Abstract
The utility model relates to a magnetism conversion device which comprises a sleeve, wherein a rotating shaft is arranged at the back end of the sleeve, and the sleeve is provided with an accommodating cavity which is rearwardly concave from the front end; a magnet and a stopper positioned in front of the magnet are arranged in the accommodating cavity, and the stopper is positioned on the sleeve; and a mounting hole which extends inwards and is used for installing a screwdriver lever is arranged on the front end surface of the stopper. When the magnetism conversion device is used, the screwdriver lever is inserted into the mounting hole and can be directly magnetized by the preset magnet in advance.
Description
Technical field
The utility model relates to a kind of magnetic conversion equipment.
Background technology
In assembly line or otherwise assembling, maintenance, when adopting nut or screw to carry out the parts assembling, bring difficulty to assembly work because screwdriver (or spanner) head is nonmagnetic.Because screwdriver rod is a consumable accessory, need usually change, and the magnetized screwdriver rod price of special-purpose process is high, if in Assembling Production in enormous quantities, adopt the special-purpose magnetized screwdriver rod of process, production cost is increased.At present also there is not a kind of normal screws knife bar that makes to have the magnetic conversion equipment of magnetic.
Summary of the invention
Also do not have a kind of normal screws knife bar that makes to have the magnetic conversion equipment of magnetic in view of in the prior art, the utility model provides a kind of normal screws knife bar that makes to have the magnetic conversion equipment of magnetic.
The technical scheme that the utility model solves its technical problem is: a kind of magnetic conversion equipment; Comprise sleeve; The rear end of said sleeve is provided with power transmission shaft, and described sleeve has from the front end containing cavity of indent backward, is provided with magnet in the described containing cavity and is positioned at the block in said magnet the place ahead; Described block is positioned on the described sleeve, offers the installing hole that is used to install screwdriver rod that extends internally on the front end face of said block.
Further, described bush outer sleeve is provided with outer sleeve, is threaded between described outer sleeve and the described sleeve; The front end of said outer sleeve is provided with opening, and the front end of said block is provided with the extension, and stretch out from described opening said extension, and the block at rear, said extension is sandwiched between the front end face and magnet of outer sleeve.
Further; Described block is provided with groove radially; Spiral shell is provided with double-screw bolt in the described groove, and said double-screw bolt has spring cavity, thereby described spring cavity extends formation steel ball mouth on the inner at double-screw bolt to the inner of double-screw bolt; Be provided with stage clip and steel ball in the described spring cavity, thereby described steel ball part under the active force of said stage clip exposes to and makes outside the said steel ball mouth that described steel ball is local to be got in the described installing hole.
The utility model is inserted into screwdriver rod in the installing hole and gets final product in use, owing to preset magnet in advance, therefore can directly realize the magnetization of screwdriver rod.
The beneficial effect of the utility model is: provide a kind of normal screws knife bar that makes to have the magnetic conversion equipment of magnetic, can realize the magnetization of normal screws knife bar, and screwdriver rod is convenient to change.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation of double-screw bolt.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further explain.
With reference to Fig. 1, Fig. 2, a kind of magnetic conversion equipment comprises sleeve 1, and the rear end of said sleeve 1 is provided with power transmission shaft 2, and power transmission shaft 2 is used to connect electric screw and instrument such as criticizes.Described sleeve 1 has from the front end containing cavity of indent backward; Be provided with magnet 3 in the described containing cavity and be positioned at the block 4 in said magnet 3 the place aheads; Described block 4 is positioned on the described sleeve, offers the installing hole that is used to install screwdriver rod 5 that extends internally on the front end face of said block 4.
In the present embodiment, the concrete locate mode of block 4 is: be threaded between the described sleeve 1 outer outer sleeve 6 that is arranged with, described outer sleeve 6 and described sleeve 1; The front end of said outer sleeve 6 is provided with opening, and the front end of said block is provided with extension 7, and stretch out from described opening said extension 7, and the block at 7 rears, said extension is sandwiched between the front end face and magnet 3 of outer sleeve 6.
In the present embodiment; Described block 4 is provided with groove 8 radially; Spiral shell is provided with double-screw bolt 9 in the described groove 8, and said double-screw bolt 9 has spring cavity, thereby described spring cavity extends formation steel ball mouth on the inner at double-screw bolt to the inner of double-screw bolt 9; Be provided with stage clip 10 and steel ball 11 in the described spring cavity, thereby described steel ball 11 part under the active force of said stage clip 10 exposes to and makes said steel ball mouth outside in the described installing hole of described steel ball 11 local entering.
In use, screwdriver rod 5 is inserted in the installing hole gets final product, can make screwdriver and use.The draw-in groove that screwdriver rod 5 design and steel ball 11 are adaptive, steel ball 11 snapped in draw-in groove and accomplishes assembling when screwdriver rod 5 inserted.Owing to preset magnet 3 in advance, therefore can directly realize the magnetization of screwdriver rod 5.
It is hexagonal hole that installing hole also can be designed to cross section, and screwdriver rod is adaptive with it, and screwdriver rod directly inserts installing hole and gets final product.
Claims (3)
