The specific embodiment
On platform 6, be provided with framework 13 as shown in Figure 1, be provided with running roller 14 in the framework 13, motor hanging basket 2 is fixed on the framework 13, be provided with a motor 1 in the motor hanging basket 2,15 of motor drive 4 and running roller drives are provided with driving-belt 3, be the base plate 5 of an inclination between motor 1 and the motor hanging basket base plate 7, motor 1 is arranged on the base plate 5, the left end of base plate 5 is connected on the motor hanging basket base plate 7 by bolster 8, the other end is unsettled, be provided with the gap between base plate 5 and the motor hanging basket base plate 7, be provided with an elastic mechanism in the bottom of motor hanging basket 2, spring shaft 9 upper ends in the elastic mechanism are connected with base plate 5, spring shaft 9 is located at the end of keeping right of base plate 5, and spring shaft 9 passes motor hanging basket base plate 7, and is provided with nut 16 in spring shaft 9 lower ends, fixedly back-up ring 10 and Rubber shock-absorbing pad 12, compression spring 11 is arranged on motor hanging basket base plate 7 and the fixing spring shaft between the back-up ring 10 9, and the two ends up and down of compressing spring 11 respectively are provided with a Rubber shock-absorbing pad 12.
During motor 1 running, because factors such as foozle, spare and accessory parts quality, and the physical principle decision of motor own, can produce certain vibrations and noise inevitably, the sound wave that its vibrations and noise and air produce can make connected framework 13 shake with the active roll 14 that is connected by driving-belt 3 by conduction; Vibration rear motor axle head has fluctuation a little up and down, it is loosening that driving-belt 3 is connected with motor drive 4, driving-belt 3 provides one pulling force by the machine shaft end of 4 pairs of motors 1 of motor drive, base plate 5 right-hand members are connected with motor, base plate 5 left ends are fixed on motor hanging basket base plate 7 by back shaft 8, be with rubber shock-absorbing sleeve on the back shaft 8, base plate 5 right-hand members are pulled upwardly by driving-belt with motor, shape at a tilt angle between base plate 5 and the motor hanging basket base plate 7, the angle of inclination is at 5-30 °, spring shaft 9 has been fixed on the base plate 5, so spring shaft 9 also is pulled upwardly, this moment is because compression spring 11 is to be fixed on motor hanging basket base plate and fixedly between the back-up ring 10, when upwards drawing high, fixedly back-up ring 10 on the spring shaft 9 will compress spring to the extruding of motor hanging basket base plate direction, because the telescopic resilience of compression spring 11 provides one resistance to the spring shaft 9 that rises, the pulling force that this strand resistance and driving-belt 3 provide has slowed down the vibration of motor 1.
The vibration of motor has driven moving up and down of spring shaft, the resistance that then compresses spring has slowed down spring shaft and has moved up, thereby reduced the Oscillation Amplitude influence of motor, the pulling force of this strand resistance and driving-belt provides a kind of equilibrant force for the balance of keeping motor, base plate with the folding up and down of the gap of motor hanging basket base plate, then can cushion part vibration to a certain extent, base plate is a fulcrum with the rubber shock-absorbing sleeve on the bolster under motor oscillating influence, that it is inclined upwardly is unsettled by carrying on the driving-belt tractive for other end end, its stiff end and motor hanging basket base form certain angle, downward pressure by motor and base plate deadweight thereof, and the downward tension force of spring after being compressed, the three is common to form a dynamic equilibrium system, can play damping simultaneously and to the auto-tensioning effect of driving-belt.
Other auxiliary machines of the present utility model, pump all be installed on periphery not with foundation that cutting machine links to each other on, owing to silicon chip is very thin and very high to quality requirement, vibrations slightly will have a strong impact on the quality of section, even section work can't be gone on.Therefore, installing rubber shock-absorbing sleeve, compression spring, Rubber shock-absorbing pad from the nearest electric baseboard of noise source, install the rubber shock-absorbing module additional at motor hanging basket and framework junction, and at the transmission adopted flexible driving band, by these technical measures, to greatly prevent and reduce vibrations that motor rotate to produce and noise adverse effect to chipping qualities, make the cutting function steadily, long period work smoothly goes down.Driving-belt relaxes through turning round after a while, and the compression stress of compressing the spring pretension this moment discharges, and makes driving-belt be in the duty of certain rate of tension all the time, utilizes this cover elastic mechanism that driving-belt has been played the auto-tensioning effect.
