Description

Technical Field

[0001] This utility model relates to the field of carbon commutators, specifically to a carbon commutator structure that is easy to maintain. Background Technology

[0002] A carbon commutator is an important component of the armature of DC motors and AC commutator motors. It plays a commutation role when the motor rotates. It is a component in DC motors and AC series motors that performs current commutation in order to keep the motor rotating. It is commonly known as a commutator.

[0003] The main components of a carbon commutator are insulators, commutator segments, and wire bonding structures. A typical carbon commutator has an inner insulator, a middle commutator segment, and an outer wire bonding structure. The wire bonding structure is used to weld copper wires. Each of these multiple bonding structures typically corresponds to an individual commutator segment and is connected to the copper wires as an independent unit. Therefore, when replacing or repairing a carbon commutator, if it is disassembled and reassembled, copper wires need to be individually welded to each wire bonding structure during subsequent installation. This results in a significant amount of manpower and time being spent on welding. Therefore, a carbon commutator structure is needed to solve this problem. Utility Model Content

[0004] This utility model aims to solve the technical problems mentioned in the background section above, and proposes the following technical solutions:

[0005] A carbon commutator structure for easy maintenance includes an insulating component, several commutator segments, and a wire bonding structure. The insulating component is a cylindrical structure, and the commutator segments are fixed to the outer periphery of the insulating component. A groove is provided on the bottom of one side of each commutator segment. The wire bonding structure includes a wire bonding mounting ring and a wire bonding frame. The wire bonding mounting ring has several wire bonding frame mounting holes, the positions and number of which correspond to the positions and number of the several commutator segments. The wire bonding frame includes a welding head, a fixing base, and a fixing block. The fixing base is installed in the wire bonding frame mounting holes and is fixedly connected to them. The welding head is connected to one end of the fixing base and is located outside the wire bonding mounting ring. The fixing block is connected to the other end of the fixing base and is located inside the wire bonding mounting ring.

[0006] Preferably, the groove is an inverted trapezoidal structure with a low center and high sides, and the top of the fixing block is a rounded structure.

[0007] Preferably, the fixing block is provided with a spring sheet.

[0008] Preferably, the fixed base has a spring mounting hole on the side near the inner wall of the welding wire mounting ring, a spring is installed in the spring mounting hole, a moving rod is installed at the bottom of the fixed block, the moving rod is located in the spring mounting hole, and one end of the spring is fixedly connected to the bottom of the moving rod.

[0009] Preferably, a plurality of positioning inserts are provided on the inner side of the wire bonding mounting ring. The positioning inserts are insulated and are located between two adjacent commutator segments.

[0010] The beneficial effects of this utility model are:

[0011] 1. By separating the wire bonding structure from the commutator segment and connecting it with a fixing block and a groove, it is possible to replace and repair the wire bonding structure without re-soldering the copper wires, saving a lot of manpower and time costs, and avoiding welding errors.

[0012] 2. By setting a spring on the fixed block, when the fixed block is embedded in the groove, the spring can adaptively abut against the bottom of the groove, so that the wire bonding frame will not wobble relative to the commutator due to the gap between the fixed block and the groove.

[0013] 3. By setting a spring and controlling the position of the moving rod through the extension and contraction of the spring, the fixed block can be abutted against the groove, thus avoiding the problem of the welding frame wobbling relative to the commutator segment due to the gap between the fixed block and the groove.

[0014] 4. By setting positioning inserts, the positioning inserts can be inserted into the gaps between adjacent commutator segments, enabling quick installation and positioning, which facilitates the replacement of carbon commutators by staff. Attached Figure Description

The fixed base 3-22 is installed in the wire bonding frame mounting hole 3-3 and is fixedly connected to the wire bonding frame mounting hole 3-3. The welding head 3-21 is connected to one end of the fixed base 3-22 and is located outside the wire bonding mounting ring 3-1. The fixing block 3-23 is connected to the other end of the fixed base 3-22 and is located inside the wire bonding mounting ring 3-1. The fixing block 3-23 is used to be embedded into the groove 2-1 on the commutator 2 to achieve fixation. The wire bonding frame 3-2 is a conductor as a whole.
