Description

Technical Field

[0001] The utility model relates to the technical field of tool turret heat dissipation, in particular to a heat dissipation structure for a servo power tool turret. Background Art

[0002] All automated processing of mechanical precision parts is inseparable from CNC lathes. CNC lathes are common equipment in the domestic and foreign mechanical processing industries and are widely used. The core component of a CNC lathe is the tool turret. Through the turning tools clamped on the tool turret, the lathe can cooperate with the numerical control system to complete various turning processing processes. Its usage rate ranks first among all machining equipment. It is controlled by a computer program, has strong automation performance, and can control a series of actions such as the tool turret, feed rate, feed time, and tool change.

[0003] A patent with the publication number CN 110052630 B discloses a servo power tool turret, including a first installation box. A locking mechanism is provided on one side of the first installation box, and a second installation box is provided on the locking mechanism. A servo motor is fixed at the bottom end inside the first installation box. A first synchronous pulley is fixed on the output shaft of the servo motor. The first synchronous pulley is drivingly connected to a second synchronous pulley. The second synchronous pulley is fixed at the end of the input shaft of the divider. Through the above structure, protection for the servo motor and the divider is achieved during heavy-duty cutting. The structure is simple, easy to operate, improves the wear resistance of the equipment, and extends the service life. However, for existing servo power tool turrets.

[0004] The tool turrets of CNC lathes are divided into two types: hydraulic and servo. The former is a traditional one that uses hydraulic oil as power for tool change, and the latter changes the power for tool change from hydraulic to a servo motor based on the former. However, to prevent extremely high temperatures from being generated inside the tool turret during long-term use, a high-pressure air pump is installed outside the servo power tool turret to inject air into the inside of the servo power tool turret to quickly cool it. However, the air blown by the high-pressure air pump carries a lot of impurities, and these impurities will accumulate inside the servo machine. Moreover, the air around the servo machine will dissipate due to the temperature of the servo machine, resulting in a temperature increase. These high-temperature gases will be re-absorbed into the inside of the servo machine by the high-pressure air pump, leading to the problem of slow heat dissipation inside the servo machine. Summary of the Utility Model

[0005] Therefore, the technical problem to be solved by the present utility model is to overcome the problem in the prior art that when the high-pressure air pump forcibly injects external air into the servo machine, the temperature inside the servo machine is squeezed and discharged under strong gas convection, and the surrounding air will dissipate due to the temperature of the servo machine, resulting in a temperature increase. These high-temperature gases will be re-absorbed into the inside of the servo machine by the high-pressure air pump, leading to the problem of slow heat dissipation inside the servo machine.

[0006] To solve the above technical problems, the present utility model provides a servo power turret heat dissipation structure, which includes a servo motor and a servo tool detachably installed on the outer surface of the output end of the servo motor, a limit sleeve two detachably installed on the outer surface of the servo motor, and a condenser detachably installed on the outer surfaces of the limit sleeve two and the servo motor. A limit rod is movably sleeved on the inner wall surface of the limit sleeve two. One end of the limit rod is fixedly connected with a transmission wheel that is movably lapped on the outer surface of the transmission collar. A transmission track is movably sleeved on the outer surface of the limit rod and is arranged on one surface of the transmission wheel. The other surface of the transmission track is movably sleeved with a transmission snap ring. One end of the transmission snap ring is movably sleeved with a cold air diversion pipe arranged on the outer surface of the servo motor. A multi-angle air guide cylinder extending to the inner wall surface of the servo motor is fixedly connected to the outer surface of the cold air diversion pipe.

[0007] In an embodiment of the present utility model, a return air pipe extending to the inner wall surface of the servo motor is fixedly connected to the input end of the condenser, and a drainage pipe is fixedly connected to the output end of the condenser; a transmission collar is fixedly installed on the outer surface of the servo tool.

[0008] In an embodiment of the present utility model, the other end of the drainage pipe extends to the inner wall surface of the cold air diversion pipe, and a second transmission rod movably sleeved on the inner wall surface of the cold air diversion pipe is fixedly connected to one end of the cold air diversion pipe.

[0009] In an embodiment of the present utility model, a filter plate is arranged on the inner wall surface of the cold air diversion pipe and at the edge position of one end of the drainage pipe.

[0010] In an embodiment of the present utility model, the second transmission rod is movably lapped on the outer surface of the filter plate, and a fan blade is fixedly connected to the outer surface of the filter plate.

[0011] In an embodiment of the present utility model, a first transmission rod is fixedly connected to the output end of the servo motor, and the other end of the first transmission rod is fixedly connected to the outer surface of the servo tool.

