Description

Technical Field

[0001] The utility model relates to the technical field of motor casings, in particular to an asynchronous servo motor casing structure. Background Art

[0002] A servo motor is an engine that controls the operation of mechanical components in a servo system. It is an auxiliary motor indirect speed change device. The servo motor can control speed and position accuracy, and can convert voltage signals into torque and speed to drive the controlled object. Servo motors include synchronous servo motors and asynchronous servo motors. Asynchronous servo motors are lower in cost than synchronous servo motors. At the same time, if the asynchronous servo motor is placed directly in a bare metal style during operation, it is susceptible to external damage. Therefore, we need a casing protection structure to protect the asynchronous servo motor, thereby extending the service life of the device.

[0003] Patent document CN212660053U discloses that "the utility model discloses a servo motor housing structure, including: a shell, a heat sink, an oil cooling mechanism and a shock-absorbing base mechanism; wherein: the shell includes: an inner wall layer, an intermediate layer and an outer wall layer; the intermediate layer is filled between the inner wall layer and the outer wall layer; the heat sink is arranged at the top of the outer wall layer; there are two oil cooling mechanisms, and the two oil cooling mechanisms are respectively arranged on the left wall and the right wall of the outer wall layer; the shock-absorbing base mechanism is arranged at the bottom end of the outer wall layer. In the servo motor housing structure of the utility model, the shell is designed as a three-layer structure with a heat dissipation filler, which increases the thermal conductivity of the shell and effectively improves the heat dissipation efficiency of the servo motor; heat sinks and oil cooling mechanisms are arranged on the outer wall layer of the shell, which on the one hand play a heat dissipation role and on the other hand increase the stability of the overall connection of the shell structure; a shock-absorbing base mechanism is also provided to increase the shock absorption effect of the servo motor and effectively extend the service life of the servo motor."

[0004] However, although the above device can achieve vibration reduction and heat dissipation of the servo motor when in use, since the servo motor generates heat when working, the floating impurities in the air will be attracted by the heat, which will cause the fixed impurities in the outside air to continuously approach or be adsorbed to the surface of the device or the inside of the vent, which may affect the use of the motor and cause pollution and blockage of the vent. Therefore, the device still has certain shortcomings and needs further improvement. Utility Model Content

[0026] Example 2:

[0027] See also Figure 3 、 Figure 4 and Figure 5 , including a first buffer groove 13 opened inside the base 1, the first buffer groove 13 is convenient for the asynchronous servo motor to have sufficient buffer space when vibrating, and it is also convenient for the first spring shock absorber 14 to be installed inside. The first buffer groove 13 is fixedly connected to the inside of the first spring shock absorber 14. As an existing technology, the first spring shock absorber 14 can buffer the asynchronous servo motor, thereby reducing vibration.

[0028] As an optional technical solution, the top of the first buffer groove 13 is fixedly connected to a first support seat 15, which facilitates the connection between the first connecting block 16 and the first spring shock absorber 14. The top of the first support seat 15 is fixedly connected to the first connecting block 16, which enables the first spring shock absorber 14 to be connected to the bottom support 17 device.

[0029] As an optional technical solution, the top of the first connecting block 16 is fixedly connected to a bottom support 17, which is used to wrap the lower half of the asynchronous servo motor. A first ventilation groove 18 is provided on the surface of the bottom support 17, which facilitates heat dissipation of the lower half of the asynchronous servo motor.

[0030] As an optional technical solution, a second buffer groove 19 is opened inside the top cover 2. The second buffer groove 19 provides sufficient buffer space for the asynchronous servo motor when it vibrates, and also facilitates the installation of the second spring shock absorber 20 inside. The second spring shock absorber 20 is fixedly connected to the inside of the second buffer groove 19. As an existing technology, the second spring shock absorber 20 can buffer the asynchronous servo motor, thereby reducing vibration.

[0031] The top of the second spring shock absorber 20 is fixedly connected to a second support seat 21, which facilitates the connection between the second connecting block 22 and the second spring shock absorber 20. The top of the second support seat 21 is fixedly connected to a second connecting block 22, which enables the second spring shock absorber 20 to be connected to the top support 23 device.

[0033] Working principle: when using the device to protect the asynchronous servo motor housing, first place the asynchronous servo motor on top of the bottom support 17, then pick up the top cover 2, so that the splicing block 11 under the top cover 2 is inserted into the inside of the splicing groove 8, and then screw the limit bolt 9, so that the limit bolt 9 can pass through the inside of the threaded groove 12, and then the top cover 2 and the base 1 form a whole, so that the bottom support 17 and the top support 23 can fix the asynchronous servo motor, and when the asynchronous servo motor is working, the hot air generated can pass through the first ventilation groove 18 and the second ventilation groove 12. The two ventilation grooves 24 enter the interior of the first buffer groove 13 and the second buffer groove 19, and then the hot air will be dissipated outward through the first vent 3 and the second vent 5, and the first baffle 4 and the second baffle 6 can block external air impurities from entering the interior of the device. At the same time, if the asynchronous servo motor vibrates greatly when working, the bottom support 17 and the top support 23 will pressurize the first spring shock absorber 14 and the second spring shock absorber 20 downward. At the same time, the first spring shock absorber 14 and the second spring shock absorber 20 can minimize the shaking and instability of the device through the reaction force.
