Description

Technical Field

[0001] This application relates to the field of coupler seat inspection, and in particular to a tooling for re-inspecting the hole positions of coupler seats. Background Technology

[0002] The coupler seat is a component of the railway freight car coupler, used to install the coupler and provide connection and support to ensure the safe and stable operation of railway freight cars. After production, the coupler seat needs to be inspected. Following inspection, the set of mounting holes in the vertical direction of the coupler seat must be re-inspected to ensure that the mounting holes meet assembly requirements.

[0003] In related technologies, workers use a ruler to measure a set of mounting holes in the vertical direction of the coupler seat to determine whether the mounting holes are offset. However, for couplers with multiple sets of mounting holes, multiple measurements are required, resulting in low re-inspection efficiency. Therefore, improvements are needed. Utility Model Content

[0004] To improve the efficiency of re-inspection of coupler seats, this application provides a tooling for re-inspecting the hole positions of coupler seats.

[0005] The technical solution of the hole position re-inspection fixture for coupler seats provided in this application is as follows:

[0006] A tooling for re-inspecting holes in a coupler seat includes a base plate, a bracket, and a re-inspection plate. The bracket is located on the upper side of the base plate. The re-inspection plate is located on the bracket and is perpendicular to the base plate. The re-inspection plate has a plurality of first inspection holes spaced apart along its own length direction and a plurality of second inspection holes spaced apart along its own length direction. The first inspection holes and the second inspection holes are spaced apart along the width direction of the re-inspection plate.

[0007] By adopting the above technical solution, in practical applications, the staff places the coupler seat on the base plate and then attaches the coupler seat to the inspection plate, so that the mounting holes on the coupler seat correspond to the first inspection hole and the second inspection hole, so as to realize the inspection of one set of mounting holes. Since there are multiple first inspection holes and second inspection holes, multiple sets of mounting holes can be inspected at the same time, thereby effectively improving the inspection efficiency of the coupler seat.

[0008] Preferably, the re-inspection plate is detachably connected to the bracket.

[0009] By adopting the above technical solution, and by setting the re-inspection plate to be detachably connected to the bracket, it is possible to replace the re-inspection plates with first and second inspection holes of different sizes, positions, and quantities, so as to be suitable for coupler seats of different sizes and shapes, thereby improving the applicability of the hole re-inspection tooling.

[0010] Preferably, the hole re-inspection fixture further includes multiple connecting bolts, one end of each connecting bolt passing through the re-inspection plate and threadedly connected to the bracket, and the other end abutting against the re-inspection plate and located in the re-inspection plate.

[0011] By adopting the above technical solution and setting multiple connecting bolts, a detachable connection between the inspection plate and the bracket can be achieved, which is simple in structure and easy to operate.

[0012] Preferably, the re-inspection plate includes a first plate and a second plate, the first plate and the second plate are arranged at a distance along the vertical direction, the first plate and the second plate can slide along the vertical direction on the bracket, and the first detection hole is located on the first plate and the second detection hole is located on the second plate.

[0013] By adopting the above technical solution, and by setting a first plate and a second plate, the first plate and the second plate can slide on the bracket, and the distance between the first detection hole and the second detection hole can be adjusted to suit different coupler seats, thereby improving the applicability of the hole position re-inspection tooling.

[0014] Preferably, the hole re-inspection fixture further includes a bidirectional screw, which has a first thread and a second thread. The first thread and the second thread are arranged in opposite directions. The bidirectional screw is rotatably connected to the bracket, and the first plate is threadedly connected to the first thread, and the second plate is threadedly connected to the second thread.

[0015] By adopting the above technical solution, by setting a bidirectional screw, the first plate and the second plate are brought closer or further apart by rotating the bidirectional screw, so as to adjust the distance between the first plate and the second plate, that is, to adjust the distance between the first detection hole and the second detection hole.

[0016] Preferably, the hole re-inspection fixture further includes a limiting block, which is disposed on the bracket and used to abut against the second plate to prevent the second plate from detaching from the bracket.

[0017] By adopting the above technical solution and setting a limit block, the second plate can be prevented from detaching from the bracket as much as possible, so as to ensure the stability of the hole position re-inspection fixture.

[0018] Preferably, one end of the limiting block is rotatably connected to the bracket.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.

[0032] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0033] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0034] This application discloses a tooling for re-inspecting the hole positions of a car coupler seat.

[0035] Example 1:

[0036] Reference Figure 1 The hole position re-inspection fixture includes a base plate 1, a bracket 2, and an inspection plate 3. The base plate 1 is rectangular and horizontally positioned. The bracket 2 is fixedly connected to the upper side of the base plate 1 by welding. The inspection plate 3 is fixedly connected to one side of the bracket 2. The inspection plate 3 is also rectangular and is perpendicular to the base plate 1.

[0037] The re-inspection plate 3 has multiple first inspection holes 31 spaced apart along its length, and multiple second inspection holes 32 spaced apart along its length. The number of second inspection holes 32 is the same as the number of first inspection holes 31. The first inspection holes 31 and the second inspection holes 32 are spaced apart along the width of the re-inspection plate 3, that is, the first inspection holes 31 and the second inspection holes 32 are spaced apart vertically. It should be noted that both the first inspection holes 31 and the second inspection holes 32 are strip-shaped holes to meet different re-inspection requirements.

