Description

Technical Field

[0001] The invention relates to the technical field of grinding equipment, and in particular to a grinding equipment for surface treatment in the production of metal cabinet panels. Background Art

[0002] Grinding of metal cabinet panels is a key processing technology used to improve panel quality. Its main purpose is to improve flatness, eliminate bumps and deformations caused by stamping and welding in manufacturing, provide a good foundation for subsequent assembly, improve surface roughness, remove micro-roughness, make the panel smoother, reduce dirt adhesion and facilitate cleaning, ensure dimensional accuracy, and accurately control panel thickness, edge size, etc. to meet tolerance requirements. This process includes rough grinding and fine grinding. Rough grinding uses large-grained grinding wheels or abrasives to quickly remove most of the excess, improve flatness and initially reduce roughness. Commonly used equipment includes surface grinders, which drive the workpiece to reciprocate and grind with a grinding wheel through a workbench. It is suitable for large-area planes. There are horizontal axis rectangular tables, vertical axis rectangular tables, etc. There are also belt grinders, which use annular belts for high-speed grinding, with high efficiency, good surface quality, and strong adaptability. The existing grinding equipment is usually difficult to control the amount of abrasive during grinding, and the abrasive is difficult to add automatically, so we proposed a grinding equipment for surface treatment of metal cabinet panel production. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a grinding device for surface treatment of metal cabinet panels, comprising: A bottom plate, the top of which is fixedly connected with a column, four of which are arranged at the four corners of the bottom plate; A grinding mechanism, wherein the grinding mechanism is fixedly connected to the top of the bottom plate, and the column passes through the grinding mechanism, and the surface of the column is slidably connected to the inner side of the grinding mechanism; A fixing mechanism, the fixing mechanism is arranged directly below the grinding mechanism and the fixing mechanism is fixedly connected to the top of the bottom plate; Wherein, the grinding mechanism comprises: A connecting plate, wherein a driving assembly is fixedly connected to a side of the connecting plate away from the bottom plate, and the driving assembly is fixedly connected to the top of the bottom plate; A grinding cylinder, the outer side of which is fixedly connected to the inner side of the connecting plate, and a grinding block is fixedly connected to one side of the grinding cylinder close to the bottom plate; The side of the grinding block away from the grinding cylinder is inwardly concave, the inner side of the grinding cylinder is slidably connected with a polishing rod, and the polishing rod is made of solid polishing agent, the polishing rod extends into the inside of the grinding block, and the polishing rod is slidably connected to the inner side of the grinding block; A bar assembly, wherein the bar assembly is arranged on a side of the grinding cylinder away from the bottom plate, and a surface of the bar assembly is slidably connected to an inner side surface of the grinding cylinder; A cooling component, wherein the cooling component is fixedly connected to the surface of the driving component; The cabinet panel is fixed by a fixing mechanism, and then the polishing rod is inserted from the grinding block, the polishing rod enters the inside of the grinding cylinder, and the driving assembly is started. The driving assembly drives the connecting plate to move, drives the grinding cylinder to move, and drives the grinding block to move, so as to realize the grinding of the entire cabinet panel. During grinding, the polishing rod first contacts the cabinet panel, and the polishing rod moves with the grinding block under the action of friction. The friction generates heat, causing the polishing rod to melt, and the polishing agent melts into the surface of the cabinet panel to provide abrasive for grinding. The abrasive accumulates in the depression of the grinding block, and the cabinet panel is polished as the grinding block moves. The grinding of the grinding cylinder generates heat, which can further melt the polishing rod. The polishing rod loses the support provided by the cabinet panel, and slides out of the grinding block under the pressure of the rod assembly, so that the polishing rod continues to contact the cabinet panel, thereby realizing automatic addition of abrasive.

The loading spring is in a stretched state to continuously provide pressure for the polishing rod. When the other end of the polishing rod melts, the loading spring drives the rod barrel to squeeze the polishing rod, and the rod barrel slides inside the annular groove, and the polishing rod slides out of the grinding block, thereby realizing automatic addition of abrasive.

[0005] Furthermore, the driving assembly includes a first slide rail, a side of the first slide rail close to the base plate is fixedly connected to a side of the connecting plate away from the base plate, and the connecting plate is fixedly connected to an output end of the first slide rail, second slide rails are provided at both ends of the first slide rail, and the sides of the two second slide rails close to each other are respectively fixedly connected to the two ends of the first slide rail, and the output ends of the first slide rail and the second slide rail are fixedly connected, when the first slide rail is started, the first slide rail drives the connecting plate to move horizontally, and when the second slide rail is started, the second slide rail drives the first slide rail to move longitudinally, and drives the connecting plate to move longitudinally, thereby finally realizing the grinding of the entire cabinet panel by the grinding block.

[0008] Furthermore, the air inlet pipe is located on a side of the first slide rail away from the bottom plate, and a filter is fixedly connected to one end of the air inlet pipe away from the pump body. The filter is arranged directly above the first slide rail. The filter is arranged to filter the air entering the air inlet pipe to remove impurities and excess moisture, thereby preventing impurities and moisture from adhering to the surface of the cabinet panel, thereby preventing the abrasive particle size from increasing and affecting the grinding accuracy. Removing moisture can avoid affecting the abrasive consistency and ensure the grinding effect.

[0009] Furthermore, a fixing plate is fixedly connected to the outer side surface of the bent pipe, and the side of the fixing plate away from the bent pipe is fixedly connected to the side surface of the first slide rail. A protective cover is fixedly connected to the end of the bent pipe close to the bottom plate. The setting of the protective cover can increase the air outlet area and obtain a cooling effect over a larger range.

[0013] The present invention has the beneficial effects: The present invention provides a grinding mechanism. The polishing rod moves with the grinding block under the action of friction. The friction generates heat to cause the polishing rod to melt. The polishing agent melts to the surface of the cabinet panel to provide abrasive for grinding. The abrasive accumulates in the depression of the grinding block. As the grinding block moves, the cabinet panel is ground. The grinding of the grinding cylinder generates heat, which can further melt the polishing rod. The polishing rod loses the supporting force provided by the cabinet panel and slides out of the grinding block under the pressure of the rod assembly, so that the polishing rod continues to contact the cabinet panel, thereby realizing automatic addition of abrasive.

[0014] The present invention arranges a rod assembly, and the feeding spring is in a stretched state to continuously provide pressure for the polishing rod. When the other end of the polishing rod melts, the feeding spring drives the rod barrel to squeeze the polishing rod, the rod barrel slides inside the annular groove, and the polishing rod slides out of the polishing block, thereby realizing automatic addition of abrasive.
