Description

Technical Field

[0001] This utility model relates to the field of motorcycle manufacturing technology, and in particular to a main bracket welding fixture. Background Technology

[0002] Motorcycles and electric bicycles typically have a main stand, usually located in the lower middle of the vehicle, serving as the primary support for stable parking. Existing main stands are generally rotatably connected to the underside of the vehicle, with a spring connecting them to retract and fold the main stand close to the underside. In use, the main stand is pushed open with the foot, leveraging leverage to lift the rear wheel off the ground, allowing the vehicle to stand independently and vertically, facilitating daily parking, cleaning, or simple maintenance. Compared to side stands, main stands provide more stable support, effectively preventing the vehicle from tipping over and avoiding tire deformation or vehicle imbalance that can occur with prolonged side parking. The main stand generally consists of support legs and a connecting frame. During production, the support legs need to be welded to the connecting frame. Current welding processes are prone to relative displacement between the support legs and the connecting frame, affecting welding quality and consistency. In severe cases, this can lead to uneven support legs and breakage at the weld between the support legs and the connecting frame, seriously impacting the quality of the finished product. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a main support welding fixture that prevents relative displacement between the support legs and the connecting frame during the welding process, thereby improving welding quality.

[0004] A main support welding fixture according to an embodiment of the present utility model includes: The connecting bracket placement seat includes a locking buckle, which is used to restrict the position of the connecting bracket; A connecting frame limiting mechanism is arranged around the periphery of the connecting frame placement seat. The connecting frame limiting mechanism includes a first pushing component, which is used to push the connecting frame to the locking buckle side. Support leg holder, used to hold the support legs; The second jacking component is located on the side of the connecting frame placement seat away from the first jacking component, and the output end of the second jacking component is connected to the support foot placement seat.

[0005] A main support welding fixture according to an embodiment of the present utility model has at least the following beneficial effects: During processing, the connecting frame to be welded is first placed on the connecting frame placement seat. Then, a pushing force is applied to the periphery of the connecting frame using a connecting frame limiting mechanism. The connecting frame limiting mechanism and the connecting frame placement seat cooperate to fix the position of the connecting frame to be welded. Next, the support leg to be welded is placed on the support leg placement seat. Then, the second pushing component drives the support leg placement seat to move backward. During the backward movement of the support leg placement seat, the support leg to be welded moves backward and pushes the support leg to be welded to the front of the connecting frame to be welded, so that the support leg to be welded and the connecting frame to be welded are tightly fitted and fixedly connected. Finally, the connection between the support leg and the connecting frame is welded manually or mechanically. The connecting frame to be welded is fixedly placed using the connecting frame placement seat, and the support leg to be welded is fixedly placed using the support leg placement seat. The second pushing component drives the support leg placement seat to move backward and continuously pushes the support leg placement seat, so that the support leg to be welded continuously pushes the connecting frame to be welded, thereby fixing the relative position of the support leg to be welded and the connecting frame to be welded, so as to carry out the welding process. The inverted L-shaped locking buckle locks and limits the connection frame to be welded, restricting its forward movement and further improving the reliability and stability of the connection frame's position. Compared to existing technologies, this method reduces the likelihood of relative displacement between the support legs and the connection frame during the welding process to form the main support, avoiding defects such as uneven support legs or weld breaks between the support legs and the connection frame. This improves the consistency of each weld, enhances welding quality, and ultimately improves the overall production quality of the main support.

[0022] The main frame of motorcycles and electric bicycles generally consists of a support leg 900 and a connecting frame 800. During production, the support leg 900 needs to be welded to the connecting frame 800 to obtain the main frame workpiece. In existing welding processes, relative displacement between the support leg 900 and the connecting frame 800 is prone to occur, affecting welding quality and the consistency of each weld. In severe cases, it can lead to unevenness of the support leg 900 and breakage at the weld between the support leg 900 and the connecting frame 800, seriously impacting the quality of the finished product.

