Description

Technical Field

[0001] The utility model relates to the technical field of rotor stress relief, in particular to a protective tooling for rotor stress relief equipment. Background Art

[0002] In recent years, with the rapid development of the new energy vehicle industry, the requirements for motor rotors are also constantly increasing. In particular, during the preparation of motors with speeds of 16,000 r / min to 18,000 r / min or even higher, the rotor needs to be tested for high-speed rotation. After the rotor assembly is assembled and installed, the internal stress of the rotor is not completely released. When it is put on the dynamic balancing machine for high-speed operation for the first time, the dynamic balance state of the rotor will be destroyed, and its imbalance will produce high-frequency vibration, which will affect the motor. The rotor can undergo a certain amount of plastic deformation under the action of relatively large centrifugal force through high-speed rotation testing, so that the rotor can fully release the internal stress, and then when the rotor runs to this speed again, its imbalance will not change significantly, thereby extending its service life and reducing the motor failure rate.

[0003] At such high speeds, the rotor may not only undergo significant physical deformation and dimensional changes, but there is also a risk that the rotor may splash debris or derail during high-speed rotation. This will not only seriously affect the normal operation of the motor, but also cause a significant decline in the performance and reliability of the rotor, and even cause production accidents.

[0006] Furthermore, the upper and lower ends of the protective cover are open ends, and the protective cover can move in the vertical direction relative to the rotating rotor.

[0007] Preferably, the shield assembly also includes: a linear guide rail arranged on the side of the bracket, the length direction of the linear guide rail is the vertical direction, and the shield is connected to the linear guide rail; a lifting cylinder arranged on the side of the bracket, the extension and contraction direction of the lifting cylinder is the same as the length direction of the linear guide rail, and the lifting cylinder drives the shield to move along the linear guide rail.

[0008] Preferably, the shield assembly also includes: a stop pin arranged at the top end of the linear guide rail, which can limit the movement of the shield toward the top end of the linear guide rail; a buffer arranged at the top end of the linear guide rail, which forms a structure for absorbing the impact energy of the upward movement of the shield; a limit switch arranged at the bottom end of the linear guide rail, which can constrain the shield from moving toward the bottom end of the linear guide rail; the travel of the shield is from the bottom end of the linear guide rail to the top end of the linear guide rail.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] In the description of the embodiments of the present invention, it should be noted that the terms "inside", "outside", "upper", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the product of the present invention is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the present invention.

[0018] like Figure 1 As shown, this embodiment includes: a welding body 1, which includes a vertically mounted bracket 12; and a shield assembly 2 arranged on the side of the bracket 12, the shield assembly 2 includes a protective cover 23, the interior of the protective cover 23 forms a cavity for placing a rotating rotor, and the projection of the protective cover 23 on the side of the bracket 12 can completely cover the rotating rotor.

[0019] Specifically, the bracket 12 is a vertically mounted plate, one side of which is a vertical surface, which is connected to the shield assembly 2 and the platform for fixing the rotor by bolts, wherein the axial direction of the rotor is the vertical direction; secondly, the shield assembly 2 is used to intercept debris splashed out by the rotor during rotation or to intercept a derailed rotor, wherein the protective cover 23 is a cavity surrounded by side plates for placing the rotor, and the projection direction of the protective cover 23 is perpendicular to the axial direction of the rotor, so that the interception direction of the side plates of the protective cover 23 is perpendicular to the axial direction of the rotor, that is, perpendicular to the side of the bracket 12, wherein the debris splashing direction of the rotor is perpendicular to its axial direction, so that the interception direction of the protective cover 23 and the debris splashing direction of the rotor are both on the horizontal plane, and when the projection of the protective cover 23 along the interception direction can cover the rotor, the protective cover 23 can intercept all debris splashed out of the rotor, and can even intercept a derailed rotor, thereby improving the protection capability of the protective cover 23.

[0020] Furthermore, the upper and lower ends of the protective cover 23 are open ends, and the protective cover 23 can move in the vertical direction relative to the rotating rotor.

[0021] Specifically, the protective cover 23 is composed of side plates, and its cross-section is U-shaped, so that when the protective cover 23 moves in the vertical direction, it will never interfere with the rotor. The protective cover 23 can be separated from the rotor to facilitate the operator to remove the rotor, and the side plates of the protective cover 23 can be moved quickly to surround the rotor to intercept splashed debris, thereby improving work efficiency.

