[0041] Working principle of the utility model: This embodiment is a grinding mechanism with three-axis movement and 360-degree position adjustment. The X-axis movement mechanism 7 can realize the position adjustment of the grinding component in the X-axis direction, and the Y-axis movement mechanism 8 can realize the position adjustment of the grinding component in the Y-axis direction, wherein the X-axis and the Y-axis directions are on the same horizontal plane and perpendicular to each other. Figure 1 It can be seen that in the four horizontal directions of the grinding assembly, the Z-axis direction is the vertical direction, which is perpendicular to the X-axis direction and the Y-axis direction. The Z-axis moving mechanism 9 can adjust the vertical height position of the grinding assembly.

[0042] The balancing frame 1 is a rectangular frame. The driving elements of the swing driving element 2, the grinding driving element 5, the X-axis driving element 74, the Y-axis driving element 83 and the Z-axis moving mechanism 9 can all be driven by motors. The swing driving element 2 is fixed in the middle of the balancing frame 1. The power output end of the swing driving element 2 is provided with a sprocket, and the flip shaft 3 is provided with a sprocket. The two are driven by a transmission chain 10. In this embodiment, the two flip shafts 3 are symmetrically arranged about the swing driving element 2. The two flip shafts 3 are respectively connected to the power output end of the swing driving element 2 through their own transmission chains 10, so that one swing driving element 2 drives the two flip shafts 3 to rotate, and there is no limit on the three flip shafts 3 connected through the transmission chain 10 to improve the grinding efficiency. Since the two flip shafts 3 correspond to two grinding components, one of the grinding wheels 4 can be a fine grinding wheel 4, and the other grinding wheel 4 is a rough grinding wheel 4. The fine grinding wheel 4 and the rough grinding wheel 4 swing at the same time, reducing other swinging devices, and can grind multiple surfaces at the same time. Each grinding wheel 4 corresponds to a grinding drive element 5, which is convenient for controlling the switch of the grinding wheel 4. The flip shaft 3 is hollow, and the lead of the grinding drive element 5 can pass through the bracket 12 and the flip shaft 3 and then be electrically connected to the electric slip ring 11. The electric slip ring 11 is used to provide control and power for the corresponding grinding drive element 5, and solve the problem of winding during the swinging process of the grinding component to avoid line entanglement or damage due to friction. The grinding wheel 4 is connected to the power output end of the grinding drive element 5 through the grinding transmission belt 6. It has a simple structure and is easy to repair and replace. The entire grinding component can be replaced through the bracket 12. Among them, the attached Figure 3 B1 and B2 are both lead positions of the grinding drive element 5 .

[0043] The distance between each flip axis 3 of the balancing frame 1 and the swing drive element 2 is the same, and the swing drive element 2 is located in the middle, so that it can work smoothly during the adjustment of the position and the grinding process, meet the stability requirements, and improve the quality of grinding. In this embodiment, the two grinding components are symmetrically arranged, and the movements are symmetrical during the swing process, and there will be no one-sided tilting. If multiple grinding components are set, multiple grinding components can be controlled to be distributed in a ring array with the swing drive element 2 as the center, or multiple grinding components can be symmetrically arranged with the vertical line of the swing drive element 2 as the center line. In addition, the X-axis moving mechanism 7, the Y-axis moving mechanism 8, and the Z-axis moving mechanism 9 can all select linear modules. In this embodiment, the installation direction of the flip axis 3 is perpendicular to the Z-axis moving mechanism 9, the balancing frame 1 and the Y-axis moving mechanism 8, the flip axis 3 is consistent with the power output end direction of the swing drive element 2, and the swing direction of the grinding component swings around the flip axis 3, that is, swings around the flip axis 3. Wherein the Z-axis moving mechanism 9 has a Z-axis slider (i.e., the moving end of the Z-axis moving mechanism 9), which is not marked in the accompanying drawings. The left and right directions at the left and right outer ends of the balance frame 1 refer to the directions in which the Y-axis slider of the Y-axis moving mechanism 8 moves, that is, the left and right sides of the front side of the balance frame 1. Figure 4As shown, two relatively arranged track swing components and two relatively arranged swing components can perform all-round grinding processing on the workpiece to be processed between the two track swing components, greatly improving the overall multi-faceted processing efficiency. Through the analysis of the structural characteristics of the product and in combination with this mechanism, the production efficiency can be greatly improved during the grinding or polishing process. At a relatively low cost, more grinding freedom and more flexible grinding parameter settings can be provided, which can be widely promoted and applied in actual automated production lines. The design of this application provides a contour-based trajectory idea when dealing with special-shaped or irregular workpieces to ensure the uniformity and equivalence of grinding.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
