[0001] The present application relates to the technical field of machining machine tools, and in particular to a drive module, machining equipment and machining machine tools. Background Art

[0002] CNC machine tools are automated machine tools equipped with a program control system. With the upgrading of industries, the requirements of the electronic 3C, automobile and home appliance industries are getting higher and higher, and the requirements for mold precision are getting higher and higher. CNC machine tools that can achieve one-time finishing are becoming more and more popular, and their market demand is also constantly expanding.

[0003] The structure of a CNC machine tool usually includes a processing device and a machine tool body for installing the processing device. The processing device is used to achieve the fine processing of the mold. The processing device realizes the workmanship through a drive module. The drive module includes a motor and a screw rod connected to the drive end of the motor.

[0004] In the above structure, during the process of mold processing by the processing equipment, a large amount of heat generated by the long-term operation of the motor cannot be taken away, resulting in large thermal deformation.

At the same time, the bearing supporting the screw rod will also generate heat during rotation, and its heat will also be transmitted to the bearing seat. Both the motor seat and the bearing seat are castings and are directly installed on the bed, which will cause the bed to heat up, causing the bed column saddle to be easily deformed, seriously affecting the processing accuracy.

[0044] CNC machine tools are automated machine tools equipped with a program control system. With the upgrading of industries, the requirements of the electronic 3C, automobile and home appliance industries are getting higher and higher, and the requirements for mold precision are getting higher and higher. CNC machine tools that can achieve one-time finishing are becoming more and more popular, and their market demand is also constantly expanding.

[0045] The structure of a CNC machine tool generally includes a processing device and a machine tool body for installing the processing device. The processing device realizes the fine processing of the mold through a drive module, and the drive module includes a motor and a screw rod matched with a drive end 1 of the motor.

[0046] In the above structure, during the process of mold processing by the processing equipment, a large amount of heat generated by the long-term operation of the motor cannot be taken away, resulting in large thermal deformation. The heat generated by the motor will also be transmitted to the motor seat. At the same time, the bearing supporting the screw rod will also generate heat during rotation, and its heat will also be transmitted to the bearing seat. Both the motor seat and the bearing seat are castings and are directly installed on the bed, which will cause the bed to heat up, causing the bed column saddle to be easily deformed, seriously affecting the processing accuracy.

[0047] In the prior art, although there are some motor seats with cooling functions to cool the drive module, the effect is still not ideal and the heat dissipation efficiency is slow.

[0048] Based on the above considerations, in order to solve the above problems, please refer to Figures 1 to 3. A drive module 100 is provided in one or more embodiments of the present application. A first cooling channel 161 is formed in the screw rod 16, and a second cooling channel 173 is formed in the motor 17, so that the first cooling channel 161 is connected with the second cooling channel 173, thereby realizing integrated cooling of the screw rod 16 and the motor 17, and effectively improving the heat dissipation efficiency.

[0049] Specifically, the drive module 100 includes a bearing seat 10, a bearing 11, a screw 16, a motor 17 and a motor seat 15. The bearing seat 10 is connected to the machine tool body, and the bearing 11 is connected to the bearing seat 10. One end of the screw 16 along its longitudinal direction is connected to the bearing seat 10, and a first cooling channel 161 is formed in the screw 16 and runs through the longitudinal direction. The motor 17 includes a body 171 and a driving end 172 connected to the body 171, and a second cooling channel 173 is formed in the motor 17 and runs through the driving end 172 and the body 171. The driving end 172 is coaxially connected to the other end of the screw 16 along its longitudinal direction, and the first cooling channel 161 is connected to the second cooling channel 173. The motor seat 15 is connected between the bearing seat 10 and the motor 17, and the screw 16 is movably arranged in the motor seat 15.

[0050] It can be understood that after the screw rod 16 and the driving end 172 of the motor 17 are assembled, the first cooling channel 161 is connected to the second cooling channel 173, and the liquid inlet of either the first cooling channel 161 or the second cooling channel 173 is connected to the cooling source, so that the coolant can flow through the first cooling channel 161 and the second cooling channel 173, and finally be discharged from the liquid outlet of the other. In this way, the coolant can take away the heat generated by the screw rod 16 and the motor 17 when they are working through heat exchange, and realize the integrated cooling of the screw rod 16 and the motor 17, effectively improving the heat dissipation efficiency.

[0051] In some embodiments, referring to FIG1 , the driving module 100 further includes a rotary joint 12, which is movably connected to the body 171 and located at the opening of the second cooling channel 173 in the body 171. The rotary joint 12 is used to connect to a pipe connected to the second cooling channel 173.

