Description

The core rotation type permanent magnetic chuck
The utility model belongs to the magnetic force workbench that is used for fixing workpiece in the machining on the grinding machine.
The magnetic force workbench that is used for fixing workpiece at present in the machining mainly contains magnechuck and permanent magnetic chuck two big classes.Magnechuck adsorbs fixation workpiece by electromagnetic conversion, because energising produces thermal deformation, influential to some precision part, ultra-thin precision, if having a power failure in the process, workpiece flies out easily and hurts sb.'s feelings.Permanent magnetic chuck is the novel worktable that development in recent years is got up, its operation principle is to adopt the permanent magnetism magnetic source, rotate the swing of drive eccentric shaft with handle, make eccentric mounting and planker translation certain distance, utilize panel every magnetosphere, the logical magnetic of control magnetic source with every magnetic, not electricity consumption, do not have temperature rise, use more safe and reliable.Weak point is that magnetic force is not concentrated, on panel, evenly distribute, there is not the high magnetic force centrostigma, magnetic force can not be concentrated and use and reasonable distribution magnetic force, general workpiece processing is adapted to, processing to some special workpiece is then incompatible, and the scope of application has certain limitation, can't satisfy the processing request (seeing machine tool accessories factory, Linqing permanent magnetic chuck) of different workpieces fully.
The purpose of this utility model just provides a kind of novel permanent magnetic sucker, and is simple in structure, is convenient to install and use, and can concentrate magnetic force to satisfy the absorption requirement of difformity workpiece processing, guarantees the workpiece crudy, enhances productivity.
Task of the present utility model is finished like this: design and produce a kind of core rotation type permanent magnetic chuck, form by panel (5), end face suction disc (2), right angle suction disc (6), sucker (13), base plate (8) and magnetic core, panel (5) comprises main pole (4) and transition magnetic pole (3), main pole (4) is positioned at the front and back of panel (5), connect as one with some fastening bolts with panel (5) middle transitional magnetic pole (3), transition magnetic pole (3) by some pole plates (10) with every magnetosphere (11) apart from one another by assembling.Magnetic core comprises changes core (12), magnetic source (7), rotate spindle nose (1), changeing core (12) is the cylinder that has rectangle magnetic source groove (E) in the middle of two semicylinder welding two ends form, one end is integrally welded with rotation spindle nose (1), magnetic source (7) is installed in the magnetic source groove (E) that changes core (12), changes core (12) and is installed in the central through hole (D) of sucker (13).Main pole (4) is the cuboid parts of being made by mild steel, respectively end face, side, below have some connection screws.Sucker (13) is two steel cuboids that end face is connected as a single entity with connection welding block (9), and space forms magnet isolation tank (H) in the middle of it, is connected by central through hole (D) between sucker (13) both ends of the surface.Base plate (8) is used the cast aluminium flat panel production, is screwed in the bottom surface of sucker (13), plays separated magnetic effect.In order to strengthen the magnetic force pooled applications, on the two ends, the left and right sides of panel (5), be provided with end face suction disc (2) and right angle suction disc (6) respectively, be screwed, to satisfy the absorption requirement of different workpieces processing.Panel (5) is screwed the end face in sucker (13), and magnetic core is contained in the central through hole (D) of sucker (13).After finishing the assembling of core rotation type permanent magnetic chuck, can with the supporting use of lathe.During practical application, be equipped with handle on rotation spindle nose (1), the plate fixed handle makes magnetic core rotate 90 °, can control the duty and the demagnetized state of sucker.Logical magnetic under the duty, magnetic source (7) is in same direction with magnet isolation tank (H), the N utmost point of magnetic source (7) and the S utmost point are positioned at magnet isolation tank (H) both sides, the magnetic line of force must be made progress to the conduction of the S utmost point by the N utmost point and walk around magnet isolation tank (H) through panel (5), and the S utmost point that passes to magnet isolation tank (H) opposite through sucker (13) forms closed magnetic loop.Panel this moment (5) is gone up place work piece, will be held, and can process.When demagnetize in the processing back, with stick control magnetic core half-twist, magnetic source (7) is orthogonal with magnet isolation tank (H), the N utmost point and the S utmost point can form the closed-loop path respectively on magnet isolation tank (H) both sides, the magnetic line of force can not draw top panel (5), thereby reaches the demagnetization purpose, and workpiece is taken off.The right angle suction disc (6) of panel (5) mainly is applicable to the end face processing of special-shaped workpieces such as cylinder, hexahedron, and the vertical plane of right angle suction disc (6) absorption workpiece can guarantee the precision of workpiece processing end face.The end face suction disc (2) of panel (5) is suitable for processing plate type part, can directly adsorb two planes of plate type part, processes its side.Magnetic source (7) adopts the rare earth material magnet steel to make, and has stronger suction and penetration power.The suction of main pole (4) is convenient to select the workpiece placement location according to the needs of workpiece processing significantly greater than transition magnetic pole (3).
Through above-mentioned design, making, test, prove that the utility model is rational in infrastructure, easy to install, the diverse location of panel (5) can satisfy the processing absorption needs of different workpieces, and the scope of application is wider, can guarantee product quality, the efficient height, safe and reliable, reached preferably and given the meter purpose.
