Description

Technical Field

[0001] This application relates to the field of vehicle body assembly technology, and in particular to an auxiliary tooling, assembly system and production line. Background Technology

[0002] The information provided in this section is for the purpose of generally presenting the background of this disclosure. To the extent described in this section, the work of the currently named inventors and aspects of the description that may not constitute prior art at the time of filing are neither explicitly nor implicitly considered to be prior art of this disclosure.

[0003] For conventional models, the hood and fenders are assembled and adjusted on the adjustment line using assembly templates. The fenders are installed first, followed by the hood. The dimensional chain is transferred sequentially from the rear door, front door, fenders, and hood. Typically, when assembling the fenders, the front door is used as a reference and a wraparound or integral template is used for assembly. When assembling the hood, the assembled fenders must be used as a reference and the template is used again for assembly.

[0004] Since the hood assembly requires the fender as a reference, the fender fixture must be assembled first, then removed from the fender fixture before the hood fixture is placed in for hood assembly. Furthermore, the fender assembly fixture has sliding rails or crossbeams to ensure alignment in the vehicle's width direction, completely overlapping the rear of the hood in space. If the hood is assembled directly, it will completely interfere with the template in the middle and rear, making further assembly impossible and removal impossible. Therefore, two different templates must be set up at different assembly stations to assemble the fender and hood separately. The assembly operations at different stations, and the disassembly and positioning of the templates, directly lead to low assembly efficiency. Moreover, due to the complexity of the positioning chain, the direct accumulation of assembly errors results in unpredictable assembly errors in the final fit between the hood and fender, reducing assembly accuracy and affecting the normal delivery of the assembly operation. Summary of the Invention

[0005] In view of the deficiencies in the prior art, this application provides an auxiliary tooling, assembly system and production line to solve the problem that the hood and fender cannot be installed at the same work station in the prior art.

[0006] The above-mentioned objectives of this application are mainly achieved through the following technical solutions:

[0007] An auxiliary tooling for installing a detachable hood and fender, the auxiliary tooling comprising a first mounting bracket and a second mounting bracket that are detachably connected.

[0008] The first mounting bracket is used to fix it to the vehicle body and is arranged along the width of the vehicle body. The first mounting bracket is provided with a first positioning member for positioning in conjunction with the door, so as to position the end of the fender near the door in the length and width directions of the vehicle body.

[0009] The second mounting bracket is provided with a second positioning component for positioning the engine cover and a third positioning component for positioning the fender. The second mounting bracket and the first mounting bracket are detachably connected by a connector so that the second positioning component and the third positioning component are positioned based on the first positioning component, and at the same time, the engine cover and the fender are positioned.

[0010] In an optional embodiment, the auxiliary tooling further includes a plurality of reference members, which are fixedly disposed at intervals on the second mounting bracket and can extend into the gap between the hood and the fender. The reference members are configured such that when the hood is rotated onto the second mounting bracket and positioned by the second positioning member, the reference members are located around the hood.

[0011] In an optional embodiment, two first positioning members are provided and are respectively arranged corresponding to the two fenders. A connecting rod is provided between the two first positioning members so that the two first positioning members move closer or further away from each other in the width direction of the vehicle body.

[0012] In an optional embodiment, the first positioning member includes a first positioning plate and a first positioning block. The first positioning plate can be inserted between the fender and the door along the width direction of the vehicle body, and the first positioning block can simultaneously abut against the fender and the door along the length direction of the vehicle body.

[0013] In an optional embodiment, the second positioning member includes at least two second positioning posts, which extend into the positioning holes of the hood and are movably connected to the second mounting bracket to move and adjust the hood in the length and width directions of the vehicle body.

[0014] In an optional embodiment, the third positioning element includes a third positioning block and a third positioning clamp respectively arranged corresponding to the fender. The third positioning block can cooperate with the positioning hole of the fender along the height direction of the vehicle body, and the third positioning clamp can be on the inner wall and outer wall of the fender.

