DETAILED DESCRIPTION

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] like Figures 1-2 As shown, a floating blade sharpener includes a frame 1. Connecting rods 9 are fixedly arranged on the frame 1 along the vertical direction. Preferably, there are four connecting rods 9 evenly distributed at the four corners of the frame 1. A bearing plate 2 is movably arranged on the connecting rods 9, so that the bearing plate 2 can slide on the four connecting rods 9. An elastic element 5 is also arranged between the frame 1 and the bearing plate 2. At the same time, a bearing 6 is arranged on the bearing plate 2. Specifically, the outer ring of the bearing 6 is fixedly arranged on the frame 1, and a base 7 is fixedly arranged on the inner ring of the bearing 6. A blade holder 8 is fixedly arranged on the base 7, and a blade 3 is arranged on the blade holder 8. A drive source 4 (pneumatic motor, etc.) is also arranged on the frame 1. The actuator of the drive source 4 is fixedly connected to the inner ring of the bearing 6. When the drive source 4 is working, its actuator can drive the inner ring of the bearing 6 to rotate, thereby realizing the rotation of the blade holder 8 and the blade 3.

[0033] When cleaning the shoulder a at the welding head is required, the robotic arm moves the welding head to the rotational working area of ​​the blade 3. Then, the drive source 4 is activated, allowing the blade 3 to rotate and grind the debris on the shoulder a. Since the debris on the shoulder a may be unevenly distributed and of different sizes, when the blade 3 rotates and comes into contact with debris of different sizes, the support plate 2 is movably mounted on the frame 1. When the blade 3 encounters larger and more adhesive debris, it can move vertically with the support plate 2, avoiding direct hard contact between the blade 3 and the debris, which could cause damage. At the same time, during this grinding process, the elastic element 5 acts on the support plate 2, ensuring that the blade 3 remains in contact with the shoulder a during vertical movement. This action achieves a floating effect for the blade 3, improving the grinding and cleaning effect on the shoulder a. It should be noted that the attached figure only shows a schematic diagram when the shoulder a is placed in the corresponding position of the blade 3, and does not show the robotic arm and other parts of the spindle.

[0034] In order to better perform the grinding treatment on the shaft shoulder a, the tool holder 8 is arranged in two groups, and the two groups of tool holder 8 are oppositely arranged, so that the two groups of blades 3 thereon form a grinding area for the shaft shoulder a to be inserted, when the mechanical arm drives the shaft shoulder a to move to the rotating working area of the blade 3, the shaft shoulder a is located in the grinding area, and in the subsequent work, the two groups of blades 3 can sequentially perform the grinding treatment on the same position of the shaft shoulder a, and the grinding effect is further improved.

[0035] For the arrangement of the elastic member 5, the elastic member 5 can be arranged as a conventional technical means in the prior art, and the elastic member 5 is preferably arranged as a return spring, and the return spring is sleeved on the connecting rod 9, and the two ends of the return spring are fixedly connected with the bearing plate 2 and the frame 1.

[0036] As shown in Figure 3 , in order to collect and temporarily store the waste generated in the grinding work, the grinder in the application further comprises a protective cover 10 arranged on the bearing plate 2 and used for covering the grinding area, and one side of the protective cover 10 is provided with a discharge gap. Figure 3 From the view, the discharge gap is arranged on the left side, and when the blade 3 rotates to grind the shaft shoulder a, the generated waste can be covered in the protective cover 10, and is discharged through the discharge gap, avoiding the waste scattered on the bearing plate 2. Further, in order to collect the waste discharged from the discharge gap, a group of waste boxes 11 can be arranged on the side of the frame 1. In order to better guide the waste through the discharge gap, a guide portion 12 extending from the discharge gap and located above the opening of the waste box 11 can be arranged.

[0037] As shown in Figure 4 , the grinder in the application further comprises a splash-proof cover 13 arranged on the top of the frame 1 and used for covering the bearing plate 2 and the protective cover 10, and the splash-proof cover 13 is provided with a through hole 15 on the top for the shaft shoulder a to pass through. At the same time, the grinder in the application further comprises a side cover 14 arranged on the side of the frame 1 and used for covering the connecting rod 9 and the elastic member 5.

[0038] The above describes one embodiment of the application in detail, but the content described is only a preferred embodiment of the application, and cannot be considered as limiting the scope of the application. Any equivalent changes and improvements made within the scope of the application should still belong to the patent coverage of the application.
