Description

Technical Field

[0001] The invention relates to the technical field of automobile processing, and in particular to a laser cutting device for automobile processing. Background Art

[0002] In the automobile processing process, the automobile parts are processed first, and then the various automobile parts are assembled to form an automobile. Automobile parts are the various units that constitute the entire automobile and a product that serves the automobile. There are many types of automobile parts. Air-conditioning systems, intake and exhaust systems, cooling systems, etc. all include pipe fittings. Pipe fittings require a variety of processing methods, including casting, forging, stamping, machining, laser cutting and pipe cutting technology, etc. During laser cutting, the pipe fittings will be cut by a laser cutting device.

[0003] Most laser cutting equipment is equipped with a mobile seat with a clamping function. The mobile seat clamps the pipe to be processed and moves it to the working area of ​​the laser cutting machine. Then the laser cutting machine starts to cut the pipe to be processed. However, during the process of cutting the pipe, the cutting head of the laser cutting machine focuses the laser beam into a small spot. When the high-energy laser beam acts on the material, it will melt and spray out, and a large amount of spatter will be generated during the laser cutting process, which poses a safety hazard. The slag generated by the spatter falls in large quantities in the working area and is difficult to clean, affecting subsequent cutting operations. Summary of the invention

[0004] The purpose of the present invention is to solve the above-mentioned technical problems and to provide a laser cutting device for automobile processing.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] The cam is an angular channel that is fixedly provided with a second end of the second stopper, the second end of the second stopper being engaged with the first and second stopper plates, the cam being arranged on a circle that is meshed with the second end of the second stopper plates.

[0008] As a further description of the above technical solution:

[0009] The supporting assembly includes a connecting sleeve and a mounting rod. The connecting sleeve is fixedly connected to the outer surface of the second tube body. Two slide plates are slidably arranged inside the connecting sleeve. The two slide plates are connected at opposite sides by a connecting spring. One end of the mounting rod movably penetrates into the second tube body and is rotatably embedded with a ball. The other end of the mounting rod is fixedly connected to one of the slide plates. A second adjusting bolt for squeezing the other slide plate is threadedly penetrated at one end of the connecting sleeve.

[0010] As a further description of the above technical solution:

[0011] The limiting member includes a mounting block rotatably arranged on the inner side of the support plate and a first adjusting bolt threadedly penetrating the mounting block. A notch groove for flipping the limiting baffle is opened on the surface of the second tube body, and the lower end surface of the first adjusting bolt contacts the outer surface of the limiting baffle.

[0012] As a further description of the above technical solution:

[0013] A collection box for collecting debris generated during the cutting process is provided at one end of the machine base.

[0014] As a further description of the above technical solution:

[0016] As a further description of the above technical solution:

[0017] There are two support plates and they are symmetrically arranged. Both sides of the mounting block are rotatably connected to the support plates through rotating shafts. The rotating shafts are sleeved with gears. One side of the fixing plate is provided with racks meshing with the gears.

[0018] As a further description of the above technical solution:

[0019] A three-jaw chuck for clamping pipe fittings is rotatably provided on one side of the movable seat, and a motor for driving the three-jaw chuck to rotate is provided inside the movable seat. The laser cutting machine, the motor and the driving machine are electrically connected to the controller respectively.

[0020] As a further description of the above technical solution:

[0021] The upper end of the machine base is provided with a vibration spring matched with the lower surface of the second tube body.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0023] In the present invention, by providing the first tube body, the second tube body and the through-mouth groove, the slag generated during the laser cutting process can fall onto the inner bottom surface of the second tube body and inside the pipe fitting.

The supporting component supports the pipe fitting so that a gap exists between the pipe fitting and the inner wall of the second pipe body, which is convenient for slag discharge. The restraining component positions the end of the pipe fitting so that the second pipe body is naturally deflected and the pipe fitting does not fall off. When the pipe fitting to be processed is further moved to extrude the cut pipe fitting, the second pipe body will flip downward, thereby causing the slide bar to contact and extrude the restraining block, causing the slide bar to slide and extrude the mounting block to deflect the mounting block, thereby releasing the extrusion limit on the limit baffle, so that the cut pipe fitting can be removed from the second pipe body.

