Description

Technical Field

[0001] This invention relates to the field of automobile manufacturing technology, and in particular to a positioning device. Background Technology

[0002] In automobile manufacturing, assembly precision is a crucial quality indicator that plays a vital role in the overall quality of the vehicle. As an important exterior component, the fender's assembly precision directly impacts the vehicle's appearance. Currently, before assembly, the matching status of the hood, doors, A-pillars, and fenders cannot be confirmed. This can easily lead to mismatches between the fenders and these components during assembly, resulting in frequent adjustments and reduced assembly efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a positioning device for positioning the door and the hood before fender assembly, so as to avoid mismatch problems during fender assembly and improve assembly efficiency.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A positioning device for positioning the vehicle doors and hood, the positioning device comprising:

[0006] Positioning the main frame;

[0007] A positioning component is disposed on the positioning main frame. The positioning component can abut against the edge of the door along the X-axis direction, and the positioning component can also clamp onto the door along the Y-axis direction.

[0008] A positioning detection component is disposed on the positioning main frame. The positioning detection component includes a positioning part and a first detection part that are connected to each other. The positioning part can be positioned along the Z-axis direction on the outer side of the door. The first detection part can form a first gap with the edge of the door.

[0009] The first detection block is disposed on the positioning main frame, and the first detection block can form a second gap with the A-pillar of the vehicle;

[0010] The positioning block and the second detection block are both disposed on the positioning main frame. The positioning block is used to abut against the front hood, and the second detection block can form a third gap between the positioning block abutting against the front hood and the front hood.

[0011] The position of the door is adjusted according to the first gap and the second gap, and the position of the hood is adjusted according to the third gap.

[0012] As an alternative, the upper surface of the first detection unit along the Z-axis is flush with the corresponding position on the outer side surface of the door.

[0013] As an optional embodiment, the positioning component includes a connecting fixing block, a connecting moving block, and an adjusting component. The connecting fixing block is disposed on the positioning main frame, and a first abutting surface abutting against the edge of the vehicle door is provided on one side of the connecting fixing block along the X-axis direction. A second abutting surface perpendicularly intersecting the first abutting surface is provided on one side of the connecting fixing block along the Y-axis direction. The adjusting component is disposed on the connecting fixing block and is movable and adjustable along the Y-axis direction. The connecting moving block is disposed at one end of the adjusting component and is distributed opposite to the second abutting surface. Adjusting the adjusting component along the Y-axis direction can drive the connecting moving block to move closer to the second abutting surface to clamp the vehicle door.

[0014] As an optional embodiment, the adjusting component includes an adjusting screw and a fixing nut. The connecting fixing block is provided with a through hole extending along the Y-axis direction. The adjusting screw passes through the through hole, and the fixing nut is screwed onto the adjusting screw and located on one side of the connecting fixing block. The connecting moving block is disposed at the end of the adjusting screw and located on the other side of the connecting fixing block. The fixing nut can abut against the connecting fixing block so that the connecting moving block can be kept in a clamped state.

[0015] As an alternative, the first abutting surface, the second abutting surface, the third abutting surface on the positioning part for abutting the outer side of the door, and the fourth abutting surface on the positioning block for abutting the front hood are all configured as outwardly convex arc shapes.

[0016] As an optional embodiment, the second detection block includes a second detection section, a third detection section, and a fourth detection section. The gap between the fourth detection section and the side rounded corner of the front hood, the gap between the second detection section and the middle rounded corner of the front hood, and the gap between the third detection section and the portion of the front hood between the side rounded corner and the middle rounded corner constitute the second gap.

[0017] As an optional solution, a fixing component is also included, which is disposed on the positioning main frame and is used to clamp the door along the Y-axis direction.

[0018] As an optional solution, a clamping assembly is also included, which is disposed on the positioning main frame and is capable of clamping and connecting with the vehicle body.

[0019] As an optional solution, the positioning component, the positioning detection element, the first detection block, the positioning block, and the second detection block are all mounted on the positioning main frame via connecting components. The positioning component, the positioning detection element, the first detection block, the positioning block, and the second detection block can all be adjusted along the X-axis, the Y-axis, and the Z-axis via the corresponding connecting components.

[0020] As an optional embodiment, each of the connecting components includes a first connecting block and a second connecting block. The first connecting block is connected to the positioning main frame, and the second connecting block is connected to the first connecting block. The positioning component, the positioning detection element, the first detection block, the positioning block, and the second detection block are connected to the corresponding second connecting block. Adjustment shims are provided between the first connecting block and the positioning main frame, between the second connecting block and the first connecting block, and between any one of the positioning component, the positioning detection element, the first detection block, the positioning block, and the second detection block and the corresponding second connecting block.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0043] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components.

[0044] In the description of this invention, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0045] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0046] like Figures 1-7 As shown, this embodiment of the invention provides a positioning device for positioning a vehicle door 100 and a hood 200. Before the fenders are assembled, the positioning device first positions the door 100 and the hood 200 to ensure accurate installation. Then, the fenders are installed, ensuring accurate fit between the fenders and the door 100, the hood 200, and the A-pillar 300. It should be noted that the A-pillar 300 is a fixed, non-adjustable structure on the vehicle; therefore, the door 100 needs to be adjusted to ensure accurate relative positioning between the door 100 and the A-pillar 300.

