Description

Technical Field

[0001] The present invention relates to the technical field of component processing machine tools, and more particularly to a multi-axis machine tool for automobile component processing. Background Art

[0002] The processing of automobile components is mostly completed by machine tools. However, the machine tools can only perform single-axis or double-axis processing. When processing complex processes, it is necessary to clamp and adjust the reference surface of the components multiple times, which increases the processing time. Due to multiple clamping and conversion of the reference surface, it is easier to introduce errors during the processing of the components, resulting in low processing accuracy. To complete complex processing tasks, multiple machine tools need to work together, which increases the floor area of the machine tools and the labor intensity of the operators.

[0003] Although existing numerical control machine tools can improve the processing accuracy of components, they cannot adjust the positions of components in multiple axial directions and cannot adjust the flipping angles of components. To achieve multi-axis adjustment, operators still need to continuously adjust and convert the reference surface of the components. The labor intensity of the operators has not been reduced, and due to multiple adjustments and conversions of the reference surface of the components, there are always errors in the component processing, affecting the processing efficiency and other problems.

[0004] Therefore, the present application provides a multi-axis machine tool for automobile component processing to solve the problems raised in the above background art. Summary of the Invention

The turning mechanism 4 symmetrically clamps the parts through the jaws 46 and processes them through the tool head 55 above; the turning mechanism 4 further includes a column 41, a shaft seat 43 is fixed on the top surface of the column 41, a bushing 44 is adaptively installed through the body of the shaft seat 43 horizontally, a lead screw 45 is adaptively installed in the inner cavity of the bushing 44, and a fastening ring 47 and a turntable mechanism 48 are successively and adaptively sleeved on the side of the lead screw 45 close to the jaws 46. Specifically, the machine tool realizes displacements in multiple axial directions of up, down, left, right, front and back through the vertical slide mechanism 5, the transverse slide mechanism 3 and the longitudinal slide mechanism 2, and thus realizes multi-axis processing. A driving structure 54 is arranged on the vertical slide mechanism 5. The driving structure 54 is an existing product on the market and will not be elaborated here. A tool head 55 is installed on the driving structure 54, and the tool head 55 performs processing operations on the parts symmetrically clamped on the turning mechanism 4. The multi-axis machine tool cooperates with each other and moves in coordination among the longitudinal slide mechanism, the vertical slide mechanism, the transverse slide mechanism and the turning mechanism to complete the processing of multiple reference planes of the parts and improve the processing accuracy of the parts; by controlling the movements in multiple axial directions, the processing operations of parts with complex shapes are realized.

[0042] As Figures 5 - 10 , Figure 13 , Figure 14As shown, in this embodiment, the turntable mechanism 48 also includes a turntable 481, which is adapted to be embedded on the outer annular surface of the turntable mechanism 48. A connecting block 486 is arranged on the outer arc surface of the turntable 481 body. The connecting block 486 is adapted to be connected to the fixing block 484 through a wire lever 485. The fixing block 484 is arbitrarily fixed on the outer annular surface of the turntable mechanism 48 body. The rotation of the wire lever 485 drives the turntable 481 to rotate and displace. At least three support shafts 483 are arranged on the annular surface of the turntable 481 body. The support shafts 483 are adapted to be installed on the annular surface of the turntable A482 body. The turntable A482 and the turntable 481 are arranged vertically relative to each other, and the distance between the turntable A482 and the turntable 481 is at least 3 cm. Specifically, the main body of the turntable mechanism 48 is a ring disk with a perforation in the middle, and a turntable 481 is arranged on the ring surface away from the perforation. A connecting block 486 is fixed on the outer arc surface of the turntable 481 body, and the connecting block 486 is adapted to the rotation displacement of the wire lever 485. The wire lever 485 body is movably adapted to the fixed block 484, and the fixed block 484 is fixed on the outer ring surface of the turntable mechanism 48 body. The turntable 481 is driven to rotate by rotating the wire lever 485, and the turntable 481 body ring surface is rotated. Three support shafts 483 are arranged on the top, and a turntable A482 is installed on the support shaft 483. Both the turntable A482 and the turntable 481 are annular bodies. The turntable 481 and the turntable A482 are arranged vertically, and are supported and spaced by three equidistant support shafts 483. By rotating the turntable 481, the main driving arm 496, the driven arm 494 and the driven arm A495 are displaced and gathered to drive the wire shaft 45 to rotate, and the rotation of the wire shaft 45 itself drives the parts to rotate or adjust the angle.

