Description
Technical Field
[0001] This invention relates to the field of vehicle frame installation, and more specifically, to an integrated device and method for laser cutting and hydraulic punching of vehicle frames. Background Technology
[0002] In the process of producing chassis for multiple vehicle models on the same production line, the positions and shapes of the body mounting holes, cargo box positioning holes, lower control arm front and rear mounting holes, and leaf spring front and rear seat mounting holes are different for each model. These parts need to be positioned by switching positioning units on the welding fixture. Due to the complex structure of the fixture and the difficulty of adjustment, after welding, thermal stress and cooling shrinkage cause the overall chassis to deform, affecting the accuracy of the hole positions.
[0003] In existing technologies, mounting holes for the body, cargo box, lower control arms (front and rear), and leaf springs (front and rear seat) are all pre-drilled on their respective parts. Positioning and clamping units are then designed using these holes in the welding fixture to weld the parts to the chassis. When multiple vehicle models are produced on the same line, the positions of these parts differ, requiring multiple sets of positioning and clamping units, or switching unit positions, resulting in a highly complex fixture mechanical structure. Existing technologies are not flexible enough for position adjustments, making adjustments difficult and sometimes necessitating the development of new fixtures to meet the needs of more vehicle models. Summary of the Invention
[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide an integrated equipment and method for laser cutting and hydraulic punching of vehicle frames. Based on the layout of key mounting holes in the vehicle frame, a seven-axis robotic laser cutter is used on both sides of the frame to ensure flexible production and positional accuracy of all body mounting holes and cargo box positioning holes. At the bottom of the frame, a Z-axis lifting platform and X, Y displacement slides drive a hydraulic punching module to ensure flexible production and positional accuracy of the front and rear mounting holes for the lower control arms and the front and rear seat mounting holes for the leaf springs.
[0005] To achieve the above-mentioned technical effects, the present invention adopts the following technical solution:

The several hydraulic punching modules are respectively set on the Z-axis lifting mechanism and the X,Y displacement slides of the hydraulic punching module. The movement of the Z-axis lifting mechanism in the Z direction enables the hydraulic punching module to punch the mounting holes at different heights. The movement of the X,Y displacement slides of the hydraulic punching module enables the punching of mounting holes of components at different positions.
[0009] When the chassis is placed in the preset position in the integrated equipment, a laser cutting seven-axis robot cuts the body mounting holes on the left and right sides of the chassis and the cargo box positioning holes. After the cutting is completed, several hydraulic punching modules punch the mounting holes in the preset positions to complete the forward punching and reverse punching.

The punch seat and the punch are located on the punch seat linear slide rail, and the punch is located on the punch seat. The punch seat linear slide rail is used to support the precise movement and positioning of other components of the punch unit during the punching process. The punch seat is used to fix the punch for punching operations. The punch is used to cooperate with the die unit to perform punching operations.
[0016] Preferably, the die unit includes a die and a die holder, wherein the die cooperates with the punch to perform a punching operation and discharges the waste material into the die holder.
[0017] According to a second aspect of the present invention, a method for laser-cutting and hydraulically punching holes in a vehicle frame is provided, which employs the aforementioned integrated equipment for laser-cutting and hydraulically punching holes in a vehicle frame, specifically including the following steps:
[0018] Step S1: The integrated laser cutting and hydraulic punching equipment for the vehicle frame causes the X-axis slide switching mechanism and the hydraulic punching module X, Y displacement slide to move to the position of the vehicle model being called.
[0019] Step S2: The chassis is moved above this integrated equipment, placed on the Z-axis lifting mechanism, and transported to the working height;

[0040] Example 1
[0041] like Figure 1 As shown, this embodiment provides an integrated machine for laser cutting and hydraulic punching of vehicle frames. The machine utilizes a seven-axis robotic laser cutter on both sides of the vehicle frame according to the layout of key mounting holes, ensuring flexible production and positional accuracy of all body mounting holes and cargo box positioning holes. At the bottom of the vehicle frame, a Z-axis lifting platform and X, Y displacement slides drive a hydraulic punching module, ensuring flexible production and positional accuracy of the front and rear mounting holes for the lower control arms and the front and rear seat mounting holes for the leaf springs.
