Description

Technical Field

[0001] The present application relates to the technical field of motor vehicle manufacturing, and in particular to a roof frame module assembly welding tool. Background Art

[0002] The roof frame of a train not only supports and protects the train, but also supports the entire train body. As a relatively complex structure, the design, manufacturing and material selection of the roof frame are all designed to meet the requirements of strength, lightness and functionality. During the production process, the quality and performance of the roof frame are ensured through sophisticated process flow and high-quality material selection.

[0003] In the existing manufacturing process, a three-dimensional stretch-bending process is commonly used. In this manufacturing process, the structure is complex and changeable, and the size of the parts is difficult to measure.

[0004] In addition, the roof frame can be processed by a profiling frame so that the roof frame can be separated from the profiling frame after processing. However, how to prevent the displacement of the reference plane of the roof frame during the manufacturing process and ensure that the roof frame can be smoothly ejected after welding is a key issue that needs to be considered. Utility Model Content

[0005] The purpose of the present application is to provide a roof frame module assembly welding tool, which can ensure the reliable positioning of its reference surface during the manufacturing process of the roof frame and facilitate the overall tire production after processing.

[0006] In order to achieve the above-mentioned object, the utility model provides a roof frame module assembly welding tool, comprising a contour frame following the shape of the roof frame, and positioning plates are arranged on both sides of the top of the contour frame, and the positioning plates extend along the length direction of the contour frame;

[0007] A positioning block for positioning a reference surface of the roof frame is movably mounted on the positioning plate, and the positioning block can translate in the width direction of the contour frame.

[0008] In an optional embodiment, a slide rail is provided on the top of the positioning plate, the slide rail extends along the width direction of the contoured frame, and a slide groove that cooperates with the slide rail is provided on the positioning pressing block.

[0009] In an optional embodiment, the positioning block is fixed by a positioning card, the side of the positioning plate is connected to a clamp column, the clamp column is connected to a clamp arm, the end of the clamp arm is connected to a threaded sleeve, and the positioning card includes a screw threaded in the threaded sleeve and a pressure seat connected to the bottom of the screw.

[0010] In an optional embodiment, the contoured frame includes a frame base, and a support plate with an arc-bent edge connected to the frame base, and the support plates are evenly distributed in the length direction of the contoured frame.

[0011] In an optional embodiment, a copper plate extending along the length direction of the contour frame is connected between the support plates, and the length of the copper plate is the same as the length direction of the contour frame.

[0012] In an optional embodiment, the connection position of the copper plate is opposite to the longitudinal beam position of the roof frame, and is used to position and support the longitudinal beam;

[0013] A positioning line for positioning the longitudinal beam is arranged on the copper plate, and a positioning pin for positioning the longitudinal beam is arranged on the side of the positioning line.

[0014] In an optional embodiment, a ground plate is provided at the bottom of the frame base, the ground plate is distributed at the corners of the frame base, and leveling bolts are provided on the ground plate.

[0015] In an optional embodiment, the bottom of the support plate is connected to the frame base, and the top of the support plate is connected to the positioning plate.

[0016] In an optional embodiment, it further includes end panels with arc edges, the end panels are arranged at both ends of the contoured frame in the length direction, and the arc edges of the end panels follow the arc-bent edges of the support plate.

[0017] By providing a contour frame that follows the shape of the roof frame, the roof frame can be processed and manufactured using the contour frame.

[0018] The positioning plates arranged on both sides of the top of the profiling frame and extending along the length direction of the profiling frame can determine the reference surface of the roof frame. Combined with the positioning pressure blocks movably installed on the positioning plates, they can be used to locate the reference surface of the roof frame to keep the reference surface of the roof frame stable and reliable.

[0019] During the manufacturing process, the movable positioning block can be used to detect and locate the installation position and size of the roof frame curved beam. The reference plane of the roof frame can be determined by fitting the two ends of the cut curved beam to the bottom wall of the positioning block respectively.

