Technical Field

[0001] This utility model relates to the field of automotive exterior panel assembly technology, specifically to an assembly tooling for automotive pillar exterior panel assemblies. Background Technology

[0002] Automotive pillar trim panels are decorative pieces installed on the door pillars of a car, primarily serving an aesthetic purpose while also protecting the internal metal structure. Pillar trim panels are commonly referred to as pillar panels or pillar decorative panels.

[0003] In the prior art, such as in CN208100199U, a clamping fixture for an automotive brake chamber housing is disclosed. It includes a chamber bottom shell with a through hole and a central hole at the bottom, and a worktable with a fixed platform. The fixed platform is provided with a clamping mechanism that can be raised and lowered and passes through the central hole. The fixed platform is fixed with positioning bolts that match the position of the through hole in its length direction. The worktable has symmetrically fixed support platforms with openings facing the fixed platform and in an arc shape on both sides in the width direction of the fixed platform.

[0004] Although the aforementioned patent secures the outer shell for easier assembly, the various shapes and curved surfaces of the external trim panels during automotive panel assembly make it impossible to adjust and fix the panels in all directions during tooling positioning. Furthermore, the relatively fragile outer shell of the automotive trim panels can cause excessive pressure and deformation during tooling positioning.

[0005] Therefore, this utility model provides an assembly tooling for automotive pillar exterior trim panels. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an assembly fixture for automotive pillar exterior trim panels. This fixture solves the problems of diverse shapes and curved surfaces of trim panels, which make it impossible to adjust and fix the trim panels in all directions during fixture positioning. It also addresses the issue that the relatively fragile exterior trim panel shell can deform under excessive pressure during fixture positioning.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a tooling for assembling an automotive pillar exterior panel assembly, comprising a base plate, wherein the top surface of the base plate is provided with an A-groove and a B-groove in a cross shape, and a support plate is fixedly connected to the side of the base plate at one end of the A-groove and the B-groove, and a cylinder is fixedly connected to the surface of the support plate, wherein sliders are symmetrically connected in pairs inside the A-groove and the B-groove, and a guide post is fixedly connected to the top of the sliders, wherein a groove is provided on one side of the surface of the guide post, and a plurality of directional holes are provided at equal intervals from top to bottom inside the groove, and a spring is provided inside each directional hole, wherein a buffer block is provided at one end of the spring, and a locking mechanism is provided on both sides of the bottom of the guide post in an axially symmetrical manner;

[0008] The locking mechanism includes positioning plates that are fixedly connected to both sides of the bottom of the guide post in an axisymmetric manner. The surface of the positioning plate is provided with a through hole. A damping spring is fixedly connected to the bottom of the positioning plate and below the through hole. A rubber sheet is fixedly connected to the bottom of the damping spring.

[0009] Preferably, the damping spring has a threaded rod inside, and the bottom of the threaded rod is fixedly connected to the top surface of the rubber sheet.

[0010] Preferably, a fixing ring is fixedly connected to the top of the positioning plate and above the through hole, and a locking nut is rotatably connected to the top of the fixing ring, while the top of the threaded rod passes through the interior of the fixing ring and is threadedly connected to the locking nut.

[0011] Preferably, guide holes are provided on the side of the base plate at positions corresponding to the ends of slide A and slide B. One end of the cylinder passes through the interior of the guide hole and is fixedly connected to the surface of the slider. The interiors of slide A and slide B are respectively connected to the guide holes at various positions on the side of the base plate.

[0012] Preferably, the slider has ball bearings on both sides, and the ball bearings are distributed symmetrically on both sides of the slider along a horizontal axis.

[0013] Preferably, the inner sidewalls of both the A and B slides are provided with slide tracks adapted to the ball bearing, and the surface of the ball bearing is slidably connected to the inside of the slide track.

[0014] Beneficial effects

[0015] This utility model provides an assembly fixture for automotive pillar exterior trim panels. Compared with the prior art, it has the following advantages:

[0016] 1. This automotive pillar exterior trim assembly assembly fixture, through the cross-shaped A and B sliding grooves on the base plate, combined with symmetrically sliding sliders and cylinder drive, enables independent adjustment of the trim in four directions: front, back, left, and right. When the curved surface of the trim contacts the guide pillar, the layered springs in the groove push the buffer blocks for graded buffering, ensuring positioning accuracy and avoiding trim indentations caused by rigid contact. This effectively solves the positioning deviation and pressure damage risk in the assembly of curved trim, significantly improving the adaptability to complex curved trim. At the same time, the modular design reduces the cost of replacement and maintenance, meeting the requirements of flexible production of automotive parts.

