Description

Technical Field

[0001] This invention belongs to the field of CNC drilling machine tool technology, specifically a CNC drilling machine tool with a chip collection and cleaning function. Background Technology

[0002] CNC machine tools, short for numerical control machine tools, are automated machine tools equipped with a program control system. This control system can logically process programs with control codes or other symbolic instructions, decode them, represent them with coded numbers, input them to the CNC device through an information carrier, and after calculation and processing, the CNC device sends out various control signals to control the machine tool's actions, automatically machining parts according to the shape and size required by the drawings. Graphite heat exchangers are devices made of graphite that can perform heat transfer. They have good corrosion resistance and excellent heat transfer performance. In the manufacturing process of graphite heat exchangers, because many holes need to be machined on the graphite heat exchanger blocks to meet the needs of exhaust gas flow, a drilling CNC machine tool is needed to drill holes in the graphite blocks.

[0003] When existing CNC drilling machines drill cylindrical graphite blocks, the drilling depth is relatively long, resulting in the generation of a large amount of graphite debris and carbon ash. The splashing of debris and the scattering of carbon ash cause a thick layer of impurities to cover the machine tool surface, requiring regular manual cleaning. Due to the complexity of the machine tool's internal structure, manual cleaning is tedious and labor-intensive. Furthermore, cleaning debris causes carbon ash to scatter and spread everywhere, greatly impacting the workshop's working environment. Summary of the Invention

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figures 1 to 8 As shown, the present invention provides a drilling CNC machine tool with a chip collection and cleaning function, including a machine tool body 1. The machine tool body 1 is characterized in that: a protective cover 2 is provided on the upper surface of the machine tool body 1, and a chip collection mechanism is provided on the upper surface of the machine tool body 1. The chip collection mechanism includes a first collection box 3, and the chip collection mechanism realizes the collection of chips generated during drilling.

[0035] The machine tool body 1 is equipped with a lifting and positioning mechanism, which includes a positioning rotating rod 4. The lifting and positioning mechanism is located below the chip collection mechanism. The height of the chip collection mechanism can be adjusted by the lifting and positioning mechanism, so as to facilitate drilling and chip collection at different heights.

[0036] The upper surface of the protective cover 2 is provided with a carbon ash collection mechanism, which includes a second collection box 5. The carbon ash collection mechanism is located above the debris collection mechanism. The carbon ash collection mechanism separates the carbon ash from the debris and collects the separated carbon ash.

[0037] The above solution, through the setting of the chip collection mechanism, the lifting and positioning mechanism and the carbon ash collection mechanism, not only can the chips and carbon ash generated in the hole be collected during drilling, but also the chips and carbon ash seeping out of the hole can be collected and treated, thus avoiding the spread of chips and carbon ash to the machine tool body 1, reducing the labor force for manual cleaning and improving the working environment of the workshop.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, two first collection boxes 3 are symmetrically distributed around the axis of the upper surface of the machine tool body 1. A first collection box 31 is movably inserted into the front of the first collection box 3. A mounting box 32 is fixedly connected to the upper surface of the first collection box 3. A hollow drill rod 33 is mounted on one side surface of the mounting box 32 via a bearing. The outer surface of the hollow drill rod 33 has through holes 34 arranged in a ring array. A drill bit 35 is fixedly connected to one end of the hollow drill rod 33. A first gear 36 is fixedly sleeved on the outer surface of the hollow drill rod 33. A first servo motor 37 is fixedly mounted on the inner bottom wall of the mounting box 32. A first rotating shaft is fixedly mounted on the output shaft of the first servo motor 37 via a coupling. A second gear 38 is fixedly sleeved on the outer surface of one end of the first rotating shaft. The tooth surface of the 38 meshes with the tooth surface of the first gear 36. A conical sorting box 39 is mounted on the outer surface of the other end of the hollow drill rod 33 via a sealed bearing. A debris collection pipe 310 is fixedly connected to the outer surface of the conical sorting box 39. One end of the debris collection pipe 310 penetrates and extends to the inner top wall of the first collection box 3. A first drive motor 311 is fixedly mounted on the inner wall of one side of the mounting box 32. A drive rod 312 is fixedly mounted on the output shaft of the first drive motor 311 via a coupling. One end of the drive rod 312 penetrates the conical sorting box 39 and extends into the interior of the hollow drill rod 33. A spiral blade 313 is fixedly sleeved on the outer surface of the drive rod 312. The outer surface of the spiral blade 313 contacts the inner wall of the hollow drill rod 33. A series of actuating plates 314 arranged in a circular array are fixedly connected to the surface of the mounting box 32. One end of the actuating plates 314 contacts the inner wall of the conical sorting box 39. A first mounting cylinder 315 arranged symmetrically is fixedly sleeved on one side of the mounting box 32. A second mounting cylinder 316 is movably sleeved on the inner wall of the first mounting cylinder 315. A first support spring 317 is fixedly connected to one end of the second mounting cylinder 316.