[0043] Furthermore, the ring surface between the turntable 481 and the turntable A482 is adapted to clamp the rotating block 489, the rotating block 489 is fixed by the central axis 492, the rotating block 489 is located between two adjacent support shafts 483, the rotating block 489 body is a through-hole structure, and at least three rotating blocks 489 are provided, the main driving arm 496 is installed in the inner cavity of any rotating block 489 body, and the driven arm 494 and the driven arm A495 are installed in the inner cavities of the other two rotating blocks 489 bodies. Specifically, three rotating blocks 489 are clamped equidistantly between the turntable 481 and the turntable A482, and the rotating block 489 is a horizontal through structure, and the main driving arm 496, the driven arm 494 and the driven arm A495 are respectively adapted to be installed in the three rotating blocks 489. The main driving arm 496 is mounted in the inner cavity of the rotating block 489 body, and the main driving arm 496 slides in the rotating block 489 body. The rotating block 489 is respectively fixed on the annular surface of the turntable 481 and the annular surface of the turntable A482 through the central axis 492; the inner cavities of the two rotating blocks 489 bodies are respectively mounted with the driven arm 494 and the driven arm A495, and the driven arm 494 and the driven arm A495 slide in their respective rotating blocks 489, and the fixing method and positional relationship of the two rotating blocks 489 are the same as those of the rotating block 489 on the main driving arm 496. The main driving arm 496, the driven arm 494 and the driven arm A495 are displaced by the turntable 481 to move, gather and tightly abut the wire shaft 45, so that the wire shaft 45 is in a clamping, supporting and positioning state. The main driving arm 496, the driven arm 494 and the driven arm A495 clamp and release the wire shaft 45 through the displacement of the turntable 481. The main driving arm 496, the driven arm 494 and the driven arm A495 drive the clamped and abutted wire shaft 45 to rotate itself, thereby realizing 360-degree flipping of the parts and adjustment of the angles of the parts themselves.

[0044] like Figures 8 - 10 , Figure 13 , Figure 14As shown in the figure, in this embodiment, one end of the main drive arm 496 body passes through the turntable mechanism 48 through the output shaft 4960 and is connected to the drive motor 497. A through hole A4961 is provided in the main drive arm 496 body. A shaft rod 4964 is adaptively installed in the through hole A4961. Bevel gears A4963 are respectively installed at both ends of the shaft rod 4964 body. The bevel gear A4963 is adaptively connected to the bevel gear B4965, and the bevel gear B4965 is connected to the output shaft 4960; the bevel gear A4963 at the other end is adaptively connected to the bevel gear 4962, and the bevel gear 4962 is in abutting connection with the roller 490 and is integrally formed.The rear end of the main driving arm 496 body is connected to the driving motor 497. The driving motor 497 is an existing product on the market and will not be elaborated here. The output shaft 4960 of the driving motor 497 penetrates through the turntable mechanism 48 body. A through hole A4961 is provided in the main driving arm 496 body. A shaft rod 4964 is adaptively installed in the through hole A4961. Two bevel gears A4963 are respectively installed at both ends of the shaft rod 4964 body. One bevel gear A4963 is adapted to the output shaft 4960, and the other bevel gear A4963 is adapted to the bevel gear 4962. The bevel gear 4962 is in abutting connection with the roller 490 and is integrally formed. The roller 490 on the main driving arm 496 is driven to rotate by the driving motor 497. In this embodiment, the driven arm 494 and the driven arm A495 can also rotate independently in the same way as the rotation principle and structure of the roller on the main driving arm 496. The turntable 481 and the turntable A482 are both circular ring plate structures. Through holes 498 are respectively provided in the middle parts of the turntable 481 and the turntable A482 bodies. The front ends of the main driving arm 496, the driven arm 494, and the driven arm A495 bodies in the through hole 498 area are respectively installed with rollers 490. The rollers 490 of the driven arm 494 and the driven arm A495 bodies are respectively fixed by the wheel shafts 493. The rollers 490 on the main driving arm 496, the driven arm 494, and the driven arm A495 bodies are respectively adapted to the wire shafts 45. Half of the wire shaft 45 body is a threaded wire (not shown in the figure), and the other half of the wire shaft 45 body is several independent wheel grooves 49. The threaded wire is adapted to the fastening ring 47 and the tooth 461. The several independent wheel grooves 49 are vertically adapted to the rollers 490. The rear end of the main driving arm 496 body is nested in the disk shaft 491 through the output shaft 4960 and is connected to the driving motor 497. The rear ends of the driven arm 494 and the driven arm A495 bodies are respectively fixed on the outer circumferential surface of the turntable mechanism 48 through the disk shaft 491. The rollers 490 on the main driving arm 496, the driven arm 494, and the driven arm A495 bodies are respectively vertically adapted to the wire shafts 45. The front half section of the wire shaft 45 body is a threaded wire. By rotating the fastening ring 47, the fastening ring 47 drives the tooth 461 to rotate, thereby realizing the expansion and closing of the clamping jaw 46. The rear half section of the wire shaft 45 body is several independent wheel grooves 49. The rollers 490 in the wheel grooves 49 are vertically adapted. The rotation of the rollers 490 drives the rotation of the wire shaft 45, thereby realizing the rotation of the parts clamped on the wire shaft 45. This rotation method is simply and exquisitely designed, and can realize 360-degree rotation of the parts and micro-adjustment of the part angles. This flipping mechanism has the advantages of simple design and low manufacturing cost.