[0042] The integrated equipment consists of a waste conveyor belt 002, a moving module, a fixed module, and an opening module. The moving module includes a robot displacement slide rail, an X-axis slide switching mechanism 004, four Z-axis lifting mechanisms 007, and a hydraulic punching module with X and Y displacement slides 008. The opening module includes a laser-cutting seven-axis robot 003 and ten hydraulic punching modules 006. The fixed module consists of seven chassis clamping mechanisms 005. The laser-cutting seven-axis robot 003 is located on the robot displacement slide rails on both outermost sides of the equipment. Its movement along these slide rails cuts the mounting holes on the left and right sides of the chassis and the cargo box positioning holes. The 10 sets of hydraulic punching modules 006 are respectively installed on the Z-axis lifting mechanism 007 and the hydraulic punching module X,Y displacement slide 008. The hydraulic punching module 006 punches the mounting holes at different heights by moving the Z-axis lifting mechanism 007 in the Z direction, and punches the mounting holes of components at different positions by moving the hydraulic punching module X,Y displacement slide 008.
[0043] Before drilling holes in the integrated equipment described in this invention, the corresponding vehicle model program is first called via PLC model transmission, causing the mobile module to move to the position of the called vehicle model. Then, the vehicle frame to be drilled is transported to the top of this equipment using a lifting device and placed on the Z-axis lifting mechanism 007, which drives it to the working height. Next, the vehicle frame clamping mechanism 005 clamps the vehicle frame workpiece to prevent movement during laser cutting or hydraulic punching. Then, the formal vehicle frame drilling stage begins. First, the laser cutting seven-axis robot 003 calls the corresponding vehicle model program to cut the mounting holes on the left and right sides of the vehicle frame and the cargo box positioning holes. After cutting, the laser cutting seven-axis robot 003 returns to the zero position, and the hydraulic punching module 006 begins operation. First, the hydraulic cylinder pushes forward to punch the front and rear mounting holes of the lower swing arm and the front and rear seat mounting holes of the leaf spring, completing the forward punch. Then, the hydraulic cylinder pulls back to punch the mounting holes on the reverse side of the front and rear mounting holes of the lower swing arm and the front and rear seat mounting holes of the leaf spring, completing the reverse punch. After punching on both sides, the hydraulic cylinder returns to the middle position. Finally, the waste generated from laser cutting and hydraulic punching is discharged via waste conveyor belt 002.
[0044] like Figure 4 As shown, the Z-axis lifting mechanism 007 includes a base 7-01, a Z-axis drive servo motor 7-02, a ball screw system a7-03, a Z-axis linear guide rail 7-04, a Z-axis movable support for the frame 7-05, and a pneumatic pin seat 7-06. The base 7-01 is the fundamental support of the entire mechanism, providing overall stability and support. The Z-axis drive servo motor 7-02 is mounted on the base and provides power drive in the Z direction (vertical direction). The ball screw system a7-03 is connected to the Z-axis drive servo motor 7-02, and the Z-axis servo motor 7-02 transmits power and motion control through the ball screw system a7-03. The Z-axis linear guide rail 7-04 is fixed to the base 7-01, providing guidance and support for the Z-axis movable support for the frame 7-05. The Z-axis movable support 7-05 of the frame is located above the ball screw system a7-03 and on the Z-axis linear slide rail 7-04. Its Z-axis movement on the Z-axis linear slide rail 7-04 is achieved through the movement of the ball screw system a7-03. A pneumatic pin seat 7-06 is mounted above the Z-axis movable support 7-05 of the frame and can move with the frame, used for clamping or releasing operations at specific positions.
