Problems solved by technology

However, since there is currently no assembly welding tire specially designed for the upper tie rod with a certain angle of the tie rod head, the problem of affecting the quality of the brake assembly due to the angle of the tie rod head exceeding the designed tolerance range often occurs during the welding process of the upper tie rod. There are certain safety hazards in the pull rod during the operation of the vehicle

Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0016] Such as figure 2 As shown, the present invention includes a frame 1 , a chute 11 is arranged on the top of the frame 1 , and a pull rod support 2 for connecting the pull rod head 9 is slidably arranged on the chute 11 . A rotating bracket composition 3 is connected on the frame 1 at one end of the chute 11. The rotating bracket composition 3 includes a bracket 31 fastened to the frame 1, and a rotation bracket for connecting the pull rod head 8 is installed on the bracket 31. Pull rod seat 32. Wherein, the tie rod support 2 and the rotating tie rod seat 32 are at the same level.

[0017] In the above example, if image 3 As shown, the tie rod support 2 includes a channel steel 21 with an opening downwards, and a vertical plate 22 is set on the top surface of the channel steel 21 away from the end of the rotating bracket composition 3, and a...

Abstract

The invention provides an installing and welding fixture device for an upper link of a wagon. The device comprises a rack. A sliding groove is formed in the top of the rack. A pull rod support used for being connected with a first pull rod head is arranged on the sliding groove in a sliding manner. The part, at one end of the sliding groove, of the rack is connected with a rotating support assembly. The rotating support assembly comprises a support fixedly connected to the rack. The support is rotationally provided with a rotating pull rod base used for being connected with a second pull rod head. The pull rod support and the rotating pull rod base are located at the same horizontal height. As the pull rod support is arranged at the upper portion of one end of the rack in the sliding manner and the rotating support assembly is arranged at the upper portion of the other end of the rack, components of the upper pull rod can be placed on the device to be fixed and welded at a time, and the work error generated during welding is prevented. As the sliding groove is formed in the upper portion of the rack, and the pull rod support is arranged on the sliding groove in the sliding manner, welding of the upper pull rod with different length requirements can be met by adjusting the position of the pull rod support.

Description

technical field [0001] The invention relates to a tire welding device, in particular to a tire welding device for an upper tie rod group of a railway freight car. Background technique [0002] Railway wagon vehicles are all provided with pull-up rods on the brake accessories, and the pull-up rod is an important part for connecting the brake lever and the swimming lever. Such as figure 1 As shown, in order to meet the use requirements of different vehicles, the tie rod head 8 at one end of the upper tie rod is usually arranged by rotating a certain angle relative to the tie rod head 9 at the other end. However, since there is currently no assembly welding tire specially designed for the upper tie rod with a certain angle of the tie rod head, the problem of affecting the quality of the brake assembly due to the angle of the tie rod head exceeding the designed tolerance range often occurs during the welding process of the upper tie rod. There are certain safety hazards in the...
