Description

Technical Field

[0001] This invention relates to the field of fuel tank processing technology, specifically to an integrated marking and welding equipment. Background Technology

[0002] To mark product information and batch numbers, laser marking machines are typically used to mark the surface of the fuel tank shell. Furthermore, to subsequently install brackets or pipe clamps on the surface of the fuel tank shell, studs need to be welded. Currently, stud welding is mostly used to weld these components at predetermined positions on the fuel tank shell. However, because the fuel tank shell is an irregularly shaped curved shell with a large volume and many convex contours, traditional fixed laser marking mechanisms and fixed stud welding equipment severely interfere with the handling of the workpiece, making it difficult to remove and place the fuel tank shell, and easily scratching the surface of the fuel tank shell. Moreover, during the fuel tank processing, laser marking and stud welding are usually performed separately, requiring two separate positioning operations, resulting in large positioning errors and low production efficiency. Summary of the Invention

[0003] In view of this, the present invention provides an integrated marking and welding equipment to solve the problems that, due to the irregular curved surface shell of the oil tank, traditional fixed laser marking mechanisms and fixed stud welding equipment will seriously interfere with the handling of workpieces. Furthermore, during the processing of the oil tank, the laser marking equipment and stud welding equipment are set up separately, requiring two positioning operations, which leads to large positioning errors and low production efficiency.

A manganese steel spring is provided between the holster and the head of the welding torch, and the locking bolts are adapted to indirectly abut against the head through the manganese steel spring.

[0014] In one alternative embodiment, the holster is provided with a gas interface adapted to be connected to a gas supply pipe for supplying protective gas into the holster.

[0015] In one optional embodiment, a limiting protrusion is fixedly connected to the upper end of the support base, and a limiting recess that cooperates with the limiting protrusion is fixedly connected to the flip arm.

[0016] In one optional embodiment, the first driving mechanism includes a horizontal guide rail and a first cylinder. A slider is slidably disposed on the horizontal guide rail and is fixedly connected to the laser marking device. The cylinder body of the first cylinder is connected to the horizontal guide rail, and the piston rod of the first cylinder is connected to the slider to drive the slider to slide in the horizontal direction.

[0017] In one alternative implementation, buffers are provided at both ends of the horizontal guide rail corresponding to the slider's movement path, and the pistons of the buffers are adapted to abut against the slider.

[0018] In one optional embodiment, the first driving mechanism further includes a column fixedly connected to the base, a sliding seat slidably disposed on the side of the column, the sliding seat being fixedly connected to a horizontal guide rail, and a threaded rod vertically disposed inside the column, the threaded rod being threadedly engaged with the sliding seat, suitable for driving the sliding seat to move up and down along the column by rotating the threaded rod.

[0019] The technical solution of this invention has the following advantages:

[0020] 1.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0039] The following is combined with Figures 1 to 7 The following describes embodiments of the present invention.

[0040] According to an embodiment of the present invention, an integrated marking and welding device is provided for marking and welding studs on an oil tank housing 8. The integrated marking and welding device includes:

[0041] A base 1, on which a housing fixing structure 2 is provided, the housing fixing structure 2 is used to position and fix the oil tank housing 8;

[0042] Laser marking device 3 is used to mark the oil tank shell 8;

[0043] The first driving mechanism 4 is mounted on the base 1. The first driving mechanism 4 is connected to the laser marking device 3 and is used to drive the laser marking device 3 to move. The laser marking device 3 has a marking station located above the oil tank housing 8 and a marking avoidance station whose projection along the direction of gravity avoids the oil tank housing 8.

[0044] Stud welding device 5, used for stud welding of oil tank shell 8;

[0045] The second drive mechanism 6 is mounted on the base 1 and is connected to the stud welding device 5. The second drive mechanism 6 is used to drive the stud welding device 5 to move. The stud welding device 5 has a welding station located above the oil tank housing 8 and a welding avoidance station whose projection along the direction of gravity avoids the oil tank housing 8.

[0046] The integrated marking and welding equipment provided in this embodiment uses a first driving mechanism 4 to switch the laser marking device between a marking station and an avoidance station, and a second driving mechanism to switch the stud welding device between a welding station and an avoidance station. This avoids interference with the handling of the fuel tank housing 8 and prevents scratches on the surface of the fuel tank housing 8 during handling. Furthermore, by integrating laser marking and stud welding functions into the base, only one positioning is required, reducing errors caused by two positioning operations and minimizing transfer steps, thus improving production efficiency.

[0047] Specifically, the base 1 includes a horizontally arranged flat plate, and a cabinet is arranged below the flat plate. The cabinet contains a control cabinet and a power supply.

