Abstract
A device for grinding medium and high curves, curves with the CVC (continuously-variable convexity) and optional curves for a roll grinder is mounted in a grinding frame, a grinding wheel (1) is disposed at the front of an upper shell (2) of the grinding frame, a roller (12) is connected onto a roller seat (13) by a rotating shaft (14) and fixed into the upper shell (2) of the grinding frame, and a bearing block (8), a linear rolling guide rail (9) and a support (10) are respectively mounted on the top of a lower shell (11) of the grinding frame. A ball screw (3) is driven to rotate by a motor (6) via a speed reducer (7), a sliding inclined block (4) is driven to slide linearly along the rolling guide rail (9) back and forth, the upper shell (2) of the grinding frame swings vertically around an O point due to movement of the sliding inclined block (4), accordingly, the grinding wheel (1) advances or retracts, and requirements of the roll grinder to grinding the medium and high curves, the curves with the CVC and the optional curves are met. The device is simple in structure and convenient in installation and adjustment, and grinding precision of curved workpieces can be improved.
Description
Technical field: the utility model relates to the camber grinding device of CNC roll grinder, particularly a kind of device that is used for the high curve of roll grinder grinding, CVC curve and arbitrary curve.
Background technology: high grinding has three kinds of forms in the prior art: 1), through high change gear in the planker gear driven, in high cam, in high leverage the mill frame is kowtowed realize.This mechanism driving chain length, low, the control poor sensitivity of the big grinding accuracy of drive gap.2), make lever swing realize grinding frame and kowtow high grinding in carrying out through servomotor drive worm gear, worm screw, ball screw rotation.This mechanism is high to installation requirement, when worm gear, worm screw gap adjustment more complicated, grinding in a large amount inaccurate.3), eccentric bushing is realized the forward-reverse of emery wheel.This mechanism is high to the processing request of eccentric bushing, and corresponding cost is higher.
Summary of the invention: the purpose of the utility model is to provide a kind of device that is used for the high curve of roll grinder grinding, CVC curve and arbitrary curve; This device transmission is simple, be convenient to control, the slip through skewback realizes grinding frame and kowtows, and carries out the grinding of arbitrary curve.Can improve the degree of accuracy of camber grinding.
The formation of the utility model: a kind of device that is used for the high curve of roll grinder grinding, CVC curve and arbitrary curve; Form by emery wheel, mill frame upper shell, ball screw, slip skewback, shaft coupling, motor, reductor, bearing block, linear rolling track, bearing, mill frame lower house, roller, roller mount and gyroaxis; This device is installed in the mill frame, and emery wheel places mill frame upper shell anterior, and roller is connected on the roller mount through gyroaxis; And be fixed in the mill frame upper shell; Bearing block, linear rolling track, bearing are installed in the end face of mill frame lower house respectively, and motor is connected with ball screw through shaft coupling through reductor, and ball screw is enclosed within the slip skewback; And cooperate with the slip skewback, the slip skewback is arranged on the linear rolling track.
Motor drives the ball screw revolution through reductor; Ordering about the slip skewback slides before and after linear rolling track; Moving of slip skewback; Mill frame upper shell is swung up and down around O point, thereby the realization emery wheel advance or retreat, and satisfies the grinding of the high curve of roll grinder centering, CVC curve and arbitrary curve to the forerunner.
Roller slides along slip skewback inclined-plane, and the angle on inclined-plane has determined mill frame upper shell rotating a certain amount of around the O point, the forerunner of emery wheel or retreat the grinding that realizes the high curve of centering, CVC curve and arbitrary curve.
Compared with prior art, the utlity model has following characteristics: with high simplification the in the machinery of complex original; Processing intensity and installation period are saved in installation and easy to adjust, improve the grinding accuracy of curve workpiece.
Description of drawings: Fig. 1 is the utility model structural representation, and Fig. 2 is the A-A cutaway view of Fig. 1.
Among the figure 1, emery wheel, 2, mill frame upper shell, 3, ball screw, 4, the slip skewback, 5, shaft coupling; 6, motor, 7, reductor, 8, bearing block, 9, linear rolling track, 10, bearing; 11, mill frame lower house, 12, roller, 13, roller mount, 14, gyroaxis.
The specific embodiment: like Fig. 1, shown in Figure 2; The utility model is made up of emery wheel, mill frame upper shell, ball screw, slip skewback, shaft coupling, motor, reductor, bearing block, linear rolling track, bearing, mill frame lower house, roller, roller mount and gyroaxis; This device is installed in the mill frame, and emery wheel 1 places mill frame upper shell 2 front portions, and roller 12 is connected on the roller mount 13 through gyroaxis 14; And be fixed in the mill frame upper shell 2; Bearing block 8, linear rolling track 9, bearing 10 are installed in the end face of mill frame lower house 11 respectively, and motor 6 is connected with ball screw 3 through shaft coupling 5 through reductor 7, and ball screw 3 is enclosed within the slip skewback 4; And cooperate with the slip skewback, slip skewback 4 is arranged on the linear rolling track 9.
Motor 6 drives ball screw 3 revolutions through reductor 7; Ordering about slip skewback 4 slides along linear rolling track 9 front and back; Moving of slip skewback 4; Mill frame upper shell 2 is swung up and down around O point, thereby realization emery wheel 1 advance or retreat, and satisfies the grinding of the high curve of roll grinder centering, CVC curve and arbitrary curve to the forerunner.
Roller slides along slip skewback inclined-plane, and the angle on inclined-plane has determined mill frame upper shell rotating a certain amount of around the O point, the forerunner of emery wheel or retreat the grinding that realizes the high curve of centering, CVC curve and arbitrary curve.
