Description

Technical Field

[0001] This utility model relates to the field of bicycle component technology, and in particular to a bicycle front fork and its assembly and welding mold. Background Technology

[0002] Bicycles, also known as pedal bikes or bicycles, are not only an environmentally friendly means of transportation for getting around, but also fitness equipment for cycling and outings, making them an important tool for people's daily lives.

[0003] A bicycle includes a frame, pedals, and a front fork. The front fork is connected to the frame's vertical tube and is used to mount the front wheel. In existing technology, the front fork is generally formed by welding together structures such as fork ribs, shoulder caps, vertical rods, and dropouts. The shoulder cap is cylindrical and mounted on the vertical rod. The fork ribs include the left and right fork legs, which need to be welded to the cylindrical shoulder cap to form a connection. Specifically, the connection point between the left and right fork legs is made into an arc-shaped butt joint using processes such as cutting and bending. The left and right fork legs are then joined to the arc-shaped shoulder cap through this arc-shaped butt joint, and then welded around the circumference of the joint to form a complete structure. Additionally, the dropouts need to be welded to the fork legs. Specifically, the left and right fork legs are each welded with a corresponding left and right dropout. The left and right dropouts are inserted into the left and right fork legs and then welded around the circumference of the joint to form a complete structure.

[0004] However, in the existing technology, the welded parts on the bicycle front fork will have obvious outward-protruding welds, which will result in discontinuous front fork shape, poor aesthetics, and thus affect the user's consumption experience. Utility Model Content

[0029] The beneficial effects of this utility model are:

[0030] This invention is designed based on the structure of a bicycle fork. Specifically, by creating a first gap between the top surface of the shoulder cover and the fork shoulder, a second gap between the first hook and the first fork leg, and a third gap between the second hook and the second fork leg, a first filler groove can be formed in the area between the shoulder cover and the top surface, a second filler groove can be formed in the area between the first hook and the first fork leg, and a third filler groove can be formed in the area between the second hook and the second fork leg. Thus, when a complete bicycle fork is welded, the welding material can be filled into the first, second, and third filler grooves without protruding outwards, resulting in a continuous shape and significantly improved aesthetics of the finished bicycle fork, thereby enhancing the user's consumer experience.

[0031] This invention utilizes a bicycle front fork welding mold for assembling bicycle front forks to be welded. Specifically, by controlling the distance between the first and second support blocks to equal a first preset value, this invention ensures that when the vertical rod is placed on the second support block, the depth to which the vertical rod is inserted into the insertion hole satisfies the distance between the top surfaces of the shoulder cap and the fork shoulder equal to the first distance, and that the shoulder cap and / or fork rib are not damaged. Furthermore, by controlling the distance between the third and first support blocks to equal a second preset value, this invention ensures that when the spool is placed on the third support block, the depth to which the first hook is inserted into the first fork leg satisfies the distance between the first hook and the first fork leg. The distance between the second hook and the second fork is equal to the second gap, and the first hook and / or the first fork leg will not be damaged. The depth of the second hook inserted into the second fork leg satisfies the requirement that the distance between the second hook and the second fork leg is equal to the third gap, and the second hook and / or the second fork leg will not be damaged. Thus, a first filler groove, a second filler groove, and a third filler groove can be formed on the assembled bicycle fork. After the complete bicycle fork is welded, the welding material is filled in the first filler groove, the second filler groove, and the third filler groove without protruding outwards. This makes the shape of the bicycle fork continuous and significantly improves its aesthetics, thereby enhancing the user's consumption experience. Attached Figure Description

[0051] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0052] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0053] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0054] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0055] Please see Figures 1 to 12 This embodiment provides a bicycle front fork, which includes a fork rib 110 and a vertical bar 120. The fork rib 110 includes a fork shoulder 111, a first fork leg 112 and a second fork leg 113. The fork shoulder 111, the first fork leg 112 and the second fork leg 113 are integrally formed. The fork shoulder 111 connects the first fork leg 112 and the second fork leg 113 together. The fork shoulder 111 is provided with a socket 1111. The first fork leg 112 and the second fork leg 113 are hollow.