[0048] The upper end face of the base 1 is fixedly connected to the housing fixing structure 2. The housing fixing structure 2 is used to position and fix the oil tank housing 8 to be processed, so that it does not shift during stud welding and marking, thereby ensuring processing accuracy and improving product consistency.

[0049] The housing fixing structure 2 includes multiple positioning mechanisms 21 and multiple clamping mechanisms 22. Each positioning mechanism 21 includes multiple vertically arranged fixing rods 211, spaced apart from the welded flange faces 81 of the tank housing 8. Each fixing rod 211 has a vertically arranged positioning pin 212 fixedly connected to its upper end. The upper end face of the fixing rod 211 is adapted to abut against the welded flange face 81, and the positioning pin 212 is adapted to be inserted into a positioning hole opened on the welded flange face 81 to restrict the horizontal movement of the tank housing 8. The clamping mechanisms 22 are used to press and fix the tank housing 8 after positioning is completed.

[0050] The clamping mechanism 22 includes a fixed frame 221, a third cylinder 222, and a pressure rod 223. The fixed frame 221 is provided with a support surface for abutting against the lower surface of the welding flange surface 81. The support surface is coplanar with the upper end surface of the fixed rod 211. The cylinder body of the third cylinder 222 is fixedly connected to the fixed frame 221, and the piston rod of the third cylinder 222 is vertically arranged. One end of the pressure rod 223 is rotatably connected to the piston rod of the third cylinder 222. The pressure rod 223 is adapted to rotate around the axis of the piston rod of the third cylinder 222 and has a pressing state in which the other end is located above the support surface, and a pressing avoidance state in which the projection of the other end along the direction of gravity avoids the support surface. The pressure rod 223 can move up and down under the drive of the piston rod of the third cylinder 222. Before placing the tank housing 8, adjust the pressure rod 223 to the pressing and avoiding state. Drive the pressure rod 223 of the third cylinder 222 upward to move away from the support surface so that the tank housing 8 can be placed on the housing fixing structure 2 from top to bottom, so that the positioning pin 212 is inserted into the positioning hole and the welding flange surface 81 abuts against the support surface and the upper end face of the fixing rod 211. After the tank housing 8 is placed in place, adjust the pressure rod 223 to the pressing state. Drive the pressure rod 223 of the third cylinder 222 downward to press the upper surface of the welding flange surface 81 to restrict the movement of the tank housing 8 in the vertical direction.

[0051] The laser marking device 3 is used to print markings such as model number, batch number, and serial number on the surface of the fuel tank housing 8, and has a marking station and a marking avoidance station. When the laser marking device 3 is in the marking station, its laser emission end is located directly above the preset marking area of ​​the fuel tank housing 8 to facilitate the laser marking operation; when the laser marking device 3 is in the marking avoidance station, its projection along the direction of gravity completely avoids the overall outline of the fuel tank housing 8 to avoid interference and collision with it when the fuel tank housing 8 is picked up or placed.

[0052] The first driving mechanism 4 is located on the upper surface of the base 1 and is connected to the laser marking device 3. It is used to drive the laser marking device 3 to move along a preset path, thereby switching between the marking station and the marking avoidance station.

[0053] The stud welding device 5 is used to weld and fix studs to the preset installation points of the fuel tank housing 8, and has a welding station and a welding avoidance station. When the stud welding device 5 is in the welding station, at least a part of its area is located above the fuel tank housing 8, and the welding head of the stud welding device 5 is in contact with the preset welding area of ​​the fuel tank housing 8; when the stud welding device 5 is in the welding avoidance station, its projection along the direction of gravity completely avoids the contour of the fuel tank housing 8, so as to avoid interference and collision with it when the fuel tank housing 8 is picked up or put down.

[0054] The second drive mechanism 6 is located on the upper surface of the base 1 and is connected to the stud welding device 5. It is used to drive the stud welding device 5 to move along a preset path, thereby switching between the welding station and the welding avoidance station.

[0055] In one embodiment, combined Figure 3 As shown, the second drive mechanism 6 includes a support base 61, a tilting arm 63, and a second cylinder 62. The support base 61 is fixedly connected to the base 1. The upper end of the support base 61 is hinged to the tilting arm 63 through a connecting frame 64. The cylinder body of the second cylinder 62 is fixedly connected to the base 1. The piston rod of the second cylinder 62 is hinged to one end of the tilting arm 63 to drive the tilting arm 63 to tilt around the support base 61. The other end of the tilting arm 63 is fixedly connected to the stud welding device 5 through a bending rod 67.

