Description

Technical Field

[0001] This utility model relates to the field of casting technology, and more specifically, to a machine tool for processing castings. Background Technology

[0002] Castings are metal shaped objects obtained through various casting methods. Specifically, castings are made by injecting smelted liquid metal into a pre-prepared mold through methods such as pouring, injection, or suction. After cooling, the castings undergo subsequent processing such as grinding to finally obtain objects with a certain shape, size, and performance. However, the surface of castings has burrs and requires further processing.

[0003] The existing method of processing castings involves placing the cooled castings on top of a machine tool and then using drilling and grinding tools to perform precision machining on the cast parts, ensuring that the parts meet the required machining dimensions and standards.

[0004] However, when castings are being ground and drilled, metal dust is generated. Since masks have limited filtration capabilities, long-term production and processing can lead to excessive metal dust levels in the factory, requiring unified ventilation treatment, which in turn increases the production cost of castings. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model proposes a machine tool for processing castings.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a machine tool for processing castings, comprising a sliding block, a drive shaft rotatably connected to the output end of the sliding block, a processing cutter head fitted at the end of the drive shaft away from the sliding block, a transmission belt rotatably connected to the outside of the drive shaft, a driven shaft rotatably connected to the inner side of the transmission belt away from the drive shaft, the driven shaft rotatably connected to the side of the sliding block near the drive shaft, a rotating rod fixedly connected to the end of the driven shaft away from the drive shaft, fan blades fixedly connected to the outside of the rotating rod away from the driven shaft, multiple sets of fan blades arranged in a circumferential array, a suction sleeve provided outside the fan blades, a connecting plate fixedly connected to the end of the suction sleeve near the rotating rod, and the connecting plate fixedly connected to one side of the sliding block near the driven shaft.

[0007] Furthermore, the suction sleeve has a dust collection chamber inside, and a dust collection box is provided inside the dust collection chamber. A filter hole is provided on the inner side of the dust collection box near the fan blade. A sliding sleeve is slidably connected to the outside of the suction sleeve near the dust collection box. The side of the sliding sleeve away from the driven shaft abuts against a limit block. The limit block is fixedly connected to the outside of the suction sleeve.

[0008] Furthermore, the bottom of the dust collection box is provided with suction holes, and there are multiple sets of suction holes arranged in a circumferential array at the bottom of the dust collection box. A sealing plate is slidably connected inside the dust collection box near the suction holes, and a reset component is provided on the side of the sealing plate away from the suction holes.

[0009] Furthermore, the reset assembly includes a spring, which is fixedly connected to the side of the sealing plate away from the suction hole, and the end of the spring away from the sealing plate is fixedly connected to the side of the dust collection box near the filter hole. A telescopic rod is provided inside the spring, and the telescopic rod is fixedly connected to the side of the dust collection box opposite to the sealing plate.

[0010] Furthermore, a dust suction head is fixedly connected to the end of the suction sleeve away from the rotating rod. The dust suction head is arc-shaped, and the end of the dust suction head away from the suction sleeve is located on the outside of the processing head near the bottom.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-7 As shown, a machine tool for processing castings includes a sliding block 1. A drive shaft 2 is rotatably connected to the output end of the sliding block 1. A processing head 17 is fitted into the end of the drive shaft 2 away from the sliding block 1. A transmission belt 3 is rotatably connected to the outside of the drive shaft 2. A driven shaft 4 is rotatably connected to the inside of the transmission belt 3 away from the drive shaft 2. The driven shaft 4 is rotatably connected to the side of the sliding block 1 near the drive shaft 2. A rotating rod 5 is fixedly connected to the end of the driven shaft 4 away from the drive shaft 2. A fan blade 6 is fixedly connected to the outside of the rotating rod 5 away from the driven shaft 4. Multiple sets of fan blades 6 are arranged in a circumferential array. A suction sleeve 7 is provided outside the fan blades 6. A connecting plate 8 is fixedly connected to the end of the suction sleeve 7 near the rotating rod 5. The connecting plate 8 is fixedly connected to one side of the sliding block 1 near the driven shaft 4.

[0025] When the casting is being processed, the drive shaft 2 can be driven to rotate by the sliding block 1, which in turn drives the processing cutter head 17 to rotate, thus processing the casting. When the drive shaft 2 rotates, it drives the transmission belt 3 to drive the driven shaft 4, the rotating rod 5, and the fan blade 6 to rotate, thereby allowing metal dust or particles to be sucked into the suction sleeve 7. The suction sleeve 7 is fixed by the connecting plate 8, which ensures the stability of the suction sleeve 7 during suction. This structure achieves the effect of processing and suction at the same time, increases the effect of a single drive source driving multiple sets of structures, and improves the cleaning effect of metal dust.

[0026] like Figures 2-4As shown, a dust collection chamber 9 is provided inside the suction sleeve 7, and a dust collection box 10 is provided inside the dust collection chamber 9. A filter hole 11 is provided on the inner side of the dust collection box 10 near the fan blade 6. A sliding sleeve 21 is slidably connected to the outside of the suction sleeve 7 near the dust collection box 10. The side of the sliding sleeve 21 away from the driven shaft 4 abuts against a limit block 22. The limit block 22 is fixedly connected to the outside of the suction sleeve 7.