[0022] Furthermore, the shield assembly 2 also includes: a linear guide rail 21 arranged on the side of the bracket 12, the length direction of the linear guide rail 21 is the vertical direction, and the shield 23 is connected to the linear guide rail 21; a lifting cylinder 22 arranged on the side of the bracket 12, the extension and retraction direction of the lifting cylinder 22 is the same as the length direction of the linear guide rail 21, and the lifting cylinder 22 drives the shield 23 to move along the linear guide rail 21.

[0023] Specifically, the axial direction of the rotor is vertical, and the linear guide 21 is installed on the side of the bracket 12 by bolt connection, and its length direction is parallel to the axial direction of the rotor. The protective cover 23 is slidably connected to the linear guide 21 through a slider, so that when the lifting cylinder 22 drives the protective cover 23 to move up and down along the linear guide 21, the moving direction of the protective cover 23 is parallel to the axial direction of the rotor, so that the protective cover 23 will never interfere with the rotor during the movement, thereby ensuring its interception effect and ensuring safety during the processing.

[0024] like Figure 2 As shown, the shield assembly 2 also includes: a stop pin 25 arranged at the top end of the linear guide rail 21, which can limit the movement of the shield 23 toward the top end of the linear guide rail 21; a buffer 24 arranged at the top end of the linear guide rail 21, which forms a structure for absorbing the impact energy of the upward movement of the shield 23; a limit switch 28 arranged at the bottom end of the linear guide rail 21, which can constrain the shield 23 from moving toward the bottom end of the linear guide rail 21; the stroke of the shield 23 is from the bottom end of the linear guide rail 21 to the top end of the linear guide rail 21.

[0025] Specifically, a stop pin 25 and a buffer 24 are installed at the top of the linear guide 21, wherein the stop pin 25 is a cylinder and the buffer 24 is a compression spring. The bottom end face of the buffer 24 is closer to the protective cover 23 than the stop pin 25, so that the lifting cylinder 22 drives the protective cover 23 to move up to the end of the stroke and first contacts the buffer 24 to decelerate until the top end face of the protective cover 23 compresses the buffer 24 and contacts the stop pin 25. At this time, the speed is zero and the protective cover 23 reaches the end of the stroke. At this time, the projection of the protective cover 23 on the side of the bracket 12 does not intersect with the rotor. , which makes it easier for operators to remove or install the rotor and improves the convenience of installation; secondly, when the lifting cylinder 22 pushes the protective cover 23 down to the lower end of the stroke, the limit switch 28 fixedly installed at the bottom end of the linear guide 21 can detect the protective cover 23. At this time, the limit switch 28 controls the lifting cylinder 22 to stop extending and retracting, thereby limiting the movement of the protective cover 23. At this time, the speed of the protective cover 23 is zero, and the projection of the protective cover 23 on the side of the bracket 12 completely covers the rotor, which has an interception effect. Therefore, the protective cover 23 only moves between the top and bottom ends of the linear guide 21.

[0026] Furthermore, the protective cover assembly 2 also includes: an oil receiving box 26 arranged below the limit switch 28, the oil receiving box 26 forms a cavity, and the projection of the oil receiving box 26 in the vertical direction can cover the projection of the protective cover 23 in the vertical direction; and an oil drain ball valve 27 arranged at the lowest point of the oil receiving box 26.

[0027] Specifically, the rotor will drip lubricating oil during the rotation process, and the dripping lubricating oil can fall into the oil receiving box 26 to avoid dripping into other places and polluting the working environment. There is a lowest point at the bottom of the oil receiving box 26, so that the lubricating oil dripping therein can flow to the lowest point under the action of gravity and finally be released into the container for waste lubricating oil through the oil drain ball valve 27.

[0028] Furthermore, the welding fuselage 1 further includes: a base 11 supporting the bracket 12; and a shock absorbing pad 13 provided at the intersection of the bracket 12 and the base 11, the shock absorbing pad 13 forming a structure for absorbing vertical vibration.

[0029] Specifically, the bracket 12 is connected to the base 11 by bolts, but there is a gap between the bottom surface of the bracket 12 and the top surface of the base 11, and a shock-absorbing pad 13 is placed in the gap. The shock-absorbing pad 13 is made of a material that elastically deforms under pressure, such as a rubber pad. The axial height of the shock-absorbing pad 13 is not less than the height of the gap, so that the shock-absorbing pad 13 can provide support for the bracket 12, and the vibration generated when the rotor rotates can be transmitted to the shock-absorbing pad 13 through the support. The shock-absorbing pad 13 absorbs vibration energy through elastic deformation, thereby alleviating the overall vibration of the embodiment, reducing the friction between parts caused by vibration and reducing service life, and reducing noise during operation.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
