DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The purpose of the present invention is to provide a multi-angle automatic welding device for gas cylinders to solve the problems existing in the above-mentioned prior art, which can drive the multi-angle movement of the welding gun body, thereby realizing welding automation, reducing the labor intensity of the staff and improving work efficiency.

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] like Figure 2-Figure 10As shown, this embodiment provides a multi-angle automatic welding device for gas cylinders, including a frame body 1, the frame body 1 includes a frame bottom beam 101 and a frame vertical beam 102, the frame bottom beam 101 and the frame vertical beam 102 are vertically arranged, and the whole is L-shaped. A welding main arm lifting device 2 is provided on the frame vertical beam 102, and the welding main arm lifting device 2 includes a welding main arm 206, and the welding main arm 206 can move up and down along the frame vertical beam 102. A lateral coarse adjustment linear module 301 is installed on the welding main arm 206, and the lateral coarse adjustment linear module 301 can roughly adjust the lateral position of the welding gun body 4. The moving end of the lateral coarse adjustment linear module 301 is connected to the welding gun multi-angle fine adjustment device 3, and the welding gun multi-angle fine adjustment device 3 includes an electric rotating disk 303, and the electric rotating disk 303 is installed on the moving end of the lateral coarse adjustment linear module 301. The electric rotating disk 303 is a prior art, which can drive the welding gun body 4 to rotate along a certain angle. The movable end of the electric rotating disk 303 is connected to a transverse fine-tuning linear module 304, which is used to fine-tune the transverse position of the welding gun body 4. The movable end of the transverse fine-tuning linear module 304 is connected to a lifting fine-tuning linear module 305, and the movable end of the lifting fine-tuning linear module 305 is connected to the welding gun body 4, and the lifting fine-tuning linear module 305 is used to fine-tune the lifting (i.e., the vertical position) of the welding gun body 4. A gas cylinder angle adjustment device 5 is provided on the frame bottom beam 101, and the gas cylinder angle adjustment device 5 is used to adjust the angle between the gas cylinder component body 7 and the horizontal direction. The gas cylinder angle adjustment device 5 is connected to a gas cylinder rotation transmission device 6, and the gas cylinder rotation transmission device 6 is used to drive the gas cylinder component body 7 to rotate along its own axial direction. The gas cylinder rotation transmission device 6 is connected to a gas cylinder connector, and the gas cylinder connector is used to connect the gas cylinder component body 7.

[0036] It should be noted that the above-mentioned coarse adjustment linear module 301, fine adjustment linear module 304 and lifting fine adjustment linear module 305 are all existing linear module devices, which are existing mature devices. Here, a unified and brief description of the linear module structure is given, which includes a linear module motor, the output shaft of the linear module motor is connected to a linear module lead screw, and the linear module lead screw is threadedly connected to a linear module slider (the moving end of each linear module mentioned above is the linear module slider), and of course also includes a linear module housing, which is used to limit the linear module slider and protect the linear module lead screw and other structures. When the linear module motor is started, it can drive the linear module lead screw to rotate. Due to the limiting effect of the linear module housing, the linear module slider can only move linearly along the axial direction of the linear module lead screw, and will not rotate therewith. The structures of the transverse coarse adjustment linear module 301, the transverse fine adjustment linear module 304 and the lifting fine adjustment linear module 305 are basically the same, and the only difference is the size. The specific size is not limited here, and technical personnel in this field can choose the appropriate size and model according to actual needs.

[0037] In addition, a controller can be installed on the frame beam 102. The controller can be an existing control box, a PLC controller or a single-chip microcomputer controller. And the welding main arm lifting device 2, the lateral rough adjustment linear module 301, the electric rotating disk 303, the lateral fine adjustment linear module 304, the lifting fine adjustment linear module 305, the gas cylinder angle adjustment device 5 and the gas cylinder rotation transmission device 6 are all electrically connected to the controller to achieve unified control.

