Description

Technical Field

[0001] The present invention belongs to the technical field of rotor dynamic balancing equipment, and in particular relates to a rotor dynamic balancing brake tooling. Background Art

[0002] In rotating machinery such as motors, the rotor is the core component. In order to make the machine run smoothly at high speed, the rotor needs to be dynamically balanced.

[0003] In the prior art, when dynamically balancing the rotor, the operator hoists the rotor core on the dynamic balancing equipment. The dynamic balancing equipment includes a dynamic balancing bracket, a dynamic balancing drive motor installed on the dynamic balancing bracket, a dynamic balancing support roller installed on the top of the dynamic balancing bracket, and a dynamic balancing drive belt connected between the dynamic balancing drive motor and the rotor core. The rotor core is supported on the freely rotating dynamic balancing support roller by the rotor shaft thereon, and the rotor core rotates at high speed driven by the dynamic balancing drive belt. At this time, the high-speed rotating rotor core is dynamically balanced by the detection device of the dynamic balancing equipment, and the rotor core is stopped from rotating as needed, and the rotor core is dynamically balanced by adjusting the counterweight on the rotor core, and then the rotor core is rotated at high speed again to continue the dynamic balancing detection until the dynamic balancing detection passes.

[0004] During the dynamic balancing test, the rotor core needs to be stopped quickly to facilitate dynamic balancing. After the dynamic balancing is completed, the rotor core also needs to be stopped quickly to facilitate dynamic balancing of the next workpiece. Therefore, the rotating rotor core needs to be braked during the dynamic balancing of the rotor.

[0005] The current braking operation is to force the brake to stop by hand, and the operator uses both hands (wearing gloves) to directly contact the rotor core and press hard to brake. This existing operation has low braking efficiency and there are safety risks in using hand brakes to stop the vehicle. Utility Model Content

[0052] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present disclosure and its application or use. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0053] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present disclosure. As used herein, unless the context clearly indicates otherwise, the singular form is intended to include the plural form as well.

[0054] Figures 1 to 4 is a schematic diagram of the three-dimensional structure of the rotor dynamic balancing brake tooling according to an embodiment of the present disclosure observed from different viewing angles, Figure 5 yes Figure 1 The schematic diagram of the main structure of the working state of the rotor dynamic balancing brake tooling shown in the figure mainly shows the relative position relationship between the pressure arm, the brake pressure plate and the rotor core installed on the dynamic balancing device. Figure 6a and 6b yes Figure 1 The left-side structural schematic diagram of the rotor dynamic balancing brake tooling is shown, in which the pressure arm is in the pressure position and the fully open position respectively. Figure 7 is along Figure 6a The cross-sectional structure diagram of the MM line in FIG. 1 shows that the brake pressure plate is connected to the pressure arm through the pressure plate connecting assembly.

[0055] See also Figures 1 to 4 The rotor dynamic balancing brake tool 100 disclosed in the present invention is used to brake the rotor core C installed on the dynamic balancing device 200 after the rotor dynamic balancing is completed, and includes a tool support 11, a pressure arm connecting assembly 12, a pressure arm 13 installed on the tool support 11 through the pressure arm connecting assembly 12, a pressure plate connecting assembly 14, and a brake pressure plate 15 installed on the pressure arm 13 through the pressure plate connecting assembly 14.

[0056] from Figures 1 to 4 As can be seen in the figure, the tooling bracket 11 is arranged upright in the vertical direction, and is used to support the pressure arm 13 to a predetermined height position, so that the height of the brake pressure plate 15 on the pressure arm 13 is consistent with the height of the brake pressure plate 15 installed in the dynamic balancing device 200 (shown in FIG. Figure 5 The height of the rotor core C to be dynamically balanced is adapted to the height of the rotor core C to be dynamically balanced.

[0057] from Figures 1 to 4As can be seen in the figure, the pressure arm connection assembly 12 is fixedly mounted on the top of the tooling bracket 11. The pressure arm 13 has a base end and a free end, and the base end is connected to the pressure arm pivot (at Figure 1 , not labeled) can be pivotally connected to the pressure arm connection assembly 12 so that the pressure arm 13 is in the braking position (see Figure 6a ) and fully open position (see Figure 6b ) between the two.

[0058] The pressure plate connection assembly 14 is arranged in the middle of the pressure arm 13. The brake pressure plate 15 is installed below the pressure arm 13 through the pressure plate connection assembly 14. When the pressure arm 13 is pivoted to a predetermined braking position, the brake pressure plate 15 located below the pressure arm 13 contacts the rotor core C under the pressure of the pressure arm 13 to brake.

[0059] In the scheme disclosed in the present invention, a pivotable pressure arm 13 and a brake pressure plate 15 disposed on the pressure arm 13 are provided, and the brake pressure plate 15 can brake the rotor core C that needs to be dynamically balanced or is still in a rotating state after dynamic balancing is completed by operating the pressure arm 13. Compared with the existing operation of directly contacting the rotor core with both hands to brake, the scheme disclosed in the present invention has a fast braking speed, is convenient to operate and is safe.

