[0002] CNC lathe is one of the most widely used CNC machine tools. It is mainly used for cutting inner and outer cylindrical surfaces of shaft parts or disk parts, inner and outer conical surfaces of arbitrary taper angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads. It can also perform grooving, drilling, reaming, reaming and boring, etc.

[0003] At present, when processing metal workpieces such as sound tubes, most CNC machine tools first fix the workpiece on the machine table, and then use the processing head on it to perform processes such as drilling, cutting, and grinding on the workpiece. However, when multi-sided processing of the workpiece is required, the workpiece needs to be repeatedly removed from the fixture and rotated to the surface to be processed for processing. The operation is complicated and the processing efficiency is low.

[0004] For example, the Chinese invention patent (publication number: CN117140079A) discloses a "six-axis CNC deburring device". Its specification discloses that after the workpiece is processed on the machine tool, it usually needs to be removed from the fixture and then placed on the grinding equipment for grinding. It is impossible to achieve integrated processing and grinding operations for the workpiece, and it is impossible to meet the grinding requirements of different precisions, which is not conducive to improving the surface quality of the workpiece. The above patent can prove the defects of the existing technology.

[0005] Therefore, we have made improvements to this problem and proposed a multi-table combined sound pipe CNC processing equipment. Summary of the invention

[0024] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0025] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0026] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0027] Example 1, please refer to Figure 1-Figure 8A multi-table combined sound pipe CNC processing equipment, wherein a spline shaft 407 is fixedly connected to the output shaft of the second motor 402, and a first spring 408 is arranged on the spline shaft 407. The spline shaft 407 is interlaced and connected with the middle part of the round frame 403. By arranging the spline shaft 407 and the first spring 408, when the output shaft of the second motor 402 rotates, the round frame 403 and the brush rod 405 can be driven to rotate, and the bottom of the workpiece is polished and deburred. When there is no ventilation in the first telescopic rod 410, the brush rod 405 can be kept flush with the arc rod 422, so that the two brush rods 405 and the arc iron block 404 can push the arc rod 422 under the action of the electromagnet 406, so that the support frame 303 can move.

[0028] The circular frame 403 is internally slidably connected to two arc-shaped iron blocks 404, one side of the arc-shaped iron block 404 is fixedly connected to one end of an adjacent brush rod 405. By providing the arc-shaped iron block 404, the brush rod 405 will not be separated from the circular frame 403 and can rotate well.

[0029] The front and rear sides of the circular frame 403 are fixedly connected with an electromagnet 406 used in conjunction with the arc-shaped iron block 404. A third spring 423 is arranged between the electromagnet 406 and the arc-shaped iron block 404. By arranging the third spring 423 and the electromagnet 406, the electromagnet 406 can attract the arc-shaped iron block 404 when energized, so that the arc-shaped iron block 404 and the brush rod 405 can push the arc-shaped rod 422. When the electromagnet 406 is not energized, the arc-shaped iron block 404 and the brush rod 405 can be reset to the initial position under the action of the third spring 423.

[0030] The front and rear sides of the top of the disc 401 are fixedly connected to a first telescopic rod 410, and the top of the first telescopic rod 410 is fixedly connected to an arc plate 411 for supporting the circular frame 403. By setting the first telescopic rod 410 and the arc plate 411, the processing head 2 will squeeze the elastic telescopic tube 419 during the movement, so that the gas in the elastic telescopic tube 419 enters the disc 401 through the air pipe 416, and then enters the interior of the first telescopic rod 410, so that the first telescopic rod 410 is extended to lift the circular frame 403, so that the brush rod 405 and the arc rod 422 are not located in the same plane, so that the brush rod 405 can be flexibly rotated to grind the bottom of the workpiece and perform deburring.

[0031] A rectangular groove 418 is provided on the front side of the frame 1, and an air pipe 416 is fixedly connected to one side of the disc 401. One end of the air pipe 416 is connected to an air valve 417. The air valve 417 is installed at one end of the frame 1 and is connected to the rectangular groove 418. By providing the air valve 417, people can adjust the gas content inside the elastic telescopic tube 419, the air pipe 416, the disc 401, the first telescopic rod 410 and the second telescopic rod 412 by disassembling the air valve 417, so as to avoid poor adjustment effect due to gas leakage during long-term use.