[0038] In actual use, the gas cylinder component body 7 is first installed on the gas cylinder connector, and the welding gun body 4 is installed on the moving end of the lifting fine adjustment linear module 305. Then the staff can adjust the position of the welding gun body 4 by controlling the welding main arm lifting device 2, the lateral coarse adjustment linear module 301, the electric rotating disk 303, the lateral fine adjustment linear module 304 and the lifting fine adjustment linear module 305 through the controller according to the position where the gas cylinder component body 7 needs to be welded, and adjust the position of the gas cylinder component body 7 by controlling the gas cylinder angle adjustment device 5 and the gas cylinder rotation transmission device 6, so that the welding gun body 4 reaches the position where welding is required for welding.

[0039] In this embodiment, if Figure 3 As shown, a lower cross beam 104 is provided on each side of the frame bottom beam 101, and two frame vertical beams 102 are provided. The upper ends of the two frame vertical beams 102 are connected to an upper cross beam 103, so that the two frame vertical beams 102 are connected as a whole. The upper cross beam 103 and the lower cross beam 104 are both square tube structures, and a blocking plate 107 is provided at both ends of the upper cross beam 103 and the lower cross beam 104 to enhance the overall strength of the upper cross beam 103 and the lower cross beam 104.

[0040] In addition, a frame angle steel 105 with an L-shaped cross section is installed on the side of the lower cross beam 104 away from the frame bottom beam 101. The frame angle steel 105 is provided to improve the overall stability. And each frame angle steel 105 is provided with a plurality of angle steel reinforcement ribs 106 to improve the support strength of the frame angle steel 105. In addition, the L-shaped frame angle steel 105 is provided with anchor bolt holes to facilitate the installation of the frame angle steel 105 on the construction site, which can improve the stability of the equipment.

[0041] In this embodiment, if Figure 4As shown, the welding main arm lifting device 2 also includes a lifting coarse adjustment motor 201, which is installed on the upper crossbeam 103, and the output shaft of the lifting coarse adjustment motor 201 passes through the upper crossbeam 103 and is arranged downward, and the output shaft of the lifting coarse adjustment motor 201 is connected to a lifting coarse adjustment screw rod 202 through a reducer, and the lifting coarse adjustment screw rod 202 is vertically arranged and located between the two frame vertical beams 102. A lifting coarse adjustment support seat 204 is also fixed between the two frame vertical beams 102, and a bearing seat is provided on the lifting coarse adjustment support seat 204, and the lower end of the lifting coarse adjustment screw rod 202 is rotatably connected to the bearing seat of the lifting coarse adjustment support seat 204. A lifting coarse adjustment movable seat 203 is threadedly connected to the lifting coarse adjustment screw rod 202, and the lifting coarse adjustment screw rod 202 can form a screw nut substructure with the lifting coarse adjustment movable seat 203. A lifting coarse adjustment sleeve 205 is fixed on both sides of the lifting coarse adjustment movable seat 203, and the two lifting coarse adjustment sleeves 205 are respectively slidably connected to the two frame vertical beams 102. The shape of the lifting coarse adjustment sleeve 205 matches the cross-sectional shape of the frame vertical beam 102, and both can be square tubes or round tubes.

[0042] When it is necessary to control the lifting and lowering of the welding main arm 206, it is only necessary to start the lifting and coarse adjustment motor 201. The output shaft of the lifting and coarse adjustment motor 201 drives the lifting and coarse adjustment screw 202 to rotate through a reducer. Because the lifting and coarse adjustment screw 202 is threadedly connected to the lifting and coarse adjustment movable seat 203, and because the lifting and coarse adjustment movable seat 203 is connected on both sides with a lifting and coarse adjustment sleeve 205 that can only slide up and down, the lifting and coarse adjustment movable seat 203 can only drive the lifting and coarse adjustment sleeve 205 and the welding main arm 206 to perform lifting and lowering movements as the lifting and coarse adjustment screw 202 rotates.

[0043] In this embodiment, if Figure 5 As shown, one end of the welding main arm 206 is fixed to one of the frame beams 102, and a first reinforcing tube 207 is connected between the frame beam 102 to which the welding main arm 206 is fixed and the welding main arm 206, and a second reinforcing tube 208 is connected between the other frame beam 102 and the welding main arm 206. In addition, for some welding gun bodies 4 that require welding wire, a wire feeding mechanism is indispensable. The wire feeding mechanism is a prior art, and its specific structure is not described in detail here. Figure 2 The wire feeding mechanism can be installed at the upper end of the welding main arm 206 , and the first reinforcing tube 207 and the second reinforcing tube 208 are used to improve the stability of the welding main arm 206 .