[0047] The positioning device includes a positioning main frame 1, a positioning component 2, a positioning detection element 3, and a first detection block 4. The positioning component 2, the positioning detection element 3, and the first detection block 4 are all mounted on the positioning main frame 1. The positioning component 2 can abut against the edge of the door 100 along the X-axis and can also clamp onto the door 100 along the Y-axis. The positioning detection element 3 includes a positioning part 31 and a first detection part 32 connected to each other. The positioning part 31 can be positioned on the outer surface of the door 100 along the Z-axis. The positioning part 31 and the positioning component 2 enable the positioning device to be positioned and connected to the door 100. After the positioning device is positioned and connected to the door 100, a first gap 1 is formed between the first detection part 32 and the edge of the door 100. 0. A second gap 20 is formed between the first detection block 4 and the A-pillar 300 of the vehicle. The first gap 10 and the second gap 20 are used to provide a basis for the adjustment of the door 100. When the positioning device is installed on the door 100, the first gap 10 between the first detection part 32 and the edge of the door 100 can be made to meet the set requirements first, and then the second gap 20 can be checked to see if it meets the design requirements. If it does not meet the requirements, the door 100 can be adjusted to make the second gap 20 meet the design requirements to ensure that the relative position of the door 100 and the A-pillar 300 is accurate.

[0048] The positioning device also includes a positioning block 5 and a second detection block 6, both of which are mounted on the positioning main frame 1. After the door 100 is adjusted to meet the requirements of the first gap 10 and the second gap 20, the hood 200 is then brought into contact with the positioning block 5, forming a third gap 30 between the hood 200 and the second detection block 6. This third gap 30 provides a basis for adjusting the hood 200. While the hood 200 is being adjusted, the door 100 is already adjusted, and its position is fixed, thus fixing the position of the positioning device. With the hood 200 in contact with the positioning hole, the hood 200 is adjusted to meet the design requirements of the third gap 30, thus completing the adjustment of the hood 200.

[0049] This positioning device can position the door 100 and the hood 200 before the fender is assembled, so that the installation positions of the door 100 and the hood 200 are accurate, ensuring the fast and accurate installation of the fender, avoiding frequent adjustments during the installation of the fender, and improving the installation efficiency of the fender.

[0050] In this embodiment, the first detection block 4 and the second detection block 6 are both fender contouring aids. By setting the first detection block 4 and the second detection block 6 as structural components with the same outline as the fender, the actual assembly state of the fender can be accurately simulated, so as to make precise adjustments to the door 100 and the hood 200.

[0051] In order to accurately determine the position of the positioning part 31 on the outer side of the door 100, when determining the position of the positioning part 31 on the outer side of the door 100, the upper end surface 321 of the first detection part 32 along the Z-axis direction can be aligned with the corresponding position on the outer side of the door 100 (i.e., the upper bending position of the outer side of the door 100). That is, the upper end surface 321 of the first detection part 32 is set as a contoured surface with the same shape as the upper bending position of the outer side of the door 100. When the upper end surface 321 of the first detection part 32 is aligned with the upper bending position of the outer side of the door 100, that is, the position of the positioning part 31 abutting against the outer side of the door 100 is the accurate position, and the positioning component 2 can clamp the door 100 to achieve positioning.

[0052] like Figures 4-6The positioning component 2 includes a connecting fixing block 21, a connecting moving block 22, and an adjusting component. The connecting fixing block 21 is mounted on the positioning main frame 1, and one side of the connecting fixing block 21 along the X-axis has a second abutment surface 212 that intersects the first abutment surface 211 perpendicularly. The adjusting component is mounted on the connecting fixing block 21 and is movable and adjustable along the Y-axis. The connecting moving block 22 is located at one end of the adjusting component and is distributed opposite to the second abutment surface 212. During installation, the edge of the door 100 abuts against the first abutment surface 211. Adjusting the adjusting component along the Y-axis can move the connecting moving block 22 closer to the second abutment surface 212 to clamp the door 100 between the second abutment surface 212 and the connecting moving block 22. The operation is simple and convenient.

[0053] Furthermore, the adjusting component includes an adjusting screw 23 and a fixing nut 24. A through hole extending along the Y-axis is provided on the connecting fixing block 21. The adjusting screw 23 passes through the through hole, and the fixing nut 24 is screwed onto the adjusting screw 23 and located on one side of the connecting fixing block 21. A connecting moving block 22 is located at the end of the adjusting screw 23 and on the other side of the connecting fixing block 21. Rotating the fixing nut 24 adjusts its position on the adjusting screw 23. The fixing nut 24 abuts against the connecting fixing block 21, keeping the connecting fixing block 21 in a clamped state. That is, by adjusting the nut, the adjusting screw 23 can move the connecting moving block 22 closer to or further away from the second abutment surface 212, thereby clamping or releasing the car door 100.

