Description

Technical Field

[0001] The present invention relates to the field of cutting equipment, and more particularly to a cutting equipment for producing television hardware back panels. Background Art

[0002] After stamping and forming the metal back panel of a television, the excess material on the back panel needs to be removed. This requires cutting equipment, such as the Chinese patent document CN107962612A, entitled "A Device for Cutting Offset Material on a Television Back Panel," which discloses a cutting device specifically for television back panels. This device uses four first servo motors to drive four screws, which in turn drive four second servo motors to move back and forth, allowing the cutting blades on these motors to cut the offset material on each of the four sides of the television back panel. However, this structure requires four first servo motors to drive the four screws, resulting in multiple power components, a relatively complex structure, and high costs. Furthermore, during processing, the television back panel is placed on a support plate without a clamping mechanism, relying solely on the side panels of the box surrounding the support plate for positioning. This makes it difficult to secure the television back panel properly, and it easily shifts during cutting, resulting in uneven cuts. Furthermore, it can only process television back panels of the same specification, resulting in poor adaptability. Summary of the Invention

[0003] In view of the above-mentioned deficiencies in the prior art, the present invention provides a cutting device which has fewer power components, is applicable to television back panels of different specifications, and can well fix the television back panel during processing.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions:

The two ends of the connecting plate are respectively fixedly connected to the bottom ends of the first telescopic member and the second telescopic member. The elastic member rests on the bottom surface of the connecting plate. One end of the lever member is hinged to the bottom surface of the workbench and the other end rests on the top surface of the connecting plate. The pushing assembly acts on one side of the lever member close to the hinge. The first positioning plate and the second positioning plate are respectively arranged at the top ends of the first telescopic member and the second telescopic member.

[0009] Furthermore, the pushing assembly includes an upper cross bar, a lower cross bar, two connecting columns and several top columns.

[0012] Furthermore, the second screw is located between the two second guide rails and close to one of the second guide rails. The second driving mechanism also includes an adjusting member, which is threadedly connected to one end of the second slide close to the second screw. The end of the adjusting member passes through the second slide and abuts against the second guide rail.

[0013] Furthermore, the second driving mechanism also includes two hangers, which can be moved parallel to the bracket and can be locked at both ends of the second slide, and the other two cutting machines are fixedly connected to the two hangers.

[0014] Furthermore, the clamping mechanism includes a pressure rod, a pressure plate and a driving member. The pressure rod is hinged on the workbench, and the driving member is fixedly connected to the bottom surface of the workbench and is used to push one end of the pressure rod to rotate up and down.

[0026] Reference Figures 1 to 4A cutting device for producing a metal back panel of a television set includes a work plate 10 for placing the metal back panel and four cutting machines 20, and further includes:

[0027] The positioning mechanism is retractably arranged near the work plate 10 and is used to adjust the positioning position to position hardware back plates of different specifications so that the hardware back plates are placed on the work plate 10 in the correct posture;

[0028] The clamping mechanism is used to clamp the top surface of the metal back plate placed on the work plate 10, and when clamping, pushes the positioning mechanism to retract away from the work plate 10 so that it does not affect the cutting operation;

[0029] The first driving mechanism is used to fixedly connect the two cutting machines 20 and simultaneously drive the two cutting machines 20 to move back and forth to cut two opposite sides of the hardware back plate;

[0030] The second driving mechanism is used to fixedly connect the other two cutting machines 20 and can simultaneously drive the two cutting machines 20 to move back and forth to cut the other two opposite sides of the hardware back plate.

[0031] In one embodiment, if Figures 1 to 3 The cutting device also includes a workbench 1 as a carrying platform, and the working plate 10, the positioning mechanism, the pressing mechanism, the first driving mechanism and the second driving mechanism are all arranged on the workbench 1.

