Description

Technical Field

[0001] The invention relates to the technical field of numerical control processing equipment, in particular to complex curved surface automobile parts manufacturing equipment based on multi-axis numerical control processing technology. Background Art

[0002] Complex curved surface auto parts manufacturing equipment based on multi-axis CNC machining technology can simultaneously control the linkage of multiple coordinate axes. This equipment is particularly suitable for processing molds or product parts with complex geometric shapes, such as automobile engine blades, crankshafts, etc.

[0003] The patent with application number CN201821940469.3 discloses a laser automated water nozzle cutting device for the production of automobile gear covers, including a workbench and a product table. A six-axis robot body and a manipulator removal fixture are arranged on the workbench. An injection mold is arranged on one side of the six-axis robot body. A laser machine and a laser head are arranged on one side of the six-axis robot body. A laser profiling positioning fixture unit is arranged under the laser head. The laser profiling positioning fixture unit includes a positioning fixture support frame. The water nozzle is cut off by laser, which shortens the turnover cycle of turnover packaging that exists in CNC numerical control processing in the prior art, avoids defects such as material chips and scratches caused by cutting the water nozzle by a CNC milling cutter, and improves the product yield.

[0004] In the current manufacturing process, curved automotive parts need to go through multiple fine processes such as milling, grinding, and painting before they can be formed. However, during this process, operators need to frequently transfer workpieces between processes and perform multiple clamping. This not only prolongs the transfer cycle of workpieces between process equipment, but also multiple clamping operations may cause positioning errors to gradually accumulate, which in turn has an adverse effect on the processing accuracy of complex curved automotive parts. In addition, when automotive workpieces are assembled and disassembled in different process equipment, operators often need to extend their arms into the equipment to operate, which is a very cumbersome and inconvenient process.

The accessory fixture placement platform 230 is used to provide a fixed platform for the fixture.

[0057] In this embodiment, Figure 9-12 As shown, the driving device 300 includes a cylinder 310, a pushing part 320 that moves with the telescopic rod of the cylinder 310, a first screw rod 330 that rotates with the movement of the pushing part 320, a lifting partition 340 that moves up and down with the rotation of the first screw rod 330, a second screw rod 350 that rotates with the rotation of the first screw rod 330, a pushing slider 360 sleeved on the outside of the second screw rod 350, and a transmission part 370 arranged at the rear side of the first screw rod 330;

[0058] Specifically, the pushing portion 320 includes a limiting slide bar 321 , a sliding frame 322 slidably connected to the outside of the limiting slide bar 321 , an upper tooth plate 323 disposed on the outer side wall of the sliding frame 322 , and a lower tooth plate 324 disposed below the upper tooth plate 323 .

[0059] Furthermore, the cylinder 310 is fixedly connected to the front end groove wall of the placement groove 112 by bolts, the front and rear ends of the limiting slide rod 321 are clamped and fixed to the groove walls of the front and rear ends of the placement groove 112, the transverse cross-section of the sliding frame 322 is concave and the front end lower convex plate is clamped and fixed to the end of the telescopic rod of the cylinder 310, and the upper tooth plate 323 and the lower tooth plate 324 are both welded and fixed to the outer side wall of the sliding frame 322.

[0060] Furthermore, one end of the first screw rod 330 is rotatably connected to the internal bottom surface of the placement groove 112, and the other end is rotatably connected to the internal top surface of the lifting groove 1220. The bottom end of the first screw rod 330 is clamped with a rod end gear 331, and the rod end gear 331 is engaged with the lower gear plate 324. The center rod of the lifting partition 340 is threadedly connected to the first screw rod 330 and is slidably connected to the interior of the lifting groove 1220.

[0061] Furthermore, the front and rear ends of the second screw rod 350 are respectively rotatably connected to the groove walls at the front and rear ends of the placement groove 112, and the pushing slider 360 is threadedly connected to the outer side of the second screw rod 350. An arc groove 361 matching the size of the arc protrusion 231 is opened on the top surface of the pushing slider 360. A main bevel gear 380 is clamped and fixed on the outer wall of the first screw rod 330, and a secondary bevel gear 390 meshing with the main bevel gear 380 is clamped and fixed at the rear end of the second screw rod 350.

[0062] Furthermore, the telescopic rod of the control cylinder 310 begins to extend, driving the sliding frame 322 in the pushing part 320 to move backward, and the lower tooth plate 324 moving with the sliding frame 322 first contacts the rod end gear 331, driving the rod end gear 331 and the first screw rod 330 to rotate together, and the limit sliding rod 321 in the pushing part 320 is used to limit the moving range of the sliding frame 322;

[0063] After the first screw rod 330 rotates, the lifting partition plate 340 threadedly connected to the outer side of the first screw rod 330 will move upward in the lifting groove 1220, thereby connecting the areas of the fixed warehouse body 121 separated by the partition plate 122.

