According to the technical scheme of the utility model: the utility model provides a cylinder catalytic muffler is at location flaring mechanism of double loop welding process which characterized in that: the adjustable clamp comprises a base, wherein an annular bulge extending along the axial direction is arranged on one side end face of the base, and an adjusting gasket and a conical ring are sequentially sleeved on the bulge;

the outer lane equipartition of the axial terminal surface of base sets up a plurality of step hole, every all set up the spring in the step hole, the step hole sets up the holding ring corresponding to bell ring one side, and the step hole axial other end sets up the guide bar, the guide bar passes step hole and holding ring fixed connection, and the guide bar is kept away from holding ring pot head and is established the uide bushing, and the outer terminal surface of uide bushing sets up the stopper, stopper and guide bar fixed connection.

As a further improvement of the utility model, the inner ring of the conical ring is tightly connected with the convex part.

As a further improvement of the present invention, the positioning ring can compress the spring to realize the axial reciprocating movement in the step hole.

As a further improvement of the utility model, a gap is left between the inner wall of the positioning ring and the outer ring of the conical ring.

The technical effects of the utility model reside in that: the utility model discloses the product is rational in infrastructure ingenious, can not increase the process and not lead to the fact under the prerequisite of any influence to the double circular seam welding process, carry out the flaring to the noise elimination mouth of pipe that has warp, guarantee that the assembly of later process is smooth and easy, and the beat is stable.

Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings.

In fig. 1 to 3, the workpiece positioning device comprises a first workpiece 1, a second workpiece 2, a positioning ring 3, a conical ring 4, an adjusting gasket 5, a spring 6, a guide rod 7, a guide sleeve 8, a limiting block 9, a base 10 and the like.

As shown in fig. 1 to 3, the present invention relates to a positioning flaring mechanism of a cylinder type catalytic muffler in a double circular seam welding process, which comprises a base 10, wherein a side end surface of the base 10 is provided with an annular protrusion 10-2 extending along an axial direction, and the protrusion 10-2 is sequentially sleeved with an adjusting gasket 5 and a conical ring 4;

the outer ring of the axial end face of the base 10 is uniformly provided with a plurality of step holes 10-1, each step hole 10-1 is internally provided with a spring 6, one side of each step hole 10-1 corresponding to the conical ring 4 is provided with a positioning ring 3, the axial other end of each step hole 10-1 is provided with a guide rod 7, the guide rod 7 penetrates through the step hole 10-1 and is fixedly connected with the positioning ring 3, one end of the guide rod 7, far away from the positioning ring 3, is sleeved with a guide sleeve 8, the outer end face of the guide sleeve 8 is provided with a limiting block 9, and the limiting block 9 is fixedly connected with the guide rod 7.

The inner ring of the conical ring 4 is fixedly connected with the bulge part 10-2, the positioning ring 3 can compress the spring 6 to realize axial reciprocating movement in the stepped hole 10-1, and a gap is reserved between the inner wall of the positioning ring 3 and the outer ring of the conical ring 4.

As shown in figures 1-3, the utility model discloses the working process of product is as follows: the second workpiece 2 (the silencing pipe component) is fixed on the positioning ring 3 through a magnet, at the moment, the silencing pipe 2-1 of the second workpiece 2 is not contacted with the conical ring 4, and the first workpiece 1 acted by external force is used for sleeving the second workpiece 2 and moving along the direction of the acting force. Because the spring force is far smaller than the acting force applied to the first workpiece 1, when the first workpiece 1 contacts the second workpiece 2 or the friction force between the first workpiece 1 and the second workpiece 2 is larger than the spring force, the second workpiece 2 drives the positioning ring 3 to move towards the base 10, the muffler pipe 2-1 is flared by the conical ring 4, and the thickness of the adjusting gasket 5 influences the diameter of the flared muffler pipe orifice of the second workpiece 2. In the process, the second workpiece 2 is always coaxial with the base 10 due to the positioning effect of the guide rod 7. The final state of operation is that the positioning ring 3 is pressed against the base 10, the first workpiece 1 is pressed into the set position, and welding is performed at the joint by the welding equipment. During welding operation, the support frames respectively arranged at the two axial ends of the surface of the second workpiece 2 play an effective supporting role for the first workpiece 1 (cylinder).

After the welding is finished, the acting force F disappears, and the spring separates a combined piece formed by welding the first workpiece 1 and the second workpiece 2 from the conical ring to play a role in discharging.