[0060] In this embodiment of the present disclosure, by providing the pressure arm connecting assembly 12 , the pressure arm 13 can be conveniently pivotably connected to the tooling bracket 11 .

[0061] In this embodiment of the present disclosure, the brake pressure plate 15 can be conveniently connected to the pressure arm 13 by providing the pressure plate connecting assembly 14 .

[0062] Continue to see Figures 1 to 4 It can be seen that the pressure arm connection assembly 12 includes a mounting plate 121 and a mounting seat 122 mounted on the mounting plate 121. The mounting plate 121 is horizontally mounted on the top of the tooling bracket 11. The mounting seat 122 is a bent plate-like structure, including a horizontal plate portion 122a connected to the mounting plate 121 and two vertical plate portions 122b bent upward from both ends of the horizontal plate portion 122a. The base end of the pressure arm 13 is pivotally mounted on the two vertical plate portions 122b.

[0063] In this embodiment of the present disclosure, by adopting the mounting plate 121 and the mounting seat 122, the pressure arm 13 can be stably and reliably mounted on the tooling bracket 11, and it is easy to adapt to different tooling brackets 11, thereby improving the stability, convenience and adaptability of the entire brake tooling.

[0064] In this embodiment, the base end of the pressure arm 13 is indirectly pivotally connected to the tooling bracket 11 through an intermediate structure, for example, by being connected to a pressure arm connecting assembly installed on the tooling bracket 11. In an embodiment not shown, the base end of the pressure arm 13 can also be directly pivotally connected to the tooling bracket 11. In addition, in an embodiment not shown, the position of the pressure arm connecting assembly 12 relative to the tooling bracket 11 can also be adjusted, for example, in the horizontal direction along the pressure arm pivot axis or in the horizontal direction perpendicular to the pressure arm pivot axis. In this way, the pressure arm 13 and the brake pressure plate 15 can be aligned relative to the rotor core C for better braking.

[0065] In this embodiment, the brake pressure plate 15 can be installed under the pressure arm 13 in an adjustable position through the pressure plate connecting assembly 14. For example, the pressure plate connecting assembly 14 is adjustably arranged along the extension direction of the pressure arm 13. In this way, by setting the adjustable pressure plate connecting assembly 14, the distance between the brake pressure plate 15 and the rotor core can be adjusted, so that during the braking operation, the brake pressure plate 15 can be better aligned with the rotor cores C of different specifications, thereby ensuring the braking effect and improving the adaptability of the tooling.

[0066] Specifically, see Figures 1 to 4 It can be seen that the pressing arm 13 is provided with an elongated hole 131 extending along the extending direction of the pressing arm 13. Figure 7 It can be seen that the pressure plate connecting assembly 14 includes a connecting column 141, a pressure plate spring 142 sleeved on the connecting column 141, a lower stopper 143 arranged at the lower end of the connecting column, and an upper stopper 144 arranged at the upper end of the connecting column 141.

[0067] The connecting column 141 includes a pressure arm connecting section connected to the elongated hole 131 of the pressure arm 13 and a pressure plate connecting section connected to the brake pressure plate 15. The connecting column 141 can move along the extending direction of the elongated hole 131 through the cooperation between the pressure arm connecting section and the elongated hole 131 of the pressure arm 13. In this way, through the cooperation between the connecting column 141 and the elongated hole 131 of the pressure arm 13, the position of the brake pressure plate 15 can be adjusted with a simple structure.

[0068] Continue to see Figures 1 to 3 It can be seen that the connecting column 141 is along its longitudinal direction ( Figures 1 to 3 The pressure plate spring 142 is mounted on the connecting column 141 and is located between the pressure arm 13 and the brake pressure plate 15. Due to the provision of the pressure plate spring 142, when the brake pressure plate 15 contacts the rotor core C, the brake pressure from the pressure arm 13 is buffered by the pressure plate spring 142, making the braking process smoother.

[0069] In an embodiment not shown, the brake pressure plate 15 may also be fixedly installed below the pressure arm 13 via a pressure plate connecting assembly 14 .

[0070] Continue to see Figures 1 to 4 It can be seen that the brake pressure plate 15 includes a first pressure plate portion 151 and a second pressure plate portion 152 arranged at an angle, so that during the braking process, the rotor core C is located within the wrap angle range defined by the first pressure plate portion 151 and the second pressure plate portion 152, and contacts the first pressure plate portion 151 and the second pressure plate portion 152 respectively. In this way, through the first pressure plate portion 151 and the second pressure plate portion 152, the rotor core can be contacted and pressed from both sides to brake, which can make the braking process smoother and better adapt to rotor cores of different specifications, thereby improving adaptability.

[0071] See also Figures 1 to 5 The brake pressure plate 15 is an eight-shaped pressure plate, including a first pressure plate portion 151 and a second pressure plate portion 152 and an intermediate connecting plate 153 integrally connected to the first pressure plate portion 151 and the second pressure plate portion 152. The brake pressure plate 15 is connected to the pressure plate connecting section of the connecting column 141 through the intermediate connecting plate 153, and preferably, the brake pressure plate 15 is symmetrically and rotatably arranged relative to the central axis of the connecting column 141.

