Description

Technical Field

[0001] This invention relates to the technical field of component welding, and more particularly to a welding machine for quickly fixing automobile lifting mechanism components. Background Technology

[0002] With the rapid development of the automotive industry and the increasing demands for maintenance efficiency, car lifts, as an indispensable piece of equipment in the automotive repair process, directly affect the quality and efficiency of repair work in terms of performance and reliability. Currently, most car lifts on the market consist mainly of a pivot, cantilever, and tie plate. These key components usually need to be connected through precision welding processes to ensure the stability and safety of the entire mechanism.

[0003] However, in traditional welding processes, the positioning and initial fixing of cantilever and tie plates is a complex and time-consuming process. Specifically, such as Figure 12 As shown, in order to ensure the accurate relative position of the cantilever and the tie plate during the welding process, the operator usually manually inserts a cylinder into the round holes of the cantilever and the tie plate in sequence to achieve the initial positioning of the two. Then, the cantilever and the tie plate are temporarily fixed by spot welding. After that, the cylinder is removed from the round hole, and finally the welding robot completes the final welding operation. This process is not only labor-intensive, but also inefficient. Especially in large-scale production, this manual operation method will greatly limit the improvement of production efficiency.

[0004] More importantly, traditional methods also present challenges in achieving precise alignment. On the one hand, if the diameter of the cylinder used is exactly the same as the diameter of the hole on the cantilever and tie plate, although a high degree of coaxiality can be guaranteed, it is difficult to complete the insertion quickly and accurately in actual operation, which increases the difficulty of the work. On the other hand, if the diameter of the cylinder is slightly smaller than the diameter of the hole, although it is easy to insert, it cannot effectively guarantee the coaxiality between the holes on the cantilever and tie plate, thus affecting the overall stability and load-bearing capacity of the structure during subsequent use. Once there is a coaxiality deviation between the cantilever and tie plate, it may not only cause abnormal wear of the shaft, cantilever and tie plate when bearing the weight of the car, but may also cause safety accidents due to structural instability, seriously affecting the service life and safety performance of the car lift. Summary of the Invention

[0005] In view of this, the present invention provides a fast-fixing welding machine for automobile lifting mechanism components, which can overcome the shortcomings of the prior art when welding cantilever and tie plate. It requires manual insertion of the cylinder into the round hole of the cantilever and tie plate for initial positioning, and the cylinder needs to be pulled out after spot welding. The whole operation process is relatively troublesome, the work efficiency is low, and it is difficult to quickly and accurately complete the insertion work and ensure the coaxiality between the round holes of the cantilever and tie plate.

[0006] A rapid-fixing welding machine for automotive lifting mechanism components includes: a support frame with vertical holes; a welding robot mounted on the top of the support frame; a lifting assembly mounted on the support frame; a mounting cylinder mounted on the lifting assembly, which drives the mounting cylinder to move up and down, and the mounting cylinder is located directly below the vertical holes; a vertical tube connected to the mounting cylinder; a first electric push rod mounted inside the mounting cylinder; a lifting rod slidably connected inside the vertical tube, with its lower end connected to the telescopic rod of the first electric push rod; a conical block connected to the lifting rod; a sliding rod circumferentially slidably connected to the vertical tube, with symmetrical grooves and inclined surfaces on the sliding rod, the conical block engaging with the inclined surfaces; a ring spring fitted inside the grooves; a conveying assembly mounted on the support frame for conveying the cantilever to the top of the mounting cylinder; and a feeding assembly mounted on the support frame for placing the inclined plate on top of the cantilever.

[0007] To further explain, the lifting assembly includes: a fixed frame connected to the support frame; a second electric push rod mounted on the fixed frame; a conical platform connected to the telescopic rod of the second electric push rod; and a movable connecting mechanism located on the top of the conical platform for movably connecting the conical platform and the mounting cylinder.

[0008] To further explain, the movable connection mechanism includes: a connecting rod connected to the bottom of the mounting cylinder; a connecting plate connected to the lower end of the connecting rod, with the bottom of the connecting plate contacting the top of the conical platform; a spring plate, with its two ends connected to the conical platform and the connecting plate respectively; and a limiting cover connected to the top of the conical platform, with a through hole on the limiting cover through which the connecting rod passes.

[0009] To further explain, the conveying assembly includes: a conveyor mounted on a support frame; a limiting plate circumferentially connected to the conveyor belt; and a stabilizing mechanism mounted on the conveyor for stabilizing the cantilever conveyed on the conveyor.

[0010] To further explain, the stabilizing mechanism includes: a support plate connected to the top of the conveyor frame; and a bar magnet connected to the side of the support plate.