[0015] In an optional embodiment, the connector is provided with at least two sets, each set of the connector including a locking pin and two sets of overlapping sections, the overlapping sections respectively fixingly connecting the first mounting bracket and the second mounting bracket, the locking pin can pass through both sets of overlapping sections at the same time to connect and position the first mounting bracket and the second mounting bracket.

[0016] In an optional embodiment, the first mounting bracket and the second mounting bracket are respectively provided with a support portion for mounting on the vehicle body.

[0017] An assembly system comprising the aforementioned auxiliary tooling.

[0018] A production line comprising the assembly system described above.

[0019] Compared with the prior art, the advantages of this application are:

[0020] The auxiliary tooling in this application is used to install a separate hood and fender. The auxiliary tooling includes a detachably connected first mounting bracket and a second mounting bracket. The first mounting bracket is fixed to the vehicle body and arranged along the width of the vehicle body. The first mounting bracket has a first positioning element for positioning in conjunction with a door, thereby positioning the end of the fender near the door in the length and width directions of the vehicle body. The second mounting bracket has a second positioning element for positioning the hood and a third positioning element for positioning the fender. The second mounting bracket and the first mounting bracket are detachably connected by a connector, so that the second and third positioning elements use the first positioning element as a positioning base to simultaneously position the hood and the fender. In actual operation, the first and second mounting brackets are set on the vehicle body at one assembly station, and the positioning base is provided by the first positioning element's engagement with the door to maintain the fender's proximity to the door. One end is initially positioned along the length and width of the vehicle body. Then, the first and second mounting brackets are directly positioned using connectors, avoiding the accumulation of errors caused by using the fender as a positioning base, thus improving assembly accuracy. Then, the second and third positioning components on the second mounting bracket simultaneously position the hood and fender. After the hood and fender are positioned and assembled, the first and second mounting brackets are separated by operating the connectors. The first and second mounting brackets can then be separated and removed in different directions within the gap between the separable hood and fender. In the same workstation, with a stable positioning base, the installation accuracy and efficiency of the fender and hood are improved. Moreover, the auxiliary tooling only needs to be positioned and assembled with the vehicle body once and removed after the hood and fender are installed, reducing the repeated disassembly and reassembly procedures and workstation changes, thus improving operational reliability.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is intended to aid in understanding the invention, but does not constitute a limitation thereof. The specific structural and functional details disclosed herein are merely for describing exemplary embodiments of the invention. However, the invention can be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0028] Figure 1 A schematic diagram of the auxiliary tooling is provided for the embodiments of this application; Figure 2 A partial top view of the auxiliary tooling is provided for the embodiments of this application; Figure 3 Appendix provided for embodiments of this application Figure 1 A magnified view of a portion of point A in the middle; Figure 4 This application provides an installation diagram of the auxiliary tooling during operation.

[0029] like Figure 1 , Figure 2 and Figure 4As shown, an auxiliary tooling is used to install a detachable hood 401 and fender 402. The auxiliary tooling includes a first mounting bracket 100 and a second mounting bracket 200 that are detachably connected. At the assembly station, the hood 401 and fender 402 are positioned and installed as a whole by the first mounting bracket 100 and the second mounting bracket 200. After the positioning and assembly of the hood 401 and fender 402 are completed, the first mounting bracket 100 and the second mounting bracket 200 can be disassembled and then separated from the vehicle body so that other assembly operations can be performed at subsequent work stations.

[0030] It should be noted that the separate hood 401 and fender 402 have a pre-reserved assembly gap for decorative parts. In other words, the hood 401 and fender 402 originally have adjacent matching edges, and the fit between these edges reflects the assembly precision. When the edges of the hood 401 and fender 402 are arranged adjacently, the assembly precision between the hood 401 and fender 402 can be further adjusted by comparing their relative positions during the positioning and installation of the hood 401. In other words, when uncontrollable errors occur at different workstations, manual confirmation and active adjustment are required at the next assembly workstation to improve the uniformity of the assembly gaps on a single vehicle body and reduce errors. However, this can also lead to unpredictable differences in the assembly effect between different vehicle bodies, making it difficult to control the overall consistency.

