Description

Technical Field

[0001] This utility model relates to the field of punching device technology, and in particular to a punching device for automobile bumpers. Background Technology

[0002] As an important component of the automotive safety system, the car bumper not only absorbs and mitigates external impacts and protects the vehicle body and occupants, but it is also an important element of the car's exterior design. With the rapid development of the automotive industry and the increasing demands of consumers for automotive safety performance and appearance, the design and manufacturing process of car bumpers are also constantly improving. In particular, in the punching process of the bumper, efficient and precise punching technology is crucial for improving the overall performance and aesthetics of the bumper.

[0003] A punching device for producing electric vehicle bumpers, with publication number CN211588201U, includes a counterweight, an adjusting mechanism, a limiting mechanism, and a driving mechanism. The counterweight has a C-shaped cross-section, and a sliding groove is formed at the bottom of its inner circumference. Multiple sets of equally spaced support holes are drilled on both sides of the inner circumference of the counterweight near the sliding groove. Two sets of symmetrical adjusting mechanisms connected to the support holes are located within the sliding groove. Two sets of symmetrical limiting mechanisms are located at the top of the adjusting mechanisms. A bumper body is positioned between the two sets of limiting mechanisms. A suitable linear motor is mounted on the top of the inner circumference of the counterweight via fasteners. The drive unit of the linear motor is connected to the top of the driving mechanism located above the bumper body. This punching device for producing electric vehicle bumpers can adapt to bumper bodies of different sizes and can be adjusted and fixed as needed.

[0004] The aforementioned prior art is cumbersome to use when fixing the bumper. It requires manually adjusting the placement of the bumper and then manually rotating the limit valve to fix the clamp to the bumper. This is cumbersome, inefficient, and the single fixing effect is not good. The impact force of the longitudinal punching can affect the positioning firmness. Furthermore, the punching point of the prior art is fixed and inconvenient to adjust, making it unsuitable for different punching processing needs. Therefore, corresponding improvements are required. Summary of the Invention

[0005] The purpose of this utility model is to provide a punching device for automobile bumpers to solve the problems mentioned in the background art, such as poor fixing effect and inconvenient adjustment of punching points in existing automobile bumper punching devices.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a punching device for automobile bumpers, comprising a punching frame and a guide groove, wherein the bottom of the outer side of the punching frame is provided with a guide groove, and a punching support platform is slidably connected inside the guide groove;

[0007] The top of the back of the punching frame is connected to a power motor via a support plate. The output shaft of the power motor passes through the punching frame and is fixed to a turntable. A rotating column is connected to one end of the turntable, and a swing arm is movably connected to the outside of the rotating column. A movable column is connected to one end of the swing arm, and a lifting plate is movably connected to the swing arm via the movable column. Guide components are provided on both sides of the lifting plate. A connecting block is connected to the bottom of the lifting plate, and a lifting block is fixed to the bottom of the connecting block. A punching drill rod is connected to the center of the bottom of the lifting block. Limiting mechanisms are provided on both sides of the lifting block. An adjustment component is provided at the bottom of the punching support platform.

[0008] Furthermore, the guiding assembly includes guide rails fixed to both ends of the outer side of the punching frame, and sliders are slidably connected to the outer side of each guide rail. One side of each slider is connected to one side of the lifting plate, and a fixing plate is bolted between the slider and the lifting plate.

[0009] Furthermore, the limiting mechanism includes a support plate, which is disposed outside the lifting block. A telescopic cylinder is connected to the top of the support plate, and a telescopic spring is connected inside the telescopic cylinder. One end of the telescopic spring is connected to a movable plate, and the movable plate is slidably connected to the telescopic cylinder. A telescopic rod is connected to one side of the movable plate, and one end of the telescopic rod passes through the support plate. A positioning block is connected to the bottom end of the telescopic rod.

[0010] Furthermore, the adjustment assembly includes two wall plates disposed at the bottom outer side of the punching frame, and a one-way lead screw is connected between the wall plates. One end of the one-way lead screw is connected to a drive motor, and the drive motor is fixed to the outside of the wall plate by a support plate.

[0011] Furthermore, the outer side of the unidirectional lead screw is threaded with a threaded block, and the top of the threaded block is connected to the bottom of the punching support platform. A guide plate is fixed on one side of the punching support platform, and one end of the guide plate extends into the guide groove and is slidably connected to the guide groove.

[0012] Furthermore, both sides of the punching support platform are fixed with clamping plates, and both sides of the punching support platform are threaded with screws, and one end of each screw is rotatably connected to a clamping plate, and the clamping plate is slidably connected to the punching support platform.

[0013] Furthermore, each screw has a handle connected to one end, and each handle has a positioning hole, through which a positioning pin is inserted to fix and limit the handle.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the car bumper punching device can synchronously position the car bumper during the punching process to improve the stability of punching, and the bumper can be moved horizontally to adjust the punching point to meet different punching processing requirements.

[0015] During the rotation of the turntable, the rotating column and the swing arm rotate synchronously. Under the limiting action of the guide rail, the rotational motion is converted into lifting motion, which can drive the lifting plate, connecting block and lifting block to move up and down, and drive the punching drill rod to move synchronously, so as to punch holes in the car bumper. During this process, the telescopic rod and the positioning block move down synchronously until the positioning block presses against the car bumper, so as to fix and limit it synchronously, avoid hole position deviation, improve punching accuracy, optimize punching quality and reduce subsequent processing costs.

[0016] Insert both ends of the car bumper between the clip plate and the clamp plate respectively. Then use the screw to push the clamp plate to move horizontally, so as to further fix and limit the two ends of the bumper and improve the positioning firmness.

