[0002] The frame is particularly important in automobile production and processing. When welding the automobile, the frame needs to be turned over to facilitate welding for the workers.

[0003] The utility model patent with announcement number CN214684980U proposes a new type of automatic turning tool for welding a rail passenger car frame, including a base, two side columns are fixedly connected to the top surface of the base, and cross bars are connected to the inside of the two side columns. A clamping mechanism is arranged on the outside of the cross bar, and the clamping mechanism includes a movable clamping block, the movable clamping block is located on the outside of the cross bar, and the inner side of the movable clamping block is threadedly connected to the cross bar, a thread groove is provided inside the movable clamping block, a threaded rod is threadedly connected to the inner side of the thread groove, both ends of the threaded rod are located on the outside of the movable clamping block, and a second limit block is fixedly connected to the surface of one end of the threaded rod, and the second limit block is located on the outside of the movable clamping block.

[0004] Although the above-mentioned tooling can realize automatic flipping of the automobile frame, it cannot limit the position of the flipped automobile frame. During the welding process, the automobile frame may be rotated by the user, and there is a risk of damage to the welded parts. At the same time, the safety of the operator cannot be effectively guaranteed. Utility Model Content

[0005] The purpose of the utility model is to solve or at least alleviate the problem that the existing tooling is unable to limit the position of the automobile frame after flipping, and the automobile frame may be forced to rotate during the welding process, which may cause the risk of damage to the welded parts.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The front skeleton welding flip tooling comprises a bottom plate with brackets fixedly connected to the upper surfaces of both ends, a support beam is slidably connected between the two brackets, a clamping assembly is arranged on the support beam, sliding holes are opened on the two brackets, connecting shafts extending into the inner cavity of the sliding holes are fixedly connected to the two ends of the support beam, a connecting ring is sleeved on the connecting shaft, an electric telescopic rod whose output end is fixedly connected to the lower surface of the connecting ring is fixedly connected in the inner cavity of the sliding hole, a group of limit plates are arranged on the adjacent sides of the two brackets, and the adjacent sides of the two limit plates in each group are respectively in sliding contact with the two sides of the support beam, and when the electric telescopic rod is in a retracted state, the upper surface height of the support beam is flush with the top height of the limit plate, and the connecting shaft at one end of the support beam and the bracket close to the connecting shaft are equipped with mutually cooperating flip assemblies.

[0008] By adopting the above technical solution, when using, the user first clamps the car frame on the support beam through the clamping arm, and then welds the car frame. When the car frame needs to be flipped during the welding process, the electric telescopic rod can be started to extend, and the connecting shaft in the inner cavity of the connecting ring can be pushed up along the sliding hole until the driven gear installed on the connecting shaft is meshed with the driving gear installed on the output end of the servo motor. At this time, the support beam slides out from the top of the limit plate, and the user can start the servo motor, and drive the support beam to rotate between the two brackets through the driving gear, the driven gear and the connecting shaft, thereby driving the car frame clamped and fixed on the support beam to flip. After the car frame is adjusted and flipped to a suitable angle, the user starts the electric telescopic rod to contract, and pulls the support beam down to between the two limit plates in each group through the connecting ring. The support beam is clamped and fixed from both sides by the limit plates to prevent the car frame on the support beam from driving the support beam to rotate after being subjected to force, and the existing tooling is unable to limit the flipped car frame as much as possible. The user's car frame may be subjected to force and rotate during the welding process, and there is a risk of damage to the welded parts.

[0009] Optionally, the bottom plate is a rectangular plate-shaped structure, and fixing holes for fixing the bottom plate are provided at the four corners of the bottom plate.

[0010] By adopting the above technical solution, a base plate is provided to lower the center of gravity of the entire device and improve the stability of the entire device. Fixing holes are provided to facilitate users to fix the base plate to the ground or an external rack through the fixing holes.

[0011] Optionally, the clamping assembly includes two slip rings sleeved on the support beam, and symmetrically arranged clamping arms are fixedly connected to the outer walls on both sides of the two slip rings. A limit bolt threadedly connected to the slip ring is passed through the top wall of the slip ring, and one end of the limit bolt located in the inner cavity of the slip ring abuts against the support beam.

[0012] By adopting the above technical solution, when using, the user can place the car frame on the support beam between the two slip rings, then slide the two slip rings toward each other, clamp the car frame through the clamping arms set on both sides of the slip rings, and then screw the limit bolts to fix the slip rings to achieve the clamping work of the car frame.

[0013] Optionally, a screw rod threadedly connected to the clamping arm is provided on one end of the clamping arm away from the slip ring, and a rubber pad is installed on one end of the screw rod close to the middle section of the support beam.

