Description
Technical field
The present invention relates to a kind of grinder, particularly relate to a kind of sphere grinding machine.
Background technology
In machinery industry, there is a large amount of mating parts, the quality of fit of some of them part requires higher, needs to carry out attrition process.
Attrition process coordinates brushing abrasive pastes on contact surface at two, then makes it issue raw relative motion at certain adhesive force, and then utilize abrasive pastes to carry out the processing mode of micro cutting to mating surface.
The equipment realizing attrition process mode is referred to as grinder, generally can process various metal and nonmetallic materials, and the surface configuration of processing has plane, the inside and outside face of cylinder, taper seat, convex, concave spherical surface, flank, the flank of tooth and other profiles.Machining accuracy can reach IT5 ~ 01, and surface roughness can reach Ra0.63 ~ 0.01 micron.
Common grinder can be divided into five kinds substantially according to operation principle: drum grinder, oscillating mill, centrifugal grinder, erratic current grinding mill and mixer grinder.
Common Ginding process generally can be divided into and wet to grind, dryly to grind and half-dried Kenzo class:
1. wet and grind: also known as stuccoing grinding, liquid grinding agent is annotated continuously or is coated in lapped face, abrasive material constantly slides and rolls between workpiece and lap tool, formation cutting movement.Wet grinding is generally used for rough lapping, and micron power granularity used is coarser than W7.
2. dryly to grind: grind also known as embedding sand, abrasive material is evenly embedded in lap tool superficial layer in pressure, during grinding, the auxiliary material such as a small amount of stearic acid mixing fat need only be coated with on lap tool surface.Dry grinding is usually used in smooth grinding, and micron power granularity used is narrower than W7.
3. half-driedly to grind: similarly wetly to grind, grinding agent used is pasty state abrasive pastes.Grinding both with manual operations, also can be carried out on grinder.Workpiece first must obtain higher preprocessing precision by other processing methods before the milling, and grind of staying is generally 5 ~ 30 microns.
The output of China's plunger type hydraulic pump/motor was every year on average probably at about 160,000 in recent years, every platform plunger type hydraulic pump/motor at least needs a set of movement part, cylinder body 1 in most movement part and the cooperation between valve plate 2 are mating spherical surfaces 3 (as shown in Figure 1), and quality of fit is higher, these coordinate sphere all to need to carry out attrition process, and also there is no at present a kind of grinder of the special sphere attrition process design for the cylinder body of plunger type hydraulic pump/motor and the part of this kind of mating spherical surfaces of valve plate, the cylinder body of usual plunger type hydraulic pump/motor and the sphere of valve plate are all carry out underhand polish before assembly, waste time and energy, production efficiency is low.
