Description

Technical Field

[0001] The utility model relates to the technical field of the body welding industry of rail transit, and particularly relates to a non-standard base for the welding of the skeleton of a high-speed train. Background Technique

[0002] In the existing rail transit industry, tooling fixtures, especially in the carbon steel vehicle industry, are basically mainly composed of jigs, or workbenches, threaded rods, and nut tightening structures. Without tooling fixtures, usually such welding generally has larger welds and greater thermal deformation. We need to select a sufficient pressing force, so this kind of support structure will not appear. Later, due to automation upgrades, this kind of support will appear when the jig changes from a jig to a fixture table workstation. Now, such structures mostly appear in the tooling fixtures of the car industry. The biggest difference between the two lies in the control of structural accuracy. In the car industry, it is generally a small amount of arc welding, or a large amount of spot welding and resistance welding, while in the rail transit industry, it is arc welding. The biggest characteristic of arc welding is thermal deformation. We need to select appropriate materials and thicknesses to ensure that the final welding quality meets the conditions;

[0003] The fixtures in cars are already very mature, and the structure of the welding fixtures in cars cannot be directly applied to the rail transit industry. The most important characteristic is that the welding method in cars is mainly resistance welding. In the fixtures of the same part size, compared with cars, the materials and thicknesses of all parts must be strengthened, so there are certain limitations in use. Content of the Utility Model

[0004] The purpose of the utility model is to provide a non-standard base for the welding of the skeleton of a high-speed train, so as to solve the problem proposed in the above background technique that the welding method in cars is mainly resistance welding. In the fixtures of the same part size, compared with cars, the materials and thicknesses of all parts must be strengthened.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A non-standard base for the welding of the skeleton of a high-speed train, including a fixture mounting plate, a fixture unit, and a non-standard base body;

[0006] The upper end surface of the fixture mounting plate is provided with a fixture unit, and the fixture unit has an accuracy of millimeters and below millimeters to ensure the accuracy and application range of subsequent robot welding;

[0007] The lower end surface of the fixture mounting plate is provided with a non-standard base body, and the direction and height of the fixture mounting plate are controlled through the non-standard base body. The design of the fixture unit determines whether it is easy to take out parts, and the most critical component of the overall strength of the fixture is the non-standard base for the welding of the skeleton of a high-speed train in this scheme, meeting its use requirements.

[0008] Furthermore, the non-standard base body is composed of a mounting connecting plate, a square steel pipe, a floor leveling support plate, a fence block, and a floor plate.

[0009] The lower end of the mounting connecting plate is installed with a square steel pipe, and the bottom of the square steel pipe is provided with a floor leveling support plate. The lower end of the floor leveling support plate is installed with a floor plate, and the upper end of the floor plate is fixedly connected with a fence block, and the inner side of the fence block is in contact with the outer side of the floor leveling support plate.

[0010] Furthermore, the mounting connecting plate, the square steel pipe and the floor leveling support plate are of a welded butt joint structure, and the mounting connecting plate is inclined when viewed from the front.

[0011] Furthermore, the inclination angle between the mounting connecting plate and the floor leveling support plate is 5°.

[0012] Furthermore, the fence block and the floor plate are of a welded integrated structure, and 4 fence blocks are arranged at equal angles with respect to the center point of the floor plate, and the 4 fence blocks are combined into a rectangular state structure.

[0013] Furthermore, the positions of the floor leveling support plate and the 4 fence blocks correspond to each other, and the floor leveling support plate is butt-jointed with the floor plate and the fence block by welding.

[0014] Furthermore, the floor plate is square when viewed from above, and the area of the floor plate is larger than the areas of the floor leveling support plate and the square steel pipe.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. For the non-standard base used for the welding of the high-speed train skeleton, the existence of this product is to connect the structure between the ground and the fixture mounting plate. Each part of the overall fixture has similarities or the same functions, and this component will affect the overall practicability. When manually operating the fixture, it meets the requirement of reaching a suitable human-machine height. When workers operate the fixture, due to thermal deformation, it is avoided that some parts are not easily taken out. The design of the fixture unit determines whether it is easy to take out the parts, and the most critical component of the overall strength of the fixture is the non-standard base used for the welding of the high-speed train skeleton in this scheme, which meets its use requirements;

