Description

Technical Field

[0001] This utility model relates to the field of metal welding equipment technology, and more specifically, to a motorcycle frame welding device. Background Technology

[0002] Motorcycle frame welding equipment is a specialized automated or semi-automated production equipment used to precisely connect metal tubes or plates into the main load-bearing structure of a motorcycle through welding processes. Its core function is to achieve high-precision positioning, firm clamping and stable welding of various components of the frame, ensuring the strength, dimensional accuracy and consistency of the welded joints. It is an indispensable key equipment in modern motorcycle manufacturing, which directly affects the performance, durability and driving experience of the whole vehicle.

[0003] For example, Chinese Patent Publication: Motorcycle Frame Welding Device, Application No.: CN201820159550.1, includes a frame, a tilting mechanism rotatably connected to the frame, a rotating rod rotatably connected to the frame, a support rod threadedly connected to the rotating rod, two clamping plates slidably connected to the support rod, a piston cylinder fixedly mounted on the frame, a piston slidably connected inside the piston cylinder, a piston rod fixedly connected to the piston, a horizontal plate fixedly connected to the end of the piston rod away from the piston, an air inlet pipe connected to the outside of the piston cylinder, and a valve connected to the piston cylinder's inner cavity. This solution allows for adjusting the workpiece to a horizontal position, facilitating processing, and is widely used in the welding process of workpieces.

[0004] However, in the above technical solution, the pneumatic leveling mechanism is used to achieve the flipping and horizontal positioning of the workpiece, which improves the work efficiency. However, the maintenance of its horizontal state depends on the pressure of the pneumatic system, which poses a safety hazard of accidental flipping of the workpiece due to air leakage or other accidents, affecting the welding stability and operational safety. Utility Model Content

[0005] The main purpose of this utility model is to provide a motorcycle frame welding device that can effectively solve the problem in the prior art where the workpiece is flipped and positioned horizontally by a pneumatic leveling mechanism, which improves work efficiency. However, the maintenance of its horizontal state depends on the pressure of the pneumatic system, which poses a safety hazard due to accidental air leakage, affecting welding stability and operational safety.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a motorcycle frame welding device, including a frame and a flipping mechanism rotatably connected to the frame. The flipping mechanism includes a rotating rod and a clamping assembly for clamping workpieces. The frame is also provided with a horizontal adjustment mechanism for driving the flipping mechanism to rotate to a horizontal position. A first rotating column is fixedly provided on the rotating rod. A first groove is provided on the first rotating column. A spring and an insertion post that can extend under the action of the spring force are provided in the first groove. The frame is provided with a second groove corresponding to the insertion post, which allows the insertion post to be inserted when the flipping mechanism is in a horizontal position. An unlocking assembly for driving the insertion post to retract into the first groove is provided at the second groove.

[0007] Preferably, the spring is fixedly installed in the first groove.

[0008] Preferably, the unlocking component includes a component base, on which a threaded post is threadedly provided, a worm gear is provided at one end of the threaded post, a worm is engaged with one side of the worm gear, a second rotating post is fixedly provided at one end of the worm, and a knob is fixedly provided at the end of the second rotating post away from the worm.

[0009] Preferably, the component base is provided with limit grooves on both sides, and a limit slider is slidably disposed in the limit groove.

[0010] Preferably, the component base slides in the second groove, the threaded column is rotatably mounted in the second groove, and the worm gear is rotatably connected to the frame.

[0011] Preferably, the side of the component base closest to the first rotating column is an arc-shaped surface, and the limiting slider is fixedly installed in the second groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects: (1) This utility model provides a mechanical locking mechanism consisting of a pin and a groove on the flipping mechanism. When the workpiece is adjusted to a horizontal position, the pin automatically pops out under the action of the spring to achieve reliable locking, effectively preventing the workpiece from flipping due to accidents such as gas circuit failure during the welding process, and ensuring the safety of personnel and workpiece.

[0015] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0016] like Figures 1 to 3 As shown, a motorcycle frame welding device includes a frame 1 and a flipping mechanism rotatably connected to the frame 1. The flipping mechanism includes a rotating rod 2 and a clamping assembly for clamping workpieces. The frame 1 is also provided with a horizontal adjustment mechanism for driving the flipping mechanism to rotate to a horizontal position. A first rotating column 3 is fixedly provided on the rotating rod 2. A first groove 4 is provided on the first rotating column 3. A spring 5 and an insertion post 6 that can extend under the action of spring force are provided in the first groove 4. The frame 1 is provided with a second groove 7 corresponding to the insertion post 6, which allows the insertion post 6 to be inserted when the flipping mechanism is in a horizontal position. An unlocking assembly 8 is provided at the second groove 7 for driving the insertion post 6 to retract into the first groove 4.

[0017] like Figure 4 As shown, in another embodiment of the present invention, the unlocking component 8 includes a component base 801, a threaded post 802 is threaded on the component base 801, a worm gear 803 is provided on one side of the threaded post 802, a worm 804 is meshed on one side of the worm gear 803, a second rotating post 805 is fixedly provided on one side of the worm 804, and a knob 806 is fixedly provided on the side of the second rotating post 805 away from the worm 804. Both sides of the component base 801 are provided with limiting grooves 807, and a limiting slider 808 is slidably disposed in the limiting grooves 807. When it is necessary to release the lock to flip the workpiece, the knob 806 drives the worm 804 to rotate through the second rotating column 805. The worm 804 drives the worm wheel 803, which meshes with it, to rotate, thereby causing the threaded column 802 connected to the worm wheel 803 to rotate. Since the component base 801 slides with the limiting slide groove 807 fixed in the second groove 7 through the limiting sliders 808 on both sides, it cannot rotate on its own. Therefore, under the action of thread transmission, the rotational motion of the threaded column 802 is converted into the linear motion of the component base 801 along the axis of the threaded column 802. The component base 801 moves smoothly towards the first rotating column 3, and its front arc surface abuts against and presses the insertion post 6, overcoming the elastic force of the spring 5, forcing the insertion post 6 to completely retract into the first groove 4, thereby disengaging it from the second groove 7, releasing the lock, and allowing the flipping mechanism to rotate freely.

[0018] The working principle of this motorcycle frame welding device: In use, when the horizontal adjustment mechanism drives the flipping mechanism and the workpiece on it to rotate to the horizontal welding position, the first rotating column 3, which is fixed on the rotating rod 2, rotates to a specific angle, so that the first groove 4 on the first rotating column 3 is aligned with the second groove 7 on the frame 1. The preload of the spring 5 then pushes the insert 6 to automatically pop out of the first groove 4 and insert into the second groove 7 to form a mechanical interlock, thereby reliably locking the flipping mechanism in the horizontal position and preventing accidental rotation during welding. When unlocking is required, the operator rotates the knob 806, which drives the worm gear 804 to rotate through the second rotating column 805, driving the worm wheel 803 and the threaded column 802 that mesh with it to rotate. Under the sliding cooperation of the limit slider 808 and the limit groove 807, the rotational motion of the threaded column 802 is converted into the linear motion of the component base 801, so that its arc surface presses the insert 6 back into the first groove 4 to achieve unlocking, preventing the workpiece from suddenly flipping due to accidents such as gas circuit failure during welding, and ensuring the safety of personnel and workpieces.

[0019] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
