Description

Technical Field

[0001] This utility model relates to a welding device, and more particularly to a swing welding device for the inner and outer circumferential seams of a jack cylinder. Background Technology

[0002] As one of the core components of a jack, the jack cylinder body requires high-precision welding techniques to ensure its sealing and performance. This process includes selecting appropriate welding methods, optimizing welding process parameters, and implementing preheating and post-heating measures to prevent welding deformation and cracks.

[0003] According to the patent authorized publication number CN209424186U, a swing welding device for the inner and outer circumferential seams of a jack cylinder is disclosed, including a bed, a welding chuck, a gas shielded welding torch, a transverse lifting system, and a water cooling mechanism. The welding chuck is axially rotatable above one end of the bed along the length of the bed, and a water cooling mechanism is provided above the other end of the bed. The transverse lifting system is movable above the bed along the length of the bed. The gas shielded welding torch includes an outer welding torch on the X1 axis and an inner welding torch on the X2 axis. Although the aforementioned patent achieves the welding of the jack cylinder by controlling the welding chuck on the bed to rotate the jack cylinder body, and then adjusting the positions of the welding torches on the outer side of the X1 axis and the inner side of the X2 axis to align them with the inner and outer circumferential seams of the jack cylinder body, it requires manual spot welding of the jack cylinder body and base before welding the inner and outer circumferential seams to prevent detachment during subsequent welding. However, relying on manual welding cannot guarantee the accuracy of spot welding, making it easy for errors to occur between the jack cylinder body and base during the welding process, thus affecting the welding quality of subsequent welding work.

[0004] To address the aforementioned issues, it is necessary to design a swing welding device for the inner and outer circumferential seams of a jack cylinder. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, which is prone to errors and has low efficiency when spot welding the jack cylinder body and base manually, the technical problem to be solved by this utility model is to provide a swing welding device for the inner and outer circumferential seams of the jack cylinder body.

[0006] The technical implementation scheme of this utility model is as follows: a oscillating welding device for the inner and outer circumferential seams of a jack cylinder, comprising a welding table, a first motor, a three-jaw chuck, a third electric slide rail, a second motor, a support frame, a cylinder, a fixed plate, a rack, a gear, a grab rod, and a welding mechanism. A welding mechanism for welding the jack cylinder body is provided on the top of the welding table. The first motor is installed at the center of the top of the welding table, and the output shaft of the first motor is connected to the three-jaw chuck. A third electric slide rail is provided on the side of the welding table opposite to the welding mechanism. A second motor is installed on the slider of the third electric slide rail. The output shaft of the second motor is connected to the support frame. A gear is rotatably connected to the support frame, and a grab rod is fixedly connected to the gear. A cylinder is installed on the support frame, and the piston rod of the cylinder is connected to the fixed plate. The fixed plate is slidably connected to the support frame, and a rack that meshes with the gear is fixedly connected to the side of the fixed plate facing away from the cylinder.

[0007] Furthermore, the welding mechanism includes a first electric slide rail, a second electric slide rail, a first welder, and a second welder. The first electric slide rail is installed on the top of the welding table, and the second electric slide rail is fixedly connected to the slider of the first electric slide rail. The first welder and the second welder are installed on the second electric slide rail.

[0008] Furthermore, the end of the support frame away from the second motor is designed in a circular shape, and at least three gears are evenly spaced at the end of the support frame away from the second motor.

[0009] Furthermore, the welding station is equipped with a protective shell to block sparks, and a door panel is rotatably connected to the protective shell.

[0010] Furthermore, a viewing window is provided on the door panel, and a light-shielding plate is fixedly connected to the viewing window.

[0011] Furthermore, an air filter is installed on the top of the protective housing, with the air intake end of the air filter extending into the interior of the protective housing.

[0012] The present invention has the following advantages: 1. Through the coordinated work of components such as a three-jaw chuck, cylinder, rack, gear and grab bar, the present invention can achieve precise docking of the cylinder body of the jack and the base, ensuring the accuracy of workers during spot welding, reducing manual intervention and avoiding the influence of errors that are easily caused by manual spot welding.

[0013] 2. This utility model, through the design of an air filter, can draw out the fumes generated during welding, filter and purify them before discharge, thereby preventing the fumes from polluting the working environment and ensuring the safety of workers.

[0014] 3. This utility model effectively blocks sparks and fumes generated during welding through the design of the protective shell and door panel, preventing them from spreading outward and thus protecting the environment of the production workshop. At the same time, the design of the light shield avoids the strong welding light from harming the workers' eyes and improves the flexibility of the device. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Example: A swing welding device for the inner and outer circumferential seams of a jack cylinder, such as... Figures 1-4As shown, the assembly includes a welding table 1, a first motor 6, a three-jaw chuck 7, a third electric slide rail 8, a second motor 9, a support frame 10, a cylinder 11, a fixing plate 12, a rack 13, a gear 14, and a gripper 15. A welding mechanism for welding the jack cylinder is installed on the top of the welding table 1. The first motor 6 is installed at the center of the top of the welding table 1, and the output shaft of the first motor 6 is connected to the three-jaw chuck 7. A third electric slide rail 8 is located on the side of the welding table 1 opposite to the welding mechanism. A second motor 9 is installed on the slider of the third electric slide rail 8, and the output shaft of the second motor 9 is connected to the support frame 10. A gear 14 is rotatably connected to the support frame 10, and a gripper 15 is fixedly connected to the gear 14. A cylinder 11 is installed on the support frame 10. The piston rod is connected to a fixed plate 12, which is slidably connected to the support frame 10. A rack 13 that meshes with the gear 14 is fixedly connected to the side of the fixed plate 12 facing away from the cylinder 11. Here, the end of the support frame 10 away from the second motor 9 is designed in a circular shape. At least three gears 14 are evenly spaced at the end of the support frame 10 away from the second motor 9. When the cylinder 11 is started, the piston rod of the cylinder 11 extends outward. The piston rod of the cylinder 11 drives the fixed plate 12 to slide downward. The fixed plate 12 drives the rack 13 to move downward. During the movement, the rack 13 drives the gear 14 to rotate counterclockwise, causing the grab rod 15 fixed to the gear 14 to flip upward, so that the grab rod 15 contacts the jack cylinder and remains in contact.

