Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0030] See also Figure 1 - Figure 4 The utility model provides a special glass trimming machine, comprising: a base 1 and a workbench 2 rotatably connected to the top thereof and having a T-shaped cross section, wherein the base 1 is provided with a rotating grinding mechanism for trimming the glass;

[0031] A plurality of suction cups 8 fixedly mounted on the top of the workbench 2;

[0032] A protective shell 3 is slidably connected to the top of the base 1 through a guide rail, and an observation window is provided on one side of the protective shell 3. A handle is installed on one side of the protective shell 3 and located on the side of the observation window;

[0033] A connecting block 4 is fixedly mounted on one side of the protective shell 3, and a slot is provided on the connecting block 4;

[0034] A mounting plate 5 fixedly mounted on one side of the top of the base 1;

[0035] A fixing block 6 fixedly mounted on one side of the mounting plate 5 and having a hollow interior;

[0036] A trapezoidal block 7 is slidably connected to one end of the fixed block 6 and is engaged with the slot;

[0037] And an elastic mechanism is arranged in the fixed block 6 and connected to the trapezoidal block 7. When the trapezoidal block 7 is subjected to force, it is extended and retracted through the elastic mechanism so that the trapezoidal block 7 extends into or out of the slot.

[0038] The elastic mechanism includes a movable rod 9 that is slidably connected to the other end of the fixed block 6, a spring 10 that is sleeved on the surface of the movable rod 9, and a pulling block 11 that is fixedly connected to one end of the movable rod 9. The trapezoidal block 7 is connected to the movable rod 9, and the two ends of the spring 10 are respectively connected to the fixed block 6 and the trapezoidal block 7.

[0039] The technical solution provided by this embodiment is as follows: when in use, the circular glass workpiece is placed on the workbench 2 and fixed by the suction cup 8, and then the protective shell 3 is pulled along the guide rail by holding the handle to make it contact and close with the mounting plate 5, so that the protective shell 3 covers the grinding and trimming area. During the movement of the protective shell 3, the connecting block 4 can be driven to move synchronously, so that the connecting block 4 contacts and squeezes the trapezoidal block 7, thereby using the inclined surface of the trapezoidal block 7 to guide it to the inside of the fixed block 6 to contract the squeezing spring 10, and at the same time drive the movable rod 9 to slide. When the protective shell 3 contacts and closes with the mounting plate 5, the trapezoidal block 7 is aligned with the card slot, so that the spring 10 Under the action of the elastic force, the trapezoidal block 7 is driven to reset and engage with the slot, so as to limit and fix the protective shell 3, so that it covers the processing area to isolate the debris and dust generated by the processing. On the contrary, when the protective shell 3 is opened, the trapezoidal block 7 can be separated from the slot by moving the pulling block 11 through the movable rod 9. Therefore, the effect of protecting the staff is achieved, and the dust and debris splashing to avoid harm to the staff is avoided, thereby ensuring the quality of the working environment and the operating safety of the personnel, effectively improving the safety of use and processing efficiency. Finally, the glass work can be trimmed by rotating the grinding mechanism, and the processing status can be viewed through the observation window.

[0040] Furthermore, a positioning mechanism for centering the glass workpiece is provided on the mounting plate 5 .

[0041] The positioning mechanism includes a threaded sleeve 12 that is rotatably connected to the mounting plate 5, a screw 13 that is threadedly connected to the threaded sleeve 12, an arc-shaped limit seat 14 that is fixedly connected to one end of the screw 13, and a plurality of limit rollers 15 that are rotatably connected to the inner arc surface of the arc-shaped limit seat 14. A groove is provided on the surface of the screw 13, and a scale line is provided in the groove. An indicator needle 16 that matches the scale line is fixedly installed on one side of the mounting plate 5.

[0042] Specifically, when fixing the glass workpiece, according to the diameter of the circular glass, the threaded sleeve 12 is rotated to drive the screw 13 therein to extend, and drive the arc-shaped limit seat 14 to move toward the center of the workbench 2. At the same time, the scale line and the indicator needle 16 are used to make the distance from the limit roller 15 in the middle of the arc-shaped limit seat 14 to the center of the workbench 2 consistent with the diameter of the circular glass. Then, the circular glass is placed on the suction cup 8, and the suction cup 8 adsorbs and fixes it, and the edge of the glass is brought into contact with the limit roller 15, thereby achieving the effect of centering and fixing the glass workpiece, making it easier to fix the glass in the center of the workbench 2, which is beneficial to improving the effect of glass processing and trimming.

[0044] Specifically, during trimming, the linear module 19 drives the fixed frame 20 to move and adjust, so as to drive the grinding component 21 to contact the edge of the circular glass workpiece fixed on the workbench 2 for grinding. At the same time, the motor 17 drives the gear 18 at its output end to rotate, and drives the gear 18 on the workbench 2 to rotate, so that the workbench 2 rotates, so as to fully process the edge of the glass workpiece, thereby achieving the purpose of trimming the glass.

The vacuum cleaner 22 is an existing mature technology, and the model and principle of the vacuum cleaner 22 are not described in detail here. The vacuum cleaner 22 does not belong to the main innovation direction of the present utility model, so the details of the vacuum cleaner 22 are not specifically displayed in the accompanying drawings.

[0046] The technical solution provided by this embodiment is: during the processing, by starting the vacuum cleaner 22, the negative pressure wind generated by it is collected through the dust hood and the pipeline, the dust generated by the trimming and floating in the protective shell 3 can be collected, thereby reducing the diffusion of dust and further ensuring the air quality of the working environment.
