Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle manufacturing equipment technology, and in particular to a rolling tool for automotive lettering. Background Technology
[0002] In automobile manufacturing, roller pressing fixtures are commonly used to press and adhere lettering and various labels. Common roller pressing fixtures include a gripping part, a rolling part, a bracket, and a return compression spring. The rolling part is mounted on the bracket and used to press and adhere the lettering or label. The gripping part is for the user to hold. The return compression spring is mounted on the gripping part and connected to the bracket, providing a certain preload to the bracket. When the user uses the roller pressing fixture to press and adhere the lettering, the rolling part and the bracket together overcome the preload of the return compression spring and move towards the rolling part. However, when the rolling part and the bracket move relative to the gripping part, the movement trajectory is prone to deviation, which cannot guarantee effective adhesion to the lettering. Utility Model Content
[0003] Therefore, it is necessary to provide a rolling tool for automotive lettering that can prevent the movement trajectory from easily deviating when the rolling part and the bracket move relative to the gripping part.
[0004] A rolling tooling for automotive lettering includes a rolling part, a gripping part, a bracket assembly, and a guide rail. The guide rail is fixedly connected to the gripping part, and the rolling part is rotatably mounted on the bracket assembly. The bracket assembly slides and engages with the guide rail along a preset direction. An elastic reset member is installed inside the gripping part. The elastic reset member applies a preload force F1 to the bracket assembly in a preset direction toward the rolling part. The rolling part and the bracket assembly can overcome the preload force F1 of the elastic reset member under the action of external force and slide along the guide rail toward the direction closer to the gripping part.
[0005] In one embodiment, the bracket assembly includes a detachably connected mounting bracket and a slider, a rolling part is mounted on the mounting bracket, a guide rail has a groove extending in a preset direction, and the slider is slidably engaged in the groove.
[0006] In one embodiment, the rolling tool for automotive lettering also includes an anti-rotation component. The rolling part has a slot, and the anti-rotation component has a locking pin that can engage or disengage from the slot. When the locking pin engages with the slot, the anti-rotation component locks with the rolling part. When the locking pin disengages from the slot, the rolling part unlocks.
[0007] In one embodiment, the anti-rotation member is fixedly connected to the gripping part, and the locking pin is engaged in the slot. As the rolling part and the bracket assembly overcome the preload F1 of the elastic reset member under the action of external force, they slide along the guide rail toward the direction close to the gripping part, and the slot can move with the rolling part to disengage from the locking pin.
[0008] In one embodiment, the bracket assembly has a through groove, and the anti-rotation component includes a guide block and a connecting plate arranged at an angle. The guide block is slidably mounted in the through groove, and the connecting plate is fixedly connected to one end of the grip portion near the rolling portion.
[0009] In one embodiment, the grip portion has a notch with a side wall and a bottom wall. The bottom wall is disposed toward the rolling portion along a predetermined direction and is used to cooperate with the stop of the bracket assembly. The side wall is perpendicular to the bottom wall and is used to install the guide rail.
[0010] In one embodiment, the rolling tool for automotive lettering also has an assembly channel that connects to a notch. One end of an elastic reset member is installed in the assembly channel, and the other end extends into the notch and connects to a bracket assembly.
[0011] In one embodiment, the rolling tool for automotive lettering also includes an adjusting bolt, which is threaded onto the inner wall of the assembly channel at the end away from the notch and is used to engage with the elastic reset member for limiting.
[0012] In one embodiment, the elastic reset member includes a reset compression spring and a transmission rod, the reset compression spring being mounted in the assembly channel, and the transmission rod acting between the support assembly and the reset compression spring along a predetermined direction.
[0013] In one embodiment, the rolling part includes a roller and a rotating shaft, the rotating shaft being fixedly connected to the support assembly, and the roller being rotatably sleeved on the rotating shaft.
[0014] Compared with the prior art, the rolling tooling for automotive lettering provided in this application, by setting the bracket assembly to slide and engage with the guide rail along a preset direction, can limit the movement of the bracket assembly and the rolling part along the preset direction more smoothly, and avoid deviation of the movement trajectory, thereby helping to ensure effective fit between the rolling part and the lettering.

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.
[0025] Please see Figures 1 to 3 This application provides a rolling tool 100 for automotive lettering. The rolling tool 100 includes a rolling part 10, a gripping part 20, a bracket assembly 30, and a guide rail 40. The guide rail 40 is fixedly connected to the gripping part 20. The rolling part 10 is rotatably mounted on the bracket assembly 30, and the bracket assembly 30 is slidably engaged with the guide rail 40 along a preset direction. The gripping part 20 is equipped with an elastic reset member 21, which applies a preload force F1 to the bracket assembly 30 in a preset direction toward the rolling part 10. The rolling part 10 and the bracket assembly 30 can overcome the preload force F1 of the elastic reset member 21 under the action of external force and slide along the guide rail 40 toward the gripping part 20. It should be noted that the external force refers to the squeezing force F2 between the rolling part 10 and the lettering when the rolling part 10 presses against it. Understandably, by setting the bracket assembly 30 to slide and engage with the guide rail 40 along a preset direction, the bracket assembly 30 and the rolling part 10 can be limited to move more smoothly along the preset direction, thus preventing deviation of the movement trajectory and ensuring effective contact between the rolling part 10 and the letter mark. The preset direction can be configured as the axial direction of the gripping part 20.
[0026] Alternatively, in one embodiment, as Figure 2 and Figure 3 As shown, the bracket assembly 30 includes a detachably connected mounting bracket 31 and a slider 32. The rolling part 10 is mounted on the mounting bracket 31, and the guide rail 40 has a groove 41 extending in a preset direction. The slider 32 is slidably engaged in the groove 41. Optionally, the mounting bracket 31 and the slider 32 are connected by bolts.
