Abstract
Description
Technical Field
[0001] This application relates to the field of automotive manufacturing tooling technology, and in particular to a conveyor line positioning bracket, a rear floor side beam, and a method of using them. Background Technology
[0002] As automotive production lines become increasingly flexible, a single production line can accommodate the production of different car models. However, this requires that the positioning holes on the bottom of the body-in-white align with the positioning pins on the conveyor line. Currently, flexible production lines typically have only two to three sets of positioning pins due to space limitations in the positioning pin mechanism. All car models that need to be introduced into this production line must select one of these two to three sets of positioning pins to design positioning holes. Generally, positioning holes are designed on the rear floor longitudinal beams. However, with the continuous increase in car models, the existing positioning pins on flexible production lines are increasingly unable to meet the needs of car model introduction. Many car models cannot have their positioning holes designed directly on the longitudinal beams due to structural and dimensional reasons. To achieve flexible production, it is often necessary to add large positioning brackets to the side beams and then design the positioning holes on the positioning brackets, which increases the cost and weight of the entire vehicle and also leads to waste.
[0003] The current problems with flexible production lines present a challenge in achieving both the adoption of flexible production lines for vehicle models and avoiding any weight or cost burden on the entire vehicle. Summary of the Invention
[0004] This application provides a conveyor line positioning bracket, a rear floor side beam, and a method of use, which achieves both the requirement of flexible line introduction for vehicle models and the avoidance of adding weight and cost burden to the entire vehicle.

[0018] The positioning bracket reinforcing plate has a reinforcing plate positioning through hole at the position corresponding to the positioning through hole of the conveyor line.
[0019] In some embodiments, the diameter of the positioning through hole of the conveyor line is larger than the diameter of the positioning through hole of the reinforcing plate.

[0021] In some embodiments, the difference between the diameter of the positioning through hole of the conveyor line and the diameter of the positioning through hole of the reinforcing plate is 1 mm.
[0022] In some embodiments, the surface where the positioning via of the conveyor line is located is a plane;
[0023] And / or, the surface where the positioning through hole of the reinforcing plate is located is a plane.

Detailed Implementation
[0044] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0045] See Figure 1 and Figure 2 As shown in the figure, this application embodiment provides a conveyor positioning bracket, which includes a first positioning mounting side 1, a positioning mounting top surface 2, and a second positioning mounting side 3; the positioning mounting top surface 2 is connected to the top of the first positioning mounting side 1, and a conveyor positioning through hole 20 is provided on the positioning mounting top surface 2; the second positioning mounting side 3 is connected to both sides of the first positioning mounting side 1, the top of each of the second positioning mounting side 3 is connected to the positioning mounting top surface 2, and the second positioning mounting side 3 and the positioning mounting top surface 2 are both located on the same side of the first positioning mounting side 1; a positioning bracket mounting hole 30 is provided on the second positioning mounting side 3.
[0046] In this application, a conveyor line positioning through hole 20 is provided on the top surface 2 of the positioning installation, which can realize the assembly purpose with the conveyor line positioning pin, thereby solving the problem of incompatibility due to structural and layout limitations when different models are produced on the same welding and painting line. A first positioning installation side 1 and a second positioning installation side 3 are provided below the top surface 2 of the positioning installation to support the top surface 2 of the positioning installation. At the same time, a positioning bracket mounting hole 30 is provided on the second positioning installation side 3, which is compatible with the side beam mounting hole 50 on the rear floor side beam. The conveyor line positioning bracket can be installed and fixed on the rear floor side beam with fasteners. Since the conveyor line positioning bracket is installed on the rear floor side beam with fasteners such as bolts, after passing through the welding workshop, painting workshop and all the way to the final assembly workshop, the conveyor line positioning bracket and fasteners can be disassembled, so it will not affect the installation of the frame, and at the same time, it also reduces the weight of the whole vehicle. In addition, the conveyor line positioning bracket and fasteners can be reused after disassembly, reducing the manufacturing cost of the whole vehicle.
[0047] Therefore, the conveyor positioning bracket provided in this application satisfies the requirement of flexible line introduction for vehicle models without imposing a weight or cost burden on the entire vehicle.
[0048] The side of the positioning bracket for the conveyor line in this application is composed of a first positioning mounting side 1 and two second positioning mounting side 3. Compared with the traditional positioning bracket side which is composed of four sides, this application can reduce the weight of the parts, reduce the difficulty of manufacturing the parts, and facilitate precision control.
