[0003] In view of the deficiencies in the prior art, the present invention provides a double-gun ring welding machine for welding silencers of automobiles to solve the problems raised in the above background technology.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A double-gun ring welding machine for automobile welding silencers, comprising a control device, a platform is fixedly connected to the top of the control device, a double-gun welding device is fixedly connected to the outer wall of the control device, a placement plate is fixedly connected to the top of the platform, and a recoil mechanism is fixedly connected to the inner wall of the control device; The recoil mechanism comprises: A first bearing, wherein holes are provided on the outer wall of the placement plate and the top of the control device, and the first bearing is fixedly connected in the hole of the placement plate; A workbench, the workbench being rotatably connected to an outer wall of the first bearing; A round rod is fixedly connected to the bottom of the workbench, a movable rod is rotatably connected to the top of the workbench, and a baffle is fixedly connected to the top of the workbench.

[0005] Preferably, a motor is fixedly connected to the inner bottom of the control device, and the motor drives the workbench to rotate, and the material is driven to rotate along with the rotation. The rotation of the material detects the firmness of the material under the pull of its centrifugal force, and the effect of the centrifugal force is utilized to detect the firmness of the material. Effective firmness detection after welding avoids the subsequent loose welding and improves the qualified rate of the workpiece. The top of the motor is rotatably connected to a rotating shaft.

[0006] Preferably, a threaded rod is fixedly connected to the top of the rotating shaft. The motor drives the threaded rod to rotate counterclockwise for one circle and then immediately rotates clockwise for one circle. When the threaded rod rotates clockwise, the threaded rod is threadedly connected to the slider, which will drive the slider on the slide rail to rise. At this time, the vertical rod will be driven to rise. The rising vertical rod is stuck in the ring, which will immediately stop the rotation of the workbench. During the counterclockwise rotation of the workbench, the material is driven to rotate and then the rotation is immediately stopped, which will cause tearing effect on the material under inertia. The inertia generated by the material during the rotation process is used to test the firmness of the material. Effective firmness testing after welding avoids the subsequent loose welding and improves the qualified rate of the workpiece. The top of the threaded rod is fixedly connected to a first spring.

[0007] Preferably, a collar is fixedly connected to the top of the first spring, and the top of the collar is fixedly connected to the bottom of the round rod.

[0008] Preferably, the inner wall of the control device is fixedly connected with a slide rail, the inner wall of the slide rail is slidably connected with a slider, the slider is also sleeved on the outer wall of the rotating shaft, the inner wall of the slider is provided with a thread, and the slider is in movably contact with the threaded rod.

[0009] Preferably, a vertical rod is fixedly connected to the top of the slider, the vertical rod is inserted into the collar, and a second spring is fixedly connected between the bottom of the slider and the inner wall of the control device.

[0010] Preferably, a third bearing is fixedly connected to the top of the workbench, a first clamping plate is rotatably connected to the top of the third bearing, and a first bolt is threadedly connected to the top of the first clamping plate.

[0011] Preferably, the outer wall of the baffle is fixedly connected to a sliding rod, the outer wall of the sliding rod is slidably connected to a sliding block, the outer wall of the sliding block is threadedly connected to a third bolt, the top of the sliding block is fixedly connected to a second clamping plate, and the top of the second clamping plate is threadedly connected to a second bolt.

[0013] Preferably, the outer wall of the knocking plate is fixedly connected with a connecting rod, and the workbench is used to drive the baffle to rotate. When the gravity plate rotates to the position of the vertical plate, the vertical plate lifts the gravity plate, driving the knocking plate to lift up, and then the knocking plate hits the material when it falls, so as to detect the firmness of the material and combine it with the inspection of the material during the workbench process. The firmness of the material is tested from different aspects to ensure the inspection of the material. The outer wall of the connecting rod is fixedly connected with the gravity plate, and the top of the workbench is fixedly connected with the vertical plate. The gravity plate is in active contact with the vertical plate.

