Abstract
Description
Technical Field
[0001] This utility model relates to the field of stator cooling technology, specifically a stator air-cooled cooling device. Background Technology
[0002] The stator core is an important component of the motor's magnetic circuit. It consists of parts such as sector plates, ventilation slots, and positioning ribs. It is responsible for good magnetic conductivity and low loss. It is made by stamping silicon steel sheets into sector plates and stacking them on positioning ribs. The core is pressed into a whole by upper and lower toothed pressure plates and tension bolts. The part where the windings are placed is subjected to the combined effects of mechanical force, thermal stress, and electromagnetic force.
[0003] Patent CN219839748U discloses an air-cooling device for processing generator stator cores, including a base. A slide is mounted on one side of the top surface of the base, and a bracket is fixedly connected to the other side of the top surface of the base. First motors are fixedly connected to both sides of the top surface of the bracket, and first threaded rods are fixedly connected to the output ends of the first motors on both sides. A mounting frame is slidably connected to the middle of the bracket. First fans are fixedly connected to the middle of the outer sides of the mounting frame, and a second fan is fixedly connected to the middle of the outer side of the mounting frame. In this invention, driving the first motor can move the mounting frame, which in turn can simultaneously move the exhaust pipe and the horizontal pipe to adjust their positions. This allows the device to cool stators of different models, improving its adaptability.
[0004] The above-mentioned device has certain shortcomings in its use: The device directly places the stator on the inner and outer rotating rollers on the top of the slide block. When cooling it, the inner rotating roller can be rotated by driving the third motor. The inner rotating roller can drive the generator stator to rotate and cool the inside and outside of the stator. Initially, the mounting block and inner rotating roller are moved down by the weight of the stator itself. The spring is compressed and its elastic force can be used to press the inner rotating roller against the bottom surface of the generator stator. However, it is not fixed. There is a certain safety hazard when rotating, as it may lose contact with the inner and outer rotating rollers. Since the spacing of the outer rotating rollers is fixed, the above-mentioned device is not suitable when the diameter is larger than the spacing of the outer rotating rollers.
[0005] Therefore, this utility model provides a stator air-cooled cooling device to solve the above problems. Utility Model Content
[0006] To address the shortcomings of existing technologies, this invention provides a stator air-cooled cooling device, which solves the aforementioned problems.
[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a stator air-cooled cooling device, including a workbench, a placement component installed in the middle of the top wall of the workbench, and a cooling component installed on the left side of the top wall of the workbench;
[0008] The placement assembly includes a mounting base. The mounting base is bolted to the center of the workbench top wall on both sides via fastening bolts. An electric slide rail is mounted on the top wall of the mounting base. An electric slider is slidably mounted on the outer wall of the electric slide rail. A U-shaped frame is fixedly mounted on the top wall of the electric slider. A bidirectional lead screw is rotatably mounted on the bottom of the inner wall of the U-shaped frame. A drive motor is fixedly mounted on the right side wall of the U-shaped frame. Sliding blocks are bolted to both sides of the outer wall of the bidirectional lead screw. Clamping seats are fixedly mounted on the top walls of the sliding blocks. Limiting rods are fixedly mounted on the front and rear parts of the inner wall of the U-shaped frame. Each clamping seat has an opening on its side wall. A circular frame is fixedly mounted on the side adjacent to the clamping seat and corresponding to the opening. An opening is provided on the left side wall of the U-shaped frame. Inclined plates are fixedly mounted on the front and rear parts of the inner wall of the U-shaped frame.
[0009] The above technical solution, through the arrangement of the placement components, can clamp and fix stators of different diameters, preventing shaking during cooling and providing good safety.
[0010] Furthermore, the power shaft of the drive motor is fixedly connected to the bidirectional lead screw through the U-shaped frame via a bearing, the bottom wall of the sliding block is slidably connected to the inner bottom wall of the U-shaped frame, and the outer wall of the limiting rod is slidably connected to the clamping seat.
[0011] Through the above technical solution, the drive motor's power shaft drives the bidirectional lead screw to rotate, thereby causing the sliding blocks to move away from or closer to each other along the outer wall of the bidirectional lead screw.
[0012] Furthermore, the cooling assembly includes a U-shaped base, the front and rear parts of the bottom wall of the U-shaped base are screwed to the left side of the top wall of the workbench by fastening bolts, and a fan is screwed to the top wall of the U-shaped base by fastening bolts, and the air inlet of the fan is connected to the outside.
[0013] Through the above technical solution, the fan provides a cooling environment for the stator.
