Technical Field

[0001] The utility model relates to the technical field of automobile manufacturing, in particular to a floating positioning pin mechanism for a body-in-white adjustment line. Background Art

[0002] In the automobile manufacturing process, the adjustment of the body in white is a very critical step. The adjustment line of the body in white needs to ensure the accurate positioning of each component of the body so that the subsequent assembly work can proceed smoothly. At present, in the automobile manufacturing industry, the process of welding the body in white in the welding workshop requires multiple steps and processes. Therefore, in the final process, the various dimensions on the body in white will inevitably have a certain cumulative error, so the locating holes of the body will also have a certain amount of position deviation. This means that in the final adjustment line station, the locating pins of the fixture also need to be adjusted to adapt to the position deviation of the body locating holes, so locating pins are needed to position the body in white.

[0003] Floating locating pins are used in the adjustment line station to match the locating holes on the car body. However, due to the structural limitations of traditional floating locating pins, their floating adjustment amount is relatively small. If the above-mentioned cumulative deviation is large, there is still a problem of being unable to insert the locating holes, and it is difficult to adapt to car body parts of different sizes and shapes, resulting in inaccurate positioning. The stress on the car body may cause deformation of the car body, affecting production efficiency and product quality. Therefore, a floating locating pin mechanism for a white body adjustment line is proposed to solve the above-mentioned technical problems. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 In this embodiment, a floating positioning pin mechanism for adjusting the line of a body in white includes a base 1, an adjusting mechanism is arranged on the base 1, and an auxiliary component is arranged on the base 1.

[0024] Embodiment 1: The adjustment mechanism includes a mounting plate 2 fixedly mounted on the top of the base 1, a first electric push rod 3 fixedly mounted inside the mounting plate 2, an adjustment seat 4 fixedly mounted on the output end of the first electric push rod 3, a first limiting slider 5 slidably connected to the top of the base 1 fixedly mounted on the bottom of the adjustment seat 4, a sliding groove is provided on the top of the base 1, the first limiting slider 5 is slidably connected to the top of the base 1 through the sliding groove, so that when the first electric push rod 3 pushes the adjustment seat 4 to move, the movement of the adjustment seat 4 is limited by the first limiting slider 5 and the sliding groove, so that its moving state remains stable.

[0025] Among them, a driving motor 6 is fixedly installed on the front of the adjusting seat 4, and a screw rod 7 located on the inner wall of the adjusting seat 4 is fixedly installed on the output shaft of the driving motor 6. The outer side of the screw rod 7 is threadedly connected with a movable plate 8 extending to the top of the adjusting seat 4, and a fixed plate 9 is fixedly installed on the top of the movable plate 8. A sliding wheel 10 rollingly connected to the top of the adjusting seat 4 is fixedly installed on the bottom of the fixed plate 9. A second slide groove is opened on the top of the adjusting seat 4, and the sliding wheel 10 is rollingly connected to the top of the adjusting seat 4 through the second slide groove, so that the movement of the fixed plate 9 is smoother through the sliding wheel 10.

[0026] In this embodiment, the adjustment mechanism also includes a fixed seat 11 fixedly installed on the top of the fixed plate 9, a limiting rod 12 is fixedly installed inside the fixed seat 11, a second electric push rod 13 is fixedly installed on the top of the fixed seat 11, and a movable block 14 slidably connected to the limiting rod 12 is fixedly installed on the output end of the second electric push rod 13. A limiting hole is provided inside the movable block 14, and the movable block 14 is slidably connected to the limiting rod 12 through the limiting hole, so that the movable block 14 can be limited by the limiting hole, so that the second electric push rod 13 pushes the movable block 14 to maintain a stable moving state.

[0027] Embodiment 2: The auxiliary component includes a latch seat 15 fixedly installed on the left side of the movable block 14, a latch block 16 fixedly installed inside the latch seat 15, a connecting block 17 is slidably connected to the inner wall of the latch seat 15, a spring 18 is fixedly installed on the right side of the connecting block 17, a limiting groove is provided on the inner wall of the latch seat 15, and the connecting block 17 is slidably connected to the inner wall of the latch seat 15 through the limiting groove, so that the movement of the connecting block 17 can be limited by the limiting groove, so that the connecting block 17 can apply pressure to the spring 18 at a uniform and stable speed.

[0028] Among them, a connecting rod 19 extending to the outside of the latch seat 15 is fixedly installed on the side of the connecting block 17 away from the spring 18, and a contact pad 20 is fixedly installed on the left side of the connecting rod 19. A movable hole is opened on the left side of the latch seat 15. The connecting rod 19 extends to the outside of the latch seat 15 through the movable hole and is fixedly connected to the contact pad 20. When the contact pad 20 contacts the body-in-white, the connecting rod 19 is driven to adjust its position through the movable hole, so that the latch block 16 can achieve soft contact with the body-in-white to avoid damage to the body-in-white.

[0029] It should be noted that the floating locating pin mechanism for the body-in-white adjustment line can install the base 1 in the use position through the adjustment mechanism set up, with the mutual cooperation between the various structures on the base 1. At the same time, when the body-in-white is positioned, it is adjusted according to the position of the locating hole, and the latch block 16 can adapt to body parts of different sizes and shapes, thereby improving the flexibility of positioning. With the cooperation of auxiliary components, elastic elements such as springs 18 are used to enable the latch block 16 to achieve soft contact with the body-in-white when subjected to external forces, thereby avoiding damage to the body-in-white, thereby protecting the body-in-white parts, and the various structures on the base 1 are relatively simple, which is convenient for subsequent maintenance and replacement.

[0030] The working principle of the above embodiment is:

[0031] The floating positioning pin mechanism of the body-in-white adjustment line is used. When the base 1 is installed stably, when the body-in-white needs to be positioned, the driving motor 6 on the adjustment seat 4 is used to rotate to drive the screw 7 to rotate, so that the movable plate 8 drives the fixed plate 9 to adjust its position. While the fixed plate 9 adjusts its position, it drives the fixed seat 11 to move, and the height position of the movable block 14 is adjusted by the second electric push rod 13. When the pin block 16 is aligned with the positioning hole position on the body-in-white, the first electric push rod 3 is used to drive the adjustment seat 4 to approach one side of the body-in-white. During the approach process, the contact pad 20 first contacts the body-in-white, and the spring 18 is compressed by the connecting rod 19 and the connecting block 17, so that the pin block 16 and the body-in-white are slowly plugged in to reduce the damage caused by hard contact.
