[0070] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes rather than for limiting the present invention.

[0071] In the description of the present application, it should be understood that in the embodiments shown in the drawings, the indications of directions or positional relationships (such as up, down, left, right, front and back, etc.) are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, the indications of these directions also change accordingly.

[0072] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0073] See also Figure 1 and Figure 2 As shown, the manufacturing tool 10 of the semitrailer frame 20 according to the embodiment of the utility model includes a frame 100 and a plurality of longitudinal beam positioning assemblies 200. The plurality of longitudinal beam positioning assemblies 200 are arranged on the frame 100 at intervals along the length direction of the frame 100. Each longitudinal beam positioning assembly 200 includes a base 210, and each base 210 is slidably connected to the frame 100 along the length direction of the frame 100, and the length direction of each base 210 is perpendicular to the length direction of the frame 100.

[0074] For ease of description, it is now stipulated that the frame 20 of the semi-trailer is taken as a reference, its length direction is X direction, its width direction is Y direction, and its height direction is Z direction. In the length direction of the frame 20, the end of the frame 20 used for connecting with the front of the vehicle is the front end, and the end opposite to the front end is the rear end.

[0075] like Figure 1 As shown, the frame 100 is generally a rectangular frame structure, which includes a plurality of beams arranged in a crisscross pattern. It can be understood that the length direction, width direction and height direction of the frame 100 are respectively parallel to the aforementioned X direction, Y direction and Z direction.

[0076] See also Figure 3 In one embodiment, the frame 100 includes two main longitudinal beams 110 arranged in parallel and spaced apart, and both ends of each base 210 are slidably connected to the two main longitudinal beams 110. Therefore, the base 210 can be slidably arranged on the main longitudinal beams 110, so that each longitudinal beam positioning assembly 200 can move on the frame 100 along the X direction, thereby realizing the positioning of the frame 20 of different vehicle models in the X direction.

[0077] The base 210 and the main longitudinal beam 110 may be slidably connected in a manner that each main longitudinal beam 110 may be formed with a first sliding groove 111 extending and continuous along the length direction of the frame 100. Figure 4 As shown, optionally, the main longitudinal beam 110 includes two U-shaped channel steels 114 and a spacer plate 115 connected between the two U-shaped channel steels 114. The openings of the two U-shaped channel steels 114 are arranged opposite to each other and form a spacer space 112 therebetween. The two U-shaped channel steels 114 are relatively spaced so that a gap 113 communicating with the spacer space 112 is formed on the upper surface of the main longitudinal beam 110, and the gap 113 and the spacer space 112 together constitute a first slide groove 111. The spacer plate 115 is located in the spacer space 112 and is used to keep the two U-shaped channel steels 114 spaced apart.

[0078] In this embodiment, the main longitudinal beam 110 is provided with two U-shaped channel steels 114 arranged opposite to each other, and a spacer plate 115 is used to keep the two U-shaped channel steels 114 spaced apart. The main longitudinal beam 110 makes full use of the appearance characteristics of the U-shaped channel steel 114 to form a T-shaped slide groove structure, which can match the T-shaped bolt to achieve sliding connection with the base 210. The main longitudinal beam 110 has low manufacturing cost and low processing precision requirements, which effectively reduces the cost of manufacturing the tooling 10.

[0079] Of course, in other embodiments, the main longitudinal beam 110 may also be formed by two I-beams arranged in parallel and at intervals, as long as the aforementioned continuous first slide groove 111 can be formed.

[0080] Alternatively, the main longitudinal beam 110 may also be replaced by other similar structures having a U-shaped groove, as long as the aforementioned continuous first sliding groove 111 can be formed.

[0081] See also Figure 1 and Figure 5 As shown, each base 210 may be provided with a first sliding portion 211 for sliding connection with the first sliding groove 111. In some embodiments, the first sliding portion 211 may be a sliding plate protruding from one side of the base 210, and a connecting groove is provided on the sliding plate. By using a T-bolt passing through the connecting groove and the first sliding groove 111, the sliding connection between the base 210 and the main longitudinal beam 110 can be achieved.

[0082] See also Figure 3 In one embodiment, the frame 100 further includes a plurality of cross beams 120 and positioning longitudinal beams 130 supported on the plurality of cross beams 120. The plurality of cross beams 120 are arranged between two main longitudinal beams 110 at intervals along the length direction of the frame 100. By providing a plurality of cross beams 120, the overall structural strength and stability of the frame 100 can be enhanced.