[0020] The positioning block can translate in the width direction of the profiling frame. When the positioning block moves outward in the width direction of the profiling frame, that is, when the positioning block is flush with or retreats relative to the positioning plate, it can facilitate the determination of the size and position of the bent beam in the welding space.

[0021] After the cutting size of the bent beam is determined and the bent beam is installed at the welding position of the profiling frame, the positioning block is moved inward in the width direction of the profiling frame so that the positioning block is pressed against the two top side ends of the bent beam, thereby effectively fixing the bent beam after the reference surface is confirmed, which is beneficial to the reliability of the reference surface of the roof frame during the processing and minimizes the positioning failure of the reference surface.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0035] The roof frame module welding tooling in the present application mainly prevents the displacement and failure of the roof frame reference surface during the processing and manufacturing process by setting a structure for covering and pressing the reference surface of the roof frame.

[0036] See also Figure 1 , and combined with Figure 2-Figure 3 The roof frame module assembly welding tool in the utility model comprises a profiling frame 1 that follows the shape of the roof frame, and positioning plates 11 are arranged on both sides of the top of the profiling frame 1, and the positioning plates 11 extend along the length direction of the profiling frame 1;

[0037] A positioning block 2 for positioning a reference surface of the roof frame is movably mounted on the positioning plate 11 . The positioning block 2 can translate in the width direction of the contour frame 1 .

[0038] The contoured frame 1 has a certain space for welding operation. The roof frame is mainly composed of a bent beam and a longitudinal beam welded together. The bent beam serves as a cross beam of the roof frame, which is conducive to forming a dome structure of the roof frame.

[0039] By arranging positioning plates 11 on both sides of the top of the profiling frame 1, the bent beam can be effectively placed in the welding operation space so that the bending curvature of the bent beam follows the contour shape of the welding operation space. On the premise of determining the correct installation position of the bent beam, the size of the bent beam can be determined through the positioning plates 11, which is conducive to the cutting and determination of the size of the ends of the two sides of the bent beam.

[0040] The positioning plate 11 extends along the length direction of the profiling frame 1 , and can determine the placement position and size of each curved beam in the overall length direction of the profiling frame 1 .

[0041] The roof frame includes multiple curved beams, which are arranged at intervals in the length direction of the contoured frame 1. The reference plane of the roof frame is determined by the top surfaces of the side ends of the multiple curved beams. By movably installing the positioning block 2 on the positioning plate 11, the curved beams with determined placement positions and sizes can be pressed and fixed, thereby effectively positioning and fixing the reference plane of the roof frame.

[0042] In order to facilitate the placement of the bent beam in the welding operation space and to fix and press the positioned bent beam, the positioning block 2 can translate in the width direction of the contoured frame 1, that is, after the positioning block 2 extends relative to the positioning plate 11 and extends into the welding operation space, the side end of the bent beam is pressed and fixed.

[0043] After the positioning block 2 retreats relative to the positioning plate 11 and avoids the welding operation space, it is convenient to adjust the placement position of the bent beam and determine the cutting size.

[0044] A slide rail 12 is provided on the top of the positioning plate 11, and the slide rail 12 extends along the width direction of the contoured frame 1. A slide groove (not shown in the figure) that cooperates with the slide rail 12 is provided on the positioning block 2. The positioning block 2 can be translated as a whole on the top of the positioning plate 11 through the cooperation between the slide rail 12 and the slide groove.

[0045] In order to ensure the effectiveness and reliability of the press fitting, the positioning block 2 is fixed by a positioning clamp 3, and the side of the positioning plate 11 is connected to a clamp column 21, and the clamp column 21 is connected to a clamp arm 22 extending into the welding operation space, and the end of the clamp arm 22 is connected to a threaded sleeve 23.

[0046] The positioning card 3 includes a screw rod 31 threaded in the threaded sleeve 23 and a pressing seat 32 connected to the bottom of the screw rod 31. Specifically, the pressing seat 32 at the bottom of the positioning card 3 is used to press the top wall of the positioning block 2 to achieve fixed locking.

