Description

Technical Field

[0001] This application relates to the technical field of automotive parts processing, and more specifically, to an apparatus for punching holes in automotive bumpers. Background Technology

[0002] Car bumpers are an important component of automobiles, serving multiple purposes including safety protection, vehicle aesthetics, and improving aerodynamics. From a safety perspective, they act as a buffer in low-speed collisions, protecting the front and rear of the vehicle; they also offer some protection to pedestrians in accidents. Aesthetically, they are decorative, becoming an important part of a car's exterior design; additionally, they contribute to aerodynamics. Currently, the manufacturing process of bumpers involves punching holes to allow for the installation of car radar sensors.

[0003] Currently, the mainstream punching equipment cannot guarantee the accuracy of the punching position. Different bumpers have different punching positions, making it even more difficult to guarantee the hole position. Different tooling needs to be customized for different bumper models, which is costly, inconvenient to operate, and has low drilling efficiency. Utility Model Content

[0004] To address the low drilling efficiency of punching devices, this application provides a punching device for automobile bumpers.

[0005] A punching device for automotive bumpers includes a box body, a fixing component located above the box body, a column slidably connected to the back of the box body, a first driving component for driving the column to slide, and a hydraulic cylinder fixed to the column. The hydraulic cylinder is located above the box body, and a punching head is detachably mounted on the end of the cylinder rod, with the cylinder rod facing the bumper. The first driving component includes a first screw rotatably connected to the box body, a guide rod fixedly connected to the box body, and a first motor fixedly connected to the box body. The output shaft of the first motor is fixedly connected to the first screw, and the column is threadedly connected to the first screw and slidably connected to the guide rod.

[0006] By adopting the above technical solution, the bumper is fixed to the fixing component of the box body, and the driving component drives the hydraulic cylinder to slide into place before drilling holes in the bumper, which meets the drilling requirements of different hole positions and improves work efficiency.

[0007] Preferably, the fixing component includes a fixing plate fixedly connected to the top of the box body and a sliding plate slidably connected to the box body. A movable rod is provided on the side of the sliding plate away from the fixing plate. A spring is sleeved on the movable rod. The two ends of the spring abut against the box body and the sliding plate respectively, for driving the sliding plate to slide, so that the bumper is clamped between the sliding plate and the fixing plate.

[0008] By adopting the above technical solution, the positioning accuracy before drilling is improved by clamping and fixing the bumper with the sliding plate and the fixing plate, and the time for clamping and disassembling the bumper is reduced, thereby improving the drilling efficiency.

[0009] Preferably, the column includes an upright column slidably connected to the main body of the box, a horizontal column rotatably connected to one side of the upright column, and a sliding seat slidably connected to the horizontal column. A hydraulic cylinder is fixedly connected to the sliding seat, and a second motor for driving the horizontal column to rotate is fixedly connected to the upright column.

[0010] By adopting the above technical solution, the rotating connection of the horizontal column allows the punch head of the hydraulic cylinder to be tilted for drilling, thereby improving the drilling adaptability of the device.

[0011] Preferably, a second screw is rotatably connected to the inner cavity of the horizontal column, a third motor is fixedly connected to the side of the horizontal column away from the vertical column, and the sliding seat is threadedly connected to the second screw. The third motor is used to drive the second screw to rotate, thereby causing the sliding seat to slide along the length direction of the second screw.

[0012] By adopting the above technical solution, the range of drilling positions has been further expanded, thereby meeting the drilling requirements of more bumpers and improving the practicality of the device as well as the stability and accuracy during drilling.

[0013] Preferably, several support plates are also fixedly connected to the top of the box body, and the support plates are used to support the middle of the bumper.

[0014] By adopting the above technical solution, the bumper is supported by a support plate, reducing the sag of the middle part of the bumper and thus ensuring the positional accuracy during drilling.

[0015] Preferably, the main body of the box is also equipped with a waste bin, and the top of the main body of the box is also provided with several discharge holes, through which the waste can fall into the waste bin.

[0016] By adopting the above technical solutions, the efficiency of the drilling process is improved, the accumulation of waste materials is avoided from affecting the positioning accuracy of the bumper, and the waste materials are centrally processed, thereby improving the working efficiency of the drilling process.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] 1. By fixing the bumper to the fixed component of the box body, the drive component drives the hydraulic cylinder to slide into place before drilling holes in the bumper, which meets the drilling requirements of different hole positions and improves work efficiency.

[0019] 2. The rotating connection of the horizontal column allows the hydraulic cylinder's punch head to tilt and punch holes, increasing the device's punching range. Combined with the third motor and third screw, this further expands the range of punching positions, thus meeting the punching requirements of more bumpers and improving the device's practicality, stability, and accuracy during punching.