[0083] The positioning longitudinal beam 130 may be arranged parallel to the main longitudinal beam 110. The positioning longitudinal beam 130 is mainly used to realize the connection and setting of the beam positioning assembly 500 described later, and the specific method will be described in detail later.

[0084] like Figure 3 As shown, the positioning longitudinal beam 130 is supported and arranged on a plurality of cross beams 120, and can be reliably connected to each cross beam 120 by welding. After the positioning longitudinal beam 130 is connected and fixed to each cross beam 120, its upper surface can be flush with the upper surface of the main longitudinal beam 110.

[0085] In some embodiments, the stacking height of the positioning longitudinal beam 130 and the cross beam 120 along the Z direction can be designed to be just equal to the height of the main longitudinal beams 110 on both sides along the Z direction, so that the upper surface of the positioning longitudinal beam 130 can be flush with the upper surface of the main longitudinal beam 110. In this way, the upper surface of the frame 100 can be flat, and the positioning accuracy of each longitudinal beam positioning assembly 200 and each cross beam positioning assembly 500 can be better guaranteed.

[0086] See also Figure 3 In some embodiments, a foot 140 is provided at the bottom of the frame 100. The foot 140 may be a height-adjustable foot. The height-adjustable foot 140 may be connected to the bottom of the main longitudinal beam 110.

[0087] Alternatively, the foot 140 can be a fixed height foot. The fixed height foot 140 can be connected to the bottom of the beam 120.

[0088] See also Figure 5 In some embodiments, a foot is provided at the bottom of the base 210. The foot may be a height-adjustable foot.

[0089] like Figure 1 As shown, a plurality of longitudinal beam positioning assemblies 200 can be arranged on the frame 100 at intervals along the X direction. The base 210 of each longitudinal beam positioning assembly 200 is slidably connected to the frame 100 along the X direction. Since each base 210 is slidably arranged on the main longitudinal beam 110, each longitudinal beam positioning assembly 200 can move on the frame 100 along the X direction, thereby realizing the positioning of the frame 20 of different vehicle models in the X direction.

[0090] In the present application, the plurality of longitudinal beam positioning assemblies 200 are mainly used to support and position the beams extending along the X direction of the frame 20, that is, Figure 2 The main beam 201 and the side beam 202 of the frame 20 are shown in FIG.

[0091] See also Figure 2 and Figure 7As shown, in one embodiment, among the plurality of longitudinal beam positioning assemblies 200, at least one longitudinal beam positioning assembly 200 includes a beam positioning portion 300, and the beam positioning portion 300 is slidably connected to the base 210 along the length direction of the base 210, so as to position the beam 201 of the frame 20. The beam positioning portion 300 is slidably arranged on the base 210, so that the beam positioning portion 300 can move on the base 210 along the Y direction, thereby realizing the positioning of the beam 201 of the frame 20 of different vehicle models in the Y direction.

[0092] The beam positioning portion 300 and the base 210 may be slidably connected in a manner that: each base 210 is formed with a third sliding groove 212 extending and continuous along the length direction of the base 210. Figure 5 and Figure 6 As shown, the third slide groove 212 formed on each base 210 can be similar to the structure of the first slide groove 111 formed on the main longitudinal beam 110, that is, the base 210 includes two U-shaped channel steels with openings arranged opposite to each other, and a spacer connected between the two U-shaped channel steels. Thus, the third slide groove 212 for sliding connection with the beam positioning part 300 can be formed on the upper surface of the base 210.

[0093] like Figure 5 As shown, the number of the third slide grooves 212 formed on the base 210 may be two. That is, two sets of structures including two U-shaped channel steels with openings facing each other and a partition plate connected between the two U-shaped channel steels may be provided on the base 210 to form two third slide grooves 212 .

[0094] like Figure 5 and Figure 6 As shown, in order to facilitate the arrangement of two groups of structures including two U-shaped channel steels with openings facing each other and a spacer plate connected between the two U-shaped channel steels, the base 210 further includes a bottom plate 213. The two groups of two U-shaped channel steels with openings facing each other are fixed in parallel on the bottom plate 231, and the two third slide grooves 212 are parallel to each other. Therefore, the base 210 can be more stably connected to the beam positioning portion 300.

[0095] In addition, the cross-sectional dimension of the U-shaped channel steel used in the base 210 may be smaller than the cross-sectional dimension of the U-shaped channel steel 114 used in the main longitudinal beam 110 .