[0045] Such as Figure 8 , Figure 11 , Figure 12As shown in the figure, in this embodiment, there is at least a 1 cm gap between the outer ring surface of the turntable A482 body and the fastening ring 47. A perforation 442 is provided in the middle of the fastening ring 47 body. A wire shaft 45 is adaptively installed in the perforation 442. The wire shaft 45 is adapted to the tooth 461 at the tail end of the jaw 46. The tooth 461 is adaptively clamped and fixed by two clamping pieces 441. The clamping pieces 441 are arranged on the wall surface of the fastening ring 47 body close to the jaw 46 away from the perforation 442. Three groups of clamping pieces 441 are evenly arranged on the fastening ring 47 in each group. The three groups of clamping pieces 441 respectively and movably clamp the same jaw 46. The jaw 46 is used to clamp components. Specifically, there is at least a 1 cm gap between the outer ring surface of the turntable A482 body and the fastening ring 47, which facilitates the user to rotate the fastening ring 47. The setting of the gap prevents the linkage between the fastening ring 47 and the turntable A482. Three groups of equidistant clamping pieces 441 are fixedly arranged on the fastening ring 47 body. Each group of clamping pieces 441 is adapted to clamp the tail end of the jaw 46. The tooth 461 at the tail end of the jaw 46 body is adapted to the thread at the front end of the wire shaft 45 body. By rotating the fastening ring 47, the displacement of the tooth 461 is driven, and the jaw 46 is tightened and closed, thereby realizing the clamping of components. The jaw 46 is of a claw-shaped structure, which can better adapt to the clamping of various components or special-shaped components and meet the requirements of different scenarios.

To achieve multi-axis machining of the machine tool, two slide rails B52 are symmetrically arranged on the wall of the control cabinet 51 on one side of the transverse slide table mechanism 3. A number of fixing holes 53 are evenly arranged on the body of the slide rail B52. The fixing holes 53 are adapted to screws to fix the slide rail B52. The body of the slide rail B52 is adapted to a driving structure 54, and a tool head 55 is installed at the bottom of the driving structure 54. The vertical slide table mechanism 5 is an existing product on the market, and its internal structure will not be elaborated here. The vertical slide table mechanism 5 realizes the up-and-down movement adjustment of the driving structure 54 through the slide rail B52. The displacement of the driving structure 54 drives the displacement of the tool head 55 to realize the machining of multiple areas and the reference plane of the tool head 55. The longitudinal slide table mechanism 2 further includes a slide table 22. The bottom of the slide table 22 body is adapted to a slide rail 23. The slide rail 23 is longitudinally located on the convex platforms 12 extending upward on both sides of the groove 11 of the base 1 body. A longitudinal motor 21 is adaptively installed in the groove 11. The shaft of the longitudinal motor 21 is connected to a lead screw 24, and the lead screw 24 drives the slide table 22 to perform longitudinal displacement. The longitudinal slide table mechanism 2 is an existing product on the market, and its internal structure will not be elaborated here. By driving the lead screw 24 through the output shaft of the longitudinal motor 21, the lead screw 24 drives the slide table 22 to realize the front-and-back displacement and adjustment, and further realize the front-and-back displacement of the parts. The transverse slide table mechanism 3 further includes a slide table A34. The bottom of the slide table A34 body is adapted to a slide rail A33. The slide rail A33 is transversely located on the convex platforms A26 extending upward on both sides of the groove A25 of the slide table 22 body. A transverse motor 31 is adaptively installed in the groove A25. The shaft of the transverse motor 31 is connected to a lead screw A32, and the lead screw A32 drives the slide table A34 to perform transverse displacement. The transverse slide table mechanism 3 is an existing product on the market, and its internal structure will not be elaborated here. By driving the lead screw A32 through the output shaft of the transverse motor 31, the lead screw A32 drives the slide table A34 to realize the left-and-right displacement and adjustment, and further realize the left-and-right displacement of the parts. Two flipping mechanisms 4 are symmetrically installed on the slide table A34. The flipping mechanism 4 realizes the 360-degree rotation or flipping of the parts. The machine tool completes the machining of multiple reference planes of the parts through the mutual cooperation and coordinated displacement among the longitudinal slide table mechanism, the vertical slide table mechanism, the transverse slide table mechanism, and the flipping mechanism, improving the machining accuracy and machining efficiency of the parts.

