Technical Field

[0001] The utility model relates to the technical field of deburring, and particularly relates to a laser burr polishing machine. Background Art

[0002] The application of lasers is becoming more and more extensive. Usually, laser printing is carried out on workpieces. For the workpieces printed by lasers, burrs will remain on their processed surfaces and need to be polished. For existing polishing devices, such as a burr trimming mechanism and a polishing device disclosed in the application number 2021109125943, the polishing device includes a polishing disc, a mounting body, and a rotating mechanism. The mounting body can hold the workpiece to be polished, and the mounting body is arranged opposite to the polishing disc; the rotating mechanism includes a rotating shaft connected to the mounting body. The rotating shaft is perpendicular to the mounting body, and the rotating shaft can drive the mounting body to rotate on the polishing disc to polish the workpiece to be polished. When in use, the polishing workpiece is placed on the mounting body and the surface to be polished of the polishing workpiece faces the polishing disc, and the rotating mechanism is driven to drive the mounting body to rotate, so that a smooth surface is formed on the surface of the polishing workpiece facing the polishing disc.

[0003] However, if the surface to be polished of the polishing workpiece has an arc surface, when the above polishing device is polishing, the polishing disc cannot be adjusted to fit the arc surface, so that the burrs inside the arc surface cannot be polished. The existing polishing workpieces with arc surfaces still stay in the stage of manual polishing, with poor polishing effect and low processing efficiency.

[0004] In view of this, the inventor of this case has conducted in-depth research on the problem, and thus this case has been generated. Summary of the Utility Model

An embedding through groove for embedding the workpiece to be polished and leading to the outside of the bottom surface of the bottom plate is opened on the bottom plate. This embedding through groove is the accommodating groove. The cushion plate is stacked above the bottom plate and is embedded within the range of the accommodating shell.

If the polishing surface of the workpiece to be polished is an arc surface, under the downward pressure of the pressing plate and the backing plate on the top surface of the workpiece to be polished, the soft deformation layer below the workpiece to be polished deforms, and the polishing layer also deforms accordingly, so that the polishing layer enters the range of the arc surface of the workpiece to be polished.

Compared with the prior art, the polishing of the workpiece to be polished is not limited to the polishing of flat workpieces. It uses the deformation effect of the soft deformation layer to enable the polishing layer to contact the arc-shaped polishing surface, so that the workpiece to be polished with an arc structure can also be polished, and the applicable range is relatively wide.

[0018] Figure 1 is a schematic structural diagram of one embodiment of the present utility model.

[0019] Figure 2 is another schematic structural diagram of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to further explain the technical solution of the present utility model, the following will be elaborated in detail with reference to the accompanying drawings.

[0021] A laser burr polishing machine, as Figure 1 - Figure 2As shown in the figure, it includes a frame, a polishing disc 1 mounted on the frame, and a mounting body 2 for mounting a polishing piece. The polishing disc 1 and the mounting body 2 are rotationally matched with each other. The polishing disc 1 is rotatably mounted on the frame. The polishing disc 1 has a mounting layer 11, a soft deformation layer 12, and a polishing layer 13 stacked and connected together from bottom to top. Specifically, the frame has a mounting seat 3. The mounting seat 3 is of a hollow structure. The top surface of the mounting seat 3 is provided with a working disc 31 which is of a hollow structure and has an open top surface. The top surface of the mounting seat 3 is provided with a water flushing device 32 outside the working disc 31. The output end of the water flushing device 32 faces the center of the working disc 31. The way the water flushing device flushes water is a well-known technology and will not be elaborated here. The bottom surface of the working disc 31 protrudes downward to form a water outlet column (not shown in the figure) extending into the mounting seat 3. The water outlet column is provided with a water outlet channel communicating the hollow chamber of the mounting seat 3 and the hollow chamber of the working disc 31. A collection box (not shown in the figure) is provided in the mounting seat 1 below the water outlet column. The center part of the inner bottom surface of the working disc 31 protrudes upward to form a fixed disc 311. The top surface of the fixed disc 311 is lower than the top surface of the working disc. The polishing disc 1 is stacked on the top surface of the fixed disc 311, and the top surface of the polishing disc 1 is also lower than the top surface of the working disc 311. The mounting layer 11 is in contact with the top surface of the fixed disc 311. The mounting seat 3 is provided with a rotating shaft 33 that penetrates upward through the fixed disc 311. The upper end of the rotating shaft 33 is connected to the mounting layer 11. A water drainage gap is formed between the outer side wall of the polishing disc 1 and the inner side wall of the working disc 31. During application, the water flushing device is started. The water outlet end of the water flushing device flushes the polishing disc, so that the burrs on the polishing disc flow down along with the water from the outer side wall of the polishing disc, flow through the water outlet column and reach the collection box. At the same time, the rotating shaft can drive the polishing disc to rotate. During the rotation of the polishing disc, the water will be thrown out, and the inner side wall of the working disc 311 will throw the water back and fall within the range of the water drainage gap, and finally flow out from the water outlet column.

