Description

Technical Field

[0001] This invention relates to the field of shock absorber processing technology, specifically to a welding device for shock absorber processing. Background Technology

[0002] In fields such as heavy machinery and large vehicles, shock absorbers often need to be designed with large dimensions and heavy weight to meet vibration reduction requirements. When machining and welding these shock absorbers, a rotary fixture combined with welding equipment is conventionally used for circumferential weld processing. However, this method has significant drawbacks: First, the concentrated weight of large shock absorbers leads to excessive load on the rotary fixture, causing the clamping structure to loosen due to stress concentration. Second, during loading and unloading, a single or few clamping points are insufficient to stably fix the workpiece, easily leading to clamping instability due to positioning deviations. Third, during rotation, the torque generated by the integral drive structure is concentrated at the connection between the workpiece and the fixture, further increasing the risk of detachment. These problems not only affect welding quality but also pose serious safety hazards, necessitating a welding device that can distribute the load and enhance clamping stability. Summary of the Invention

[0003] The purpose of this invention is to provide a welding apparatus for processing shock absorbers, so as to solve the problems mentioned in the background art.

A spring is fixedly installed on the outer wall of the curved arm. The end of the spring away from the curved arm is fixedly connected to the inner wall of the L-shaped seat.

[0008] Furthermore, a negative pressure suction component is provided at the center of the workbench, and a positioning component is provided at the center of the negative pressure suction component.

[0009] Furthermore, the negative pressure suction component includes a negative pressure chamber and a negative pressure plate. The negative pressure chamber is located inside the base. The negative pressure plate is detachably installed in a through groove at the center of the workbench. A negative pressure hole is provided at the center of the negative pressure plate. A negative pressure pipeline connection port is connected inside the negative pressure chamber. A V-shaped partition plate is fixedly installed inside the negative pressure chamber. The V-shaped partition plate separates the negative pressure pipeline connection port from the negative pressure hole. A sieve hole is provided on one inclined surface of the V-shaped partition plate.

[0010] Furthermore, the positioning component includes mounting holes and connecting plates. The mounting holes are located on the top of the negative pressure plate, and there are multiple mounting holes arranged in a cross pattern. There are four connecting plates, and the top of the connecting plates has connecting holes with the same inner diameter as the mounting holes. The end of the connecting plate is provided with an integrally formed mounting head, and a soft silicone pad is fixedly provided at the end of the mounting head.

[0011] Furthermore, an elastic ring is fixedly sleeved on the outer wall of the lead screw, a friction ring is fixedly installed on the outer wall of the elastic ring, a friction ring is fixedly installed on the outer wall of the guide rail, the friction surface of the friction ring is in contact with the friction surface of the friction ring, and a throttle is fixedly installed on one end of the lead screw outside the guide rail.

[0012] Furthermore, the auxiliary feeding component includes a second base, an inclined plate fixedly installed on the top of the second base, the top of the inclined plate being flush with the upper surface of the workbench, a guide groove being provided in the inclined plate, a placement seat being slidably disposed on the top of the inclined plate, an internally threaded sleeve being fixedly installed on the inner wall of the placement seat, a second lead screw being internally threadedly connected to the internally threaded sleeve, the two ends of the second lead screw being rotatably connected to the bottom of the inclined plate through bearings, a driving assembly being provided inside the second base, and the driving end of the driving assembly being drively connected to the second lead screw.

[0013] Furthermore, the drive assembly includes a drive motor and a reducer. The drive motor is fixedly installed inside the base two.