[0096] See also Fig. 9As shown, in one embodiment, a positioning groove 310 for clamping the beam 201 of the frame 20 is formed on the beam positioning part 300, and the opening degree of the positioning groove 310 along the length direction of the base 210 is adjustable. By designing that the opening degree of the positioning groove 310 in the Y direction is adjustable, the beam positioning part 300 can be adaptively adjusted in the Y direction according to the size of the beam 201 of the frame 20 of different models, so as to realize the clamping and positioning of the beam 201 of the frame 20 of different models. This is conducive to expanding the use scope of the manufacturing tool 10 and improving its versatility.

[0097] See also Fig.10 In one embodiment, the beam positioning portion 300 includes a first plate body 320 and a second plate body 330 that are spaced apart from each other, and a mounting plate 340 and a connecting plate 350 that are connected between the first plate body 320 and the second plate body 330. The first plate body 320 and the second plate body 330 are both notched upward to form the aforementioned positioning groove 310. The mounting plate 340 and the connecting plate 350 are spaced apart and arranged on both sides of the positioning groove 310 along the Y direction.

[0098] The mounting plate 340 is provided with a clamping plate 360 ​​and a power member 370 for driving the clamping plate 360 ​​to move along the Y direction. The clamping plate 360 ​​can move away from or close to the connecting plate 350 along the Y direction, so that the opening degree of the positioning groove 310 along the Y direction can be adjusted as needed. The power member 370 can be a cylinder or an electric cylinder, etc.

[0099] It should be noted that, in some other embodiments, the connecting plate 350 may be omitted from the beam positioning portion 300 , as long as the connection between the various plates of the beam positioning portion 300 is ensured to be stable.

[0100] Alternatively, the functions of the mounting plate 340 and the connecting plate 350 may be interchanged, that is, the pressing plate 360 ​​and the power member 370 may be disposed on the connecting plate 350 .

[0101] like Fig. 9 and Fig.10 As shown, the beam positioning part 300 is provided with a first sliding seat 380 for sliding connection with the third sliding groove 212. In some embodiments, the first sliding seat 380 can be a slider connected to the bottom of the first plate body 320 and the second plate body 330, and the slider is provided with a through hole for inserting a T-bolt. By passing the T-bolt through the through hole and the third sliding groove 212, the beam positioning part 300 can be slidably connected with the base 210.

[0102] See also Figure 2As shown, in one embodiment, among the plurality of longitudinal beam positioning assemblies 200, at least one longitudinal beam positioning assembly 200 includes a side beam positioning portion 400, which is slidably connected to the base 210 along the length direction of the base 210, and is used to position the side beam 202 of the frame 20. The side beam positioning portion 400 is slidably arranged on the base 210, so that the side beam positioning portion 400 can move on the base 210 along the Y direction, thereby realizing the positioning of the side beam 202 of the frame 20 of different vehicle models in the Y direction.

[0103] In order to achieve the sliding connection between the side beam positioning portion 400 and the base 210, each base 210 is formed with a third sliding groove 212 extending and continuous along the length direction of the base 210. Figure 5 and Figure 6 As shown, the third slide groove 212 formed on each base 210 can be similar to the structure of the first slide groove 111 formed on the main longitudinal beam 110, that is, the base 210 includes two U-shaped channel steels with openings arranged opposite to each other, and a spacer connected between the two U-shaped channel steels. Thus, the third slide groove 212 for sliding connection with the side beam positioning portion 400 can be formed on the upper surface of the base 210.

[0104] The number of the third chute 212 formed on the base 210 may be two, that is, two sets of structures including two U-shaped channel steels with openings facing each other and a partition plate connected between the two U-shaped channel steels may be provided on the base 210 to form two third chute 212 .

[0105] like Figure 6 As shown, in order to facilitate the arrangement of two groups of structures including two U-shaped channel steels with openings facing each other and a spacer plate connected between the two U-shaped channel steels, the base 210 further includes a bottom plate 213, on which the two groups of two U-shaped channel steels with openings facing each other are fixed in parallel, and the two third slide grooves 212 are parallel to each other. Therefore, the base 210 can be more stably connected to the side beam positioning portion 400.

[0106] In addition, the cross-sectional dimension of the U-shaped channel steel used in the base 210 may be smaller than the cross-sectional dimension of the U-shaped channel steel 114 used in the main longitudinal beam 110 .

[0107] See also Fig.11 As shown, in one embodiment, the side beam positioning portion 400 includes a first positioning portion 410 and a second positioning portion 420. The first positioning portion 410 and the second positioning portion 420 are respectively slidably disposed at both ends of the base 210 and can be located on both sides of the width direction of the frame 20. The first positioning portion 410 and the second positioning portion 420 can act on the side beam 202 of the frame 20 from both sides of the frame 20 to position the side beam 202 of the frame 20.

