Description

Technical Field

[0001] This utility model relates to the field of chassis manufacturing technology, specifically a cutting device for chassis manufacturing. Background Technology

[0002] In the chassis manufacturing process, the cutting process requires processing metal sheets (such as cold-rolled steel sheets and aluminum alloy sheets) into blanks that conform to the chassis dimensions. The cutting accuracy and efficiency directly affect the quality of subsequent processes such as bending and drilling, as well as the overall production progress. With the expansion of chassis applications, their size specifications are becoming increasingly diversified, and the requirements for the positioning accuracy, adaptability, and ease of operation of cutting equipment are constantly increasing.

[0003] Currently, traditional chassis manufacturing cutting equipment relies heavily on manual visual positioning of chassis panels, lacking precise scales and limiting structures, resulting in large cutting position errors. Furthermore, the clamping force of some devices is uncontrollable, which can easily lead to damage to the chassis panels or displacement during cutting, affecting the quality of the cut. In view of this, we propose a new cutting equipment for chassis manufacturing. Utility Model Content

[0012] This utility model provides a cutting device for chassis manufacturing. It has the following advantages: (1) The cutting equipment for chassis production uses a bidirectional screw to drive the movable seat and the limit rod to adjust synchronously, which can accurately limit chassis panels of different widths; the indicator arrow and the scale work together to use the observation plate as the reference surface to quantitatively adjust the position of the gantry carriage and determine the cutting starting point; the pressure plate driven by the electric cylinder base works with the anti-slip rubber pad to stably press the chassis panel and prevent the panel from shifting during cutting.

A gantry carriage 2 is slidably connected to the top of the machine body 1. A moving device 3 is installed on the gantry carriage 2. The moving device 3 is a linear module equipped with a servo motor drive, which has high positioning accuracy (here, it is composed of two linear modules connected together, which can realize lifting and horizontal movement). It can drive the laser cutting head 12 to move precisely along the gantry carriage 2 to meet the needs of different cutting paths. This is existing technology. A clamping component 4 is installed on the machine body 1. The clamping component 4 includes two sets of side seats 41, which are distributed on the gantry. On both sides, multiple sets of laser rack plates are arranged between the two sets of placement side seats 41 to facilitate laser cutting. The placement side seats 41 are fixedly connected to the top of the machine body 1. A support frame 42 is set above the placement side seats 41. An electric cylinder base 43 is fixedly connected to the top of the support frame 42. A pressure plate 44 is fixedly connected to the output end of the electric cylinder base 43. A bidirectional screw 45 is rotatably connected to the inner wall of the placement side seats 41. A rotating block 46 is fixedly connected to both ends of the bidirectional screw 45. The rotating block 46 is a hexagonal metal block that can be rotated with a wrench to facilitate manual adjustment of the bidirectional screw 45 and saves effort in operation.

[0020] In this utility model, the outer wall of the bidirectional screw 45 is threadedly connected to a movable seat 47, and the top of the movable seat 47 is fixedly connected to a limiting rod 48. Two sets of limiting rods 48 are provided on a set of movable seats 47. The limiting rods 48 are metal rods that are perpendicular to the surface of the placement side seat 41. The four sets of limiting rods 48 limit the machine box plate from the side (two-two distributed on one side) to prevent the plate from shifting laterally during cutting.

[0021] Furthermore, an electric cylinder base 2 13 is fixedly connected to the inner wall of the machine body 1. The output end of the electric cylinder base 2 13 is fixedly connected to the outer wall of the gantry slide 2. A slide rail 14 is fixedly connected to the inner wall of the machine body 1. The inner wall of the gantry slide 2 is slidably connected to the outer wall of the slide rail 14. The slide rail 14 is a linear guide rail with a chrome-plated surface for rust prevention. The clearance between the slide rail 14 and the slider of the inner wall of the gantry slide 2 is ≤0.02mm, ensuring that the gantry slide 2 slides smoothly without deviation.

[0022] Furthermore, a guide rod 5 is fixedly connected to the top of the clamping plate 44. The guide rod 5 passes through the support frame 42 and is slidably connected to the support frame 42. A guide rail 6 is fixedly connected to the inner wall of the side seat 41. The inner wall of the movable seat 47 is slidably connected to the outer wall of the guide rail 6. The guide rail 6 is a rectangular guide rail that matches the sliding groove at the bottom of the movable seat 47, assisting the movable seat 47 to move in a straight line and further ensuring the accurate position of the limit rod 48. An observation plate 7 is fixedly connected to the outer wall of the side seat 41. A material passage 8 is opened on the observation plate 7. The observation plate 7 is a reference surface. Before cutting, it is ensured that one end of the plate passes through the material passage 8.

[0023] Furthermore, the outer wall of the gantry carriage 2 is fixedly connected with an indicator arrow 9, the top of the machine body 1 is fixedly connected with a scale 10, and the top of the machine body 1 is fixedly connected with a roller frame 11. The roller frame 11 is a metal frame with rollers installed, which can reduce the frictional resistance when the chassis plate moves, facilitate the operator to feed and pick up materials, and avoid scratching the plate. The moving device 3 is equipped with a laser cutting head 12. The laser cutting head 12 is a high-precision fiber laser cutting head 12, which has a fast cutting speed and a flat cut. It can be adapted to chassis plates of different thicknesses (such as cold-rolled steel plates and aluminum alloy plates) to meet the cutting needs of chassis production. This is existing technology and will not be described in detail.

[0024] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. The components are all general standard parts or components known to those skilled in the art. Their structure and principle can be known by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here.

[0025] In use, first place the chassis panel to be cut on the roller frame 11 at the top of the machine body 1, push the panel so that its edges fit against the side seat 41, use a wrench to rotate the rotating block 46 to drive the bidirectional screw 45 to rotate, so that the two sets of movable seats 47 move synchronously along the guide rail 6, and the limit rod 48 moves closer to both sides of the chassis panel until it is tightly against the panel to complete the lateral positioning; start the electric cylinder seat 43 to drive the pressing plate 44 to descend along the guide rod 5, press the top of the chassis panel tightly, and complete the fixing; According to the cutting requirements, start the electric cylinder base 2 13 to drive the gantry slide 2 to move along the slide rail 14. Combined with the indicator arrow 9 and the scale 10, adjust the laser cutting head 12 to the cutting starting point. Then start the moving device 3 and the laser cutting head 12. The moving device 3 drives the cutting head to cut along the gantry slide 2 according to the preset path. The operator monitors the cutting situation in real time through the material passage 8 of the transparent observation plate 7. After the cutting is completed, the electric cylinder base 43 drives the pressure plate 44 to rise, and the rotating block 46 rotates in the opposite direction to release the limit rod 48. Push the machine box plate to be taken out along the roller frame 11, and the next piece of plate can be cut.
