Description

Technical Field

[0001] The invention relates to the technical field of conductive slip rings, in particular to a wear-resistant conductive slip ring suitable for high-speed rotating bodies. Background Art

[0002] Conductive slip ring is a general term for a series of conductive slip rings with a hole in the center. It can be used for 360-degree unlimited rotation of power, control and digital signal mixed transmission. It is commonly used in high-end industrial electrical equipment or precision electronic equipment with multi-function, high performance, high precision and multiple continuous rotation motion. It has low contact pressure, maintenance-free, no need for lubricating oil, low noise and low contact wear. It is usually used in wind power generation, military equipment, revolving doors and industrial robots.

[0003] When the conductive ring is in use, the inner slip ring and the rotating shaft are fixed and then rotate together. When conducting electricity, the transmission of current and signals is mainly achieved through the continuous sliding contact between the stationary carbon brush in the outer shell and the conductive ring that continuously rotates with the slip ring. Although the carbon brushes in the existing conductive rings have excellent wear resistance, during continuous operation, the carbon brushes and the conductive rings are always in a state of friction. After long-term use, the carbon brushes will still wear out. The gap between the worn carbon brushes and the conductive rings will lead to unstable current and signal transmission. The service life needs to be further improved.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. When the present invention is used, the highly wear-resistant conductive carbon brush is worn out after long-term use, and the spring provides thrust, and the damper ensures that it stably fits the conductive ring. At the same time, when the conductive carbon brush moves, the fifth connecting rod rotates and the ninth rotating seat moves in the slide rail, forming a supporting effect, so that the conductive carbon brush always fits the conductive ring tightly.

[0018] 2. When the present invention is used, the transmission line design is different from the three-input and three-output lines of the traditional conductive slip ring. The present conductive slip ring adopts a six-input and six-output line design, in which any three lines are used as common current and signal transmission lines. When a line fails, it is only necessary to remove the corresponding gear surface hook from the shell surface block. At this time, the tie rod connecting the adjacent gears shrinks, and the two gears rotate under the tension, and the two ends of the tie rod are constantly approaching. In this process, the gear drives the fourth connecting rod to rotate outward through the connecting shaft. Since the fourth connecting rod and the third connecting rod form a parallelogram structure, the third connecting rod will rotate outward synchronously, and then The connecting rods inside the shell are driven away from each other, so that the brush assembly of the faulty line is away from the conductive ring, and then the gears in another set of line adjustment components are rotated to make the hooks engage with the shell blocks, and the conductive carbon brushes of the corresponding brush assembly can slide in contact with the conductive ring to transmit current and signals. This design not only improves the service life of the conductive slip ring, but also does not need to be removed when a fault occurs. It can continue to work by simply adjusting the line. The function is novel and practical, which greatly improves the reliability and ease of use of the equipment, is conducive to its widespread promotion and use in the market, and brings users a more convenient and efficient use experience.

[0019] 3. When the present invention is used, it is easy to operate. It only needs to pass the rotating shaft of the power device through the inner hole of the rotating slip ring, and the device can be installed by pushing the extruded rubber plate and rotating the anti-slip ring. The anti-slip ring is raised by the threaded action, and the fourth rotating seat is squeezed to drive the second connecting rod to rotate, and then the first connecting rod is pushed to make the extruded rubber plate move vertically synchronously and tightly contact the rotating shaft. Compared with the traditional conductive slip ring fixing method with a large number of bolts, the installation efficiency is greatly improved. No complicated tools and cumbersome steps are required. The installation can be completed by pushing the device with one hand and rotating the anti-slip ring with the other hand, which saves time and labor costs and provides an efficient and convenient solution for the connection between the power device and the conductive slip ring.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figure 1-Figure 10As shown, the present invention provides a technical solution: a wear-resistant conductive slip ring suitable for a high-speed rotating body, comprising two connecting shells 31, the inner surface walls of the two connecting shells 31 are both installed with bearings 3, a slip ring assembly 1 is fixedly connected between the inner surface walls of the two bearings 3, three mounting mechanisms 2 are arranged inside the slip ring assembly 1, six interconnected line adjustment assemblies 4 are arranged between the slip ring assembly 1 and the outer surfaces of the two connecting shells 31, brush assemblies 5 are symmetrically arranged inside the line adjustment assemblies 4, and line assemblies 6 for power supply are arranged between the outsides of the six line adjustment assemblies 4, the slip ring assembly 1 comprises a rotating slip ring 101, six conductive rings 102 are equidistantly embedded on the outer surface of the rotating slip ring 101, six first connecting wires 103 are fixedly connected to the top of the rotating slip ring 101 near the edge, the six first connecting wires 103 are electrically connected to the six conductive rings 102 through internal lines, and the brush assembly 5 comprises a conductive carbon brush 50 1. The outer surface of the conductive carbon brush 501 is symmetrically fixedly connected with an eighth rotating seat 502 near the edge, and a fifth connecting rod 503 tilted outward is rotatably connected between the inner surface walls of the two eighth rotating seats 502. The outer surface of the fifth connecting rod 503 is rotatably connected with a ninth rotating seat 504 near the outer side, and the outer side of the ninth rotating seat 504 is slidably connected with a slide rail 505. The outer surface of the conductive carbon brush 501 is fixedly connected with a damper 507 near the middle, and the outer sleeve of the damper 507 is provided with a spring 506. The circuit assembly 6 includes a wiring board 601. The outer surface of the wiring board 601 is equidistantly connected with six external wirings 602 near the rear side, and the outer surfaces of both sides of the wiring board 601 are symmetrically and equidistantly connected with six internal wirings 603. Each external wiring 602 is electrically connected to two internal wirings 603 through the internal circuit of the wiring board 601, and the twelve internal wirings 603 are electrically connected to the twelve conductive carbon brushes 501 respectively.

