[0026] The following description, in conjunction with the accompanying drawings, describes a welding fixture for a side support according to an embodiment of the present invention.

[0027] This utility model aims to provide an embodiment of a welding fixture for a side support.

[0028] In the structure of the motorcycle's side stand, refer to Figure 1 The side support includes a round rod 340, accessory 1 350, accessory 2 360, and hinge joint 370. The round rod 340 has a foot 400. Accessories 1 350 and accessory 2 360 are welded to the radial outer surface of the round rod 340. The hinge joint 370 is welded to the end of the round rod 340 away from the foot 400. To ensure the support function of the side support, it is necessary to ensure that the relative positions of the round rod 340, accessory 1 350, accessory 2 360, and hinge joint 370 are correct.

[0029] A welding fixture for a side support according to an embodiment of this utility model, referring to... Figure 2 and Figure 3The system includes a first clamping mechanism, comprising a first support base 100, a second support base 120, a third support base 380, a fourth support base 150, a first positioning base 170, a first positioning assembly, and a first pressing assembly 390. The first support base 100 has a first positioning groove 110 at its top, which accommodates a round rod 340. The second support base 120 has a second positioning groove 130 at its top, which accommodates a first accessory 350, thus restricting the first accessory 350 to the radial outer surface of the round rod 340. The third support base 380 has a third positioning groove 140 at its top, which accommodates a second accessory 360, thus restricting the second accessory 360 to the radial outer surface of the round rod 340. Component 350 is constrained on the radial outer surface of the round rod 340; the top of the fourth support 150 is provided with a positioning surface 160, which is used to abut against the foot 400 of the round rod 340 to restrict the position of the foot 400 of the round rod 340; the top of the first positioning seat 170 is provided with a first positioning part 180, which is used to match the groove of the hinge joint 370 to restrict the relative position of the hinge joint 370 and the foot 400 of the round rod 340; the first positioning component can be inserted into the pin hole of the hinge joint 370 to restrict the movement of the hinge joint 370; the first clamping component 390 can move downward and cooperate with the first support 100 to clamp the round rod 340.

[0030] It is understood that this utility model, by setting a first support base 100, a second support base 120, a third support base 380, a fourth support base 150, a first positioning base 170, a first positioning assembly, and a first clamping assembly 390, places the round rod 340, accessory one 350, accessory two 360, and hinge joint 370 respectively in the first positioning groove 110, the second positioning groove 130, and the third positioning groove 140. Then, the foot 400 of the round rod 340 abuts against the positioning surface 160, and the groove of the hinge joint 370 matches the first positioning part 180, thus precisely restricting the hinge joint 370 and the round rod 340. The foot 400 is positioned, and the first positioning component is inserted into the pin hole of the hinge joint 370. The first clamping component 390 is used to clamp the round rod 340, preventing the hinge joint 370 and the round rod 340 from moving during the welding process. This achieves rapid, accurate positioning and reliable clamping of the motorcycle side bracket round rod 340, hinge joint 370, accessory one 350 and accessory two 360, ensuring that the relative positions of the foot 400 of the round rod 340, accessory one 350, accessory two 360 and hinge joint 370 are correct, improving the consistency of product welding and ensuring that the side bracket can perform its function after being installed on the motorcycle.

[0031] In some embodiments of this utility model, reference is made to Figure 4The first positioning seat 170 has a positioning hole 190 on its horizontal side. The first positioning component includes a first cylinder 200 and a positioning pin 210. The first cylinder 200 is used to drive the positioning pin 210 to move horizontally. After the positioning pin 210 passes through the pin hole of the hinge joint 370, it matches the positioning hole 190.

[0032] Understandably, the first cylinder 200 drives the positioning pin 210 to insert into the pin hole of the hinge joint 370. The positioning pin 210 eventually matches the positioning hole 190 on the positioning seat, thereby completely restricting the position of the hinge joint 370 in both horizontal and rotational degrees of freedom, ensuring high accuracy of the relative position between the hinge joint 370 and the foot 400 of the round rod 340.

[0033] In some embodiments of this utility model, a second positioning component is also included. The second positioning component includes a second cylinder 220 and a limiting block 230. The second cylinder 220 is used to drive the limiting block 230 to move horizontally. The bottom of the limiting block 230 can abut against the top of the hinge joint 370, so that the limiting block 230 and the first positioning seat 170 cooperate vertically to restrict the hinge joint 370.

