Description

Technical Field

[0001] This utility model relates to the field of automotive energy-absorbing box processing technology, and more specifically, it relates to a jig for processing automotive anti-collision beam energy-absorbing boxes. Background Technology

[0002] In the automotive manufacturing industry, the energy-absorbing box of the crash beam is a key component for ensuring vehicle collision safety, and its processing quality directly affects the passive safety performance of the vehicle. Cutting and welding are common processes in the manufacturing of the crash beam energy-absorbing box, and the proper design and use of fixtures play a crucial role in ensuring the accuracy and stability of these processes.

[0003] Currently, most automotive crash beam energy-absorbing box processing fixtures on the market employ traditional clamping methods. These traditional fixtures typically achieve fixation by applying significant clamping force to specific areas of the energy-absorbing box. However, this method has several significant drawbacks. Firstly, traditional clamping methods often directly apply force to the processing area of ​​the energy-absorbing box. During cutting or welding, the fixture obstructs the processing area, preventing the processing equipment from accurately manipulating the target area. This significantly impacts processing accuracy, making it difficult for the processed energy-absorbing box to meet design requirements, thereby affecting the vehicle's collision safety performance.

[0004] On the other hand, when fixing the energy-absorbing box, the structural layout of traditional fixtures is prone to interference with cutting and welding equipment. During equipment operation, some parts of the fixture may collide with the cutting tool or welding electrode, which may not only damage the fixture and processing equipment, but also cause processing interruption, reduce production efficiency, and increase production costs.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0028] Please see Figure 1-7 The present invention provides the following technical solution:

[0029] Embodiment 1 includes a base 1 and a housing 2 disposed on top of the base 1. The jig for processing the energy-absorbing box also includes an abutment mechanism 3 and an adjustment mechanism 4. The abutment mechanism 3 is disposed on the side of the housing 2 and includes a first abutment part 31, a sliding part 32, and a second abutment part 33. The first abutment part 31 is slidably disposed on the side of the housing 2 and is used to abut against the inner cavity of the energy-absorbing box to be processed. The sliding part 32 is slidably disposed on top of the first abutment part 31. The second abutment part 33 is slidably disposed below the sliding part 32 and is used to abut against the inner cavity of the energy-absorbing box to be processed. The lower left end face of the second abutment part 33 has a chamfered right angle structure, and multiple protrusions are provided at the bottom of the end face of the second abutment part 33. The adjustment mechanism 4 is disposed on the housing 2 and is used to adjust the horizontal position of the first abutment part 31 and the second abutment part 33. The adjustment mechanism 4 can make the second abutment part 33 move in an upward or downward motion.

[0030] It should be noted that the second abutment part 33 is preferably made of rubber. First, the inner cavity of the automotive energy-absorbing box to be processed is abutted against the first abutment part 31 and the second abutment part 33 using either a robotic arm or manually. Using a robotic arm is preferred as it reduces worker fatigue and improves work efficiency. It should be noted that at this point, the automotive energy-absorbing box to be processed can be abutted against by the first abutment part 31 and the second abutment part 33. Since the abutment is applied to support the inner cavity of the automotive energy-absorbing box, the supporting force is only applied to the non-processing area. This ensures that subsequent cutting and welding equipment will not collide with or obstruct the first abutment part 31 and the second abutment part 33. Furthermore, it should be noted that to avoid interfering with cutting or welding the supported and fixed automotive energy-absorbing box, the processing area of ​​the automotive energy-absorbing box should be avoided.

[0031] See Figures 2-5 The abutting mechanism 3 also includes a mounting part 34; the mounting part 34 is disposed at the bottom of the sliding part 32, and the top of the mounting part 34 is provided with a plurality of abutting grooves that abut against the protrusion. When the second abutting part 33 slides toward the mounting part 34, the abutting grooves and the protrusion are in abutting state.

