Description

Technical Field

[0001] This utility model relates to the field of welding tooling technology, and more specifically, to welding tooling for motorcycle engine mounting brackets. Background Technology

[0002] A welding fixture for motorcycle engine mounting brackets is a specialized process equipment used for precise positioning and reliable fixing of engine mounting brackets and related components during the welding process. For example, the welding fixture proposed in publication number "CN208772826U" includes a worktable with two symmetrically arranged first baffles. A vertically arranged fixing frame is fixed to the worktable near each of the first baffles. A second baffle, perpendicular to the first baffle, is located at the upper end of one side of each fixing frame. A limit rod is rotatably connected to the end of the second baffle away from the fixing frame. A support assembly for supporting the limit rod is located at the end of the fixing frame away from the second baffle. The fixing frame, second baffles, limit rod, and support assembly form a closed workpiece placement area. First fixing components for fixing the vertical frame are located at both the upper and lower ends of the fixing frame.

[0003] However, in the above technical solution, since the position and angle of each positioning component in the welding fixture are not adjustable, it lacks an adaptive adjustment function suitable for workpieces with complex spatial structures such as motorcycle engine mounting brackets. As a result, when welding such workpieces, it is easy to cause inaccurate positioning, which affects the welding accuracy. Utility Model Content

[0004] The main purpose of this utility model is to provide a welding fixture for motorcycle engine mounting brackets, which can effectively solve the problem that the positions and angles of the positioning components in the welding fixtures in the background art are not adjustable. This results in the lack of adaptive adjustment function for workpieces with complex spatial structures such as motorcycle engine mounting brackets, which makes it easy to produce inaccurate positioning when welding such workpieces, thus affecting the welding accuracy.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A welding fixture for a motorcycle engine mounting bracket includes a base. The upper surface of the base has two first arc-shaped grooves and a second arc-shaped groove. A first arc-shaped block is slidably disposed in each of the two first arc-shaped grooves, and two second arc-shaped blocks are slidably disposed in each of the two second arc-shaped grooves. A first movable plate is fixedly mounted on the upper surface of each first arc-shaped block, and a second movable plate is fixedly mounted on the upper surface of each second arc-shaped block. A first base plate is disposed at the upper end of each first movable plate, and a second base plate is disposed at the upper end of each second movable plate. A first positioning component is disposed on the upper surface of each first base plate, and a second positioning component is disposed on the upper surface of each second base plate. An adjustment component for adjusting the angle is disposed on the upper surface of each first movable plate and each second movable plate.

[0007] Each of the first and second movable plates has several tightening bolts threaded through its upper surface.

[0008] Preferably, the adjustment assembly includes a mounting bracket, each of which is fixedly mounted on the upper surface of a corresponding first or second movable plate. A vertical shaft is rotatably mounted on the bottom of each mounting bracket, and the upper end of each vertical shaft is fixedly connected to a corresponding first or second base plate.

[0009] Preferably, each vertical shaft is fitted with a worm gear, and a worm is rotatably mounted between the two sides of the inner wall of each mounting bracket, with each worm meshing with a corresponding worm gear.

[0010] One end of the worm gear passes through the corresponding mounting bracket and is fixedly mounted with a rotating wheel.

[0011] Preferably, an arc-shaped rod is fixedly installed between the two sides of the inner wall of each of the first and second arc-shaped grooves, and each of the first and second arc-shaped blocks is slidably disposed on one side of the corresponding arc-shaped rod.

[0012] Preferably, the first positioning component includes a frame, which is fixedly installed on the upper surface of a corresponding first base plate. An upper baffle and a lower baffle are fixedly installed on one side of the frame. A bracket is fixedly installed on the upper surface of the upper baffle. A gate is rotatably installed between the two sides of the inner wall of the bracket. A limit frame is fixedly installed on one side of the frame.

[0013] A base frame is fixedly installed on the other side of the frame, and a first cylinder is fixedly installed on the upper surface of each of the two base frames. A first top plate is fixedly installed on the output end of each of the two first cylinders.

