Description

Technical Field

[0001] The present application relates to the technical field of sheet metal parts, and in particular to a deburring tool for sheet metal parts. Background Art

[0002] Sheet metal parts are products processed by sheet metal technology, and are usually used in the fields of electronics, communications, automobile industry, medical equipment, etc. Sheet metal technology includes shearing, punching / cutting / compounding, folding, welding, riveting, splicing, and molding, which can produce lightweight, high-strength, conductive, and low-cost products. The sheet metal parts referred to in different industries may be different, and are mostly used in assembly.

[0003] The existing Chinese patent with announcement number CN217493902U discloses a sheet metal deburring tooling, which relates to the sheet metal processing technology field. It includes a base, a top plate and a vertical plate, the base is provided with vertical plates on both sides, a processing table is fixed on the lower side of the top plate, both sides of the processing table are fixed with limit mechanisms, a grinding mechanism is installed on the limit mechanism, a first stepper motor is fixedly installed in the support plate, the upper end of the first stepper motor passes through the support plate and the side wall of the processing table and is fixedly installed with a gear and a tooth plate, one end of the tooth plate is fixedly connected to the limit mechanism mounting plate, driving the limit mechanism to fix the outer side of the sheet metal, the limit mechanism drives the grinding mechanism to reciprocate and grind the burrs on the outer side of the sheet metal through the connecting rod in the sliding hole, the positioning plate in the positioning mechanism moves downward to fix the position of the sheet metal, the processed burrs are collected by the collection tank below, the application range is wider, and the burrs will eventually fall into the collection tank and be recycled, saving production costs.

[0004] However, the above-mentioned deburring tooling has the following disadvantages: the device can fix sheet metal parts of different thicknesses by setting a positioning mechanism, but it is not very stable to fix the sheet metal parts only by relying on the telescopic cylinder and the positioning plate. The grinding disc will vibrate when deburring the sheet metal parts, and the vibration will cause the sheet metal parts to shift in position and vibrate, thereby reducing the processing accuracy and stability of the sheet metal parts. In addition, the high-speed rotation of the grinding disc will generate a lot of heat. If the grinding disc is not cooled in time, the service life of the grinding disc will be affected.

[0005] Therefore, we propose a sheet metal deburring tool to solve this problem.
