Description

Technical Field

[0001] This invention relates to the field of automotive chassis parts welding technology, and in particular to an automatic tilting operation device for subframe welding. Background Technology

[0002] With the popularization of lightweight and modular design concepts in automobiles, the subframe, as a key structural component supporting the front and rear axles and suspension system, is facing increasingly higher requirements in terms of structural complexity and welding quality. Currently, subframes are usually assembled by welding multiple stamped steel plates or tubing, resulting in a large number of welds with complex spatial orientation, generally requiring double-sided or multi-angle welding.

[0003] In the existing subframe welding production process, manual flipping is labor-intensive and poses safety hazards: a typical passenger car subframe is about 1m × 1.2m in size and weighs between 20-30kg, while commercial vehicle subframes are even heavier. Without automated equipment, on-site operators must manually move and flip the workpieces between welding processes to complete back or side welds. This work mode not only leads to significantly higher labor intensity for workers, but also poses safety risks of burns, cuts, and injuries due to the presence of high-temperature weld slag and sharp workpiece edges.

[0004] However, ordinary automatic tilting equipment for subframe welding often has some problems in daily use. With the development of technology, technicians in related fields have also made a lot of optimizations to automatic tilting equipment for subframe welding to solve some of the problems that different consumer groups care about. For a more accurate comparison, Chinese patent with publication number CN216177848U discloses a subframe positioning and assembly fixture. In view of the problem that some existing welding fixtures for subframes have simple structures and functions, and may require multiple clamping and tilting of the subframe during the welding process, which affects the processing efficiency, the following solution is proposed. It includes an operating table, the top of which has a slide groove, and two symmetrically distributed sliders are slidably arranged in the slide groove. A double-threaded screw is rotatably arranged in the slide groove, and the thread of the double-threaded screw passes through the two sliders. The top of each slider is fixedly equipped with a support seat with the same structure, and the top of each support seat is fixedly equipped with an adjusting plate. The two adjusting plates are rotatably connected by a shaft column on the side that is close to each other. The aforementioned existing technology has a novel structure, enabling the subframe welding fixture to be quickly flipped and adjusted during use, thus improving processing efficiency and practicality, and is suitable for widespread application.

[0005] However, the aforementioned subframe positioning and assembly fixtures have some shortcomings in actual use: 1. The above-mentioned subframe positioning and assembly fixture uses the cooperation of the axle column, adjusting plate, adjusting and locking components and clamping components to fix the subframe to be processed. However, when fixing the subframe to be processed, manual adjustment is required according to the model of the subframe, which results in low processing efficiency.

[0006] 2. The above-mentioned subframe positioning and assembly fixture rotates the adjustment knob to drive the adjustment rod to rotate, causing the pawl to disengage from the teeth of the ratchet disc, which can push the support plate on that side to flip. When it is necessary to adjust the welding angle of the subframe, the support plate needs to be manually pushed to flip, which leads to inaccurate flipping angle of the support plate and thus affects the processing quality.

[0007] Therefore, based on the above-stated viewpoints, there is still room for improvement in existing automated tilting equipment for subframe welding. Summary of the Invention

[0008] To address the aforementioned problems, this invention provides an automatic tilting operation device for subframe welding, comprising a processing table, support legs at the four corners of the bottom of the processing table, a hydraulic rod running through the center of the processing table, a placement platform at the top of the telescopic end of the hydraulic rod, folding plates symmetrically arranged between the placement platform and the processing table, clamping mechanisms symmetrically arranged on the top of the processing table and on both sides of the placement platform, and a tilting mechanism on one side of the placement platform.

[0012] Preferably, the execution unit further includes pulleys disposed on the top of the processing table, the placement table and the moving block are connected by steel wire ropes via the pulleys, and spring rods with telescopic ends that abut against the bottom of the lifting block are symmetrically disposed at the bottom of the placement table.

[0013] Preferably, the flipping mechanism includes a connecting rod disposed on the side of the rotating shaft away from the square block and passing through the strip plate, a synchronization ring is sleeved on the connecting rod, and multiple flipping plates are evenly arranged along the circumference of the synchronization ring.

[0014] Preferably, the flipping mechanism further includes a welding plate disposed on one side of the placement platform, a reciprocating screw symmetrically rotatably disposed within the welding plate, an electric slider fitted on the reciprocating screw, a welding arm disposed on the top of the electric slider, and a drive unit disposed on the reciprocating screw.