[0022] The mounting body 2 includes a receiving plate 21, a cushion plate 22 and a pressing plate 23. The receiving plate 21 is placed flat above the polishing layer 13. The receiving plate 21 has a receiving groove for the workpiece to be polished to be received therein and to contact the polishing layer 13. The cushion plate 22 is a soft cushion plate and is placed flat in the receiving plate 21. The pressing plate 23 is a gravity plate and is stacked on the cushion plate 22. Specifically, the mounting layer 11 is a metal plate body, such as an iron plate or a steel plate. The upper end of the rotating shaft 33 is locked to the metal plate body, that is, an installation piece (not shown in the figure) is locked to the upper end of the rotating shaft 33, and the installation piece is locked to the mounting layer 11. The soft deformation layer 12 is a rubber plate or a silica gel plate and is adhered to the metal plate body. The polishing layer 13 is a sandpaper board and is adhered to the top surface of the soft deformation layer 12. The receiving plate 21 has a receiving shell 211 and a bottom plate 212. The receiving shell 211 is a hollow cylindrical structure with both ends open. The bottom plate 212 is embedded in the receiving shell 211 and is in close fit with the polishing layer 13. The bottom plate 212 is provided with an embedding through groove for the workpiece to be polished to be embedded therein and to lead to the outside of the bottom surface of the bottom plate 212. This embedding through groove is the receiving groove. The cushion plate 22 is stacked above the bottom plate 212 and is embedded in the receiving shell. The cushion plate 22 is a rubber plate or a silica gel plate. The pressing plate 23 is a metal plate stacked above the cushion plate 22, such as an iron plate or a steel plate, and the pressing plate is embedded in the receiving shell. Preferably, a handle 231 for facilitating the removal of the pressing plate is provided on the top surface of the pressing plate 23. During application, the workpiece to be polished with an arc surface is embedded in the embedding through groove, and the side with the arc surface is set towards the polishing disc. The soft cushion plate is stacked on the workpiece to be polished. At the same time, under the action of the gravity of the pressing plate, the workpiece to be polished is pressed down. As the workpiece to be polished is pressed down, under the action of the soft deformation layer 12, the sandpaper board will deform accordingly and enter into the arc surface of the workpiece to be polished. By driving the rotation of the rotating shaft 33, the polishing disc rotates, and the sandpaper board can also continuously deform under the action of the soft deformation layer and continuously contact the arc surface of the workpiece to be polished, so that the arc surface of the workpiece to be polished is continuously polished on the sandpaper board. There is a soft deformation layer below the workpiece to be polished and a soft cushion plate above the workpiece to be polished, so that the workpiece to be polished can be evenly stressed up and down during the polishing process, and the polishing effect of the workpiece to be polished is better. Moreover, the bottom plate 212 is embedded in the receiving shell 211, and the bottom plate 212 can be replaced to replace different receiving grooves, so as to adapt to different workpieces to be polished for polishing.

[0023] A rotary drive device for driving the polishing disc 1 and the mounting body 2 to rotate simultaneously at different speeds is installed on the frame. The rotary drive device has a power rotary drive device and a mechanical rotary drive device. The power drive device is drivingly connected to the mounting layer 11, that is, the lower end of the rotating shaft 33 is drivingly connected to the power drive device. A driven wheel 331 is sleeved outside the lower end of the rotating shaft 33. The power drive device has a rotating motor 4, and a driving wheel (not shown in the figure) is sleeved on the output end of the rotating motor 4. The driving wheel and the driven wheel 331 are rotationally connected by a transmission belt. During application, the rotating motor 4 is driven, and the driving wheel, the driven wheel 331 and the transmission belt rotate, driving the rotating shaft to rotate, and thus driving the polishing disc to rotate.