[0044] In this embodiment, if Figure 6As shown, the movable end of the transverse coarse adjustment linear module 301 (i.e., the linear module slider in the transverse coarse adjustment linear module 301) is connected to the transverse connecting plate 302, the transverse connecting plate 302 is vertically arranged, the fixed surface of the electric rotating disk 303 is installed on the transverse connecting plate 302, the rotating surface of the electric rotating disk 303 is connected to the back of the linear module shell of the transverse fine adjustment linear module 304, and the back of the linear module shell of the lifting fine adjustment linear module 305 is fixedly connected to the linear module slider in the transverse fine adjustment linear module 304.

[0045] A T-shaped piece 306 is fixed on the moving end (i.e., the linear module slider) of the lifting and fine-tuning linear module 305. The T-shaped piece 306 includes a fixed connecting plate and a fixed cylinder. The fixed connecting plate is fixed on the moving end of the lifting and fine-tuning linear module 305, and one end of the fixed cylinder is fixed on the fixed connecting plate. The other end of the fixed cylinder is connected to an upper clamp 307, and the upper clamp 307 also clamps an extension rod 308, through which the distance from the welding gun body 4 to the lifting and fine-tuning linear module 305 can be extended. The end of the extension rod 308 away from the upper clamp 307 is connected to a lower clamp 309, and the lower clamp 309 also clamps the welding gun body 4. The upper clamp 307 and the lower clamp 309 have the same structure, and both have two clips connected together by bolts.

[0046] In this embodiment, a camera is provided on the lower fixture 309, and the camera is also electrically connected to the display screen on the controller for real-time monitoring of the welding situation. At the same time, a wire guide tube is also installed on the lower fixture 309 to guide the welding wire.

[0047] In this embodiment, if Figure 7 As shown, the gas cylinder angle adjustment device 5 includes an angle adjustment cylinder 501, an angle adjustment support shaft 502, a support sleeve 503, a ratchet plate 504 and a self-locking positioning device 505. Among them, the angle adjustment cylinder 501 is an existing three-stage telescopic cylinder, one end of the angle adjustment cylinder 501 is hinged on the frame bottom beam 101, and the other end of the angle adjustment cylinder 501 is hinged on the support sleeve 503, and one end of the support sleeve 503 (the lower end in the figure) is fixedly connected to one end of the angle adjustment support shaft 502 (the upper end in the figure). The ratchet plate 504 is fixed on the frame bottom beam 101, and a plurality of ratchets are provided on the ratchet plate 504. The end of the angle adjustment support shaft 502 away from the support sleeve 503 is hinged to the side of the ratchet plate 504 through a pin. One end of the self-locking positioning device 505 is fixed on the outer wall of the angle adjustment support shaft 502. The self-locking positioning device 505 includes a self-locking cylinder and a self-locking pawl. The self-locking pawl is fixed on the telescopic end of the self-locking cylinder, and when the self-locking pawl is extended, it can extend into the gap between two adjacent ratchet teeth.

[0048] In actual use, the controller can adjust the angle between the support sleeve 503 and the angle adjustment support shaft 502 and the horizontal direction by controlling the extension and contraction of the angle adjustment cylinder 501. Specifically, when the angle adjustment cylinder 501 is extended, the self-locking cylinder drives the self-locking pawl to be in an extended state, and the angle adjustment cylinder 501 drives the support sleeve 503 to rise continuously. At the same time, the self-locking pawl on the angle adjustment support shaft 502 will also move upward along multiple ratchets. During this period, the self-locking pawl can have a self-locking effect on the support sleeve 503 and the angle adjustment support shaft 502, so that it can be stuck at any position. It should be noted that due to the special shape of the ratchet, the self-locking pawl can only move upward along each ratchet. If the self-locking pawl moves downward, it will be stuck by the ratchet below and cannot move downward. This is the same as the working principle of the existing ratchet pawl structure, so it will not be described in detail. When the support sleeve 503 and the angle adjustment support shaft 502 need to be lowered, it is necessary to first control the self-locking cylinder to retract the self-locking pawl so that the self-locking pawl and the ratchet are no longer in contact, and then control the angle adjustment cylinder 501 to retract. The angle adjustment cylinder 501 can then drive the support sleeve 503 and the angle adjustment support shaft 502 to rotate downward.

