Description

Technical Field

[0001] The utility model relates to the technical field of rail passenger vehicles, in particular to a side roof reinforcement rib pressing tool for a rail passenger vehicle roof. Background Art

[0002] As an essential component of the roof interior, the side roof is typically constructed of aluminum to reduce vehicle weight. To enhance its support strength, reinforcing ribs are affixed to the inside of the side roof. Currently, the side roof reinforcement ribs are clamped directly using metal clamps. During assembly, the metal clamps act directly on the ribs. While this clamping method is effective for horizontal surfaces, it falls far short of the required rib clamping for unusually shaped, steeply sloped side roofs. Insufficient friction often causes the clamps to slide down. Even if they do, the force dissipation reduces the frontal clamping force to a level below ideal, slowing workshop production efficiency and severely impacting product quality. For example, the side roofs of the Los Angeles subway project used a method for clamping the side roof reinforcements: the metal clamps were positioned and bonded onto the ribs, then pressed directly against them. This method was unable to adapt to the sloped contours of the side roof, resulting in poor clamping and a lack of a complete fit between the ribs and the side roof, impacting product quality. Utility Model Content

[0003] In view of the above problems, the purpose of the present invention is to provide a side roof reinforcement rib pressing tool for a railway passenger car roof, which is used to improve the pressing strength of the side roof reinforcement ribs to overcome the above-mentioned deficiencies in the prior art.

[0004] The utility model provides a side roof reinforcement rib pressing tool for a railway passenger car roof, comprising: an aluminum profile base frame, a conformal support block fixedly connected to the upper end surface of the aluminum profile base frame for supporting the side roof, a side roof placed on the conformal support block, reinforcement ribs bonded to the back surface of the side roof along the length direction of the side roof, two support assemblies fixedly connected to the aluminum profile base frame and located on both sides of the side roof, a support steel pipe located above the side roof, and a pressing assembly slidably connected to the support steel pipe;

[0005] The support assembly includes: a U-shaped support block, a T-bolt and a flange nut. The tail connection end of the U-shaped support block is fixed to the aluminum profile chassis by the T-bolt and the flange nut. The two ends of the support steel pipe are embedded in the U-shaped groove of the U-shaped support block so that the support steel pipe is above the side top.

[0006] The clamping assembly includes: a steel pipe slider, a clamping bolt and a welding nut. The sliding seat of the steel pipe slider is mounted on the supporting steel pipe and slides on the supporting steel pipe. The welding nut is welded to the steel pipe slider. The clamping bolt is threadedly connected in the welding nut. The clamping bolt is used to tighten the reinforcing rib on the side top. The steel pipe slider is moved on the supporting steel pipe so that the clamping bolt is above the reinforcing rib to be clamped. The clamping bolt in the welding nut is selected and tightened so that the top holding end of the clamping bolt presses the reinforcing rib on the side top.

[0007] As a preferred embodiment of the present invention, the steel pipe slider includes: a sliding seat with a square hole, a support seat fixedly connected to the sliding seat, the welding nut is welded to the support seat, and an avoidance hole is opened in the support seat corresponding to the position of the welding nut threaded hole, and the clamping bolt passes through the avoidance hole and is threadedly connected to the welding nut.

[0008] As a preferred embodiment of the present invention, the supporting steel pipe is a square pipe, and the sliding seat is sleeved on the supporting steel pipe through a square hole.

[0009] As a preferred embodiment of the present invention, both ends of the supporting steel pipe are fixedly connected with limit baffles, and the limit baffles are used to prevent the supporting steel pipe from sliding out of the U-shaped groove.

[0010] The beneficial effects of the utility model are as follows:

[0011] 1. The positioning method of the utility model is to tighten the bolts and nuts while satisfying the side top reinforcement ribs at any position on the side top, which greatly reduces the uncertainty of tightening when manually using metal pressing blocks, ensures the compression strength of the reinforcement ribs, improves the efficiency of workers' assembly operations, and improves the quality of products.

[0012] 2. The utility model quickly clamps the supporting steel pipe by installing supporting components on both sides of the aluminum profile chassis, thereby ensuring the efficiency of tooling use.

[0013] 3. The clamping assembly of the present invention is slidably connected to the supporting steel pipe, so that it can cope with clamping and fixing at different positions. The clamping assembly is clamped by selectively tightening bolts, so that different clamping forces can be adjusted. BRIEF DESCRIPTION OF THE DRAWINGS

The clamping bolt 702 is used to tighten the reinforcement rib 4 on the side top 3. By moving the steel pipe slider 701 on the supporting steel pipe 6, the clamping bolt 702 is located above the reinforcement rib 4 to be clamped. The clamping bolt 702 in the welding nut 703 is selected and tightened so that the top holding end of the clamping bolt 702 presses the reinforcement rib 4 on the side top 3. The steel pipe slider 701 comprises a sliding seat 704 with a square hole, a support seat 705 fixedly connected to the sliding seat 704, and a weld nut 703 welded to the support seat 705.
