Description

Technical Field

[0001] The present invention relates to the technical field of component welding, and particularly to a welding device that is easy to convert automotive components. Background Art

[0002] Automotive components, as the foundation of the automotive industry, require large-scale production, and components need to be welded during the production process;

[0003] The publication number of the Chinese invention patent is CN119772460A, which discloses "a general-purpose welding device for automotive component processing, relating to the technical field of component welding, including a base. A rotating column is rotatably connected to the top of the base, and a placement plate is fixedly connected to the top of the rotating column. Through the setting of the cleaning unit, after welding is completed, when the sliding rod contacts the mounting block, the sliding rod and the first rack stop moving, and the first gear rotates to drive the rotating shaft, the L-shaped rod, and the two cleaning brushes to rotate towards the welding head. When the electric telescopic rod drives the welding head to weld the parts, when the sliding rod moves away from the mounting block, the tension spring drives the first rack to move towards the bracket, and the movement of the first rack drives the first gear, the rotating shaft, the L-shaped rod, and the two cleaning brushes to rotate downward, so that the two cleaning brushes move away from the welding head, and the two cleaning brushes swing back and forth to clean the welding head";

[0004] The above patent also has the following defects: For example, the application cleans the welding head through the cleaning brush. However, when the cleaning brush is directly abutted and cleaned without cooling the welding head, it not only causes the cleaning brush to have thermal failure and lose the cleaning ability, but also there is a risk of scratching the welding head if the material of the cleaning brush is relatively hard.

[0005] Therefore, it is urgent to improve the above patent to solve the above existing problems. Summary of the Invention

[0013] Preferably, the cleaning structure further includes two guide rods fixed to the inner wall of the installation shell. The sliding seat is slidably installed on the two guide rods. A first return spring surrounding the outside of the guide rod is fixed between the sliding seat and the installation shell. A reciprocating chute adapted to the rolling shaft is arranged inside the rotating cylinder. The rolling shaft drives the rotation of the rotating cylinder along one end of the reciprocating chute through the displacement of the sliding seat.

[0014] Preferably, the knocking part is composed of a sleeve and an elastic knocking block. The sleeve is fixed on one side of the sliding seat away from the first return spring. The elastic knocking block is slidably arranged inside the sleeve, and one end of the elastic knocking block extends out of the installation shell. A rolling shaft rotatably installed inside the sliding seat and in rolling cooperation with the rotating cylinder is arranged inside the sliding seat.

[0015] Preferably, the rotating cylinder is rotatably installed inside the installation shell. A stirring shaft extending into the installation shell and fixed to one end of the rotating cylinder is rotatably installed inside the liquid storage tank. A support frame is fixed to one side of the installation shell close to the welding pipe by bolts. The cleaning brush is slidably arranged inside the support frame. A dial block in abutting cooperation with the cleaning brush is fixed on the outer surface of the sleeve.

[0016] Preferably, the infusion structure includes an infusion member and a nozzle fixed to the upper surface of the support frame. The infusion member includes a piston cylinder fixed to the inner bottom wall of the installation shell, a connecting rod reciprocatingly arranged inside the piston cylinder and fixed to the lower surface of the sliding seat, and two infusion tubes fixed and communicated with the outer surface of the piston cylinder. The two separated ends of the two infusion tubes are respectively fixedly communicated with the liquid storage tank and the nozzle.

[0017] Preferably, the first trigger member includes a slider slidably arranged inside the sliding seat, a damping rod fixed to one side of the slider, and a second return spring.

The second trigger member includes a slide rail fixed to the outer surface of the installation shell, a sliding seat slidably arranged inside the slide rail, and a lever bolted to the outer surface of the sliding seat and abutted against the slider.

[0019] Preferably, a limiting stop block for limiting is fixed to the upper surface of the slider. A return top block adapted to the slider is fixed to one side of the installation shell close to the slide rail. An adapted abutting inclined surface is formed between the return top block and the slider. The lever is lower than the return top block.

[0020] The present invention has at least the following beneficial effects:

[0021] 1. When the slider is pushed by the lever to make a small displacement in the present invention, the reciprocating telescoping of the double-axis push rod drives the sliding seat to move back and forth through the pushing arm. When the sliding seat moves back and forth, it drives the sliding seat to reciprocate in cooperation with the deformation of the slider and the first return spring. When the sliding seat reciprocates, it drives the piston cylinder through the connecting rod, and pumps the anti-splash agent in the liquid storage tank to the nozzle through the infusion tube. The anti-splash agent quickly evaporates on the surface of the welding tube, absorbs heat, can reduce the temperature of the welding tube surface, and at the same time, the liquid film formed by the spray can increase the heat exchange area between the surface of the welding tube and the air, improving the heat dissipation efficiency.

