Description

Technical Field

[0001] This utility model relates to the field of auxiliary tooling technology for assembling roof components of rail transit vehicles, and in particular to a flexible positioning tooling for switching between multiple vehicle models on the roof. Background Technology

[0002] Existing roof fixtures, such as Figure 1 As shown, the roof curved beam positioning adopts a single independent column positioning method, that is, a set of positioning blocks are fixed at the top of each column, and a set of roof curved beams are installed on each set of positioning blocks. Each urban rail passenger car has dozens of sets of curved beams on its roof, requiring dozens of sets of columns. The number of curved beams and the spacing dimensions vary between different models. When changing models, it is necessary to repeatedly adjust the position of dozens of sets of columns, including adding, removing, and replacing columns, as well as checking the straightness. Due to the large number of roof curved beams, adjusting the roof when changing models is difficult, time-consuming, labor-intensive, and inefficient.

[0003] In addition, when assembling the roof beams, there is only one center positioning block on the tooling. The two ends of the roof beams are manually marked, which takes one hour for one operator. The center hole of the beam is aligned with the positioning line by visual inspection by the operator. There are deviations in the positioning dimensions of the roof beams of the whole vehicle and the straightness of each beam.

[0004] Therefore, based on the above problems, it is necessary to provide a flexible positioning fixture for switching between multiple vehicle models on the roof, which can be quickly adjusted, improve the efficiency of tooling change and the positioning accuracy of the roof beam, and reduce the labor intensity of manual operation. Utility Model Content

[0005] The purpose of this invention is to overcome the defects of the existing technology and provide a flexible positioning tooling for switching between multiple vehicle models on the roof. This tooling solves the problems of difficulty and low efficiency caused by the need to move many support columns when adjusting existing roof tools for different models.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model discloses a flexible positioning fixture for switching between multiple vehicle models on a car roof, comprising:

[0008] Multiple support units and at least one crossbeam;

[0009] The support unit includes a side column with a clamp installed at the top and a column positioned between the two side columns. The top of the column is fixedly connected to the bottom of the crossbeam, and the crossbeam is arranged perpendicular to the length direction of the roof beam.

[0010] The top of the crossbeam can be fixedly connected to a positioning component at any position via a sliding groove. In the working state, the crossbeam can support the roof curved beam at any position along the length of the roof via the positioning component.

[0011] Furthermore, auxiliary support seats extending toward the side column are fixedly connected to both sides of the column, and the crossbeam is fixedly connected to the top of the auxiliary support seats.

[0012] Furthermore, the column includes a body, and side plates are fixedly connected to both sides of the body for connection with the auxiliary support base.

[0013] Furthermore, the auxiliary support base has an installation point at its end for installing the crossbeam, and the installation points of the auxiliary support base on both sides of the column are symmetrically arranged.

[0014] Furthermore, the auxiliary support base includes an auxiliary arm plate, one end of which is fixedly connected to a vertically arranged upright plate, and the other end is fixedly connected to a horizontally arranged cross plate, which is fixedly connected to the cross beam.

[0015] Furthermore, the upper surface of the crossbeam is marked with marking lines to mark the position of the roof beam.

[0016] Furthermore, the positioning component includes a connecting seat and a positioning block fixedly connected to the top of the connecting seat for supporting the roof beam, and the bottom end of the connecting seat is fixedly connected to the crossbeam.

[0017] Furthermore, the positioning component also includes a positioning pin, which is detachably fixed in the groove of the positioning block.

[0018] Furthermore, a side beam positioning block that conforms to the shape of the roof side beam is fixedly connected to the top of the side column, and the clamp is fixedly connected to the side of the side beam positioning block.

[0019] Furthermore, the crossbeam is made of aluminum profile.

[0020] In the above technical solution, the flexible positioning fixture for switching between multiple vehicle models on the roof provided by this utility model has the following advantages:

[0021] This utility model designs a flexible positioning fixture for switching multiple vehicle models on the roof. It utilizes a column to support a continuous crossbeam, and arranges several roof curved beam positioning components on the upper surface of the continuous crossbeam. The positioning components can slide and lock on the upper surface of the crossbeam, and the size and position marks of the roof curved beams of different vehicle models are engraved on the surface of the crossbeam. By sliding the positioning components according to the marks and locking them, rapid adjustment can be achieved. Compared with the existing single column positioning method, this flexible positioning fixture for switching multiple vehicle models on the roof has a fast adjustment speed, high precision, and low labor intensity of manual operation, effectively improving the efficiency of changing vehicle models.

