[0018] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] The present invention provides the following embodiments to describe the present invention in detail:

[0020] Example

[0021] like Figure 1 As shown, a grinding device for automobile aluminum castings comprises a workbench 1 and a grinding bracket 2 arranged on the workbench 1, a guide rail 3 is arranged on the workbench 1, the guide rail 3 passes through the grinding bracket 2, a first linear cylinder 31 and a second linear cylinder 32 are symmetrically arranged on the guide rail 3, a buffer clamp 33 is arranged on the inner side wall of the first linear cylinder 31, and an ejector pin 34 is arranged on the inner side wall of the second linear cylinder 32, and a clamping area is formed between the buffer clamp 33 and the ejector pin 34;

[0022] Specifically, Figure 2 As shown, the buffer clamping member 33 includes a telescopic rod 331, a clamping cylinder 332 and a plurality of springs 333. The inner wall of the first linear cylinder 31 is fixed with the telescopic rod 331, the free end of the telescopic rod 331 is fixed with the clamping cylinder 332, and the plurality of springs 333 are evenly distributed around the telescopic rod 331, and one end of each spring is fixed to the inner wall of the first linear cylinder 31, and the other end of each spring is fixed to the outer wall of the clamping cylinder 332.

[0023] like Figure 1 and Figure 3 As shown, a cylinder 21 is provided on the grinding bracket 2, and a mounting frame 22 is fixed to the output end of the cylinder 21, and fixed plates 23 are fixed to both ends of the mounting frame 22. A motor 24 is provided on the outer side of one of the fixed plates 23, and a reciprocating screw 25 is fixed to the output shaft of the motor 24. The other end of the reciprocating screw 25 is rotatably connected to the inner wall of the other fixed plate 23, and the outer surface of the reciprocating screw 25 is threadedly connected to a symmetrical grinding movable table 26. Grinding wheels 27 are fixed to the inner walls of the two grinding movable tables 26, and a grinding area is formed between the two grinding wheels 27.

[0024] In order to prevent the grinding movable platform 26 from shifting, a slide bar is provided between the two fixed plates 23, and the slide bar is arranged parallel to the reciprocating screw 25. Through holes are provided on both grinding movable platforms 26, and the slide bar is arranged through the through holes.

[0025] In the above structure, the clamping area is larger than the grinding area. When the aluminum casting to be ground is located between the buffer clamp 33 and the ejector pin 34, the two grinding wheels 27 are in contact with the aluminum casting to be ground.

[0026] For ease of use, an observation window 28 is further provided on the polishing bracket 2 , the cylinder 21 is fixed on the observation window 28 , and the mounting frame 22 is located below the observation window 28 .

[0027] When in use, the automotive aluminum casting to be polished is placed in the clamping area, and the buffer clamp 33 and the ejector pin 34 are used to clamp the aluminum casting from both sides by controlling the expansion and contraction of the first linear cylinder 31 and the second linear cylinder 32. Since the buffer clamp 33 is provided with a spring 333, when the clamping claw cylinder 332 clamps the aluminum casting, the elastic effect of the spring 333 will buffer the clamping force, thereby preventing the aluminum casting from bending and deforming due to excessive clamping force. At the same time, by adjusting the expansion and contraction of the first linear cylinder 31 and the second linear cylinder 32, it can adapt to aluminum castings of different sizes, thereby improving the versatility of the device.

[0028] Next, the cylinder 21 is started to drive the mounting frame 22 and the two grinding wheels 27 fixed on the mounting frame 22 to approach the aluminum casting until the two grinding wheels 27 contact the aluminum casting. Then, the motor 24 is started, and the motor 24 drives the reciprocating screw 25 to rotate. Since the grinding movable platform 26 is threadedly connected to the reciprocating screw 25, the grinding movable platform 26 will reciprocate along the slide rod under the drive of the reciprocating screw 25, thereby driving the grinding wheels 27 to grind the aluminum casting. The situation during the grinding process can be observed through the observation window 28, which is convenient for the operator to adjust the grinding parameters or deal with abnormal situations in time.

[0029] In this way, not only the automotive aluminum castings are effectively polished, but also the bending and deformation of the aluminum castings during the polishing process are avoided by the design of the buffer clamp 33, thereby improving the quality and qualified rate of the products. At the same time, the device has a simple structure and is easy to operate, and is suitable for large-scale automotive aluminum casting production lines, thereby improving production efficiency.

[0030] In addition, the utility model can be further improved. For example, different grinding materials or particle sizes can be set on the grinding wheel 27 to adapt to aluminum castings with different surface roughness or hardness. At the same time, a sensor and a control system can be set on the grinding bracket 2 to monitor parameters such as temperature, pressure and speed during the grinding process in real time, and automatically adjust the grinding parameters according to these parameters to achieve a more accurate grinding effect. These improvements can further improve the performance and applicability of the device and meet a wider range of production needs.

[0031] Finally, it should be noted that the above are only preferred examples of the utility model and are not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