[0017] The drive motor drives the one-way lead screw to rotate. The one-way lead screw is threadedly connected to the threaded block, which can make the threaded block move horizontally and drive the punching support table to move synchronously. During this process, the guide plate slides in the guide groove to guide the position of the car bumper laterally, so as to adjust the punching point and meet the needs of co-line production of bumpers of multiple models and specifications, thereby reducing the number of special equipment.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Please see Figures 1-5 The present invention provides the following technical solution: Example 1

[0027] To address the issues of poor positioning and positional misalignment during the punching process in existing automotive bumper punching devices, the following technical solution is proposed. Please refer to the following for details. Figure 1 , Figure 2 , Figure 4 , Figure 5 A punching device for an automobile bumper includes a punching frame 1 and a guide groove 101. The guide groove 101 is provided at the bottom of the outer side of the punching frame 1, and a punching support platform 19 is slidably connected inside the guide groove 101. A power motor 18 is connected to the top of the back of the punching frame 1 via a support plate, and the output shaft end of the power motor 18 passes through the punching frame 1 and is fixed to a turntable 2. A rotating column 3 is connected to one end of the outer side of the turntable 2, and a swing arm 4 is movably connected to the outer side of the rotating column 3. A movable column 5 is connected to one end of the swing arm 4. 4. A lifting plate 6 is movably connected to the movable column 5, and guide components are provided on both sides of the lifting plate 6. The guide components include guide rails 7 fixed to both ends of the outer side of the punching frame 1, and sliders 8 are slidably connected to the outer side of the guide rails 7. One side of the sliders 8 is connected to one side of the lifting plate 6. A fixing plate 9 is bolted between the sliders 8 and the lifting plate 6. A connecting block 10 is connected to the bottom of the lifting plate 6, and a lifting block 11 is fixed to the bottom of the connecting block 10. A punching drill rod 12 is connected to the center of the bottom of the lifting block 11.

[0028] In one embodiment, during use, the drive motor 18 drives the turntable 2 to rotate. During the rotation of the turntable 2, the rotating column 3 drives the swing arm 4 to rotate. Under the limiting action of the guide rail 7, the rotational motion is converted into up and down motion, and the lifting plate 6 slides along the guide rail 7, which in turn pushes the connecting block 10, the lifting block 11, and the punching drill rod 12 to move synchronously, thereby using the punching drill rod 12 to perform punching operations on the car bumper.

[0029] Limiting mechanisms 13 are provided on both sides of the lifting block 11. The limiting mechanism 13 includes a support plate 1301, which is located on the outside of the lifting block 11. A telescopic cylinder 1304 is connected to the top of the support plate 1301, and a telescopic spring 1306 is connected inside the telescopic cylinder 1304. A movable plate 1305 is connected to one end of the telescopic spring 1306, and the movable plate 1305 is slidably connected to the telescopic cylinder 1304. A telescopic rod 1302 is connected to one side of the movable plate 1305, and one end of the telescopic rod 1302 passes through the support plate 1301. A positioning block 1303 is connected to the bottom end of the telescopic rod 1302.

[0030] In this embodiment, during the downward movement of the lifting block 11, the support plate 1301, the telescopic rod 1302, and the positioning block 1303 move synchronously. This causes the positioning block 1303 to abut against the top of the car bumper, achieving longitudinal positioning. It also pushes the telescopic rod 1302 to retract into the telescopic cylinder 1304, compressing the telescopic spring 1306 until the punching drill rod 12 contacts the car bumper for punching. During the punching process, the positioning effect of the positioning block 1303 effectively prevents the car bumper from shifting, improving the punching accuracy and quality. Example 2

[0031] This embodiment differs from Embodiment 1 in that the punching point can be adjusted by using the adjustment component to meet different processing requirements. Therefore, the following technical solution is disclosed. Please refer to the following for details.

The adjustment assembly includes two wall plates 14 located at the bottom of the outer side of the punching frame 1, and a one-way screw 16 is connected between the wall plates 14. One end of the one-way screw 16 is connected to a drive motor 15, and the drive motor 15 is fixed to the outer side of the wall plate 14 by a support plate. A threaded block 17 is threadedly connected to the outer side of the one-way screw 16, and the top end of the threaded block 17 is connected to the bottom of the punching support platform 19. A guide plate 1901 is fixed on one side of the punching support platform 19, and one end of the guide plate 1901 extends into the guide groove 101 and is slidably connected to the guide groove 101.

[0032] In one embodiment, the drive motor 15 is driven to rotate the one-way lead screw 16. The one-way lead screw 16 is threadedly connected to the threaded block 17, thereby causing the threaded block 17 to move horizontally and drive the punching support table 19 to move synchronously. During this process, the guide plate 1901 slides in the guide groove 101 to limit and guide the movement of the punching support table 19, thereby driving the car bumper to move synchronously. The punching position can be adjusted to meet different punching processing requirements.

[0033] Both sides of the punching support platform 19 are fixed with clamping plates 20. Both sides of the punching support platform 19 are threaded with screws 22, and one end of each screw 22 is rotatably connected to a clamping plate 21, and the clamping plate 21 is slidably connected to the punching support platform 19. One end of each screw 22 is connected to a rotating handle 23, and each rotating handle 23 is provided with a positioning hole, and a positioning pin passes through the positioning hole to fix and limit the rotating handle 23.

[0034] In this embodiment, when punching holes in the car bumper, first, the two ends of the car bumper are clamped between the clamping plate 20 and the clamping plate 21. Then, the handle 23 is manually turned to drive the screw 22 to rotate. The screw 22 is threadedly connected to the punching support 19, thereby pushing the clamping plate 21 to move horizontally, which can fix and clamp the two ends of the car bumper to prevent positional displacement during the punching process.
