Description

Technical Field

[0001] This utility model belongs to the technical field of motorcycle parts processing equipment, specifically relating to a directional handlebar welding fixture. Background Technology

[0002] In the motorcycle manufacturing industry, the handlebar stem mainly consists of the handlebar stem and the handlebar stem mount. The handlebar stem has straight sections at both ends and a curved section in the middle. The middle of this curved section is welded to the top of the handlebar stem mount, which 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 document with application number CN202510212636.0 discloses a welding fixture for bicycle handlebar tube sleeves, including a support station, a positioning mechanism on the support station, a rotating table, multiple positioning seats on the rotating table, the multiple positioning seats forming a positioning area, the positioning area for supporting the handlebar tube, and a clamping jaw on the rotating table, the clamping jaw clamping the sleeve so that the end of the sleeve contacts the middle of the handlebar tube in the positioning area.

[0004] In actual production and processing, tubular components need to be pre-connected to specific parts of the steering handlebar by welding to facilitate the installation of subsequent parts such as rearview mirrors, steering columns, and mounting brackets. However, existing fixtures only consider how to fix and clamp the main steering handlebar component to meet the subsequent welding operations of the robot, without considering how to place and position the parts to be welded. They rely more on the experience of the welding personnel, which leads to positional misalignment between the parts to be welded and the main component, affecting the overall quality consistency of the steering handlebar.

[0006] A directional pipe welding fixture, comprising:

[0007] The frame has a base plate, a top plate, and side plates symmetrically arranged between the base plate and the top plate;

[0008] The upper clamp is connected to the upper end of the top plate and acts on the outer wall of the middle section of the main component;

[0009] A side clamp is symmetrically connected to the outside of the side plate at a certain angle. The side clamp is used to clamp the end of the main component.

[0010] The main support is symmetrically arranged on both sides of the upper clamp and connected to the upper end of the top plate. The main support has a notch that conforms to the shape of the main component and supports the main component upward.

[0011] The main support has a limiting gap for placing welded parts;

[0027] like Figure 1 - Figure 3 As shown, a directional pipe welding clamp of the present invention includes a frame, an upper clamp 3, a side clamp 4, a main support 5, and a telescopic component 6.

[0028] The frame includes a base plate 10, a top plate 11, and side plates 12 symmetrically arranged between the base plate 10 and the top plate 11.

[0029] The upper clamp 3 is connected to the upper end of the top plate 11 and acts on the outer wall of the middle section of the main pipe 8;

[0030] The side clamps 4 are symmetrically connected to the outside of the side plate 12 at a certain angle. The side clamps 4 are used to clamp the end of the main pipe 8.

[0031] The main support 5 is symmetrically arranged on both sides of the upper clamp 3 and connected to the upper end of the top plate 11. The main support 5 has a notch 50 that conforms to the main pipe component 8 and supports the main pipe component 8 upward.

[0032] The main support 5 has a limiting gap 51 on which the welded part 9 can be placed;

[0033] The use of upper clamp 3, side clamp 4, and main support 5 can effectively clamp and fix the unique shape structure of the main pipe component 8, which is beneficial to the subsequent welding operation of the robot. Among them, since the main support 5 is provided with a limiting gap 51 for placing the welding part 9 and a positioning pin 61, the operator can easily and quickly place the part to be welded 9 in the predetermined position on the side of the main pipe component 8 during the welding operation. The positioning pin 61 can be inserted into the bottom of the welding part 9 to prevent the welding part 9 from shifting position from the main pipe component 8 during pre-placement and welding, thus meeting the welding process requirements of the entire directional pipe.

[0034] The telescopic component 6 is connected to the base plate 10, and the free end of the telescopic component 6 is provided with a positioning pin 61 that can extend into the limiting gap 51.

[0035] Since the positioning pin 61 is connected to the telescopic component 6, in addition to its inherent function, the length of the positioning pin 61 protruding from the top plate 11 can be adjusted according to the actual structural condition of the part to be welded 9, so that the length of the positioning pin 61 in the part to be welded 9 (tubular part) is not easy to shake relative to the main support 5 at the limiting gap 51, thus ensuring the welding quality.

[0036] Specifically, there are two sets of positioning pins 61. The free end of the telescopic component 6 is connected to the crossbeam 60, and the two sets of positioning pins 61 are symmetrically connected to the upper two sides of the crossbeam 60.

[0037] A through hole (not shown in the figure) is provided on the top plate 11 for matching the positioning pin 61.

[0038] In this embodiment, the telescopic component 6 can be a bolt mechanism, a telescopic cylinder, or other structures.

[0039] At least one of the upper clamp 3 and the side clamp 4 includes a handle 40 and a linkage mechanism 41. The connection method of the handle 40 and the linkage mechanism 41 can use existing technology and is easy to implement. It is not within the protection scope of this application. Therefore, it has at least the beneficial effects brought by the technical solution of the above embodiment, and will not be described in detail here.

[0040] In addition, such as Figure 2 As shown, the side clamp 4 in this embodiment has a pair of limiting pins 7 arranged on the outside of the main pipe member 8. This arrangement restricts the lateral degree of freedom of the main pipe member 8 when it is clamped by the side clamp 4.

[0041] 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.