[0033] In this embodiment, when in use, the rotating slip ring 101 will drive the conductive ring 102 to rotate synchronously with the rotating shaft of the power device. During this process, the conductive carbon brush 501 inside the housing 401 will pass through the opening 403 and slide in contact with the corresponding conductive ring 102, so that the stationary conductive carbon brush 501 and the rotating conductive ring 102 are always in an electrically connected state. At the same time, the external current and signal are input into the wiring board 601 through the external wire 602, and then transmitted to the conductive carbon brush 501 through the corresponding internal wire 603, and then output through the conductive ring 102 and the corresponding first connecting wire 103, thereby ensuring that various signals and currents are transmitted uninterruptedly while the device rotates, and has high wear resistance. When the conductive carbon brush 501 is worn out after long-term use, the spring 506 will generate an inward thrust on the conductive carbon brush 501, and the intervention of the damper 507 ensures that the conductive carbon brush 501 is stably fitted with the conductive ring 102. At the same time, when the conductive carbon brush 501 is moving, the two ends of the inclined fifth connecting rod 503 will respectively rotate with the eighth rotating seat 502 and the ninth rotating seat 504, and the ninth rotating seat 504 will move linearly in the slide rail 505, thereby constituting a supporting effect for the conductive carbon brush 501, so that the conductive carbon brush 501 will always be closely fitted with the conductive ring 102 even if it is worn out after long-term use, ensuring the stability when transmitting current and signals, and the service life is effectively improved.

[0034] Embodiment 2: Figure 1-Figure 10As shown, the line adjustment component 4 includes a shell 401, a built-in groove 402 is opened inside the shell 401, and an opening 403 is symmetrically opened on the inner surface wall of the shell 401. A gear 405 is symmetrically connected to the inner bottom of the shell 401 near the front side, and the two gears 405 are meshed with each other. The inner surface walls on both sides of the built-in groove 402 are symmetrically connected to the fifth rotating seat 409 near the gear 405. A connecting shaft 410 is fixedly connected to the top center of the gear 405. The inner surface of the fifth rotating seat 409 is A third connecting rod 411 extending outward is rotatably connected between the walls, a fourth connecting rod 412 extending outward is fixedly connected to the outer surface of the connecting shaft 410, the third connecting rod 411 and the fourth connecting rod 412 are in a parallel arc state and the lengths of the third connecting rod 411 and the fourth connecting rod 412 are the same, the outer end of the third connecting rod 411 is rotatably connected to a sixth rotating seat 413, the outer end of the fourth connecting rod 412 is rotatably connected to a seventh rotating seat 414, and the outer surfaces of the sixth rotating seat 413 and the seventh rotating seat 414 are close to the outer side. The connecting rod 415 is fixedly connected to the position of the connecting rod 415, and the connecting rod 415 extends to the rear side. The outer surface of the inner wire 603 penetrates from the outside of the housing 401 and extends into the built-in groove 402. The two ends of the spring 506 are respectively fixedly connected to the outer surfaces of the conductive carbon brush 501 and the opposite sides of the connecting rod 415. The conductive carbon brush 501 corresponds to the position of the opening 403 and cooperates with the conductive ring 102. One end of the damper 507 is fixedly connected to the inner outer surface of the connecting rod 415. The slide rail 505 is fixedly installed on the connecting rod 4 15, the outer surface of the gear 405 extends to the outside of the shell 401 near the front side, the tops of two adjacent gears 405 are fixedly installed with screws 407 near the front side, and a tie rod 408 is sleeved between the outer surfaces of the two adjacent screws 407. The outer surface of the shell 401 is fixedly connected with a block 404 near the right side, and the top of the gear 405 on the right side is fixedly installed with a hook 406 extending to the right, and the end of the hook 406 cooperates with the block 404.

