Description

Technical Field

[0001] This invention relates to the field of welding, and in particular to a welding device for automotive parts with a positioning module. Background Technology

[0002] Welding of automotive parts is a core manufacturing process that ensures the structural strength, safety, and functional integrity of vehicles. Among them, tapered converging tubes and tapered expanding tubes are responsible for guiding and optimizing the flow of air, liquid, or exhaust gas in systems such as intake, exhaust, turbocharging, cooling, and air conditioning. The welding quality and welding efficiency of these tubes are of great significance to automotive processing.

[0003] The prior art CN202511430336 discloses a welding positioning device for pipelines in new energy vehicles. After welding is completed, the air pump delivers airflow through the rotary joint and the vent pipe to the inside of the pipeline, carrying away the residual heat at the weld. This can shorten the time spent welding the pipeline and improve the efficiency of the pipeline in the entire processing flow.

[0004] The prior art CN202510171227.0 discloses an automotive parts welding device, which enhances the clamping force on the raw materials of the parts by setting up an elastic clamping mechanism, a heat-deformation fixing component, and an induction component, thereby improving the stability and clamping accuracy of the fixed parts, and thus improving the welding accuracy and welding quality.

[0005] In the aforementioned prior art, the constraint and positioning of the parts to be welded are achieved through two relatively moving clamping structures, and welding can then be performed at the joint of the two pipes. However, in actual operation, segment-by-segment welding will lead to limited welding efficiency. To overcome this problem, multiple sliding clamping devices can be used to clamp multiple pipe segments. However, if the cross-sections and dimensions of the multiple pipe segments are different, such as a tapered converging pipe composed of thin pipes, thick pipes and tapered pipes, if the arrangement of the clamping devices is incorrect, the incorrect pipes need to be removed from the clamping devices one by one and readjusted, which results in a lot of time spent on preparation work before welding and affects welding efficiency. Summary of the Invention

[0006] The core of this invention lies in the use of a positioning adjustment component and a follow-up baffle to perform secondary positioning adjustments on incorrectly positioned pipes without disassembling and reinstalling them. After adjustment, multi-point simultaneous welding is performed to improve welding efficiency, solving the problem of limited welding efficiency in existing technologies due to excessive adjustment time and single-point welding. It also provides targeted constraint positioning operations for vertical welding to ensure welding level.

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A welding device for automotive parts with a positioning module includes a base plate with a groove on the top, a fixed baffle installed on one side of the top of the base plate, a slide rail installed on the top of the fixed baffle, an adjustment groove inside the slide rail, a strip groove on the inner top wall of the adjustment groove, symmetrically arranged side plates installed at the bottom of the slide rail, and lifting grooves on the surfaces of the two side plates that are close to each other. Multiple positioning adjustment components are slidably connected inside the adjustment groove. Each positioning adjustment component includes a positioning slider that is slidably connected in the adjustment groove. Each positioning slider has a cross-shaped insertion block installed at its bottom. Each positioning slider has a moving groove inside. Each moving groove has a magnetic block that matches the strip groove that is slidably connected inside. The inner wall of the moving groove is equipped with an adjustment unit for controlling the raising and lowering of the magnetic block. The bottom of the positioning slider is fixedly connected to a No. 1 plate. Each magnetic block has a linkage plate symmetrically installed at its bottom. The bottom of the No. 1 plate is connected to a shaft. The surface of the shaft is mounted on a No. 2 plate. The bottom of the No. 2 plate is fixedly connected to a hanging ring. Multiple small electric actuators are embedded inside the hanging ring. The power end of the small electric actuators is equipped with an elastic pad through a damping shaft. The bottom of the linkage plate is connected to a follow-up limiting unit for controlling the swing state of the No. 2 plate.

[0009] Furthermore, the follow-up limiting unit includes an arc-shaped plate fixedly connected to the bottom of the linkage plate and having the same diameter as the shaft member. An arc-shaped groove is provided inside the arc-shaped plate, and a follow-up slider is slidably connected inside the arc-shaped groove. A support rod is installed at the bottom of the follow-up slider, and a constraint frame with a C-shaped cross section is connected to the tail end of the support rod. The end of the constraint frame is in contact with the surface of the second plate.

[0010] Furthermore, the adjustment unit includes an electromagnetic block installed on the bottom wall of the moving slot, and the electromagnetic block and the magnetic block attract each other. The surface of the electromagnetic block is connected to a spring member whose tail end is connected to the magnetic block. The linkage plate is located between the first plate and the plug-in block, and the linkage plate slides through the interior of the electromagnetic block and the positioning slider.

[0011] Furthermore, a limit rod is installed on the surface of the second plate. When the support rod descends to the surface of the limit rod, the magnetic block moves to the lowest point, and at this time the center of the arc plate and the shaft are on the same axis.

