Description

Technical Field

[0001] The utility model relates to the technical field of train muffler production, in particular to a train muffler connecting component positioning tool. Background Art

[0002] The train muffler is a device installed in the exhaust system of the train, which is mainly used to reduce or eliminate the noise generated by the train during its travel. In order to ensure the effect of silencer, the size of the train muffler is usually relatively large. In order to facilitate its installation in the train exhaust system, multiple connecting components are set on both sides to ensure that the train muffler can be well fixed to the exhaust system. In the prior art, the connecting components are generally directly welded on both sides of the train muffler, but when the workers perform the welding operation, they manually straighten the connecting components, which may cause the connecting components to be skewed after welding, and the spacing between two adjacent connecting components may also have a large error, which causes the train muffler to be unable to be smoothly installed in the train exhaust system. Utility Model Content

[0003] In view of the deficiencies of the above-mentioned related prior arts, the present application provides a train muffler connecting component positioning tool, which can carry out load-bearing positioning of the connecting component, reduce errors occurring during the welding process, and has strong practicality.

[0007] Furthermore, support rods are provided at the four corners of the U-shaped seat, the lifting frame is sleeved on the support rods and connected to the moving end of the vertical lifting mechanism, and the vertical lifting mechanism is installed on the U-shaped seat.

[0008] Furthermore, limiting grooves are provided on both sides of the lifting frame in the width direction, and the length direction of the limiting grooves is parallel to the width direction of the lifting frame.

A first spring is also sleeved on the cross bar, and the two ends of the first spring respectively abut against the retaining ring and the moving block and are always in a compressed state.

[0010] Furthermore, two movable plates are provided above the lifting frame, which are respectively arranged on both sides of the lifting frame in the width direction. The movable plate is located between the supporting block and the movable block, and a penetrating slide groove is provided on the side along the length direction. The cross bar passes through the slide groove. Both ends of the movable plate are connected to the movable end of the horizontal linear mechanism, and the horizontal linear mechanism is installed on the lifting frame.

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0020] like Figure 1-Figure 3 As shown, this example provides a train muffler connection component positioning tool, including: a U-shaped seat 100 and a bearing assembly 200.

[0021] The bearing assembly 200 is arranged above the U-shaped seat 100, and includes a lifting frame 201 that moves in the vertical direction. A plurality of movable blocks 202 with adjustable spacing are arranged on both sides of the width direction of the lifting frame 201. The movable blocks 202 are provided with support blocks 203 that move along the length direction of the lifting frame 201 and are used to bear the connecting components. The support blocks 203 are provided with a limiting plate 204 that moves in the vertical direction and is used to limit the connecting components.

[0022] Specifically, support rods 101 are provided at the four corners of the U-shaped seat 100, and the lifting frame 201 is sleeved on the support rods 101 and connected to the moving end of the vertical lifting mechanism. The vertical lifting mechanism is installed on the U-shaped seat 100. After the train muffler is transferred to the U-shaped seat 100, the lifting frame 201 can be driven down by the vertical lifting mechanism to facilitate subsequent welding operations.

[0023] Specifically, limiting grooves 205 are provided on both sides of the lifting frame 201 in the width direction, and the length direction of the limiting grooves 205 is parallel to the width direction of the lifting frame 201. The moving block 202 slides in the limiting grooves 205, so as to facilitate the adjustment of the distance between the two connected support blocks 203 to meet different needs, and is locked with screws to prevent the moving block 202 from sliding during welding.

[0024] Specifically, the moving block 202 is provided with a horizontally arranged cross bar 206 with its axis parallel to the length direction of the lifting frame 201, the support block 203 is installed at one end of the cross bar 206, and a retaining ring 207 is provided at the other end of the cross bar 206. The cross bar 206 is also provided with a first spring 208, and the two ends of the first spring 208 are respectively abutted against the retaining ring 207 and the moving block 202, and are always in a compressed state. When performing welding operations, the support block 203 is moved toward the center of the lifting frame 201 so that the connecting component abuts against the side of the train muffler. At this time, the first spring 208 is further compressed, so that after the welding is completed, the support block 203 can automatically reset under the action of the first spring 208.

[0025] Specifically, two movable plates 209 are provided above the lifting frame 201, which are respectively arranged on both sides of the lifting frame 201 in the width direction. The movable plate 209 is located between the support block 203 and the movable block 202, and a penetrating slide groove 210 is provided on the side along the length direction. The cross bar 206 passes through the slide groove 210. Both ends of the movable plate 209 are connected to the movable end of the horizontal linear mechanism. The horizontal linear mechanism is installed on the lifting frame 201. The two movable plates 209 can be driven to move toward the center of the lifting frame 201 through the horizontal linear mechanism. Under the push of the movable plate 209, the support block 203 moves toward the center of the lifting frame 201.

[0026] Specifically, the support block 203 is L-shaped, and baffles 211 are provided on both sides thereof for abutting against both sides of the connecting member to limit the positions of both sides of the connecting member.

[0027] Specifically, a side plate 212 is provided at the upper end of the support block 203, a support rod 213 is provided on the side plate 212, the limit plate 204 is sleeved on the support rod 213, a connecting plate 214 is also provided at the upper end of the support rod 213, a second spring 215 is sleeved on the support rod 213, two ends of the second spring 215 are respectively abutted against the connecting plate 214 and the limit plate 204, and are always in a compressed state. Under the action of the second spring 215, the limit plate 204 has a tendency to move downward, so that the connecting component can be pressed into the support block 203.

[0028] Specifically, because when the second spring 215 applies a force to the limit plate 204, the point of action is not located within the projection of the connecting member in the vertical direction, the limit plate 204 is arranged in a Z shape, and a pressure rod 216 is also provided on the top surface located in the projection area of ​​the support block 203 in the vertical direction. The upper end of the pressure rod 216 is passed through the connecting plate 214, and a third spring 217 is sleeved on the pressure rod 216. The two ends of the third spring 217 are respectively abutted against the connecting plate 214 and the limit plate 204, and are always in a compressed state. The third spring 217 further applies a downward force to the limit plate 204, and the point of action is located within the projection of the connecting member in the vertical direction, thereby ensuring a better limiting effect.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Obviously, those skilled in the art can make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
