[0031] To facilitate the understanding of the present invention, the present application will be described more comprehensively below with reference to the relevant drawings; the drawings show preferred embodiments of the present invention, but the present invention can be implemented in many different forms and is not limited to the embodiments described herein; on the contrary, the purpose of providing these embodiments is to enable a more thorough and comprehensive understanding of the disclosed content of the present invention.

[0032] It should be noted that the terms “vertical”, “horizontal”, “up”, “down”, “left”, “right” and similar expressions used in this document are only for illustrative purposes and do not represent the only implementation method.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which the present invention belongs; the terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0034] See also Figure 1 The invention relates to a fixing device for welding a bicycle front fork. The invention optimizes and improves a limiting assembly for welding a bicycle front fork in the prior art. The sleeve covers the bottom of the U-shaped tube. The main function is to adjust the gap between the U-shaped tube and the straight tube to reduce the tolerance and ensure accurate alignment during welding. The sleeve allows fine adjustment of the position of the U-shaped tube, and the fine adjustment can improve the welding accuracy. The bottom of the lifting platform is fixedly connected to the sleeve, which can drive the sleeve to move radially, so that after the U-shaped tube is initially fixed, its position can be further adjusted to reduce the tolerance. The mobility of the lifting platform provides convenience for accurate alignment before welding, and it can be withdrawn after initial fixation without affecting subsequent welding operations. The fixing seat provides support for the limiting hook to ensure that the limiting hook remains stable during the welding process and does not move. The limiting hook is an arc-shaped body, and the U Placing the top of the U-shaped tube on the limit hook will form a preliminary fixation, which not only helps to maintain the stability of the U-shaped tube, but also can further reduce the tolerance before welding. First, place the U-shaped tube on the limit hook, and use the arc body of the limit hook to achieve preliminary fixation. At this time, the fixing seat provides a stable supporting force for the limit hook. Then, the sleeve is driven by the lifting platform to move radially, and the position of the U-shaped tube is fine-tuned to reduce the gap and tolerance with the straight tube. After ensuring that the U-shaped tube and the straight tube are accurately aligned, the welding operation is performed. Since the tolerance has been reduced in the early stage through the cooperation of the limit assembly sleeve, the lifting platform and the limit hook, the welding effect is more stable and reliable. The entire combined operation mechanism effectively improves the stability of the equipment through the mutual cooperation of multiple components. During the welding process, each component can maintain a stable position and posture, thereby ensuring the consistency of welding quality.

[0035] Embodiment 1

[0036] like Figures 1 to 4 As shown, the embodiment of the present application provides a fixing device for welding a bicycle front fork, comprising a fixing assembly 100 and a limiting assembly 200;

[0037] The fixing assembly 100 serves as a positioning base for supporting and preliminarily fixing the bicycle front fork;

[0038] The fixing assembly 100 includes a support plate 110, a limit block 120, a straight tube 130, a fixing plate 140, a support seat 150 and a U-shaped tube 160;

[0039] The support plate 110 is a rectangular body, vertically installed on the ground, made of alloy steel, with good bearing capacity and stability, serving as the basic support of the entire device to ensure sufficient stability and load-bearing capacity;

[0040] The top of the support plate 110 is fixedly connected to the limiting block 120. The limiting block 120 is a rectangular body made of alloy steel with good wear resistance and heat resistance. There are four of them evenly distributed on the support plate 110 to limit the straight pipe 130.

[0041] The straight tubes 130 are cylindrical, two in number, and made of alloy steel, having good strength and rigidity, and are slidably connected to the inner wall side of the limit block 120 to achieve fine adjustment in the front-rear direction;

[0042] The bottom end of the support plate 110 in the length direction is fixedly connected with a fixing plate 140, which is a rectangular body, two in number, made of steel, has good bearing capacity and stability, and is arranged vertically with the support plate 110;

[0043] The inner wall side of the fixing plate 140 is fixedly connected with a support seat 150. The support seat 150 is a cylindrical body, two in number, made of steel, and has good bearing capacity and stability, and is used to support and fix the straight pipe 130.

[0044] The support seat 150 is connected to a U-shaped tube 160 at one side away from the support plate 110. The bottom of the U-shaped tube 160 is provided with a limiting assembly 200 for further fixing the front fork. The limiting assembly 200 is used to adjust and fix the bicycle front fork more precisely on the basis of the fixing assembly 100.

[0045] The limiting assembly 200 is used to perform more precise adjustment and fixation of the bicycle front fork on the basis of the fixing assembly 100;

[0046] The limiting assembly 200 includes a sleeve 210, a lifting platform 211, a fixing seat 220 and a limiting hook 221;

[0047] The bottom of the U-shaped tube 160 is slidably connected with a sleeve 210. The sleeve 210 is a cylindrical body, and there are two of them. The sleeve 210 can cover the bottom of the U-shaped tube 160. By adjusting the position of the sleeve 210, the gap between the U-shaped tube 160 and the straight tube 130 can be flexibly adjusted, thereby reducing the tolerance and improving the fixing accuracy. The sleeve 210 is made of alloy steel and has sufficient strength and durability.

