Abstract

The utility model discloses a pneumatic high-speed universal grinding machine. The utility model is characterized in that the side face of a cross slide (1) is hinged with a revolving grinding wheel frame which is formed by successively from bottom to top connecting a rotary mechanism, a manual radius adjusting mechanism, a high-speed pneumatic motor and a grinding wheel automatic reciprocating motion mechanism. The utility model not only can be used for grinding a hard alloy material, but also can be used for grinding a horn hole with a circle arc-shaped longitudinal section.

Description

Pneumatic high speed grinding machine of universal

The utility model relates to the Machining Technology field, relates to a kind of Metal Cutting Machine Tool, and particularly a kind of grinding machine is suitable for the inside and outside circle and the end face of workpiece are carried out grinding.

Existing grinding machine of universal mainly is made up of lathe bed, the headstock, tailstock, grinding carriage, interior round grinding tool, workbench, saddle and transverse feed mechanism, because its grinding carriage can only be adjusted the angle position under off working state, can't the grinding vertical section be the bellmouth orifice of arc therefore; In addition, grinding carriage motor and interior round grinding tool motor all adopt common power frequency motor, so grinding wheel speed low (the internal grinder grinding wheel speed also has only 1～20,000 commentaries on classics), not only efficient is low, the treatment of surfaces of components fineness is not high, and can not process the higher alloy material of some hardness.Existing employing intermediate frequency or high-frequency electric machines internal grinder, although grinding wheel speed can reach more than 100,000 commentaries on classics, its grinding carriage can not be adjusted the angle position down in working order, can't the grinding vertical section be the bellmouth orifice of circular arc also; In addition, motor not only will be equipped with the frequency conversion unit, and will dispel the heat with cooling water.

In view of there is above-mentioned deficiency in prior art, but the purpose of this utility model provides the pneumatic high speed grinding machine of universal that a kind of grinding vertical section is the circular arc bellmouth orifice.

The utility model realizes that the technical solution of above-mentioned purpose is as described below:

A kind of pneumatic high speed grinding machine of universal is characterized in that the side of cross slide is hinged with the revolving wheel frame, and this revolving wheel frame is connected and composed from bottom to top successively by rotating mechanism, manual radius governor motion, high-speed pneumatic motor and the husky mechanism that automatically moves back and forth of taking turns.

The utility model has following outstanding advantage and effect than prior art:

1. because the pivot of rotating mechanism is the formation vertical section to the horizontal range of wheel face is the circular arc bus radius of the bellmouth orifice of circular arc, therefore handle manual radius governor motion, can determine the operating position of emery wheel easily, drive whole revolving wheel frame and rotate around the pivot of rotating mechanism, accurately the grinding vertical section is the bellmouth orifice of circular arc;

2. use high-speed pneumatic motor to drive emery wheel, the speed height, device is simple, and volume is little, and cost is low;

3. the function multipurpose is wide, not only can grinding cylinder shape or the cylindrical and the endoporus of taper, and change emery wheel also can the grinding plane.

Below in conjunction with drawings and Examples the utility model is carried out further detailed description,, grasp better and implement technological means of the present utility model so that the public fully understands technical solution of the present utility model.

Fig. 1 Fig. 2 and Fig. 3 are the structural representation of a specific embodiment of the present utility model, and wherein Fig. 1 is a front view, and Fig. 2 is a left view, and Fig. 3 is vertical view (sheds the mechanism that automatically moves back and forth, and make whole revolving wheel frame be in the operating position);

Fig. 4 is the structural representation of air motor;

Fig. 5 Fig. 6 and Fig. 7 are the structural representation of impeller 14 among Fig. 4, and wherein Fig. 5 is a front view, and Fig. 6 is a vertical view, and Fig. 7 is an A-A cutaway view among Fig. 5;

Fig. 8 and Fig. 9 are the structural representation of driving chip 15 among Fig. 4, and wherein Fig. 8 is a front view, and Fig. 9 is a vertical view.

Referring to Fig. 1 and Fig. 3, in order to improve the stability of described revolving wheel frame, an important additional technical feature of the present utility model is to be provided with arc-shaped guide rail 9 between the dovetail guide 4 in cross slide 1 and the manual radius governor motion.The arc guide barrel of dovetail guide 4 bottoms contacts with the good of arc-shaped guide rail 9, and the cutting force of emery wheel 10 is reached lathe bed 11, and revolving wheel frame instability influences machining accuracy when avoiding emery wheel 10 work.

Referring to Fig. 1 Fig. 2 and Fig. 3, the described pneumatic high speed grinding machine of universal of present embodiment is to form at the hinged revolving wheel frame 2 of cross slide 1 left surface of existing desk-top internal grinder.Described revolving wheel frame 2 is connected and composed from bottom to top successively by rotating mechanism, manual radius governor motion, high-speed pneumatic motor and the husky mechanism that automatically moves back and forth of taking turns.Wherein, rotating mechanism is hinged on the centre bearing piece 3 by being fixed on the centre bearing piece 3 and the end of cross slide 1 in the side, the pivoted arm 17 that the other end is fixed on dovetail guide 4 left surfaces that are positioned at cross slide 1 top is formed, the operator pulls handle 12 with hand, and whole revolving wheel frame can prop up piece 3 around the center and rotate; The structure of manual radius governor motion is identical with the transverse feed mechanism on the common metal stock-removing machine, mainly is made up of dovetail guide 4, the slide plate 5 on dovetail guide 4, feed screw and the nut (not showing among the figure) that is located between dovetail guide 4 and the slide plate 5; Described slide plate 5 takes the shape of the letter U, and high-speed pneumatic motor 6 is established within it, is suspended on the longitudinal slide 7; The husky wheel mechanism that automatically moves back and forth props up and is on the two side of U-shaped slide plate 5, mainly is made up of the longitudinal slide 7 that can slide on U-shaped slide plate 5 and driving longitudinal slide 7 reciprocating slider-crank mechanisms (not showing among the figure) and buncher 8.

Referring to Fig. 4 and in conjunction with Fig. 5～Fig. 9, air motor 6 described in the utility model is established with reference to the external pneumatic grinding tool of import high speed and is formed, and the right-hand member of main shaft 13 is fixed with impeller 14, and the right side of impeller 14 is provided with driving chip 15 and supplying air disc 16 successively; The shape of supplying air disc 16 is especially as a general bearing (ball) cover, the edge annular is distributed with fresh air inlet, the edge symmetry tangential distribution of driving chip 15 has three waist shape taper holes, the edge of impeller 14 is densely covered with tangential folding hole corresponding to the exit annular of waist shape taper hole on the driving chip 15, compressed air from the supplying air disc 16 fresh air inlet and driving chip 15 on waist shape taper hole enter tangential folding hole on the impeller 14, produce powerful moment of torsion, drive shaft is rotated at a high speed, more than speed is changeed up to 100,000.Compressed air is not only power source, and both grease can be taken in the bearing, the frictional heat that bearing produces can be taken out of again.

Implementation method beyond the utility model is above-mentioned can be utilized prior art and implement to get final product with reference to accompanying drawing.