[0012] Furthermore, the slide rail component has an internal long groove, and a support block is slidably connected inside the long groove. A drive motor is installed on one side of the top of the slide rail component, and a lead screw is connected to the output end of the drive motor. A movable block connected to the bottom of the lead screw is threadedly connected to the support block, and a follower baffle is connected to the bottom of the support block.

[0013] Furthermore, the plug-in block matches the support groove, and the cross-sectional width of the adjustment groove is greater than the maximum distance between the two plug-in blocks on the diagonal.

[0014] Furthermore, the top and bottom of the follow-up baffle are respectively provided with magnetic suction groove and groove, the support block slidably connected in the magnetic suction groove is made of permanent magnet, and the inside of the groove is slidably connected with a sliding block that is slidably connected to the groove.

[0015] Optionally, the inner wall of the magnetic block is provided with a through groove, and an electromagnet is installed in the middle of the inner wall of the through groove. Constraint springs are symmetrically installed on the surface of the electromagnet, and a magnetic rack is connected to the end of each constraint spring. The inner top wall of the adjustment groove is provided with a constraint groove, and the inner wall of the constraint groove is arranged with toothed conditions.

[0016] Furthermore, after the positioning slider is rotated 90 degrees, the magnetic block at the top is located on the left side of the constraint groove, and the cross-sectional width of the constraint groove is greater than the cross-sectional width of the magnetic block.

[0017] Compared with the prior art, the advantages of this invention are: (1) Through the coordinated design of the slide rail, positioning adjustment component and hanging ring, when the pipe diameter is the same, multiple sections of pipe to be welded can be constrained simultaneously and the follower baffle can be used to uniformly gather them to achieve abutment constraint, which assists in subsequent multi-point simultaneous welding; when there are different diameter pipes and the order of the different diameter pipes is wrong, the electromagnetic block attracts the magnetic block to descend, so that the follower limiting unit can assist the second plate to swing, and then adjust the pipe that originally interfered with the hanging ring in the strip groove to avoid it, so as to realize the movement adjustment of the pipe until the placement position is adjusted correctly, and the follower baffle is used to abutment constraint, waiting for multi-point simultaneous welding, without disassembly and reassembly, shortening the positioning adjustment time and improving welding efficiency.

[0018] (2) When performing vertical welding, this application uses a positioning slider to convert the pipe to be welded from a horizontal butt joint to a vertical corner joint state, so that after the positioning slider rotates 90 degrees, the magnetic block can move along the constraint groove and automatically lock and position during the movement using an electromagnet, a tooth condition and a magnetic rack, thus expanding the scope of application of this application.

[0021] The technical solutions will now be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention.

[0022] Example 1: Please see Figure 1 , Figure 2 and Figure 5 A welding device for automotive parts with a positioning module includes a base plate 1 with a groove on the top, a fixed baffle 2 installed on one side of the top of the base plate 1, a slide rail 4 installed on the top of the fixed baffle 2, an adjustment groove 44 inside the slide rail 4, a strip groove 43 on the inner top wall of the adjustment groove 44, symmetrically arranged side plates 41 installed at the bottom of the slide rail 4, and lifting grooves 42 on the surfaces of the two side plates 41 that are close to each other, and multiple positioning adjustment components 8 are slidably connected inside the adjustment groove 44. Please see Figures 2-4Each positioning adjustment component 8 includes a positioning slider 82 slidably connected in the adjustment groove 44. Each positioning slider 82 has a cross-shaped insertion block 9 installed at its bottom. The insertion block 9 matches the lifting groove 42. Each positioning slider 82 has a moving groove 823 inside. Each moving groove 823 has a magnetic block 81 slidably connected inside, which matches the strip groove 43. The inner wall of the moving groove 823 is equipped with an adjustment unit for controlling the lifting of the magnetic block 81. A first plate 83 is fixedly connected to the bottom of the positioning slider 82. A linkage plate 85 is symmetrically installed on the bottom of each magnetic block 81. A shaft member 12 is connected to the bottom of the first plate 83. A second plate 84 is installed on the surface of the shaft member 12. A hanging ring 6 is fixedly connected to the bottom of the second plate 84, and multiple small electric actuators 61 are embedded inside the hanging ring 6. An elastic pad (such as...) is installed at the power end of each small electric actuator 61 via a damping shaft. Figure 8 As shown), and the bottom of the linkage plate 85 is connected to a follow-up limiting unit for controlling the swing state of the second plate 84.

