Description

Technical Field

[0001] The utility model relates to the technical field related to automobile manufacturing equipment, in particular to a device for extracting a bending plug core of an automobile bumper. Background Art

[0002] When the bumper beam is bent, due to the large deformation at the bend and the lack of support in the larger cavity, uncontrollable collapse will occur in the larger cavity on the inner arc surface. In order to reduce the number of collapses and reduce the depth of collapse, it is necessary to insert a joint plug into the cavity to provide support for the cavity during bending to reduce the number of collapses and reduce the depth of collapse. While the plug provides support for the cavity during bending, it will also be tightly pressed by the outer wall of the cavity.

[0032] Reference Figures 1 to 2 According to the first aspect of the present invention, a device for extracting a plug core from a bent automobile bumper comprises a machine base 100, a linear drive device 200, a limiting component 300 and a connecting block 400. The linear drive device 200 is arranged on the machine base 100, the limiting component 300 is arranged on the machine base 100, the limiting component 300 comprises a first limiting portion 310 and a second limiting portion 320, the first limiting portion 310 can abut against a part of the end of a workpiece 500, the second limiting portion 320 can abut against a side of the workpiece 500, the connecting block 400 is detachably connected to the linear drive device 200 in transmission, the connecting block 400 is provided with a connecting groove 410 which runs through from top to bottom, the connecting groove 410 can be used for the plug core 600 to be plugged in from top to bottom, the linear drive device 200 can drive the connecting block 400 to move forward and backward to drive the plug core 600 to be pulled out from the workpiece 500. The workpiece 500 with the plug core 600 can be inserted into the connecting block 400 from top to bottom through the connecting groove 410, which is convenient to operate. The connecting block 400 can be set to different specifications so that it can be detachably connected and replaced with the linear drive device 200 to adapt to different plug cores 600. The first limiting portion 310 can abut against the end of the workpiece 500, and the second limiting portion 320 can abut against the side of the workpiece 500 to position the workpiece 500. The workpiece 500 can be limited in both the end and side directions, so that when the linear drive device 200 drives the connecting block 400 to pull out the plug core 600, the shaking of the workpiece 500 can be reduced, thereby reducing the scratching of the inner wall of the cavity.

[0033] Specifically, the end of the bumper workpiece 500 has a core 600 that needs to be pulled out. The connecting groove 410 of the connecting block 400 can be set to match the shape of the core 600 and enable it to be inserted into the connecting block 400. Different cores 600 can be provided with corresponding connecting blocks 400. The connecting block 400 can be replaced on the linear driving device 200. The specific connection method is not limited herein. Before work, the connecting block 400 is driven by the linear driving device 200 to the extended state. When the workpiece 500 is installed, it can be positioned and limited by the limiting component 300. The first limiting portion 310 can abut against and limit the end of the workpiece 500, and the second limiting portion 320 can abut against and limit the side of the workpiece 500. The specific structures of the first limiting portion 310 and the second limiting portion 320 are not limited herein. After the workpiece 500 is installed, the linear driving device 200 drives the connecting block 400 to pull back. At this time, the limiting component 300 can stably support the workpiece 500 so that it will not shake or deflect, enabling the core 600 to be smoothly pulled out, thereby reducing the scratching of the inner wall of the cavity of the workpiece 500. It can be understood that the cores 600 at both ends of the workpiece 500 can be pulled out through the above structure, and only the direction of the workpiece 500 needs to be changed.

[0034] Referring to Figures 1 to 4 , according to some embodiments of the present invention, the first limiting portion 310 is located on one side of the core 600, and the second limiting portion 320 is located on the other side of the core 600. Specifically, a partial area of the core 600 is located at the end of the workpiece 500. The first limiting portion 310 abuts against the end area on one side of the core 600, and the other side abuts against and cooperates with the side of the workpiece 500 through the second limiting portion 320. The second limiting portion 320 restricts the deflection of the workpiece 500, so that it is not necessary to provide two limiting portions at the end, which is convenient for component arrangement and has a low manufacturing cost.

[0035] Referring to Figures 1 to 4 , according to some embodiments of the present invention, the limiting component 300 further includes a third limiting portion 330, and the third limiting portion 330 can abut against the bottom of the workpiece 500. Specifically, the third limiting portion 330 is located at the bottom of the workpiece 500, and the third limiting portion 330 can support the workpiece 500 to further stabilize the workpiece 500.

[0036] According to some embodiments of the present invention, the third limiting portion 330 and the second limiting portion 320 are of an integral structure. Specifically, the third limiting portion 330 and the second limiting portion 320 can be integrally formed by machining to improve the machining accuracy of the mating surface with the workpiece 500 and further stabilize the workpiece 500.

[0037] It can be understood that the workpiece 500 can be supported on three surfaces through the first limiting portion 310, the second limiting portion 320 and the third limiting portion 330, improving stability and also facilitating the placement of the workpiece 500 with a small assembly difficulty.

[0038] Reference Figures 1 to 4 According to some embodiments of the present invention, the third position limiting portion 330 has a guiding inclined surface 331, and the guiding inclined surface 331 is arranged to be inclined downward along the driving direction of the linear driving device 200. Specifically, the guiding inclined surface 331 matches the bending degree of the workpiece 500, can fit closely with the workpiece 500, and can guide the workpiece 500 to be positioned when the workpiece 500 is installed, so as to facilitate operation.

[0039] Reference Figures 1 to 5 According to some embodiments of the present invention, the connecting groove 410 includes a first groove body 411 and a connecting groove body 412. The connecting groove body 412 is disposed on a side of the first groove body 411 away from the linear drive device 200. The connecting groove body 412 penetrates the side wall of the connecting block 400, and the width of the first groove body 411 is greater than the width of the connecting groove body 412. Specifically, the first groove body 411 can be set to be wider, while the connecting groove body 412 is set to be narrower. The plug core 600 can extend into the first groove body 411 through the connecting groove body 412, and the wider side wall of the first groove body 411 can cooperate with the plug core 600 to make it move laterally. The cooperation structure is relatively simple, easy to manufacture, and low in cost.

[0040] It is understandable that the plug core 600 and the connecting piece may also be connected by fasteners.

[0041] Reference Figures 1 to 5 According to some embodiments of the present invention, the machine base 100 is provided with a sliding track 110, the sliding track 110 is extended along the driving direction of the linear drive device 200, and the connecting block 400 is slidably arranged on the sliding track 110. The stability of the core pulling can be improved, thereby further reducing the scratching of the cavity of the workpiece 500.

[0042] Specifically, the sliding rail 110 and the connecting block 400 are slidably matched, so that the connecting block 400 can only slide along the driving direction of the linear drive device 200, which can stabilize the movement trajectory of the connecting block 400 and further improve the stability of core pulling, thereby further reducing the scratches on the cavity of the workpiece 500.

[0043] Reference Figures 1 to 4 According to some embodiments of the present invention, the opening of the sliding rail 110 faces upward, and the connecting block 400 can be installed to the sliding rail 110 from the opening of the sliding rail 110. This makes it easy to disassemble and assemble the connecting block 400 and the sliding rail 110 and to maintain it.

[0044] According to some embodiments of the present utility model, the linear driving device 200 includes a cylinder 210, and the connecting block 400 is detachably connected to the output rod of the cylinder 210.