[0014] Preferably, the second positioning component includes a second cylinder, which is fixedly mounted on the upper surface of the corresponding second base plate, and a second push plate is fixedly mounted on the output end of the second cylinder.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) The operator first loosens each tightening bolt to release the lock on the first arc block and the second arc block. Then, according to the dimensions and shape requirements of the drawing of the motorcycle engine mounting bracket to be welded, the operator manually pushes each first moving plate and the second moving plate so that the first arc block and the second arc block at the bottom slide along the corresponding first arc groove and the second arc groove. This allows for the initial adjustment of the circumferential position of each first positioning component and the second positioning component on the base. By rotating the rotating wheel, the worm gear is rotated, which in turn drives the worm wheel meshing with it to rotate. This allows the vertical shaft to rotate the first base plate or the second base plate above and the entire positioning component on it. By setting the first moving plate and the second moving plate that can slide along the first arc groove and the second arc groove, and by using the angle adjustment mechanism composed of the worm wheel, the worm and the rotating wheel, the spatial position and installation angle of each first positioning component and the second positioning component can be flexibly adjusted over a wide range, effectively adapting to the welding requirements of different models of motorcycle engine mounting brackets.

[0025] like Figures 1-6 As shown, the welding fixture for a motorcycle engine mounting bracket includes a base 1. The upper surface of the base 1 has two first arc-shaped grooves 2 and a second arc-shaped groove 3. A first arc-shaped block 201 is slidably disposed within each of the two first arc-shaped grooves 2, and two second arc-shaped blocks 4 are slidably disposed within each of the two second arc-shaped grooves 3. A first movable plate 301 is fixedly mounted on the upper surface of each first arc-shaped block 201, and a second movable plate 401 is fixedly mounted on the upper surface of each second arc-shaped block 4. A first base plate 302 is disposed at the upper end of each first movable plate 301, and a second base plate 402 is disposed at the upper end of each second movable plate 401. A first positioning component 5 is disposed on the upper surface of each first base plate 302, and a second positioning component 6 is disposed on the upper surface of each second base plate 402. An adjustment component 7 for adjusting the angle is disposed on the upper surface of each first movable plate 301 and each second movable plate 401.

[0026] Each of the first moving plate 301 and the second moving plate 401 has several tightening bolts 8 threaded through its upper surface.

[0027] The adjustment assembly 7 includes a mounting bracket 701. Each mounting bracket 701 is fixedly mounted on the upper surface of the corresponding first movable plate 301 or second movable plate 401. A vertical shaft 702 is rotatably mounted on the bottom of each mounting bracket 701. The upper end of each vertical shaft 702 is fixedly connected to the corresponding first base plate 302 or second base plate 402.

[0028] Each vertical shaft 702 is fitted with a worm gear 703, and a worm 704 is rotatably mounted between the two sides of the inner wall of each mounting bracket 701. Each worm 704 meshes with the corresponding worm gear 703.

[0029] One end of the worm gear 704 passes through the corresponding mounting bracket 701 and is fixedly mounted with a rotating wheel 705.

[0030] The first positioning component 5 includes a frame 501, which is fixedly installed on the upper surface of the corresponding first base plate 302. An upper baffle 502 and a lower baffle 503 are fixedly installed on one side of the frame 501. A bracket 504 is fixedly installed on the upper surface of the upper baffle 502. A gate 505 is rotatably installed between the two sides of the inner wall of the bracket 504. A limit frame 506 is fixedly installed on one side of the frame 501.

[0031] A base frame 507 is fixedly installed on the other side of the frame 501. A first cylinder 508 is fixedly installed on the upper surface of both base frames 507, and a first top plate 509 is fixedly installed on the output end of both first cylinders 508.

[0032] The second positioning component 6 includes a second cylinder 601, which is fixedly installed on the upper surface of the corresponding second base plate 402, and a second push plate 602 is fixedly installed at the output end of the second cylinder 601.