[0011] To further explain, the feeding assembly includes: a translation mechanism mounted on the support frame; a lifting frame slidably mounted on the translation mechanism, which drives the lifting frame to move horizontally; limit rods connected to the lifting frame at intervals; vertical plates symmetrically connected to the lifting frame; a third electric push rod mounted on the vertical plate; a mounting plate connected to the telescopic rod of the third electric push rod; a square magnet connected to the mounting plate; and a fourth electric push rod mounted on the translation mechanism, with the telescopic rod of the fourth electric push rod connected to the lifting frame.

[0012] To further explain, the translation mechanism includes: a connecting frame connected to the support frame; a sliding frame slidably connected to the connecting frame, and the lifting frame slidably connected to the sliding frame; a fourth electric push rod fixedly connected to the sliding frame; and a fifth electric push rod installed on the connecting frame, with the telescopic rod of the fifth electric push rod connected to the sliding frame.

[0013] Further explanation: It also includes: a mounting bracket connected to the support frame; a rotating clamp rod symmetrically connected to the mounting bracket; and a rotating assembly mounted on the mounting bracket for driving the rotating clamp rod to rotate and clamp the cantilever.

[0014] To further explain, the rotating assembly includes: a sliding plate, slidably connected to the mounting bracket; a driving rack, symmetrically connected to both sides of the sliding plate; a driven gear, connected to the rotating shaft of the rotating clamp rod, and the driven gear meshes with the driving rack; and a sixth electric push rod, mounted on the mounting bracket, with the telescopic rod of the sixth electric push rod connected to the sliding plate.

[0015] The beneficial effects of this invention are as follows: 1. The diameter of the vertical tube in this invention is smaller than the diameter of the circular hole, which allows the vertical tube to easily pass through the circular holes on the cantilever and the inclined plate in sequence. Then, the first electric push rod drives the lifting rod and the conical block to rise. By utilizing the contact and cooperation between the conical block and the inclined surface on the sliding rod, multiple sliding rods can move outward to contact the inner wall of the circular hole and automatically adjust their positions to ensure the coaxiality between the cantilever and the inclined plate, thereby improving the welding accuracy. Compared with the traditional method of manually inserting cylinders, this design can not only reduce labor intensity but also improve work efficiency.

[0016] 2. This invention, through the cooperation of a conical platform, connecting rod, connecting disc, spring sheet, and limiting cover, enables the entire vertical tube to be finely adjusted horizontally within a certain range, thereby compensating for the positional deviation between the vertical tube and the round hole. This flexible design allows the vertical tube to adapt to the positional deviation, ensuring precise alignment between parts without displacement of the cantilever, and ensuring that the vertical tube can quickly and accurately pass through the round hole on the cantilever and inclined plate in sequence, thus improving work efficiency.

[0017] 3. This invention enables automatic conveying of the cantilever through the cooperation of the conveyor and the limiting plate, while the feeding component can automatically place the inclined plate. These automated steps reduce the need for manual intervention. In addition, the use of welding robots enables the automation of a series of processes from parts supply to the final welded product. This not only significantly improves the speed of a single operation, but also greatly improves the overall efficiency and stability of large-scale production. At the same time, the rotating clamp can hold the cantilever during the welding process, further ensuring the stable progress of the welding work. Attached Figure Description

[0033] like Figure 1 , Figure 6 and Figure 7As shown, the lifting assembly includes a fixed frame 9, a second electric push rod 10, a conical platform 11, and a movable connecting mechanism. The fixed frame 9 is connected to the lower front side of the support frame 1. The second electric push rod 10 is mounted on the fixed frame 9.

The limit cover 15 is used to limit the connecting plate 13. A through hole 1501 is opened on the top of the limit cover 15, and the connecting rod 12 passes through the through hole 1501.

[0034] like Figure 8 As shown, the conveying assembly includes a conveyor 16, a limiting plate 17, and a stabilizing mechanism. The conveyor 16 is installed in the middle of the support frame 1. The conveyor belt of the conveyor 16 is evenly spaced around the circumference of multiple sets of limiting plates 17, with two limiting plates 17 in each set. The conveyor 16 is provided with a stabilizing mechanism for stabilizing the cantilever 001 conveyed on the conveyor 16. The stabilizing mechanism includes a support plate 18 and a bar magnet 19. The support plate 18 is connected to the rear side of the top of the frame of the conveyor 16, and the bar magnet 19 is connected to the front side of the support plate 18.

