Description

Technical Field

[0001] The present application relates to the field of rotating mechanical equipment, and in particular to a turntable. Background Art

[0002] As a device that can rotate around a single axis, the turntable occupies an important position in the field of automation, especially in application scenarios that require precise control and positioning. Its design integrates knowledge from multiple disciplines such as automation science and mechanical engineering to adapt to diverse application needs. In recent years, with the rapid development of multifunctional composite CNC machine tools, automated turntables have become one of the key components for expanding machine tool functions, which is of great significance for improving production efficiency and processing accuracy. In addition, in order to meet higher-level needs, modern turntables are not limited to simple rotational movements, but also need to integrate a variety of additional functions, such as precise positioning, high-speed operation and high load capacity, which further promotes technological innovation and development in this field.

[0003] Most turntables currently on the market utilize internal motors, using complex transmission structures to precisely position and rotate physical workpieces. To ensure the stability and reliability of the motors, a series of auxiliary devices are often required, such as encoders for monitoring rotational speed and position, and sensors for real-time feedback on equipment operating status.

[0004] Existing turntable technology typically uses an internal motor and a series of transmission mechanisms to drive the turntable, achieving the desired rotational operation. These turntables are often also equipped with various sensing elements, such as sensors and encoders, to ensure accurate rotational position and stable operation. To ensure the effective operation of these sensing elements, measures must be taken to prevent the negative impact of electromagnetic interference from the drive system.

[0005] However, existing turntable designs often overlook the potential impact of electrical wiring layout, especially the fact that the electromagnetic effects generated by the connecting wires of drive components (such as motors) may interfere with other sensitive components (such as encoders and sensors), leading to unstable or even distorted signal transmission. These problems directly affect the overall performance and working stability of the turntable. Utility Model Content

[0006] In order to improve the stability of the turntable operation, the present application provides a turntable.

[0007] The present application provides a turntable adopting the following technical solution:

[0008] The transmission mechanism is connected with the transmission mechanism by the support frame, and the support frame is connected with the support frame by the support frame, and the support frame is connected with the support frame by the support frame.

[0009] By adopting the above technical solution, a wiring ring is added between the motor stator and the base of the turntable, and strong line channels and weak line channels are set on the wiring ring, which effectively avoids mutual interference between strong and weak current lines, improves the stability and reliability of encoder signal transmission, and further enhances the working performance and overall stability of the turntable.

[0010] Optionally, an air pipe joint is provided on the outer side wall of the chassis, and an air intake channel is provided on the inner side wall of the chassis in communication with the air pipe joint, and the air intake channel is used to transport cooling gas to the motor stator.

[0011] By adopting the above technical solution, when the stator drives the rotor to rotate, the stator generates heat. The air pipe joint provided on the outer wall of the chassis and the air inlet channel connected to the air pipe joint on the inner wall of the chassis enable the cooling gas to be effectively transported to the motor stator, thereby improving the heat dissipation effect of the motor stator, reducing the possibility of motor failure due to heat, and thus enhancing the stability and reliability of the turntable operation.

[0012] Optionally, a plurality of annular grooves are provided on the outer peripheral side wall of the motor stator facing the air inlet passage and parallel to the motor stator's own axis.

[0013] By adopting the above technical solution, several annular grooves opened parallel to the axial direction on the outer peripheral side wall of the motor stator facing the air inlet channel help to distribute the cooling gas more evenly around the motor stator, thereby effectively improving the heat dissipation efficiency of the motor stator and enhancing the stability of the turntable during operation.

[0014] Optionally, a plurality of pull rings are provided on the outer ring of the base.

[0015] By adopting the above technical solution, the multiple pull rings arranged on the outer ring of the base facilitate the handling and positioning operations of the turntable during installation and maintenance, thereby improving work efficiency and reducing the labor intensity of operators.

[0016] Optionally, a connecting portion for docking and installing other mechanical equipment is coaxially arranged on the workbench, and the connecting portion includes a coaxially arranged support ring and a connecting ring, the support ring is in the inner ring position, and is used to position and support the inner ring side wall of the connecting part of other mechanical equipment, the connecting ring is in the outer ring position, and a plurality of connecting screw holes are arranged on the circumference of the connecting ring, which is used to connect with other mechanical equipment through bolts.

[0017] By adopting the above technical solution, when connecting the turntable with other mechanical equipment, the connecting parts of the other equipment are first put on the abutment ring, and the connecting parts are docked with the connecting screw holes on the connecting ring, and bolts are used for connection and assembly. This can effectively improve the accuracy and stability of docking and installation with other mechanical equipment, ensure the reliability of the connection, and make the turntable perform better in the collaborative work of multiple devices.

[0018] Optionally, a guiding slope is coaxially provided on the top outer ring side wall of the support ring.

[0019] By adopting the above technical solution, the coaxial guide bevel on the top outer ring side wall of the support ring can effectively guide the rapid positioning and docking of other mechanical equipment, reduce the deviation generated during the installation process, and thus improve the overall assembly efficiency and accuracy.

