DETAILED DESCRIPTION

[0029] 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.

[0030] In order to further illustrate the principle and structure of the present invention, preferred embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0031] The present invention provides a frame assembling tool 1 for assembling a semitrailer frame 2.

[0032] The semi-trailer frame 2 (hereinafter referred to as the frame) mainly includes a frame body, a through beam and a frame. The frame body mainly includes two longitudinal beams 21 arranged in parallel at intervals. The frame includes two side beams 22 and two sealing frames 23. The side beams 22 are parallel to the longitudinal beams 21, and the two side beams 22 are respectively located on the outside of the two longitudinal beams 21, that is, the two longitudinal beams 21 are located between the two side beams 22. The sealing frame 23 is connected between the two side beams 22, and the two sealing frames 23 and the two side beams 22 enclose a square frame. The through beam passes through the two longitudinal beams 21 and is vertically connected to the two side beams 22.

[0033] The frame assembly tool 1 of the present invention can lift the frame body, facilitate the installation of the through-beam, and the frame assembly work can also perform Z-axis positioning on the frame, which facilitates the assembly of the frame without manual assistance, thereby improving the assembly efficiency of the frame.

[0034] The frame assembly tool 1 is described in detail below.

[0035] See also Figure 1-Figure 4 The frame assembly tool 1 includes an assembly platform 11, a lifting device 12, a frame body pressing device 13 and a frame pressing device 14.

[0036] The assembly platform 11 includes a front assembly platform 111 and a rear assembly platform 112, and the front assembly platform 111 and the rear assembly platform 112 are arranged along the length direction of the assembly platform 11. For the convenience of explanation, the length direction of the assembly platform 11 is defined to be consistent with the length direction of the frame, and the width direction of the assembly platform 11 is consistent with the width direction of the frame. In this embodiment, there is a gap between the front support platform and the rear support platform.

[0037] The front end support platform and the rear end support platform have substantially the same structure, corresponding to the front end and the rear end of the vehicle frame, so as to respectively support the front frame and the rear frame of the vehicle frame.

[0038] The support surface of the front support platform is adjustable relative to the support surface of the rear support platform, so that the assembly platform 11 can adapt to different types of vehicle frames.

[0039] Specifically, the rear end support platform includes a base 114 , a guide rail 115 and a crossbeam 116 .

[0040] The base 114 is the foundation of the rear support platform and is installed on the platform. The platform can be the ground or a mounting platform at a certain height from the ground. A mounting hole is provided in the middle area of ​​the base 114. In this embodiment, the mounting hole is square, and the length direction of the mounting hole extends along the width direction of the base 114.

[0041] The guide rail 115 is fixed to the upper surface of the base 114 and extends along the length direction of the base 114. In this embodiment, the number of the guide rails 115 is two, and the two guide rails 115 are arranged in parallel and spaced apart in the middle of the base 114. Specifically, each guide rail 115 includes two guide rail sections, and the two guide rail sections are respectively located on both sides of the mounting hole. Both guide rail sections extend along the length direction of the base 114 and are located on the same straight line. In other embodiments, the number of the guide rails 115 can also be three or more, and the arrangement of the guide rails 115 can be set according to actual needs.

[0042] A plurality of cross beams 116 are arranged in parallel and spaced apart along the length direction of the base 114. Specifically, the cross beam 116 extends along the width direction of the base 114, and the bottom of the cross beam 116 has two sliders, which are respectively arranged corresponding to the two guide rails 115, so that the cross beam 116 is slidably connected to the base 114, so that when the through beam is inserted, the cross beam 116 can be slid to avoid interference with the through beam. The sliding of the cross beam 116 can adapt to different types of frames.

[0043] Furthermore, a positioning beam 117 is connected to the base 114, and the positioning beam 117 extends along the length direction of the base 114 and is located at the side of the base 114. The positioning beam 117 is connected to a cylinder 118, and when the cylinder 118 is activated, the positioning beam 117 moves along the width direction of the base 114 to make the positioning beam 117 approach or move away from the side beam 22 of the rear frame located on the rear end assembly platform 112, thereby positioning the side beam 22 in the Y direction.

