Description

Technical Field

[0001] The invention relates to the technical field of automobile parts production and processing, and in particular to a production device for automobile steel hinges and steel hinge locking screws. Background Art

[0002] The door hinge has two basic functions: one is to connect the door and the body and ensure and maintain the position of the door relative to the body, the other is to ensure and facilitate the opening and closing of the door.

[0003] The first basic function of the door hinge is to connect the door and the body and to ensure and maintain the position of the door relative to the body. This requires that the mounting surfaces between the door hinge, the door and the body must be flat. If the door hinge is connected by bolts, the relative dimensions between the bolt mounting holes of the body and door parts must be consistent and stable.

[0004] The most important factor affecting the stability of the connection between the door hinge and the car lies in the production process of the door hinge and the steel hinge locking screws. In the existing technology, the production process of the door hinge and the steel hinge locking screws has the following problems: 1. The production of door hinges usually uses a cutting machine to cut a metal block into several door hinges. When the cutting machine acts on the metal block, it is also necessary to use a limiting mechanism to squeeze and fix the metal block to prevent deviation. When pushing the metal block forward to cut out the next door hinge, the limiting mechanism needs to be away from the door hinge. At the moment of unloading the limiting mechanism, the metal block will be brought out a little by the limiting mechanism, and then there will be a slight movement, resulting in the size of the door hinge. 1. A small deviation may cause a deviation in the relative size of the door hinge and the car body, which may cause abnormal noise during driving and affect the high-end feel of the vehicle; 2. A through hole needs to be opened on the door hinge for the insertion of the steel hinge locking screw. Due to the moment of force unloading of the limit mechanism, the metal block will be brought out a little by the limit mechanism, and then there will be a slight movement, resulting in a relative size deviation between the size of the door hinge and the bolt mounting hole, which may also cause abnormal noise during driving; 3. The door hinge, bolt mounting holes and steel hinge locking screws are usually manufactured separately by at least three workstations, and the workpieces need to be transferred manually or by conveyor belt in the middle, which leads to reduced production efficiency.

[0038] See also Figures 1 to 12, shown is a production device for automobile steel hinges and steel hinge locking screws in an embodiment of the present invention, comprising a bearing seat 10, a metal block 80 slidably connected to the bearing seat 10, a cutting mechanism 30 for cutting the metal block 80, a punching mechanism 50 for punching a bolt hole 81, and a limiting mechanism 40 for squeezing the metal block 80, the bearing seat 10 comprises a first bearing portion 11 and a second bearing portion 12 arranged at intervals, a cutting gap 14 is provided between the first bearing portion 11 and the second bearing portion 12, the cutting mechanism 30 comprises a first fixed platform 31 and a cutting assembly slidably connected to the first fixed platform 31, the cutting assembly moves along the cutting gap 14 to cut the metal block 80, the limiting mechanism 40 comprises a second fixed platform 41, a first extrusion plate 44 and a second extrusion plate 45 slidably connected to the second fixed platform 41, a third extrusion plate 46 located on a side of the second extrusion plate 45 away from the first extrusion plate 44, and a third extrusion plate 46 connecting the first extrusion plate 44 and the second extrusion plate 45 The first elastic member 47 and the second elastic member 48 connecting the second extrusion plate 45 and the third extrusion plate 46, the first extrusion plate 44 is located on the side of the second extrusion plate 45 away from the bearing seat 10, the punching mechanism 50 includes a third fixed platform 51, a rotating platform 52 rotatably connected to the third fixed platform 51, and a punching assembly arranged on the rotating platform 52, the automobile steel hinge and steel hinge locking screw production device also includes a rolling mechanism 90 for manufacturing bolts, the rolling mechanism 90 includes a first fixed rolling plate 94, a second rolling plate 95 moving relative to the first rolling plate 94, and a driving assembly driving the second rolling plate 95 to reciprocate, the first rolling plate 94 and the second rolling plate 95 are opposite to each other. The side is provided with a flower head rolling structure 96, a thread rolling structure 97, and a conical rolling structure 98 from top to bottom, the flower head rolling structure 96 includes a plurality of rolling blocks 99, and the plurality of rolling blocks 99 gradually increase according to the positive movement direction of the second rolling plate 95.

