Technical Field

[0001] The utility model belongs to the technical field of rail vehicles, and in particular relates to a pre-assembly welding tool for an air-conditioning well on the roof of a monorail vehicle. Background Art

[0002] Monorail car roof air conditioning well pre-assembly (its product structure is as follows Figure 6 As the main load-bearing area of ​​the entire roof, it has high structural strength requirements and is the basis for the later assembly of air-conditioning equipment. The accuracy of its welding dimensions determines the assembly dimensions of subsequent air-conditioning equipment and the machining quality of corresponding machining items, which in turn affects the final product quality of the entire monorail car roof.

[0003] Normally, the production of conventional riveted and welded parts for rail vehicles is carried out by positioning and welding on a welding platform. However, this method is not suitable for the welding of pre-assemblies of roof air-conditioning wells, which have very high requirements. It is not easy to control the welding size, weld quality and product deformation after welding.

[0004] In addition, commonly used tooling only constrains and controls the conventional shape tolerance of the product, while the tooling for the pre-assembly of the air-conditioning well on the roof of the monorail vehicle needs to consider issues such as controlling the welding dimensions, the straightness and position tolerance of the product after welding, and the consistency of batch product production in the tooling design.

[0005] In addition, it is also necessary to consider the low welding efficiency and high labor intensity of the assembly welding of the roof air conditioning well pre-assembly.

[0006] Therefore, it is necessary to design a welding tool for the pre-assembly of the roof air conditioning well to solve the above problems. Summary of the invention

[0007] In view of the shortcomings and deficiencies in the prior art, the purpose of the utility model is to provide a monorail vehicle roof air-conditioning well pre-assembly welding tooling, which can ensure the dimensional control of the technical requirements of the monorail vehicle roof air-conditioning well pre-assembly, and ultimately ensure the later assembly quality of the monorail vehicle roof.

[0008] The technical solution of the utility model is as follows:

[0010] Furthermore, the base includes a rectangular tube, a steel plate and a cantilever clamp mounting seat. The rectangular tubes are spliced ​​together to form a rectangular frame. The steel plate is arranged on the working surface of the rectangular frame. The cantilever clamp mounting seat is arranged on the inner side surface of the rectangular frame. The cantilever clamp mounting seat is provided with holes.

[0011] Furthermore, a plurality of rectangular tubes are additionally arranged in the rectangular frame for reinforcing support.

[0012] Furthermore, after welding, the rectangular frame is processed as a whole to ensure the overall flatness of the working surface.

[0013] Furthermore, the quick pressing device includes a plug-in end, a connecting end and a pressing end; the plug-in end and the pressing end are parallel to each other and vertically connected together through the connecting end, and the bottom of the plug-in end is inserted into the hole of the cantilever clamp mounting seat; the pressing end moves up and down and quickly presses the monorail vehicle roof air-conditioning well pre-assembly through a thread.

[0014] Furthermore, the clamping end is provided with a thread to match and connect with the corresponding end of the connecting end.

[0015] Furthermore, the plug end can rotate 360° around the hole of the cantilever presser mounting base.

[0016] Furthermore, the connection part includes a positioner interface and a base interface, the positioner interface and the base interface are arranged back to back, the base interface is welded to the base frame, and the positioner interface is arranged outwardly and docked and fixed with the self-contained installation interface of the positioner.

[0017] Furthermore, the connection part is made of welded steel. The beneficial effects of the utility model are:

[0018] (1) By utilizing the utility model of the monorail vehicle roof air conditioning well pre-assembly welding fixture, the roof air conditioning well pre-assembly welding fixture itself and the positioner are combined to complete the one-time welding of the roof air conditioning well pre-assembly, thereby reducing the cumulative tolerance of multiple clamping. In addition, after the welding, the fixture is processed and formed by a CNC machine tool in one time, and the straightness position tolerance is 0.05mm. The precision of the fixture can be used to control the position tolerance of the roof air conditioning well pre-assembly.

[0019] (2) By changing the tooling and product direction through the positioner, multiple manual turning can be avoided, thus improving production efficiency.

[0020] The use of mechanical equipment to assist in displacement makes it safe and reliable, reduces the labor intensity of operators and improves safety.

[0021] (3) The use of an adjustable quick clamping device can prevent reverse deformation after welding, improve product consistency and control product quality, and reduce the workload of product adjustment.

[0022] The quick clamping device is a vulnerable and consumable part and is installed by plug-in. The subsequent replacement and maintenance are convenient, reducing tooling maintenance costs.

[0023] (4) The utility model is used to utilize the pre-assembly welding fixture of the monorail vehicle roof air conditioning well, and an adjustable longitudinal and transverse positioning device is adopted to quickly meet the size adjustment, reduce manual measurement, and ensure product consistency.

[0024] (5) The utility model monorail vehicle roof air conditioning well pre-assembly welding tooling has a reasonable design and a compact structure; no additional working platform is required, and installation, disassembly and use are flexible and convenient, and the service life is long.
