Description

Technical Field

[0001] This utility model relates to the field of machining platform technology, specifically a machining platform for a five-axis CNC machine tool. Background Technology

[0002] In the field of machining, five-axis CNC machine tools play a crucial role as high-precision machining equipment. These machines integrate advanced technology and precision control, enabling five-axis simultaneous machining of complex-shaped workpieces, making them highly sought after. However, in practical applications, common five-axis CNC machine tool machining platforms still face some unresolved issues.

[0003] First, common machining platforms require frequent changes of different clamps on the gripping table and adjustments to the workpiece's height and rotation during component processing. However, clamp changeovers are often cumbersome, and the gripping table itself struggles to flexibly adjust clamp positions, resulting in poor adjustability and inconvenience for operators, thus reducing work efficiency. Second, machining processes generate a large amount of debris and dust residue on the platform, requiring cleaning with a dust pump. However, since machining platforms are often made of cast iron, debris easily adheres to their surface, making effective cleaning difficult. This not only increases maintenance complexity but may also affect the accuracy and quality of subsequent machining. Utility Model Content

[0024] Please see Figure 1-6 ,

[0025] A machining platform for a five-axis CNC machine tool includes a mounting base plate 1. A fixing ring 2 is mounted on the bottom of the mounting base plate 1. A disc 3 is disposed inside the fixing ring 2. A first motor 4 is mounted on the top of the disc 3. A fixed seat 16 is mounted on the bottom of the disc 3. A bidirectional bolt 5 is disposed on the top of the mounting base plate 1. The bidirectional bolt 5 is connected to the output end of a second motor 6. The second motor 6 is installed inside the mounting base plate 1. Two moving blocks 7 are disposed on the bidirectional bolt 5. A telescopic cylinder 8 is disposed on the top of the moving blocks 7. A fixed plate 9 is disposed on the top of the telescopic cylinder 8. Four limit rods 10 are disposed on the top of each moving block 7. A stabilizing ring 11 is disposed on the top of the fixed plate 9. A first lead screw 12 is disposed on the fixed plate 9. The two ends of the first lead screw 12 are respectively connected to a rotating handle 13 and a clamping mechanism 14. A dust removal device 15 is disposed on the top left end of the mounting base plate 1.

[0026] In this example, the top of the mounting base plate 1 is provided with a sliding groove that cooperates with two moving blocks 7 and bidirectional bolts 5. The fixing ring 2 is installed at the center of the bottom of the mounting base plate 1, and the inside of the fixing ring 2 is provided with a circular through groove that cooperates with the disc 3. The top of the fixing seat 16 is provided with a stepped shape for installation on the bottom of the disc 3. The top left end of the mounting base plate 1 is provided with a mounting hole that cooperates with the dust removal device 15.

[0027] It should be noted that the chute not only ensures that the moving block 7 can move smoothly along the predetermined trajectory, but also ensures that the bidirectional bolt 5 can drive the moving block 7 to achieve precise displacement when rotating through precise size and shape design.

[0028] In this example, the bidirectional bolt is installed inside the slide groove set on the top of the mounting base plate 1. The second motor 6 is installed at the rightmost end of the slide groove and connected to the bidirectional bolt 5. Two moving blocks 7 are symmetrically installed at both ends of the bidirectional bolt 5. The moving blocks 7 are provided with threaded through holes that cooperate with the two ends of the bidirectional bolt 5. Limit rods 10 are provided at the four corners of the top of the moving blocks 7.

[0029] It should be noted that the two moving blocks 7 are symmetrically installed at both ends of the bidirectional bolt 5. This design not only maintains the balance and stability between the moving blocks 7, but also improves the load-bearing capacity of the entire machining platform. The threaded through holes on the moving blocks 7 fit tightly with both ends of the bidirectional bolt, ensuring the stability and accuracy of the moving blocks 7 during movement.

[0030] In this example, the bottom of the telescopic cylinder 8 is fixedly installed on the top of the moving block 7 and is located in the middle of the four limiting rods 10. The bottom of the fixed plate 9 is fixedly installed on the output end of the telescopic cylinder 8. The four limiting rods 10 are T-shaped and pass through the fixed plate 9. A stabilizing ring 11 is provided in the middle of the top of the fixed plate 9. The stabilizing ring 11 is passed through by the first lead screw 12, and the stabilizing ring 11 and the first lead screw 12 are rotatably connected.

