Description

Technical Field

[0001] This utility model relates to the field of vehicle body fixing technology, and in particular to a body-in-white fixing device. Background Technology

[0002] In automobile manufacturing, the body-in-white is the foundation of the car body, encompassing structural components, welded assemblies of body panels, and key components such as front fenders, doors, and engine hoods. It is subsequently integrated with various functional systems and accessories to ultimately form a complete vehicle. Body-in-white fixing devices are specialized equipment used on the body-in-white production line to precisely position and reliably clamp various stamped sheet metal parts and sub-assemblies (such as side panels, floor, and roof), ensuring that each component maintains its preset relative position during assembly, thereby guaranteeing the manufacturing precision of the car body.

[0003] For example, a prior art publication number CN215747523U describes a fixing device for a body-in-white. This prior art sets a second positioning mechanism corresponding to different car models on a turntable. When it is necessary to process workpieces of different car models, the corresponding second positioning mechanism is rotated to a predetermined position, so that the second positioning mechanism can be combined with a universal first positioning mechanism to fix the workpieces together. The switching speed is fast and convenient, and it can effectively avoid the problem of reduced workpiece processing efficiency.

[0004] However, existing body-in-white fixing devices still have shortcomings in practical applications: most of these devices are placed directly on the workshop floor, relying solely on their own support structure to contact the ground for positioning, and their stability is highly dependent on the flatness of the ground. Due to the large weight of the body-in-white, the fixing device is subjected to continuous loads over a long period, which can easily lead to overall settlement or local tilting of the fixing device. This problem can directly cause the positioning reference of the body-in-white to shift, resulting in positioning inaccuracies. This may not only cause accidental scratches and paint damage to the body-in-white during clamping or assembly, but also seriously affect the assembly accuracy of subsequent parts such as doors, leading to quality problems. Utility Model Content

[0005] To address the issues with the body-in-white fixing device mentioned in the background section, this invention improves the stability of the body-in-white fixing by setting a clamp and positioning component on the top of the fixing frame. A level is used to check the horizontal state of the fixing frame, preventing tilting of the fixing frame from affecting the splicing accuracy between the body-in-white and the door. Furthermore, an electric push rod and foot pads work together to automatically lift the fixing frame and separate it from the ground. The position of the foot pads can also be adjusted via a slider, improving practicality. The level of the fixing frame can be quickly adjusted without needing to re-use the lifting equipment, making operation convenient and improving adjustment efficiency.

[0006] This utility model provides the following technical solution: a body-in-white fixing device, including a fixing frame, a plurality of evenly distributed mounting plates fixed on the top of the fixing frame, a support column fixed on the top of each of the mounting plates, a clamp and a positioning component fixed on the top of each of the support columns, a plurality of equally spaced support legs fixed on both sides of the bottom of the fixing frame, a sliding groove opened on both sides of the bottom of the fixing frame, a slider slidably disposed inside each of the two sliding grooves, a lifting mechanism fixed at the bottom of each slider, the lifting mechanism including an electric push rod, and a foot pad fixed at the bottom end of the piston rod of the electric push rod.

[0007] Furthermore, each slider has a connecting groove at its bottom, and each electric push rod has a connecting block fixed at its top that matches the connecting groove. The connecting block is located inside the connecting groove and fixed to the slider. The connection between the connecting block and the connecting groove facilitates the disassembly and replacement of the electric push rod and foot pad by the staff.

[0008] Furthermore, each slider has fixing holes on both the front and rear sides at the bottom, and fastening bolts are installed inside the fixing holes. The top walls of the two slides are machined with multiple equally spaced threaded holes. The fastening bolts are threadedly connected to one of the threaded holes to fix the slider, which makes it easy for the staff to quickly adjust the position of the slider.

[0009] Furthermore, each foot pad has multiple mounting holes arranged in a circular array on its top. The mounting holes are designed to fix the foot pad in place, thereby improving the stability of the foot pad and the electric push rod lifting the frame. The bottom surface of each foot pad is machined with anti-slip texture, which improves the anti-slip properties of the foot pad and further enhances the stability when lifting the frame.

[0010] Furthermore, the top of the fixing frame is provided with multiple detection slots arranged in a circular array, and each detection slot is fixed with a level for detecting the levelness of the fixing frame.

[0011] Furthermore, a plurality of evenly distributed lifting rings are fixedly provided on the top of the fixing frame.

[0012] Furthermore, the outer walls of the fixing frame, mounting plate, support column, and support leg are all coated with wear-resistant paint.

[0013] Furthermore, the cross-sections of the two grooves and each slider are all T-shaped to prevent the slider from detaching from the groove, thereby improving the stability of the slider during movement.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This utility model improves the stability of the body-in-white by setting a clamp and positioning component on the top of the fixing frame, and uses a level to detect and provide real-time feedback on the horizontal status of the fixing frame, which makes it easy for operators to quickly check the tilt of the reference surface and effectively avoid the offset of the positioning reference of the body-in-white caused by the tilt of the fixing frame, thus ensuring the splicing accuracy of the body-in-white with parts such as doors and engine hood. In addition, the electric push rod and foot pads can be used to automatically lift the fixed frame and separate it from the ground. The position of the foot pads can also be adjusted by the slider, which improves practicality. There is no need to call up the lifting equipment for overall relocation. The operation process is simple and convenient, which shortens the leveling operation time and significantly improves the adjustment efficiency in the production process. At the same time, it effectively compensates for the accuracy deviation caused by ground settlement or long-term use of equipment, and ensures the stability of the assembly quality of the body-in-white.

