[0046] Figure 1 This diagram shows the main structure of a positioning fixture for welding armored vehicle chassis according to an embodiment of this application. Figure 2 This invention relates to a main structural diagram of a positioning fixture for welding armored vehicle chassis, as shown in an embodiment of this application. Figure 1 As shown, a positioning fixture for welding an armored vehicle chassis includes: a base 100, two or more positioning components 200, and two or more gas spring support positioning parts 300; the two or more positioning components 200 and the two or more gas spring support positioning parts 300 are all disposed on the top surface of the base 100; the two or more gas spring support positioning parts 300 are arranged in two parallel rows, suitable for fixing the gas spring supports 1000 of the armored vehicle chassis; the two or more positioning components 200 are arranged in two parallel rows and disposed between the two rows of gas spring support positioning parts 300, suitable for fixing the main beam 800 and the deck 900 of the armored vehicle chassis; the top surface of the base 100 is suitable for supporting the front bottom plate 1200, the middle bottom plate 1300 and the rear bottom plate 1400 of the armored vehicle chassis; two support parts 400 are protruding from the opposite two sides of the base 100, suitable for supporting the wheel wells 1100 of the armored vehicle chassis.

[0047] like Figures 13-18The diagram shows a chassis structure for an armored vehicle welded according to this application. The armored vehicle chassis includes: a main beam 800, a deck 900, four wheel wells 1100, eight gas spring supports 1000, a front floor plate 1200, a middle floor plate 1300, and a rear floor plate 1400. The main beam 800 has a rectangular frame structure. The deck 900 has a rectangular shell structure with an open bottom, and is fixedly connected to the main beam 800 by welding. The four wheel wells 1100 are located on opposite sides of the deck 900 and are fixedly connected to the deck 900 by welding. The four wheel wells 1100 are arranged in pairs facing each other, and each wheel well 1100 consists of two adjacent semi-circular shells with the openings of the shells facing downwards. Suitable for making way for tires; each wheel well 1100 has a gas spring support 1000 welded to the bottom of each well shell. The function of the gas spring support 1000 on the vehicle body is to position the wheel track, wheel width, front overhang, rear overhang, vehicle width and other dimensions of the entire vehicle body. It needs to be welded to the wheel well 1100; the front bottom plate 1200 is set at the front end of the deck 900 and is fixedly connected to the front end of the two wheel wells 1100 and the deck 900 by welding. The middle bottom plate 1300 is set between the four wheel wells 1100 in the middle and is fixedly connected to the two side edges of the four wheel wells 1100 and the deck 900 by welding. The rear bottom plate 1400 is set at the rear end of the deck 900 and is fixedly connected to the rear end of the two wheel wells 1100 and the deck 900 by welding.

[0048] It should be noted that this application is applicable to providing support and positioning for various components of an armored vehicle chassis (deck 900, main beam 800, four wheel wells 1100, eight gas spring supports 1000, front floor plate 1200, middle floor plate 1300, and rear floor plate 1400) during the assembly and welding of the armored vehicle chassis. Specifically, the gas spring support positioning part 300 on the top of the base 100 is used to fix the gas spring support 1000; the positioning assembly 200 on the top of the base 100 is used to fix the main beam 800. The support 400 on top of the base 100 and the deck 900 is suitable for supporting the wheel well 1100 of the armored vehicle chassis; the top of the base 100 can also support and place the front base plate 1200, the middle base plate 1300 and the rear base plate 1400, ensuring the stability of the relative positional relationship between the various components during the welding process, thereby improving welding efficiency, welding accuracy and welding quality, reducing the workload of manual positioning and adjustment by workers, reducing labor intensity, and also reducing welding quality problems caused by human factors.

[0049] In one possible implementation, such as Figure 2As shown, the base 100 includes: a plurality of mounting frames 110 arranged in sequence, and the plurality of mounting frames 110 are arranged parallel to each other; two or more connecting beams 120 are provided between each two adjacent mounting frames 110 to connect the two adjacent mounting frames 110.