[0108] In the present application, the first positioning portion 410 can position the support side beam 202 in the Y direction and the Z direction respectively. Fig.11 and Fig.12 As shown, in one embodiment, the first positioning portion 410 includes a support seat 411, a first positioning pile 412 and a first tightening assembly 413. The support seat 411 is slidably connected to the base 210 along the Y direction, and the first positioning pile 412 is disposed on the support seat 411 and protrudes upward from the support seat 411. The first tightening assembly 413 is disposed above the support seat 411 and is slidably connected to the first positioning pile 412 along the Z direction. The first tightening assembly 413 is used to tighten the side beam 202 along the Y direction, thereby realizing the positioning of the side beam 202.

[0109] Further, the first pressing assembly 413 may include a first pressing block 415 and a first driving member 414, wherein the first driving member 414 is drivingly connected to the first pressing block 415 to drive the first pressing block 415 to move along the Y direction. The first driving member 414 may be a cylinder. In other embodiments, the first driving member 414 may also be an electric cylinder or a screw nut structure, etc.

[0110] In this embodiment, the support seat 411 is mainly used to support the side beam 202 along the Z direction. The first positioning pile 412 is mainly used to adjust the position of the first tightening assembly 413 along the Z direction, so that the first tightening block 415 can move up and down to tighten the side beam 202 of the frame 20 of different vehicle models. The first tightening block 415 can move along the Y direction under the drive of the first driving member 414 and then abut against the side beam 202, thereby realizing the tightening positioning of the side beam 202.

[0111] There are many ways for the first positioning pile 412 to adjust the position of the first pressing component 413 along the Z direction, which is not specifically limited in this application. For example, the first positioning pile 412 is provided with a plurality of first positioning holes 416 arranged at intervals along the Z direction, and the cylinder seat of the first pressing component 413 may be provided with through holes corresponding to the first positioning holes 416. By using positioning pins inserted into the first positioning holes 416 and the through holes, the first pressing component 413 can be fixed at different heights on the first positioning pile 412 as needed.

[0112] Of course, the first positioning pile 412 may also be provided with a track for slidingly mounting a cylinder seat of the first tightening assembly 413 , and this application does not make any specific limitation to this.

[0113] In one embodiment, the first positioning pile 412 is slidably connected to the support seat 411 along the Y direction. Therefore, when the first driving member 414 drives the first tightening block 415 to move within a limited stroke, the side beam 202 of the vehicle frame 20 can be better positioned in the Y direction by moving the first positioning pile 412 in the Y direction, thereby broadening the applicability of the manufacturing tool 10.

[0114] Of course, in other embodiments, the first positioning pile 412 may also be relatively fixedly connected to the support seat 411 in the Y direction. For example, the first positioning pile 412 may be detachably fixed to the support seat 411 by fasteners such as screws.

[0115] In the present application, the second positioning portion 420 can position the support side beam 202 in the Y direction and the Z direction respectively. Fig.11 and Fig.13 As shown, in one embodiment, the second positioning portion 420 includes a support block 421, a second positioning pile 422, and a second tightening assembly 423. The support block 421 is slidably connected to the base 210 along the Y direction. The second positioning pile 422 is slidably connected to the base 210 along the Y direction and is located on one side of the support block 421. The second tightening assembly 423 is slidably connected to the second positioning pile 422 along the Z direction, and the second tightening assembly 423 is used to tighten the side beam 202 along the Y direction, thereby realizing the positioning of the side beam 202.

[0116] Further, the second pressing assembly 423 may include a second pressing block 425 and a second driving member 424, and the second driving member 424 is drivingly connected to the second pressing block 425 to drive the second pressing block 425 to move along the Y direction. The second driving member 424 may be a screw nut structure. In other embodiments, the second driving member 424 may also be a cylinder or an electric cylinder, etc.

[0117] In this embodiment, the support block 421 is mainly used to support the side beam 202 along the Z direction. The second positioning pile 422 is mainly used to adjust the position of the second tightening assembly 423 along the Z direction, so that the second tightening block 425 can move up and down to tighten the side beam 202 of the frame 20 of different vehicle models. The second tightening block 425 can move along the Y direction driven by the second driving member 424 and then abut against the side beam 202, thereby realizing the tightening positioning of the side beam 202.

