Description

Technical Field

[0001] This application relates to the field of housing welding technology, and in particular to a welding fixture for processing automotive air filter housings. Background Technology

[0002] In the manufacturing process of automotive air filters, the welding of the housing is one of the key steps, as its processing quality and efficiency directly affect the overall performance of the filter and the production cycle. Automotive air filter housings typically consist of an upper housing and a lower housing. After welding, the internal space of the upper and lower housings is used to install the filter element. Welding fixtures are required when welding the upper and lower housings of the automotive air filter.

[0003] In existing technologies, when welding automotive air filter housings, the lower housing of the air filter is typically clamped and fixed on a welding fixture first. Then, the upper housing is placed and aligned with the area on the lower housing to be welded. Next, the operator holds the welding torch in one hand and presses the upper housing onto the lower housing with the other to perform the welding operation. However, this method requires continuous hand support of the upper housing during the welding process. Even slight shaking can cause misalignment of the weld joint, easily leading to defects such as incomplete welding, weld beads, and uneven joints. This not only inconveniences the welding operation but also affects the sealing performance and structural strength of the housing, resulting in an increased product defect rate. Furthermore, after welding, the welded upper and lower housings must be manually removed, increasing the labor intensity of the workers.

[0004] Therefore, we propose a welding fixture for machining automotive air filter housings to solve the above problems. Utility Model Content

[0025] See Figure 1 , Figure 2 , Figure 3 and Figure 4This application provides a welding fixture for processing automotive air filter housings, including a machine base 1. A clamping, fixing, and transferring mechanism 2 is provided on the top of the machine base 1. The clamping, fixing, and transferring mechanism 2 is used to clamp and fix the upper and lower housings of the automotive air filter, and can transfer the welded upper and lower housings, thereby reducing the labor intensity of workers.

Bearing plate 23 is fixedly installed on the top of vertical shaft 22. The lower housing clamping assembly is mounted on the bearing plate 23 and is used to clamp and fix the lower housing of the automotive air filter. Motor 27 is fixedly installed on the top of the bearing plate 23. Motor 27 is a reversible motor. Column 28. A rectangular hole 29 is provided on one side of the column 28, and a shaft seat 210 is fixedly installed on the bottom inner wall of the rectangular hole 29. A lead screw 211 is rotatably installed on the top of the shaft seat 210. A lifting seat 212 is threaded onto the lead screw 211. A second motor 213 is fixedly installed on the top of the column 28, and the output shaft end of the second motor 213 is fixedly connected to the top end of the lead screw 211. The second motor 213 is a reversible motor. A U-shaped plate 214 is fixedly installed on one side of the lifting seat 212. The upper housing clamping assembly is set on the U-shaped plate 214. 4. The lower housing clamping assembly is used to clamp and fix the upper housing of the car air filter. Motor 213 is used to control the rotation of the lead screw 211, which can control the vertical lifting of the lifting seat 212, so that the U-shaped plate 214 and the upper housing clamping assembly follow the lifting. On the one hand, the upper housing can be clamped and fixed on the lower housing to prevent the upper and lower housings from shifting during welding. On the other hand, the welded and fixed upper and lower housings can be lifted above the lower housing clamping assembly. Motor 27 is used to control the rotation of the column 28, so that the welded upper and lower housings can be transferred.

[0026] In this embodiment, the lower housing clamping assembly includes two pads 24, two electric telescopic rods 25, and two clamping plates 26. Both pads 24 are fixedly mounted on the top of the support plate 23. The two electric telescopic rods 25 are respectively fixedly mounted on the top of their respective pads 24. The two clamping plates 26 are respectively fixedly mounted on the output shaft ends of their respective electric telescopic rods 25.

[0028] In this embodiment, multiple handles 219 are fixedly installed on the outer circular wall of the bearing plate 23. The multiple handles 219 are distributed in a ring at equal intervals. The two sides of the lifting seat 212 slide against the inner walls of the two sides of the rectangular hole 29. The design of the handles 219 facilitates manual rotation of the bearing plate 23, so as to facilitate the comprehensive welding of the lower shell and the upper shell. By designing the two sides of the lifting seat 212 to slide against the inner walls of the two sides of the rectangular hole 29, it can be ensured that the lifting seat 212 rises and falls smoothly and steadily within the rectangular hole 29. A damping ring 4 is fixedly installed on the top of the machine base 1, located below the bearing plate 23. The upper surface of the damping ring 4 makes damping sliding contact with the lower surface of the bearing plate 23. The design of the damping ring 4 can limit the bearing plate 23 from rotating on its own, ensuring that the bearing plate is always in a stable state during the welding process, and further improving the welding position accuracy.

