[0043] To enable those skilled in the art to better understand the technical solution of the present invention, the present solution will be further described in detail below with reference to specific embodiments.

[0044] like Figures 1 to 7 As shown, this embodiment of the invention provides a modification fixture for prototype vehicle chassis components, comprising a support base 11, a first modification mechanism, and a second modification mechanism. The first modification mechanism includes two longitudinal guide rails 21 and four longitudinal and transverse adjustment components 31. The two longitudinal guide rails are disposed opposite to each other on the top surface of the support base, and two transverse and transverse adjustment components 31 are slidably disposed on each longitudinal guide rail 21. Each transverse and transverse adjustment component 31 includes a support platform 32, a transverse guide rail 37, and a workpiece modification platform 36. The support platform 32 is slidably connected to the longitudinal guide rails 21, and a longitudinal locking mechanism for locking it onto the longitudinal guide rails is provided on the support platform. A transverse guide rail 37 is disposed on the top surface of the support platform, and the extension direction of the transverse guide rail is perpendicular to the extension direction of the longitudinal guide rail; the workpiece modification table is slidably disposed on the transverse guide rail, and the workpiece modification table is provided with a transverse locking mechanism for locking it on the transverse guide rail; the second modification mechanism includes a support frame 41 and a vertical adjustment component 51, the support frame 41 is disposed on the top surface of the support base, and the vertical adjustment component is disposed on the support frame and located above the first modification mechanism; the vertical adjustment component has a moving part that can move up and down in the vertical direction and a locking part for locking the moving part.

[0045] The modification tooling for prototype vehicle chassis parts provided in this embodiment of the invention allows for convenient adjustment of the positions of the parts after they have been cut through the longitudinal guide rail 21, the transverse guide rail 31, and the vertical adjustment component 51. This facilitates the modification of the parts in the X, Y, and Z directions, making the modification of the parts more convenient and effectively improving the modification efficiency.

[0046] Furthermore, a longitudinal slider 33 is provided on the bottom surface of the support platform 32, and the longitudinal slider 33 slides in engagement with the longitudinal guide rail 21. Both ends of the longitudinal guide rail are provided with longitudinal limiting blocks 22 for engaging with the longitudinal slider. A transverse slider 361 is provided on the bottom surface of the workpiece modification platform, and the transverse slider slides in engagement with the transverse guide rail. The outer end of the transverse guide rail is provided with a first transverse limiting plate 371 for engaging with the transverse slider, and the inner end of the transverse guide rail is provided with a second transverse limiting plate 372 for engaging with the transverse slider. With this design, the longitudinal limiting blocks effectively limit the longitudinal slider, preventing it from detaching from the longitudinal guide rail; the first and second transverse limiting plates effectively limit the transverse slider, preventing it from detaching from the transverse guide rail.

[0047] Specifically, two longitudinal scales 12 are also provided on the top surface of the support base 11. The longitudinal scales are parallel to the longitudinal guide rails, and the two longitudinal scales are located on the outer side of the two longitudinal guide rails respectively. The first transverse limiting plate is provided with a longitudinal adjustment guide 35 opposite to the longitudinal scales, so that during modification, the size of the component in the longitudinal direction (X direction) can be accurately controlled by the cooperation of the longitudinal adjustment guide and the longitudinal scales.

[0048] Preferably, the longitudinal locking mechanism includes a longitudinal locking bolt 34, and the support platform is provided with a first threaded hole for engaging with the threaded section of the longitudinal locking bolt, the first threaded hole being opposite to the longitudinal guide rail. With this design, rotating the longitudinal locking bolt causes its lower end to press against the longitudinal guide rail, thus locking the support platform. It is understood that the longitudinal guide rail extends horizontally in the left-right direction.

[0049] Specifically, the transverse locking mechanism includes an L-shaped fixing plate 39 and a transverse locking bolt 391. The vertical plate of the L-shaped fixing plate is connected to one side of the workpiece modification table, and the horizontal plate of the L-shaped fixing plate is provided with a second threaded hole for engaging with the threaded section of the transverse locking bolt. The axis of the second threaded hole is perpendicular to the support table. Using this design, rotating the transverse locking bolt causes its lower end to press against the support table, thus locking the workpiece modification table and preventing further movement of both the workpiece modification table and the transverse slider.

[0050] Preferably, a horizontal scale 38 is provided on the support platform, the horizontal scale being parallel to the horizontal guide rail and located outside the horizontal guide rail; a horizontal adjustment guide 381 is provided on the workpiece modification platform, which is opposite to the horizontal scale, so that the adjustment dimension of the parts fixed on the workpiece modification platform in the horizontal direction (Y direction) can be precisely controlled during modification by cooperating with the horizontal scale.

[0051] Furthermore, the vertical adjustment assembly includes a support plate 54 and two transverse slide rails 61. The two transverse slide rails are parallel and opposite to each other on the top of the support frame. The left and right sides of the support plate are respectively mounted on the two transverse slide rails, which are parallel to the transverse guide rails. The moving component is a vertically arranged adjusting screw 52, ​​with a workpiece connecting seat 53 at its lower end. The support plate has a threaded hole for engaging with the adjusting screw. The locking component is a locking nut 55, which is mounted on the adjusting screw and located above the support plate. With this design, simply rotating the adjusting screw allows the workpiece connecting seat and the components fixed to it to move vertically up and down, facilitating easy adjustment of the components' vertical position and making modifications in the Z-axis more convenient. Simultaneously, when locking is required, simply rotating the locking nut presses it against the support plate to lock the adjusting screw.