[0035] like Figure 1 , Figure 9 and Figure 10As shown, the feeding assembly includes a translation mechanism, a lifting frame 20, limit rods 21, vertical plates 22, a third electric push rod 23, a mounting plate 24, a square magnet 25, and a fourth electric push rod 26. The support frame 1 is equipped with a translation mechanism, on which the lifting frame 20 is slidably mounted. The translation mechanism drives the lifting frame 20 to move horizontally. Multiple limit rods 21 are spaced apart on the lifting frame 20, and the distribution shape of the limit rods 21 matches the outer edge shape of the inclined plate 002. Vertical plates 22 are symmetrically connected to the bottom of the lifting frame 20, and a third electric push rod 23 is mounted on each of the two vertical plates 22. The telescopic rods of the two third electric push rods 23 are... The system is connected to mounting plates 24, each with a square magnet 25. The translation mechanism is also equipped with a fourth electric push rod 26, and the telescopic rod of the fourth electric push rod 26 is connected to the lifting frame 20. The translation mechanism includes a connecting frame 27, a sliding frame 28, and a fifth electric push rod 29. The connecting frame 27 is connected to the upper rear side of the support frame 1, and the sliding frame 28 is slidably connected to the lower part of the connecting frame 27. The lifting frame 20 is slidably connected to the front end of the sliding frame 28. The fourth electric push rod 26 is fixedly connected to the front of the sliding frame 28. The fifth electric push rod 29 is installed at the lower part of the connecting frame 27, and the telescopic rod of the fifth electric push rod 29 is connected to the sliding frame 28.

[0036] like Figure 1 and Figure 11 As shown, it also includes a mounting frame 30, a rotating clamp 31, and a rotating assembly. The mounting frame 30 is connected to the lower front side of the support frame 1. The rotating clamp 31 is symmetrically rotatably connected to the upper part of the mounting frame 30. The mounting frame 30 is provided with a rotating assembly for driving the rotating clamp 31 to rotate and clamp the cantilever 001. The rotating assembly includes a sliding plate 32, a driving rack 33, a driven gear 34, and a sixth electric push rod 35. The sliding plate 32 is slidably connected to the upper middle part of the mounting frame 30. The driving rack 33 is connected to the lower part of both sides of the sliding plate 32. The driven gear 34 is connected to the rotation shaft of both rotating clamps 31, and the driven gear 34 meshes with the driving rack 33. The sixth electric push rod 35 is installed in the middle of the top of the mounting frame 30, and the telescopic rod of the sixth electric push rod 35 is connected to the sliding plate 32.

