Abstract
Description
Technical Field
[0001] This invention relates to the field of automotive door panel processing technology, specifically to a cutting fixture for automotive door panel processing and its usage method. Background Technology
[0002] As the automotive industry moves towards lightweighting, personalization, and intelligence, car door panels, as core interior components, are becoming increasingly complex in terms of materials (such as PP honeycomb panels, ABS composite panels, leather coverings, and carbon fiber composites) and structure. They must not only meet the requirements of aesthetics and precise assembly but also provide functions such as sound insulation, vibration damping, and safety protection. In the production process of car door panels, the cutting process is a critical step. Precise cutting of the door panel substrate and covering layers is necessary to create contours, mounting holes, and clearance grooves that conform to assembly dimensions, directly affecting subsequent assembly accuracy and the overall quality of the vehicle's interior.
[0003] In existing technologies, when laser cutting technology is used to process car door panels, corresponding scraps are generated. However, current cutting fixtures do not integrate effective scrap collection devices. The scraps generated during cutting (such as PP granules and carbon fiber fragments) are scattered on the production site, which not only pollutes the environment and increases cleaning costs, but also leads to the waste of recyclable materials.
[0004] Therefore, we propose a cutting fixture for automotive door panel processing and its usage method to solve the problems mentioned above. Summary of the Invention
[0005] The purpose of this invention is to provide a cutting fixture for automobile door panel processing and its usage method, so as to solve the problem that the current cutting fixtures mentioned in the background art do not integrate an effective scrap collection device, which increases the cleaning cost.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a cutting fixture for processing automobile door panels and its method of use, comprising a processing table and a cross slide table, wherein a laser cutting tool is provided at the bottom of the cross slide table, a discharge hole is provided at the top of the processing table, a first strip plate is fixedly installed on one side of the outer wall of the processing table, a concave seat is fixedly installed on the top of the first strip plate, two first support shafts are fixedly installed between the inner surface walls of the concave seat, rotating blocks are rotatably connected to the outer surface walls of the two first support shafts, and rotating blocks are fixedly installed on the top of the two rotating blocks. There are electric push rods, and connecting blocks are fixedly installed at the output ends of the two electric push rods. Two fixing blocks are fixedly installed at the bottom of the processing table. A fixing rod is fixedly installed between opposite sides of the outer walls of the two fixing blocks. A connecting column is movably sleeved on the outer wall of the fixing rod. An auxiliary unloading frame is fixedly installed on one side of the outer wall of the connecting column. Two concave blocks are fixedly installed at the bottom of the auxiliary unloading frame. A first connecting shaft is fixedly installed between the inner walls of the two concave blocks, and the inner walls of the two connecting blocks are rotatably connected to the outer walls of the two first connecting shafts.
[0007] Preferably, a fixed column is fixedly installed on the top of the processing table, and two tripods are fixedly installed on one side of the outer wall of the cross slide.
[0008] Preferably, a drive motor is fixedly mounted on the top of one of the tripods, and a bidirectional lead screw is fixedly mounted on one side of the outer wall of the drive motor. Two moving blocks are threadedly connected to the outer wall of the bidirectional lead screw.
[0009] Preferably, two second strip plates are fixedly installed on the outer wall of the fixed column. Each of the two second strip plates has a limiting groove at its bottom. Each of the two limiting grooves has a limiting slider movably embedded in its inner wall. The bottom of each limiting slider is fixedly connected to the top of the two moving blocks.
[0010] Preferably, a second support shaft is fixedly installed on the inner surface of each of the two movable blocks, and a Z-shaped connecting rod is rotatably connected to the outer surface of each of the two second support shafts.
[0011] Preferably, four guide rods are fixedly installed on the top of the processing table, and connecting plates are movably sleeved on the outer walls of the four guide rods. Two limiting plates are fixedly installed between one side of the outer walls of the four connecting plates.
[0012] Preferably, a grooved block is fixedly installed on the top of each of the two limiting plates, a second connecting shaft is fixedly installed on the inner surface of each of the two grooved blocks, and the inner surface of each of the two Z-shaped connecting rods is rotatably connected to the outer surface of the two second connecting shafts.
[0013] Preferably, limit rings are fixedly installed on the outer walls of all four guide rods, and a rectangular column is fixedly installed on the top of another tripod, with the outer wall of the bidirectional lead screw movably inserted into the interior of the rectangular column.
[0014] Preferably, a controller is fixedly installed on the top of the processing table, and two plate strips are fixedly installed on the top of the processing table.
[0015] A method for using a cutting fixture in automotive door panel processing includes the following steps: S1. First, place the car door panel to be processed on two strips. Then, start the drive motor through the controller. Under the action of the rectangular column, two second strips, two limit grooves and two limit sliders, it drives the two moving blocks to move towards each other on the double-acting screw. S2. Since both Z-shaped connecting rods rotate on the two second support shafts and the two second connecting shafts, and under the action of the four guide rods, the four connecting plates and the four limiting rings, the two connecting plates and the two limiting plates can move downward while the two moving blocks move towards each other, and limit the car door panel. S3. Next, the car door panel can be cut by the cross slide and laser cutting tool. Finally, the controller simultaneously starts two electric push rods. Under the action of the concave seat, two first support shafts, two rotating blocks, two connecting blocks, two first connecting shafts, two fixed blocks and fixed rods and connecting columns, the two rotating blocks can be driven to rotate on the two first support shafts and the two connecting blocks can be driven to rotate on the two first connecting shafts. This allows the connecting column and the auxiliary unloading frame to rotate along the fixed rod and complete the unloading.
