Description
Technical field
The utility model relates to a kind of aid of grinding machine, relates in particular to a kind of extension bar that is used for the universal cutter grinder emery wheel.
Background technology
Universal cutter grinder can grind slotting cutter and end mill(ing) cutter usually, can also grind such as special-shaped milling cutters such as cotter mill cutters, and machine tools such as screw tap and drill bit, can also ground flat and the cylindrical of small-diameter sized.Some special-shaped cutter is often needed to grind endoporus, because universal cutter grinder emery wheel shank is shorter, grinding for endoporus truly has certain difficulty, and the minimum-value aperture that can carry out attrition process usually is 150mm, almost can not carry out attrition process for the endoporus of small-bore again.
The utility model content
At above-mentioned prior art, the utility model provides a kind of universal cutter grinder emery wheel extension bar, the endoporus that utilizes the utility model not only can make universal cutter grinder carry out the small-bore workpiece grinds, if cooperate suitable emery wheel again, can also carry out attrition process to some special-shaped cutters.Simultaneously, this emery wheel extension bar also can use and grind on the hole type parts.
In order to solve the problems of the technologies described above, the utility model is used for the technical scheme that the emery wheel extension bar of universal cutter grinder is achieved: comprise the body of rod, one end of the described body of rod is provided with shoulder hole, described shoulder hole is made of first taper hole of outer end and the cylindrical hole of inner end, be provided with a lock-screw in the described shoulder hole, described lock-screw is provided with radial direction through hole, and the hole wall of described cylindrical hole is provided with the radial hole of perforation, has a spacer pin to cooperate with described radial direction through hole and radial hole; The described body of rod other end is provided with second taper hole, and the spindle nose of this end is provided with nut, is provided with sleeve in described second taper hole, and described sleeve is an elastic component, the collar and the draw-in groove of fit in the collar extension place of described nut and described sleeve is provided with.
The utility model is used for the emery wheel extension bar of universal cutter grinder, wherein, the cone match of described first taper hole and grinding machine spindle, described lock-screw cooperates with the internal thread hole of grinding machine spindle; The internal diameter of described sleeve is slightly larger than the external diameter of emery wheel handle.The outer surface of the described body of rod is provided with the annular knurl structure.The outer surface of the described body of rod is provided with and mills flat structure.
Compared with prior art, the beneficial effects of the utility model are: because the two ends of the utility model emery wheel extension bar are respectively equipped with taper hole and the locking mechanism that connects grinding machine spindle and emery wheel handle, one end of emery wheel extension bar is by locating with the conical surface of 11.5 ° of main shafts of grinding machine, and utilize built-in lock-screw of emery wheel extension bar and spacer pin, therefore, can be implemented on the general universal cutter grinder axis hole workpiece of aperture between 70-80mm carried out attrition process, in addition, if cooperate corresponding end face again is the band handle emery wheel of cambered surface, can grind the inner arc surface of special-shaped cutter, thereby expand the range of work of universal cutter grinder.
Description of drawings
Accompanying drawing 1 is structure and the scheme of installation that the utility model is used for the emery wheel extension bar of universal cutter grinder.
Among the figure: 1. grinding machine spindle, 2. lock-screw, 3. spacer pin, the 4. body of rod, 5. nut, 6. sleeve, 7. emery wheel handle, 8. mill flat, 9. annular knurl, 10. motor.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done to describe in further detail.
Shown in the figure accompanying drawing, the utility model is used for the emery wheel extension bar of universal cutter grinder, comprise the body of rod 4, one end of the described body of rod 4 is provided with shoulder hole, described shoulder hole is made of first taper hole of outer end and the cylindrical hole of inner end, wherein, the cone match of described first taper hole and grinding machine spindle 1, the location that is used for the emery wheel extension bar, be provided with a lock-screw 2 in the described shoulder hole, described lock-screw 2 cooperates with the internal thread hole of grinding machine spindle 1, described lock-screw 2 is provided with a radial direction through hole, be provided with a radial hole that connects at the length range that is positioned at cylindrical hole on the described body of rod 4, have a spacer pin 3 to pass described radial direction through hole and radial hole, thus the location of realizing emery wheel extension bar and grinding machine spindle 1 be connected; The other end of the described body of rod 4 is provided with second taper hole, the spindle nose of this end is provided with nut 5, be provided with sleeve 6 in described second taper hole, described sleeve 6 is an elastic component, the collar and the draw-in groove of fit in the collar extension place of described nut 5 and described sleeve 6 is provided with rely on the elasticity of sleeve 6 that this sleeve 6 is clamped in the nut 5, because the internal diameter of described sleeve 6 is slightly larger than the external diameter of emery wheel handle 7, therefore, can the emery wheel spindle clamp is tight by screwing of nut 5.
For the ease of the emery wheel extension bar is installed, on the outer surface of the described body of rod 4, be provided with the annular knurl structure.Be provided with on the outer surface of the described body of rod 4 for the ease of tool using and mill flat structure.