One end of the second support spring 319 is fixedly connected to the inner wall of one side of the second mounting cylinder 316. The two support rods 31... The other end of 8 is fixedly connected to a collection block 320. The inner wall of the collection block 320 is movably sleeved with the outer surface of the hollow drill rod 33. The inner bottom wall of the collection block 320 is provided with symmetrically distributed inclined surfaces 321. The lower surface of the collection block 320 is fixedly connected to a guide pipe 322. One end of the guide pipe 322 is fixedly connected to a first corrugated pipe 323. One end of the first corrugated pipe 323 is fixedly connected to one side surface of the first collection box 3. One side surface of the collection block 320 is fixedly connected to an arc-shaped corrugated rubber block 324. The outer surfaces of both ends of the positioning rotating rod 4 are respectively installed on the inner walls of both sides of the machine tool body 1 through bearings. The outer surface of the positioning rotating rod 4 is fixedly sleeved with a worm gear 41. The inner bottom wall of the machine tool body 1 is fixedly installed with a second drive motor 42.

[0039] The above solution is adopted: the movement of the hollow drill rod 33 causes the collecting block 320 to squeeze the support rod 318. Since the elastic force of the first support spring 317 is greater than that of the second support spring 319, the second support spring 319 and the first support spring 317 cooperate with the second mounting cylinder 316 to retract in sections, thereby cooperating with the movement of the hollow drill rod 33 to drill a hole, so that the arc-shaped corrugated rubber block 324 is tightly attached to the cylindrical graphite block. The collecting block 320 collects the debris and carbon ash seeping out of the hole. One end of the arc-shaped corrugated rubber block 324 is set to be arc-shaped, which can better fit the surface of the cylindrical graphite block and prevent carbon ash and debris from seeping out and falling out when the second drive motor 42 drives the worm gear 43 to rotate clockwise.

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, the output shaft of the second drive motor 42 is fixedly mounted with a worm gear 43 via a coupling. The outer surface of the worm gear 43 meshes with the tooth surface of the worm wheel 41. The outer surface of the positioning rod 4 is fixedly sleeved with a symmetrically distributed first bevel gear 44. The inner walls of both sides of the machine tool body 1 are fixedly connected with symmetrically distributed positioning blocks 45. The inner wall of the positioning block 45 is mounted with a lead screw 46 via bearings. One end of the lead screw 46 passes through and extends to the upper surface of the machine tool body 1. The outer surface of one end of the lead screw 46 is mounted with the inner top wall of the protective cover 2 via bearings. The outer surface of the other end of the lead screw 46 is fixedly sleeved with a second bevel gear 47. The tooth surface of the second bevel gear 47 meshes with the tooth surface of the first bevel gear 44. The outer surface of the lead screw 46 is threadedly connected with a threaded block 48. One side surface of the threaded block 48 is connected to the other side of the mounting box 32. One side surface is fixedly connected to the threaded block 48. The front and back sides of the threaded block 48 are respectively fixedly connected to the symmetrically distributed connecting blocks 49. The inner wall of the connecting block 49 is movably sleeved with a guide rod 410. One end of the guide rod 410 is fixedly connected to the upper surface of the machine tool body 1, and the other end of the guide rod 410 is fixedly connected to the inner top wall of the protective cover 2. A servo electric cylinder 411 is fixedly installed on one side surface of the connecting block 49. One end of the piston rod of the servo electric cylinder 411 is fixedly connected to a drive block 412. The opposing surfaces of the two drive blocks 412 are respectively fixedly connected to the front and back sides of the mounting box 32.