[0015] Preferably, the drive unit includes a drive ring sleeved on the side of the reciprocating lead screw away from the electric slider, a drive plate is circumferentially arranged on the outer wall of the drive ring, an arc-shaped triangular block I is arranged on the reciprocating lead screw, and an arc-shaped triangular block II is arranged on the inner wall of the drive ring, which abuts against the arc-shaped triangular block I.

[0016] Preferably, the drive unit further includes a limiting ring rotatably sleeved on the reciprocating lead screw, the drive ring being provided with multiple top plates, and a spring being provided between the top plates and the limiting ring.

[0017] Preferably, the top of the placement platform and the bottom of the arc-shaped clamp are provided with anti-slip pads.

[0019] Second, this invention achieves misaligned clamping by using the cooperation of the contact platform and the arc-shaped clamping plate to clamp the subframe.

Furthermore, the cooperation of arc-shaped triangular block one and arc-shaped triangular block two enables the fixed block to rotate in one direction and prevents the fixed block from rotating in both directions.

[0031] The following is in conjunction with the appendix Figures 1 to 8 The embodiments of the present invention will be described in detail, but the present invention may be implemented in many different ways as defined and covered by the claims.

[0032] This application discloses an automatic tilting operation device for subframe welding. It is described that this application is mainly used in the subframe welding process. In terms of technical effect, it can clamp subframes of different sizes and types, thereby improving the practicality of the device. In particular, it can handle the protrusions at the clamping position of the subframe by using staggered clamping. Furthermore, this application can also automatically drive the subframe to rotate after the subframe is clamped, so that the subframe can be rotated to a suitable welding position.

[0033] Example 1: Reference Figure 1 As shown, an automatic tilting operation device for welding subframes includes a processing table 1, support legs 10, hydraulic rods 11, a placement platform 12, folding plates 13, clamping mechanisms 2, and tilting mechanisms 3. Support legs 10 are located at the four corners of the bottom of the processing table 1. A hydraulic rod 11 is threaded through the center of the processing table 1. The placement platform 12 is located at the top of the telescopic end of the hydraulic rod 11. When the hydraulic rod 11 telescopically moves, it can move the placement platform 12 together. The placement platform 12 is used to place the subframe. Folding plates 13 are symmetrically arranged between the placement platform 12 and the processing table 1. When the placement platform 12 rises, the folding plates 13 unfold, making the placement platform 12 more stable and preventing the subframe from falling. Clamping mechanisms 2 are symmetrically arranged on the top of the processing table 1 and on both sides of the placement platform 12. The clamping mechanisms 2 are used to fix the subframe and prevent it from moving during welding. A tilting mechanism 3 is located on one side of the placement platform 12. The tilting mechanism 3 is used to rotate the subframe, facilitating welding of the subframe.

[0034] In the specific implementation process, the subframe is placed on the placement platform 12, and then the placement platform 12 and the subframe are lifted by the hydraulic rod 11. Then the subframe is fixed by the clamping mechanism 2 to prevent the subframe from moving during welding. Then the subframe is rotated by the flipping mechanism 3 to facilitate welding of the subframe.

[0035] Reference Figure 2As shown, this is the clamping mechanism 2 in this application; specifically, the clamping mechanism 2 includes a moving block 20, a moving groove 200, a first spring 201, a strip plate 21, a lifting block 22, a rotating shaft 23, a square block 24, a fixed block 25, an adjusting block 26, an adjusting groove 27, a second spring 28, and an execution unit 29. A moving block 20 is slidably disposed on the top of the processing table 1, and the moving block 20 can slide under the constraint of the processing table 1; a moving groove 200 is provided on the top of the processing table 1 for the moving block 20 to move, and a first spring 201 is disposed between the moving block 20 and the moving groove 200, which can always provide the moving block 20 with a pushing force away from the placement table 12; a strip plate 21 is disposed on the top of the moving block 20, and the moving block 20 can drive the strip plate 21 to move together when it moves; a lifting block 22 is slidably disposed inside the strip plate 21, and the lifting block 22 can slide under the constraint of the strip plate 21; the lifting block 22... A rotating shaft 23 is rotatably mounted in the middle of the lifting block 22. When the lifting block 22 moves, it can drive the rotating shaft 23 to move together, and the rotating shaft 23 can rotate under the restriction of the lifting block 22. A square block 24 is provided on the side of the rotating shaft 23 near the placement platform 12. When the rotating shaft 23 moves, it can drive the square block 24 to move together. A fixed block 25 is provided on the side of the square block 24 away from the rotating shaft 23. When the square block 24 moves, it can drive the fixed block 25 to move together. An adjusting block 26 is slidably mounted in the fixed block 25. The adjusting block 26 can slide under the restriction of the fixed block 25. An adjusting groove 27 is provided on the fixed block 25 for the adjusting block 26 to move. A spring 28 is provided between the adjusting groove 27 and the adjusting block 26. The spring 28 can always provide an upward thrust to the adjusting block 26. An execution unit 29 is provided in the fixed block 25 and the adjusting block 26. The execution unit 29 is used to clamp the subframe.