[0022] In addition, each set of roof beams uses three crossbeams, which are quickly positioned by three positioning components. Positioning pins are installed in the positioning block slots of the positioning components. When the positioning blocks are installed on the roof beams, the positioning pins can cooperate with the center holes of the beams, which helps to improve the positioning accuracy of the roof beams and effectively reduces the dimensional deviation of the assembly by manual marking and visual alignment by the operator.

[0044] See Figure 2 As shown;

[0045] A utility model discloses a flexible positioning fixture for switching between multiple vehicle models on a car roof, comprising:

[0046] Multiple support units and at least one crossbeam 3, wherein the support unit includes a side column 1 with a clamp 102 mounted on its top and a column 2 disposed between two side columns 1;

[0047] The top of the column 2 is fixedly connected to the bottom of the crossbeam 3, and the crossbeam 3 is set perpendicular to the length direction of the roof curved beam 6, with multiple support units supporting the crossbeam 3 simultaneously;

[0048] The top of the crossbeam 3 can be fixedly connected to a positioning component at any position via the slide groove 301. In the working state, the crossbeam 3 can support the roof curved beam 6 at any position along the length of the roof via the positioning component.

[0049] Specifically, the flexible positioning fixture includes multiple support units, which are spaced apart along the length of the vehicle roof according to actual needs, and the number can be increased or decreased.

[0050] The support unit includes side column 1 and column 2;

[0051] The top of the side post 1 is fixed with a side beam positioning block 101 for mounting the roof side beam. During assembly, the two ends of the roof curved beam 6 are attached to the roof side beam. The side beam positioning block 101 is equipped with a clamp 102. This clamp is existing technology. The top of the clamp body of the clamp 102 is screwed with a lead screw 1021. The lead screw 1021 provides clamping force, thereby pressing the roof side beam or the roof curved beam 6 from above.

[0052] A crossbeam 3 is fixedly connected to the top of the column 2, and the crossbeam 3 is set along the length of the roof. The top of the crossbeam 3 is positioned and supported at any position on the roof curved beam 6 through positioning components. This allows the flexible positioning fixture for switching multiple vehicle models to meet the needs of different vehicle models. It is easy to adjust, and the adjustment efficiency and accuracy are high. This flexible positioning fixture for switching multiple vehicle models changes the single column positioning method in the existing technology, thereby solving the problems of difficult adjustment when changing vehicle models, time-consuming and labor-intensive operation, high operator labor intensity, low adjustment efficiency and low positioning accuracy of the curved beam.

[0053] See Figure 2 As shown:

[0054] Preferably, auxiliary support seats 5 extending toward the side column 1 are fixedly connected to both sides of the column 2. The support width of the column 2 is extended in the width direction of the roof through the auxiliary support seats 5. A crossbeam 3 is fixedly connected to the top of the auxiliary support seat 5. That is to say, in each support unit, the column 2 uses three crossbeams 3 to support the roof curved beam 6.

[0055] See Figure 3 , 4 As shown:

[0056] Preferably, the column 2 includes a main body, with side plates 201 fixedly connected to both sides of the main body for connection to the auxiliary support base 5. In this structure, the bottom end of the column 2 main body is detachably and fixedly connected to the ground infrastructure through a base plate, and the top end is detachably and fixedly connected to the crossbeam 3 through a top plate by bolts. The side plates 201 are welded to the sides of the column 2 main body, and the side plates 201 are detachably and fixedly connected to the auxiliary support base 5 by bolts.

[0057] See Figure 2 As shown:

[0058] Preferably, the auxiliary support base 5 has an installation point for mounting the crossbeam 3 at its end, and the installation points of the auxiliary support base 5 on both sides of the column 2 are symmetrically arranged, so that the column 2 can simultaneously support three crossbeams 3, thereby positioning the roof curved beam 6 at multiple points. The installation point at the end of the auxiliary support base 5 is conducive to being close to the end of the roof curved beam 6, increasing the distance between the crossbeam 3 at the center position of the column 2 and the crossbeams 3 at both ends, making the support of the roof curved beam 6 more stable and reliable. Of course, according to actual needs, installation points can also be added to the auxiliary support base 5, and the roof curved beam 6 can be supported by three or more crossbeams 3.

