Description

Technical Field

[0001] The invention belongs to the technical field of motor production, and in particular relates to a stator paint dripping device with uniform distribution. Background Art

[0002] With the rapid development of China's science and technology economy, the motor is widely used in modern industry and daily life. It is roughly composed of a stator, a rotor and a housing. The stator is the stationary part of the motor, usually composed of a stator core and a stator coil. After power is applied, it generates a magnetic field, causing the rotor to rotate in the housing to drive the output shaft to rotate to provide power. Since the stator needs to be powered during operation, the stator coil needs to be insulated with paint to prevent the coil from short-circuiting or breaking down the insulation to the ground during operation, causing damage to the motor. At the same time, a short circuit may cause the coil temperature to rise, which may cause a fire.

[0003] When dripping paint on the stator coil, the existing stator paint dripping device first puts the stator on the clamp, then controls the clamp to open so that the clamp clamps the stator from the inside, then installs the clamp in the three-jaw chuck, and finally places the paint dripping tube near the coil for dripping paint. When dripping paint on the stator, in order to prevent the insulating paint from being unevenly distributed in the coil, it is necessary to drip paint on the inner and outer rings of the stator at the same time. In the above steps, when clamping the stator, the paint dripping tube needs to be removed, which requires the paint dripping tube to be placed back on the coil before dripping paint, which reduces the work efficiency.

DETAILED DESCRIPTION

[0030] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0031] like Figures 1 to 8 As shown, an embodiment of the present invention provides a uniformly distributed stator paint dripping device, comprising a frame 1 and a three-jaw chuck 2, wherein the three-jaw chuck 2 is rotatably mounted in the frame 1, and the three-jaw chuck 2 comprises a chuck 21 and a clamping jaw 22, and further comprises:

[0032] The clamping structure 3 includes a clamping shaft 31 rotatably mounted inside the frame 1, one end of the clamping shaft 31 passes through the clamping plate 21, and the other end thereof is fixedly connected to a fixed hinge seat 32, and a sliding hinge seat 33 is also slidably sleeved on the outer surface of the clamping shaft 31, and a plurality of first slid grooves 36 are provided on the outer surface of the clamping shaft 31 close to the sliding hinge seat 33, and an inclined slider 37 is slidably connected in the first slid groove 36, and the inclined surface of the inclined slider 37 faces the clamping claw 22, and a plurality of side connecting rods 34 are hinged on the outer surfaces of the fixed hinge seat 32 and the sliding hinge seat 33, and a corresponding side connecting rod 34 is hinged to a transverse connecting rod 35;

[0033] The paint dripping structure 4 includes a mounting seat 41 symmetrically fixedly connected to the inner top surface of the frame 1, the symmetrical mounting seat 41 is fixedly connected with a fixed shaft 42 coaxial with the clamping shaft 31, the outer surface of the fixed shaft 42 is fixedly connected with a symmetrical liquid box 43, a steering ring 45 is slidably connected between the mounting seat 41 and the liquid box 43, a plurality of first piston rods 44 with extended ends abutting against the side of the steering ring 45 are slidably connected in the liquid box 43, a third spring 46 is elastically connected between the steering ring 45 and the mounting seat 41, a paint passing seat 47 is fixedly connected in the horizontal direction of the steering ring 45, an inner paint dripping tube 48 and an outer paint dripping tube 49 are fixedly connected to the side of the paint passing seat 47, a symmetrical steering slide groove 415 is opened on the outer surface of the fixed shaft 42, a steering column 416 located in the steering slide groove 415 is fixedly connected inside the steering ring 45, and after the steering column 416 slides in the steering slide groove 415, the steering ring 45 rotates 90°.

[0034] The present invention provides a paint dripping structure 4. When the stator is installed on the clamping structure 3, the clamping jaw 22 of the three-jaw chuck 2 is controlled to move upward, so that the clamping jaw 22 drives the sliding block 413 to move upward, thereby causing the second piston rod 412 to push the liquid in the first liquid pipe 410 and the second liquid pipe 411, and drives the first piston rod 44 in the liquid box 43 to extend and push the steering ring 45. When the steering rings 45 are pushed away from each other, the steering slide column 416 will slide in the steering slide groove 415, so that after the steering ring 45 moves toward the mounting seat 41, the paint passing seat 47 connected to the steering ring 45 is switched from a vertical state to a horizontal state. At this time, the paint dripping tube will be away from the clamping position where the stator is located. When the clamping jaw 22 moves downward to clamp the clamping shaft 31, the third spring 46 will push The steering ring 45 is away from the mounting seat 41, so that the steering ring 45 and the paint passing seat 47 are switched from a horizontal state to a vertical state together. At the same time, the two steering rings 45 are close to each other, so that the inner paint dripping tube 48 and the outer paint dripping tube 49 are located on the stator coil, so that there is no need to control the position of the paint dripping tube when loading and unloading the stator. Secondly, through the provided clamping structure 3, after the clamping jaws 22 move downward to clamp the clamping shaft 31, the inclined slider 37 is pushed by the clamping jaws 22, so that the inclined slider 37 pushes the sliding hinge seat 33. At this time, as the sliding hinge seat 33 moves toward the fixed hinge seat 32, the side connecting rods 34 on both sides will drive the horizontal connecting rod 35 to move in the direction away from the clamping shaft 31, and then clamp the stator from the inside of the stator, thereby improving the loading and unloading efficiency of the stator, and thus improving the production efficiency.

