Description

Technical Field

[0002] A linear motor is a structural deformation of a rotating motor. It can be seen as a rotating motor cut in the radial direction. The working principle of a linear motor is to input a large current and move at high speed with a large acceleration. The fixation of the motor winding and the cooling of the motor are relatively important influencing factors. The offset or protrusion of the winding may cause the temperature of some parts of the motor to rise sharply. When the temperature of the motor exceeds the temperature resistance limit of the motor material, it will cause damage to the surface of the winding, which may easily cause the insulation strength between turns to decrease. When the voltage is too high, the insulating paint will be broken down, causing a short circuit between turns, and in severe cases, the motor will fail.

[0031] 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.

[0032] like Figures 1 to 8 As shown, the present invention provides a linear motor with a rotor cooling structure, including a linear motor stator 1, a linear motor rotor 2 slidably mounted on the top of the linear motor stator 1, a circulating water tank 3 fixedly mounted on one side of the top of the linear motor rotor 2, a cooling block 4 fixedly mounted inside the linear motor rotor 2, a plurality of groups of linear motor cores 45 fixedly mounted on the top of the inner wall of the cooling block 4 and laterally distributed at equal distances, and a copper coil 46 wound on the surface of the linear motor core 45, and also includes a dual-zone water circulation mechanism, which is arranged inside the circulating water tank 3 and is used for circulating cooling.

[0033] refer to Figure 6The dual-zone water circulation mechanism includes a piston block 31, a first water inlet 32, a second water inlet 33 and a tension spring 34. The piston block 31 is slidably installed at the center of the circulating water tank 3. The inner center of the circulating water tank 3 laterally forms a pumping chamber. The first water inlet 32 ​​is opened on both sides of the front of the pumping chamber, and the second water inlet 33 is opened on both sides of the back of the pumping chamber. The inner walls of the first water inlet 32 ​​and the second water inlet 33 are fixedly installed with tension springs 34. The side of the first water inlet 32 ​​close to the pumping chamber and the side of the second water inlet 33 away from the pumping chamber are both plugged with a sealing block 35, and the other end of the tension spring 34 is fixedly installed with the sealing block 35.

[0034] As a technical optimization scheme of the present invention, the piston block 31 can perform negative pressure pumping by sliding left and right. Before pumping, the interior of the circulating water tank 3 needs to be filled with liquid. When the piston block 31 moves to the right, the sealing block 35 at the second water inlet 33 on the right is squeezed out of the liquid on the right wall by the liquid negative pressure. At the same time, the sealing block 35 at the first water inlet 32 ​​on the left is retracted into the pumping chamber. Under negative pressure, the liquid enters the left side of the pumping chamber. Subsequently, when the piston block 31 moves to the left, the liquid that has just been filled with the left side of the pumping chamber is discharged from the second water inlet 33 on the left under negative pressure. At the same time, negative pressure pumping is performed at the first water inlet 32 ​​on the right. The liquid pushes the sealing block 35 at the first water inlet 32 ​​on the right to enter the right side of the pumping chamber for a new round of pumping. Multiple cycles are performed in sequence to achieve repeated pumping, and each time the sealing block 35 is pushed open, it can be reset by the tension of the tension spring 34 and sealed again.

[0035] The driving speed synchronization driving mechanism is used to synchronize the driving speed of the linear motor mover 2 to drive the water circulation; Figure 2 The driving speed synchronous driving mechanism includes a protective side cover 21, a gear frame 211, a limit shaft 212, a driving shaft 213, a first bevel tooth 2131, a second bevel tooth 2132, a driven component and a speed change component. The protective side cover 21 is fixedly mounted on the front side of the linear motor mover 2, the gear frame 211 is fixedly mounted on the inner wall of the protective side cover 21, the limit shaft 212 is fixedly mounted at the inner center of the protective side cover 21, the driving shaft 213 is rotatably mounted inside the gear frame 211, the first bevel tooth 2131 is fixedly mounted on the top of the driving shaft 213, the second bevel tooth 2132 is meshed on the rear side of the top of the first bevel tooth 2131, and is rotatably matched with the front side of the linear motor mover 2, the speed change component is arranged on the front side of the linear motor mover 2 and is used in conjunction with the first bevel tooth 2131, the driven component is used to convert the moving speed of the linear motor mover 2 into a driving speed, and the speed change component is used to amplify the converted rotation speed.