[0045] Through the structural relationship of the above components, the Z-axis drive servo motor 7-02 can drive the ball screw system a7-03, thereby driving the frame Z-axis movable support 7-05 and the pneumatic pin seat 7-06 to move and position precisely in the Z direction under the guidance of the Z-axis linear slide rail 7-04.
[0046] like Figure 2 As shown, the X-axis slide switching mechanism 004 includes the following components: an X-axis drive servo motor 4-01, a hydraulic punching module switching slide 4-02, a ball screw system, a frame clamping mechanism switching slide 4-04, and an X-axis linear slide rail 4-05. The X-axis drive servo motor 4-01 is mounted on the system base and provides power drive in the X direction (horizontal direction). The ball screw system is connected to the X-axis drive servo motor 4-01. The X-axis linear slide rail 4-05 is equipped with the hydraulic punching module switching slide 4-02 and the frame clamping mechanism switching slide 4-04, and both slides are connected to the ball screw system.
[0047] Based on the structural relationship of the above components, the X-direction drive servo motor 4-01 drives the ball screw system, which in turn drives the hydraulic punching module switching slide 4-02 or the frame clamping mechanism switching slide 4-04 to move and position precisely in the X direction under the guidance of the X-direction linear slide rail 4-05.
[0048] like Figure 3As shown, the hydraulic punching module X,Y displacement slide 008 includes an X-axis displacement motor 8-01, a hydraulic punching module switching slide 8-02, a ball screw system, a hydraulic punching module X-axis linear slide rail 8-04, a Y-axis displacement motor 8-05, a ball screw system b8-07, and a hydraulic punching module Y-axis linear slide rail 8-08. The X-axis displacement motor 8-01 is connected to the ball screw system and drives the hydraulic punching module switching slide 8-02 above it, allowing it to move and position in the X direction under the guidance of the hydraulic punching module X-axis linear slide rail 8-04. The Y-axis displacement motor 8-05 is connected to the ball screw system b8-07 and drives the hydraulic punching module switching slide 8-02 above it to move and position in the Y direction under the guidance of the hydraulic punching module Y-axis linear slide rail 8-08.
[0049] Before drilling holes in the chassis, the X-axis slide switching mechanism 004, the four Z-axis lifting mechanisms 007, and the X and Y displacement slides 008 of the hydraulic punching module in the moving module move to preset positions according to the appearance of different vehicle models before production, ensuring that the chassis can be placed in the preset position when it enters the equipment. After the chassis workpiece enters the preset position in the equipment, it is fixed by the fixing module.
[0050] like Figure 5 As shown, the fixing module is a frame clamping mechanism 005. The frame clamping mechanism 005 includes, from bottom to top, a clamping mechanism base 5-01, a high-pressure clamping cylinder 5-02, and a pressure block 5-03. The pressure block 5-03 is connected to the high-pressure clamping cylinder 5-02. Under the action of the high-pressure clamping cylinder 5-02, the pressure block 5-03 can clamp the workpiece to prevent the workpiece from moving during laser cutting or hydraulic punching.
[0051] After the chassis is fixed, the laser-cutting seven-axis robot 003 calls the corresponding vehicle model program to cut the mounting holes on both sides of the chassis and the positioning holes in the cargo box. After cutting, the robot returns to the zero position, and the hydraulic punching module 006 begins to work.
[0052] like Figure 6 As shown, the hydraulic punching module 006 includes the following components: punching module base 6-01, adjusting shim 6-02, floating base 6-03, nitrogen cylinder 6-04, zeroing pin seat 6-05, floating linear slide rail 6-06, hydraulic cylinder seat 6-07, punch seat linear slide rail 6-08, punch seat guide plate 6-09, punch seat 6-10, die 6-11, scrap trough 6-12, die seat 6-13, punch 6-14, unloading plate assembly 6-15, hydraulic cylinder 6-16, sensing block bracket 6-17, and displacement sensor 6-18.
