Description

Technical Field

[0001] This utility model relates to tooling and molds, specifically to a special vehicle wheel rim welding anti-deformation tooling. Background Technology

[0002] Armored vehicles are special vehicles with armor protection. Their hulls have multiple wheel arches along the longitudinal direction corresponding to the track wheels or treadle wheels. When fixing the wheel arches at the hull welding station, the process is: wheel arch pre-assembly → wheel arch pre-welding → hull assembly → wheel arch welding. If no anti-deformation measures are taken at the welding points during wheel arch welding, and welding is performed in a natural state, the following problems will occur: 1. The wheel arch spacing shrinks and deforms after welding, and the amount of deformation is inconsistent for each group of wheel arch spacing, resulting in different final spacing dimensions. This causes the wheel arch spacing dimensions to not meet the design requirements when assembling the axle at the final assembly station, making axle assembly impossible.

[0003] 2. In order to ensure the reliability of the wheel rim, the wheel rim is usually fully welded. The weld is long and continuous, which may lead to uncontrollable welding deformation and fail to meet the requirements of mass production.

[0004] 3. For armored vehicles that emphasize battlefield survivability and protection, the wheel hulls are typically made of high-strength materials. For example, the wheel hulls of a certain armored vehicle use armor steel plate 22SiMn2TiB with a thickness of not less than 6mm. Because the wheel hulls use relatively thick armor steel plates, their toughness is high, and it is difficult to restore them to the required dimensions after deformation through correction or other methods.

[0005] Therefore, designing a welding fixture to prevent deformation of wheel rims on special vehicles is of great practical significance. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a special vehicle wheel arch welding anti-deformation tooling that can provide support and limit the left and right wheel arches, ensure that the wheel arch spacing dimensions meet the design requirements, and ensure that the welding deformation of the left and right wheel arches meets the requirements without the need for post-weld correction.

[0007] This utility model discloses a special vehicle wheel hub welding anti-deformation tooling, comprising a rod, a first support member, an adapter plate, and a second support member. The first support member and the adapter plate are respectively disposed at different ends of the rod, and the second support member is detachably connected to the adapter plate. A first wheel hub contact surface is provided on the side of the first support member facing away from the second support member, and a plurality of first wheel hub positioning components are arranged at intervals on the first wheel hub contact surface. A second wheel hub contact surface is provided on the side of the second support member facing the first support member, and a plurality of second wheel hub positioning components are arranged at intervals on the second wheel hub contact surface.

[0008] Furthermore, the second support member includes a connecting frustum and a flange. The connecting frustum is detachably connected to the adapter plate. The flange is located on the side of the connecting frustum facing away from the adapter plate. The flange protrudes radially outward from the connecting frustum, and the second wheel hub mating surface is located on the flange.

[0009] Furthermore, the connecting platform is provided with a plurality of threaded holes at intervals, and the adapter plate is provided with bolt through holes at the positions corresponding to the plurality of threaded holes; a plurality of third bolts pass through the bolt through holes and are connected to the corresponding threaded holes, so as to realize the detachable connection between the connecting platform and the adapter plate.

[0010] Furthermore, the opposing surfaces of the connecting frustum and the adapter plate are both planes.

[0011] Furthermore, a weight-reducing groove is provided in the middle of the second support member.

[0012] Furthermore, multiple first-round package positioning components and multiple second-round package positioning components are all threaded fastening components.

[0013] Furthermore, the plurality of first wheel hub positioning components include a first bolt and a first nut sleeved on the first bolt, and the first wheel hub mating surface is provided with a plurality of first mounting holes for the first bolt to pass through.

[0014] Furthermore, the plurality of second wheel hub positioning components include a second bolt and a second nut sleeved on the second bolt, and the second wheel hub mating surface is provided with a plurality of second mounting holes for the second bolt to pass through.

[0015] Furthermore, the lower part of the first support member is provided with an avoidance notch.

[0016] Furthermore, both the first support member and the adapter plate are fixedly connected to the rod body by welding.

[0017] The beneficial effects of this utility model are: (1) This utility model can provide support and limit the left and right wheel arches during wheel arch welding. On the one hand, it can ensure that the distance between the left and right wheel arches does not change, so that the wheel arch spacing size does not shrink or deform after welding, thereby ensuring that the spacing size between each group of left and right wheel arches is the same, ensuring that the wheel arch spacing size meets the requirements when assembling the axle at the final assembly station, and thus ensuring the normal assembly of the axle. On the other hand, the tooling can suppress the welding deformation of the left and right wheel arches, ensuring that the welding deformation of the left and right wheel arches meets the requirements, and eliminating the need for post-weld correction.