[0064] At the same time, the main bevel gear 380 on the first screw rod 330 will contact the secondary bevel gear 390, drive the secondary bevel gear 390 to rotate, and drive the second screw rod 350 to rotate, so that the push slider 360 drives the accessory fixture placement table 230 located at the front end of the fixed platform 110 to move toward the inside of the outer jacket device 120. After each rotation of the rotating disk 210, the arc-shaped protrusion 231 on the bottom surface of the accessory fixture placement table 230 will move into the arc-shaped groove 361 on the push slider 360, so that when the push slider 360 moves, it can drive the accessory fixture placement table 230 to move together;

[0065] When the bottom end of the accessory fixture placement platform 230 contacts the groove wall of the docking slide groove 211, the upper tooth plate 323 on the sliding frame 322, which continues to move backward, contacts the rod wall gear 372 and drives it to rotate. At this time, the lower tooth plate 324 no longer conflicts with the rod end gear 331.

[0066] In this embodiment, Fig.13 As shown, the transmission part 370 includes a rotating rod 371, a ratchet 373 that rotates with the rotating rod 371, an outer ring 374 sleeved on the outer side of the ratchet 373, a ratchet pawl 375 disposed in a groove on the inner side of the outer ring 374, and a docking gear 376 that rotates with the outer ring 374;

[0067] Specifically, the upper and lower ends of the rotating rod 371 are respectively rotatably connected to the groove walls of the upper and lower ends of the placement groove 112, and a rod wall gear 372 meshing with the upper gear plate 323 is clamped and fixed on the outer wall of the rotating rod 371, and the end of the rotating rod 371 extends to the inside of the rotating groove 111.

[0068] Furthermore, the ratchet 373 is clamped and fixed at the end position of the rotating rod 371, the outer ring 374 is rotatably connected to the inner bottom surface of the rotating groove 111, the pawl 375 is rotatably connected to the inside of the groove of the inner ring wall of the outer ring 374, and the docking gear 376 is clamped and fixed at the end position of the protruding rod on the top surface of the outer ring 374 and meshes with the fixed ring teeth 220.

[0069] Furthermore, as the rod wall gear 372 rotates, the rotating rod 371 and the ratchet 373 at the end are driven to rotate. When the ratchet 373 collides with the pawl 375, the outer ring 374 and the docking gear 376 are driven to rotate 360°. After the docking gear 376 rotates one circle, it drives the fixed ring gear 220 to rotate 90°, so that by rotating the rotating disk 210 90°, the accessory fixture placement table 230 is moved to the bottom of the placement plate 123 where the processing device is fixed.

[0070] Finally, it should be noted that the cylinder 310 involved in the present invention is a universal standard part or a part known to technical personnel in this field, and its structure and principle can be known to technical personnel through technical manuals or through conventional experimental methods. In the idle space of this device, the cylinder 310 is connected to the external power supply through a wire. The specific connection method should refer to the working principle of the present invention. The electrical connection between each electrical component is completed in a sequential working order, and the detailed connection methods are all well-known technologies in the field.

[0071] The complex curved surface automobile parts manufacturing equipment based on multi-axis CNC machining technology of the present invention is used:

[0072] First, the operator fixes the automobile parts clamping device on the surface of the parts fixture placement table 230 located at the front end of the fixed platform 110, and fixes the curved automobile parts to be processed through the clamping device;

[0073] Subsequently, the telescopic rod of the control cylinder 310 begins to extend, driving the sliding frame 322 in the pusher 320 to move backward, and the lower toothed plate 324 moving with the sliding frame 322 first contacts the rod end gear 331, driving the rod end gear 331 and the first screw rod 330 to rotate together;

[0074] After the first screw rod 330 rotates, the lifting partition plate 340 threadedly connected to the outer side of the first screw rod 330 moves upward in the lifting groove 1220, thereby connecting the areas of the fixed bin body 121 separated by the partition plate 122;

[0075] At the same time, the main bevel gear 380 on the first screw rod 330 contacts the secondary bevel gear 390, driving the secondary bevel gear 390 to rotate, thereby driving the second screw rod 350 to rotate, and then the push slider 360 drives the accessory fixture placement table 230 located at the front end of the fixed platform 110 to move toward the inside of the outer cover device 120;

[0076] When the bottom end of the accessory fixture placement platform 230 contacts the groove wall of the docking slide groove 211, the upper tooth plate 323 on the sliding frame 322 that continues to move backward contacts the rod wall gear 372 and drives it to rotate, and at this time, the lower tooth plate 324 no longer conflicts with the rod end gear 331;

[0077] As the rod wall gear 372 rotates, the rotating rod 371 and the ratchet 373 at the end are driven to rotate. When the ratchet 373 contacts the pawl 375, the outer ring 374 and the docking gear 376 are driven to rotate, and then the fixed ring gear 220 is driven to rotate 90 degrees, so that the accessory fixture placement table 230 is moved to the bottom of the placement plate 123 where the processing device is fixed by rotating the rotating disk 210 by 90 degrees;

[0078] After that, the telescopic rod of the control cylinder 310 begins to retract. At this time, the upper tooth plate 323 drives the rod wall gear 372 to rotate, and the ratchet 373 and the pawl 375 bend in the same direction, so that the position of the outer ring 374 remains fixed, and the contact between the lower tooth plate 324 and the rod end gear 331 restores the position of the lifting partition 340 and the accessory fixture placement table 230;

[0079] By repeating the above operations, the processing and manufacturing of curved surface automobile parts can be completed in batches.