[0049] See Figure 1 As shown, for ease of installation, the end of the second positioning mounting side 3 away from the positioning mounting top surface 2 is bent to form a first bending surface 31, and the positioning bracket mounting hole 30 is provided on the first bending surface 31.
[0050] Combination Figure 3 As shown, the end of the second positioning mounting side 3 away from the positioning mounting top surface 2 is bent into a first bending surface 31. During assembly, the first bending surface 31 can be attached to the rear floor side beam. After installation using fasteners 6 in conjunction with the positioning bracket mounting holes 30, the stability and connection strength of the conveyor line positioning bracket during use are ensured.
[0051] Further, see Figure 1 and Figure 2 As shown, the end of the second positioning mounting side 3 away from the first positioning mounting side 1 is bent to form a second bent surface 32, and the second bent surface 32 is provided with the positioning bracket mounting hole 30.
[0052] Combination Figure 3As shown, the end of the second positioning mounting side 3 away from the first positioning mounting side 1 is bent into a second bending surface 32. During assembly, the second bending surface 32 can be attached to the rear floor side beam. After installation using fasteners 6 in conjunction with the positioning bracket mounting holes 30, the stability and connection strength of the conveyor line positioning bracket during use are ensured.
[0053] Meanwhile, by designing mounting holes 30 for the positioning bracket on different bending surfaces and assembling them with fasteners 6, the stability, connection strength, and positional accuracy of the positioning holes 20 of the conveyor line are further increased.
[0054] Further, see Figure 1 and Figure 2 As shown, the portion of the first bent surface 31 away from the first positioning and mounting side 1 is connected to the portion of the second bent surface 32 away from the positioning and mounting top surface 2 via the first arc connecting portion 33.
[0055] The first arc connecting part 33 connects the different bending surfaces into a whole, so that the first bending surface 31, the second bending surface 32 and the second positioning and mounting side surface 3 form a three-dimensional support structure, which further improves the stability, connection strength and positional accuracy of the conveyor line positioning bracket after fixing.
[0056] The number of positioning bracket mounting holes 30 on the first bending surface 31 and the second bending surface 32 can be determined according to actual installation needs. For example, as an example, one positioning bracket mounting hole 30 is designed on the first bending surface 31 and two positioning bracket mounting holes 30 are designed on the second bending surface 32, so that there are three positioning bracket mounting holes 30 on the second positioning mounting side 3. Since the conveyor positioning bracket has two second positioning mounting side 3s, six positioning bracket mounting holes 30 are designed on the conveyor positioning bracket.
[0057] See Figure 1 As shown, the first positioning mounting side 1, the positioning mounting top surface 2, and the second positioning mounting side 3 together enclose the inner cavity 10 of the positioning bracket. The first bending surface 31 and the second bending surface 32 also have different directions when bending, for example, see Figure 1 As shown, the first bending surface 31 and the second bending surface 32 can be bent outward so that the first bending surface 31 and the second bending surface 32 are located outside the inner cavity 10 of the positioning bracket; or, for example, the first bending surface 31 and the second bending surface 32 can be bent inward so that the first bending surface 31 and the second bending surface 32 are located inside the inner cavity 10 of the positioning bracket.
[0058] Understandably, in order to improve the installation stability of the conveyor positioning bracket and reduce the installation difficulty of the fastener 6, the first bending surface 31 and the second bending surface 32 are bent outward so that the first bending surface 31 and the second bending surface 32 are located outside the inner cavity 10 of the positioning bracket.
[0059] To improve manufacturing efficiency and overall structural strength, the conveyor positioning bracket provided in this application can be manufactured using a stamping process. Specifically, the conveyor positioning bracket provided in this application is a stamped sheet metal part. See details... Figure 1 As shown, the top surface 2 of the positioning and mounting is formed by bending the top of the first positioning and mounting side surface 1, and the second positioning and mounting side surface 3 is formed by bending the side of the first positioning and mounting side surface 1.
[0060] Specifically, see Figure 1 As shown, the top of the first positioning mounting side 1 is bent downwards until it is approximately perpendicular to the first positioning mounting side 1 to form the positioning mounting top surface 2, and the side of the first positioning mounting side 1 is bent in a direction that approaches each other until it is approximately perpendicular to the first positioning mounting side 1 to form the second positioning mounting side 3.
[0061] It is understood that the area connecting the first positioning mounting side 1 and the positioning mounting top surface 2, as well as the area connecting the first positioning mounting side 1 and the second positioning mounting side 3, forms a second arc-shaped connecting portion.
