Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive installation and testing tool structure, and in particular relates to an automotive plastic front fender installation and testing device. Background Technology
[0002] The front fender is a body panel that covers the front wheels of a car, located between the engine compartment and the front door. Its main functions are to shield the wheels, guide airflow, and enhance the car's appearance, while also providing some protection in the event of a minor collision. Compared to traditional metal materials, plastic front fenders offer a number of significant advantages, such as lightweight, corrosion resistance, pedestrian protection, resistance to minor impacts and ease of repair, design freedom, and cost-effectiveness, making them particularly suitable for lower-priced commercial minivans.
[0003] However, when installing plastic front fenders, gaps are more likely to appear between the plastic and the body surface compared to metal front fenders. This can cause the mounting holes of the plastic front fenders to align with the mounting holes of the body, and the accuracy of the mounting hole positions directly affects the assembly quality of the plastic front fenders with the body. Traditional installation inspection methods usually rely on manual tightening, combined with some simple inspection tools (such as feeler gauges), and manual visual inspection.
[0004] The above methods not only have unstable installation accuracy and low detection efficiency, but are also easily affected by human factors, leading to installation and measurement errors. Utility Model Content
[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an automotive plastic front fender installation inspection device to solve the problems in the prior art where gaps are more likely to occur between the plastic front fender and the body surface during installation, resulting in misalignment between the installation holes of the plastic front fender and the installation holes of the body, relying on manual pressing, and using some simple inspection tools (such as feeler gauges) for manual visual inspection, which leads to unstable installation accuracy and low inspection efficiency.
[0006] To achieve the above and other related objectives, this utility model provides an automotive plastic front fender mounting detection device, used for mounting a plastic front fender onto a car body and detecting the position of the mounting holes of the plastic front fender, including: The outer dimensions of the panel are greater than 5 / 6 of the outer dimensions of the plastic front fender; Multiple clamping blocks are fixed to the inner surface of the plate and are arranged at intervals. The clamping blocks at different positions can fit tightly against the plastic front fender. Press the handle to secure it to the outer surface of the plate. A side clamp is fixed to the outside of the plate and faces the inner surface of the plate; when the clamping block and the plastic front fender are in close contact, the side clamp is engaged with the vehicle body; Inspection holes are formed on the plate and / or the side clamp, at least three of which are not in a straight line; different inspection holes correspond to different mounting holes on the plastic front fender; The detection pin passes sequentially through the detection hole, the mounting hole on the plastic front fender, and the mounting hole on the vehicle body.
[0007] Optionally, there are multiple side clips, and when the clamping block and the plastic front fender are pressed together, the multiple side clips are respectively engaged in different slots on the vehicle body.
[0008] Optionally, there are two clamping handles.
[0009] Optionally, the plate body is provided with weight reduction holes.
[0010] Optionally, the plate and the side clamp are integrally cast from alloy steel.
[0011] As described above, the automotive plastic front fender mounting detection device of this utility model has at least the following beneficial effects: This automotive plastic front fender installation and testing device, through its structural design of a panel, clamping blocks, side clamps, testing holes, and testing pins, allows the operator to secure the plastic front fender to the vehicle body during installation. The operator then lifts the panel by holding the clamping handle, allowing the side clamps to also engage with the body. After the clamping blocks are in contact with the plastic front fender, the operator applies pressure to firmly press it down. The testing pin then passes sequentially through the testing holes, the mounting holes on the plastic front fender, and the mounting holes on the vehicle body. During the insertion of the testing pin, the operator can adjust the position of the plastic front fender and the device to ensure smooth insertion. After the pin is inserted, the operator presses the plastic fender firmly, then removes the main body of the device and the detection pin. Next, bolts are screwed into the mounting holes of the plastic fender and the vehicle body. After screwing in the bolts, the operator can use the device again to check the position of the installed bolts. The checking method is to align one detection hole of the plate with its corresponding mounting bolt and observe the alignment of the other detection holes with their respective mounting bolts. In other words, compared to existing technologies that rely entirely on manual tightening and simple testing tools (such as feeler gauges) for installation and testing, this device makes the installation accuracy of the plastic front fender more stable and improves testing efficiency.

[0017] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.
[0018] Please see Figures 1 to 4 It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.
[0019] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in the individual embodiments described below.
[0020] Please see Figures 1 to 3 This utility model provides an automotive plastic front fender 1 installation detection device 3, used to install the plastic front fender 1 onto the vehicle body 2 and to detect the position of the mounting holes of the plastic front fender 1, including: like Figure 1 and Figure 4 The outer dimensions of the plate 31 shown are 5 / 6 larger than the outer dimensions of the plastic front fender 1, thereby ensuring that the plate 31 can fully press the plastic front fender 1 to ensure the installation accuracy of the plastic front fender 1.
[0021] like Figure 1 and Figure 4 The clamping blocks 32 shown are fixed to the inner surface of the plate 31. There are multiple blocks arranged at intervals. Each clamping block 32 at a different position can fit tightly against the plastic front fender 1. That is, the shape of each clamping block 32 can be different or the same depending on the position of the corresponding plastic front fender 1. The clamping surface of the clamping block 32 can be various shapes such as round, square, trapezoidal, etc.
