Description

[0002] The front fork component of a bicycle is located in the front part of the bicycle structure. Its upper end is connected to the handlebar component, the frame component cooperates with the front tube, and the lower end cooperates with the front axle component to form the guidance system of the bicycle. By turning the handlebar and the front fork, the front wheel can change direction, which plays a guiding role in the bicycle. In addition, it can also control the driving of the bicycle. The force condition of the front fork component is that of a cantilever beam, so the front fork component must have sufficient strength and other properties.

[0003] The front fork component is often composed of a front fork and a vertical beam. During the production process of the front fork component, it is generally necessary to fix the front fork and the vertical beam, and then weld the two together using a welding gun installed at the end of a robotic arm, and flip the front fork and the vertical beam during welding. However, the robotic arm is prone to collision during welding, so the robotic arm needs to move with the flipping of the front fork and the vertical beam, which is rather troublesome. In order to reasonably improve this problem, the present application proposes a welding device for a bicycle front fork. Utility Model Content

However, since the robot arm is prone to collision during welding, the robot arm needs to move with the flipping of the front fork and the vertical beam, which is a rather troublesome technical problem.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0025] like Figure 1-Figure 4 As shown, a welding device for a bicycle front fork proposed in one embodiment of the present application includes:

[0026] A workbench 1 is provided with a fixing ring 2 on the top thereof. The fixing ring 2 stands vertically on the workbench 1. A mounting ring 3 is rotatably mounted inside the fixing ring 2. A welding mechanism 4 is mounted inside the mounting ring 3. The welding mechanism 4 is a welding gun, which is a prior art. The output end of the welding mechanism 4 extends out of the mounting ring 3. When the mounting ring 3 rotates, the welding mechanism 4 can be driven to move in a circular manner along the center of the mounting ring 3.

[0027] The mounting frames 5 are symmetrically arranged on the opposite sides of the fixing ring 2, and the mounting frames 5 are perpendicular to the workbench 1, and they are both slidably matched with the workbench 1. The bottom of the mounting frames 5 is slidably matched with the workbench 1, and the fixing ring 2 is located in the sliding direction of the two mounting frames 5. A driving member 6 is provided on the workbench 1, which is used to drive the two mounting frames 5 to slide. When the driving member 6 works, it can drive two. Fixing clamps 7 are provided on the opposite sides of the mounting frames 5. The fixing clamps 7 are existing pipe clamps. The remote ends of the front fork and the vertical beam can be inserted into the fixing clamps 7 and fixed therethrough. The two fixing clamps 7 fix the front fork and the vertical beam respectively. The two mounting frames 5 can be driven to move toward the fixing ring 2 by the driving member 6, so that the front fork and the vertical beam on the fixing clamps 7 can approach each other and make contact. Then, the contact ends thereof are located in the output direction of the welding mechanism 4;

[0028] A driving mechanism 8, which is used to drive the mounting ring 3 to rotate. The driving mechanism 8 can drive the mounting ring 3 to drive the welding mechanism 4 to rotate, so that the contacting part of the front fork and the vertical beam can be annularly welded;

[0029] The present application adopts the design of the mounting ring 3. After the front fork and the vertical beam are respectively fixed on the fixing clamp 7, the two mounting frames 5 can be driven by the driving member 6 to move toward the fixing ring 2 to make the front fork and the vertical beam close to each other. The front fork can pass through the mounting ring 3 and contact the vertical beam. Then, the mounting ring 3 can be driven to rotate by the driving mechanism 8, and the contacting parts of the front fork and the vertical beam can be annularly welded by the rotating welding mechanism 4. Compared with the prior art, the structure is simpler, more convenient and easier to use, and it is not easy to cause collision during the welding process, so it is practical.

