By adjusting the fuel injection through feedback signals, they ensure that the engine operates in the best state, reduce environmental pollution. When encapsulating and welding the produced oxygen sensors, a welding device is required for the welding operation.

[0003] Chinese Patent with publication number CN115106701A discloses an oxygen sensor welding device, belonging to the field of oxygen sensor manufacturing machinery. An oxygen sensor welding device includes a workbench, on the top of which an L-shaped plate is fixed. A positioning component for driving the L-shaped plate to move is arranged on the surface of the workbench. Inside the L-shaped plate, a rotating disk is rotatably connected through a bearing. A clamping component for limiting the workpiece is arranged on the rotating disk. A flipping component for driving the clamping component to rotate is arranged on the rotating disk. A side plate is fixed on the top of the workbench, and a filtering component for purifying peculiar smell is arranged on the surface of the side plate. This patent has a relatively simple structure, is convenient and practical, effectively improves the accuracy of workpiece encapsulation welding processing, and can well clamp and fix the workpiece during welding and can be flipped at any time, effectively improving the working efficiency of the equipment. It can also filter and purify the smoke generated during the welding operation to protect the environment of the work site.

[0004] However, the current welding device has the following problems: After installing and welding the oxygen sensor, it is not convenient to continuously clamp the oxygen sensor accessories for welding operations. Frequently manually adjusting the position of the oxygen sensor to be welded will prolong the welding operation time for each oxygen sensor and reduce the production efficiency. Therefore, we propose an installation welding device for automotive oxygen sensors. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides an installation welding device for automotive oxygen sensors, which solves the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: An installation and welding device for an automotive oxygen sensor includes a processing table. Above the processing table, there is welding equipment. On the top of the processing table, there is a continuous device. The continuous device includes two fixed frames fixed on the top of the processing table, a grooved roller rotatably installed between the two fixed frames, and a servo motor for driving the grooved roller to rotate. In the middle of the outer wall of the grooved roller, there is a welding positioning line. On the outside of the grooved roller, there are several grooves. On one side of each of the several grooves of the grooved roller, there is a turntable rotatably installed. On the other side of each of the several grooves of the grooved roller, there is a fixed disk. On the outer wall of a single turntable, there is a threaded ring. Inside the threaded ring, there is a screw threadedly connected. In the middle of the outer walls of several other turntables, there are connecting columns fixed. On the end faces of the screw and several connecting columns, there is a chuck one. The outer wall of the fixed disk is penetrated and slidably installed with a sliding column. On the outside of the sliding column, there is a T-shaped disk, and there is a spring between the T-shaped disk and the fixed disk. On the end face of the sliding column, there is a chuck two. On the side of the grooved roller, there is a driving component. The driving component includes a driving motor, a large friction ring, and several small friction rings. The driving motor is embedded at an eccentric position on the side of the grooved roller. The output end of the driving motor is fixed with a friction disk. The large friction ring is rotatably installed on the outer wall of the grooved roller. Several small friction rings are respectively fixed on the sides of several turntables away from the chuck one. The outer wall of the friction disk is in contact with the inner wall of the large friction ring. The outer wall of the large friction ring is in contact with the outer walls of the small friction rings. On the side of the chuck one close to the turntable, there is a connecting ring. The connecting ring is rotatably connected with several chucks one. Inside the grooved roller, there is a sliding groove for the connecting ring to slide. The chuck one and the chuck two are arranged opposite to each other. The staff pulls the sliding column. The sliding column drives the T-shaped disk and the chuck two to move away from the center of the grooved roller. Place the two automotive oxygen sensor accessories to be welded into the grooves of the grooved roller. Release the sliding column. Under the elastic force of the spring corresponding to the T-shaped disk, the T-shaped disk drives the chuck two to reset through the sliding column. At this time, the two automotive oxygen sensor accessories are clamped and fixed between the chuck two and the chuck one. Drive several chucks one to rotate in the grooves of the grooved roller through the driving component, so that the automotive oxygen sensor accessories clamped by the chuck one and the chuck two rotate, thereby realizing circular welding of the two automotive oxygen sensor accessories. At the same time, the staff can observe whether the welding positioning line opened in the middle of the grooved roller corresponds to the welding gap of the two automotive oxygen sensor accessories. When the welding positioning line does not correspond to the welding gap of the two automotive oxygen sensor accessories, rotate the screw. The screw is affected by the thread of the threaded ring. The threaded ring controls the screw to drive the chuck one to move away from or close to the turntable, thereby controlling the position of the two automotive oxygen sensor accessories between the chuck two and the chuck one, so as to ensure that the welding positioning line opened in the middle of the grooved roller corresponds to the welding gap of the two automotive oxygen sensor accessories.

