Technical Field

[0001] This utility model belongs to the field of motorcycle parts technology, specifically relating to a clamping tool for processing motorcycle handlebars. Background Technology

[0002] In the motorcycle manufacturing industry, the motorcycle handlebar stem mainly consists of the handlebar stem and the handlebar stem mount. The handlebar stem has straight sections at both ends, and its middle section is welded to the top of the handlebar stem mount. The handlebar stem mount is a round tube. The motorcycle's steering column is inserted into the lower end of the handlebar stem mount and secured with bolts. The rider transmits steering force to the handlebar stem mount and steering column by controlling the straight sections of the handlebar stem, and the steering column controls the forward direction of the motorcycle's front wheel.

[0003] Chinese patent application number CN200820097877.7 discloses a motorcycle handlebar, including a handlebar tube and a handlebar tube seat. The handlebar tube has straight sections at both ends and a curved section in the middle. The handlebar tube seat is a round tube. The feature is that a curved tube is installed between the handlebar tube seat and the curved section of the handlebar tube. The middle part of the curved tube is welded to the handlebar tube seat. Curved tube lugs are welded to both ends and the middle part of the curved tube. Handlebar tube lugs are welded to both ends and the middle part of the curved tube. Through holes are drilled in both the curved tube lugs and the handlebar tube lugs.

[0004] In the processing of the directional handle tube, multiple parts are welded or cut. For example, when the main body of the directional handle tube is connected to the tie rod, tooling is used to fix the main body of the tube during the welding or length cutting. However, after changing the tube model, the diameter of the tube will change, and the fixture needs to be changed accordingly. This process is inconvenient, and traditional tooling cannot meet its requirements. Utility Model Content

[0017] like Figure 1 - Figure 5 As shown, the present invention provides a motorcycle handlebar tube processing and clamping fixture, which includes a base 1, a support frame and an adjustment component 3. The base 1 is used to connect to the control panel; The support frame is connected to the upper end of the base 1; At least three sets of adjustment components 3 are distributed around the outer periphery of the center of the support frame, and each set of adjustment components 3 is slidably connected to the support frame; The support frame includes a lower bracket 20 connected to the base 1, and an upper bracket 21 hinged to one end of the lower bracket 20. The other end of the upper bracket 21 and the lower bracket 20 are connected by a fastener, which is a commonly used bolt.

[0018] The adjustment components 3, which can be slidably connected to the support frame, allow the relative positions of the working ends of several adjustment components 3 and the workpiece to be changed independently according to the workpiece diameter processing requirements. While ensuring that the workpiece can be clamped, the clamping and fixing points can be redefined. The multiple sets of adjustment components 3 are arranged in a ring shape, making the clamping and fixing force on the workpiece more uniform and adaptable to the welding / cutting requirements of pipe fittings 4 of different diameters.

[0019] The support frame uses an upper bracket 21 and a lower bracket 20 that are hinged to each other, which makes it more convenient to disassemble and place the workpiece.

[0020] In this embodiment, an adjustment component 3 is provided on the upper support 21, with its working end pointing vertically downward.

[0021] like Figure 4 , Figure 5 As shown, specifically, the adjustment component 3 includes a first slider 30 and a second slider 31 arranged on both sides of the support frame, and the first slider 30 and the second slider 31 are detachably connected.

[0022] The first slider 30 and the second slider 31 have a corresponding connecting structure on opposite sides.

[0023] Specifically, the connecting structure includes a slide groove 32 and a protrusion 33. This connecting structure facilitates the assembly and disassembly of the components in the adjustment assembly. The slide groove 32 can be a dovetail groove, allowing the first and second sliders to be pulled apart only from their ends.

[0024] After the first slider 30 and the second slider 31 of the adjustment component 3 are assembled, the screw with the handle is engaged with the first slider 30 or the second slider 31. By turning the handle, the screw moves relative to the other side. The elongation of the screw head in the adjustment component determines the sliding distance of the adjustment component relative to the support frame.

[0025] A racetrack-shaped through hole is provided on the side of the first slider 30 or the second slider 31, and is connected to the support frame by bolts.

[0026] Additionally, the contact end includes a rotary wheel 34 connected to the first slider 30 and / or the second slider 31.

[0027] Unless otherwise specified, fixed connections can be riveting, welding, bolting, etc., while movable connections can be hinged, etc.

[0028] This utility model also discloses the application of the above-mentioned tooling and conveying device when used together, such as Figure 6 As shown, when this clamping fixture is used in the conveying device, its position and the state of clamping the pipe are such that after the pipe 4 to be processed is transported to a certain length position by the conveying device 5, this fixture clamps it, making the pipe 4 stable and easy to cut or weld with other workpieces.

[0029] like Figure 3As shown, in the above application, the contact end can also have other structural forms, such as an arc-shaped rotating block 35. This arc-shaped rotating block 35 conforms to the shape of the pipe fitting 4 and is connected to the first slider 30 and / or the second slider. By rotating the handle and screw, the relative distance between the inner side of the arc-shaped rotating block 35 and the outer wall of the pipe fitting 4 can be adjusted to accommodate pipe fittings 4 of different diameters. With the arc-shaped rotating block 35, the contact area with the outer wall of the pipe fitting 4 is greatly increased compared to the rotating wheel 34, making the pipe fitting 4 clamped and fixed more securely.

[0030] The outer wall of the rotating wheel 34 or the arc-shaped rotating block 35 is provided with an elastic rubber sheet. It is worth noting that the elastic rubber sheet can be made of materials with cushioning properties, such as rubber, which can reduce damage to the surface of the pipe fitting 4.

[0031] The above are merely embodiments of this utility model. Commonly known structures and characteristics are not described in detail here. Those skilled in the art are aware of all common technical knowledge in the field prior to the application date or priority date, are aware of all existing technologies in that field, and have the ability to apply conventional experimental methods prior to that date. Those skilled in the art can, based on the guidance provided in this application, improve and implement this solution in combination with their own capabilities. Some typical known structures or methods should not be obstacles for those skilled in the art to implement this application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model. These should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