[0036] In the specific implementation process, when the placement platform 12 is raised, the moving block 20 can move together with the processing platform 1 when it moves under the restriction of the processing platform 1. When the moving block 20 moves, it can move together with the strip plate 21. At the same time, when the placement platform 12 is raised, it can also move the lifting block 22 upward under the restriction of the strip plate 21. When the lifting block 22 moves, it can move together with the rotating shaft 23. When the rotating shaft 23 moves, it can move together with the square block 24. When the square block 24 moves, it can move together with the fixed block 25, so that the square block 24 and the fixed block 25 rise synchronously with the placement platform 12, and the adjusting block 26 can slide under the restriction of the fixed block 25. When the adjusting block 26 moves, it clamps the subframe through the execution unit 29.

[0037] Reference Figure 3As shown, this is the execution unit 29 in this application; specifically, the execution unit 29 includes an arc-shaped clamping plate 290, a rotating plate 291, a contact platform 292, a push plate 293, and an extension plate 294. The arc-shaped clamping plate 290 is provided on the side of the adjusting block 26 away from the square block 24. When the adjusting block 26 moves, it can drive the arc-shaped clamping plate 290 to move together. The rotating plate 291 is rotatably provided inside the square block 24, which contacts the adjusting block 26. When the rotating plate 291 rotates, it will push the adjusting block 26 to move. A contact platform 292 is provided on the side of the fixed block 25 away from the square block 24. When the fixed block 25 moves, it can drive the contact platform 292 to move together. A push plate 293 is slidably provided on the top of the contact platform 292. The push plate 293 can slide under the restriction of the contact platform 292. An extension plate 294 is provided on one side of the push plate 293, which abuts against the rotating plate 291. When the push plate 293 moves, it can drive the extension plate 294 to move together. When the extension plate 294 moves, it can push the rotating plate 291 to rotate.

[0038] In the specific implementation process, when the moving block 20 moves the fixed block 25, it can move the contact platform 292 together, so that the subframe moves to the top of the contact platform 292. During this process, the subframe will also contact the push plate 293 and push the push plate 293 to move towards the fixed block 25. When the push plate 293 moves, it can move the extension plate 294 together. When the extension plate 294 moves, it can push the rotating plate 291 to rotate. When the rotating plate 291 rotates, it will push the adjusting block 26 to move downward. When the adjusting block 26 moves, it will move the arc-shaped clamping plate 290 together. The subframe is clamped by the cooperation of the contact platform 292 and the arc-shaped clamping plate 290. Moreover, this staggered clamping can avoid the disadvantage that the straight plate has only a small contact area with the subframe when clamping the arc edge of the subframe in the traditional straight plate, resulting in a loose clamping.

[0039] Reference Figure 4 As shown, this is the execution unit 29 in this application; specifically, the execution unit 29 also includes a pulley 295, a wire rope 296, and a spring rod 297. The top of the processing table 1 is provided with a pulley 295. The placement table 12 and the moving block 20 are connected by the pulley 295 and the wire rope 296. When the placement table 12 moves upward, the moving block 20 is driven to move towards the placement table 12 through the wire rope 296. The bottom of the placement table 12 is symmetrically provided with spring rods 297 whose telescopic ends abut against the bottom of the lifting block 22. When the placement table 12 moves, it will drive the spring rods 297 to move together, and the movement of the spring rods 297 will drive the lifting block 22 to move together.

