Description

Technical Field

[0001] This utility model belongs to the field of automotive assembly positioning aids technology, and more specifically, relates to a multi-functional positioning aid for the front bulkhead component of a body-in-white. Background Technology

[0002] The front bulkhead is a crucial assembly in the automotive body structure that separates the engine compartment from the passenger compartment, and is a core component of the front body. The front bulkhead cover is mounted between the left and right fenders, using positioning holes on the vehicle body for installation and positioning.

[0003] However, the following problems are likely to occur during assembly and subsequent operations: (1) The Y-axis dimension of the front cover plate is limited by the distance between the left and right fenders, and the X-axis dimension is limited by the front cover plate connector. The two are usually positioned separately, which can easily lead to error accumulation; (2) The front cover plate and the front cover plate connector are connected by welding. Welding deformation will cause deformation of the parts, resulting in increased error, which in turn affects the installation of the fenders and hood and subsequent surface difference control.

[0004] Therefore, there is an urgent need for a positioning tool for the front bulkhead components of a body-in-white, which can position the front bulkhead cover and the connecting parts of the left and right front bulkhead cover in one go, ensuring installation accuracy and controlling welding deformation. Utility Model Content

[0007] Furthermore, the front cover plate positioning component includes an extension rod, a front stop block, and a rear stop block.

[0008] Furthermore, the rear end of the extension rod is fixed at the middle of the top of the support beam, and its front end is located directly above the front cover plate; the front stop and the rear stop are respectively fixed at the bottom of the front end of the extension rod, and the two form a V-shaped structure to block and limit the front and rear ends of the middle of the front cover plate to prevent X-direction deformation and displacement during welding.

[0009] Furthermore, the left-side positioning mechanism includes a first left positioning pin and a second left positioning pin, which correspond to the first left positioning hole and the second left positioning hole respectively provided on the left front cover plate connector. The left front cover plate connector is positioned and fixed by inserting the first left positioning pin into the first left positioning hole and the second left positioning pin into the second left positioning hole.

[0010] Furthermore, the left-side positioning mechanism also includes a third left positioning pin and a fourth left positioning pin; the third left positioning pin corresponds to the third left positioning hole provided on the front cover plate, and the positioning of the left end of the front cover plate is completed by inserting the third left positioning pin into the third left positioning hole; the fourth left positioning pin corresponds to the fourth left positioning hole provided on the lower plate of the windshield glass, and the positioning of the left end of the support beam on the lower plate of the windshield glass is achieved by inserting the fourth left positioning pin into the fourth left positioning hole.

[0011] Furthermore, the right-side positioning mechanism includes a first right positioning pin and a second right positioning pin, which correspond to the first right positioning hole and the second right positioning hole respectively provided on the right front cover plate connector. The right front cover plate connector is positioned and fixed by inserting the first right positioning pin into the first right positioning hole and the second right positioning pin into the second right positioning hole.

[0012] Furthermore, the right-side positioning mechanism also includes a third right positioning pin and a fourth right positioning pin; the third right positioning pin corresponds to the third right positioning hole provided on the front cover plate, and the positioning and fixing of the right end of the front cover plate is completed by inserting the third right positioning pin into the third right positioning hole; the fourth right positioning pin corresponds to the fourth right positioning hole provided on the lower plate of the windshield glass, and the positioning of the right end of the support beam on the lower plate of the windshield glass is achieved by inserting the fourth right positioning pin into the fourth right positioning hole.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0034] like Figure 1-7As shown, this utility model provides a multi-functional positioning aid for the front bulkhead component of a white body, including a central positioning mechanism 1, a left-side positioning mechanism 2, a right-side positioning mechanism 3, and a support beam 4. The central positioning mechanism 1 is fixedly disposed in the middle of the support beam 4, and includes a front bulkhead upper cover plate positioning component 11 and a support block. The front bulkhead upper cover plate positioning component 11 limits the front and rear ends of the front bulkhead upper cover plate 7 to prevent its X-axis displacement and deformation. The support block is placed on top of the lower windshield glass plate 8 to determine the height position of the support beam 4 in the Y-axis direction. The left-side positioning mechanism 2 is fixedly disposed at the left end of the support beam 4, and includes multiple left positioning pins. The angle and position of the multiple left positioning pins are adjusted by corresponding positioning blocks, so that the multiple left positioning pins are inserted into the left front bulkhead upper cover plate connector 5 and the front bulkhead... The left positioning pins are inserted into the corresponding left positioning holes on the upper cover plate 7 and the lower plate of the windshield glass 8. The right positioning mechanism 3 is fixedly installed at the right end of the support beam 4 and includes multiple right positioning pins. The angle and position of the multiple right positioning pins are adjusted by corresponding positioning blocks so that the multiple left positioning pins are inserted into the corresponding right positioning holes on the right front upper cover plate connector, the front upper cover plate 7, and the lower plate of the windshield glass 8. The left positioning mechanism 2 and the right positioning mechanism 3 realize the Z-axis positioning of the front upper cover plate 7, and at the same time, the left front upper cover plate connector 5 and the right front upper cover plate connector 6 are positioned and rigidly supported. The positioning auxiliary tool of this utility model can simultaneously position and control multiple components and control the amount of welding deformation. This auxiliary tool can be reused, has low cost, and has significant effect.