[0023] Please see Figures 3-4 The follow-up limiting unit includes an arc-shaped plate 86 fixedly connected to the bottom of the linkage plate 85 and having the same diameter as the shaft member 12. An arc-shaped groove is provided inside the arc-shaped plate 86, and a follow-up slider 88 is slidably connected inside the arc-shaped groove. A support rod 87 is installed at the bottom of the follow-up slider 88, and a constraint frame 89 with a C-shaped cross section is connected to the tail end of the support rod 87. The end of the constraint frame 89 is in contact with the surface of the second plate 84.

[0024] Please see Figure 3 The adjustment unit includes an electromagnetic block 821 installed on the bottom wall of the moving slot 823, and the electromagnetic block 821 and the magnetic block 81 attract each other. The surface of the electromagnetic block 821 is connected to a spring member 822 whose tail end is connected to the magnetic block 81. The linkage plate 85 is located between the first plate 83 and the plug block 9, and the linkage plate 85 slides through the interior of the electromagnetic block 821 and the positioning slider 82.

[0025] Specifically, during welding, if all the pipes to be welded are of equal diameter, a small electric actuator 61 can be used to constrain the surface of the pipes (the elastic pad can both enhance friction and prevent the power end from directly and rigidly contacting the pipe surface, causing wear). The number of pipes corresponds one-to-one with the number of hanging rings 6. Then, the follower baffle 3 is used to perform end constraint operations on multiple separately arranged pipes that are in a constrained state on the same straight line (e.g., Figure 7 (As shown in the image), finally, place a welding torch at each welding position and perform welding operations simultaneously.

[0026] If there are size differences between the pipes to be welded, for example, when it is necessary to weld a thicker pipe (hereinafter referred to as pipe a) and a thinner pipe (hereinafter referred to as pipe b), a section of tapered pipe (hereinafter referred to as pipe c, the diameter of the narrower end of pipe c is the same as that of pipe b, and the diameter of the thicker end is the same as that of pipe a) needs to be welded in the middle for transition. After pipes a, b and c are constrained and limited by hanging ring 6 and small electric actuator 61 respectively (when constraining pipe c, the elastic pad can be adjusted to the same state as the slope of the surface of pipe c by using the damping shaft, and then the small electric actuator 61 extends to constrain and limit), they are arranged in the order of aCB or BCA, and then the welding operation of equal diameter pipes can be performed.

[0027] If an error occurs in the discharge, this application provides an example of discharge in the order of abc, and all three pipes are constrained using small electric actuators 61. In this case, to achieve efficient pipe positioning adjustment: Please see Figure 6 and Figure 9 The operator can activate the electromagnetic block 821 in the positioning slider 82 corresponding to tube C, causing the corresponding magnetic block 81 to descend into the moving groove 823. As the magnetic block 81 descends, it drives the linkage plate 85 connected at the bottom to descend until the support rod 87 descends to the limit rod 11 and stops descending. At this time, the operator pulls the second plate 84 corresponding to tube C to the right (the side of the adjusting groove 44 away from the strip groove 43), causing the insertion block 9 on the surface of the positioning slider 82 that is inserted into the left support groove 42 to leave, until the insertion block 9 on the right surface of the positioning slider 82 is inserted into the right support groove 42 and the positioning slider 82 stops moving. Then, pull the second plate 84 to the right (the purpose of which is to avoid the hanging ring 6 and the small electric push rod 61 on the surface of the b tube when moving towards the a tube). At the same time, pull the hanging ring 6 to move towards the a tube and move the b tube along the strip groove 43 away from the a tube. This allows the c tube to move along the right support groove 42 to the middle of the b tube and the a tube. Then, push the positioning slider 82 corresponding to the c tube to the left, so that the insertion block 9 on the left surface of the c tube is re-inserted into the left support groove 42. At this time, close the electromagnetic block 821, so that the magnetic block 81 returns to the strip groove 43. As the magnetic block 81 is raised, the follow-up limiting unit is also raised synchronously, so that the constraint frame 89 that is in contact with the surface of the second plate 84 can cooperate with the follow-up slider 88 to play a rotation limit role for the second plate 84 and keep it in a vertical state. Finally, the follow-up baffle 3 is used to gather and constrain multiple pipes, and multiple welding processes are carried out simultaneously, reducing the time required for positioning and adjustment and improving the overall welding efficiency.

[0028] Please see Figure 4A limit rod 11 is installed on the surface of plate 84. When the support rod 87 descends to the surface of the limit rod 11, the magnetic block 81 moves to the lowest point, and at this time the center of the arc plate 86 and the shaft member 12 are on the same axis.

[0029] Specifically, in this application, the surface of the follower slider 88 in the arc groove is equipped with a protrusion with a cross-shaped cross section, and the inner wall of the arc groove is provided with an arc-shaped limiting groove that matches the protrusion, so as to prevent the follower slider 88 from leaving the arc groove.