[0030] like Figure 3 As shown, in some embodiments, the driving member 6 includes two screw rods 9 rotatably installed on the workbench 1, and the two screw rods 9 are respectively threadedly matched with the two mounting frames 5. When the screw rods 9 rotate, the mounting frames 5 can be driven to slide on the workbench 1. A rotating rod 10 is rotatably installed on the workbench 1. The axis of the rotating rod 10 is perpendicular to the axis of the screw rod 9, and its end is connected to the two screw rods 9 through a bevel gear assembly 11. The bevel gear assembly 11 includes a first bevel gear installed on the two screw rods 9 and a second bevel gear installed on the rotating rod 10. The two first bevel gears are meshed with the second bevel gear. When the rotating rod 10 rotates, the two first bevel gears can be driven to rotate synchronously in the opposite direction by the second bevel gear, so that the two mounting frames 5 can be driven to approach or move away from each other by the two screw rods 9. A first driving part 12 is provided on the workbench 1, which is used to drive the rotating rod 10 to rotate. The first driving part 12 is a motor, and its output end is connected to the rotating rod 10.

[0031] like Figure 1 and Figure 2 As shown, in some embodiments, the driving mechanism 8 includes a spur gear 13 rotatably mounted on the workbench 1, a through groove 14 is provided on the fixing ring 2, and a tooth groove 15 is provided on the outer side of the mounting ring 3. The spur gear 13 is meshed with the tooth groove 15 through the through groove 14. When the spur gear 13 rotates, the mounting ring 3 can be driven to rotate along its own axis through the tooth groove 15. A second driving part 16 is provided on the workbench 1, which is used to drive the spur gear 13 to rotate. The second driving part 16 is a motor, and its output end is connected to the spur gear 13.

[0032] like Figure 1 and Figure 2 As shown, in some embodiments, the fixing fixture 7 is connected to the mounting frame 5 via a buffer mechanism 17. The buffer mechanism 17 can reduce the rigid collision generated when the front fork and the vertical beam contact, making it less likely to be deformed and damaged.

[0033] like Figure 1 and Figure 2As shown, in some embodiments, the buffer mechanism 17 includes a guide column 18 constructed on one side of the fixing clamp 7, which is slidably matched with the mounting frame 5. The guide column 18 slides through the mounting frame 5 to guide the movement of the fixing clamp 7. The fixing clamp 7 and the mounting frame 5 are connected by a compression spring 19. The compression spring 19 is the abbreviation of a compression spring, which is used to provide a thrust for forcing the fixing clamp 7 to move away from the mounting frame 5. After the front fork and the vertical beam come into contact, as the mounting frame 5 continues to move, the compression spring 19 is compressed. On the one hand, it makes it difficult for the front fork and the vertical beam to produce a rigid collision and deformation and damage. On the other hand, under the resistance of the compression spring 19, the front fork and the vertical beam are tightly hinged, which can improve the welding effect of the two.

[0034] like Figure 3 As shown, in some embodiments, there are two welding mechanisms 4, which are arranged in a ring shape on the inner side of the mounting ring 3. With this design, when welding, the welding of the front fork and the vertical beam can be completed when the mounting ring 3 rotates half a circle. While reducing the stroke of the mounting ring 3, it can also effectively reduce the welding time and improve its production efficiency.

[0035] like Figure 3 and Figure 4 As shown, in some embodiments, a vacuum assembly 20 is provided on the fixing ring 2, and the output ends of the two welding mechanisms 4 are located in the vacuum direction of the vacuum assembly 20. The harmful gases generated by welding can be collected through the vacuum assembly 20 to prevent them from polluting the indoor environment.

[0036] like Figure 3 and Figure 4 As shown, in some embodiments, the vacuum assembly 20 includes an annular pipe 21 installed on one side of the fixed ring 2, the inner side of the annular pipe 21 is larger than the inner side of the mounting ring 3, and an annular opening 22 is provided thereon. The width of the annular opening 22 is relatively narrow, and the output ends of the two welding mechanisms 4 are located on the inner side of the annular opening 22. An air pump 23 is installed on the top of the fixed ring 2, which is connected to the annular pipe 21. The output end of the air pump 23 can be connected to a gas processing device. When the air pump 23 is working, the gas in the annular pipe 21 can be extracted. At this time, the outside air can carry harmful gases into the annular pipe 21 from the annular opening 22 and be discharged from the output end of the air pump 23.

[0037] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
