Description
Technical Field
[0001] This utility model belongs to the field of automotive painting tooling and auxiliary tools, and specifically relates to a side-opening car tailgate support tooling. Background Technology
[0002] Currently, when the car body passes through the ISS station on the coating line after electrophoresis, the rear door needs to be supported and secured to prevent collisions with the robot during operation. Existing SUV side-opening car rear doors use conventional support rods to support the side-opening doors. Due to the change in the direction of force on the side-opening door, the support rods are prone to wobbling and falling during the car body's transport on the roller bed, causing equipment collisions and severely impacting production. Furthermore, damaged doors require repair, resulting in wasted labor costs, and scrapped doors and equipment cause direct property damage. Equipment maintenance is also necessary, further delaying production. To solve this problem, robust auxiliary tools need to be developed to meet the requirements. Utility Model Content

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0037] Example 1,
[0038] like Figure 1 As shown, Figure 1 A schematic diagram of the overall structure in Embodiment 1 of this utility model is shown; see reference. Figure 1 A tooling for a side-opening car tailgate support rod includes a first connector 2, a connecting rod body 3, a first structural hook 4, and a first sliding rod 5. The first sliding rod 5 is slidably mounted on one end of the connecting rod body 3, and a connecting part is provided at the other end for connecting to the mounting hole of the rear anti-collision beam of the vehicle body. The first connector 2 is provided at the end of the first sliding rod 5 away from the connecting rod body 3. The first structural hook 4 is provided at the end of the first connector 2 away from the first sliding rod 5 (please refer to...). Figure 3 The first self-locking pin 1 is installed in the fourth circular hole 302 of the connecting rod body 3, and the first self-locking pin 1 is perpendicular to the axis of the connecting rod body 3; the fourth circular hole 302 is located at the end of the connecting rod body 3 away from the first sliding rod 5, and the first self-locking pin 1 can extend and retract. Figure 1 The diagram shows the first self-locking pin 1 extending. When the first self-locking pin 1 is subjected to external pressure, it can retract into the connecting rod body 3, thereby facilitating the insertion of the connecting rod body 3 into the mounting hole of the rear anti-collision beam of the vehicle body.
[0039] Specifically, by connecting the connecting part to the mounting hole of the rear anti-collision beam of the vehicle body, and then adjusting the relative position of the first sliding rod 5 and the connecting rod body 3, the length of this tooling can be adjusted to adapt to the side-opening rear doors of different vehicle models; the first structural hook 4 is V-shaped, and inner grooves are provided on both outer sides of the opening of the first structural hook 4. The inner grooves are used to lock into the mounting hole of the rear door of the vehicle. By manually pinching the first structural hook 4, the heads of the first structural hook 4 retract towards each other, and then the heads of the first structural hook 4 are inserted into the hole of the side-opening rear door of the car. When the hand is released, the first structural hook 4 is locked into the hole of the side-opening rear door of the car.
[0040] In the above embodiment, another optional implementation is that there are two fourth circular holes 302, which are arranged sequentially along the axial direction of the connecting rod body 3. A first self-locking pin 1 and a second self-locking pin 11 are respectively provided in the two fourth circular holes 302. The first self-locking pin 1 and the second self-locking pin 11 are engaged with the iron plate of the rear anti-collision beam mounting hole on both sides of the vehicle body, thereby fixing the connecting rod body 3 and preventing it from moving. The length of the second self-locking pin 11 closer to the first sliding rod 5 is less than the length of the first self-locking pin 1 farther from the first sliding rod 5 (e.g., ...). Figure 2 (As shown). The first self-locking pin 1 near the first sliding rod 5 needs to be inserted into the mounting hole of the rear anti-collision beam of the vehicle body. In order to prevent the first sliding rod 5 from being pulled out of the mounting hole of the rear anti-collision beam of the vehicle body when the rear tailgate of the car is opened again, the first self-locking pin 1 near the first sliding rod 5 is set to be longer, and the second self-locking pin 11 far away from the first sliding rod 5 is shorter. In order to facilitate the insertion of the longer first self-locking pin 1 and the connecting rod body 3 into the mounting hole of the rear anti-collision beam of the vehicle body.
[0041] Preferably, the first self-locking pin 1 and the second self-locking pin 11 respectively include a first pin 101, a spring 102 and a pin cap 103 (see reference). Figure 5 The first pin 101 is fixedly installed in the fourth circular hole 302, and a spring 102 is fitted onto the first pin 101. The pin cap 103 is slidably installed on the first pin 101 and in the fourth circular hole 302. One end of the spring 102 abuts against the first pin 101, and the other end abuts against the pin cap 103. Specifically, the spring 102 positions the pin cap 103 at the highest point of the first pin 101, thereby allowing the pin cap 103 to engage with the mounting hole of the rear anti-collision beam of the vehicle body. At the same time, since both ends of the spring 102 are connected to the first pin 101 and the pin cap 103 respectively, the pin cap 103 is prevented from detaching from the first pin 101.
