Description

Technical Field

[0001] The utility model relates to auxiliary tooling for assembling between the B-pillar position and the floor of the left and right side wall assemblies of the white body, and specifically relates to an auxiliary tooling for on-vehicle correction of the B-pillar of the white body of an automobile, belonging to the technical field of automobile parts installation. Background Art

[0002] The Turbo Daily series is a classic model produced by Nanjing Iveco Automobile Co., Ltd. The former Turbo Daily is a car brand - Deyi. The initial design of the white body roof is a fiberglass top bonding form. The roof crossbeam assembly at the B and C pillar positions adopts a bolt assembly process before the fiberglass roof is bonded.

[0003] With the growing automotive market, consumers' demands for vehicle safety are also increasing. To meet market demand and enhance product safety, the roof of the Turbo Daily series has been upgraded from a fiberglass roof to a sheet metal roof structure. The process involves first integrating the roof crossbeam assembly at the B- and C-pillars with the sheet metal roof (forming a framework to ensure consistent quality during transportation), followed by assembly and welding with the body-in-white.

[0004] Fiberglass reinforced plastic (FRP), also known as GFRP, is a fiber-reinforced plastic that, when formed into a single piece, exhibits superior toughness but limited rigidity. However, when a sheet metal roof forms a frame, its overall rigidity is significantly superior to that of a fiberglass roof. Therefore, strict control measures are required during the assembly and integration of the sheet metal roof and the body-in-white to ensure the proper clearance between the left and right sidewalls.

[0005] According to the applicant's understanding, due to the lack of assembly and connection of the roof crossbeams at the B and C pillars before the assembly of the automobile roof, it is difficult to improve the opening size accuracy of the left and right side walls of the white body before the assembly of the roof, and the assembly of the roof is also not so easy; at this time, whether changing the white body structure or transforming the existing welding production line will bring a huge investment, so it is necessary to consider using a white body B-pillar on-vehicle correction auxiliary tooling to meet the assembly and production needs under the design and mass production status, thereby greatly reducing the investment cost.

DETAILED DESCRIPTION

[0025] The vehicle body-in-white B-pillar on-vehicle correction auxiliary tooling provided in the first embodiment is as follows: Figure 1 — Figure 7 As shown, first combine Figure 2 : It includes a profile-shaped connecting rod g, at least one side of which is evenly covered with a groove go; the upper side wall a of the B-pillar has a positioning hole, which is a hole in the vehicle body on the upper side wall a of the B-pillar. The two ends of the connecting rod g are connected with a reference fixing component 1 and a positioning component 2, such as Figure 3 As shown. Combined Figure 1 、 Figure 3 、 Figure 6 : The vehicle floor b and the upper side wall a of the B-pillar are connected accordingly through the reference fixing component 1 and the positioning component 2, so that the connecting rod g, the upper side wall a of the B-pillar, and the vehicle floor b form a triangular frame pattern, and at the same time the connecting rod g supports the vehicle body to assist in the assembly of the vehicle roof and the white body and ensure the dimensional accuracy of the gap between the left and right side walls of the vehicle.

[0026] The specific composition and connection of the above-mentioned reference fixing component 1 are as follows: Figure 4: It mainly includes a reference pin seat 10, a positioning pin 11 and its anti-loosening nut 12. The reference pin seat 10 is connected as a whole by a reference plate 101 and a flap 102. An obtuse angle is formed between the flap 102 and the reference plate 101. The reference plate 101 is fixed to the vehicle floor b through the positioning pin 11 and the anti-loosening nut 12. The flap 102 is supported and attached to the lower end of the connecting rod g; when the flap 102 is attached to the lower end of the connecting rod g, it is locked at the same time by two bolts and two spring nuts m in the groove go; then, limit blocks 103 are added on the two outer surfaces of the flap 102 to connect with the connecting rod g and form a clamping tendency for the connecting rod g, thereby further enhancing the stability of the reference pin seat 10 when it is attached to the lower end of the connecting rod g.

