Description

Technical Field

[0001] This utility model relates to the field of auxiliary tooling technology for automotive headlight installation, and in particular to an auxiliary device for automotive headlight installation. Background Technology

[0002] With the continuous development of autonomous driving and driver assistance technologies, automotive headlights are gradually upgrading towards integration, intelligence, and interactivity. Currently, most automotive headlights integrate sensing components such as cameras and radar sensors, enabling functions such as vehicle interaction and adaptive adjustment to road conditions, improving driving convenience and further enhancing driving safety. At the same time, the structure of headlights is becoming increasingly complex, with significantly higher requirements for weight and assembly precision, placing higher demands on their assembly processes and installation fixtures.

[0003] To meet the industrial design requirements of energy conservation, emission reduction, lower labor costs, and lightweight equipment, power-assisted equipment is increasingly used in the automotive assembly field. Replacing manual handling and assembly equipment with mechanical equipment has become an industry trend. Traditional power-assisted mechanical equipment typically consists of a basic track, a power-assisted robotic arm, an electric or pneumatic hoist, and specialized tooling fixtures and robotic arms. Currently, in the automotive headlight assembly process, most production sites still do not use high-precision specialized installation fixtures and auxiliary devices, and generally rely on direct manual installation or simple lifting tools for assistance.

[0004] The traditional assembly method has the following main problems:

[0005] Manual or simple lifting tools cannot guarantee uniform gaps and symmetrical left and right positions between the headlights and the vehicle body, resulting in low installation accuracy. The headlight position needs to be adjusted repeatedly during the assembly process, which is labor-intensive and involves a lot of repetitive work. Furthermore, simple tools can easily scratch the paint and exterior surfaces of the vehicle, affecting the overall appearance and product quality, and making it difficult to meet the requirements of high-precision assembly processes.

[0006] Traditional assembly processes are relatively outdated. The installation, positioning, and adjustment of a single headlight usually require two or more operators to work together, resulting in high labor costs and low overall assembly efficiency, which cannot meet the needs of efficient assembly line production.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0029] Combination Figures 1 to 9 As shown, this utility model discloses an auxiliary device for installing automotive headlights, comprising a bracket body 1, a first frame 2, and a second frame 3. A connecting flange 12 is provided at the top of the bracket body 1, and a swing joint 11 is provided between the bracket body 1 and the connecting flange 12. Operating handle assemblies 15 are fixed to both sides of the bracket body 1. A tilting cylinder 16 is provided at the middle of the rear end of the bracket body 1. The second frame 3 is provided at the bottom of the bracket body 1, and body connecting assemblies are provided on both sides of the second frame 3. The first frame 2 is provided at the top of the second frame 3, and fender connecting assemblies are provided on both sides of the front end of the first frame 2. The fender connecting assemblies are used to connect the auxiliary device to the fender. A third frame 4 is fixed at the bottom of the second frame 3, and headlight clamping assemblies are provided on both sides of the third frame 4.

[0030] The second frame 3 is hinged to the main support 1. The top of the tilting cylinder 16 is hinged to the main support 1. The piston rod at the bottom of the tilting cylinder 16 is hinged to the rear end of the second frame 3. The gun barrel 13 is fixed on both sides of the main support 1 by connecting rods. The tool box 14 is fixed to the rear end of the connecting rods on both sides of the main support 1.

[0031] Specifically, by operating the flip knob on the handle assembly 15, the flip cylinder 16 is activated, causing the second frame 3 and the third frame 4 to rotate 45°. The operator manually places the car headlight into the headlight clamping assembly, which then clamps and positions the headlight. The flip knob on the handle assembly 15 is operated again to activate the flip cylinder 16, causing the second frame 3 and the third frame 4 to rotate back to the installation position, ensuring the headlight's position aligns with the vehicle body's assembly position, ready for headlight assembly.

[0032] The entire device is moved to the vehicle body mounting position by operating the handle assembly 15. The angle and position of the device are adjusted using the swing joint 11 to align the fender connecting assembly with the positioning holes on the fender and achieve connection. Then, the device is fixed to the vehicle body to be assembled using the body connecting assembly, completing the device positioning. Subsequently, the headlight is securely connected to the vehicle body using fasteners such as fixing bolts. After the connection is completed, the headlight clamp assembly is used to release the headlight, thus completing the headlight installation.

[0033] Finally, the device is reset to its initial position by operating the handle assembly 15, ready for the next installation operation.

[0034] like Figures 1 to 5 as well as Figure 8 and Figure 9 As shown, the headlight clamping assembly includes headlight X-direction clamping cylinders 42 disposed on both sides of the frame 3 4, headlight Z-direction clamping cylinders 41 disposed on both sides of the top of the frame 3 4, headlight Z-direction clamping cylinders 45 disposed on both sides of the bottom of the frame 3 4, a headlight Y-direction clamping cylinder 43 disposed between the headlight Z-direction clamping cylinders 41 and 45, and the headlight Y-direction clamping cylinder 43 is mounted on the frame 3 4. Headlight guide limit blocks 44 are installed at the middle position of both sides of the front end of the frame 3 4 and at the top and bottom ends. Control buttons 46 are respectively disposed on both sides inside the frame 3 4.

[0035] Specifically, by operating the flip knob on the handle assembly 15, the flip cylinder 16 is activated, driving the second frame 3 and the third frame 4 to rotate 45°. The operator manually places the headlight into the headlight clamping assembly. Through the coordinated action of the headlight Z-axis clamping cylinder 41, the headlight X-axis clamping cylinder 42, the headlight Y-axis clamping cylinder 43, the headlight guide limit block 44, and the headlight Z-axis clamping cylinder 45, the headlight is stably clamped and positioned within the headlight clamping assembly.

