[0045] like Figure 1 As shown, the present application provides a glass grinding machine, comprising:

[0046] A workbench frame 10, on which a gantry beam assembly 11 and a power distribution cabinet 12 are fixed, and the power distribution cabinet 12 is used to supply power to the entire glass grinding machine;

[0047] A lower grinding disc assembly 9 rotatably disposed on the workbench frame 10, and the lower grinding disc assembly 9 is located directly below the gantry crossbeam assembly 11;

[0048] An upper grinding disc assembly 7 adapted to the lower grinding disc assembly 9, the upper grinding disc assembly 7 is arranged above the lower grinding disc assembly 9 so as to be movable up and down by a lifting cylinder 8, and the lifting cylinder 8 is fixed on the gantry crossbeam assembly 11;

[0049] A plurality of vertical suspension devices 6 for locking and fixing the second grinding disc 13 of the upper grinding disc assembly 7 are also fixed on the gantry crossbeam assembly 11 .

[0050] By setting the upper grinding disc assembly 7 as a structure that can move up and down, the upper and lower grinding disc assemblies of the glass grinder can be quickly separated, and the glass that has been ground can be removed without manual operation, thereby improving production safety. After the upper grinding disc assembly 7 moves to a preset height, the upper grinding disc assembly 7 is locked and fixed by the vertical suspension device 6 to support the upper grinding disc assembly 7. On the one hand, it prevents the upper grinding disc assembly 7 from falling due to a malfunction and ensures the safety of the operator. On the other hand, it can avoid the problem of the lifting cylinder 8 being damaged by the gravity of the upper grinding disc assembly 7 for a long time, thereby ensuring the service life of the lifting cylinder 8, solving the problem of frequent replacement of the lifting cylinder 8, ensuring production efficiency, and reducing production costs.

[0051] In some embodiments, any vertical suspension device 6 comprises:

[0052] A fixed seat 1, fixed on the gantry beam assembly 11;

[0053] A rotary cylinder 2 is fixed on a fixed seat 1, and an output end of the rotary cylinder 2 is connected to a load-bearing shaft 4, and the load-bearing shaft 4 is connected to the bearing in the form of a shaft shoulder and a retaining spring;

[0054] One end of the load-bearing shaft 4 passing through the bearing seat 3 is connected with a clamping block 5 .

[0055] The fixing seat 1 of the vertical suspension device 6 is fixed on the gantry beam assembly 11, and the other components are facing the upper grinding disc assembly 7, so that the vertical suspension device 6 is inverted, and the clamping block 5 is driven to rotate through the load-bearing shaft 4 by the rotating cylinder 2, so that the upper grinding disc assembly 7 is clamped in the position between multiple clamping blocks 5. When the upper grinding disc assembly 7 is working, the clamping block 5 is rotated to the outer part of the upper grinding disc assembly 7 through the rotating cylinder 2. During the upward movement of the upper grinding disc assembly 7, no interference will occur, thereby improving the safe operation of the glass grinder and ensuring stability.

[0056] Among them, different specifications of the rotary cylinder 2 can be selected according to the actual torque of the application, and the rotation angle of the cylinder can be adjusted. Since the force on the vertical suspension device 6 is mainly the gravity of the suspended object, the torque of the rotary cylinder 2 to overcome the friction on the bearing is small, so the rotary cylinder 2 of general specifications can drive the rotation;

[0057] In some embodiments, a pair of tapered roller bearings are disposed in the bearing seat 3, and the paired tapered roller bearings are arranged in an upper and lower array. By selecting the paired tapered roller bearings to be arranged upper and lower, rotational support can be provided while withstanding a larger axial force.

[0058] In some embodiments, the load-bearing shaft 4 and the block 5 are key-connected, which is conducive to transmitting torque. A locking nut for locking the block 5 is provided at the end of the load-bearing shaft 4, which is easier to process, install and disassemble than welding.

