Description
Technical field
The utility model relates to a kind of grinding tool, relates in particular to a kind of crankshaft grinding processing emery wheel group.
Background technology
At present, domestic conventional automobile engine crankshaft grinding, generally adopt monolithic emery wheel repeatedly to process, inefficiency, machining accuracy are poor like this, how the emery wheel of monolithic can be combined and to use together, crankshaft grinding adds one-shot forming in man-hour, becomes the art staff and is badly in need of the major issue solving.
Utility model content
The purpose of this utility model adopts monolithic emery wheel while being to solve the grinding of prior art automobile engine crankshaft, inefficiency, the poor defect of machining accuracy provide the crankshaft grinding processing that a kind of operating efficiency is high, machining accuracy is high emery wheel group.
The technical solution adopted in the utility model is:
It is a kind of crankshaft grinding processing emery wheel group, it is characterized in that comprising main shaft, chuck, locating ring and emery wheel, described emery wheel is 2-7 sheet, be sleeved on main shaft, the both sides of every emery wheel are all provided with the chuck being fixed on main shaft and are clamped, between adjacent two emery wheels, be provided with locating ring, locating ring is between two adjacent chucks, described every emery wheel is by the clamping part of inner side and the grinding part in outside composition, described milled portion is three layers, the two-layer rose grain layer in left and right, intermediate layer is white fused alumina abrasive material, on white fused alumina abrasive material, be distributed with multiple micro-pores and be provided with chip removal groove on two-layer rose grain layer outer face, chip removal groove radially distributes, angle of inclination is 10 °-25 °.
The aperture size of micro-pore described in the utility model is at 0.4-0.6mm.
Between adjacent two emery wheels, be provided with 1 locating ring, size, the thickness of each locating ring are all identical.
Clamping part of the present utility model belongs to inoperative position, does not play ablation, is mainly gain in strength and reduce costs.
The thickness of rose grain layer is 5mm, and toughness is better, is used for two R angles of grinding main bearing journal and crank root, is conducive to keep preferably the shape at R angle, improves grinding accuracy.
White fused alumina abrasive material and trunnion contact-making surface are larger, and cutting power is more intense, and with micro-pore (adding pore former), can improve grinding efficiency, reduce finishing number of times, prevent from being ground position and occur burn.
The effect of chip removal groove is chip removal, dispels the heat, prevents to burn.
The utlity model has advantage rational in infrastructure, that cost is low, easy to use, ground effect good, precision is high.Use the utility model can realize synchronous finishing, synchro-feed, synchronous grinding, synchronism is good.

As shown in Figure 3: the clamping part 4-3 that comprises inner side of every emery wheel 4 and the grinding part in outside, grinding part comprises the rose grain layer 4-2 of the left and right sides and middle white fused alumina abrasive material 4-1, is distributed with multiple micro-pores on white fused alumina abrasive material 4-1.
As shown in Figure 2: the rose grain layer 4-2 outer face of every emery wheel 4 is provided with and radially distributes, angle of inclination is the chip removal groove 5 of 10 °-25 °.
When the utility model is made, use the full machining tool of numerical control with diamond segment, on same grinding machine, emery wheel 4 planes, aperture and external diameter are processed, can guarantee the perpendicularity of emery wheel 4 apertures and plane.
The utility model design accuracy is high, the poor 1mm that is not more than of outside dimension, and be not more than ± 0.08mm of gauge deviation, end face run-out is not more than 0.07mm, and static balance grams is not more than 50% of GB setting, and Wheel hardness, even tissue are consistent.Can realize synchronous finishing, synchro-feed, synchronous grinding.Good by mill crankshaft journal shape retention, dimensional accuracy is high, and result of use is good.
The utility model is not limited to above embodiment, and according to the bent axle type of processing, emery wheel can also be selected 2,5,6.
