Abstract
The utility model relates to an automatic tension-regulating mechanism of saw blades, and more specifically, the utility model relates to a belt wheel spring device for damping vibration. The utility model is composed of a belt wheel, a fixing block, a sliding sleeve, a guide sleeve, a spring, pins and an upper cross beam; the sliding sleeve and the guide sleeve are inserted into the center of the upper cross beam and the spring is fixed in the sliding sleeve by pin; the fixing block is coaxially connected with the belt wheel, and the spring can achieve the effect of damping vibration when the belt wheel works; the belt wheel has the advantages of good guiding performance, flexible action and low cost; saw blades are uniform in stress, which effectively extends the service life of the saw blades.
Description
The utility model relates to a kind of automatic adjusting saw blade tension mechanism, and it is a kind of belt wheel spring damper.
Do not having on the band saw of spring damper, driven pulley is for adjusting wheel, when saw blade is adjusted to a certain extent, two belt wheel position relative fixed are constant, because belt wheel and saw blade are subjected to the influence of machining accuracy, belt wheel can produce circular runout when rotating at a high speed, and this must make saw blade produce the stretching in cycle, saw blade is beated with belt wheel, produce vibration and very fast generation fatigue damage.In addition again by the influence of cutting external force size, the saw blade power effect that directly is hit to blade life is reduced greatly, and descends cutting accuracy.And common belt wheel damper mechanism is made up of devices such as belt wheel, fork, back shaft, spring, regulating handles,, on belt wheel, this mechanism structure complexity, need certain space, cost height and can cause indirect vibration and noise with the lever principle indirectly-acting.
It is a kind of simple and compact for structure that the purpose of this utility model is to provide, and leads, and is active in one's movements, cost is low, need not the artificial belt wheel spring damper of adjusting.
Above-mentioned purpose realizes by following scheme: a kind of belt wheel spring damper is to be made of belt wheel, fixed block, sliding sleeve, guide pin bushing, spring, pin, entablature; Be shaped on the perforation of vertical jack and level in the entablature center, guide pin bushing also is shaped on perforation, and the sliding sleeve bottom is shaped on the location slotted hole; Spring is packed in the sliding sleeve, its sliding sleeve is contained in the guide pin bushing, and guide pin bushing inserts the central hole of entablature, and pin passes entablature perforation, guide pin bushing perforation and locatees slotted hole by sliding sleeve and is positioned at the spring bottom, fixed block is coaxial the connection with belt wheel, and its fixed block is fixed on sliding sleeve top.
Characteristics of the present utility model are: this belt wheel spring damper acts directly on the belt wheel, and is simple and compact for structure, leads, and is active in one's movements, and cost is low; This device need not artificial adjustment, has avoided that the too tight or too loose situation of saw blade takes place after the artificial adjustment, and it can make saw blade keep being in the vibration damping state under the more constant situation, and its saw blade is stressed evenly, the service life of having improved saw blade greatly.
Below in conjunction with accompanying drawing in detail embodiment of the present utility model is described in detail:
Accompanying drawing 1, belt wheel spring damper structural representation;
Among the figure: 1 belt wheel, 2 fixed blocks, 3 sliding sleeves, 4 guide pin bushings, 5 springs, 6 pins, 7 entablatures, 8.
As shown, open the perforation of a vertical jack and a level in entablature 7 centers, open one and entablature 7 corresponding levels perforation in guide pin bushing 4 bottoms, make a location slotted hole in sliding sleeve 3 bottoms, then sliding sleeve 3 is put into guide pin bushing 4, spring 5 is put into sliding sleeve 3, again guide pin bushing 4 is inserted in the entablature 7, with each perforation and location slotted hole alignment, with entablature 7, guide pin bushing 4 and sliding sleeve 3 lockings, the worker is squeezed on the pin 6 spring 5 with pin 6 then; After fixed block 2 is fixed on slideway 3 tops, use axle 8 with fixed block 2 and 1 coaxial connection of belt wheel.After belt wheel 1 work, its fixed block 2 can be with the vibration of spring 5 to reach damping effect.
Claims (1)
1, a kind of belt wheel spring damper is characterized in that it is to be made of belt wheel, fixed block, sliding sleeve, guide pin bushing, spring, pin, entablature; Be shaped on the perforation of vertical jack and level in the entablature center, guide pin bushing also is shaped on perforation, and the sliding sleeve bottom is shaped on the location slotted hole; Spring is packed in the sliding sleeve, its sliding sleeve is contained in the guide pin bushing, and guide pin bushing inserts the central hole of entablature, and pin passes entablature perforation, guide pin bushing perforation and locatees slotted hole by sliding sleeve and is through at the spring bottom, fixed block is coaxial the connection with belt wheel, and its fixed block is fixed on sliding sleeve top.
