DETAILED DESCRIPTION

[0032] 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 used for illustration purposes rather than for limiting the present invention.

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.

[0034] 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. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0035] In the manufacturing process of the semi-trailer beam, the beam shape is different due to different models, so the existing tooling cannot adapt to the manufacturing of beams of different models. Therefore, a semi-trailer beam assembly tooling is proposed to solve the above problem.

[0036] like Figure 1 As shown, the existing beam 10 of the semi-trailer is generally in the shape of a gooseneck, and includes a head extension section 11, a neck connection section 12, a gradual connection section 13, and a tail extension section 14 along its own length direction. In this embodiment, the existing beam 10 is formed by splicing and welding an upper wing plate 15, a lower wing plate 16, and a web plate 17, and the web plate 17 is located between the upper wing plate 15 and the lower wing plate 16, so that the cross section of the beam 10 along its width direction is an "I" shape.

[0037] See also Figure 2 In this embodiment, Figure 2 The left and right directions are the longitudinal directions of the semi-trailer beam assembly tooling. Figure 2 The up and down direction is the horizontal direction of the semi-trailer frame assembly tooling.

[0038] The scheme is further illustrated by the following examples:

[0039] See also Figure 2-4 The semi-trailer beam assembly tooling of this embodiment includes a base frame 20, a head clamping mechanism 30, an auxiliary clamping mechanism 40, a gradual clamping mechanism 50 and a neck clamping mechanism 60. The head clamping mechanism 30 is used to clamp on the head extension section 11, the auxiliary clamping mechanism 40 is used to clamp on both sides of the beam 10 in the transverse direction, the gradual clamping mechanism 50 is used to clamp on the gradual connecting section 13, and the neck clamping mechanism 60 is used to clamp on the neck connecting section 12, so as to clamp and position the upper wing plate 15 and the lower wing plate 16 on both sides of the web 17, thereby facilitating the welding of the beam 10, thereby ensuring the welding accuracy of the beam 10 and improving the production efficiency of the beam 10.

[0040] See also Figure 2The base frame 20 extends in the longitudinal direction to install the head clamping mechanism 30, the auxiliary clamping mechanism 40, the gradual clamping mechanism 50 and the neck clamping mechanism 60. In this embodiment, the base frame 20 includes two longitudinal beams 21 extending in the longitudinal direction and a plurality of transverse beams 22 extending in the transverse direction. The two longitudinal beams 21 are arranged in parallel, and the transverse beams 22 are fixed between the two longitudinal beams 21 to form the base frame 20. It should be noted that in some other embodiments, the base frame 20 can also be set as a plate-shaped base.

[0041] See also Figure 3 and Figure 4 In this embodiment, a plurality of head clamping mechanisms 30 are provided, and the plurality of head clamping mechanisms 30 are arranged in parallel along the longitudinal direction, while a single head clamping mechanism 30 is installed on the base frame 20 along the transverse direction, so that the plurality of head clamping mechanisms 30 can clamp different positions of the head extension section 11, thereby ensuring the welding accuracy of the head extension section 11.

[0042] In this embodiment, three head clamping mechanisms 30 are provided to clamp the head extension section 11. It should be noted that in other embodiments, the number of head clamping mechanisms 30 can be set according to actual needs, such as 1, 2, 4, etc.

[0043] In addition, see Figure 6 and Figure 7 The head clamping mechanism 30 includes a head mounting seat 31, two head limiting assemblies 32 and a movable clamping assembly 33. The head mounting seat 31 is fixed on the base frame 20 in the horizontal direction, and the two head limiting assemblies 32 can slide relatively on the head mounting seat 31 in the horizontal direction to adjust the relative position of the head limiting assemblies 32 on the head mounting seat 31, so that the head limiting assemblies 32 can be adapted to the shape of the head extension section 11, thereby meeting the requirements of clamping the head extension sections 11 of different beams 10. That is, after the head limiting assemblies 32 slide to a specific position relative to the head mounting seat 31, the head limiting assemblies 32 are limited to limit the sliding of the head limiting assemblies 32 relative to the head mounting seat 31, so that the head limiting assemblies 32 can abut against the side of the head extension section 11. At the same time, the mobile clamping assembly 33 is installed between the two head limit assemblies 32 so that the head extension section 11 can be pushed laterally between the mobile clamping assembly 33 and the head limit assembly 32, so that the head limit assembly 32 and the mobile clamping assembly 33 can match head extension sections 11 of different sizes, thereby meeting the needs of clamping beams 10 of different sizes.