[0118] There are many ways for the second positioning pile 422 to adjust the position of the second tightening assembly 423 along the Z direction, and this application does not specifically limit this. For example, the second positioning pile 422 is provided with a long strip hole along the Z direction for the screw rod of the second driving member 424 to pass through, and the nut on the screw rod can move on the second positioning pile 422 along the Z direction. The second positioning pile 422 can be provided with a plurality of second positioning holes 426 arranged at intervals along the Z direction. By using a positioning pin inserted into the second positioning hole 426 and the positioning pin abutting against the bottom of the nut, the second tightening assembly 423 can be fixed at different heights on the second positioning pile 422 as needed.

[0119] See also Fig.11In one embodiment, the second positioning portion 420 further includes a quick release pressing block 427, which is detachably connected to the second pressing block 425 and is located above the support block 421. The quick release pressing block 427 can press the side beam 202 downward, and the quick release pressing block 427 cooperates with the support block 421 below it to better press and position the side beam 202 in the Z direction.

[0120] In order to achieve the sliding connection between the side beam positioning portion 400 and the base 210, the side beam positioning portion 400 is provided with a second sliding seat 430 for sliding connection with the third slide groove 212. It can be understood that in the embodiment of the present application, the side beam positioning portion 400 includes a first positioning portion 410 and a second positioning portion 420. The first positioning portion 410 and the second positioning portion 420 are both provided with the aforementioned second sliding seat 430 to respectively achieve the sliding connection with the base 210.

[0121] like Fig.12 As shown, in some embodiments, the second sliding seat 430 can be a plate on the bottom side of the support seat 411, and the plate on the bottom side is provided with a connection hole 431 for passing a T-bolt. By passing the T-bolt through the connection hole 431 and the third slide groove 212, the first positioning portion 410 can be slidably connected to the base 210.

[0122] like Fig.13 As shown, in some embodiments, the second sliding seat 430 can be a plate connected to the bottom of the second positioning pile 422, and the plate is provided with a connection hole 431 for passing a T-bolt. By passing the T-bolt through the connection hole 431 and the third slide groove 212, the second positioning portion 420 can be slidably connected to the base 210.

[0123] In this application, if Figure 1 As shown, in order to ensure the positioning accuracy of the frame 20 and reduce the limitation of the operating space, the longitudinal beam positioning assembly 200 provided with the main beam positioning part 300 and the longitudinal beam positioning assembly 200 provided with the side beam positioning part 400 can be arranged alternately along the length direction of the frame 100.

[0124] like Figure 7 As shown, in a possible embodiment, one of the plurality of longitudinal beam positioning assemblies 200 is disposed at the rear end of the frame 100, and its base 210 can abut against the rear end of the frame 20 to stop and position the frame 20 along the length direction of the frame 100. By disposing one of the longitudinal beam positioning assemblies 200 at the rear end of the frame 100 so that its base 210 can abut against the rear end of the frame 20, the positioning of the frames 20 of different vehicle models in the X direction can be achieved.

[0125] In this embodiment, Figure 7As shown, the base 210 connected to the rear end of the frame 100 can be abutted against the rear end of the beam 201 of the frame 20, so that the position of the frame 20 relative to the frame 100 in the X direction can be fixed.

[0126] In other embodiments, the base 210 connected to the rear end of the frame 100 may also abut against the rear end of the side beam 202 of the frame 20 to achieve the positioning of the frame 20 in the X direction.

[0127] Alternatively, the base 210 connected to the rear end of the frame 100 may also abut against the rear end cross beam of the frame 20 to achieve the positioning of the frame 20 in the X direction.

[0128] See also Figure 2 As shown, in a possible embodiment, the manufacturing tool 10 also includes a plurality of beam positioning assemblies 500, and the plurality of beam positioning assemblies 500 are arranged on the positioning longitudinal beam 130 at intervals along the length direction of the frame 100, and each beam positioning assembly 500 is slidably connected to the positioning longitudinal beam 130 along the length direction of the frame 100.

[0129] In the present application, the crossbeam positioning assembly 500 is mainly used to support and position the beam extending along the Y direction of the frame 20, that is, Figure 2 By making each beam positioning assembly 500 slidably disposed on the positioning longitudinal beam 130, each beam positioning assembly 500 can move on the positioning longitudinal beam 130 along the X direction, thereby realizing the positioning of the frame beam 203 of different vehicle models in the X direction.