[0049] In this embodiment, if Figure 7-Figure 8 As shown, the gas cylinder rotation transmission device 6 includes a rotation drive motor 601, which is fixed on the outer wall of the support sleeve 503, and the output shaft of the rotation drive motor 601 is connected to the driving wheel through a reducer. A clamping member rotating shaft 604 is rotatably connected in the support sleeve 503, and a horn clamping member 603 is fixed to one end of the clamping member rotating shaft 604, and a driven wheel is installed on the outer side of one end of the horn clamping member 603 close to the clamping member rotating shaft 604, and the driving wheel and the driven wheel are connected through a transmission belt 602. The open end of the horn clamping member 603 is used to connect the gas cylinder connector.

[0050] In actual use, the controller is used to control the rotation drive motor 601 to start, and the rotation drive motor 601 drives the speaker clamp 603 to rotate through the driving wheel, the transmission belt 602 and the driven wheel, thereby driving the gas cylinder connector and the gas cylinder component body 7 to rotate.

[0051] In this embodiment, if Figure 8As shown, a rotating bearing 605 is connected to each end of the clamping member rotating shaft 604, and bearing grooves for mounting the rotating bearing 605 are provided on the inner sides of the two ends of the support sleeve 503, and the outer ring of the rotating bearing 605 is connected to the inner wall of the bearing groove of the support sleeve 503. Two retaining springs 606 are also provided on the clamping member rotating shaft 604, and the two retaining springs 606 are respectively provided on the side of the rotating bearing 605 close to the inside of the support sleeve 503, and the function of the retaining springs 606 is to limit the rotating bearing 605. A gasket 607 and a locking nut 608 are also connected to the side of the rotating bearing 605 located below and away from the retaining springs 606, and the function of the gasket 607 is to protect the rotating bearing 605, and the locking nut 608 is threadedly connected to the clamping member rotating shaft 604, and is used to limit the gasket 607, so that the gasket 607 always abuts against the rotating bearing 605 below.

[0052] In this embodiment, if Figure 9-10 As shown, the gas cylinder connector includes a clamping base 609 made of stainless steel, and six hinged joints 610 are evenly distributed in the circumferential direction of the clamping base 609. Each hinged joint 610 is connected to a clamping valve flap 611. There is a gap between two adjacent clamping valve flaps 611. All the clamping valve flaps 611 clamp a copper clamping tube 612 together, and the end of the gas cylinder component body 7 can be inserted into the clamping tube 612. In addition, an M22 external thread is provided at one end of the clamping base 609 away from the clamping tube 612, and correspondingly, an M22 internal thread is provided at the center of the horn clamp 603, so that the clamping base 609 and the horn clamp 603 can be threadedly connected.

[0053] When installing the gas cylinder connector, first insert the end of the gas cylinder component body 7 into the clamping tube 612, and then thread the clamping base 609 into the horn clamping piece 603. As the clamping base 609 is continuously tightened, the horn clamping piece 603 has a conical structure, so the horn clamping piece 603 applies an increasingly tight clamping force to each clamping valve flap 611, and the clamping valve flap 611 will apply an increasingly tight clamping force to the clamping tube 612. Finally, the clamping tube 612 firmly clamps the gas cylinder component body 7, thereby fixing the gas cylinder component body 7.

[0054] In addition, an anti-loosening pin hole is respectively provided on both sides of the horn clamp 603, and corresponding anti-loosening pin holes are provided on both sides of the gas cylinder component body 7. When the clamping tube 612 firmly clamps the gas cylinder component body 7, an anti-loosening pin can be used to pass through the anti-loosening pin holes on the horn clamp 603 and the gas cylinder component body 7 in turn, thereby achieving further fixation of the gas cylinder component body 7.

[0055] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
