Beneficial effect is that headstock with shock-absorbing function solve from the vibration source, will produce the vibration most obvious, carry out shock attenuation processing to the headstock that the lathe precision influences the biggest, unite two into one the shock absorption nature and the headstock frame of reason stone material, guaranteed the intensity of headstock body through the rigidity of headstock box self, thereby the good shock absorption effect of reason stone material has reduced the influence of main shaft vibrations at the in-process of processing to mechanical precision.
Description
Technical Field
The utility model belongs to machinery shock attenuation field especially relates to a headstock with shock-absorbing function.
Background
In recent years, with the development of automatic machining technology, the application of electric spindles/mechanical spindles to machine tools or automatic equipment is expanding. The use of artificial marble beds on machine beds is also becoming more common. The artificial marble has the advantages of high damping coefficient, low thermal conductivity 1/20 of cast iron and the like. The main shaft can generate vibration in the process of processing a workpiece, and the vibration is directly transmitted to the machine tool, so that the integral precision of the machine tool is unstable.
The traditional main shaft box body can only absorb shock through single materials such as cast iron materials or alloy materials and carbon fibers, and measures for influencing the precision of the machine tool by vibration generated during the machining of the main shaft can only absorb a vibration source by means of the single materials through changing the material of the machine tool body. The traditional damping mode and the transmission damping mode are all to improve the vibration in the modes of changing the structure of a machine body or changing the material of the machine body, changing the layout of a workpiece spindle box and the like.
The problem that the vibration of the machine tool always becomes a troubling designer is solved.
SUMMERY OF THE UTILITY MODEL
In order to solve and reduce the main shaft in the course of working, because the unstable problem that produces the vibration of lathe bed precision that the vibration leads to, the utility model provides a headstock with shock-absorbing function, this headstock unites two into one the shock absorption nature of reason stone material and headstock frame, has guaranteed the intensity of headstock body through the rigidity of headstock box self, thereby the good shock absorption effect of reason stone material has reduced the influence of main shaft vibrations at the in-process of processing to mechanical precision.
The technical scheme is as follows:
the utility model provides a headstock with shock-absorbing function, includes: the main shaft box comprises a main shaft box body and a mineral resin layer, wherein the mineral resin layer is arranged below the main shaft box body.
Furthermore, a cavity is formed in the bottom of the main spindle box body, and the mineral resin layer is arranged in the cavity.
Further, the device also comprises a spindle box fixing sliding table and screws, wherein a plurality of nut holes are formed in the mineral resin layer, and the spindle box body is connected with the spindle box fixing sliding table through the screws.
Furthermore, a through hole is arranged on the spindle box body 1.
Furthermore, the cross section of the through hole is circular, and the diameter of the circle A of the cross section of the two ends of the through hole is larger than that of the circle B of the cross section of the middle of the through hole.
Further, the cross section of the mineral resin layer is rectangular.
Further, the mineral resin layer is replaced by a duplicating glue layer.
The utility model has the advantages that:
headstock with shock-absorbing function solve from the vibration source, will produce the vibration most obviously, carry out shock attenuation to the biggest headstock of lathe precision influence and handle, unite two into one the shock absorption nature of reason stone material and headstock frame, guaranteed the intensity of the headstock body through the rigidity of headstock box self, thereby the good shock absorption effect of reason stone material has reduced the influence of main shaft vibrations to mechanical precision at the in-process of processing.
