Description

Technical Field

[0001] The invention relates to the field of cutting technology, in particular to a lampshade cutting device which is easy to clamp. Background Art

[0002] The laser cutting machine is a machine that focuses the laser emitted from a laser into a high-power density laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting point or boiling point. At the same time, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a slit is eventually formed in the material, thereby achieving the purpose of cutting. Laser cutting machines are widely used and have been used in the processing of lampshades for a long time.

[0003] However, in the current lampshade laser cutting device, the lampshade is generally clamped and fixed by drilling a hole at the top of the lampshade, then using a cross bar to penetrate the hole and then using a clamp on the cross bar to clamp and fix the lampshade. This process is very cumbersome and requires damage to the workpiece. In addition, in the process of processing the lampshade, the waste cut from the lampshade and the hole are prone to stick together due to the burrs. If they cannot be separated in time, the burrs will cool down and the waste will stick to the holes, which requires manual separation by the staff later. For this reason, we propose a lampshade cutting device that is easy to clamp. Summary of the invention

[0039] The supporting mechanism 6 includes a supporting mounting plate 61, on which a connecting tube 12 is arranged, and the supporting mounting plate 61 is arranged on the clamping plate 52 through the connecting tube 12, and a second rotating plate 62 is arranged at the other end of the connecting sleeve rod 11, and the supporting mounting plate 61 passes through the side wall of the supporting mounting plate 61, and a plurality of second connecting rods 64 are arranged on the second rotating plate 62, and the second connecting rods 64 are opposite to the first connecting rod 55, and the second rotating plate 62 is provided with a supporting rod 63 through the second connecting rod 64, and the supporting rod 63 is slidably arranged on the supporting mounting plate 6 1, the support rod 63 is set to be flat, and the support mounting plate 61 and the clamping plate 52 are rotated synchronously through the connecting tube 12 to avoid friction between the support rod 63 and the inner wall of the lampshade. At the same time, the second connecting rod 64 and the first connecting rod 55 are in opposite directions. When the second rotating disk 62 rotates in the same direction as the first rotating disk 53, the second connecting rod 64 and the first connecting rod 55 drive the support rod 63 and the extension rod 541 to move in opposite directions, and the support rod 63 is set to be flat, so as to reduce the contact area between the support rod 63 and the inner wall of the lampshade.

[0040] The striking mechanism 13 includes a mounting box 131, which is arranged on the support rod 63. A wedge block 1322 is slidably arranged in the mounting box 131.

The moving rod 133 penetrates the side wall of the installation box 131. When the moving rod 133 moves, the top support block 1331 is pushed, so that the striking rod 132 is raised through the wedge block 1322. The wedge block 1322 can be reset under the action of the second reset spring 1321, so that the striking rod 132 strikes the inner wall of the lampshade.

[0041] A sliding groove 71 is provided on the limiting seat 7, and a contact platform 72 is provided on both sides of the sliding groove 71. There is a smooth transition between the contact platform 72 and the sliding groove 71. The contact platform 72 is higher than both sides of the sliding groove 71. The contact platform 72 is movably connected to the contact arc seat 54. A coaxial reversing mechanism 9 is slidably provided in the sliding groove 71. By providing the contact platform 72, the contact arc seat 54 can be squeezed, thereby causing the contact arc seat 54 to be displaced.

[0042] The coaxial reversing mechanism 9 includes a sliding seat 91, which is slidably arranged in the sliding groove 71, and the through rod 10 is rotatably arranged at one end of the sliding seat 91, and the other end of the sliding seat 91 is rotatably connected to the mounting sleeve rod 511, and an active bevel gear 94 is arranged on the through rod 10, and a driven bevel gear 95 is arranged on the mounting sleeve rod 511. A vertical rod 92 is arranged on the sliding seat 91, and the sliding seat 91 is rotatably arranged with a connecting bevel gear 93 through the vertical rod 92, and the two sides of the connecting bevel gear 93 are respectively connected to the active bevel gear 94 and the driven bevel gear 95, and the active bevel gear 94 and the driven bevel gear 95 are rotated in opposite directions through the setting of the connecting bevel gear 93, so that the driving bevel gear 94 and the driven bevel gear 95 rotate in opposite directions, thereby making the driving disk 8 and the supporting mounting disk 61 rotate in opposite directions, so that the moving rod 133 walks on the surface of the driving disk 8.