[0036] As a technical optimization solution of the present invention, the protective side cover 21 can protect the speed change assembly and prevent external debris from affecting the stability of the mechanical drive. The gear rack 211 can stably limit the drive shaft 213 and protect the linkage gear 2133. After the driven assembly drives the drive shaft 213, it drives the second bevel gear 2132 to rotate by being fixedly synchronized with the first bevel gear 2131, thereby driving the speed change assembly to increase the speed and perform a water pumping operation.

[0037] The reciprocating conversion mechanism is arranged on one side of the top of the linear motor mover 2 and is used to convert the driving speed into a reciprocating pumping action to cooperate with the dual-zone water circulation mechanism to pump water; Figure 2 The reciprocating conversion mechanism includes a rotary reciprocating switching assembly, a driving disk 22, a guide frame 221, a driving frame 222, a pushing frame 223, a sliding column 224 and a piston rod 225. The driving disk 22 is arranged on the side of the top of the linear motor mover 2 away from the circulating water tank 3. The sliding column 224 is fixedly installed on the side of the top of the driving disk 22 close to the circulating water tank 3. The sliding column 224 slides with the driving frame 222. The driving frame 222 is slidably installed on the inner side of the guide frame 221. The guide frame 221 is fixedly installed on the top of the linear motor mover 2 and is located on both sides of the driving disk 22. The pushing frame 223 is fixedly installed at the top center of the driving frame 222. The piston rod 225 is fixedly installed on the side of the pushing frame 223 close to the circulating water tank 3. One end of the piston rod 225 close to the circulating water tank 3 passes through the circulating water tank 3 and extends to the inside of the circulating water tank 3 and is fixedly installed with the piston block 31. The rotary reciprocating switching assembly is arranged on the side of the front side of the linear motor mover 2 away from the circulating water tank 3, and is used to convert the horizontal driving axis into the longitudinal driving axis.

[0038] The rotary reciprocating switching assembly can convert the horizontal drive axis into the longitudinal drive axis. At the same time, the drive disk 22 is driven to rotate, which drives the sliding column 224 to rotate. When the sliding column 224 rotates, the drive frame 222 that slides with it moves back and forth left and right under the limit of the guide frame 221, and at the same time drives the pushing frame 223 to push back and forth, and then drives the piston rod 225 to drive back and forth. The piston rod 225 can drive the piston block 31 to move back and forth to realize the operation of circulating water pumping.

[0039] refer to Figure 2 and Figure 4The speed change assembly includes a speed change gear 1 214, a speed change gear 215, a speed change gear 3 216, a speed change gear 4 217 and a third helical tooth 2171. The speed change gear 1 214 is fixedly mounted on the surface of the second helical tooth 2132. The speed change gear 2 215 is rotatably mounted on the surface of the limiting shaft 212. The speed change gear 3 216 is fixedly mounted on the back of the speed change gear 2 215 and meshes with the speed change gear 1 214. The speed change gear 4 217 is rotatably mounted on the front side of the linear motor mover 2 and is located on the side of the speed change gear 2 215 away from the speed change gear 1 214. The speed change gear 4 217 meshes with the speed change gear 2 215. The third helical tooth 2171 is fixedly mounted on the front side of the speed change gear 4 217.

[0040] The second bevel tooth 2132 can be driven to rotate by the first bevel tooth 2131, and drive the speed gear 1 214 to rotate at the same time. When the speed gear 1 214 rotates, it can drive the speed gear 3 216 meshing therewith to rotate. After the speed gear 3 216 rotates, it drives the speed gear 2 215 to rotate. The speed gear 2 215 drives the speed gear 4 217 to rotate. The speed gear 4 217 rotates and drives the third bevel tooth 2171 to rotate. The rotation of the third bevel tooth 2171 drives the rotating reciprocating switching component to drive and realize the drive conversion.

