The mechanism comprises a wheel shifting axis supported in a rolling mode, and a shifting wheel. The axis is fixedly connected with a belt pulley, or a chain wheel or a gear which is used for rotating the wheel shifting axis and is connected with the output axis of the speed reducer in a mechanical transmission mode. The rigid work table with of the bearing pin roller workpieces is provided with a through slot structure to enable the blade of the shifting wheel to rotate in the through slot. The demagnetizer has the advantages of low power consumption and good demagnetizing effect on the workpieces.
Description
The utility model relates to the demagnetizer that is used for the workpiece demagnetization, be specially adapted to the demagnetizer of the roller workpiece demagnetization of large-sized roller bearing.
Workpiece to be machined often has certain magnetic in the processing and fabricating of bearing, must be demagnetized.The known demagnetizer that is used for the demagnetization of large size bearing roller workpiece generally comprises frame and can produce the magnetic head of alternating magnetic field, most employing flexible conveyer belt (balata belt) carries and delivery is made the alternating magnetic field of workpiece process magnetic head generation and realizes demagnetization by the workpiece that demagnetizes, the problem that exists is because the large size bearing roller is heavier, the conveyer belt load is excessive, useful life is very short, and the demagnetizer maintenance cycle is too short; Because due to the conveyer belt flexibility, cause the scraggly change in flexibility of conveyer belt, force workpiece and magnetic head must keep the distance of a Dingyuan, magnetic head and workpiece do not wait apart from excessive or distance, can not give full play to the demagnetization capability of magnetic head, cause demagnetization unclean, the residual magnetism problem that exceeds standard, flexible conveyer belt delivery workpiece Overall Power Consumption is bigger.
The purpose of the utility model is to provide a kind of novel demagnetizer into solving the worn-out end that the demagnetization of flexible conveyer belt delivery workpiece produces, and improves known demagnetizer performance, to improve large size bearing roller workpiece demagnetization effectiveness.
The technical scheme that adopts that achieves the above object is: this demagnetizer that is used for the demagnetization of bearing roller workpiece, comprise frame, can produce the demagnetization magnetic head of alternating magnetic field, and be cemented in decelerator and motor on the frame, it is characterized in that: this demagnetizer has the work stage of rigidity carrying roller workpiece; Also has the thumb wheel mechanism that the bearing roller workpiece is moved on the rigidity work stage, this mechanism comprises the thumb wheel axle by the bearing element supporting, be cemented in the vane type thumb wheel on the thumb wheel axle, on the thumb wheel axle, also be consolidated with to be connected and be used to make thumb wheel axle pivoted pulley with the reducer output shaft machine driving, or sprocket wheel, or gear; Has the groove structure so that the thumb wheel blade rotates on the said rigidity carrying roller workpiece work stage in groove.
Fig. 1 is the organigram of this demagnetizer.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is that the A-A of Fig. 1 is to cutaway view.
Fig. 4 is demagnetization head structure schematic diagram.
The embodiment that provides below in conjunction with accompanying drawing further describes.Referring to accompanying drawing, this demagnetizer includes frame (1), work stage (2), the side plate (3) of work stage (2), side plate (4), be cemented in the magnetic head (5) on side plate (3) or (4) respectively, magnetic head (6), be fixed on motor (7) and decelerator (8) on the frame (1), also include thumb wheel mechanism, there is the support of bearing (9) (10) that is fixed on the support (1) in this mechanism, and by the thumb wheel axle (13) of bearing (11) (12) rolling bearing, be fixed with vane type thumb wheel (14) on the thumb wheel axle (13), also be fixed with belt pulley (15) on the thumb wheel axle (13), belt pulley (15) connects and composes belt drive unit by fixed small belt pulley (17) belt of the belt (16) and the output axle head of decelerator (8).
The concrete structure of the magnetic head that provides among the figure (5) (6) is seen Fig. 4, its structure and operation principle are known technology, no longer superfluous stating, it can select electromagnetic type magnetic head shown in Figure 4 for use, it comprises iron core (18) and hot-wire coil (19), be separately fixed on side plate (4) or (3) by support (20) and (21), coil (19) can be selected straight warp
1.8mm total length is the coil of 2508mm, iron core can be selected the tin plate material for use.It is " 932 19042.1 " that certain magnetic head also can be selected application number for use, and name is called the electric permanent magnetic rotating disk described in " electric permanent magnetic rotating disk " application documents.
Motor among the figure (7) selects for use the 1000 right commercially available motors that turn left then can.Decelerator (8) selects for use the commercially available prod of 63:1 speed ratio to get final product, and work stage among the figure (2) can select for use the thick bakelite plate of 10mm to make, and the centre has groove so that the thumb wheel blade moves in groove.This work stage (2) table top can be made into relative horizontal plane and has slope, so that workpiece moves ahead.Work stage (2) is located also to have two side plates (3) (4) and is fixed on the frame (1) by screw (22) nut (23) and pad (24) respectively, also has the groove structure on the side plate (3) (4) so that two movable being connected on the frame (1) of side plate, with the distance of distance between the accent biside plate that is the relative roller workpiece of adjustment demagnetization magnetic head, can be adjusted definite according to bearing and roller workpiece size size.
Only provided belt pulley (15) among the figure; the belt drive unit that belt (16), small belt pulley (17) constitute; certainly constitute transmission device for reaching thumb wheel (13) to be rotated also can select for use, state because of it is that common Machine Design is no longer superfluous as type of belt drive such as sprocket wheel, gears.
This demagnetizer course of work is as described below: produce alternating magnetic field when demagnetization magnetic head (5) and (6) energising work, will be by demagnetization bearing roller workpiece (25), deliver to the work stage table top from work stage (2) slope eminence end, when motor (7) work rotates thumb wheel axle (13) and the work stage of slowly rolling out in the workpiece platform trough after making it to advance in order at the uniform velocity by the magnetic head (5) (6) that demagnetizes through belt transmission through decelerator (8) again, workpiece is by behind the alternating magnetic field, make the workpiece demagnetization, reach the demagnetization purpose.
The demagnetizer major technique feature that the utility model provides is in the demagnetization process, work stage with rigidity carrying roller workpiece, adding that thumb wheel mechanism gets for flexible belt transmits by demagnetization workpiece mode, solved because the belt conveying work pieces is unclean because of the workpiece demagnetization that change in flexibility causes, residual magnetism exceeds standard, the problem that Overall Power Consumption is big.