[0007] According to the above technical solution, a material pushing device is provided at the grooved roller. The material pushing device includes an L-shaped sliding plate, an L-shaped pushing plate, and a raised ring. A plurality of square holes are evenly arranged in the circumferential direction on the outer wall of the grooved roller. A through hole is provided in the middle of the groove of the grooved roller, and the through hole of the grooved roller is communicated with the inside of the square hole. The L-shaped sliding plate is slidably installed inside the square hole of the grooved roller, and a spring is provided between the L-shaped sliding plate and the outer wall of the grooved roller. The L-shaped pushing plate is slidably installed inside the through hole of the grooved roller. The L-shaped sliding plate and the L-shaped pushing plate are hingedly connected by a hinge rod. The raised ring is fixed to the outer wall of the fixed frame on one side through a bracket. A spherical ball is fixed to the side of the L-shaped sliding plate away from the L-shaped pushing plate. An arc-shaped protrusion is fixed to the lower side of the rear of the raised ring. The arc-shaped protrusion of the raised ring is located on the movement track of the spherical ball of the L-shaped sliding plate. When the grooved roller rotates, it will drive the L-shaped sliding plate to rotate. When the spherical ball of the L-shaped sliding plate moves to the position of the arc-shaped protrusion of the raised ring, the arc-shaped protrusion of the raised ring pushes the spherical ball of the L-shaped sliding plate to drive the L-shaped sliding plate to move towards the turntable. The corresponding spring of the L-shaped sliding plate is compressed, and the L-shaped sliding plate pushes the hinge rod to drive the L-shaped pushing plate to move along the inner wall of the through hole of the grooved roller in a direction away from the center of the grooved roller, so that the L-shaped pushing plate pushes the welded automotive oxygen sensor fittings out between chuck two and chuck one.

[0008] According to the above technical solution, the material pushing device further includes a U-shaped sliding rod, a Y-shaped rod, and a slot plate. The U-shaped sliding rod is slidably installed on the inner wall of the groove of the grooved roller. The Y-shaped rod is fixed to the side of the U-shaped sliding rod close to the center of the grooved roller, and the Y-shaped rod is arranged inside the I-shaped plate. The slot plate is fixed to the side of the L-shaped sliding plate close to the L-shaped pushing plate. A plurality of slots are provided at the top of the slot plate. The Y-shaped rod is inserted into a single slot of the slot plate. A sliding groove for the Y-shaped rod to slide is provided on the inner wall of the groove of the grooved roller. At the same time, during the movement of the L-shaped sliding plate, it will also push the slot plate to move along. The slot plate drives the Y-shaped rod to move along. The Y-shaped rod pushes the I-shaped plate to drive the sliding column to move in a direction away from the center of the grooved roller, so that the sliding column no longer drives chuck two to clamp the automotive oxygen sensor fittings, which is beneficial for the welded automotive oxygen sensor fittings to be pushed out; every time the staff operates the sliding column to drive the I-shaped plate and chuck two away from the center of the grooved roller, it is necessary to pull up the U-shaped sliding rod, and the U-shaped sliding rod will drive the Y-shaped rod to disengage from the slot of the slot plate, and only then can the sliding column displace.

