Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a polishing mechanism, particularly a polishing mechanism for copper wires of motor stators. Background Technology

[0002] When the copper wires of the motor stator are exposed, an oxide film will form on them. During assembly, the copper wires need to be polished to remove the oxide film.

[0003] Existing polishing equipment, such as the abrasive copper wire polishing machine disclosed in the Chinese Patent Database (application number: 201520617639.4), includes a base plate. From left to right, the upper surface of the base plate is provided with a power unit, a second support plate, and a first support plate. The power unit is connected to an external power source. The power unit is characterized by: a second drive shaft at its right end; a first drive shaft at its left end; the first drive shaft connected to the second drive shaft via a drive belt; a turntable at its right end; the second drive shaft connected to the turntable via a drive rod passing through the second support plate; an abrasive disc at its right end; a base plate at its left end; and an abrasive disc at its left end. The tops of the first and second support plates are connected by a baffle, the front surface of which has multiple wire inlets.

[0004] In the aforementioned polishing machine, copper wire passes through an inlet hole and enters between two abrasive blades for polishing. Because the copper wire is soft, and the two abrasive blades are in contact with the wire during polishing, the wire's feed is obstructed and bent, affecting its feeding and consequently impacting the machine's performance. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a polishing mechanism for motor stator copper wires that provides a better polishing effect.

[0006] The objective of this utility model can be achieved through the following technical solution: a motor stator copper wire polishing mechanism, comprising a base plate, characterized in that a lifting plate and a power mechanism for driving the lifting plate to rise and fall are horizontally provided above the base plate; a bracket is fixed on the upper side of the base plate, and a pair of rotating shafts are horizontally rotatably arranged on the bracket, with polishing wheels coaxially arranged with the corresponding rotating shafts fixed at one end of each rotating shaft, the two polishing wheels being arranged side by side along the arrangement direction of the two rotating shafts, and a polishing area matching the stator copper wire is formed between the two polishing wheels; the lifting plate is also provided with a drive mechanism for driving the two rotating shafts to operate synchronously.

[0007] In use, the stator is horizontally clamped by a fixture so that the stator copper wire extends vertically into the polishing area, and the oxide film attached to the outer surface of the stator copper wire is removed by the rotation of two polishing wheels.

[0008] During polishing, the stator copper wire is sandwiched between two polishing wheels. Under the action of the power mechanism, the two polishing wheels always move the stator copper wire upward or downward, which ensures that the stator copper wire is always in a vertical position during polishing, ensuring that the polishing process is stable and precise, thereby effectively improving the polishing quality.

[0009] In the aforementioned motor stator copper wire polishing mechanism, the drive mechanism includes a rotary motor fixed on the lifting plate, and the rotary motor drives two rotating shafts to rotate through a transmission structure. This design offers advantages such as simple structure and convenient installation.

[0010] In the aforementioned motor stator copper wire polishing mechanism, the transmission structure includes a driving pulley and driven pulleys. The driving pulley is fixed to the main shaft of the rotating motor, and there are two driven pulleys, each fixed to the other end of one of the two rotating shafts. The driving pulley and the two driven pulleys are connected together by a belt. The motor drives the two rotating shafts through belt drive, which has the advantages of simple structure and stable operation. Furthermore, the elasticity of the belt can effectively mitigate impact and vibration, protecting connected equipment.

[0011] In the aforementioned motor stator copper wire polishing mechanism, a base for mounting the rotary motor is provided on the lifting plate. The base can slide along the arrangement direction of the two rotating shafts and be locked in the sliding position. Sliding the base along the arrangement direction of the two rotating shafts facilitates belt tension adjustment and assembly.

[0012] In the aforementioned motor stator copper wire polishing mechanism, a tensioning wheel is also rotatably mounted on the frame, and the tensioning wheel meshes with the inner side of the belt to keep the belt taut and make it run more stably.

[0013] In the aforementioned motor stator copper wire polishing mechanism, the base includes two connecting plates distributed along the two rotating shafts. Both connecting plates are slidably connected to the lifting plate and can be locked in the sliding position. The aforementioned rotary motor is located between the two connecting plates. This design increases the positioning strength and stability of the rotary motor, thereby ensuring its stable operation.

[0014] In the aforementioned motor stator copper wire polishing mechanism, a sliding groove with an inverted T-shaped cross-section is provided on the top surface of the lifting plate, and the length of the sliding groove extends along the distribution direction of the two rotating shafts; each connecting plate is provided with at least one sliding groove, and a matching T-bolt is slidably provided in the sliding groove, the connecting plate is pressed on the lifting plate, and a threaded hole for the corresponding T-bolt to be screwed into is vertically passed through the connecting plate.

[0015] As another option, in the above-mentioned motor stator copper wire polishing mechanism, a linear guide rail is horizontally fixed on the top surface of the lifting plate, and the length of the linear guide rail extends along the distribution direction of the two rotating shafts. A locking slider is installed on the linear guide rail, and at least one locking slider is fixedly connected to each of the two connecting plates.

[0016] In the aforementioned motor stator copper wire polishing mechanism, the lifting plate and the base plate are slidably connected up and down. The power mechanism includes a lifting motor, which is connected to the lifting plate through a screw and nut transmission structure. It has the advantages of simple structure and stable operation.

[0017] As an alternative, in the aforementioned motor stator copper wire polishing mechanism, the lifting plate and the base plate are slidably connected up and down, the power mechanism includes a cylinder, and the cylinder piston rod is connected to the lifting plate.

[0018] Compared with existing technologies, the stator copper wire polishing mechanism of this motor has the following advantages:

[0019] 1. During polishing, the stator copper wire is sandwiched between two polishing wheels. Under the action of the power mechanism, the two polishing wheels always move the stator copper wire upward or downward, which ensures that the stator copper wire is always in a vertical position during polishing, ensuring that the polishing process is stable and precise, thereby effectively improving the polishing quality.

[0020] 2. The motor drives the two shafts through belt drive, which has the advantages of simple structure and stable operation. The elasticity of the belt can also be used to effectively reduce impact and vibration and protect connected equipment. Attached Figure Description

Furthermore, a tensioning wheel 10 is rotatably mounted on the frame, and the tensioning wheel 10 engages with the inner side of the belt 9 to keep the belt 9 taut, making its operation more stable.

Sliding the base 11 along the arrangement direction of the two rotating shafts 4 facilitates the adjustment of the belt 9 tension and facilitates assembly.

[0034] The mounting method of the base 11 is as follows: The base 11 includes two connecting plates 11a distributed along the arrangement direction of the two rotating shafts 4. Both connecting plates 11a are slidably connected to the lifting plate 2 and can be locked in the sliding position.
