On the premise of, the cost simultaneously that is designed beautifully is lower；
5, cabinet of the present invention carries out many-sided Design of Reinforcement, fully gets rid of the probability of deformation, it is to avoid go out
Now mould shell speed regulator at present on the market and cause the Hall unit on rocking arm upper magnetic steel and circuit board due to the deformation of plastics
The relative position change of part and cause the inaccurate problem of output voltage values.
Accompanying drawing illustrates:
Fig. 1 is the front view of the present invention；
Fig. 2 is the schematic perspective view of the present invention；
Fig. 3 is the rearview of the present invention；
Fig. 4 is the schematic diagram of the pcb board of the present invention.
Detailed description of the invention:
With specific embodiment, the invention will be further described below, sees Fig. 14:
The industrial sewing machine speed regulator of a kind of low-cost and high-performance, including housing 1, rocking arm 2, housing 1 is for moulding
Material housing, one end of rocking arm 2 is connected on housing 1 by pin 3, and the outer surface at pin 3 is provided with
Annular knurl.The baseplane of housing 1 is stretched out in one end of pin 3, and is fixed by jump ring 10, jump ring 10 with
Pad 11 is set between housing 1.Rocking arm 2 can swing around pin 3, is provided with magnet steel 4 on rocking arm 2,
Magnet steel 4 swings with rocking arm 2, is provided with hall circuitboard 5, on hall circuitboard 5 on housing 1
Magnet steel 4 on Hall element perception rocking arm 2 causes the change output of induction point magnetic field intensity accordingly because of swing
Analogue signal, and this signal is passed to master control borad, master control borad completes the control to motor speed.
The rocking arm 2 of the present invention and magnet steel 4 integration coordinate, and are determined initially by the position of hall circuitboard 5
State, it is to avoid when causing long such as existing speed regulator rocking arm by the assembling mode of mechanical part mounting magnetic steel
Between use magnet steel change in location that the problem that resetting voltage value is inaccurate occurs.
In speed regulator production technology, the regulation of original state is by the fixing hole on hall circuitboard 5 and housing
The relative position fixing post on 1 realizes.The regulation of original state for convenience, at hall circuitboard 5
Being provided with two installing holes at the diagonal angle of pcb board 6, an installing hole is standard installation hole 7, and another is installed
Hole is arc installing hole 8.
Concrete installation process is as follows:
First fix the standard installation hole 7 of hall circuitboard 5, it is ensured that the position-adjustable of hall circuitboard 5
Die down.This standard installation hole 7 and screw mate the most completely, play spacing effect, it is ensured that whole Hall
On circuit board 5, the adjustment of Hall element front and back position fully relies on the position that at arc installing hole 8, screw is fixing
Put, will not move forward and backward because of hall circuitboard 5 stress during a fixing other screw.Next with solid
Rotary Hall circuit board 5 centered by the standard installation hole 7 reserved is until the output voltage values of hall circuitboard 5
Within the scope of regulation, with the screw at suitable torque lock death jail arc installing hole 8, the most complete
The screw of locked standard installation hole 7.So efficiently solve aborning owing to causing suddenly when screw is fixed
Your circuit board 5 position is easily moved thus is caused the inefficient problem of the regulation of initial state voltage value.
For avoiding the occurrence of the accident of sewing machine pedal ground connection, it is ensured that the circuit board (such as thunderbolt) in the presence of a harsh environment
Capacity of resisting disturbance, described magnet steel 4 is arranged in magnet steel clamshell 9, and magnet steel clamshell 9 is fixed on rocking arm 2,
Magnet steel leads to 4 magnet steel clamshells 9 excessively and insulate with rocking arm 2.
In order to fully get rid of the probability of housing 1 deformation, it is to avoid occur at present on the market due to plastic casing
Deformation causes rocking arm upper magnetic steel position change relative with the Hall element on hall circuitboard to cause output electricity
The problem that pressure value is inaccurate, the present invention is provided with reinforcing rib structure on the baseplane of the housing 1 of pin 3 surrounding.
Specifically being provided with the cylinder projection 12 of band mesopore on housing 1 baseplane at pin 3 place, cylinder is protruding
12 are outside equipped with the reinforcement 13 that circumferentially distributed emitting shape is arranged.
The operation principle of the present invention:
The fixing base plate 13 of the present invention is fixed by screws on sewing machine table, and rocking arm 2 is by pull bar and seam
Machine pedal of threading connects.Along with rocking arm 2 moves up and down centered by pin 3, on hall circuitboard 5
Hall element perception rocking arm 2 upper magnetic steel 4 causes the change of induction point magnetic field intensity due to swing, exports phase
Answer analogue signal, pass to master control borad and complete the control to motor speed.In structure designs, take into full account U.S.
The property seen, fastness, carry out force analysis, it is to avoid mechanically stressed dead angle to whole speed regulator.
Above-described embodiment is only one of presently preferred embodiments of the present invention, not limits the present invention's with this
Practical range, therefore: the equivalence change that all shapes under this invention, structure, principle are done, all should
Within being covered by protection scope of the present invention.
