[0003] At present, in the process of beveling the rearview mirror glass of automobiles, bearing edge grinding machines are generally used as the main machine. In the process of beveling the glass of the bearing edge grinding machine, due to the different gaps between the bearings, the glass advance direction is uneven and distorted. Therefore, there are two existing solutions. One is to add a piece of glass behind the raw material to enhance the hardness. However, this method is not convenient when loading and unloading with a robot, which is not conducive to the realization of factory automation; the other is to use the chain row structure disclosed in the announcement number CN222002912U to avoid this problem. However, after the chain is installed, it is difficult to achieve the required accuracy of the parallelism between the chain plate surface and the axis between the chain links when it is subjected to force. In addition, in the assembly of the chain structure, the chain plate width and the chain pitch need to be matched accordingly.

[0025] By adopting the cooperative setting of the transmission component and the keyway 1 to replace the traditional chain structure, there is no need to match the width of the chain plate and the pitch of the chain during installation. At the same time, it also ensures that the rear chain plate 2 on the working surface side of the rear beam 100 can slide smoothly on the keyway 1, avoiding the situation of distortion caused by uneven glass advancing direction due to bearing clearance problems, ensuring the accuracy of the flatness of the rear chain plate, which is practical and convenient; and through the contact transmission connection setting of the transmission component and the non-working surface side of the rear beam 100, it can also reduce the resistance during the transmission process, which is practical and convenient.

[0026] Specifically, the transmission working principle of this embodiment is as follows: The motor outputs power, which is transmitted to the sprocket at the output end through the turbine box and the universal drive shaft. The sprocket contacts the transmission bearing group 4 to drive the rear chain plate 2 to rotate. The semi-circular head at the input end also contacts the transmission bearing group 4, and the semi-circular head can adjust the tightness of the rear chain plate. During grinding, the transmission bearing group 4 at the working surface does not contact the rear beam 1, which is the key design of this application; it is also the basis for distinguishing traditional bearing machines! The working surface is the benchmark of the whole machine and the key of the key; at this time, the rear chain plate 2 and the keyway 1 are in sliding contact work, avoiding the gaps that may occur in bearing contact, and effectively ensuring the accuracy in product processing.

[0027] In this embodiment, for the edging machine adopting the transmission structure for grinding large bevels of glass of the present application, it has less distortion of the rearview mirror, good diagonal of the bevel, better effect than the original traditional bearing machine, long service life, and reduces the frequency of replacing the chain plate bearings.

[0028] In this embodiment, for the bearing edging machine adopting the transmission structure for grinding large bevels of glass of the present application, the transmission structure between the front chain plate and the front beam can keep the original structure unchanged, or the transmission structure for grinding large bevels of glass of the present application can be adopted to replace the original structure, making the processed product have a better effect.

[0029] In this embodiment, the rear chain plate 2 surrounds the rear beam 100 and is arranged in a runway shape, and the rear beam 100 is placed inside the rear chain plate 2. Figures 2 - 4 Among them, the rear chain plate 2 and the transmission component on the non-working surface side of the rear beam 100 are omitted and not shown.

[0030] In this embodiment, the working surface of the rear beam 100 is also the side of the processing station for grinding the glass, and the non-processing surface is the other side of the rear beam 100 opposite to the processing station.

[0031] In this embodiment, the transmission structure for grinding the large bevel edge of the glass can also be used for the large bevel edge grinding processing of crystals, rock slabs, stones, etc.

[0032] Further, the transmission assembly includes a plurality of support bearing groups 3 and transmission bearing groups 4 arranged on the rear chain plate 2, and a chute 5 opened on the rear beam 100. The support bearing groups 3 extend into the chute 5 and are in transmission connection with the upper and lower side walls of the chute 5. Among them, the transmission bearing group 4 on the side of the working surface of the rear beam 100 is arranged in non-contact with the rear beam 100, and the transmission bearing group 4 on the side of the non-working surface of the rear beam 100 is arranged in contact transmission with the rear beam 100.

[0033] Specifically, the transmission bearing group 4 includes a connecting seat structure 41 arranged on the rear chain plate 2 and horizontal transmission bearings 42 rotatably arranged at the upper and lower ends of the connecting seat structure 41. Among them, the horizontal transmission bearings 42 on the side of the working surface of the rear beam 100 are arranged in non-contact with the rear beam 100, and the horizontal transmission bearings 42 on the side of the non-working surface of the rear beam 100 are arranged in contact transmission with the rear beam 100.