[0059] In some embodiments, the lower grinding wheel assembly 9 includes a first grinding wheel 18, an outer gear ring 17 arranged on the outer ring of the first grinding wheel 18, and an inner gear ring 19 arranged on the inner ring of the first grinding wheel 18. A workpiece fixture 21 for placing and mounting a plurality of glasses to be ground is formed between the outer gear ring 17 and the inner gear ring 19. The inner gear ring 19 and the outer gear ring 17 rotate in opposite directions.

[0060] In some embodiments, it also includes:

[0061] The driving system 20 is used to drive the first grinding disc 18 to rotate and / or move up and down. By driving the first grinding disc 18 to move up and down, the pressure applied to the glass to be ground can be adjusted.

[0062] In some embodiments, the workpiece fixture 21 is a planetary gear structure, adapted to the size of the first grinding disc 18 , and a plurality of glasses to be ground are installed in the installation groove 22 on the surface of the workpiece fixture 21 .

[0063] During grinding, the workpiece fixture 21 is placed on the first grinding disc 18 so that the workpiece fixture 21 meshes with the outer gear ring 17 and the inner gear ring 19. The workpiece fixture 21 acts as a planetary wheel, which rotates and revolves with the outer ring during grinding. When the grinding glass is placed in the fixture, the upper grinding disc is pressed down onto the workpiece fixture 21 by the cylinder to start grinding. That is, when the rotation speeds of the inner gear ring 19 and the outer gear ring 17 are different, the workpiece fixture 21 can rotate along the axis of the workpiece fixture 21 and along the axis of the first grinding disc 18.

[0064] In some embodiments, the upper grinding disc assembly 7 includes a second grinding disc 13, a grinding liquid pipe 14, and a grinding liquid tank 16 disposed above the second grinding disc 13;

[0065] A plurality of grinding liquid tubes 14 are arranged in a circular array above the second grinding disc 13 . The head end of any grinding liquid tube 14 is connected to the grinding liquid tank 16 , and the tail end is arranged above the second grinding disc 13 and close to the outer circumference.

[0066] During grinding, the grinding liquid is added into the grinding liquid tank 16 and flows to the second grinding disc 13 through the grinding liquid pipe 14. The second grinding disc 13 may be provided with a through hole. The grinding liquid flows through the through hole to between the second grinding disc 13 and the first grinding disc 18, thereby achieving the effect of cooling and dust reduction.

[0067] In some embodiments, the upper grinding disc assembly 7 further includes an intermediate support disc 15 disposed between the second grinding disc 13 and the grinding liquid tank 16, and the intermediate support disc 15 is connected and fixed to the second grinding disc 13 via a column;

[0068] Any grinding liquid tube 14 passes through the middle support plate 15 , so as to position and fix the grinding liquid tube 14 , thereby improving the stability of the upper grinding disc assembly 7 .

[0069] In some embodiments, the tapered roller bearing is fixed by a bearing gland, a retaining spring, and a bushing.

[0070] The working process of this application is as follows:

[0071] When a batch of glass to be ground is finished, the lifting cylinder 8 is controlled to lift the second grinding disc 13 and / or the upper grinding disc assembly 7. When the lifting cylinder 8 is lifted to the preset position, the rotating cylinder 2 of the vertical suspension device 6 is controlled to rotate 90° or 180° (specifically adjusted according to the initial position of the clamping block 5), driving the clamping block 5 to clamp into the bottom of the second grinding disc 13, and fix the second grinding disc 13 and / or the upper grinding disc assembly 7. When the operator finishes loading (changing the glass to be ground), before the lifting cylinder 8 is activated, the vertical suspension device 6 is disengaged, and the second grinding disc 13 and / or the upper grinding disc assembly 7 are lowered for grinding.

[0072] Among them, a magnetic switch can be configured on the lifting cylinder 8. After the magnetic switch detects that it is in place, a signal is given to the rotating cylinder 2 of the vertical suspension device 6 to control the rotating cylinder 2 to rotate at a preset angle.
