It is believed that the invention can be more deeply and specifically understood as follows: As shown in the second to fourth figures, when the spindle head 2 of the present invention stops instantaneously during high-speed travel, the weight of the weight 30 will be derived from its own weight - the mussel force in the original traveling direction and the chain 2 2 releases itself. The elastic storage position stored in the extension deformation is 'this time'. The elastic damping device of the balance weight damping device 4 为 absorbs the inertial force and the elastic potential energy to release the vibration energy of the derivative weight block 3 〇 bounce Therefore, the balance weight damping device 40 can relatively reduce, relax and consume the inertial force caused by the instantaneous stop of the weight 3 and the elastic potential effect of the chain 2 2 relative to the elastic load buffer of the 1302485. The vibration derived from the resonance effect of the spindle head 21 is relatively reduced, so that the axial vibration is less likely to occur when the cutter shaft 21 is cut, and the corrugation is less likely to occur on the machined surface, which can effectively improve the cutting. Work quality. Please refer to the fifth and sixth figures. The present invention provides another embodiment of the balance weight damping system of the machine tool. The main structure is the same as that of the previous embodiment, and therefore, the weight is not described again. The block 3 is a mass damper, and mainly comprises a body 3 1 and a predetermined number of mass damping blocks 32. The body 3 1 is recessed with an accommodating space 3 1 1 . The two sides of the space 3 1 1 are equidistantly parallel and convexly provided with a number of ribs 3 1 2 '. The accommodating space 3 1 1 is relatively accommodating the mass damping blocks 3 2; α , . The damper block 3 2 in the interior of the sea is a hollow cavity 3 2 1 , and the groove 3 2 1 is provided with an azimuth spacer plate 3 2 2 in the horizontal and vertical intervals, so that the cavity 3 is 2 1 may be equally divided into predetermined intervals, and the container 3 2 1 is filled with a predetermined mass of particle damping 3 2 3 , which is an irregular shape of iron sand. , which is also composed of steel sand with a heavier specific gravity such as steel sand, lead sand, copper sand, etc., = equal particle damping 3 2 3 is filled in the tank 3 2 1 and a predetermined gap is reserved The mass damping block 3 2 is disposed in a receiving space 3丄i of the body 3 1 and is placed in the receiving space 3丄i of the body 3 1 . The field side spindle head 21 stops instantaneously during high speed travel. When the mass damping 2 3 2 3 ^ 1302485 generates a jump in the damping block 3 2 ' at this time, the height of the jump varies with time due to the weight of the particle damping 3 2 3 , and the particle damping 3 2 3 friction between each other' can relatively eliminate the inertial force generated by the weight. Further, the features of the present invention and the achievable expected effects thereof are as follows: • The balance weight damping system of the machine tool of the present invention, the elastic damper of the balance weight damping device can relatively reduce the weight The vibration generated by the inertial force derived from the emergency stop can improve the processing quality of the spindle head under the same cutting conditions, and can enhance the market competitiveness of the machine tool. 2 The balance weight damping system of the machine tool of the present invention can adjust the elastic damper according to the required elastic value and damping value, and can increase the versatility of the elastic damper. 3. The balance weight damping system of the machine tool of the present invention, the weight of the weight can be replaced by a mass damping '. The mass damper not only has the weight of the weight, but also the internal friction of the particles. The force can relatively reduce the inertial force of the weight. In summary, the present invention has excellent advancement in the same kind of products, and at the same time, the technical materials of such structures are frequently investigated at home and abroad, and the same structure is not found in the literature 4, The invention has already been called to clarify the patent requirements, and the application is filed according to law.
