[0029] refer to Figures 1 to 5A vehicle frame connecting rod type assembly tool according to a preferred embodiment of the utility model will be described in detail below, wherein the vehicle frame connecting rod type assembly tool comprises a base 10 and a plurality of support and positioning seats, a clamping mechanism and a clamping and positioning assembly arranged on the top of the base 10; wherein the support and positioning seats are respectively defined as a first support seat 21, a second support seat 22, a third support seat 23 and a fourth support seat 24, and the support and positioning seats are arranged at a predetermined position on the top of the base 10 to respectively support the rear axle 31 of the frame, the inner support plate of the frame 32, a frame seat ring 33 and a frame balancing cylinder 34, that is, according to the shape and structure of the frame, the first support seat 21, the second support seat 22, the third support seat 23 and the fourth support seat 24 are respectively arranged at the top of the base 10 corresponding to the positions of the frame rear axle 31, the frame inner support plate 32, the frame seat ring 33 and the frame balancing cylinder 34, and the frame rear axle 31, the frame inner support plate 32, the frame seat ring 33 and the frame balancing cylinder 34 can be directly placed on these support positioning seats during assembly and welding, so as to play a supporting and positioning role;

[0030] The clamping mechanism includes a support frame 41 and a clamping bracket 42, wherein the support frame 41 is located at one end of the top of the base 10 and close to the outer side of the first support seat 21, and the clamping bracket 42 has a hinged end 43 and a movable end 44. The clamping bracket 42 is hinged to the support frame 41 through the hinged end 43, and the movable end 44 is close to the inner side of the support frame 41, so that after the frame is placed in place, it can rotate inward with the hinge point as the rotation center to clamp the frame rear axle 31 of the frame, thereby clamping and fixing the frame rear axle structure;

[0031] The clamping and positioning assembly includes two groups of first clamping and positioning mechanisms. The first clamping and positioning mechanisms include a first inner support structure 51 and a first outer clamping structure 52, wherein the first inner support structure 51 extends along the width direction of the base 10, and the first inner support structures 51 in the two groups of the first clamping and positioning mechanisms are respectively opposite to the two side plates of the frame inner support plate 32 and the two side plates of the frame balance cylinder 34, and in addition, the first outer clamping structure 52 is symmetrically arranged at both ends of the first inner support structure 51 to respectively cooperate with the first inner support structure 51 to clamp or loosen the two side plates of the frame inner support plate 32 and the two side plates of the frame balance cylinder 34, so as to clamp and fix the frame inner support plate 32 and the frame balance cylinder 34 at the position of the frame inner support plate 32 and the position of the frame balance cylinder 34, thereby facilitating the assembly and welding of the frame.

[0032] In short, the frame linkage assembly tooling provided in the present application is initially positioned through four supporting positioning seats. After the different components or structures of the frame are placed in place, the frame inner support plate 32 and the frame balance cylinder 34 are clamped and fixed respectively through two sets of first clamping and positioning mechanisms, and finally the end of the frame rear axle 31 is clamped and fixed through the clamping mechanism. This can reduce the involvement of manual assistance on the basis of assembling and fixing the various components and structures of the frame, and further reduce the risk of poor positioning accuracy caused by manual assistance, thereby effectively ensuring the assembly and welding quality of the frame.

[0033] In one embodiment, a contoured groove, such as a rectangular groove or an arc groove, is provided on the top of the support and positioning seat. At the same time, the contoured grooves on the first support seat 21, the second support seat 22, the third support seat 23 and the fourth support seat 24 respectively cooperate with the bottom of the frame rear axle 31, the frame inner support plate 32, the frame seat ring 33 and the frame balance cylinder 34, so as to be able to well support the frame rear axle 31, the frame inner support plate 32, the frame seat ring 33 and the frame balance cylinder 34 respectively.

[0034] In one embodiment, the clamping bracket 42 is a steel plate bracket, and the support frame 41 is symmetrically provided with a first positioning hole 401 in the horizontal direction on the inner side of the hinge position, and the clamping bracket 42 is correspondingly provided with a second positioning hole. In addition, the clamping mechanism also includes a positioning pin 45 that cooperates with the first positioning hole and the second positioning hole at the same time, so that when the clamping bracket 42 is pressed on the top of the frame, the positioning pin 45 simultaneously penetrates the first positioning hole 401 and the second positioning hole to fix the clamping bracket 42, so that the stability of the rear axle 31 of the frame during the assembly welding process can be improved by fixing the clamping bracket 42, and problems such as displacement or warping can be avoided, thereby ensuring the assembly welding quality.