[0035] In this embodiment, most of the conventional conductive slip ring circuits are three-input and three-output, while the conductive slip ring circuit of this embodiment is six-input and six-output, wherein any three lines are commonly used transmission lines for current and signals. When a line fails, the end of the hook 406 on the surface of the corresponding gear 405 is removed from the block 404 on the surface of the housing 401. At this time, the gear 405 loses its fixation, and the tie rod 408 connected by the screw 407 near the front side of the adjacent gear 405 will shrink. At this time, the two gears 405 will rotate after being subjected to tension, and the two ends of the tie rod 408 will keep approaching each other during the rotation. In this process, the gear 405 will drive the fourth connecting rod 412 to rotate outward through the connecting shaft 410, and since the fourth connecting rod 412 and the third connecting rod 411 are in a quasi-parallel arc state and have the same length, thus forming a parallelogram, the fourth connecting rod 41 When the third connecting rod 411 rotates outward, it will rotate outward synchronously under the action of the sixth rotating seat 413 and the fifth rotating seat 409, thereby driving the two connecting rods 415 inside the housing 401 to move away from each other. At this time, the brush assembly 5 on the surface of the connecting rod 415 will move away from the conductive ring 102, and then the gear 405 in the other group of line adjustment components 4 will be rotated, and the end of the hook 406 on its surface will be engaged with the block 404 on the surface of the housing 401. At this time, the conductive carbon brush 501 in the corresponding brush assembly 5 can slide in contact with the corresponding conductive ring 102 and transmit current and signals. The design of the six transmission lines of the conductive slip ring has a qualitative improvement in the service life, and when a fault occurs during use, it only needs to simply adjust the line to continue working without dismantling. The design is novel and practical, which is conducive to long-term promotion and use.

[0036] Embodiment 3: Figure 1-Figure 10As shown, a threaded sleeve 104 is threadedly connected to the inner surface wall of the rotating slip ring 101 near the bottom, and a plurality of balls 106 are equidistantly rollingly connected to the top of the threaded sleeve 104. An anti-slip ring 105 extending outward is fixedly connected to the bottom of the threaded sleeve 104 near the edge. The outer diameter of the anti-slip ring 105 is consistent with the outer diameter of the rotating slip ring 101. Three mounting mechanisms 2 are equidistantly installed at the inner wall of the conductive ring 102 near the top. The mounting mechanism 2 includes an extruded rubber plate 201. The outer surface of the extruded rubber plate 201 is symmetrically fixedly connected to the first rotating seat 202 near the top and the bottom. The inner surface walls of the two first rotating seats 202 are both rotatably connected to the outer side. The first connecting rod 203 extends upward, and the outer surfaces of the two first connecting rods 203 are rotatably connected to the second rotating seat 204 near the top, and the outer surface of the second rotating seat 204 is fixedly connected to the inner surface wall of the conductive ring 102. The bottom of the first connecting rod 203 located below is fixedly connected to the third rotating seat 205, and the second connecting rod 206 extending downward and outward is rotatably connected between the inner surfaces of the third rotating seat 205. The bottom end of the second connecting rod 206 is rotatably connected to the fourth rotating seat 207, and the fourth rotating seat 207 is slidably connected to the inner surface wall of the conductive ring 102, and the bottom of the fourth rotating seat 207 is in conflict with the outer surface of the ball 106.

[0037] In this embodiment, when in use, the rotating shaft of the power device is passed through the inner hole of the rotating slip ring 101, and then one hand pushes the device so that one of the extruding rubber plates 201 is against the surface of the rotating shaft, and then the other hand pinches the anti-slip ring 105 and rotates it. Under the action of the thread, the anti-slip ring 105 will slowly rise upward inside the rotating slip ring 101 when it rotates, and its top will squeeze the three fourth rotating seats 207 upward to move upward on the inner wall of the rotating slip ring 101. When the fourth rotating seat 207 moves upward, the bottom end of the second connecting rod 206 will rotate with the fourth rotating seat 207 and the top end will rotate with the third rotating seat The movable seat 205 rotates, and during this process, the top end of the second connecting rod 206 will generate an oblique thrust on the first connecting rod 203 below, and the two first connecting rods 203 are in a similar parallel state, and the four rotation points form a parallelogram, so the inner ends of the two first connecting rods 203 will be lifted up synchronously, and all the extruded rubber plates 201 are always in a vertical state and move synchronously during the process. When all the extruded rubber plates 201 and the rotating shaft of the power device are tightly in contact, the installation of the device can be completed. This installation method is easy to operate and effectively improves the installation efficiency compared to the traditional method of fixing the conductive slip ring with a large number of bolts.