[0038] It should be noted that the coupler seat has two sets of mounting holes, which are spaced apart along the length of the inspection plate 3. Each set of mounting holes has two holes in the vertical direction, which match the first inspection hole 31 and the second inspection hole 32.

[0039] In practical applications, the staff places the coupler seat horizontally on the base plate 1, and then attaches the coupler seat to the inspection plate 3. By moving the coupler seat, the mounting holes on the coupler seat are aligned with the first inspection hole 31 and the second inspection hole 32. If the mounting holes are aligned with the first inspection hole 31 and the second inspection hole 32 and there is no lateral offset, it is considered qualified, so as to realize the re-inspection of one set of mounting holes. Since there are multiple first inspection holes 31 and second inspection holes 32, the re-inspection of two sets of mounting holes can be realized at the same time, thereby effectively improving the re-inspection efficiency of the coupler seat.

[0040] In some embodiments, the re-inspection plate 3 is detachably connected to the bracket 2, so that the re-inspection plate 3 can be replaced. By replacing it with different re-inspection plates 3 (e.g., different sizes, positions, and numbers of the first inspection hole 31 and the second inspection hole 32), it can be adapted to coupler seats of different sizes and shapes, thereby improving the applicability of the hole re-inspection tooling.

[0041] Reference Figure 2 In some embodiments, the hole position re-inspection fixture also includes multiple connecting bolts 4. One end of each connecting bolt 4 passes through the inspection plate 3 and is threaded to the bracket 2, while the other end abuts against the inspection plate 3, thereby achieving a detachable connection between the inspection plate 3 and the bracket 2. The structure is simple and easy to operate, facilitating the installation and removal of the inspection plate 3. Specifically, the end of the connecting bolt 4 abutting against the inspection plate 3 is located in the clearance hole of the inspection plate 3 to prevent the connecting bolt 4 from protruding from the inspection plate 3, thus ensuring that the coupler seat can fit snugly against the inspection plate 3.

[0042] The implementation principle of this embodiment is as follows: In practical application, the operator places the coupler seat horizontally on the base plate 1, and then attaches the coupler seat to the inspection plate 3. By moving the coupler seat, the mounting holes on the coupler seat are aligned with the first inspection hole 31 and the second inspection hole 32. If the mounting holes are aligned with the first inspection hole 31 and the second inspection hole 32 and there is no lateral offset, it is considered qualified, so as to realize the re-inspection of one set of mounting holes. Since there are multiple first inspection holes 31 and second inspection holes 32, the re-inspection of two sets of mounting holes can be realized at the same time, thereby effectively improving the re-inspection efficiency of the coupler seat.

[0043] Example 2:

[0044] Reference Figure 3This embodiment is identical to Embodiment 1 in all other structural aspects, except that the re-inspection plate 3 includes a first plate 33 and a second plate 34. The first plate 33 and the second plate 34 are spaced apart vertically, with the first plate 33 positioned above the second plate 34. The first plate 33 and the second plate 34 slide on the bracket 2 in a vertical direction. Each first detection hole 31 is located on the first plate 33, and each second detection hole 32 is located on the second plate 34. By sliding the first plate 33 and the second plate 34, the distance between the first detection holes 31 and the second detection holes 32 can be adjusted to accommodate different coupler seats, thereby improving the applicability of the hole re-inspection fixture.

[0045] In some embodiments, the hole re-inspection fixture further includes a bidirectional screw 5, which has a first thread and a second thread (not shown in the figure), with the first thread and the second thread having opposite directions. The bidirectional screw 5 is vertically rotatably connected to the bracket 2, and a first plate 33 is threadedly connected to the first thread, and a second plate 34 is threadedly connected to the second thread. By rotating the bidirectional screw 5, the first plate 33 and the second plate 34 are brought closer or further apart to adjust the distance between them, which in turn adjusts the distance between the first detection hole 31 and the second detection hole 32, thus facilitating its application to different coupler seats.

[0046] Reference Figure 3 and Figure 4 In some embodiments, the hole position re-inspection fixture also includes a limiting block 6, which is installed on the bracket 2 and used to abut against the second plate 34 to limit the second plate 34 from sliding down excessively, that is, to limit the second plate 34 from detaching from the bracket 2, so as to ensure the stability of the hole position re-inspection fixture.

[0047] In some embodiments, one end of the limiting block 6 is rotatably connected to the bracket 2. By rotating one end of the limiting block 6, the limiting block 6 releases its restriction on the second plate 34, so as to facilitate the installation and removal of the second plate 34.

[0048] In some embodiments, the hole position re-inspection fixture further includes a slide rail 7 and two sliders 8. The slide rail 7 is arranged vertically and fixedly connected to one side of the bracket 2. The two sliders 8 are respectively fixedly connected to the side of the first plate 33 and the second plate 34 near the bracket 2, and each slider 8 is slidably connected to the slide rail 7 to improve the stability of the sliding of the first plate 33 and the second plate 34.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
