[0027] With reference to Figures 1-3 The utility model provides an embodiment: a section bar chamfering machine, including operation platform 1, operation platform 1 top middle end is provided with board 22, operation platform 1 top left -hand post fixedly connected with support seat 2, support seat 2 front side bottom rotatable connection has movable arm 3, movable arm 3 is connected with fixed plate 11 through lifting assembly 10, fixed plate 11 top side middle end rotatable connection has mounting seat 12, mounting seat 12 top fixedly connected with motor 13, mounting seat 12 bottom side is connected with grinding head 15 through installation component 14, support seat 2 top fixedly connected with arc support 4, arc support 4 is connected with movable arm 3 through sliding assembly 5, movable arm 3 top rotatable connection has positioning rod 8, the nut 9 of screw thread connection has in the positioning rod 8 outer wall rear end, arc support 4 outer wall top side fixedly connected with a plurality of clamping seat 6, a plurality of clamping seat 6 is connected with positioning rod 8 through positioning groove 7.

[0028] Specifically, movable arm 3 can rotate around support seat 2, and the angle of movable arm 3 can be conveniently adjusted by the sliding of sliding rod 502 in arc-shaped groove 501 in sliding assembly 5, so that the chamfering angle of grinding head 15 to board 22 can be conveniently adjusted, and different chamfering requirements can be met. The design of flexible angle adjustment greatly improves the processing adaptability of the section bar chamfering machine. In actual production, different sections may need different chamfering angles, and traditional chamfering machines can only perform single-angle chamfering processing. However, the section bar chamfering machine can quickly and accurately adjust grinding head 15 to the required chamfering angle by rotating movable arm 3 and sliding sliding rod 502 in arc-shaped groove 501, without the need to replace complex molds or perform tedious debugging, greatly saving processing time and improving production efficiency. Moreover, accurate angle adjustment can also ensure the accuracy of chamfering, so that the quality of processed section chamfering is higher, meeting various high-precision production requirements, reducing the rate of defective products, and reducing production costs.

[0029] By rotating the extension rod 17 to drive the gear 16 to rotate, the gear 16 is engaged with the toothed plate 1002, so as to realize the movement of the fixed plate 11 along the sliding groove two 1001 to drive the grinding head 15 to move up and down, which can easily adapt to the chamfering work of different thicknesses of the plate 22, and improve the versatility of the equipment. When facing different thicknesses of the plate 22, the traditional chamfering machine may need to replace different specifications of equipment or make complex height adjustment, which is difficult to operate and low in efficiency. The profile chamfering machine utilizes the engagement transmission of the gear 16 and the toothed plate 1002, so that the height adjustment of the grinding head 15 becomes simple and efficient. The operator only needs to rotate the extension rod 17 to accurately control the up and down movement of the grinding head 15, so as to quickly adapt to the chamfering needs of different thicknesses of the plate 22. This not only improves the use range of the equipment, so that one equipment can process many different specifications of the profile, but also reduces the cost investment of enterprises in equipment procurement.

The use of the tension spring 21 makes the positioning process more automated, and the operator can complete the positioning without additional tools or complex operations, reduces the influence of human factors on the positioning accuracy, and improves the positioning accuracy and stability. After the angle of the movable arm 3 is adjusted, the positioning rod 8 is clamped into the positioning slot 7 of the different clamping seat 6 and the nut 9 is tightened, so as to fix the angle of the movable arm 3. This multi-angle positioning method can firmly fix the movable arm 3 at the required angle position, avoid the shaking or displacement of the movable arm 3 during chamfering, so as to ensure the accuracy and quality of chamfering. At the same time, the design of multiple clamping seats 6 provides more angle selection, further enhances the flexibility and adaptability of the equipment, and meets the needs of different users in different processing scenes.