[0017] 2. For the non-standard base used for the welding of the high-speed train skeleton, the existence of this product is to connect the structure between the ground and the fixture mounting plate, and there are strict requirements for it. It is provided with a suitable angle, a suitable height, a suitable strength, a necessary flatness, and a simple operation adjustment method for the required flatness, so as to meet the overall operation requirements.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1 - 6 , the present utility model provides a technical solution: a non-standard base for the welding of the high-speed train skeleton, including a non-standard base body 1, an installation connecting plate 101, a square steel pipe 102, an anchor foot leveling support plate 103, a fence block 104, and an anchor plate 105.

[0027] In the first embodiment:

[0028] A fixture unit is installed on the upper end surface of the fixture mounting plate. The fixture unit has an accuracy of millimeters and below millimeters to ensure the accuracy and applicable range of subsequent robot welding;

[0029] The lower end surface of the fixture mounting plate is provided with a non-standard base body 1, and the direction and height of the fixture mounting plate are controlled by the non-standard base body 1.

[0030] The above three structures form a welding fixture. Among them, the fixture unit has an accuracy of millimeters and below. Such accuracy also ensures the accuracy and applicable range of subsequent robot welding. The fixture mounting plate is the position where all fixture units are installed, and all mounting holes are uniformly drilled on it. Generally, it needs to be machined at one time by a numerically controlled three-axis high-precision machine tool, including the holes on the reverse side of the base. After conversion of the flipping accuracy, it also needs to be machined at one time, so that the accuracy of all fixture units can be guaranteed. The accuracy of all units is independent, so a fixture mounting plate with relatively high accuracy is required. The direction is completed by the fixture base. After the final positioning of the fixture base, it will be welded in place. Basically, within the product life cycle of a vehicle body, this weld is not allowed to be damaged. Once there is a requirement for displacement, the fixture needs to be leveled again, and all fixture units also need to be measured by a coordinate measuring machine before they can continue to work;

[0031] In the second embodiment:

[0032] The difference from the first embodiment lies in:

[0033] The non-standard base body 1 is composed of a mounting connecting plate 101, a square steel pipe 102, a floor leveling support plate 103, a fence block 104, and a floor plate 105; the lower end of the mounting connecting plate 101 is installed with the square steel pipe 102, and the bottom of the square steel pipe 102 is provided with the floor leveling support plate 103. The lower end of the floor leveling support plate 103 is installed with the floor plate 105, and the upper end of the floor plate 105 is fixedly connected with the fence block 104, and the inner side of the fence block 104 is in contact with the outer side of the floor leveling support plate 103.

[0034] The mounting connecting plate 101, the square steel pipe 102, and the floor leveling support plate 103 are of a welded butt joint structure, and the mounting connecting plate 101 is inclined when viewed from the front. The inclination angle between the mounting connecting plate 101 and the floor leveling support plate 103 is 5°. The fence block 104 and the floor plate 105 are of a welded integrated structure, and 4 fence blocks 104 are arranged at equal angles with respect to the center point of the floor plate 105, and the 4 fence blocks 104 are combined into a rectangular state structure.

[0035] The positions of the floor leveling support plate 103 and the 4 fence blocks 104 correspond to each other, and the floor leveling support plate 103 is butt-jointed with the floor plate 105 and the fence block 104 by welding. The floor plate 105 is square when viewed from above, and the area of the floor plate 105 is larger than the areas of the floor leveling support plate 103 and the square steel pipe 102

[0036] Among them, the installation connecting plate 101, the square steel pipe 102, and the anchor leveling support plate 103 are welded connectors, and the fence block 104 and the anchor plate 105 are welded connectors. The two welded parts cannot be connected during the pre-installation of the fixture. Overall leveling is required. When the equipment arrives at the site, first, it is necessary to draw lines to determine the position of the fixture, and place the fixture according to the above structure. At this time, the fixture is not yet leveled. The dimensions, reference, and the reference of the robot after leveling are in the same direction. After leveling, we weld the two welded parts together. In future production, if the fixture shifts, the leveling work needs to be readjusted and replaced.

[0037] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