[0020] 3. The bumper is supported by a support plate to reduce the sag of the middle part of the bumper, thereby ensuring the positional accuracy when drilling. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] Reference Figure 1A punching device for automotive bumpers includes a housing body 1, a fixing component 2 disposed above the housing body 1, a column 3 slidably connected to the back of the housing body 1, a first driving component 4 for driving the column 3 to slide, and a hydraulic cylinder 5 fixed to the column 3. The hydraulic cylinder 5 is located above the housing body 1, and a punching head is detachably mounted on the end of the cylinder's rod, with the rod facing the bumper. The first driving component 4 includes a first screw 41 rotatably connected to the housing body 1, a guide rod 42 fixedly connected to the housing body 1, and a first motor 43 fixedly connected to the housing body 1. The output shaft of the first motor 43 is fixedly connected to the first screw 41. The column 3 is threadedly connected to the first screw 41 and slidably connected to the guide rod 42. By fixing the bumper to the fixing component 2 of the housing body 1, the driving component drives the hydraulic cylinder 5 to slide into position before punching holes in the bumper, satisfying the punching requirements for different hole positions and improving work efficiency.

[0026] Preferably, the fixing component 2 includes a fixing plate 21 fixedly connected to the top of the box body 1 and a sliding plate 22 slidably connected to the box body 1. A movable rod 23 is provided on the side of the sliding plate 22 away from the fixing plate 21. A spring 24 is sleeved on the movable rod 23. The two ends of the spring 24 abut against the box body 1 and the sliding plate 22 respectively, driving the sliding plate 22 to slide, thus clamping the bumper between the sliding plate 22 and the fixing plate 21. In this embodiment, there are two of each of the fixing plate 21, sliding plate 22, movable rod 23, and spring 24, located at both ends of the top of their respective box bodies 1, thereby clamping and fixing both ends of the bumper. When placing the bumper, the spring 24 is first compressed to cause the sliding plate 22 to slide away from the fixing plate 21. One end of the bumper is then placed between the sliding plate 22 and the fixing plate 21. The compressed spring 24 will cause the sliding plate 22 to clamp the bumper. The sliding plate 22 and the fixing plate 21 clamp and fix the bumper, which improves the positioning accuracy of the bumper before drilling and reduces the time for clamping and disassembling the bumper, thereby improving the drilling efficiency.

[0027] Preferably, the column 3 includes an upright column 31 slidably connected to the box body 1, a horizontal column 32 rotatably connected to one side of the upright column 31, and a sliding seat 33 slidably connected to the horizontal column 32. The hydraulic cylinder 5 is fixedly connected to the sliding seat 33, and a second motor 34 for driving the horizontal column 32 to rotate is fixedly connected to the upright column 31. The rotatable connection of the horizontal column 32 allows the punch head of the hydraulic cylinder 5 to be tilted for drilling, improving the drilling adaptability of the device.

[0028] Preferably, a second screw 35 is rotatably connected to the inner cavity of the horizontal column 32, and a third motor 36 is fixedly connected to the side of the horizontal column 32 away from the vertical column 31. The sliding seat 33 is threadedly connected to the second screw 35, and the third motor 36 drives the second screw 35 to rotate, thereby causing the sliding seat 33 to slide along the length direction of the second screw 35. This further expands the range of drilling positions, thereby further meeting the drilling requirements of more bumpers, improving the practicality of the device, as well as the stability and accuracy during drilling.

[0029] Preferably, a plurality of support plates 6 are fixedly connected to the top of the main body 1, and the support plates 6 are used to support the middle of the bumper. In this embodiment, there are four support plates 6, and the shape of the support plates 6 is adapted to the shape of the bumper, so as to better fit the contact position of the bumper. At the same time, the support plates 6 are detachably installed on the main body 1, and more bumper shapes can be adapted by replacing the support plates 6, thereby improving the practicality of the device. By supporting the bumper with the support plates 6, the sag of the middle of the bumper is reduced, thereby ensuring the positional accuracy when drilling.

[0030] Preferably, the main body 1 of the box also includes a waste bin, and the top of the main body 1 is provided with several discharge holes 11, through which waste material can fall into the waste bin. In this embodiment, there are twenty-two discharge holes 11, and the number and position can be adjusted according to the actual discharge situation. This improves the efficiency of the drilling process, avoids waste accumulation affecting the positional accuracy of the bumper fixing, and centrally processes waste, thereby improving the working efficiency of the drilling process.

[0031] The implementation principle of the automobile bumper punching processing device of this application is as follows: the bumper to be punched is clamped by the sliding plate 22 and the fixed plate 21 on the top of the box body 1. The first drive motor drives the first screw 41 to slide the column 31. At the same time, the second drive motor drives the horizontal column 32 to rotate to a suitable angle. The third drive motor drives the second screw 35 to rotate and drive the sliding seat 33 to move, so that the punch head of the hydraulic cylinder 5 is aligned with the position of the bumper to be punched and punches. The above steps are repeated to complete the punching operation of the entire bumper. The device is simple and quick to load and unload the bumper, improves the efficiency and accuracy of bumper punching, and is equipped with a waste bin to further improve work efficiency.