[0012] In an embodiment of the present utility model, a limit sleeve one is fixedly connected to the outer surface of the servo tool and is arranged on the inner wall surface of the transmission collar.

[0013] In an embodiment of the present utility model, a cavity is arranged between the limit sleeve one and the first transmission rod, and the outer surface of the limit sleeve one is movably sleeved on the outer surface of the servo motor.

[0014] The above technical solution of the present utility model has the following advantages compared with the prior art:

[0015] The utility model discloses a servo power turret heat dissipation structure. When the servo machine rotates the transmission rod 1 to drive the servo knife, the transmission ring on the outer surface of the servo knife cooperates with the transmission wheel on one end of the limit rod to perform reverse transmission, so that the transmission track on the outer surface of the limit rod drives the transmission rod 2 on the outer surface of the cold air guide pipe to rotate. When the transmission rod 2 rotates, the gas inside the cold air guide pipe is pushed to the tail end of the cold air guide pipe. The gas accumulated at the tail end of the cold air guide pipe is injected into the interior of the servo machine through the multi-angle air guide cylinder on the outer surface of the cold air guide pipe. The low-temperature airflow of the multi-angle air guide cylinders on both sides of the servo machine is used for counteraction, and the residual heat source inside the servo machine is squeezed into the interior of the return air pipe, and then the hot air inside the return air pipe is subjected to low-temperature cooling treatment through the condenser.

[0016] The utility model discloses a servo power turret heat dissipation structure. When the gas inside the cold air guide pipe is continuously infused into the servo machine, a low pressure is formed at the entrance of the cold air guide pipe. Under the change of air pressure, the gas inside the discharge pipe is absorbed into the cold air guide pipe. The gas absorption of the discharge pipe infuses the low-temperature gas inside the condenser into the cold air guide pipe, so that the gas is always in a gas flow state. The circulation of the airflow can effectively reduce the infiltration of external gas and greatly isolate the effect of dust infiltration.

[0017] The utility model discloses a servo power turret heat dissipation structure. When the low-temperature gas inside the servo machine is continuously accumulated, the low-temperature gas will penetrate into the interior of the servo knife through the gap between the transmission rod 1 and the limiting sleeve 1, and the interior of the servo knife will be quickly cooled down by the excess low-temperature gas. After the excess low-temperature cold air leaks out from the gap between the limiting sleeve 1 and the transmission rod 1, the excess low-temperature gas will have a secondary cooling effect on the servo knife and the gas around the servo machine.

Specific embodiments

[0025] The present utility model will be further described below in conjunction with the attached drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the specific embodiments cited do not limit the present utility model.

[0026] Referring to Figure 1 - Figure 5 As shown, a servo power turret heat dissipation structure of the present utility model includes a servo motor 11 and a servo tool 12 detachably installed on the outer surface of the output end of the servo motor 11, a second limit sleeve 13 detachably installed on the outer surface of the servo motor 11, a condenser 14 detachably installed on the outer surfaces of the second limit sleeve 13 and the servo motor 11. A return air pipe 141 extending to the inner wall surface of the servo motor 11 is fixedly connected to the input end of the condenser 14, and a drainage pipe 142 is fixedly connected to the output end of the condenser 14; a transmission collar 121 is fixedly installed on the outer surface of the servo tool 12; a limit rod 131 is movably sleeved on the inner wall surface of the second limit sleeve 13. One end of the limit rod 131 is fixedly connected to a transmission wheel 132 that is movably lapped on the outer surface of the transmission collar 121. A transmission track 133 disposed on one surface of the transmission wheel 132 is movably sleeved on the outer surface of the limit rod 131. A transmission snap ring 134 is movably sleeved on the other surface of the transmission track 133. One end of the transmission snap ring 134 is movably sleeved on a cold air diversion pipe 135 disposed on the outer surface of the servo motor 11. The other end of the drainage pipe 142 extends to the inner wall surface of the cold air diversion pipe 135. A multi-angle air guide cylinder 136 extending to the inner wall surface of the servo motor 11 is fixedly connected to the outer surface of the cold air diversion pipe 135. A second transmission rod a1 movably sleeved on the inner wall surface of the cold air diversion pipe 135 is fixedly connected to one end of the cold air diversion pipe 135;

