DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example
[0025] See also Figures 1 to 5 The utility model provides a technical solution: a bending part processing fixing structure, including a pillar assembly, including a support 11, a rotating column 12 connected to the support 11 through a bearing, and a supporting rod 13 rotatably connected to the top of the rotating column 12 through a pin. The support 11 is placed on the processing table, and the rotating column 12 and the supporting rod 13 support the support plate 21 to fix the L-shaped bending part D on the fixed support plate 22. Figure 1As shown, the support rod 13 can be rotated along the c direction to a suitable angle to change the angle and position of the bending part D, so as to facilitate the grinding and deburring of its outer surface, such as the b2 surface and a2 surface of the bending part D. It can also be rotated in the opposite direction of the c direction to grind and deburr the a1 surface and b1 surface of the bending part D. In addition, it is also possible to rotate along the axial direction of the rotating column 12 itself to achieve the change of the angle of the rotating column 12 and the support rod 13 and the support plate 21, so that different positions on the bending part D can be ground; the supporting assembly that supports the bending part D includes the support rod 13 and the support plate 21. The support plate 21 connected to the top, the fixed support plate 22 connected to the support plate 21, the pull-out plate 23 connected to the fixed support plate 22, and the electromagnet 24 installed at the center of the fixed support plate 22, the support plate 21 and the support upright 13 and the fixed support plate 22 are combined by conventional methods (such as screw connection), and the fixed support plate 22 and the electromagnet 24 are screwed together. When the bent part D made of magnetic steel is deburred, it can be placed on the fixed support plate 22, and the electromagnet 24 is operated to adsorb the bent part D, which can directly fix the bent part D, making it easy to change the position of the bent part D. The pull-out plate 23 is provided with a vertical limit block 231, and the pull-out plate 23 and the limit block 231 are screwed together. The pull-out plate 23 can be pulled outward to change the distance between the opposing pull-out plates 23, which is suitable for bending parts D of different widths. The limit block 231 plays the role of a limit rotation column 33; the pressing and fixing assembly includes a lifting plate 31 that slides through the pull-out plate 23, a fixed pressure plate 32 connected to the top of the lifting plate 31, and a rotating column 33 that is rotatably connected to the bottom end of the fixed pressure plate 32. The lifting plate 31 and the fixed pressure plate 32 are screwed together, and the fixed pressure plate 32 is screwed together. A fixed shaft 311 passing through the rotating column 33 is provided at the bottom, and a protrusion 331 is provided on the end of the rotating column 33. The fixed shaft 311 is screwed together with the fixed pressure plate 32 by a thread. The rotating column 33 rotates at the position of the fixed shaft 311 to change the position of the rotating column 33. The protrusion 331 and the rotating column 33 are injection molded as one piece. The protrusion 331 can be embedded in the limiting block 231 to limit the protrusion 331 and the rotating column 33, thereby ensuring the fixation of the position of the fixed pressure plate 32. The fixed pressure plate 32 can press the bending part D and can also be used to reinforce the bending part D made of non-magnetic steel.
[0026] In this embodiment, the pull-out plate 23 is a "U"-shaped structure, and the limit block 231 is a "T"-shaped structure. The limit block 231 is provided with a limiting groove that cooperates with the rectangular protrusion 331, which can change the position of the rotating column 33. The protrusion 331 can be embedded in the limit block 231 to limit the protrusion 331 and the rotating column 33, thereby ensuring the fixation of the position of the fixed pressure plate 32. The fixed pressure plate 32 can press the bending part D and can also be used to reinforce the bending part D made of non-magnetic steel.
[0027] In this embodiment, a rubber pad 321 is provided on the bottom surface of the side of the fixed pressure plate 32, and a through hole is provided at the center of the rubber pad 321. The rubber pad 321 is bonded to the fixed pressure plate 32 by glue. Through the designed deformable rubber pad 321, when the rubber pad 321 is close to the bending part D, the rubber pad 321 can be deformed under the action of external force, thereby fine-tuning the distance between the fixed pressure plate 32 and the fixed support plate 22.
[0028] In this embodiment, symmetrically distributed retraction parts are provided on the bottom surface of the fixed pressure plate 32, and the retraction parts include a fixed cylinder 41 threadedly connected to the fixed pressure plate 32, a telescopic column 42 sliding through the fixed cylinder 41, and a retraction spring 43 installed inside the fixed cylinder 41. The two ends of the retraction spring 43 are respectively connected to the fixed pressure plate 32 and the telescopic column 42. When the lifting plate 31 is moved vertically, when the telescopic column 42 contacts the pull-out plate 23, the telescopic column 42 telescopes and slides and squeezes the retraction spring 43. When the telescopic column 42 touches the pull-out plate 23 and encounters resistance, a reminder effect is provided, prompting the user to reduce the downward force so that the fixed pressure plate 32 moves slowly downward.
[0029] In this embodiment, the surfaces of the fixed support plate 22 and the electromagnet 24 on the same side are flush, the electromagnet 24 can absorb the magnetic bending part D, and the support plate 21 is a "U"-shaped structure.
[0030] In this embodiment, the bending part D includes a horizontal part and a bent vertical part, the opposite surfaces of the horizontal part are the b1 surface and the b2 surface, and the opposite surfaces of the vertical part are the a1 surface and the a2 surface. The fixed support plate 22 coincides with the b1 surface of the bending part D. The rotating column 12 is provided with an axis f that passes through the end of the supporting rod 13. There is friction resistance between the supporting rod 13 and the axis f. Under the action of friction resistance, the inclined supporting rod 13 can be kept stable. The vertical supporting rod 13 can be rotated up to 90 degrees in the c direction with the axis f as the axis core. The angle of the supporting rod 13 can be adjusted, and the supporting rod 13 can be rotated to an appropriate angle in the c direction to change the angle and position of the bending part D, so as to facilitate grinding and deburring of its outer surface, such as the b2 surface and a2 surface of the bending part D.
[0031] The working principle and use process of this utility model:
[0032] When deburring the outer surface of the bent part D, the bent part D made of magnetic steel is placed on the fixed support plate 22;
[0033] The electromagnet 24 is in contact with the b1 surface of the bending part D. The electromagnet 24 is charged and operates. The electromagnet 24 adsorbs the b1 surface of the bending part D, making it firmly fixed, and the position of the bending part D can be changed conveniently.

[0035] The rotating column 12 can also be rotated to change the angles of the rotating column 12, the supporting rod 13 and the support plate 21, so that different positions on the bending part D can be polished;
[0036] The pull-out plates 23 can be pulled outward to change the distance between the opposing pull-out plates 23 to accommodate bending parts D of different widths;
[0037] When the bending part D made of non-magnetic steel is placed on the fixed support plate 22, the lifting plate 31 is vertically moved downward to a suitable position so that the rubber pad 321 contacts the side of the bending part D, and the rubber pad 321 presses the bending part D;
[0038] By changing the position of the rotating column 33, the protrusion 331 can be embedded in the corresponding limiting block 231 to limit the protrusion 331 and the rotating column 33, thereby ensuring the fixed position of the fixed pressure plate 32. The fixed pressure plate 32 can press the bending part D and can also be used to reinforce the bending part D made of non-magnetic steel;
[0039] To sum up: there is a structural design that can conveniently adjust the position and direction of the workpiece, the fixed support plate 22 supports the bent part D, and the electromagnet 24 firmly adsorbs the bent part D. In addition, the rubber pad 321 on the downward fixed pressure plate 32 presses the bent part D, which can fix the bent part D made of steel and facilitate deburring processing.
