Description

Technical Field

[0001] This utility model relates to the technical field of fender auxiliary tools, and more specifically, to a simple fender fixture and inspection tool. Background Technology

[0002] In the past, the headlights of the vehicles were two independently installed headlights, with one headlight corresponding to the installation position of one fender. The headlights and fenders were positioned on one side, and the fenders could be adjusted on one side according to the gap of the hood.

[0003] However, current vehicle designs have replaced the two independently mounted headlights with a single, continuous light strip. The installation of this continuous light strip requires maintaining a consistent relative distance between the mounting points on both fenders to ensure proper assembly. This places high precision requirements on the mounting points, and the mating surfaces are complex. The design inherently presents a risk of exceeding tolerances in the clearance / step difference between the continuous light strip and the fender. Based on experience, the average deviation rate is predicted to be approximately 8% (including extreme deviations), with a single batch potentially exceeding 15%. Furthermore, during vehicle assembly, the lack of a reference benchmark at the fender mating point makes it difficult to quickly assess the impact of various dimensional rings when gap / step difference appearance issues arise after vehicle assembly. This is an industry-wide challenge, difficult to analyze, impacting the overall vehicle's marketability and making rework difficult. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology in that it is difficult to guarantee the opening of the mounting points of the two fenders, and to provide a simple fender fixture and inspection tool to facilitate the guarantee of the opening of the mounting points of the two fenders.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A simple fender fixture is provided, comprising a mounting frame, a fixing component, and two sets of positioning components. The fixing component is disposed on the mounting frame, and the two sets of positioning components are respectively disposed at both ends of the mounting frame.

[0007] This utility model discloses a simplified fender mounting fixture. When installing two fenders on both sides of a vehicle frame, the mounting bracket is fixed to the desired fender positions on the frame using fixing components. The two fenders are placed on either side of the mounting bracket, and the positioning components are used to position the fenders. After positioning, the fenders are fixed to the frame. Once fixed, the fixture is removed, and the process proceeds to the next step. By setting the mounting bracket to fix the opening of the two sets of positioning components, and using the two sets of positioning components to install the fenders on both sides respectively, the opening of the fender mounting points on both sides can be easily guaranteed.

[0008] Furthermore, the positioning assembly includes a first pin positioning assembly and a first surface positioning assembly, both of which are connected to the mounting bracket. During positioning, the first pin positioning assembly is used to position the holes on the fenders using pin holes, and then the first surface positioning assembly is used to position the mounting surfaces of the fenders using surfaces. Combining pin hole positioning and surface positioning, the fenders on both sides are positioned and installed, facilitating accurate positioning.

[0009] Furthermore, the first pin positioning assembly includes a Z-axis positioning pin structure and a Y-axis positioning pin structure, both of which are connected to the mounting bracket. The Z-axis positioning pin structure positions the fender in the X and Y directions, while the Y-axis positioning pin structure positions the fender in the Z direction.

[0010] Furthermore, the Z-axis positioning pin structure includes a sliding seat, a flipping structure, and a sliding pin. The sliding seat is mounted on the mounting bracket, and the sliding pin is slidably connected to the sliding seat. Both ends of the flipping structure are connected to the sliding seat and the sliding pin, respectively. After the fender is abutted against the first positioning assembly, rotating the flipping structure causes the sliding pin to slide within the sliding seat, inserting the sliding pin into the positioning hole of the fender to position it, making positioning convenient.

[0011] Furthermore, the flipping structure includes a first connecting rod, a second connecting rod, and a handle. The two ends of the first connecting rod are rotatably connected to the sliding seat and the handle, respectively. One end of the second connecting rod is fixedly connected to the handle, and the other end is rotatably connected to the sliding pin. Rotating the handle causes the second connecting rod to move, and under the constraint of the first connecting rod, the second connecting rod causes the sliding pin to slide within the sliding seat, thereby inserting the sliding pin into the positioning hole of the fender or separating the sliding pin from the fender.

[0012] Furthermore, the Z-axis positioning pin structure has two sets: one set has a circular sliding pin, and the other set has a diamond-shaped sliding pin. By setting two sets of Z-axis positioning pin structures, positioning becomes more stable and accurate. Over-positioning is avoided by setting the two sets of Z-axis positioning pin structures to circular and diamond-shaped pins respectively.

[0013] Furthermore, the sliding pin includes a pin rod and a pin head, the pin head being detachably connected to the pin rod, the pin rod being slidably connected to the sliding seat, and both ends of the flip structure being connected to the sliding seat and the pin rod, respectively. By allowing the pin head to be detachably connected to the pin rod, different pin heads can be replaced according to different positioning holes, making this fixture suitable for the installation of fenders on different vehicle models.

[0014] Furthermore, the fixing assembly includes a second pin positioning assembly and a second surface positioning assembly, both of which are connected to the mounting bracket. The mounting bracket is securely connected to the vehicle frame via pin positioning and surface positioning, making the connection convenient.

