Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Figure 1 shows that an embodiment of raceway groove clamp for grinding in the utility model clutch can, this processing unit (plant) is on common M2120 grinding machine, is connected by base 7 by the magnetic suction disc of grinding machine with M2120 guideway of grinding machine.Base 7 is equipped with two angular contact ball bearings 6, stop bit pin 4 and bearing block 8, and fixture casing 9 is connected with bearing block 8 by bolt 5.At the axis place of fixture casing 9, a main shaft 12 is housed, this main shaft 12 is multidiameter, in the short end of main shaft 12, angular contact ball bearing 13 is housed.In the long end of main shaft 12, worm gear 11 is housed, split bush 15 and fixture cover 3.Worm gear 11 is connected with main shaft 12 with flat key 17 respectively by flat key 14 with fixture cover 3, at the large end of fixture cover 3, angular contact ball bearing 1 is housed.During assembling, in bearing, add moderate lubrication fat, by angular contact ball bearing adjustment assembly gap.Processed clutch can is threaded connection mode and is clamped in the endoporus of main shaft 12 long end, and is fixed further by bolt 2 at the large end of fixture cover 3.Below worm gear 11, with main shaft 12 vertical direction, worm screw 10 is housed.As shown in Figure 2, deep groove ball bearing 18,19 is equipped with at worm screw 10 two ends, is connected with fixture casing 9.As shown in Figure 3, with main shaft 12 vertical direction, with the two ends, cover wall opening downward place of split bush 15, first push rod 20, second push rod 21, second push rod 21 is housed and is fixed on fixture casing 9 by nut 22, the first push rod 20 is by the rotation that is threaded.Worm screw 10 often rotates 60 °, drives main shaft 12 calibration 60 °, rotates the first push rod 20 split bush 15, locking main shaft 12.
At assembling process with ensureing: 1. main-shaft axis and parallelism error≤0.015, base baseplane; 2. stop bit pin and base baseplane intersect vertically error≤0.025.