[0034] The connecting seat structure 41 includes support seats 411 symmetrically arranged at the upper and lower ends of the rear chain plate 2 facing the rear beam 100, and a connecting rod 412 connected between the two support seats 411. The two horizontal transmission bearings 42 are respectively rotatably connected to the upper and lower ends of the connecting rod 412.

[0035] By symmetrically arranging the horizontal transmission bearings 42 up and down, the transmission force of the transmission bearing group 4 is evenly distributed during the transmission process, ensuring the smoothness of the transmission process.

[0036] Specifically, the support bearing group 3 includes a support rod 31 arranged on the rear chain plate 2 between the two splines 1, and a support bearing 32 rotatably arranged at the outer end of the support rod 31 and extending into the chute 5. The upper and lower ends of the support bearing 32 are respectively in close contact with the two side walls of the chute 5.

[0037] By restricting the up and down movement of the support bearing 32 through the chute 5, the relative position relationship between the support bearing 32 and the rear beam 100 is maintained, thereby maintaining the vertical position relationship between the rear chain plate 2 and the rear beam 100, ensuring the stability and smoothness of the transmission process. Thus, the stability of the chain plate advancement is ensured.

[0038] Further, the plurality of support bearing groups 3 and the plurality of transmission bearing groups 4 are respectively arranged at staggered intervals along the length direction of the rear chain plate 2.

[0041] Through the cooperation of the horizontally arranged limiting bearing 62 and the limiting plate 64, during the grinding process, the limiting plate 64 contacts the limiting bearing 62 and applies a lateral force to the limiting bearing 62 to offset the force of the glass pressing on the lower end of the rear link plate 2 during transmission, keeping the rear link plate 2 always maintained in the corresponding vertical position, preventing the rear link plate 2 from tilting due to uneven force during the grinding process, and ensuring the stability during the transmission process. And this structure is directly installed on the rear link plate, with direct force application, more reliable and labor-saving.

[0042] In this embodiment, through the detachable setting of the adjusting rod 63, the adjusting rod 63 can be detached, and then according to the specific position of the rear link plate 2, the installation position of the adjusting rod 63 can be selected, so as to adjust the tilting distance of the limiting bearing 62, ensure that the tilting angle of the rear link plate 2 is not too large, which is practical and convenient.

[0043] Furthermore, a waterproof structure 7 is provided at the lower end of the rear link plate 2 to shield the insert strip 1.

[0044] Specifically, the waterproof structure 7 includes a clamping protrusion 71 provided at the lower end of the rear link plate 2, and a water baffle 72 that can be inserted into the clamping protrusion 71.

[0045] Through the setting of the water baffle 7, it is possible to prevent water splashes during the grinding process, so as not to cause adverse effects on the insert strip 1 and the transmission bearing group 4, ensure the smooth progress of the transmission process, and can extend the service life of the equipment, which is practical and convenient.

[0046] In summary, in the embodiment of the present application, by adopting the cooperative setting of the transmission component and the insert strip 1 to replace the traditional chain structure, the cost is low, there is no need to match the width of the link plate and the pitch of the chain during installation, the installation steps are simple and efficient, and at the same time, it is ensured that the rear link plate 2 on one side of the working surface of the rear beam 100 can slide smoothly on the insert strip 1, avoiding the situation of distortion caused by the uneven forward direction of the glass due to bearing clearance problems, ensuring the accuracy of the flatness of the rear link plate, which is practical and convenient; and by setting the transmission component to be in contact and transmission connection with the non-working surface side of the rear beam 100, the resistance during the transmission process can also be reduced, which is practical and convenient;

[0047] Also, through the cooperation of the horizontally arranged limit bearing 62 and the limit plate 64, during the grinding process, the limit plate 64 contacts the limit bearing 62 and applies a lateral force to the limit bearing 62 to counteract the force exerted by the glass on the lower end of the rear chain plate 2 during transmission, keeping the rear chain plate 2 in the corresponding vertical position all the time, preventing the rear chain plate 2 from tilting due to uneven force during the grinding process, and ensuring the stability during the transmission process;

[0048] And through the setting of the water baffle 7, it prevents the water splashing randomly during the grinding process, so as not to cause adverse effects on the insert strip 1 and the transmission bearing group 4, ensures the smooth progress of the transmission process, and can extend the service life of the equipment, which is practical and convenient.
