Description

Technical Field

[0001] The utility model relates to the technical field of production and assembly equipment, in particular to an assembly workstation for a fuel tank cover component. Background Art

[0002] See also Figures 1 to 3 The fuel tank cover assembly includes a tank cover body 12, a tank cover body 11 and a spring 13. The tank cover body 11 can be rotatably covered on the first open end 121 of the tank cover body 12. The first torsion arm 131 of the spring 13 is hooked on the curved hinge end 111 of the tank cover body 11. The second torsion arm 132 of the spring 13 is pressed against the curved hinge cavity 123 of the tank cover body 12. The tank cover body 11 and the tank cover body 12 are both injection molded parts. The two side surfaces of the curved hinge end 111 of the tank cover body 11 are respectively protruding with a rotating shaft 112. The two side surfaces of the curved hinge cavity 123 of the tank cover body 12 are respectively provided with grooves 124. One rotating shaft 112 is rotatably located in one groove 124.

[0003] When the fuel tank cover assembly is produced and assembled, the first torsion arm 131 of the spring 13 is first hooked on the curved hinged end 111 of the tank cover body 11, and then the curved hinged end 111 of the tank cover body 11 together with the spring 13 is inserted into the curved hinged cavity 123 of the tank cover body 12, and then the pressing head is controlled by the pressing equipment to press downward on the curved hinged end 111 of the tank cover body 11 in the vertical direction, so that the two rotating shafts 112 on the curved hinged end 111 of the tank cover body 11 are respectively pressed into the two grooves 124 in the curved hinged cavity 123 of the tank cover body 12. However, the existing press-fitting equipment controls the pressing head to force the curved hinged end 111 of the box cover body 11 to move downward in the vertical direction so as to be press-fitted into the curved hinged cavity 123 of the box cover body 12. Since the curved hinged end 111 of the box cover body 11 and the curved hinged cavity 123 of the box cover body 12 are both arranged in a curved arc shape, and the two grooves 124 are located at the bottom of the curved hinged cavity 123, when the pressing head forces the curved hinged end 111 of the box cover body 11 to move downward in the vertical direction, the two rotating shafts 112 on the curved hinged end 111 of the box cover body 11 and the two rotating shafts 112 on the curved hinged cavity 123 of the box cover body 12 are pressed together. The side interference moves downward in the vertical direction so that the two rotating shafts 112 on the curved hinged end 111 of the tank cover body 11 are simultaneously pressed into the groove 124 located at the bottom of the curved hinged cavity 123. The two rotating shafts 112 interfere with the two side surfaces of the curved hinged cavity 123 of the tank cover body 12 in the vertical direction and move downward at the same time. Under the action of the elastic force of the spring 13, the rotating shafts 112 and the grooves 124 are easily misaligned, so that during the press-fitting process, the rotating shafts 112 are easily squeezed and burst the side surfaces of the curved hinged cavity 123 that interfere with them, resulting in a decrease in the production and assembly yield of the fuel tank cover assembly. Summary of the invention

[0004] The main purpose of the utility model is to provide a fuel tank cover assembly assembly workstation with high production and assembly yield, good production and assembly quality, high automation and high production and assembly efficiency.

[0005] To achieve the above-mentioned main purpose, the utility model provides a fuel tank cap assembly assembly workstation, including a fixed jig, a pressing mechanism and a pushing mechanism. The fixed jig is used to place the tank cap body and the tank cover body of the fuel tank cap assembly. The first torsion arm of the spring of the fuel tank cap assembly is hooked on the curved hinged end of the tank cap body, and the second torsion arm of the spring is pressed against the curved hinged cavity of the tank cover body. The pressing mechanism includes a pressing head and a clamping control mechanism. The clamping control mechanism can control the pressure head to move in the vertical direction. The pressure head can be pressed against the curved hinged end so that the curved hinged end is pressed into the curved hinged cavity, and the two rotating shafts on the curved hinged end are respectively pressed into the two grooves of the curved hinged cavity. The pushing mechanism includes a pushing plate, a pushing wheel and a moving control mechanism. The pushing wheel can be rotatably supported on the pushing plate around the vertical direction. The moving control mechanism can control the pushing plate to move in the horizontal direction. The outer peripheral wall of the pushing wheel can be pushed against the outer hanging end of the tank cap body away from the curved hinged end to force the outer hanging end to move in the horizontal direction.