[0042] In use, a hemispherical top is provided on the top of the pin cap 103. The top of the pin cap 103 contacts the mounting hole of the rear bumper beam, compressing the pin cap 103 and causing it to retract against the elastic force of the spring 102. This allows the long pin cap 103 to engage with the mounting hole of the rear bumper beam. Simultaneously, the pin cap 103 of the second self-locking pin 11 on the outer side of the vehicle body prevents the connecting rod body 3 from further extending into the mounting hole of the rear bumper beam. When not in use, the angle of the connecting rod body 3 can be manually adjusted (e.g., ...). Figure 8 (a to 8b) Then adjust the angle of the first self-locking pin 1 so that the pin cap 103 of the first self-locking pin 1 can contact the mounting hole edge of the rear anti-collision beam of the vehicle body and be compressed, thereby facilitating the removal of the first self-locking pin 1 (e.g. Figure 8 b to 8c).
[0043] Please refer to Figure 4 , Figure 4A schematic diagram of the limiting pin 6 in Embodiment 1 of this utility model is shown. The tooling also includes the limiting pin 6, which includes a second pin 601 and a cotter pin 602. The second pin 601 is installed through the first circular hole 301 and the second circular hole 501, and the cotter pin 602 is installed in the fifth circular hole 603 of the limiting pin 6 to prevent the limiting pin 6 from disengaging from the first circular hole 301 and the second circular hole 501. As needed, the positions of the connecting rod body 3 and the first sliding rod 5 are adjusted to align the corresponding first circular hole 301 and the second circular hole 501. Then, the fixing is completed by inserting the second pin 601 into the first circular hole 301 and the second circular hole 501 and installing the cotter pin 602 into the fifth circular hole 603 of the second pin 601.
[0044] A limiting pin 6 is installed in the first circular hole 301 of the connecting rod body 3 and the second circular hole 501 of the first sliding rod 5. The limiting pin 6 limits the length of the connecting rod body 3 and the first sliding rod 5 that the first sliding rod 5 slides out of the connecting rod body 3. There are several first circular holes 301, equidistantly arranged along the axis of the connecting rod body 3. The second circular hole 501 coincides with different first circular holes 301, allowing the limiting pin 6 to be installed, thus adjusting the relative position of the connecting rod body 3 and the first sliding rod 5. The first circular holes 301 and second circular holes 501 have the same diameter, facilitating the installation of the limiting pin 6.
[0045] Example 2,
[0046] like Figure 6 As shown, Figure 6 A schematic diagram of the overall structure in Embodiment 2 of this utility model is shown. (See reference) Figure 6 The connecting part includes a second connector 21, a second structural hook 41, and a second sliding rod 51. The second sliding rod 51 is slidably installed at the end of the connecting rod body 3 away from the first sliding rod 5, and the second connector 21 is provided at the end of the second sliding rod 51 away from the connecting rod body 3. The second structural hook 41 is provided at the end of the second connector 21 away from the second sliding rod 51. The second structural hook 41 is V-shaped, and inner grooves are provided on both outer sides of the opening of the second structural hook 41. The inner grooves are used to lock into the mounting hole of the rear anti-collision beam of the vehicle body. By manually pinching the second structural hook 41, the head of the second structural hook 41 is retracted, and then the head of the second structural hook 41 is inserted into the mounting hole of the rear anti-collision beam of the vehicle body. Releasing the hand allows the second structural hook 41 to lock into the mounting hole of the rear anti-collision beam of the vehicle body.
[0047] In the above embodiments, another optional implementation is that the limiting pin 6 is installed in the first circular hole 301 of the connecting rod body 3 and the third circular hole 511 of the second sliding rod 51 (please refer to...). Figure 7 ).
[0048] Working principle of this utility model:
[0049] In use, this utility model selects a first self-locking pin 1 as the connecting part, adjusts the relative positions of the first sliding rod 5 and the connecting rod body 3 to adjust the length of the tooling, and aligns the corresponding first round hole 301 and second round hole 501. Then, the second pin 601 is inserted into the first round hole 301 and second round hole 501, and the cotter pin 602 is installed into the fifth round hole 603 of the second pin 601 to complete the fixing. The first structural hook 4 is manually pinched to retract its head, then inserted into the hole of the car's side-opening rear tailgate. Releasing the hand allows the first structural hook 4 to engage with the hole in the car's side-opening rear tailgate. The first self-locking pin 1 is retractable, such as... Figure 4 The diagram shows the first self-locking pin 1 extending. When the first self-locking pin 1 is subjected to external pressure, it can retract into the connecting rod body 3, thereby facilitating the insertion of the connecting rod body 3 into the mounting hole of the rear anti-collision beam of the vehicle body to complete the installation of the tooling.
[0050] When using this utility model, the connecting part is selected as the second connector 21, the second structural hook 41, and the second sliding rod 51 as needed. By adjusting the relative position of the second sliding rod 51 and the connecting rod body 3, the length of this tooling can be adjusted, and the corresponding fourth round hole 302 and third round hole 511 can be aligned. Then, the second pin 601 is inserted into the fourth round hole 302 and the third round hole 511, and the cotter pin 602 is installed in the fifth round hole 603 of the second pin 601 to complete the fixation. Alternatively, the length of this tooling can be adjusted by adjusting the relative position of the first sliding rod 5 and the connecting rod body 3, and the corresponding first round hole 301 and second round hole 501 can be aligned. Then, the second pin 601 is inserted into the first round hole 301 and the second round hole 501, and the cotter pin 602 is installed in the fifth round hole 603 of the second pin 601 to complete the fixation.
[0051] By manually pinching the first structural hook 4 to retract its head, the head of the first structural hook 4 is inserted into the hole of the car's side-opening rear tailgate. Then, the hand is released, allowing the first structural hook 4 to be locked into the hole of the car's side-opening rear tailgate.
