The course of work and the principle of calibration location are: when the cylinder body (8) of calibration positional cylinder unclamps chamber feeding pressure oil; Piston (9) moves to left pushing drawing rod (12), mandrel (4), last fluted disc (2) (lifting) together with dividing head (1) integral body, and last fluted disc (2) breaks away from (unclamping) with lower tooth disk (3); At this moment, as long as roller shaft (15) rotation just can be passed through its gear (17) and gear (5) drive mandrel (4), gone up fluted disc (3), dividing head (1) revolution, carry out calibration.
After indexing position arrives; As long as the clamping chamber at cylinder body (8) feeds pressure oil; Piston (9) will promote mandrel (4) through locking nut (6), go up fluted disc (2) together with dividing head integral body such as (1) move to right (falling); Last fluted disc (2) and lower tooth disk (3) engagement (clamping) are accurately located.
Adjustment adjusting nut (13) can change the distance of lifting that goes up fluted disc (2).
The rotating course of work of calibration and principle are: when last fluted disc (2) when unclamping; Turning rolls (18) can convert the motion of conjugate cam (24) into gyration with the roller disk that ball (19) is combined into; And, driven gear (5), mandrel (4), go up fluted disc (2), dividing head (1) rotation through roller shaft (15) and the gear (17) that is attached thereto.
First rear bearing (16) in the movement conversion mechanism, fore bearing (21) have guaranteed the rotation of roller shaft (15); First adjusting pad (14) and the 4th adjusting pad (22) are used for adjusting the axial location of movement conversion mechanism; Bearing block (23), locking nut (20) are used for fixing roller shaft (15), turning rolls (18).
Second rear bearing (28) of cam drive mechanism, fore bearing (32) have guaranteed the rotation of camshaft (26); Second adjusting pad (27) and the 3rd adjusting pad (29), spacer (31) are used for adjusting the axial location of conjugate cam (24); Bearing block (33), locking nut (30) are used for fixing camshaft (26), conjugate cam (24); The axle head hollow belt keyway of camshaft (26) is used to connect the output shaft of reduction box (34).
Extremely shown in Figure 5 like Fig. 4: roller disk divides two-layer up and down, ball dislocation layout, and total ball number equates with the number of divisions.The levels ball of roller disk can alternately mesh with conjugate cam (24), smooth transition; Conjugate cam (24) rotates a week, and roller disk will turn over a minute of angle.Such structure can guarantee when conjugate cam is constant, only needs to change the radius and the ball quantity of roller disk, just can change minute of angle; And can dwindle the volume of mechanism.The structure of ball is identical with needle bearing, also can directly use needle bearing to replace.
Fig. 6 is to shown in Figure 7: conjugate cam (24) has two cams up and down, 45 ° of symmetric arrangement of two cams, and its rotating motion process is identical.When conjugate cam (24) rotated, cam will be alternately and the levels engagement of roller disk up and down, steadily acceleration and deceleration and transition.
Fig. 8 is to shown in Figure 13: assumed position 1 is the original position of conjugate cam (24), and when cam was turned back to position 2 clockwise, overhead cam began and the ball engagement, can drive roller disk and steadily quicken and be rotated counterclockwise position 3; In 3 zones, position, the radius of following cam is constant, do not play driving action in position 1.When conjugate cam (24) in-position 3, following cam begins and the ball engagement, continues to drive roller disk and is rotated counterclockwise position 4; The radius of this zone overhead cam is constant, do not play driving action.When conjugate cam (24) in-position 4, overhead cam meshes with ball once more, continues to drive roller disk and is rotated counterclockwise position 5; Under this zone the radius of cam constant, do not play driving action.From the position 5 to the position 2 whole zone, the radius of cam is all constant up and down, as long as drive unit can stop in this zone, just dividing head can accurately navigate on the indexing position.
Above cam locus makes the continuous motion district of roller disk nearly double than Geneva mechanism, and can guarantee steady acceleration and deceleration, and its motion has not had tangible gap.
Principle of the present invention is: as long as can guarantee that through above-mentioned cam mechanism drive unit can stop, and just can accurately locate near indexing position; And when turning round continuously; Cam locus can be realized steady acceleration and deceleration again and near continuous motion, and it has solved the continuous division problem, counter-rotating retaining mechanism of the motion shock problem of Geneva mechanism, common hydraulic pressure circular dividing table can only unidirectional revolution and the problem of location " anti-leaning on ".The minute of angle of circular dividing table changes and can realize simply through the conversion roller disk, need not to change conjugate cam and miscellaneous part, and its versatility is good, flexibility strong, adjustment is easy, be convenient to the scale volume production.Even if circular dividing table adopts common electric machine, the revolution of hydraulic gyration hydraulic oil cylinder driving also can guarantee not have the continuous division of impact, its reliable in action, calibration are quick.
All parts processing of technique scheme all circular dividing table process equipment of available routine are accomplished simply; The processing and manufacturing cost of circular dividing table is low, installs, adjusts and keep in repair to be very easy to.