[0056] The marking and welding integrated equipment provided in this embodiment has a second cylinder 62 that drives the tilting arm 63 to tilt around the support base 61, so as to switch the stud welding device 5 between the welding station and the welding avoidance station. The tilting arm 63 is connected to the stud welding device 5 through the bending rod 67, so as to avoid the convex contour on the oil tank housing 8 through the bending rod 67.

[0057] Specifically, the support base 61 is vertically arranged and fixedly connected to the upper surface of the base 1, serving as the support foundation for the tilting arm 63. The upper end of the support base 61 is hinged to one end of the connecting frame 64, and the other end of the connecting frame 64 is hinged to the middle of the tilting arm 63, so that the tilting arm 63 can tilt around the top of the support base 61. The second cylinder 62 is vertically arranged, and the cylinder body of the second cylinder 62 is fixedly connected to the base 1. The piston rod of the second cylinder 62 is hinged to one end of the tilting arm 63. Through the extension and retraction of the piston rod, the tilting arm 63 is driven to tilt around the support base 61, thereby driving the stud welding device 5 to switch between the welding station and the welding avoidance station.

[0058] The other end of the tilting arm 63 away from the second cylinder 62 is fixedly connected to a bent rod 67, so as to be fixedly connected to the stud welding device 5 through the bent rod 67. The bent rod 67 avoids the convex contour on the oil tank housing 8 through its bending structure, so as to avoid interference with the convex contour during welding.

[0059] There are multiple second drive mechanisms 6, and each second drive mechanism 6 is connected to a stud welding device 5.

[0060] In one embodiment, combined Figure 6 As shown, there are multiple second drive mechanisms 6, and at least one bending rod 67 includes a first segment 671, a second segment 672 and a third segment 673 connected in sequence. The first segment 671 and the second segment 672 are arranged perpendicularly, and the second segment 672 and the third segment 673 are arranged at an angle.

[0061] Specifically, each tilting arm 63 is fixedly connected to the stud welding device 5 via a bent rod 67. When the stud welding device 5 is in the welding position, the bent rod 67 avoids the outward convex contour of the oil tank housing 8. As a feasible implementation, the first section 671 is fixedly connected to the tilting arm 63, and the third section 673 is fixedly connected to the stud welding device 5.

[0062] In one embodiment, combined Figure 2 As shown, the stud welding device 5 includes a welding torch 51, with a torch sleeve 52 fixedly connected to the head 511 of the welding torch 51, and a positioning seat 7 that is inserted into and cooperates with the torch sleeve 52 fixedly connected to the bent rod 67.

[0063] The marking and welding integrated equipment provided in this embodiment uses the cooperation between the gun sleeve 52 and the positioning seat 7 to facilitate the rapid positioning and installation of the welding gun 51. The gun sleeve 52 is designed to prevent spatter and weld slag adhesion during welding, and also serves as a positioning and installation device, which helps to ensure the concentricity of the position to be welded and the stud.

[0064] Specifically, the holster 52 is made of stainless steel. A positioning seat 7 is fixedly connected to the end of the bending rod 67. The positioning seat 7 has a through-hole that mates with the holster 52. The holster 52 can be stably inserted into the mounting hole of the positioning seat 7, which facilitates the quick positioning and connection of the holster 52 and the bending rod 67.

[0065] In one embodiment, combined Figure 7 As shown, the gun holster 52 has multiple threaded holes 521 spaced around its circumference. Locking bolts are connected to the internal threads of the threaded holes 521. A manganese steel spring 53 is provided between the gun holster 52 and the head 511 of the welding torch 51. The locking bolt is adapted to indirectly abut against the head 511 through the manganese steel spring 53.

[0066] The marking and welding integrated equipment provided in this embodiment improves the uniformity of force distribution and protects the head 511 of the welding torch 51 by setting manganese steel spring sheet 53.

[0067] Specifically, a gun sleeve 52 is detachably fixed to the outer periphery of the head 511 of the welding torch 51. A locking bolt is threaded inside the threaded hole 521 to lock and fix the gun sleeve 52 to the head of the welding torch 51.

[0068] The manganese steel spring 53 is annular, and a notch is provided on the annular manganese steel spring 53. This notch avoids the threaded hole 521. Since the head 511 of the welding torch 51 is a plastic part, by providing the manganese steel spring 53 between the torch sleeve 52 and the head 511, the locking bolt can indirectly abut against the head 511 through the manganese steel spring 53, thereby increasing the force-bearing area and the uniformity of force distribution, and better protecting the head 511.

[0069] In one embodiment, combined Figure 7As shown, the holster 52 is provided with a gas interface 54, which is adapted to be connected to a gas supply pipe for supplying protective gas into the holster 52.