[0015] Furthermore, the mounting bracket is a telescopic bracket. By changing the length of the mounting bracket, i.e., changing the distance between the two sets of positioning components, this fixture can be adapted to install fenders on different vehicle models.

[0016] This utility model also provides a simple fender inspection tool, including two sets of inspection surface contours and the simple fender fixture described above, wherein the two sets of inspection surface contours are respectively located at both ends of the mounting frame.

[0017] This utility model's simple fender inspection tool, when the installation position of the fender needs to be inspected after the fender installation is completed, fixes the mounting bracket to the vehicle frame through a fixing component, and abuts the two sets of inspection surface contours against the two fenders respectively. By observing the fit effect between the inspection surface contours and the two fenders, the installation effect of the two fenders can be seen intuitively, thus making it easier to ensure the opening of the installation points of the two fenders.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. The present invention provides a simple fender fixture and inspection tool, which fixes the opening of two sets of positioning components by setting a mounting frame, and installs the two fenders on both sides by using the two sets of positioning components respectively, thereby facilitating the ensuring of the opening of the mounting points of the two fenders.

[0020] 2. The present invention provides a simple fender fixture and inspection tool. The Z-direction positioning pin structure includes a sliding seat, a flipping structure and a sliding pin. By rotating the flipping structure, the sliding pin is driven to slide in the sliding seat. The sliding pin is inserted into the positioning hole of the fender to position the fender, which is convenient. Attached Figure Description

[0028] Example 1

[0029] This embodiment is the first embodiment of a simplified fender assembly, such as... Figure 1As shown, it includes a mounting bracket 100, a fixing component 200 and two sets of positioning components 300. The fixing component 200 is mounted on the mounting bracket 100, and the two sets of positioning components 300 are respectively located at both ends of the mounting bracket 100.

[0030] like Figure 2 As shown, the positioning component 300 includes a first pin positioning component 400 and a first surface positioning component 500, both of which are connected to the mounting bracket 100. During positioning, the first pin positioning component 400 is used to position the holes on the fender, and the first surface positioning component 500 is used to position the mounting surface of the fender. Combining pin hole positioning and surface positioning, the fenders on both sides are positioned and installed, facilitating accurate positioning. In this embodiment, the first surface positioning component 500 is a limiting block, which is arranged in the Y direction. There are two limiting blocks, which are located at both ends of the fender and respectively conform to the contour surfaces of both ends of the fender.

[0031] like Figure 2 As shown, the first pin positioning assembly 400 includes a Z-direction positioning pin structure 410 and a Y-direction positioning pin structure 420, both of which are connected to the mounting bracket 100. The Z-direction positioning pin structure 410 positions the fender in the X and Y directions, while the Y-direction positioning pin structure 420 positions the fender in the Z direction. In this embodiment, the Z-direction positioning pin structure 410 and the Y-direction positioning pin structure 420 are located at the upper and lower ends of the fender, respectively, allowing the fender to better fit with the first positioning assembly 500. The Z-direction positioning pin structure 410 is fixed to the positioning hole of the front fender, and the Y-direction positioning pin structure 420 is inserted into the headlight bracket hole on the side of the vehicle body.

[0032] like Figure 2 As shown, the fixing assembly 200 includes a second pin positioning assembly 210 and a second surface positioning assembly 220, both of which are connected to the mounting bracket 100. The mounting bracket 100 is securely connected to the vehicle frame via pin positioning and surface positioning, making the connection convenient.

[0033] In this embodiment, the second pin positioning component 210 and the second surface positioning component 220 are located at the bottom of the mounting bracket 100. Two second pin positioning components 210 are provided, each connected to one end of the mounting bracket 100. The positions of the two second pin positioning components 210 are aligned with the positioning holes of the front bulkhead connecting plate. The two second pin positioning components 210 are respectively designed as a circular pin and a diamond pin. The circular pin, by engaging with the circular hole, restricts two translational degrees of freedom (movement in the X and Y directions). The diamond pin restricts only one translational degree of freedom (e.g., the Y direction) along its major axis, while leaving a gap in the minor axis direction (X direction). If both pins are circular pins, a small error in the hole spacing can prevent the two pins from being inserted simultaneously, causing interference. The diamond pin, by reducing the constraint in one direction, retains only single-direction positioning, thus eliminating the over-positioning problem. The second surface positioning component 220 is positioned along the Z-direction and fits against the Z-direction surface of the front bulkhead connecting plate.

[0034] Mounting bracket 100 is a telescopic bracket, with two sets of positioning components 300 located at both ends of the telescopic bracket. By changing the length of mounting bracket 100, i.e., changing the distance between the two sets of positioning components 300, this fixture can be adapted to install fenders on different vehicle models. For ease of operation, a handle can also be provided on mounting bracket 100.