[0014] Furthermore, the air outlet of the fan is connected to a flexible hose, and the front and rear walls of the U-shaped seat are provided with limit grooves, and limit sliders are slidably installed on the inner walls of the limit grooves.
[0015] Through the above technical solution, the fan delivers cool air into the C-shaped tube through a flexible hose and cools the external part of the stator through the exhaust hood.
[0016] Furthermore, the same movable frame is fixedly installed on each side of the limiting slider. The movable frame is "C" shaped. A C-shaped tube is fixedly installed on the inner wall of the movable frame through a fixed seat. A connecting pipe is connected to the middle of the outer wall of the C-shaped tube. The outer wall of the C-shaped tube is connected to the bottom end of the movable hose. Several exhaust hoods are connected to the outer walls of the C-shaped tube and the connecting pipe.
[0017] With the above technical solution, when the mobile frame moves up and down, it drives the limiting slider to slide up and down along the inner wall of the limiting groove.
[0018] Furthermore, electric push rods are fixedly installed on both the front and rear parts of the top wall of the U-shaped seat, and the movable ends of the electric push rods slide through the U-shaped seat and are fixedly connected to the top wall of the corresponding limiting slider.
[0019] Through the above technical solution, the electric actuator pushes the limiting slider to slide within the inner wall of the limiting groove.
[0020] Furthermore, support legs are fixedly installed at the four corners of the bottom wall of the workbench.
[0021] Through the above technical solution, the support leg plays a supporting and fixing role for the entire device.
[0022] Beneficial effects
[0023] This utility model provides a stator air-cooled cooling device. Compared with the prior art, it has the following advantages:
[0024] Beneficial effects:
[0025] (1) The stator air-cooled cooling device is used to place the stator between the clamping seats in the U-shaped frame. The drive motor drives the bidirectional lead screw to rotate. The sliding block slides along the outer wall of the bidirectional lead screw on the inner wall of the U-shaped frame. When the sliding block moves on the outer wall of the limit rod, it drives the clamping seat and the circular frame to clamp and fix the stator. The circular frame enters the inner wall of the stator and is limited. The electric slider starts to slide to the left on the inner wall of the electric slide rail, which drives the U-shaped frame, the clamping seat and the clamped stator to approach the U-shaped seat. The connecting pipe drives the exhaust hood through the through-hole and the circular frame into the stator, so that the cold air blown out by the exhaust hood can fully cool the inside and outside of the stator. When cooling the stator, stators of different diameters can be clamped and fixed to prevent them from falling off. It can also perform all-round cooling treatment on the inside and outside of the stator.
[0026] (2) The stator air-cooled cooling device pushes the limiting slider to slide in the inner wall of the limiting groove through the electric push rod. The limiting slider drives the moving frame in the U-shaped seat. The moving frame drives the C-shaped tube, connecting tube and exhaust hood to move downward. The position of the connecting tube corresponds to the position of the inlet and the outlet. The fan blows cold air through the movable hose and blows it out from the exhaust hood through the C-shaped tube and connecting tube. This allows the position of the C-shaped tube and connecting tube from the exhaust hood to be adjusted up and down and matched to the position of the stator, which is convenient for cooling the stator.

[0034] 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.
[0035] Example 1:
[0036] Please see Figure 1-6A stator air-cooled cooling device includes a workbench 1, a placement component 4 installed in the middle of the top wall of the workbench 1, and a cooling component 3 installed on the left side of the top wall of the workbench 1.
[0037] The placement component 4 includes a mounting base 41. The mounting base 41 is bolted to the center of the top wall of the workbench 1 on both the left and right sides. An electric slide rail 42 is mounted on the top wall of the mounting base 41. An electric slider 43 is slidably mounted on the outer wall of the electric slide rail 42. A U-shaped frame 44 is fixedly mounted on the top wall of the electric slider 43. A double-acting lead screw 46 is rotatably mounted on the bottom of the inner wall of the U-shaped frame 44. A drive motor 410 is fixedly mounted on the right side wall of the U-shaped frame 44. Sliding blocks 47 are bolted to the left and right sides of the outer wall of the double-acting lead screw 46. Clamping seats 48 are fixedly mounted on the top wall of each sliding block 47. Limiting rods 49 are fixedly installed on the front and rear sides of the inner wall of the U-shaped frame 44. Passage openings 411 are opened on the side walls of the clamping seat 48. A circular frame 412 is fixedly installed on the side of the clamping seat 48 adjacent to the position of the passage opening 411. A through opening 45 is opened on the left side wall of the U-shaped frame 44. Inclined plates 413 are fixedly installed on the front and rear sides of the inner wall of the U-shaped frame 44. The power shaft of the drive motor 410 passes through the U-shaped frame 44 through the bearing and is fixedly connected to the bidirectional lead screw 46. The bottom wall of the sliding block 47 is slidably connected to the inner bottom wall of the U-shaped frame 44. The outer wall of the limiting rod 49 slides through the clamping seat 48.