[0022] 2. When the slider moves greatly in the present invention, the sliding seat drives the sliding seat to move to the leftmost side of the installation shell. When the sliding seat moves to the leftmost side, through the adapted inclined surface of the return top block, the sliding seat is retracted into the installation groove, and then the sliding seat is displaced to the rightmost side of the installation shell through the deformation of the first return spring. When the sliding seat moves to the rightmost side, the knocking member will knock on the outside of the welding tube, and at the same time drive the cleaning brush to abut against the outer surface of the welding tube through the dial block;

[0023] The elastic knocking block impacts the surface of the welding tube along with the movement of the sliding seat, knocking off large particles of welding slag. The dial block pushes the cleaning brush to scrape off the remaining welding slag, and finally uses a dust suction device to absorb the impurities.

[0024] 3. In the present invention, with the displacement of the sliding seat, the rolling shaft rolls in the reciprocating chute of the rotating cylinder, driving the rotation of the rotating cylinder. The rotation of the rotating cylinder drives the stirring of the liquid storage tank through the stirring shaft, improving the activity of the liquid. At the same time, the reciprocating motion energy of the cleaning structure is utilized to drive the stirring, eliminating the need for an additional motor or gas source and reducing energy consumption.

Specific embodiments

[0035] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments.

[0036] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0037] As Figures 1-8 shown, the welding device for easy conversion of automotive parts provided in this embodiment includes a frame 1, a conversion soldering station 2 rotatably arranged on the frame 1, and a welding pipe 5 arranged above the conversion soldering station 2 to form a welding device for automotive parts. An installation bracket 4 is arranged outside the welding pipe 5, and the welding pipe 5 slidably penetrates through the inside of the installation bracket 4. A horizontal plate 3 fixed to the frame 1 is welded on the outer surface of the installation bracket 4. There are two processing areas above the conversion soldering station 2. By rotating the conversion soldering station 2, it is convenient to convert automotive parts.

[0038] In this embodiment, a cleaning device 6 for cleaning the welding pipe 5 is arranged outside the mounting bracket 4; the cleaning device 6 is composed of a mounting shell 7, an output structure 8 arranged outside the mounting bracket 4, a liquid storage tank 9 fixed on the outer surface of the mounting shell 7, a cleaning structure 10 arranged inside the mounting shell 7, an infusion structure and a rotating cylinder 15. A cleaning brush 14 is arranged on one side of the mounting shell 7 close to the welding pipe 5, and a trigger part two 16 for cooperating with the cleaning structure 10 is arranged on the outer surface of the mounting shell 7. Specifically, the output structure 8 includes a double-axis push rod 802 fixedly arranged outside the mounting bracket 4, a push arm 803 and a connecting block 804 arranged on two output ends of the double-axis push rod 802, and the push arm 803 and the connecting block 804 are respectively connected with the trigger part two 16 and the welding pipe 5. It should be noted that the push arm 803 converts the linear motion of the double-axis push rod 802 into the reciprocating sliding displacement of the sliding seat 1001 of the cleaning structure 10 through the trigger part two 16, without additional sensors or electrical control, reducing the system complexity.

[0039] The rotating cylinder 15 is rotatably installed inside the mounting shell 7, and a stirring shaft 17 extending into the mounting shell 7 and fixed to one end of the rotating cylinder 15 is rotatably installed inside the liquid storage tank 9. Through the displacement of the sliding seat 1001, the rolling shaft 1007 rolls in the reciprocating chute 151 of the rotating cylinder 15, driving the rotating cylinder 15 to rotate. The rotation of the rotating cylinder 15 realizes the stirring of the liquid storage tank 9 through the stirring shaft 17, improving the activity of the liquid. At the same time, the reciprocating motion energy of the cleaning structure 10 is used to drive the stirring, without additional motors or air sources, reducing the energy consumption. The cleaning structure 10 includes a sliding seat 1001 slidably arranged inside the mounting shell 7, a knocking part 1002 and a trigger part one 1006 arranged outside the sliding seat 1001 and cooperating with the cleaning brush 14 and the trigger part two 16 respectively. A rolling shaft 1007 rotatably installed inside the sliding seat 1001 and rollingly cooperating with the rotating cylinder 15 is arranged.

[0040] It should be noted that the inside of the mounting shell 7 is hollow, and a mounting table 801 for supporting the double-axis push rod 802 is fixed on the outer surface of the mounting bracket 4. The push arm 803 is hinged between the bottom output end of the double-axis push rod 802 and the trigger part two 16. Through the reciprocating motion of the sliding seat 1001, the elastic knocking block 10022 of the knocking part 1002 knocks, shaking off the stubborn welding slag on the surface of the welding pipe 5 and improving the cleaning efficiency. A cushion is fixed outside the elastic knocking block 10022. The number of the cleaning devices 6 is two, and the two cleaning devices 6 are symmetrically arranged.