[0035] like Figure 1-3 As shown in Figure 7, the central positioning mechanism 1 is used to position the middle part of the front cover plate 7, and it includes a front cover plate positioning component 11, a support block and an auxiliary handle.

[0036] The front cover plate positioning component 11 includes an extension rod 111, a front stop block 112, and a rear stop block 113. The rear end of the extension rod 111 is fixed at the top middle of the support beam 4, and its front end is located directly above the front cover plate 7. The front stop block 112 and the rear stop block 113 are respectively fixed at the bottom of the front end of the extension rod 111. The two form a V-shaped structure to block and limit the front and rear ends of the center of the front cover plate 7, preventing X-direction deformation and displacement during welding.

[0037] The support blocks support and position the support beam 4 to determine the position of the positioning aid in the Y direction, which facilitates the next positioning operation. The support blocks include a left support block 13 and a right support block 15, which are symmetrically and fixedly installed on both sides of the bottom center of the support beam 4. The left support block 13 and the right support block 15 are placed on the top of the lower plate 8 of the windshield glass, thereby determining the height position of the support beam 4 in the Y direction.

[0038] The auxiliary handle facilitates the movement of the positioning aid by the operator. It includes a left auxiliary handle 12 and a right auxiliary handle 14 that are symmetrically and fixedly located on both sides of the top center of the support beam 4. By holding the auxiliary handle, the operator can move the entire positioning aid more easily and accurately place it in the front part area to be positioned, reducing the difficulty of operation.

[0039] like Figure 3 As shown, the left-side positioning mechanism 2 precisely positions and fixes the relevant components on the left side of the front bulkhead. It includes a first left positioning pin 21, a second left positioning pin 22, a third left positioning pin 23, and a fourth left positioning pin 24, which are sequentially fixed to the left end of the support beam 4 via corresponding positioning blocks. The first left positioning pin 21 and the second left positioning pin 22 correspond to the first left positioning hole 501 and the second left positioning hole 502 respectively on the left front bulkhead upper cover plate connector 5. By adjusting the angle and position using the corresponding positioning blocks, the first left positioning pin 21 is pushed into the first left positioning hole 501, and the second left positioning pin 22 is pushed into the second left positioning hole 502, thereby positioning and fixing the left front bulkhead upper cover plate connector 5. The third left... The positioning pin 23 corresponds to the third left positioning hole 701 provided on the front upper cover plate 7. By adjusting the angle and position of the corresponding positioning block, the third left positioning pin 23 is pushed into the third left positioning hole 701 to complete the positioning and fixing of the left end of the front upper cover plate 7. The fourth left positioning pin 24 corresponds to the fourth left positioning hole 801 provided on the lower plate of the windshield glass. By adjusting the angle and position of the corresponding positioning block, the fourth left positioning pin 24 is pushed into the fourth left positioning hole 801, thereby realizing the positioning of the left end of the support beam 4 on the lower plate of the windshield glass. The welding stress is introduced into the lower plate of the windshield glass to offset it, so as to avoid the left end of the support beam 4 from being deflected when subjected to the welding stress of the left end of the left front assembly, thereby providing rigid support for the left end of the left front assembly.