[0052] It is understandable that during the operation of the drive module 100, the rotary joint 12 can rotate relative to the body 171 of the motor 17, thereby avoiding interference between the external pipeline and the motor 17 to ensure smooth flow of the coolant, which is conducive to the integrated cooling of the screw 16 and the motor 17.

[0053] In some embodiments, referring to FIG. 1 and FIG. 2 , the drive module 100 further includes a rigid coupling 18 , a through installation cavity 181 is formed in the rigid coupling 18 , and a connection between the drive end 172 and the screw rod 16 is penetrated in the installation cavity 181 .

[0054] It is understandable that during the process of the processing equipment realizing mold processing, the driving end 172 and the screw 16 will be heated and expanded due to the large amount of heat generated by high-speed operation, and it is easy to cause deviations in the assembly accuracy of the driving end 172 and the screw 16, thereby causing structural damage. The present application realizes a rigid connection between the driving end 172 and the screw 16 through a rigid coupling 18 to avoid deviations in the assembly of the driving end 172 and the screw 16, which is beneficial to prolonging the service life of the product and ensuring the normal operation of the drive module 100.

[0055] Furthermore, one end of the motor seat 15 is fixedly connected to one end of the motor 17 close to the screw rod 16 , and the other end of the motor seat 15 is detachably connected to one end of the bearing seat 10 close to the screw rod 16 .

[0056] It is understandable that, since the rigid coupling 18 realizes the rigid connection between the driving end 172 and the screw rod 16, the driving end 172 and the screw rod 16 are not easily offset. Therefore, the driving end 172 and the screw rod 16 need to be coaxially assembled with high precision.

[0057] The present application provides a detachable connection between the motor seat 15 and the bearing seat 10 , so that the user can flexibly control the movement of the motor 17 to adjust the assembly accuracy of the driving end 172 and the screw rod 16 .

[0059] It is understandable that, in the present application, the matching portion 151 is a threaded hole opened on the motor seat 15, and the adjusting member is a top screw. The user can adjust the assembly accuracy of the driving end 172 and the screw rod 16 by adjusting the position of the top screw in the threaded hole.

[0060] In some embodiments, referring to FIG. 1 and FIG. 2 , the driving module 100 further includes a seal 13, and a seal groove 182 extending along the circumference of the mounting cavity 181 is formed on the inner wall thereof, and the seal 13 is at least partially embedded in the seal groove 182. In this way, the seal groove 182 can improve the stability of the seal 13 assembly to prevent the seal 13 from falling out.

[0061] Furthermore, the portion of the seal 13 protruding from the seal groove 182 is in sealing contact with the screw 16 and / or the drive end 172. The seal 13 can seal the connection between the screw 16 and the drive end 172 to prevent leakage of the coolant.

[0062] In some embodiments, referring to Figures 1 and 2, there are multiple sealing grooves 182, and all of the sealing grooves 182 are spaced apart along the inner wall of the mounting cavity 181, the connection between the driving end 172 and the screw rod 16 is located between any two adjacent sealing grooves 182, and the seals 13 in the two adjacent sealing grooves 182 are respectively sealed against the screw rod 16 and the driving end 172.

[0063] It is understandable that the seals 13 disposed on both sides of the connection between the driving end 172 and the screw rod 16 cooperate with each other to achieve sealing of the connection between the screw rod 16 and the driving end 172 to prevent leakage of coolant.

[0064] In some embodiments, referring to FIG. 1 and FIG. 3 , the driving module 100 further includes a mounting member 14 , and the mounting member 14 is detachably connected between the motor seat 15 and the bearing seat 10 .

The bearing seat is connected to the machine tool body, and the bearing is connected to the bearing seat. One end of the screw along its longitudinal direction is connected to the bearing seat, and a first cooling channel is formed in the screw along its longitudinal direction. The motor includes a body and a driving end connected to the body, and a second cooling channel is formed in the motor that runs through the driving end and the body. The driving end is coaxially connected to the other end of the screw along its longitudinal direction, and the first cooling channel is connected to the second cooling channel. The motor seat is connected between the bearing seat and the motor, and the screw is movably arranged in the motor seat. After the screw rod and the driving end of the motor are assembled, the first cooling channel is connected to the second cooling channel, and the liquid inlet of either the first cooling channel or the second cooling channel is connected to the cooling source, so that the coolant can flow through the first cooling channel and the second cooling channel, and finally be discharged from the liquid outlet of the other one. In this way, the coolant can take away the heat generated by the screw rod and the motor when they are working through heat exchange, and realize integrated cooling of the screw rod and the motor, effectively improving the heat dissipation efficiency.