[0043] The driving disk 8 is fixedly set on the through rod 10, and the driving disk 8 is rotatably connected to the supporting mounting disk 61 through the through rod 10. A plurality of arc-shaped protrusions are set on the driving disk 8, and the moving rod 133 is movably connected to the arc-shaped protrusions on the driving disk 8. Through the plurality of arc-shaped protrusions, the moving rod 133 that moves on the surface of the driving disk 8 makes reciprocating motion.

[0044] A transverse movement mechanism 4 is arranged on the workbench 1, and the transverse movement mechanism 4 includes a transverse movement motor 41. A screw rod 411 is arranged at the output end of the transverse movement motor 41. The screw rod 411 is arranged on the workbench 1. A track 42 is arranged on the workbench 1. A transverse movement seat 43 is slidably arranged on the track 42. A mounting seat 431 is arranged on the transverse movement seat 43. The mounting seat 431 is threadedly arranged on the screw rod 411. The rotating motor 3 is arranged on the transverse movement seat 43, and the rotating motor 3 is slidably connected to the workbench 1 through the transverse movement seat 43.

[0045] Before use, the lampshade is put on the lower clamping claw 521, and the traverse motor 41 is started to make the screw rod 411 move, thereby driving the traverse seat 43 to move on the track 42, so that the contact arc seat 54 moves on the limiting seat 7. When the contact arc seat 54 moves to the contact platform 72, the contact platform 72 squeezes the contact arc seat 54, so that the contact arc seat 54 shrinks, and then the contact arc seat 54 rotates the first rotating disk 53 through the first connecting rod 55, thereby driving multiple upper clamping claws 542 to approach the lower clamping claw 521 at the same time, so as to clamp the lampshade, thereby avoiding the traditional method of drilling a hole at the top of the lampshade, clamping and fixing the lampshade through the hole, and at the same time, the contact arc seat 54 moves on the limiting seat 7, so as to facilitate the clamping of the lampshade;

[0046] When the first rotating disk 53 rotates, the first rotating disk 53 causes the second rotating disk 62 to rotate synchronously through the connecting rod 11. Since the second connecting rod 64 and the first connecting rod 55 are in opposite directions, the second rotating disk 62 causes the plurality of supporting rods 63 to expand simultaneously through the second connecting rod 64, thereby supporting the inner wall of the lampshade, thereby preventing the lampshade from being deformed when the laser head 2 contacts the lampshade as more and more holes are cut during the lampshade cutting process, thereby causing inaccurate cutting.

[0047] When entering the cutting stage, the motor 3 is rotated to rotate the chuck 31, thereby rotating the through rod 10 fixed on the chuck 31. When the through rod 10 rotates, the connecting bevel gear 93 is rotated through the active bevel gear 94 on the through rod 10, and then the installation sleeve rod 511 is driven to rotate in the opposite direction on the through rod 10 through the driven bevel gear 95. Since the supporting installation disk 61 and the clamping disk 52 are connected through the connecting tube 12, and the driving disk 8 is arranged on the through rod 10, the driving disk 8 and the supporting installation disk 61 are rotated in the opposite direction, so that the moving rod 133 is driven. The driving disk 8 moves on the moving disk 8. Since a plurality of arc-shaped protrusions are provided on the driving disk 8, when the moving rod 133 conflicts with the arc-shaped protrusion, the top support block 1331 is pushed, so that the striking rod 132 is lifted up through the wedge block 1322. When the moving rod 133 leaves the arc-shaped protrusion, the wedge block 1322 is reset under the action of the second reset spring 1321, so that the striking rod 132 strikes the inner wall of the lampshade. In this way, when the waste cut off from the lampshade is adhered to the hole due to the burr, the waste is separated from the hole by striking, so as to avoid the burr cooling and sticking due to the untimely separation.
