Description

Technical Field

[0001] The invention belongs to the technical field of hydraulic turbines, and particularly relates to a multifunctional adjustable support tooling for a numerically controlled vertical lathe. Background Technique

[0002] A rotating assembly set composed of blades, a runner body and a drainage cone is an important mechanism of a hydraulic turbine. Its main function is to convert the kinetic energy of water flow into mechanical energy to provide power for the whole set of hydro-generators. In order to ensure that the hydraulic turbine has good hydraulic characteristics, the external dimensions of the blades in the runner assembly are crucial. Since the blades are large-area irregular curved surface structures, it brings great difficulties to the machining of the outer shape of the blade shoulders and the outer circle of the shaft end. If the workpiece size is too large, it is impossible to complete all in-plant machining with the existing tooling and machining capabilities in the workshop. Only the turning process can be outsourced. Therefore, a large amount of time and capital costs are increased.

[0003] To ensure the installation quality and construction period of the product, it is advisable to conduct trial assembly in the factory after each component of the rotating mechanism is manufactured. Since the rotating assembly is installed on the stay ring (an important basic embedded component of a hydraulic turbine), the trial assembly of this mechanism must be completed with the help of the stay ring. As a basic embedded part, the stay ring has been transported to the construction site and installed and the foundation has been poured according to the requirements of the power station civil engineering before each component of the rotating assembly is manufactured. Currently, there is a lack of tooling for trial assembly of the rotating assembly. Summary of the Invention

[0004] In view of this, the present invention aims to provide a multifunctional adjustable support tooling for a numerically controlled vertical lathe to solve the problem of the lack of tooling for trial assembly of the rotating assembly.

[0013] Multiple cross plates are also welded between the two side plates, and the width of the cross plates gradually decreases from bottom to top.

[0014] Furthermore, the top support connection component includes a support plate. The support plate is fixed to the top of the vertical support component by bolts. A connection disk is also installed on the upper surface of the support plate. The connection screw is installed on the upper surface of the connection disk through a mounting member.

[0015] Furthermore, the connection disk is a disk. Two arc-shaped holes are opened on the connection disk. Locking bolts are correspondingly arranged in the arc-shaped holes. The bottom of the locking bolt is fixedly connected to the support plate. The horizontal angle of the connection screw is adjusted by rotating the connection disk through the arc-shaped holes, and the adjusted connection disk is fixed by the locking bolt.

[0016] Furthermore, angle markings are engraved on the edge position of the upper surface of the connection disk, and reference lines are provided on the support plate. The rotation angle of the connection screw is obtained through the angle markings and the reference lines.