[0053] Hydraulic cylinder 6-16 is fixed on hydraulic cylinder seat 6-07 and can drive the punch unit to push forward or pull backward. The specific stroke of the push or pull is controlled by displacement sensor 6-18 set on induction block bracket 6-17. The punch unit includes: punch seat linear slide rail 6-08, which supports other punch units to ensure their precise movement and positioning during punching; punch seat guide plate 6-09, which guides and stabilizes the movement path of punch seat 6-10; punch seat 6-10, which fixes punch 6-14 for punching; punch 6-14, which cooperates with die 6-11 for punching. The punch seat 6-10 and punch 6-14 are located on punch seat linear slide rail 6-08, and the punch is located on punch seat 6-10. The die unit includes a die 6-11 and a die base 6-13. The die 6-11 cooperates with the punch 6-14 to perform punching operations and discharges waste material into the die base 6-13.
[0054] During the punching process, hydraulic cylinder 6-16 drives the linear slide rail 6-08 of the punch seat to move, which in turn drives the punch seat guide plate 6-09, punch seat 6-10, punch 6-14, and stripper plate assembly 6-15 to perform the punching operation. First, through the cooperation of punch 6-14 and die 6-11, the punch pushes forward to punch the front and rear mounting holes of the lower swing arm and the front and rear seat mounting holes of the leaf spring, completing the forward punch. Then, hydraulic cylinder 6-16 pulls back to punch the mounting holes on the opposite side of the front and rear mounting holes of the lower swing arm and the front and rear seat mounting holes of the leaf spring, completing the reverse punch. After punching on both sides, hydraulic cylinder 6-16 returns to the middle position. During the punching process, displacement sensor 6-18 monitors and controls the position of punch 6-14 to ensure the accuracy and reliability of each punching operation. This equipment utilizes a Z-axis lifting mechanism 007 and a hydraulic punching module X, Y displacement slide 008 at the bottom of the frame to drive the hydraulic punching module 006 to move in the XYZ direction, ensuring flexible production and positional accuracy of the front and rear mounting holes of the lower control arm and the front and rear seat mounting holes of the leaf spring.
[0055] Finally, the waste generated from laser cutting and hydraulic punching is discharged via waste conveyor belt 002.
[0056] Example 2
[0057] This embodiment provides a method for laser-cutting and hydraulically punching holes in a vehicle frame, implemented using the integrated equipment for laser-cutting and hydraulically punching holes in the vehicle frame described in the first embodiment. The method provided in this embodiment, which performs the punching and cutting processes after the vehicle frame welding is completed, can reduce hole position changes caused by welding deformation. Specifically, it includes the following steps:
[0058] Step S1: The integrated laser cutting and hydraulic punching equipment for the vehicle frame calls the corresponding vehicle program through the PLC vehicle model transmission, so that the X-axis slide switching mechanism 004 and the X,Y displacement slide 008 of the hydraulic punching module move to the position of the called vehicle model.
[0059] Step S2: The chassis is transported from the previous station to the top of this integrated equipment by an automatic lifting device and placed on the Z-axis lifting mechanism 007, which is driven by a servo motor to move to the working height.
[0060] Step S3: The laser cutting seven-axis robot 003 calls the corresponding vehicle model program to cut the body mounting holes on the left and right sides of the frame and the cargo box positioning holes. After the cutting is completed, the robot returns to the zero position.
[0061] Step S4: The hydraulic cylinder 6-16 of the hydraulic punching module 006 pushes forward to punch the mounting holes on the front and rear sides of the lower control arm and the front and rear seat mounting holes of the leaf spring, completing the forward punch. Then, the hydraulic cylinder pulls back to punch the mounting holes on the reverse side of the lower control arm and the front and rear seat mounting holes of the leaf spring, completing the reverse punch. After punching on both sides, the hydraulic cylinder returns to the middle position.
[0062] Step S5: Waste generated from laser cutting and hydraulic punching is discharged via waste conveyor belt 002.
[0063] The specific embodiments of the present invention have been described above. Based on the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of the present invention.
