Description

Fixing device is used in processing of large-scale material

Technical Field

The utility model relates to machining equipment, in particular to a fixing device for machining large materials.

Background

The permanent magnetic chuck is also called a magnetic chuck, is a magnetic clamp widely applied in machining fields such as mechanical factories, mould factories and the like, and can greatly improve the clamping efficiency of magnetically permeable steel materials. The permanent magnetic sucker takes high-performance rare earth material neodymium iron boron (N > 40) as an inner core, and the sucker handle is manually pulled to rotate, so that a magnetic force system of neodymium iron boron in the sucker is changed, and the workpiece to be processed is sucked or released.

When a large-scale iron part is machined by traditional horizontal milling, if a plurality of sides of the iron part are required to be machined, a workbench is required to be rotated, and when the workbench is rotated in the middle, a workpiece on the workbench is easy to displace, so that errors are caused, and the machining effect is affected.

Disclosure of Invention

The utility model aims to solve the problems in the background technology and provides a fixing device for processing large materials.

The technical scheme adopted by the utility model is as follows: the utility model provides a fixing device is used in processing of large-scale material, includes work panel, first permanent magnetism module and second permanent magnetism module, first permanent magnetism module with one of them of second permanent magnetism module is fixed on the work panel, another one is movable to be set up.

Further, the first permanent magnet module comprises a chessboard permanent magnet sucker, the chessboard permanent magnet sucker is fixedly arranged on the working panel, and a workpiece to be processed is placed on the chessboard permanent magnet sucker.

Further, the second permanent magnet module comprises a jack main body, a hand lever and a hanging ring, wherein the hand lever is arranged on a rotating shaft at one end of the jack main body, the hanging ring is arranged on the central position of the top surface of the jack main body, and the jack main body is arranged at the upper end of a workpiece to be processed.

Further, the workbench surface of the chessboard permanent magnet sucker and the magnetic yoke material of the workbench surface of the jack main body are soft magnetic materials.

Further, the hanging ring is arranged on the jack main body through a fixing bolt.
