[0025] The inner side of one side of the support frame 8 is rotationally connected with a driving gear 801 and a driven gear 802 respectively, the driving gear 801 and the driven gear 802 are in meshing connection, the inner side of the other side of the support frame 8 is rotationally connected with an auxiliary A gear 803 and an auxiliary B gear 804 respectively, the auxiliary A gear 803 and the auxiliary B gear 804 are in meshing connection, the driving gear 801 and the auxiliary A gear 803 are integrally connected through the shaft rod penetrating at the shaft center thereof.

[0026] In the embodiment, as shown in Figure 1 and Figure 2 , one end of the bottom of the first moving base 3 penetrates through the first horizontal lead screw 2 and forms a screw transmission structure with the first horizontal lead screw 2; the first moving base 3 can realize accurate adjustment of a small position through the transmission structure of the first horizontal lead screw 2, which can ensure the accuracy of the polishing position and improve the processing quality.

[0027] In the embodiment, as shown in Figure 1 and Figure 2 , one end of the bottom of the second moving base 5 penetrates through the second horizontal lead screw 4 and forms a screw transmission structure with the second horizontal lead screw 4, and the first horizontal lead screw 2 and the second horizontal lead screw 4 are vertically distributed; through the cooperation of the first horizontal lead screw 2 and the second horizontal lead screw 4, the second moving base 5 can move in two axial directions, which greatly increases the flexibility of the workpiece in the polishing process, can adjust the position of the workpiece according to different polishing requirements, realizes multi-angle and multi-direction polishing operation, and at the same time, when the first moving base 3 and the second moving base 5 are driven by the first horizontal lead screw 2 and the second horizontal lead screw 4 respectively, the structure of the two auxiliary support sliding rods is additionally increased, which can effectively avoid the shaking and deviation of the two during movement, ensure smooth running on the predetermined track, and improve the precision and quality of the upper workpiece polishing.

[0028] In the embodiment, as shown in Figure 3As shown, the second mobile base 5 top is distributed with magnetic block 503 consistent with its specifications, and the clamping piece 502 adopts carbon fiber composite material, and the clamping piece 502 is connected through the reverse screw 501 to form relative motion, while the opposite side of the clamping piece 502, the surface of which is glued with rubber strips; although the magnetic attraction structure has a certain adsorption force on metal, it may loosen due to vibration, external impact and other factors during polishing.

Since the grinding wheel base 9 on which the polishing assembly is installed is integrally connected with the driven gear 802 and the auxiliary B gear 804, the grinding wheel base 9 can be flipped and rotated, so that the polishing assembly installed thereon can be easily adjusted in angle, and the polishing of metal panels at different angles can be realized. Whether it is a plane, a side or a curved surface, the appropriate polishing angle can be found, improving the flexibility and adaptability of polishing.

[0030] In this embodiment, as shown in Figure 1 and Figure 4As shown, the end points of the stand 6 are fixedly connected with the air spring hydraulic rods 10 corresponding to the two ends of the cylinder 7, and the bottom of the air spring hydraulic rod 10 is bolted with the top of the support frame 8; the driving of the cylinder 7 can realize the height adjustment of the grinding wheel base 9 to butt joint the workpiece below, and when the cylinder 7 is height-adjusted, the increase of the air spring hydraulic rod 10 can effectively inhibit the occurrence of the problem to ensure the smooth rising or falling of the grinding wheel base 9, which is crucial to ensure the polishing precision, and the air spring hydraulic rod 10 and the cylinder 7 jointly act, share the weight of the grinding wheel base 9 and the polishing assembly installed thereon, and various forces generated in the polishing process, to ensure the polishing precision.

[0032] The use method and advantages of the utility model are as follows:

[0033] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, first, the workpiece to be processed is placed on the surface of the second movable base 5. Because they are both metal materials, the magnetic block 503 on the surface of the second movable base 5 will have a certain adsorption force on the workpiece material, preliminarily fixing the position of the workpiece. At the same time, the power is started. First, the workpiece to be processed is placed on the surface of the second movable base 5. Because they are both metal materials, the reverse lead screw 501 rotates, causing the clamping members 502 at both ends to move relatively under the screw transmission structure, gradually approaching the workpiece, clamping and fixing the two ends of the workpiece, forming a double fixation mode of magnetic attraction and clamping, greatly improving the fixation stability of the workpiece. After the workpiece is fixed, the power output end of the air cylinder 7 pushes the support frame 8 to descend. During the descent of the support frame 8, the gas spring hydraulic rod 10 at both ends of the air cylinder 7 is stretched and unfolded accordingly, providing stability for the descent of the support frame 8. After adjusting to the appropriate working position, the operator adjusts the angle of the grinding wheel base 9 according to the needs of the process. In the initial position, the first grinding wheel 11 is located below the grinding wheel base 9 and above the workpiece. When a large area of the workpiece surface needs to be processed, after the power is started, the first horizontal lead screw 2 rotates, and the first movable base 3 slides on the surface of the operation table 1 in the X-axis direction through the screw transmission structure of the first horizontal lead screw 2. This allows the workpiece on the top to move below the first grinding wheel 11, thereby realizing the large-area rough grinding of the first grinding wheel 11 on the workpiece surface. At the same time, the second movable base 5 can also slide in the Y-axis direction on the first movable base 3 through the second horizontal lead screw 4, so that the first grinding wheel 11 is connected to the direction of another face domain of the workpiece. Again, through the transmission structure of the first horizontal lead screw 2, the position of the second movable base 5 is adjusted to realize the processing of different face domains. If the side face domain of the workpiece needs to be processed, first, adjust the first horizontal lead screw 2 and the second horizontal lead screw 4 to the appropriate position, and then drive the driving gear 801 to rotate through the power outside the support frame 8. The rotation of the driving gear 801 will cause the auxiliary A gear 803 connected coaxially to it to rotate synchronously, thereby causing the driven gear 802 and the auxiliary B gear 804 to rotate, and finally realizing the rotation of the grinding wheel base 9. After adjusting the second grinding wheel 12 to the appropriate position, the operation mode is consistent with the above operation mode. The position of the second movable base 5 is adjusted through the cooperative adjustment of the first horizontal lead screw 2 and the second horizontal lead screw 4 to realize the connection of the second grinding wheel 12 and the workpiece in the lateral direction. It should be noted that because the two ends of the workpiece are fixed by the clamping members 502, after the non-fixed end is processed, the power can be turned off, the workpiece can be taken out, and the space can be turned over or rotated to expose the unprocessed end for subsequent grinding processing.

The technical personnel in the industry should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only preferred examples of the present application and are not intended to limit the present application.