[0036] Subsequently, the flip knob on the handle assembly 15 is operated again to start the flip cylinder 16, which drives the second frame 3 and the third frame 4 to rotate to the preset installation posture, waiting for subsequent assembly operations.

[0037] like Figures 1 to 7 As shown, the fender connection assembly includes a support frame 27 fixed at the middle of the front end of frame 1 2. Frame 1 2 and support frame 27 are connected to frame 2 3 via guide rails and sliders. Frame 2 3 has an X-type assembly cylinder 21 inside, located below frame 1 2, with its piston rod hinged to frame 1 2. Support plates 23 are respectively provided on both sides of the front end of frame 1 2, and a Y-axis centering assembly 22 is provided between the two support plates 23. The support plates 23 are connected to frame 1 2 via guide rails and sliders. A pin cylinder 24 is installed on the top of the support plate 23, and a fender pin 25 is provided at the bottom of the pin cylinder 24. Z-axis fender clamping cylinders 28 are provided on both sides of frame 2 3, and the Z-axis fender clamping cylinders 28 are installed on both sides of the bottom of frame 1 2.

[0038] The fender pin 25 is connected to the support plate 23 via a guide rail and a slider. An auxiliary operating handle 26 is fixed on one side of the support plate 23.

[0039] The body connection assembly includes a body X-direction clamping cylinder 31 located below the Z-direction fender clamping cylinder 28. The body X-direction clamping cylinder 31 is mounted on the top of the frame 3 4, and a positioning bracket 32 ​​is provided on one side of the body X-direction clamping cylinder 31.

[0040] Specifically, the support plate 23, through the cooperation of the guide rail, slider and Y-axis centering component 22, can drive the two fender pins 25 to move closer or further apart, flexibly adjusting the spacing of the fender pins 25 so that it can adapt to the installation structure of fenders of different car models and different widths, greatly improving the versatility and adaptability of the device, and solving the problem that traditional tooling can only adapt to a single car model and has poor applicability.

[0041] By operating the handle assembly 15, the device can be smoothly pushed to the vehicle body installation position. Activating the X-assembly cylinder 21 drives the frame 2 to move towards the vehicle body in the X direction, causing the fender pin 25, the Z-direction fender clamping cylinder 28, and the vehicle body X-direction clamping cylinder 31 to simultaneously approach the vehicle body assembly area, achieving alignment between the device and the vehicle body. Compared to manual handling and simple lifting tools, this device, through the vehicle body X-direction clamping cylinder 31, the Z-direction fender clamping cylinder 28, and the fender pin 25 forming a multi-positioning structure, ensures a constant relative position between the device and the vehicle body, effectively preventing offset and shaking during installation. Structurally, it ensures uniform gaps, left-right symmetry, and high contour matching between the headlight and the vehicle body perimeter, significantly improving headlight installation accuracy and eliminating redundant manual adjustments and alignments.

[0042] Then, the position of the fender pin 25 is finely adjusted by the Y-axis alignment component 22 to align it with the positioning hole on the fender; then the pin cylinder 24 is activated to drive the fender pin 25 downward to insert into the fender positioning hole, achieving positioning in the X and Y directions; finally, the Z-axis fender clamping cylinder 28 is activated to move downward along the Z direction and clamp the fender, completing the connection between the device and the vehicle body fender.

[0043] Once the device is connected to the vehicle body, the headlight held by the headlight clamping assembly automatically aligns with the headlight mounting position on the vehicle body, eliminating the need for repeated manual calibration. A single operator can complete the alignment, installation, and fastening of the headlights without the need for multiple people working together, significantly reducing the number of operators, lowering labor costs, and greatly improving assembly efficiency. This solves the problems of low efficiency, high labor intensity, and the need for multiple people in traditional manual installation methods.

[0044] After the headlights are securely installed on the vehicle body using bolts and other fasteners, the headlight Z-axis clamping cylinder 41, headlight X-axis clamping cylinder 42, headlight Y-axis clamping cylinder 43, and headlight Z-axis clamping cylinder 45 work together to release the clamping constraints on the headlights. Subsequently, each moving part resets in sequence, the device separates from the vehicle body, and the device is moved back to its initial position using the operating handle assembly 15, allowing the next round of headlight installation to begin. This achieves automated headlight assembly operations that are performed by a single person, efficiently, with high precision and continuous operation.

[0045] It should be noted that the fixture itself has high installation precision. The entire frame is machined in one piece to ensure planar and positional accuracy. High-precision machining is used for each connecting block and locating pin, and high-precision shims are added to ensure the accuracy of each component. Finally, the initial accuracy of the equipment is adjusted by using a coordinate measuring machine to meet the requirements. The positioning accuracy of the equipment is ±0.2mm.

[0046] The main frame and some welded components of the equipment are made of aluminum alloy, making the entire equipment lightweight and easier to operate.

[0047] The equipment has a no-load balancing function (after clamping the headlight, the equipment load switches to match the weight of the headlight, putting the clamp in a zero-gravity state, so that the operator can better operate the equipment to install the headlight); the equipment has a power failure and gas failure protection function, which can avoid safety accidents during production; the operating handle is integrated with the clamp, making it easier to operate, and this equipment only requires one person to meet production needs.

[0048] The equipment meets the requirements for precise tooling positioning and has functions for vehicle body mounting positioning and fender alignment. During installation, it ensures uniform clearance and positional accuracy around the headlights, improving production process quality. After the relative position of the headlights on the vehicle body is determined, the clamping cylinders on the equipment fix the headlights in their relative positions, preventing displacement of the headlights during installation and avoiding uneven clearance around the vehicle body.

[0049] The power-assisted device has a front-to-back and left-to-right angle balance adjustment mechanism, which can adaptively compensate for various angle errors during installation, making it convenient for alignment and installation.