[0041] In this embodiment, the cleaning structure 10 further includes two guide rods 1003 fixed to the inner wall of the mounting shell 7. The sliding seat 1001 is slidably mounted on the two guide rods 1003. A first return spring 1004 surrounding the outside of the guide rod 1003 is fixed between the sliding seat 1001 and the mounting shell 7. A reciprocating chute 151 adapted to the rolling shaft 1007 is provided inside the rotating cylinder 15. The rolling shaft 1007 is displaced along one end of the reciprocating chute 151 through the sliding of the sliding seat 1001 to realize the rotational drive of the rotating cylinder 15. A support frame 13 is fixed to one side of the mounting shell 7 close to the welding pipe 5 by bolts. The cleaning brush 14 is slidably arranged inside the support frame 13. A dial block 1005 in abutting cooperation with the cleaning brush 14 is fixed to the outer surface of the sleeve 10021. A stop block in abutting cooperation with the dial block 1005 is fixed to the outer surface of the cleaning brush 14; the dial block 1005 is located in contact with the stop block, so as to drive the cleaning brush 14 to abut against the outer surface of the welding pipe 5; the elastic knocking block 10022 hits the surface of the welding pipe 5 as the sliding seat 1001 moves, knocking down large particle welding slag, and the dial block 1005 pushes the cleaning brush 14 to scrape off the remaining welding slag.

[0042] Specifically, the knocking member 1002 is composed of a sleeve 10021 and an elastic knocking block 10022. The sleeve 10021 is fixed to the side of the sliding seat 1001 away from the first return spring 1004. The elastic knocking block 10022 is slidably arranged inside the sleeve 10021, and one end of the elastic knocking block 10022 extends outside the mounting shell 7. The trigger member one 1006 includes a slider 10061 slidably arranged inside the sliding seat 1001, a damping rod 10062 fixed to one side of the slider 10061, and a second return spring 10063. An installation groove 10065 for installing the slider 10061 is provided inside the sliding seat 1001. The ends of the damping rod 10062 and the second return spring 10063 away from the sliding seat 1001 are both fixed to the inner wall of the installation groove 10065. Among them, a guiding groove 10064 for guiding the slider 10061 is provided inside the installation groove 10065. The trigger member two 16 includes a slide rail 1601 fixed to the outer surface of the mounting shell 7, a sliding seat 1602 slidably arranged inside the slide rail 1601, and a lever 1603 bolted to the outer surface of the sliding seat 1602 and in abutting cooperation with the slider 10061. The slider 10061 realizes buffered movement through the damping rod 10062 and the second return spring 10063.

[0043] To achieve different cleaning methods, a limiting stop block 10066 for limiting is fixed on the upper surface of the slider 10061. A reset top block 18 adapted to the slider 10061 is fixed on one side of the mounting shell 7 close to the slide rail 1601. An adapted abutting inclined surface is provided between the reset top block 18 and the slider 10061, and the lever 1603 is lower than the reset top block 18. The slide rail 1601 and the mounting frame 4 are bolted with a connecting arm to fix the mounting shell 7. In this embodiment, the infusion structure includes an infusion member 11 and a spray pipe 12 fixed on the upper surface of the support frame 13. The infusion member 11 includes a piston cylinder 1101 fixed on the inner bottom wall of the mounting shell 7, a connecting rod 1102 reciprocatingly arranged inside the piston cylinder 1101 and fixed to the lower surface of the sliding seat 1001, and two infusion pipes 1103 fixed and communicated with the outer surface of the piston cylinder 1101. The separated ends of the two infusion pipes 1103 are respectively fixed and communicated with the liquid storage tank 9 and the spray pipe 12.

[0044] In the use of this embodiment, the sliding seat 1602 of the trigger member two 16 moves along the slide rail 1601. By adjusting the amplitude of the sliding seat 1001, not only the spraying use is realized, but also the force can be stored for knocking.

[0045] It should be noted that the output stroke of the double-axis push rod 802 is adjustable. The push rod is equipped with a sensor, a programmable controller or a mechanical adjustment device, and the stroke can be changed by adjusting parameters or hardware. For example, in an automated production line, the stroke of the push rod is adjusted according to the product size. The double axis adopts a separated drive unit and is equipped with an independent transmission mechanism, and either output shaft can be driven separately through the control system.

