The present application is described below with reference to the accompanying drawings and specific embodiments:

Please refer to Figure 1. In an embodiment of the present application, an auxiliary tooling of a weighing mechanism mounting seat is provided, which is used to assist the assembly of the weighing mechanism mounting seat 400 on a vehicle. When installing the weighing mechanism, the weighing mechanism mounting seat 400 is first fixed to the auxiliary tooling 100, and then the weighing mechanism mounting seat 400 is fixed to the bottom of the vehicle through the auxiliary tooling 100. The vehicle is a train, and can also be other vehicle structures. The groove structure 200 at the bottom of the vehicle is a groove at the middle beam at the bottom of the train. The fixed structure 300 at the bottom of the vehicle is a core plate next to the middle beam at the bottom of the train. The groove structure 200 and the fixed structure 300 can also be other structures of the vehicle, as long as they are formed into a groove shape and fixed to the vehicle; the auxiliary tooling 100 includes: an assembly main board 110, a first stopper 120 and a second stopper 130; an assembly main board 110 is in the shape of a plate and is made of 3mm thick steel plate. The assembly mainboard 110 is used to fix and support the weighing mechanism mounting seat 400. The weighing mechanism mounting seat 400 and the assembly mainboard 110 are detachably connected, can be firmly fixed to each other and are easy to disassemble. For example, the weighing mechanism mounting seat 400 and the assembly mainboard 110 are both provided with corresponding threaded holes, and the weighing mechanism mounting seat 400 and the assembly mainboard 110 can be fixed with bolts or screws; in an optional embodiment, the weighing mechanism mounting seat 400 and the assembly mainboard 110 can adopt a snap-on, plug-in or other structural form that is convenient for connection and disassembly, such as using an existing conventional snap-on in a notch or bent shape on the edge of the assembly mainboard 110, and connecting the edge of the assembly mainboard 110 to the weighing mechanism mounting seat 400 through a snap-on.

Referring to FIG. 2 , the first stopper 120 is connected to the assembly main board 110 by welding, bolting or other connection methods. The first stopper 120 is in the shape of a block, a plate or a strip, and other structural forms may also be adopted. The first stopper 120 is used to be positioned in the groove structure 200 at the bottom of the vehicle. If the first stopper 120 adopts a block structure, the width of the first stopper 120 is consistent with the width of the inner wall of the groove of the middle beam, so that the first stopper 120 can be stuck in the groove structure 200 of the middle beam and stably fixed; the second stopper 130 is connected to the assembly main board 1 10. The second stopper 130 is fixed to the assembly main board 110 and cannot move relative to it. It is connected by welding, bolting or other methods. The second stopper 130 is used to abut against the outer edge of the fixed structure 300 at the bottom of the vehicle. The fixed structure 300 is located on the outside of the groove structure 200. The fixed structure 300 is the core plate of the bottom of the vehicle. The second stopper 130 is in the shape of a block, plate or strip, and other structural forms can also be used, as long as it can ensure that the second stopper 130 abuts against the core plate and determine the relative position of the assembly main board 110 and the core plate.

The prior art does not have any tool to assist in installing the weighing mechanism mounting seat 400. During the installation of the prior weighing mechanism mounting seat 400, the assemblers completely rely on manual marking. Since it is installed in the groove of the center beam at the bottom of the vehicle, the light is dim and the operator needs to look up to work. The manual marking is not accurate, and the horizontal and vertical degrees are difficult to ensure. There are errors in the installation position. After the marking is completed, the assemblers hold the weighing mechanism mounting seat 400 according to the marked position and then weld it to fix it. Therefore, it is easy to cause the position deviation and tilt of the weighing mechanism, affecting the normal use of the automatic adjustment device for the empty and loaded vehicle, and it is inconvenient to operate, causing operational safety problems.

The present application forms an integral body of the weighing mechanism mounting seat 400 and the auxiliary tooling 100 by fixing the assembly main board 110 with the weighing mechanism mounting seat 400. The weighing mechanism mounting seat 400 is not convenient for direct precise positioning and installation, so the problem is converted into positioning and installation of the auxiliary tooling 100. The first stopper 120 can be positioned in the groove structure 200 at the bottom of the vehicle, so that the position of the assembly main board 110 and the groove structure 200 at the bottom of the vehicle is determined, thereby limiting the freedom of the above-mentioned mounting seat 400 relative to the two sides of the groove structure 200. The second stopper 130 can be abutted against the fixed structure 300 at the bottom of the vehicle, so that the assembly main board 110 and the vehicle The position of another reference object at the bottom is determined, thereby limiting the freedom of the above-mentioned mounting seat 400 in another direction. By directly or indirectly abutting the assembly mainboard 110 against the bottom of the vehicle, the above-mentioned mounting seat 400 is made parallel to the bottom of the vehicle and the position is determined, thereby limiting the freedom of the above-mentioned mounting seat 400 in the vertical direction. The position of the mounting seat 400 of the weighing mechanism can be determined by the auxiliary tooling 100. In this way, the mounting seat 400 of the weighing mechanism can be accurately positioned, and the mounting seat 400 of the weighing mechanism can be installed and fixed at one time without repeated disassembly and assembly, which significantly improves the quality of the installation completion, and can ensure the normal use of the automatic adjustment device for the empty and loaded vehicle, thereby ensuring the driving safety of the vehicle.

