[0030] Example 1

[0031] Reference Figures 1 to 6The present embodiment provides an automobile sheet metal conveying device, including a support frame 100, on which a parallel belt 101 is provided, the belt 101 is driven by a drive motor 102, a frame 103 is provided on the support frame 100, and a support roller 200 perpendicular to the belt 101 is provided on the frame 103, the support roller 200 includes a rotatable core shaft 201, a rubber roller 202 is sleeved on the core shaft 201, and a limit member 203 is provided at the end of the core shaft 201 to connect with the rubber roller 202.

[0032] In this embodiment, the bottom of the automobile sheet metal is supported on the support roller 200, which is placed on the belt 101 and transported to the next process under the conveyance of the belt 101. In addition to the support roller 200 playing a supporting role, the rubber roller on it is also used to protect and avoid wear on the sheet metal. At the same time, the friction of the rubber roller is relatively large, which further facilitates the transportation of the sheet metal.

[0033] A first end plate 201a is provided at the end of the core shaft 201, and a first spiral groove 201b is provided on the core shaft 201. The first spiral groove 201b is provided with two lines, and a square groove 201c is provided at the end of the core shaft 201.

[0034] Two first spiral grooves 201 b are provided along the circumference of the core shaft 201 .

[0035] The rubber roller 202 includes a metal core tube 202 a , and a rubber layer 202 b is provided on the outside of the metal core tube 202 a .

[0036] A first spiral line 202c is disposed inside the metal core tube 202a. The length of the core shaft 201 is smaller than that of the rubber roller 202. The first spiral line 202c is screwed into the first spiral groove 201b.

[0037] Likewise, two first spiral strips 202c are provided along the circumferential direction of the metal core tube 202a, so that the first spiral strips 202c can quickly find the joint and be screwed into the first spiral groove 201b.

[0038] A first cavity 202d and a second cavity 202e are respectively provided at both ends of the first spiral line 202c in the metal core tube 202a.

[0039] It should be noted that the arrangement of the first cavity 202d and the second cavity 202e reserves space at the two ends of the metal core tube 202a, and the first spiral line 202c is not arranged in the space.

[0040] The first cavity 202d is used to insert the end of the core shaft 201 into the metal core tube 202a first. If the first spiral line 202c and the end of the first spiral groove 201b correspond, they can be screwed together under axial force. If they do not correspond, the first spiral line 202c and the end of the first spiral groove 201b can be made to correspond during the rotation of the metal core tube 202a. Therefore, the function of the first cavity 202d is preliminary positioning and quick connection of the metal core tube 202a and the core shaft 201.

[0041] A second spiral groove 202f is provided on the inner wall of the second cavity 202e, and an axial side strip 202g is provided at the opening of the second cavity 202e.

[0042] A rotating plate 204 is provided in the metal core tube 202 a . A side shaft 204 a is provided on the side wall of the rotating plate 204 . The side shaft 204 a is embedded in the second spiral groove 202 f . A square hole 204 b is provided on the rotating plate 204 .

[0043] The damaged rubber roller 202 can be recycled and the metal core tube 202a can be reused.

[0044] When the side shaft 204a moves along the second spiral groove 202f, the rotating plate 204 is in a state of both rotating and moving linearly along the axial direction of the metal core tube 202a.

[0045] One side of the rotating plate 204 is connected to the ring plate 204d via a spring 204c.

[0046] Furthermore, a non-slip rubber layer is provided on a side of the ring plate 204 d away from the rotating plate 204 .

[0047] The limiting member 203 includes a plug plate 203a, a baffle 203b and a screw plate 203c. An axial groove 203d is provided on the side wall of the plug plate 203a, and a square rod 203e is provided on one side of the plug plate 203a.

[0048] The axial edge strip 202g is embedded in the axial groove 203d to limit the relative movement between the plug plate 203a and the metal core tube 202a. Specifically, the plug plate 203a can only move along the axial direction of the metal core tube 202a.

[0049] A second end plate 205 is provided between the baffle 203b and the rubber roller 202. A through hole 205a is provided in the middle of the second end plate 205. The second end plate 205 is sleeved on the plug plate 203a. A fillet 205b is provided inside the through hole 205a. The fillet 205b is embedded in the axial groove 203d.

[0050] Specifically, the installation method of the present invention is to insert the first cavity 202d at the end of the rubber roller 202 into the end of the core shaft 201, rotate the rubber roller 202 so that the first spiral line 202c and the end of the first spiral groove 201b correspond to each other, and push the rubber roller 202 along the axial direction to screw the rubber roller 202 and the core shaft 201 together. During this process, the end of the core shaft 201 will contact the side of the anti-slip rubber layer of the ring plate 204d and push the ring plate 204d and the rotating plate 204 together to Figure 4 As shown, the right side moves until the side shaft 204a reaches the rightmost end of the second spiral groove 202f, and then the rotating plate 204 stops moving and the spring 204c is preliminarily compressed.

[0051] At this time, the core shaft 201 has been completely embedded in the metal core tube 202a to achieve connection. It should be noted that the positions of the square groove 201c and the square hole 204b do not correspond to each other, and the angle difference between the two is about 45 degrees.

[0052] Then install the limit piece 203, first put the second end plate 205 onto the plug plate 203a, so that the inserting strip 205b is embedded in the axial groove 203d, and then insert the plug plate 203a into the metal core tube 202a, so that the axial side strip 202g is embedded in the axial groove 203d. At this time, the square rod 203e completely corresponds to the square groove 201c, while the square rod 203e and the square hole 204b do not correspond. Therefore, in the process of inserting the plug plate 203a, the square rod 204c will push the rotating plate 204 to further compress the spring 204c, so that the rotating plate 204 moves along a straight line while rotating until the square hole 204b corresponds to the position of the square rod 204c, then the square rod 204c passes through the square hole 204c, and the end of the square rod 204c is embedded in the square groove 201c.

[0053] Due to the screw connection between the rubber roller 202 and the core shaft 201, the rubber roller 202 needs to be rotated relative to the core shaft 201 to be removed axially. The square rod 204c and the axial groove 203d are respectively connected to the square groove 201c and the axial edge strip 202g, so that the rubber roller 202 and the core shaft 201 cannot rotate relative to each other, thereby ensuring the stability of the connection.

[0054] The spring 204c is in a compressed state, which means that the rotating plate 204 is subjected to axial force, and the movement of the rotating plate 204 requires rotation. Therefore, the rotating plate 204 has a torsional clamping force on the other rod 204c, making it difficult for the plug plate 203a to move axially.

[0055] The present invention facilitates installation and replacement of the rubber roller 202 and has the advantage that, even if the plug plate 203a moves outward a little, the rubber roller 202 will not fall off as long as the end of the square rod 204c is embedded in the square groove 201c, and the structure is stable.

[0056] Furthermore, if the rubber roller 202 is to be disassembled, the limiting member 203 and the rubber roller 202 can be disassembled by pulling out the screw plate 203c from the end.

[0058] It will be appreciated that in the development of any actual embodiment, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will, for those of ordinary skill having the benefit of this disclosure, be a routine undertaking of design, fabrication, and production without undue experimentation.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
