Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a direct-drive planer-saw dual-purpose motor. Background Art

[0002] Direct drive planer saw motor is a motor with specific functions, which combines the two functions of planing and sawing. It is usually used in woodworking machinery or other occasions that require efficient cutting and processing. This motor has a compact design and powerful power, which can meet a variety of processing needs.

[0003] The direct-drive planer-saw motors currently on the market generate a lot of heat during operation. Although a heat dissipation mechanism is provided inside, the heat dissipation efficiency of the heat dissipation mechanism is often too poor, which causes the heat to not be dissipated in time, causing the motor temperature to rise, thereby affecting the performance and life of the motor. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a direct-drive planing and sawing dual-purpose motor.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A direct-drive planer-saw dual-purpose motor comprises a shell, a cavity is opened inside the shell, a bearing is arranged at the bottom of the cavity, a transmission shaft is inserted in the bearing, a rotor assembly is sleeved and installed on the transmission shaft, and the transmission shaft extends from the top of the shell; heat dissipation rings are installed on the upper and lower sides of the rotor assembly, a stator assembly is adapted to be arranged on the inner wall of the shell corresponding to the rotor assembly, and guide blocks are installed on the upper and lower sides of the stator assembly.

[0007] In addition, a preferred structure is that the heat dissipation ring is fixedly mounted on the upper and lower sides of the rotor assembly, and a plurality of heat dissipation fins are arranged on the outer side of the heat dissipation ring.

[0008] In addition, a preferred structure is that plug-in blocks are provided on both the upper and lower sides of the stator assembly, and slots are provided on the guide block corresponding to the plug-in blocks, and the plug-in blocks are adapted to the slots.

[0009] In addition, a preferred structure is that the guide block and the heat dissipation ring are at the same horizontal height, and a guide slope is provided on the guide block corresponding to the heat dissipation ring.

[0010] In addition, a preferred structure is that the shell is provided with two rows of “ring-shaped” heat dissipation holes, and the heat dissipation holes are all located at the air outlet of the guide block.

[0011] In addition, a preferred structure is that an “annular” baffle is installed on the inner wall of the shell, and the baffle is located on a side of the heat dissipation hole away from the guide block.

[0012] The beneficial effects of the utility model are as follows: the transmission shaft can be driven to rotate by the arrangement of the rotor assembly and the stator assembly, and the airflow in the shell can be guided out through the heat dissipation holes by the coordinated arrangement of the heat dissipation ring and the guide block, thereby achieving heat dissipation and cooling inside the shell, with high heat dissipation efficiency, which can ensure the normal use of the device.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-5 A direct-drive planer-saw dual-purpose motor comprises a shell 1, a cavity is formed inside the shell 1, a bearing 2 is arranged at the bottom of the cavity, a transmission shaft 21 is inserted in the bearing 2, a rotor assembly 3 is sleeved and mounted on the transmission shaft 21, and the transmission shaft 21 extends from the top of the shell 1; heat dissipation rings 4 are installed on the upper and lower sides of the rotor assembly 3, a stator assembly 5 is adapted to be arranged on the inner wall of the shell 1 corresponding to the rotor assembly 3, and guide blocks 6 are installed on the upper and lower sides of the stator assembly 5.

[0021] The heat dissipation ring 4 is fixedly mounted on the upper and lower sides of the rotor assembly 3, and a plurality of heat dissipation fins 41 are arranged on the outer side of the heat dissipation ring 4. The heat dissipation fins 41 can be driven to rotate by the synchronous rotation between the heat dissipation ring 4 and the rotor assembly 3, so that the air can flow through the heat dissipation fins 41, thereby rotating.

[0022] The upper and lower sides of the stator assembly 5 are both provided with plug blocks 51, and the guide block 6 is provided with slots 61 corresponding to the plug blocks 51, and the plug blocks 51 are adapted to the slots 61. Through the arrangement of the plug blocks 51 and the slots 61, the guide block 6 can be installed on the upper and lower sides of the stator assembly 5, and when installing the guide block 6, glue needs to be poured into the slots 61 to improve the stability of the guide block 6 after installation.

[0023] The guide block 6 and the heat dissipation ring 4 are at the same level, and a guide slope 62 is provided on the guide block 6 corresponding to the heat dissipation ring 4. The housing 1 is provided with two rows of "ring-shaped" heat dissipation holes 11, and the heat dissipation holes 11 are all located at the air outlet of the guide block 6. The heat dissipation ring 4 drives the air to flow, and then the flowing air flows out of the heat dissipation holes 11 through the guide slope 62.

[0024] Among them, a "ring-shaped" baffle plate 7 is installed on the inner wall of the housing 1, and the baffle plates 7 are all located on the side of the heat dissipation hole 11 away from the guide block 6. Through the setting of the baffle plate 7, the air guided on the guide slope 62 can be prevented from flowing to other places when it does not flow out of the heat dissipation hole 11, thereby preventing air turbulence in the housing 1.

[0025] In this embodiment, a cavity is provided inside the housing 1, a bearing 2 is provided at the bottom of the cavity, a transmission shaft 21 is inserted into the bearing 2, a rotor assembly 3 is sleeved and installed on the transmission shaft 21, and the transmission shaft 21 extends from the top of the housing 1. Heat dissipation rings 4 are installed on the upper and lower sides of the rotor assembly 3, a stator assembly 5 is adapted and provided on the inner wall of the housing 1 corresponding to the rotor assembly 3, and guide blocks 6 are installed on the upper and lower sides of the stator assembly 5. The heat dissipation ring 4 can drive the air in the housing 1 to flow, thereby achieving efficient heat dissipation of the device. It is worth noting that the transmission shaft 21 can be driven to rotate by the arrangement of the rotor assembly 3 and the stator assembly 5. The specific structures and working methods of the rotor assembly 3 and the stator assembly 5 are all prior art, and do not belong to the main technical problems solved in this technical solution, so they are not elaborated in this utility model.

[0026] Furthermore, when the rotor assembly 3 rotates, the heat dissipation ring 4 can be driven to rotate, so that the heat dissipation fins 41 on the heat dissipation ring 4 can drive the air flow, and the air in the housing 1 flows to the guide block 6 through the rotation of the heat dissipation fins 41, and then flows to the heat dissipation hole 11 through the guide slope 62, and finally flows out from the heat dissipation hole 11, so as to achieve heat dissipation in the housing 1. And through the setting of the baffle plate 7, the airflow that does not flow out of the heat dissipation hole 11 can be blocked to prevent the airflow in the housing 1 from being too large and forming turbulence. And the bottom of the housing 1 is provided with air holes to ensure the pressure balance in the housing 1.

[0027] In the utility model, the transmission shaft 21 can be driven to rotate by the arrangement of the rotor assembly 3 and the stator assembly 5, and the airflow in the shell 1 can be guided out through the heat dissipation holes 11 by the coordinated arrangement of the heat dissipation ring 4 and the guide block 6, thereby achieving heat dissipation and cooling inside the shell 1, with high heat dissipation efficiency, which can ensure the normal use of the device.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
