When the positioning frame 3 needs to be removed from the bottom plate 1, the positioning frame 3 is pulled to pull the plug-in blocks 6 out of the slots 5. When the positioning frame 3 needs to be fixed on the bottom plate 1, the plug-in blocks 6 are inserted into the slots 5. The fixed connection between the positioning frame 3 and the bottom plate 1 is realized by the plug-in cooperation between the plug-in blocks 6 and the slots 5.

[0036] The top of the positioning frame 3 is concave to form a U-shaped positioning groove 7, and the positioning groove 7 extends to both sides of the positioning frame 3. A pressing component 8 is provided on the positioning groove 7. Of course, there can be two pressing components 8, and the two pressing components 8 are distributed along the width direction of the positioning groove 7. The pressing component 8 is used to press the intake pipe 9 to prevent the intake pipe 9 from deviating upward;

[0037] The pressing component 8 includes a groove 81, a spring piece 82 and a pushing member 83. The groove 81 is arranged on the inner wall of the positioning groove 7. The spring piece 82 is bow-shaped. The two ends of the spring piece 82 are arranged up and down. The two ends of the spring piece 82 are inserted into the groove 81.

When it is necessary to increase the length of the spring piece 82 extending into the positioning groove 7, the second screw is rotated to make the second screw descend on the positioning frame 3. The descent of the second screw pushes the first connecting rod 84 to descend in the strip groove 86, and compresses the spring piece 82 to produce deformation, and at the same time drives the second connecting rod 85 to rotate. The distance between the two ends of the spring sheet 82 is reduced, and the length of the spring sheet 82 along the width direction of the positioning groove 7 is increased, that is, the length of the spring sheet 82 extending into the positioning groove 7 is increased. When it is necessary to reduce the length of the spring sheet 82 extending into the positioning groove 7, the second screw is rotated in the opposite direction to raise the second screw.

[0038] The air intake pipe 9 includes a first pipe section 91, a second pipe section 92 and a third pipe section 93. One end of the first pipe section 91 is an inclined surface and the other end is a plane. The plane where the plane end of the first pipe section 91 is located is perpendicular to the first pipe section 91. One end of the second pipe section 92 is an inclined surface and the other end is a plane. The plane where the plane end of the second pipe section 92 is located is perpendicular to the second pipe section 92. One end of the third pipe section 93 is an inclined surface and the other end is a plane. The plane where the plane end of the third pipe section 93 is located is perpendicular to the third pipe section 93. The first pipe section 91 and the second pipe section 92 are perpendicular to each other. The first pipe segment 91 and the third pipe segment 93 are connected by a third connecting segment 95, and the two ends of the second connecting segment 94 are inclined surfaces. The two inclined surface ends of the second connecting segment 94 are matched and connected with the inclined surface end of the first pipe segment 91 and the inclined surface end of the second pipe segment 92 respectively. The first pipe segment 91 and the third pipe segment 93 are connected by a third connecting segment 95, and the two ends of the third connecting segment 95 are an inclined surface and an arc surface respectively. The arc surface end of the third connecting segment 95 is matched and connected with the outer peripheral wall of the first pipe segment 91, and the inclined surface end of the third connecting segment 95 is matched and connected with the inclined surface end of the third pipe segment 93;

[0039] During the welding process of the air intake pipe 9, the three positioning plates 2 correspond to the first pipe section 91, the second pipe section 92 and the third pipe section 93 respectively, wherein two positioning frames 3 among the four positioning frames 3 correspond to the first pipe section 91, and the other two positioning frames 3 correspond to the second pipe section 92 and the third pipe section 93 respectively;

[0040] First, the first tube section 91 is positioned, and the first tube section 91 is sequentially placed into the grooves 81 on the two corresponding positioning frames 3. During the placement process, the first tube section 91 is inserted into the grooves 81 from top to bottom. During the insertion process, the first tube section 91 pushes the spring piece 82 to deform. When the bottom of the first tube section 91 abuts against the groove 81, the first tube section 91 is separated from the spring piece 82. At this time, the spring piece 82 recovers under the action of elasticity and abuts against the first tube section 91 again. The abutting position of the spring piece 82 and the first tube section 91 is higher than the axis of the first tube section 91. In this way, the spring piece 82 is pressed against the first tube section 91. 1 generates downward pressure to achieve the compression of the first pipe segment 91, to achieve the positioning of the upper and lower positions of the first pipe segment 91, to prevent the first pipe segment 91 from shifting upward and affecting the welding accuracy, and in fact, the groove width of the groove 81 is equal to the outer diameter of the first pipe segment 91, to achieve the positioning of the first pipe segment 91 in a direction parallel to the width of the groove 81, and then, the plane end of the first pipe segment 91 is fitted with the corresponding positioning plate 2 to achieve the positioning of the length direction of the first pipe segment 91, wherein, according to actual needs, the length of the spring piece 82 extending into the groove 81 can be adjusted to adjust the compression force of the spring piece 82 corresponding to the first pipe segment 91;

[0041] Next, the second pipe section 92 is positioned and placed into the groove 81 on the corresponding positioning frame 3 in the same manner as the first pipe section 91. The flat end of the second pipe section 92 is then fitted with the corresponding positioning plate 2. Subsequently, the two inclined ends of the second connecting section 94 are respectively fitted with the inclined ends of the first pipe section 91 and the inclined ends of the second pipe section 92. Then, the first pipe section 91, the second connecting section 94, and the second pipe section 92 are fixed by spot welding.

[0042] Secondly, the third pipe section 93 is positioned. The positioning method of the third pipe section 93 is the same as the positioning method of the second pipe section 92.

[0043] Here, the position of the positioning plate 2 on the guide rod 41 is adjusted according to the actual lengths of the first pipe section 91, the second pipe section 92 and the third pipe section 93;

[0044] Finally, the first pipe section 91, the second pipe section 92, the third pipe section 93, the second connecting section 94 and the third connecting section 95 which have been fixed to each other by spot welding are removed from the welding tool and fully welded;

[0045] In summary, the elastic sheet applies a downward force to the intake pipe 9 to avoid the intake pipe 9 from being offset in the up and down directions, thereby improving the welding accuracy of the intake pipe 9. Moreover, by adjusting the position of the positioning plate 2 on the guide rod 41, it is also convenient to weld intake pipes 9 of different sizes.

[0046] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