[0014] By adopting the above technical solution, after the user clamps the car frame through the clamping arm, the screw can be screwed to drive the rubber pad to move toward the car frame, and the clamping force can be fine-tuned to improve the stability of the clamping of the car frame.

[0015] Optionally, a bearing is provided at the connecting end of the screw rod and the rubber pad, the inner ring of the bearing is fixedly connected to the screw rod, and the outer ring of the bearing is embedded in the rubber pad and fixedly connected to the rubber pad.

[0016] By adopting the above technical solution, a bearing is set to rotatably connect the screw rod and the rubber pad, so as to avoid the problem that the rubber pad that fits the car frame rotates synchronously when the user rotates the screw rod, causing friction between the rotation of the rubber pad and the car frame, which may cause wear of the car frame.

[0017] Optionally, the flipping assembly includes a driven gear fixedly connected to one end of one connecting shaft away from the support beam, and the flipping assembly also includes a servo motor fixedly connected to the bracket above the driven gear, and a driving gear fixedly connected to the output end of the servo motor.

[0018] By adopting the above technical solution, when the driven gear and the driving gear are meshed with each other, the user can start the servo motor to drive the driving gear to rotate, thereby driving the support beam to rotate through the driven gear and the connecting shaft, thereby realizing the flipping of the car frame clamped and fixed on the support beam.

[0019] Optionally, a mounting plate is fixedly connected to the servo motor, and bolts are passed through the mounting plate. The bolts penetrate the mounting plate and are screwed to the bracket.

[0020] By adopting the above technical solution, a mounting plate is provided to improve the stability of the servo motor installation, and a screw connection method is adopted, which not only ensures a stable connection, but also facilitates the user to install and disassemble the servo motor.

[0021] Optionally, when the electric telescopic rod is in an extended state, the driven gear moves up to mesh with the driving gear.

[0022] By adopting the above technical solution, the user can adjust the height of the support beam through the electric telescopic rod to achieve flipping or fixing the support beam.

[0023] In summary, the beneficial effects of this application are as follows:

[0024] The present application achieves this by coordinating the structures including the connecting shaft, the connecting ring, the electric telescopic rod and the limit plate. When the car frame is adjusted and flipped to a suitable angle, the user activates the contraction of the electric telescopic rod, and pulls the support beam down to between the two limit plates in each group through the connecting ring. The support beam is clamped and fixed from both sides by the limit plates to prevent the car frame on the support beam from rotating after being subjected to force. This avoids the problem that the existing tooling is unable to limit the flipped car frame. During the welding process, the car frame may be subjected to force and rotate, which may cause a risk of damage to the welded parts. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following is combined with Figure 1-3 This application is described in further detail.

[0030] See also Figure 1-3 The front frame welding turning tool comprises a bottom plate 1 with brackets 2 fixedly connected to the upper surfaces of both ends, a support beam 4 is slidably connected between the two brackets 2, and a clamping assembly is provided on the support beam 4. When the automobile frame needs to be welded, the automobile frame can be fixed on the support beam 4 through the clamping assembly.

[0031] Both brackets 2 are provided with sliding holes 3, and both ends of the support beam 4 are fixedly connected with connecting shafts 5 extending into the inner cavity of the sliding hole 3, so that the support beam 4 can slide up and down in the inner cavity of the sliding hole 3 through the connecting shafts 5 to adjust the height of the support beam 4.

[0032] A connecting ring 6 is sleeved on the connecting shaft 5, and an electric telescopic rod 7 whose output end is fixedly connected to the lower surface of the connecting ring 6 is fixedly connected in the inner cavity of the sliding hole 3. The height of the support beam 4 is adjusted by extending and retracting the electric telescopic rod 7.

[0033] A group of limit plates 8 are provided on the adjacent sides of the two brackets 2. The adjacent sides of the two limit plates 8 in each group are in sliding contact with the two sides of the support beam 4 respectively, and when the electric telescopic rod 7 is in a retracted state, the upper surface height of the support beam 4 is flush with the top height of the limit plates 8. Since the support beam 4 is a rectangular columnar structure, the limit plates 8 arranged on both sides of the support beam 4 can clamp and fix the support beam 4 from both sides to prevent the support beam 4 from rotating by itself after being subjected to force.

[0034] A turning assembly that cooperates with each other is installed on the connecting shaft 5 at one end of the support beam 4 and the bracket 2 near the connecting shaft 5. The user can drive the support beam 4 to rotate through the turning assembly, thereby realizing the turning of the automobile frame, which is convenient for welding the automobile frame.