[0032] In one embodiment, if Figures 1 to 4 A gantry-type bracket 11 is provided on the workbench 1, and the work plate is provided in the middle of the top surface of the bracket 11. Both sides of the workbench 1 are provided with a gantry-type top frame 12 that spans the first driving mechanism.

[0033] In one embodiment, if Figure 1 and Figure 4The first driving mechanism includes two first guide rails 21, a first slide 22, a first screw 23, and a first motor 24. The two first guide rails 21 are arranged parallel to the workbench 1 and are respectively located on both sides of the bracket 11. The first slide 22 is located below the bracket 11 and its two ends are slidably connected to the two first guide rails 21. The first screw 23 is arranged parallel to the first guide rails 21 and is threadedly connected to the first slide 22. The first motor 24 is located on one side of the workbench 1 and its output end is fixedly connected to the first screw 23. The two cutting machines 20 can be moved toward the bracket 11 and are lockable at both ends of the first slide 22. T-slots and T-blocks are provided at both ends of the first slide 22. Screws are passed through the mounting plate of the first motor 24 and are threadedly connected to the T-block in the T-slot. When loosened, the cutting machine 20 can move along the T-slot. After tightening the screws, the cutting machine 20 can be fixed. Since the first screw 23 is located at a low position and is easily contaminated by the cut hardware powder, an existing bellows expansion tube (not shown) can be sleeved on the first screw 23 to effectively isolate the hardware powder.

[0034] In one embodiment, if Figure 1 and Figure 4 The second driving mechanism includes two second guide rails 31, a second slide 32, a second screw 33 and a second motor 34. The two second guide rails 31 are arranged parallel to the top frame 12 and perpendicular to the first guide rail 21. The two ends of the second slide 32 are respectively slidably connected to the two second guide rails 31. The second screw 33 is arranged parallel to the second guide rail 31 and is threadedly connected to the second slide 32. The second motor 34 is arranged on the workbench 1 and the output end is fixedly connected to the second screw 33. The remaining two cutting machines 20 can be moved parallel to the bracket 11 and can be locked at the two ends of the second slide 32. Preferably, the second driving mechanism also includes two hangers 35. The two hangers 35 can be moved parallel to the bracket 11 and can be locked at the two ends of the second slide 32. The remaining two cutting machines 20 are respectively fixedly connected to the two hangers 35, so that the remaining two cutting machines 20 are at the same height as the two cutting machines 20 on the first slide 22.

[0035] In the above embodiment, the second screw 33 is located between the two second guide rails 31 and close to one of the second guide rails 31. This arrangement can make room in the middle, making it convenient to take and place the hardware back plate. Since the second screw 33 is arranged close to one of the second guide rails 31, the force applied to the second slide 32 when it is driven to move is relatively unbalanced. Therefore, an adjustment member 36 is provided to increase the friction between the second slide 32 and the second guide rail 31 on the side of the second screw 33. Specifically, the adjustment member 36 is threadedly connected to one end of the second slide 32 close to the second screw 33, and the end of the adjustment member 36 passes through the second slide 32 and abuts against the second guide rail 31. When the adjustment member 36 is tightened, the friction force increases, and when it is loosened, the friction force decreases. The adjustment member 36 is set according to actual needs.

[0036] In one embodiment, if Figure 1 and Figure 4 The clamping mechanism comprises a pressure rod 41, a pressure plate 42, and a driver 43. The pressure rod 41 is hinged to the workbench 1. The driver 43 is fixedly connected to the bottom surface of the workbench 1 and is used to push one end of the pressure rod 41 up and down. The pressure plate 42 is universally connected to the other end of the pressure rod 41 and can rotate downward with the other end until it contacts the work board 10. When the driver 43 pushes one end of the pressure rod 41 upward, the other end drives the pressure plate 42 downward until it presses against the TV hardware backboard, at which point the positioning mechanism retracts away from the work board 10. The driver 43 is preferably a pneumatic cylinder. The cylinder's output end is fixedly connected to a concave plate 44 with a strip groove. One end of the pressure rod 41 is connected to the strip groove via a pin. The universal connection between the pressure plate 42 and the other end of the pressure rod 41 accommodates hardware backboards of varying thicknesses, allowing for self-adjustable clamping.