The front of the second collection box 5 is movably inserted with a second collection box 51. The upper surface of the second collection box 5 is fixedly connected with an annular filter box 52.

[0041] The above technical solution is adopted as follows: the second drive motor 42 drives the worm gear 43 to rotate clockwise and counterclockwise. The clockwise rotation of the worm gear 43 drives the positioning rod 4 to rotate through the meshing worm wheel 41. The rotation of the positioning rod 4 drives the meshing second bevel gear 47 to rotate through the first bevel gear 44. The rotation of the second bevel gear 47 drives the lead screw 46 to rotate. The rotation of the lead screw 46 drives the threaded block 48 to move upward through the cooperation of the connecting block 49 and the guide rod 410, thereby driving the mounting box 32 to move upward, realizing the adjustment of the drilling height. This enables the collection of debris and carbon ash in the box when drilling at different heights, improving practicality.

[0042] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8As shown, the annular filter box 52 has exhaust ports 53 arranged in a ring array on its front side. A first connecting pipe 54, symmetrically arranged, is fixedly connected to the back of the annular filter box 52. One end of the first connecting pipe 54 penetrates and extends into the interior of the protective cover 2. A second corrugated pipe 55 is fixedly connected to one end of the first connecting pipe 54. A second connecting pipe 56 is fixedly connected to one end of the second corrugated pipe 55.

One end of the third corrugated pipe 58 is fixedly connected to a fourth connecting pipe 59. One end of the fourth connecting pipe 59 penetrates and extends into the interior of the collection block 320. A symmetrically distributed diversion pipe 510 is fixedly connected to the outer surface of the fourth connecting pipe 59.

An outer toothed ring 515 is fixedly sleeved on one end of the inner fixing ring 514. A dust collection port is opened on the inner wall of the annular filter box 52. One end of the dust collection port is connected to the inner top wall of the second collection box 5. A second servo motor 516 is fixedly installed on the front of the annular filter box 52. A second rotating shaft is fixedly installed on the output shaft of the second servo motor 516 through a coupling. One end of the second rotating shaft passes through the annular filter box 52 and extends to the back of the inner fixing ring 514. The outer surface of the second rotating shaft... A suction blade 517 arranged in a ring array is fixedly connected. The outer surface of the second rotating shaft is mounted to the inner wall of the inner fixing ring 514 via a bearing. A rotating block 518 is fixedly connected to one end of the second rotating shaft. A rotating rod 519 is mounted on the inner wall of the rotating block 518 via a bearing. A third gear 520 is fixedly sleeved on the outer surface of the rotating rod 519. The tooth surface of the third gear 520 meshes with the tooth surface of the outer gear ring 515. A cleaning disc 521 is fixedly connected to one end of the rotating rod 519. The front of the cleaning disc 521 contacts the back of the annular filter screen 513.

[0043] The above technical solution is adopted as follows: the second servo motor 516 drives the suction blades 517 to rotate through the second rotating shaft, which generates airflow and discharges it through the exhaust port 53. The carbon ash is drawn in through the dust collection hopper 511 and transported through the diversion pipe 510 and the fourth connecting pipe 59 to the third corrugated pipe 58. Then, the third corrugated pipe 58 transports it through the third connecting pipe 57 to the second connecting pipe 56. Finally, it is transported through the second corrugated pipe 55 and the first connecting pipe 54 to the annular filter box 52. The cleaning disc 521 rotates during its circular motion, thereby better cleaning the carbon ash on the surface of the annular filter screen 513 and causing it to fall into the second collection box 51.