[0038] The effect and working principle of the whole mechanism are as follows: when in use, the rotating shaft of the power device is passed through the inner hole of the rotating slip ring 101, and then one hand pushes the device so that one of the extruding rubber plates 201 is against the surface of the rotating shaft, and then the other hand pinches the anti-slip ring 105 and rotates it. Under the action of the thread, the anti-slip ring 105 will slowly rise upward inside the rotating slip ring 101 when it rotates, and its top will squeeze the three fourth rotating seats 207 upward to move upward on the inner wall of the rotating slip ring 101. When the fourth rotating seat 207 moves upward, the bottom end of the second connecting rod 206 will rotate with the fourth rotating seat 207 and the top end The second connecting rod 206 will rotate with the third rotating seat 205. During this process, the top end of the second connecting rod 206 will generate an oblique thrust to the first connecting rod 203 below. The two first connecting rods 203 are in a similar parallel state, and the four rotating points form a parallelogram. Therefore, the inner ends of the two first connecting rods 203 will be lifted up synchronously, and all the extruded rubber plates 201 are always in a vertical state and move synchronously during the process. When all the extruded rubber plates 201 and the rotating shaft of the power device are tightly in contact, the installation of the device can be completed. This installation method is easy to operate and effectively improves the installation efficiency compared to the traditional method of fixing the conductive slip ring with a large number of bolts.

[0039] During operation, the rotating slip ring 101 will drive the conductive ring 102 to rotate synchronously with the rotating shaft of the power device. During this process, the conductive carbon brush 501 inside the housing 401 will pass through the opening 403 and slide in contact with the corresponding conductive ring 102, so that the stationary conductive carbon brush 501 and the rotating conductive ring 102 are always in an electrically connected state. At the same time, the external current and signal are input into the wiring board 601 through the external wire 602, and then transmitted to the conductive carbon brush 501 through the corresponding internal wire 603, and then output through the conductive ring 102 and the corresponding first connecting wire 103, thereby ensuring that various signals and currents are transmitted uninterruptedly while the device rotates, and having high wear resistance. When the conductive carbon brush 501 is worn out after long-term use, the spring 506 will generate an inward thrust on the conductive carbon brush 501, and the intervention of the damper 507 ensures that the conductive carbon brush 501 is stably fitted with the conductive ring 102. At the same time, during the activity of the conductive carbon brush 501, the two ends of the inclined fifth connecting rod 503 will rotate with the eighth rotating seat 502 and the ninth rotating seat 504 respectively, and the ninth rotating seat 504 will move linearly in the slide rail 505, thereby forming a supporting effect for the conductive carbon brush 501, so that the conductive carbon brush 501 will always be closely fitted with the conductive ring 102 even if it is worn out after long-term use, ensuring the stability of transmitting current and signals, and the service life is effectively improved.

[0040] In addition, most of the conventional conductive slip ring circuits have three inputs and three outputs, while the conductive slip ring circuit of the present invention has six inputs and six outputs, wherein any three of the circuits are commonly used transmission lines for current and signals. When a certain circuit fails, the end of the hook 406 on the surface of the corresponding gear 405 is removed from the block 404 on the surface of the housing 401. At this time, the gear 405 loses its fixation, and the tie rod 408 connected by the screw 407 near the front side of the adjacent gear 405 will shrink. At this time, the two gears 405 will rotate after being subjected to tension, and the two ends of the tie rod 408 will keep approaching each other during the rotation. In this process, the gear 405 will drive the fourth connecting rod 412 to rotate outward through the connecting shaft 410, and since the fourth connecting rod 412 and the third connecting rod 411 are in a quasi-parallel arc state and have the same length, thus forming a parallelogram, the fourth connecting rod 412 is rotated to the outside. When the outer side rotates, the third connecting rod 411 will rotate outward synchronously under the action of the sixth rotating seat 413 and the fifth rotating seat 409, thereby driving the two connecting rods 415 inside the shell 401 to move away from each other. At this time, the brush assembly 5 on the surface of the connecting rod 415 will move away from the conductive ring 102, and then the gear 405 in the other group of line adjustment components 4 will be rotated, and the end of the hook 406 on its surface will be engaged with the block 404 on the surface of the shell 401. At this time, the conductive carbon brush 501 in the corresponding brush assembly 5 can slide in contact with the corresponding conductive ring 102 and transmit current and signals. The design of the six transmission lines of the conductive slip ring has a qualitative improvement in the service life, and when a fault occurs during use, it only needs to simply adjust the line to continue working without dismantling. The design is novel and practical, which is conducive to long-term promotion and use.
