Problems solved by technology

Since there is no device to control the processing size and precision, the dimensional accuracy of the contact surface 311 will deviate after processing, and the processing quality of the contact surface 311 cannot be guaranteed.
If the size deviation of the contact surface 311 is too large, the local stress of the blade 30 will inevitably be too high, and the blade 30 will be easily damaged during operation.

Abstract

The invention discloses a grinding device of a blade damper platform. The blade damper platform is arranged on a blade. The grinding device comprises a base plate, a clamp and a feeding device, wherein the clamp is connected to the base plate and used for clamping the blade and enables the contact face of the blade damper platform to be parallel to a first direction, the feeding device is installed on the base plate and clamps a grinding tool, the feeding device can move in a second direction and the first direction so as to drive the grinding tool to grind the contact face of the blade damper platform, and the first direction and the second direction form an angle. According to the grinding device of the blade damper platform, the blade is located and fixed in the manner that the blade is clamped, the grinding tool is driven by the feeding device to conduct feeding, and then grinding of the contact face of the blade damper platform can be achieved; and in this way, locating can be well achieved, the machining dimension is accurately controlled, and the machining precision is guaranteed.

Description

technical field [0001] The invention relates to the technical field of grinding equipment, in particular to a grinding device for a blade damping table. Background technique [0002] In high-speed rotors, the damping table on the blade plays a very important role, which is used to transmit the circumferential force between the blades, increase the damping between the blades, and reduce the vibration of the blades. figure 1 The structure of a blade set with a damping table is shown. Depend on figure 1 As can be seen in the figure, each blade 30 is integrally formed with a blade damping platform 31 , and the blade damping platform 31 extends to both sides along a direction perpendicular to the blade 30 . The vane damping platform 31 forms a contact surface 311 on each side of the vane 30 , and the contact surfaces 311 of two adjacent vane damping platforms 31 are in contact. The blade damping table 31 of the adjacent blade must ensure a certain pressure to ensure frictional...