[0044] In this embodiment, the mobile clamping assembly 33 includes a clamping plate 34, a guide wheel 35, and a mobile telescopic rod 36. The clamping plate 34 extends vertically so that the clamping plate 34 can abut against the side of the head extension section 11 in the horizontal direction. The guide wheel 35 is installed on both sides of the bottom of the clamping plate 34 and can roll along the head mounting seat 31, thereby reducing the friction between the clamping plate 34 and the head mounting seat 31 and improving the moving efficiency. One end of the mobile telescopic rod 36 is connected to the head mounting seat 31, and the other end is connected to the clamping plate 34 to drive the clamping plate 34 to slide on the head mounting seat 31. It should be noted that in this embodiment, the mobile telescopic rod 36 is a cylinder so that the cylinder can drive the clamping plate 34 to move on the head mounting seat 31 in the horizontal direction and abut against the side of the head extension section 11. In some other embodiments, the mobile telescopic rod 36 can also be set as a screw and a motor so that the clamping plate 34 moves under the drive of the screw and the motor.

[0045] It should be noted that, see Figure 6 and Figure 7 The head mounting seat 31 comprises a bottom plate 311, a channel steel 312, a first pad 313, a second pad 314 and a rib 315, wherein the bottom plate 311 is provided with a plurality of connection holes, so as to facilitate fixing the head mounting seat 31 on the base frame 20 through the connection holes and bolts, and the position of the head mounting seat 31 on the base frame 20 can be adjusted according to actual needs. The channel steel 312 is fixed on the bottom plate 311, and the channel steel 312 is provided with a receiving portion 3121 and a groove portion 3122, the mobile clamping assembly 33 is installed in the receiving portion 3121, and the clamping plate 34 can extend out of the groove portion 3122, so that the clamping plate 34 can abut against the side of the head extension section 11. Two first pads 313 are provided, and are arranged and fixed at intervals on the top of the channel steel 312, and are located on both sides of the groove portion 3122. Two second pads 314 are provided, and are fixed on the tops of the two first pads 313 respectively. At the same time, the two opposite sides of the two first pads 313 extend mutually and exceed the side edges of the first pads 313, so that the second pads 314, the first pads 313 and the top of the channel steel 312 form a sliding groove 316 for slidingly connecting the head stop assembly 32. At the same time, two ribs 315 are also provided, and are respectively located on both sides of the top of the second pads 314 in the longitudinal direction, so as to limit the head stop assembly 32.

[0046] In addition, see Figure 7The head limit assembly 32 includes a limit seat 321, an adjusting screw 322, and a screw connecting seat 323, wherein a limit sliding portion 3211 is provided at the bottom of the limit seat 321, and the limit sliding portion 3211 is slidably connected in the slide groove 316 so as to be able to slide and limit relative to the head mounting seat 31 in the transverse direction. The screw connecting seat 323 is also provided with a connecting sliding portion 3231, and is connected in the slide groove 316 through the connecting sliding portion 3231 so as to be able to slide and limit relative to the head mounting seat 31 in the transverse direction. One end of the adjusting screw 322 is connected to the limit seat 321, and the other end is threadedly connected to the screw connecting seat 323, so that the position of the limit seat 321 can be adjusted by rotating the adjusting screw 322.

[0047] It should be noted that a clamping screw 3212 is also provided on the limit seat 321. The clamping screw 3212 is threadedly connected to the limit seat 321, and the clamping screw 3212 is vertically arranged so as to be able to vertically clamp the upper wing plate 15 or the lower wing plate 16 of the beam 10.

