Sealing pair eccentric grinder and method thereof
Technical field
The present invention relates to and belongs to grinding machinery field, and what be specifically related to is a kind of sealing pair eccentric grinder and method thereof.
Background technology
Grinder is the special mechanical equipment that carries out polishing grinding technics, is indispensable in mechanical processing process.Existing grinder adopts the mode of semi-automatic direct grinding conventionally, replaced part hand labor, but its machining accuracy is low, efficiency is low, can only grind simple workpiece, not be suitable for the attrition process that high accuracy complex part is for example had to the sealing pair of strict seal request.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of sealing pair eccentric grinder and method thereof are provided.
Sealing pair eccentric grinder comprises motor, control panel, column, workbench, platform lifting device, automatic clamping device, lower grinding head, upper eccentric grinding head, main shaft, cantilever handle, grinds pawl, lubricated flexible pipe, cantilever, bearing holder (housing, cover), speed changer, motor output shaft is connected by shaft coupling with transmission input shaft, transmission output shaft is connected by shaft coupling with main shaft, grinding pawl is installed on main shaft end and clamps upper eccentric grinding head, between upper eccentric grinding head and lower grinding head, be connected, speed changer is bolted on cantilever, control panel, cantilever handle, lubricated flexible pipe, bearing holder (housing, cover) is all fixed on cantilever, workbench, platform lifting device, the equal encapsulation of cantilever is on column, platform lifting device drives workbench lifting by hydraulic jack, two automatic clamping devices are installed on workbench (4), by hydraulic jack, directly drive and realize, automatic clamping device move radially employing lever principle, make radially synchronizing moving of two pawls.
Described sealing pair eccentric grinder, the speed of mainshaft, by speed changer direct-drive, has function of stepless speed regulation.
The eccentric Ginding process of sealing pair comprises the following steps:
1) choose eccentric grinding head and lower grinding head correct installation;
2) workpiece to be processed be positioned on workbench and clamp;
3) adjust the height of workbench and the angle of cantilever and make lower grinding head and sealing pair to be processed laminating;
4) slightly determine operating position and start shooting to try out and carry out further fine position;
5) according to the material of workpiece to be processed and processing request, input program start to grind in control panel;
6) upper eccentric grinding head revolves round the sun under the drive of grinding pawl, and lower grinding head is under the drive of upper eccentric grinding head, because the impact of eccentric force is rotated voluntarily;
7) according to material category and requirement on machining accuracy replacing sand paper, carry out fine grinding or fine grinding.
Using beneficial effect of the present invention to embody is: compared with prior art, the present invention adopts centering type bistrique to grind, and makes bistrique produce rotation in revolution, utilizes double weft to turn to and net formula flour milling principle, significantly improve grinding effect, improve grinding precision.Meanwhile, the present invention has adopted advanced structural design, and the assembly method of Split assembled makes quick for installation, simply, and the present invention is lightweight, volume is little, so applicable to the field operation under various environment.

In figure, motor 1, control panel 2, column 3, workbench 4, platform lifting device 5, automatic clamping device 6, lower grinding head 7, upper eccentric grinding head 8, main shaft 9, cantilever handle 10, grinding pawl 11, lubricated flexible pipe 12, cantilever 13, bearing holder (housing, cover) 14, speed changer 15.
The specific embodiment
As shown in Figure 1, 2, sealing pair eccentric grinder comprises motor 1, control panel 2, column 3, workbench 4, platform lifting device 5, automatic clamping device 6, lower grinding head 7, upper eccentric grinding head 8, main shaft 9, cantilever handle 10, grinds pawl 11, lubricated flexible pipe 12, cantilever 13, bearing holder (housing, cover) 14, speed changer 15, motor 1 output shaft is connected by shaft coupling with speed changer 15 power shafts, speed changer 15 output shafts are connected by shaft coupling with main shaft 9, grinding pawl 11 is installed on main shaft 9 ends and clamps upper eccentric grinding head 8, upper eccentric grinding head 8 and 7 of lower grinding heads are connected, speed changer 15 is bolted on cantilever 13, control panel 2, cantilever handle 10, lubricated flexible pipe 12, bearing holder (housing, cover) 14 is all fixed on cantilever 13, workbench 4, platform lifting device 5, the equal encapsulation of cantilever 9 is on column 3, platform lifting device 5 drives workbench 4 liftings by hydraulic jack, two automatic clamping devices 6 are installed on workbench 4, by hydraulic jack, directly drive and realize, automatic clamping device 6 move radially employing lever principle, make radially synchronizing moving of two pawls.
Main shaft 9 rotating speeds, by speed changer 15 direct-drives, have function of stepless speed regulation.
The eccentric Ginding process of sealing pair comprises the following steps:
1) choose eccentric grinding head 8 and lower grinding head 7 correct installation;
2) workpiece to be processed be positioned on workbench 4 and clamp;
3) adjust the height of workbench 4 and the angle of cantilever 5 and make lower grinding head 7 and sealing pair laminating to be processed;
4) slightly determine operating position and start shooting to try out and carry out further fine position;
5) according to the material of workpiece to be processed and processing request, input program start to grind in control panel 2;
6) upper eccentric grinding head 8 revolves round the sun under the drive of grinding pawl 11, and lower grinding head 7 is under the drive of upper eccentric grinding head 8, because the impact of eccentric force is rotated voluntarily;
7) according to material category and requirement on machining accuracy replacing sand paper, carry out fine grinding or fine grinding.
