[0045] In order to keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of well-known functions and well-known components are omitted.

[0046] like Figures 1 to 7As shown, an embodiment of the present invention discloses an auxiliary device for marking, which is placed at a station corresponding to the marking process. The auxiliary device is particularly advantageous when applied to a horizontal conveying line for horizontally conveying assembly components 100. The auxiliary device includes: a platform 10, a bearing mechanism 20, a fixed plate 41, a first movable plate 42, and a first driving mechanism. The platform 10 (located on a frame 12 formed by welding the right beam) is arranged below the horizontal conveying line and is placed at a station corresponding to the marking process (hereinafter referred to as the marking station), specifically, it is arranged in front of the process of assembling two workpieces using bolts 101 (the conveying direction is forward). The bearing mechanism 20 includes a retaining sleeve 22, a disc 21, a rotating shaft 23, and a rolling bearing 24. The disc body 21 is located above the retaining sleeve 22, the upper end of the rotating shaft 23 is connected to the disc body 21, and the lower end of the rotating shaft 23 extends into the retaining sleeve 22. The rolling bearing 24 is installed between the retaining sleeve 22 and the rotating shaft 23, and limits the axial (vertical) movement of the rotating shaft 23. In this way, the disc body 21 can move vertically synchronously with the retaining sleeve 22, and can rotate smoothly by means of the rolling bearing 24. The fixed plate 41 is fixed below the platform 10. Specifically, the fixed plate 41 is fixed below the platform 10 by means of a first guide shaft 33 that is fixedly connected between the platform 10 and the fixed plate 41. The first movable plate 42 is located between the fixed plate 41 and the platform 10. The first guide shaft 33 passes through the first movable plate 42 to guide the vertical movement of the first movable plate 42. The lower end of the retaining sleeve 22 of the above-mentioned bearing mechanism 20 is fixed on the first movable plate 42. The first cylinder 30 is selected as the first driving mechanism, the cylinder body 31 of the first cylinder 30 is fixed under the fixed plate 41, and the piston rod 32 of the first cylinder 30 passes through the fixed plate 41 and is connected to the first movable plate 42. The first cylinder 30 drives the first movable plate 42 to move vertically by pressurized gas, so as to drive the disc 21 on the bearing mechanism 20 to move vertically, and the moving stroke of the disc 21 is set to be able to move to a position higher than the platform 10 by moving upward, and to move to a position lower than the platform 10 by moving downward. It is easy to understand that in order to enable the disc 21 to pass through the platform 10, a hollow portion 11 is opened at the position corresponding to the platform 10 and the disc 21.

[0047] The advantages of the above embodiments of the present invention are:

[0048] Before the horizontal conveying line conveys the assembly component 100 to the marking station, the first cylinder 30 is used to move the disk 21 down to a position lower than the assembly component 100, so that the assembly component 100 can be conveyed to the top of the disk 21; after the assembly component 100 is conveyed to the disk 21 and stops moving, the first cylinder 30 is used to move the disk 21 up to carry the assembly component 100, so that the assembly component 100 can be rotated by the disk 21. At this time, by rotating the assembly component 100 or rotating the disk 21, the bolts 101 on the circumferentially arranged assembly components 100 can be checked in turn, and the bolts 101 can be marked to complete the marking process.

[0049] The present invention configures the disk 21 to be capable of both self-rotation and vertical movement, so that the assembly component 100 can move horizontally to the top of the disk 21 by the downward movement of the disk 21, and be supported by the disk 21 by the upward movement of the disk 21, and the scribing process is completed by the rotation of the disk 21.

[0050] The present invention provides an auxiliary device for the case where an assembly component 100 is placed on a supporting member 102 (such as a tooling plate) and transported by a horizontal transport line. In addition to the above structural features, the auxiliary device also has the following structural features:

[0051] The auxiliary device is also provided with a second movable plate 43 and a second driving mechanism. Specifically, the second movable plate 43 is placed above the platform 10, and a second cylinder 50 is selected as the second driving mechanism. The cylinder body 31 of the second cylinder 50 is fixed to the bottom of the platform 10, and the piston rod 52 of the second cylinder 50 passes through the platform 10 and is connected to the second movable plate 43. The second cylinder 50 drives the second movable plate 43 to move vertically by means of pressurized gas. In some preferred embodiments, a second guide shaft 53 is fixed to the bottom of the second movable plate 43, and the second guide shaft 53 passes through the platform 10 and guides the vertical movement of the second movable plate 43 by vertical movement. In this embodiment, the second movable plate 43 is vertically aligned with the first movable plate 42.

[0052] Preferably, a positioning structure 431 is further provided on the second movable plate 43, specifically a positioning column.

[0053] The working process of the auxiliary device provided in the above embodiment is introduced below:

[0054] like Figure 4 As shown, before the assembly component 100 placed on the supporting member 102 is transported to the marking station by the horizontal conveyor line, the auxiliary device uses the first cylinder 30 and the second cylinder 50 to respectively make the plate 21 and the second movable plate 43 in the low position. The specific standard is: Figure 4As shown, the supporting member 102 and the device assembly can move to above the tray 21 without being blocked by the tray 21 and the second movable plate 43 .

[0055] After the supporting member 102 and the assembly component 100 are transported to the top of the tray 21 and stop moving, Figure 6 As shown, the second movable plate 43 is moved upward by means of the second cylinder 50 to contact the supporting component 102 and thus carry the assembly component 100 , and the supporting component 102 is limited by means of the positioning structure 431 to restrict the movement of the supporting component 102 .

[0056] Then, if Figure 7 As shown, the disk body 21 is moved upward with the aid of the second cylinder 50 so that the disk body 21 passes through the supporting part 102 and contacts the bottom of the assembly component 100, and the assembly component 100 is separated from the supporting part 102 by continuing to move upward. At this time, the assembly component 100 can be rotated horizontally to manually check the torque of the bolts 101 on the assembly component 100 in sequence, thereby completing the marking process.

[0057] After the scribing process is completed, the following steps are performed: the tray 21 is moved downward to allow the assembly component 100 to fall back onto the supporting component 102; the second movable plate 43 is moved downward to allow the supporting component 102 and the assembly component to continue to move horizontally along the horizontal conveying line.

[0058] In some preferred embodiments:

[0059] The lower surface of the disk body 21 is provided with a countersunk hole, and the upper end of the rotating shaft 23 extends into the countersunk hole; wherein: the end surfaces of the upper ends of the disk body 21 and the rotating shaft 23 are provided with corresponding pin holes 25 that are offset from the axis center for the pin to pass through. The advantages are: it can limit the relative rotation of the disk body 21 and the rotating shaft 23, and facilitate the disassembly of the disk body 21 and the rotating shaft 23 by lifting force.

[0060] A flange 221 is formed at the lower end of the retaining sleeve 22 , and the flange 221 is coupled to the first movable plate 42 by fasteners.
