Description

Technical Field

[0001] The utility model relates to the technical field of automobile bodies, in particular to a top equipment installation platform for a cab. Background Art

[0002] In order to meet the requirement of installing an electronic device on the top of the cab, the flatness of the installation plane of this device is required to be no greater than 0.5 mm, and the thickness of the installation surface shall not be less than 6 mm. Considering that the installation area is about 1300×1200 mm and such a high flatness standard needs to be achieved, it is obviously not feasible to directly fix the bracket to the vehicle roof by welding, because this is likely to cause deformation due to welding, thus unable to guarantee the required plane accuracy. To solve this problem, an installation platform is needed to isolate the influence of the deformation caused during the welding process on the final installation surface, ensuring that the strict flatness requirements can be met. Summary of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a top equipment installation platform for a cab to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A top equipment installation platform for a cab includes a vehicle roof, a vehicle roof skeleton, a threaded seat welding tooling, countersunk bolts, a machining platform, a special flatness gauge, and copper foil gaskets. The vehicle roof skeleton is arranged below the vehicle roof according to the projection position of the machining platform. The threaded seat is connected to the horizontally positioned threaded seat welding tooling through countersunk bolts. The threaded seat welding tooling welds a plurality of threaded seats to the vehicle roof skeleton. The machining platform is connected to the threaded seat through countersunk bolts. A copper foil gasket is provided between the machining platform and the threaded seat. The special flatness gauge accurately measures the flatness of the machining platform.

[0006] Preferably, the threaded seat welding tooling adopts a diagonal welding sequence to reduce welding deformation.

[0007] Preferably, the flatness of the machining platform is less than 0.5 mm.

[0008] Preferably, the material of the machining platform is Q345 steel plate.

[0009] Preferably, the head of the threaded seat extends out of the vehicle roof and is connected to the countersunk bolt.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. Improve installation accuracy: The machined platform is fixed to the roof through screw connection technology, effectively avoiding the thermal deformation problems that may occur during traditional welding. This ensures that the flatness of the installation platform can be accurately controlled within 0.5 mm, meeting the installation requirements of high-precision equipment.

[0012] 2. Simplify the construction process: Use prefabricated threaded seats and supporting tooling for on-site assembly, greatly simplifying the traditional work steps that require a large amount of manual adjustment, reducing the operation difficulty and time cost, and improving work efficiency.

[0013] 3. Enhance structural stability: By reasonably designing the connection method between the roof skeleton and the threaded seat (such as diagonal welding), not only the stability of the entire support system is enhanced, but also the risk of overall offset caused by uneven local stress is reduced.

[0017] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following combines the drawings and preferred embodiments to detail the specific implementation manner, structure, features and their effects of the present utility model as follows.

[0018] Such as Figure 1-2A top equipment installation platform for a cab, comprising a machining platform 1, a threaded seat 2, a copper foil gasket 3, a countersunk head bolt 4, a roof frame 5, a roof 6, a threaded seat welding tooling (not shown), and a special flatness gauge (not shown). The roof frame 5 is arranged below the roof 6 according to the projection position of the machining platform 1. To reduce welding deformation, a threaded seat welding tooling is designed. The welding tooling is lifted to the roof 6 by a crane, and the threaded seat welding tooling is adjusted to a horizontal position using a spirit level. The threaded seat 2 is connected to the threaded seat welding tooling by the countersunk head bolt 4. The threaded seat welding tooling welds multiple threaded seats 2 to the roof frame 5 in a diagonal welding sequence. The machining platform 1 is connected to the threaded seat 2 by the countersunk head bolt 4. A copper foil gasket 3 is provided between the machining platform 1 and the threaded seat 2. The special flatness gauge accurately measures the flatness of the machining platform 1. The flatness of the machining platform 1 is less than 0.5 mm. The material of the machining platform 1 is Q345 steel plate or other materials with good mechanical properties and low thermal expansion coefficients. Equipment installation threaded holes 7 are provided on the machining platform 1.

[0019] Usage principle:

[0020] Arrange the roof frame at the top according to the projection position of the machining platform. Connect all the threaded seats to the threaded seat welding tooling with countersunk head bolts, then weld all the threaded seats to the roof frame in a diagonal welding sequence. Then remove the threaded seat welding tooling. Connect the machined machining platform to the roof threaded seats with countersunk head bolts. Use the special flatness gauge to check the flatness of the installation platform. If there are areas where the flatness is greater than the specified value, adjust by increasing or decreasing the number of copper foil gaskets until the flatness of the installation plane meets the installation requirements.
