Description

Technical Field

[0001] This utility model relates to the field of rotor deweighting technology, and in particular to rotor dynamic balancing inclined plane deweighting equipment. Background Technology

[0002] Due to material and manufacturing errors, motor rotors are always unbalanced, thus requiring dynamic balancing. Dynamic balancing typically involves removing weights or adding counterweights to the rotor to change its mass distribution. Currently, the removal of weights generally involves using a rotatable flat-jaw vise to clamp a V-block, rotating it to the required angle, and then placing it on a drilling machine for drilling. However, adjusting the angle and position is time-consuming, making it difficult to further improve the removal efficiency. In addition, the rotatable flat-jaw vise is relatively bulky, posing a safety hazard when installing it on or off the drilling machine. To address these shortcomings, this application is proposed.

The XY direction moving component is installed on the reference plate 21, and the V-block 26 is connected to the XY direction moving component. The V-block 26 is made of non-ferromagnetic material, preferably aluminum alloy.

[0026] V-block 26 can be configured in various ways depending on the rotor type. V-block 26 and XY axis moving assembly are preferably detachable and can be replaced with V-block 26 with different angles depending on the rotor model.

[0027] The XY-direction moving assembly includes a first slide rail 22 mounted on a reference plate 21, an X-direction slider 23 mounted on the first slide rail 22, a second slide rail 24 mounted on the X-direction slider 23, and a Y-direction slider 25 mounted on the second slide rail 24; a V-block 26 is mounted on the Y-direction slider 25, and the V-block 26 can be fixed or movable for fine adjustment after installation.

[0028] The V-block 26 is provided with a rotor placement groove 261 and a support slider 28, such as Figure 2 The V-block 26 is equipped with a third slide rail 262, and the rotor placement groove 261 is set between the third slide rails 262. It can be understood that a V-shaped groove is opened on the top surface of the third slide rail 262, and the support slider 28 is installed on the third slide rail 262 to improve the overall compactness of the structure.

[0029] The rotor placement groove 261 is a V-shaped groove and is inclined.