[0056] The vertical rod 120 has a first insertion part 121 at one end along its axial direction. A shoulder cover 122 is provided on the vertical rod 120. The first insertion part 121 is inserted into the insertion hole 1111 from the top surface 1112 of the shoulder 111, with the shoulder cover 122 and the top surface 1112 facing each other. Specifically, the insertion hole 1111 extends axially to the top surface 1112 of the shoulder 111, forming a first opening 11121 on the top surface 1112 of the shoulder 111. The first insertion part 121 is inserted into the insertion hole 1111 through the first opening 11121, thereby enabling the vertical rod 120 and the fork 110 to be assembled together. Furthermore, along the axial direction of the vertical rod 120, the shoulder cover 122 and the top surface 1112 face each other. There is a first gap between the two. The area between the shoulder cover 122 and the top surface 1112 forms a first filler groove 161. When manufacturing the bicycle fork mentioned above, the first filler groove 161 can serve as the first welding point. During the welding process, the welding material fills the first filler groove 161. After welding around the entire circumference of the first filler groove 161, the vertical rod 120 and the fork 110 are welded together. Since the welding material fills the first filler groove 161 during the welding process, the weld is formed in the first filler groove 161 after welding and fills the first filler groove 161, so that the shape between the vertical rod 120 and the fork 110 is continuous and there is no protruding weld.

[0057] In addition to the fork 110 and the vertical bar 120, the bicycle fork also includes a first pawl 131 and a second pawl 132. The first pawl 131 has a second insertion portion 141 formed on it, and the second pawl 132 has a third insertion portion 142 formed on it. Based on the above description, the first fork leg 112 and the second fork leg 113 are hollow, so that the end of the first fork leg 112 away from the fork shoulder 111 forms a second opening 1121, and the end of the second fork leg 113 away from the fork shoulder forms a second opening 1121. One end of 111 forms a third opening 1131. The second insertion part 141 is inserted into the first fork 112 from the end of the first fork 112 away from the shoulder 111, that is, the second insertion part 141 is inserted into the first fork 112 through the second opening 1121. In addition, the third insertion part 142 is inserted into the second fork 113 from the end of the second fork 113 away from the shoulder 111, that is, the third insertion part 142 is inserted into the second fork 113 through the third opening 1131.

[0058] Furthermore, along the insertion direction of the second insertion portion 141, there is a second gap between the first hook 131 and the first fork leg 112, and along the insertion direction of the third insertion portion 142, there is a third gap between the second hook 132 and the second fork leg 113. The area between the first hook 131 and the first fork leg 112 forms a second filler groove 162. When manufacturing the bicycle fork described above, the second filler groove 162 can serve as a second welding point. During the welding process, welding material fills the second filler groove 162. Within 2, after welding around the entire circumference of the second filler groove 162, the fork 110 and the first hook 131 are welded together. Correspondingly, the area between the second hook 132 and the second fork 113 forms a third filler groove 163. When manufacturing the bicycle fork described above, the third filler groove 163 can serve as a third welding point. During the welding process, welding material is filled into the third filler groove 163. After welding around the entire circumference of the third filler groove 163, the fork 110 and the second hook 132 are welded together.

[0059] Since the welding material fills the second filler groove 162 and the third filler groove 163 during the welding process, the weld is formed in the second filler groove 162 and the third filler groove 163 after welding, and fills the second filler groove 162 and the third filler groove 163, so that the shape between the fork 110 and the first hook 131 and between the fork 110 and the second hook 132 is continuous, and no outwardly protruding weld appears.

[0060] Based on the above, this embodiment designs the structure of a bicycle fork. Specifically, this embodiment establishes a first gap between the top surface 1112 of the shoulder cover 122 and the fork shoulder 111, a second gap between the first hook 131 and the first fork leg 112, and a third gap between the second hook 132 and the second fork leg 113. This allows the area between the shoulder cover 122 and the top surface 1112 to form a first filler groove 161, the area between the first hook 131 and the first fork leg 112 to form a second filler groove 162, and the area between the second hook 132 and the second fork leg 113 to form a third filler groove 163. Thus, when a complete bicycle fork is welded, the welding material can be filled into the first filler groove 161, the second filler groove 162, and the third filler groove 163 without protruding outwards. This results in a continuous shape and significantly improved aesthetics of the manufactured bicycle fork, thereby enhancing the user's consumer experience.