[0033] The operator first loosens the tightening bolts 8 to release the locks on the first arc-shaped block 201 and the second arc-shaped block 4. Then, according to the dimensions and shape requirements of the drawing of the motorcycle engine mounting bracket to be welded, the operator manually pushes the first moving plate 301 and the second moving plate 401, causing the bottom first arc-shaped block 201 and the second arc-shaped block 4 to slide along the corresponding first arc-shaped groove 2 and the second arc-shaped groove 3, thereby initially adjusting the circumferential position of the first positioning components 5 and the second positioning components 6 on the base 1. By rotating the rotating wheel 705, the worm gear 704 is rotated, driving the meshing worm wheel 703 to rotate, so that the vertical shaft 702 drives the upper first base plate 302 or the second base plate 402 and the entire positioning components on it to adjust the rotation angle. After the adjustment is completed, the tightening bolts 8 are tightened again to firmly fix the first arc-shaped block 201 and the second arc-shaped block 4 in the current arc-shaped groove position. The motorcycle engine mounting bracket workpiece is then placed on the adjusted positioning components, so that the workpiece reference surface is aligned with the first positioning components. The upper baffle 502 and lower baffle 503 in component 5 are brought together. Then, the gate 505 is manually rotated so that it rotates around the bracket 504 and engages above the workpiece, restricting the vertical movement of the workpiece. Then, the first cylinder 508 is activated to push the first top plate 509 to press the workpiece onto the upper baffle 502 and lower baffle 503. At the same time, the second cylinder 601 on the second positioning component 6 is activated to push the second push plate 602 to assist in pressing the workpiece. After welding is completed, the cylinders are controlled to retract and the clamping is released. The gate 505 is manually opened and rotated to the open position. Then, the workpiece is removed from the fixture. By setting the first moving plate 301 and the second moving plate 401 that can slide along the first arc groove 2 and the second arc groove 3, and by using the angle adjustment mechanism composed of the worm gear 703, the worm 704 and the rotating wheel 705, the spatial position and installation angle of each first positioning component 5 and the second positioning component 6 can be flexibly adjusted over a wide range, effectively adapting to the welding requirements of different models of motorcycle engine mounting brackets.

[0034] In another embodiment of this utility model, an arc-shaped rod 9 is fixedly installed between the two sides of the inner wall of each first arc-shaped groove 2 and second arc-shaped groove 3, and each first arc-shaped block 201 and second arc-shaped block 4 are slidably disposed on one side of the corresponding arc-shaped rod 9.

[0035] The arc-shaped rod 9 provides precise guidance and limits for the movement trajectory of the first arc-shaped block 201 and the second arc-shaped block 4, ensuring that the moving plate slides smoothly along the predetermined arc-shaped trajectory and preventing deviation or even disengagement from the groove during the adjustment process, thereby improving the accuracy and reliability of the position adjustment.

[0036] The working principle of this motorcycle engine mounting bracket welding fixture:

[0037] During operation, the operator first loosens the tightening bolts 8 to release the locks on the first arc-shaped block 201 and the second arc-shaped block 4. Then, according to the dimensions and shape requirements of the drawing of the motorcycle engine mounting bracket to be welded, the operator manually pushes the first moving plate 301 and the second moving plate 401, causing the bottom first arc-shaped block 201 and the second arc-shaped block 4 to slide along the corresponding first arc-shaped groove 2 and the second arc-shaped groove 3, thereby initially adjusting the circumferential position of the first positioning components 5 and the second positioning components 6 on the base 1. By rotating the rotating wheel 705, the worm gear 704 is rotated, driving the meshing worm wheel 703 to rotate, so that the vertical shaft 702 drives the upper first base plate 302 or the second base plate 402 and the entire positioning components on it to adjust the rotation angle. After the adjustment is completed, the tightening bolts 8 are tightened again to firmly fix the first arc-shaped block 201 and the second arc-shaped block 4 in the current arc-shaped groove position. The motorcycle engine mounting bracket workpiece is placed on the adjusted positioning components, so that the workpiece reference surface is aligned with the first... The upper baffle 502 and lower baffle 503 in the positioning assembly 5 are brought together. Then, the gate 505 is manually rotated so that it rotates around the bracket 504 and engages above the workpiece, restricting the vertical movement of the workpiece. Then, the first cylinder 508 is activated to push the first top plate 509 to press the workpiece onto the upper baffle 502 and lower baffle 503. At the same time, the second cylinder 601 on the second positioning assembly 6 is activated to push the second push plate 602 to assist in pressing the workpiece. After welding is completed, the cylinders are controlled to retract, the clamping is released, and the gate 505 is manually opened and rotated to the open position. Then, the workpiece is removed from the fixture. By setting the first moving plate 301 and the second moving plate 401 that can slide along the first arc groove 2 and the second arc groove 3, and by using the angle adjustment mechanism composed of the worm gear 703, the worm 704 and the rotating wheel 705, the spatial position and installation angle of each first positioning assembly 5 and the second positioning assembly 6 can be flexibly adjusted over a wide range, effectively adapting to the welding requirements of different models of motorcycle engine mounting brackets.

For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
