Description

Technical Field

[0001] The utility model relates to a motorcycle frame tooling, in particular to a motorcycle head pipe assembly. 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 head pipe assembly is one of the important components of the motorcycle frame. As Figure 1 , 2 shown, a connecting bracket 1-2, a triangular connecting plate 1-7, a connecting ear 1-5 and a lug 1-8 are welded on the periphery of the head pipe 1-1 to form the motorcycle head pipe assembly. Since the connecting bracket 1-2 is located above the triangular connecting plate 1-7, and the included angle between the connecting bracket 1-2 and the symmetry axis of the triangular connecting plate 1-7 is fixed; the connecting ear is welded at a specified position on the side wall of the triangular connecting plate, so each welded connector needs to be positioned once. Since there is partial overlap between the projections of the connecting bracket and the triangular connecting plate in the vertical direction, as Figure 2 shown, that is, the motorcycle head pipe assembly is an asymmetric structure, resulting in a cumbersome positioning process. It can be seen that the existing welding method not only has low processing efficiency, but also multiple positioning will increase the processing error. The connecting bracket, the triangular connecting plate and the connecting ear are all special-shaped parts with non-flat structures, and the relative positions of adjacent two parts have high requirements, resulting in a cumbersome limiting and fixing process. Summary of the Utility Model

[0004] The utility model aims to provide a combined tooling for a motorcycle head pipe assembly, which can realize self-adaptive limiting, reduce the limiting process before welding, and improve the processing efficiency.

[0005] The combined tooling for the motorcycle riser assembly in this solution includes a first limiting mechanism and a second limiting mechanism. The first limiting mechanism includes a first limiting module that can move vertically and a first pressing member that can move horizontally. A boss for limiting the riser is provided at the lower end of the first limiting module. The riser is vertically placed below the first limiting module. While the first limiting module presses the riser, the boss extends into the upper port of the riser and fits with the upper port, realizing the axial and radial positioning of the riser. A limiting plate is provided on the side of the first limiting module. The upper end of the connecting bracket is buckled on the limiting plate and is pressed against the limiting plate by the first pressing member. The second limiting mechanism includes a second limiting member, which is triangular and adapted to the triangular connecting plate. The upper end surface of the second limiting member is an inclined surface and is inclined towards the riser. After buckling the triangular connecting plate on the second limiting member, due to the inclined upper end surface of the second limiting member, the triangular connecting plate slides along this inclined surface until it abuts against the riser. It also includes a guiding and limiting member located on one side of the second limiting member. The upper end surface of the guiding and limiting member is an inclined surface and is inclined towards the second limiting member. The connecting ear is buckled on the guiding and limiting member and slides along the upper end surface of the guiding and limiting member under the action of its own weight until it abuts against the triangular connecting plate.

[0006] Furthermore, the second limiting mechanism further includes a second pressing member. The second pressing member can reciprocate along the axis direction of the second limiting member. The triangular connecting plate is further fixed by the second pressing member to ensure the welding precision. A positioning post is provided on the second pressing member, and this positioning post is adapted to the through hole for positioning on the triangular connecting plate to prevent the triangular connecting plate from shifting due to the pressure of the second pressing member.

[0007] Furthermore, it also includes an actuating mechanism. The actuating mechanism includes a guiding slide block, a guiding column, and a push rod. The first limiting module, the first pressing member, and the second pressing member are respectively driven by the actuating mechanism.

[0008] Furthermore, the end of the guiding and limiting member away from the second limiting member is a curved surface that bends upward, and this curved surface is adapted to the free end of the connecting ear.

[0009] Furthermore, positioning holes and positioning pins are also provided on the guiding and limiting member for further fixing the connecting ear.

[0010] Furthermore, it also includes a third limiting mechanism. The third limiting mechanism is located below the first limiting module. The third limiting mechanism includes a limiting seat and a limiting block located on one side of the limiting seat. A positioning groove is provided on the limiting block, and the support ear is clamped in this positioning groove to prevent the riser from rotating during welding.

[0011] Further, a positioning head is provided on the first pressing member, and the positioning head is adapted to a through hole a for positioning on the connecting bracket; a guiding hole adapted to the positioning head is provided on the limiting plate. Preferably, the diameter of the guiding hole is slightly larger than the diameter of the positioning head, and the radial cross-sectional shape of the positioning head is the same as the shape of the through hole for positioning on the connecting bracket.

[0012] Further, a relief groove is also provided on the limiting plate, and the guiding hole is located in the relief groove. The relief groove can accommodate the upper end of the connecting bracket. Preferably, the relief groove is similar in shape to the upper end of the connecting bracket.

[0013] Further, a bottom plate is further included, and the first limiting mechanism and the second limiting mechanism are respectively arranged on the bottom plate through supports.