[0044] Working principle and usage process of this invention:

[0045] Step 1: After the circular graphite block to be drilled is fixed, the second drive motor 42 is started to drive the worm gear 43 to rotate clockwise. The rotation of the worm gear 43 drives the positioning rod 4 to rotate through the meshing worm wheel 41. The rotation of the positioning rod 4 drives the meshing second bevel gear 47 to rotate through the first bevel gear 44. The rotation of the second bevel gear 47 drives the lead screw 46 to rotate. The rotation of the lead screw 46 drives the threaded block 48 to move upward through the cooperation of the connecting block 49 and the guide rod 410, thereby driving the mounting box 32 to move upward to adjust the drilling height. Conversely, when the worm gear 43 rotates counterclockwise, it drives the mounting box 32 to move downward to adjust the height.

[0046] Step two: After adjustment, first start the second servo motor 516. The second servo motor 516 drives the suction blades 517 to rotate via the second rotating shaft, generating airflow, which is then discharged through the exhaust port 53. Next, start the first servo motor 37. The first servo motor 37 drives the second gear 38 to rotate via the first rotating shaft. The rotation of the second gear 38 drives the hollow drill rod 33 to rotate via the meshing first gear 36. The rotation of the hollow drill rod 33 drives the drill bit 35 to rotate. Simultaneously, the servo electric cylinder 411 is activated to extend. The extension of the servo electric cylinder 411 is controlled by the drive block 4. 12 drives the installation box 32 to move. The movement of the installation box 32 causes the arc-shaped corrugated rubber block 324 to press against the cylindrical graphite block and, together with the movement of the hollow drill rod 33, to drill a hole in the cylindrical graphite block. The movement of the hollow drill rod 33 causes the collecting block 320 to press against the support rod 318, causing the second support spring 319 to contract. When the second support spring 319 has contracted, the first support spring 317 will contract in conjunction with the second installation cylinder 316. During drilling, the debris and carbon dust generated in the hole are drawn into the hollow drill rod 33 through the through hole 34 by the adsorption force of the airflow.

[0047] Step three: At this point, the first drive motor 311 is restarted. The first drive motor 311 drives the spiral blade 313 to rotate via the drive rod 312. The rotation of the spiral blade 313 moves the debris and carbon ash into the conical sorting box 39. The drive rod 312 drives the rotation of the agitator plate 314 to tumble and stir the debris and carbon ash. The carbon ash is then conveyed through the second connecting pipe 56 and the second corrugated pipe 55 into the first connecting pipe 54, and finally into the annular filter box 52. The annular filter screen 513 blocks the carbon ash from falling through the dust collection port into the second... Inside the collection box 51, the debris, due to its own weight and the arc surface of the conical sorting box 39, falls through the debris collection pipe 310 into the first collection box 31. At the same time, the rotation of the second rotating shaft drives the cleaning disc 521 to perform a circular motion through the rotating block 518 and the rotating rod 519, thereby cleaning the carbon ash adsorbed on the surface of the annular filter screen 513. Through the cooperation of the external gear ring 515 and the third gear 520, the cleaning disc 521 rotates on its own while performing a circular motion, thereby better cleaning the carbon ash on the surface of the annular filter screen 513 and causing it to fall into the second collection box 51.

[0048] Step four: During drilling, the debris and carbon ash overflowing from the hole will fall into the collection block 320. The carbon ash is sucked in by the dust collection hopper 511 and transported through the diversion pipe 510 and the fourth connecting pipe 59 to the third corrugated pipe 58. Then, the third corrugated pipe 58 is transported through the third connecting pipe 57 to the second connecting pipe 56. Finally, it is transported through the second corrugated pipe 55 and the first connecting pipe 54 to the annular filter box 52. At the same time, the debris inside the collection block 320 slides into the guide inclined pipe 322 due to its own weight and the cooperation of the inclined surface 321. Finally, it is transported to the first collection box 31 through the first corrugated pipe 323.
