[0016] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with the drawings and specific embodiments.

[0017] As Figures 1 to 2 shown, a polishing head structure in a belt polishing equipment proposed by the present invention includes a connecting body 1 connected to the main body of the belt polishing equipment. The connecting body 1 is made of metal. The lower end of the connecting body 1 is detachably connected with a polishing head body 2 for winding the sand belt and for pressing the sand belt against the workpiece. The polishing head body 2 is elastically arranged, and the specific material can be rubber. The shape of the polishing head body 2 can be adjusted according to actual use requirements. In this embodiment, the cross-section of the polishing head body 2 is preferably arranged in an isosceles triangle shape, and chamfers are provided at the corners.

[0018] The detachable connection structure between the connecting body 1 and the polishing head body 2 is specifically as follows: A connecting piece 3 is fixedly connected to the polishing head body 2. The connecting piece 3 is made of metal. Part of the connecting piece 3 is embedded inside the polishing head body 2. The connecting piece 3 is located at the center of the polishing head body 2. Two mounting holes 4 for connection are provided on the connecting piece 3. An installation notch 6 is provided on one side wall of the connecting body 1. The connecting piece 3 can be attached to the side wall of the installation notch 6. Two threaded holes 5 that cooperate with the mounting holes 4 are provided on the side wall of the installation notch 6. A bolt is passed through between the mounting hole 4 and the threaded hole 5. The detachable connection between the connecting body 1 and the polishing head body 2 can be realized through the bolt, which is convenient for the disassembly and replacement of the polishing head body 2. At the same time, the above structure is simple and has high connection strength. In addition, it can effectively reduce the replacement amount and lower the cost.

[0019] The connecting body 1 is provided with a positioning hole 7 and an adjustment hole 8 for connecting with the main body of the belt polishing equipment. The positioning hole 7 and the adjustment hole 8 are also connected to the main body of the belt polishing equipment through bolts. The arrangement direction of the positioning hole 7 and the adjustment hole 8 is set along the length direction of the connecting body 1. In this embodiment, the adjustment hole 8 is arc-shaped, and the center of the arc of the adjustment hole 8 is consistent with the center of the positioning hole 7. By setting the adjustment hole 8 to be arc-shaped, it is possible to deflect the angles of the connecting body 1 and the polishing head body 2 relative to the belt polishing equipment without disassembling the connecting body 1, so that the abrasive belt at different positions of the polishing head body 2 can contact the workpiece, that is, it can realize surface contact with the workpiece and also realize line contact with the workpiece, and can be used under different working conditions, improving the applicable range.
