A grinder device for radiator processing

Abstract

The invention discloses a grinder device for radiator processing, which relates to the field of radiator processing, including a body, the body is provided with a support frame, a motor and a grinding wheel, the motor drives the grinding wheel, and a driving shaft: its Driven by a motor, the flexible shaft mechanism: includes a central column and an elastic telescopic sleeve assembly, the elastic telescopic sleeve assembly includes a plurality of axial members, two adjacent axial members are connected by a first elastic assembly, and the plurality of The axial member and the first elastic component form a cylindrical structure, and the cylindrical structure is sleeved on the central column and sleeved in the central hole of the drive shaft. In the present invention, when the grinding pressure of the grinding wheel is greater than the preset value, the grinding wheel is moved upwards, so that the flexible shaft is deformed, and the grinding pressure between the grinding wheel and the radiator is always kept at the preset value, which improves the grinding accuracy and avoids Excessive sanding.

Description

technical field [0001] The invention relates to radiator processing technology, in particular to a grinder device for radiator processing. Background technique [0002] In the manufacturing process of the radiator, the radiator needs to be welded and formed to form a single radiator fin, and then assembled to form a complete radiator. After the single-piece heat sink is welded and formed, it is necessary to grind the leaking weld seam on the side of the head, and then carry out follow-up treatment such as painting; and then inflate for air tightness inspection. [0003] For example, the authorized announcement number is CN201810335168.6, the authorized announcement date is September 11, 2018, and the invention patent named "201810335168.6" includes a support frame, which is equipped with a worktable driven by a lifting power mechanism. The workbench is equipped with a support seat that slides longitudinally along the workbench. The support seat is connected with a rotating ...

[0003] For example, the authorized announcement number is CN201810335168.6, the authorized announcement date is September 11, 2018, and the invention patent named "201810335168.6" includes a support frame, which is equipped with a worktable driven by a lifting power mechanism. The workbench is equipped with a support seat that slides longitudinally along the workbench. The support seat is connected with a rotating seat driven by a private motor. The rotating seat is equipped with a fixture. The support frame is also connected with a work frame. Horizontal grinding swing arm and horizontal power mechanism, two horizontal grinding rollers are installed on the horizontal grinding swing arm and the first grinding abrasive belt is wound on the two horizontal grinding rollers, one of the horizontal grinding rollers is driven by the power machine, and the work frame is also hinged with Two vertical grinding swing arms and a vertical power mechanism, two vertical grinding rollers are installed on the vertical grinding swing arm and a second grinding abrasive belt is wound on the two vertical grinding rollers, one of the vertical grinding rollers is powered by a power machine Drive, which mainly winds a grinding belt on the grinding roller. Because the grinding belt has a certain degree of elasticity, it can be used for flexible grinding, which improves the grinding accuracy and effectively prevents excessive grinding caused by rigid grinding. During the grinding process, the grinding roller is flexibly deformed, so that the grinding accuracy is not very high

[0004] In the prior art including the above-mentioned patents, when the user grinds the heat sink, it is difficult to accurately adjust the distance between the grinding wheel and the welding point, and it is easy to cause excessive grinding on the welding point, making the welding point too thin , affecting the airtightness of subsequent use
