[0036] This welding tool is mainly used for welding operations between the clamshell catalyst 520 and the exhaust manifold 510 and the exhaust tail pipe 530;

[0037] The welding tool comprises a tool base 100, and a detection assembly 600 is installed on one side of the tool base 100, and the detection assembly 600 is used to detect two ports of the clamshell catalyst 520;

[0038] Specific inspection items include but are not limited to the flatness and size of the port.

The welding surfaces between the clamshell catalyst 520 and the connection ends of the exhaust manifold 510 and the exhaust tail pipe 530 are kept tight to improve the welding accuracy.

[0039] The detection assembly 600 includes a bracket, a claw clamping assembly 610, a lower connecting pipe 620 and a plugging fitting 630. The lower connecting pipe 620 is installed on the tooling base 100. The claw clamping assembly 610 is vertically installed on one side outer wall of the bracket. The plugging fitting 630 is installed on the other side outer wall of the bracket. The clamshell catalyst 520 is vertically arranged in the detection assembly 600. One end port of the clamshell catalyst 520 is connected to the lower connecting pipe 620. The plugging fitting 630 is sealed to the other end port of the clamshell catalyst 520 by adjustment.

[0040] The claw clamping assembly 610 includes a first clamping cylinder 611 and a second clamping cylinder 612. The first clamping cylinder 611 and the second clamping cylinder 612 are provided with locking members at the mounting positions of the bracket.

The outer side walls of the lower connecting pipe 620 and the detection die head 632 are both provided with a gas leakage detection sensor;

[0044] In one embodiment of the present invention, the pressure sensor and the gas leakage detection sensor are both prior art, and their working principles are not described in detail.

[0045] When the lower connecting pipe 620, the detection die head 632 and the two ports on the clamshell catalyst 520 are connected respectively, the detection gas is introduced. If there are defects on the two ports of the clamshell catalyst 520, they will be detected by the gas leakage detection sensor, and then the connection sealing degree of the connected clamshell catalyst 520 can be simulated;

[0046] The detection assembly 600 can be used to check whether the angle and parallelism of the port of the clamshell catalyst 520 meet the requirements, so as to ensure the accuracy and stability of the connection during the welding process;

[0047] During the welding process, the angles of the connection ends of the clamshell catalyst 520, the exhaust tail pipe 530 and the exhaust manifold 510 are also adjusted through the middle section support assembly 400, the exhaust tail pipe connection assembly 300 and the exhaust manifold connection assembly 200;

[0048] The middle section support assembly 400 includes a pipe support seat 410 and a catalyst support seat 420, wherein a hanging claw 522 support structure is provided on one side of the catalyst support seat 420, and a clamp is provided at the top of the pipe support seat 410 and the catalyst support seat 420, and the top of the catalyst support seat 420 can keep the clamshell catalyst 520 in a horizontal position;

[0049] It should be noted that the top clamp of the pipe support seat 410 can support the exhaust tail pipe 530 and the exhaust manifold 510, so that the ports of the exhaust tail pipe 530 and the exhaust manifold 510 can correspond to the positions of the connection ends of the exhaust tail pipe connection assembly 300 and the exhaust manifold connection assembly 200 respectively;

[0050] The exhaust manifold connection assembly 200 includes a first sliding seat 230, a coupling flange 210, a coupling cylinder 220 and a lateral deflection cylinder 240. The first sliding seat 230 is mounted with a first sliding frame, the lateral deflection cylinder is mounted on the top outer wall of the first sliding frame, a flange bracket is mounted on the movable end of the lateral deflection cylinder, the coupling cylinder 220 is mounted on the flange bracket, and the coupling flange 210 is mounted on the movable end of the coupling cylinder 220.

[0051] The combined flange 210 includes a magnetic flange 211, a deflection clamping claw 212 and a servo motor 213. The servo motor 213 is mounted on the flange bracket, and the deflection clamping claw 212 is mounted on the output shaft of the servo motor 213. The magnetic flange 211 and the mounting flange 511 have the same specifications. Both ends of the magnetic flange 211 and the mounting flange 511 are provided with claw holes, and the end of the deflection clamping claw 212 is inserted into the claw hole.

[0052] The exhaust tail pipe connection assembly 300 includes a second sliding seat 320, a pressing clamp 330, an angle deflection cylinder 340 and a tail pipe supporting die head 310. The second sliding seat 320 is mounted with a second sliding frame, the angle deflection cylinder 340 is mounted on the second sliding frame, the tail pipe supporting die head 310 is mounted on the movable end of the angle deflection cylinder 340, the pressing clamp 330 is mounted on the top outer wall of the second sliding frame, and the pressing clamp 330 can be pressed on the top outer wall of the exhaust tail pipe 530.