Referring to FIG. 3 , in an optional embodiment, at least two first stoppers 120 are provided, and the plurality of stoppers can provide a plurality of limiting points, so that the position of the assembly main board 110 can be positioned more accurately, and the plurality of first stoppers 120 are relatively arranged so that the ends of the plurality of first stoppers 120 can respectively abut against the relative positions of the inner wall of the groove structure 200 at the bottom of the vehicle; if two first stoppers 120 are used, the first stoppers 120 are rod-shaped or sheet-shaped, and the first stoppers 120 are fixed to the assembly main board 110, and the ends of the first stoppers 120 are at the assembly main board 110. The side surfaces of the distribution main board 110 extend outward and face the two sides of the assembly main board 110. The setting of the first stopper 120 makes the end of the assembled weighing mechanism mounting seat 400 108 mm away from the inner wall of the groove of the center beam, and can also be other distances; when positioning, the assembly main board 110 fixes the weighing mechanism mounting seat 400 to the bottom of the vehicle, and at the same time, the two first stoppers 120 extend into the groove structure 200, and the ends of the first stoppers 120 are just in the relative position against the groove, and the assembly main board 110 will not produce positioning deviation in the directions on both sides of the center beam.

Please refer to FIG. 4 , in an optional embodiment, the first stopper 120 is bent, and the first stopper 120 has two opposite ends, one end of the first stopper 120 is connected to the board surface of the assembly main board 110, and the other end of the first stopper 120 is bent toward the groove structure 200, and the first stopper 120 is in a long strip shape and is in a bent shape. The extension directions of the two ends of the first stopper 120 are at an angle to each other, and the angle can be set as needed, such as a right angle, an obtuse angle, and the first stopper 120 is bent at a position close to the assembly main board 110. The first stopper 120 is folded and arranged, one end of the first stopper 120 is welded and fixed to the assembly main board 110, and the other end of the first stopper 120 is bent and faces the two sides of the assembly main board 110. When the weighing mechanism mounting base 400 is positioned by the assembly main board 110, the other end of the first stopper 120 can be abutted against the inner wall of the groove structure 200. Specifically, at the relative inner wall position in the groove of the middle beam, the end of a part of the first stopper 120 is abutted and fixed against the inner wall of the groove, and the end of another part of the first stopper 120 is abutted and fixed against the opposite inner wall of the groove.

Please refer to Figures 5 and 6. In an optional embodiment, the assembly mainboard 110 has a first plate surface and a second plate surface relative to each other, i.e., the front and back sides of the assembly mainboard 110. The first stopper 120 is connected to the first plate surface. The assembly mainboard 110 can be fixed to the weighing mechanism mounting seat 400 through the first plate surface, i.e., the connection between the first plate surface and the weighing mechanism mounting seat 400 is located on the same plane. The edge of the weighing mechanism mounting seat 400 can abut against the connection angle between the first stopper 120 and the assembly mainboard 110 on the first plate surface, which facilitates more precise positioning of the weighing mechanism mounting seat 400. The first plate surface faces upward when the weighing mechanism mounting seat 400 is installed, so that the weighing mechanism mounting seat 400 is supported on the bottom of the vehicle by the first plate surface of the assembly mainboard 110 and is positioned by the first stopper 120 at the same time. In an optional embodiment, the assembly mainboard 110 is in the shape of a square plate, and each corner of the assembly mainboard 110 is transitioned through a rounded corner. The four corners of the assembly mainboard 110 are rounded with a radius of 10 mm to avoid scratches on personnel and facilitate assembly. The assembly mainboard 110 can also adopt other shapes, such as a circle, a diamond, etc.

Please refer to Figure 7, in an optional embodiment, a third stopper 140 is further included. The third stopper 140 is in a block, plate or strip shape. The third stopper 140 is arranged on the first board surface of the assembled mainboard 110. The third stopper 140 is welded and fixed to the assembled mainboard 110, or is bolted, screwed or the like. For example, the third stopper 140 is a strip structure and is welded to the first board surface of the assembled mainboard 110. Relative to the connection between the first stopper 120 and the assembled mainboard 110, the third stopper 140 is located closer to the two sides of the assembled mainboard 110. The edge of the third stopper 140 is used as a reference. When the weighing mechanism mounting seat 400 is installed, the third stopper 140 is abutted against the weighing mechanism mounting seat 400, that is, the edge of the weighing mechanism mounting seat 400 is limited by the third stopper 140, so that the assembled mainboard 110 is positioned on the weighing mechanism mounting seat 400 through the third stopper 140.

In an optional embodiment, at least two second stops 130 are provided, and the length of the second stops 130 is determined according to the position of the core disk. After positioning, the assembly main board 110 is 344 mm away from the center of the core disk. One end of multiple second stops 130 is connected to the board surface of the assembly main board 110, and the other ends of multiple second stops 130 extend out of the edge of the assembly main board 110. For example, if the second stop 130 adopts a strip structure, one end of the second stop 130 is welded to the second board surface of the assembly main board 110, and the other end of the second stop 130 can contact and abut against the outer edge of the core disk. The length or position setting of the multiple second stops 130 can enable the multiple second stops 130 to abut against the core disk at the same time, such as two second stops 130 of equal length, and symmetrically arranged with the center beam when positioned.

In an optional embodiment, the assembly main board 110 is provided with a locking member 112. The locking member 112 is a bolt, a screw or other connecting parts. The assembly main board 110 is provided with an assembly hole 111 with a hole diameter of 13 mm. There are 4 assembly holes 111 in total, which are symmetrically arranged on the assembly main board 110. Other numbers can also be set. The assembly holes 111 can be through holes or threaded holes. The weighing mechanism mounting seat 400 is also provided with a docking hole. The position of the assembly hole 111 is exactly corresponding. The locking member 112 passes through the assembly hole 111 and the docking hole to fix the assembly main board 110 and the weighing mechanism mounting seat 400. In this way, the two plate-like structures of the weighing mechanism mounting seat 400 can be symmetrically arranged, and the interval between the two plate-like structures is 240 mm.
