Description

Technical Field

[0001] This utility model relates to the field of motorcycle frame technology, specifically to a frame welding fixture. Background Technology

[0002] Currently, motorcycle frame welding involves assembling the various components together and fixing them on a horizontal surface for welding. However, current welding fixtures typically require manual adjustment of the fixed dimensions and lack automatic positioning and clamping structures, which reduces the welding speed of the motorcycle frame and is quite laborious. To address this, frame welding fixtures with positioning capabilities have emerged, such as the motorcycle frame welding fixture shown in CN222095169U. However, although this fixture can position and clamp the components, it can only weld on one side at a time. When welding the other side is required, the operator needs to move to the other side of the support to weld, which is very inconvenient. Utility Model Content

[0003] To address the shortcomings of existing technologies and solve the technical problem mentioned in the background that welding can only be performed on one side, and when welding the other side is required, the operator needs to move to the other side of the support to perform the welding, which is very inconvenient.

[0004] To solve this technical problem, the technical solution adopted by this utility model is as follows:

[0005] A vehicle frame welding fixture includes: a worktable, a moving mechanism, two clamping arms, and a rotating component. The moving mechanism is disposed on the worktable, and the two clamping arms are symmetrically disposed on the moving mechanism. The rotating component includes:

[0006] Base;

[0007] A connecting shaft is rotatably mounted on the base, and the connecting shaft is connected to the worktable so that the worktable can rotate relative to the base;

[0008] A handle, mounted on the base, has an exposed end outside the base for providing rotational force, and a drive end extending into the base and connected to the connecting shaft for transmission; a drive gear is mounted on the drive end of the handle, and a transmission gear is mounted on the connecting shaft, the drive gear and the transmission gear meshing; and

[0009] A fastener, mounted on the base, is used to lock or unlock the handle by engaging with it.

[0010] The handle includes a turntable and a drive wheel. One end of the drive wheel is fixedly mounted on the turntable, and the other end of the drive wheel is rotatably mounted on the base.

[0011] The fixing component includes a locking arm, a connecting frame, a support rod, and an elastic connector. The connecting frame is rotatably mounted on one side of the base via the support rod. One end of the elastic connector is fixedly mounted on one end of the base, and the other end is fixedly mounted on the connecting frame.

[0012] The locking arm includes an arc block and a fixing block, with the fixing block fixedly mounted on the arc block.

[0013] The connecting frame includes a Y-shaped block and a pressing block, with the pressing block fixedly disposed at one end of the Y-shaped block.

[0014] The advancements of this application compared to existing technologies are as follows:

[0015] By pressing the fixing member to release the handle, and then rotating the handle, the handle drives the transmission gear to rotate through the drive gear, and the transmission gear drives the worktable to rotate through the connecting shaft, thereby rotating the parts to facilitate welding.

Detailed Implementation

[0022] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0023] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0024] Please see Figures 1-4 This utility model provides a vehicle frame welding fixture, including a worktable 101, a moving mechanism 102, two clamping arms 103, and a rotating component. The moving mechanism 102 is disposed on the worktable 101, and the two clamping arms 103 are symmetrically disposed on the moving mechanism 102.

[0025] The base 104 of the rotating component provides support for the entire rotating structure. A connecting shaft 107 is rotatably mounted on the base 104 and connected to the worktable 101, allowing the worktable 101 to rotate relative to the base 104. The handle consists of a turntable 108 and a transmission wheel 109. One end of the transmission wheel 109 is fixed to the turntable 108, and the other end is rotatably mounted on the base 104. The exposed end of the turntable 108 facilitates the operator's application of force to rotate the handle. A drive gear 105 is mounted on the drive end of the handle, and a transmission gear 106 meshes with it on the connecting shaft 107. When the handle is rotated, the drive gear 105 drives the transmission gear 106 to rotate, which in turn drives the connecting shaft 107 and the worktable 101 to rotate.

[0026] Secondly, the fixing component is installed on the base 104, and it includes a locking arm (composed of an arc block 112 and a fixing block 113, with the fixing block 113 fixed to the arc block 112), a connecting frame (composed of a Y-shaped block 114 and a pressing block 115, with the pressing block 115 fixed to one end of the Y-shaped block 114), a support rod 110, and an elastic connector 111. The connecting frame is rotatably mounted on one side of the base 104 via the support rod 110, and one end of the elastic connector 111 is fixed to one end of the base 104, while the other end is fixed to the connecting frame.

[0027] Meanwhile, in actual operation, when it is necessary to rotate the worktable 101, press the button 115. The button 115 drives the Y-shaped block 114 to rotate. The Y-shaped block 114 rotates through the support rod 110, stretching the elastic connector 111 and causing the arc block 112 of the locking arm to move away from the transmission wheel 109, thereby releasing the handle. At this time, rotate the turntable 108. The turntable 108 drives the transmission wheel 109 to rotate. The transmission wheel 109 drives the drive gear 105 to rotate. The drive gear 105 drives the transmission gear 106 to rotate. The transmission gear 106 drives the worktable 101 to rotate to a suitable welding angle through the connecting shaft 107.

[0028] In addition, after the rotation is completed, the button 115 is released, the elastic connector 111 restores its elastic deformation, pushes the Y-shaped block 114 to rotate in the opposite direction, so that the arc block 112 re-contacts and locks with the transmission wheel 109, thereby fixing the handle and preventing the workbench 101 from rotating during the welding process.

[0029] Using the frame welding fixture of this embodiment, in practical use, the motorcycle frame component is first placed between the two clamping arms 103, and its position is adjusted and clamped by the moving mechanism 102. Then, the handle is released by pressing the button 115, and the angle of the worktable 101 is adjusted by rotating the turntable 108 so that the surface to be welded is in a suitable position. After releasing the handle to fix the button 115, welding can be performed. After welding one side, the button 115 is pressed again, and the angle of the worktable 101 is adjusted by rotating the turntable 108 to weld the other side, thereby improving the efficiency and convenience of the welding work.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
