Description

Technical Field

[0001] The utility model belongs to the technical field of slip rings, and in particular relates to a novel rotor slip ring. Background Art

[0002] Slip rings are also called conductive rings, slip rings, collector rings, and collector rings. They can be used in any electromechanical system that requires continuous rotation and needs to transmit power and signals from a fixed position to a rotating position. Slip rings can improve system performance, simplify system structure, and avoid twisting of wires during rotation. Collector ring series synchronous motors and asynchronous motors use collector rings.

[0003] The existing slip ring is directly in contact with the internal rotor after conducting electricity through the sliding block. The rotor constantly rubs against the sliding block. Under long-term friction, the sliding block is prone to wear. After excessive wear, the contact effect between the sliding block and the rotor will become worse, which will affect the use of the slip ring. The slip ring needs to be repaired, but the repair of the slip ring is relatively complicated. In many cases, the slip ring can only be directly replaced, which causes waste. Utility Model Content

[0004] The purpose of the utility model is to provide a new rotor collector ring. By setting an extrusion component, specifically, by squeezing the sliding block through the rebound force of the spring, the sliding block will always be in contact with the rotor body, the contact effect will not deteriorate, and thus the use of the collector ring will not be affected. The collector ring will not need to be replaced or repaired due to poor contact effect of the sliding block, thereby reducing waste. The problem of the existing rotor constantly rubbing against the sliding block and the sliding block being easily worn under long-term friction is solved. After more wear, the contact effect between the sliding block and the rotor will deteriorate, which will affect the use of the collector ring and require repair of the collector ring. However, the repair of the collector ring is relatively complicated, and in many cases the collector ring can only be directly replaced, resulting in waste.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is a novel rotor slip ring, comprising a rotor body, a slip ring is rotatably connected to the right side of the rotor body, a rotary hole is opened on the right side of the slip ring, a rotating ring is rotatably connected to the inner wall of the rotary hole, a plurality of sliding grooves are opened inside the slip ring, the plurality of sliding grooves are arranged in a circular array with the center of the slip ring as the center, and an extrusion assembly is arranged inside the plurality of sliding grooves;

[0007] The parts contained in several of the extrusion assemblies are the same. The extrusion assemblies include a sliding rod, a fixing ring is fixedly connected to the inner wall of the sliding groove, the inner wall of the fixing ring is slidably connected to the outer surface of the sliding rod, and a limiting ring is fixedly connected to the side of the sliding rod close to the fixing ring. The sliding rod and the limiting ring are made of insulating materials such as rubber, etc. The insulation of the material will not affect the conductivity of the sliding block, thereby not affecting the use of the merge ring. By setting up the extrusion assembly, specifically by squeezing the sliding block through the rebound force of the spring, the sliding block will always be in contact with the rotor body, the contact effect will not be deteriorated, thereby not affecting the use of the merge ring, and the merge ring will not need to be replaced or repaired due to poor contact effect of the sliding block, thereby reducing waste.

[0008] Furthermore, the outer surface of the limit ring is slidably connected to the inner wall of the sliding groove, a sliding hole is opened on the side of the inner wall of the sliding groove away from the limit ring, and a sliding wire block is slidably connected to the inner wall of the sliding hole, and the movement distance of the sliding block is limited by the contact between the limit ring and the fixed ring. The sliding wire block can directly pass through the sliding hole and then enter the sliding groove, so that the collector ring will not be affected when it is installed on the rotor body.

[0009] Furthermore, the side of the sliding block close to the fixed ring is fixedly connected to the side of the sliding rod away from the limiting ring, and a spring is sleeved on the outer surface of the sliding rod, so that when the sliding rod moves, it can also drive the sliding block to move together.

[0010] Furthermore, the side of the spring away from the fixed ring is fixedly connected to the side of the sliding block close to the fixed ring, and the side of the spring away from the sliding block is fixedly connected to the side of the fixed ring close to the sliding block. Through the rebound force of the spring, the spring is squeezed when the sliding block moves into the sliding groove. When the squeezing force disappears, the rebound force will bounce the sliding block back to contact the rotor body.

[0011] Furthermore, a plurality of square grooves are provided on the right side of the swivel, and a plurality of arc grooves are provided on the left side of the swivel. The plurality of arc grooves are arranged in a circular array with the center of the merge ring as the center, and the parts contained in the plurality of arc grooves are the same. By setting the swivel, specifically by inserting a tool into the square groove of the swivel, and then driving the swivel to rotate clockwise, a plurality of sliding blocks can be simultaneously entered into the sliding groove, which will not affect the installation of the merge ring to the rotor body, thereby saving time and improving the efficiency during installation.

[0012] Furthermore, a connecting rod is slidably connected to the inner wall of the arc groove, a fixed rod is fixedly connected to the right side of the limit ring, and a connecting rod is arranged on the left side of the swivel ring. The connecting rod is rotatably connected to the outer surface of the connecting rod through a swivel hole 1 away from the side of the fixed rod, and the connecting rod is rotatably connected to the outer surface of the fixed rod through a swivel hole 2 away from the side of the connecting rod. The arc shape of the arc groove can change the moving angle of the connecting rod when the connecting rod slides inside the arc groove. By changing the moving angle, the connecting rod is rotated on the surface of the connecting rod during the sliding process of the connecting rod. When the connecting rod rotates, it will synchronously rotate on the surface of the fixed rod, thereby changing the direction of the connecting rod, so that the connecting rod can push the fixed rod to move, and the movement of multiple fixed rods can be controlled simultaneously.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model sets an extrusion component, specifically, squeezes the sliding block through the resilience of the spring, so that the sliding block is always in contact with the rotor body, and the contact effect will not be deteriorated, thereby not affecting the use of the merge ring, and the merge ring does not need to be replaced or repaired due to the poor contact effect of the sliding block, thereby reducing waste.

[0015] 2. The utility model sets a swivel, specifically uses a tool to insert into the square groove of the swivel, and then drives the swivel to rotate clockwise, so that several sliding blocks can enter the sliding groove at the same time, which will not affect the installation of the merge ring to the rotor body, thereby saving time and improving the efficiency during installation.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

A sliding hole is provided on the inner wall of the sliding groove away from the limiting ring 135 , and a sliding thread block 134 is slidably connected to the inner wall of the sliding hole.

[0029] A side of the sliding block 134 close to the fixing ring 132 is fixedly connected to a side of the sliding rod 131 away from the limiting ring 135 , and a spring 133 is sleeved on the outer surface of the sliding rod 131 .