[0032] An elastic telescopic tube 419 is arranged inside the rectangular groove 418, one end of the elastic telescopic tube 419 is fixedly connected to a connecting block 420, one end of the connecting block 420 is fixedly connected to one side of the processing head 2, and a second spring 421 for resetting the elastic telescopic tube 419 is arranged inside the elastic telescopic tube 419. By arranging the elastic telescopic tube 419, the elastic telescopic tube 419 on both sides can be compressed or stretched during the movement of the processing head 2, so that the gas in the elastic telescopic tube 419 is filled into the disc 401, the first telescopic rod 410 and the second telescopic rod 412, or the gas in the disc 401, the first telescopic rod 410 and the second telescopic rod 412 enters the interior of the elastic telescopic tube 419, thereby increasing the utilization of the gas.

[0033] The rear side of the disc 401 is fixedly connected to a second telescopic rod 412, one end of which is fixedly connected to a push plate 413. By setting the second telescopic rod 412, after the gas enters the disc 401 through the air pipe 416, the gas can push the second telescopic rod 412 to extend, thereby allowing the push plate 413 and the inclined plate 414 to move, so that the chain 502 and the mesh conveyor belt 501 can rotate, and the processing waste accumulated on the mesh conveyor belt 501 can fall into the recycling box 503 as the mesh conveyor belt 501 rotates, which is convenient for people to recycle and sort the waste, reduces people's labor intensity, and utilizes the movement of the processing head 2 to recover the waste.

[0034] Both sides of the bottom end of the push plate 413 are hinged with inclined plates 414, and a spring plate 415 is arranged between the inclined plate 414 and the push plate 413. By setting the spring plate 415, when the push plate 413 and the inclined plate 414 move forward and backward, the inclined plate 414 will only engage with the chain 502 when moving forward, and will not engage with the chain 502 during the resetting process, which is convenient for collecting waste chips.

[0035] Please refer to Figure 1 and Figure 7The collecting mechanism 5 includes a mesh conveyor belt 501 arranged on the top of the machine table 301 through multiple rollers, and chains 502 used in conjunction with the inclined plate 414 are fixedly connected to both sides of the mesh conveyor belt 501. A recycling box 503 for recycling waste chips on the mesh conveyor belt 501 is interspersed on the front side of the machine table 301. By setting up the collecting mechanism 5, the processed waste chips can fall on the mesh conveyor belt 501, and under the action of the inclined plate 414, it continuously rotates, so that the waste chips can continuously fall into the recycling box 503 for recycling, making the entire table surface tidier.

[0036] The use process of the multi-table combined sound pipe CNC processing equipment provided by the present invention is as follows: First, the workpiece is placed between the plurality of electric push rods 307, such as Figure 1 As shown, the electric push rod 307 is controlled to extend to clamp the workpiece, and one of the electromagnets 406 is controlled to be energized, so that the two adjacent arc-shaped iron blocks 404 are attracted by the magnetic force of the electromagnet 406. Figure 4 As shown, the brush rod 405 squeezes the arc rod 422, driving the support frame 303 to move to the bottom of the frame 1, and the electromagnet 406 is powered off. When the processing head 2 approaches the machine table 301, it squeezes the corresponding elastic telescopic tube 419. The gas in the elastic telescopic tube 419 enters the inside of the disc 401 through the air pipe 416, and finally leads to the first telescopic rod 410 and the second telescopic rod 412. The second telescopic rod 412 lifts the round frame 403, so that the brush rod 405 and the arc rod 422 are not located in the same plane. The push plate 413 and the inclined plate 414 drive the chain 502 and the mesh conveyor belt 501 to rotate, and the processing head 2 is controlled to process the workpiece. After processing one surface, the output shaft of the reducer 306 can be controlled to rotate. The other side of the workpiece is turned toward the processing head 2. When the processing head 2 continues to process the workpiece, the output shaft of the second motor 402 is controlled to rotate. The second motor 402 drives the circular frame 403 and the brush rod 405 to rotate, and the processed surface of the workpiece is polished and deburred. When the workpiece is completely processed, the processing head 2 is controlled to move to another machine table 301. At this time, the elastic telescopic tube 419 is extended, the gas returns to the elastic telescopic tube 419, the circular frame 403 is reset, and the other elastic telescopic tube 419 is contracted, and then another electromagnet 406 is controlled to attract the arc iron block 404 and squeeze the other arc rod 422, so that the processed workpiece is moved out of the processing position of the processing head 2 along with the support frame 303, so that people can remove the workpiece easily.