[0017] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.

[0018] Please see Figures 1-5This utility model provides a body-in-white fixing device, including a fixing frame 1. Multiple evenly distributed mounting plates 2 are fixedly fixed to the top of the fixing frame 1. Support columns 3 are fixedly fixed to the top of each mounting plate 2. Clamps 4 and positioning elements 5 are respectively fixed to the top of each support column 3. Multiple equally spaced support legs 6 are fixed to both sides of the bottom of the fixing frame 1. Slide grooves 7 are opened on both sides of the bottom of the fixing frame 1. Sliding sliders 8 are slidably disposed inside each of the two slide grooves 7. A lifting mechanism 9 is fixedly fixed to the bottom of each slider 8. The lifting mechanism 9 includes an electric push rod 901. A foot pad 902 is fixedly fixed to the bottom end of the piston rod of the electric push rod 901. Furthermore, the cross-sections of the two slide grooves 7 and the cross-section of each slider 8 are T-shaped, preventing the slider 8 from automatically detaching from the slide grooves 7, thereby improving the stability of the slider 8 during movement.

[0019] Each slider 8 has a connecting groove 903 at its bottom, and each electric push rod 901 has a connecting block 904 that matches the connecting groove 903 at its top. The connecting block 904 is located inside the connecting groove 903 and fixed to the slider 8. Each slider 8 has a fixing hole 10 on both the front and rear sides at its bottom. The fixing hole 10 has a fastening bolt 11 inside it. The top walls of the two slide grooves 7 are machined with multiple equally spaced threaded holes 12. The fastening bolt 11 is threadedly connected to one of the threaded holes 12.

[0020] The top of the mounting bracket 1 has multiple detection slots 14 arranged in a circular array. Each detection slot 14 is equipped with a level 15 for detecting the levelness of the mounting bracket 1. The level 15 is a common measuring tool for measuring small angles. It is mainly used to measure the horizontal position of the relative positions of machine parts and the flatness, straightness and perpendicularity of equipment during installation. The level tube of the level 15 is made of glass and the inner wall is a curved surface with a certain radius of curvature. The tube is filled with liquid, such as alcohol, ether and their mixtures. When the level 15 is tilted, the air bubble in the level tube will move towards the higher end of the level 15 due to gravity, thereby determining the position of the horizontal plane. The level 15 allows the staff to quickly check the levelness of the mounting bracket 1.

[0021] In practice, the workers first use a hoist to move the car body to the top of the mounting frame 1. Then, using multiple positioning pins on the top of the support column 3, the car body is precisely positioned and reliably fixed using two sets of clamps 4. Next, the car door is assembled with the car body using a door fixing fixture. After each car body is fixed, the workers need to check the level of the mounting frame 1 using multiple levels 15 to avoid affecting the splicing accuracy of the car body and the door due to the tilt of the mounting frame 1. If the mounting frame 1 is found to be not level and needs to be adjusted, the workers can first adjust the position of the slider 8, and then use the electric push rod 901 to extend and push the foot pad 902 to contact the ground, thereby lifting the entire mounting frame 1 and detaching it from the ground. Subsequently, the workers adjust the mounting frame 1 to a level state by adding shims. There is no need to call up the hoist again, making the operation convenient and improving the adjustment efficiency.

[0022] Each foot pad 902 has multiple mounting holes 13 arranged in a circular array on its top, and the bottom surface of each foot pad 902 is machined with anti-slip texture. The mounting holes 13 are designed to fix the foot pad 902, thereby improving the stability of the foot pad 902 and the electric push rod 901 in lifting the fixed frame 1. The anti-slip texture design can improve the anti-slip properties of the foot pad 902, further improving the stability when lifting the fixed frame 1.

[0023] like Figure 1 As shown, a plurality of evenly distributed lifting rings 16 are fixedly provided on the top of the fixed frame 1. By providing a plurality of lifting rings 16, the stability of the fixed frame 1 during the lifting process can be improved.

[0024] Furthermore, wear-resistant coatings are applied to the outer walls of the mounting bracket 1, mounting plate 2, support column 3, and support leg 6. The wear-resistant coating can be a solvent-free polyurea coating. Polyurea coatings are formed into a film through high-pressure spraying, featuring fast curing, high toughness, and wear and impact resistance. This improves the wear resistance and service life of the entire body-in-white mounting system. Moreover, solvent-free products are completely free of volatile organic compounds (VOCs), producing virtually no odor during construction and use, reducing the impact on worker health and making them suitable for body-in-white mounting systems.

[0025] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
