Description

Technical Field

[0001] The invention belongs to the field of planar target material processing devices and relates to an improved method for a planar target material clamping device. Background Art

[0002] Traditional clamping devices can easily cause bumps and scratches on products, making processing difficult.

[0003] CN209615185U discloses an electromagnetic clamp used by a grinder to grind a high-purity aluminum flat target. The electromagnetic clamp uses a first limit plate and a second limit plate with matching limit angles arranged on the corresponding sides of the electromagnetic chuck to abut against the diagonal of the high-purity aluminum flat target, and uses the magnetic attraction between the electromagnetic chuck and the two corresponding limit plates to magnetically position the limit plates, thereby locking and positioning the high-purity aluminum flat target. The electromagnetic clamp overcomes the problem that the electromagnetic chuck cannot magnetically position weakly conductive magnetic bodies such as high-purity aluminum flat targets. The electromagnetic clamp has a simple structure, is easy to use, does not damage the high-purity aluminum flat target, and has accurate positioning.

[0004] CN211760778U discloses a CNC machining fixture for a flat target surface, including a plurality of unit fixtures, each of which is provided with a fixture base, a positioning block and a top block. The fixture base is fixedly connected to the milling machine platform, and the fixture base is provided with a top block adjustment mechanism, and the top block adjustment mechanism is connected to the top block; the positioning block is fixedly connected to one side of the top surface of the fixture base, and a clamping block is fixedly connected to the inner side surface of the positioning block; the top block is slidably installed on the top surface of the fixture base, and another clamping block is fixedly connected to a side of the top block close to the positioning block, and the top block and the positioning block move relatively close to and away from each other; the inner side surface of the clamping block is movable against the corresponding side edge of the workpiece, and the machined surface of the workpiece is higher than the top surface of the clamping block. The CNC machining fixture structure positions the workpiece by using a plurality of unit fixtures arranged side by side, and the tooling structure is stable and reliable, and the grinding quality is good.