[0039] It can be understood that the present invention sequentially arranges the third extrusion plate 46, the second extrusion plate 45, and the first extrusion plate 44 from the bearing seat 10 outward, and arranges the first elastic member 47 between the first extrusion plate 44 and the second extrusion plate 45, and arranges the second elastic member 48 between the second extrusion plate 45 and the third extrusion plate 46. The third extrusion plate 46 always abuts against the metal block 80, so that the second elastic member 48 always maintains an elastic state. When the pushing mechanism 20 pushes the metal block 80 to move, under the extrusion of the third extrusion plate 46, the metal block 80 will not move slightly, so as to improve the dimensional accuracy. Since the door hinge cut by the metal block 80 has There are two small grooves 82. When the cutting mechanism 30 cuts the small groove 82 of the door hinge along the cutting gap 14, the first extrusion plate 44 is controlled to move, thereby first compressing the second elastic member 48, thereby improving the limiting effect on the metal block 80. When the cutting assembly moves to the farthest distance of the small groove 82, the second elastic member 48 will no longer be compressed. When the cutting mechanism 30 cuts a complete door hinge along the cutting gap 14, the first extrusion plate 44 is controlled to move, thereby first compressing the second elastic member 48. When the second elastic member 48 is no longer compressed, the first elastic member 47 will be compressed, so that the first extrusion plate 44 and the second extrusion plate 44 are compressed. The plate 45 is close to provide a stronger extrusion force to the metal block 80, and the limiting effect is improved until the door hinge is completely cut off. When the cutting assembly retracts and the metal block 80 is pushed, it will touch the punching assembly, so that the punching assembly punches a hole in the metal block 80. Every time the metal block 80 is pushed a little, the bolt hole 81 will be deeper until the door hinge is completely cut off to punch through the bolt hole 81. Then the rotating table 52 is controlled to rotate so that the punching assembly drives the cut door hinge to rotate to the unloading station (not shown in the figure), the bolt hole 81 is removed and the steel hinge locking screw is installed, so the production of the automobile steel hinge is completed. Then, by setting the rolling mechanism 90, the steel hinge locking screw is tightened. The nail is placed between the first rolling plate 94 and the second rolling plate 95, and the second rolling plate 95 is driven by the driving component to reciprocate relative to the first rolling plate 94 to produce the steel hinge locking screw. Specifically, when the steel hinge locking screw enters between the first rolling plate 94 and the second rolling plate 95, the second rolling plate 95 drives the steel hinge locking screw to move forward, and the middle part of the steel hinge locking screw will be rolled out with a thread 122 through the thread rolling structure 97, and the lower part of the steel hinge locking screw will be rolled out with a conical bottom end 123 through the conical rolling structure 98, and the upper part of the steel hinge locking screw will be rolled out with a flower head 121 through the flower head rolling structure 96, thereby completing the production of the steel hinge locking screw.

[0040] It should be noted that the elastic force of the first elastic member 47 is greater than the elastic force of the second elastic member 48 , so that the second elastic member 48 will be compressed first.

[0041] Specifically, in this embodiment, a first linkage mechanism 60 is provided between the cutting mechanism 30 and the limiting mechanism 40, and the first linkage mechanism 60 includes a screw rod 74, a first nut 76 and a second nut 73 respectively arranged at both ends of the screw rod 74, and a first motor 75 for driving the screw rod 74 to rotate, and the screw rod 74 has a first thread 741 and a second thread 742 arranged in opposite directions, the first nut 76 is arranged at the first thread 741, and the second nut 73 is arranged at the second thread 742, the first nut 76 is connected to the cutting assembly, and the second nut 73 is connected to the first extrusion plate 44.

[0042] It can be understood that the first motor 75 drives the screw rod 74 to rotate, so that the first nut 76 and the second nut 73 move relative to each other. When the cutting assembly is cutting the metal block 80, the first extrusion plate 44 will also move toward the metal block 80 to extrude the metal block 80. The deeper the cutting assembly moves, the deeper the first extrusion plate 44 is extruded, so as to realize adaptive adjustment of the limiting effect.

[0043] Furthermore, a second linkage mechanism 70 is provided between the punching mechanism 50 and the limiting mechanism 40, and the second linkage mechanism 70 includes a first rotating shaft 56 fixedly connected to the rotating table 52, a second rotating shaft 54 ​​provided below the third fixed table 51, a third rotating shaft 55 connected to the second rotating shaft 54, a missing gear 58 sleeved on the second rotating shaft 54, a circular gear 57 sleeved on the first rotating shaft 56, a fourth rotating shaft 72 rotatably connected to the first extrusion plate 44, and a connecting rod 71 whose two ends are respectively hinged to the third rotating shaft 55 and the fourth rotating shaft 72.

