Description

Technical Field

[0001] The utility model belongs to the technical field of glass processing equipment and relates to a spindle protective cover of a photovoltaic glass edge grinding machine. Background Art

[0002] When the edge grinding machine in the deep processing production line is working, the motor spindle is invaded by water vapor for a long time during use, which causes the emulsification and failure of the grease in the internal bearing of the spindle, causing the equipment to suddenly get stuck during use. Utility Model Content

[0003] The purpose of the utility model is to provide a spindle protective cover for a photovoltaic glass edge grinding machine in view of the above-mentioned problems existing in the prior art. The technical problem to be solved by the utility model is how to improve the reliability of the photovoltaic glass edge grinding machine.

[0004] The purpose of the utility model can be achieved through the following technical solutions: a spindle protective cover for a photovoltaic glass edge grinding machine, the photovoltaic glass edge grinding machine includes a casing, a spindle rotatably connected to the casing and a grinding wheel fixed on the spindle, characterized in that the spindle protective cover includes a cover body and an end plate, the cover body includes a bottom plate parallel to the end plate and an arc-shaped baffle located at the outer edge of the bottom plate, the arc-shaped baffle has a notch, the cover body is detachably connected to the casing, the end plate is detachably connected to the arc-shaped baffle, the grinding wheel is located between the end plate and the bottom plate, and the inner side surface of the end plate and the inner side surface of the bottom plate both have a plurality of guide ribs.

[0005] Furthermore, a coolant inlet hole is provided on the arc-shaped baffle at a position away from the notch.

[0006] In this scheme, the grinding wheel can be surrounded by a spindle protection cover, with only a portion of the grinding wheel exposed for contact with the grinding surface. Under the protective effect of the arc-shaped baffle plate, the slag and water vapor generated by grinding are guided to be discharged from the notch position. In addition, in order to prevent the accumulation of dirt and slag between the two end faces of the grinding wheel and the inner side surfaces of the end plate and the bottom plate, respectively, thereby preventing dirt and slag from accumulating between the two end faces of the grinding wheel and the inner side surfaces of the end plate and the bottom plate, thereby forming resistance to the rotation of the grinding wheel, guide ribs are respectively provided on the inner side surfaces of the end plate and the bottom plate. When water vapor and chips are affected by the rotation of the grinding wheel, the guide ribs can clean the two end faces of the grinding wheel to avoid the accumulation of slag and chips at this position. The inlet of the coolant is provided in the middle position of the arc-shaped baffle plate, that is, away from the notch. This can not only effectively utilize the coolant, but also optimize the effect of the guide ribs in cleaning the dirt. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0012] like Figure 1 , Figure 2 and Figure 3 As shown, the photovoltaic glass edge grinding machine includes a casing 1, a main shaft rotatably connected to the casing 1 and a grinding wheel 2 fixed on the main shaft, the main shaft protection cover includes a cover body 3 and an end plate 4, the cover body 3 includes a bottom plate 9 parallel to the end plate 4 and an arc-shaped baffle 5 located at the outer edge of the bottom plate 9, the arc-shaped baffle 5 has a notch 6, the cover body 3 is detachably connected to the casing 1, the end plate 4 is detachably connected to the arc-shaped baffle 5, the grinding wheel 2 is located between the end plate 4 and the bottom plate 9, the inner side surface of the end plate 4 and the inner side surface of the bottom plate 9 are provided with a plurality of guide ribs 7, and the position of the arc-shaped baffle 5 away from the notch 6 is provided with a coolant inlet 8; the rotation direction of the grinding wheel 2 is opposite to the inclination of the guide rib 7, so that the rotation of the grinding wheel 2 can drive the scale to flow in a direction away from the center of the grinding wheel under the action of the guide rib 7, and the scale tends to approach the inner wall surface of the arc-shaped baffle 5 and then be discharged from the notch.

[0013] In this solution, the grinding wheel 2 can be surrounded by a spindle protection cover, with only a portion of the grinding wheel 2 exposed for contact with the grinding surface. Under the protective effect of the arc-shaped baffle plate 5, the slag and water vapor generated by grinding are guided to be discharged from the position of the notch 6. In addition, in order to prevent the two end faces of the grinding wheel 2 from accumulating dirt and slag between the inner side surfaces of the end plate 4 and the inner side surfaces of the bottom plate 9, thereby forming resistance to the rotation of the grinding wheel 2, guide ribs 7 are respectively provided on the inner side surfaces of the end plate 4 and the inner side surfaces of the bottom plate 9. When water vapor and chips are affected by the rotation of the grinding wheel 2, the guide ribs 7 can clean the two end faces of the grinding wheel 2 to avoid the accumulation of slag and chips at this position. The inlet of the coolant is arranged in the middle position of the arc-shaped baffle plate 5, that is, away from the notch 6. This can not only effectively utilize the coolant, but also optimize the effect of the guide ribs 7 in cleaning the dirt.

[0014] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
