[0021] The present invention will be further described below in conjunction with the accompanying drawings.
[0022] like Figure 1 , Figure 2 , Figure 3 As shown, an embodiment of the present invention is a magnetic suspension optical glass secondary pressing molding machine, including a loading and unloading material handling robot and a turntable worktable group, a magnetic suspension bearing group that can suspend the turntable worktable group, a frame 1 for installing the magnetic suspension bearing group, and a rotating mechanism for driving the turntable worktable group to rotate.
[0023] The turntable workbench assembly includes a turntable 2, a mold 3, a rotating shaft 4 and a motor bracket 5. The lower surface of the turntable 2 is provided with a rotating shaft mounting countersunk hole, and the upper surface is provided with a rotating shaft screw mounting through hole. The upper end surface and cylindrical surface of the rotating shaft 4 are installed in the rotating shaft mounting countersunk hole of the turntable 2 by screws. The upper surface of the turntable 2 is provided with a mold mounting countersunk hole, and the mold mounting countersunk hole wall is provided with a mold mounting thread. The lower cylindrical surface of the mold 3 is provided with a mold thread. The mold 3 is installed in the mold mounting countersunk hole on the upper surface of the turntable 2 through the mold thread connection. There are 6 groups of molds 3, which are evenly installed on the upper surface of the turntable 2, such as Figure 2 A motor bracket mounting hole is provided on the cylindrical surface of the rotating shaft 4, and the motor bracket 5 is mounted on the rotating shaft 4 by bolts.
[0024] The frame 1 is a hollow barrel-shaped structure, and the inner side wall can be used to install the magnetic suspension bearing group. The side wall of the frame 1 is provided with an annular through groove that is rotatably matched with the motor bracket 5.
[0025] The magnetic suspension bearing group includes an axial magnetic suspension bearing 6 and a radial magnetic suspension bearing 7. The frame 1 is provided with an axial magnetic suspension bearing mounting hole. There is a group of axial magnetic suspension bearings 6, a total of 4, which are evenly installed on the frame 1 by screws. The rotating shaft 4 is a stepped shaft with a thick middle and thin ends, forming a circular boss. The circular boss cooperates with the axial magnetic suspension bearing 6. There is a gap between the axial magnetic suspension bearing 6 and the circular boss of the rotating shaft 4. The circular boss of the rotating shaft 4 can rotate freely in the middle of the axial magnetic suspension bearing 6, such as Figure 1 The frame 1 is provided with radial magnetic bearing mounting holes, and there are two groups of radial magnetic bearings 7, each group of 8, which are evenly installed on the frame 1 by screws. There is a gap between the radial magnetic bearings 7 and the rotating shaft 4, and the rotating shaft 4 can rotate freely in the middle of the radial magnetic bearings 7, as shown in FIG. Figure 1 and Figure 3 shown.
[0026] The rotating mechanism includes a large bevel gear 8, a small bevel gear 9 and a motor 10. Among them, the large bevel gear 8 is provided with a large bevel gear mounting hole, and the large bevel gear 8 is mounted on the rotating shaft 4 through a key. The small bevel gear 9 is provided with a small bevel gear mounting hole, and the small bevel gear 9 is mounted on the motor shaft of the motor 10 through a key, and the small bevel gear 9 is meshed with the large bevel gear 8. The motor 10 and the motor bracket 5 are provided with motor mounting holes, and the motor 10 is mounted on the motor bracket 5 by screws to ensure that the motor 10 rotates with the rotating shaft 4 during production and has a fixed relative position with the large bevel gear 8. In this way, the problem of the change of the gap between the bevel gear teeth due to the flexible concession caused by the axial magnetic suspension bearing 6 under positive pressure during pressing is avoided, thereby avoiding the actual problems of bonding between teeth and bending of the motor shaft.
[0027] The loading and unloading handling robot 11 is a common non-standard 4-DOF robot, and the 4 DOFs are: rotational freedom around the x-axis, displacement freedom along the y-axis, displacement freedom along the z-axis, and rotational freedom around the z-axis. The loading and unloading handling robot 11 is composed of a base, a rotating body, a built-in lifting mechanism, an articulated bracket, a lifting cylinder, a working cylinder, and a clamping mechanism. Among them, the robot base is installed on the ground by expansion bolts, the built-in lifting mechanism is installed on the base by bolts, the rotating body is installed on the built-in lifting mechanism by bearings, the articulated bracket is installed on the rotating body by bolts, the lifting cylinder is installed on the rotating body by hinges, the working cylinder is installed on the lifting cylinder and the articulated bracket by hinges, and the clamping mechanism is installed on the working cylinder by screws.
[0028] During production, the loading and unloading handling robot 11 places the glass blank to be pressed in the mold 3. After the pressing, the motor 10 is powered on to drive the small bevel gear 9 to rotate, and then drives the large bevel gear 8 to rotate through gear meshing, and then drives the rotating shaft 4 to rotate, and then drives the turntable 2 and the upper mold 3 to rotate, so as to realize the station change. The rotating shaft 4 can make a 360° continuous rotation in the same direction, or it can make a reciprocating rotation in a specified sector area according to the process design requirements. When the pressed molded part is transferred to the discharge position, the loading and unloading handling robot 11 takes out the pressed molded part. Repeat the above process.
[0029] During production, the motor 10 rotates along with the rotating shaft 4 .
[0030] The invention has the characteristics of high automation, convenient operation and low failure rate, and is mainly used for the production of optical glass secondary molded parts with medium and large diameters and special shapes.