[0027] When the servo 11 rotates the transmission rod 123 to drive the servo knife 12, the transmission ring 121 on the outer surface of the servo knife 12 performs reverse transmission on the transmission wheel 132 on one end of the limit rod 131, so that the transmission track 133 on the outer surface of the limit rod 131 drives the transmission rod 2 a1 on the outer surface of the cold air guide tube 135 to rotate. When the transmission rod 2 a1 rotates, the gas inside the cold air guide tube 135 is pushed to the tail end of the cold air guide tube 135. The gas accumulated at the tail end of the cold air guide tube 135 will pass through the multi-angle air guide tube 136 on the outer surface of the cold air guide tube 135 and be injected into the interior of the servo 11. The low temperature of the multi-angle air guide tube 136 on both sides of the servo 11 is used to The airflows are counteracted, and the residual heat source inside the servo 11 is squeezed into the return air pipe 141, and then the hot air inside the return air pipe 141 is cooled by the condenser 14; when the gas inside the cold air guide pipe 135 is continuously infused into the servo 11, a low pressure is formed at the entrance of the cold air guide pipe 135. Under the change of air pressure, the gas inside the discharge pipe 142 is absorbed into the cold air guide pipe 135, and the gas absorption of the discharge pipe 142 will infuse the low-temperature gas inside the condenser 14 into the cold air guide pipe 135, so that the gas is always in a state of gas flow. The recycling of airflow can effectively reduce the infiltration of external gas and greatly isolate the effect of dust penetration.

[0028] Reference Figure 1 - Figure 5 As shown, in one embodiment of the utility model, a filter plate a2 is provided on the inner wall surface of the cold air guide pipe 135 and at the edge position of one end of the discharge pipe 142, the outer surface of the transmission rod a1 is movably overlapped on the outer surface of the filter plate a2, and the outer surface of the filter plate a2 is fixedly connected with a fan blade a3, and the output end of the servo 11 is fixedly connected with a transmission rod 123, and the other end of the transmission rod 123 is fixedly connected to the outer surface of the servo knife 12, and the outer surface of the servo knife 12 is fixedly connected with a limiting sleeve 122 arranged on the inner wall surface of the transmission ring 121, and a cavity is provided between the limiting sleeve 122 and the transmission rod 123, and the outer surface of the limiting sleeve 122 is movably sleeved on the outer surface of the servo 11;

[0029] When the low-temperature gas inside the servo motor 11 continues to accumulate, the low-temperature gas will penetrate into the interior of the servo knife 12 through the gap between the transmission rod 123 and the limiting sleeve 122, and the excess low-temperature gas will be used to quickly cool the inside of the servo knife 12. After the excess low-temperature cold air leaks out from the gap between the limiting sleeve 122 and the transmission rod 123, the excess low-temperature gas will have a secondary cooling effect on the servo knife 12 and the gas around the servo motor 11.

[0030] Working principle: When the servo motor 11 rotates the transmission rod 123 to drive the servo knife 12, the transmission ring 121 on the outer surface of the servo knife 12 performs reverse transmission on the transmission wheel 132 on one end of the limit rod 131, so that the transmission track 133 on the outer surface of the limit rod 131 drives the transmission rod 2 a1 on the outer surface of the cold air guide tube 135 to rotate. When the transmission rod 2 a1 rotates, the gas inside the cold air guide tube 135 is directed to the cold air guide tube 135. The tail end of the air guide pipe 135 pushes the gas, and the gas accumulated at the tail end of the cold air guide pipe 135 will pass through the multi-angle air guide cylinder 136 on the outer surface of the cold air guide pipe 135 and be injected into the inside of the servo 11. The low-temperature airflow of the multi-angle air guide cylinder 136 on both sides of the servo 11 is used to offset the residual heat source inside the servo 11 and squeeze it into the inside of the return air pipe 141. Then, the condenser 14 is used to cool the hot air inside the return air pipe 141.

[0031] When the gas in the cold air guide pipe 135 is continuously infused into the servo 11, a low pressure is formed at the entrance of the cold air guide pipe 135. Under the change of pressure, the gas in the discharge pipe 142 is absorbed into the cold air guide pipe 135. The gas absorption of the discharge pipe 142 will infuse the low-temperature gas in the condenser 14 into the cold air guide pipe 135, so that the gas is always in a state of gas flow. The circulation of the air flow can effectively reduce the infiltration of external gas and greatly isolate the effect of dust penetration.

[0032] When the low-temperature gas inside the servo motor 11 continues to accumulate, the low-temperature gas will penetrate into the interior of the servo knife 12 through the gap between the transmission rod 123 and the limiting sleeve 122, and the excess low-temperature gas will be used to quickly cool the inside of the servo knife 12. After the excess low-temperature cold air leaks out from the gap between the limiting sleeve 122 and the transmission rod 123, the excess low-temperature gas will have a secondary cooling effect on the servo knife 12 and the gas around the servo motor 11.

[0033] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the protection scope of the invention of the utility model.