[0006] It can be seen from the above scheme that when the fuel tank cap assembly assembly workstation of the utility model produces and assembles the fuel tank cap assembly, the curved hinge cavity of the tank cover body is first placed on the fixing fixture, and then the curved hinge end of the tank cover body hooked with the first torsion arm of the spring is pressed into the curved hinge cavity of the tank cover body, so that a rotating shaft on the curved hinge end of the tank cover body is pressed into a groove of the curved hinge cavity of the tank cover body, and at this time, the other rotating shaft on the curved hinge end of the tank cover body interferes with the side of the curved hinge cavity, and then the pressing control mechanism controls the pressure head to move downward in the vertical direction. The movement presses against the curved hinged end of the box cover body, and the pressure head continues to move downward in the vertical direction to force the other rotating shaft on the curved hinged end of the box cover body to move to the bottom of the curved hinged cavity. The movement control mechanism controls the pushing plate to drive the pushing wheel to move in the horizontal direction, so that the outer peripheral wall of the pushing wheel presses against the outer hanging end of the box cover body away from its curved hinged end to force the outer hanging end of the box cover body to move in the horizontal direction, thereby making the other rotating shaft on the curved hinged end of the box cover body move into another groove of the curved hinged cavity of the box cover body. Compared with the existing press-fitting equipment, which forces the two rotating shafts to interfere with the two side surfaces of the curved hinge cavity of the tank cover body in the vertical direction and move downward at the same time, the elastic force of the spring easily causes the rotating shaft and the groove to be offset, so that the rotating shaft of the existing press-fitting equipment is easy to squeeze and burst the side surface of the curved hinge cavity that interferes with it during the press-fitting process, resulting in a decrease in the production and assembly yield of the fuel tank cover assembly. In the utility model, when the fuel tank cover assembly assembly workstation is producing and assembling the fuel tank cover assembly, only one rotating shaft interferes and press-fits with the side surface of the curved hinge cavity. When the rotating shaft is pressed to the bottom of the curved hinge cavity, the movement control mechanism controls the pushing plate to drive the pushing wheel to move in the horizontal direction, so that the outer peripheral wall of the pushing wheel pushes against the outer hanging end of the tank cover body away from its curved hinge end, so as to force the outer hanging end of the tank cover body to move in the horizontal direction, so that the rotating shaft moves into the groove, thereby avoiding the side surface of the curved hinge cavity from being squeezed and burst, so that the production and assembly quality is good, the production and assembly yield is improved, and the production and assembly automation degree is high, thereby improving the production and assembly efficiency.

[0030] See also Figures 4 to 13The present embodiment discloses a fuel tank cap assembly workstation 20, comprising a fixing fixture 21, a pressing mechanism 22 and a pushing mechanism 23. The fixing fixture 21 is used to place the tank cap body 11 and the tank cover body 12 of the fuel tank cap assembly. The first torsion arm 131 of the spring 13 of the fuel tank cap assembly is hooked on the curved hinge end 111 of the tank cap body 11, and the second torsion arm 132 of the spring 13 is pressed against the curved hinge cavity 123 of the tank cover body 12. Among them, the pressing mechanism 22 of this embodiment includes a pressing head 223 and a clamping control mechanism. The clamping control mechanism can control the pressing head 223 to move in the vertical direction. The pressing head 223 can be pressed against the curved hinged end 111 of the box cover body 11 so that the curved hinged end 111 of the box cover body 11 is pressed into the curved hinged cavity 123 of the box cover body 12, and the two rotating shafts 112 on the curved hinged end 111 of the box cover body 11 are respectively pressed into the two grooves 124 of the curved hinged cavity 123 of the box cover body 12. In addition, the pushing mechanism 23 of this embodiment includes a pushing plate 232, a pushing wheel 234 and a movement control mechanism. The pushing wheel 234 can be rotatably supported on the pushing plate 232 around the vertical direction. The movement control mechanism can control the pushing plate 232 to move in the horizontal direction. The outer peripheral wall of the pushing wheel 234 can be pushed against the outer hanging end 113 of the box cover body 11 away from its bent hinge end 111 to force the outer hanging end 113 of the box cover body 11 to move in the horizontal direction.