[0035] like Figure 3 As shown, it also includes a driving structure 6, which includes a motor 61 fixedly connected to the inside of the frame 1 and a driven gear 63 fixedly sleeved on the chuck 21, the output shaft of the motor 61 is fixedly sleeved with a driving gear 62, the driving gear 62 and the driven gear 63 are meshed with each other, and the motor 61 is located inside the frame 1 away from the clamping structure 3.

[0036] By using the cooperation of the driving gear 62 and the driven gear 63, the motor 61 is started to control the three-jaw chuck 2 to rotate, and then the three-jaw chuck 2 drives the clamping structure 3 to rotate, thereby improving the stability of the stator during paint dripping, thereby ensuring that the insulating paint on the stator is evenly distributed.

[0037] like Figure 1 , Figure 2 and Figure 6 As shown, a symmetrical guide block 414 is fixedly connected to the inner side surface of the frame 1, a sliding block 413 is slidably connected between the two guide blocks 414, a first liquid pipe 410 and a second liquid pipe 411 are fixedly connected to the top surface of the frame 1, one end of the first liquid pipe 410 and the second liquid pipe 411 are both connected to a liquid box 43, and the other ends of the first liquid pipe 410 and the second liquid pipe 411 are slidably connected to the second piston rod 412, and the two second piston rods 412 are fixedly connected to the top surface of the sliding block 413.

[0038] When the stator is finished being paint dripped, as the motor 61 stops, the three-jaw chuck 2 will be affected by gravity to make one jaw 22 vertically upward, and then the three-jaw chuck 2 is operated to loosen its jaw 22, so that the clamping structure 3 releases the stator to take the stator out of the device. At this time, as the upward jaw 22 rises, it pushes the sliding block 413 to rise, and then drives the two second piston rods 412 to rise and squeeze the hydraulic oil in the first liquid pipe 410 and the second liquid pipe 411, and then the first piston rod 44 in the liquid box 43 extends and pushes the steering ring 45 to move toward the mounting seat 41. At this time, the paint dripping tube leaves the area where the stator is located, and then the steering ring 45 is affected by the steering slide column 416 and rotates, so that the vertically downward paint dripping tube turns to a horizontal state, which is convenient for the staff to load and unload the stator.

[0039] like Figure 4 and Figure 5 As shown, a guide slide post 38 is fixedly connected inside the first slide groove 36 , and the guide slide post 38 passes through the inclined slider 37 . A first spring 39 is elastically connected between the inclined slider 37 and the inner surface of the first slide groove 36 , and the first spring 39 is sleeved on the guide slide post 38 .

[0040] After the stator is put on the clamping structure 3, the three-jaw chuck 2 is operated to make the clamping jaw 22 descend and clamp the clamping shaft 31, so that the clamping structure 3 and the three-jaw chuck 2 rotate synchronously. At this time, the front end of the clamping jaw 22 will contact the inclined surface of the inclined slider 37 and push the inclined slider 37 to move away from the three-jaw chuck 2. At this time, the inclined slider 37 will push the sliding hinge seat 33 to move. Through the cooperation of the side connecting rod 34 and the transverse connecting rod 35, the transverse connecting rod 35 moves in the direction away from the clamping shaft 31 and clamps and centers the stator from the inside, thereby realizing rapid clamping of the stator and improving work efficiency.

[0041] like Figure 4 and Figure 5 The outer surface of the clamping shaft 31 is slidably sleeved with a support slide 311, which is located between the fixed hinge seat 32 and the sliding hinge seat 33. The fixed hinge seat 32 is fixedly connected with a plurality of first slide posts 310 that are centrally symmetrical on the side facing the sliding hinge seat 33. The first slide posts 310 penetrate the support slide 311 and the sliding hinge seat 33. The outer surface of the first slide posts 310 is movably sleeved with symmetrical second springs 314, which are located on both sides of the support slide 311. The support slide 311 has a plurality of symmetrical second slide grooves 312 arranged inside, and a vertical slide post 313 is slidably connected inside the second slide groove 312, and one end of the vertical slide post 313 is fixedly connected inside the horizontal connecting rod 35.