[0037] When welding cantilever 001 and tie plate 002 is required, firstly, an appropriate number of tie plates 002 are stacked between multiple limiting rods 21. Square magnets 25 can clamp the lowermost tie plates 002 and attract them through magnetic force (e.g., ...). Figure 13As shown), to prevent the inclined pull plates 002 stacked between the limiting rods 21 from falling; then start the conveyor 16, which will drive the limiting plate 17 to rotate intermittently. At this time, the cantilever 001 can be placed between the two limiting plates 17 in the same group, and the rear side of the cantilever 001 should contact the bar magnet 19. The limiting plate 17 can limit the cantilever 001, preventing the cantilever 001 from moving in the left and right directions. The limiting plate 17 can also drive the cantilever 001 to move intermittently to the right. Due to the extension of the bar magnet 19, The extension direction is parallel to the movement direction of the cantilever 001, so the bar magnet 19 can stabilize the position of the cantilever 001 through magnetic force, preventing the cantilever 001 from moving in the front-to-back direction, without affecting the movement of the cantilever 001. When the cantilever 001 moves above the vertical hole 101, the cantilever 001 will stop moving. At this time, the sixth electric push rod 35 drives the sliding plate 32 to move forward. The sliding plate 32 drives the driving rack 33 to move forward. The driving rack 33 drives the driven gear 34 to rotate. The driven gear 34 drives the rotating gear to rotate. The movable clamping rod 31 rotates backward so that the two rotating clamping rods 31 cooperate to clamp the cantilever 001, thereby fixing the position of the cantilever 001; then, the fifth electric push rod 29 drives the sliding frame 28 to move forward, the sliding frame 28 drives the lifting frame 20 and the limiting rod 21 to move forward, thereby driving the inclined plate 002 to move forward, so that the inclined plate 002 moves directly above the cantilever 001; then, the third electric push rod 23 drives the mounting plates 24 on the left and right sides to move to the side away from each other, the mounting plates 24 can drive the left... The square magnets 25 on both right sides move away from each other, causing them to detach from the inclined plate 002. At this point, the inclined plate 002 will fall downwards due to gravity, with the lowest inclined plate 002 contacting the top of the cantilever 001. Under the limiting action of the limiting rod 21, the inclined plate 002 can make minor adjustments to its position at the top of the cantilever 001, but it will not slip off the top of the cantilever 001. Furthermore, the height of the inclined plate 002 at the top of the cantilever 001 is lower than the height of the bottom of the square magnet 25 (e.g., ...). Figure 13As shown), so that the square magnet 25 can no longer clamp the inclined plate 002 located at the top of the cantilever 001; then the second electric push rod 10 drives the conical platform 11 to move upward, the conical platform 11 can drive the connecting plate 13, connecting rod 12, mounting cylinder 3 and vertical tube 4 to move upward, so that the vertical tube 4 can pass through the round hole 003 on the cantilever 001 and the inclined plate 002 in sequence. Since the diameter of the vertical tube 4 is smaller than the diameter of the round hole 003, the upper end of the vertical tube 4 can easily pass through the round hole 003. At the same time, the upper end of the vertical tube 4 is an arc surface, and the connecting rod 12 can move flexibly in the through hole 1501, so that the vertical tube 4 can move flexibly within a certain range to adjust its position. The spring piece 14 can adaptably deform, even if the position of the vertical tube 4 and the round hole 003 is in the vertical direction. With a slight deviation, the vertical tube 4 can easily pass through the circular hole 003; then, the first electric push rod 5 drives the lifting rod 6 and the conical block 601 to move upward. Through the cooperation of the conical block 601 and the inclined plane 702, the conical block 601 will squeeze multiple sliding rods 7 to move to the side away from each other, and the ring spring 8 will be stretched. When the sliding rod 7 contacts the inner wall of the circular hole 003, the sliding rod 7 will push the inclined plate 002 to move, finely adjusting the position of the inclined plate 002. At the same time, since the cantilever 001 is clamped and fixed by the rotating clamp 31, the cantilever 001 remains stationary. The reaction force of the sliding rod 7 pushing the cantilever 001 will be transmitted to the spring piece 14 through the vertical tube 4, forcing the spring piece 14 to undergo elastic deformation, thereby causing the vertical tube 4 to float slightly in the horizontal plane until... The axes of the circular holes 003 on the cantilever 001 and the inclined plate 002 are perfectly aligned with the axis of the vertical tube 4. During this process, the flexible design of the spring piece 14 allows the vertical tube 4 to adapt to positional deviations without displacement of the cantilever 001, thus ensuring the coaxiality of the circular holes 003 on the cantilever 001 and the inclined plate 002. At this time, the welding robot 2 can perform spot welding on the cantilever 001 and the inclined plate 002. Since there is a gap between the two adjacent limit rods 21, there is enough operating space for the welding robot 2. After the spot welding is completed, the mounting plates 24 on the left and right sides are driven by the third electric push rod 23 to move towards each other. The mounting plates 24 can drive the square magnets 25 on the left and right sides to move towards each other, so that the square magnets 25 clamp the remaining inclined plates. The inclined plate 002 is magnetically attracted and then driven upward by the fourth electric push rod 26. The lifting frame 20 moves upward, causing the limiting rod 21, mounting plate 24, and square magnet 25 to move away from the inclined plate 002 welded to the top of the cantilever 001. Then, the sliding frame 28 moves backward to reset via the fifth electric push rod 29. The sliding frame 28 moves backward to reset the lifting frame 20 and the limiting rod 21. The limiting rod 21 moves the remaining inclined plates 002 backward to reset. Then, the lifting frame 20 moves downward to reset via the fourth electric push rod 26. The lifting frame 20 moves downward to reset the limiting rod 21, mounting plate 24, and square magnet 25. At this point, the inclined plate 002 can be completely welded to the top of the cantilever 001 by the welding robot 2.After welding, the first electric push rod 5 drives the lifting rod 6 and the conical block 601 to move downwards, causing the conical block 601 to disengage from the inclined plane 702. At this time, the ring spring 8 returns to its original state, driving multiple sliding rods 7 to move closer to each other and reset. Then, the second electric push rod 10 drives the conical platform 11 to move downwards and reset. The conical platform 11 can drive the connecting plate 13, connecting rod 12, mounting cylinder 3, and vertical pipe 4 to move downwards and reset, causing the vertical pipe 4 to disengage from the round hole 003 on the cantilever 001 and the inclined plate 002. At this time, the spring piece 14 returns to its original state, driving the vertical pipe 4 to move horizontally and reset. Then, the conveyor 16 can transport the welded inclined plate 002 and cantilever 001 to the right for discharge, and the conveyor 16 can transport the next cantilever 001 to the top of the vertical hole 101. Repeating the above operation can automatically weld the inclined plate 002 to the top of the cantilever 001.