[0009] According to the above technical solution, an anti-displacement device is provided at the grooved roller. The anti-displacement device includes a plurality of connecting plates, a plurality of square rods, a plurality of inclined blocks, a plurality of long columns, two track groove rings, and a plurality of round blocks. The two track groove rings are respectively fixed on both sides of the top of the processing table. An annular track groove is provided on one side of the two track groove rings close to each other, and a U-shaped inclined groove is provided above the front side of the annular track groove. A plurality of rectangular grooves are evenly arranged on the outer circumference of the grooved roller. The plurality of inclined blocks are respectively slidably installed inside the rectangular grooves of the grooved roller. The plurality of long columns are respectively fixed on the sides of adjacent two inclined blocks away from each other. The plurality of square rods are evenly fixed on the outer walls on both sides of the grooved roller. The plurality of connecting plates are respectively slidably installed outside the plurality of square rods. Hinged connecting rods are hinged on both sides of the connecting plate. One end of the hinged connecting rod away from the connecting plate is hinged on the end of the long column away from the inclined block. The plurality of round blocks are respectively fixed on one side of the plurality of connecting plates away from the grooved roller. The round blocks are slidably installed inside the annular track groove of the track groove ring. Four of the plurality of inclined blocks are in a group, and the inclined surfaces of the four inclined blocks are all arranged towards the groove direction of the grooved roller. After the two automotive oxygen sensor fittings are clamped and fixed between the second chuck and the first chuck, when the grooved roller rotates, it will drive the connecting plate and the round block to rotate through the square rod. When the round block moves to the U-shaped inclined groove position of the track groove ring, the U-shaped inclined groove of the track groove ring will guide the round block to drive the connecting plate to move along the outer wall of the square rod in a direction away from the center of the grooved roller. The connecting plate pulls one end of the hinged connecting rod to move together. The other end of the hinged connecting rod drives the inclined block to move along the rectangular groove of the grooved roller towards the direction of the automotive oxygen sensor fitting through the long column, so that the four inclined blocks apply a thrust to the two automotive oxygen sensor fittings, making the two automotive oxygen sensor fittings closely adhere to the groove of the grooved roller.

[0010] The present invention provides an installation and welding device for automotive oxygen sensors. It has the following beneficial effects:

[0011] (1) Through the setting of the continuous device, the driving component drives the automotive oxygen sensor fittings clamped by the first chuck and the second chuck to rotate, thereby realizing the circular welding of two automotive oxygen sensor fittings. When the previous group of automotive oxygen sensor fittings are being welded, the staff can place the next group of automotive oxygen sensor fittings in other grooves of the grooved roller, thus realizing the continuous welding operation of automotive oxygen sensor fittings. At the same time, the staff can observe whether the welding positioning line opened in the middle of the grooved roller corresponds to the welding gap between the two automotive oxygen sensor fittings. When the welding positioning line does not correspond to the welding gap between the two automotive oxygen sensor fittings, the staff can control the positions of the two automotive oxygen sensor fittings between the second chuck and the first chuck through the screw, threaded ring, and first chuck, so as to ensure that the welding positioning line opened in the middle of the grooved roller corresponds to the welding gap between the two automotive oxygen sensor fittings, thereby avoiding welding defects or errors caused by incorrect positions of the automotive oxygen sensor fittings, and improving the welding quality.

[0012] (2) Through the setting of the pushing device, the grooved roller, L-shaped slide plate, and raised ring cooperate to push the hinge rod to drive the L-shaped push plate to move along the inner wall of the through-port of the grooved roller in a direction away from the center of the grooved roller, so that the L-shaped push plate pushes the welded automotive oxygen sensor fittings out between the second chuck and the first chuck, thus greatly reducing the time of manual operation. Workers no longer need to manually move or handle the welded fittings, improving the production efficiency, and indirectly enhancing the work efficiency of the workers. At the same time, the second chuck no longer clamps the automotive oxygen sensor fittings under the cooperation of the L-shaped slide plate, slot plate, Y-shaped rod, I-shaped plate, and sliding column, which is conducive to the ejection of the welded automotive oxygen sensor fittings, and effectively prevents the automotive oxygen sensor fittings from being worn due to friction during the pushing process.