[0040] In the specific implementation process, when the placement platform 12 moves upward, the moving block 20 moves towards the placement platform 12 via the steel wire rope 296, so that the subframes of different sizes and specifications can move to the top of the contact platform 292; and when the placement platform 12 moves upward, it can drive the spring rod 297 to move together, and when the spring rod 297 moves, it can drive the lifting block 22 to move together, so that the distance between the lifting block 22 and the contact platform 292 and the placement platform 12 remains unchanged.

[0041] Reference Figure 5 As shown, this is the flipping mechanism 3 in this application; specifically, the flipping mechanism 3 includes a connecting rod 30, a synchronous ring 31, a flipping plate 32, a welding plate 33, a reciprocating screw 34, an electric slider 35, a welding arm 36, and a drive unit 37. The rotating shaft 23 is located away from the square block 24 and passes through the strip plate 21, and the connecting rod 30 is provided thereon. When the connecting rod 30 rotates, it can drive the rotating shaft 23 to rotate together. The synchronous ring 31 is sleeved on the connecting rod 30. When the synchronous ring 31 rotates, it can drive the connecting rod 30 to rotate together. Multiple flipping plates 32 are evenly arranged around the synchronous ring 31. The flipping plates 32 can drive the synchronous ring to rotate together. 31. Rotation; A welding plate 33 is provided on one side of the placement platform 12, which can move the welding plate 33 together when the placement platform 12 is raised and lowered; A reciprocating screw 34 is symmetrically rotated inside the welding plate 33, which can rotate under the restriction of the welding plate 33; An electric slider 35 is fitted on the reciprocating screw 34, which can drive the reciprocating screw 34 to rotate when the electric slider 35 moves; A welding arm 36 is provided on the top of the electric slider 35, which is used to weld the subframe; A drive unit 37 is provided on the reciprocating screw 34, which is used to drive the tilting plate 32 to rotate when the reciprocating screw 34 rotates.

[0042] In the specific implementation process, when the placement platform 12 is raised and lowered, it can drive the welding plate 33 to move together. When the welding plate 33 moves, it will drive the electric slider 35 and the welding arm 36 to move together. The subframe is welded through the welding arm 36. After the welding of a certain angle is completed, the electric slider 35 will drive the welding arm 36 to move. When the electric slider 35 moves, it will drive the reciprocating screw 34 to rotate.

[0043] Reference Figure 6 and Figure 7As shown, this is the drive unit 37 in this application; specifically, the drive unit 37 includes a drive ring 370, a drive plate 371, an arc-shaped triangular block 372, an arc-shaped triangular block 373, a limiting ring 374, a top plate 375, and a spring 376. The reciprocating screw 34 is fitted with a drive ring 370 on the side away from the electric slider 35. The drive plate 371 is circumferentially arranged on the outer wall of the drive ring 370. When the drive ring 370 rotates, it will drive the drive plate 371 to rotate together. When the drive plate 371 rotates, it will abut against the flip plate 32, thereby driving the flip plate 32 to rotate. The reciprocating screw 34 is provided with an arc-shaped triangular block 370. 72. When the reciprocating screw 34 rotates, it will drive the arc-shaped triangular block 372 to rotate together; the inner wall of the drive ring 370 is provided with an arc-shaped triangular block 373 that abuts against the arc-shaped triangular block 372. When the arc-shaped triangular block 372 rotates, it will abut against the arc-shaped triangular block 373; a limiting ring 374 is rotatably sleeved on the reciprocating screw 34. The limiting ring 374 can rotate under the restriction of the reciprocating screw 34; multiple top plates 375 are provided on the drive ring 370. A spring 376 is provided between the top plate 375 and the limiting ring 374. The spring 376 can always provide the top plate 375 with a pulling force towards the reciprocating screw 34.

