Abstract

The utility model relates to a corner mechanism for a glass straight bevel edge grinding machine, which is composed of a rotary arm, a corner base and a support plate for a grinding wheel seat, wherein one end of the rotary arm is provided with a concave arc notch, and a rotary center is in superposition with the center of the end surface of a grinding wheel. The corner mechanism has compact structure, and can easily realize the automatic control of the length of the bevel edge of glass to grind.

Description

Corner mechanism for glass edge grinding machine

The utility model relates to a kind of glass edge-grinding machine, particularly the rotation angle mechanism of straight line hypotenuse edge polisher.

The cursor shape of original glass linear hypotenuse edge polisher rotation angle mechanism as shown in Figure 3.Its end face is a convex.Transmit in order not influence glass, the centre of gyration A of cursor 1 must be lower than emery wheel end face center O.When cursor turns over angle [alpha], the displacement of emery wheel end face center O, promptly the amount of feeding of planker is S '.The shortcoming of the rotation angle mechanism of this structure is: 1. the amount of feeding of planker is bigger, and structure is not compact; 2. the movement locus of emery wheel end face center O is a camber line, and the relation of hypotenuse length L and S ', α is difficult to be determined, therefore is difficult to realize automatic control.

The purpose of this utility model is to overcome above-mentioned defective of the prior art, provides a kind of planker amount of feeding little, and is easy to the hypotenuse length that is ground glass is realized the glass linear hypotenuse edge polisher rotation angle mechanism of control automatically.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a cursor working state figure of the present utility model;

Fig. 3 is the cursor working state figure of original rotation angle mechanism.

Below in conjunction with accompanying drawing the technical solution of the utility model and operation principle are illustrated.

With reference to Fig. 1, Fig. 2, this glass linear hypotenuse edge polisher rotation angle mechanism is made up of cursor 1, corner pedestal 2, emery wheel seat planker 3.Cursor 1 and bistrique assembly 4 all are fixed on the corner pedestal 2, and the three can rotate simultaneously.The effect of planker 3 is to adjust the horizontal feed of bistrique apart from S.Under the effect of cursor 1 at actuating unit, when being centre of gyration swing set angle α with the A point, the bistrique end face also rotates same angle [alpha], the glass grinding angle [alpha] that obtains requiring.The utility model is made the arcs of recesses breach with an end of cursor 1, and the centre of gyration A of cursor 1 is overlapped with emery wheel end face center O.Like this, hypotenuse length L and α, S meet relational expression Sin α=S/L.When α one regularly, by regulating the L that amount of feeding S just can obtain requiring, thereby be convenient to realize automatic control.Comparison diagram 2, Fig. 3 as can be seen, under the grinding angle α situation identical with the hypotenuse length L, the amount of feeding S of the utility model planker 3 is than the amount of feeding S ' weak point of the planker 3 of original structure.

The utility model has the advantages that: simple in structure, practical, not only be easy to the hypotenuse length that control automatically is ground glass, and planker adjustment stroke is short, the rotation angle mechanism compact conformation, thus can reduce the volume of putting in order the table glass edge polisher.

Claims

1, a kind of rotation angle mechanism of glass linear hypotenuse edge polisher, form by cursor (1), corner pedestal (2), emery wheel seat planker (3), it is characterized in that: an end of cursor 1 is made the arcs of recesses breach, and the centre of gyration A of cursor overlaps with emery wheel end face center O.
