Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric vehicle frame technology, and in particular to a fixing device for welding electric vehicle frames. Background Technology
[0002] Electric vehicles use batteries as their energy source and convert electrical energy into mechanical energy through components such as controllers and motors to move. The speed is changed by controlling the magnitude of the current. The electric vehicle frame is used to provide support and is generally formed by welding. It is a three-dimensional structure made of welded metal tubes. During welding, the frame needs to be fixed by fixing devices.
[0003] A search revealed a fixing device for welding electric vehicle frames, disclosed in publication number "CN219521024U". The device includes a base and a guide rod mounted on the base, with its top end fixedly connected to a top plate. A screw is rotatably mounted between the base and the top plate, and the screw is threadedly connected to a movable frame slidably connected to the guide rod. A rotating frame is rotatably mounted on the movable frame, and a first cylinder is hinged between the rotating frame and the movable frame. A second motor is mounted on the rotating frame, and the output shaft of the second motor is fixedly connected to the rotating frame. Second cylinders are mounted on both sides of the rotating frame, and clamping mechanisms are mounted on the telescopic ends of the second cylinders. This invention clamps and fixes the frame using the clamping mechanism. The rotating frame allows adjustment of the frame's orientation, and the first cylinder allows adjustment of the rotating frame's angle, enabling the frame to be placed at an angle. Furthermore, after fixing the frame, the welding position can be adjusted freely without needing to be re-fixed.
[0004] While this solution allows for arbitrary angle adjustment of the frame, it does not enable smooth handling of the frame during use. The welded joints of a freshly welded frame are relatively fragile, and collisions during handling can easily cause cracks in the welds, affecting the frame's usability. Therefore, improvements are needed. Utility Model Content

[0054] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a fixing device for welding electric vehicle frames.
[0055] A fixing device for welding electric vehicle frames includes a support frame 1 and a support groove 2, the support groove 2 being formed on the support frame 1; it also includes: a support block 3, disposed in the support groove 2 and slidably connected to the support groove 2; a telescopic mechanism, disposed on the support block 3, for moving the frame; and a moving mechanism, disposed on the telescopic mechanism, for moving the frame.
[0056] In a preferred embodiment, the telescopic mechanism includes: a telescopic frame 4, disposed on a support block 3 and fixedly connected to the support block 3; a telescopic cylinder 5, fixedly connected to the telescopic frame 4; a telescopic groove 6, formed on the telescopic frame 4; a telescopic block 7, disposed within the telescopic groove 6, slidably connected to the telescopic groove 6, and fixedly connected to the output end of the telescopic cylinder 5; a telescopic column 8, fixedly connected to the telescopic block 7; and a rotating component disposed on the telescopic block 7.
[0057] This configuration allows the telescopic cylinder 5 to slide within the telescopic groove 6 when it is in operation, causing the telescopic block 7, which is fixedly connected to the output end of the telescopic cylinder 5, to move away from the telescopic frame 4, thereby driving the rotating components to operate.
[0058] In a preferred embodiment, the rotating component includes: two first rotating shafts 9, which are symmetrically arranged on the telescopic block 7 and fixedly connected to the telescopic block 7; a first rotating plate 10, which is rotatably connected to the first rotating shafts 9; a second rotating shaft 11, which is arranged on the first rotating plate 10 and rotatably connected to the first rotating plate 10; a second rotating plate 12, which is rotatably connected to the second rotating shaft 11; and a third rotating shaft 13, which is arranged on the second rotating plate 12, rotatably connected to the second rotating plate 12, and fixedly connected to the telescopic frame 4.
[0059] This configuration allows the first rotating plate 10, which is rotatably connected to the first rotating shaft 9, to rotate, and the second rotating plate 12, which is rotatably connected to the second rotating shaft 11, to rotate around the axis of the third rotating shaft 13. This causes the moving block 14, which is fixedly connected to the telescopic column 8, to move downwards towards the support frame 1 until the frame comes into contact with the ground, thereby enabling the safe unloading of the frame.
[0060] In a preferred embodiment, the moving mechanism includes: a moving block 14, which is disposed on the telescopic column 8 and fixedly connected to the telescopic column 8; a moving frame 15, which is disposed on the moving block 14 and fixedly connected to the moving block 14; a moving motor 16, which is fixedly connected to the moving frame 15; a moving shaft 17, which is fixedly connected to the output end of the moving motor 16; and a sliding component, which is disposed on the moving block 14.
[0061] This configuration allows the moving motor 16 to rotate when it is running, driving the moving shaft 17, which is detachably and fixedly connected to the output end of the moving motor 16, to rotate and drive the sliding components.
[0062] In a preferred embodiment, the sliding component includes: a sliding groove 18 formed on the movable block 14; a sliding block 19 disposed in the sliding groove 18, slidably connected to the sliding groove 18, and threadedly connected to the movable shaft 17; and a clamping component disposed on the sliding block 19.
[0063] This configuration causes the sliding block 19, which is threadedly connected to the moving shaft 17, to rotate, thereby causing the sliding block 19 to slide within the sliding groove 18, which in turn causes the clamping frame 20, which is fixedly connected to the sliding block 19, to move.
[0064] In a preferred embodiment, the clamping component includes: a clamping frame 20, disposed on and fixedly connected to the sliding block 19; a clamping shaft 21, disposed on the clamping frame 20 and rotatably connected to the clamping frame 20; a clamping block 22, fixedly connected to the clamping shaft 21; and two clamping plates 23, symmetrically disposed on the clamping shaft 21 and threadedly connected to the clamping shaft 21. An elastic pad 24 is provided on the clamping plate 23.
[0065] This configuration allows the rotating clamping block 22 to rotate the clamping shaft 21, which is fixedly connected to the clamping block 22, on the clamping frame 20. This, in turn, causes the clamping plate 23, which is threadedly connected to the clamping shaft 21, to rotate. This causes the clamping plates 23 to move closer together until the elastic pad 24 on the clamping plate 23 contacts the frame, thus fixing the frame.
[0066] Working principle: In use, first place the frame on the clamping plate 23, then rotate the clamping block 22, so that the clamping shaft 21 fixedly connected to the clamping block 22 rotates on the clamping frame 20, thereby driving the clamping plate 23 threadedly connected to the clamping shaft 21 to rotate, so that the clamping plates 23 move closer to each other until the elastic pad 24 on the clamping plate 23 contacts the frame, thereby fixing the frame. When welding is required on the frame near the support frame 1, start the moving motor 16, drive the moving shaft 17 detachably fixedly connected to the output end of the moving motor 16 to rotate, so that the sliding block 19 threadedly connected to the moving shaft 17 rotates, driving the sliding block 19 to slide in the sliding groove 18, thereby moving the clamping frame 20 fixedly connected to the sliding block 19, thereby moving the frame away from the support frame 1, making it easier to weld the frame.
[0067] Then, after the frame welding is completed, the telescopic cylinder 5 is activated, which drives the telescopic block 7, which is fixedly connected to the output end of the telescopic cylinder 5, to slide in the telescopic groove 6. This causes the telescopic column 8, which is fixedly connected to the telescopic block 7, to move away from the telescopic frame 4. This causes the first rotating plate 10, which is rotatably connected to the first rotating shaft 9, to rotate. This causes the second rotating plate 12, which is rotatably connected to the second rotating shaft 11, to rotate around the axis of the third rotating shaft 13. This causes the moving block 14, which is fixedly connected to the telescopic column 8, to move downwards from the support frame 1 until the frame contacts the ground, thereby achieving safe unloading of the frame.
[0068] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
