[0002] Industrial robotic arms are the cornerstone of modern manufacturing. They are programmable, multi-functional automated machines used to move materials, parts, tools, or specialized devices in industrial environments, accomplishing various tasks through variable programming. Motors are mounted on the robotic arms for easy control of their rotation. However, these motors can generate high temperatures during operation, which can affect their performance.

[0003] A search revealed a Chinese patent with application number "CN201810045527.4", specifically concerning a motor shaft and an evaporative cooling shaft-type oil-cooled motor. The motor includes a shaft body with an internal cavity, divided into an evaporation section and a condensation section from the middle to the ends. The evaporative cooling shaft-type oil-cooled motor includes a housing, a front cover, a rear cover, a stator, a rotor, and a shaft.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] This invention provides the following technical solutions: Example 1 Please see Figure 1 - Figure 6A dual-channel cooling shaft for an industrial robotic arm motor includes a housing 1, a cover plate 3 fixedly connected to the left side of the housing 1, a cooling unit 8 disposed inside the housing 1, the cooling unit 8 including an inner housing 81 fixedly connected to the inside of the housing 1, a stator 9 disposed inside the inner housing 81, a rotor 10 disposed inside the stator 9, an output shaft 2 fixedly connected to the inner side of the rotor 10, an oil inlet pipe 87 fixedly connected to the upper side of the inner housing 81, an oil outlet pipe 89 fixedly connected to the lower side of the inner housing 81, a cooling chamber 82 fixedly connected to the outer side of the housing 1, and a circulation assembly 83 disposed inside the cooling chamber 82 for circulating cooling oil. During use, the rotor 10 drives the output shaft 2 to rotate, facilitating the operation of the robotic arm motor. A fixed pipe 811 is fixedly connected between the oil inlet pipe 87 and the cooling chamber 82. Valves 88 are installed on both the upper and lower sides of the fixed pipe 811 on the outer side of the oil inlet pipe 87. An oil inlet groove 84 and an oil collection groove 86 are opened on the inner wall of the inner shell 81. Multiple cooling grooves 85 are opened on the inner wall of the inner shell 81 between the oil inlet groove 84 and the oil collection groove 86. The oil inlet pipe 87 is connected to the oil inlet groove 84, and the oil outlet pipe 89 is connected to the oil collection groove 86. When the motor is in use, cooling oil is introduced into the inner shell 81 through the oil inlet pipe 87, and distributed to the multiple cooling grooves 85 on both sides through the oil inlet groove 84. The flowing cooling oil cools the stator 9 and rotor 10. Finally, under the action of gravity, the cooling oil falls into the oil collection groove 86 and is discharged through the oil outlet pipe 89. When the motor is in operation, the output shaft 2 drives the pump body impeller. When plate 834 rotates, under the action of negative pressure, the cooling oil discharged by connecting pipe 836 is drawn into fixed cylinder 831 and then introduced into cooling chamber 82 through connecting pipe 837. Cooling chamber 82 contains cooling oil. When the cooling oil enters cooling chamber 82, under the action of fixed pipe 811 and oil inlet pipe 87 (where lower valve 88 is opened, valve 88 is a solenoid valve), the cooling oil can be reused in inner shell 81 through oil inlet pipe 87, so that the cooling oil can be recycled. During recycling, external water inlet pipe 8316 is connected to water pump, which introduces cold water into spiral heat exchange tube 8315 and discharges cold water through water outlet pipe 8317, so that the cooling oil in cooling chamber 82 in heat exchange tube 8315 is cooled down, which facilitates the recycling of cooling oil.

[0021] The circulation assembly 83 includes a heat exchange tube 8315, which is fixedly connected to the inside of the cooling chamber 82. A fixing cover 6 is fixedly connected to the right side of the cooling chamber 82, and a fixing cylinder 831 is fixedly connected to the right side of the fixing cover 6. The right end of the output shaft 2 is located inside the fixing cylinder 831 and is fixedly connected to multiple pump blades 834. A connecting pipe 836 is fixedly connected between the fixing cylinder 831 and the oil outlet pipe 89, and a connecting pipe 837 is fixedly connected between the fixing cylinder 831 and the cooling chamber 82. A water inlet pipe 8316 is fixedly connected to the right side of the heat exchange tube 8315. A water outlet pipe 8317 is fixedly connected to the left side of the cooling chamber 82. The outer ends of the water inlet pipe 8316 and the water outlet pipe 8317 both pass through the outer side of the cooling chamber 82. The heat exchange pipe 8315 has a spiral structure. Support plates 7 are fixedly connected to the outer sides of the fixed cover 6 and the heat dissipation shell 4. When it is necessary to drain the cooling oil in the cooling chamber 82, the motor is first flipped over. The oil outlet pipe 89 is connected to the connecting pipe 836 through a flange. The connecting pipe 836 is separated from the oil outlet pipe 89. The motor is controlled to reverse and the two valves 88 are closed so that the cooling oil in the cooling chamber 82 is drained from the connecting pipe 836, which facilitates the replacement of the cooling oil.