[0018] (2) The present invention reduces the total length of the tooling by using a detachable second support member, which ensures that the total length of the tooling after the second support member is removed is less than the wheel arch distance, thereby ensuring that the overall structure composed of the rod, the first support member, and the adapter plate can be hoisted into the vehicle body.

Detailed Implementation

[0021] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1-5 As shown, a special vehicle wheel hub welding anti-deformation tooling in this embodiment includes a rod 10, a first support member 20, an adapter plate 30, and a second support member 40. The first support member 20 and the adapter plate 30 are respectively disposed at different ends of the rod 10. The second support member 40 is detachably connected to the adapter plate 30. A first wheel hub contact surface 21 is provided on the side of the first support member 20 facing away from the second support member 40, and a plurality of first wheel hub positioning components are spaced apart on the first wheel hub contact surface 21. A second wheel hub contact surface 41 is provided on the side of the second support member 40 facing the first support member 20, and a plurality of second wheel hub positioning components are spaced apart on the second wheel hub contact surface 41.

[0023] The armored vehicle hull has multiple sets of wheel arches along the front-to-back direction corresponding to the positions of the track wheels or wheels. When fixing the wheel arches at the hull welding station, the process is as follows: wheel arch pre-assembly → wheel arch pre-welding → hull assembly → wheel arch welding.

[0024] Before welding the wheel arches, firstly, after removing the second support member 40, the total length of the tooling is less than the wheel arch spacing. The integrated structure consisting of the rod body 10, the first support member 20, and the adapter plate 30 is then hoisted into the body of the special vehicle (e.g., an armored vehicle) using a hoisting device, and aligned with the positions of one set of pre-welded left wheel arches 50 and right wheel arches 60. Then, the first support member 20 is connected to the right wheel arch 60 using the first wheel arch positioning assembly. Finally, the connecting frustum 42 of the second support member 40 is passed through the central hole of the left wheel arch 50 from outside the vehicle body, and the second support member 40 is connected to the adapter plate 30 using the second wheel arch positioning assembly, completing the preparation work for wheel arch welding. At this time, the first wheel pack bonding surface 21 abuts against the right wheel pack 60, and the second wheel pack bonding surface 41 abuts against the left wheel pack 50. Since the pre-welded left wheel pack 50 and right wheel pack 60 have a certain load-bearing capacity, the tooling will not fall off the vehicle body as a whole after it is connected to the left wheel pack 50 and right wheel pack 60.

[0025] After the preparation work for wheel arch welding is completed, wheel arch welding is carried out. The joints between the left wheel arch 50 and the vehicle body, and the joints between the right wheel arch 60 and the vehicle body are welded using a full welding method. After welding is completed, the second support member 40 is removed, and the integrated structure consisting of the rod 10, the first support member 20, and the adapter plate 30 is moved to carry out the welding of another set of pre-welded wheel arches, the left wheel arch 50 and the right wheel arch 60.

[0026] As can be seen from the above, the detachable second support member 40 can reduce the total length of the tooling, ensuring that the total length of the tooling after the second support member 40 is removed is less than the wheel arch distance, thereby ensuring that the overall structure composed of the rod 10, the first support member 20, and the adapter plate 30 can be hoisted into the vehicle body.

[0027] During wheel arch welding, the first wheel arch positioning assembly connects the first support 20 to the right wheel arch 60, and the second wheel arch positioning assembly connects the second support 40 to the adapter plate 30. Furthermore, the first wheel arch mating surface 21 abuts against the right wheel arch 60, and the second wheel arch mating surface 41 abuts against the left wheel arch 50. Therefore, the tooling provides support and limits for the left wheel arch 50 and right wheel arch 60. On one hand, it ensures that the distance between the left wheel arch 50 and right wheel arch 60 remains unchanged, preventing shrinkage or deformation of the wheel arch pitch after welding. This ensures that the pitch dimensions of each set of left wheel arch 50 and right wheel arch 60 are identical, guaranteeing that the wheel arch pitch dimensions meet design requirements when assembling the axle at the final assembly station, thus ensuring the normal assembly of the axle. On the other hand, the tooling suppresses the welding deformation of the left wheel arch 50 and right wheel arch 60, ensuring that the welding deformation of the left wheel arch 50 and right wheel arch 60 meets the requirements, eliminating the need for post-weld correction.