[0031] It should be noted that this design not only ensures the stability and accuracy of the telescopic cylinder 8 when driving the fixed plate 9 to move, but also avoids interference between the telescopic cylinder 8 and the limit rod 10, thus ensuring the smooth operation of the entire mechanism.

[0032] In this example, the clamping mechanism 14 consists of a fixed frame 1401, a clamping plate 1402, and a second lead screw 1403. The fixed frame is connected to the end of the first lead screw 12 away from the rotating handle 13. The clamping plate 1402 is installed inside the fixed frame. The second lead screw 1403 passes through the top of the fixed shell and is connected to the top of the clamping plate 1402. The top of the fixed frame 1401 is provided with a threaded through hole that mates with the second lead screw 1403.

[0033] It should be noted that the fixed frame is firmly fixed to the end of the first lead screw 12 away from the rotating handle 13, serving as a support and connecting component of the clamping mechanism 14. The design of the fixed frame not only ensures a reliable connection between the clamping mechanism 14 and the first lead screw 12, but also provides it with a stable support foundation.

[0034] In this example, the dust removal device 15 consists of a movable plate 1501, two hinge seats 1502, a housing 1503, a handle 1504, three fans 1505, three third motors 1506, and three support frames 1507. The movable plate 1501 is fixedly installed in the preset mounting hole at the top left end of the mounting base plate 1. The two hinge seats 1502 are respectively installed at the front and rear ends of the movable plate 1501. The rightmost end of the housing 1503 is installed on the hinge seat 1502. The handle 1504 is installed at the leftmost end of the housing 1503. The three fans 1505 and the three third motors 1506 are installed inside the housing 1503 through the three support frames 1507, and the housing 1503 is provided with three through holes that cooperate with them.

[0035] It should be noted that the dust removal device 15, as an important auxiliary component of the machining platform for a five-axis CNC machine tool, is mainly intended to remove dust and debris generated during the machining process in a timely manner, so as to maintain the cleanliness of the machining environment and the quality of the workpiece.

[0036] In summary: When using this platform, first start the second motor 6 and adjust the distance between the two moving blocks 7 according to the length of the part. Then place both ends of the part in the fixed frame 1401 and control the clamping plate 1402 by rotating the second lead screw 1403 to firmly clamp and fix the part. If it is necessary to adjust the orientation of the part, start the first motor 4 to drive the mounting base plate 1 and the fixing ring 2 to rotate around the disc 3, thereby realizing the rotation of the part in the horizontal direction. At the same time, the telescopic cylinder 8 equipped on the top of the moving block 7 can control the lifting and lowering of the part by starting the cylinder to realize the vertical height adjustment. When it is necessary to clean the platform surface, the housing 1503 and the moving plate 1501 can be pulled out from the mounting hole by the handle 1504. Rotate the housing 1503 to a position perpendicular to the platform using the hinge seat 1502, and then start the third motor 1506 to drive the fan 1505 to blow off and clean the iron filings on the platform surface. After cleaning, reset the housing 1503 and push it back into the mounting hole to ensure that the device is neatly stored and does not take up extra space.

[0037] Beneficial Effects: This five-axis CNC machine tool's machining platform, through the design of a fixed ring, a two-way lead screw, and a telescopic cylinder, allows for the positional adjustment of two moving blocks and the parts above them via the rotation of the two-way bolts, thus quickly clamping and fixing the workpiece. Simultaneously, the first motor drives the fixed ring to rotate around the disc, enabling slow rotational adjustment of the fixed workpiece to meet multi-angle machining needs. Furthermore, the telescopic cylinder's telescopic function allows for height adjustment of the fixed plate and the clamping mechanism mounted on it, further enhancing the device's adaptability to different workpieces and its machining flexibility. The dust removal mechanism is designed so that when cleaning is required, the housing is pulled out of the mounting hole via the hinge and rotated to a position perpendicular to the machining platform. Subsequently, the third motor drives the fan to blow iron filings and debris from the platform surface to a designated location. After cleaning, the housing is reset via the hinge and pushed back into the mounting hole, making the left end of the housing flush with the left end of the platform, thus neatly storing the dust removal device and avoiding unnecessary space occupation.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