[0044] The structures of the front support platform and the rear support platform are roughly the same, except that the front support platform also includes a lifting cylinder 119, which is arranged at the bottom of the base 114, and can raise or lower the base 114 to achieve the adjustable support surface of the front support platform relative to the support surface of the rear support platform. In this embodiment, there are four lifting cylinders 119, which are respectively located at the four corners of the base 114. The other structures of the front support platform and the rear support platform are the same, and can be referred to the rear support platform, which will not be described one by one here.

[0045] See again Figure 1 and Figure 2 Two lifting devices 12 are arranged at intervals along the length direction of the assembly platform 11. Specifically, a lifting device 12 is arranged on each of the front assembly platform 111 and the rear assembly platform 112 to lift the frame together. In other embodiments, the number of the lifting devices 12 can also be three, four or more, and the distribution of the lifting devices 12 can also be set as needed.

[0046] See also Figure 5 and Figure 6The lifting device 12 includes a support plate 121 and a first lifting mechanism 122. The support plate 121 is lifted by the first lifting mechanism 122, and the frame body on the support plate 121 is lifted, so that the frame body is lifted upwardly beyond the base 114.

[0047] The first lifting mechanism 122 includes a mounting plate 1221 , a connecting plate 1223 , a guide plate 1222 and a power member 1224 .

[0048] The mounting plate 1221 is fixed in the mounting hole of the base 114. A plurality of through holes are formed on the mounting plate 1221. The plurality of through holes are distributed at intervals along the width direction of the base 114.

[0049] The connecting plate 1223 is vertically connected to one side of the mounting plate 1221 and extends upward. In other implementations, the number of connecting plates 1223 can also be two, connected to both sides of the mounting plate 1221. The connecting plate 1223 can also be connected to the end of the mounting plate 1221.

[0050] The guide plate 1222 is connected to the top end of the connecting plate 1223, and the guide plate 1222 is parallel to the mounting plate 1221 and is located above the mounting plate 1221. Specifically, an opening is opened in the middle of the guide plate 1222.

[0051] The multiple power members 1224 correspond to the multiple through holes on the mounting plate 1221 one by one. Specifically, the power members 1224 are fixedly connected to the mounting plate 1221. In this embodiment, the power member 1224 includes four cylinders, and the four cylinders are arranged in a row. Each cylinder includes a cylinder barrel and a lifting rod 1228, and the cylinder barrel is fixedly connected to the mounting plate 1221. The lifting rod 1228 passes through the through hole and extends upward. In other embodiments, the number of cylinders can also be set as needed, and the arrangement of the cylinders can also be set as needed.

[0052] The support plate 121 is connected to the top ends of the plurality of lifting rods 1228, and the support plate 121 is parallel to the base 114 and is located above the guide plate 1222, that is, the lifting rods 1228 pass through the openings of the guide plate 1222 and are connected to the support plate 121. Therefore, the lifting rods 1228 are restricted to move in the openings of the guide rods when moving up and down.

[0053] The principle of lifting the frame body by the lifting device 12 is as follows:

[0054] The power member 1224 is started, and the lifting rod 1228 moves upward in the opening of the guide plate 1222, and the support plate 121 connected to the top of the lifting rod 1228 rises and extends upward beyond the base 114, so that the frame body is located on the support plate 121 and extends upward beyond the base 114, so that when the through beam is passing through the longitudinal beam 21, it will not interfere with the base 114 and the cross beam 116 located below the support plate 121, thereby facilitating the passing of the through beam through the longitudinal beam 21, thereby improving the assembly efficiency of the frame.

[0055] See again Figure 1 and Figure 2 Two frame body clamping devices 13 are arranged at intervals along the length direction of the assembly platform 11, and the two frame body clamping devices 13 are arranged at intervals from the two lifting devices 12. Specifically, a frame body clamping device 13 is respectively arranged on the front assembly platform 111 and the rear assembly platform 112, and they jointly clamp the longitudinal beam 21 of the frame body. In other embodiments, the number of the frame body clamping devices 13 can also be three, four or more, and the distribution of the frame body clamping devices 13 can also be set as needed.

[0056] In this embodiment, the frame body clamping device 13 is installed on the cross beam 116, so it can slide with the sliding of the cross beam 116, thereby adjusting the position of the frame body clamping device 13. In other embodiments, the frame body clamping device 13 can also be directly installed on the base 114.

[0057] See also Figure 7 , Figure 8 and Fig. 9 The frame body clamping device 13 includes two frame body clamping mechanisms 131 and a second lifting mechanism 132 .

