Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of industrial mother machine, and particularly relates to a numerical control machine tool for removing burrs of an agricultural mechanical brake box. BACKGROUND

[0002] The agricultural brake box is usually produced by die casting process, and burrs are easily formed at the splicing positions of the four circular arc edges. Since the local temperature of the die is extremely uneven during die casting, the circular arc edges need to be spliced by multiple dies, the curved surface modeling makes it difficult to uniformly transmit the sealing pressure of the die, a small gap is left at the splicing position, and the high-pressure molten metal penetrates into the cooling position to form burrs. Subsequently, the agricultural brake box with burrs is transferred to the numerical control machine tool for the step of cleaning the burrs, so as to ensure that the circular arc edge contour is regular, the surface is smooth, the design precision is met, the assembly efficiency and equipment sealing performance are improved, the operation and maintenance safety hazards caused by sharp burrs are eliminated, and the equipment reliability in the subsequent use process is ensured.

[0003] In the Chinese patent with the publication number CN117086724A, a continuous burr polishing machine is disclosed. The continuous burr polishing machine includes an operation box, an automatic edge trimmer, transmission wheels, a conveying belt, and a servo motor. The transmission wheels are arranged in an upper line distribution. The transmission wheels are connected by the conveying belt. The outer side wall of the conveying belt is fixedly connected with a plurality of mounting bases. The support arc plate can stably support the flange from the inside corners of the flange. The automatic edge trimmer arranged beside the conveying belt can complete the rapid trimming of the flange. Since the support arc plate is elastically connected with the mounting frame body through the connecting rod and the return spring, it can be suitable for flange processing limiting of various sizes and has a wide range of applications.

[0004] In the above-mentioned patent, although the burrs are removed, some debris and small burrs are attached to the surface of the workpiece during the burr polishing process. The existing cleaning is performed after the workpiece is taken out, so that the attached small burrs and polishing debris are easily dried and stuck in the splicing gap of the brake box circular arc edge. The debris may scratch the polished smooth curved surface during the taking-out process. The subsequent cleaning is difficult to completely remove the stubborn residues, resulting in the workpiece being assembled with other parts, the sealing performance being insufficient, and the workpiece needing to be reworked, thereby reducing the efficiency of workpiece polishing.

[0005] Therefore, we propose a numerical control machine tool for removing burrs of an agricultural mechanical brake box. SUMMARY

[0044] The polishing assembly 327 is provided with two groups, the two groups of polishing assemblies 327 are arranged in staggered symmetry, the two groups of polishing assemblies 327 are movably connected inside the sliding plate 321, the two groups of polishing assemblies 327 work in staggered mode, the two groups of rectangular plates 3271 are both fixedly provided with a third motor 3275 inside, the third motor 3275 is provided with a polishing disc 3276 at the output end, through the two groups of polishing discs 3276 arranged in staggered mode, the burr at the edge of the brake box 4 can be uniformly removed when the sliding plate 321 moves at a constant speed.

[0045] The rectangular plate 3271 is fixedly provided with a self-lubricating silica gel ring 3279 inside, the inner wall of the self-lubricating silica gel ring 3279 is provided with a guide rail 3277, the two ends of the guide rail 3277 are fixedly installed inside the sliding plate 321, the surface of the guide rail 3277 is provided with a gear hole 3278, the surface of the rectangular plate 3271 is fixedly provided with a motor 3272, the outer surface of the rotating rod of the motor 3272 is fixedly provided with a gear tooth 3273, the gear tooth 3273 is matched with the gear hole 3278, the rectangular plate 3271 is located inside the sliding plate 321, and the polishing disc 3276 is located below the sliding plate 321, the gear tooth 3273 moves along the gear hole 3278 through the driving of the motor 3272, so that the rectangular plate 3271 moves along the path of the guide rail 3277, when the rectangular plate 3271 reaches the bending part of the guide rail 3277, the self-lubricating silica gel ring 3279 deforms, so that the rectangular plate 3271 can move along the bending part of the guide rail 3277, and the polishing disc 3276 can be perpendicular to the upper side of the brake box 4, so that the burr at the edge of the brake box 4 is completely polished and removed.

[0046] Specifically, when the burrs of the brake box 4 need to be polished, after the brake box 4 is placed inside the fixing assembly 2, the second motor 313 drives the threaded rod to move the sliding plate 321 at a constant speed through the two side sleeves 326. When the polishing disc 3276 is about to contact the brake box 4, the motor 3272 of the polishing assembly 327 starts the teeth 3273 on the output end rotating rod to move along the tooth hole 3278 on the surface of the guide rail 3277, driving the rectangular plate 3271 to move along the path of the guide rail 3277. Then, the two groups of staggered polishing assemblies 327 work alternately. The third motor 3275 in the rectangular plate 3271 drives the polishing disc 3276 to rotate at high speed, uniformly polishing the burrs of the edge of the brake box 4. At the same time, when the rectangular plate 3271 moves, the gear 3212 inside the sliding plate 321 is engaged with the rack 3274 on one side, driving the gear 3212 to rotate, and then driving the long rod 3213 to rotate through the pinion.

The external air pump provides suction through the first hose 325, and the second hose 328 sprays liquid synchronously. When the rectangular plate 3271 moves to the bending part of the guide rail 3277, the self-lubricating silica gel ring 3279 in the rectangular plate 3271 deforms, ensuring that the rectangular plate 3271 turns smoothly, so that the polishing disc 3276 is always perpendicular to the surface of the brake box 4, completely removing the burrs of the circular arc edge. The reciprocating polyurethane sponge pad 323 cleans the remaining burrs and liquid.
