Abstract

This application relates to the field of automotive crossbeam processing technology, and discloses an automotive crossbeam punching device, including a support frame, a linear slide, a first moving plate, a hydraulic cylinder, a second moving plate, a punch, a lateral limiting component, and a vertical limiting component. In use, after placing the automotive crossbeam on the base plate, the lateral and vertical limiting components can limit and fix the crossbeam in the lateral and vertical directions. Then, controlling the hydraulic cylinder drives the second moving plate to move up and down, ultimately driving the punch to move up and down, completing the punching operation. Furthermore, controlling the linear slide drives the first moving plate to move laterally, which in turn drives the hydraulic cylinder to move laterally, ultimately driving the punch to move laterally. Therefore, the lateral position of the punch can be adjusted, thereby changing the punching position. This allows multiple holes to be punched into the automotive crossbeam in a single clamping.

Technical Field

[0001] This application relates to the field of automotive crossbeam processing technology, and in particular to an automotive crossbeam punching device. Background Technology

[0002] A related technology (publication number: CN220837506U) discloses a punching device for automotive crossbeams, including a worktable and a support plate. The worktable has a horizontal section, and four guide members are fixedly connected to both ends of the horizontal section. A hydraulic cylinder is fixedly installed through the middle of the support plate, and a punch is fixedly installed on the lower surface of the hydraulic cylinder. Connecting blocks are fixedly installed at both ends of the bottom of the support plate, and connecting rods are fixedly connected to the middle of the two connecting blocks.

[0003] In the process of implementing the technical solution disclosed herein, it was found that the above technical solution has at least the following problems:

[0004] This automotive crossbeam punching device uses a hydraulic cylinder to drive a punch that moves up and down, punching holes in the clamped and fixed automotive crossbeam.

[0018] The present technical solution provides a punching device for automobile crossbeams, which can achieve the following technical effects:

[0019] This disclosure provides a punching device for an automotive crossbeam, comprising a support frame, a linear slide, a first moving plate, a hydraulic cylinder, a second moving plate, a punch, a lateral limiting component, and a vertical limiting component. The support frame includes a bottom plate and a top plate. Along the height direction of the support frame, the top plate is located above the bottom plate, and both the bottom and top plates support and install relevant components of the device. The bottom plate includes a strip-shaped hole along the length direction of the support frame for the punch to pass through. The linear slide is mounted on the top plate along the length direction of the support frame, providing driving force to achieve movement along the length direction of the support frame. The first moving plate is mounted on the moving end of the linear slide and moves along the length direction of the support frame under the drive of the linear slide. The hydraulic cylinder is mounted on the first moving plate along the height direction of the support frame, with its moving end facing the bottom plate, providing driving force to achieve movement along the height direction of the support frame. The second moving plate is mounted on the moving end of the hydraulic cylinder and moves along the height direction of the support frame under the drive of the hydraulic cylinder. The punch is mounted on the bottom surface of the second movable plate along the height direction of the support frame, and is used to abut against the vehicle crossbeam. Lateral limiting members are mounted on the top surface of the base plate, along the width direction of the support frame, located on both sides of the slotted hole, and are used to limit the vehicle crossbeam in the lateral direction. Vertical limiting members are mounted on the top surface of the base plate, along the length direction of the support frame, located on both sides of the slotted hole, and are used to limit the vehicle crossbeam in the vertical direction. Driven by a hydraulic cylinder, the punch can move into the interior of the slotted hole.

[0020] In use, after placing the car crossbeam on the base plate, the crossbeam is fixed in both the lateral and vertical directions by the lateral and vertical limiting components. Then, controlling the hydraulic cylinder drives the second moving plate to move up and down, ultimately driving the punch to move up and down to complete the punching operation. Furthermore, controlling the linear slide table drives the first moving plate to move laterally, which in turn drives the hydraulic cylinder to move laterally, ultimately driving the punch to move laterally. Therefore, the lateral position of the punch can be adjusted to change the punching position. This allows multiple holes to be punched in a single clamping of the car crossbeam.

[0038] Combination Figures 1 to 5As shown, this embodiment of the present disclosure provides a punching device for an automotive crossbeam, including a support frame 10, a linear slide 20, a first moving plate 30, a hydraulic cylinder 40, a second moving plate 50, a punch 60, a lateral limiting member 70, and a vertical limiting member 80. The support frame 10 includes a base plate 11 and a top plate 12. Along the height direction of the support frame 10, the top plate 12 is located above the base plate 11, and the top plate 12 and the bottom plate 11 are respectively used to support related components of the mounting device. The base plate 11 includes a strip-shaped hole opened along the length direction of the support frame 10, the strip-shaped hole for the punch 60 to pass through. The linear slide 20 is mounted on the top plate 12 along the length direction of the support frame 10, and is used to provide driving force to achieve the function of moving along the length direction of the support frame 10. The first moving plate 30 is mounted on the moving end of the linear slide 20, and moves along the length direction of the support frame 10 under the drive of the linear slide 20. A hydraulic cylinder 40 is mounted on the first movable plate 30 along the height direction of the support frame 10, with its moving end facing the base plate 11. It provides driving force to enable movement along the height direction of the support frame 10. A second movable plate 50 is mounted on the moving end of the hydraulic cylinder 40 and moves along the height direction of the support frame 10 under the drive of the hydraulic cylinder 40. A punch 60 is mounted on the bottom surface of the second movable plate 50 along the height direction of the support frame 10, and abuts against the vehicle crossbeam. A lateral limiting member 70 is mounted on the top surface of the base plate 11, along the width direction of the support frame 10, located on both sides of the slotted hole, and limits the vehicle crossbeam in the lateral direction. A vertical limiting member 80 is mounted on the top surface of the base plate 11, along the length direction of the support frame 10, located on both sides of the slotted hole, and limits the vehicle crossbeam in the vertical direction. Under the drive of the hydraulic cylinder 40, the punch 60 can move into the interior of the slotted hole.