[0047] At the same time, the screw 31 and the threaded sleeve 23 cooperate with each other to play the role of lifting the screw, and the screw 31 can be lifted and lowered, which is conducive to adjusting the contact and separation between the pressure seat 32 and the positioning pressure block 2.

[0048] The contour frame 1 comprises a frame base 13 and a support plate 14 with an arc-bent edge connected to the frame base 13. The support plates 14 are evenly distributed in the length direction of the contour frame 1, so that the welding operation space can follow the shape of the roof frame.

[0049] After the roof frame is welded, that is, after the curved beam and the longitudinal beam are assembled and welded in the welding operation space, they need to be separated as a whole to realize the removal of the welded roof frame from the contoured frame 1 .

[0050] Furthermore, in order to achieve the positioning of the longitudinal beam and facilitate the overall tire production, a copper plate 15 extending along the length direction of the profiling frame 1 is connected between the support plates 14. The copper plate 15 is specifically a full-length structure, and the length of the copper plate 15 is the same as the length direction of the profiling frame 1.

[0051] From the perspective of positioning the longitudinal beam, the connection position of the copper plate 15 is opposite to the longitudinal beam of the roof frame, and is used to position and support the longitudinal beam.

[0052] Furthermore, a positioning line 16 for positioning the longitudinal beam is provided on the copper plate 15 , and a positioning pin 17 for positioning the longitudinal beam is provided on the side of the positioning line 16 .

[0053] The longitudinal beam of the roof frame is specifically an L-shaped angle steel structure. The angle steel can be seated on the positioning pin 17 with its back facing the positioning pin 17 to achieve overlapping of the longitudinal beam on the copper plate 15 .

[0054] The arrangement of the copper plate 15 can prevent welding adhesion, thereby ensuring the smooth production of the overall structure after welding to the greatest extent. The positioning pin 17 is specifically a Φ10*50 cylindrical positioning pin 17, which can position the longitudinal beam between the curved beams.

[0055] Anchor plates 18 are provided at the bottom of the frame base 13 . The anchor plates 18 are distributed at the corners of the frame base 13 , and leveling bolts 19 are provided on the anchor plates 18 .

[0056] Specifically, a pad 4 is provided below the anchor plate 18, a leveling bolt 19 is threadedly connected to the anchor plate 18, and the bottom end of the leveling bolt 19 abuts against the pad 4, the pad 4 is placed on the ground, and the horizontality of the contour frame 1 can be adjusted by rotating and raising and lowering the leveling bolt 19 to prevent the contour frame 1 from shaking due to uneven ground.

[0057] The bottom of the support plate 14 is connected to the frame base 13, the top of the support plate 14 is connected to the positioning plate 11, the copper plate 15 is connected to the arc-bent edge of the support plate 14, and is arranged according to the connection position of the longitudinal beam and the curved beam, so that the position of the copper plate 15 is opposite to the longitudinal beam to ensure accurate welding assembly.

[0058] The roof frame module assembly welding tool in the present invention also includes end panels with arc edges (not shown in the figure), which are arranged at both ends of the contour frame 1 in the length direction, and the arc edges of the end panels follow the arc edges of the support plate 14. Through this arrangement, the end surface of the roof frame can be effectively determined to ensure the accuracy of the roof frame contour.

[0059] The roof frame module assembly welding tooling in the utility model is mainly composed of steel plates and square tubes. The steel plates are added with a reserved amount for cutting and manufacturing with reference to the outer contour of the roof. Six main body supporting steel plates are arranged, and seven groups of cross beams are arranged, and their positions correspond to the longitudinal beams of the roof frame.

[0060] A 12mm thick copper plate is laid on the beam and fastened with bolts. After the connection is completed, the tooling is processed as a whole, and the outer contour is consistent with the roof contour of the train.

[0061] It should be noted that, in the absence of conflict, the features in the embodiments of this application may be combined with each other.

[0062] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