[0022] Fixed cylinder 2 832 is fixedly connected to the right side of fixed cylinder 1 831. Multiple air inlets 833 are opened on the outside of fixed cylinder 2 832. The right end of output shaft 2 passes through the outside of fixed cylinder 1 831 and is fixedly connected to multiple fan blades 835. Heat sink 4 is fixedly connected to the outside of housing 1. Air supply pipe 810 is fixedly connected between fixed cylinder 2 832 and heat sink 4. Heat sink 4 has heat dissipation holes 5 on its outside. When the motor is running, output shaft 2 drives fan blades 835 to rotate, and external airflow enters fixed cylinder 2 832 through air inlets 833. The airflow is then passed into heat sink 4 through air supply pipe 810 and discharged through heat dissipation holes 5, which facilitates the airflow to dissipate heat from the motor housing 1 and achieves the effect of dual-channel cooling.

A guide block 8327 is slidably connected to the outer side of the guide plate 8326. A toothed plate 8328 that meshes with the gear component 8325 is fixedly connected to the lower side of the guide block 8327.

A rotating rod 839 is rotatably connected to the outer side of the fixing block 838. A bevel gear 8310 that meshes with the bevel gear 8311 is fixedly connected to the lower end of the rotating rod 839. A bevel gear 8312 is fixedly connected to the upper end of the rotating rod 839. A control lever 8314 is rotatably connected to the outside of the cooling cavity 82. A bevel gear 8313 that meshes with bevel gear 8312 is fixedly connected to the right end of the control lever 8314. A gear 8318 that meshes with gear ring 8319 is fixedly connected to the left end of the control lever 8314. A protrusion 8321 and a stop rod 8338 limit the connection.

[0024] When the motor is running, the output shaft 2 drives the second bevel gear 8311 to rotate, the second bevel gear 8311 drives the first bevel gear 8310 to rotate, the first bevel gear 8310 drives the rotating rod 839 to rotate, the rotating rod 839 drives the third bevel gear 8312 to rotate, the third bevel gear 8312 drives the fourth bevel gear 8313 to rotate, the fourth bevel gear 8313 drives the control lever 8314 to rotate, the control lever 8314 drives the first gear component 8318 to rotate, the first gear component 8318 drives the gear ring 8319 to rotate, the gear ring 8319 drives the rotating ring 8320 to rotate, the rotating ring 8320 drives the protrusion 8321 to rotate. Under the action of the spring force 8335, the protrusion 8321 drives the abutment rod 8338 to move up and down. The push rod 8338 drives the guide block 8333 to move up and down repeatedly. The guide block 8333 drives the inclined plate 8331 to swing repeatedly. The inclined plate 8331 drives the moving rod 8329 to move left and right repeatedly.

[0025] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0026] Working Principle: During operation, the operator first introduces cooling oil into the inner shell 81 through the oil inlet pipe 87. The oil inlet groove 84, cooling groove 85, and oil collection groove 86 facilitate cooling of the stator 9 and rotor 10. The cooling oil is then discharged through the oil outlet pipe 89. When the motor is running, the output shaft 2 drives the pump body blades 834 to rotate. Through the connecting pipes 836 and 837, cooling oil is introduced into the cooling chamber 82. Simultaneously, cold water is introduced into the heat exchange tubes 8315 through the water inlet pipe 8316. The cold water is discharged through the water outlet pipe 8317, facilitating cooling of the cooling oil. The cooling oil is then easily reintroduced into the inner shell 81 through the fixed pipe 811 and the oil inlet pipe 87, promoting the circulation of the cooling oil. Simultaneously, the output shaft 2 drives the second bevel gear 8311 to rotate, which in turn drives the first bevel gear 8310 to rotate. The first bevel gear 8310... The rotating rod 839 rotates, and under the action of bevel gear three 8312, bevel gear four 8313, control rod 8314 and gear component one 8318, gear component one 8318 drives gear ring 8319 to rotate. Gear ring 8319 drives the protrusion 8321 on rotating ring 8320 to rotate. Under the action of push rod 8338, guide block two 8333, inclined plate 8331 and moving rod 8329, the tooth plate 8328 on guide block one 8327 is controlled to move left and right repeatedly. Tooth plate 8328 drives gear component two 8325 to rotate forward and reverse repeatedly. Gear component two 8325 drives swing rod 8323 to rotate. Swing rod 8323 drives swing plate 8324 to swing, which facilitates the swing plate 8324 to stir the cooling oil and increase the cooling effect of the cooling oil. At the same time, the output shaft 2 drives the fan blade 835 to rotate, which, under the action of air pipe 810 and heat sink 4, facilitates the cooling of motor housing 1.