[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. After the car door panel is cut using a cross slide and laser cutting tool, the resulting scraps will fall into the auxiliary unloading frame. Then, the controller simultaneously activates two electric push rods, which drive two rotating blocks to rotate on two first support shafts, and two connecting blocks to rotate on two first connecting shafts. Then, under the action of two fixed blocks, fixed rods, and connecting columns, the auxiliary unloading frame and connecting columns are driven to rotate on the fixed rods, and the auxiliary unloading frame slowly tilts downwards, preventing the scraps from scattering around or suddenly hitting the ground. This completes the collection of the laser-cut scraps while ensuring their integrity, reducing material waste, and thus improving the practicality of the cutting fixture.
[0017] 2. After the car door panel is placed in the appropriate position on the two mounting strips, the drive motor is started by the controller, which drives the bidirectional lead screw to rotate inside the rectangular column. Under the action of the two second strip plates, two limiting grooves and two limiting sliders, it drives the two moving blocks to move towards each other along the bidirectional lead screw. Since the two Z-shaped connecting rods rotate on the second connecting shafts in the two second support shafts and the two groove blocks, and under the action of the four guide rods and four connecting plates, the two limiting plates can be driven to move downward stably, thus limiting the car door panel. Then, the cross slide table and laser cutting tool are used to perform laser cutting, which improves the use effect of the car door panel processing and cutting fixture. Attached Figure Description

The inner surface of each of the two Z-shaped connecting rods 26 is rotatably connected to the outer surface of each of the two second connecting shafts 31. Since both ends of each of the two Z-shaped connecting rods 26 are rotatably connected to the two second support shafts 25 and the two second connecting shafts 31, and under the action of the four guide rods 27 and the four connecting plates 28, the two limiting plates 29 can be driven to move downward stably and limit the car door panel on the two release strips 35.
[0028] like Figure 1 , Figure 2 and Figures 5-8 As shown, limit rings 32 are fixedly installed on the outer walls of the four guide rods 27. A rectangular column 33 is fixedly installed on the top of another tripod 18, and the outer wall of the bidirectional lead screw 20 is movably inserted into the inside of the rectangular column 33. Through the action of the four limit rings 32, the four connecting plates 28 can be prevented from detaching from the four guide rods 27.
[0029] like Figures 1-4 and Figure 7 As shown, a controller 34 is fixedly installed on the top of the processing table 1, and two plate strips 35 are fixedly installed on the top of the processing table 1. The controller 34 starts the two electric push rods 9 and the drive motor 19 and controls the laser cutting tool 3, which has automation.
[0030] The usage and working principle of this device are as follows: First, place the car door panel to be laser-cut on two mounting strips 35. Then, start the drive motor 19 mounted on one of the tripods 18 via the controller 34. This drive motor 19 has a self-locking function, causing it to drive the bidirectional lead screw 20 to rotate inside the rectangular column 33. Since second strip plates 22 are installed on both sides of the fixed column 17, and limit grooves 23 are opened at the bottom of the two second strip plates 22, and the limit sliders 24 installed on the top of the two moving blocks 21 are movably embedded inside the two limit grooves 23, the two moving blocks 21 can be stably mounted on the bidirectional lead screw. The two Z-shaped connecting rods 26 move towards each other, and because their ends are rotatably connected to the second support shafts 25 in the two moving blocks 21 and the second connecting shafts 31 in the two slotted blocks 30, and the two slotted blocks 30 are both mounted on the top of the two limiting plates 29, and then guide rods 27 are installed on the top of the processing table 1 near the four corners, and connecting plates 28 are movably sleeved on the four guide rods 27, and one side of the outer wall of the four connecting plates 28 is fixedly connected to the two sides of the two limiting plates 29, so that when the two moving blocks 21 move towards each other, the two Z-shaped connecting rods 26 can be driven to move on the two second support shafts 25 and the two second connecting shafts 31 in the two slotted blocks 20. The two connecting shafts 31 rotate, simultaneously driving the two limiting plates 29 to move stably downwards, thus limiting the car door panel to be laser-cut on the two release strips 35. Then, the controller 34 controls the laser cutting tool 3 to move along the cross slide 2, thus performing laser cutting on the original cutting path of the car door panel. The scrap material after laser cutting will fall into the auxiliary unloading frame 14 along the discharge hole 4. At this time, the controller 34 simultaneously activates the two electric push rods 9 installed on the rotating block 8, causing the two connecting blocks 10 to rotate on the first connecting shaft 16 within the two concave blocks 15. And because the auxiliary unloading frame 1 4. The connecting column 13 installed on one side of the outer wall is movably sleeved on the fixed rod 12. Thus, by extending and retracting the two electric push rods 9, the auxiliary unloading frame 14 and the connecting column 13 can be driven to rotate downward on the fixed rod 12, and the auxiliary unloading frame 14 can be slowly tilted. This allows the scrap material to slowly move downward along the auxiliary unloading frame 14 and fall into the collection frame, without scattering around or suddenly hitting the ground. This completes the collection of the laser-cut scrap material, while also ensuring the integrity of the scrap material, reducing material waste, and improving the practicality of the cutting fixture. This improves the usage effect of the automotive door panel processing cutting fixture.
