Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal stator support technology, specifically to an easily adjustable metal stator support. Background Technology
[0002] The stator is the stationary part of an electric motor or generator. It consists of three parts: the stator core, the stator windings, and the frame. The stator is used to generate a rotating magnetic field.
[0003] However, existing metal stator supports mostly use clamps with the same arc shape as the stator surface to hold and fix the stator from the outside when supporting the processing. This fixing method requires adjusting the clamps on both sides to move the stator, which is repetitive and increases the complexity. In addition, fixing the stator from the outside, regardless of the size of the clamps, will always occupy a certain space on the stator surface, making it difficult to fully process the stator surface. It requires manual adjustment of the stator's position, which is not conducive to fixing and processing.
[0004] Therefore, in view of this, we studied and improved the existing structure to address its shortcomings, and proposed a metal stator support that is easy to adjust. Utility Model Content
[0005] The purpose of this invention is to provide an easily adjustable metal stator support to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an easily adjustable metal stator support, comprising a support body, two synchronous cylinders fixedly installed on the left inner wall of the support body, the upper end of the synchronous cylinders passing through the support body and fixedly installed on the same movable plate, a fixing mechanism installed on the right side of the surface of the movable plate, and a locking mechanism provided on the right side of the fixing mechanism.
[0007] Preferably, the fixing mechanism includes a sleeve fixedly installed on the right side of the movable plate surface, the outer surface of the sleeve having four through cavities evenly distributed thereon, and the inner surface of the sleeve having a bidirectional lead screw rotatably mounted on the middle via a bearing.
[0008] Preferably, the fixing mechanism further includes a bidirectional lead screw with an internal threaded ring on both sides, and four movable rods are rotatably arranged around the surface of the internal threaded ring. The ends of two corresponding movable rods on the same horizontal line away from the internal threaded ring are rotatably mounted on the same support plate through the same bearing.
[0009] Preferably, the locking mechanism includes a handwheel that is fixedly installed through the sleeve at the right end of the bidirectional lead screw, and positioning holes are circumferentially distributed at the right end of the outer surface of the sleeve at the bidirectional lead screw penetration part.
[0010] Preferably, the locking mechanism further includes a pin that is slidably inserted into the positioning hole, a connecting ring that is fixedly installed on the left side of the pin, and a spring that is sleeved on the right side of the connecting ring and fixedly installed on the outer side of the pin.
[0011] Preferably, the right end of the pin slides through the handwheel, and the right end of the spring is fixedly connected to the handwheel.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This utility model, through the arrangement of a fixing mechanism, sleeve, through cavity, bidirectional screw, internal threaded ring, movable rod, and supporting rubber plates, allows the stator to be fitted onto the outer surface of the sleeve. Then, by rotating the bidirectional screw, the internal threaded ring is limited by the movable rod within the through cavity. Driven by the thread pattern, the internal threaded ring moves in opposite directions according to the rotation direction of the bidirectional screw. When the internal threaded ring moves in opposite directions, the four supporting rubber plates are simultaneously pushed out through the movable rod by the squeezing force, causing the supporting rubber plates to expand and increase the diameter of the sleeve. This internal squeezing and supporting of the entire stator fixes it. This method allows for flexible adjustment and fixation according to stators of different inner diameters. Furthermore, this fixing method does not occupy space on the outer surface of the stator, facilitating thorough processing of the stator's outer surface. When the internal threaded ring moves in the opposite direction, it pulls the movable rod, causing the supporting rubber plates to contract. The stator then loses the pushing tension of the supporting rubber plates and can be disassembled.
[0014] 2. This utility model, through the setting of a locking mechanism, positioning hole, handwheel, pin, connecting ring, and spring, requires that when fixing the stator, the pin must first be pulled to move it out of the positioning hole. At this time, the handwheel can be used to conveniently and quickly drive the bidirectional lead screw for fixing. After the stator is fixed, the pin is released, and under the pushing force of the spring, the connecting ring pushes the pin into the positioning hole at the corresponding point, thereby fixing the handwheel and thus fixing the bidirectional lead screw. This prevents the bidirectional lead screw from rotating secondaryly, which could lead to loosening of the fixation, and improves the fixation firmness. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] like Figures 1-3 As shown, an easily adjustable metal stator support includes a support body 1. Two synchronous cylinders 2 are fixedly installed on the inner left side of the support body 1. The upper end of the synchronous cylinders 2 passes through the support body 1 and is fixedly installed on the same movable plate 3. A fixing mechanism 4 is installed on the right side of the surface of the movable plate 3, and a locking mechanism 5 is provided on the right side of the fixing mechanism 4.