[0025] In the present invention, a mounting block, a first adjusting bolt and a limit baffle are provided. The first adjusting bolt limits the limit baffle from flipping upward. The limit baffle is flipped upward due to the extrusion of the pipe to be processed, that is, the extrusion cutting length of the pipe to be processed is limited. The flipping degree of the limit baffle is adjusted by rotating the first adjusting bolt, thereby achieving the effect of adjusting the cutting length of the pipe, ensuring that the cutting length of the pipe to be processed is the same each time, and further improving the work efficiency.

DETAILED DESCRIPTION

[0035] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0036] like Figure 1-8As shown, a laser cutting device for automobile processing includes a machine base 1 and a controller 3 arranged on the outer surface of the machine base 1. A movable base 4 for clamping a pipe is slidably arranged on the upper end of the machine base 1. A driving machine 5 for driving the movable base 4 to move is arranged on one side of the machine base 1. A laser cutting machine 2 for cutting the clamped pipe is arranged on one side of the machine base 1. A first pipe body 6 is fixedly arranged on the upper end of the machine base 1. One end face of the first pipe body 6 is stepped and a second pipe body 8 is hingedly arranged on the lower end through a hinge 30. The second pipe body 8 is of the same specification as the first pipe body 6. A through groove 10 matching the laser cutting machine 2 is opened on the upper surface of the first pipe body 6. The through groove 10 is located at the first Above the second tube body 8, the laser cutting machine 2 cuts the pipe to be processed through the through-mouth groove 10. The slag in the cutting process falls on the inner bottom surface of the second tube body 8 and falls inside the tube. When the tube is cut, the second tube body 8 will naturally turn downward, and the slag inside the tube and the second tube body 8 will slide downward and be discharged. Then the moving seat 4 moves to drive the remaining pipes to be processed to move. The pipes to be processed will squeeze the inner wall of the second tube body 8, so that the second tube body 8 turns upward to restore its original state. A supporting component for supporting the tube is provided inside the second tube body 8, and a restraining component for restraining the end of the tube is provided on the outer surface of the second tube body 8;

[0037] The constraint assembly includes a fixed shell 13 fixedly arranged at the upper end of the second tube body 8 and a limit baffle 12 rotatably arranged at one side of the upper end of the second tube body 8. A support plate 14 is arranged at one side of the fixed shell 13. A limiter for limiting the flipping of the limit baffle 12 is arranged on the inner side of the support plate 14 through a rotating shaft. A gear 21 is sleeved on the outer side of the rotating shaft. A moving plate 17 is slidably arranged inside the fixed shell 13. The moving plate 17 is connected to the inner wall of the fixed shell 13 through a compression spring 18. A sliding rod is fixedly penetrated in the middle of the moving plate 17. 16, a fixed plate 19 is provided at one end of the slide bar 16, and a rack 20 meshing with a gear 21 is provided on one side of the fixed plate 19. A restraining block 15 matching with the other end of the slide bar 16 is provided at the upper end of the first tube body 6. The limit baffle 12 contacts the end of the pipe to be processed to limit the movement of the pipe to be processed. The limit baffle 12 remains in a downward hanging state under the action of its own gravity, that is, when the moving seat 4 drives the pipe to be processed to move into the second tube body 8, one end of the pipe to be processed will abut against the limit baffle 12. The extrusion causes the limit baffle 12 to flip upward until it contacts the limit piece. At this time, the pipe to be processed stops moving, the cutting length is determined, and then the laser cutting machine 2 starts to cut the pipe. After the pipe to be processed is cut, the second pipe body 8 naturally flips downward, so that the slag in the processing process slides downward and is discharged. After the slag is discharged, the moving seat 4 drives the remaining part of the pipe to be processed to move. At this time, the pipe to be processed will squeeze the cut pipe. Since one end of the cut pipe is blocked by the limit baffle 12, the pipe to be processed squeezes the cut pipe and causes the second pipe body 8 to flip downward. Further flipping of the second pipe body 8 downward will cause one end of the slide bar 16 to be squeezed and contacted with the constraint block 15, causing the slide bar 16 to slide, thereby driving the rack 20 to move. Through the mutual engagement of the rack 20 and the gear 21, the limit piece flips over, releasing the constraint on the limit baffle 12. The limit baffle 12 can flip over to release the obstruction to the cut pipe, and then the cut pipe can be removed.

