Description

Technical Field

[0001] This application relates to the field of tooling and fixture technology, and in particular to a door hinge anti-misalignment positioning tooling. Background Technology

[0002] A car door hinge is a mechanical device that connects the car door to the car body, allowing the door to rotate relative to the body and enabling its opening and closing. A car door hinge mainly consists of three parts: a body panel that connects to the car body, a door panel that connects to the door, and a pin that connects the body panel and the door panel. After assembly, car door hinges are marked with information such as the production date and specifications.

[0003] Body parts and door parts usually have special structural shapes. The traditional method is to install them by hand and then mark them by hand. Although this method is faster in terms of production and assembly efficiency, it can lead to significant differences in the marking positions on door hinges produced in the same batch. Moreover, the door hinges may shake unexpectedly during the marking process, resulting in unclear marking information. These are all shortcomings. Utility Model Content

[0004] In order to improve the problems existing in the traditional production of automotive door hinges, this application provides a door hinge anti-misalignment positioning tool.

[0005] The door hinge anti-misalignment positioning fixture provided in this application adopts the following technical solution:

[0006] A door hinge anti-misalignment positioning fixture includes a fixture table, a stand on the fixture table, a laser marking device vertically slidably mounted on the stand, the laser marking device being electrically connected to a control system, a lifting component on the stand for driving the laser marking device to slide vertically, a first positioning component and a second positioning component on the fixture table, the first positioning component being used for positioning and fixing body parts, and the second positioning component being used for positioning and fixing door parts.

[0007] By adopting the above technical solution, the first positioning component fixes the body parts, the second positioning component fixes the door parts, and then the workers use pins to assemble and connect the body parts and door parts together to form a door hinge. After that, the lifting component drives the laser marking device to slide vertically downwards, and finally the laser marking device marks the assembled door hinge. In this way, the marked information is in the same position in the same batch of door hinges, and the marked information is clearer.

[0008] Optionally, the lifting component includes a lifting screw rotatably mounted on the upright frame, a vertical plate is provided on the tooling table, a mounting seat is vertically slidably mounted on the vertical plate, the laser marking device is mounted on the mounting seat, the mounting seat is threadedly connected to the lifting screw, and a handle is provided on the lifting screw.

[0009] By adopting the above technical solution, after the body parts and door parts are assembled to form a door hinge, the worker rotates the handle in the forward direction. The handle drives the lifting screw to rotate. Under the restriction of the vertical plate, the rotating lifting screw drives the laser marking device to descend through the mounting seat. The laser marking device continuously approaches the door hinge, thereby facilitating the laser marking device to mark on the door hinge.

[0010] Optionally, the first positioning component includes a left support plate, a shaft support plate, and a first clamping member disposed on the tooling table. A left support column is detachably disposed on the left support plate, and a shaft support column is detachably disposed on the shaft support plate. The body part is placed on the top of the left support column and the shaft support column. A first positioning pin is disposed on the left support plate. The first positioning pin is used to insert into the body part. The first clamping member is used to press the body part firmly against the top of the left support column and the top of the shaft support column.

[0011] By adopting the above technical solution, when the body part is placed on top of the left support column and the axle support column and the first positioning pin is inserted into the body part, the first clamping member presses the body part firmly on top of the left support column and the axle support column, thereby completing the positioning and fixing of the body part.

[0012] Optionally, a left top pressure bar is rotatably mounted on the first clamping member. The left top pressure bar is located above the left support column. A first cylinder is hinged between the left top pressure bar and the left support plate. A rotary cylinder is mounted on the shaft support plate. A shaft pressure bar is mounted on the piston rod of the rotary cylinder. The shaft pressure bar is located directly above the shaft support column. Both the first cylinder and the rotary cylinder are electrically connected to the control system.