[0048] See also Figure 3 , Figure 8 and Fig. 9 , multiple auxiliary clamping mechanisms 40 are arranged in the longitudinal direction, and multiple auxiliary clamping mechanisms 40 are installed in the longitudinal direction on the base frame 20 to clamp on both sides of the beam 10 in the transverse direction. It should be noted that a single auxiliary clamping mechanism 40 is fixed on the base frame 20 in the transverse direction. In addition, in this embodiment, the auxiliary clamping mechanisms 40 are distributed on both sides of the gradual clamping mechanism 50 to be able to clamp both sides of the beam 10.

[0049] In this embodiment, the auxiliary clamping mechanism 40 includes an auxiliary mounting seat 41 and two clamping seats 42. The auxiliary mounting seat 41 is mounted on the base frame 20 in the longitudinal direction, and the two clamping seats 42 can slide relatively and limit on the auxiliary mounting seat 41 in the transverse direction to respectively abut on both sides of the beam 10 in the transverse direction.

[0050] In this embodiment, one of the two clamping seats 42 is provided with a guide wheel 421 and an auxiliary telescopic rod 422, and the other clamping seat 42 has the same structure as the head limiting assembly 32. Among them, the guide wheel 421 is installed at the bottom of the clamping seat 42, and the auxiliary telescopic rod 422 is connected to the clamping seat 42 to drive the clamping seat 42 to slide and limit along the auxiliary mounting seat 41. It should be noted that the structure of the auxiliary mounting seat 41 is the same as that of the head mounting seat 31, so the guide wheel 421 and the auxiliary telescopic rod 422 are both installed in the accommodating portion 3121. Since the structure of the clamping seat 42 is the same as that of the head limiting assembly 32, and the structure of the auxiliary mounting seat 41 is the same as that of the head mounting seat 31, it will not be repeated here.

[0051] See also Figure 8 and Fig. 9, the auxiliary clamping mechanism 40 is provided with a pad 43. The pad 43 is used to support the web 17 of the beam 10 so that the web 17 can be connected between the upper wing plate 15 and the lower wing plate 16 at a specific position. In this embodiment, the pad 43 slides relatively and limits on the auxiliary mounting seat 41 in the lateral direction, and the tops of the pads 43 of the multiple auxiliary clamping mechanisms 40 are on the same horizontal plane, so that the web 17 of the beam 10 is on the same horizontal plane.

[0052] It should be noted that, in the present embodiment, pads 43 are provided on the head clamping mechanism 30 , the auxiliary clamping mechanism 40 , the gradual clamping mechanism 50 and the neck clamping mechanism 60 for supporting the web 17 .

[0053] At the same time, it should be noted that a notch 44 is provided on the second pad 314, and the notch 44 is connected to the slide groove 316, so that the pad 43 can be placed in the slide groove 316 through the notch 44, thereby facilitating the replacement of the pad 43 to support different webs 17.

[0054] See also Figure 3 and Figure 5 The gradual clamping mechanism 50 includes a plurality of gradual clamping units 51 and a gradual abutting unit 52. The plurality of gradual clamping units 51 are longitudinally mounted on the base frame 20 so as to abut against the gradual connecting section 13. It should be noted that a single gradual clamping unit 51 is transversely fixed on the base frame 20 so as to abut against the side of the gradual connecting section 13.

[0055] like Fig.10 and Fig.11 The gradual clamping unit 51 includes a gradual mounting seat 53, a gradual limiting assembly 54 and a gradual positioning assembly 55. The gradual limiting assembly 54 and the gradual positioning assembly 55 can slide relatively and limit in the lateral direction on the gradual mounting seat 53. It should be noted that the gradual mounting seat 53 has the same structure as the head mounting seat 31, and the gradual limiting assembly 54 has the same structure as the head limiting assembly 32, so they will not be described in detail here.

[0056] The gradual positioning assembly 55 is provided with a structure similar to that of the mobile clamping assembly 33, that is, it is also provided with a clamping plate 551, a guide wheel 552 and a mobile telescopic rod 553, and its connection mode and function are the same as those of the mobile clamping assembly 33, so it is not repeated here. However, it should be noted that the gradual positioning assembly 55 is also provided with a connecting member 554, and the connecting member 554 is fixed to the clamping plate 551 so as to be connected to the gradual abutting unit 52.