[0013] (3) Through the setting of the anti-misalignment device, the grooved roller, square rod, connecting plate, round block, hinge connecting rod, and long column cooperate to drive the inclined block to move along the rectangular groove of the grooved roller towards the automotive oxygen sensor fittings, so that the four inclined blocks exert a thrust on the two automotive oxygen sensor fittings, making the two automotive oxygen sensor fittings closely adhere to the grooves of the grooved roller, thus ensuring that the butting joints of the two automotive oxygen sensor fittings do not get misaligned. This precise positioning is crucial for the subsequent welding process, avoiding uneven or misaligned welding gaps between the two automotive oxygen sensor fittings, and improving the welding quality.

Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0025] Please refer to Figures 1 - 9 , one embodiment of the present invention is: an automobile oxygen sensor installation and welding device, including a processing table 1, a welding device 2 is arranged above the processing table 1, a continuous device 3 is arranged on the top of the processing table 1, and the continuous device 3 includes two fixing frames 31 fixed on the top of the processing table 1, a grooved roller 33 rotatably installed between the two fixing frames 31, and a servo motor 32 for driving the grooved roller 33 to rotate. A welding positioning line is provided in the middle of the outer wall of the grooved roller 33, and a plurality of grooves are provided outside the grooved roller 33 (in combinationFigure 4 and Figure 8 ), on one side of several grooves of the groove roller 33, turntables 34 are rotatably installed, and on the other side of several grooves of the groove roller 33, fixed disks 313 are fixed. A threaded ring 36 is fixed on the outer wall of a single turntable 34, a screw rod 35 is threadedly connected inside the threaded ring 36, connecting columns 37 are fixed in the middle of the outer walls of several other turntables 34, clamping plates one 38 are fixed on the end faces of the screw rod 35 and several connecting columns 37, a sliding column 312 is penetrated and slidably installed on the outer wall of the fixed disk 313, and an I-shaped disk 314 (as Figure 5 shown) is fixed outside the sliding column 312, and a spring is arranged between the I-shaped disk 314 and the fixed disk 313. A clamping plate two 311 is fixed on the end face of the sliding column 312. A driving assembly 39 is arranged on the side of the groove roller 33. The driving assembly 39 includes a driving motor 391, a large friction ring 394, and several small friction rings 392. The driving motor 391 is embedded at an eccentric position on the side of the groove roller 33, a friction disk 393 is fixed at the output end of the driving motor 391, the large friction ring 394 is rotatably installed on the outer wall of the groove roller 33, several small friction rings 392 are respectively fixed on one side of several turntables 34 away from the clamping plate one 38, the outer wall of the friction disk 393 is in contact with the inner wall of the large friction ring 394, and the outer wall of the large friction ring 394 is in contact with the outer walls of the small friction rings 392. A connecting ring 310 is arranged on one side of the clamping plate one 38 close to the turntable 34, and the connecting ring 310 is rotatably connected with several clamping plates one 38. A sliding groove for the connecting ring 310 to slide is opened inside the groove roller 33 (as Figure 6 shown). The clamping plate one 38 and the clamping plate two 311 are arranged oppositely. Through the setting of the above structure, the circular welding of two automotive oxygen sensor accessories is realized. And when the previous group of automotive oxygen sensor accessories is being welded, the staff can place the next group of automotive oxygen sensor accessories in other grooves of the groove roller 33, so as to realize the continuous welding operation of the automotive oxygen sensor accessories; at the same time, the staff can observe whether the welding positioning line opened in the middle of the groove roller 33 corresponds to the welding gap of the two automotive oxygen sensor accessories. When the welding positioning line does not correspond to the welding gap of the two automotive oxygen sensor accessories, through the setting of the above structure, the threaded ring 36 and the screw rod 35 are used to control the positions of the two automotive oxygen sensor accessories between the clamping plate two 311 and the clamping plate one 38, so as to ensure that the welding positioning line opened in the middle of the groove roller 33 corresponds to the welding gap of the two automotive oxygen sensor accessories, thereby avoiding welding defects or errors caused by incorrect positions of the automotive oxygen sensor accessories, and improving the welding quality.