[0047] The present invention also provides the working principle of a multi-axis machine tool for machining automotive parts: The user clamps the part in the symmetrically arranged flipping mechanism 4. First, rotate the fastening ring 47, and the fastening ring 47 drives the wire shaft 45 to move back and forth, thereby clamping the part firmly on the jaws 46. Several teeth 461 are integrally formed at the tail end of the jaws 46, and the teeth 461 are adapted to the thread on the main body of the wire shaft 45. By rotating and displacing the fastening ring 47, the tightening and loosening of the jaws are realized. When the fixed part is under machining operation, the user can control the longitudinal slide mechanism 2, the vertical slide mechanism 5, and the transverse slide mechanism 3 according to the machining requirements of the part, so as to realize the adjustment of the part in six directions of front, back, up, down, left, and right. The part is clamped once to realize the machining of multiple reference planes. By controlling multiple axial movements, the machining of parts with complex shapes can be realized. Compared with the traditional single-axis or double-axis machining methods, this machine tool is more flexible and has higher machining accuracy. Two flipping mechanisms 4 are symmetrically arranged horizontally and linearly on the slide A34 in the transverse slide mechanism 3. The flipping mechanism 4 further includes a column 41. A shaft seat 43 is fixed on the top surface of the column 41. A sleeve 44 is adaptively installed through the main body of the shaft seat 43 horizontally. A wire shaft 45 is adaptively installed in the inner cavity of the sleeve 44. A fastening ring 47 and a turntable mechanism 48 are successively and adaptively sleeved on the wire shaft 45 on the side close to the jaws 46. The turntable mechanism 48 further includes a turntable 481 and a turntable A482. The centers of the turntable mechanism 48, the turntable 481, and the turntable A482 are perpendicular to each other, and three rollers 490 are arranged in the central through hole 498. The three rollers 490 are respectively installed at the front ends of the main driving wall 496, the driven arm 494, and the driven arm A495. The three rollers 490 vertically abut against the rear section of the main body of the wire shaft 45 and are provided with a plurality of wheel grooves 49. The three rollers 490 drive the rotation of the wire shaft 45. The rotation of the wire shaft 45 further drives the part on the jaws 46 at the front section of the wire shaft 45 to rotate or flip 360 degrees, thereby realizing the machining of multiple reference planes of the part itself and the machining of parts with complex shapes. The main driving wall 496, the driven arm 494, and the driven arm A495 can be driven by the wire lever 485 on the turntable 481. The rotational displacement of the turntable 481 realizes the separation and convergence of the three rollers 490, thereby facilitating the replacement of wire shafts 45 with different diameters, so as to realize the clamping of multiple parts or multiple non-standard parts and meet the requirements of different scenarios. This flipping mechanism is simply and exquisitely designed and has a low manufacturing cost, which can meet the needs of different users and different scenarios. And this machine tool completes the machining of multiple reference planes of the part through the mutual cooperation and coordinated displacement among the longitudinal slide mechanism, the vertical slide mechanism, the transverse slide mechanism, and the flipping mechanism, improving the machining accuracy and machining efficiency of the part.
