Background Art

[0002] The gas guide device is an important component of the electric transmission system for new diesel locomotives. It is used to guide the air flow in the engine and promote the internal combustion efficiency of the engine. The gas guide device includes an inner cylinder and an outer cylinder, and the inner and outer cylinders are connected by a guide vane.

[0029] Furthermore, the second clamping mechanism 5 comprises a second supporting arm, and a second clamping device 51 is provided at one end of the second supporting arm.

[0030] Furthermore, the third clamping mechanism 6 comprises a third supporting arm, one end of which is provided with a third clamping device 61 , and the bottom of the third clamping device 61 is provided with an extended clamping block 62 .

[0031] Furthermore, a wedge-shaped platform 71 for supporting the guide vane is provided on the upper side of the support seat 7 .

[0032] Furthermore, the first clamping device 41 includes a first screw hole, which is arranged at the upper end of the first support arm 42, and the first clamping screw passes through the first screw hole. The upper end of the first clamping screw is provided with a first handle, and the lower end of the first clamping screw is provided with a first clamping plate.

[0033] Furthermore, the second clamping device 51 includes a second screw hole, which is arranged at the upper end of the second support arm, and the second clamping screw passes through the second screw hole. The upper end of the second clamping screw is provided with a second handle, and the lower end of the second clamping screw is provided with a second clamping plate.

[0034] Furthermore, the third clamping device 61 includes a third screw hole, the third screw hole is arranged at the upper end of the third support arm, the third clamping screw passes through the third screw hole, the upper end of the third clamping screw is provided with a third handle, the lower end of the third clamping screw is provided with a third clamping plate, the extended clamping block 62 is arranged on the lower side of the third clamping plate, and a rotary pair is arranged between the extended clamping block 62 and the lower end of the third clamping screw and an axial limiting structure is provided.

[0035] Specifically, the first clamping device 41, the second clamping device 51, and the third clamping device 61 adopt the clamping device in the prior art. The clamping device can be a C-shaped clamp structure in the prior art, or a rod channel. A clamping rod is arranged in the rod channel. The clamping rod and the rod channel form a threaded rotation pair. A handle is arranged at the upper end of the clamping rod, and a clamping sheet is arranged at the lower end of the clamping rod. The clamping rod is rotated by controlling the handle, and the clamping rod pushes the clamping sheet to contact the gas guide device 20 to form a tightening effect. Among them, the first clamping device 41 is used to clamp the inner cylinder 201, the second clamping device 51 is used to clamp the outer cylinder upper ring 203, and the third clamping device 61 is used to clamp the outer cylinder lower ring 204. Since the outer cylinder upper ring 203 exists above the outer cylinder lower ring 204, the third clamping device 61 cannot be directly clamped. An extended clamping block 62 is arranged at the bottom of the third clamping device 61 to clamp the outer cylinder lower ring 204.

[0036] Specifically, the wedge-shaped platform 71 is used to match the angle size of the guide plate 202 , and the guide plate 202 can be assembled by placing it on the wedge-shaped platform 71 at an angle.

[0037] Specifically, the base 1 is made of No. 10 channel steel for welding to ensure that the tooling has sufficient rigidity to support the product. The upper part is welded with a workbench 2, which is laser cut from an 8mm steel plate. There are laser engraved lines on the surface of the workbench 2, which are the assembly lines of the positioning seats and clamping seats of the tooling.

[0038] The truncated table 3 and the support seat 7 are both made of 5 mm steel plates cut by laser and then welded. When assembling the truncated table 3 and the support seat 7, they can be welded after being aligned with the laser engraved lines on the workbench 2.

[0039] The same parts of the first clamping mechanism 4, the second clamping mechanism 5, and the third clamping mechanism 6 are composed of laser-cut 5mm steel plates, clamping screws and pins. When in use, the front end of the support arm can be flipped 90° by inserting and pulling out the pin, which is convenient for demoulding the gas diversion device after assembly welding. The different parts are that the third clamping mechanism 61 has an extended clamping block 62 composed of laser-cut 16mm steel plates. When in use, the lower ring 204 of the outer cylinder is clamped by the extended clamping block 62, and the second clamping mechanism 51 directly uses the clamping screw to clamp the upper ring 203 of the outer cylinder. The first clamping mechanism 4 is welded with a laser-cut 5mm steel plate and a clamping screw. It is a portable hand-held clamp, which is flexible and easy to use for disassembly and clamping.

[0040] The working process of this embodiment:

[0041] Step 1: Place the inner cylinder 201 on the truncated table 3, align the inner cylinder 201 with the outer circle of the truncated table 3, and clamp the inner cylinder 201 and the truncated table 3 with the first clamping mechanism 4;

[0042] Step 2: Place the outer cylinder lower ring 204 on the workbench 2, align the outer ring of the outer cylinder lower ring 204 with the outer edge of the workbench 2, and clamp and fix the outer cylinder lower ring 204 with the third clamping mechanism 6;

[0043] Step 3: Place the guide plate 202 on the support seat 7, with the concave part of the guide plate 202 close to the wedge-shaped platform 71, and insert the end of the guide plate 202 with the round boss into the corresponding round hole in the middle of the inner cylinder 201 for positioning and spot welding;

[0044] Step 4: assemble the rib plate on the upper side of the outer cylinder lower ring 204, and place the outer cylinder upper ring 203 on the assembled rib plate, and clamp and fix it with the second clamping mechanism 5 to complete the assembly of the gas guide device.

[0045] During the assembly process, the inner cylinder 201, the outer cylinder upper ring 203, and the outer cylinder lower ring 204 are kept coaxially arranged.