[0030] When the arc plate 86 descends to the surface of the limiting rod 11, the support rod 87 descends synchronously. The arc plate 86 and the shaft member 12 are at the same height and have the same diameter. Therefore, when the second plate 84 swings at this time, it will not be blocked by the constraint frame 89.

[0031] Please see Figure 1 The slide rail 4 has an internal long groove, and a support block 10 is slidably connected inside the long groove. A drive motor 7 is installed on the top side of the slide rail 4, and a lead screw 5 is connected to the output end of the drive motor 7. A movable block connected to the bottom of the support block 10 is threaded on the surface of the lead screw 5. A follower baffle 3 is connected to the bottom of the support block 10.

[0032] Specifically, the drive motor 7 drives the lead screw 5 to rotate, which in turn causes the moving block to move the support block 10 and the follower baffle 3 connected to its bottom. This can cause multiple pipes constrained by the hanging ring 6 to gradually converge until the two ends of the spliced ​​pipe formed by the multiple pipes are respectively constrained by the surfaces of the fixed baffle 2 and the follower baffle 3. This, combined with the radial constraint of the small electric push rod 61 inside the hanging ring 6, achieves stable contact between the ends of the multiple pipes, so that multiple welding guns can be used for welding simultaneously, thereby improving welding efficiency.

[0033] Example 2: Please see Figure 11 The top and bottom of the follow-up baffle 3 are respectively provided with magnetic suction groove 31 and groove. The support block 10 slidably connected in the magnetic suction groove 31 is made of permanent magnet. The sliding block slidably connected to the groove is slidably connected to the groove. The cross-sectional width of the adjustment groove 44 is greater than the maximum distance between the two diagonal plug blocks 9.

[0034] Please see Figure 10 and Figure 12 The inner wall of the magnetic block 81 is provided with a through groove, and an electromagnet 14 is installed in the middle of the inner wall of the through groove. Constraint springs 16 are symmetrically installed on the surface of the electromagnet 14. The end of each constraint spring 16 is connected to a magnetic rack 15. The inner top wall of the adjustment groove 44 is provided with a constraint groove 45, and the inner wall of the constraint groove 45 is arranged with toothed conditions 13.

[0035] After the positioning slider 82 is rotated 90 degrees, the top magnetic block 81 is located on the left side of the constraint groove 45, and the cross-sectional width of the constraint groove 45 is greater than the cross-sectional width of the magnetic block 81.

[0036] Specifically, in Embodiment 1, the main focus is on welding the pipe ends. In actual welding processes, if vertical welding is required, the applicability of this application is limited. To improve this problem, this embodiment is adopted.

[0037] In this embodiment, the vertical projection of the constraint groove 45 is located on the side of the hanging ring 6 away from the strip groove 43. Thus, when another hanging ring 6 moves along the constraint groove 45 after rotating the pipe it constrains by 90 degrees, it will not interfere with the surface constrained by the hanging ring 6 in the strip groove 43.

[0038] In addition, in the embodiment, the electromagnet 14 and the magnetic rack 15 repel each other.

[0039] Please see Figure 13 When two pipes need to be welded vertically, the two pipes (hereinafter referred to as pipe d and pipe e) are first constrained and fixed by two hanging rings 6. Then, the electromagnetic block 821 corresponding to pipe e is activated and the positioning slider 82 is moved slightly to the right (so that the plug block 9 is disengaged from the support groove 42 on the left side, and so that the positioning slider 82 and the four plug blocks 9 arranged in a cross shape on its surface are not interfered with when rotating in the adjustment groove 44). After rotating 90 degrees, the originally coaxial pipes d and e are changed to a vertical arrangement. Then, the positioning slider 82 is moved to the right so that the insertion block 9 on the surface of the positioning slider 82 can be inserted into the right support groove 42. After the insertion block 9 is inserted into the support groove 42, the magnetic block 81 is located directly below the constraint groove 45. The electromagnetic block 821 is turned off so that the magnetic block 81 moves up and resets to the inside of the constraint groove 45. Then, the hanging ring 6 is pulled to drive the e-tube to move along the surface of the constraint groove 45 until the welding position. Then, the electromagnet 14 is activated, causing the magnetic rack 15 to move outward and engage with the tooth condition 13 on the inner wall of the constraint groove 45 to achieve positioning constraint, and wait for welding. The other horizontal welding is the same as the operation method in Example 1.

[0040] In addition, when adjusting the contact area of ​​the follower baffle 3 to avoid motion interference from the vertically arranged hanging ring 6, the sliding connection between the magnetic groove 31 and the support block 10 can be used.

[0041] The above description is merely a preferred embodiment of the present invention; it encompasses all the protection scope of the present invention. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in the present invention, based on the technical solutions and improved concepts of the present invention, should be covered within the protection scope of the present invention.