[0034] Understandably, by using the second cylinder 220 to drive the limiting block 230 to move horizontally, the bottom of the limiting block 230 is positioned above the top of the hinge joint 370, so that the limiting block 230 and the first positioning seat 170 cooperate vertically to restrict the position of the hinge joint 370, preventing it from floating or shaking slightly due to heat or external force during the welding process, and further enhancing the stability and reliability of the clamping.

[0035] In some embodiments of this utility model, guide grooves 240 are provided on both horizontal sides of the first positioning seat 170, and guide strips 250 are provided on the limiting block 230. The guide strips 250 can move along the guide grooves 240 to limit the movement position of the limiting block 230.

[0036] Understandably, during the horizontal movement of the limit block 230, the guide bar 250 can move along the guide groove 240, which improves the repeatability of the limit block 230's movement, extends the service life of the cylinder and the limit block 230, and ensures the long-term stable and reliable operation of the mechanism.

[0037] In some embodiments of this utility model, a clamping assembly is also included. The clamping assembly includes a driving member 260 and an abutment block 270. The driving member 260 is used to drive the abutment block 270 to move horizontally. The abutment block 270 can drive the end of the round rod 340 away from the foot 400 to abut against the hinge joint 370.

[0038] Understandably, by horizontally pushing the abutment block 270 with the drive component 260, the end of the round rod 340 away from the foot 400 is tightly pressed against the mating surface of the hinge joint 370. This actively eliminates gaps between parts before welding, significantly improving the final welding accuracy and the overall integrity of the component.

[0039] In some embodiments of this utility model, the driving component 260 is a manual quick clamp, and the movable end of the manual quick clamp is connected to the abutment block 270. It is understood that compared with pneumatic or electric drives, the manual quick clamp has a simple structure, low cost, and convenient maintenance, and also takes into account both clamping reliability and ease of operation.

[0040] In some embodiments of this utility model, the abutment block 270 is provided with two guide portions 280 in a horizontal manner. The two guide portions 280 move along the horizontal sides of the fourth support base 150 respectively to limit the movement direction of the abutment block 270.

[0041] Understandably, during the horizontal movement of the abutment block 270, the two guide parts 280 move along the horizontal sides of the fourth support 150 respectively, ensuring that the thrust generated by the abutment block 270 is strictly in the horizontal direction and accurately pushes the end of the round rod toward the hinge joint 370.

[0042] In some embodiments of this utility model, two first support seats 100 are provided, and the two first support seats 100 are distributed along the length direction of the round rod 340. By using the two first support seats 100 to support the round rod 340, it is ensured that the round rod 340 remains straight and stable throughout the welding process, further improving the product quality and welding consistency.

[0043] In some embodiments of this utility model, the second support 120 is provided with a fourth positioning groove 290, which is used to accommodate the hemispherical portion of the accessory 350. Since the accessory 350 is a rod-shaped structure and its length is relatively small, by using the fourth positioning groove 290 to restrict the position of the hemispherical portion of the accessory 350, the position of the accessory 350 is not easily moved, thus preventing it from moving during welding.

[0044] In some embodiments of this utility model, a second clamping mechanism is further included. The second clamping mechanism includes: a fifth support base 300, with a fifth positioning groove at the top, which accommodates the round rod 340 after it has been flipped from the first clamping mechanism; a second positioning base 310, with a second positioning part at the top, which is used to match the groove of the hinge joint 370 to limit the position of the hinge joint 370; a third positioning component 320, which can be inserted into the pin hole of the hinge joint 370 to limit the movement of the hinge joint 370; and a second pressing component 330, which can move downward and cooperate with the fifth support base 300 and the second positioning base 310 to clamp the round rod 340.

[0045] Understandably, after all the welds on the front side are completed in the first set of fixtures, the workpiece is flipped over and placed on the second clamping mechanism, so that the round rod 340 is placed in the fifth positioning groove, the groove of the hinge joint 370 matches the second positioning part, then the third positioning component 320 is inserted into the pin hole of the hinge joint 370, and the second clamping component 330 cooperates with the fifth support seat 300 and the second positioning seat 310 to clamp the round rod 340, thereby completing the welding operation on the other side conveniently and with high precision, ensuring the integrity and reliability of the overall welding quality.