[0072] In this embodiment of the present disclosure, due to the symmetrical and rotatable setting of the brake pressure plate 15, during the process of applying brake pressure through the pressure arm 13, the first pressure plate portion 151 and the second pressure plate portion 152 of the brake pressure plate 15 can adaptively contact and cooperate with the rotor core C installed on the dynamic balancing device 200, thereby obtaining a better braking effect.

[0073] See also Figure 5 The dynamic balancing device 200 includes a dynamic balancing bracket 21, a dynamic balancing drive motor 22 installed on the dynamic balancing bracket 21, a dynamic balancing drive belt 23 connected between the dynamic balancing drive motor 22 and the rotor core C, and a dynamic balancing support roller 24 installed on the top of the dynamic balancing bracket 21. The rotor core C is supported on the freely rotating dynamic balancing support roller 24 through the rotor shaft C1 thereon, and the rotor core C rotates at a high speed driven by the dynamic balancing drive belt 23. At this time, the high-speed rotating rotor core C is subjected to a dynamic balancing test by the detection device of the dynamic balancing device, and, as required, the rotor core C is stopped from rotating, and the rotor core C is subjected to a dynamic balancing adjustment operation by adjusting the counterweight on the rotor core C, and then the rotor core C is rotated at a high speed again to continue the dynamic balancing test until the dynamic balancing test passes.

[0074] See also Figure 6a and Figure 6b The operator can reach the braking position by pivoting the pressing arm 13 downward (see Figure 5and Figure 6a ), the brake is achieved by the contact and friction between the brake pressure plate 15 and the rotor core C. After the brake is completed, the operator can pivot the pressure arm 13 upward to the fully open position (see Figure 6b ) to facilitate dynamic balancing of the rotor core C or replacement of the next workpiece to be dynamically balanced.

[0075] Continue to see Figure 6a and Figure 6b It can be seen that the rotor dynamic balancing brake tooling 100 disclosed in the present invention also includes a pressure arm spring 16, a first end of the pressure arm spring 16 is connected to the tooling bracket 11 through the first pivot point A of the pressure arm spring, and a second end is connected to the middle of the pressure arm 13 through the second pivot point B of the pressure arm spring; the pressure arm 13 is able to pivot between a braking position and a fully open position away from the braking position through a pressure arm pivot point O between the pressure arm 13 and the tooling bracket 11, and the pressure arm pivot point O is located between the braking position and the fully open position.

[0076] In this embodiment of the present disclosure, by providing a pressure arm spring 16, the pressure arm can, on the one hand, quickly reach the braking position when performing a braking operation, and on the other hand, can be maintained in a fully open position when replacing a workpiece (a rotor core for a dynamic balancing operation), thereby facilitating operation.

[0077] from Figure 6a and Figure 6b It can also be seen that the free end of the pressure arm 13 can be provided with a brake handle 132, which is convenient for the operator to grasp and makes the braking operation more convenient.

[0078] See also Figure 7 The lower stopper 143 at the lower end of the connecting column 141 prevents the brake pressure plate 15 from being separated from the connecting column 141, and the upper stopper 144 at the upper end prevents the pressure arm 13 from being separated from the connecting column 140. In this embodiment, the connecting column 141 is preferably a screw, and the screw head at the lower end of the screw serves as the lower stopper 143, and a nut is provided at the upper end of the screw, serving as the upper stopper 144. The brake pressure plate 15 and the pressure arm 13 can be conveniently installed together through the connecting column and the two stoppers. Of course, the connecting column 141 can also be any other suitable connecting member, such as a stud, in which case the upper and lower ends of the connecting column can be used as upper and lower stoppers through nuts.

[0079] Continue to see Figure 7 It can be seen that the first pressing plate portion 151 and the second pressing plate portion 152 of the brake pressure plate 15 are each provided with a brake pad 154. The brake pad has good wear resistance and a high friction coefficient. By providing the brake pad, the braking resistance and wear resistance of the brake pressure plate 15 can be improved.

[0080] See also Figure 3 and Figure 7 It can be seen that at least the middle portion of the pressure arm 3 along the extension direction is configured to have a cross-section in a rectangular shape formed by four side walls in order to support the middle portion of the brake pressure plate 15, thereby providing better strength and rigidity.

[0081] The present disclosure has the following advantages:

[0082] 1. The rotor dynamic balancing brake tool disclosed in the present invention brakes the rotor core through a pressure arm and a brake pressure plate, which is safe to operate and easy to use;

[0083] 2. The first and second pressure plates are arranged at an angle, which can be compatible with the largest and smallest rotors of different models. The rotor can be stopped suddenly when running at high speed by simply pressing the brake handle on the pressure arm. It has strong applicability and high production efficiency.

[0084] 3. Use brake pads on the brake pressure plate to contact the surface of the workpiece, and press at high speed to stop the workpiece. This will not cause wear or damage to the workpiece surface, and at the same time, the workpiece can be stopped quickly, improving production efficiency.

[0085] The above are only preferred embodiments of the present disclosure. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present disclosure. These improvements and modifications should also be regarded as the protection scope of the present disclosure.