[0021] By adopting the above technical solution, the height of the movable plate 3 can be adjusted by the synchronous cylinder 2, thereby changing the position of the fixed mechanism 4 where the stator is installed.
[0022] Furthermore, the fixing mechanism 4 includes a sleeve 401 fixedly installed on the right side of the surface of the movable plate 3. The outer surface of the sleeve 401 has four through cavities 402 evenly distributed. The inner surface of the sleeve 401 is rotatably provided with a bidirectional lead screw 403 through a bearing. The fixing mechanism 4 also includes an internal threaded ring 404 with threaded connections on both sides on the surface of the bidirectional lead screw 403. Four movable rods 405 are evenly distributed and rotatably provided around the surface of the internal threaded ring 404. The ends of two corresponding movable rods 405 on the same horizontal line away from the internal threaded ring 404 are rotatably installed with the same support plate 406 through the same bearing.
[0023] By adopting the above technical solution, the bidirectional lead screw 403 is rotated and the internal threaded ring 404 is limited by the through cavity 402 through the movable rod 405. Driven by the thread pattern, the internal threaded ring 404 moves in opposite or opposite directions according to the rotation direction of the bidirectional lead screw 403.
[0024] The internal threaded ring 404 moves in opposite directions, and the four support rubber plates 406 are pushed out simultaneously through the movable rod 405 by the squeezing force, so that the support rubber plates 406 expand and increase the diameter of the sleeve 401, squeezing and supporting the entire stator from the inside, and fixing the stator.
[0025] When the internal threaded ring 404 moves in the opposite direction, it can pull the movable rod 405, causing the support plate 406 to contract. The stator loses the pushing tension of the support plate 406, and can then be disassembled.
[0026] Furthermore, the locking mechanism 5 includes a handwheel 502 fixedly installed through the sleeve 401 at the right end of the bidirectional lead screw 403, and positioning holes 501 are circumferentially distributed at the right end of the outer surface of the sleeve 401 at the through part of the bidirectional lead screw 403.
[0027] By adopting the above technical solution, the bidirectional lead screw 403 can be rotated conveniently and quickly using the handwheel 502.
[0028] Furthermore, the locking mechanism 5 also includes a pin 503 that is slidably inserted into the positioning hole 501. A connecting ring 504 is fixedly installed on the left side of the pin 503. A spring 505 is sleeved on the right side of the connecting ring 504 and fixedly installed on the outer side of the pin 503. The right end of the pin 503 slides through the handwheel 502, and the right end of the spring 505 is fixedly connected to the handwheel 502.
[0029] By adopting the above technical solution, when the pin 503 is inserted into the positioning hole 501, the positioning hole 501 limits the pin 503, and the pin 503 passes through the handwheel 502, which can limit the handwheel 502 and prevent the handwheel 502 from driving the double-acting screw 403 to rotate twice.
[0030] Spring 505 applies a leftward thrust to pin 503 through connecting ring 504, ensuring that pin 503 can be stably inserted into positioning hole 501.
[0031] Working Principle: When using this easily adjustable metal stator support, firstly, the stator is fitted onto the outer surface of the sleeve 401. To fix the stator, the pin 503 needs to be pulled to move it out of the positioning hole 501. At this time, the double-acting screw 403 can be easily and quickly driven by the handwheel 502. Rotating the double-acting screw 403 causes the internal threaded ring 404 to be limited by the through cavity 402 via the movable rod 405. Driven by the thread pattern, the internal threaded ring 404 moves in opposite directions. Using the squeezing force, the four support plates 406 are pushed out simultaneously through the movable rod 405, causing the support plates 406 to expand and increase the diameter of the sleeve 401, thus squeezing and supporting the entire stator from the inside, and thus fixing the stator. After the stator is fixed, the pin 503 is released. Under the pushing force of the spring 505, the pin 503 is pushed into the positioning hole 501 at the corresponding position by the connecting ring 504, thereby fixing the handwheel 502. This fixes the bidirectional lead screw 403, preventing it from rotating twice. When disassembly is required, the pin 503 is pulled out again, and the handwheel 502 is rotated in the opposite direction. The bidirectional lead screw 403 rotates in the opposite direction synchronously, and the internal thread ring 404 moves in the opposite direction, which can pull the movable rod 405, causing the support plate 406 to contract. The stator loses the pushing tension of the support plate 406, and can then be disassembled. This is the working principle of the easily adjustable metal stator bracket.