[0023] Reference Figures 1 to 4 This utility model provides a main support welding fixture, including a connecting frame placement seat 100, a connecting frame limiting mechanism, a support foot placement seat 600, and a second pushing assembly 300. The connecting frame placement seat 100 includes a locking buckle 110, which is used to limit the position of the connecting frame 800. The connecting frame placement seat 100 is used to place the connecting frame 800 to be welded. The connecting frame limiting mechanism is arranged around the periphery of the connecting frame placement seat 100. The connecting frame limiting mechanism includes a first pushing assembly 200, which is used to push the connecting frame 800 to the side of the locking buckle 110. The connecting frame limiting mechanism can apply a pushing force to the periphery of the connecting frame 800. The connecting frame limiting mechanism and the connecting frame placement seat 100 cooperate to fix the position of the connecting frame 800 to be welded. Specifically, refer to... Figure 1 The locking buckle 110 is located on the upper part of the connecting frame placement seat 100. The locking buckle 110 has an inverted L-shaped structure, and the upper part of the locking buckle 110 extends backward. The first pushing component 200 can push the connecting frame 800 to be welded to the rear side of the locking buckle 110. The locking buckle 110 is used to lock and limit the connecting frame 800 to be welded, further improving the stability of the connecting frame 800 after the position is fixed.

[0024] The support leg placement seat 600 can fix the support leg 900 to be welded, thereby fixing the position of the support leg 900 to be welded; the second push assembly 300 is disposed on the side of the connecting frame placement seat 100 away from the first push assembly 200, as shown in the figure. Figure 1 The second pushing component 300 is disposed on the front side of the connecting frame placement seat 100, and the output end of the second pushing component 300 is connected to the support foot placement seat 600. Specifically, the second pushing component 300 can drive the support foot placement seat 600 to move in the front and back direction to push the support foot 900 placed on the support foot placement seat 600 to the front side of the connecting frame 800, and can continuously push the support foot placement seat 600 to achieve a continuous relative position fixation between the support foot 900 to be welded and the connecting frame 800 to be welded, so as to carry out the welding process.

[0025] During processing, the connecting frame 800 to be welded is first placed on the connecting frame placement seat 100. Then, the connecting frame limiting mechanism applies a pushing force to the periphery of the connecting frame 800. The connecting frame limiting mechanism and the connecting frame placement seat 100 cooperate to fix the position of the connecting frame 800 to be welded. Then, the support leg 900 to be welded is placed on the support leg placement seat 600. Then, the second pushing component 300 drives the support leg placement seat 600 to move backward. During the backward movement, the support leg placement seat 600 drives the support leg 900 to be welded to move backward and pushes the support leg 900 to be welded to the front side of the connecting frame 800 to be welded, so that the support leg 900 to be welded and the connecting frame 800 to be welded are tightly fitted and fixedly connected. Finally, the connection between the support leg 900 and the connecting frame 800 is welded manually or mechanically. The connecting frame 800 to be welded is fixedly placed using the connecting frame placement seat 100, and the support leg 900 to be welded is fixedly placed using the support leg placement seat 600. The second pushing component 300 drives the support leg placement seat 600 to move backward and continuously pushes the support leg placement seat 600, so that the support leg 900 to be welded continuously pushes the connecting frame 800 to be welded, thereby achieving a continuous relative position fixation between the support leg 900 to be welded and the connecting frame 800 to be welded, so as to carry out the welding process. The inverted L-shaped locking buckle 110 locks and limits the connecting frame 800 to be welded, restricting the forward movement of the connecting frame 800 to be welded, further improving the reliability and stability of the position fixation of the connecting frame 800. Compared with existing technologies, the process of welding the support leg 900 and the connecting frame 800 into the main support is less likely to cause relative displacement between the support leg 900 and the connecting frame 800, thus avoiding defects such as unevenness of the support leg 900 and breakage at the weld between the support leg 900 and the connecting frame 800, improving welding quality and consistency of each weld.