[0061] Therefore, this embodiment also provides a method for assembling and welding a bicycle front fork as described above. The method for assembling and welding a bicycle front fork includes:

[0062] S1. Insert the first plug-in part 121 into the plug hole 1111, and insert the second plug-in part 141 and the third plug-in part 142 into the first fork leg 112 and the second fork leg 113 respectively. A first filler groove 161 is formed between the shoulder cover 122 and the top surface 1112, a second filler groove 162 is formed between the first hook 131 and the first fork leg 112, and a third filler groove 163 is formed between the second hook 132 and the second fork leg 113.

[0063] S2. Using the first filler groove 161 as the first welding point, weld the vertical rod 120 and the fork 110, and fill the first filler groove 161 with welding material; using the second filler groove 162 as the second welding point, weld the first hook 131 and the first fork 112, and fill the second filler groove 162 with welding material; using the third filler groove 163 as the third welding point, weld the second hook 132 and the second fork 113, and fill the third filler groove 163 with welding material.

[0064] Specifically, the fork 110, the vertical rod 120, the first hook 131, and the second hook 132 are all integrally formed. After the fork 110, the vertical rod 120, the first hook 131, and the second hook 132 are formed, the first insertion part 121 is inserted into the insertion hole 1111, and the second insertion part 141 and the third insertion part 142 are respectively inserted into the first fork leg 112 and the second fork leg 113, thereby assembling the bicycle front fork. Then, a first filler weld is formed between the shoulder cover 122 and the top surface 1112. The bicycle fork is made by welding the groove 161, the second filler groove 162 formed between the first hook 131 and the first fork leg 112, and the third filler groove 163 formed between the second hook 132 and the second fork leg 113. Since the welding material can be filled into the first filler groove 161, the second filler groove 162 and the third filler groove 163 during the welding process without protruding outward, the bicycle fork has a continuous shape and its aesthetics are significantly improved, thereby improving the user's consumption experience.

[0065] It is understood that laser welding, arc welding, or ultrasonic welding can be used during welding, and this embodiment does not impose any specific restrictions on these processes.

[0066] Furthermore, to ensure a first gap between the shoulder cover 122 and the top surface 1112, and to prevent the vertical rod 120 from protruding from the bottom of the shoulder 111 into the fork rib 110, in this embodiment, a first limiting groove 11111 is provided in the wall of the insertion hole 1111, and a limiting block 123 is provided on the vertical rod 120. The limiting block 123 is located on the side of the shoulder cover 122 facing the first insertion portion 121. It can be understood that the first limiting groove 11111 is formed by the top surface of the shoulder 111. 1112 is opened towards the bottom of the shoulder 111, thereby allowing the limiting block 123 to extend into the insertion hole 1111 and abut against the bottom of the first limiting groove 11111 along the axial direction of the vertical rod 120. The first limiting groove 11111 can limit the depth of the vertical rod 120 inserted into the shoulder 111, thereby ensuring that the vertical rod 120 will not be exposed from the bottom of the shoulder 111 to the fork bone 110, and also ensuring that there is a first gap between the shoulder cover 122 and the top surface 1112.

[0067] Furthermore, along the radial direction of the vertical rod 120, a second limiting groove 1231 is provided on the outer side of the limiting block 123. When the limiting block 123 extends into the insertion hole 1111, along the axial direction of the vertical rod 120, the bottom of the second limiting groove 1231 abuts against the top surface 1112, thereby ensuring that the distance between the shoulder cover 122 and the top surface 1112 is precisely equal to the preset value, and further ensuring that the vertical rod 120 will not be exposed from the bottom of the fork shoulder 111 to the fork bone 110.

[0068] In addition, to ensure a second gap between the first claw 131 and the first fork 112, in this embodiment, the cross-sectional area of ​​the first fork 112 gradually decreases from the side closer to the fork shoulder 111 to the side farther from the fork shoulder 111, while the cross-sectional area of ​​the second insertion part 141 remains unchanged from the side closer to the first claw 131 to the side farther from the first claw 131. This makes the second insertion part 141 blocked after being partially inserted into the first fork 112 and unable to continue to be inserted. That is, this embodiment can ensure a second gap between the first claw 131 and the first fork 112 by limiting the depth of the second insertion part 141 inserted into the first fork 112.

[0069] Of course, in other alternative embodiments, the cross-sectional area of ​​the second insertion part 141 may also gradually decrease from the side closer to the first hook 131 to the side farther away from the first hook 131, thereby also limiting the depth of the second insertion part 141 inserted into the first fork leg 112. This embodiment does not impose specific limitations on this.

