Description

Technical Field

[0001] This utility model belongs to the field of welding tooling technology, and more specifically, relates to a welding tooling for a cylinder pipe seat. Background Technology

[0002] When manually welding the air cylinder pipe seat, it is difficult for the welder to maintain absolute perpendicularity between the pipe seat and the air cylinder axis throughout the welding process. Tilting of the pipe seat can lead to tilted installation of the subsequent valve, causing installation difficulties, poor sealing, or stress concentration. Poor sealing can result in continuous leakage of compressed air within the air cylinder, leading to a drop in brake cylinder pressure, abnormal train pipe pressure, and ultimately weakened train braking force or brake system failure. A misaligned valve may not be able to open or close completely, preventing the complete drainage of water within the air cylinder, which can easily corrode over time. Utility Model Content

[0003] The purpose of this invention is to provide a welding fixture for a cylinder pipe seat, overcoming the aforementioned defects in the prior art.

[0004] The technical solution to achieve the purpose of this utility model is: a welding fixture for a steel pipe seat, comprising: a support frame and a cylinder support frame, characterized in that: a pipe seat fixing plate and two cylinder support frames are provided on the support frame; the pipe seat fixing plate has a through hole and is provided with a clamping bolt and a clamping washer, the clamping washer is sleeved below the clamping bolt, and the bottom of the clamping bolt passes through the through hole on the clamping washer and connects with the through hole of the pipe seat fixing plate; the cylinder support frame has a groove, and the clamping bolt and the clamping washer cooperate with the pipe seat fixing plate to press the cylinder body into the groove.

[0005] In a preferred embodiment, the tube seat fixing plate is located between two air cylinder support frames and is fixed to the support frame by screws. The bottom of the clamping bolt passes through the clamping washer and is connected by the thread in the through hole on the tube seat fixing plate or by the nut fixed below the through hole.

[0006] In a preferred embodiment, the air cylinder support frame is fixed to the support frame with screws, and its groove is set to be arc-shaped or square.

[0007] In a preferred embodiment, the clamping shim is configured as a straight shim. After the clamping bolt and the clamping shim clamp the air cylinder body, the straight bar of the clamping shim is parallel to the normal line of the air cylinder body.

[0008] Compared with the prior art, the technical effects that this utility model can achieve are:

[0009] This utility model uses a pipe seat fixing plate, a clamping bolt, and a clamping washer. After the clamping bolt is threadedly connected to the through hole of the pipe seat fixing plate, the clamping washer, together with the clamping washer, firmly presses the air cylinder body onto the air cylinder support frame, so that the air cylinder body will not move, thereby positioning the air cylinder pipe seat, making the welding position and angle more precise and convenient.

[0010] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0013] Explanation of reference numerals in the attached figures:

[0014] 1—Support frame, 2—Cylinder support frame, 3—Pressure bolt, 4—Pressure gasket, 5—Pipe seat fixing plate, 6—Cylinder body, 7—Cylinder pipe seat. Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] Example 1:

[0017] like Figure 1 , 2As shown, a welding fixture for a cylinder pipe seat includes a support frame 1, a cylinder support bracket 2, and a pipe seat fixing plate 5. Two cylinder support brackets 2 are screwed onto the support frame 1 and installed in parallel. Each cylinder support bracket has an arc-shaped groove that matches the curve of the outer surface of the cylinder body 6, thereby limiting the movement of the cylinder body 6 and preventing axial runout. A cylinder pipe seat hole is provided on the side wall of the cylinder body 6 for installing a cylinder pipe seat 7. A pipe seat fixing plate 5 is mounted on the support frame 1 with screws, located between the two air cylinder support frames 2. The pipe seat fixing plate 5 has a through hole located at its center. A nut is fixed below the pipe seat fixing plate 5, with the nut hole aligned with the through hole. The pipe seat fixing plate 5 is equipped with a clamping bolt 3 and a clamping washer 4. The clamping washer 4 is tightly fitted onto the bottom of the clamping bolt 3. The top of the clamping bolt 3 is designed in a straight line to increase the rotational lever arm and save effort during rotation. Horizontal bars are provided on both sides of the through hole of the clamping washer 4, forming a horizontal straight line. Rotate the clamping bolt 3 and clamping washer 4 through the through hole of the air cylinder tube seat 7 and the tube seat fixing plate 5 and connect them to the nut hole below the fixing plate. This clamps the air cylinder body 6 into the groove of the air cylinder support frame and clamps the air cylinder tube seat 7 onto the side wall of the air cylinder body 6. After clamping, the straight bar of the clamping washer 4 is parallel to the normal line of the air cylinder body 6. Then, weld the air cylinder tube seat 7. After welding, rotate the clamping bolt 3 in the opposite direction, remove the clamping bolt 3 and clamping washer 4, and then replace the air cylinder body 6.

[0018] Example 2:

[0019] As another implementation of this embodiment 1, the groove of the cylinder support frame 2 is set to be square, and the width and height of the groove are adapted to the diameter of the air cylinder body 6, and the air cylinder body 6 is embedded in the groove.

[0020] Example 3:

[0021] As another implementation of this embodiment, the through hole in the pipe seat fixing plate 5 can be threaded to replace the nut fixed below, and the diameter of the through hole matches the stud of the clamping bolt 3. After the clamping bolt 3 is rotated, it connects with the thread of the through hole in the pipe seat fixing plate 5, thereby causing the clamping washer 4 to clamp the air cylinder body 6 and the air cylinder pipe seat 7.

[0022] The technical means disclosed in this utility model are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features.