[0026] As a preferred option, refer to Figure 1 The connecting bracket placement seat 100 is provided with a limiting groove 120, which matches the lower side of the connecting bracket 800. By using the limiting groove 120 to match and limit the lower side of the connecting bracket 800, the effect of fixing the position of the connecting bracket 800 is further improved.

[0027] According to some embodiments of this application, refer to Figure 1 , Figure 3 and Figure 4The first pushing assembly 200 includes a first cylinder 210 and a first pushing block 220. The first pushing block 220 is connected to the piston rod of the first cylinder 210, and the first pushing block 220 can be matched and connected to the connecting frame 800. The first cylinder 210 can drive the first pushing block 220 to move towards the connecting frame placement seat 100. When the connecting frame 800 is placed on the connecting frame placement seat 100, the first pushing block 220 can be pushed to the side of the connecting frame 800, and push the connecting frame 800 to the side of the locking buckle 110.

[0028] As a preferred option, refer to Figure 1 and Figure 2 The connecting frame 800 has an inclined portion on its rear side, and the connecting frame placement seat 100 is also provided with a limiting protrusion 130, which is also inclined and matches the lower surface of the inclined portion on the rear side of the connecting frame 800; the front end of the first push block 220, that is, the end of the first push block 220 near the connecting frame placement seat 100, is provided with an abutment portion 230, as shown in the figure. Figure 2 The abutment portion 230 has a cylindrical structure when viewed from the right. When the first cylinder 210 drives the first push block 220 to move toward the connecting frame placement seat 100, the abutment portion 230 can press against the upper surface of the inclined portion on the rear side of the connecting frame 800. At this time, the limiting protrusion 130 can support the lower surface of the inclined portion on the rear side of the connecting frame 800, thereby clamping and fixing the upper and lower surfaces of the inclined portion on the rear side of the connecting frame 800, further improving the reliability of the position fixation of the connecting frame 800.

[0029] Furthermore, referring to Figure 1 , Figure 3 and Figure 4 The first pushing assembly 200 also includes a first connecting seat 240. A first cylinder 210 is fixedly connected to the first connecting seat 240. The first connecting seat 240 has a through hole, and a first pushing block 220 is movably inserted into the through hole of the first connecting seat 240. Specifically, the through hole of the first connecting seat 240 and the first pushing block 220 are connected with a clearance fit. The first connecting seat 240 can be used to fix the first cylinder 210, and the through hole of the first connecting seat 240 can also be used to limit the radial movement of the first pushing block 220 (see reference). Figure 1 The first push block 220 moves more precisely and smoothly along the front-back direction (with the front-back direction as the axis).

[0030] According to some embodiments of this application, refer to Figure 1 , Figure 3 and Figure 4The connecting frame limiting mechanism also includes a third pushing component 400 and a fourth pushing component 500. The third pushing component 400 and the fourth pushing component 500 are respectively disposed on opposite sides of the connecting frame placement seat 100. The third pushing component 400 and the fourth pushing component 500 cooperate to push the opposite sides of the connecting frame 800. By utilizing the cooperation of the third pushing component 400 and the fourth pushing component 500, the opposite sides of the connecting frame 800 are pushed, further limiting the position of the connecting frame 800 and further preventing the connecting frame 800 from shaking.

[0031] Furthermore, the third pushing assembly 400 includes a third cylinder 410 and a third pushing block 420, with the first pushing block 220 connected to the piston rod of the third cylinder 410; the fourth pushing assembly 500 includes a fourth cylinder 510 and a fourth pushing block 520, with the fourth pushing block 520 connected to the piston rod of the fourth cylinder 510. The third cylinder 410 can drive the third pushing block 420 to move towards the connecting frame placement seat 100, and the fourth cylinder 510 can drive the fourth pushing block 520 to move towards the connecting frame placement seat 100. The pushing directions of the third pushing block 420 and the fourth pushing block 520 are opposite. When the connecting frame 800 is placed on the connecting frame placement seat 100, the third pushing block 420 and the fourth pushing block 520 can push on opposite sides of the connecting frame 800, preventing the connecting frame 800 from shaking.