[0035] Reference Figure 1 The bottom plate 1 is a rectangular plate structure, and fixing holes for fixing the bottom plate 1 are provided at the four corners of the bottom plate 1. The bottom plate 1 is provided to lower the center of gravity of the overall device and improve the stability of the overall device. The fixing holes are provided to facilitate users to fix the bottom plate 1 on the ground or an external rack through the fixing holes.

[0036] Reference Figure 1 and Figure 2 The clamping assembly includes two slip rings 12 sleeved on the support beam 4, and the outer walls of both sides of the two slip rings 12 are fixedly connected with symmetrically arranged clamping arms 14, and the top wall of the slip ring 12 is penetrated with a limit bolt 13 screwed with the slip ring 12, and one end of the limit bolt 13 located in the inner cavity of the slip ring 12 abuts against the support beam 4. When using, the user can place the car frame on the support beam 4 between the two slip rings 12, and then slide the two slip rings 12 toward each other, clamp the car frame through the clamping arms 14 arranged on both sides of the slip ring 12, and then screw the limit bolt 13 to fix the slip ring 12, so as to achieve the clamping work of the car frame.

[0037] Reference Figure 2 A screw rod 15 screwed to the clamping arm 14 is provided on one end of the clamping arm 14 away from the slip ring 12, and a rubber pad 16 is installed on one end of the screw rod 15 close to the middle section of the support beam 4. After the user clamps the car frame through the clamping arm 14, the screw rod 15 can be screwed to drive the rubber pad 16 to move toward the car frame, and the clamping force can be fine-tuned to improve the stability of the clamping of the car frame.

[0038] Reference Figure 2 The connecting end of the screw rod 15 and the rubber pad 16 is sleeved with a bearing 17, the inner ring of the bearing 17 is fixedly connected to the screw rod 15, and the outer ring of the bearing 17 is embedded in the rubber pad 16 and fixedly connected to the rubber pad 16. The bearing 17 is provided to rotatably connect the screw rod 15 and the rubber pad 16, so as to avoid the user rotating the screw rod 15 to drive the rubber pad 16 that is in contact with the car frame to rotate synchronously, resulting in friction between the rotation of the rubber pad 16 and the car frame, which may cause wear of the car frame.

[0039] Reference Figure 2 The flip assembly includes a driven gear 9 fixedly connected to one end of a connecting shaft 5 away from the support beam 4, and the flip assembly also includes a servo motor 10 fixedly connected to the bracket 2 above the driven gear 9, and a driving gear 11 fixedly connected to the output end of the servo motor 10. When the driven gear 9 and the driving gear 11 are meshed with each other, the user can start the servo motor 10 to drive the driving gear 11 to rotate, thereby driving the support beam 4 to rotate through the driven gear 9 and the connecting shaft 5, so as to realize the flipping of the automobile frame clamped and fixed on the support beam 4.

[0040] Reference Figure 3The servo motor 10 is fixedly connected with a mounting plate, and bolts are passed through the mounting plate, and the bolts are screwed to the bracket 2 after passing through the mounting plate. The mounting plate is provided to improve the stability of the installation of the servo motor 10, and the screw connection method is adopted, which is not only stable, but also convenient for users to install and disassemble the servo motor 10.

[0041] Reference Figure 2 When the electric telescopic rod 7 is in an extended state, the driven gear 9 moves up to mesh with the driving gear 11. The user can adjust the height of the support beam 4 through the electric telescopic rod 7 to achieve flipping or fixing the support beam 4.

[0042] The implementation principle of the present application is as follows: when in use, the user first clamps the automobile frame on the support beam 4 through the clamping arm 14, and then welds the automobile frame. When the automobile frame needs to be turned over during the welding process, the electric telescopic rod 7 can be started to extend, and the connecting shaft 5 in the inner cavity of the connecting ring 6 can be pushed to move up along the sliding hole 3 until the driven gear 9 installed on the connecting shaft 5 is meshed with the driving gear 11 installed at the output end of the servo motor 10. At this time, the support beam 4 slides out from the top of the limit plate 8, and the user can start the servo motor 10, and drive the support beam 4 between the two through the driving gear 11, the driven gear 9 and the connecting shaft 5. The brackets 2 rotate between each other, thereby driving the car frame clamped and fixed on the support beam 4 to flip over. When the car frame is adjusted and flipped to a suitable angle, the user starts the electric telescopic rod 7 to contract, and pulls the support beam 4 down to between the two limit plates 8 in each group through the connecting ring 6. The support beam 4 is clamped and fixed from both sides by the limit plates 8 to prevent the car frame on the support beam 4 from driving the support beam 4 to rotate after being stressed. This avoids the problem that the existing tooling cannot limit the flipped car frame. The user's car frame may be forced to rotate during welding, and there is a risk of damage to the welded parts.
