Description

Technical Field

[0001] The present application relates to the technical field of carbon brush production, and in particular to a chamfering device for carbon brush production. Background Art

[0002] A carbon brush is a common electrical component, usually used to transfer electrical energy to a rotating part, such as the rotor of a motor or generator. It is made of carbon powder and a conductive material (usually carbon) and is usually rectangular, cylindrical or other specific shapes.

[0003] During the production process of carbon brushes, sharp edges or corners may cause accidental scratches or damage. Chamfering can reduce these potential safety risks. Currently, the steps for chamfering carbon brushes are relatively complicated, and it is difficult to chamfer the four corners of the rectangular carbon brush body at the same time, which can easily cause uneven wear on the edges of the carbon brushes. Utility Model Content

[0006] Preferably, the chamfering mechanism includes an electric push rod fixedly mounted on the top of the tripod, the output end of the electric push rod is fixedly connected to a disc, and the outer surface of the disc is slidably connected to the inner side of the guide arc plate. Through the chamfering mechanism, the chamfering knife can chamfer the four corners of the carbon brush surface during the back and forth movement of the carbon brush surface.

[0007] Preferably, a straight rod is fixedly connected to the bottom of the disc, and a concave plate is fixedly connected to the bottom of the straight rod.

[0008] Preferably, several groups of chamfering knives are arranged on the inner side of the concave plate, and the chamfering knives are of L-shaped design. The general shape of the chamfering knives is L-shaped, but the inner corners thereof are of arc-shaped design, so as to reduce the generation of sharp corners.

[0009] Preferably, the retaining mechanism includes a guide rod fixed on the inner side of the base, the inner surface of the base is rotatably connected to a screw, a knob is provided at one end of the screw, and the outer surface of the screw is provided with threads of the same length and opposite directions from the middle position to both ends, so as to allow the two sets of shift plates to move in opposite directions.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The chamfering equipment for carbon brush production stabilizes the carbon brush in a suitable position through a retaining mechanism. The chamfering mechanism allows the concave plates stuck at the outer four corners of the carbon brush to cooperate with the chamfering knife to perform stable chamfering on the four corners of the carbon brush at the same time. This chamfering treatment can make the edge of the carbon brush smoother, avoid accidental injuries, and improve the safety of the working environment.

[0013] 2.

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] See also Figure 1-5 A chamfering device for carbon brush production includes a tripod 1, a fixing rod 2 is fixedly connected to the outer surface of the tripod 1, a guide arc plate 3 is arranged on the side of the outer surface of the fixing rod 2 away from the tripod 1, a base 4 is fixedly connected to the inner bottom of the tripod 1, a clamping frame 5 is fixedly installed on the top of the base 4, a chamfering mechanism is arranged on the tripod 1, and a retaining mechanism is arranged on the top of the base 4.

[0022] Through the above technical solution, the device can stably limit the carbon brush through the retaining mechanism when in use, so that it remains stable during the chamfering process, and then the four corners of the outer periphery of the carbon brush can be chamfered through the chamfering mechanism.

[0023] Specifically, the chamfering mechanism includes an electric push rod 6 fixedly mounted on the top of the tripod 1 , the output end of the electric push rod 6 is fixedly connected with a disk 7 , and the outer surface of the disk 7 is slidably connected to the inner side of the guide arc plate 3 .

[0024] Through the above technical solution, three groups of guide arc plates 3 are designed and evenly distributed in the tripod 1. Their function is to guide the disc 7 to move up and down stably along a fixed track.

[0025] Specifically, a straight rod 8 is fixedly connected to the bottom of the disc 7 , and a concave plate 9 is fixedly connected to the bottom of the straight rod 8 .

[0026] Through the above technical solution, two groups of straight rods 8 are designed, which are respectively connected to two groups of concave plates 9 at the bottom.

[0027] Specifically, a plurality of groups of chamfering knives 10 are arranged on the inner side of the concave plate 9, and the chamfering knives 10 are of L-shaped design.

[0028] Through the above technical solution, the L-shaped design of the chamfering knife 10 is to fit the four corners of the carbon brush, and the inner corner of the L-shape of the chamfering knife 10 is designed to be arc-shaped, which can reduce the generation of sharp edges.

[0029] Specifically, the retaining mechanism includes a guide rod 11 fixed to the inner side of the base 4 , a screw rod 12 is rotatably connected to the inner surface of the base 4 , and a knob 13 is provided at one end of the screw rod 12 .

[0030] Through the above technical solution, the outer surface of the screw rod 12 is provided with threads of the same length and in opposite directions from the middle position to both ends, so that the two sets of shift plates 14 will move in opposite directions along the screw rod 12 during the rotation of the screw rod 12 .

[0031] Specifically, a shift plate 14 is threadedly sleeved on the outer surface of the screw rod 12 , and the inner surface of the shift plate 14 is slidably connected to the outer surface of the guide rod 11 , and a clamping seat 15 is provided on the top of the shift plate 14 .

[0032] Through the above technical solution, the side where the two groups of holders 15 are close to each other is designed as a friction surface, the purpose of which is to increase the contact friction with the carbon brush and reduce the sliding of the carbon brush.

[0033] Working principle: When the device is in use, the carbon brush is first placed at a suitable position on the base 4, and the screw 12 can be driven to rotate by turning the knob 13. Since the outer surface of the screw 12 is provided with threads of the same length and opposite directions from the middle position to both ends, under the limiting action of the guide rod 11, the two groups of shift plates 14 will move in opposite directions along the screw 12, and then link the two groups of card seats 15 to approach each other until the carbon brush is firmly stabilized, and then the electric push rod 6 is turned on, and the two groups of straight rods 8 will stably move the concave plate 9 up and down along a fixed trajectory through the stable guidance of the guide arc plate 3 to the disc 7. In the process of sliding up and down along the inner side of the card holder 5, the chamfering knife 10 at the inner corner will scrape back and forth along the four corners of the carbon brush, and the chamfering knife 10 with a similar L-shaped design, combined with the design of a slightly arc-shaped corner, can remove the protrusions at the four corners in the process of chamfering the four corners of the carbon brush back and forth, effectively reducing the generation of sharp edges, thereby effectively chamfering the four corners of the carbon brush at the same time, reducing the risk of scratches or damage to the carbon brush during production and use. This chamfering process can make the edge of the carbon brush smoother, avoid accidental injuries, and improve the safety of the working environment.

[0034] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
