[0008] Furthermore, the pre-rolling roller and the final rolling roller are fixed on the roller base in an adjustable height.

[0009] Furthermore, a calibration mechanism is provided below the roller base.

[0010] Furthermore, the calibration mechanism is a calibration probe.

[0011] Furthermore, the roller head body and the connection base are detachably connected, and an auxiliary connection point is also provided at the top of the roller head body.

[0012] The method comprises a roller head body, a connecting base and a roller base; the connecting base is arranged under the roller head body, and the roller base is fixed under the roller head body; the roller base is provided with a pre-rolling roller and a final rolling roller, and the pre-rolling roller and the final rolling roller are symmetrically distributed in a W-shape on the roller base, so as to meet the rolling process under the A-pillar, B-pillar and C-pillar of the vehicle door window frame, and the roller will not interfere with the vehicle parts during the 0-degree rolling operation, and the effect and efficiency of the rolling operation in all positions can be improved at the same time.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] In the description of the present invention, it should be noted that the directions or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside”, etc., are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0024] A special roller head for hidden water-cut hemming of body-in-white doors, such as Figure 1 , 2 As shown, it includes a roller head body 1, a connecting base 2 and a roller base 3; the connecting base 2 is arranged below the roller head body 1, and the roller base 3 is fixed below the roller head body 1; a pre-rolling roller 4 and a final-rolling roller 5 are provided on the roller base 3, and the pre-rolling roller 4 and the final-rolling roller 5 are symmetrically distributed in a W shape on the roller base 3.

[0025] Specifically, it includes a roller head body 1, a connecting base 2 and a roller base 3; the connecting base 2 is arranged below the roller head body 1, and the roller base 3 is fixed below the roller head body 1; the roller base 3 is provided with a pre-rolling roller 4 and a final-rolling roller 5, and the pre-rolling roller 4 and the final-rolling roller 5 are in a W-shaped symmetrically distributed structure on the roller base 3. The special position layout of the W-shaped symmetrically distributed pre-rolling roller 4 and the final-rolling roller 5 can effectively realize the rolling of the water-cutting shielding position, thereby meeting the rolling process below the A-pillar, B-pillar and C-pillar of the door window frame, so as to solve the disadvantages of the current hidden water-cutting hemming.

[0026] As a preferred embodiment of the above, Figure 5 As shown, the pre-rolling roller 4 is an outer conical structure.

[0030] As a preferred embodiment of the above, Figure 1 As shown, the pre-rolling roller 4 and the final rolling roller 5 are fixed on the roller base 3 in an adjustable height.

[0031] Specifically, by means of a structure in which the pre-rolling roller 4 and the final-rolling roller 5 are fixed on the roller base 3 in an adjustable height, the roller head can be applied to more scenarios, thereby further improving its adaptability.

[0032] As a preferred embodiment of the above, Figure 1 As shown, a calibration mechanism 6 is also provided below the roller base 3 .

[0033] Specifically, a calibration mechanism 6 is provided below the roller base 3 to complete the positioning of the roller head and the pre-rolling roller 4 and the final rolling roller 5 during hemming.

[0034] As a preferred embodiment of the above, Figure 1 As shown, the calibration mechanism 6 is a calibration probe.

[0035] As a preferred embodiment of the above, Figure 1 As shown, the roller head body 1 and the connection base 2 are detachably connected, and an auxiliary connection point is also provided at the top of the roller head body 1.

[0036] Specifically, through the detachable connection between the roller head body 1 and the connection base 2, an auxiliary connection point is also provided at the top of the roller head body 1 to facilitate the installation, disassembly and maintenance of the entire roller head.