[0050] In one possible implementation, such as Figure 12 As shown, the main body of each mounting frame 110 has a side-mounted "eye" shaped structure.

[0051] In one possible implementation, such as Figure 2 and Figure 3 As shown, there are six mounting frames 110 in total. The faces of the six mounting frames 110 are parallel to each other and arranged in a row. There are four connecting beams 120 between each two adjacent mounting frames 110.

[0052] Furthermore, the main body of the connecting beam 120 is a long, tubular structure. The length direction of all connecting beams 120 between each two adjacent mounting frames 110 is parallel to each other and perpendicular to the plane where the mounting frame 110 is located, thereby connecting two adjacent mounting frames 110 and making all mounting frames 110 a whole, ensuring uniform force distribution, and improving the structural strength and bearing capacity of the base 100.

[0053] The distance between two adjacent connecting beams 120 is adapted to the width of the main beam 800, ensuring that when the main beam 800 is placed on the base 100, the bottom side of the main beam 800 contacts the connecting beam 120, and the connecting beam 120 can effectively support the main beam 800.

[0054] In one possible implementation, each positioning component 200 includes: a positioning folding plate 210 and a first reinforcing rib 220; one side of the positioning folding plate 210 is fixedly connected to the base 100, and the other side of the positioning folding plate 210 is adapted to connect with the main beam 800 and the deck 900 of the armored vehicle chassis. Figure 10 As shown, the main body of the positioning folding plate 210 is a plate-shaped structure with a 90-degree bend. Multiple bolt holes 211 and 212 are provided on both sides of the positioning folding plate 210. Two first fixing blocks 230 are provided on the bottom surface of the positioning folding plate 210. The two first fixing blocks 230 are welded and fixed to both sides of the mounting frame 110 to clamp the middle mounting frame 110. Both first fixing blocks 230 have bolt holes 231, suitable for fixing to the positioning folding plate 210 above by bolt connection. The main body of the first reinforcing rib 220 is a triangular plate-shaped structure. The right-angled sides of the first reinforcing rib 220 are respectively connected to the right-angled inner sides of the positioning folding plate 210, which is suitable for improving the structural strength of the positioning folding plate 210 and preventing bending deformation.

[0055] Furthermore, such as Figure 1 and Figure 2 As shown, there are eight positioning components 200, arranged in pairs facing each other. The eight positioning components 200 are respectively mounted on the four mounting frames 110 located in the middle. Each mounting frame 110 has two positioning components 200 with their open sides facing each other. The distance between the two positioning components 200 on each mounting frame 110 is the same, so that the eight positioning components 200 are arranged in two parallel columns. The main beam 800 is placed on the base 100. The two columns of positioning components 200 respectively contact the two inner sides of the main beam 800. Eight points on the inner side of the main beam 800 are connected to the eight positioning components 200. The positioning plates 210 are fixedly connected to the side walls of the main beam 800 and the deck 900 by bolts. In this way, the eight positioning components 200 fix the eight points of the main beam 800 and the eight points of the deck 900, ensuring the installation stability of the main beam 800 and the deck 900 on the base 100 and improving the welding quality of the main beam 800 and the deck 900.

[0056] In one possible implementation, each gas spring support positioning part 300 includes an adjacently arranged flat plate positioning seat 310 and inclined plate positioning seat 320. For example... Figure 1 As shown, the flat plate positioning seat 310 and the inclined plate positioning seat 320 are installed adjacent to each other on the top of the base 100.

[0057] Furthermore, such as Figure 10 As shown, the flat plate positioning seat 310 includes: a first flat plate 313, a second flat plate 311, and a connecting plate 312; the first flat plate 313 and the second flat plate 311 are opposite to each other and parallel to the horizontal plane. The bottom of the first flat plate 313 is provided with two second fixing blocks 330, and the first flat plate 313 has two bolt holes 316; the connecting plate 312 is vertically disposed between the first flat plate 313 and the second flat plate 311, and the second flat plate 311 has two bolt holes 314, suitable for connection to the gas spring support 1000 by bolts. Two second reinforcing ribs 315 are provided between the connecting plate 312 and the first flat plate 313, and two third reinforcing ribs are also provided between the connecting plate 312 and the second flat plate 311 to improve the structural strength and load-bearing capacity of the flat plate positioning seat 310.