[0057] In this embodiment, the gradual abutment unit 52 includes a connecting beam 56 and a gradual abutment member 57. The connecting beam 56 is located between the two gradual clamping units 51, and the two ends of the connecting beam 56 in the length direction are respectively hinged to a gradual positioning assembly 55, that is, both ends of the connecting beam 56 are hinged to the connecting member 554, so that the connecting beam 56 can move in the lateral direction under the drive of the gradual positioning assembly 55. The gradual abutment member 57 can slide on the connecting beam 56 along the length direction of the connecting beam 56, and can be limited on the connecting beam 56, that is, the gradual abutment member 57 can adjust its position along the length direction of the connecting beam 56, so as to be able to abut against the side of the gradual connection section 13 at different positions. It should be noted that there are multiple gradual abutment members 57, and they are all installed on the connecting beam 56, so that the gradual abutment unit 52 can abut against the side of the gradual connection section 13 at different positions. Therefore, it can be known that the gradual limiting assembly 54 is used to abut against one side of the gradual connecting section 13, and the gradual abutting member 57 is used to abut against the side of the gradual connecting section 13 facing away from the gradual limiting assembly 54, thereby clamping both sides of the gradual connecting section 13.

[0058] See also Figure 3 , Figure 4 and Fig.12 The neck clamping mechanism 60 includes a plurality of neck limiting units 61 and a neck abutting unit 62. The plurality of neck limiting units 61 are longitudinally mounted on the base frame 20, so that the neck abutting unit 62 can match the shape of the neck connecting section 12 and abut or limit the side of the neck connecting section 12.

[0059] In the present embodiment, the neck limiting unit 61 includes a neck mounting seat 63 and a neck limiting assembly 64. The neck limiting assembly 64 can slide and limit on the neck mounting seat 63 in the horizontal direction, so as to be used to abut against one side of the neck connecting section 12 in the horizontal direction, so that the neck limiting assembly 64 can adjust its position on the neck mounting seat 63 according to actual needs. It should be noted that, in the present embodiment, the neck limiting assembly 64 has the same structure as the head limiting assembly 32, so the neck limiting assembly 64 is not elaborated in detail here. In addition, the neck mounting seat 63 includes a mounting plate 631 and a mounting portion 632, and the mounting plate 631 and the mounting portion 632 are arranged in parallel in the horizontal direction. Among them, the structure of the mounting portion 632 is the same as that of the head mounting seat 31, so it is not repeated here.

[0060] In addition, in the present embodiment, the neck abutting unit 62 is used to abut against the side of the neck connecting section 12 facing away from the neck limiting assembly 64. The neck abutting unit 62 includes a plurality of retractable neck telescopic rods 65 and a neck abutting member 66, and one end of the neck telescopic rod 65 is rotatably connected to the neck mounting seat 63 around an axis in the vertical direction. Specifically, one end of the neck telescopic rod 65 is rotatably mounted on the mounting plate 631, and the neck abutting member 66 is arranged at the other end of the neck telescopic rod 65 to abut against the side of the neck connecting section 12 facing away from the neck limiting assembly 64. Since the neck telescopic rod 65 can rotate relative to the neck mounting seat 63 and can be retracted toward the neck limiting assembly 64, the neck telescopic rod 65 can abut against the side of the neck connecting section 12 facing away from the neck limiting assembly 64 at different positions, and can also meet the requirements of abutting against neck connecting sections 12 of different sizes and shapes.

[0061] It should be noted that, in the present embodiment, the neck telescopic rod 65 is a cylinder.

