Abstract
A grinding head module for wire-drawing die grinder is composed of grinding needle and its fixture, vibration motor for making the grinding needle to vibrate up and down, eccentric axle driven by said vibration motor, and driving part.
Description
Technical field
The present invention relates to a kind of grinding head assembly of grinder of energy grinding work-piece endoporus.
Background technology
The workpiece particularly endoporus of wire drawing die is made up of two parts, and the one, cylindrical hole, another is a round taper hole, its requirement on machining accuracy is very high, the tolerance of physical dimension is the some thousandths of millimeter, and surface smoothness requires high, and the coherence request of producing in batches is also very harsh.The bistrique part of conventional grinder is rotated at a high speed by card grinding driven by motor card grinding chuck and card grinding, and hand rest wire drawing die body grinds.This processing method not only speed is slow, and can not ensure the quality of products.
Summary of the invention
The invention provides a kind of grinding head assembly of grinder, card grinding can improve grinding rate, and guarantee Grinding Quality with respect to the upper and lower vibration of workpiece.
Technical scheme of the present invention is as follows: a kind of grinding head assembly of grinder, it comprises card grinding, the card grinding chuck, vibrating motor, eccentric shaft and driving member, the output shaft of vibrating motor connects with eccentric shaft, eccentric shaft is connected with the card grinding chuck by driving member, it is characterized in that it also is provided with card grinding motor and turning cylinder, the card grinding motor is connected with the card grinding chuck, described driving member is a card grinding motor fixing frame and last, the lower spring sheet, the card grinding motor fixing frame is solidly set on outside the card grinding motor, eccentric shaft connects with the card grinding motor fixing frame, turning cylinder is parallel with the card grinding motor fixing frame, the turning cylinder two ends are provided with, lower roof plate, card grinding motor fixing frame and last, pass through last between the lower roof plate, the lower spring sheet connects.
The lower roof plate that the present invention is connected with turning cylinder is provided with the deflection adjustable plate, the both sides of deflection adjustable plate are provided with adjusting screw(rod), described eccentric shaft is installed in the slotted eye of rotating turret by bearing, the tail end of rotating turret is fixed on the grinding frame and can rotates around grinding frame, the middle part of rotating turret is connected with the card grinding motor fixing frame by bearing pin, and bearing pin is supported by the bearing in the slotted eye on the card grinding motor fixing frame.
The present invention can the situation of high speed rotating design under the drive of workseat at workpiece to be processed, its operation principle is as follows: (one) grinding head assembly is not established the card grinding motor: vibrating motor drives eccentric shaft and rotates, eccentric shaft converts the vibration of connecting axle to by drive link, upper and lower spring leaf, connecting axle drives the upper and lower double vibrations of card grinding, its amplitude is constant, and vibration frequency can change by the rotating speed of regulating vibrating motor.At this moment Work piece high-speed rotation on the one hand, the card grinding up-down vibration has increased both relative motions on the one hand, has improved grinding rate, can grind wire drawing die cylindrical bore part.(2) grinding head assembly is provided with the card grinding motor: vibrating motor rotates, convert the beat of eccentric shaft to by eccentric shaft, the beat of eccentric shaft is by the card grinding motor fixing frame, spring leaf converts the up-down vibration of card grinding to up and down, its amplitude is constant, and vibration frequency can change by the rotating speed of regulating vibrating motor; Card grinding driven by motor card grinding rotates at a high speed; The lower roof plate that is connected with turning cylinder is provided with the deflection adjustable plate, the both sides of deflection adjustable plate are provided with adjusting screw(rod), can promote the deflection adjustable plate moving axis that rotates and rotate by rotating adjusting screw(rod) like this, it is that axis deflects with the turning cylinder that drive makes upper and lower spring leaf, make the vertical axis skew of the vertical axis and the workpiece of card grinding, form the monolateral grinding of card grinding workpiece.The shape of workpiece endoporus, precision depend on the size of card grinding, after the card grinding wearing and tearing, can adjust the deflection of upper and lower spring leaf workpiece is carried out the monolithic grinding, to reach needed size, can grind wire drawing die tapered bore part.When being provided with the card grinding motor, card grinding, workpiece be high-speed motion simultaneously, interacts, and has further improved grinding rate.
Beneficial effect of the present invention: increased the relative motion between card grinding and the workpiece, improved grinding rate, and guaranteed Grinding Quality.

The specific embodiment
The grinding head assembly of grinder, it comprises card grinding 6, card grinding chuck 5, vibrating motor 9, eccentric shaft 1, driving member, and the output shaft of vibrating motor 9 connects with eccentric shaft 1, and eccentric shaft 1 is connected with card grinding chuck 5 by driving member.
According to shown in Figure 1, vibrating motor 9 drives transition axises 7 by driving-belt 8 and rotates, and transition axis 7 and eccentric shaft 1 connect by shaft coupling.Described driving member is drive link 3 and upper spring sheet 2, lower spring sheet 4, drive link 3 connects with eccentric shaft 1, and two spring leafs are fixed on the two ends of drive link 3, is provided with connecting axle 10 between two spring leafs, connecting axle 10 is connected and fixed with card grinding chuck 5, and card grinding 6 is fixed on the card grinding chuck 5.
According to Fig. 2, shown in Figure 3, card grinding motor 11 is connected with card grinding chuck 5, and card grinding 6 is fixed on the card grinding chuck 5.Described driving member is card grinding motor fixing frame 13 and upper spring sheet 2, lower spring sheet 4, and card grinding motor fixing frame 13 is solidly set on outside the card grinding motor 11.The output shaft of vibrating motor 9 connects with eccentric shaft 1, the other end of eccentric shaft 1 is installed in the slotted eye of rotating turret 15 by the bearing supporting, the tail end of rotating turret 15 is installed on the grinding frame and can rotates around grinding frame, the middle part of rotating turret 15 is connected with card grinding motor fixing frame 13 by bearing pin, and bearing pin is supported by the bearing in the slotted eye on the card grinding motor fixing frame 13.Parallel with card grinding motor fixing frame 13 and to be provided with turning cylinder 12, turning cylinder 12 is installed in the axle bed by bearing, and axle bed is fixed on and grinds on the frame.Turning cylinder 12 two ends are provided with upper and lower top board, are connected by upper and lower spring leaf between card grinding motor fixing frame 13 and the upper and lower top board.Be fixed with deflection adjustable plate 14 on the lower roof plate that turning cylinder 12 is connected, deflection adjustable plate 14 both sides are provided with adjusting screw(rod), adjusting screw(rod) passes the through hole that grinds on the frame, tail end withstands deflection adjustable plate 14.Upper and lower spring leaf drives card grinding 6 moving axis 12 deflections that can rotate, and its amount of deflection is regulated by adjusting screw(rod), regulates the vertical axis that card grinding departs from workpiece, forms the monolateral grinding of card grinding to workpiece.