[0048] The bottom of the sleeve 210 is fixedly connected with a lifting platform 211. The lifting platform 211 is a rectangular body made of alloy steel with good strength and wear resistance. The sleeve 210 can be driven to move radially through the lifting action to achieve more precise adjustment. After the initial fixation, the lifting platform 211 can be withdrawn to further reduce the tolerance and improve the welding quality.

[0049] The fixing seat 220 is fixedly connected to the middle of the front end surface of the support plate 110 near the inner wall of the straight tube 130 and is a rectangular structure. The fixing seat 220 is made of alloy steel and has sufficient strength and durability.

[0050] The fixing seat 220 is fixedly connected to a limiting hook 221 on one side of the fixing seat 220 away from the supporting plate 110. The limiting hook 221 is an arc-shaped body made of stainless steel with good strength and wear resistance. The top of the U-shaped tube 160 can be placed on the limiting hook 221 to form a preliminary fixation to prevent it from sliding or falling off.

[0051] The sleeve 210 abuts against the support seat 150;

[0052] There is a gap between the support seat 150 and the support plate 110;

[0053] There is a gap between the fixing plate 140 and the supporting seat 150;

[0054] The opening direction of the U-shaped tube 160 faces the sleeve 210 .

[0055] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0056] The sleeve 210 is used to cover the bottom of the U-shaped tube 160. By adjusting the sleeve 210, the gap between the U-shaped tube 160 and the straight tube 130 can be changed, which is very important for reducing the tolerance between the two. The bottom of the sleeve 210 is fixedly connected to the lifting platform 211. The movement of the lifting platform 211 will be directly transmitted to the sleeve 210. The lifting platform 211 can drive the sleeve 210 to move radially. The mobility enables the gap between the U-shaped tube 160 and the straight tube 130 to be further fine-tuned by adjusting the position of the sleeve 210 after the U-shaped tube 160 and the straight tube 130 are initially fixed. After the desired gap is reached and the straight tube 130 is initially fixed, the sleeve 210 can be adjusted to adjust the position of the sleeve 210. Afterwards, the lifting platform 211 can be removed, which helps to further reduce the tolerance. After the lifting platform 211 is removed, the connection between the sleeve 210 and the U-shaped tube 160 and the straight tube 130 will be more stable, and no additional gap or looseness will be generated due to the existence of the lifting platform 211. Reducing the tolerance is crucial to improving the stability and accuracy of the entire system. The size of the tolerance directly affects the fit between the components and the overall performance. Through the coordinated use of the sleeve 210 and the lifting platform 211, the gap between the U-shaped tube 160 and the straight tube 130 can be more effectively controlled, thereby improving the accuracy and reliability of the entire system.

[0057] Embodiment 2

[0058] In order to further improve the applicability and convenience of the use of the fixing device for welding a bicycle front fork of the present application, the embodiment of the present application optimizes and improves the limit assembly, specifically:

[0059] like Figure 5 The fixing seat 220 is fixedly connected to the middle of the front end surface of the support plate 110 near the inner wall of the straight tube 130 and is a rectangular structure. The fixing seat 220 is made of alloy steel and has sufficient strength and durability.

[0060] The fixing seat 220 is fixedly connected to a limiting hook 221 on one side of the fixing seat 220 away from the supporting plate 110. The limiting hook 221 is an arc-shaped body made of stainless steel with good strength and wear resistance. The top of the U-shaped tube 160 can be placed on the limiting hook 221 to form a preliminary fixation to prevent it from sliding or falling off.

[0061] The fixing seat 220 provides support for the limiting hook 221, so that the limiting hook 221 can bear the U-shaped tube 160 and the additional load that it may bear without deformation or displacement. The limiting hook 221 is an arc-shaped body, so that the limiting hook 221 matches the top shape of the U-shaped tube 160, which helps to better fix the U-shaped tube 160. When the top of the U-shaped tube 160 is placed on the limiting hook 221, the U-shaped tube 160 will be initially fixed. The initial fixation helps to maintain the stability of the U-shaped tube 160 in subsequent operations, which is convenient for further adjustment or fixation. The initial fixation of the U-shaped tube 160 by the hook 221 can further reduce the tolerance between the U-shaped tube 160 and other components. The limiting hook 221 can fit tightly against the top of the U-shaped tube 160, limiting the vertical movement of the U-shaped tube 160, thereby reducing the tolerance caused by the gap. Through precise adjustment and fixing mechanisms, the precise fit between the U-shaped tube 160 and other components can be ensured, thereby improving the stability and accuracy of the entire system, reducing tolerances, and helping to improve the operating efficiency of the mechanical system, reduce wear and failures, and thus extend the service life of the system.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