[0037] In one embodiment, referring to Figures 1 to 4 The positioning mechanism includes a first positioning plate 51, a second positioning plate 52, a telescopic assembly, a push assembly, and a lever 55. The telescopic assembly is vertically movable and extends through the workbench 1. The first and second positioning plates 51, 52 are located at the top of the telescopic assembly and can be adjusted relative to the workbench 1 to respectively abut against two adjacent edges of the hardware backplate. The push assembly is vertically movable and extends through the workbench 1. When it reaches its highest position, its top edge extends beyond the work plate 10. The lever 55 is located below the workbench 1 and, driven by the push assembly, causes the telescopic assembly to move at a greater amplitude than the push assembly. The lever 55 amplifies the force of the lever 55, causing a small downward movement of the push assembly to cause a larger downward movement of the telescopic assembly. This allows the telescopic assembly, along with the first and second positioning plates 51, 52 thereon, to move away from the work plate 10, that is, below the first slide 22, without hindering the back-and-forth movement of the first slide 22.

[0038] In one embodiment, referring to Figures 1 to 4The telescopic assembly includes a first telescopic member 531, a second telescopic member 532, a connecting plate 533, a guide column 534 and an elastic member 535. The first telescopic member 531 and the second telescopic member 532 are respectively arranged on the workbench 1 for moving up and down. The guide column 534 is vertically fixedly connected to the bottom surface of the workbench 1. The connecting plate 533 can move up and down and cooperate with the guide column 534 to be connected. The two ends of the connecting plate 533 are respectively fixedly connected to the bottom ends of the first telescopic member 531 and the second telescopic member 532. The elastic member 535 abuts the bottom surface of the connecting plate 533. One end of the lever member 55 is hinged to the bottom surface of the workbench 1 and the other end abuts the top surface of the connecting plate 533. The pushing assembly acts on one side of the lever member 55 close to the hinge. The first positioning plate 51 and the second positioning plate 52 are respectively arranged at the top ends of the first telescopic member 531 and the second telescopic member 532.

[0039] In one embodiment, referring to Figures 1 to 4 The pushing assembly includes an upper crossbar 541, a lower crossbar 542, two connecting posts 543, and a plurality of top posts 544. The two connecting posts 543 are located on either side of the workbench 1 and are disposed on the workbench 1 so as to be movable up and down. The ends of the upper crossbar 541 are fixedly connected to the upper ends of the two connecting posts 543, and the ends of the lower crossbar 542 are fixedly connected to the lower ends of the two connecting posts 543. The middle portion of the lower crossbar 542 acts on the lever 55. A plurality of top posts 544 are disposed on the upper crossbar 541. When the upper crossbar 541 is in its highest position, the top ends of the top posts 544 extend beyond the work board 10. The number of top posts 544 is no less than three, and preferably four as shown in the accompanying drawings. Two upper crossbars 541 are provided, one on each side of the bracket 11. Each upper crossbar 541 is provided with two top posts 544, and the top ends of the top posts 544 can pass through and extend beyond the work board 10. The metal back plate is placed on the workbench 1 and supported by the top of the top column 544. It is temporarily not in contact with the work plate 10. Under the pressure of the pressing plate 42 of the clamping mechanism, the top column 544 is pushed down and retracted until the metal back plate is in contact with the work plate 10.

[0040] The hanger 35 and the second slide 32 , the first positioning plate 51 and the first telescopic member 531 , and the second positioning plate 52 and the second telescopic member 532 are all connected by T-slots, T-blocks and screws, just like the connection between the cutting machine 20 and the first slide 22 .

[0041] The above embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the embodiments as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