[0046] When the lever 1603 pushes the slider 10061 to make a small displacement, the two output shafts of the double-axis push rod 802 move respectively. The bottom output shaft reciprocates telescopically, and drives the sliding seat 1602 to reciprocate back and forth through the push arm 803. When the sliding seat 1602 reciprocates back and forth, it drives the sliding seat 1001 to reciprocate in cooperation with the deformation of the slider 10061 and the first return spring 1004. When the sliding seat 1001 reciprocates, it drives the piston cylinder 1101 in cooperation with the connecting rod 1102, pumps the anti-splash agent in the liquid storage tank 9 to the spray pipe 12 through the infusion pipe 1103. The anti-splash agent quickly evaporates on the surface of the welding pipe 5, absorbs heat, can reduce the temperature of the surface of the welding pipe 5. At the same time, the liquid film formed by spraying can increase the heat exchange area between the surface of the welding pipe 5 and the air, improving the heat dissipation efficiency. The top output shaft of the double-axis push rod 802 intermittently drives the welding pipe 5 to move up and down, so that the welding pipe 5 rubs against the cleaning brush 14, thereby scraping off the residual welding slag;

[0047] After the surface temperature of the welding pipe 5 drops, the double-axis push rod 802 drives the slider 10061 to move significantly. When the slider 10061 moves significantly, the sliding seat 1001 is driven to move to the leftmost side of the mounting shell 7 through the sliding seat 1602. The matching inclined surface of the reset top block 18 is used to retract the slider 10061 into the mounting groove 10065. Then, the first reset spring 1004 is deformed to make the slider 1001 move to the rightmost side of the mounting shell 7. At this time, the knocking piece 1002 will knock the outside of the welding pipe 5. The displacement of the knocking piece 1002 will utilize the abutment of the shifting block 1005 and the stop block to drive the cleaning brush 14 to abut against the outer surface of the welding pipe 5 to scrape off the residual welding slag, and finally the impurities are absorbed by the dust collection equipment.

[0048] like Figures 1-8 As shown, the principle of the welding equipment for easy conversion of automobile parts provided in this embodiment is as follows:

[0049] After welding is completed, the welding pipe 5 slides axially along the mounting frame 4, and drives the output end of the double-axis push rod 802 to move through the connecting block 804, and the push arm 803 converts the horizontal displacement into the vertical movement of the trigger member 16;

[0050] The sliding seat 1602 in the trigger member 16 moves along the slide rail 1601. When the lever 1603 pushes the slider 10061 to move slightly, the sliding seat 1602 is driven to reciprocate back and forth through the push arm 803 by the reciprocating extension and contraction of the dual-axis push rod 802. When the sliding seat 1602 reciprocates back and forth, the deformation of the slider 10061 and the first return spring 1004 drives the sliding seat 1001 to reciprocate. When the sliding seat 1001 reciprocates, it cooperates with the connecting rod 1102 to drive the piston cylinder 1101, and the anti-splash agent in the liquid storage tank 9 is pumped to the nozzle 12 through the infusion tube 1103. The anti-splash agent evaporates quickly on the surface of the welding pipe 5 and absorbs heat, which can reduce the surface temperature of the welding pipe 5. At the same time, the liquid film formed by the spray can increase the heat exchange area between the surface of the welding pipe 5 and the air, thereby improving the heat dissipation efficiency.

[0051] After the surface temperature of the welding pipe 5 drops, the double-axis push rod 802 drives the slider 10061 to move significantly. When the slider 10061 moves significantly, the sliding seat 1602 drives the sliding seat 1001 to move to the leftmost side of the mounting shell 7. When the sliding seat 1602 moves to the leftmost side, the sliding seat 1602 is retracted into the mounting groove 10065 by the matching inclined surface of the reset top block 18, and then the sliding seat 1001 is moved to the rightmost side of the mounting shell 7 by the deformation of the first reset spring 1004. When the sliding seat 1001 moves to the rightmost side, the knocking member 1002 knocks the outside of the welding pipe 5, and at the same time, the cleaning brush 14 is driven by the shifting block 1005 to abut against the outer surface of the welding pipe 5.

[0052] The elastic knocking block 10022 moves along with the sliding seat 1001 to impact the surface of the welded pipe 5, knocking off large particle welding slag. The shifting block 1005 pushes the cleaning brush 14 to scrape off the residual welding slag, and finally a dust suction device is used to absorb the impurities.

[0053] As certain terms are used in the description and claims to refer to particular components, those skilled in the art should understand that hardware manufacturers may refer to the same component by different names. The description and claims do not distinguish components by the difference in name, but by the difference in function. As used throughout the description and claims, the term "comprising" is an open-ended term and should be interpreted as "including but not limited to". "Substantially" means within an acceptable error range. Those skilled in the art can solve technical problems within a certain error range and basically achieve the technical effect.