[0031] When the tank cap assembly assembly workstation 20 of the present embodiment produces and assembles the tank cap assembly, the bent hinge cavity 123 of the tank cover body 12 is first placed on the fixing fixture 21, and then the bent hinge end 111 of the tank cover body 11 hooked with the first torsion arm 131 of the spring 13 is pressed into the bent hinge cavity 123 of the tank cover body 12, so that a rotating shaft 112 on the bent hinge end 111 of the tank cover body 11 is pressed into a groove 124 of the bent hinge cavity 123 of the tank cover body 12. At this time, the other rotating shaft 112 on the bent hinge end 111 of the tank cover body 11 is pressed into the bent hinge cavity 123 of the tank cover body 12. The side interference of the cavity 123, then the clamping control mechanism controls the pressure head 223 to move downward in the vertical direction to press on the curved hinge end 111 of the box cover body 11, and as the pressure head 223 continues to move downward in the vertical direction to force the other rotating shaft 112 on the curved hinge end 111 of the box cover body 11 to move to the bottom of the curved hinge cavity 123, the movement control mechanism controls the pushing plate 232 to drive the pushing wheel 234 to move in the horizontal direction, so that the outer peripheral wall of the pushing wheel 234 presses on the outer hanging end 113 of the box cover body 11 away from its curved hinge end 111, as shown in FIG. Fig. 9 As shown, the outer hanging end 113 of the box cover body 11 is forced to move in the horizontal direction, so that the other rotating shaft 112 on the curved hinge end 111 of the box cover body 11 moves into the other groove 124 of the curved hinge cavity 123 of the box cover body 12, as shown in FIG. Fig.10Compared with the existing press-fitting equipment that forces the two rotating shafts 112 to interfere with the two side surfaces of the curved hinge cavity 123 of the tank cover body 12 in the vertical direction and move downward at the same time, the elastic force of the spring 13 easily causes the rotating shaft 112 and the groove 124 to be offset, so that the rotating shaft 112 of the existing press-fitting equipment is easy to squeeze and burst the side surface of the curved hinge cavity 123 that interferes with it during the press-fitting process, resulting in a decrease in the production and assembly yield of the fuel tank cover assembly. In the fuel tank cover assembly assembly workstation 20 of this embodiment, only one rotating shaft 112 interferes with the side surface of the curved hinge cavity 123 during the production and assembly of the fuel tank cover assembly. When the rotating shaft 112 is pressed, the rotating shaft 112 is pressed. When 112 is pressed to the bottom of the curved hinge cavity 123, the movement control mechanism controls the push plate 232 to drive the push wheel 234 to move in the horizontal direction, so that the outer peripheral wall of the push wheel 234 pushes on the outer hanging end 113 of the box cover body 11 away from its curved hinge end 111, so as to force the outer hanging end 113 of the box cover body 11 to move in the horizontal direction, so that the rotating shaft 112 moves into the groove 124, thereby avoiding the side of the curved hinge cavity 123 from being squeezed and exploded, so that the production and assembly quality is good, the production and assembly yield rate is improved, and the production and assembly automation degree is high, thereby improving the production and assembly efficiency.

[0032] Combination Figures 5 to 7In this embodiment, a fuel tank cap assembly workstation 20 also includes an anti-foolproof detection mechanism 24, which includes a detection fixture 241 and a first sensor 247.

The bottom end surface of the first positioning groove 242 is provided with a second positioning groove 243. The second torsion arm 132 of the spring 13 can be located in the second positioning groove 243. The first sensor 247 is arranged on the groove side of the second positioning groove 243 and is used to detect the second torsion arm 132. Therefore, before the box cover body 11 with the spring 13 hooked thereto is produced and assembled, the box cover body 11 with the spring 13 hooked thereto is first placed on the detection jig 241 of the fool-proof detection mechanism 24, so that the bent hinged end 111 of the box cover body 11 is placed in the first positioning groove 242 of the detection jig 241, and a torsion arm of the spring 13 is located in the second positioning groove 243 of the detection jig 241. When the first sensor 247 detects the second torsion arm 132 of the spring 13, it indicates that the first torsion arm 131 of the spring 13 is hooked on the bent hinged end 111 of the box cover body 11, which indicates that the spring 13 is correctly installed on the bent hinged end 111 of the box cover body 11. If the spring 13 is assembled incorrectly on the curved hinge end 111 of the tank cover body 11, that is, the second torsion arm 132 of the spring 13 is hooked on the curved hinge end 111 of the tank cover body 11, so that the first torsion arm 131 of the spring 13 is located in the second positioning groove 243, the first sensor 247 cannot detect and identify the second torsion arm 132 of the spring 13, which indicates that the spring 13 is incorrectly installed on the curved hinge end 111 of the tank cover body 11. The tank cover assembly assembly workstation 20 of this embodiment detects whether the spring 13 is correctly installed on the curved hinge end 111 of the tank cover body 11 through the foolproof detection mechanism 24 to ensure the production and assembly quality of the tank cover assembly.

Specifically, a cantilever 224 is connected to the side of the pressing head 223 of this embodiment, and the cantilever 224 extends in the horizontal direction. The end of the cantilever 224 away from the pressing head 223 is connected to the piston rod of the pressing cylinder 222. By setting the cantilever 224, the pressing work area of ​​the fuel tank cap assembly workstation 20 will not be too compact, which facilitates the placement of the tank cap body 11 and the tank cover body 12 on the fixed fixture 21, and the overall structure of the workstation 20 is more reasonable, which is more conducive to improving the production and assembly efficiency.

[0035] Combination Fig.11 In this embodiment, the outer peripheral wall of the push wheel 234 of the push mechanism 23 is sleeved with a silicone sleeve 235. The outer peripheral wall of the silicone sleeve 235 can be pushed against the outer hanging end 113 of the box cover body 11 to force the outer hanging end 113 of the box cover body 11 to move in the horizontal direction. Since the silicone sleeve 235 has a certain elastic deformation ability, it can avoid causing damage to the outer hanging end 113 of the box cover body 11 when pushing the outer hanging end 113 of the box cover body 11, thereby improving the production and assembly quality. Specifically, in this embodiment, the push plate 232 is provided with a shaft body 233 extending in the vertical direction, and the push wheel 234 can be sleeved on the shaft body 233 rotatably around the vertical direction. Furthermore, the mobile control mechanism of this embodiment is a mobile cylinder 231, and the piston rod of the mobile cylinder 231 extends in the horizontal direction and is connected to the push plate 232.