[0024] The mechanical rotation driving device has a holding device for holding the accommodating disk 21 to rotate at the same position and a speed reducing device 5 for controlling the rotation speed of the accommodating disk 21 to be lower than that of the polishing disk 1; specifically, the holding device has a first clamping structure 6, and the first clamping structure 6 has a first adjusting rod 61 and a first clamping rod 62. A first fixed seat 34 is provided outside the working disk 31 on the top surface of the mounting seat 3. The first adjusting rod 61 is a bar-shaped rod structure. The first end of the first adjusting rod 61 is mounted on the first fixed seat 34 in a manner that can be horizontally adjusted and fixed on the first fixed seat 34, that is, the first adjusting rod is provided with a strip-shaped hole that penetrates up and down and extends along the length direction of the first adjusting rod. A fixing hole is provided at the position corresponding to the strip-shaped hole on the top surface 31 of the first fixed seat. The first adjusting rod 61 is connected to the first fixed seat 34 through an adjusting bolt sequentially passing through the strip-shaped hole and the fixing hole. The second end of the first adjusting rod 61 is stacked on the top surface of the working disk 31 and extends into the hollow chamber of the working disk 31 and is arranged towards the accommodating shell 211. The first clamping rod 62 has a first connecting portion 621 and a first arc portion 622. The first connecting portion 621 is a rod structure. The end of the second end of the first adjusting rod 61 is hinged to the end of the first end of the first connecting portion 621, that is, the end of the second end of the first adjusting rod 61 and the end of the first end of the first connecting portion 621 are both provided with hinge holes, and the two hinge holes are connected by a hinge shaft. The first arc portion 622 is located at one end of the first connecting portion 621 facing the accommodating shell 211. The first arc portion 622 is an arc-shaped plate body that matches the radian of the outer side wall of the accommodating shell 211. The accommodating shell 211 is clamped within the range of the first arc portion 622, that is, the arc length of the first arc portion 622 is greater than the semi-circular arc length of the accommodating shell, so that the accommodating shell 211 is clamped within the first arc portion. The speed reducing device 5 is installed at both ends of the arc-shaped plate body; during application, the first adjusting rod 61 is fixed at the required position through the strip-shaped hole, the fixing hole and the adjusting bolt. When the accommodating shell 211 is driven by the polishing disk to rotate, since the first adjusting rod 61 and the first clamping rod 62 are hinged together by a hinge shaft, the accommodating shell 211 can also adaptively swing in the horizontal direction accordingly. At the same time, the accommodating shell 211 is clamped within the range of the first arc portion 622, so that during the rotation of the polishing disk, the accommodating shell 211 can also be limited to a certain extent, and a certain limit is also imposed on the large-amplitude shaking of the accommodating shell, so that the workpiece to be polished can be polished within the range of the polishing disk.

[0025] The speed reduction device 5 has speed reduction wheels. The speed reduction wheels are vertically arranged and are in close fit with the outer side wall of the accommodation shell 211. There are two speed reduction wheels, and the two speed reduction wheels are respectively installed at the two end parts of the first arc part 622. That is, the speed reduction wheels are provided with rotating shafts extending out of the top surface of the speed reduction wheels. At the two end parts of the bottom surface of the first arc part 622, insertion grooves for the rotation to extend in are concavely provided. The bottom of the insertion groove is concavely provided with locking holes upwards. The top surface of the rotating shaft is concavely provided with locking holes corresponding to the positions of the locking holes. The locking screws sequentially pass through the locking holes and the locking holes and are locked with the rotating shaft together. During application, when the polishing disc rotates, the accommodation shell 211 is correspondingly driven to rotate on the polishing layer of the polishing disc, thereby driving the workpiece to be polished to be polished on the polishing layer. At this time, the accommodation shell 211 is clamped between the two speed reduction wheels. On the one hand, the accommodation shell 211 is limited in position, and on the other hand, the movement speed of the accommodation shell 211 relative to the polishing disc can be reduced, so that the rotation speed of the accommodation shell is less than the rotation speed of the polishing wheel, and the workpiece to be polished can be finely polished.

