Embodiment 1

[0028]The automatic speed-variable double-sided grinding / polishing machine for optical glass screens comprises: a lifting support system (6), an upper grinding system (4), a lower grinding system (2), a box body and a bottom plate (3), an automatic Speed ​​change system (11) is made up of five parts. It is characterized in that: there is an automatic transmission system (11) inside the box body and the bottom plate (3). The main motor is input to the automatic variable speed transmission system through gears. The worker selects different grinding speeds through the thickness of the glass screen, and through the fork mechanism and the synchronizer (19, 13) realizes different helical gear meshes and outputs different speeds to the outer transmission inner sleeve (35), and the outer transmission inner sleeve (35) is respectively connected to the upper The grinding disc drive sleeve (9) is connected to the lower grinding disc support seat (10). Ensure that the upper grinding sys...

Embodiment 2

[0030] According to the automatic speed-variable double-sided grinding / polishing machine for optical glass screens described in Embodiment 1, the automatic speed-variable transmission system includes a fork mechanism and a speed-change mechanism. The shift fork mechanism includes: a swing arm shaft (15), a swing arm (16), a shift fork shaft (18) with interlock pin holes, a first shift fork (14), and a second shift fork (17). The speed change machine includes: input shaft (20), 1st gear acceleration helical gear (21), 2nd gear acceleration helical gear (22), 3rd gear same speed helical gear (23), 4th gear deceleration helical gear (24), 1 / 2 Gear synchronizer (19), 3 / 4 gear synchronizer (13), output shaft (12). The worker selects the grinding speed for glass screens of different thicknesses, and connects the first shift fork (14) or the second shift fork (17) through the swing arm (16). The first shift fork (14) is connected with the 1 / 2 gear synchronizer (19) through the L gro...

Embodiment 3

[0032] According to the double-sided grinding / polishing machine for automatic speed-variable optical glass screens described in Embodiment 1, the lower grinding system includes: an outer transmission inner sleeve (1), a pinion gear transmission connection cover (27), a pinion gear ( 26), upper grinding disc drive sleeve (9), lower grinding disc (2), planetary tooling gear (28), large gear (29), large ring gear support seat (30), lower grinding disc support seat (25), Recovery tank (31). The outer transmission inner sleeve (1) is connected with the variable speed transmission system. The outer transmission inner sleeve (1) transmits power to the pinion gear transmission connection cover (27) and the upper grinding disc drive sleeve (9). The pinion gear transmission connection cover (27) cooperates with the pinion gear (26) to drive the pinion gear (26) to rotate, so that the meshed planetary tooling gear (28) winds around the pinion gear (26) and the bull gear (29) Revolution...

Abstract

The invention relates to a double-sided grinding / polishing machine with an automatic speed-changing function, for an optical glass screen. With the emerging of glass screens with radians, the thin parts of arc edges are easily broken due to large relative movement between grinding discs and level parts are insufficiently grinded in the case of a low speed, of the traditional polishing. Therefore,the invention discloses a grinding / polishing machine with an automatic speed-changing function, with regard to an optical sheet glass screen. The double-sided grinding / polishing machine disclosed by the invention comprises a box body (3), wherein an automatic speed-changing transmission system (11) is arranged in the box body (3); the automatic speed-changing transmission system is connected withan outer transmission inner sleeve (1); and the outer transmission inner sleeve is connected with an upper grinding disc drive sleeve (9) and a lower grinding disc drive sleeve (10) separately to complete power transmission, so that an upper grinding system and a lower grinding system can oppositely run at a certain speed ratio. A lifting support system (6) is installed on the box body and used for realizing a lifting function. The double-sided grinding / polishing machine disclosed by the invention is used for double-sided grinding / polishing for the optical glass screen through the five parts of the lifting support system (6), the upper grinding system (4), the lower grinding system (2) and the automatic speed-changing transmission system (11).

Description

technical field [0001] The patent of the present invention relates to the field of polishing machines, in particular to an automatic speed-variable double-sided grinding / polishing machine for optical glass screens. Background technique [0002] In recent years, with the rapid development of smartphones, people are unwilling to settle for a black rectangular all-glass and metal body. Because 2.5D screens and 3D screens are a kind of curved screens, a plane is displayed in the middle and a certain curvature is displayed on the edge, so that the edge looks like a drop-like visual effect, and they are widely used and promoted. Optical glass has high hardness and high brittleness, so it is very difficult to grind and polish both sides of the optical glass screen. At present, the traditional polishing machine is used in the actual production and processing process, which is not only complicated in structure, difficult to maintain, but also untargeted because of the traditional po...
