Description

Technical Field

[0001] The utility model relates to the technical field of filleting machines, in particular to an electric metal-impregnated graphite carbon strip filleting machine. Background Art

[0002] The pantograph in the rail transit system is responsible for current collection. Its main current-collecting component is graphite carbon strips. In urban rail transit, a DC voltage of about 1500V is used, and the current often exceeds 2000 amperes. In order to ensure the stability of current collection, most of them use metal-impregnated graphite carbon strips to ensure that they can meet the requirements of high current.

[0003] However, the carbon slide plate rubs against the contact line in a zigzag motion during operation. During high-speed movement, the contact line and the carbon strip form a right-angle contact, which resembles cutting. In order to reduce this cutting state, existing carbon slide plate manufacturers will round off the corners on both sides before leaving the factory. The typical one is R3, a fan-shaped with a diameter of 3mm.

[0004] In the rail transit system, after a new carbon skateboard has been in operation for a period of time, the rounded corners will be worn out, resulting in a vertically intersecting cutting state. Therefore, an electric metal-impregnated graphite carbon strip rounding machine is proposed to solve the above problem. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-6 An electric metal-impregnated graphite carbon bar filleting machine comprises a handle 1 and a housing 3 fixedly connected to the top, a flange cover 11 is detachably provided at one end of the housing 3, a filter screen 5 for filtering dust is fixedly connected to the inner wall of the flange cover 11, a motor 2 is installed inside the housing 3, a milling cutter shaft 13 is connected to the output end of the motor 2 through a coupling 4, and a fan 12 for dust collection is provided on the surface of the milling cutter shaft 13 at the end opening of the flange cover 11;

[0024] It should be noted that the motor 2 drives the milling shaft 13 to rotate, and the milling shaft 13 drives the fan 12 to rotate to form a pressure difference, which can suck the dust generated by grinding the graphite edges into the inner side of the flange cover 11, and under the filtering effect of the filter 5, the dust absorption and collection function can be realized.

[0025] The milling cutter shaft 13 is arranged to penetrate the filter screen 5 and the flange cover 11 , and an R-shaped milling cutter 7 is detachably arranged on the surface of the milling cutter shaft 13 near the fan 12 .

[0026] It should be noted that the R-type milling cutter 7 is detachable, and different types of R-type milling cutters 7 can be replaced to grind the edges and corners of the graphite carbon strip into the required rounded corners.

[0027] A limit bearing 8 is provided at one end of the milling cutter shaft 13 close to the R-type milling cutter 7 .

[0028] It should be noted that the limit bearing 8 can realize the side limit function of the graphite carbon strip, and cooperate with the running flange 6 to achieve standardized fillet;

[0029] It is worth noting that the setting of the limit bearing 8 can prevent the milling shaft 13 from contacting the side wall of the graphite carbon strip, thereby ensuring that the rotation of the milling shaft 13 is not affected by the graphite carbon strip.

[0030] A running flange 6 is detachably provided at the end of the flange cover 11 . A plurality of turning grooves are provided on the surface circumference of the running flange 6 . A roller 9 is rotatably connected to the inner side of the turning groove.

[0031] It should be noted that the running flange 6 can run in contact with the surface of the graphite carbon strip, making it easier for the R-type milling cutter 7 to run along the edges and corners of the graphite carbon strip, thereby facilitating the rounding and chamfering of the edges and corners.

[0032] The bottom of the roller 9 is flush with the top of the R-type milling cutter 7, ensuring that the R-type milling cutter 7 rounds the corners of the graphite carbon strip.

[0033] A lithium battery 14 and a power supply system based on the lithium battery 14 are installed inside the handle 1 , and a power switch 10 for controlling the power on and off is arranged on the surface of the handle 1 .

[0034] When the utility model is used, the power switch 10 is turned on, so that the lithium battery 14 supplies power to the motor 2, the motor 2 drives the milling cutter shaft 13 to rotate through the coupling 4, and the milling cutter shaft 13 drives the fan 12 and the R-type milling cutter 7 to rotate, and then the running flange 6 contacts the surface of the graphite carbon strip, and at the same time, the limit bearing 8 contacts the side wall of the graphite carbon strip, so that the R-type milling cutter 7 can round the corners of the graphite carbon strip, and then the R-type milling cutter 7 is controlled to go around the graphite carbon strip for one circle, which can realize the rounding and chamfering function of the corners of the graphite carbon strip, thereby realizing the standardization function of the rounding and improving the efficiency of the rounding and chamfering;

[0035] The dust generated by chamfering can be sucked into the inner side of the flange cover 11 under the pressure difference formed by the fan 12. Under the filtering effect of the filter 5, the dust absorption and collection function can be realized, and the generated dust can be absorbed and collected to avoid the workers from inhaling it into their bodies, thus ensuring a clean and sanitary working environment.

[0036] By removing the flange cover 11 from the housing 3 , the collected dust can be taken out, thereby achieving the cleaning function of the filter screen 5 .

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