[0038] In this embodiment of the utility model, the purpose of this arrangement is that the placement component 4 can clamp and fix stators of different diameters to prevent them from sliding and falling off during cooling. When the sliding block 47 moves, it drives the clamping seat 48 to fix the stator. At the same time, the circular frame 412 enters a certain distance into the inner wall of the stator, and impurities that may exist on the surface of the stator during cooling are blown off and fall onto the worktable 1 through the inclined plate 413. The clamping seat 48 slides along the outer wall of the limiting rod 49 to prevent displacement.
[0039] Example 2:
[0040] Please see Figure 1-6This embodiment provides a technical solution based on Embodiment 1: The cooling assembly 3 includes a U-shaped seat 31. The front and rear parts of the bottom wall of the U-shaped seat 31 are screwed to the left side of the top wall of the workbench 1 by fastening bolts. A fan 34 is screwed to the top wall of the U-shaped seat 31 by fastening bolts. The air inlet of the fan 34 is connected to the outside, and the air outlet of the fan 34 is connected to a flexible hose 35. Limiting grooves 32 are provided on the front and rear inner walls of the U-shaped seat 31. Limiting sliders 310 are slidably installed on the inner walls of the limiting grooves 32. The adjacent side of the limiting sliders 310 is fixedly installed. There is a single movable frame 36, which is C-shaped. A C-shaped tube 37 is fixedly installed on the inner wall of the movable frame 36 through a fixed seat. A connecting tube 38 is connected to the middle of the outer wall of the C-shaped tube 37. The outer wall of the C-shaped tube 37 is connected to the bottom end of the movable hose 35. Several exhaust hoods 39 are connected to the outer walls of the C-shaped tube 37 and the connecting tube 38. Electric push rods 33 are fixedly installed on the front and rear of the top wall of the U-shaped seat 31. The movable ends of the electric push rods 33 slide through the U-shaped seat 31 and are fixedly connected to the top wall of the corresponding limit slider 310. Support legs 2 are fixedly installed at the four corners of the bottom wall of the workbench 1.
[0041] In this embodiment of the utility model, the purpose of this arrangement is that the cooling component 3 is used to clamp and fix the stator before cooling it, and to deliver cold air into the flexible hose 35 through the fan 34. The air is then discharged through the C-shaped pipe 37, the connecting pipe 38 and the exhaust hood 39, thereby enabling air cooling of the stator's interior and exterior. The connecting pipe 38 enters the stator through the port 411 and the through port 45, and the cold air output from the exhaust hood 39 on the connecting pipe 38 cools the stator's interior.
[0042] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0043] During operation, the stator to be cooled is first placed between the clamping seats 48 inside the U-shaped frame 44 using an external power supply and controller, electric push rod 33, fan 34, electric slide rail 42, electric slider 43, and drive motor 410. The drive motor 410 drives the bidirectional lead screw 46 to rotate. When the bidirectional lead screw 46 rotates, it drives the sliding block 47 to slide along the outer wall of the bidirectional lead screw 46 on the inner wall of the U-shaped frame 44. When the sliding block 47 moves on the outer wall of the limiting rod 49, it drives the clamping seats 48 and the circular frame 412 to clamp and fix the stator, and the circular frame 412 enters the inner wall of the stator for limitation. At the same time, the electric push rod 33 pushes the limiting slider 310 to slide in the inner wall of the limiting groove 32. The limiting slider 310 drives the movement of the stator... The moving frame 36 is in the U-shaped seat 31. At the same time, the moving frame 36 drives the C-shaped tube 37, the connecting tube 38, and the exhaust hood 39 to move downward, so that the connecting tube 38 corresponds to the position of the through port 45 and the through port 411. The fan 34 is started and blows cold air through the movable hose 35 and through the C-shaped tube 37 and the connecting tube 38 to blow out from the exhaust hood 39. The electric slider 43 starts to slide to the left on the inner wall of the electric slide rail 42, thereby driving the U-shaped frame 44, the clamping seat 48, and the clamped and fixed stator to move closer to the U-shaped seat 31. Then, the connecting tube 38 drives the exhaust hood 39 through the through port 45, the through port 411, and the circular frame 412 to enter the interior of the stator, so that the cold air blown out by the exhaust hood 39 can fully cool the interior and exterior of the stator.