[0062] To improve the support strength of the second positioning mounting side 3 to the positioning mounting top surface 2, see [reference needed]. Figure 1 and Figure 2 As shown, the top surface 2 of the positioning installation is bent towards the second positioning installation side surface 3 on both sides to form a self-welding surface 21 of the positioning bracket, and the self-welding surface 21 of the positioning bracket is welded to the second positioning installation side surface 3.
[0063] In this application, the self-welding surface 21 of the positioning bracket is a short surface that bends from top to bottom. Compared with the long surface formed by bending left and right in the traditional structure, the material utilization rate of the parts in this application is higher and the bending difficulty is greatly reduced while ensuring the connection and support strength.
[0064] Furthermore, the self-welding surface 21 of the positioning bracket in this application is bent from top to bottom, which makes the force transmission smoother and can improve the support strength of the second positioning mounting side 3 to the positioning mounting top surface 2. Specifically, when the traditional left and right bending method is used, the force on the positioning mounting top surface 2 needs to detour to the left and right sides before it can be transmitted to the second positioning mounting side 3. However, in this application, the force on the positioning mounting top surface 2 can be directly transmitted downward to the second positioning mounting side 3, thereby directly supporting the positioning mounting top surface 2.
[0065] See Figure 1 and Figure 2 As shown, the first positioning mounting side 1, the positioning mounting top surface 2, and the second positioning mounting side 3 together enclose to form the positioning bracket inner cavity 10; the conveyor positioning bracket also includes a U-shaped positioning bracket reinforcing plate 4, which is located in the positioning bracket inner cavity 10 and is connected to both the positioning mounting top surface 2 and the second positioning mounting side 3; a reinforcing plate positioning through hole 40 is provided on the positioning bracket reinforcing plate 4 at the position corresponding to the conveyor positioning through hole 20.
[0066] The positioning bracket reinforcing plate 4 has a U-shaped structure, which overlaps on three sides by welding with the top positioning mounting surface 2 and the second positioning mounting side surface 3. The structure is stable and provides the necessary strength and rigidity to support the positioning pins of the conveyor line. If the strength of the conveyor line positioning bracket is insufficient, it can be reinforced by the positioning bracket reinforcing plate 4, thereby avoiding the need to increase the weight of the entire conveyor line positioning bracket and reducing its overall weight.
[0067] Since the positioning bracket reinforcing plate 4 needs to be welded to the top surface 2 and the second side surface 3 of the positioning mounting, if the welding causes misalignment between the conveyor line positioning through hole 20 and the reinforcing plate positioning through hole 40, resulting in a "double eyelid," it may make it difficult to install the conveyor line positioning pin. Therefore, to absorb the precision error generated during the welding process, the diameter of the conveyor line positioning through hole 20 is larger than the diameter of the reinforcing plate positioning through hole 40. This differential hole diameter design can absorb the precision error generated during the welding process, ensuring that the conveyor line positioning pin can be accurately placed into the hole provided by the conveyor line positioning bracket.
[0068] The difference in diameter between the conveyor line positioning through hole 20 and the reinforcing plate positioning through hole 40 can be designed according to actual needs. For example, the difference between the diameter of the conveyor line positioning through hole 20 and the diameter of the reinforcing plate positioning through hole 40 is 1 to 2 mm.
[0069] As a preferred example, the difference between the diameter of the conveyor line positioning through hole 20 and the diameter of the reinforcing plate positioning through hole 40 is 1 mm.
[0070] Furthermore, the surface where the positioning through hole 20 of the conveyor line is located is a plane, and the surface where the positioning through hole 40 of the reinforcing plate is located is a plane.
[0071] This application uses a flat surface instead of a perforated surface. This design allows the painting positioning pin locking mechanism to pass through the conveyor positioning through hole 20 and lock onto the surface where the conveyor positioning through hole 20 is located. During the process of the body-in-white entering the electrophoresis tank and flipping in the electrophoresis tank, it can ensure that the body-in-white is firmly locked onto the conveyor trolley and prevent it from falling into the electrophoresis tank. In contrast, the traditional car structure has a perforated surface, which cannot lock the body-in-white through the painting positioning pin locking mechanism and cannot allow the body-in-white to be fully flipped for electrophoresis.