[0026] A pushing device 4 is arranged at the groove roller 33. The pushing device 4 includes an L-shaped sliding plate 41, an L-shaped pushing plate 43, and a convex ring 44. A plurality of square holes are evenly opened in the circumferential direction on the outer wall of the groove roller 33 (as Figure 4 and Figure 8As shown in the figure, a through hole is provided in the middle of the groove of the groove roller 33, and the through hole of the groove roller 33 is communicated with the inside of the square hole. The L-shaped slide plate 41 is slidably installed inside the square hole of the groove roller 33, and a spring is provided between the L-shaped slide plate 41 and the outer wall of the groove roller 33. The L-shaped push plate 43 is slidably installed inside the through hole of the groove roller 33. The L-shaped slide plate 41 and the L-shaped push plate 43 are hinged and connected by a hinge rod 42. The convex ring 44 is fixed to the outer wall of the fixed frame 31 on one side by a bracket. A spherical ball is fixed to the side of the L-shaped slide plate 41 away from the L-shaped push plate 43. An arc-shaped protrusion is fixed to the lower rear side of the convex ring 44. The arc-shaped protrusion of the convex ring 44 is located on the movement track of the spherical ball of the L-shaped slide plate 41. Through the setting of the above structure, the L-shaped push plate 43 pushes the welded automobile oxygen sensor fitting out between the chuck two 311 and the chuck one 38, thus greatly reducing the time of manual operation. Workers no longer need to manually move or handle the welded fittings, improving the production efficiency and indirectly enhancing the working efficiency of workers.

[0027] The pushing device 4 further includes a U-shaped slide bar 45, a Y-shaped rod 46, and a slot plate 47. The U-shaped slide bar 45 is slidably installed on the inner wall of the groove of the groove roller 33. The Y-shaped rod 46 is fixed to the side of the U-shaped slide bar 45 close to the center of the groove roller 33, and the Y-shaped rod 46 is arranged inside the I-shaped plate 314. The slot plate 47 is fixed to the side of the L-shaped slide plate 41 close to the L-shaped push plate 43. A plurality of slots are provided at the top of the slot plate 47. The Y-shaped rod 46 is inserted into a single slot of the slot plate 47. A sliding groove for the Y-shaped rod 46 to slide is provided on the inner wall of the groove of the groove roller 33. Through the setting of the above structure, the L-shaped slide plate 41 pushes the slot plate 47 to drive the Y-shaped rod 46 to move. The Y-shaped rod 46 pushes the I-shaped plate 314 and the sliding column 312 to drive the chuck two 311 to no longer clamp the automobile oxygen sensor fitting, thus facilitating the pushing out of the welded automobile oxygen sensor fitting. At the same time, it effectively prevents the automobile oxygen sensor fitting from being worn due to friction during the pushing process. Because when directly pushing the automobile oxygen sensor fitting, if the chuck one 38 and the chuck two 311 still clamp the automobile oxygen sensor fitting, it is easy to cause too much friction and easily lead to wear and deformation of the automobile oxygen sensor fitting; at the same time, when the Y-shaped rod 46 is inserted into the slot of the slot plate 47, the stability of the clamping force of the chuck two 311 on the automobile oxygen sensor fitting can be effectively maintained.