[0014] The present invention provides a double-gun ring welding machine for automobile welding silencers, which has the following beneficial effects: 1. The double-gun ring welding machine used for automobile muffler welding drives the workbench to rotate through the motor. During the rotation, the material will be driven to rotate with it. The material is pulled by the centrifugal force, and the centrifugal force is used to detect the firmness of the material. After welding, the firmness is effectively detected, which avoids the subsequent loose welding and improves the qualified rate of the workpiece.

[0015] 2. The double-gun ring welding machine used for welding silencers of automobiles drives the threaded rod to rotate counterclockwise for one circle through the motor, and then immediately rotates clockwise for one circle. When the threaded rod rotates clockwise, the threaded rod is threadedly connected to the slider, which will drive the slider on the slide rail to rise. At this time, it will drive the vertical rod to rise. The vertical rod rises and gets stuck in the ring, which will immediately stop the rotation of the workbench. During the counterclockwise rotation of the workbench, the material is driven to rotate, and then the rotation is stopped immediately, which will tear the material under inertia. The inertia generated by the material during the rotation process is used to test the firmness of the material. Effective firmness testing after welding can avoid the subsequent loose welding and improve the qualified rate of workpieces.

[0016] 3. The double-gun ring welding machine used for automobile welding silencers uses the workbench to drive the baffle to rotate. When the gravity plate rotates to the position of the vertical plate, the vertical plate lifts the gravity plate, driving the knocking plate to lift up, and then the knocking plate hits the material when it falls, to detect the firmness of the material. Combined with the inspection of the material during the workbench process, the firmness of the material is tested from different aspects to ensure the inspection of the material.

DETAILED DESCRIPTION

[0021] For example, see Figure 1-5 The present invention provides a technical solution: a double-gun ring welding machine for automobile welding silencers, comprising a control device 1, a platform 2 is fixedly connected to the top of the control device 1, a double-gun welding device 4 is fixedly connected to the outer wall of the control device 1, a placement plate 3 is fixedly connected to the top of the platform 2, and a recoil mechanism 7 is fixedly connected to the inner wall of the control device 1; The recoil mechanism 7 comprises: A first bearing 72, the outer wall of the placement plate 3 and the top of the control device 1 are provided with holes, and the first bearing 72 is fixedly connected in the hole of the placement plate 3; A workbench 71, the workbench 71 is rotatably connected to an outer wall of a first bearing 72; The round rod 73 is fixedly connected to the bottom of the workbench 71 , the top of the workbench 71 is rotatably connected to the movable rod 6 , and the top of the workbench 71 is fixedly connected to the baffle 5 .

[0022] The inner bottom of the control device 1 is fixedly connected to a motor 712 , and the top of the motor 712 is rotatably connected to a rotating shaft 76 .

[0023] A threaded rod 75 is fixedly connected to the top of the rotating shaft 76 , and a first spring 74 is fixedly connected to the top of the threaded rod 75 .

[0024] A collar 77 is fixedly connected to the top of the first spring 74 , and the top of the collar 77 is fixedly connected to the bottom of the round rod 73 .

[0025] The inner wall of the control device 1 is fixedly connected with a slide rail 79 , and the inner wall of the slide rail 79 is slidably connected with a slider 710 . The slider 710 is also sleeved on the outer wall of the rotating shaft 76 . The inner wall of the slider 710 is provided with threads, and the slider 710 is in active contact with the threaded rod 75 .

[0026] A vertical rod 78 is fixedly connected to the top of the slider 710 , and the vertical rod 78 is inserted into the collar 77 . A second spring 711 is fixedly connected between the bottom of the slider 710 and the inner wall of the control device 1 .

[0027] The top of the workbench 71 is fixedly connected to the third bearing 11 , the top of the third bearing 11 is rotatably connected to the first clamping plate 10 , and the top of the first clamping plate 10 is threadedly connected to the first bolt 9 .