[0072] During the conveying process, the body-in-white rotates inside the electrophoresis tank after entering, causing downward pressure on the positioning brackets of the conveyor line. To alleviate the pressure on the painting positioning pin locking mechanism, see [reference needed]. Figure 2 As shown, there is a gap between the second positioning mounting side 3 and the positioning mounting top surface 2, so that the second positioning mounting side 3, the positioning mounting top surface 2, the positioning bracket self-welding surface 21 and the positioning bracket reinforcing plate 4 enclose and form a buffer cavity 41. By designing the buffer cavity 41, the buffer cavity 41 is used to absorb the downward pressure of the white body, thereby protecting the painting positioning pin locking mechanism.
[0073] Further, see Figure 2 and Figure 3 As shown, among the second positioning mounting sides 3 connected to the two sides of the first positioning mounting side 1, one of the second positioning mounting sides 3 is perpendicular to the positioning mounting top surface 2, and the other second positioning mounting side 3 is clamped to the positioning mounting top surface 2 at an obtuse angle γ.
[0074] The conveyor line positioning bracket is designed with a right-angled trapezoidal structure on the side. It is supported by the vertically set second positioning mounting side 3. While supporting the second positioning mounting side 3 at an angle, it can also transmit and unload ballast due to its angled arrangement. When the conveyor line positioning bracket supports the entire body-in-white, it can take into account both support and force transmission and unloading, preventing the conveyor line positioning bracket from being crushed, thereby improving the service life of the conveyor line positioning bracket.
[0075] Understandably, the range of values for the obtuse angle γ can be determined based on actual needs. For example, as an example, the range of values for the obtuse angle γ is (90°, 105°). As a preferred example, the value of the obtuse angle γ is 100°.
[0076] See Figure 1 As shown, in the area where the second positioning mounting side 3 is connected to the first positioning mounting side 1, a weight-reducing notch 35 is formed in the part away from the positioning mounting top surface 2, which can reduce the weight of the bracket.
[0077] See Figure 1As shown, the second positioning mounting side 3 is provided with positioning bracket positioning holes 34. There are two positioning bracket positioning holes 34 arranged vertically. The positioning bracket positioning holes 34 are used to accurately position the parts. Traditional automotive structures do not have positioning holes, which makes accurate positioning impossible and is not conducive to the accuracy control of the positioning through hole 20 of the conveyor line.
[0078] See Figure 4 and Figure 5 As shown, in order to adapt to the above-mentioned conveyor line positioning bracket, this application embodiment also provides a rear floor side beam, the rear floor side beam including a side beam body 5, the side beam body 5 being provided with a side beam mounting hole 50 for installing the conveyor line positioning bracket, the side beam mounting hole 50 being adapted to the positioning bracket mounting hole 30 on the conveyor line positioning bracket.
[0079] The side beam body 5 includes a front section 51 of the rear floor side beam, a rear section 52 of the rear floor side beam, and a rear crossbeam connecting plate 53. The front section 51 of the rear floor side beam is welded to the rear section 52 of the rear floor side beam, and the rear crossbeam connecting plate 53 is welded at the welding position of the front section 51 of the rear floor side beam and the rear section 52 of the rear floor side beam, providing lateral support for the rear floor side beam.
[0080] This application embodiment also provides a method for using the conveyor line positioning bracket, which includes the following steps:
[0081] 101: Place the conveyor line positioning bracket on the rear floor side beam so that the positioning bracket mounting hole 30 is aligned with the side beam mounting hole 50 on the rear floor side beam.
[0082] 102: Fasten the fastener 6 to the positioning bracket mounting hole 30 and the side beam mounting hole 50 to fix the conveyor positioning bracket and the rear floor side beam; the fastener 6 can be common parts such as bolts.
[0083] 103: After the conveyor line positioning pin is connected to the conveyor line positioning through hole 20, it is conveyed through the welding workshop and painting workshop to the final assembly workshop, thus carrying out the conveying work.
[0084] 104: After the conveying work is completed, remove the conveyor line positioning bracket from the rear floor side beam.
[0085] In the final assembly workshop, the aforementioned conveyor line positioning bracket is not required; it can be removed by unfastening fastener 6.
[0086] The disassembled conveyor positioning brackets and fasteners 6 are packed in containers and transported from the final assembly workshop to the welding workshop. The conveyor positioning brackets can then be assembled on other vehicles in the welding workshop.
[0087] By completing all the above steps, a cycle is finished, thus achieving the effect of cyclical use.
[0088] By reusing the bracket, the weight of a single bicycle can be reduced by at least 1.2 kg, and the cost can be reduced by at least 18 yuan, thus reducing the waste of resources in the whole bicycle.
