Description

Technical Field

[0001] This utility model relates to the technical field of deburring devices, specifically a CNC deburring machine. Background Technology

[0002] In industrial production, removing burrs from product surfaces is a crucial step in improving product quality and aesthetics. Traditionally, dry ice machines have been widely used for deburring, utilizing the impact force and freezing effect of dry ice particles during high-speed spraying to peel burrs from workpiece surfaces. However, with the ever-increasing demands for precision and efficiency in manufacturing, traditional dry ice machine deburring methods are no longer sufficient to meet the needs of modern production in some aspects.

[0003] Existing dry ice deburring machines mostly use fixed or simple motion mechanisms, which cannot adjust the spray angle and path in real time according to the shape of the workpiece. They need to rely on multi-axis fixtures to repeatedly adjust the workpiece posture, resulting in low processing efficiency. Furthermore, dry ice deburring relies on the low-temperature embrittlement effect, which may cause material embrittlement risk to some metals or plastics. In addition, dry ice itself is expensive, and its long-term use is not economical. Utility Model Content

[0004] The purpose of this invention is to provide a CNC deburring machine that deburrs products through a set drive mechanism, guide mechanism and sand-air mixing chamber, thus solving the problem of low processing efficiency of dry ice deburring.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model is a CNC deburring machine, including a machine tool body and a gas pipeline. The machine tool body has a feed opening on the outside and a frame inside the machine tool body. A drive mechanism is installed on the frame. A sand-air mixing chamber is installed at the output end of the drive mechanism. A row of nozzles is installed at the bottom of the sand-air mixing chamber. An air storage tank is installed at the top of the machine tool body. The sand-air mixing chamber and the air storage tank are connected through a gas pipeline. A guide mechanism is installed at the bottom of the machine tool body. A bridge plate is installed on the guide mechanism. The bridge plate is located at the bottom of the nozzles.

[0007] Furthermore, the drive mechanism has an X-axis electric lead screw module and a Z-axis electric lead screw module. The X-axis electric lead screw module is mounted on the top of the frame, and the Z-axis electric lead screw module is set on the output end of the X-axis electric lead screw module. The outer surface of the sand-air mixing chamber is mounted on the output end of the Z-axis electric lead screw module.

[0008] Furthermore, the guiding mechanism has a Y-axis electric lead screw module and a U-shaped plate. The Y-axis electric lead screw module is installed at the bottom of the machine tool body, and a U-shaped plate is installed at the output end of the Y-axis electric lead screw module. Two rotating blocks are connected to the U-shaped plate through a rotating shaft, and the bridge plate is installed in the two rotating blocks.

[0009] Furthermore, a guide rail is installed on the frame, and a slider is installed on the outer surface of the Z-axis electric lead screw module, with the slider slidingly engaged on the guide rail.

[0010] Furthermore, a through hole is provided at the top of the sand-air mixing chamber, and a sand pipe is fitted inside the through hole. A control valve is installed on the nozzle.

[0011] Furthermore, a base is installed at the bottom of the machine tool body, and a filter section is provided inside the base. The filter section has a discharge bin, which is located at the bottom of the bridge plate. A filter screen is installed at the bottom of the discharge bin, and a discharge hole is opened at the bottom of the discharge bin, with a discharge pipe fitted inside the discharge hole.

[0012] This utility model has the following beneficial effects:

[0013] This invention uses a drive mechanism, a guide mechanism, and a sand-air mixing chamber to deburr products. The control software controls the X-axis electric lead screw module, the Z-axis electric lead screw module, and the drive source to work together to position the sand particles on complex curved surfaces and internal holes. This avoids the omissions caused by the fixed path in traditional dry ice machines, avoids the risk of material damage, and ensures the deburring effect of the material.

[0014] This invention uses a discharge hopper and a filter screen to filter impurities. After deburring the product, impurities and sand particles fall into the discharge hopper and are filtered through the filter screen. The sand particles are discharged and collected from the discharge pipe, while the impurities remain on the filter screen for further processing, thus improving the utilization rate of materials and increasing the practicality of the device.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

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.

[0025] Please see Figure 1-7This utility model provides a technical solution: a CNC deburring machine, including a machine body 1 and a gas pipeline 11.

A slider 14 is installed on the outer surface of the Z-axis electric lead screw module 402. The slider 14 is slidably engaged with the guide rail 13. When the sand-air mixing chamber 7 moves laterally through the guide rail 13, the slider... Block 14 slides along guide rail 13 to position the movement of sand-air mixing chamber 7. A drive mechanism 4 is mounted on frame 3, and the sand-air mixing chamber 7 is installed at the output end of drive mechanism 4. A through hole is opened at the top of sand-air mixing chamber 7, and a sand pipe 12 fits inside the through hole. The sand pipe 12 is connected to a sand storage tank.

A guide mechanism 5 is installed at the bottom of the machine tool body 1, and a bridge plate 6 is set on the guide mechanism 5. The bridge plate 6 is located at the bottom of the nozzle 8. When deburring the product, the product is fixed on the outer surface of the bridge plate 6 through the feed opening 101 and the fixation is ensured to be firm. Then, the control software controls the Y-axis electric screw module 501 to move, and controls the X-axis electric screw module 401 and Z-axis electric screw module 402 of the drive mechanism 4 to drive the sand-air mixing chamber 7 to move horizontally and vertically until it moves to the position where the product needs to be deburred. Then, the drive source 504 is started to drive the rotating shaft to rotate, so that the rotating block 503 drives the bridge plate 6 to rotate to adjust the angle of the product. At this time, the control valve 9 is opened so that the sand particles inside the sand-air mixing chamber 7 are mixed with the high-pressure gas and the sand particles are accurately hit by the nozzle 8 onto the part of the product that needs to be deburred, and the product is deburred.

[0026] The drive mechanism 4 has an X-axis electric lead screw module 401 and a Z-axis electric lead screw module 402. The X-axis electric lead screw module 401 is mounted on the top of the frame 3, and the Z-axis electric lead screw module 402 is set on the output end of the X-axis electric lead screw module 401.

The X-axis electric lead screw module 401, Z-axis electric lead screw module 402, Y-axis electric lead screw module 501 and drive source 504 are all electrically connected to the control software. The control software adopts a closed loop of CNC control system and drive to achieve high-speed and precise control. It is compatible with design software such as MasterCAM, ArtCAM, Pro-E, UG, and AutoCAD. Three permission modes (operator mode, manufacturer mode, and developer mode) can protect the machine tool parameters at various levels and avoid operator misoperation. The X-axis electric lead screw module 401, Z-axis electric lead screw module 402, Y-axis electric lead screw module 501 and drive source 504 can move the sand-air mixing chamber 7 and bridge plate 6 to a designated position.

[0027] A base 2 is installed at the bottom of the machine tool body 1. A filter section is provided inside the base 2. The filter section has a discharge chamber 201.
