Description

Technical Field

[0001] The invention belongs to the technical field of rail vehicles, and in particular relates to a tool for positioning front and rear cluster plate seats of a traction beam of a rail vehicle and a use method thereof. Background Art

[0002] The traction beam structure corresponding to the 13B and 15 No. couplers commonly used in rail vehicles has front and rear cluster plate seats. The positioning dimensions and form and position tolerances of the front and rear cluster plate seats have a direct impact on the installation of the couplers in the later stage. According to the drawings, the opening size of the front and rear cluster plate seats is 625 0 -3 In order to solve the gap problem between the front and rear cluster plate seats and the coupler cluster plate seats, according to the dimension chain calculation, the process personnel required the opening size of the front and rear cluster plate seats to be 623 0 -1 The existing method for positioning and installing the front and rear panel mounts involves: marking the front panel mount for alignment - marking the rear panel mount for alignment - measuring the gap between the two panels - measuring the diagonal difference between the two panels - fine-tuning the positioning of the two panels - and finally securing the two panels. This process is inefficient and cannot quickly achieve positioning of the front and rear panels, resulting in low efficiency. Furthermore, the positioning accuracy of the two panels cannot be guaranteed using this method, reducing work quality. Therefore, improvements are necessary. Summary of the Invention

[0003] The technical problem solved by the present invention is: to provide a tool for positioning the front and rear cluster plate seats of a rail vehicle traction beam and a method for using the tool. The present invention designs the positioning tool based on the installation problem of the front and rear cluster plate seats of the traction beam on site, improves the assembly efficiency of the front and rear cluster plate seats, facilitates the removal of the tool, and utilizes the precision of the tool to ensure the size and parallelism of the front and rear cluster plate seats, thereby ensuring the quality of the operation.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is:

[0005] The left end face of the adjusting plate is beyond the left end face of the limiting plate, and the distance between the left end face of the adjusting plate and the right end face of the fixed positioning plate in the positioning state is the positioning size between the front cluster plate seat and the rear cluster plate seat on the traction beam of the rail vehicle.

[0006] As a further limitation of the above solution, the intermediate support rod is made of a round tube.

[0007] To further limit the above solution, there are two or more push rods symmetrically distributed, the push rods are made of tightening screws, and threaded holes that are screwed into the tightening screws are formed at corresponding positions of the auxiliary support plate.

[0008] As a further limitation of the above solution, the adjustment positioning plate is a U-shaped plate structure composed of a positioning base plate and positioning blocks on both sides, and the positioning blocks on both sides are symmetrically arranged on both sides of the outer side of the positioning base plate.

[0009] The method for using the tooling for positioning the front and rear cluster plate seats of the rail vehicle traction beam specifically includes the following steps:

[0010] When the tooling is used to position the front and rear cluster plate seats: the outer side surfaces of the fixed positioning plate and the adjustable positioning plate are both machined surfaces, the push rod is tightened to put the adjustable positioning plate in a positioning state, and the opening size of the two machined surfaces is the positioning size between the front cluster plate seat and the rear cluster plate seat on the traction beam of the rail vehicle; when assembling the front and rear cluster plate seats, first mark and position the front cluster plate seat, and then use the tooling to position the rear cluster plate seat in combination with the positioning position of the front cluster plate seat, ensuring that the front and rear cluster plate seats are tightly attached to the two machined surfaces of the tooling, thereby ensuring the opening size and parallelism of the front and rear cluster plate seats, rechecking the opening size of the front and rear cluster plate seats, and finally spot-fixing the positioned front and rear cluster plate seats;

[0011] When removing the tooling: When the tooling is difficult to remove, loosen the ejector rod to move the adjustment positioning plate backward, reduce the gap size between the adjustment positioning plate and the fixed positioning plate, and the tooling can be removed quickly and effortlessly.