[0027] The above positioning component 2 is specifically composed and connected, and its combination Figure 5 、 Figure 7 : It includes a latch seat 20, a latch 21, an adapter block 22 and a U-shaped card seat 23. The adapter block 22 is composed of a strip block 221 and a plate block 222. The plate block 222 and the strip block 221 are connected to each other longitudinally, transversely and at an obtuse angle. The strip block 221 is connected to the lower end of the front end of the latch seat 20 by two bolts and at least one adjustment pad 223. When working, the latch 21 passes through the latch seat 20 to the positioning hole a on the upper side wall of the B column on the rear end of the latch seat 20; the plate block 222 is connected to the lower end of the front end of the latch seat 20 by two bolts and at least one adjustment pad 223. An adjusting pad 223 and two spring nuts m in the groove go are locked together at the upper end of the connecting rod g, wherein each adjusting pad 223 has a corresponding clearance area 224 for the bolt to pass through. The above-mentioned adjusting pads 223 are standard parts. When necessary, the number of adjusting pads 223 can be increased or decreased to meet the dimensional error in the positioning assembly, so that the accuracy of the tooling can be further improved; the two side plates of the U-shaped holder 23 clamp the plate block 222 and the two side walls of the connecting rod g, and are fixed to the connecting rod g by bolts.

[0028] Combined with Figure 5: The latch 21 includes a latch rod 211, a limiting rod 212 and an unlocking button 213. A plurality of locking marbles 214 are distributed on the free end of the latch rod 211. A central through hole is provided in the latch seat 20 to ensure that the latch rod 211 passes through. A sliding groove 201 with an L-shaped cross section is provided on the outer wall of the latch seat 20. The sliding groove 201 is connected to the central through hole. At least one side of the limiting rod 212 is L-shaped. First, the L-shaped end of the limiting rod 212 is placed in the sliding groove 201 and fixedly connected to the latch rod 211 in the central through hole. Then, the limiting rod 212 is placed on the other side. One end is connected to the latch rod 211 outside the latch seat 20; the limiting rod 212 cooperates with the L-shaped sliding groove 201, and the locking marble 214 is driven to operate by operating the unlocking button 213. In this way, the latch seat 20 and the latch 21 are combined into a locking mechanism, and the sliding groove 201 becomes the movement trajectory of the limiting rod 212. When the latch rod 211 is inserted into the positioning hole a on the upper side wall of the B-pillar, the rear end surface of the latch seat 20 and the locking marble 214 are locked at the same time. When unlocking is required, the locking marble 214 is operated by the unlocking button 213, such as Figure 7 To improve the accuracy and precision of the latch 21, several sleeves 202 are mounted at the front and rear ends of the central through-hole of the latch seat 20. The sleeves 202 restrict the movement of the latch rod 211. Cover plates 203 are mounted at the front and rear central through-holes, each with a through-hole in the center to allow the latch rod 211 to pass through. At least one adjustment washer 204 is installed between the cover plates 203 and the central through-hole. The adjustment washer 204 is bolted to the front and rear ends of the latch seat 20 and simultaneously bolted to the front and rear cover plates 203. The cover plates 203 seal the sleeves 202 within the latch seat 20, preventing them from slipping. The insertion depth of the latch 21 is controlled by increasing or decreasing the number of adjustment washer 204 to ensure that the locking ball 214 on the latch 21 is locked in place.

[0029] In order to reduce weight to a greater extent, the connecting rod g is preferably made of aluminum and has a hollow center; the cross-section of the connecting rod g is square to ensure ease of use; however, in the above embodiment, the reference pin seat 10, the pin seat 20, the pin 21, the adapter block 22, the U-shaped seat 23, the adjustment gasket 204, the adjustment pad 223 and the limit block 103 are preferably made of rigid material to facilitate improving the accuracy and strength of the tooling.

[0030] This utility model primarily relies on a datum fixing assembly and a positioning assembly on the connecting rod to achieve precise assembly and connection of the B- and C-pillars without a top crossbar during the final assembly of the body-in-white. The datum fixing assembly primarily assists in part modeling and provides a manufacturing operation path, ensuring that the positioning of the parts requiring assembly on the body meets technical requirements. The positioning assembly primarily locates and locks the relevant parts, ensuring that the relative relationship between the positioned parts and the datum meets technical requirements.