[0032] Furthermore, the extension and retraction direction of the piston rod of the third cylinder 410 is aligned with the extension and retraction direction of the piston rod of the fourth cylinder 510, while the extension and retraction direction of the piston rod of the first cylinder 210 is perpendicular to the extension and retraction direction of the piston rod of the third cylinder 410. Specifically, refer to... Figure 1 The piston rods of the third cylinder 410 and the fourth cylinder 510 extend and retract in the left-right direction, while the piston rod of the first cylinder 210 extends and retracts in the front-back direction. This allows for forward, left-right pushing of the connecting frame 800 placed on the connecting frame mounting base 100. Combined with the rearward reaction force of the locking buckle 110, this achieves the pushing, pressing, and fixing of the connecting frame 800 on all four sides.

[0033] It is understood that, in some other embodiments, reference is made to... Figure 1 The third pushing assembly 400 also includes a third connecting seat 430. The third cylinder 410 is fixedly connected to the third connecting seat 430. The third connecting seat 430 is also provided with a through hole. The third pushing block 420 is movably inserted into the through hole of the third connecting seat 430. The through hole of the third connecting seat 430 and the third pushing block 420 are connected with a clearance fit. The third connecting seat 430 can be used to fix the third cylinder 410, and the through hole of the third connecting seat 430 can also be used to limit the radial movement of the third pushing block 420 (see reference). Figure 1The third push block 420 moves more precisely and smoothly along the left and right directions (with the left and right directions as the axis).

[0034] It is understood that, in some other embodiments, reference is made to... Figure 1 The fourth pushing assembly 500 also includes a fourth connecting seat 530. The fourth cylinder 510 is fixedly connected to the fourth connecting seat 530. The fourth connecting seat 530 is also provided with a through hole. The fourth pushing block 520 is movably inserted into the through hole of the fourth connecting seat 530. The through hole of the fourth connecting seat 530 and the fourth pushing block 520 are connected with a clearance fit. The fourth connecting seat 530 can be used to fix the fourth cylinder 510, and the through hole of the fourth connecting seat 530 can also be used to limit the radial movement of the fourth pushing block 520 (see reference). Figure 1 The fourth push block 520 moves more precisely and smoothly along the left and right directions (with the left and right directions as the axis).

[0035] It is understood that, in some other embodiments, reference is made to... Figure 3 and Figure 4 A limiting ring 440 is also sleeved around the periphery of the third pushing block 420, and the limiting ring 440 is fixedly connected to the third pushing block 420. The limiting ring 440 is used to limit the stroke of the third pushing block 420, as shown in the figure. Figure 3 When the third push block 420 moves to the left, the limiting ring 440 can limit the leftward movement of the third push block 420; see reference. Figure 4 When the third push block 420 moves to the right, the limiting ring 440 restricts the rightward movement of the third push block 420. By limiting the rightward movement of the third push block 420, the limiting ring 440 prevents the third push block 420 from excessively pushing the connecting frame 800 to the right. In use, under the action of the limiting ring 440, the third cylinder 410 first drives the third push block 420 to push the connecting frame 800 to the right to the designated position, and then the fourth cylinder 510 drives the fourth push block 520 to push to the left to press the connecting frame 800, thus achieving the pressing and fixing of the connecting frame 800. This also ensures that the connecting frame 800 is positioned in the same location during each operation, improving the consistency of the relative position between the connecting frame 800 and the support leg 900 during each operation.

[0036] According to some embodiments of this application, refer to Figures 1 to 4 The support foot holder 600 includes multiple placement slots 610, each of which can be matched and connected to a support foot 900. Specifically, the support foot holder 600 includes two placement slots 610, which are located on the upper part of the support foot holder 600, and the length directions of the two placement slots 610 are not parallel. See also... Figure 3 and Figure 4The two placement slots 610 are arranged symmetrically in the front-back direction with respect to their axis mirror plane, and the length direction of the placement slots 610 intersects the extension and retraction direction of the piston rod of the second cylinder 310. The placement slots 610 facilitate the placement of the support foot 900, fix the support foot 900 in the horizontal direction, and facilitate the application of thrust when the second push assembly 300 drives the support foot 900 to move back and forth through the support foot placement seat 600.

