Technical Field
[0001] This utility model relates to the technical field of surface polishing equipment, and in particular to a mechanical polishing device for adjusting the roughness of copper-aluminum bimetallic interfaces. Background Technology
[0002] Copper and aluminum, both widely used and possessing excellent properties, combine to create bimetallic composites with numerous unique advantages. Copper exhibits good electrical and thermal conductivity, ease of welding, low contact resistance, ease of electroplating, and an attractive appearance, while aluminum is renowned for its low cost, light weight, excellent heat dissipation, and economic efficiency. During the fabrication of copper-aluminum bimetallic composites, mechanical polishing is required to improve surface roughness, thereby increasing the bonding area and enhancing the bond strength.

A lead screw is installed between the two side plates of the U-shaped base frame, and a drive motor is connected to the lead screw. A lead screw nut is threaded onto the lead screw. Several clamping cylinders are fixed on both the front and rear sides of the lead screw nut. A clamping plate is connected to the piston rod end of the clamping cylinder. The metal plate to be ground is placed on the lead screw nut and clamped by the clamping plate. An n-shaped frame is provided on the U-shaped base frame. The two side plates of the n-shaped frame are located on both sides of the lead screw. A rotary grinding motor is installed on the top of the horizontal plate of the n-shaped frame. A grinding disc is connected to the bottom of the output shaft of the rotary grinding motor. An extended grinding disc is installed on the grinding disc. A cleaning scraper is installed on the inner side of the side plate of the U-shaped base frame through a connecting plate. A waste chip receiving box is provided on the U-shaped base frame.
[0007] The output shaft is equipped with a ring plate, and the top of the extended grinding disc is equipped with an adjusting screw. The adjusting screw passes through the ring plate, and a fixing nut is tightened on both the upper and lower surfaces of the ring plate on the adjusting screw.
[0008] A dust collection hood is installed below the horizontal plate of the N-shaped frame. A dust collection pipe is connected to the top of the dust collection hood, and the dust collection pipe is connected to an external dust collection device and a fan.
[0009] The cleaning scraper includes a middle plate, which is fixed to a connecting plate. The middle plate has outer inclined plates at both ends, and the two outer inclined plates are in a figure-eight shape.
[0010] The beneficial effects of this utility model are: This utility model can use a clamping cylinder to drive a clamping plate to clamp products of different widths. During polishing, the specific arrangement of the polishing disc and the extended polishing disc can be adjusted according to the needs, so as to better adapt to the polishing of more products of various sizes.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0020] like Figures 1 to 3 As shown, a mechanical grinding device for adjusting the roughness of a copper-aluminum bimetallic interface includes a U-shaped base frame 1, a lead screw 2, a drive motor 3, a lead screw nut 4, a clamping cylinder 5, a clamping plate 6, an n-shaped frame 8, a rotary grinding motor 9, an output shaft 10, a grinding disc 11, an extended grinding disc 12, a connecting plate 13, a cleaning scraper 14, a waste chip receiving box 15, a ring plate 16, an adjusting screw 17, a fixing nut 18, a dust suction hood 19, a dust suction pipe 20, a support plate 21, and a limiting rod 22.
[0021] A lead screw 2 is installed between the two side plates of the U-shaped base frame 1. The lead screw 2 is connected to a drive motor 3. A lead screw nut 4 is threaded onto the lead screw 2. Several clamping cylinders 5 are fixed on both the front and rear sides of the lead screw nut 4. A clamping plate 6 is connected to the piston rod end of the clamping cylinder 5. The metal plate 7 to be polished is placed on the lead screw nut 4 and clamped by the clamping plate 6. An n-shaped frame 8 is provided on the U-shaped base frame 1. The two side plates of the n-shaped frame 8 are located on both sides of the lead screw 2. A rotary polishing motor 9 is installed on the top of the horizontal plate of the n-shaped frame 8. A polishing disc 11 is connected to the bottom of the output shaft 10 of the rotary polishing motor 9. An extended polishing disc 12 is installed on the polishing disc 11. A cleaning scraper 14 is installed on the inner side of the side plate of the U-shaped base frame 1 through a connecting plate 13.

[0027] The height of the top of the clamping plate 6 is lower than the height of the upper surface of the metal plate 7 to be polished, which makes polishing easier and avoids interference.
[0028] This utility model can use the clamping cylinder 5 to drive the clamping plate 6 to clamp products of different widths. During polishing, the specific arrangement of the polishing disc 11 and the extended polishing disc 12 can also be adjusted according to the needs to better adapt to polishing products of more sizes. The waste on the surface of the polished product can be scraped off, saving the subsequent cleaning process and achieving a better polishing effect.