[0044] In the specific implementation process, when the electric slider 35 moves, it will drive the reciprocating screw 34 to rotate. When the reciprocating screw 34 rotates, it will drive the arc-shaped triangular block 372 to move together. When the arc-shaped triangular block 372 rotates, it will abut against the arc-shaped triangular block 373. When the right-angled side of the arc-shaped triangular block 372 abuts against the right-angled side of the arc-shaped triangular block 373, it can drive the drive ring 370 to rotate together. When the drive ring 370 rotates, it will drive the drive plate 371 to rotate together. When the drive plate 371 rotates, it will abut against the flipping plate 373. 2. When the arc-shaped edge of arc-shaped triangular block 1 372 contacts the arc-shaped edge of arc-shaped triangular block 2 373, arc-shaped triangular block 1 372 will push arc-shaped triangular block 2 373 to move away from the reciprocating screw 34, so as not to drive the drive ring 370 and drive plate 371 to rotate, preventing the drive plate 371 from rotating when the electric slider 35 drives the welding arm 36 to reset. After moving, arc-shaped triangular block 2 373 will reset under the action of spring 3 376.

[0045] Example 2: Reference Figure 8 As shown, based on Embodiment 1, to prevent the subframe from falling off the placement platform 12 and the contact platform 292 and to further stabilize the clamping of the subframe, in a specific embodiment of this solution, anti-slip pads 4 are provided on the top of the placement platform 12 and the bottom of the arc-shaped clamping plate 290. The anti-slip pads 4 are used to increase the friction between the subframe and the placement platform 12 and the arc-shaped clamping plate 290.

[0046] During operation: First step: Place the subframe on the placement platform 12, and then lift the placement platform 12 and the subframe by means of the hydraulic rod 11. When the placement platform 12 moves upward, the moving block 20 moves towards the placement platform 12 by means of the wire rope 296, so that the subframe moves to the top of the contact platform 292; and when the placement platform 12 moves upward, it can drive the spring rod 297 to move together, and when the spring rod 297 moves, it can drive the lifting block 22 to move together.

[0047] Step 2: When the placement table 12 is raised, the moving block 20 moves under the restriction of the processing table 1, which can drive the moving block 20 to move together. When the moving block 20 moves, it can drive the strip plate 21 to move together. At the same time, when the placement table 12 is raised, it can also drive the lifting block 22 to move upward under the restriction of the strip plate 21. When the lifting block 22 moves, it can drive the rotating shaft 23 to move together. When the rotating shaft 23 moves, it can drive the square block 24 to move together. When the square block 24 moves, it can drive the fixed block 25 to move together, so that the square block 24 and the fixed block 25 rise synchronously with the placement table 12, and the adjusting block 26 can slide under the restriction of the fixed block 25.

[0048] Step 3: When the moving block 20 moves the fixed block 25, it can move the contact platform 292 together, so that the subframe moves to the top of the contact platform 292. During this process, the subframe will also contact the push plate 293 and push the push plate 293 to move towards the fixed block 25. When the push plate 293 moves, it can move the extension plate 294 together. When the extension plate 294 moves, it can push the rotating plate 291 to rotate. When the rotating plate 291 rotates, it will push the adjusting block 26 to move downward. When the adjusting block 26 moves, it will move the arc-shaped clamping plate 290 together. The subframe is clamped by the cooperation of the contact platform 292 and the arc-shaped clamping plate 290. This staggered clamping can avoid the disadvantage of the traditional straight plate clamping the arc edge of the subframe having only a small contact area with the subframe, resulting in a loose clamping.

[0049] Step 4: When the placement platform 12 is raised and lowered, it moves the welding plate 33 along with it. The movement of the welding plate 33 then moves the electric slider 35 and the welding arm 36 together. The welding arm 36 then welds the subframe. During this process, the movement of the electric slider 35 drives the reciprocating screw 34 to rotate. The rotation of the reciprocating screw 34 drives the arc-shaped triangular block 372 to move together. When the arc-shaped triangular block 372 rotates, it will contact the arc-shaped triangular block 373. When the right-angled side of the arc-shaped triangular block 372 contacts the right-angled side of the arc-shaped triangular block 373, it can drive the drive... The rotating ring 370 rotates together with the driving ring 370. When the driving ring 370 rotates, it will drive the driving plate 371 to rotate together. When the driving plate 371 rotates, it will contact the flipping plate 32, thereby driving the flipping plate 32 to rotate. When the arc-shaped edge of the first arc-shaped triangular block 372 contacts the arc-shaped edge of the second arc-shaped triangular block 373, the first arc-shaped triangular block 372 will push the second arc-shaped triangular block 373 to move away from the reciprocating screw 34, so that the driving ring 370 and the driving plate 371 will not rotate, thus preventing the electric slider 35 from driving the welding arm 36 to reset and causing the driving plate 371 to rotate.