[0039] This disclosure provides a punching device for automotive crossbeams. After placing the automotive crossbeam on a base plate 11, the crossbeam is fixed in both the lateral and vertical directions by lateral limiting members 70 and vertical limiting members 80. Then, controlling the hydraulic cylinder 40 causes the second moving plate 50 to move up and down, ultimately causing the punch 60 to move up and down, completing the punching operation. Furthermore, controlling the linear slide 20 causes the first moving plate 30 to move laterally, which in turn causes the hydraulic cylinder 40 to move laterally, ultimately causing the punch 60 to move laterally. Therefore, the lateral position of the punch 60 can be adjusted, thereby changing the punching position. This allows multiple holes to be punched into the automotive crossbeam in a single clamping operation.

[0040] Optionally, combined Figure 1 , Figure 3 and Figure 5 As shown, the support frame 10 also includes a support rod 13. The support rod 13 is installed between the base plate 11 and the top plate 12 along the height direction of the support frame 10.

[0041] In this embodiment of the disclosure, the support rod 13 is used to determine the relative position of the bottom plate 11 and the top plate 12.

[0042] Optionally, combined Figure 3 and Figure 4 As shown, the lateral limiting member 70 includes a support plate 71, a first cylinder 72, and a first clamping plate 73. The support plate 71 is mounted on the top surface of the base plate 11, along the width direction of the support frame 10, located on both sides of the strip-shaped hole, and is used to support and mount the first cylinder 72. The first cylinder 72 is mounted on both sides of the support plate 71 along the width direction of the support frame 10, with the moving ends of the two first cylinders 72 being relatively distributed and used to provide driving force. The first clamping plates 73 are respectively mounted on the moving ends of the two first cylinders 72 and move under the drive of the two first cylinders 72.

[0043] In this embodiment, controlling the operation of the two first cylinders 72 can drive the two first clamping plates 73 to move towards or away from each other. When the two first clamping plates 73 move towards each other, they can clamp the car crossbeam placed on the base plate 11. When the two first clamping plates 73 move in opposite directions, sufficient placement area is provided so that the car crossbeam can be placed on the base plate 11.

[0044] Optionally, combined Figure 3 and Figure 4 As shown, the lateral limiting member 70 also includes a first buffer block 74. The first buffer block 74 is respectively installed on the opposite sides of the first clamping plates 73 on both sides.

[0045] In this embodiment of the present disclosure, the first buffer blocks 74 on both sides are used to buffer the impact on the surface of the vehicle crossbeam.

[0046] Optionally, combined Figure 3 and Figure 4 As shown, the lateral limiting member 70 also includes a first optical axis 75. The first optical axis 75 is slidably inserted through the two side support plates 71 along the width direction of the support frame 10, and is connected to the two side first clamping plates 73 respectively.

[0047] In this embodiment, the first optical axes 75 on both sides serve as guide supports to improve the stability of the first clamping plates 73 on both sides when they move and reduce the radial force on the moving ends of the first cylinders 72 on both sides.

[0048] Optionally, combined Figure 3 and Figure 4 As shown, the lateral limiting member 70 also includes a first linear bearing. The first linear bearing is respectively fitted onto the first optical shafts 75 on both sides and is respectively mounted on the support plates 71 on both sides.

[0049] In this embodiment, the first linear bearings on both sides are used to reduce the friction between the first optical shafts 75 on both sides and the support plates 71 on both sides, and to improve the accuracy of the first optical shafts 75 on both sides sliding relative to the support plates 71 on both sides.

[0050] Optionally, combined Figures 1 to 5 As shown, the vertical limiting member 80 includes an elbow clamp 81, a second clamping plate 82, and a second cylinder 83. The elbow clamp 81 is mounted on the top surface of the base plate 11, along the length of the support frame 10, located on both sides of the strip hole, and is used to clamp the automobile crossbeam placed on the base plate 11. The second clamping plate 82 is respectively mounted on the clamping ends of the elbow clamps 81 on both sides, and moves under the drive of the clamping ends of the elbow clamps 81 on both sides. The second cylinder 83 is mounted on the top surface of the base plate 11 along the height direction of the support frame 10, and is located on both sides of the strip hole along the length direction of the support frame 10, and is used to provide driving force. The driving ends of the elbow clamps 81 on both sides are rotatably mounted on the moving ends of the second cylinders 83 on both sides, and move under the drive of the moving ends of the second cylinders 83 on both sides.

[0051] In this embodiment, controlling the operation of the second cylinders 83 on both sides can drive the drive ends of the elbow clamps 81 on both sides to rotate. Then, the clamping ends of the elbow clamps 81 on both sides can rotate in the opposite direction, thereby driving the second clamping plates 82 on both sides to press or loosen the automobile crossbeam placed on the base plate 11.

[0052] Optionally, combined Figures 1 to 5 As shown, the vertical limiting member 80 also includes a second buffer block 84. The second buffer block 84 is respectively installed on the second clamping plates 82 on both sides.

[0053] In this embodiment, the second buffer blocks 84 on both sides are used to buffer the impact on the surface of the vehicle crossbeam.