[0028] In this embodiment, the second support member 40 includes a connecting frustum 42 and a flange 43. The connecting frustum 42 is detachably connected to the adapter plate 30. The flange 43 is disposed on the side of the connecting frustum 42 facing away from the adapter plate 30. The flange 43 protrudes radially outward from the connecting frustum 42. The second wheel hub mating surface 41 is located on the flange 43.

[0029] The outer diameter of the connecting frustum 42 is no greater than the inner diameter of the central hole of the left wheel arch 50. After the connecting frustum 42 passes through the central hole of the left wheel arch 50 from outside the vehicle body and abuts against the adapter plate 30, the second support 40 is connected to the adapter plate 30 through the second wheel arch positioning assembly. At this time, the flange 43 is located outside the vehicle body, and the second wheel arch contact surface 41 of the flange 43 abuts against the outer wall of the left wheel arch 50, providing support and limiting for the left wheel arch 50.

[0030] In this embodiment, the connecting frustum 42 is provided with a plurality of threaded holes 44 at intervals, and the adapter plate 30 is provided with bolt through holes 31 corresponding to the positions of the plurality of threaded holes 44; a plurality of third bolts 32 pass through the bolt through holes 31 and are connected to the corresponding threaded holes 44, so as to realize the detachable connection between the connecting frustum 42 and the adapter plate 30. In this embodiment, the facing surfaces of the connecting frustum 42 and the adapter plate 30 are both planes.

[0031] The connecting platform 42 and the adapter plate 30 are detachable, and both of their facing sides are flat, allowing a pad or shim to be placed between the connecting platform 42 and the adapter plate 30. This enables the tooling to be applicable to car bodies with different wheel arch lengths, improving the tooling's versatility.

[0032] Each shim or pad has a through hole corresponding to the bolt through hole 31. The third bolt 32 passes through the bolt through hole 31 of the adapter plate 30 and the through hole of the shim or pad, and then is threaded into the threaded hole 44 of the connecting frustum 42, thus installing the connecting frustum 42. Of course, it is also possible to connect the connecting frustum 42 directly to the adapter plate 30 without using a shim or pad. The steps for disassembling the connecting frustum 42 are the reverse of the installation steps, and will not be described here.

[0033] In this embodiment, a weight-reducing groove 45 is provided in the middle of the second support member 40. The weight-reducing groove 45 can not only reduce the weight of the tooling, but also reduce the weight difference between the left and right sides of the tooling.

[0034] In this embodiment, the multiple first-round bag positioning components and the multiple second-round bag positioning components are all threaded fastening components.

[0035] In this embodiment, the plurality of first wheel hub positioning components include a first bolt 22 and a first nut 23 sleeved on the first bolt 22, and the first wheel hub mating surface 21 is provided with a plurality of first mounting holes for the first bolt 22 to pass through.

[0036] The position of the first mounting hole on the first wheel cover 21 corresponds to the hole on the right wheel cover 60. After the first bolt 22 passes through the first mounting hole and the hole on the right wheel cover 60, it is threaded to the first nut 23. After tightening each of the first nuts 23, the connection between the first support member 20 and the right wheel cover 60 is achieved. The first mounting hole can be a screw hole or a through hole.

[0037] In this embodiment, the plurality of second wheel pack positioning components include a second bolt 46 and a second nut 47 sleeved on the second bolt 46, and a plurality of second mounting holes 48 for the second bolt 46 to pass through are provided at intervals on the second wheel pack mating surface 41.

[0038] The position of the second mounting hole 48 on the second wheel cover's mating surface 41 corresponds to the built-in hole on the left wheel cover 50. After the second bolt 46 passes through the second mounting hole 48 and the built-in hole on the left wheel cover 50, it is threadedly connected to the second nut 47. After tightening all the second nuts 47, the connection between the second support member 40 and the left wheel cover 50 is achieved. The second mounting hole 48 can be a screw hole or a through hole.

[0039] In this embodiment, the lower part of the first support member 20 is provided with an avoidance notch 24, which can prevent the tooling from interfering with the components of the vehicle body.

[0040] In this embodiment, the first support member 20 and the adapter plate 30 are both fixedly connected to the rod body 10 by welding. After the rod body 10, the first support member 20 and the adapter plate 30 are fixedly connected by welding, their relative positions are fixed.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
