Abstract

The utility model discloses a novel low-speed diamond cutter rotating shaft moving part, which belongs to the field of material processing equipment, and comprises a shaft, set screws, a front clamp plate, a saw blade, a rear clamp plate and a big screw, because a shaft shoulder which is matched with the saw blade is a conical surface, a cutter can use saw blades with different shaft hole diameters, and guarantees the shaft and the saw blades to be strictly coaxially arranged simultaneously. The front clamp plate and a shaft body are connected through threads, and the relative positions of the front clamp plate and the shaft body can be continuously adjusted. When the position of the front clamp plate is proper, the front clamp plate is fixed through the two set screws which are symmetrically distributed. The novel low-speed diamond cutter rotating shaft moving part prevents vibration caused by eccentric error, guarantees continuity during the cutting process, improves cutting efficiency, prolongs life of the cutter, and eliminates running noise.

Description

A kind of rotating shaft dynamic component of low-speed diamond cutting machine

Technical field

The utility model relates to material processing plant field, is specifically related to a kind of rotating shaft dynamic component of low-speed diamond cutting machine.

Background technology

The moving part of rotating shaft of now general low-speed diamond cutting machine is made up of axle, front plate, saw blade, rear plate and large screw.The diameter of axle of the axle body part coordinating with saw blade is fixed, and the aperture axis of the saw blade that therefore cutting machine of certain model uses, also for definite value, causes cutting machine and saw blade poor compatibility.On the other hand, because the cooperation of axle and saw blade is matched in clearance, make axle and the saw blade can not be strictly coaxial in the time that reality coordinates, between them, exist the centering error with magnitudes such as this gaps.When rotated, saw blade is equivalent to an eccentric wheel, causes its blade not to be stably with contacting of workpiece in the process of cutting, but vibration, when frequency is higher, even beat.Therefore, often there is the accident that saw blade and workpiece are killed, sometimes even saw blade burst apart, thus whole cutting process must someone monitor, cutting process is difficult to disposable completing.In addition, the noise that generation of vibration is very large, has worsened working environment.What is more important, this vibration or the meeting of beating cause damage to whole diced system, shorten its service life.

Summary of the invention

In order to overcome several problems of low-speed diamond cutting machine mentioned in above-mentioned technical background, be that poor compatibility, controllability are low, noise is large, the life-span is short, the utility model has designed a kind of novel cutting machine rotating shaft dynamic component, clamping plate are also done to corresponding improvement, can solve well these problems.

The utility model provides a kind of low-speed diamond cutting machine rotating shaft dynamic component, this rotating shaft dynamic component comprises axle, holding screw, front plate, saw blade, rear plate and large screw, the described shaft shoulder is taper surface, the span of the angle theta of itself and axis is: 90 ° of < θ <180 °, the mating surface of saw blade and axle taper surface for this reason.

Further, the span of the angle theta of the shaft shoulder and axis is: 120 ° of < θ <150 °.

Further, axle is connected by external screw thread with front plate, and the relative position of front plate and axle can regulate continuously by this screw thread rotation; In the time that front plate is adjusted to appropriate location, utilize two symmetrical holding screws that it is locked.

The principles of science of the present utility model is:

The part that the utility model axle body coordinates with saw blade---the shaft shoulder is taper surface, the saw blade with disalignment aperture can be coordinated with same axis, and the two is all the time in appropriate cooperation.Although saw blade is that line contacts with axle in theory, but the position of front plate is by regulating continuously with being threaded of axle, itself and rear plate be saw blade is fastening and location from the side, make saw blade keep good rigidity, can carry a certain amount of vertical and horizontal load, guarantee the pressure contact of saw blade blade and workpiece.In addition, because cooperation is appropriate, so saw blade and axle are concentrics, in circumgyration incision process, there will not be the high vibration that similar centering error causes or beat, having guaranteed the stationarity of cut state.Moreover this stationarity has been avoided killing of saw blade and workpiece, thereby guarantee the continuity of cutting process.What is more important, it can avoid bursting apart of saw blade effectively, has greatly eliminated the infringement of vibration to this cutting machine simultaneously, has extended the service life of whole system, and has reduced noise, has optimized working environment.

Compared with prior art, technique effect of the present utility model is:

1, the utility model has been avoided the vibration that centering error causes, has guaranteed the continuity of cutting process, has improved cutting efficiency, has extended the life-span of cutting machine, and has eliminated operation noise;

2, the diamond saw blade that the cutting machine of same model can compatible many kinds of specification.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is further described.

As shown in Figure 2, the rotating shaft dynamic component of now general low-speed diamond cutting machine mainly comprises axle 1, front plate 2, diamond saw blade 3, rear plate 4, large screw 5.

As shown in Figure 8, in the utility model, the rotating shaft dynamic component of low-speed diamond cutting machine mainly comprises trip bolt 7, front plate 2, axle 1, diamond saw blade 3, rear plate 4, large screw 5.

As shown in Figure 9, the conical surface shaft shoulder 6 is θ with the angle of axis, and there are 90 ° of < θ <180 °, in reality, can get 120 ° of < θ <150 °, the saw blade of aperture axis within the scope of d～D can use on same cutting machine like this.Front plate 2 is connected for external screw thread 8 with axle 1, and relative position can regulate continuously, when location-appropriate, fixing by two holding screws 7.
