Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Specific implementation examples are given below.

[0020] Please see Figures 1-6 This utility model provides an aluminum alloy workpiece polishing device, including a machine tool 1. A fixed plate 2 is fixedly connected to one end of the top of the machine tool 1. A first motor 21 is fixedly connected to the fixed plate 2. The output shaft of the first motor 21 is rotatably connected to the fixed plate 2 via a bearing. A bidirectional lead screw 23 is fixedly connected to the output shaft of the first motor 21. Two moving plates 22 are threadedly connected to the bidirectional lead screw 23. A fixed seat 221 is rotatably connected to each moving plate 22 via a rotating rod. An adjusting plate 222 is slidably connected to each fixed seat 221. An adjusting bolt 223 is rotatably connected to each fixed seat 221 via a bearing. The adjusting plate 222 is threadedly connected to the adjusting bolt 223. A side plate 226 is fixedly connected to the side wall of each fixed seat 221. A triangular block 225 is rotatably connected to each side plate 226 via a rotating shaft. A cross locating pin 227 is inserted into the top of each rotating shaft.

[0021] During operation, to address the inconvenience of clamping and polishing round workpieces, the first motor 21 is activated. The output shaft of the first motor 21 drives the bidirectional lead screw 23 to rotate, which in turn moves two moving plates 22. These moving plates 22 then move the fixed base 221 and the adjusting plate 222 to the appropriate positions. The workpiece to be polished is then placed on the fixed base 221. If the workpiece is rectangular, the triangular block 225 rotates away from the adjusting plate 222. The rotating shaft is then fixed by the cross locating pin 227, facilitating workpiece placement. Finally, the adjusting bolt 223 is rotated, causing the workpiece to... The adjusting plate 222 moves downward until the workpiece is clamped and fixed. If the workpiece is round, the triangular block 225 rotates towards the adjusting plate 222, and then the rotating shaft is fixed by the cross positioning pin 227. The round workpiece is clamped on the fixed seat 221 by the triangular block 225. Then, by rotating the adjusting bolt 223, the adjusting plate 222 moves downward until the workpiece is clamped and fixed, thus realizing the function of clamping workpieces of different shapes. Rubber pads are attached to the surfaces of the fixed seat 221, adjusting plate 222 and triangular block 225 that are in contact with the workpiece to be polished to prevent scratches on the workpiece.

[0022] Furthermore, such as Figure 3 As shown, a second motor 224 is fixedly connected to the side wall of one of the movable plates 22, and the output shaft of the second motor 224 is fixedly connected to one end of the rotating rod.

[0023] During operation, in order to polish different surfaces of the workpiece, the second motor 224 needs to be turned on. The output shaft of the second motor 224 drives the fixed seat 221 to rotate, and the fixed seat 221 drives the workpiece to rotate, thereby achieving full polishing of the workpiece.

[0024] Furthermore, such as Figure 2 As shown, a fixed frame 4 is fixedly connected to one end of the machine tool 1 away from the fixed plate 2. One end of the bidirectional lead screw 23 is rotatably connected to the fixed frame 4 through a bearing. Two guide rods 24 are fixedly connected between the fixed frame 4 and the fixed plate 2. The moving plate 22 is slidably connected on the guide rods 24.

[0025] During operation, the movable plate 22 slides on the guide rod 24, which limits the movement of the movable plate 22 in the horizontal direction.

[0026] Furthermore, such as Figure 1 and Figure 4As shown, a third motor 41 is fixedly connected to the top of the fixed frame 4. The output shaft of the third motor 41 is rotatably connected to the fixed frame 4 via a bearing, and a rotating frame 42 is fixedly connected through the fixed frame 4. A fourth motor 421 is fixedly connected to the side wall of the rotating frame 42. The output shaft of the fourth motor 421 is rotatably connected to a reciprocating lead screw 422 via a bearing. A moving block 424 is threadedly connected to the reciprocating lead screw 422. Two limiting rods 423 are fixedly connected to the rotating frame 42, and the moving block 424 is slidably connected to the two limiting rods 423.

[0027] During operation, to expand the polishing area, for rectangular workpieces, the fourth motor 421 is activated, and its output shaft drives the reciprocating screw 422 to rotate. The reciprocating screw 422 then moves the moving block 424, thus polishing the horizontal surface of the workpiece. When polishing the width of the workpiece is required, the third motor 41 is activated, and the angle of the rotating frame 42 is adjusted to achieve full polishing of the workpiece. For circular workpieces, the position of the moving block 424 can be adjusted using the fourth motor 421 to determine the polishing radius. Then, the third motor 41 is activated, driving the rotating frame 42 and the moving block 424 to rotate, thus achieving full polishing of the workpiece.

[0028] Furthermore, as shown in the figure and Figure 5 As shown, a first electric push rod 43 is fixedly connected to the bottom of the moving block 424, and a mounting base 431 is fixedly connected to the output end of the first electric push rod 43. The main body 432 of the polishing equipment is mounted on the mounting base 431. A rectangular plate 433 is fixedly connected to the two side walls of the first electric push rod 43. Two sliding rods 434 are fixedly connected to the top of the mounting base 431, and the sliding rods 434 are slidably connected to the rectangular plate 433.

[0029] When polishing workpieces of different thicknesses during operation, the first electric actuator 43 is activated. The output end of the first electric actuator 43 drives the mounting base 431 to move, which in turn drives the polishing equipment body 432 to move. The polishing equipment body 432 then grinds and polishes the workpiece. During the movement of the mounting base 431, it drives the sliding rod 434 to move. When the sliding rod 434 slides on the side plate 226, it limits the movement of the mounting base 431 and the polishing equipment body 432 in the vertical direction.

