Abstract
A sector eccentric block adjustment mechanism for a vibration motor relates to a vibration motor. Exciting force adjustment of is an existing vibration motor complicated. Generally, the vibrating force is adjusted when the vibration motor leaves the factory. If the exciting force is adjusted by users, the problem that left exciting force adjustment and the right exciting force adjustment are not equal often occurs, and the motor is prone to damage with unbalanced forces during work. The sector eccentric block adjustment mechanism for the vibration motor comprises a driving eccentric block and a driven eccentric block which are capable of being directly in sleeve connection with a shaft of the vibration motor. The driving eccentric block or the driven eccentric block is in the shape of a sector, and the driving eccentric block and the driven eccentric block are characterized in that an annular sector exciting force indication board which is fixed on the driving eccentric block through a connection component is arranged between the driving eccentric block and the driven eccentric block. Users can adjust the exciting force by themselves according to requirements and the exciting force adjustment is led to be more convenient and accurate.

The utility model content
The technical assignment of the technical problems to be solved in the utility model and proposition is that the prior art scheme is improved and improved, and a kind of fan-shaped eccentric block adjusting mechanism of vibrating motor is provided, to reach easy to adjust, the purpose accurately of exciting force.For this reason, the utility model is taked following technical scheme.
A kind of fan-shaped eccentric block adjusting mechanism of vibrating motor, comprise the active eccentric block and the driven eccentric block that can be socketed in the vibrating motor rotating shaft, described active eccentric block and driven eccentric block are fan-shaped, it is characterized in that: be provided with the exciting force direction board between described active eccentric block and the driven eccentric block, described exciting force direction board is the fan ring-type, and it is fixed on the active eccentric block by connector.The exciting force direction board is used to show the size of exciting force, sets up the exciting force direction board, and the user regulates voluntarily with reference to the scale on the exciting force direction board as required, and exciting force is easy to adjust, accurate.
As the further of technique scheme improved and replenish, the utility model also comprises following additional technical feature.
Described connector is a rivet, and 3 rivets are fixed on the exciting force direction board near on the active eccentric block of driven eccentric block one side.The exciting force direction board adopts rivet to fix, and is fixing reliable, accurately, and projection is little, is difficult for producing the movement interference with driven eccentric block.
Described active eccentric block and driven eccentric block semicircular in shape, comprise straight flange and circular arc limit, the straight flange middle part outwards convexes to form connecting portion, the junction of connecting portion and straight flange has axis hole to pass rotating shaft, described connecting portion has elastic groove, and the elastic groove cross bolts is to block the eccentric block that only is socketed in the rotating shaft.Initiatively eccentric block is located by key, and relatively initiatively the eccentric block rotation is to adjust exciting force for driven eccentric block, and when the shape of both active eccentric blocks and driven eccentric block was identical in quality, the adjusting range of exciting force was 0～100%.
Described exciting force direction board comprises the direction board matrix, is located at the scale presentation layer on the direction board matrix, and described direction board matrix is formed through a punching press by foil.Direction board is easy to process.The foil material can be selected aluminium alloy for use, and through extrusion molding, for improving its corrosion resistance, its surface can be through electrophoretic process.
The top of described scale presentation layer is covered with the scale protective layer.Cover the scale protective layer on the scale presentation layer, can the scale presentation layer not ground off because of friction between driven eccentric block and the direction board.
Described direction board matrix is semi-annular shape, comprises two straight flanges and two circular arc limits, and wherein a straight flange is provided with the limiting section that can offset with the straight flange of driven eccentric block of evagination.
Direction board matrix one straight flange extends upward outwards turnover 90 degree formation limiting sections of back.
Limiting section is positioned at the direction board matrix straight flange place near the maximum exciting force of expression.Limit the reverse adjustment of driven eccentric block, helped keeping the adjustment unanimity at two ends, the left and right sides.
Rivet head embeds the direction board matrix.Effectively prevent to interfere.
Beneficial effect: set up the exciting force direction board, the user regulates as required voluntarily, and exciting force is easy to adjust, accurate.
