AI Technical Summary
In the existing technology, the different fit between the wear plate of the slide groove and the slide groove of the side frame leads to difficulties in disassembly and assembly, and makes it difficult to remove and install without air source and power supply, which affects the safe operation and maintenance efficiency of railway vehicles.
A fixture for disassembling and assembling wear plates of railway freight car bogie slide grooves was designed. It adopts a combination structure of limit blocks, trapezoidal lead screws, guide rods and limit cylinders. By adjusting the spacing of the limit blocks and the position of the clamping blocks, the stable disassembly and assembly of the slide groove wear plates can be achieved.
It improves the disassembly and assembly efficiency of the chute wear plate, reduces the labor intensity of operators, enhances the safety and efficiency of on-site operations, and avoids misalignment and excessive compression.

Abstract
Claims
1. A railway truck bolster wear plate removal and assembly fixture comprising a railway truck bolster wear plate (1) characterised in that: A trapezoidal screw (3) is installed between two symmetrically arranged limit blocks (2). The inner side of the limit block (2) on the left side is provided with an internal thread. One end of the trapezoidal screw (3) with a stop is threadedly connected to the limit block (2) on the left side. The inner side of the limit block (2) on the right side is provided with a through hole. The other end of the trapezoidal screw (3) is movably connected to the limit block (2) on the right side through the through hole. A clamping block (4) is provided on the upper part of both limit blocks (2). A baffle (5) is installed on the outer side of both limit blocks (2). A guide rod (6) is installed on the inner side of the baffle (5) on the left side. A limit cylinder (7) is installed on the inner side of the baffle (5) on the right side. The limit cylinder (7) and the guide rod (6) correspond one-to-one. The other end of the trapezoidal screw (3) passes through the baffle (5) on the right side and is tightened by a nut (8).
2. The tool as set forth in claim 1, wherein: The inner sides of both the left and right limiting blocks (2) are provided with inclined surfaces that slope inward from top to bottom.
3. The tool as set forth in claim 1, wherein: The inner diameter of the limiting cylinder (7) is the same as the outer diameter of the guide rod (6), and the depth of the limiting cylinder (7) is less than the length of the guide rod (6).
4. The railway truck sliding bolster wear plate removal and assembly fixture of claim 1 wherein: A handle (9) is installed at the lower end of the limit block (2) located on the left side.
