SU751587A1 - Apparatus for working sheet glass edge - Google Patents

Description

replacement part for each glass measure. For proper orientation of the glass sheet 17 on each table there are two stops 18. To the table there is a copier 19 consisting of two halves. Copier corresponds to the specified shape of the glass sheet. Therefore, just like the desktop, the copier is a smith detail.

The drive of rotation 5 of the working table consists of an elactodzigatel of direct current 20, a worm gear reducer 2 /, a planetary gear reducer 22, a bevel gear 23 (Fig. 6) and a cylindrical 24 pair. Speed is swerf; table 4 within one revolution, 3 depending on the configuration and size of the removal of glass allowances, is not consistent. A change in the program defined by the fist acting on the generator of the thyristor converter of the direct current electric motor 20, the speed B (reducing the supplying layer of the glass sheet to the processing tool and efficiently. with a sheet of glass 17 in the vertical direction relative to the grinding point 11. For this purpose, an oscillating drive 5 is used, which consists of an electric wire ate current non-belt 25, klnnoremennoy transmission 26 (FIG. I), 27 and worm screw. couples (FIG. 3). Ostsillirevanie is accomplished by reversing elektrodvngatel 25.

.ok 13 is installed on the shaft 29 and kinematically connected through a cable drive 14 (fig. 3 | through a cardan 30 and a conical pair 31 to G riv BOD: m 1 switch on the desktop 5. To turn the cam on and off .ivcMOTpeiia clutch 32, operating from pneumozdra 33. to the leaf gap of the stbl sheet corresponds to its loflle Kvlachka, FULLY, so that, ragstg;); the corresponding point is on the e-file. Grinding jo,:; 3x 1-1 (fig. 5) - contains ilst ;; mind - 34, lasazalny on the shaft 55, provided with a sealed, sealed, particularly point): I connected the peaks. Grinding: -Teil // and tapered zolik 36, the axis of which combines with the axis of the head, placed 3 guides 1x 37 and 38. Screws 39 and 40 serve to adjust the grinding head // and 1colic roller 36 in the vertical direction. The rotation of the grinding head headpiece is performed by a // water drive (Fig. 1), consisting of an electric motor 42 and a flat-time transmission 43.

The device works as follows.

A sheet of glass 17 is installed on the desktop 4, its orientation relative to

two stops 18. After clamping the sheet on the table with the cylinder 16, Ulo.ry 18 is removed. The grinding head 41 is turned on. A grinding head // with tool 34 is supplied to the end of the sheet by means of pneumatic cylinder 15. When you hit the glass of the locomotive of the roller 36 with the table copier 19, the tool lowers the glass layer by the amount of lirusk. On It counts the drive of the table rotation 5 and oscillating drive

6. For one revolution of the table with a sheet of glass, the cam 13 mechaliz.ma loddarzhali. The pressure angle of the tool 12 also performs one revolution. At the same time, the bumpy lever 7, controlled by the cam 13 to the track

Behind the contour of the glass to be machined 17, the Lostolisto is applied to the pressure of the tool 34 on the LZ-KT glass.

The presence of a long arm 8 with a contact roller 9, interacting with the edge of the mechanism of pressure of the tool 12, the edge of the glass sheet 17, improves the quality of processing and expands the range of the processed items.

Claims (2)

Claim 1. A device for processing the edge of a sheet of glass, comprising a pivot arm with a grinding head and a drive of rotation and a mechanism for maintaining a constant angle of pressure and a tool on the edge of the sheet, with the exception that to improve the quality of processing and r a rs a ness with glass processing, the device is equipped with an additional lever with a contact roller, on which a lever with a grinding wheel is pivotally mounted the head, and the mechanism for maintaining the constancy of the pressure angle of the instrument is made in the form of a kul ball with a rotation drive, installed with the possibility of interaction with the. roller. 2. The device according to claim 1, characterized in that the distance from the center of the cam to each individual point of its profile is inversely proportional to the distance from the center of the glass sheet to the corresponding point on its edge.
