Description

Technical Field

[0001] This utility model relates to the field of sheet metal cutting technology, and in particular to a positioning and cutting device. Background Technology

[0002] Sheet metal cutting is the process of cutting large sheets of sheet metal into specific sizes and shapes according to design drawings or actual needs. This is a fundamental step in sheet metal processing, ensuring that the final product meets design requirements and functional requirements. When sheet metal is placed on a workbench, if it is tilted, direct cutting will cause the cutting path to deviate, resulting in excessive excess material and wasted sheet metal.

[0003] In existing technologies, existing equipment mostly uses a single-direction clamping method to fix the sheet metal, which cannot simultaneously control the displacement of the sheet metal in both horizontal and vertical directions. Especially when cutting thicker sheets, the cutting force can easily cause the sheet metal to jump up and down or sway left and right, affecting the cutting quality and posing safety hazards. Therefore, we propose a positioning cutting device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a positioning and cutting device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A positioning and cutting device includes a frame, a cutting frame fixedly connected to the top of the frame, a drive roller rotatably connected inside the cutting frame, a plurality of guide rollers rotatably connected inside the cutting frame, a motor fixedly connected to the outer wall of the cutting frame, a bidirectional lead screw fixedly connected to one end of the motor output shaft, two moving blocks threadedly fitted on the outer wall of the bidirectional lead screw, a deep groove ball bearing fixedly connected to the top of each of the two moving blocks, a threaded rod fixedly connected to the inner ring of each of the two deep groove ball bearings, an L-shaped plate threadedly fitted to the top of each of the two threaded rods, a guide assembly provided inside the cutting frame, and a lower pressure roller rotatably connected to the outer wall of each of the two L-shaped plates.

[0008] Preferably, the cutting frame is rotatably connected to an upper blade and a lower blade.

[0009] Preferably, the outer wall of the cutting frame has a circular hole, the inner wall of the circular hole is rotatably connected to the outer wall of the motor output shaft, the motor is supported by an existing bracket, and the bracket is fixedly connected to the cutting frame.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

In addition, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0022] Depend on Figures 1-4 As shown, a positioning and cutting device is disclosed, including a frame 1. A cutting frame 2 is fixedly connected to the top of the frame 1. An upper blade 3 and a lower blade 4 are rotatably connected inside the cutting frame 2 via an existing shaft. A drive roller 5 is rotatably connected inside the cutting frame 2 via an existing shaft. Multiple guide rollers 6 are rotatably connected inside the cutting frame 2 via an existing shaft. The drive roller 5 is rotated by an existing drive device, which can drive the plate to move. The outer wall of the drive roller 5 is provided with anti-slip texture.

[0023] A motor 7 is fixedly connected to the outer wall of the cutting frame 2. The motor 7 can be a servo motor. A circular hole is opened on the outer wall of the cutting frame 2. The inner wall of the circular hole is rotatably connected to the outer wall of the output shaft of the motor 7. A bidirectional lead screw 8 is fixedly connected to one end of the output shaft of the motor 7. A roller bearing is fixedly sleeved on one end of the bidirectional lead screw 8. The outer ring of the roller bearing is fixedly connected to the inner wall of the cutting frame 2. The motor 7 drives the bidirectional lead screw 8 to rotate.

[0024] Two moving blocks 9 are threaded on the outer wall of the bidirectional lead screw 8. The motor 7 drives the bidirectional lead screw 8 to rotate, causing the two moving blocks 9 to move towards or away from each other, thereby achieving positioning adjustment in the width direction. The top of each of the two moving blocks 9 is fixedly connected to a deep groove ball bearing 10, and the inner ring of each of the two deep groove ball bearings 10 is fixedly connected to a threaded rod 11. The deep groove ball bearings 10 assist the threaded rod 11 to rotate stably.

[0025] Both threaded rods 11 have L-shaped plates 12 threaded onto their tops. Nuts can be added to the outer walls of the threaded rods 11. Rotating the nuts presses them against the bottom of the L-shaped plates 12, preventing the threaded rods 11 from rotating easily. The outer walls of both L-shaped plates 12 are rotatably connected to lower pressure rollers 15 via existing shafts. Rotating the threaded rods 11 can adjust the height of the L-shaped plates 12, ensuring that the lower pressure rollers 15 maintain appropriate contact pressure with the surface of the material. The lower pressure rollers 15 are rotated using existing drive equipment, which can convey the material.

[0026] The cutting frame 2 is equipped with a guide assembly, which includes two guide rods 14. The outer wall of the guide rod 14 is slidably connected to the inner wall of the strip groove 13. The outer walls of the two L-shaped plates 12 are each provided with two strip grooves 13. The two ends of the two guide rods 14 are fixedly connected to the inner wall of the cutting frame 2. The cooperation between the guide rods 14 and the strip grooves 13 ensures the stability of the adjustment process.

[0027] Working principle: During use, the board is placed on multiple guide rollers 6. The rotation of the drive roller 5 drives the board to move between the upper blade 3 and the lower blade 4. For thinner boards, existing slitting blades can be used, and for thicker boards, existing circular saws are used for cutting. The upper blade 3 and the lower blade 4 are rotated by existing drive equipment. When positioning and cutting boards of different thicknesses and widths, the motor 7 drives the bidirectional lead screw 8 to rotate. The rotation of the bidirectional lead screw 8 drives the two moving blocks 9 to move relative to each other. The relative movement of the two moving blocks 9 drives the two threaded rods 11 and the two L-shaped plates 12 to move relative to each other. The relative movement of the two L-shaped plates 12 makes them contact the two sides of the board to prevent it from tilting. At the same time, the two threaded rods 11 can be rotated to drive the two L-shaped plates 12 to move up and down, which in turn drives the two lower pressure rollers 15 to move up and down, so that the outer walls of the two lower pressure rollers 15 contact the top of the board to position it and prevent it from moving up and down during cutting.

[0028] It should be noted that when actually put into use, an existing PLC controller can be added. The PLC controller is electrically connected to motor 7 to facilitate the control of the overall operation.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art.
