Mechanical grinding central spindle mechanism

Abstract

The invention relates to a mechanical grinding central spindle mechanism, which is characterized in that a central spindle is connected onto a connecting body; an oilstone and a rotating steel ball are arranged in inner cavities of the connecting body and the central spindle; the oilstone and the rotating steel ball are fixed through adjusting screws; a rotating body bearing and a flexible spring are arranged on the central spindle on the front end of the rotating steel ball; and the flexible spring is fixed by a spring collar. The spring collar and axial fixing structures of the adjusting screws and the rotating steel ball which are positioned on the central spindle are adopted, so that an oil seat can be stretched out under the driving of a conical body of the central spindle so as to be adapted to the size and the grinding degree of a needed workpiece and adjusted to be a corresponding hole and grinding accuracy, and the aim of the mechanism is achieved. The mechanism has the advantages of simple structure, good general performances, convenience in adjustment, and high production efficiency.

Description

technical field [0001] The invention relates to a grinding shaft core mechanism, in particular to a mechanical grinding shaft core mechanism, which belongs to the technical field of mechanical manufacturing. Background technique [0002] At present, in the field of processing and manufacturing, it is necessary to install an independent mechanical grinding shaft core mechanism in the mechanical equipment to drive the grinding head to perform the grinding process. Since the size of the grinding workpiece is different from the required grinding program, therefore, The existing mechanical grinding shaft core mechanism has the defects of complex structure, poor versatility, troublesome adjustment and low production efficiency. Contents of the invention [0003] The object of the present invention is to provide a mechanical grinding shaft core mechanism with simple structure, good general performance, convenient adjustment and high production efficiency, so as to overcome the ab...

Problems solved by technology

[0005] Beneficial effects: Since the present invention adopts the axial fixed structure of the spring retaining ring, the adjusting screw and the rotating steel ball positioned on the shaft core, the oil seat protrudes under the push of the shaft core cone to meet the size of the required workpiece and the degree of grinding, adjust to the corresponding holes and the precision of grinding, and achieve the purpose of the present invention. This mechanism has the advantages of simple structure, good general performance, convenient adjustment and high production efficiency, and achieves the purpose of the present invention. Effective It overcomes the defects of complex structure, poor versatility, troublesome adjustment and low production efficiency existing in the existing mechanical grinding shaft core