[0031] The assembly process of the tool itself: first assemble the reference fixing component 1, combine Figure 4 : Assemble the positioning pin 11 and the anti-loosening nut 12 to the reference pin seat 10, then insert the spring nut m into the groove go of the connecting rod g, and then connect the assembled reference pin seat 10 with the spring nut m through the bolt, and finally assemble the two limit blocks 103 to the outer side of the reference pin seat. Then assemble the positioning assembly 2, combine Figure 5 : Assemble the sleeve 202 onto the latch seat 20, and then assemble the adjusting gasket 204 and the cover plate 203. After completion, insert the latch 21 into the sleeve 202 of the latch seat 20, and simultaneously insert one end of the limit rod 212 into the L-shaped sliding groove 201 of the latch seat 20, and the other end of the limit rod 212 is bolted to the latch rod 211, so as to form a locking mechanism; assemble the adapter block 22 and the adjusting gasket 223 onto the combined locking mechanism, and simultaneously insert the spring nut m into the groove go of the connecting rod g, and then connect the combined locking mechanism with the spring nut m by bolts, and finally assemble and limit the U-shaped bracket 23; because the adapter block 22 and the material-shaped connecting rod g are connected by bolts and spring nuts m, this connection is not sufficient to maintain the position stability of the adapter block 22, so it is necessary to assemble the U-shaped bracket 23 to limit the position stability of the adapter block 22.

[0032] The working principle of this utility model is: because there is no top crossbeam assembly connection process at the B and C pillar positions when the white body is assembled, such as Figure 1 As shown, the gap size at the upper part of the B and C pillars on the left and right sides of the vehicle body is unstable. Therefore, during the assembly of the body in white, the B-pillar auxiliary correction tool is installed on the vehicle. The auxiliary tool is used to lock the angle and size between the upper side wall a of the B-pillar and the vehicle floor b, and control the left and right dimensions of the B and C pillars on the left and right sides until the top cover assembly process, as shown in the figure. Figure 1 、 6 Then, combined with Figure 1 : After the top cover and the body in white are assembled, the top cover crossbeam on the top cover assembly is used to control the gap size between the left wall B-pillar and the right wall B-pillar. Finally, the tooling is removed after the top cover and the body in white are welded.

[0033] The process of using the auxiliary tooling for on-board correction of the B-pillar of the automobile body in white is as follows: during the overall assembly of the body in white, the auxiliary tooling is sent into the body of the vehicle, and the positioning pin 11 of the tooling reference fixing component 2 is inserted into the positioning pin hole of the reference pin seat 10 on the vehicle floor b corresponding to the position of the B-pillar of the body in white. The latch rod 212 of the positioning component 2 of the auxiliary tooling is further inserted into the positioning hole a on the upper side wall of the B-pillar of the body in white. The locking ball 214 on the latch rod 212 is observed to enter the positioning hole, and the rear end surface of the latch seat 20 is in close contact with the workpiece in the form of a positioning surface. The locked latch 21 cannot be pulled out after being subjected to force, which means it is qualified. The tooling is assembled into the body in white during the overall assembly of the body in white, and is transported and moved with the body in white to lock the relative size of the B-pillar position between the left and right side walls of the body in white. After the top cover assembly is welded to the body in white, it is disassembled and repeated in the previous link for recycling. The number of auxiliary tooling for on-board correction of the B-pillar of the body in white can be determined according to the number of workstations on the assembly line.

[0034] In addition, different car models can first select the most advantageous dimensions in the car to form a triangular frame structure, and select the positioning pin hole position of the positioning pin 11 on the vehicle floor b according to the positioning hole on the upper side wall a of the B-pillar. The production and use of this tool should first be explained: the positioning holes on the upper side wall a of the B-pillar and the positioning pin holes on the vehicle floor b used in the tool are both existing body holes on the vehicle body, and there is no need to open special holes separately; the positioning pin holes on the vehicle floor b, the positioning holes on the upper side wall of the B-pillar and the connecting plate form a triangular prototype, of which two acute angles are ≥30º and ≤60º, and the turning angles of the reference plate 101 and the flap 102 in the reference pin seat 10, as well as the turning angles of the strip block 221 and the plate block 222 in the adapter block 22 are all obtained by converting the acute angles of the triangle, and the conversion results are also the same obtuse angles.

[0035] In summary, the tooling structure is stable, strong enough, and has small deformation; it is reliable to use, easy to install and practical, and has high versatility.

[0036] In addition to the above embodiments, the utility model may also have other implementations. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the utility model.
