Description

Technical Field

[0001] The utility model relates to the technical field of commutator rotors, in particular to a commutator rotor with good wear resistance. Background Art

[0002] As an important and basic equipment that is indispensable in industry, transportation, national defense and daily life, the downstream industries of motors include almost all basic industries of the national economy. As one of the core components of motors, the commutator is also growing with the development of the motor industry. The commutator is a device that converts direct current into a low-frequency square wave to supply the power supply electrode, and then converts the square wave signal measured by the measuring electrode into a pulsating direct current. It includes mechanical commutators, semi-plastic commutators, and all-plastic commutators. Structurally, the commutator is a circular shape formed by several contact plates, which are connected to each contact on the rotor respectively. The two electrodes connected on the outside are called brushes and contact them, and only two of them are contacted at the same time.

[0003] The application number is CN 217607169 U, which discloses a rotor of a wear-resistant integral end face commutator, including a rotor, both sides of the outer wall of the rotor are fixedly connected with an iron core, the inner cavity of the commutator is fixedly connected with a plastic cylinder, the inner cavity of the plastic cylinder is pressed against the outer wall of the rotor, a fastening sleeve is sleeved on one side of the outer wall of the rotor, both sides of the outer wall of the fastening sleeve are provided with a rotating mechanism, and both sides of the outer wall of the fastening sleeve are provided with a pressing mechanism. The rotor of the wear-resistant integral end face commutator is formed by the cooperation between the fastening sleeve, the support, the rocker, the concave block, the fixed block, the threaded cylinder and the latch. When the latch presses the fastening sleeve, the concave block presses the plastic cylinder through the fixed block, so that the plastic cylinder and the commutator can be firmly fixed on one side of the outer wall of the rotor. At this time, the end of the coil can be welded to the terminal of the commutator, which solves the problem of unstable fixation between the commutator and the rotor.

[0004] However, there is a disadvantage. When the device is in use, if the commutator is damaged, it is necessary to first loosen the bolts, remove the fastening sleeve, remove the entire retaining ring, and finally remove the commutator. This is inconvenient when the commutator is damaged. Even if the commutator is replaced, it is relatively inconvenient. Therefore, a commutator rotor with good wear resistance that can be easily replaced is needed. Summary of the invention

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

[0006] The utility model discloses a commutator rotor with good wear resistance, comprising a rotating shaft and a rotor fixed on the rotating shaft, one side of the rotor is provided with a clamping fixing structure for clamping, the clamping fixing structure comprises a fixing sleeve fixedly connected to one side of the rotor and an annular plate fixedly connected to one side of the clamping fixing structure.

[0007] Furthermore, the clamping and fixing structure also includes a compression spring evenly arranged on the outer wall of the rotor and a clamping block arranged outside the annular plate. The other side of the compression spring is fixedly connected to the annular plate, and a telescopic spring is arranged inside the clamping block. The clamping block and the annular plate are slidably connected, thereby achieving the clamping and fixing of the commutator and facilitating the replacement of the commutator.

[0008] Iron cores are evenly arranged on the outside of the rotor, and the iron cores are used for winding electric wires.

[0009] The clamping fixing structure also includes a threaded barrel rotatably connected to the fixing sleeve, the inner thread of the threaded barrel is connected to a threaded rod, and one side of the threaded rod is rotatably connected to the insertion rod.

[0010] A commutator is arranged on the outside of the card block, a card connection hole is arranged on the inside of the commutator, and jacks are arranged on both sides of the commutator. The jacks and the insertion rods are used in conjunction with each other, and the card connection holes and the card block are used in conjunction with each other. The open end of the wire is fixedly connected to one end of the commutator, thereby achieving the effect of card connection and fixation of the commutator, which facilitates the replacement of the commutator.

[0011] The utility model has the following beneficial effects:

[0012] (1) The utility model provides a clamping and fixing structure. When commutators of different sizes are placed on the surface of the annular plate, the clamping block is inserted into the interior of the commutator to complete the first clamping and fixing of the commutator. The threaded rod is rotated to adjust the threaded rod to a suitable height. The insertion rod is inserted into the interior of the insertion hole to complete the second fixing of the commutator, thereby achieving the effect of clamping and fixing the commutator and facilitating the replacement of the commutator.

[0013] (2) The utility model: by providing the threaded barrel and the threaded rod, when the commutator is fixed for the second time, the threaded rods of different heights can be adjusted, thereby achieving the effect of fixing commutators of different sizes.

[0014] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