[0041] refer to Figure 3 and Figure 4 The rotary reciprocating switching assembly includes a fourth bevel gear 2172, a stabilizing frame 2173, a driven shaft 2174, a belt gear 1 2175, a transmission belt 2176 and a belt gear 2 2177. The fourth bevel gear 2172 is meshed with the top of the third bevel gear 2171. The stabilizing frame 2173 is fixedly installed on the front side of the linear motor mover 2 and is located on the top of the speed change gear 4 217. The driven shaft 2174 is rotatably installed inside the stabilizing frame 2173. The belt gear 1 2175 is fixedly installed on the top of the driven shaft 2174. The transmission belt 2176 is sleeved on the surface of the belt gear 1 2175. The belt gear 2 2177 is rotatably installed on the side of the top of the linear motor mover 2 away from the circulating water tank 3. The belt gear 2 2177 is installed through the transmission belt 2176 and the belt gear 1 2175. The top of the belt gear 2 2177 is fixedly installed on the bottom of the driving disk 22.

[0042] The third bevel gear 2171 can drive the fourth bevel gear 2172 to rotate. After the fourth bevel gear 2172 rotates, it drives the driven shaft 2174 which is rotationally limited by the stabilizing frame 2173 to rotate. The driven shaft 2174 drives the belt gear 1 2175 to rotate. After the belt gear 1 2175 rotates, it can drive the belt gear 2 2177 to rotate via the transmission belt 2176. After the belt gear 2 2177 rotates, it drives the driving disk 22 to rotate to perform a reciprocating drive operation.

[0043] refer to Figure 1The front and rear sides of the top of the circulating water tank 3 are fixedly inlaid with semiconductor refrigeration sheets 5, and the cold surface of the semiconductor refrigeration sheets 5 is in contact with the inner wall of the circulating water tank 3; as a technical optimization scheme of the present invention, the semiconductor refrigeration sheets 5 can keep the liquid inside the circulating water tank 3 at a low temperature after being started, ensuring that the liquid remains at a low temperature after multiple cycles.

[0044] The multi-faceted synchronous cooling assembly is disposed inside the cooling block 4 and is used to remove the heat from the linear motor core 45 and the copper coil 46; Figure 8 The multi-faceted synchronous cooling assembly includes a cooling pipe 47, a cooling block 2 41, a cooling block 3 42, a water inlet pipe 43 and a water return pipe 44. The cooling block 2 41 and the cooling block 3 42 are fixedly installed on both sides of the cooling block 1 4, respectively. The interiors of the cooling blocks 1 4, 2 41 and 3 42 are all provided with slots that match the cooling pipe 47, and the cooling pipe 47 passes through the cooling blocks 2 41, 1 4 and 3 42 to form a cooling whole. One end of the water inlet pipe 43 is connected to the cooling pipe 47, and the other end of the water inlet pipe 43 is connected to the cooling pipe 47. One end passes through the linear motor mover 2 and is connected to the front side of the circulating water tank 3, one end of the return pipe 44 is connected to the cooling pipe 47, and the other end passes through the linear motor mover 2 and is connected to the back side of the circulating water tank 3. The cooling pipe 47 can facilitate liquid guided circulation through the return pipe 44 and the water inlet pipe 43. At the same time, the cooling block 2 41 and the cooling block 3 42 can cooperate with the cooling block 1 4 and the cooling pipe 47 to form a cooling whole, so as to cool the linear motor core 45 and the copper coil 46 over a large area.

