Abstract
The utility model discloses a feeding and compensating mechanism for an inner circle grinding machine, which comprises a machine base, an oil cylinder arranged in the machine base, a lever connected with the oil cylinder, a ball screw arranged above the lever, a nut arranged on the ball screw, a sliding plate arranged at the left side of the ball screw, a spline sleeve sleeved at the right side of the ball screw, and a coupler connected with the spline sleeve, wherein a spring connected with the machine base is arranged on the sliding plate, the lever is further provided with a reset spring and a reset screw which are connected with the machine base, and a servomotor is arranged on the coupler; the compensating mechanism adopts the servomotor and the ball screw to replace the three-roller-wheel type friction clutch in the prior art, so that the original structure is utilized sufficiently, in addition, the feeding and compensating accuracy, efficiency and reliability of the equipment are simultaneously improved.
Description
Technical field
The utility model relates to a kind of compensation mechanism, particularly a kind of bearing internal grinder feed compensation mechanism that is used for.
Background technology
Be used at present internal grinder feeding and compensation mechanism employing as shown in Figure 1 be the wedge leverage, during feeding, at first under oil cylinder 2 ' effect; Make lever 3 ' push down wedge 34 '; Withstand screw mandrel 4 ' end because of lever 3 ' top, force screw mandrel 4 ', nut 41 ' to drive slide plate 5 ' and jump into motion, feeding piston rod 33 ' makes wedge 34 ' move to right under the oil pressure effect then; Because oil cylinder 2 ' is followed lever 3 ', force slide plate 5 ' to realize feed motion; When returning, oil cylinder 2 ' loses oil, and lever breaks away from wedge 34 ' under the effect of return spring 31 ', and the rebound amount is by the 32 ' decision of return screw, and slide plate 5 ' is return under the effect of spring 51 ', and wedge 34 ' moves to left under the feeding piston action simultaneously.What compensation mechanism adopted is three roller type friction clutch modes, and during compensation, under compensating cylinder 9 ' effect, through trundle, roller and big roller 91 ' in the middle of driving change an angle thereby drive screw mandrel 4 ' through spline housing 6 ', realize compensating motion.This feed mechanism because friction pulley skids and causes the accuracy of compensation low, also can't be realized little compensation rate simultaneously because link is many, and the transmission chain length causes feed accuracy low.
The utility model content
In order to overcome the deficiency of prior art, the utility model provides a kind of bearing internal grinder feed compensation mechanism that is used for.
The utility model solves the technical scheme that its technical problem adopted:
A kind of internal grinder feeding and compensation mechanism; Oil cylinder in support, the support, the lever that is connected with oil cylinder, be arranged on the ball screw of lever top, this ball screw is provided with nut, and the ball screw left side is provided with slide plate; Ball screw the right is set with spline housing; This spline housing is connected with shaft coupling, and its middle slide plate is provided with the spring that is connected with support, lever also be provided be connected with support return spring and return screw arranged; Said shaft coupling is provided with servomotor, controls feeding and compensation through servomotor.
In order to make the further raising of the screw mandrel degree of regulation damage of reducing friction simultaneously, said screw mandrel is provided with ball.
The beneficial effect of the utility model is: this compensation mechanism replaces former three roller type friction clutches through servomotor and ball-screw, has improved precision, efficient and the reliability of equipment feeding and compensation when having utilized original structure fully.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the sketch map of original technology;
Fig. 2 is the sketch map of the utility model.
The specific embodiment
With reference to Fig. 2; A kind of internal grinder feeding and compensation mechanism, are arranged on the screw mandrel 4 of lever 3 tops at oil cylinder 2, the lever 3 that is connected with oil cylinder 2 that support 1, support are 1 li, and this screw mandrel 4 is provided with nut 41; Screw mandrel 4 left sides are provided with slide plate 5; Screw mandrel 4 the right are set with spline housing 6, and this spline housing 6 is connected with shaft coupling 7, and its middle slide plate 5 is provided with the spring 51 that is connected with support 1; Lever 3 also be provided be connected with support 1 return spring 31 and return screw 32 arranged, said shaft coupling 7 is provided with servomotor 8.In order to make the further raising of the screw mandrel 4 degrees of regulation damage of reducing friction simultaneously, said screw mandrel 4 is provided with ball.
During feeding; Under the effect of oil cylinder 2; Make lever 3 tops withstand screw mandrel 4 ends, force screw mandrel 4, nut 41 to drive slide plate 5 and realize jumping into, the amount of jumping into is determined by oil cylinder 2 strokes; Slightly, operations such as essence, tarry matter by servomotor 8 rotate, shaft coupling 7 drives spline housings 6 makes screw mandrel 4 rotations, thereby since this moment lever 3 motionlessly force nuts 41 to drive slide plates 5 to realize feedings; When returning, servomotor 8 counter-rotatings make screw mandrel 4 rotations through shaft coupling 7, and the realization feeding is returned under the effect of spring 51, and oil cylinder 2 loses oil, and lever 3 knock-ons under the effect of return spring 31, and the rebound amount is return thereby accomplish by 32 decisions of return screw.Compensating motion is also waited by servomotor 8 and accomplishes, and during compensation, servomotor 8 rotation shaft couplings 7 drive screw mandrels 4 rotations, realizes compensating motions because lever 3 is motionless thereby force nut 41 to drive slide plates 5.
This utility model replaces former three roller type friction clutches through the leading screw 4 of servomotor 8 and band ball, has improved precision, efficient and the reliability of equipment feeding and compensation when having utilized original structure fully.