[0053] It should be noted that when the exhaust manifold 510 and the exhaust tail pipe 530 are welded, they need to be connected to the exhaust manifold 510 and the exhaust tail pipe 530 through the exhaust manifold connecting assembly 200 and the exhaust tail pipe connecting assembly 300. The two ports can be locked by the exhaust manifold connecting assembly 200 and the exhaust tail pipe connecting assembly 300 to put the exhaust manifold 510 and the exhaust tail pipe 530 in a tensioned state, even if the pipe part in the workpiece 500 is subjected to a certain tensile or compressive force, so that it is in a tense state;

[0054] When the exhaust manifold 510 and the exhaust tail pipe 530 are connected to the clamshell catalyst 520, stress concentration areas are easily generated during the welding process due to the influence of welding thermal stress. If the pipe is in a tensioned state, the thermal stress generated by welding can be partially offset, reducing the stress concentration phenomenon and increasing the fatigue life of the pipe.

[0055] The automobile processing welding tool is used for welding work on the workpiece 500, specifically:

[0056] Before welding, the clamshell catalyst 520 is pre-tested by the detection assembly 600, and the clamshell catalyst 520 is vertically placed in the detection assembly 600, wherein one end of the hanging claw 522 faces upward, and the end of the hanging claw 522 faces one side of the hanging claw clamping assembly 610, and the hanging claw 522 is clamped by the hanging claw clamping assembly 610, specifically, the first clamping cylinder 611 and the second clamping cylinder 612 drive the clamping ends of the ends thereof to clamp on the outer wall of the hanging claw 522;

[0057] The bottom end port of the clamshell catalyst 520 is sleeved on the lower connecting pipe 620;

[0058] The lifting and rotating cylinder 631 is rotated 90 degrees, and the detection die head 632 is pressed down to another port of the clamshell catalyst 520 along the vertical direction. At this time, the detection die head 632 is pressed onto the port of the clamshell catalyst 520;

[0059] The detection die head 632 can detect the flatness and size of the port. During the detection process, if the port is in an irregular shape, it will be detected. Specifically, the circumferential pressure is detected by a pressure sensor. If the pressure is consistent, it means that the port is a standard structure.

[0060] The detection die head 632 in the detection assembly 600 and the lower connecting pipe 620 are fed with detection gas, and the state of the connection of the clamshell catalyst 520 is checked by the detection gas to see if there is leakage;

[0061] Place the clamshell catalyst 520 horizontally on the pipe support seat 410. The clamp on the pipe support seat 410 can maintain the clamshell catalyst 520 in a horizontal state. At this time, the hanging claw 522 on the clamshell catalyst 520 can be placed on the hanging claw 522 support structure;

[0062] The exhaust manifold 510 and the exhaust tail pipe 530 are placed on the pipe support seat 410, the exhaust manifold 510 is installed on the side close to the exhaust manifold connection assembly 200, and the exhaust tail pipe 530 is installed on the side close to the exhaust tail pipe connection assembly 300;

[0063] By connecting the flange 210 to the mounting flange 511, the magnetic flange 211 is connected to the mounting flange 511, and the servo motor 213 drives the deflection clamp 212 to press the connection end of the magnetic flange 211 and the mounting flange 511, so that the exhaust manifold 510 is twisted at an angle, and the end of the exhaust manifold 510 away from the mounting flange 511 corresponds to the port of the clamshell catalyst 520, and the plug is welded;

[0064] The mounting flange 511 of the exhaust manifold 510 is combined with the magnetic flange 211 by the first sliding seat 230 moving along the length direction of the tooling base 100, and at the same time, the lateral offset cylinder 240 drives the first sliding frame to move along the length direction perpendicular to the tooling base 100, so that the mounting flange 511 and the magnetic flange 211 are installed correspondingly;

[0065] Similarly, the exhaust tail pipe 530 corresponds to the other port of the clamshell catalyst 520, and the welding operation is performed. The end of the exhaust tail pipe 530 is plugged and combined with the tail pipe support die head 310. The port of the tail pipe support die head 310 is an oblique structure. Under the support of the pipe support seat 410, the port of the tail pipe support die head 310 and the end port of the exhaust tail pipe 530 can be tightly combined. When plugging, the pressing clamp 330 is pressed on the outer wall of the exhaust tail pipe 530 to form a state of stably clamping the exhaust tail pipe 530. At this time, the exhaust tail pipe 530 is plugged and connected with the clamshell catalyst 520;

[0066] The second sliding seat 320 drives the second sliding frame to move along the length direction of the tooling base 100, and the angle deflection cylinder 340 can drive the tail pipe supporting die head 310 to deflect a certain angle to ensure that the port of the tail pipe supporting die head 310 can be tightly combined with the end port of the exhaust tail pipe 530;

[0067] The ports after insertion can be circularly welded by means of a welding machine head, so that the connection between the clamshell catalyst 520 and the exhaust manifold 510 and the exhaust tail pipe 530 is welded and sealed, thereby realizing the welding formation of the exhaust pipe assembly.

[0068] The above describes an embodiment of the present embodiment, but the present embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, all of which are within the protection of the present embodiment.