[0035] The working principle of a simple fender fixture in this embodiment is as follows:

[0036] When installing the two fenders on both sides of the vehicle frame, the mounting bracket 100 is fixed to the desired fender positions on the frame using the fixing components 200. The two fenders are placed on either side of the mounting bracket 100, and the positioning components 300 are used to position the fenders. After positioning, the fenders are fixed to the frame. Once fixed, the fixture is removed, and the process proceeds to the next step. By setting the mounting bracket 100 to fix the opening of the two sets of positioning components 300, and by using the two sets of positioning components 300 to install the fenders on both sides respectively, it is easier to ensure the opening of the fender mounting points, achieve overall vehicle quality, reduce rework, increase efficiency, improve overall vehicle quality, and increase the first-pass yield.

[0037] Specifically, the second pin positioning component 210 is fixed to the positioning hole of the front bulkhead connecting plate. After inserting the second pin positioning component 210 into the positioning hole of the front bulkhead connecting plate, the second positioning component 220 is attached to the Z-direction surface of the front bulkhead connecting plate. Then, the fender is attached to the first positioning component 500 in the Y-direction, the Z-direction positioning pin structure 410 is fixed to the positioning hole of the front fender, the Z-direction bolts of the fender are tightened, the Y-direction positioning pin structure 420 is inserted into the headlight bracket hole on the side of the vehicle, and finally the Y-direction bolts of the fender are tightened. After installation, the fixture is removed.

[0038] Example 2

[0039] This embodiment is a second embodiment of a simplified fender fixture. This embodiment is similar to the first embodiment, except that, as shown in the following... Figure 3 As shown, the Z-axis positioning pin structure 410 includes a sliding seat 411, a flipping structure 412, and a sliding pin 413. The sliding seat 411 is mounted on the mounting bracket 100, and the sliding pin 413 is slidably connected to the sliding seat 411. The two ends of the flipping structure 412 are respectively connected to the sliding seat 411 and the sliding pin 413. After the fender abuts against the first positioning assembly 500, rotating the flipping structure 412 causes the sliding pin 413 to slide within the sliding seat 411, inserting the sliding pin 413 into the positioning hole of the fender to position the fender, making positioning convenient.

[0040] like Figure 4 As shown, the flip structure 412 includes a first connecting rod 414, a second connecting rod 415, and a handle 416. The two ends of the first connecting rod 414 are rotatably connected to the sliding seat 411 and the handle 416, respectively. One end of the second connecting rod 415 is fixedly connected to the handle 416, and the other end is rotatably connected to the sliding pin 413. Rotating the handle 416 causes the second connecting rod 415 to move. Under the constraint of the first connecting rod 414, the second connecting rod 415 causes the sliding pin 413 to slide within the sliding seat 411, thereby inserting the sliding pin 413 into the positioning hole of the fender or separating the sliding pin 413 from the fender. In this embodiment, there are two first connecting rods 414 and two second connecting rods 415. The two first connecting rods 414 are fixedly connected by a limiting block, and the two second connecting rods 415 are fixedly connected to both ends of the handle 416 respectively. The two first connecting rods 414 and the two second connecting rods 415 are located on both sides of the sliding pin 413 to prevent tilting when the sliding pin 413 is moved. At the same time, the limiting block can restrict the further rotation of the handle 416.

[0041] like Figure 4 As shown, the sliding pin 413 includes a pin rod 413a and a pin head 413b. The pin head 413b is detachably connected to the pin rod 413a, and the pin rod 413a is slidably connected to the sliding seat 411. The two ends of the flip structure 412 are connected to the sliding seat 411 and the pin rod 413a, respectively. By allowing the pin head 413b to be detachably connected to the pin rod 413a, different pin heads 413b can be replaced according to different positioning holes, making this fixture suitable for the installation of fenders on different vehicle models.

[0042] like Figure 2As shown, the Z-axis positioning pin structure 410 has two sets, located at both ends of the same side of the mounting bracket 100, i.e., at the left and right ends of the same fender. One set of Z-axis positioning pin structures 410 has a circular sliding pin 413, while the other set has a diamond-shaped sliding pin 413. By setting two sets of Z-axis positioning pin structures 410, positioning becomes more stable and accurate. By setting the two sets of Z-axis positioning pin structures 410 as circular and diamond-shaped pins respectively, over-positioning is avoided.

[0043] Example 3

[0044] This embodiment is a first embodiment of a simple fender inspection fixture, including two sets of inspection surface contours and a simple fender fixture provided in Embodiment 1 or Embodiment 2. The two sets of inspection surface contours are respectively located at both ends of the mounting frame 100.

[0045] The working principle of a simple fender inspection tool in this embodiment is as follows:

[0046] When the installation position of the fenders needs to be checked after installation, the mounting bracket 100 is fixed to the vehicle frame using the fixing component 200. Specifically, the fixing component 200 is installed on the headlight bracket, and the two sets of detection surface contours are respectively abutted against the two fenders. The fit between the detection surface contours and the two fenders is observed, which allows a direct view of the installation effect of the two fenders. This verifies the relative opening of the through-light mounting points on both sides of the fenders, ensuring that the through-lights can be properly assembled. This device can quickly determine the opening on both sides of the through-light mounting points on the fenders of the entire vehicle, as well as the required clearance between the through-lights and the fenders.