[0028] The outer wall of the baffle 5 is fixedly connected to a sliding rod 12, the outer wall of the sliding rod 12 is slidably connected to a sliding block 13, the outer wall of the sliding block 13 is threadedly connected to a third bolt 16, the top of the sliding block 13 is fixedly connected to a second clamping plate 14, and the top of the second clamping plate 14 is threadedly connected to a second bolt 15.

[0029] When in use, the control device 1 can control the operation of each device, place the material to be welded on the workbench 71, place one side of the welding material in the first clamping plate 10, then rotate the first bolt 9 to fix the material, and place the other side of the material in the second clamping plate 14. The sliding block 13 is located on the slide rod 12 and can move. Then, the second clamping plate 14 is pressed onto the material, and finally, the third bolt 16 is tightened to fix the sliding block 13, and the second bolt 15 is rotated to fix the material in the second clamping plate 14, and then the double-gun welding device 4 is picked up to weld the material; After welding is completed, Figure 8 As shown, the second bolt 15 and the third bolt 16 are rotated to loosen, and the sliding block 13 is pushed to move the second clamping plate 14 away from the material, so that the material will not collide with the second clamping plate 14 during the shaking process; Combined with Figure 5 As shown, the motor 712 is powered on and started, and the motor 712 drives the threaded rod 75 to rotate through the rotating shaft 76. The threaded rod 75 is spirally upward, and then when the threaded rod 75 rotates counterclockwise, the first spring 74 pulls the workbench 71 on the round rod 73 to rotate. When the workbench 71 rotates, it drives the material to rotate with it. The rotation of the material is pulled by its centrifugal force to detect the firmness of the material; Combined with Figure 5 and 7 As shown, the first clamping plate 10 fixes one side of the material, and then the third bearing 11 is set to allow the material to rotate. The motor 712 drives the threaded rod 75 to rotate counterclockwise for one circle, and then immediately rotates clockwise for one circle. The elastic length of the second spring 711 is greater than the distance between the slide rail 79 and the inner wall of the control device 1. Therefore, under the pressure of the second spring 711, the slider 710 continues to fit on the threaded rod 75. Then, when the threaded rod 75 rotates counterclockwise, the threads of the threaded rod 75 and the inner wall of the slider 710 are opposite. Then, when the threaded rod 75 rotates clockwise, the threaded rod 75 is threadedly connected with the slider 710, and then the slider 710 located on the slide rail 79 will be driven to rise. At this time, the vertical rod 78 will be driven to rise. The vertical rod 78 rises and is stuck in the ring 77, which will immediately stop the rotation of the workbench 71. During the counterclockwise rotation of the workbench 71, the material is driven to rotate. Then, the rotation is immediately stopped, which will tear the material under inertia, thereby testing the firmness of the material. The subsequent motor 712 drives the threaded rod 75 to rotate counterclockwise again, which drives the slider 710 located on the threaded rod 75 to descend.

[0030] For example 3, please refer to Figure 1-9 Based on the first and second embodiments, the present invention provides a technical solution: The outer wall of the baffle 5 is fixedly connected with a knocking mechanism 8 , which includes a second bearing 81 , the outer wall of the second bearing 81 is rotatably connected with the second bearing 81 , and the outer wall of the second bearing 81 is rotatably connected with a knocking plate 82 .

[0031] The outer wall of the knocking plate 82 is fixedly connected with a connecting rod 83 , the outer wall of the connecting rod 83 is fixedly connected with a gravity plate 84 , the top of the workbench 71 is fixedly connected with a vertical plate 85 , and the gravity plate 84 is in movable contact with the vertical plate 85 .

[0032] When in use, the knocking plate 82 is in a normally hanging state. When the workbench 71 drives the baffle 5 to rotate, when the gravity plate 84 rotates to the position of the vertical plate 85, the vertical plate 85 lifts the gravity plate 84, thereby driving the knocking plate 82 to lift up, and then the knocking plate 82 hits the material when falling, to test the firmness of the material. The repeated cyclic rotation of the workbench 71 will cause the gravity plate 84 to cyclically collide with the vertical plate 85.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