[0058] In one possible implementation, the base 100 is provided with auxiliary mounting beams 130, and auxiliary mounting beams 130 are also provided between the four mounting frames 110 in the middle. The length direction of the auxiliary mounting beams 130 is parallel to the length direction of the connecting beams 120. The flat plate positioning seat 310 is mounted on the auxiliary mounting beams 130, such as... Figure 10 and Figure 11As shown, the two second fixing blocks 330 at the bottom of the first plate 313 are welded and fixed to both sides of the auxiliary mounting beam 130 respectively; the bolt holes 331 of the second fixing blocks 330 are connected to the bolt holes 316 of the first plate 313 above by bolt connection.

[0059] Furthermore, such as Figure 3 As shown, each auxiliary mounting beam 130 is provided with an auxiliary rod 131 between itself and its adjacent connecting beam 120. The two ends of the auxiliary rod 131 are connected to the auxiliary mounting beam 130 and the connecting beam 120 respectively, thereby improving the installation stability of the auxiliary mounting beam 130.

[0060] Furthermore, the inclined plate positioning seat 320 includes: a third plate 323, an inclined plate 321, and an inclined beam 322. The third plate 323 is mounted on the mounting frame 110. Two third fixing blocks 340 are provided at the bottom of the third plate 323. The two third fixing blocks 340 are welded and fixed to opposite sides of the mounting frame 110. The bolt holes 341 of the third fixing blocks 340 are connected to the bolt holes 325 of the upper third plate 323 by bolts. The two ends of the inclined beam 322 are connected to the top surface of the third plate 323 and the inclined plate 321, respectively. The bolt holes 324 on the inclined plate 321 are suitable for connection to the gas spring support 1000 by bolts.

[0061] like Figure 4 As shown, the angle α between the length direction of the inclined beam 322 and the horizontal plane is 55°; the angle b between the plane containing the inclined plate 321 and the horizontal plane is 35°.

[0062] In one possible implementation, there are eight gas spring support positioning parts 300, arranged in pairs facing each other. For example... Figure 2 As shown, eight gas spring supports 1000 are arranged in two rows; eight inclined plate positioning seats 320 are respectively installed on the four middle mounting frames 110. Figure 3 As shown, there are six auxiliary mounting beams 130 in total. Two auxiliary mounting beams 130 are provided between each pair of adjacent four mounting frames 110 in the middle, and two connecting beams 120 are located between the two auxiliary mounting beams 130, so that the two rows of positioning components 200 are located between the two rows of oil and gas spring support positioning parts 300.

[0063] like Figure 3As shown, the six mounting frames 110 are defined from left to right as the first mounting frame 110 to the sixth mounting frame 110, for the following explanation: Two first side beams 140 are provided between the first mounting frame 110 and the second mounting frame 110, and the two ends of the two first side beams 140 are respectively connected to the two top corners of the first mounting frame 110 and the second mounting frame 110; Two second side beams 150 are provided between the third mounting frame 110 and the fourth mounting frame 110, and the two second side beams 150 are respectively connected to the two top corners of the third mounting frame 110 and the fourth mounting frame 110; Two third side beams 160 are provided between the fifth mounting frame 110 and the sixth mounting frame 110, and the two third side beams 160 are respectively connected to the two top corners of the fifth mounting frame 110 and the sixth mounting frame 110. Two first side beams 140 and two middle connecting beams 120 are used to support the placement of the rear base plate 1400; two second side beams 150 are used to support the placement of the middle base plate 1300; and two third side beams 160 and two middle connecting beams 120 are used to support the placement of the front base plate 1200.