[0027] like Figure 2and Figure 3 As shown, the rolling tool 100 for automotive lettering also includes an anti-rotation member 50. The rolling part 10 has a slot 11, and the anti-rotation member 50 has a locking pin 51. The locking pin 51 can engage or disengage from the slot 11. When the locking pin 51 engages with the slot 11, the anti-rotation member 50 is locked to the rolling part 10. When the locking pin 51 disengages from the slot 11, the rolling part 10 is unlocked. In this way, the anti-rotation member 50 can prevent the rolling part 10 from rolling when it is not in use.
[0028] Furthermore, the anti-rotation member 50 is fixedly connected to the gripping part 20, and the locking pin 51 is engaged in the slot 11. As the rolling part 10 and the bracket assembly 30 overcome the preload F1 of the elastic reset member 21 under the action of external force, they slide along the guide rail 40 toward the gripping part 20, and the slot 11 can move with the rolling part to disengage from the locking pin 51. It can be understood that the rolling part 10 can only be unlocked when the squeezing force F2 between the rolling part 10 and the label is greater than the preload F1 of the elastic reset member 21; when the squeezing force F2 between the rolling part 10 and the label is less than the preload F1 of the elastic reset member 21, the anti-rotation member 50 is locked in place with the rolling part 10, and the rolling part 10 cannot rotate. In this way, a sufficiently large squeezing force F2 can be controlled between the rolling part 10 and the label, thereby avoiding the problem that the label is not sticky due to insufficient force when the rolling part 10 rolls along the label surface, resulting in low label sticking efficiency and possible poor adhesion.
[0029] For example, in one embodiment, the number of slots 11 is configured to be multiple, and the multiple slots 11 are evenly spaced along the circumference of the rolling part 10, so that the locking pin 51 can be engaged in any one of the slots 11 to lock the rolling part 10.
[0030] like Figure 2 As shown, the bracket assembly 30 has a through groove 311, and the anti-rotation member 50 includes a guide block 52 and a connecting plate 53 arranged at an angle. The guide block 52 is slidably mounted in the through groove 311, and the connecting plate 53 is fixedly connected to the end of the grip 20 near the rolling part 10. It can be understood that the guide block 52, by sliding along the through groove 311, can also guide the movement trajectory of the bracket assembly 30 and the rolling part 10. Optionally, the through groove 311 is formed in the mounting bracket 31.
[0031] Furthermore, the guide block 52 and the connecting plate 53 are perpendicular to each other, so that the anti-rotation member 50 is L-shaped. The connecting plate 53 can be glued to the gripping part 20 or fixed by screws.
[0032] like Figure 3As shown, the gripping part 20 has a notch 22, which has a side wall 221 and a bottom wall 222. The bottom wall 222 is positioned towards the rolling part 10 along a preset direction and is used to engage with the stop of the bracket assembly 30. The side wall 221 is perpendicular to the bottom wall 222 and is used to mount the guide rail 40. The notch 22 is used to accommodate the guide rail and at least part of the bracket assembly 30, thereby making the structure of the automotive lettering rolling tool 100 more compact and smaller in size. The bottom wall 222, which engages with the stop of the bracket assembly 30, can limit the maximum stroke of the bracket assembly 30 and the rolling part 10 along the preset direction, so as to avoid excessive movement of the bracket assembly 30 and the rolling part 10 towards the gripping part 20 along the preset direction, which would cause the squeezing force F2 between the rolling part 10 and the lettering to be too large and damage the lettering. The guide rail 40 can be mounted to the side wall 221 with screws.
[0033] like Figure 3 As shown, the rolling tool 100 for automotive lettering also has an assembly channel 23, which connects to a notch 22. One end of the elastic reset member 21 is installed in the assembly channel 23, and the other end extends into the notch 22 and is connected to the bracket assembly 30.
[0034] Furthermore, the rolling tooling for automotive lettering also includes an adjusting bolt 60, which is threaded onto the inner wall of the assembly channel 23 away from the notch 22 and is used to limit the engagement with the elastic reset member 21.
[0035] The adjusting bolt 60 is used to adjust the preload F1 of the elastic reset member 21. Specifically, by turning the adjusting bolt 60, the adjusting bolt 60 is moved towards the notch 22, thereby increasing the preload F1 of the elastic reset member 21; or, by turning the adjusting bolt 60, the adjusting bolt 60 is moved away from the notch 22, thereby decreasing the preload F1 of the elastic reset member 21. For example, the value of F1 can be 19N, 20N, 21N, etc., and can be set according to actual needs.
[0036] The elastic reset element 21 includes a reset compression spring 211 and a transmission rod 212. The reset compression spring 211 is installed in the assembly channel 23, and the transmission rod 212 acts between the bracket assembly 30 and the reset compression spring 211 along a preset direction. The reset compression spring 211 is compressed to provide a preload force F1, and the transmission rod 212 is used to transmit the preload force F1 to the bracket assembly 30.
[0037] Furthermore, the transmission rod 212 is provided with a base 213, and a limiting surface 231 is provided in the assembly channel 23. Along the preset direction, the base 213 stops between the limiting surface 231 and the return compression spring 211.
[0038] like Figure 3As shown, the rolling part 10 includes a roller 12, a rotating shaft 13 and a bearing 14. The rotating shaft 13 is fixedly connected to the bracket assembly 30, and the roller 12 is rotatably sleeved on the rotating shaft 13 through the bearing 14.
[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0040] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