[0031] like Figure 2 As shown, however, a gap is provided between the separate hood 401 and fender 402 for installing decorative parts. In this state, the edges of the hood 401 and fender 402 cannot be manually compared and adjusted when assembling the hood 401. Consequently, on this model, the errors caused by assembly at different workstations and on different jigs are even more difficult to detect in advance, and these errors can only be reflected in the final assembly stage. This makes it difficult to improve assembly accuracy, difficult to confirm and adjust in a timely manner, increases the difficulty of assembly operations, and also has a greater possibility of repetitive work, which has a significant impact on vehicle uniformity and ultimately affects the user experience in the market.

[0032] The first mounting bracket 100 is used to fix it to the vehicle body and is arranged along the width of the vehicle body. The first mounting bracket 100 is provided with a first positioning member 101 for positioning in conjunction with the door, so as to position the fender 402 near the door in the length and width directions of the vehicle body. The first positioning member 101 is used to position the first mounting bracket 100 at the target position with the door as the positioning base, and to maintain the positioning state and reference of the first mounting member. That is, the first positioning member 101 and the door are used to provide a positioning base for the fender 402 located on both sides of the hood 401 by cooperating with the door in the length and width directions of the vehicle body. Since the installation position of the fender 402 needs to be positioned and assembled in the entire space, positioning one end of the fender 402 first can maintain the expected relative gap between the fender 402 and the door in the length of the vehicle body, and in the width of the vehicle body, the fender 402 and the door can achieve the set body streamline with the expected surface difference.

[0033] The second mounting bracket 200 is provided with a second positioning member 201 for positioning the engine cover 401 and a third positioning member 203 for positioning the fender 402. The second mounting bracket 200 and the first mounting bracket 100 are detachably connected by a connector so that the second positioning member 201 and the third positioning member 203 use the first positioning member 101 as the positioning base to simultaneously position the engine cover 401 and the fender 402. After the first positioning member 101 positions the fender 402 near the door, the second positioning member 201 and the third positioning member 203 on the second mounting bracket 200 can simultaneously provide positioning for the engine cover 401 and overall positioning for the fender 402. Therefore, when assembling the engine cover 401, it is not necessary to adjust the fit between the engine cover 401 and the edge of the fender 402, thereby improving the accuracy and efficiency of the operation.

[0034] like Figure 4As shown, in an optional embodiment, the working principle of the auxiliary tooling in this application is as follows: When installing the separate hood 401 and fender 402, the auxiliary tooling includes a detachably connected first mounting bracket 100 and a second mounting bracket 200. The first mounting bracket 100 is used to fix to the vehicle body and is arranged along the width of the vehicle body. The first mounting bracket 100 is provided with a first positioning member 101 for positioning in conjunction with the door, so as to position the end of the fender 402 near the door in the length and width directions of the vehicle body. The second mounting bracket 200 is provided with a second positioning member 101 for positioning the hood 401. The positioning component 201 and the third positioning component 203 for positioning the fender 402 are provided. The second mounting bracket 200 and the first mounting bracket 100 are detachably connected by a connector, so that the second positioning component 201 and the third positioning component 203 use the first positioning component 101 as the positioning base, and simultaneously position the hood 401 and the fender 402. In actual operation, the first mounting bracket 100 and the second mounting bracket 200 are set on the vehicle body at one assembly station, and positioning is provided by the cooperation of the first positioning component 101 with the door. The first mounting bracket 100 and the second mounting bracket 200 are initially positioned along the length and width of the vehicle body, with the fender 402 near the door as the base. Then, the first mounting bracket 100 and the second mounting bracket 200 are directly positioned using connectors, avoiding the accumulation of errors caused by using the fender 402 as the positioning base and improving assembly accuracy. Next, the second positioning component 201 and the third positioning component 203 on the second mounting bracket 200 simultaneously position the hood 401 and the fender 402. After the hood 401 and fender 402 are positioned and assembled, the first mounting bracket 100 is separated by operating the connectors. The first mounting bracket 100 and the second mounting bracket 200 can be separated and dismantled in different directions within the gap between the split hood 401 and the fender 402. On the same work station, with a stable positioning base, the installation accuracy and efficiency of the fender 402 and the hood 401 are improved. The auxiliary tooling only needs to be positioned and assembled with the vehicle body once, and can be removed after the hood 401 and the fender 402 are installed. This reduces the operation procedures of repeated disassembly and reassembly and changing work stations, and improves the reliability of operation.