[0012] The advantages of the present invention compared with the prior art are:

[0013] 1. This solution optimizes the dimensional tolerance requirements for the front and rear cluster plate seats of the rail vehicle traction beam based on on-site issues and designs a positioning tool. This tool can quickly position the front and rear cluster plate seats during installation, improving the assembly efficiency of the front and rear cluster plates by more than 30%.

[0014] 2. In this solution, one of the positioning plates in the front and rear cluster plate seat positioning fixture is designed to be axially movable. When used for positioning, the push rod is used to tighten the two positioning plates to ensure that the distance between the outer machined surfaces can meet the positioning requirements of the front and rear cluster plate seats. When the fixture needs to be removed, the push rod is released to reduce the distance between the two positioning plates, thereby facilitating quick and labor-saving removal of the fixture. The structure is simple and very convenient to use.

[0015] 3. This solution can use the precision of the tooling to ensure the size and parallelism of the front and rear cluster plate seats. It is more effective than workers relying on experience, using tape measures, and rulers to ensure this. It enables higher size requirements to be achieved, not only improving the work efficiency on the workshop site, but also ensuring the work quality. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-3 , details the embodiments of the present invention.

[0021] Example: Tooling for positioning the front and rear cluster plate seats of railcar traction beams, see Figure 1-3 When the cam 2 is in the closed position, the cam 2 is in the closed position, and the cam 2 is in the closed position, so that the cam 2 can move freely, and the cam 2 can move freely, and the cam 2 can move freely, and the cam 2 can move freely, and the cam 2 can move freely.

[0022] In one embodiment, the intermediate support rod 1 is made of a round tube, which is easy to obtain and manufacture.

[0023] In one embodiment, see Figure 1As shown, there are two or more push rods 6 symmetrically distributed, and the push rods 6 are made of tightening screws. The corresponding positions of the auxiliary support plate 5 are provided with threaded holes 5-1 that are screwed with the tightening screws. By screwing in the tightening screws, the adjustment positioning plate can be tightened or loosened, and the operation is simple and convenient.

[0024] In one embodiment, see Figure 1 As shown, the adjustment positioning plate 4 is a U-shaped plate structure composed of a positioning base plate 4-1 and positioning blocks 4-2 on both sides. The positioning blocks 4-2 on both sides are symmetrically arranged on both sides of the outer side of the positioning base plate 4-1, which can avoid interference with the middle limit plate 3.

[0025] A method for using a tool for positioning front and rear cluster plate seats of a rail vehicle traction beam, specifically comprising the following steps:

[0026] When the tool is used to position the front and rear cluster plate seats: the fixed positioning plate 2 and the adjustable positioning plate 4 are both machined surfaces, and the push rod 6 is pressed to make the adjustable positioning plate 4 in the positioning state. The opening size of the two machined surfaces is the installation positioning size between the front cluster plate seat and the rear cluster plate seat on the traction beam of the rail vehicle, which is 622. +0.6 +0.2 mm, with a parallelism of 0.5 mm. When assembling the front and rear panel seats, first mark and locate the front panel seat. Then, use this tooling in conjunction with the front panel seat's positioning to position the rear panel seat, ensuring that the front and rear panel seats are in close contact with the tooling's two machine-added surfaces. This ensures the front and rear panel seats' opening dimensions and parallelism. The opening dimensions of the front and rear panel seats are then reviewed, and finally, the positioned front and rear panel seats are spot-fastened. This tooling can quickly position the front and rear panel seats during installation, improving the efficiency of front and rear panel assembly by over 30%.

[0027] In addition, the precision of the tooling can be used to ensure the size and parallelism of the front and rear cluster plate seats, which is more effective than workers relying on experience, using tape measures, and rulers to ensure guarantees. It enables higher dimensional requirements to be achieved, improves the efficiency of workshop operations, and ensures work quality.

[0028] When the tooling is taken out: When the tooling is difficult to take out, loosen the push rod 6 to move the adjustment positioning plate 4 backward, and the opening size between the adjustment positioning plate 4 and the fixed positioning plate 2 is reduced, and the tooling can be taken out. The structure is simple and very convenient to use.
