Description
Technical field
The utility model relates to a kind of arrangements for speed regulation, is specifically related to a kind of sanding machine arrangements for speed regulation.
Background technology
Sanding machine is one of indispensable electric tool in machining, and its application scenario is more, but various occasion requires to be not quite similar to the rotating speed of its work.At present, sanding machine of the prior art mostly is the constant speed sanding machine or adopts infinite variable speed sanding machine, and this series products has played good effect in some various occasions, but under some special various occasion, can be helpless.During such as a plurality of same parts of processing, require its burnishing surface in full accord, this just needs substantially on all four rotating speed, and the rotating speed when infinite variable speed sanding machine is difficult to be adjusted into a plurality of same parts of processing is in full accord, brings impact to production.
The utility model content
The purpose of this utility model is exactly the defective that exists for prior art, and a kind of sanding machine arrangements for speed regulation are provided.
Its technical scheme is: comprise the first electric capacity, the second electric capacity, the 3rd electric capacity, the 4th electric capacity, resistance, the first switch, second switch, the 3rd switch, the 4th switch, the 5th switch and the 6th switch.One end of described the first switch is connected with an end of second switch and an end of the second electric capacity by the first electric capacity, the other end of the second electric capacity is connected with an end of the 3rd switch and an end of the 3rd electric capacity, the other end of the 3rd electric capacity is connected with an end of the 4th switch and an end of the 4th electric capacity, the other end of the 4th electric capacity is connected with an end of the 5th switch and an end of resistance, and the other end of resistance is the first control end; One end of the 6th switch is unsettled, and the other end of the other end of the other end of the first switch, the other end of second switch, the 3rd switch, the other end of the 4th switch, the 5th switch and the other end of the 6th switch connect and be connected with the second control end.
Wherein, described the first switch, second switch, the 3rd switch, the 4th switch, the 5th switch, the 6th switch are the interlocking-type key switch.The resistance of described resistance is 0.1-1 Ω.The capacity of described the first electric capacity, the second electric capacity, the 3rd electric capacity and the 4th electric capacity is 1-10uf.
The utility model has following advantage compared with prior art: simple in structure, easy to use, many grades of manual constant speed of energy help to improve the crudy in production.
Description of drawings
Fig. 1 is the circuit theory diagrams of a kind of embodiment of the utility model.
The specific embodiment
With reference to Fig. 1, a kind of sanding machine arrangements for speed regulation comprise the first capacitor C 1, the second capacitor C 2, the 3rd capacitor C 3, the 4th capacitor C 4, resistance R, the first K switch 1, second switch K2, the 3rd K switch 3, the 4th K switch 4, the 5th K switch 5 and the 6th K switch 0.One end of described the first K switch 1 is connected with the end of second switch K2 and an end of the second capacitor C 2 by the first capacitor C 1, the other end of the second capacitor C 2 is connected with an end of the 3rd K switch 3 and an end of the 3rd capacitor C 3, the other end of the 3rd capacitor C 3 is connected with an end of the 4th K switch 4 and an end of the 4th capacitor C 4, the other end of the 4th capacitor C 4 is connected with an end of the 5th K switch 5 and an end of resistance R, and the other end of resistance R is the first control end A; One end of the 6th K switch 0 is unsettled, and the other end of the other end of the other end of the other end of the first K switch 1, second switch K2, the other end of the 3rd K switch 3, the 4th K switch 4, the other end of the 5th K switch 5 and the 6th K switch 6 connects and is connected with the second control end B.Wherein, described the first K switch 1, second switch K2, the 3rd K switch 3, the 4th K switch 4, the 5th K switch 5, the 6th K switch 6 are the interlocking-type key switch.The resistance of described resistance R is 0.1-1 Ω.The capacity of described the first capacitor C 1, the second capacitor C 2, the 3rd capacitor C 3 and the 4th capacitor C 4 is 1-10uf.
During use, the first control end A and the second control end B two ends are connected in series on a power line of sanding machine and get final product.When pressing the 6th K switch 6, the sanding machine stall, when pressing successively the first K switch 1, second switch K2, the 3rd K switch 3, the 4th K switch 4, the 5th K switch 5, the rotating speed of sanding machine improves step by step.