[0014] The advantages of the present utility model are as follows: The triangular connecting plate is buckled on the second limiting member and slides along the upper end surface of the second limiting member until it abuts against the riser pipe; then the connecting ear is buckled on the guiding limiting member and slides along the upper end surface of the guiding limiting member until it abuts against the triangular connecting plate. Both the triangular connecting plate and the connecting ear slide to the designated positions by their own weights, realizing self-adaptive limiting, reducing the limiting process before welding, and improving the processing efficiency. Only one clamping and positioning is required to complete the fixation of the motorcycle riser pipe assembly, further improving the processing accuracy. Description of the Drawings

[0031] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0032] According to Figures 3 to 10As shown in the figure, the combined tooling for the motorcycle head pipe assembly includes a first limiting mechanism and a second limiting mechanism. The first limiting mechanism includes a first limiting module 2-1 that can move vertically and a first pressing member 2-2 that can move horizontally. Both the first limiting module 2-1 and the first pressing member 2-2 are connected to an actuator. The above actuator includes a guiding slide block 4-1, a guiding column 4-2, and a push rod 4-3. The lower end of the first limiting module 2-1 is provided with a boss 2-11 for head pipe limiting. The head pipe is vertically placed below the first limiting module 2-1. While the first limiting module 2-1 presses the head pipe, the boss 2-11 extends into the upper port 1-9 of the head pipe and is adapted to the upper port of the head pipe, realizing the axial and radial positioning of the head pipe 1-1. A limiting plate 2-12 is provided on the side of the first limiting module 2-1; the upper end of the connecting bracket 1-2 is buckled on the limiting plate 2-12 and is pressed against the limiting plate 2-12 by the first pressing member 2-2. The second limiting mechanism includes a second limiting member 3-1, and the second limiting member 3-1 is triangular and adapted to the triangular connecting plate 1-7. The upper end surface of the second limiting member 3-1 is an inclined surface and is inclined towards the head pipe. After the triangular connecting plate 1-7 is buckled on the second limiting member 3-1, due to the inclined surface of the upper end surface of the second limiting member 3-1, the triangular connecting plate 1-7 slides along the inclined surface until it abuts against the head pipe.

[0033] As a further improvement of the present utility model, the second limiting mechanism further includes a second pressing member 3-2. The second pressing member 3-2 is connected to an actuator and can reciprocate along the axis direction of the second limiting member 3-1. Specifically, the second pressing member 3-2 is sequentially connected to a guiding column 4-2 and a push rod 4-3. The guiding column 4-2 is preferably square in cross-section. The triangular connecting plate 1-7 is further fixed by the second pressing member 3-2 to ensure the welding accuracy. A positioning column 3-3 is provided on the second pressing member 3-2, and the positioning column 3-3 is adapted to the through hole c1-6 on the triangular connecting plate 1-7 to prevent the triangular connecting plate 1-7 from being displaced due to the pressure of the second pressing member 3-2. Preferably, guiding ribs 3-11 are provided on both sides of the second limiting member 3-1, and a U-shaped notch is provided at one end of the second limiting member 3-1 close to the head pipe.

[0034] As a further improvement of the present utility model, one end of the guiding and limiting member 2-3 away from the second limiting member 3-1 is a curved surface 2-31 that bends upward, and this curved surface 2-31 is adapted to the free end of the connecting ear 1-5. Specifically, the guiding and limiting member 2-3 is adapted to the shape of the connecting ear 1-5. When the connecting ear 1-5 is buckled on the guiding and limiting member 2-3, the two can be closely attached. The guiding and limiting member 2-3 is also provided with a positioning hole and a positioning pin, and this positioning hole corresponds to the through hole b1-4 on the connecting ear 1-5 for further fixing of the connecting ear 1-5.

[0035] As a further improvement of the present utility model, it further includes a third limiting mechanism located below the first limiting module 2-1. The third limiting mechanism includes a limiting seat 5-1 and a limiting block 5-2 located on one side of the limiting seat 5-1. The limiting block 5-2 is provided with a positioning groove 5-3. The lower end of the riser pipe sits on the limiting seat 5-1, and the ear 1-8 at the lower end of the riser pipe is stuck in this positioning groove 5-3, which can prevent the riser pipe from rotating during welding.

[0036] As a further improvement of the present utility model, the first pressing member 2-2 is provided with a positioning head 2-21, and this positioning head 2-21 is adapted to the through hole a1-3 for positioning on the connecting bracket 1-2. The limiting plate 2-12 is provided with a guiding hole 2-14 adapted to the positioning head 2-21. Preferably, the diameter of the guiding hole 2-14 is slightly larger than the diameter of the positioning head 2-21, and the radial cross-sectional shape of this positioning head 2-21 is the same as the shape of the through hole for positioning on the connecting bracket 1-2. The limiting plate 2-12 is also provided with a relief groove 2-13, and the guiding hole 2-14 is located in this relief groove 2-13. This relief groove 2-13 can accommodate the upper end of the connecting bracket 1-2. Preferably, this relief groove 2-13 is similar in shape to the upper end of the connecting bracket 1-2.

[0037] As a further improvement of the present utility model, it further includes a bottom plate 7, and the first limiting mechanism and the second limiting mechanism are respectively arranged on the bottom plate 7 through a support 6.

[0038] During use, the lower end of the riser pipe 1-1 is seated on the limiting seat 5-1, and the ear 1-8 at the lower end of the riser pipe 1-1 is stuck in the positioning groove 5-3. The first limiting module 2-1 moves downward to press the riser pipe, and at this time, the boss 2-11 is located inside the upper port 1-9 of the riser pipe. After the axial and radial positioning of the riser pipe 1-1 is completed, the connecting bracket 1-2 is fixed by the first pressing member 2-2. Then, the triangular connecting plate 1-7 and the connecting ear 1-5 are successively buckled on the second limiting member 3-1 and the guiding and limiting member 2-3, and self-adaptive limiting and positioning are realized under the action of self-weight without manual adjustment by workers.