[0045] refer to Figure 2 and Figure 3 The driven component includes a linkage gear 2133 and a linkage tooth plate 2134. The linkage gear 2133 is fixedly installed at the bottom of the driving shaft 213. The linkage tooth plate 2134 is fixedly installed on the side of the linear motor stator 1 close to the linkage gear 2133 and meshes with the linkage gear 2133. When the linkage gear 2133 is meshed with the linkage tooth plate 2134, it can realize self-rotation through the reaction force while the linear motor mover 2 moves, and the self-rotation speed changes according to the moving speed of the linear motor mover 2, so that the cooling cycle speed can be adapted to the synchronous driving speed to ensure the speed of taking away heat during cooling. Compared with the existing technology, there is no need to actively adjust the pump body.

[0046] The working principle and use process of the present invention are as follows: when in use, the linear motor mover 2 is driven, and then the gear frame 211 is driven to follow the movement through the cooperation of the protective side cover 21, so that the gear frame 211 limits the driving shaft 213 and the linkage gear 2133. When the linkage gear 2133 is meshed with the linkage gear plate 2134, it can realize self-rotation through the reaction force while the linear motor mover 2 moves, and the self-rotation speed changes according to the moving speed of the linear motor mover 2, and then the cooling cycle speed can be adapted to the synchronous driving speed to ensure the speed of taking away heat during cooling;

[0047] When the driving shaft 213 rotates, it can drive the first bevel gear 2131 to rotate, and the second bevel gear 2132 can be driven to rotate by the first bevel gear 2131, and at the same time drive the speed gear 1 214 to rotate. When the speed gear 1 214 rotates, it can drive the speed gear 3 216 meshing with it to rotate. After the speed gear 3 216 rotates, it drives the speed gear 2 215 to rotate. The speed gear 2 215 then drives the speed gear 4 217 to rotate, and then the speed gear 4 217 rotates to drive the third bevel gear 2171 to rotate. The third bevel gear 2171 can drive the fourth bevel gear 2172 to rotate. After the fourth bevel gear 2172 rotates, it drives the driven shaft 2174 limited by the stabilizing frame 2173 to rotate. The driven shaft 2174 drives the belt gear 1 2175 to rotate. After the belt gear 1 2175 rotates, it can drive the belt gear 2 2177 to rotate through the transmission belt 2176. After the belt gear 2 2177 rotates, it drives the driving disk 22 to rotate.

[0048] After the driving disc 22 is driven to rotate, the sliding column 224 is driven to rotate. When the sliding column 224 rotates, the driving frame 222 that slides with it moves back and forth under the limit of the guide frame 221, and at the same time drives the pushing frame 223 to push back and forth, thereby driving the piston rod 225 to drive back and forth. The piston rod 225 can drive the piston block 31 to move back and forth to realize the operation of circulating water pumping; the reciprocating operation steps are as follows:

[0049] The piston block 31 can pump water under negative pressure by sliding left and right. Before pumping water, the interior of the circulating water tank 3 needs to be filled with liquid. When the piston block 31 moves to the right, the sealing block 35 at the second water inlet 33 on the right is squeezed by the liquid negative pressure to discharge the liquid from the right wall. At the same time, the sealing block 35 at the first water inlet 32 ​​on the left is retracted into the pumping chamber. Under negative pressure, the liquid enters the left side of the pumping chamber. Then, when the piston block 31 moves to the left, the liquid just filled in the left side of the pumping chamber is discharged from the second water inlet 33 on the left under negative pressure. At the same time, the sealing block 35 at the first water inlet 32 ​​on the left is retracted into the pumping chamber. Under negative pressure, the liquid enters the left side of the pumping chamber. Negative pressure pumping is performed at 32, and the liquid pushes open the sealing block 35 at the first water inlet 32 ​​on the right side and enters the right side of the pumping chamber to perform a new round of pumping. Multiple cycles are performed in sequence to achieve repeated pumping, and the sealing block 35 that is pushed open each time can be reset and sealed again by the tension of the tension spring 34. When the front side of the circulating water tank 3 needs to be pumped, the liquid flows into the interior of the cooling pipe 47 through the back side of the circulating water tank 3 through the return pipe 44, so that the cooling liquid in the cooling pipe 47 enters the interior of the circulating water tank 3 again through the water inlet pipe 43 after being cooled as a whole, thereby realizing the entire cooling cycle.