[0028] During use, when the staff pulls the U-shaped slide bar 45 upward, the U-shaped slide bar 45 will drive the Y-shaped rod 46 out of the slot of the slot plate 47. At this time, the slide column 312 can displace. The staff pulls the slide column 312, and the slide column 312 drives the I-shaped disk 314 and the second clamping disk 311 away from the center of the groove roller 33. Place the two automotive oxygen sensor fittings to be welded into the groove of the groove roller 33. Release the slide column 312. Under the action of the spring force corresponding to the I-shaped disk 314, the I-shaped disk 314 drives the second clamping disk 311 to reset through the slide column 312. At this time, the two automotive oxygen sensor fittings are clamped and fixed between the second clamping disk 311 and the first clamping disk 38. Start the servo motor 32. The servo motor 32 drives the groove of the groove roller 33 with the automotive oxygen sensor fittings to rotate to the position below the welding device 2. Start the welding device 2. The welding device 2 will weld the two automotive oxygen sensor fittings. And while the welding device 2 is running, start the drive motor 391. The output end of the drive motor 391 drives the friction disk 393 to rotate. Under the action of the frictional force between the friction disk 393 and the large friction ring 394, the friction disk 393 drives the large friction ring 394 to rotate. Under the action of the frictional force between the large friction ring 394 and the small friction ring 392, the large friction ring 394 drives the small friction ring 392 to rotate. The small friction ring 392 drives a number of first clamping disks 38 to rotate within the groove of the groove roller 33 through the screw 35 and a number of connecting columns 37, so that the first clamping disk 38 and the second clamping disk 311 drive the clamped automotive oxygen sensor fittings to rotate, thus realizing the circular welding of the two automotive oxygen sensor fittings. And when the previous group of automotive oxygen sensor fittings are being welded, the staff can place the next group of automotive oxygen sensor fittings in other grooves of the groove roller 33, so as to realize the continuous welding operation of the automotive oxygen sensor fittings.

[0029] It should be noted that when two automotive oxygen sensor accessories are clamped and fixed between chuck two 311 and chuck one 38, the staff can observe whether the welding positioning line opened in the middle of the groove roller 33 corresponds to the welding gap of the two automotive oxygen sensor accessories. When the welding positioning line does not correspond to the welding gap of the two automotive oxygen sensor accessories, rotate the screw 35. The screw 35 is affected by the thread of the thread ring 36, and the thread ring 36 controls the screw 35 to drive chuck one 38 to move away from or close to the turntable 34, so as to control the position of the two automotive oxygen sensor accessories between chuck two 311 and chuck one 38, so as to ensure that the welding positioning line opened in the middle of the groove roller 33 corresponds to the welding gap of the two automotive oxygen sensor accessories, and thus avoid welding defects or errors caused by incorrect positions of the automotive oxygen sensor accessories, thereby improving the welding quality. When the chuck one 38 corresponding to the screw 35 undergoes displacement, the chuck one 38 corresponding to the screw 35 will drive other chuck ones 38 to move along through the connecting ring 310. And since the chuck one 38 is rotatably installed on the connecting ring 310, the connecting ring 310 will not interfere with the rotation of the chuck one 38.

[0030] When the groove roller 33 rotates, the groove roller 33 will drive the L-shaped slide plate 41 to rotate. When the ball of the L-shaped slide plate 41 moves to the arc protrusion position of the protrusion ring 44, the arc protrusion of the protrusion ring 44 pushes the ball of the L-shaped slide plate 41 to drive the L-shaped slide plate 41 to move towards the turntable 34. The spring corresponding to the L-shaped slide plate 41 is compressed, and the L-shaped slide plate 41 pushes the articulated rod 42 to drive the L-shaped push plate 43 to move along the inner wall of the through port of the groove roller 33 in a direction away from the center of the groove roller 33, so that the L-shaped push plate 43 pushes the welded automotive oxygen sensor accessories out between chuck two 311 and chuck one 38, thus greatly reducing the time of manual operation. Workers no longer need to manually move or handle the welded accessories, improving the production efficiency, and thus indirectly enhancing the work efficiency of the workers. At the same time, during the movement of the L-shaped slide plate 41, it will also push the slot plate 47 to move along. The slot plate 47 drives the Y-shaped rod 46 to move along. The Y-shaped rod 46 pushes the I-shaped plate 314 to drive the sliding column 312 to move in a direction away from the center of the groove roller 33, so that the sliding column 312 no longer drives chuck two 311 to clamp the automotive oxygen sensor accessories, which is conducive to the pushing out of the welded automotive oxygen sensor accessories, and effectively prevents the automotive oxygen sensor accessories from being worn due to friction during the pushing process. Because when directly pushing the automotive oxygen sensor accessories, if chuck one 38 and chuck two 311 still clamp the automotive oxygen sensor accessories, it is easy to cause excessive friction and easy to lead to wear and deformation of the automotive oxygen sensor accessories.

