Description

Technical Field

[0001] This utility model relates to the field of servo drive related products, specifically a servo drive with a pressure-resistant structure. Background Technology

[0002] A servo drive, also known as a servo controller or servo amplifier, is a controller used to control servo motors. Its function is similar to that of a frequency converter for a regular AC motor. It is part of a servo system and is primarily used in high-precision positioning systems. Generally, it controls the servo motor through position, speed, and torque to achieve high-precision positioning of the transmission system. Currently, it represents a high-end product in transmission technology.

[0003] To enhance the protection capabilities of servo drives during use, a pressure-resistant shell is typically added to the surface. However, traditional pressure-resistant shells rely on the hardness of the shell material itself to increase the pressure resistance of the servo drive, which is affected by the material and is therefore insufficient. Utility Model Content

[0004] The purpose of this invention is to provide a servo driver with a pressure-resistant structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a servo driver with a pressure-resistant structure, comprising a housing, a servo driver body, and a housing cover. The servo driver body is installed inside the housing, and the housing cover is installed at the end of the housing. A pressure-resistant component is provided on the outer side of the housing. The pressure-resistant component includes two opposing buffer shells. Two symmetrically arranged support blocks are fixedly connected to the inner walls of both sides of the buffer shells. A swing plate is rotatably connected to both ends of the two support blocks. A slider is rotatably connected to one end of each swing plate. A [missing information - likely a component name] is provided on one side of each support block. The traction plate has a groove corresponding to the slider. A sliding rod is fixedly connected in the groove. The slider is slidably sleeved on the sliding rod. A first elastic element is sleeved on the sliding rod. The two ends of the first elastic element are fixedly connected to the inner wall of the groove and the slider, respectively. A connecting block is fixedly connected to one side of the traction plate. The housing has a slot corresponding to the position of the connecting block. A bearing rod is fixedly connected in the slot. The connecting block is slidably sleeved on the bearing rod. A second elastic element is sleeved on the bearing rod. The two ends of the second elastic element are fixedly connected to the connecting block and the inner wall of the slot, respectively.

[0006] Preferably, both the first elastic element and the second elastic element are springs.

[0007] Preferably, both buffer shells are concave in shape and are secured to the outside of the housing.

[0008] Preferably, a rubber plate is fixedly connected to one inner wall of the buffer shell.

[0009] Preferably, the four corners of the cover are fixed to the housing by locking screws, and the cover has a shaft hole in the middle.

[0010] Preferably, the cover is provided with multiple heat dissipation grooves.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The servo drive with a pressure-resistant structure connects the buffer shell to the support rod on the main body of the servo drive via a connecting block. When the buffer shell is subjected to force, it will push the connecting block to slide on the support rod and squeeze the second elastic element, thereby achieving buffering by utilizing the rebound force of the second elastic element.

[0013] The servo driver with a pressure-resistant structure deforms the buffer shell when the outer wall of the buffer shell is subjected to force. At this time, the support block moves, which causes the swing plate to push the slider to slide on the slide rod and then squeeze the second elastic element. The buffer is achieved by the rebound force of the second elastic element.

[0014] This servo drive with a pressure-resistant structure increases its pressure resistance by setting an external buffer component, so that when it is subjected to impact or external pressure, it can disperse the pressure in time to achieve the purpose of pressure resistance.

The servo driver body 2 is installed inside the housing 1, and the cover 3 is installed at the end of the housing 1. A pressure-resistant component 4 is provided on the outside of the housing 1. The pressure-resistant component 4 includes two buffer shells 5 arranged opposite each other. Two support blocks 6 are fixedly connected to the inner walls of both sides of the buffer shells 5, arranged symmetrically. Swing plates 7 are rotatably connected to both ends of the two support blocks 6. A slider 8 is rotatably connected to one end of the swing plate 7. A traction plate 9 is provided on one side of the support block 6. The traction plate 9 has a groove corresponding to the slider 8. A slide rod 10 is fixedly connected in the groove. The slider 8 is slidably sleeved on the slide rod 10. A first elastic element 11 is sleeved on the slide rod 10. The two ends of the first elastic element 11 are fixedly connected to the inner wall of the groove and the slider 8, respectively. The traction plate 9...

The two ends of the second elastic element 14 are fixedly connected to the connecting block 12 and the inner wall of the slot, respectively. Specifically, the connecting block 12 connects the buffer housing 5 to the bearing rod 13 on the servo drive body 2. When the buffer housing 5 is subjected to force, it will push the connecting block 12 to slide on the bearing rod 13 and squeeze the second elastic element 14. The rebound force of the second elastic element 14 is used to achieve buffering. When the outer wall of the buffer housing 5 is subjected to force, the buffer housing 5 deforms.

[0024] In this embodiment, both the first elastic element 11 and the second elastic element 14 are springs, which have high availability; both buffer shells 5 are concave structures and are snapped onto the outside of the shell 1; a rubber plate 15 is fixedly connected to one inner wall of the buffer shell 5 to increase the buffering force between it and the outer wall of the shell 1; the four corners of the shell cover 3 are fixed to the shell 1 by locking screws 16, and the shell cover 3 has a shaft hole in the middle; the shell cover 3 has multiple heat dissipation grooves 17 to dissipate heat from the inside of the shell 1.

[0025] Working principle: First, the connecting block 12 connects the buffer shell 5 to the bearing rod 13 on the servo drive body 2. When the buffer shell 5 is subjected to force, it pushes the connecting block 12 to slide on the bearing rod 13 and squeeze the second elastic element 14. The rebound force of the second elastic element 14 is used to achieve buffering. When the outer wall of the buffer shell 5 is subjected to force, the buffer shell 5 deforms. At this time, the support block 6 moves, which causes the swing plate 7 to push the slider 8 to slide on the slide rod 10 and squeeze the second elastic element 14. The rebound force of the second elastic element 14 is used to achieve buffering.