[0052] Specifically, the left and right sides of the support plate are slidably connected to the transverse slide rail via the first slider 56. The support plate is threaded with a locking bolt 57. The lower end of the locking bolt 57 is used to abut against the transverse slide rail 61, thereby adjusting the position of the parts fixed on the workpiece connecting seat in the transverse direction (Y direction), so as to better meet the modification needs of different parts. At the same time, by pressing the lower end of the locking bolt 57 against the transverse slide rail, the support plate can be locked.

[0053] Furthermore, the support frame includes a rectangular frame 42 and four support columns 43. The upper ends of the four support columns are perpendicularly connected to the bottom surfaces of the four corners of the rectangular frame. The front and rear connecting rods of the rectangular frame are parallel to the longitudinal guide rails. Both the front and rear connecting rods are equipped with longitudinal slide rails, and the two ends of the transverse slide rails are slidably mounted on the two longitudinal slide rails via second sliders 64. This design simplifies the structure of the support frame. Furthermore, because the transverse slide rails can slide on the longitudinal slide rails, the position of the components fixed to the workpiece connecting seat in the longitudinal direction (X-axis) can be adjusted. This facilitates adjustments to the components fixed to the workpiece connecting seat in the X, Y, and Z directions, better meeting the modification needs of different components.

[0054] Specifically, a first scale 59 with the same extension direction is provided on the lower outer surface of the transverse slide rail, and a first adjustment guide 541 opposite to the first scale is provided on the first slider, so as to accurately control the adjustment dimension of the component fixed on the workpiece connecting seat in the Y direction; a second scale 73 with the same extension direction is provided on the lower outer surface of the longitudinal slide rail, and a second adjustment guide 63 opposite to the second scale is provided on the second slider, so as to accurately control the adjustment dimension of the component fixed on the workpiece connecting seat in the X direction.

[0055] Preferably, both ends of the transverse slide rail 61 are provided with a first limiting block 62 for engaging with the first slider, and both ends of the longitudinal slide rail 71 are provided with a second limiting block 72 for engaging with the second slider, thereby effectively limiting the first slider and the second slider.

[0056] Specifically, all the aforementioned adjustment guides are arrow-shaped, with the tips of each arrow pointing towards the respective scale. A slide rail support block 65 can be provided at the upper end of the second slider, and the front ends of both transverse slide rails are mounted on this support block, allowing the front ends of the two transverse slide rails to share a single second slider. The rear ends of the two transverse slide rails can also utilize this structure to achieve a sliding connection with the longitudinal slide rail. A locking component for locking the transverse slide rails onto the longitudinal slide rail can be provided on the slide rail support block. A toggle rod 551 is vertically mounted on the outer wall of the locking nut, facilitating rotation of the locking nut via the toggle rod. A buffer pad 552 can be provided on the top surface of the support plate. To securely lock the adjusting screw, a locking nut 58 can also be provided on the adjusting screw. This locking nut is located between the workpiece connecting seat and the support plate. When locking is required, the locking nut and the locking nut press against the top and bottom surfaces of the support plate respectively, thus locking the adjusting screw.

[0057] like Figure 8 and Figure 9 As shown in a specific embodiment, the general modification steps for the "I"-shaped component using the modified tooling of the present invention are as follows:

[0058] S1: Fix the two crossbeams 81 of the "I"-shaped component to the four workpiece modification tables respectively, so that the workpiece connecting seat is fixedly connected to the longitudinal beam 82 of the "I"-shaped component. The connection method here can be spot welding. Then, according to the actual modification requirements, the "I"-shaped component is cut into component one 91, component two 92, component three 93, component four 94, and component five 95. Among them, component one, component two, component three, and component four are fixed to the four workpiece modification tables respectively, and component five is fixed to the workpiece connecting seat.

[0059] S2: According to the actual modification requirements, each horizontal slider slides on each horizontal guide rail. After each workpiece modification table moves into place with each horizontal slider, the horizontal locking bolts can be used to lock each workpiece modification table. At this time, the dimensional modification requirements of part 1 91, part 2 92, part 3 93, and part 4 94 in the Y direction are completed.

[0060] S3: According to the actual modification requirements, each longitudinal slider slides on each longitudinal guide rail. After each workpiece modification table and support table moves into place with each longitudinal slider, the longitudinal locking bolts can be used to lock each support table so that the workpiece modification table no longer moves. At this time, the dimensional modification requirements of part 1 91, part 2 92, part 3 93, and part 4 94 in the X direction are completed.

[0061] S4: According to the actual modification requirements, rotate the adjusting screw to make the workpiece connecting seat and the component five fixed on it move up and down in the vertical direction. After the workpiece connecting seat moves to the required position, the adjusting screw can be locked to complete the dimensional modification requirements of component five 95 in the Z direction. Then, according to the modification requirements, the spatial position of the workpiece connecting seat and the component five fixed on it can be adjusted in the X and Y directions through the horizontal and vertical slide rails. After the adjustment is in place, it can be locked.

[0062] The modification fixture of this invention not only solves the problem of achieving X and Y-axis translation during the modification of parts, but also simultaneously achieves synchronous Z-axis translation during X and Y-axis translation. This operation method not only solves the modification needs of parts with different directions, sizes, and positions, but also reduces assembly steps and greatly improves the accuracy of synchronous modification, enabling the modification of automotive parts with different shapes and sizes. At the same time, multiple adjustment components cooperate with each other to simultaneously meet the modification needs of different spatial positions. The workpiece to be modified is constrained on the workpiece modification table, avoiding deformation and misalignment of the workpiece due to cutting, welding, and displacement during the modification process. Furthermore, multiple adjustment components can be operated simultaneously, saving a lot of modification operation time, thereby shortening the modification cycle and saving manpower and material resources.

[0063] The above are merely preferred embodiments of the present invention. It should be noted that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. Moreover, after reading the contents of the present invention, those skilled in the art can make various modifications or alterations to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.