[0031] It should be noted that when the Y-shaped rod 46 is inserted into the slot of the slot plate 47, it can effectively maintain the stability of the clamping force of chuck two 311 on the automotive oxygen sensor accessories.

[0032] Please refer toFigures 1 - 9 , on the basis of the above embodiments, in another embodiment of the present invention, an anti-displacement device 5 is provided at the groove roller 33. The anti-displacement device 5 includes a plurality of connecting plates 51, a plurality of square rods 52, a plurality of inclined blocks 54, a plurality of long columns 55, two track groove rings 56, and a plurality of round blocks 57. The two track groove rings 56 are respectively fixed on both sides of the top of the processing table 1. An annular track groove is provided on the side of the two track groove rings 56 close to each other, and the upper side of the front side of the annular track groove is provided with a U-shaped inclined groove. A plurality of rectangular grooves are evenly arranged on the outer circumference of the outer wall of the groove roller 33. A plurality of inclined blocks 54 are respectively slidably installed inside the rectangular grooves of the groove roller 33. A plurality of long columns 55 are respectively fixed on the sides of adjacent two inclined blocks 54 away from each other. A plurality of square rods 52 are evenly fixed on the outer walls on both sides of the groove roller 33 in a circumferential manner. A plurality of connecting plates 51 are respectively slidably installed outside the plurality of square rods 52. Hinged connecting rods 53 are hinged on both sides of the connecting plate 51.

Four of the plurality of inclined blocks 54 are in a group, and the inclined surfaces of the four inclined blocks 54 are all arranged towards the groove direction of the groove roller 33. Through the setting of the above structure, the four inclined blocks 54 apply a thrust to the two automotive oxygen sensor fittings, so that the two automotive oxygen sensor fittings are closely attached to the groove of the groove roller 33, thereby ensuring that the butting parts of the two automotive oxygen sensor fittings will not be displaced. This precise positioning is crucial for the subsequent welding process, avoiding uneven or displaced welding seams of the two automotive oxygen sensor fittings, and thus improving the welding quality.

[0033] During use, after the two automotive oxygen sensor fittings are clamped and fixed between the second chuck 311 and the first chuck 38, when the groove roller 33 rotates, it will drive the connecting plate 51 and the round block 57 to rotate through the square rod 52. When the round block 57 moves to the U-shaped inclined groove position of the track groove ring 56, the U-shaped inclined groove of the track groove ring 56 will guide the round block 57 to drive the connecting plate 51 to move along the outer wall of the square rod 52 in a direction away from the center of the groove roller 33. The connecting plate 51 pulls one end of the hinged connecting rod 53 to move together. The other end of the hinged connecting rod 53 drives the inclined block 54 to move along the rectangular groove of the groove roller 33 towards the direction of the automotive oxygen sensor fitting through the long column 55, so that the four inclined blocks 54 apply a thrust to the two automotive oxygen sensor fittings, so that the two automotive oxygen sensor fittings are closely attached to the groove of the groove roller 33, thereby ensuring that the butting parts of the two automotive oxygen sensor fittings will not be displaced. This precise positioning is crucial for the subsequent welding process, avoiding uneven or displaced welding seams of the two automotive oxygen sensor fittings, and thus improving the welding quality.