[0013] By adopting the above technical solution, the control system starts the first cylinder and the rotary cylinder. The piston rod of the first cylinder extends and pushes the left top pressure bar to rotate. The rotating left top pressure bar will approach and eventually press against the upper surface of the body part. Meanwhile, the piston rod of the rotary cylinder will drive the shaft pressure bar to rotate and eventually press against the upper surface of the body part, thereby completing the positioning and fixing of the body part.

[0014] Optionally, the second positioning component includes a center support plate, a right support plate, and a second clamping member. The center support plate is detachably provided with a second positioning pin, a center support column, and a side stop column. The second positioning pin is used to insert into the door component. The right support plate is provided with a right support column and a right stop column. The door component is placed on the top of the center support column and the top of the right support column. The side stop column abuts against one side of the door component, and the right stop column abuts against the other side of the door component. The second clamping member is used to press the door component firmly against the top of the center support column and the top of the right support column.

[0015] By adopting the above technical solution, the worker places the door component on the top of the center support column and the right support column and inserts the second positioning pin into the door component. At the same time, the side support column and the right side support column abut against the side of the door component. Then, the second clamping member presses the door component firmly against the top of the center support column and the top of the right support column, thereby completing the positioning of the door component.

[0016] Optionally, the second clamping member includes a center pressure bar rotatably mounted on the center support plate, the center pressure bar being located above the door component, a second cylinder being hinged between the center pressure bar and the center support plate, a right pressure bar rotatably mounted on the right support plate, the right pressure bar being located above the door component, a third cylinder being hinged between the right pressure bar and the right support plate, and both the second cylinder and the third cylinder being electrically connected to the control system.

[0017] By adopting the above technical solution, the control system starts the second and third cylinders. The piston rod of the second cylinder extends and pushes the middle pressure bar to rotate and press against the upper surface of the door component. At the same time, the piston rod of the third cylinder extends and pushes the right pressure bar to rotate and press against the upper surface of the door component, thereby completing the positioning and fixing of the door component.

[0018] Optionally, a support column is vertically slidably arranged on the right support plate, and a support cylinder electrically connected to the control system is arranged on the right support plate. The support column is arranged on the piston rod of the support cylinder and is used to abut against the bottom of the door component.

[0019] By adopting the above technical solution, the control system starts the support cylinder, the piston rod of the support cylinder extends, and the piston rod of the support cylinder drives the support column to rise and abut against the bottom of the door component, thereby reducing the possibility that the middle of the door component may be dented, resulting in unclear coding.

[0020] Optionally, both the left and right support plates are equipped with pressure sensors electrically connected to the control system.

[0021] By adopting the above technical solution, workers can easily understand whether the body parts and door parts are placed in place and whether they are pressed tightly.

[0022] Optionally, the tooling table is provided with a hollow protective shell, the bottom of the protective shell and the side facing the stand are open, and the laser marking device is located inside the protective shell.

[0023] By adopting the above technical solution, the protective shell protects the laser marking device and reduces the possibility of accidental damage to the laser marking device by body parts and door parts.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The first positioning component fixes the body parts, and the second positioning component fixes the door parts. Then, the worker uses a pin to assemble and connect the body parts and door parts together to form a door hinge. After that, the lifting component drives the laser marking device to slide vertically downward. Finally, the laser marking device marks the assembled door hinge, so that the marked information is in the same position in the same batch of door hinges, and at the same time, the marked information is clearer.

[0026] 2. After the body parts and door parts are assembled to form the door hinge, the worker turns the handle forward. The handle drives the lifting screw to rotate. Under the restriction of the vertical plate, the rotating lifting screw drives the laser marking device to descend through the mounting base. The laser marking device continuously approaches the door hinge, thus facilitating the laser marking device to mark on the door hinge.

[0027] 3. The control system activates the support cylinder, the piston rod of the support cylinder extends, and the piston rod drives the support column to rise and abut against the bottom of the door component, thereby reducing the possibility that the middle of the door component may be dented, resulting in unclear coding.