[0020] Optionally, the support ring is formed by a number of support arc blocks with overlapping arc centers, and a guide rod is provided on the side wall of the bottom of each support arc block facing the connecting ring. The intersection point of the length direction of each guide rod coincides with the axis center of the connecting part, and a guide groove is provided on the connecting ring corresponding to each guide rod, and the guide groove corresponds to the guide rod one by one and is slidably fitted.

[0021] By adopting the above technical solution, when the inner diameter of the connecting member of other mechanical equipment is small, it is placed on a support ring formed by a plurality of support arc blocks with overlapping arc centers. As the guide inclined surface presses downward, the plurality of support arc blocks simultaneously contract toward the axis along the sliding direction of the guide rod until the support arc blocks enter the inner ring of the connecting member and contact the inner ring sidewall of the connecting member. The sliding fit between the support arc blocks and the guide rod and the connecting ring improves the adaptability of the turntable to the connecting member, thereby expanding the turntable's range of application.

[0022] Optionally, the inner arc side walls of several of the supporting arc blocks are provided with plug-in parts, and a metal spring sheet coated with an insulating coating is provided between each two adjacent plug-in parts.

The plug-in sections are plugged into the corresponding plug-in parts and plugged into and matched with the plug-in parts. The ends of the two plug-in sections located in the same plug-in part are arranged to abut against each other.

[0023] By adopting the above technical solution, when several supporting arc blocks shrink toward the axis together along the sliding direction of the guide rod, the ends of the two plug-in sections in the same plug-in section contact each other, and the deformation section undergoes elastic deformation, and always provides a clamping force for the several supporting arc blocks to press against the inner ring side wall of the connector. When the connectors of other mechanical equipment are removed, the supporting ring returns to its original state under the action of the metal spring sheet, so that the turntable can be installed with other mechanical equipment again, so that the turntable has good elasticity and stability during the installation process, and enhances the reliability and convenience when connecting with other mechanical equipment. At the same time, the insulating coating avoids electrical interference and ensures the stability of the turntable.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. A wiring loop is added between the motor stator and the base of the turntable, and strong and weak line channels are set on the wiring loop. This effectively avoids mutual interference between strong and weak current lines, improves the stability and reliability of encoder signal transmission, and further enhances the working performance and overall stability of the turntable;

The air pipe joint provided on the outer wall of the chassis and the air inlet channel connected to the air pipe joint on the inner wall of the chassis enable the cooling gas to be effectively delivered to the motor stator, thereby improving the heat dissipation effect of the motor stator and reducing the possibility of motor failure due to heat, thereby enhancing the stability and reliability of the turntable operation;

[0027] 3.

[0035] The following is combined with Figure 1-5 This application is described in further detail.

[0036] The embodiment of the present application discloses a turntable.

[0037] Example 1

[0038] Reference Figures 1 to 3 A turntable includes a chassis 1, a base 2, a rotating shaft 3, a motor rotor 4, a motor stator 5, an adapter ring 6, and a workbench 7. The outer ring of the base 2 is provided with multiple pull rings 21. One end of the rotating shaft 3 is coaxially connected to the base 2 via a bearing, and the other end of the rotating shaft 3 is fixedly connected to the workbench 7. The motor rotor 4 and the motor stator 5 are located between the base 2 and the workbench 7, and the motor stator 5 is coaxially mounted on the base 2. The motor rotor 4 is connected to the workbench 7 via the adapter ring 6. The interaction between the motor rotor 4 and the motor stator 5 can drive the rotating shaft 3 to drive the workbench 7 to rotate. A heat dissipation channel 8 is also provided in the chassis 1, and a connection portion 9 for docking and mounting other mechanical equipment is also coaxially mounted on the workbench 7.

[0039] Reference Figure 1The pull ring 21 is fixedly connected to the base 2 by bolt fasteners. This not only improves the convenience during transportation, but also avoids the need for additional transportation tools, making the installation process more efficient. The design of the pull ring 21 should ensure its sufficient strength and stability to avoid deformation or falling off during transportation. For example, each pull ring 21 can be made of round steel with a diameter of 10 mm and fixed to the base 2 by welding to provide sufficient tensile support. In addition, the position of the pull ring 21 should be evenly distributed on the outer ring of the entire base 2 to achieve uniform force.

[0040] Reference Figure 2 The heat dissipation channel 8 includes an air inlet channel 81 and an annular groove 82 that are interconnected. The air inlet channel 81 is provided on the inner sidewall of the chassis 1, and a tracheal connector 11 is fixedly mounted on the outer sidewall of the chassis 1. The tracheal connector 11 is interconnected with the air inlet channel 81. A plurality of annular grooves 82 are provided on the outer peripheral sidewall of the motor stator 5, facing the air inlet channel 81. A plurality of annular grooves 82 are provided parallel to the axial direction of the motor stator 5. Cooling gas can be introduced into the chassis 1 through the tracheal connector 11, then directed toward the motor stator 5 through the air inlet channel 81 within the chassis 1, and finally diffused through the annular grooves 82 on the motor stator 5, effectively cooling the motor stator 5. These annular grooves 82 are interconnected with the air inlet channel 81, and their openings face the outside of the motor stator 5 to facilitate the discharge of air.