[0070] Specifically, gas interface 54 is used to connect an external gas supply pipe. During welding, the external gas supply equipment delivers protective gas into the gun shroud 52 through the gas supply pipe and gas interface 54, improving the welding effect and the quality of the weld appearance, and eliminating the phenomenon of weld slag, black oxide layer, etc. on the surface.

[0071] In one embodiment, as shown in the figure, a limiting protrusion 65 is fixedly connected to the upper end of the support base 61, and a limiting recess 66 that cooperates with the limiting protrusion 65 is fixedly connected to the flip arm 63.

[0072] The marking and welding integrated equipment provided in this embodiment limits the flipping angle of the flipping arm 63 through the cooperation of the limiting protrusion 65 and the limiting concave block 66, ensuring the stability of the flipping arm 63 when the stud welding device 5 is in the welding position.

[0073] In one embodiment, combined Figures 1 to 2 As shown, the first driving mechanism 4 includes a horizontal guide rail 42 and a first cylinder 41. A slider 43 is slidably disposed on the horizontal guide rail 42. The slider 43 is fixedly connected to the laser marking device 3. The cylinder body of the first cylinder 41 is connected to the horizontal guide rail 42, and the piston rod of the first cylinder 41 is connected to the slider 43 to drive the slider 43 to slide in the horizontal direction.

[0074] The marking and welding integrated equipment provided in this embodiment uses a horizontal guide rail 42 to support the weight of the laser marking device 3 and guide its movement. The piston rod of the first cylinder 41 does not need to support the weight of the laser marking device 3, thereby improving the service life of the first cylinder 41 and reducing the failure rate.

[0075] Specifically, the slider 43 is slidably disposed on the upper end face of the horizontal guide rail 42, and the main body of the laser marking device 3 is fixedly connected to the upper end face of the slider 43. The first cylinder 41 is horizontally arranged on the side of the horizontal guide rail 42, the cylinder body of the first cylinder 41 is connected to the end of the horizontal guide rail 42, the piston rod of the first cylinder 41 is extended and retracted along the length direction of the horizontal guide rail 42, and the free end of the piston rod is connected to the slider 43. The piston rod of the first cylinder 41 is used to drive the laser marking device 3 to reciprocate between the marking station and the marking avoidance station in the horizontal direction through the slider 43.

[0076] The first cylinder 41 is a magnetic cylinder. Two magnetic switches 45 are spaced apart on the cylinder body along the direction of piston rod movement. The magnetic switches 45 are used to detect the piston position of the magnetic cylinder.

[0077] In one embodiment, combined Figure 5 and Figure 6As shown, buffers 44 are respectively provided at both ends of the horizontal guide rail 42 corresponding to the moving path of the slider 43, and the piston of the buffer 44 is adapted to abut against the slider 43.

[0078] Specifically, the buffer 44 is fixedly connected to the horizontal guide rail 42 via the connecting bracket 49. The buffer 44 is a hydraulic buffer or a spring buffer. The buffer 44 is used to flexibly limit the slider 43, which, compared to rigid limiting, can avoid rigid collisions, reduce noise, and protect the equipment.

[0079] In one embodiment, combined Figure 2 , Figure 3 and Figure 6 As shown, the first driving mechanism 4 also includes a column 46 fixedly connected to the base 1. A sliding seat 47 is slidably provided on the side of the column 46. The sliding seat 47 is fixedly connected to the horizontal guide rail 42. A threaded rod is vertically provided inside the column 46. The threaded rod is threadedly engaged with the sliding seat 47, which is suitable for driving the sliding seat 47 to move up and down along the column 46 by rotating the threaded rod.

[0080] The marking and welding integrated equipment provided in this embodiment can adjust the height of the laser marking device 3 by rotating the threaded rod to adapt to the height of the oil tank housing 8, thereby improving the versatility of the equipment.

[0081] Specifically, the column 46 is vertically positioned with an internal cavity. A threaded rod is vertically positioned and rotatably mounted within the cavity. A handwheel 48 is coaxially fixedly connected to the upper end of the threaded rod. The handwheel 48 is rotatably mounted on the top of the column 46. Rotating the handwheel 48 causes the threaded rod to rotate around its own axis. A horizontal guide rail 42 is fixedly connected to the upper surface of the sliding seat 47. A portion of the sliding seat 47 extends into the cavity and engages with the threaded rod, allowing it to move up and down along the column 46 as the threaded rod rotates. This adjusts the vertical height of the laser marking device 3, adapting to the marking needs of oil tank housings 8 of different heights and improving the equipment's versatility.

[0082] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope defined by the present invention.