[0017] 2. The automotive pillar exterior trim assembly assembly fixture uses a locking mechanism at the bottom of the guide pillar. The damping spring and rubber sheet form a two-stage energy absorption structure, absorbing the impact force at the moment of clamping. By rotating the locking nut to adjust the preload of the threaded rod, the dynamic balance of the locking mechanism can adapt to the stable locking requirements of trim panels of different weights and prevent accidental displacement during assembly.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides two technical solutions:

[0025] Figures 1-4 The first embodiment is shown: a tooling for assembling an automotive pillar exterior panel assembly, including a base plate 1. The top surface of the base plate 1 is provided with an A groove 2 and a B groove 3 in a cross shape. Support plates 4 are fixedly connected to the side of the base plate 1 at one end of the A groove 2 and the B groove 3. Cylinders 5 are fixedly connected to the surface of the support plates 4. Slider blocks 6 are symmetrically connected in pairs inside the A groove 2 and the B groove 3. Guide posts 7 are fixedly connected to the top of the sliders 6. A groove 8 is provided on one side of the surface of the guide post 7. A plurality of directional holes are provided at equal intervals from top to bottom inside the groove 8. Springs 9 are provided inside the directional holes. A buffer block 10 is provided at one end of the spring 9. Locking mechanisms 11 are provided on both sides of the bottom of the guide post 7 in an axially symmetrical manner.

[0026] Specifically, the trim panel is gently placed in the center area of ​​the base plate 1, so that its edge contacts the buffer blocks 10 of at least two guide posts 7. The cylinder 5 on the support plate 4 is activated, pushing the symmetrical sliders 6 in the A slide groove 2 and B slide groove 3 to slide towards each other. The sliders 6 move smoothly along the inner slide of the slide groove through the sliding balls 13 on both sides, driving the guide posts 7 to move closer to the trim panel. The cylinders 5 in different directions (up, down, left, right) can be closed according to the curvature of the trim panel to achieve the horizontal sliding adjustment of the four sets of sliders 6. The four sets of guide posts 7 form a surrounding clamping through the buffer blocks 10 in the groove 8. When the curved surface of the trim panel presses against the buffer blocks 10, the springs 9 are compressed in stages. The springs 9 arranged in layers in the groove 8 push the buffer blocks 10 to achieve graded buffering, which ensures positioning accuracy and avoids trim panel indentations caused by rigid contact.

[0027] In this embodiment, the locking mechanism 11 includes a positioning plate 111 fixedly connected to both sides of the bottom of the guide post 7 in an axisymmetric manner. The surface of the positioning plate 111 is provided with a through hole. A damping spring 112 is fixedly connected to the bottom of the positioning plate 111 and below the through hole. A rubber sheet 113 is fixedly connected to the bottom of the damping spring 112. A threaded rod 114 is sleeved inside the damping spring 112. The bottom of the threaded rod 114 is fixedly connected to the top surface of the rubber sheet 113. A fixing ring 115 is fixedly connected to the top of the positioning plate 111 and above the through hole. A locking nut 116 is rotatably connected to the top of the fixing ring 115. The top of the threaded rod 114 passes through the inside of the fixing ring 115 and is threadedly connected to the locking nut 116.

[0028] Specifically, after the cylinder 5 reaches the set position, the locking nut 116 is rotated, causing the threaded rod 114 to move down and the damping spring 112 to be compressed to the preset stroke until the threaded rod 114 contacts the top surface of the base plate 1 through the rubber sheet 113, thereby increasing the friction and achieving locking.

[0029] Figures 1-4The second embodiment is shown. The main difference from the first embodiment is that: guide holes 12 are provided on the side of the base plate 1 at positions corresponding to the ends of slide A 2 and slide B 3. One end of the cylinder 5 passes through the interior of the guide hole 12 and is fixedly connected to the surface of the slider 6. The interiors of slide A 2 and slide B 3 are respectively connected to the guide holes 12 at various positions on the side of the base plate 1. Sliding balls 13 are provided on both sides of the slider 6, and the sliding balls 13 are symmetrically distributed on both sides of the slider 6 along a horizontal axis. The inner sidewalls of slide A 2 and slide B 3 are provided with slide tracks adapted to the sliding balls 13, and the surface of the sliding balls 13 is slidably connected to the interior of the slide tracks.

[0030] Specifically, slide grooves A and B are arranged in a cross shape, and guide holes 12 are respectively opened on the side of the base plate 1, which are on the same horizontal line as slide grooves A and B. This allows the air rod of cylinder 5 to extend through the guide holes 12 and connect with the slider 6. The sliding balls 13 on both sides of the slider 6 roll with the slide rails in the slide grooves, which significantly reduces the sliding resistance, makes the adjustment action driven by cylinder 5 smoother, and improves the tooling response speed and positioning accuracy.

[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0032] Working principle: The outer trim panel of the car pillar is placed in the center area of ​​the base plate 1. The edge of the trim panel naturally contacts the buffer block 10 in the groove 8 of at least two guide pillars 7. The cylinder 5 on the moving support plate 4 pushes the symmetrical slider 6 in the A slide 2 and B slide 3 to slide towards each other. The slider 6 moves smoothly along the inner slide of the slide through the sliding balls 13 on both sides, driving the guide pillar 7 to move closer to the trim panel. When the buffer block 10 of the guide pillar 7 contacts the curved surface of the trim panel, it presses the spring 9 arranged in layers in the groove 8. The spring 9 is compressed step by step, and the buffer block 10 produces a gradual deformation to adapt to the curvature of the curved surface.

[0033] When the guide post 7 reaches the predetermined position, the damping spring 112 of the bottom locking mechanism 11 is compressed and contracts, the rubber sheet 113 generates frictional resistance with the surface of the base plate 1, and at the same time the locking nut 116 is rotated to make the threaded rod 114 descend and press the positioning plate 111.
