Description
Technical Field
[0001] The utility model relates to a motorcycle frame tooling, in particular to an inverted combined tooling for a motorcycle main frame. Background Art
[0002] The motorcycle frame is one of the core components of a motorcycle. It is welded by many metal pipes into a three-dimensional space structure, and many functional lugs and metal plates are welded according to actual installation needs. Therefore, many welding jigs are designed for welding.
[0003] The motorcycle main frame is one of the important components of the motorcycle frame. As Figure 1 , 2 shown, the front frame of the motorcycle is composed of a flank pipe 3, a bracket 1, and a front support frame 2 that are welded end to end in sequence to form a closed loop. The front support frame 2 is composed of a riser 2-2 and a front support pipe 2-1. An upper shock absorber support frame and an engine rear suspension 5 are also arranged between the two flank pipes 3. Since the flank pipe 3 is long and large in volume, it is not easy to fix when placed vertically. The existing welding process is to first fix the bracket 1 and the front support frame 2 on a welding tooling for welding, then remove the two and fix them on another welding tooling with the two flank pipes 3 for welding and fixing, and finally weld a reinforcing member 6 fixedly connected to both the front support pipe 2-1, the riser 2-2, and the flank pipe 3, as well as the upper shock absorber support frame 4 and the engine rear suspension 5.
[0004] It can be seen that the existing welding method not only has low processing efficiency, but multiple positioning will increase the processing error. Since both the bracket 1 and the front support pipe 2-1 are special-shaped parts with non-flat structures, the limiting and fixing process on the welding tooling is cumbersome. And the threaded hole 3-2 of the flank pipe 3 needs to be coaxially arranged with the cross pipe of the bracket 1, so the relative position requirements of the bracket 1 and the front support pipe 2-1 are relatively high, and multiple positioning will also affect the coaxiality. Content of the Utility Model
[0005] The utility model aims to provide an inverted combined tooling for a motorcycle main frame, which can perform the welding and fixing of the motorcycle main frame through one-time positioning and installation, with high processing efficiency and small positioning error.
[0006] The inverted combined tooling for the motorcycle main frame in this scheme includes a first limit seat and a first hinge seat for supporting and fixing the flank pipe.

The first hinge seat is provided with a positioning hole and a positioning shaft adapted to the positioning hole, and the positioning hole corresponds to the connecting shaft hole on the flank pipe.
[0007] On the front side of the first limit seat, a second limit seat for positioning the reinforcing member and a first fixing portion for limiting and fixing the riser are successively provided; the first fixing portion includes a limit frustum and a pressing block that can move along the axial direction of the riser, facilitating the fixing or removal of the riser. The reinforcing member is placed on the second limit seat and abuts against the riser.
[0008] Between the first limit seat and the first hinge seat, a second fixing portion for fixing the upper shock-absorbing support frame, a third limit support for fixing the engine suspension, and a limit suspension are provided; the limit suspension includes two cantilevers arranged staggeredly front and back, and a limit hole is provided on each cantilever, and the limit hole is detachably connected with a limit pin. The limit hole corresponds to the connection hanging hole on the engine suspension, and by cooperating with the third limit support, the engine suspension can be fixed at the required rotation angle.
[0009] Behind the first hinge seat, a second hinge seat and a suspension frame for fixing the bracket are successively arranged. A positioning hole and a positioning shaft adapted to the positioning hole are provided on the second hinge seat, and the bracket connection hole is hinged to the positioning hole. The suspension frame is an L-shaped similar to the bending degree of the bracket, the suspension frame can be flipped around one end thereof, and the other end of the suspension frame can be lapped on the front support frame; a limit clamping seat and a clamping jaw are fixedly connected to the suspension frame for fixing the bracket on the suspension frame.
[0010] Furthermore, multiple groups of limit frames are also provided on both sides of the first limit seat, each group of limit frames is arranged in mirror symmetry, the limit frames move towards or away from each other, and the limit frames are used for fixing the water tank mounting parts; the limit frame is provided with a limit groove, and a positioning pin is provided at the bottom of the limit groove.
[0011] Furthermore, a clamping jaw is also provided on one side of the limit frame, and the clamping jaw is Z-shaped; one end of the clamping jaw is used for pressing the U-shaped part, the other end is hinged to the driving part, and the bent part of the clamping jaw close to the driving part is hinged to the limit frame.
[0012] Furthermore, a pressing block is also included and is arranged between the first limit seats, and the pressing block can reciprocate horizontally. The pressing block can press the reinforcing member against the side of the riser to ensure that it will not move during welding.
[0013] Furthermore, a limit platform and a pair of clamping jaws located on the limit platform are provided between the pressing block and the second fixing portion; specifically, the middle parts of the two clamping jaws are hinged to the limit platform through a connecting rod, and the tail ends of the two clamping jaws are hinged to the same driving rod. The limit platform is inclined.
[0014] Furthermore, since there are through holes that need to be coaxially arranged on the flank pipe and the front support pipe, the limit suspension, the first hinge seat, and the second hinge seat are all fixed on the same pillar, which is convenient for positioning.
[0015] Further, the second fixing part includes two fixing blocks and two fixing pins; fixing holes are provided on the fixing blocks, and the fixing pins are detachably connected to the fixing holes.
[0016] Further, the suspension bracket further includes a pressing plate, and the pressing plate has a "cross" structure and is used to press the reinforcing piece against the connection part between the bracket and the front support frame.
[0017] The advantages of the present utility model are as follows: The motorcycle main frame is inverted on the present utility model, that is, the two side wing tubes are below, and the bracket and the front support frame are above. The long section of the side wing tube is placed horizontally, and the side wing tube can be limited and fixed only through two places, namely the first limit seat and the first hinge seat; the bracket has a small and compact structure, and can be hovered and fixed above the side wing tube by grasping with the L-shaped cantilever without damaging the surface; the front support frame can be fixed through the vertical pipe, with fewer positioning parts and a simple structure.