[0022] like Figure 4 The clamping handle 33 shown is fixed to the outer surface of the plate 31, making it convenient for the operator to clamp the plate 31.
[0023] like Figure 1 and Figure 4 The side clamp 34 shown is fixed to the outside of the plate 31 and faces the inner surface of the plate 31; when the clamping block 32 and the plastic front fender 1 are pressed together, the side clamp 34 is engaged on the vehicle body 2; the design of the side clamp 34 is beneficial for the operator to position the plastic front fender 1 when using the plate 31 to press it.
[0024] like Figure 4 The detection holes 35 shown are formed on the plate 31 and / or the side clamp 34, and there are at least three of them that are not in a straight line. Each of the detection holes 35 corresponds to a different mounting hole on the plastic front fender 1, so as to facilitate the subsequent adjustment of the position of the plastic fender by the operator. The reason why there are at least three detection holes 35 that are not in a straight line is that three points determine a plane, and at least three detection holes 35 that are not in a straight line can ensure the accuracy of the installation position of the plastic front fender 1.
[0025] like Figure 4 The detection pin 36 shown passes sequentially through the detection hole 35, the mounting hole on the plastic front fender 1, and the mounting hole on the body 2, and is used for position positioning and position measurement.
[0026] like Figure 1 and Figure 4As shown, the automotive plastic front fender 1 installation detection device 3, through its structural design of plate 31, clamping blocks 32, side clamps 34, detection holes 35, and detection pins 36, allows the operator to clamp the plastic front fender 1 onto the vehicle body 2 during installation. The operator then holds the clamping handle 33 to lift the plate 31, allowing the side clamps 34 to also clamp onto the vehicle body 2. After the multiple clamping blocks 32 are respectively attached to the plastic front fender 1, the operator applies force to press the plastic front fender 1 firmly. Figure 2 As shown, the detection pin 36 is then passed sequentially through the detection hole 35, the mounting hole on the plastic front fender 1, and the mounting hole on the vehicle body 2. During the process of the detection pin 36 passing through these holes, the operator can adjust the position of the plastic front fender 1 and the device to ensure smooth insertion of the detection pin 36. After the detection pin 36 is successfully inserted, the operator presses down on the plastic fender and then removes the main body of the device and the detection pin 36. Figure 3 As shown, bolts are then screwed into the mounting holes of the plastic fender and the mounting holes of the body 2. After screwing in the bolts, the operator can use this device again to check the position of the installed bolts. The check method is to align one of the check holes 35 of the plate 31 with its corresponding mounting bolt and observe the alignment of the other check holes 35 with their respective mounting bolts. In other words, compared with the existing technology that relies entirely on manual tightening and some simple testing tools (such as feeler gauges) for installation and testing, this device makes the installation accuracy of the plastic front fender 1 more stable and improves the testing efficiency.
[0027] In another implementation, please refer to Figure 1 and Figure 4 There are multiple side clips 34. When the pressing block 32 and the plastic front fender 1 are pressed together, the multiple side clips 34 are respectively engaged in different slots 21 on the body 2, so that the operator can accurately press the plastic front fender 1 into the correct position on the body 2.
[0028] In another implementation, please refer to Figure 4 There are two clamping handles 33, which are convenient for the operator to operate with both hands. At this time, the work of inserting the detection pin 36 requires the cooperation of another operator.
[0029] In another implementation, please refer to Figure 4 The plate 31 has weight-reducing holes 37, which not only saves production costs but also reduces the labor intensity of operators.
[0030] In other implementations, such as Figure 4 As shown, the plate 31 and the side clamp 34 are integrally cast from alloy steel to ensure the strength and durability of the device.
[0031] In summary, this utility model, through its structural design of plate 31, clamping blocks 32, side clamps 34, detection holes 35, and detection pins 36, allows the operator to secure the plastic front fender 1 of a car to the vehicle body 2 during installation. The operator then lifts plate 31 by holding clamping handle 33, allowing side clamps 34 to also engage with the vehicle body 2. Multiple clamping blocks 32 are then attached to the plastic front fender 1. The operator applies pressure to tighten the plastic front fender 1. The detection pin 36 then passes sequentially through the detection hole 35, the mounting hole on the plastic front fender 1, and the mounting hole on the vehicle body 2. During the insertion of the detection pin 36 through these holes, the operator can adjust the position of the plastic front fender 1 and the device to ensure the smooth insertion of the detection pin 36. Insertion; after the detection pin 36 is successfully inserted, the operator presses the plastic fender firmly, then removes the main body of the device and the detection pin 36, and then screws bolts into the mounting holes of the plastic fender and the vehicle body 2; after screwing in the bolts, the operator can use the device again to check the position of the installed bolts. The detection method is: align one detection hole 35 of the plate body 31 with its corresponding mounting bolt, and then observe the alignment of the other detection holes 35 with their respective mounting bolts; that is, compared with the existing technology that relies entirely on manual pressing and some simple detection tools (such as feeler gauges) for installation and detection, this device makes the installation accuracy of the plastic front fender 1 more stable and the detection efficiency improved. Therefore, this utility model effectively overcomes the shortcomings of the existing technology and has high industrial utilization value.
[0032] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