[0044] It can be understood that when the first extrusion plate 44 moves, it will drive the connecting rod 71 to move, so that the connecting rod 71 drives the third rotating shaft 55 to rotate limitedly around the second rotating shaft 54, and then drives the missing gear 58 to rotate. By adjusting the accuracy of the first linkage mechanism 60, after the cutting assembly completely cuts out a door hinge, the corresponding position of the first nut 76 corresponds to the position of the second nut 73. When the cutting assembly continues to move a certain distance toward the limiting mechanism 40, the first extrusion plate 44 continues to move, which will cause the connecting rod 71 to drive the third rotating shaft 55 to rotate around the second rotating shaft 54 ​​by a certain angle. At this time, the missing gear 58 contacts the circular gear 57, driving the first rotating shaft 56 to rotate together with the rotating table 52, and the rotating table 52 drives the punching assembly to rotate, so as to remove the cut door hinge through the unloading station and install the steel hinge locking screw. When the screw rod 74 rotates to drive the cutting assembly back to its original position, the punching assembly and the first extrusion plate 44 will also be reset.

[0045] Furthermore, the cutting assembly includes a bearing seat 35 slidably connected to the first fixed platform 31, a fifth rotating shaft 36 rotatably arranged on the bearing seat 35, a cutting wheel 37 fixedly connected to the fifth rotating shaft 36, and a second motor 34 that drives the fifth rotating shaft 36 to rotate; the first nut 76 and the bearing seat 35 are fixedly connected by a first connecting member 77, the first connecting member 77 is partially located inside the first fixed platform 31, and the first fixed platform 31 is respectively provided with a first slide groove 32 and a second slide groove 33 for the first connecting member 77 to slide; the second nut 73 and the first extrusion plate 44 are fixedly connected by a second connecting member 78, the second connecting member 78 is partially located inside the second fixed platform 41, and the second fixed platform 41 is respectively provided with a third slide groove 42 and a fourth slide groove 43 for the second connecting member 78 to slide; a slider that slides along the third slide groove 42 is provided under the second extrusion block.

[0046] It can be understood that when the first nut 76 drives the bearing seat 35 to move, the cutting wheel 37 can be driven to rotate by the second motor 34 to cut the metal block 80, and the first connecting member 77 and the second connecting member 78 are respectively located inside the first fixed platform 31 and the second fixed platform 41, wherein the upper end of the first connecting member 77 will slide along the first slide groove 32, and the side end of the first connecting member 77 will slide along the second slide groove 33, the upper end of the second connecting member 78 will slide along the third slide groove 42, and the side end of the second connecting member 78 will slide along the fourth slide groove 43, and the second extrusion block will also slide along the third slide groove 42 through the slider (not shown in the figure).

[0047] Furthermore, the drilling assembly includes a drill rod 53 disposed on the rotating platform 52 and a third motor disposed inside the rotating platform 52 , and the third motor is used to drive the drill rod 53 to rotate.

[0048] It can be understood that when the pushing mechanism 20 drives the metal block 80 to move, the drill rod 53 can be driven to rotate by the third motor to perform drilling operations on the metal block 80. Due to the limiting effect of the limiting mechanism 40, the position of the metal block 80 is more stable during drilling, thereby improving the dimensional accuracy of the bolt hole 81.

[0049] Furthermore, a groove 13 matching the shape of the metal block 80 is formed on the first bearing portion 11 and the second bearing portion 12 .

[0050] It can be understood that by providing a groove 13 that matches the shape of the metal block 80, when the pushing mechanism 20 drives the metal block 80 to move, the position stability during the movement can be improved, thereby improving the dimensional accuracy of the door hinge.

[0051] Furthermore, the automobile steel hinge and steel hinge locking screw production device also includes a conveyor belt 110 and a toggle assembly 100 arranged at the end points of the rolling mechanism 90 and the punching mechanism 50, the toggle assembly 100 includes a toggle plate 101 and a rotating motor 102 for driving the toggle plate 101 to rotate, the driving assembly includes a flywheel 91, a connecting rod 93, and a stepper motor 92 for driving the flywheel 91 to rotate, one end of the connecting rod 93 is hinged to the second rolling plate 95, and the other end of the connecting rod 93 is hinged to the non-axial part of the flywheel 91.

[0052] It can be understood that the punching mechanism 50 will transmit the steel hinge to the conveyor belt 110, and then drive the toggle plate 101 to rotate through the rotating motor 102, so as to toggle the steel hinge on the drill rod 53 onto the conveyor belt 110. At the same time, the produced steel hinge locking screws will also fall onto the conveyor belt 110. The steel hinge and the steel hinge locking screws can be simultaneously transmitted to the assembly station for assembly, thereby greatly improving the production efficiency.

[0053] In summary, the automobile steel hinge and steel hinge locking screw production device in the above embodiment of the present invention can improve the accuracy of door hinges and bolt holes during the production process and reduce abnormal noise generated during the driving of the car.