[0062] like Figure 4 As shown, the neck abutment unit 62 further includes a locking assembly 68 and a locking plate 69. The locking assembly 68 is arranged corresponding to the neck telescopic rod 65, that is, the locking assembly 68 is hinged on one end of the neck telescopic rod 65 facing the neck limiting assembly 64, so as to lock the neck telescopic rod 65 on the neck mounting seat 63 or the locking plate 69, and prevent the neck telescopic rod 65 from rotating relative to the neck mounting seat 63 or the locking plate 69. The locking plate 69 is fixed on the neck mounting seat 63, that is, the locking plate 69 is fixed on the mounting plate 631. In addition, a plurality of locking holes 691 are provided on the locking plate 69 corresponding to each neck telescopic rod 65, and the locking holes 691 are distributed around the axis of the corresponding neck telescopic rod 65, and the locking assembly 68 can be engaged in the locking hole 691 and can be disengaged from the locking hole 691. Thereby, the neck telescopic rod 65 can be clamped on different locking holes 691 through the locking assembly 68 to achieve the purpose of changing the abutting position, thereby enabling the neck telescopic rod 65 and the neck abutting member 66 to abut at different positions of the neck connecting section 12.

[0063] It should be noted that, in this embodiment, the locking assembly 68 includes a connecting portion 681, a locking plate 682 and a locking pin 683. The connecting portion 681 is an arc-shaped connecting steel bar, so that the connecting portion 681 can be sleeved and fixed on the outer peripheral side of the neck telescopic rod 65. The locking plate 682 is connected to the outer peripheral side of the neck telescopic rod 65 through the connecting portion 681, so that the locking plate 682 can be fastened to the outer peripheral side of the neck telescopic rod 65 and can move with the neck telescopic rod 65. At the same time, a through hole is provided on the locking plate 682, and the locking pin 683 is inserted into the through hole of the locking plate 682, and one end of the locking pin 683 can extend into the locking hole 691 of the locking disk 69 and be locked in the locking hole 691, so that the locking pin 683 can limit the rotation of the locking plate 682, the connecting part 681 and the neck telescopic rod 65 relative to the locking disk 69, thereby limiting the neck telescopic rod 65 at a specific position of the locking disk 69, preventing the neck telescopic rod 65 from rotating relative to the locking disk 69.

[0064] It should be noted that, in some other embodiments, the locking assembly 68 can also be configured to be directly connected to the locking protrusion on the circumferential side of the neck telescopic rod 65, and the locking protrusion can extend into the locking hole 691 of the locking disk 69 and be locked in the locking hole 691 to limit the rotation of the neck telescopic rod 65 relative to the locking disk 69.

[0065] See also Figure 4 One end of the neck telescopic rod 65 facing the neck limit assembly 64 is hinged to the neck top piece 66, so that the neck top piece 66 can rotate relative to the neck telescopic rod 65, and there is a gap between the hinge point and the longitudinal ends of the neck top piece 66, so that the neck top piece 66 can better match the arc shape of the neck connecting section 12, and then the neck top piece 66 can better fit and abut against the side of the neck connecting section 12.

[0066] Specifically, the neck abutting member 66 includes two opposite wings 661, the opposite ends of the two wings 661 are connected as one body, and the opposite ends of the two wings 661 are hinged to the neck telescopic rod 65, that is, the connection of the two wings 661 is hinged to the end of the neck telescopic rod 65. In addition, the distance between the two wings 661 gradually increases in the direction away from the neck telescopic rod 65, that is, the two wings 661 are in a "V" shape to abut against the side of the neck connecting section 12.

[0067] In this embodiment, the neck abutting member 66 is further provided with two abutting rollers 662. The abutting rollers 662 are vertically arranged and rotatably connected to the side of the wing 661 facing the neck stop assembly 64, and can abut against the side of the neck connecting section 12, so that when the neck abutting member 66 abuts against the side of the neck connecting section 12, the abutting rollers 662 can roll along the side of the neck connecting section 12 to prevent the end of the neck abutting member 66 from scratching the side of the neck connecting section 12. In this embodiment, the abutting rollers 662 are plastic rollers.

[0068] In summary, the assembly tooling is provided with a head clamping mechanism 30, an auxiliary clamping mechanism 40, a gradient clamping mechanism 50 and a neck clamping mechanism 60, so as to clamp the head extension section 11, the neck connecting section 12, the gradient connecting section 13 and the tail extension section 14 respectively, so that each clamping mechanism can match the shape of each segment of the beam 10, and can adjust the clamping position according to the shape of each segment of different beams 10, so that the splicing tooling can clamp different beams 10, which is convenient for assembling and welding the beams 10.