[0054] The first abutment surface 211, the second abutment surface 212, the third abutment surface 311 on the positioning part 31 for abutting with the door 100, and the fourth abutment surface 51 on the positioning block 5 for abutting with the front hood 200 are all designed to be outwardly convex arc-shaped. By setting the arc shape, the matching accuracy can be improved.

[0055] Refer to Figure 4 In this embodiment, since the area to be detected on the front hood 200 is relatively large, the second detection block 6 includes a second detection part 61, a third detection part 62, and a fourth detection part 63. The gap between the fourth detection part 63 and the side rounded corner of the front hood 200, the gap between the second detection part 61 and the middle of the front hood 200, and the gap between the third detection part 62 and the portion of the front hood 200 between the side rounded corner and the middle rounded corner constitute the second gap 20. This structural design allows for more precise adjustment of the front hood 200. In this embodiment, the fourth detection part 63 is a separate component, while the second detection part 61 and the third detection part 62 are interconnected to form a single component.

[0056] like Figure 1As shown, to improve the installation accuracy of the door 100 and the positioning device in the Y-axis direction, the positioning device also includes a fixing component 7. The fixing component 7 is disposed on the positioning main frame 1 and is positioned below the positioning component 2 along the Z-axis direction. The fixing component 7 can clamp the door 100 along the Y-axis direction. Specifically, the structural principle of the fixing component 7 is the same as that of the positioning component 2, and will not be repeated here. It should be noted that the fixing component 7 only needs to clamp the lower part of the door 100 in the Y-axis direction, and it is not necessary for the edge of the door 100 to abut against the fixing component 7 in the X-axis direction.

[0057] To ensure the positioning device is securely installed and to prevent it from falling off the door 100, such as... Figure 5 As shown, the positioning device also includes a clamping assembly 8, which is mounted on the positioning main frame 1 and can be clamped to the vehicle body to connect the positioning device to the vehicle body, thereby improving the installation stability of the positioning device. Specifically, an L-shaped connecting plate is provided on the vehicle body, and the vertical plate of the L-shaped connecting plate is fixedly connected to the vehicle body. The clamping assembly 8 includes a clamp 81, a lower clamp 82, and an upper clamp 83. The clamp 81 is fixedly mounted on the positioning main frame 1, the lower clamp 82 is fixed to the end of the clamp 81, and the upper clamp 83 is fixedly mounted on the positioning main frame 1 and corresponding to the lower clamp 82. Pressing the handle of the clamp 81 moves the lower clamp 82 closer to the upper clamp 83, so that the horizontal plate of the L-shaped connecting plate is clamped between the upper clamp 83 and the lower clamp 82, making operation convenient. The clamp 81 is a standard part, and its working principle is common knowledge and will not be described in detail here. To avoid the screws on the horizontal plate of the L-shaped connecting plate, the lower clamp 82 is designed with a U-shaped structure.

[0058] To make the positioning device structure adjustable, the positioning component 2, positioning detection component 3, first detection component, positioning block 5 and second detection block 6 are all set on the positioning main frame 1 through the connecting component 9. The positioning component 2, positioning detection component 3, first detection block 4, positioning block 5 and second detection block 6 can all be adjusted along the X-axis, Y-axis and Z-axis directions through the corresponding connecting component 9 to improve the accuracy of the positioning device and make the positioning device applicable to different vehicle models.

[0059] Furthermore, each connecting component 9 includes a first connecting block 91 and a second connecting block 92. The first connecting block 91 is connected to the positioning main frame 1, and the second connecting block 92 is connected to the first connecting block 91. The positioning component 2, the positioning detection component 3, the first detection block 4, the positioning block 5, and the second detection block 6 are connected to the corresponding second connecting block 92. Adjusting shims 93 are provided between the first connecting block 91 and the positioning main frame 1, between the second connecting block 92 and the first connecting block 91, and between any one of the positioning component 2, the positioning detection component 3, the first detection block 4, the positioning block 5, and the second detection block 6 and the corresponding second connecting block 92.

[0060] Specifically, such as Figure 7 As shown, taking positioning component 2 as an example, the first connecting block 91 is connected to the positioning main frame 1 along the Y-axis direction, the second connecting block 92 is disposed on the first connecting block 91 along the Z-axis direction, and the connecting fixing block 21 of positioning component 2 is disposed on the second connecting block 92 along the X-axis direction. Adjusting shims 93 are provided between the first connecting block 91 and the positioning main frame 1 to achieve adjustment of positioning component 2 along the Y-axis direction. Adjusting shims 93 are provided between the second connecting block 92 and the first connecting block 91 to achieve adjustment of positioning component 2 along the Z-axis direction. Adjusting shims 93 are provided between the connecting fixing block 21 and the second connecting block 92 of positioning component 2 to achieve adjustment of positioning component 2 along the X-axis direction. It can be understood that the number and thickness of the adjusting shims 93 can be set according to actual conditions.

[0061] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