[0130] like Figure 8 As shown, in some embodiments, the beam positioning assembly 500 includes a positioning column 510 and a support plate 520 connected to one side of the positioning column 510. The support plate 520 and the positioning column 510 are perpendicular to each other, and an L-shaped step structure can be formed between the two. The support plate 520 can support and position the frame beam 203 along the Z direction, and the positioning column 510 can position the frame beam 203 along the X direction. Thereby, effective support and positioning of the frame beam 203 is achieved.

[0131] In the present application, the cross beam positioning assembly 500 and the positioning longitudinal beam 130 may be slidably connected in a manner that: the positioning longitudinal beam 130 may be formed with a second sliding groove 131 extending and continuous along the length direction of the frame 100. Figure 3 As shown, the structure of the positioning longitudinal beam 130 can be similar to that of the main longitudinal beam 110, that is, the positioning longitudinal beam 130 includes two U-shaped channel steels with openings arranged opposite to each other, and a spacer connected between the two U-shaped channel steels. Thus, a second sliding groove 131 for sliding connection with the cross beam positioning assembly 500 can be formed on the upper surface of the positioning longitudinal beam 130.

[0132] Optionally, the cross-sectional dimension of the U-shaped channel steel used in the positioning longitudinal beam 130 is smaller than the cross-sectional dimension of the U-shaped channel steel 114 used in the main longitudinal beam 110. Therefore, when the positioning longitudinal beam 130 is supported and arranged on each cross beam 120, it is advantageous to realize that the upper surface of the positioning longitudinal beam 130 is flush with the upper surface of the main longitudinal beam 110.

[0133] like Figure 8 As shown, the beam positioning assembly 500 may be provided with a second sliding portion 530 for slidingly connecting with the second slide groove 131. For example, the second sliding portion 530 is a plate body connected to the bottom of the positioning column 510, and the plate body is provided with a hole for inserting a T-bolt. By passing the T-bolt through the hole and the second slide groove 131, the beam positioning assembly 500 and the positioning longitudinal beam 130 can be slidably connected.

[0134] It can be seen from the above technical solution that the manufacturing tool 10 of the embodiment of the utility model has at least the following beneficial effects:

[0135] The manufacturing tool 10 of the embodiment of the utility model can meet the assembly and production requirements of the frames 20 of different models, expand the application scope of the manufacturing tool 10, and facilitate the flexible production of different types of semi-trailer frames 20.

[0136] The multiple longitudinal beam positioning assemblies 200 of the manufacturing tool 10 can not only position the main beam 201 of the semi-trailer frame 20 in the Y direction and the Z direction through the main beam positioning part 300, but also position the side beam 202 of the semi-trailer frame 20 in the Y direction and the Z direction through the side beam positioning part 400, and can also use its base 210 to position the position of the semi-trailer frame 20 in the X direction. Therefore, the multiple longitudinal beam positioning assemblies 200 cooperate with each other to realize the flexible positioning of the frame 20 in the X direction, the Y direction and the Z direction, so that the manufacturing tool 10 can be applied to the assembly and production of frames 20 of various vehicle models.

[0137] The manufacturing tool 10 has a beam positioning portion 300 that can be adaptively adjusted in the Y direction according to the size of the beam 201 of the frame 20 of different vehicle models, thereby helping to expand the use scope of the manufacturing tool 10 and improve its versatility.

[0138] The manufacturing tool 10 has a side beam positioning portion 400 that can be adaptively adjusted in the Y direction and the Z direction according to the side beam 202 position of the frame 20 of different vehicle models, thereby helping to expand the use scope of the manufacturing tool 10 and improve its versatility.

[0139] In the manufacturing tool 10, each longitudinal beam positioning assembly 200 can realize the commonality of the main structure (i.e., the base 210) with each other. In other words, the base 210 of each longitudinal beam positioning assembly 200 can be used universally. In the specific implementation process, it is only necessary to connect the corresponding beam positioning part 300 and / or the side beam positioning part 400 on the base 210 according to the needs of positioning the beam 201 or the side beam 202. In addition, the base 210 of the longitudinal beam positioning assembly 200 can also be used alone. There is no need to spend time designing and manufacturing a large number of positioning assemblies with different structures, which effectively reduces the design and manufacturing costs.

[0140] The manufacturing tool 10 is further provided with a beam positioning assembly 500 for supporting and positioning the frame beam 203. By making each beam positioning assembly 500 slidably arranged on the positioning longitudinal beam 130, each beam positioning assembly 500 can move on the positioning longitudinal beam 130 along the X direction, thereby realizing the positioning of the frame beam 203 of different vehicle models in the X direction, and broadening the application scope of the manufacturing tool 20.
