Further, the lower squeeze cylinders comprise a set of fixed cylinders 6 corresponding to a set of breather pipes 4 far from the rotating sanding belt 20 and a set of height-adjustable adjusting cylinders 7 corresponding to a set of breather pipes 4 near the rotating sanding belt 20, and the height of the adjusting cylinders 7 is adjusted to change the fixed angle of the die casting 28. Because the height of the adjusting columns 7 is adjustable, when the top height of each adjusting column 7 is the same as that of each fixing column 6, the die casting 28 is in a horizontal fixed state, and the rotating abrasive belt 20 can perform plane grinding on the die casting 28; when the height of the top of each adjusting post 7 is lower or higher than that of each fixing post 6, the die cast 28 is in an inclined state, and the die cast 28 can be bevel-ground by rotating the abrasive belt 20. Compared with the prior art, when the die casting 28 is subjected to inclined surface grinding, the angle of the rotating abrasive belt 20 does not need to be adjusted and increased, and the die casting 28 can be fixed only by using a fixing mechanism, so that the operation is more convenient.

Through the design of the structure, when the die casting 28 is subjected to slope grinding, the adjusting screw 8 is enabled to move downwards by clockwise rotating the adjusting screw 8, the downward movement of the adjusting screw 8 drives the material receiving plate 9 to rotate downwards, the downward rotating material receiving plate 9 drives the two vertical rods 19 to slide downwards through the second horizontal column 16, and further drives the rotating shaft 22 and the cylinder 23 to move downwards vertically, and as the first horizontal column 15 and the second horizontal column 16 are both in sliding insertion connection with the strip hole 901, the heights of the cylinder 23 and the end of the die casting 28 to be ground are enabled to be the same, and further when the inclined die casting 28 is fixed, the end of the die casting 28 to be ground can still correspond to the position of the cylinder 23, so that the cylinder 23 can still be extruded when the die casting 28 is subjected to slope grinding, the rotating abrasive belt 20 in a grinding area is prevented from being bent, and the slope grinding quality of the die casting 28 is ensured.

When the rotating shaft 22 moves downwards, the two square blocks 24 are driven to move downwards synchronously, and at the moment, the two square blocks 24 respectively pull the corresponding extension springs 18 downwards, so that the elasticity of the extension springs 18 is increased, the elastic force of the extension springs 18 can enable the connecting parts to be stable and not prone to shaking, and the stability is improved.

The sliding arrangement of the square block 24 in the vertical direction is used for limiting the cylinder 23, so that the cylinder 23 can only move in the vertical direction, and further the cylinder 23 is always abutted against the rotary abrasive belt 20, so that the rotary abrasive belt 20 in the grinding area is kept in a vertical state when the die casting 28 is subjected to plane grinding and bevel grinding.

Furthermore, two ends of the rotating shaft 22 are fixedly provided with an arc-shaped fan 21, the two arc-shaped fans 21 are respectively located on the front side and the rear side of the rotating abrasive belt 20, when the die casting 28 is ground, a thrust force towards the rotating abrasive belt 20 is applied to the sliding frame 2, so that the die casting 28 extrudes the rotating abrasive belt 20, the rotating abrasive belt 20 extrudes the cylinder 23, the cylinder 23 rotates along with the rotation of the rotating abrasive belt 20 by utilizing a friction force between the rotating abrasive belt 20 and the outer surface of the cylinder 23, the rotation of the cylinder 23 drives the rotating shaft 22 to rotate, and then the two arc-shaped fans 21 are driven to rotate, the rotation of the two arc-shaped fans 21 generates an air flow to dissipate heat generated on the die casting 28 and the rotating abrasive belt 20 in the grinding process, and the heat dissipation efficiency of the die casting 28 and the rotating abrasive belt 20 is improved;

meanwhile, the free ends of the arc-shaped fan blades 21 extend to the position between the rotating abrasive belt 20 and the upper extrusion column 5, the two arc-shaped fan blades 21 also rotate downwards due to the fact that the rotating abrasive belt 20 in the grinding area rotates downwards, and the downward rotation of the arc-shaped fan blades 21 effectively prevents fine debris generated in the grinding process from splashing upwards and leftwards from the front side and the rear side of the rotating abrasive belt 20, so that the debris cannot splash onto an operator, the operation of the operator is safer, the debris cannot easily enter the operating sight line of the operator, and the operating sight line of the operator is clear;

moreover, the rotation direction of arc fan 21 is faced to the interior concave surface of arc fan 21 to make the air current that produces when arc fan 21 rotates flow downwards, the air current that flows downwards can drive the grinding in-process and produce the smoke and dust and flow downwards, and then can effectively prevent that the smoke and dust from blockking operator's sight, further improve the definition of operation sight.

While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that the described embodiments may be modified in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are illustrative in nature and should not be construed as limiting the scope of the invention.
