Description
Technical field
The utility model relates to machine tool field, specifically a kind of bearing shell grinder.
Background technology
As everyone knows, the plain external grinding machine grinding carriage generally needs eight bearing shells that the grinding carriage main shaft is supported, and contacts for sphere between bearing shell and the strong point; For guaranteeing machine mass; Bearing shell and strong point sphere need grind, and it generally is to adopt artificial manual operations that traditional bearing shell contact sphere grinds, and once can only grind a bearing shell; Efficient is lower, has influenced the assembling speed of lathe.
Summary of the invention
In order to overcome the deficiency of lathe prior art, the utility model provides a kind of bearing shell grinder, has greatly improved the grinding rate of bearing shell, has improved the Grinding Quality of bearing shell sphere, and easy to use, simple in structure, safe and reliable.
The utility model solves the technical scheme that its technical problem adopted: a kind of bearing shell grinder, be provided with variable-frequency motor, and it is characterized in that; Be fixed with sun gear in the variable-frequency motor rotating shaft, two planetary gears and sun gear engagement, two planetary gears are installed in the internal gear; The planetary gear terminal pad is fixed on the planetary planet pin, and the planetary gear terminal pad is fixed on the eccentric shaft upper end, and the eccentric shaft bottom is installed on the base; Eccentric shaft is installed in the connecting cylinder; Connecting cylinder links to each other with the joint terminal pad through key, and the active joint terminal pad is hinged with joint, and the active joint lower end is fixed with the bearing shell supporting screw.
The beneficial effect of the utility model is, greatly improved the grinding rate of bearing shell, improved the Grinding Quality of bearing shell sphere, and easy to use, simple in structure, safe and reliable.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
Among the figure: 1. sun gear, 2. planet pin, 3. planetary gear, 4. planetary gear terminal pad, 5. internal gear, 6. eccentric shaft, 7. connecting cylinder, 8. joint terminal pad, 9. active joint, 10. bearing shell supporting screw, 11. bearing shells, 12. bases.
The specific embodiment
The utility model is provided with variable-frequency motor in Fig. 1, is fixed with 1, two planetary gear of sun gear 3 and sun gear 1 engagement in the variable-frequency motor rotating shaft; Two planetary gears 3 are installed in the internal gear 5; Planetary gear terminal pad 4 is fixed on the planet pin 2 of planetary gear 3, and planetary gear terminal pad 4 is fixed on eccentric shaft 6 ends, and eccentric shaft 6 bottoms are installed on the base 12; Eccentric shaft 6 is installed in the connecting cylinder 7; Connecting cylinder 7 links to each other with joint terminal pad 8 through key, and joint terminal pad 8 is hinged with active joint 9, and active joint 9 lower ends are fixed with bearing shell supporting screw 10.
Earlier bearing shell 11 is installed on the base 12 when the utility model uses and fixes, need to grind sphere and be coated with abrasive sand, active joint 9 and bearing shell supporting screw 10 are installed.Press start button (forward or reverse), variable-frequency motor drives sun gear 1 and rotates, and sun gear 1 drives 2 planetary gears 3 and in internal gear 5, moves in a circle.Planetary gear 3 drives planetary gear terminal pad 4 through planet pin 2 and rotates, and planetary gear terminal pad 4 drives eccentric shaft 6 and in connecting cylinder 7, rotates, and connecting cylinder 7 drives joint terminal pad 8 through the key connection and does centrifugal motion.The drive active joint 9 and the bearing shell supporting screw 10 of joint tie-plate 8 done on bearing shell 11 and ground motion.