[0014] Compared with the prior art, the beneficial effects of the present invention are: The radius of rotation of the welding device control box is adjusted by the rotation radius adjustment component, thereby adjusting the radius of rotation of the welding head. This is used to process shock absorbers with different radii. The height of the lifting seat is adjusted up and down by the electric slide rail, thereby adjusting the height of the welding head. This is used to weld different height parts of the shock absorber. The welding device control box and the welding head are connected by corrugated cable conduit and connecting cable conduit to ensure that the welding head can be controlled by the welding device control box throughout the welding process. When the welding head approaches the shock absorber, the elastic cleaning head will first contact the outer wall of the shock absorber. Because the curved arm can rotate, when adjusting the distance between the welding head and the shock absorber, it can also ensure that the elastic cleaning head contacts the outer surface of the shock absorber. By pulling the curved arm with a spring, when the curved arm is rotated under force, there will be no problem that the curved arm rotates too much, which would prevent the elastic cleaning head from contacting the outer wall of the shock absorber. Adjust the position of the connecting plate according to the radius of the shock absorber so that the soft silicone pad can abut against the outer surface of the shock absorber. Position the center of the shock absorber according to the selected mounting holes to ensure that there is no large positional displacement when welding the components to the shock absorber. The drive assembly drives the second lead screw to rotate, which in turn moves the internal threaded sleeve, which in turn moves the inclined plate. The movement of the inclined plate moves the shock absorber placed on it, bringing the shock absorber closer to the worktable, making it easier for workers to transfer the shock absorber to the worktable.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] Example 1: Please refer to Figures 1-8 The present invention provides a technical solution: a welding device for processing shock absorbers, including a base 1, a workbench 2 fixedly installed on the top of the base 1, a support frame 4 arranged behind the base 1, a welding component 3 arranged directly above the workbench 2, the welding component 3 being installed on the support frame 4, and an auxiliary feeding component 5 arranged on the front of the base 1. Welding component 3 includes an electric turntable 301, which is fixedly installed on the inner wall of the top of the support frame 4. A mounting plate 302 is fixedly installed on the rotating end of the electric turntable 301. A rotation radius adjustment component 303 is provided at the bottom of the mounting plate 302. A welding device control box 304 is fixedly connected to the sliding end of the rotation radius adjustment component 303. An electric slide rail 305 is fixedly installed at the bottom of the welding device control box 304. A lifting seat 306 is fixedly connected to the sliding end of the electric slide rail 305. An L-shaped seat 309 is fixedly installed at the center of the lifting seat 306. A welding head 3010 is fixedly installed at the bottom end of the L-shaped seat 309. A pre-cleaning component 308 is provided at the bottom end of the L-shaped seat 309. The pre-cleaning component 308 is located in both the front and rear directions of the welding head 3010. The terminal is connected to a connecting cable conduit 3011, and the top of the connecting cable conduit 3011 is connected to a corrugated cable conduit 307. The corrugated cable conduit 307 is connected to the output end of the welding device control box 304. The radius of the rotation trajectory of the welding device control box 304 is adjusted by the rotation radius adjustment component 303, thereby adjusting the radius of the rotation trajectory of the welding head 3010. This is used to process shock absorbers with different radii. The height of the lifting seat 306 is adjusted up and down by the electric slide rail 305, thereby adjusting the height of the welding head 3010. This is used to weld different height parts of the shock absorber. The corrugated cable conduit 307 and the connecting cable conduit 3011 connect the welding device control box 304 and the welding head 3010 to ensure that the welding head 3010 can always be controlled by the welding device control box 304 during the welding process. Two rotation radius adjustment components 303 are provided, and the two rotation radius adjustment components 303 are symmetrically arranged with respect to the center of the mounting plate 302. They are used to set two sets of symmetrically arranged welding heads 3010, so that the shock absorber can be welded at the same time, thereby improving welding efficiency. The rotation radius adjustment assembly 303 includes a guide rail 3031, which is fixedly installed at the bottom of the mounting plate 302. A sliding seat 3032 is slidably arranged inside the guide rail 3031. A lead screw 3033 is rotatably connected to the inner wall of the guide rail 3031 through a bearing. The sliding seat 3032 is threaded onto the lead screw 3033. The welding device control box 304 is fixedly installed at the bottom of the sliding seat 3032. By rotating the lead screw 3033, the sliding seat 3032 moves along the guide rail 3031, thereby driving the welding device control box 304 to move, which is used to adjust the rotation trajectory radius of the welding device control box 304. The pre-cleaning assembly 308 includes a groove 3081, which is formed on the outer wall of the bottom end of the L-shaped base 309. A curved arm 3082 is rotatably connected to the groove 3081 via a pin. A hollow head 3084 is fixedly installed at the end of the curved arm 3082 away from the L-shaped base 309. An elastic cleaning head 3085 is fixedly installed on the outer wall of the hollow head 3084. A spring 3083 is fixedly installed on the outer wall of the curved arm 3082. The end of the spring 3083 away from the curved arm 3082 is fixed to the inner wall of the L-shaped base 309. When the welding head 3010 approaches the shock absorber, the elastic cleaning head 3085 will first contact the outer wall of the shock absorber. Because the bending arm 3082 is rotatable, when adjusting the distance between the welding head 3010 and the shock absorber, it can also ensure that the elastic cleaning head 3085 contacts the outer surface of the shock absorber. By pulling the bending arm 3082 with the spring 3083, when the bending arm 3082 is rotated under force, there will be no problem that the bending arm 3082 rotates too much, which would prevent the elastic cleaning head 3085 from contacting the outer wall of the shock absorber. A negative pressure suction component 6 is provided at the center of the workbench 2, and a positioning component 7 is provided at the center of the negative pressure suction component 6. The negative pressure suction component 6 is used to attract the fumes generated during the welding process, and the positioning component 7 is used to position the shock absorber. The negative pressure suction component 6 includes a negative pressure chamber 601 and a negative pressure plate 605. The negative pressure chamber 601 is located inside the base 1. The negative pressure plate 605 is detachably mounted in a through groove at the center of the workbench 2. A negative pressure hole 606 is provided at the center of the negative pressure plate 605. A negative pressure pipeline connection port 602 is connected inside the negative pressure chamber 601. A V-shaped partition plate 603 is fixedly installed inside the negative pressure chamber 601, which connects the negative pressure pipeline connection port 602 to the negative pressure hole 606. The V-shaped partition plate 603 is separated by a sieve hole 604 on one of its inclined surfaces. The negative pressure pipeline in the workshop is connected to the inside of the negative pressure chamber 601 through the negative pressure pipeline connection port 602, so that the inside of the negative pressure chamber 601 is in a negative pressure state. The negative pressure plate 605 is used to support the shock absorber. At the same time, the negative pressure hole 606 on the negative pressure plate 605 is also in a negative pressure state, which can draw the fumes generated during welding into the negative pressure chamber 601. The V-shaped partition plate 603 can intercept particulate matter in the airflow. The positioning component 7 includes mounting holes 701 and connecting plates 702. The mounting holes 701 are located on the top of the negative pressure plate 605, and there are multiple mounting holes 701 arranged in a cross pattern. The connecting plates 702 have four mounting holes 703 on their top. The inner diameter of the connecting holes 703 is the same as the inner diameter of the mounting holes 701. The end of the connecting plate 702 is provided with an integrally formed mounting head 704. A soft silicone pad 705 is fixedly mounted on the end of the mounting head 704. The position of the connecting plate 702 is adjusted according to the radius of the shock absorber so that the soft silicone pad 705 can abut against the outer surface of the shock absorber. The center of the shock absorber is positioned according to the selected mounting holes 701, thereby ensuring that there is no large positional displacement when the welding component 3 welds the shock absorber. An elastic ring 10 is fixedly sleeved on the outer wall of the lead screw 3033. A friction ring 9 is fixedly installed on the outer wall of the elastic ring 10. A friction ring 8 is fixedly installed on the outer wall of the guide rail 3031. The friction surface of the friction ring 9 is in contact with the friction surface of the friction ring 8. A throttle 11 is fixedly installed at one end of the lead screw 3033 outside the guide rail 3031. The elastic ring 10 is used to connect the friction ring 9 and the lead screw 3033. When the lead screw 3033 makes a circular motion, it will not rotate due to the friction of the friction rings 8 and 9, thus ensuring that the radius of motion of the welding head 3010 does not change during the welding process.

