Description
Technical field
The utility model relates to a kind of arrangements for speed regulation of electric tool, particularly a kind of automatic speed governing device of saw blade type electric tool.
Background technology
At present, saw blade type electric tools such as electric circular saw, bench saw, bias cutter generally have only a kind of rotating speed when cutting, also can only cut a kind of material preferably, for example high rotating speed can cut timber, but it is just bad to cut the steel effect with same rotating speed, and the too high saw blade heating of rotating speed is fast, fragile; But, but can not cut materials such as timber preferably if the slow-speed of revolution just can have effect preferably to the steel cutting processing.Because cutting tool can not cut the material of unlike material, so the user need be equipped with the cutting tool of many different purposes, and this not only increases the cost of procuring equipment, and increases management cost, takies more place, and brings inconvenience to the user.Therefore, how to develop and a kind ofly can be used for high-speed cutting, can be used for the multi function cutting tool of low speed cutting again, become an emphasis research topic of electric tool exploitation; For this reason, many manufacturers and knowledgeable people research and develop at the problems referred to above, but do not have better products to emerge so far as yet.
Summary of the invention
For overcoming the problem of above-mentioned existence, the purpose of this utility model provide a kind of simple and compact for structure, easy to install, can guarantee that the saw blade type electric tool has two kinds of different cutting speeds to realize Circular saw blade electric power tool automatic speed controller to the different materials cutting.
The technical scheme that its technical problem that solves the utility model adopts, it comprises body, saw blade support plate and saw blade pressing plate, the output shaft of described body is provided with shaft retaining ring, on the output shaft of shaft retaining ring inboard, be provided with conversion axle sleeve, thrust bearing, driving lever, spring successively, saw blade support plate and saw blade pressing plate are arranged on the output shaft in the shaft retaining ring outside, saw blade is arranged between saw blade support plate and the saw blade pressing plate and by the locking screw and fixes, and driving lever is connected with control device.
As further characteristics of the present utility model, described control device comprises rocking bar, electric function converter, and rocking bar is hinged on the body, and the electric function converter is fixed on the body, one end of rocking bar is connected on the driving lever, and the microswitch in the other end and the electric function converter cooperates.
As further characteristics of the present utility model, the center of described saw blade support plate is provided with round platform A and the round platform B that protrudes to both sides, and round platform B matches with the inner chamber of conversion axle sleeve.
As further characteristics of the present utility model, described round platform A diameter is greater than the diameter of round platform B, and the intracavity diameter of conversion axle sleeve is less than the diameter of round platform A, and greater than the diameter of round platform B.
After adopting said structure, when adopting the saw blade of cutting different materials, because the size difference of saw blade installing hole, bearing-surface that can corresponding change saw blade support plate, by of the different cooperations of this bearing-surface with the conversion axle sleeve, drive thrust bearing, driving lever and spring and do corresponding moving, prop up action by driving lever by the microswitch in the rocking bar control electric function converter then, control the automatic adjusting of saw blade type electric tool motor speed at last by the electric function converter.Can not be thereby solve existing saw blade type electric tool with the cutting of machine realization to different materials; Advantage such as motor automatic speed regulation when having the saw blade simple and reasonable, easy to use, that the cutting different materials is installed.

The specific embodiment
Illustrated in figures 1 and 2, specific embodiments for a kind of Circular saw blade electric power tool automatic speed controller of the utility model, it comprises body 1, saw blade support plate 7 and saw blade pressing plate 10, the output shaft 2 of described body is provided with shaft retaining ring 3, on the output shaft 2 of shaft retaining ring 3 inboards, be provided with conversion axle sleeve 6 successively, thrust bearing 5, driving lever 11, spring 4, conversion axle sleeve 6 and thrust bearing 5 are back-to-back, also can increase cavity and cover thrust bearing 5, saw blade support plate 7 and saw blade pressing plate 10 are arranged on the output shaft 2 in shaft retaining ring 3 outsides, saw blade 8 is arranged between saw blade support plate 7 and the saw blade pressing plate 10 and by locking screw 9 and fixes, and driving lever 11 is connected with control device; Described control device comprises rocking bar 12, electric function converter 13, rocking bar 12 is hinged on the body 1, electric function converter 3 is fixed on the body 1, and an end of rocking bar 12 is connected on the driving lever 11, and the microswitch in the other end and the electric function converter 13 cooperates; The center of described saw blade support plate 7 is provided with round platform A and the round platform B that protrudes to both sides, and round platform B matches with the inner chamber of conversion axle sleeve 6; Described round platform A diameter is greater than the diameter of round platform B, and the intracavity diameter of conversion axle sleeve 6 is less than the diameter of round platform A, and greater than the diameter of round platform B.
During rated speed, saw blade 8 is installed on the round platform A between saw blade support plate 7 and the saw blade pressing plate 10 and by locking screw 9 and fixes, round platform B is against the outside of shaft retaining ring 3, under the thrust of spring 4, conversion axle sleeve 6, thrust bearing 5, driving lever 11 are pressed on together, the inner chamber of conversion axle sleeve 6 is against the inboard of shaft retaining ring 3, and round platform B cooperates with the inner chamber of conversion axle sleeve 6, but saw blade support plate 7 does not contact with conversion axle sleeve 6; During operate as normal, conversion axle sleeve 6 rotates with speed with output shaft 2, because the effect of thrust bearing 5, driving lever 11 is not with output shaft 2 rotations, rocking bar 12 is without any action and be in original state, microswitch in the electric function converter 13 is in off position, and electric function converter 13 is not worked, and motor is worked under the rated speed state.
When the cutting different materials, need the different saw blade 8 of transposing, because used saw blade 8 differences, its endoporus is in different size, needs saw blade support plate 7 oppositely to be installed the structural representation when being illustrated in figure 3 as second rotating speed; At this moment, the round platform B that saw blade 8 is installed between saw blade support plate 7 and the saw blade pressing plate 10 goes up and is fixed by locking screw 9, round platform A is against the outside of shaft retaining ring 3, because the diameter of round platform A is greater than the intracavity diameter of conversion axle sleeve 6, therefore round platform A can't cooperate with the inner chamber of conversion axle sleeve 6, the end face of round platform A presses the outer face of changing axle sleeve 6, conversion axle sleeve 6 promotes driving levers 11 by thrust bearing 5 and moves inward and compress spring 4, the microswitch work that driving lever 11 drives in the electric function converter 13 by rocking bar 12, electric function converter 3 work back control motors move by second speed, thereby realize the purpose of this utility model; Because the effect of thrust bearing 5, conversion axle sleeve 6 and output shaft 2 speed rotation together, 11 of driving levers produce displacement not with output shaft 2 rotations.