[0035] In one embodiment, the clamping and positioning assembly further includes two second inner support structures 53 and second outer clamping structures 54 arranged at both ends of the second inner support structures 53, wherein the two second inner support structures 53 extend along the length direction of the base 10 and are symmetrically distributed on the front and rear sides of the third support seat 23 to cooperate with the second outer clamping structures 54 at both ends to clamp or release the two inner side plates of the frame seat ring 33, wherein the first outer clamping structure 52 and the second outer clamping structure 54 have the same structure, both including an outer support frame 521 and a top Tightening bolt 522, wherein the jacking bolt 522 is horizontally arranged on the top of the outer support frame 521 in a threaded manner, and at the same time, the inner end of the jacking bolt 522 is vertically connected with a tightening boss 523 to increase the contact area and improve the tightening stability. In this way, with the first inner support structure 51 and the second inner support structure 53 as the inner reference positioning position, it is only necessary to rotate the jacking bolt 522 to clamp and fix the frame inner support plate 32, the frame seat ring 33 and the frame balance cylinder 34, or loosen them, and the operation is very convenient.

[0036] More preferably, in combination Figure 4 and Figure 5 The first inner support structure 51 and the second inner support structure 53 have the same structure, both of which include a mounting base 511, an outer support plate 512, an adjustment seat 513 and an adjustment screw 514, wherein the mounting base 511 is fixedly connected to the base 10 and extends along the length direction of the base 10, wherein the outer support plate 512 is symmetrically mounted at both ends of the mounting base 511 in a hinged manner, and at the same time, the other ends of the two outer support plates 512 away from the mounting base 511 are respectively hinged to the adjustment seat 513 through connecting rods 515, wherein the adjustment seat 513 is located directly above the middle position of the mounting base 511, and the adjustment screw 514 penetrates the adjustment seat 513 in a vertical direction in a threaded matching manner, and is threadedly connected to the mounting base 511, so that by rotating the adjusting screw 514, the outer support plate 512 can be offset toward the outside or toward the inside relative to the mounting base 511 under the hinged action of the connecting rod 515.

[0037] Generally, when clamping and fixing the frame, the outer support plate 512 is rotated outward until the outer support plate 512 is kept in the vertical direction to play a positioning role. At this time, it is only necessary to rotate the tightening bolt 522 in the forward direction to clamp the frame structure. When it is necessary to remove the parts, first rotate the tightening bolt 522 in the reverse direction, and then rotate the adjusting screw 514 synchronously to make the outer support plates 512 on both sides deflect inward synchronously, so that the parts can be removed very conveniently.

[0038] Further preferably, a limiting member 516, such as a limiting pin or a limiting block, is provided in the mounting base 511 along the direction of hinged movement of the outer support plate 512, wherein the limiting member 516 is close to the outer side of the hinged position of the mounting base 511 and the outer support plate 512, and is lower than the hinged position in the height direction, so as to limit the outer support plate 512 at the bottom of the outer support plate 512 when the outer edge of the outer support plate 512 maintains a vertical extension direction, thereby enabling the limiting member 516 to play a positioning role, so that the outer support plate 512 can be quickly and accurately moved into place. In addition, the limiting member 516 can also play a limiting role to prevent the outer support plate 512 from tilting excessively to the outside, thereby reducing the contact area with the workpiece so that the outer support plate 512 cannot be maintained in a vertical extension state, and the support stability is poor.

[0039] In order to facilitate the rotation of the adjusting screw 514 , a handle 517 is vertically connected to the top of the adjusting screw 514 , and the handle 517 is located above the adjusting seat 513 .

[0040] In one embodiment, three groups of bearing seats 25 are installed on the top of the fourth support seat 24, and a rotating shaft 26 is connected between each group of the bearing seats 25, wherein the rotating shaft 26 extends along the length direction of the base, and a spacer sleeve 27 is provided in the partial fixed sleeve located between the bearing seats 25, and the frame balance cylinder 34 is supported by the spacer sleeve 27, so that the damage to the frame balance cylinder 34 can be reduced or even avoided during the support process. In addition, based on the function of the bearing seat 25 and the rotating shaft 26, the spacer sleeve 27 that plays a supporting role can also rotate flexibly, so that the frame balance cylinder 34 can be quickly assembled and welded.

[0041] It should be noted that the terms "first, second, third and fourth" in the present invention are only used for descriptive purposes and do not represent any order. They cannot be understood as indicating or implying relative importance. These terms can be interpreted as names.

[0042] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention.
