[0063] As shown in Figure 2 and Figure 4 ​As shown, the multi-model flexible painting skid of this utility model has a first direction X extending along the length direction of the vehicle body and a second direction Y extending along the width direction of the vehicle body. Generally, the first direction X extending along the length direction of the vehicle body and the second direction Y extending along the width direction of the vehicle body constitute a transverse working plane, and the positioning pin 210 points vertically perpendicular to the transverse working plane.

The drive component can be an electric drive component, a pneumatic drive component, a hydraulic drive component, etc., and can drive the positioning pin 210 to a predetermined position by setting a predetermined rotation angle, forming the required fulcrum. For example, a turntable can be provided at the bottom of the drive component, and positioning is achieved through a positioning keyway on the turntable. The positioning keyway can be increased or decreased according to the required dimensions of the vehicle model. Auxiliary positioning structures 300 and 400 are connected to the base frame 110.

[0066] The base frame 110 of the skid body 100 includes a first side beam 111 and a second side beam 112. The first side beam 111 and the second side beam 112 are arranged parallel to each other along the first direction X, that is, the first side beam 111 and the second side beam 112 extend along the length direction of the vehicle body.

[0067] The first crossbeam 120 and the second crossbeam 130 are arranged along the second direction Y and connected to the first side beam 111 and the second side beam 112. The first side beam 111, the second side beam 112, the first crossbeam 120, and the second crossbeam 130 are connected in a grid pattern.

[0068] Specifically, the first crossbeam 120 includes a first end 121 and a second end 122 opposite to each other, and the positioning pin mechanism 200 includes a first positioning pin mechanism 201 and a second positioning pin mechanism 202 respectively connected to the first end 121 and the second end 122. In other words, the first positioning pin mechanism 201 is connected to the first end 121 of the first crossbeam 120, and the second positioning pin mechanism 202 is connected to the second end 122 of the first crossbeam 120.

[0069] The second cross beam 130 comprises opposite third and fourth end portions 131 and 132, and the positioning pin mechanism 200 comprises a third positioning pin mechanism 203 and a fourth positioning pin mechanism 204 connected to the third and fourth end portions 131 and 132, respectively. Alternatively, the third positioning pin mechanism 203 is connected to the third end portion 131 of the second cross beam 130, and the fourth positioning pin mechanism 204 is connected to the fourth end portion 132 of the second cross beam 130. The first, second, third and fourth positioning pin mechanisms 201, 202, 203 and 204 are of the same structure.

Of course, in other embodiments, the first distance D1 and the second distance D2 can be set to be unequal, and the third distance D3 and the fourth distance D4 can be set to be unequal. The present utility model realizes different first, second, third and fourth distances D1, D2, D3 and D4 by rotating the first, second, third and fourth positioning pins 211, 212, 213 and 214 to different positioning positions, thereby adapting to various vehicle models.

[0072] In some embodiments of the multi-vehicle model flexible coating skid of the present utility model, the first cross beam 120 can rotate by 180 degrees relative to the chassis 110. The positioning pin 210 of the present utility model rotates in multiple positions, and the rotation of the first cross beam 120 allows the support points on the skid body 100 to be adjusted within a certain range in the first and second directions X and Y, thereby realizing multi-vehicle model collinear production of not less than six vehicle body chassis structures.

[0073] The first cross beam 120 is connected with the chassis 110 through a rotating mechanism, which drives the first cross beam 120 to rotate 180 degrees relative to the chassis 110. Figure 2 and 5 As shown in the first end portion 121 of the first cross beam 120 and the third end portion 131 of the second cross beam 130 are located on the same side, that is, the first positioning pin 211 arranged on the first end portion 121 and the third positioning pin 213 arranged on the third end portion 131 are located on the same side and have a third distance D3. The second end portion 122 of the first cross beam 120 and the fourth end portion 132 of the second cross beam 130 are located on the same side, that is, the second positioning pin 212 arranged on the second end portion 122 and the fourth positioning pin 214 arranged on the fourth end portion 132 are located on the same side and have a fourth distance D4.

[0074] As shown in the first end portion 121 of the first cross beam 120 and the third end portion 131 of the second cross beam 130 are located on the same side, that is, the first positioning pin 211 arranged on the first end portion 121 and the third positioning pin 213 arranged on the third end portion 131 are located on the same side and have a third distance D3. The second end portion 122 of the first cross beam 120 and the fourth end portion 132 of the second cross beam 130 are located on the same side, that is, the second positioning pin 212 arranged on the second end portion 122 and the fourth positioning pin 214 arranged on the fourth end portion 132 are located on the same side and have a fourth distance D4. Figure 5 and Figure 6 As shown in the first end portion 121 of the first cross beam 120 and the third end portion 131 of the second cross beam 130 are located on the same side, that is, the first positioning pin 211 arranged on the first end portion 121 and the third positioning pin 213 arranged on the third end portion 131 are located on the same side and have a third distance D3. The second end portion 122 of the first cross beam 120 and the fourth end portion 132 of the second cross beam 130 are located on the same side, that is, the second positioning pin 212 arranged on the second end portion 122 and the fourth positioning pin 214 arranged on the fourth end portion 132 are located on the same side and have a fourth distance D4.

[0075] In some embodiments of the multi-vehicle flexible coating skid of the utility model, the first cross beam 120 is movably and detachably connected with the chassis 110, and the utility model further comprises a hoisting and rotating device, for example, a crane. The first cross beam 120 separated from the chassis 110 is hoisted by the crane, rotated 180 degrees, and then connected with the chassis 110. Similarly, the positioning distance in the first direction X along the length direction of the vehicle body can be changed.

[0076] Preferably, the first cross beam 120 comprises a hoisting portion matched with the hoisting and rotating device, which is beneficial to hoisting and adjustment. The hoisting portion can be a hook, a groove, a through hole or other structures facilitating hoisting and connection.

[0077] In summary, the multi-vehicle flexible coating skid of the utility model adopts multi-position rotatable positioning pins as main supports and positioning points, and realizes flexible positioning through rotation. The adjustment range of the second direction Y is, for example, 1368mm to 1768mm. The multi-position rotatable positioning pins can be further upgraded to stepless rotation full-position positioning pins to realize greater flexibility. The first direction X adjustment can be realized by setting the first cross beam 120 to rotate by 180 degrees, and on this basis, further fine adjustment is made through the positioning pin 210 according to the needs of vehicle model changes. Through the above, the utility model can realize flexible collinear production of vehicle models of different lengths and widths, as well as front-drive vehicles, rear-drive vehicles, four-wheel drive vehicles, electric vehicles and other oil vehicles and electric vehicles.

[0078] The flexible skid has wide application prospects. First, it can meet the collinear production of new vehicle models, avoid the need to modify the skid every time a vehicle model is added, reduce hardware costs and labor costs, and reduce the impact on existing vehicle models and debugging work. Second, replacing the complex and heavy multi-support skid with a more lightweight and simple four-pin positioning flexible skid can reduce the weight by about 30%, save about 240,000 cubic meters of baking gas for coating ovens according to an annual production of 150,000 vehicles, and reduce carbon emissions by an estimated 456 tons per year.

[0079] Of course, the utility model can also have other various embodiments, and those skilled in the art can make various corresponding changes and modifications according to the utility model without departing from the spirit and essence of the utility model. However, these corresponding changes and modifications should all belong to the protection scope of the claims attached to the utility model.