[0041] Reference Figure 1 The connecting part 9 includes a coaxially arranged support ring 91 and a connecting ring 92. The support ring 91 is in the inner ring position and is used to position and support the inner ring side wall of the connection with other mechanical equipment. A guide slope is coaxially opened on the top outer ring side wall of the support ring 91. During the installation process, the guide slope can help the equipment quickly find the accurate position and improve the installation efficiency.

[0042] Reference Figure 1 The connecting ring 92 is located on the outer ring and is provided with a number of screw holes 921 around its circumference for bolting to other mechanical equipment. The screw holes are evenly distributed along the outer edge of the connecting ring 92 to ensure uniform force distribution, thus achieving a stable connection between other mechanical equipment and the turntable and improving positioning accuracy.

[0043] Reference Figure 2 and Figure 3In order to effectively separate the strong current and weak current signal lines and avoid electromagnetic interference, a wiring ring 51 with an annular structure is provided between the motor stator 5 and the base 2. The wiring ring 51 is coaxially fixed on the bottom wall of the motor stator 5, and a strong line channel 511 and a weak line channel 512 are connected and recessed on the wiring ring 51. The strong line channel 511 is used to install the connecting line connected to the motor stator 5, and the weak line channel 512 is used to install the connecting line connected to the encoder, and the wiring ring 51 has a wire entry hole 513 for the connecting wires to pass through corresponding to the strong line channel 511 and the weak line channel 512.

[0044] The implementation principle of a turntable in the present embodiment is as follows: by introducing a wiring loop 51 structure, it can effectively separate strong and weak current signal lines. The strong line channel 511 is used to accommodate the connection line between the external power supply and the motor stator 5, and the weak line channel 512 is used to accommodate the connection line between the external power supply and the encoder. This avoids electromagnetic interference, thereby improving the stability and reliability of the turntable operation and extending the turntable's service life. This design can ensure the stability of signal transmission from sensitive components such as the encoder, thereby improving the accuracy and efficiency of the turntable.

[0045] The provision of cooling channels effectively cools the motor stator 5, reducing the motor's operating temperature and improving its stability and reliability. Furthermore, the provision of pull rings 21 effectively enhances the convenience and safety of handling and installation, thereby improving the ease of use and efficiency of the entire turntable. Furthermore, the provision of connectors 9 enables a stable connection between other mechanical equipment and the turntable, enhancing positioning accuracy. The structural design of connectors 9 ensures precise installation and positioning of equipment, thereby improving the efficiency and reliability of the entire turntable.

[0046] Example 2

[0047] Reference Figure 4 and Figure 5 The difference between this embodiment and embodiment 1 is that the matching design between the support ring 91 and the connecting ring 92 adopts an arc center coincidence structure. The support ring 91 is surrounded by a number of support arc blocks 911 with coincident arc centers, and this embodiment takes four as an example. A guide rod 912 is integrally formed on the side wall of the bottom of each support arc block 911 facing the connecting ring 92. The intersection of the length direction of the guide rod 912 coincides with the axis of the connecting part 9. A guide groove 922 is provided on the connecting ring 92 corresponding to each guide rod 912, and the guide groove 922 corresponds to the guide rod 912 one by one and is slidably matched.

[0048] Reference Figure 4 and Figure 5In addition, the inner arc sidewalls of the several supporting arc blocks 911 with overlapping arc centers on the supporting ring 91 are all integrally formed with plug-in portions 9111. A metal spring 913 coated with an insulating coating is disposed between each two adjacent plug-in portions 9111. Each metal spring 913 includes a deformable section 9131 and plug-in sections 9132 located on either side of the deformable section 9131. The plug-in sections 9132 are inserted into the corresponding plug-in portion 9111 and engage with the plug-in portions 9111. The ends of the two plug-in sections 9132 located in the same plug-in portion 9111 are arranged to abut against each other.

[0049] The implementation principle of Example 2 is as follows: through the arc center overlap structure, when the inner diameter of the other mechanical equipment connecting part is small, it is placed on the support ring 91 formed by a plurality of support arc blocks 911 with overlapping arc centers. As the guide slope is pressed downward, the plurality of support arc blocks 911 are collectively contracted toward the axis along the sliding direction of the guide rod 912 until the support arc blocks 911 enter the inner ring of the connecting part and contact the inner ring side wall of the connecting part. At the same time, due to the mutual contact between the ends of the two plug-in sections 9132 in the same plug-in portion 9111, the deformation section 9131 undergoes elastic deformation, and constantly provides a clamping force for the plurality of support arc blocks 911 to press against the inner ring side wall of the connecting part.

[0050] When the connectors of other mechanical equipment are removed, the support ring 91 returns to its original state under the action of the metal spring 913, allowing the turntable to be installed with other mechanical equipment again. This not only improves the adaptability of the turntable, but also makes the turntable have good elasticity and stability during the installation process.

[0051] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