[0027] When using the rotating rod 5 and fan blade 6 to perform vacuuming, the airflow will suck the metal dust into the vacuum chamber 10 inside the vacuum chamber 9 along the filter hole 11. When the vacuum chamber 10 stores enough metal dust, the sliding sleeve 21 can be slid outside the suction sleeve 7, so that the vacuum chamber 9 can be opened and a new vacuum chamber 10 can be replaced. When the vacuum chamber 9 is closed by closing the sliding sleeve 21, the limiting block 22 can support the sliding sleeve 21, ensuring the absorption, storage and replacement effect of the vacuum chamber 10.

[0028] like Figures 2-5 As shown, the bottom of the dust collection box 10 is provided with a suction hole 15. There are multiple sets of suction holes 15 arranged in a circumferential array at the bottom of the dust collection box 10. A sealing plate 14 is slidably connected inside the dust collection box 10 near the suction hole 15. A reset component is provided on the side of the sealing plate 14 away from the suction hole 15.

[0029] During adsorption, the suction sleeve 7 generates suction, which allows metal dust to be drawn into the dust collection box 10 along the suction hole 15. When the fan blade 6 is not rotating, the sealing plate 14 will fall, allowing the metal dust to be stored inside the dust collection box 10. This ensures the dust storage effect of the dust collection box 10 and improves the dust storage effect of the dust collection box 10 on metal dust.

[0030] like Figures 2-5 As shown, the reset assembly includes a spring 13, which is fixedly connected to the side of the sealing plate 14 away from the suction port 15. The end of the spring 13 away from the sealing plate 14 is fixedly connected to the side of the dust collection box 10 near the filter port 11. A telescopic rod 12 is provided inside the spring 13, which is fixedly connected to the side of the dust collection box 10 opposite to the sealing plate 14.

[0031] When adsorbing metal dust, the suction force of the fan blade 6 can cause the suction head 16 to squeeze the spring 13, which in turn causes the spring 13 to tighten the telescopic rod 12, thereby collecting the metal dust. When the fan blade 6 stops rotating, the telescopic rod 12 and the spring 13 will push the sealing plate 14, thereby closing the suction hole 15 and preventing the metal dust from flowing out of the suction hole 15.

[0032] like Figures 1-7As shown, a suction head 16 is fixedly connected to the end of the suction sleeve 7 away from the rotating rod 5. The suction head 16 is arc-shaped. The end of the suction head 16 away from the suction sleeve 7 is located on the outside of the processing head 17 near the bottom. A sliding support beam 18 is slidably connected to one side of the sliding block 1. A control panel 19 is slidably connected to both ends of the sliding support beam 18. A positioning table 20 is fixedly connected to the control panel 19 near the sliding block 1.

[0033] The sliding support beam 18 can support the sliding block 1, allowing the sliding block 1 to move laterally and longitudinally, thereby processing the parts on the top of the positioning table 20. When moving back and forth, the sliding support beam 18 can slide on the top of the control table 19, thus ensuring the stability and precision of the casting processing. The structure of the dust suction head 16 can also allow the processing head 17 to process while simultaneously adsorbing the metal dust at the processing position of the processing head 17.

[0034] Working principle: When the casting is being processed, the sliding block 1 drives the drive shaft 2 to rotate, which in turn drives the processing cutter head 17 to rotate, thus processing the casting. The rotation of the drive shaft 2 drives the transmission belt 3, which in turn drives the driven shaft 4, rotating rod 5, and fan blade 6 to rotate, thereby drawing metal dust or particles into the suction sleeve 7. The suction sleeve 7 is fixed by the connecting plate 8, ensuring its stability during suction. This structure achieves the effect of simultaneous processing and suction, increasing the efficiency of a single drive source driving multiple structures. The driving effect improves the cleaning effect of metal dust. When using the rotating rod 5 and fan blade 6 to rotate for vacuuming, the airflow will suck the metal dust into the vacuum chamber 10 inside the vacuum box 9 along the filter holes 11. When the vacuum box 10 stores enough metal dust, the sliding sleeve 21 can be slid outside the suction sleeve 7, thus opening the vacuum chamber 9 and replacing the vacuum box 10. When closing the vacuum chamber 9, the sliding sleeve 21 can be supported by the limiting block 22, ensuring the absorption, storage, and replacement effect of the vacuum box 10. During suction, the suction... The sleeve 7 generates suction, allowing metal dust to be drawn into the dust collection box 10 through the suction port 15. When the fan blade 6 is not rotating, the sealing plate 14 falls, allowing the metal dust to be stored inside the dust collection box 10. This ensures the effective storage of dust in the dust collection box 10 and improves its ability to collect metal dust. When adsorbing metal dust, the suction force of the fan blade 6 causes the suction head 16 to compress the spring 13, which in turn causes the telescopic rod 12 to tighten, thereby collecting the metal dust. When the fan blade 6 stops rotating, the telescopic rod 12 and the spring 13... The sealing plate 14 will be pushed to close the suction hole 15, preventing metal dust from flowing out of the suction hole 15. The sliding block 1 can be supported by the sliding support beam 18, allowing the sliding block 1 to move laterally and longitudinally, thereby processing the parts on the top of the positioning table 20. When moving back and forth, the sliding support beam 18 can slide on the top of the control table 19, thus ensuring the stability and accuracy of the casting processing. The structure of the dust suction head 16 can also allow the processing head 17 to process while simultaneously adsorbing the metal dust at the processing position of the processing head 17.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
