Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing equipment, in particular to a fine grinding machine for the copper core of automobile copper parts. Background Art

[0002] In the automotive industry, copper accessories are particularly important, especially the copper core in the car battery. Since burrs will be generated during the processing of the copper core, the burrs need to be polished. Therefore, a polishing device is required during the processing of the copper core.

[0003] The patent with announcement number CN213615743U discloses a battery copper core grinding device, including a base plate, a moving mechanism, a clamping mechanism and a driving mechanism; the base plate: the four corners of its upper surface are provided with mounting holes, the upper surface of the boss on the rear side of the base plate is provided with a grinding motor, and the output shaft of the grinding motor is provided with a grinding disk; the moving mechanism: arranged in the middle of the upper surface of the base plate; the clamping mechanism: rotatably connected to the inside of the moving mechanism, the internal fixed clamp of the clamping mechanism holds the battery copper core, and the rear end of the outer surface of the battery copper core contacts the grinding disk; the driving mechanism: arranged on the upper surface of the moving mechanism, and the driving mechanism is connected to the clamping mechanism through a belt; wherein: it also includes a control switch group, the control switch group is arranged on the rear side of the upper surface of the base plate, the input end of the grinding motor is electrically connected to the output end of the control switch group, and the battery copper core grinding device, the battery copper core is in flexible contact with the grinding disk, and the material can be clamped and released conveniently and quickly.

[0004] During the specific use of the above-mentioned prior art, the output shaft of the grinding motor drives the grinding disc to rotate, and the driving mechanism drives the clamping mechanism to rotate, which drives the battery copper core to rotate. During the extension of the telescopic end of the electric push rod, the battery copper core will contact the grinding disc and then start grinding. However, the battery copper core is a cylindrical structure. During the extension of the telescopic end of the electric push rod, the grinding disc can only grind a part of the outer wall of the battery copper core, and the battery copper core cannot move forward and backward, resulting in a grinding dead angle. Therefore, the above-mentioned prior art has defects during actual use, and floating dust is easily generated during the grinding process, which affects the respiratory health of the staff. In view of this, we propose a fine grinding machine for the copper core of automotive copper accessories. Utility Model Content

[0005] The utility model aims to provide a fine grinding machine for the copper core of automobile copper accessories to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A precision grinding machine for the copper core of an automotive copper fitting, including a base. At a position near the right side of the top of the base, there is a first L-shaped bracket. At a position near the top on the left side of the first L-shaped bracket, there is a three-jaw chuck, and the three-jaw chuck is used to quickly clamp one end of the copper core to be polished.

[0008] At a position near the left side of the top of the base, there is a second L-shaped bracket. At a position near the top on the left side of the second L-shaped bracket, there is an electric telescopic rod. The movable rod of the electric telescopic rod passes through the left side of the second L-shaped bracket and is fixedly connected to a frame-shaped moving body. Inside the frame-shaped moving body, there is a motor. The output shaft of the motor passes through the right side of the inner wall of the frame-shaped moving body and is coaxially connected to a rectangular sleeve block. The rectangular sleeve block is connected with a detachable grinding piece. The grinding piece is located directly to the left of the three-jaw chuck. By driving the frame-shaped moving body to move left and right through the electric telescopic rod, the grinding piece moves towards the three-jaw chuck. By driving the rectangular sleeve block to rotate through the motor, the rectangular sleeve block drives the grinding piece to rotate, and the grinding piece grinds the outer surface of the copper core, thereby effectively removing the burrs on the outer surface of the copper core. When grinding copper cores of different models, the corresponding grinding piece can be replaced.

[0009] The grinding piece includes a circular plate. In the middle of the left side of the circular plate, there is a rectangular insertion block inserted into the rectangular sleeve block. At the edge of the right side of the circular plate, there are two arc-shaped plates arranged symmetrically in the front and back. On the concave surfaces of the two arc-shaped plates, there are arc-shaped grinding sheets. On the right side of the circular plate, there is a circular grinding sheet. When the grinding piece grinds the copper core, the two arc-shaped grinding sheets abut against the outer wall of the copper core. The grinding piece moves towards the three-jaw chuck until the circular grinding sheet abuts against the end of the copper core to grind the end of the copper core, thereby precisely grinding the outer surface of the copper core. After that, the staff takes out the clamped end of the copper core and makes the polished end be clamped by the three-jaw chuck, and then performs the grinding operation again, so that the outer surface of the copper core is comprehensively and precisely ground.

The dust removal assembly includes a dust removal box fixedly connected to the top of the base. A strip-shaped dust suction port is opened at the top of the dust removal box. A detachable first filter box and a second filter box are sequentially arranged in the dust removal box from top to bottom. The pore size of the bottom of the first filter box is larger than that of the bottom of the second filter box. The dust generated during the copper core grinding process is sucked into the dust removal box through the strip-shaped dust suction port, and then filtered by the first filter box and the second filter box in sequence, so as to achieve the function of dust removal.

[0014] Preferably, an exhaust pipe is provided on the left side of the dust removal box and near the bottom. A exhaust fan is arranged in the exhaust pipe. The exhaust pipe is located below the second filter box. The exhaust fan discharges the air in the dust removal box, so as to generate suction at the strip-shaped dust suction port and generate a downward airflow above the dust removal box.

[0015] Preferably, first U-shaped plates are provided on the left and right sides of the inner wall of the dust removal box and near the top. The first filter box is located between the two first U-shaped plates. A first operation port for the first filter box to pass through is opened on the front side of the dust removal box, which is convenient for the staff to clean the first filter box.
