DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0024] Example 1

[0025] like Figure 1-3 As shown, an automatic angle grinder includes two parallel and spaced guide rails 1, with a reciprocating V-shaped bracket 2 disposed between the two guide rails 1. The sidewalls of the V-shaped bracket 2 slide along the guide rails 1. The V-shaped bracket 2 has an upward opening and a downward tip, with an angle grinding hole 3 defined at the tip. The angle grinding hole 3 is elongated and arranged along the direction of movement of the V-shaped bracket 2.

[0026] A grinding wheel 4 for grinding angles is provided below the angle grinding hole 3. The grinding wheel 4 is placed horizontally below the angle grinding hole, and the upper end surface of the grinding wheel 4 is located near the edge and corresponds to the angle grinding hole 3. The grinding wheel 4 uses a flat surface to grind the angles. The grinding wheel 4 is driven to rotate by a motor, and the workpiece 12 is ground by the rotating grinding wheel 4. Push holes 5 are provided on the V-shaped brackets 2 on both sides of the angle grinding hole 3. A telescopic push plate 6 is provided at the push hole 5. The distance between the telescopic push plate 6 and the angle grinding hole 3 is less than the height of the workpiece 12, but greater than half the height of the workpiece 12. For example, if the distance between the telescopic push plate 6 and the angle grinding hole 3 is less than the height of the workpiece 12, but greater than half the height of the workpiece 12, such as being located at 2 / 3 of the height of the workpiece 12, that is, the telescopic push plate 6 pushes the workpiece 12 near the upper end, so that the workpiece 12 can be turned over smoothly.

[0027] One end of the telescopic push plate 6 is a free end and is placed in the pushing hole 5. The other end of the telescopic push plate 6 is connected to the first telescopic cylinder 7. The first telescopic cylinder 7 is fixed to the outer wall of the V-shaped bracket 2. The first telescopic cylinder 7 contracts, driving the telescopic push plate 6 to pass through the pushing hole 5 and push the workpiece 12 to flip, so that the edge to be ground of the workpiece 12 is placed in the grinding hole 3. The first telescopic cylinder 7 extends, driving the telescopic push plate 6 to reset.

[0028] The V-shaped bracket 2 also houses a positioning mechanism for clamping and securing the workpiece 12. This mechanism comprises a fixed end plate 8, a movable end plate 9, and a side top plate 10. The fixed end plate 8 is secured to one end of the angle-grinding hole 3, while the movable end plate 9 slides over the other end. The end of the movable end plate 9, facing away from the hole 3, is connected to a third telescopic cylinder, which is secured to the V-shaped bracket 2. The movable end plate 9 and the fixed end plate 8 work together to clamp and secure both ends of the workpiece 12.

[0029] Two side top plates 10 are provided, one on each side of the grinding hole 3, and slide along the inner side of the V-shaped bracket 2. The side top plates 10 are located above the push hole 5. The lower end of the side top plates 10 is free, and the upper end is fixed with a second telescopic cylinder 11, which is fixed to the inner side wall of the V-shaped bracket 2. The side top plates 10 cooperate to clamp the workpiece 12 to the bottom side wall of the V-shaped bracket 2.

[0030] Example 2

[0031] like Figure 2 and 3 As shown, a method for using an automatic angle grinder includes the following steps:

[0032] (1) Place the workpiece 12 in the V-shaped bracket 2, and place an edge of the workpiece 12 to be ground in the grinding hole 3. The bottom surface 13 and the lower side surface 14 adjacent to the edge to be ground are respectively against the two side walls of the V-shaped bracket 2; the positioning mechanism clamps and fixes the workpiece 12, and the V-shaped bracket 2 drives the workpiece 12 to pass through the grinding wheel 4, and the grinding wheel 4 grinds the edge to be ground;

[0033] (2) Then, the telescopic push plate 6 adjacent to the lower side 14 extends out of the push hole 5, pushing the workpiece 12 to flip over, so that the other edge of the workpiece 12 to be ground is placed at the grinding position. At this time, the bottom surface 13 and the upper side surface 15 of the workpiece 12 respectively abut against the two side walls of the V-shaped bracket 2. The positioning mechanism clamps and fixes the workpiece 12. The V-shaped bracket 2 drives the workpiece 12 to pass through the grinding wheel 4, and the grinding wheel 4 grinds the edge to be ground;

[0034] (3) Finally, the telescopic push plate 6 adjacent to the upper side surface 15 extends out of the push hole 5, so that the upper end of the workpiece 12 is away from the side wall of the V-shaped bracket 2, and the worker takes out the processed workpiece 12.

[0035] In steps (1) and (2), the specific method for the positioning mechanism to clamp and fix the workpiece 12 is as follows: first, the movable end plate 9 slides to push the workpiece 12, so that the other end of the workpiece 12 abuts against the fixed end plate 8, and then resets; then the two side top plates 10 move down to push the workpiece 12 and reset, so that the bottom surface and the lower side surface (or upper side surface) of the workpiece 12 abut against the side wall of the V-shaped bracket; finally, the movable end plate 9 and the two side top plates 10 press the workpiece 12 in turn, and the order of the two side top plates 10 is not limited. By the above method, the position of the workpiece can be located first, and then clamped and fixed, to avoid inaccurate positioning of the workpiece and affecting the processing quality.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