[0035] It should be further explained that there is a pre-existing gap between the separate hood 401 and fender 402 for the installation of decorative parts. Originally, the hood 401 and fender 402 had adjacent matching edges, and the fit between these edges reflected the assembly precision. The separate hood 401 and fender 402 also have a gap for installing decorative parts. In this state, the edges of the hood 401 and fender 402 cannot be manually compared and adjusted when assembling the hood 401. In other words, the relative positional relationship between the hood 401 and fender 402 cannot be obtained through manual observation, or the gap information observed manually cannot contribute to the installation precision of the hood 401 and fender 402.

[0036] On this model, the errors caused by assembling at different workstations and on different jigs can only be reflected in the final assembly stage, which makes it difficult to improve assembly accuracy and to confirm and adjust in a timely manner.

[0037] like Figure 1 , Figure 2 As shown, in an optional embodiment, the auxiliary tooling further includes a plurality of reference members 204, which are fixedly disposed at intervals on the second mounting bracket 200 and can extend into the gap between the hood 401 and the fender 402. The reference members 204 are configured such that when the hood 401 is rotated onto the second mounting bracket 200 and positioned by the second positioning member 201, the reference members 204 are located around the hood 401.

[0038] By arranging the reference pieces 204 on the second mounting bracket 200, when the cover 401 is positioned and assembled on the second mounting bracket 200, the cover 401 is first positioned by the second positioning piece 201. At the same time, the multiple reference pieces 204 surrounding the cover 401 have a more flexible reference gap with the edge of the cover 401. Thus, by adjusting the relative position of the cover 401 and the reference pieces 204, the cover 401 can be kept in a more precise adjustment state.

[0039] When the engine cover 401 needs to be adjusted, since the adjustment requirement of the engine cover 401 is not completely aligned with the length or width of the vehicle body, the adjustment amount of the engine cover 401 can be obtained through multiple positional data between the engine cover 401 and multiple reference parts 204, thereby realizing the adjustment action of the second positioning part 201, making the operation faster and more precise.

[0040] In actual operation, the gap between the hood 401 and the fender 402, as well as the data obtained from the pre-assembly of the decorative parts installed in the gap, can be used to obtain different reference data between the edge of the hood 401 and different reference parts 204. When installing the hood 401, the reference data is verified. This verification process can be obtained by the sensors on the reference parts 204 or by setting up a vision detection component. When positioning the hood 401 on the second positioning part 201, the hood 401 can directly obtain adjustment data in the dimensions of angle, distance, etc. in the length and width directions of the vehicle body, further improving the assembly accuracy. Moreover, after obtaining the above data, the data can be used for adjustment reference when performing assembly operations on different vehicle bodies, improving the accuracy and overall consistency of vehicle assembly.

[0041] like Figure 1 , Figure 2 As shown, in an optional embodiment, there are two first positioning members 101, which are respectively arranged corresponding to the two fenders 402. A connecting rod 104 is provided between the two first positioning members 101 so that the two first positioning members 101 simultaneously move closer or further away in the width direction of the vehicle body.

[0042] Two first positioning components 101 are arranged on both sides of the vehicle body width direction, corresponding to the two fenders 402. After the first positioning components 101 are installed, the first mounting bracket 100 can maintain a more accurate positioning base with the first positioning components 101 on both sides of the vehicle body, and both fenders 402 can maintain a stable relative mounting base with the door. The two first positioning components 101 can move towards or away from each other in the width direction of the vehicle body through the connecting rod 104, thereby maintaining the first positioning components 101 in a stable position in the width direction of the vehicle body, maintaining the assembly accuracy of the first mounting bracket 100, and providing the accuracy of the mounting base of the second mounting bracket 200.

