Abstract
A non-magnetic grinding jig comprises a permanent magnet sucker, a piece of longitudinal stop iron, a piece of horizontal stop iron and a piece of angle stop iron. A rectangle region is formed by the piece of longitudinal stop iron and the piece of horizontal stop iron. A magnet blank to be processed is configurated in the rectangle region. Four corners formed by the piece of angle stop iron, the piece of longitudinal stop iron and the piece of horizontal stop iron are joined tightly. And the permanent magnet sucker is respectively attached tightly with the longitudinal stop iron, the horizontal stop iron and the angle stop iron, and is adsorbed on the face of a grinder bench. The non-magnetic grinding jig is simple in structure, low in production cost, convenient to assemble and unassemble, safe and stable, high in production efficiency and suitable for non-magnetic grinding of a vertical shaft round stage flat grinder of a high-performance sintering neodymium iron boron permanent magnet material blank.
Description
Technical field
The utility model relates to the grinding anchor clamps of a kind of machinery processing apparatus, particularly permanent-magnet material, belongs to the field of machining of rare earth permanent-magnetic material.
Background technology
Vertical surface grinding machine with round table is because it has advantages such as working (machining) efficiency height, simple to operate, good stability, and the cross grinding processing and the form and position tolerance that are widely used in the sintered Nd-Fe-B permanent magnetic material blank are proofreaied and correct.The vertical surface grinding machine with round table work top is the powerful electromagnetic sucker, and the magnechuck energising is magnetized and produced stronger electromagnetic attraction, and workpiece to be processed is fixed on work top so that processing; Magnechuck cuts off the power supply then that magnetic field disappears at once, to accomplish removing stage makeup and costume of processing work.Yet adopt casting sheet (Strip Casting; SC) quick-fried broken (the Hydrogen Decrepitation of technology and hydrogen; HD) the high performance sintered neodymium-iron-boron permanent-magnet material of prepared be easy to by the external magnetic field magnetization, so the said material blank is after the vertical surface grinding machine with round table grinding because it has high magnetic aligning degree; Be with weak magnetic easily owing to receive the influence in Grinder bench face magnechuck magnetic field; The electroplating surface that is unfavorable for product is handled, and does not find good solution at present as yet, makes very headache of many sintered Nd-Fe-B permanent magnetic materials manufacturer.
The utility model content
To the problem that prior art exists, the utility model aims to provide a kind of no magnetic grinding anchor clamps, realizes the no magnetic processing of rare earth permanent-magnetic material.
A kind of no magnetic grinding anchor clamps; Comprise permanent magnetic chuck, vertical buting iron, horizontal buting iron, angle buting iron; Vertically buting iron forms a rectangular area with horizontal buting iron; Magnet blank to be processed is arranged in the rectangular area, and the angle buting iron closely is connected with four angles of vertically buting iron and laterally buting iron formation, and permanent magnetic chuck is close to vertical buting iron, horizontal buting iron, angle buting iron respectively and is adsorbed on the Grinder bench face.
Said permanent magnetic chuck comprises magnetic conduction casing and non-magnetic conduction casing, and radial oriented sintered NdFeB cylindrical magnet is installed in magnetic conduction casing and the non-magnetic conduction casing, and 0.5～1.5mm gap is arranged between the housing, and non-magnetic conductive axis is arranged in the cylindrical magnet.
Further, said vertical buting iron is no less than 2 with the permanent magnetic chuck on horizontal each limit of buting iron.
Further, said vertical buting iron is higher than the half the of magnet blank height to be processed with the horizontal height of buting iron and is lower than the height of target product.
The utility model is simple in structure, and low cost of manufacture is easy to loading and unloading, safety and stability, and production efficiency is high, is applicable to the no magnetic grinding of the vertical surface grinding machine with round table of high performance sintered neodymium-iron-boron permanent-magnet material blank.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model permanent magnetic chuck working state schematic representation.
Fig. 3 is the utility model permanent magnetic chuck off working state sketch map.
Among the figure: 1-permanent magnetic chuck, the vertical buting iron of 2-, 3-angle buting iron, 4-magnet blank to be processed, 5-work top, the horizontal buting iron of 6-, 7-magnetic conduction casing, the non-magnetic conduction casing of 8-, 9-cylindrical magnet, the non-magnetic conductive axis of 10-.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1; The utility model does not have magnetic grinding anchor clamps; Comprise permanent magnetic chuck 1, vertical buting iron 2, horizontal buting iron 6, angle buting iron 3; Vertical buting iron 2 forms a rectangular area with horizontal buting iron 6, and magnet blank 4 to be processed is arranged in the rectangular area, and vertically buting iron 2 and horizontal 6 palpuses of buting iron stay 10～50mm gap so that pendulum is expected area size's adjustment; Angle buting iron 3 and vertical buting iron 2 closely are connected with four angles that horizontal buting iron 6 forms, and permanent magnetic chuck 1 is close to vertical buting iron 2, laterally buting iron 6, angle buting iron 3 and be adsorbed on the Grinder bench face 5 respectively.
Permanent magnetic chuck 1 comprises magnetic conduction casing 7 and non-magnetic conduction casing 8; Radial oriented sintered NdFeB cylindrical magnet 9 is installed in magnetic conduction casing 7 and the non-magnetic conduction casing 8; And 0.5～1.5mm gap is arranged between the housing; Cylindrical magnet 9 can rotate in housing 7,8, and non-magnetic conductive axis 10 is arranged in the cylindrical magnet 9.When cylindrical magnet 9 differently-s oriented directivity turned to magnetic conduction casing 7, the magnetic line of force was through magnetic conduction casing 7, Grinder bench face 5 formation loops, and permanent magnetic chuck 1 is in running order, and is as shown in Figure 2; When cylindrical magnet 9 differently-s oriented directivity turned to non-magnetic conduction casing 8, the magnetic line of force broke off, and permanent magnetic chuck 1 is in off working state, so that accomplish removing stage makeup and costume of processing magnet.
Further, vertically buting iron 2 is no less than 2 with the permanent magnetic chuck 1 on horizontal buting iron 6 each limit, and its quantity is confirmed according to the magnetic force size.
Further, vertically buting iron 2 is higher than the half the of magnet blank 4 height to be processed with the horizontal height of buting iron 6 and is lower than the height of target product.
Certainly; The utility model also can have other various embodiments; Under the situation that does not deviate from the utility model spirit and essence thereof; Those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
