Abstract

The utility model relates to a numerical-control middle-high device, belonging to the numerical-control middle-high device in the machine-tool middle-high grinding or machining. The numerical-control middle-high device comprises a retarder, a lever, a ball screw mandrel, a worm wheel as well as a worm, and a motor, wherein, the ball screw mandrel (14) is vertically arranged in a reduction box (1); the worm wheel (23) which is meshed with the worm (21) and a T-shaped nut (24) are arranged on the ball screw mandrel; the worm is arranged on a reduction box body through a blind flange (22) and a flange sleeve (20); the worm is connected with a motor (18) through a shaft coupling (19); the left end of the lever (4) is supported on a bearing surface of the T-shaped nut through a shaft (25) and a fork groove of a bearing (26); the right end of the lever is supported in a guide way on a pedestal (15) through a rotating shaft (16) and the bearing (17); a piston post rod (11) in the middle of the lever props an idler wheel (5) arranged on a shell body (6). The numerical-control middle-high device simplifies the structure, eliminates the bad influences to the grinding or machining precision caused by the transmission clearance, simplifies the mechanical transmission, and lowers the processing cost, thereby increasing the grinding precision of the machine tool. Therefore, the numerical-control middle-high device is applied to the middle-high grinding of a roll grinder, a plain grinder and other machine tools.

Description

High device in the numerical control

Technical field: the utility model relates to numerical control device, high device in particularly a kind of numerical control that is used for roll grinder, cylindrical grinder and high grinding of other lathe or processing.

Background technology: in the prior art high grinding be by high change gear in the planker gear driven, in high cam, in high leverage, the mill frame is kowtowed realizes.This device transmission chain length, drive gap are big, control is complicated, it is loaded down with trivial details to process and assemble, cost is high, low, the control poor sensitivity of high accuracy in the grinding.

Summary of the invention: the purpose of this utility model is to provide high device in a kind of numerical control, drives worm gear, worm screw, ball screw rotation by servomotor, reduces driving-chain, reduces drive gap significantly, realizes numerical control.Thereby make lever swing realize that the mill frame kowtows, high numerical control grinding in the realization reaches the purpose of high grinding accuracy in the raising.

Formation of the present utility model: by decelerator, loam cake, bearing block, stand, lever, worm gear, worm screw, piston, blind flange, rotating shaft, bearing, ball screw, adjusting pad, axle, motor and shaft coupling are formed, ball screw 14 is vertically mounted in the reduction box 1, be fixed on the loam cake 3 by blind flange 2 above, be installed in below on the bearing block 13, there is adjusting pad 12 bottom, worm gear 23 with worm screw 21 engagements is installed on ball screw 14, worm screw 21 is installed on the deceleration box by blind flange 22 and flange cover 20, worm screw 21 is connected with motor 18 by shaft coupling 19, T type nut 24 is installed on ball screw, the left end of lever 4 is supported on the bearing-surface of T type nut by the fork groove of axle 25 and bearing 26, the right-hand member of lever is supported on rotating shaft 16 and bearing 17 in the gathering sill on the stand 15 of tape guide groove, and the piston mandril 11 at lever middle part withstands the roller 5 that is installed on the upper shell 6.

Compared with the prior art, the utility model changes high grinding in the original complicated mechanical transmission in the numerical control high grinding; Simplify the structure, eliminated the adverse effect of drive gap, simplified machine driving, cut down finished cost and shorten installation period, thereby improve the grinding accuracy of lathe grinding or machining accuracy.

Description of drawings: Fig. 1 is the utility model structural representation, and Fig. 2 is the A-A cutaway view of Fig. 1, and Fig. 3 is the B-B cutaway view of Fig. 1, and Fig. 4 is the C-C cutaway view of Fig. 1.

1. reduction boxes among the figure, 2. blind flange, 3. loam cake, 4. lever, 5. roller, 6. upper shell, 7. emery wheel, 8.O point, 9. lower house, 10.01 points, 11. push rod, 12. adjusting pads, 13. bearing blocks, 14. ball screws, 15. stand, 16. rotating shafts, 17. bearings, 18. motors, 19. shaft coupling, 20. flange covers, 21. worm screws, 22. blind flanges, 23. worm gear, 24.T type nut, 25., 26. bearings.

The specific embodiment: as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, ball screw 14 is vertically mounted in the reduction box 1, be fixed on the loam cake 3 by blind flange 2 above, be installed in below on the bearing block 13, there is adjusting pad 12 bottom, worm gear 23 with worm screw 21 engagements is installed on ball screw 14, worm screw 21 is installed on the deceleration box by blind flange 22 and flange cover 20, worm screw 21 is connected with motor 18 by shaft coupling 19, T type nut 24 is installed on ball screw, the left end of lever 4 is supported on the bearing-surface of T type nut by the fork groove of axle 25 and bearing 26, the right-hand member of lever is supported on rotating shaft 16 and bearing 17 in the gathering sill on the stand 15 of tape guide groove, and the piston mandril 11 at lever middle part withstands the roller 5 that is installed on the upper shell 6.

Operation principle: AC servo motor 18 drives 23 rotations of worm screw 21 worm gears through shaft coupling 19, drive ball screw 14 revolutions, because the restriction of the left end fork pockets of lever 4, T type nut 24 moves up and down along ball screw 14 spirals, thereby activation lever 4 is around 01: 10 swing, the push rod 11 promotion mill frame upper shells 6 at lever middle part are swung around mill frame lower house 9 anterior rotation pole O points 8, thereby made emery wheel cut or withdraw from, high curve during the surface of the work grinding forms to the workpiece trace.

The mill frame is moving back and forth simultaneously with saddle, and planker pulse signal transmitter sends instruction, and middle servomotor is by the instruction rotation, thereby driving emery wheel cuts or withdraws from, realize camber grinding, i.e. saddle numerical control axle with in high grinding numerical control axle interlock, high grinding in the realization.
