Description

The Adjustable magnetic angle square

Technical field

The utility model belongs to the Magnetic tools field, and specifically, the utility model relates to a kind of Adjustable magnetic angle square.

Background technology

Current, the Magnetic tools of various different designs has been familiar with by people and has been extensive use of, as: EspositoUS4,413,417 (instrument that can regulate being adsorbed on the mach workbench) by a conventional magnet; Pignataro US4,023,267 (interlocking finger shape is inhaled Magnetic tools); MatsuhashiUS4,468,649 (a kind of permanent suction magnetic instruments of belt switch, it has nonmagnetic to move control by switch between the two poles of the earth of magnet); Also has a kind of Baermann of being US4,055,824 (a kind of permanent magnetism control device, at magnet two interpolars rotate control it and have nonmagnetic by thumb wheel).More than these several instruments to have nonmagnetic all be to slide or turn to a magnetic pole or another magnetic pole is finished by switch.Various rotary magnetic switch are operated with identical or associated method, as: Iwasaki US4,393,363; WangUS5,525,950; Levesque US2,280,437; Hernandaz US4,470,032.Alnico magnets place between two iron plates, thus by with iron plate magnetization absorption workpiece, as US4 such as Schloerb, 475,026 and Vidmar US5,491,907.

Different types of Magnetic tools can be fixed parts by required structure, with convenient welding and assembling.As: a magnetic angle square that does not have switch, utilize its magnetic to be fixed on workpiece on 90 degree or the 45 degree positions.But, following difficulty is arranged when using the Magnetic tools of no demagnetization function:

1, work magnetic force has been subjected to restriction.Using Magnetic tools to weld and during assembly work, the operator wishes that magnetic force is big as far as possible; Otherwise, fulfiling assignment, in the time of need removing instrument, wish that magnetic force is the smaller the better.Because the latter's restriction, therefore, the work magnetic force that does not have the Magnetic tools of demagnetization function when design is restricted;

2, difficulty is adjusted in workpiece absorption back.When using this instrument, usually, the operator needs to regulate the position of workpiece after using Magnetic tools absorption workpiece, make it more accurate, and this adjusting is generally manual to be carried out, and destroys workpiece and reaches higher accuracy avoiding.Workpiece adsorbs too tightly, just must overcome to fall suction and could separate the two with instrument (as hammer).But suffer from the assurance precision, then will emit or defective work piece or damage the risk of instrument.

3, preserve and carry difficulty.Because the Magnetic tools of no demagnetization function has magnetic force all the time, so must be away from the object that may be magnetized when depositing and carry, and these objects are ubiquitous.

Summary of the invention

The purpose of this utility model just is to overcome the above-mentioned shortcoming of existing Magnetic tools, thereby a kind of Adjustable magnetic angle square is provided.

For achieving the above object, Adjustable magnetic angle square of the present utility model comprises side plate and the pair of magnetic body that pair of parallel is placed, and magnetic is between two parallel side plates and can pass through switch rotation.Gauge tap can rotate magnetic, thereby changes magnetic direction.When the normal direction of side plate working face was vertical with magnetic direction, working face produced magnetic, and reaches maximum; Otherwise magnetic reaches minimum of a value, approaches zero.

During work, usually earlier the switch in the Adjustable magnetic instrument is pushed the most weak position of magnetic, allow the working face of instrument have more weak suction, can adjust two distances that are adsorbed between the workpiece this moment like a cork, after treating that the location of workpiece is adjusted, tool switch is rotated 90 degree, allow the magnetic force of tool work face reach maximum, reach the position that fixedly is adsorbed workpiece.

Therefore, use Adjustable magnetic instrument of the present utility model, can under the influence that is not subjected to magnetic force, arbitrarily adjust the location of workpiece; After in case adjust the position, just can be fixing very safely two workpiece with the magnetic force instrument.In addition, when depositing and carrying this instrument, only need with switch be allocated to the magnetic force minimum position just can exempt instrument have magnetic force all the time and bring deposit and carry the time puzzlement.