[0030] Furthermore, such as Figure 5As shown, a dust collection box 443 is fixedly connected to the top of the rotating frame 42, and a suction pipe 441 is connected and fixedly connected to the dust collection box 443. A connecting frame 44 is fixedly connected to the side wall of the mounting base 431. A suction hood 442 is connected and fixedly connected to one end of the suction pipe 441. The top end of the suction hood 442 is installed through the mounting base 431. A fan 444 is provided on one side of the dust collection box 443.

[0031] During operation, debris and impurities are generated during polishing. To prevent debris from accumulating on the bidirectional lead screw 23 and affecting the threaded engagement between the bidirectional lead screw 23 and the moving plate 22, the fan 444 needs to be turned on. The fan 444 creates a negative pressure at one end of the dust collection hood 442. Through negative pressure adsorption, the generated debris is adsorbed through the dust collection hood 442. Then, the debris enters the dust collection pipe 441 through the dust collection hood 442 and is finally sucked into the dust collection box 443 through the dust collection pipe 441.

[0032] Furthermore, such as Figure 6 As shown, a drive motor 453 is fixedly connected to the top of the end of the rotating frame 42 away from the fourth motor 421. The output shaft of the drive motor 453 is rotatably connected to the rotating frame 42 through a bearing. A horizontal plate 45 is fixedly connected to the output shaft of the drive motor 453. A second electric push rod 451 is fixedly connected to the bottom of the horizontal plate 45. A positioning block 452 is fixedly connected to the output end of the second electric push rod 451.

[0033] During operation, the position held by the adjusting plate 222 is not polished. When polishing is required, the drive motor 453 is turned on, and the output shaft of the drive motor 453 drives the horizontal plate 45 to rotate. The horizontal plate 45 drives the second electric push rod 451 and the positioning block 452 to rotate. When the rotation reaches 180°, it is exactly on the center line of the machine tool 1 and the fixed frame 4. Then the second electric push rod 451 is turned on, and the output end of the second electric push rod 451 drives the positioning block 452 to move, thereby clamping the center of the workpiece. Then, by adjusting the position of the polishing equipment body 432, the edge of the workpiece is polished.

[0034] Furthermore, such as Figure 1 As shown, two cylinders 3 are fixedly connected to the top of the machine tool 1, and a circular plate 31 is fixedly connected to the output end of the two cylinders 3.

[0035] During operation, polishing the edges of the workpiece requires stabilizing the bottom of the workpiece. This is achieved by activating cylinder 3, which drives the circular plate 31 to move through its output end until the circular plate 31 reaches the bottom of the workpiece. Then, the drive motor 453 is activated to adjust the positioning block 452 to its position. Finally, the restrictions imposed by the adjusting plate 222 and the fixed seat 221 are released.

[0036] Working Principle: To solve the problem of inconvenient clamping and polishing of round workpieces, the first motor 21 is turned on. The output shaft of the first motor 21 drives the bidirectional lead screw 23 to rotate, which in turn drives the two moving plates 22. The two moving plates 22 then move the fixed base 221 and the adjusting plate 222 to the appropriate position. The workpiece to be polished is then placed on the fixed base 221. If the workpiece is rectangular, the triangular block 225 rotates away from the adjusting plate 222. The rotating shaft is then fixed by the cross locating pin 227 to facilitate workpiece placement. Finally, the adjusting bolt 223 is rotated to adjust the position of the workpiece. The adjusting plate 222 is moved downwards until the workpiece is clamped and fixed. If the workpiece is round, the triangular block 225 rotates towards the adjusting plate 222, and then the rotating shaft is fixed by the cross positioning pin 227. The round workpiece is clamped onto the fixed seat 221 by the triangular block 225. Then, by rotating the adjusting bolt 223, the adjusting plate 222 is moved downwards until the workpiece is clamped and fixed, thus realizing the function of clamping workpieces of different shapes. Rubber pads are attached to the surfaces of the fixed seat 221, adjusting plate 222, and triangular block 225 that are in contact with the workpiece to be polished to prevent scratches on the workpiece.

[0037] To expand the polishing area, for rectangular workpieces, the fourth motor 421 is activated, and its output shaft drives the reciprocating screw 422 to rotate. The reciprocating screw 422 then moves the moving block 424, thus polishing the horizontal surface of the workpiece. When polishing the width of the workpiece is required, the third motor 41 is activated, and the angle of the rotating frame 42 is adjusted to achieve full polishing of the workpiece. For circular workpieces, the position of the moving block 424 can be adjusted using the fourth motor 421 to determine the polishing radius. Then, the third motor 41 is activated, driving the rotating frame 42 and the moving block 424 to rotate, thus achieving full polishing of the workpiece.

[0038] During polishing, debris and impurities are generated. To prevent debris from accumulating on the bidirectional lead screw 23 and affecting the threaded engagement between the bidirectional lead screw 23 and the moving plate 22, the fan 444 needs to be turned on. The fan 444 creates a negative pressure at one end of the dust collection hood 442. Through negative pressure adsorption, the generated debris is adsorbed through the dust collection hood 442. Then, the debris enters the dust collection pipe 441 through the dust collection hood 442 and is finally sucked into the dust collection box 443 through the dust collection pipe 441.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
