Description

Technical Field

[0001] The utility model relates to the technical field of servo drivers, in particular to a servo driver installation and positioning device. Background Art

[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] Servo drives can be widely used in industrial robots, CNC machine tools, automated production lines, textile machinery and other fields. In order to more accurately control the movement of the machine, the servo drive's connection line cannot be too long, so the servo drive is usually set inside the machine and connected to the machine's support frame or housing. However, the machine will produce vibrations and other factors during operation. Long-term vibrations will loosen the servo drive's connection line, thereby affecting the accuracy of the servo drive. Therefore, the servo drive needs to be regularly inspected to ensure its normal movement.

[0004] For moving machinery such as machine tools, one device requires multiple servo drives, which work together to achieve normal operation of the equipment. However, when the servo drives are connected to the machinery, multiple servo drives are usually connected to the machinery as a whole, which causes cumbersome maintenance and replacement. Therefore, how to connect multiple servo drives to the machinery in an orderly manner to facilitate regular maintenance of the servo drives is a problem to be solved. How to reduce the impact of vibration on the servo drive so that the servo drive can operate normally is also a problem to be solved. Utility Model Content

[0020] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.

[0021] The utility model is a servo drive installation and positioning device, the main structure includes a support device 1 and a shock absorbing device 2, the support device 1 and the shock absorbing device 2 are connected to the servo drive, and play a role in supporting, shock absorbing and positioning the servo drive. The servo drive can be stably connected to the machine, reduce the impact of mechanical vibration on it, and play a role in positioning the servo drive. The shock absorbing device 2 is arranged on the back side of the terminal on the servo drive, so that the servo drive can be normally connected to the machine on the line.

[0022] The shock absorbing device 2 includes a connector 3 and a shock absorbing member 4. The shock absorbing member 4 is connected to the mechanical parts so that the servo drive is indirectly connected to the mechanical parts. One end of the connector 3 is connected to the shock absorbing member 4, and the other end is connected to the servo drive, thereby fixing the servo drive. In order to meet the connection between multiple servo drives, the length of the connector 3 can be selected according to the number of servo motors to be connected, so that the connector 3 can connect the servo drive, and the central part of the connector 3 is provided with multiple connecting rods 5, and the number of connecting rods 5 corresponds to the number of springs 6 and columns 7 on the shock absorbing member 4 (detailed below). A spring 6 is provided in the middle of the shock absorbing member 4, and columns 7 are provided on both sides of the spring 6. The spring 6 and the column 7 on the shock absorbing member 4 are connected to the connecting rod 5 (continued above), and the spring 6 and the connecting rod 5 are fixedly connected, and the column 7 and the connecting rod 5 are slidably connected, that is, when vibration occurs, the spring 6 contracts or extends so that the column 7 and the connecting rod 5 can slide relative to each other, thereby playing a shock absorbing role. The two sides of the spring 6 are provided with columns 7 connected to the connecting rod 5 to reduce the occurrence of deviation during vibration, so that the moving direction of the servo driver is fixed.

[0023] The support device 1 includes a base plate 8 and a pad 9. The top of the base plate 8 contacts the servo drive, and the bottom of the base plate 8 is connected to the pad 9. The number of pads 9 is set according to the different heights of the servo drives set by different devices and the ground. A buffer limiter 10 is provided on the top of the base plate 8. The buffer limiter 10 contacts the side of the servo drive, thereby reducing the interference between two adjacent servo drives, that is, when a servo drive is repaired and replaced, the impact on the adjacent servo drive is reduced. The outside of the buffer limiter 10 is provided with a rubber shell, which plays a shock-absorbing role in daily use. A plurality of chutes 11 are also provided on the top of the base plate 8.

Here, a slider is preferably used so that the chutes 11 can better limit it. The sliding member 12 is fixedly connected to the bottom of the servo drive, so that when the mechanical vibration is too large, that is, the shock absorbing device 2 cannot fully absorb the vibration, it will drive the servo drive to move along the slide groove 11, thereby achieving the shock absorbing effect, so that the servo drive can be better positioned at this position, reducing the looseness of the terminal circuit of the servo drive and other problems.

[0024] Detailed instructions for use:

[0025] First, connect the bottom plate 8 and multiple pads 9 to the ground, then connect the servo drive to the corresponding position of the bottom plate 8, and then connect the shock absorber 2 to the multiple servo drives, and connect the other end of the shock absorber 2 to the skeleton, shell, etc. of the machine, so that the servo drive is indirectly connected to the machine. When the servo drive is too far from the ground, the bottom plate 8 and the pad 9 can be connected to the shell of the frame, thereby providing a support for the servo drive.

[0026] In summary, the device can reduce the impact of mechanical vibration on the servo drive, so that the servo drive can be stably installed and positioned. The device increases the service life of the connection end of the servo drive by elastic shock absorption, sliding, etc., and reduces the frequency of maintenance and inspection. The device is provided with a buffer limiter 10 between two adjacent servo drives to separate them, thereby reducing the impact of one servo drive on the adjacent servo drive when repairing one servo drive.