[0064] Furthermore, such as Figure 3 As shown, the two connecting beams 120 located between the first mounting frame 110 and the second mounting frame 110 are each provided with a first reinforcing beam 121.

[0065] Furthermore, such as Figure 3 As shown, a second reinforcing beam 161 is provided between the two connecting beams 120 located between the fifth mounting frame 110 and the sixth mounting frame 110 and the two third side beams 160 on the side.

[0066] In one possible implementation, two or more first clamping members 600 protrude from one side of the base 100, and the first clamping members 600 and the support portion 400 are respectively located on adjacent side edges of the base 100; for example Figure 3 As shown, the top of the outermost mounting frame 110 (the first mounting frame 110) is provided with multiple first clamping members 600. The main body of the first clamping member 600 is a trapezoidal plate structure. The plane of the first clamping member 600 is perpendicular to the horizontal plane, and the plane of the first clamping member 600 is perpendicular to the plane of the mounting frame 110. The first clamping member 600 can support the rear base plate 1400. When the deck 900 is fastened to the beam 800, one side of the deck 900 contacts the first clamping member 600, thereby defining the position of the deck 900. Two or more first clamping members 600 are used to clamp one end of the deck 900 of the armored vehicle chassis.

[0067] Furthermore, there are a total of 7 first clamping components 600.

[0068] In one possible implementation, two or more second clamping members 700 protrude from one side of the base 100, and the second clamping members 700 and the first clamping members 600 are respectively located on opposite sides of the base 100. For example... Figure 3 As shown, the top of the other outermost mounting frame 110 (the sixth mounting frame) is provided with a plurality of second clamping members 700. The main body of the second clamping member 700 is a trapezoidal plate structure. The plane of the second clamping member 700 is perpendicular to the horizontal plane, and the plane of the second clamping member 700 is perpendicular to the plane of the mounting frame 110. The second clamping member 700 can support the front base plate 1200.

[0069] Furthermore, the second clamping element 700 has 10 parts.

[0070] In one possible implementation, the main body of the support 400 has a triangular structure. There are four support 400s in total, with two support 400s positioned between the second and third mounting frames 110, and the other two support 400s positioned between the fourth and fifth mounting frames 110. For example... Figure 15 As shown, the apex of each support 400 is adapted to support the position where the two semi-circular shells of each wheel 1100 are connected in the middle.

[0071] Furthermore, such as Figure 5 As shown, the angle c of the two support parts 400 near the first clamping member 600 is 124°; the angle d of the two support parts 400 near the second clamping member 700 is 98°.

[0072] like Figure 6 As shown, the top of the base 100 is provided with multiple pads 170.

[0073] The various components of the tooling in this application are fixed together by welding; the beam structure of the tooling is made of No. 10 channel steel; the plate structure of the tooling is made of Q235-A steel plate.

[0074] The working process of this application is described as follows:

[0075] 1. For example Figure 13 As shown, the main beam 800 is placed on the top surface of the base 100, so that the eight positioning components 200 are located inside the main beam 800 and in contact with the inner wall of the main beam 800.

[0076] 2. For example Figure 14 As shown, the deck 900 is fastened onto the main beam 800 and the position of the deck 900 is adjusted; then the eight positioning components 200, the two sides of the main beam 800 and the two sides of the deck 900 are connected and fixed with M16 bolts, thereby fixing the main beam 800 and the deck 900 together on the base 100.

[0077] 3. Install eight gas spring supports 1000 on eight gas spring support positioning parts 300 respectively. The gas spring supports 1000 are fixedly connected to the flat plate positioning seat 310 and the inclined plate positioning seat 320 by hexagonal head bolts.

[0078] 4. For example Figure 15 As shown, four wheel wells 1100 are placed on the base 100, and the middle part of the wheel well 1100 contacts the support part 400, so that the four support parts 400 effectively support the four wheel wells 1100.

[0079] 5. For example Figure 16 As shown, the front base plate 1200 is placed on the two third side beams 160, so that the second clamping member 700 clamps the front base plate 1200.
