Description

Technical Field

[0001] This utility model belongs to the field of mechanical equipment technology, specifically relating to a general tooling for processing the electronic rotor core rod of a hydro generator. Background Technology

[0002] As the core device of hydropower generation, the hydro-turbine generator plays a crucial role in the field of energy conversion. A hydro-turbine generator is a generator that uses a hydro-turbine as its prime mover to convert water energy into electrical energy.

[0003] Hydroelectric generators generate electricity by rotating the rotor and causing the magnetic poles to rotate. The yoke is mounted on the rotor, and the magnetic poles are suspended from the yoke by pole plates. The pole plates are fixed to the yoke using wedges, and a mandrel is used for positioning. The mandrel has bolt holes through which it is tightened. Since the assembled product can be up to 2 meters thick, the bolt holes must be highly perpendicular to the mounting surface. The flatness of the mounting surface significantly affects assembly accuracy. Due to length limitations, currently manufactured mandrels cannot meet the flatness requirements, and the mandrel's flatness will deform after machining the bolt holes.

[0004] To improve product precision and processing efficiency, this utility model designs a universal tooling for processing the electronic rotor core rod of a hydro generator, which meets customer requirements for precision and efficiency and satisfies market needs. Utility Model Content

One end of the drive rod passes through a fixed seat and is fixedly connected to a knob. A platform is located in the middle of the base plate, and the platform and fixed seats are on the same horizontal plane. A first support frame is mounted on the platform, with a first telescopic cylinder installed in the middle of the first support frame. A first pressure plate is fixedly connected to the telescopic end of the first telescopic cylinder.

[0008] Further, the two-way threaded section of each section of the driving rod is fixedly connected with a baffle at both ends.

[0009] Such a structure design can prevent the fixed block from moving out of the corresponding two-way threaded section of the driving rod by the baffle.

[0010] Further, the second support frame is fixedly connected to the fixed seat and is arranged in a U shape, a second telescopic cylinder is installed in the middle of the horizontal section of the second support frame, and a second pressing plate opposite to the fixed seat is fixedly connected to the telescopic end of the second telescopic cylinder.

[0011] Such a structure design can fix the upper side of the end of the core rod to be processed by the pressing plate, further enhancing stability.

[0012] Further, a plurality of arc-shaped limiting columns are arranged on the lower side of the first pressing plate, and each two arc-shaped limiting columns form a group, and one group of arc-shaped limiting columns corresponds to one group of fixed blocks.

[0013] Such a structure design can fix the middle part of the core rod by the arc-shaped limiting columns and the carrier plate, and only three contact fixing lines, small contact area, and strong stability.

[0014] Further, an avoiding groove is arranged at the position of the fixed block corresponding to the second pressing plate.

[0015] Such a structure design is convenient for the second pressing plate to further move downward, thereby pressing the core rod with a small diameter.
