Description

Technical Field

[0001] The utility model belongs to the technical field of generator bases, and particularly relates to a spring plate processing device. Background Art

[0002] On the generator base, to reduce the dual-frequency vibration caused by the magnetic pull of the rotor magnetic flux on the stator core, the generator stator core is mounted to the base via a spring plate to isolate the vibration. This spring plate is usually connected to a pad, which is connected between the partitions in the base, while the pad is connected to the outer wall of the core. To ensure the connection strength between the pad and the core, the pad's connection surface is usually machined into a curved surface corresponding to the outer wall of the core to increase the contact area and improve the reliability of the connection. At the same time, to ensure the consistency of the connection between the pad and the core, it is necessary to ensure that the pad's connection surface has a consistent curvature. Machining a single pad easily leads to errors and cannot ensure the consistency of the pad's connection surface.

[0003] Therefore, the above problems need to be solved urgently. Utility Model Content

[0004] Purpose of the Utility Model: To overcome the above shortcomings, the utility model provides a spring plate processing device that can ensure the uniform curvature of the connection surface between the pad and the iron core, increase the connection surface between the pad and the iron core, improve the connection firmness and reliability, avoid local stress concentration after installation, and improve the stability and durability of the entire machine base. At the same time, the uniform curvature of the pad connection surface makes it easier to install and fix the iron core, reducing the difficulty of iron core installation and facilitating subsequent maintenance.

[0005] Technical Solution: To achieve the above-mentioned objectives, the present invention provides a spring plate processing device, comprising a base plate, the top surface of which is connected to a mounting ring, the mounting ring being provided with a mounting surface, the mounting surface being provided on the outer side wall of the mounting ring. A pressing device is connected to the top surface of the mounting ring, the top surface of the base plate is connected to a second vertical plate, the second vertical plate and the mounting surface being arranged parallel to each other, a gap being left between the second vertical plate and the mounting surface, a spring plate being placed between the second vertical plate and the mounting surface, the spring plate being a square plate, the spring plate being installed against the mounting surface, a pad being connected to the side of the spring plate away from the second vertical plate, and the pressing device pressing the pad against the top surface of the mounting ring. The pressing device, the second vertical plate, and the mounting surface are arranged in an array along the mounting ring, and the pressing device and the second vertical plate are arranged correspondingly.

[0006] This device is a fixture for processing pads using a lathe, and it is necessary to first connect this device to the lathe workbench.

The spring plate is placed on the top surface of the base plate, the pad is placed on the top surface of the mounting ring, and the connected end of the spring plate and the pad is placed between the second vertical plate and the mounting surface, with the spring plate resting against the mounting surface. The clamping device presses the pad against the top surface of the mounting ring. The spring plate and the pad are arranged and pressed in sequence along the mounting ring, and finally the lathe is operated to process the pad connection surface. The utility model can process multiple pads at the same time during one clamping, ensuring the consistency of the curvature of the pad connection surface, increasing the connection surface between the pad and the iron core, improving the firmness and reliability of the connection, avoiding local stress concentration after installation, and improving the stability and durability of the entire machine base. The consistent curvature of the pad connection surface makes it easier to install and fix the iron core, reduces the difficulty of iron core installation, and improves maintenance convenience.

[0007] Furthermore, in the aforementioned spring plate processing device, a first vertical plate is connected to the top surface of the mounting ring. The first vertical plate is disposed at the end of the mounting surface away from the clamping device and is arranged along the mounting surface. The end of the spring plate away from the clamping device is connected to the first vertical plate. The provision of the first vertical plate and the connection between the spring plate and the first vertical plate improve the connection stability and the clamping accuracy.

[0008] Furthermore, in the above-mentioned spring plate processing device, the first vertical plate is provided with a first through hole, and the spring plate is provided with a through hole at one end away from the clamping device. The first through hole and the through hole are correspondingly arranged, and bolts are inserted into the first through hole and the through hole, and the bolts connect the spring plate and the first vertical plate.

[0009] Furthermore, in the aforementioned spring plate processing device, the clamping device includes a base block connected to the top surface of the mounting ring. A clamping block is provided on the top surface of the base block. The clamping block is rectangular and has waist holes along its long sides. Bolts pass through the waist holes and are screwed into threaded holes on the top surface of the base block. The top surface of the base block should be flush with the top surface of the cushion block. The cushion block is tightened and secured by bolts, resulting in a simple structure and easy operation.

[0010] Furthermore, in the above-mentioned spring plate processing device, in order to improve production efficiency, clamp and process multiple workpieces at a time, and ensure installation consistency, the mounting ring is set to be polygonal, and the straight side of the mounting ring is the mounting surface.

[0011] Furthermore, in the above-mentioned spring plate processing device, in order to improve the connection accuracy and strength between the spring plate and the pad, a convex ring is provided on the side of the pad close to the spring plate, and the spring plate is provided with a second through hole corresponding to the convex ring, and the convex ring extends into the second through hole.

[0012] Furthermore, in the above-mentioned spring plate processing device, in order to improve the positioning accuracy of the pad, the second vertical plate is provided with side top bolts, and there are 2 or more side top bolts, which are arranged around the convex ring and abut the convex ring. When clamping, the side top bolts are turned, and the side top bolts 52 squeeze the convex ring to press the spring plate against the installation surface, ensuring accurate clamping.

[0013] Furthermore, in the aforementioned spring plate processing device, to enhance the structural strength of the first and second risers, a first reinforcing rib is provided on the side of the first riser remote from the second riser, the first reinforcing ribs respectively connecting the first riser and the mounting ring. A second reinforcing rib is provided on the side of the second riser remote from the first riser, the second reinforcing ribs respectively connecting the second riser and the bottom plate.

[0014] As can be seen from the above technical solution, the present invention has the following beneficial effects: The present invention's spring plate processing device can simultaneously process multiple spacers in a single clamping operation, ensuring that the curvature of the connection surface between the spacers and the core is consistent, increasing the connection surface between the spacers and the core, improving the connection firmness and reliability, avoiding local stress concentration after installation, and improving the stability and durability of the entire machine base. The consistent curvature of the spacer connection surface makes it easier to install and secure the core, reducing installation difficulty and improving maintenance convenience.