[0058] The frame body pressing mechanism 131 includes two frame body pressing members and a telescopic assembly for driving the two frame body pressing members to gather or separate.

[0059] The two frame body clamping members are arranged along the width direction of the assembly platform 11. When the two frame body clamping members are gathered together, the two frame bodies are located between the two longitudinal beams 21 and will not interfere with the two longitudinal beams 21. When the two frame bodies are separated, the two frame bodies correspond to the two longitudinal beams 21 respectively and are located above the two longitudinal beams 21 to be able to clamp the longitudinal beams 21. In this embodiment, the two frame body clamping members are symmetrically arranged about the transverse center line of the assembly platform 11.

[0060] Each frame body pressing member includes a square housing 1311 and a roller 1316 located on the inner side of the housing 1311. The housing 1311 includes two horizontal plates and two vertical plates, which are connected to each other to enclose the square housing 1311.

[0061] The rollers 1316 are connected to the inner side surfaces of the two vertical plates. In this embodiment, along the vertical direction, two groups of rollers 1316 are arranged at intervals on each vertical plate, and each group of rollers 1316 includes two rollers 1316 arranged at intervals along the horizontal direction, that is, four rollers 1316 are arranged on each vertical plate, and the four rollers 1316 are arranged in two horizontal rows. In other embodiments, the rollers 1316 on each vertical plate can be set in a corresponding number and arrangement as needed, or the rollers 1316 can be set on the vertical plate on one side.

[0062] The telescopic assembly includes a base 1312 and a driving member 1313 .

[0063] The base 1312 is located inside the two shells 1311. Specifically, the base 1312 includes a bottom plate and a top plate arranged in parallel and spaced apart, a side plate vertically connected between the bottom plate and the top plate, two side plates located on the inner side surfaces of the two vertical plates, and the top plate and the bottom plate respectively located on the inner side surfaces of the two horizontal plates.

[0064] The two ends of the bottom plate extend beyond the side plates, and the two ends of the top plate extend beyond the side plates. A guide rail for the roller 1316 to move is formed between the outer side of the side plate and the top plate, and between the outer side of the side plate and the bottom plate. That is, two sets of guide rails are arranged in the vertical direction, and each set of guide rails includes two guide rails along the horizontal direction, which are arranged in two horizontal rows and arranged corresponding to the roller 1316. Specifically, in the vertical direction, the two rollers 1316 are located between the top plate and the bottom plate. In the horizontal direction, the two rollers 1316 are located on the outer side of the side plate.

[0065] The driving member 1313 is connected to the housing 1311 to drive the housing 1311 to move. In this embodiment, the driving member 1313 is a handle connected to the end of the housing 1311. The handle is pulled or pushed by external force to move the rollers 1316 of the two housings 1311 along the guide rail to bring the two housings 1311 together or apart.

[0066] In other embodiments, the roller 1316 can also be set at the bottom of the shell 1311, the base 1312 is plate-shaped, and the guide rail is set on the upper surface of the base 1312. The roller 1316 slides with the guide rail to achieve a sliding connection between the shell 1311 and the base 1312.

[0067] The second lifting mechanism 132 is connected to the base 1312 to drive the base 1312 to move up and down. In this embodiment, the second lifting mechanism 132 is a cylinder, which includes a cylinder barrel and a lifting rod. The cylinder barrel is fixedly connected to the cross beam 116, and the lifting end of the lifting rod is fixedly connected to the bottom plate of the base 1312 to drive the base 1312 to move up and down.

[0068] In this embodiment, a fixing plate is connected to the bottom of the middle of the base 1312, and the fixing plate is fixedly connected to the base 1312 and connected to the lifting end of the lifting rod to realize the connection between the second lifting mechanism 132 and the base 1312. The fixing plate extends downward beyond the housing 1311.

[0069] The working principle of the frame body clamping device 13 is as follows:

[0070] The initial state of the vehicle frame body clamping device 13 is that the two shells 1311 are close to each other, so as to avoid interference with the longitudinal beam 21 when the vehicle frame body moves.

[0071] When it is necessary to press the frame body, the second lifting mechanism 132 is started to raise the base 1312, and the frame body pressing piece is raised along with the base 1312 and exceeds the frame body upward; then the handle is pulled, and the rollers 1316 of the two shells 1311 move along the guide rails to move the two shells 1311 away from each other, so that the two shells 1311 are respectively located above the two longitudinal beams 21, and the second lifting mechanism 132 is started to lower the frame body pressing piece, so that the frame body is pressed on the assembly table 11.