[0042] The supporting slide 311 is located between the fixed hinge seat 32 and the sliding hinge seat 33, and is internally slidably connected with a vertical sliding column 313. When the sliding hinge seat 33 moves toward the fixed hinge seat 32, the side links 34 on both sides of the transverse link 35 are prone to rotate at different angles due to the movement of the sliding hinge seat 33, so that the two ends of the transverse link 35 are not at the same height, resulting in the inner wall of the stator being scratched when the stator is clamped, causing processing damage to the stator. By setting up symmetrical vertical sliding columns 313, the two ends of the transverse link 35 are at the same height during the movement, preventing damage to the stator after one end contacts the inner wall of the stator, while also ensuring the clamping effect, preventing the stator from being unevenly distributed in the insulating paint during the subsequent rotating paint dripping process due to poor clamping effect.

[0043] like Figure 1 , Figure 2 and Figure 6 As shown, the symmetrical guide block 414 is located directly above the chuck 21. When the three-jaw chuck 2 is stationary, the sliding block 413 is located directly above one of the jaws 22. The bottom surface of the sliding block 413 is provided with an arc groove, which cooperates with the top of the jaw 22. When the jaw 22 is away from the center of the chuck 21, the chuck 21 does not rotate. The steering ring 45 and the paint passing seat 47 are close to the liquid box 43 in a vertical state, and the inner paint dripping pipe 48 is located above the inner ring of the stator body coil, and the outer paint dripping pipe 49 is located above the outer ring of the stator body coil. The top of the frame 1 is fixedly connected with a paint supply device 5, and the paint passing seat 47 is connected with the paint supply device 5 through a pipeline.

[0044] The setting of the arc groove prevents the clamping jaw 22 from being deflected by external force when operating the three-jaw chuck 2, resulting in the hydraulic oil in the first liquid pipe 410 and the second liquid pipe 411 being unable to provide sufficient force to push the steering ring 45 to move and rotate, ensuring that when the three-jaw chuck 2 is used to allow the clamping structure 3 to loosen the stator, the paint dripping tube of the paint dripping structure 4 leaves the area where the stator is located, facilitating the loading and unloading of the stator and improving work efficiency.

[0045] Working principle:

[0046] When using the present device to drip paint on the stator coils at both ends of the stator, first ensure that the jaws 22 of the three-jaw chuck 2 are in an open state, and the inner paint dripping tube 48 and the outer paint dripping tube 49 are in a horizontal state, then the stator is sleeved on the clamping structure 3, and then the three-jaw chuck 2 is operated to make the jaws 22 retract inward. As the jaws 22 move, the third spring 46 pushes the steering ring 45 away from the mounting seat 41. When the steering ring 45 moves, the steering slide column 416 fixedly connected thereto slides in the steering slide groove 415, thereby driving the steering ring 45 to rotate. As the steering ring 45 rotates and moves, the inner paint dripping tube 48 and the outer paint dripping tube 49 will switch from a horizontal state to a vertical state, and the inner paint dripping tube 48 and the outer paint dripping tube 49 will be located on the inner ring and the outer ring of the stator clamped by the clamping structure 3 for subsequent paint dripping process.

[0047] During the process of closing the clamp 22, the clamp 22 will push the inclined slider 37 to move, and then push the sliding hinge seat 33 to move. At this time, through the cooperation of the side connecting rod 34 and the transverse connecting rod 35, the transverse connecting rod 35 contacts the inner wall of the stator and clamps it to the stator, while making the axis of the stator colinear with the axis of the clamping shaft 31 to ensure concentricity during rotation.

[0048] As the paint dripping is completed, the three-jaw chuck 2 is operated to open the jaws 22. As the upward jaws 22 move upward, the sliding hinge seat 33 is pushed by the second spring 314 to move in the direction close to the three-jaw chuck 2, thereby releasing the stator. At the same time, as the jaws 22 move upward, the sliding block 413 is pushed upward, so that the hydraulic oil in the first liquid pipe 410 and the second liquid pipe 411 pushes the first piston rod 44 in the two liquid boxes 43 to extend and push the steering ring 45. As the steering ring 45 is limited by the steering slot 415 and moves and rotates, it will eventually compress the third spring 46. At the same time, the inner paint dripping tube 48 and the outer paint dripping tube 49 are in a horizontal state, close to the inner top surface of the frame 1. At this time, the paint dripping tube is not in the stator area, and the stator can be easily loaded and unloaded.

[0049] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