[0026] For a laser burr polishing machine of the present utility model, during application, the workpiece to be polished is embedded in the accommodation groove, and the polishing surface of the workpiece to be polished is arranged downward. Then, the backing plate 22 and the pressing plate 23 are sequentially pressed into the accommodation shell. If the polishing surface of the workpiece to be polished is an arc surface, under the downward pressure of the pressing plate 23 and the backing plate 22 on the top surface of the workpiece to be polished, the soft deformation layer 12 below the workpiece to be polished deforms, and the polishing layer 13 also deforms accordingly, so that the polishing layer enters the range of the arc surface of the workpiece to be polished. Then, the polishing disc is driven to rotate, and the polishing disc drives the installation body to rotate. During the rotation process, the polishing layer 13 continuously deforms and contacts the arc surface for polishing. Moreover, during the movement of the installation body, the device clamps and limits the installation body, and the speed reduction device makes the rotation speed of the installation body less than the rotation speed of the polishing disc, thereby increasing the polishing effect of the workpiece to be polished. Compared with the prior art, the polishing of the polishing workpiece is not limited to polishing flat polishing workpieces. It uses the deformation effect of the soft deformation layer to enable the polishing layer to contact the arc-shaped polishing surface, so that the polishing workpiece with an arc structure can also be polished, and the applicable range is relatively wide.

[0027] In this new type, preferably, the holding device further has a second clamping structure 7. The second clamping structure 7 has a second adjusting rod 71 and a second clamping rod 72. A second fixing seat 35 is provided outside the working disk 31 on the top surface of the mounting seat 3. The first fixing seat 34 and the second fixing seat 35 are respectively outside both sides of the working disk 31. The first end of the second adjusting rod 71 is mounted on the second fixing seat 35 in a manner that can be horizontally adjusted and fixed on the top surface of the second fixing seat 35. The adjusting structure of the second adjusting rod 71 on the second fixing seat 35 is similar to the adjusting structure of the first adjusting rod 61 on the first fixing seat 34, which will not be elaborated here. The second end of the second adjusting rod 71 is stacked on the top surface of the working disk 31 and extends into the hollow chamber of the working disk 31 and is set towards the accommodating shell 211. The second clamping rod 72 has a second connecting portion 721 and a second arc portion 722. The second connecting portion 721 is in a rod structure, and a horn structure that gradually tapers from the inside to the outside is formed between the second connecting portion 721 and the first connecting portion 621. The end of the second end of the second adjusting rod 71 and the first end of the second connecting portion 721 are hinged together through a hinge shaft. The hinging manner of the second adjusting rod 71 and the second connecting portion 721 is similar to the hinging manner of the end of the second end of the first adjusting rod 61 and the first end of the first connecting portion 621, which will not be elaborated here. The second arc portion 722 is at the second end of the second connecting portion 721, and the second arc portion 722 is an arc-shaped plate body that matches the radian of the outer side wall of the accommodating shell 211. The second arc portion 722 is in close fit with the accommodating shell 211, that is, the second arc portion forms a strip-shaped block structure. An arc-shaped groove that matches the outer shape of the accommodating shell is recessed on the inner end face of the second arc portion. An anti-slip pad is locked on the bottom of the arc-shaped groove. A triangular space is formed between the bottom of the arc-shaped groove and the two speed reduction wheels. At this time, whether the arc length of the first arc portion 622 is greater than or less than the semi-arc length of the accommodating shell, the accommodating shell can be clamped; during application, the accommodating shell is clamped by the relative cooperation of the second clamping structure and the first clamping structure. While the accommodating shell is driven to rotate by the polishing disk, it is also limited to a certain extent, and the accommodating shell will not fly out, so that the accommodating shell can drive the workpiece to be polished within the range of the polishing disk for polishing; at the same time, the two speed reduction wheels and the second arc portion clamp the accommodating shell in a triangular shape, so as to more stably clamp and limit the accommodating shell.

[0028] The product form of the present utility model is not limited to the illustrations and embodiments of this case. Any person's appropriate changes or modifications with a similar idea should be regarded as not departing from the patent scope of the present utility model.
