[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains; the terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more of the associated listed items.

[0019] Refer to the attached Figure 1-10 The present invention provides a workpiece chamfering, deburring and dust harmless collection device, comprising a feeding conveyor line 1, a discharging conveyor line 2, a robotic arm 3 and a grinding assembly 31 arranged at the final execution end thereof, and also includes the following structure: The frame 4 has a rotating cylinder 7 fixed on both sides of the front end. A truss 71 is fixed on the front end of the rotating cylinder 7. A blow pipe 72 is detachably connected to the top of the truss 71. A plurality of air holes 73 are formed on the surface of the blow pipe 72. The opening angle of the air holes 73 ranges from -40° to +15°. The first-level fence 8 has a second-level fence 81 movably connected to the middle of the first-level fence 8 , and the third-level fence 82 is movably connected to the middle of the second-level fence 81 .

[0020] In this embodiment, a plurality of electromagnetic valves 41 are fixedly provided on both sides of the front end of the frame 4. The electromagnetic valves 41 cooperate with the rotary cylinder 7. The air outlet side of the electromagnetic valve 41 is fixedly connected to the air inlet of the blowing pipe 72 through a pipeline.

[0021] The electromagnetic valve 41 is arranged at the bottom of the frame 4 to facilitate the rotary cylinder 7 and the blowing pipe 72 to obtain the air source.

[0022] In this embodiment, a top frame 5 is fixed to the rear end of the frame 4, and an electric rotary module 51 is fixed to the rear side of the top frame 5. The front execution end of the electric rotary module 51 is fixedly connected to the rear end of the docking shaft 52. A connecting plate 53 is fixed to the middle of the docking shaft 52. The top and left and right sides of the middle of the connecting plate 53 are movably connected with guide wheels 54. The opposite sides of the guide wheels 54 at the top and middle of the connecting plate 53 are respectively slidably connected to the outer sides of the guide slide rails 55, and the rear side of the guide slide rails 55 are fixedly connected to the front side of the top frame 5.

[0023] The electric rotary module 51 cooperates with the docking shaft 52 to drive the mounting frame 6 to flip over the frame 4, flipping the deburring surface of the workpiece on the mounting frame 6 toward the middle of the primary fence 8, and dumping the metal debris and dust remaining in the grooves on the workpiece surface into the primary fence 8, so as to prevent the metal debris and dust remaining on the workpiece surface from polluting the discharge conveyor line 2 and subsequent process equipment.

[0024] The workpiece on the feed conveyor line 1 is hoisted onto the mounting frame 6 through the workshop's hoisting equipment. The electric rotary module 51 cooperates with the docking shaft 52 to drive the workpiece to rotate above the primary fence 8, and the dust or impurities existing on the workpiece before deburring are dumped into the primary fence 8. The rotating cylinder 7 cooperates with the truss 71 to lift the blow pipe 72 close to the bottom of the mounting frame 6 to blow away impurities under the workpiece.

[0025] After the workpiece enters the mounting frame 6 and is clamped, the workpiece can be turned over before deburring, and foreign matter such as impurities on its surface can be dumped into the primary fence 8. When the mounting frame 6 stops rotating and remains horizontal, the primary fence 8, the secondary fence 81 and the tertiary fence 82 can be lifted and the air pipe 72 can be used to blow air under the mounting frame 6 to blow away the impurities under the workpiece and drop them into the primary fence 8.

[0026] In this embodiment, the front end of the docking shaft 52 is fixedly connected to the middle of the rear end of the mounting frame 6, and the mounting frame 6 is deployed close to the robotic arm 3. The four sides of the mounting frame 6 and the four surfaces of the inner wall of the third-level fence 82 maintain isolation gaps. The left and right sides of the mounting frame 6 are fixed with a first clamping cylinder 61, and the two first clamping cylinders 61 are fixed with a first clamping plate 62 toward the execution end of the middle of the mounting frame 6. The front and rear sides of the mounting frame 6 are fixed with a second clamping cylinder 63, and the two second clamping cylinders 63 are fixed with a second clamping plate 64 toward the execution end of the middle of the mounting frame 6.

