the outer ring edge of the rectifier is fixed through the adjustable floating pressing seat structure. This not only simplifies the positioning step, but also, due to the fitting relationship between the sub-disk and the rectifier, does not form a machining obstruction to the blades on the surface of the rectifier, with relatively high practical efficiency and being beneficial to improving the machining efficiency.

[0011] The arrangement of the guiding pin positioner and the guiding pin is used for pre-guiding before clamping. The guiding pin can prevent the problem of angular misinstallation and enhance the positioning accuracy of the device.

[0012] The cooperative arrangement of the zero-point pull stud and the zero-point positioner increases the positioning strength and is convenient for disassembly, which is beneficial to operation and further improves the machining efficiency. Description of the Drawings

Subsequently, the guiding pin locator 15 is connected to the guiding pin 4 for rough positioning. Then, the zero-point locator 5 is connected to the zero-point pull stud 3. The rectifier 8, the sub-plate positioning seat 1, and the sub-plate pressing seat 2 will form an integral body and be locked on the master plate 7. Finally, the rectifier 8 is sequentially pressed through the adjustable floating pressing seat structure 6 to complete the positioning;

[0024] During turning over, the master plate 7 is ventilated. Subsequently, the locking state between the zero-point locator 5 and the zero-point pull stud 3 is disconnected. After removing the pressing sub-plate 2, the rectifier 8 is taken out and turned over. Repeating the installation steps can achieve double-sided switching positioning.