[0070] Accordingly, to ensure a third gap between the second hook 132 and the second fork 113, in this embodiment, the cross-sectional area of ​​the second fork 113 gradually decreases from the side closer to the fork shoulder 111 to the side farther from the fork shoulder 111, while the cross-sectional area of ​​the third insertion part 142 remains unchanged from the side closer to the second hook 132 to the side farther from the second hook 132. This prevents the third insertion part 142 from being inserted further into the second fork 113 after a portion of it has been inserted. In other words, this embodiment can ensure a third gap between the second hook 132 and the second fork 113 by limiting the depth of the third insertion part 142 inserted into the second fork 113.

[0071] Of course, in other alternative embodiments, the cross-sectional area of ​​the third insertion part 142 may also gradually decrease from the side closer to the second hook 132 to the side farther away from the second hook 132, thereby also limiting the depth of the third insertion part 142 inserted into the second fork leg 113. This embodiment does not impose specific limitations on this.

[0072] Additionally, it is worth noting that a cylindrical shaft 150 is installed between the first hook 131 and the second hook 132, and the cylindrical shaft 150 is used to install the front wheel.

[0073] From the above, such as Figures 13 to 16 As shown, and in combination Figures 1 to 12 This embodiment also provides a bicycle front fork assembly welding mold, which is used to assemble a bicycle front fork to be welded. The bicycle front fork assembly welding mold includes a first support block 210, a second support block 220 and a third support block 230. The first support block 210 is used to place and position the fork rib 110, the second support block 220 is used to place and position the vertical rod 120, and the third support block 230 is used to place and position the spool 150 installed between the first hook 131 and the second hook 132, thereby positioning the first hook 131 and the second hook 132.

[0074] Specifically, the first support block 210 is provided with a first contour groove 211 and a second contour groove 212 arranged at intervals along a first direction. The first contour groove 211 is adapted to the first fork leg 112, and the second contour groove 212 is adapted to the second fork leg 113. The first fork leg 112 and the second fork leg 113 can be placed in the first contour groove 211 and the second contour groove 212 respectively in an arrangement at intervals along the first direction, thereby positioning the fork bone 110.

[0075] The second support block 220 is spaced apart from the first support block 210 along the second direction, which is perpendicular to the first direction. The distance between the first support block 210 and the second support block 220 is equal to a first preset value. The second support block 220 is provided with a third contour groove 221, which is adapted to the vertical rod 120. The vertical rod 120 can be placed in the third contour groove 221 and is in an axial position parallel to the second direction. When the vertical rod 120 is placed on the second support block 220, the vertical rod... The rod 120 is inserted into the socket 1111 to position the vertical rod 120. In this embodiment, by controlling the distance between the first support block 210 and the second support block 220, it is ensured that when the fork bone 110 and the vertical rod 120 are respectively placed on the first support block 210 and the second support block 220, the depth of the vertical rod 120 inserted into the socket 1111 is such that the distance between the top surface 1112 of the shoulder cover 122 and the fork shoulder 111 is equal to the first distance, and the shoulder cover 122 and / or the fork bone 110 will not be damaged.

[0076] Furthermore, the third support block 230 is spaced apart from the first support block 210 along the second direction, and the distance between the first support block 210 and the third support block 230 is equal to a second preset value. It can be understood that the third support block 230 and the second support block 220 are located on opposite sides of the first support block 210 along the second direction. The third support block 230 is provided with a fourth contour groove 231, which is adapted to the cylindrical shaft 150 installed between the first hook 131 and the second hook 132. The cylindrical shaft 150 installed between the first hook 131 and the second hook 132 can be placed in the fourth contour groove 231. When the cylindrical shaft 150 is placed on the third support block 230, the second insertion part 141 and the third insertion part 142... Do not insert the first fork 112 and the second fork 113 to position the first hook 131 and the second hook 132. In this embodiment, by controlling the distance between the third support block 230 and the first support block 210, it is ensured that when the cylinder shaft 150 is placed on the third support block 230, the depth to which the first hook 131 is inserted into the first fork 112 is such that the distance between the first hook 131 and the first fork 112 is equal to the second distance, and the first hook 131 and / or the first fork 112 will not be damaged. The depth to which the second hook 132 is inserted into the second fork 113 is such that the distance between the second hook 132 and the second fork 113 is equal to the third distance, and the second hook 132 and / or the second fork 113 will not be damaged.