[0040] The right-side positioning mechanism 3 precisely positions and fixes the relevant components on the right side of the front bulkhead. It includes a first right positioning pin 31, a second right positioning pin 32, a third right positioning pin 33, and a fourth right positioning pin 34, which are sequentially fixed to the right end of the support beam 4 via corresponding positioning blocks. The first right positioning pin 31 and the second right positioning pin 32 correspond to the first right positioning hole 601 and the second right positioning hole 602 respectively on the right front bulkhead upper cover plate connector 6. By adjusting the angle and position using the corresponding positioning blocks, the first right positioning pin 31 is pushed into the first right positioning hole 601, and the second right positioning pin 32 is pushed into the second right positioning hole 602, thereby positioning and fixing the right front bulkhead upper cover plate connector 6. The third right positioning pin 31... Positioning pin 33 corresponds to the third right positioning hole 702 provided on the front upper cover plate 7. By adjusting the angle and position with the corresponding positioning block, the third right positioning pin 33 is pushed into the third right positioning hole 702, thus completing the positioning and fixing of the right end of the front upper cover plate 7. The fourth right positioning pin 34 corresponds to the fourth right positioning hole 801 provided on the lower plate of the windshield glass. By adjusting the angle and position with the corresponding positioning block, the fourth right positioning pin 34 is pushed into the fourth right positioning hole 802, thereby realizing the positioning of the right end of the support beam 4 on the lower plate of the windshield glass. The welding stress is introduced into the lower plate of the windshield glass to offset it, avoiding the right end of the support beam 4 from shifting when subjected to the welding stress of the right front part, thus providing rigid support for the right end of the right front part.

[0041] When the positioning aid of this utility model is in operation, the operator holds the left auxiliary handle 12 and the right auxiliary handle 14 to move the positioning aid to the top of the lower plate 8 of the windshield glass, so that the fourth left positioning pin 24 is aligned and inserted into the fourth left positioning hole 801, and the fourth right positioning pin 34 is aligned and inserted into the fourth right positioning hole 802, until the left support block 13 and the right support block 15 contact the top of the lower plate 8 of the windshield glass, so that the support beam 4 is kept horizontal; the front cover plate 7 and the left front cover plate connector 5 and the right front cover plate connector 6 on both sides are installed in sequence; the middle part of the front cover plate 7 is inserted into the V-shaped structure formed by the front stop block 112 and the rear stop block 113, and the third left positioning pin 23 is inserted into the left positioning pin 701 at the left end, and the third right positioning hole 702 at the right end is inserted into the third right positioning hole 702. Insert the third right positioning pin 33 to complete the positioning and support of the front upper cover plate 7; insert the first left positioning pin 21 and the second left positioning pin 22 into the first left positioning hole 501 and the second left positioning hole 502 on the left front upper cover plate connector 5 respectively to complete the positioning and support of the left front upper cover plate connector 5; insert the first right positioning pin 31 and the second right positioning pin 32 into the first right positioning hole 601 and the second right positioning hole 602 on the right front upper cover plate connector 6 respectively to complete the positioning and support of the right front upper cover plate connector 6; after the front components are positioned and fixed, the next welding operation is carried out. The stress generated by welding is transmitted to the lower plate of the windshield glass 8 through the support beam 4 and the four left positioning pins 24 and the four right positioning pins 24 to offset it, ensuring the installation accuracy and controlling the welding deformation.

[0042] The positioning aid of this utility model can simultaneously position the front bulkhead components, greatly improving the installation accuracy. It can complete the coordinated positioning of the front bulkhead top cover, the left / right front bulkhead top cover connectors and the lower windshield glass in one go, avoiding the error accumulation caused by traditional separate positioning. The central positioning mechanism restricts the X-direction displacement of the front bulkhead top cover, and the left / right positioning mechanism achieves Z-direction positioning, ensuring the accuracy of component installation position in multiple dimensions, while providing rigid support for the front bulkhead components.

[0043] The positioning aid of this utility model can effectively control welding deformation and ensure the structural stability of the component: the positioning aid transmits the stress generated during the welding process to the lower plate of the windshield glass through the support beam to offset it, and avoids the support beam from shifting due to welding stress; the positioning and fixing of the front part of the component by the left / right positioning mechanism and the limiting of the front upper cover plate by the middle positioning mechanism can reduce the deformation displacement of the component during welding and significantly reduce the amount of welding deformation.

[0044] The positioning aid of this utility model is reusable and easy to operate, reducing the cost of use. The overall structure of the aid is durable and supports repeated placement of the front part of the body-in-white for positioning operations without frequent replacement. It is equipped with an auxiliary handle, which makes it easy for operators to move and accurately place the aid, reducing the difficulty of operation. Compared with positioning methods that require multiple adjustments or one-time use, it effectively reduces time and material costs.