[0032] Specifically, both the second abutment portion 33 and the mounting portion 34 are preferably made of rubber. This allows the multiple evenly distributed protrusions on the bottom of the second abutment portion 33 to form a tight connection with the corresponding abutment grooves on the bottom of the mounting portion 34 when the second abutment portion 33 slides towards the mounting portion 34. During installation, it must be ensured that the protrusions and the abutment grooves are horizontally aligned. Simultaneously, during the installation operation, the second abutment portion 33 should remain in a sliding state towards the mounting portion 34. Through this sliding action, the second abutment portion 33 is ultimately securely installed onto the mounting portion 34. It should be noted that disassembly is achieved simply by pushing the second abutment portion 33 away from the mounting portion 34. It should also be noted that after installation, the second abutment portion 33 can abut against the bottoms of both the mounting portion 34 and the sliding portion 32.

[0033] See Figure 6 The adjusting mechanism 4 includes a limiting block 41, a toothed plate 42, and a rotating tooth 43. The limiting block 41 has a pair and is respectively disposed on both sides of the sliding part 32. The toothed plate 42 is disposed on the side of the sliding part 32. The rotating tooth 43 is rotatably disposed at the bottom of the sliding part 32 and meshes with the toothed plate 42. When the rotating tooth 43 rotates, it can drive the toothed plate 42 and the sliding part 32 to move.

[0034] Specifically, it should be noted that the input end of the rotating gear 43 is equipped with a miniature servo motor for driving the rotation of the rotating gear 43. When it is necessary to adjust the position of the second abutment part 33 so that it abuts against the inner cavity of the automotive energy-absorbing box to be processed, the rotating gear 43 first rotates. Then, when the rotating gear 43 rotates, it can drive the limiting block 41, the sliding part 32, the mounting part 34, and the second abutment part 33 to slide through the meshing tooth plate 42. This realizes the adjustment of the position of the second abutment part 33, which can be adjusted according to the inner cavity abutment support of different automotive energy-absorbing boxes.

[0035] See Figure 6 and Figure 7 The adjustment mechanism 4 also includes a rotating disk 44, an electric push rod 45, and a positioning plate 46; the rotating disk 44 is rotatably disposed on the side of the housing 2; there is a pair of electric push rods 45 and they are respectively disposed on the side of the rotating disk 44; the positioning plate 46 is disposed at the output end of the pair of electric push rods 45, and the positioning plate 46 is connected to the first abutment part 31 by fasteners.

[0036] Specifically, this is to adjust the position of the positioning plate 46, the first abutment part 31, and the second abutment part 33. It should be noted that the rotating disk 44 is connected to the housing 2 via bearings. When the electric push rod 45 is activated, it can drive the positioning plate 46, the first abutment part 31, and the second abutment part 33 to slide away from or towards the housing 2. This allows for adjustment of the position of the supported and abutted automotive energy-absorbing box to be processed.

[0037] See Figure 6 The adjustment mechanism 4 also includes a rotary motor 47 and a rotary rod 48; the rotary motor 47 is located on the side of the housing 2; the rotary rod 48 is rotatably located on the side of the housing 2, and the rotary rod 48 is connected to the output end of the rotary motor 47, and the positioning plate 46 is in clearance fit with the rotary rod 48, so that when the rotary motor 47 is started, it can drive the rotary rod 48 to rotate.

[0038] Specifically, the rotary motor 47 is preferably a servo motor. It should be noted that the outer side of the rotating rod 48 has a T-shaped groove to limit the horizontal sliding of the positioning plate 46. When the rotating rod 48 rotates, it can drive the positioning plate 46, the electric push rod 45, the first abutment part 31, and the second abutment part 33 to rotate. It should be noted that in this state, the first abutment part 31 and the second abutment part 33 are in a supported abutment state, supporting the energy-absorbing box of the car to be processed. When the electric push rod 45 is activated, it can slide through the pair of T-shaped grooves on the outer side of the positioning plate 46 and the rotating rod 48, which ensures that the rotation of the rotating rod 48 does not affect the adjustment of the rotational position of the rotating rod 48, the first abutment part 31, and the second abutment part 33.

[0039] See Figure 6 The adjustment mechanism 4 also includes a limiting plate 49; the limiting plate 49 is disposed on the side of the rotating rod 48, and the limiting plate 49 is in the shape of a disc.

[0040] Specifically, the limiting piece 49 is disc-shaped and is used to limit the movement distance of the positioning plate 46, preventing the positioning plate 46 from being pushed out of the outside of the rotating rod 48 by the electric push rod 45.

[0041] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