[0072] The frame pressing device 14 includes a side beam 22 pressing device and a sealing frame 23 pressing device.

[0073] The side beam 22 clamping devices are arranged at intervals along the length direction of the assembly platform 11, and are used to clamp the side beam 22. In this embodiment, the side beam 22 clamping devices are arranged at both ends of the cross beam 116. And the side beam 22 clamping devices can move with the movement of the cross beam 116, and can adapt to different frames.

[0074] See also Fig.10 and Fig.11 The side beam 22 pressing device includes a frame pressing mechanism and a third lifting mechanism 142.

[0075] The frame pressing mechanism includes a fixed plate 1411, a moving assembly and a frame pressing member.

[0076] The fixing plate 1411 is fixedly connected to the end of the cross beam 116. In this embodiment, the fixing plate 1411 extends along the width direction of the assembly platform 11 and is overlapped and connected with the wing plate of the cross beam 116.

[0077] A guide rail 1412 extending along the width direction of the assembly platform 11 is provided on the fixing plate 1411 .

[0078] The moving assembly includes a guide rail 1412 and a slider 1413. The guide rail 1412 is disposed on the fixed plate 1411 and extends along the width direction of the assembly platform 11.

[0079] The slider 1413 is slidably matched with the guide rail 1412. The slider 1413 is pushed or pulled by manpower. The slider 1413 can also be moved by a motor.

[0080] Furthermore, a connecting member is provided on the other side of the slider 1413 relative to the guide rail 1412. The connecting member includes a vertically arranged connecting plate and a supporting plate perpendicular to the mounting portion, the supporting plate is vertically connected to the vertical plate, and a through hole is provided on the supporting plate. The connecting plate is fixedly connected to the slider 1413.

[0081] The frame pressing member includes a cantilever 1415 and a pressing head 1414 .

[0082] The cantilever 1415 is fixedly connected to the slider 1413 and can move with the movement of the slider 1413. The end of the cantilever 1415 has a mounting hole. In this embodiment, there are two cantilever 1415, which are arranged in parallel. A connecting arm 1416 is connected between the two cantilever 1415.

[0083] The pressure head 1414 is connected to the ends of the two cantilevers 1415 and protrudes downward. In this embodiment, the pressure head 1414 includes a main body and a connecting portion disposed on both sides of the main body and protruding upward. The main body is plate-shaped. The width of the connecting portion gradually decreases in the direction away from the main body.

[0084] The top end of each connecting part is provided with a mounting groove, and the side walls on both sides of the mounting groove are provided with connecting holes.

[0085] The two cantilevers 1415 are placed in the mounting grooves of the two connecting parts in a one-to-one correspondence, and the fasteners penetrate the mounting holes on the cantilevers 1415 and the connecting holes on the connecting parts.

[0086] The third lifting mechanism 142 is connected to the connecting arm 1416 to drive the connecting arm 1416 to move up and down. In this embodiment, the third lifting mechanism 142 is a cylinder, which includes a cylinder barrel and a lifting rod. The cylinder barrel is fixedly connected to the slider 1413, and the lifting end of the lifting rod passes through the through hole on the supporting plate and is fixedly connected to the bottom of the connecting arm 1416 to drive the cantilever 1415 and the pressure head 1414 to move up and down.

[0087] The working principle of the side beam 22 clamping device is as follows:

[0088] The initial state of the side beam 22 pressing device is that the pressing head 1414 is away from the side beam 22 to avoid interference with the side beam 22 when the frame body moves.

[0089] When the side beam 22 needs to be compressed, the slider 1413 is pushed, and the slider 1413 moves along the guide rail 1412 so that the pressure head 1414 is located directly above the side beam 22. The third lifting mechanism 142 is started to lower the connecting arm 1416, driving the pressure head 1414 to lower, and the longitudinal beam 21 is compressed onto the assembly table 11 through the pressure head 1414.

[0090] The sealing frame 23 pressing devices are arranged at intervals along the width direction of the assembly platform 11, and are used to press the sealing frame 23. In this embodiment, the sealing frame 23 pressing devices are located on the inner side of the cross beam 116 at the end.