[0038] Furthermore, the supporting assembly includes a connecting sleeve 11 and a mounting rod 27. The connecting sleeve 11 is fixedly connected to the outer surface of the second tube body 8. Two slide plates 28 are slidably provided inside the connecting sleeve 11. The two slide plates 28 are connected on opposite sides by a connecting spring 29. One end of the mounting rod 27 is movably penetrated into the second tube body 8 and is rotatably embedded with a ball 26. The other end of the mounting rod 27 is fixedly connected to one of the slide plates 28. A second adjusting bolt 25 for squeezing the other slide plate 28 is threadedly penetrated at one end of the connecting sleeve 11. The pipe to be processed is supported by the supporting assembly so that there is a gap between the pipe to be processed and the inner wall of the second tube body 8 to facilitate the discharge of slag. By setting the second adjusting bolt 25, the elastic force of the connecting spring 29 can be adjusted to meet the support requirements for pipes of different models.

[0039] Furthermore, the limiting member includes a mounting block 22 rotatably arranged on the inner side of the support plate 14 and a first adjusting bolt 23 threadedly passing through the mounting block 22. A notch groove 24 for flipping the limiting baffle 12 is provided on the surface of the second tube body 8. The lower end surface of the first adjusting bolt 23 is in contact with the outer surface of the limiting baffle 12. The flipping degree of the limiting baffle 12 is adjusted by rotating the first adjusting bolt 23, thereby achieving the effect of adjusting the cutting length of the pipe fitting, ensuring that the cutting length of the pipe fitting to be processed is the same each time, and further improving the work efficiency.

[0040] Furthermore, a collection box 7 for collecting slag generated during the cutting process is provided at one end of the machine base 1. The second tube body 8 naturally flips downward, so that the slag generated during the cutting process slides downward and falls into the collection box 7, making it convenient for staff to collect and clean it up uniformly.

[0041] Furthermore, the first tube body 6 is fixedly connected to the upper end surface of the machine base 1 through the connecting base 9 .

[0042] Furthermore, there are two support plates 14 and they are symmetrically arranged. Both sides of the mounting block 22 are rotatably connected to the support plates 14 through rotating shafts. The rotating shafts are sleeved with gears 21. One side of the fixed plate 19 is provided with a rack 20 that meshes with the gear 21, which effectively ensures the installation strength of the mounting block 22. At the same time, the mutual cooperation between the two racks 20 and the two gears 21 ensures the stability of the rotation of the mounting block 22.

[0043] Furthermore, a three-jaw chuck for clamping the pipe is rotatably provided on one side of the movable seat 4. The three-jaw chuck can effectively clamp and fix the end of the pipe to be processed. A motor for driving the three-jaw chuck to rotate is provided inside the movable seat 4. The motor drives the three-jaw chuck to rotate, and then drives the pipe to be processed to rotate, thereby achieving the effect of circular cutting of the pipe to be processed. The laser cutting machine 2, the motor, and the driving machine 5 are electrically connected to the controller 3 respectively.

[0044] Furthermore, a vibration spring is provided at the upper end of the machine base 1 and cooperates with the lower surface of the second tube body 8. When the second tube body 8 naturally flips downward, it will squeeze the vibration spring. Under the action of the vibration spring, the second tube body 8 vibrates, thereby causing the slag in the second tube body 8 to fall quickly.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