[0022] like Figure 2 As shown, the welding mechanism includes a first electric slide rail 2, a second electric slide rail 3, a first welder 4, and a second welder 5. The first electric slide rail 2 is installed on the top of the welding table 1. The second electric slide rail 3 is fixedly connected to the slider of the first electric slide rail 2. The first welder 4 and the second welder 5 are installed on the second electric slide rail 3. When the second electric slide rail 3 is activated, it drives the slider to slide, which in turn moves the first welder 4 and the second welder 5 so that they correspond to the inner and outer circumferential seams of the jack cylinder. Then, the first electric slide rail 2 is activated, driving the slider to slide downward. The slider of the first electric slide rail 2 drives the second welder 5 to slide downward, bringing the first welder 4 and the second welder 5 closer to the jack cylinder. After that, the second electric slide rail 3 is activated again to precisely control the first welder 4 and the second welder 5, ensuring that they are in the correct operating positions.

[0023] like Figure 1As shown, the welding station 1 is equipped with a protective shell 101 to block sparks. A door panel 102 is rotatably connected to the protective shell 101. A viewing window is provided on the door panel 102, and a light shield 103 is fixedly connected to the viewing window of the door panel 102. Here, the protective shell 101 and the door panel 102 can block the sparks and fumes generated during the welding process from spreading outward, preventing sparks and fumes from polluting the production workshop and ensuring the quality of the working environment. At the same time, the light shield 103 is made of glass material that can prevent strong light from penetrating, which can facilitate workers to observe the working status of the device, avoid strong light generated during welding from damaging workers' eyes, and improve the flexibility and practicality of the device.

[0024] like Figure 1 As shown, an air filter 16 is installed on the top of the protective housing 101. The air intake end of the air filter 16 extends into the interior of the protective housing 101. Here, the design of the air filter 16 can draw out the fumes generated during welding, allowing the fumes to enter the interior of the air filter 16. After being filtered and purified by the air filter 16, the fumes are discharged to the outside, preventing pollution of the working environment and ensuring the safety of workers.

[0025] This device is used for welding the inner and outer circumferential seams of a jack cylinder. In use, pulling the door panel 102 outwards causes it to flip, removing the protective shell 101 and opening the device. Then, the jack base is secured by sliding the blocks on the three-jaw chuck 7. After this, the jack cylinder is placed on the gripper rod 15, and the cylinder 11 is activated. The piston rod of the cylinder 11 extends outwards, causing the fixing plate 12 to slide downwards. The fixing plate 12 then moves the rack 13 downwards, causing the rack 13 to rotate counterclockwise, which in turn rotates the gear 14. This causes the gripper rod 15, which is fixed to the gear 14, to flip upwards, bringing it into contact with and maintaining contact with the jack cylinder, thus securing the jack cylinder. Then, the second motor 9 is activated, driving the output shaft to rotate. The output shaft of the second motor 9 causes the support frame 10 to flip downwards, making it perpendicular to the welding table 1. The jack cylinder body rotates downward with the support frame 10 and aligns with the jack base on the three-jaw chuck 7. Then, the third electric slide rail 8 is activated, driving the slider to slide downward. The slider of the third electric slide rail 8 moves the support frame 10 downward, causing the jack cylinder body on the support frame 10 to contact the jack base. Afterward, the jack cylinder body and the jack base are spot welded manually. After completion, the cylinder 11 is activated, and the piston rod of the cylinder 11 retracts inward. The piston rod of the cylinder 11 drives the rack 13 connected to the cylinder 11 via the fixed plate 12 to slide upward. Then, the gear 14 meshing with the rack 13 rotates clockwise, causing the grab rod 15 on the gear 14 to flip downward. The grab rod 15 is no longer in contact with the jack cylinder body. Then, the third electric slide rail 8 is activated, and the slider of the third electric slide rail 8 moves the support frame 10 upward, causing the grab rod 15 to exit the jack cylinder body. This completes the initial welding of the inner and outer circumferential seams of the jack cylinder. Next, the second electric slide rail 3 is activated, driving the slider to slide. The slider of the second electric slide rail 3 moves the first welder 4 and the second welder 5, aligning them with the inner and outer circumferential seams of the jack cylinder. Then, the first electric slide rail 2 is activated, driving the slider to slide downwards. The slider of the first electric slide rail 2 moves the second welder 5 downwards, bringing the first welder 4 and the second welder 5 closer to the jack cylinder. Then, the second electric slide rail 3 is activated again to precisely control the first welder 4 and the second welder 5, ensuring they are in the correct operating positions. Then, the first welder 4 and the second welder 5 are activated to weld the inner and outer circumferential seams of the jack cylinder, thus completing the welding work.