[0037] According to some embodiments of this application, refer to Figures 1 to 4 The system also includes a base plate 700, with multiple slide rails 710 on top of the base plate 700 and multiple slide grooves 620 below the support foot holder 600. The slide rails 710 and slide grooves 620 are slidably connected in a one-to-one correspondence. Preferably, there are two slide rails 710 and two slide grooves 620, with each pair corresponding to one other. This one-to-one correspondence between the slide rails 710 and slide grooves 620 allows for limiting the movement of the support foot holder 600 in the front-back direction, enabling more precise and stable movement.

[0038] According to some embodiments of this application, refer to Figure 3 and Figure 4 The second pushing assembly 300 includes a second cylinder 310 and a second pushing block 320. The second pushing block 320 is connected to the output end of the second cylinder 310 and is matched with the support foot placement seat 600. The second cylinder 310 can drive the second pushing block 320 to move in the front-back direction. The second pushing block 320 can drive the support foot placement seat 600 to move in the front-back direction, thereby driving the support foot 900 to move towards the front of the connecting frame 800 through the support foot placement seat 600. Finally, the support foot 900 is pushed to the front of the connecting frame 800, and the support foot 900 and the connecting frame 800 are pressed together and connected.

[0039] As a preferred embodiment, the first cylinder 210, the second cylinder 310, the third cylinder 410, and the fourth cylinder 510 are all double-acting linear cylinders. The first cylinder 210, the second cylinder 310, the third cylinder 410, and the fourth cylinder 510 are each connected to different solenoid valves (not shown in the figure) for control, and these different solenoid valves are electrically connected to the control module (not shown in the figure).

[0040] Furthermore, referring to Figure 3 and Figure 4The piston rod extension and retraction direction of the second cylinder 310 is parallel to that of the piston rod of the first cylinder 210. Specifically, the second cylinder 310 can drive the support leg 900 to move backward toward the connecting frame 800 via the second push block 320 and the support leg placement seat 600; the first cylinder 210 can drive the connecting frame 800 to move forward toward the support leg 900 via the first push block 220. This mutual pushing and pressing of the support leg 900 and the connecting frame 800 achieves a tight connection, fixing the relative position between the support leg 900 and the connecting frame 800.

[0041] Specifically, refer to Figure 4 The support foot 900 has a U-shaped bar structure, and the front side of the connecting frame 800 is provided with a U-shaped groove. The support foot 900 with the U-shaped bar structure can be pushed into the U-shaped groove provided on the front side of the connecting frame 800, so as to limit the support foot 900 in the left, right and up and down directions.

[0042] Working principle: During processing, the connecting frame 800 to be welded is first placed on the connecting frame placement seat 100. Then, the first pushing assembly 200 applies a pushing force to the rear side of the connecting frame 800, pushing the connecting frame 800 to the rear side of the locking buckle 110. Then, the third pushing assembly 400 applies a pushing force to the left side of the connecting frame 800, pushing the connecting frame 800 to the designated position under the restriction of the limiting ring 440. Then, the fourth pushing assembly 500 applies a pushing force to the right side of the connecting frame 800. The third pushing assembly 400 and the fourth pushing assembly 500 push the connecting frame 800 from both the left and right sides, achieving... The connecting frame 800 is fixed in the left-right direction; then the support leg 900 to be welded is placed on the support leg placement seat 600, and then the second pushing component 300 drives the support leg placement seat 600 to move backward. During the backward movement, the support leg placement seat 600 drives the support leg 900 to be welded to move backward and pushes the support leg 900 to be welded to the front side of the connecting frame 800 to be welded, so that the support leg 900 to be welded and the connecting frame 800 to be welded are tightly fitted and fixedly connected; finally, the connection between the support leg 900 and the connecting frame 800 is welded by manual or mechanical welding equipment.