[0077] Specifically, based on the structural design of the bicycle front fork, the third contour groove 221 penetrates the second support block 220 along the second direction, the fourth contour groove 231 penetrates the third support block 230 along the first direction, the vertical rod 120 is placed on the second support block 220 with its axis parallel to the second direction, and the spool 150 is placed on the third support block 230 with its axis parallel to the first direction. When the fork rib 110, the vertical rod 120, and the spool 150 are respectively placed on the first support block 210, the second support block 220, and the third support block 230, the fork rib 110, the vertical rod 120, and the spool 150... When assembled, in this embodiment, the first direction is the X-axis direction and the second direction is the Y-axis direction. When the fork 110 is placed on the first support block 210, the fork 110 is positioned in the X-axis direction, the Y-axis direction and the Z-axis direction perpendicular to the X-axis direction and the Y-axis direction. When the vertical rod 120 is placed on the second support block 220, the vertical rod 120 is positioned in the X-axis direction, the Y-axis direction and the Z-axis direction. When the cylindrical shaft 150 is placed on the third support block 230, the first hook 131 and the second hook 132 are positioned in the X-axis direction, the Y-axis direction and the Z-axis direction.

[0078] Furthermore, this embodiment controls the distance between the first support block 210 and the second support block 220 to be equal to a first preset value, thereby ensuring that when the vertical rod 120 is placed on the second support block 220, the depth to which the vertical rod 120 is inserted into the insertion hole 1111 is such that the distance between the top surface 1112 of the shoulder cover 122 and the fork shoulder 111 is equal to the first distance, and the shoulder cover 122 and / or the fork bone 110 will not be damaged. This embodiment also controls the distance between the third support block 230 and the first support block 210 to be equal to a second preset value, thereby ensuring that when the cylinder shaft 150 is placed on the third support block 230, the depth to which the first hook 131 is inserted into the first fork leg 112 is such that the distance between the first hook 131 and the first fork leg 112 is equal to the second distance, and... The first hook 131 and / or the first fork leg 112 will not be damaged. The second hook 132 is inserted into the second fork leg 113 to a depth that makes the distance between the second hook 132 and the second fork leg 113 equal to the third distance, and the second hook 132 and / or the second fork leg 113 will not be damaged. Thus, the first filler groove 161, the second filler groove 162 and the third filler groove 163 can be formed on the assembled bicycle fork. After the complete bicycle fork is welded, the welding material is filled in the first filler groove 161, the second filler groove 162 and the third filler groove 163 without protruding outwards. This makes the shape of the bicycle fork continuous and significantly improves its aesthetics, thereby improving the user's consumption experience.

[0079] It is worth noting that the first support block 210 includes a first block 213 and a second block 214 arranged at intervals along the second direction. The first block 213 is provided with a first groove 2111 and a second groove 2121 arranged at intervals along the first direction. The second block 214 is provided with a third groove 2112 and a fourth groove 2122 arranged at intervals along the first direction. The first groove 2111 and the third groove 2112 are arranged on the same side and form a first contour groove 211. The second groove 2121 and the fourth groove 2122 are arranged on the same side and form a second contour groove 212, thereby further ensuring that the flanking bone 110 is accurately positioned in the X-axis and Y-axis directions.

[0080] In addition, the positions of the first support block 210, the second support block 220, and the third support block 230 in the second direction are all adjustable. That is, in this embodiment, the distance between the first support block 210 and the second support block 220 and the distance between the first support block 210 and the third support block 230 are adjusted to ensure that the distance between the first support block 210 and the second support block 220 is precisely equal to the first preset value, and the distance between the first support block 210 and the third support block 230 is precisely equal to the second preset value. This ensures that when the fork rib 110, the vertical rod 120, and the cylinder shaft 150 are respectively placed on the first support block 210, the second support block 220, and the third support block 230, the assembled bicycle fork can form the first filler groove 161, the second filler groove 162, and the third filler groove 163 that meet the requirements.