[0043] Specifically, the connecting rod 104 includes two drive rods that are respectively connected to the first positioning member 101. The end of the drive rod away from the first positioning member 101 is symmetrically connected to the drive wheel, so that when the drive wheel rotates, it pulls the drive rod to drive the first positioning member 101 to move synchronously, thereby improving the ease of operation.

[0044] like Figure 1 , Figure 2 and Figure 3As shown, in an optional embodiment, the first positioning member 101 includes a first positioning plate 102 and a first positioning block 103. The first positioning plate 102 can be inserted between the fender 402 and the door along the width direction of the vehicle body, and the first positioning block 103 can simultaneously abut against the fender 402 and the door along the length direction of the vehicle body.

[0045] The first positioning plate 102 is inserted between the fender 402 and the door. The thickness of the first positioning plate 102 can be set so that the fender 402 is positioned on one side of the door at a set interval. In other words, the thickness of the first positioning plate 102 can quickly and accurately control the size of the gap between the fender 402 and the door. The first positioning block 103 is attached to the door and the fender 402 respectively to keep the end of the fender 402 close to the door with a set surface difference to match the door, thereby improving the assembly accuracy.

[0046] In an optional embodiment, the second positioning member 201 includes at least two second positioning posts 202, which are used to extend into the positioning holes of the hood 401 and are movably connected to the second mounting bracket 200 to drive the hood 401 to move and adjust in the length and width directions of the vehicle body.

[0047] The second positioning post 202 cooperates with the positioning hole of the hood 401 to position the hood 401 in the length and width directions of the vehicle body. Moreover, the movable connection of the second positioning post 202 allows for more flexible adjustments when arranging the hood 401 or when the positioning position of the hood 401 needs to be adjusted, thus improving operability.

[0048] like Figure 1 , Figure 2 As shown, in an optional embodiment, the third positioning member 203 includes a third positioning block and a third positioning clamp respectively arranged corresponding to the fender 402. The third positioning block can cooperate with the positioning hole of the fender 402 along the height direction of the vehicle body, and the third positioning clamp can be on the inner wall and outer wall of the fender 402.

[0049] The third positioning block cooperates with the positioning hole of the fender 402. Specifically, the positioning block includes a first part extending into the positioning hole of the fender 402 and a second part abutting against the fender 402. The abutting of the second part provides height positioning, and the extension of the first part constrains the position of the fender 402 in the length and width directions of the vehicle body. The third positioning clamp holds the fender 402, providing stable positioning of the fender 402 with different profiles and ensuring the reliability of the fender 402 during assembly after positioning.

[0050] In an optional embodiment, the connector is provided with at least two sets, each set of the connector including a locking pin 301 and two sets of overlapping sections 302. The overlapping sections 302 are respectively fixedly connected to the first mounting bracket 100 and the second mounting bracket 200. The locking pin 301 can pass through both sets of overlapping sections 302 at the same time to connect and position the first mounting bracket 100 and the second mounting bracket 200.

[0051] The first mounting bracket 100 and the second mounting bracket 200 are precisely positioned in the length and width directions of the vehicle body by locking pin 301. After the installation of the hood 401 and the fender 402 is completed, the locking pin 301 is removed and the overlapping section 302 can be separated from each other. The first mounting bracket 100 and the second mounting bracket 200 can be removed separately after disassembly, which can quickly carry out subsequent vehicle assembly operations. Moreover, for this workstation, the auxiliary tooling can be set up by a set of disassembly and assembly equipment, avoiding the need to use multiple sets of equipment for repeated auxiliary operations in the vehicle assembly area.

[0052] In an optional embodiment, the first mounting bracket 100 and the second mounting bracket 200 are respectively provided with support parts for mounting on the vehicle body, maintaining the overall stability of the first mounting bracket 100 and the second mounting bracket 200, and the support parts can be arranged in an adaptive manner according to different vehicle models, making them highly adaptable.