[0029] In this embodiment, a conveyor frame 5 is fixedly installed on the left side of the machine base 1, and a conveyor belt 6 is rotatably installed inside the conveyor frame 5. The design of the conveyor belt 6 allows the welded and fixed lower and upper shells to be transferred away to facilitate subsequent processing steps. The conveyor frame 5 is equipped with multiple conveyor rollers and a conveyor motor. The conveyor belt 6 is rotatably sleeved on the conveyor rollers. The output shaft end of the conveyor motor is fixedly connected to the conveyor roller located on the far side. By controlling the operation of the conveyor motor, the rotation of the conveyor belt 6 can be controlled.

[0030] In this embodiment, an inclined reinforcing plate 7 is fixedly installed at the bottom of the conveyor frame 5. The bottom of the reinforcing plate 7 is fixedly connected to the left side wall of the machine base 1. The design of the reinforcing plate 7 is to enhance the reliability of the installation and fixation of the conveyor frame 5.

[0031] In this embodiment, an electric welding machine 8 is fixedly installed on the top right side of the machine base 1. A welding gun 9 is fixedly connected to one side of the electric welding machine 8 through a wire. The upper and lower shells are welded by holding the welding gun 9.

[0032] In this embodiment, motor 27, motor 213, electric telescopic pole 25, and electric telescopic pole 215 can all be purchased on the market. Their wiring connection methods and control methods are mature technologies in this field and have been fully disclosed. Therefore, they will not be described again in this article.

[0033] With the above structure, the working principle of the welding fixture for processing automotive air filter housings provided in this application is as follows: First, place the lower housing of the car air filter between the two clamps 26 on the support plate 23, start the two electric telescopic rods 25 to extend and control the two clamps 26 to move closer to the middle. By contacting the outer wall of the lower housing with the anti-slip rubber pad 217 and applying clamping force, the lower housing can be firmly fixed on the support plate 23 to prevent displacement during subsequent welding. Next, place the upper housing of the car air filter on the lower housing and position the welding area. Start motor 213. The output shaft of motor 213 drives the lead screw 211 to rotate, causing the lifting seat 212 to drive the two electric telescopic rods 215, the two clamping plates 216, and the two anti-slip rubber pads 218 to rise and fall vertically. When the two clamping plates 216 are adjusted to a suitable position to clamp the upper housing, stop motor 213. Then, control the two electric telescopic rods 215 to extend and control the two clamping plates 216 to clamp in the middle. The anti-slip rubber pads 218 contact the outer wall of the upper housing and apply clamping force, thus firmly fixing the upper housing on the lower housing. During subsequent welding, there is no need for manual support and fixation of the upper housing, making the welding operation smoother. After the upper shell is clamped and fixed to the lower shell, the operator can take the welding gun 9 to perform welding operations at the connection between the upper shell and the lower shell. During the welding process, the bearing plate 23 can be rotated by manually pushing one of the handles 219, which makes it convenient to perform a full rotation welding operation at the connection between the upper shell and the lower shell. After welding is completed, push handle 219 to rotate in the opposite direction. Handle 219 drives bearing plate 23 to rotate in the opposite direction back to the initial position. Then control the two electric telescopic rods 25 to retract and reset, releasing the clamping and fixing of the lower shell. Then control motor 213 to run, controlling the lifting seat 212 to rise, which can lift the welded upper shell and lower shell above clamping plate 26. Then control motor 27 to run, its output shaft drives column 28 and the welded upper shell and lower shell to rotate 180°, which can transfer the welded upper shell and lower shell to the top of conveyor belt 6. Next, control motor 213 to run in reverse, which can lower the welded upper shell and lower shell onto conveyor belt 6. Finally, control the two electric telescopic rods 215 to retract and reset, which can release the clamping and fixing of the upper shell. By controlling the rotation of conveyor belt 6, the welded upper shell and lower shell can be transported away for subsequent processing. This eliminates the need for manual operation to lift and move the welded upper shell and lower shell, reducing the amount of manual labor. After the welded upper and lower housings are transported away, motor 27 can be controlled to run in reverse, which will rotate column 28 180° in the opposite direction to return it to its initial position. Following the above operating steps, the next automotive air filter housing can be welded.