[0019] Working Principle: In use, place the shock absorber at the center of the negative pressure plate 605, then install the four connecting plates 702 sequentially, so that the soft silicone pad 705 rests against the outer wall of the shock absorber, providing simple limiting for the shock absorber. Then, turn the handle 11 to drive the lead screw 3033 to rotate, causing the sliding seat 3032 to move, adjusting the position of the welding head 3010 so that it is close to the shock absorber. Then, turn on the electric turntable 301 to drive the mounting plate 302 to rotate. The rotation of the mounting plate 302 drives the rotation radius adjustment component 303 to rotate, which in turn drives the welding device control box 304 to rotate. The rotation of the welding device control box 304 drives the electric slide rail 305 to rotate, which in turn drives the lifting seat 306 to rotate. The rotation of the lifting seat 306 drives the L-shaped seat 309 to rotate, which in turn drives the welding head 3010 to rotate, simultaneously welding... The device control box 304 controls the welding head 3010 to start welding. When welding at different heights is required, the electric slide rail 305 is activated to move the lifting seat 306 up or down, which in turn moves the welding head 3010 up or down. During this process, the bending arm 3082 is pushed by force and then the rotation angle changes to ensure that the elastic cleaning head 3085 is always in contact with the surface of the shock absorber, ensuring that the surface of the shock absorber is cleaned. During the welding process, the valve at the connection between the negative pressure pipeline port 602 and the negative pressure chamber 601 is opened, so that the negative pressure chamber 601 becomes negative pressure. The negative pressure plate 605 is used to support the shock absorber. At the same time, the negative pressure hole 606 on the negative pressure plate 605 is also negative pressure, which can draw the fumes generated during welding into the negative pressure chamber 601. The V-shaped partition plate 603 can intercept particulate matter in the airflow.

The terminal is connected to a connecting cable conduit 3011, and the top of the connecting cable conduit 3011 is connected to a corrugated cable conduit 307. The corrugated cable conduit 307 is connected to the output end of the welding device control box 304. The radius of the rotation trajectory of the welding device control box 304 is adjusted by the rotation radius adjustment component 303, thereby adjusting the radius of the rotation trajectory of the welding head 3010. This is used to process shock absorbers with different radii. The height of the lifting seat 306 is adjusted up and down by the electric slide rail 305, thereby adjusting the height of the welding head 3010. This is used to weld different height parts of the shock absorber. The corrugated cable conduit 307 and the connecting cable conduit 3011 connect the welding device control box 304 and the welding head 3010 to ensure that the welding head 3010 can always be controlled by the welding device control box 304 during the welding process.

The drive motor 5061 is fixedly installed inside the base 501. The output end of the drive motor 5061 is connected to the input end of the reducer 5062.

The guide rail 12 and roller 14 are set to limit the placement seat 503. The corrugated shielding cloth 13 is set to cover the lead screw 504 to prevent debris from falling onto the lead screw 504.

The rotation of the lead screw 504 drives the internal threaded sleeve 505 to move, which in turn drives the inclined plate 502 to move. The movement of the inclined plate 502 drives the shock absorber placed on it to move, so that the shock absorber is closer to the worktable 2, making it convenient for the worker to transfer the shock absorber to the worktable 2.