[0081] It is understood that in this embodiment, the positions of the first support block 210, the second support block 220, and the third support block 230 in the second direction are adjusted only before a batch of bicycle forks are welded together. This ensures that each time the fork rib 110, the vertical rod 120, and the thru-axle 150 are placed, the distance between the top surface 1112 of the shoulder cover 122 and the fork shoulder 111 is equal to the first distance, the distance between the first hook 131 and the first fork leg 112 is equal to the second distance, and the distance between the second hook 132 and the second fork leg 113 is equal to the third distance. This ensures that the quality of the bicycle forks produced in the same batch is consistent and meets the requirements.

[0082] Based on the above, the bicycle front fork welding mold also includes a base 260. The first support block 210, the second support block 220, and the third support block 230 are all installed on the base 260. For example, in this embodiment, the base 260 is provided with a slide groove 261 extending in the second direction. The first support block 210, the second support block 220, and the third support block 230 can be detachably installed in the slide groove 261. When it is necessary to adjust the position of the first support block 210, the second support block 220, and the third support block 230, the connection of the first support block 210, the second support block 220, and the third support block 230 can be disconnected first, and then the position of the first support block 210, the second support block 220, and the third support block 230 relative to the slide groove 261 can be adjusted. After the adjustment is completed, the first support block 210, the second support block 220, and the third support block 230 can be locked and installed in the slide groove 261 again.

[0083] Furthermore, the bicycle front fork welding mold also includes a first clamping mechanism 240 and a second clamping mechanism 250. The first clamping mechanism 240 is configured to clamp and lock the vertical rod 120 onto the second support block 220, thereby fully positioning the vertical rod 120 in the Z-axis direction. The second clamping mechanism 250 is configured to clamp and lock the thru-axle 150 onto the third support block 230, thereby fully positioning the thru-axle 150 in the Z-axis direction.

[0084] Specifically, the first pressing mechanism 240 includes a first driving member 241 and a first pressing block 242. The first driving member 241 is configured to drive the first pressing block 242 to move toward or away from the second support block 220. The first pressing block 242 is provided with a fifth contour groove 2421. After the first pressing block 242 moves toward the second support block 220, the groove wall of the fifth contour groove 2421 can cover the vertical rod 120 together with the groove wall of the third contour groove 221, thereby pressing and locking the vertical rod 120 onto the second support block 220.

[0085] The second pressing mechanism 250 includes a second driving member 251 and a second pressing block 252. The second driving member 251 is configured to drive the second pressing block 252 to move toward or away from the third support block 230. The second pressing block 252 is provided with a sixth contour groove 2521. The groove wall of the sixth contour groove 2521 can cover the cylinder shaft 150 together with the groove wall of the fourth contour groove 231, thereby pressing and locking the cylinder shaft 150 onto the third support block 230.

[0086] For example, in this embodiment, both the first driving member 241 and the second driving member 251 are elbow clamps. Of course, in other optional embodiments, the first driving member 241 and the second driving member 251 may also be linear drive structures such as cylinders or electric cylinders. This embodiment does not impose specific limitations on this.

[0087] Based on the foregoing, after the fork 110, vertical rod 120, and thru-axle 150 are respectively placed on the first support block 210, the second support block 220, and the third support block 230, the area between the shoulder cover 122 and the top surface 1112 of the fork shoulder 111 is the first welding area, and the area between the first hook 131 and the first fork leg 112, as well as the area between the second hook 132 and the second fork leg 113, are the second welding areas. During welding, welding needs to be performed sequentially in the first and second welding areas. However, due to the relatively long overall length of the bicycle fork, to facilitate welding in the first and second welding areas sequentially... Welding is performed in the welding area. In this embodiment, the bicycle front fork welding mold also includes a third driving component (not shown in the figure). The third driving component is configured to drive the base 260 to move so that the first welding area and the second welding area are located in the welding station in sequence. That is, in this embodiment, the positions of the first welding area and the second welding area can be exchanged by the third driving component, so that welding can be performed in the first welding area and the second welding area in sequence. Since this embodiment does not require the welding gun to move between the first welding area and the second welding area, this embodiment can save the time consumed in the welding process, thereby improving production efficiency.

[0088] It is understood that the third driving component may be a rotary cylinder or a motor, etc., and this embodiment does not impose specific restrictions on it.

[0089] Furthermore, since the specific structure of the third driving component and the transmission connection structure between the third driving component and the base 260 are existing technologies, this embodiment will not elaborate on them.