[0040] After the body part is placed on top of the left support column 54 and the axle support column 55, the first positioning pin 56 is inserted into the body part. Then, the control system starts the first cylinder 532 and the rotary cylinder 533. The piston rod of the first cylinder 532 extends and pushes the left top pressure bar 531 to rotate. The rotating left top pressure bar 531 will approach and eventually press against the upper surface of the body part. Meanwhile, the piston rod of the rotary cylinder 533 will drive the axle pressure bar 534 to rotate and eventually press against the upper surface of the body part, thus completing the positioning and fixing of the body part.

[0042] Reference Figure 1 , Figure 2 and Figure 3The second positioning pin 64 is used to insert into the door component. The right support plate 62 is bolted with the right support column 67 and the right stop column 68. The door component is placed on the top of the middle support column 65 and the top of the right support column 67. The stop column 66 abuts against one side of the door component, and the right stop column 68 abuts against the other side of the door component.

[0044] Reference Figure 1 , Figure 2 and Figure 3 A support column 7 is vertically slidably arranged on the right support plate 62. A support cylinder 8 electrically connected to the control system is bolted to the right support plate 62. The support column 7 is bolted to the piston rod of the support cylinder 8. The support column 7 is used to abut the bottom of the door component. Pressure sensors 9 electrically connected to the control system are bolted to both the middle support column 65 and the right support plate 62.

[0045] The worker places the door component on top of the center support column 65 and the right support column 67. At this time, the second positioning pin 64 is inserted into the door component, and the side support column 66 and the right side support column 68 are both abutting against the side of the door component. Then, the control system activates the second cylinder 632, the third cylinder 634 and the support cylinder 8. The piston rod of the second cylinder 632 extends and pushes the center pressure bar 631 to rotate and press it against the upper surface of the door component.

[0046] At the same time, the piston rod of the third cylinder 634 extends, pushes the right pressure strip 633 to rotate and press against the upper surface of the door component, the piston rod of the support cylinder 8 extends, and the piston rod of the support cylinder 8 drives the support column 7 to rise and abut against the bottom of the door component, thereby completing the positioning and fixing of the door component.

[0047] Next, the workers use pins to assemble and connect the body parts and door parts together to form a door hinge. Then, the workers turn the handle 44 forward, which drives the lifting screw 41 to rotate. Under the restriction of the vertical plate 42, the rotating lifting screw 41 drives the laser marking device 3 to descend through the mounting base 43. The laser marking device 3 continuously approaches the door hinge. Finally, the laser marking device 3 marks the door hinge to complete the assembly and production of the door hinge.

Then, the control system starts the first cylinder 532 and the rotary cylinder 533. The piston rod of the first cylinder 532 extends and pushes the left top pressure bar 531 to rotate. The rotating left top pressure bar 531 will approach and finally press against the upper surface of the body part.

At this time, the second positioning pin 64 is inserted into the door component, and the side support column 66 and the right side support column 68 are both abutting against the side of the door component. Then, the control system activates the second cylinder 632, the third cylinder 634 and the support cylinder 8. The piston rod of the second cylinder 632 extends and pushes the center pressure bar 631 to rotate and press it against the upper surface of the door component.

[0050] At the same time, the piston rod of the third cylinder 634 extends, pushes the right pressure strip 633 to rotate and press against the upper surface of the door component, the piston rod of the support cylinder 8 extends, and the piston rod of the support cylinder 8 drives the support column 7 to rise and abut against the bottom of the door component, thereby completing the positioning and fixing of the door component.

[0051] Next, the workers use pins to assemble and connect the body parts and door parts together to form a door hinge. Then, the workers turn the handle 44 forward, which drives the lifting screw 41 to rotate. Under the restriction of the vertical plate 42, the rotating lifting screw 41 drives the laser marking device 3 to descend through the mounting base 43. The laser marking device 3 continuously approaches the door hinge. Finally, the laser marking device 3 marks the door hinge to complete the assembly and production of the door hinge.
