Description

Technical Field

[0001] This invention relates to the field of machining equipment technology, specifically to a four-axis machining center and a clamping base. Background Technology

[0002] Four-axis machining centers are indispensable key equipment in modern machinery manufacturing, widely used in aerospace, automobile manufacturing, mold processing and other fields. They are particularly adept at high-precision milling, drilling and other machining of metal workpieces with complex curved surfaces and polyhedral features. In traditional machining processes, after one or more faces of a workpiece have been machined, it is often necessary to reclamp it to expose and machine the remaining faces.

[0003] However, existing four-axis machining centers still have some shortcomings in practical applications. When processing workpieces requiring multi-faceted machining, manual intervention is usually required after the initial machining to remove the workpiece from the fixture, flip it over, and then perform a second clamping and positioning. This process not only interrupts the continuity of machining and significantly reduces overall production efficiency, but also makes it difficult to guarantee the repeatability of positioning by manual operation, which can easily introduce cumulative errors, thus affecting the machining accuracy and consistency of the final product.

[0004] Furthermore, a large amount of metal debris is inevitably generated during metal cutting. This debris is scattered on the machine tool's worktable, guideways, and workpiece surface. If not cleaned promptly, it will not only affect the processing quality of subsequent processes but may also scratch high-precision guideway surfaces, impacting the machine tool's motion accuracy and service life. Currently, most machine tools rely on external chip removal devices or require operators to stop the machine manually during processing breaks. This method not only increases auxiliary work time but also fails to achieve dynamic cleaning during processing, resulting in unsatisfactory cleaning effects and a harsh working environment. Therefore, integrating automatic workpiece transfer, precise secondary positioning, and efficient automatic cleaning functions into one system to improve processing efficiency and automation levels is a pressing technical problem to be solved in this field.

[0024] Please see the appendix Figure 1 -Appendix Figure 3 A clamping seat applied to the above-mentioned processing machine tool includes: a positioning mechanism 3, which is used to position the product to be processed; The positioning mechanism 3 includes two rotary motors 301, which provide reciprocating rotation power for the entire mechanism. Both rotary motors 301 are fixedly connected to the top of the base 1. The output ends of both rotary motors 301 are fixedly connected to drive plates 302. Fixed bearings 303 are fixedly connected to opposite sides of the two drive plates 302. Clamping plates 304 are fixedly connected to opposite sides of the two fixed bearings 303.

[0025] Please see the appendix Figure 2 and attached Figure 4 A first positioning plate 307 is fixedly connected to the top of the bridge plate 306. The first positioning plate 307 is used for the initial processing of the metal workpiece 311. Two screw seats 308 are fixedly connected to the top of the first positioning plate 307.

The side of the slide rod 317 away from the U-shaped frame 316 is rotatably connected to the clamping plate 319.

[0027] Please see the appendix Figure 1 and attached Figure 11 The top of the base 1 is equipped with a cleaning mechanism 6, which uses the rotational power of the positioning mechanism 3 to clean the debris generated during product processing. The cleaning mechanism 6 includes a collection box 601, which is removable. The collection box 601 is fixedly connected to the bottom of the base 1. Two rack guide rails 602 are fixedly connected to the top of the base 1. The rack guide rails 602 provide a stable sliding base for the two racks 603. The top of each rack guide rail 602 is slidably connected to a rack 603. When the positioning mechanism 3 rotates, the gear ring 305 and the rack 603 cooperate to convert the rotational motion into the linear reciprocating motion of the rack 603. The rack 603 meshes with the gear ring 305. Two mounting shells 604 are fixedly connected between the two racks 603.

[0028] Please see the appendix Figure 12 Several springs 605 are fixedly connected inside the mounting shell 604. The springs 605 apply downward pressure to the limiting plate 606, and press the brushes 609 onto the surface of the base 1 through the connecting plate 607 and the abutment plate 608. The limiting plate 606 is fixedly connected to the bottom of the 605, and the connecting plate 607 is fixedly connected to the bottom of the limiting plate 606. The abutment plate 608 is fixedly connected to the bottom of the connecting plate 607. Several brushes 609 are provided at the bottom of the abutment plate 608. When the mounting shell 604 moves back and forth with the rack 603, the brushes 609, like a broom, collect all the metal debris on the surface of the base 1 into the collection box 601. The limiting plate 606 is slidably connected inside the mounting shell 604, and the connecting plate 607 passes through the bottom of the mounting shell 604.

[0029] Please see the appendix Figure 13 The collection box 601 is externally fixedly connected to a positioning plate 610, which provides a stable mounting base for the fan 611. The fan 611 is externally fixedly connected to the positioning plate 610, and the output end of the fan 611 is fixedly connected to an air duct 612. The top of the air duct 612 is fixedly connected to a blower plate 613. The air force generated by the fan 611 is guided through the air duct 612 to the blower plate 613 above the positioning mechanism 3, which can blow the metal debris scattered on the surface of the bridge plate 306 onto the surface of the base 1.

[0030] Working principle: When machining the metal workpiece 311, it is first placed on top of the first positioning plate 307. After the metal workpiece 311 is fixed by the locking block 310 by turning the screws 309 on both sides, the control cabinet 2 starts the two rotary motors 301 to make the bridge plate 306 start to rotate back and forth. After the moving mounting base 401 moves the controller 405 above the metal workpiece 311, the milling cutter 406 is lowered to perform the first machining. After the first machining is completed, the milling cutter 406 is raised and the mounting base 401 is reset. The control cabinet 2 starts the drive motor 504 to drive the first drive arm 505 to cooperate with the second drive arm 506. The rotary driver 507 then... After the mounting plate 509 moves above the metal workpiece 311, it is lowered to ensure that the two grippers 513 are located on both sides of the metal workpiece 311. Then, the motor 510 is started to bring the two threaded blocks 512 together through the threaded rod 511, which in turn brings the two grippers 513 together to clamp the metal workpiece 311. Then, the mechanical arm picks up the metal workpiece 311 from the first positioning plate 307, and the moving base 502 is started to run along the moving guide rail 501. After the grippers 513 carry the metal workpiece 311 to the top of the second positioning plate 312, the mechanical arm is operated in conjunction with the grippers 513 to place the metal workpiece 311 on the top of the second positioning plate 312. At this point, the electric push rod 315 is activated by the control cabinet 2 to push the U-shaped frame 316 so that the slide rod 317 cooperates with the stabilizing rod 318 to firmly press the clamping plate 319 onto the top of the metal workpiece 311, thus completing the fixing operation of the metal workpiece 311 above the second positioning plate 312. Then, the controller 405 is moved above the metal workpiece 311 by the movable mounting base 401, and the milling cutter 406 is lowered to perform secondary processing.

[0031] During the processing of metal workpiece 311, a large amount of metal debris is generated. Some of the metal debris is scattered on the bridge plate 306. After the fan 611 is started, air is sent to the blowing plate 613 through the air duct 612, and the metal debris on the bridge plate 306 is blown off onto the base 1. When the whole device is working, the rack 603 on the top of the base 1 will move back and forth on the top of the base 1 through the gear ring 305 outside the chuck 304, which drives the two mounting shells 604 to move relative to each other on the top of the base 1. The spring 605 inside the mounting shell 604 provides elastic force to push the connecting plate 607 through the limiting plate 606, so that the abutment plate 608 will put the brush 609 against the top of the base 1 and sweep back and forth, sweeping all the metal debris on the base 1 into the inside of the collection box 601.

[0032] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
