Technical Field

[0001] The utility model relates to a novel digitally controlled precision panel saw, belonging to the technical field of precision panel saws. Background Art

[0002] Precision panel saws are also called sliding table saws. They are mainly used for longitudinal, transverse or angled sawing of plywood, particleboard, fiberboard, veneer, laminated board, blockboard, spliced ​​solid wood board and plastic board to obtain panels that meet the specifications. They can also be used for sawing various insulation boards, thin aluminum plates and aluminum profiles.

[0003] When the current precision panel saw is used, the worker places the workpiece on the precision panel saw, and then turns on the control device of the equipment to cut the workpiece. When the cutting is completed, the worker collects the waste generated during the cutting, and then completes the work;

[0004] When in use, traditional precision panel saws cannot automatically collect the dust generated during cutting, and because of the precision cutting, the debris generated is mostly small, which makes it easy for the debris to spread into the surrounding air. When workers inhale the debris for a long time, it will cause damage to the human body, thus bringing inconvenience to the workers. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide a novel CNC precision panel cutting saw, which can automatically collect fine debris generated during cutting, thereby not only improving product processing quality but also ensuring the health of workers.

[0007] A detection camera is installed on one side of the cutter, and scale plates are installed on both sides of the top of the processing platform.

The new type of CNC precision panel saw also comprises: a dust removal device 2, which is arranged above the cross rail 7; a fixing device 3, which is installed on the top of the bottom plate 1; and a driving device 4, which is arranged below the processing platform 6; wherein the dust removal device 2 can collect fine waste chips generated during processing, the fixing device 3 can fix and limit the workpiece to be processed, and the driving device 4 can change the position of the processing platform 6;

[0021] In the specific implementation process, it is worth pointing out that the cutter 9 can cut the workpiece. Its main structure is a driving device plus a cutting blade. This is an existing known technology. The present case has not made any structural improvements and innovations, so it will not be described in detail. The technicians in this field should have a broad understanding. The power slider 8 is a driving device on the existing CNC machine tool. This is an existing known technology. Therefore, it will not be described in detail. The technicians in this field should have a broad understanding. The power slider 8 in this case can drive the cutter 9 and other components to move along the outer wall of the cross rail 7;

[0022] Further, such as Figure 4 As shown, a detection camera 5 is installed on one side of the cutter 9, and scale plates 10 are installed on both sides of the top of the processing platform 6; the model of the detection camera 5 is not specifically limited, and it can meet the use requirements. The cooperation of the detection camera 5 and the scale plate 10 can detect the position of the workpiece above the processing platform 6;

[0023] Specifically, when using the new CNC precision panel saw, the staff first places the workpiece on the top of the processing platform 6, and then the staff turns on the external power supply of the detection camera 5. At this time, the detection camera 5 can detect the position of the workpiece, and then transmits the detection signal to the external control device of the new CNC precision panel saw, and then the external control device can turn on the external power supply of the power slider 8. At this time, the power slider 8 can drive the cutter 9 and other components to move along the outer wall of the cross rail 7. When the cutter 9 reaches the appropriate position, the staff turns on the external power supply of the drive device 4. At this time, the drive device 4 can drive the processing platform 6 to move. When the workpiece moves to a certain position, it can be fixed by the fixing device 3. Then the staff turns on the external power supply of the cutter 9. At this time, the cutter 9 can cut the workpiece. At the same time, the staff turns on the external power supply of the dust removal device 2. At this time, the dust removal device 2 can collect the waste chips generated during cutting.

[0024] The dust removal device 2 includes: a collection box 201, which is installed on the top of the power slider 8; a fan 202, the model of which is YNF-200-2T, which can be detachably connected to the inside of the collection box 201; a filter 203, the mesh number of which is not limited, and it can be installed inside the collection box 201 as long as it meets the use requirements; a duct 204, which is arranged on one side of the bottom of the collection box 201 and extends to the bottom of the cutter 9; a hollow plate 205, which is installed below the cutter 9 and is connected to the end of the duct 204; a shielding brush 206, which is installed at the bottom of the hollow plate 205; wherein the fan 202 can extract the air inside the collection box 201, and then use the duct 204 to suck the waste generated during processing into the collection box 201 through the negative pressure effect;

[0025] In the specific implementation process, it is worth pointing out that the shielding brush 206 can block the flying waste so that it can better pass through the hollow plate 205 and the conduit 204 into the interior of the collection box 201, and the filter 203 can filter the air entering the interior of the collection box 201, and can block the waste in the air inside the collection box 201, thereby realizing the collection of waste;

[0026] Specifically, when collecting waste chips, the staff turns on the external power supply of the fan 202, and then the fan 202 can extract the air inside the collection box 201, thereby reducing the air pressure inside the collection box 201. At this time, the debris can enter the hollow plate 205 through the airflow, and then be transported through the duct 204, and finally enter the collection box 201. When the air enters the collection box 201, it is filtered and blocked by the filter net 203, and then the collection work can be completed.

[0028] When the processing platform 6 drives the workpiece to move to a certain position, the second vertical plate 303 can be driven to move along the inside of the first vertical plate 301 by the horizontal roller 304, thereby stretching the spring 302, and then the horizontal roller 304 can limit the workpiece through the elastic force of the spring 302;

[0029] When the driving device 4 drives the processing platform 6 to move, when the processing platform 6 drives the workpiece to move to a certain position, the cross roller 304 is subjected to force, and the second vertical plate 303 can be driven to move along the inside of the first vertical plate 301, and the spring 302 begins to be stretched. At this time, due to the elastic force of the spring 302, the second vertical plate 303 can be given a downward force, so that the cross roller 304 can tighten the workpiece and limit it. When the workpiece continues to move, the cross roller 304 can rotate along the top of the second vertical plate 303, so that the workpiece can continue to move to complete the processing.

[0030] The driving device 4 includes: a servo motor 401, the model of the servo motor 401 is ECMA-E11320RS, two of which are provided and can be detachably connected to one side of the base plate 1; two lead screws 402 are provided, which are detachably connected to the output ends of the two servo motors 401, and are rotatably connected to the inner wall of the base plate 1 through bearings; a plurality of screw nuts 403 are provided, which are respectively threadedly connected to the outer walls of the two lead screws 402, and are slidably engaged with the inner wall of the base plate 1; a plurality of sliders 404 are provided, which are respectively installed on the tops of a plurality of screw nuts 403, and are connected to the bottom of the processing platform 6; two slide rails 405 are provided, which are both installed on the top of the base plate 1 and are slidably engaged with the inner walls of a plurality of sliders 404; wherein the servo motor 401 can drive the screw nut 403 through the lead screw 402 to drive the slider 404 to slide along the outer wall of the slide rail 405;