[0027] The first clamping cylinder 61 and the first clamping plate 62 cooperate to clamp the workpiece placed in the middle of the mounting frame 6 from the left and right sides, and the second clamping cylinder 63 and the second clamping plate 64 cooperate to clamp the workpiece placed in the middle of the mounting frame 6 from the front and back sides. The first clamping cylinder 61 and the second clamping cylinder 63 can clamp synchronously or in steps.

[0028] In this embodiment, a positioning groove 74 is provided at the top of the truss 71 to match the front end of the blowing pipe 72. The external thread of the top positioning groove 74 of the truss 71 is connected to a fastening bolt 75. The middle part of the truss 71 is movably connected to a positioning pin 76, and the rear end of the positioning pin 76 is movably connected to a positioning bearing 77.

[0029] The truss 71 completes the installation position locking of the blowing pipe 72 through the positioning groove 74 and the fastening bolt 75, that is, the direction of the air hole 73 is adjusted as the truss 71 is deflected by the rotating cylinder 7, ensuring that the air hole 73 can effectively blow off the workpiece under the mounting frame 6.

[0030] The rotating cylinder 7 drives the truss 71 to deflect, and the blowing pipe 72 is close to the bottom of the mounting frame 6. At this time, the positioning pin 76 on the truss 71 cooperates with the guide hole of the third-level fence 82 to complete the lifting of the third-level fence 82 in the middle of the first-level fence 8. The positioning bearing 77 cooperates with the positioning pin 76 to rotate in front of the third-level fence 82.

[0031] In this embodiment, the bottom of the first-level fence 8 is detachably connected to the bottom of the frame 4, and the front and rear sides of the left and right ends of the first-level fence 8 are movably connected with the first connecting rod 83. The top of the first connecting rod 83 is slidably connected to the outer side of the third-level fence 82. The middle of the first connecting rod 83 is movably connected with a connecting pin 84. The other end of the connecting pin 84 is movably connected to the middle of the second connecting rod 85. The bottom of the second connecting rod 85 is slidably connected to the top of the first-level fence 8. The top of the second connecting rod 85 is movably connected to the outer side of the third-level fence 82. The middle part of the connecting pin 84 is movably connected to the outer side of the second-level fence 81. The left and right sides of the front of the third-level fence 82 are fixed with guide holes for matching the positioning pins 76. The front of the third-level fence 82 is movably connected to the outer side of the positioning bearing 77. The top of the third-level fence 82 extends to the bottom of the mounting frame 6.

[0032] The third-level fence 82 is lifted by the positioning pin 76, and the third-level fence 82 drives the secondary fence 81 to rise from the middle of the first-level fence 8 through the scissor arm structure composed of the first connecting rod 83, the second connecting rod 85 and the connecting pin 84. At this time, the first-level fence 8, the second-level fence 81 and the third-level fence 82 cooperate to form a shielding structure under the mounting frame 6 to prevent impurities on the workpiece from falling outside the processing area, and effectively recover the dust and impurities generated by the deburring processing of the workpiece. The metal debris and other impurities collected in the first-level fence 8 can be cleaned up by cleaning personnel or relevant staff in the factory area.

[0033] In the deburring of the workpiece, automated components such as the robot arm 3 are used, and the space around the equipment is compact. When deploying the exhaust filtration equipment, it is necessary to consider the possible path interference between the corresponding pipeline and the robot arm 3, the rotatable mounting frame 6 and the configured lifting equipment. At the same time, compared with the current workers in the workshop directly using an air gun to blow the surface of the workpiece, this type of operation is more likely to cause impurities on the surface of the workpiece to be directly dispersed throughout the deburring process area. The use of this equipment to flip the workpiece over to dump impurities and blow air for cleaning after shielding treatment can effectively avoid the occurrence of dust leakage during the workpiece deburring operation, and complete the harmless collection and treatment of the deburring impurities and dust of the workpiece.

[0034] The above-mentioned embodiments only express a certain implementation method of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent of the present invention shall be based on the attached claims.