[0059] See Figure 8 , 9 As shown in Figure 10:

[0060] The auxiliary support base 5 includes an auxiliary arm plate 501. One end of the auxiliary arm plate 501 is fixedly connected to a vertically arranged upright plate 502, and the other end is fixedly connected to a horizontally arranged cross plate 503. The cross plate 503 is fixedly connected to the cross beam 3. During assembly, one end of the auxiliary arm plate 501 is detachably and fixably connected to the side plate 201 on the column 2 via the upright plate 502 using bolts, and the other end is detachably and fixably connected to the cross beam 3 via the horizontally arranged cross plate 503 using bolts.

[0061] Preferably, the upper surface of the crossbeam 3 is marked with marking lines to mark the position of the roof curved beam 6, which makes adjustment convenient.

[0062] See Figure 2 , 5 As shown in Figure 6:

[0063] Preferably, the positioning component includes a connecting seat 4 and a positioning block 401 fixedly connected to the top of the connecting seat 4 for supporting the roof curved beam 6. The bottom end of the connecting seat 4 is fixedly connected to the crossbeam 3. Specifically, the connecting seat 4 is constructed as an I-shaped structure. Its bottom end can be fixedly connected to any position of the T-shaped groove 301 opened on the upper surface of the crossbeam 3 by bolts. The top end is fixedly connected to the positioning block 401 by bolts, and the positioning block 401 supports the roof curved beam 6.

[0064] See Figure 6 , 7 As shown:

[0065] The positioning component also includes a positioning pin 403. The positioning pin 403 is detachably fixed in the groove 402 of the positioning block 401 for engaging with the center hole of the roof beam 6. By fixing the positioning pin 403 in the groove 402 of the positioning block 401 and inserting the positioning pin 403 into the center hole on the roof beam 6, the positioning block 401 can position and support the roof beam 6, thereby avoiding the step of manually marking and positioning the roof beam 6 and effectively improving work efficiency.

[0066] See Figure 2a As shown:

[0067] Preferably, the top of the side pillar 1 is fixedly connected to the side beam positioning block 101 that conforms to the shape of the roof side beam, and the side beam positioning block 101 is fixedly connected to the side of the clamp 102. The clamp 102 presses the curved beam from the top of the roof curved beam 6. In this embodiment, in order to ensure that the roof side beam and the side beam positioning block 101 fit tightly and are fixed, multiple independent side beam clamps 103 can be added between the roof side beam and the side beam positioning block 101 to assist in clamping the roof side beam. This is beneficial to control and ensure the key dimension of the center position height of the roof curved beam 6. The clamp 102 is installed on the side of the side beam positioning block 101, and the screw 1021 of the clamp 102 contacts the roof side plate. After the clamp 102 presses the roof side plate and the roof curved beam 6 tightly, spot welding is performed.

[0068] See Figure 11 As shown:

[0069] Preferably, the crossbeam 3 is made of aluminum profile with a quadrilateral cross-section. T-shaped grooves 301 are provided on all four surfaces of the aluminum profile. The T-shaped grooves 301 extend along the length of the crossbeam 3, thereby cooperating with the bolts on the connecting seat 4. The position of the connecting seat 4 can be adjusted and fixed at any position along the length of the crossbeam 3.

[0070] In the above technical solution, this utility model provides a flexible positioning tool for switching multiple vehicle models on the roof, and a method of using it;

[0071] First, the bottom of the column 2 is installed on the ground, and the top of the column 2 supports three long crossbeams 3. The size and position marks of the roof curved beams of different models are engraved on the upper surface of the crossbeams 3. At the same time, the roof curved beams 6 are positioned by several positioning parts on the crossbeams 3. Each roof curved beam corresponds to three positioning parts, which has good positioning reliability and high accuracy.

[0072] Secondly, the connecting seat 4 of the positioning component is installed on the crossbeam 3 by bolts, the positioning block 401 is placed on the top of the connecting seat 4 and locked by bolts, the roof curved beam is placed in the groove 402 of the positioning block 401, the positioning pin in the groove 402 is inserted into the center hole of the roof curved beam, and is positioned by the positioning surface of the positioning block 401 on the three crossbeams.

[0073] When changing vehicle models, loosen the fastening bolts on the connecting seat 4 and the crossbeam 3, slide and adjust the position of the positioning block 401, and after confirming that it is the required position, tighten the bolts on the connecting seat 4 and the crossbeam 3 to fix it. In this way, each time the vehicle model is changed, the position of the connecting seat 4 on the crossbeam 3 is slid according to the size and position mark to achieve the purpose of quick adjustment.
