Description
Technical Field
[0001] This utility model belongs to the field of automotive trim panel technology, and in particular relates to a fixture for sanding automotive trim panels before spraying. Background Technology
[0002] Automotive trim panels are important decorative parts of automobiles. Before painting, their surfaces need to be sanded to remove burrs, unevenness, or oxide layers, ensuring the adhesion and appearance quality of subsequent painting.
[0003] Currently, existing grinding fixtures typically employ a fixed clamping structure, which is simple and generally only able to clamp and fix decorative panels of a specific size. This makes it difficult to adapt to workpieces of different lengths or to flexibly adjust the required tilt angle of the decorative panel according to the grinding process requirements. Frequent fixture changes are required when processing different models of products, reducing the processing efficiency of the decorative panels. In addition, the fixed clamping method makes it easy to leave grinding dead corners on the surface of the decorative panel during grinding, affecting the grinding quality.
[0004] To address the aforementioned issues, this application proposes a fixture for sanding automotive trim panels before painting. Utility Model Content
[0005] The purpose of this utility model is to provide a fixture for sanding automotive trim panels before painting, which solves the problems mentioned in the background art.

[0032] Please see Figures 1 to 5 As shown, this utility model is a fixture for sanding automotive trim panels before spraying, including a processing table 1 and vertical plates 101 fixed on both sides of its top surface. Its features include: two clamping seats 2, symmetrically arranged above the processing table 1; two translation seats 4, each rotatably mounted with a rotating cylinder 3, the two rotating cylinders 3 being fixedly connected to the two clamping seats 2 respectively, and the two rotating cylinders 3 being connected to the same drive shaft 1601 via a first transmission mechanism; the drive shaft 1001 being connected to two lifting seats 7 via two second transmission mechanisms, the top surface of each lifting seat 7 being fixedly provided with a connecting seat 6, and the two connecting seats 6 being hinged to the two translation seats 4 via connecting rods 5.
[0033] This embodiment provides a fixture for sanding automotive trim panels before painting. Two clamping seats 2 are used to clamp and fix the two ends of the automotive trim panels. When the second drive shaft 1601 rotates, it can drive the two rotating cylinders 3 to rotate through the first transmission mechanism, so as to realize the synchronous rotation of the two clamping seats 2. When the first drive shaft 1001 rotates, it drives the two lifting seats 7 to rise and fall synchronously through the second transmission mechanism. Furthermore, the two lifting seats 7 drive the translation seat 4 to move horizontally through the connecting rod 5, so as to realize the two clamping seats 2 moving closer or further away, and adjusting the distance between the clamping seats 2.
[0034] The first transmission mechanism includes a locking seat 12 fixedly connected to the rotating cylinder 3, and the locking seat 12 is penetrated by the rotating column 13. The locking seat 12 has a groove 1201 that is slidably connected to the locking strip 1301 fixed on the outer wall of the rotating column 13. The locking seat 12 is fixedly connected to the bevel gear 14 via a connecting shaft 1302. The processing table 1 is penetrated by a connecting shaft 1501, and bevel gears 15 are fixed at both ends of the connecting shaft 1501. One bevel gear 15 meshes with the bevel gear 14, and the other bevel gear 15 meshes with the bevel gear 14. Wheel 2 15 meshes with bevel gear 3 16. Bevel gear 3 16 is fixed on the outer wall of drive shaft 2 1601. Drive shaft 2 1601 is fixed to the output end of motor 2 1602. Motor 2 1602 can drive drive shaft 2 1601 to rotate. Furthermore, through bevel gear 3 16, bevel gear 2 15, and bevel gear 1 14, it drives rotating column 13 to rotate. Thus, through snap-fit seat 12, it drives rotating cylinder 3 to rotate synchronously, realizing synchronous rotation of two clamping seats 2 and adjusting the angle of clamping seat 2 and its fixed decorative panel.
[0035] The second transmission mechanism includes a worm gear 10 fixed to the outer wall of the drive shaft 1001, which meshes with a worm wheel 9. The worm wheel 9 is fixed to the lower end of the rotating shaft 8, and the outer wall of the rotating shaft 8 is provided with a threaded section that is threaded to the connecting plate 701. The connecting plate 701 is fixed to the lower end of the lifting seat 7. The drive shaft 1001 is fixed to the output end of the motor 1002. The motor 1002 is used to drive the drive shaft 1001 to rotate, and further drives the worm wheel 9 to rotate through the worm gear 10, thereby driving the rotating shaft 8 to rotate, realizing the vertical movement of the connecting plate 701, and driving the lifting seat 7 to move vertically.
[0036] The bottom surface of the processing table 1 is fixedly provided with a lower protective shell 11. The two ends of the rotating shaft 8 are rotatably connected to the bottom surface of the processing table 1 and the inner bottom surface of the lower protective shell 11, respectively. The motor 1002 is fixedly installed on the outer wall of the lower protective shell 11. The lower protective shell 11 is used to include the rotating shaft 8, the worm gear 9 and the worm 10, and to prevent external impurities from affecting the worm gear and the thread transmission components.
[0037] A guide rod 1101 is fixed between the bottom surface of the processing table 1 and the inner bottom surface of the lower protective shell 11. The guide rod 1101 is slidably connected to the connecting plate 702 fixed at the lower end of the lifting seat 7. The guide rod 1101 and the connecting plate 701 cooperate to restrict the lifting seat 7 to only move vertically, avoid radial displacement during threaded transmission, and improve stability.
[0038] The lifting seat 7 is slidably connected to the slide groove 102 of the processing table 1, and the lifting seat 7 is provided with a clearance groove 703 for avoiding the drive shaft 2 1601. The clearance groove 703 avoids interference between the lifting seat 7 and the drive shaft 2 1601.
[0039] The slide groove 102 is fixedly provided with a smooth block 1021 that is slidably connected to the clearance groove 703. The smooth block 1021 can prevent external impurities from entering the lower protective shell 11 through the slide groove 102.
[0040] Among them, bevel gear 15 and bevel gear 16, which mesh with each other, are set in the protective shell 103 fixed on the bottom surface of the processing table 1. Bevel gear 14 and bevel gear 15, which mesh with each other, are set in the protective shell 104. Motor 1602 is fixed to the outer wall of the protective shell 103. Protective shell 104 is fixed to the vertical plate 101. Protective shell 103 and protective shell 104 are used to protect the gear transmission components, prevent dust pollution and accidental contact, and extend service life.
[0041] It is understood that the two clamping seats 2 of this utility model can rotate synchronously to achieve stepless adjustment of the angle of the clamped decorative panel; at the same time, the clamps of the two clamping seats 2 can be adjusted to adapt to decorative panels of different lengths.
[0042] A specific application of the operation process of this embodiment is as follows: the distance between the two clamping seats 2 is adjusted according to the length of the decorative panel, the motor 1002 is started to drive the drive shaft 1001, the lifting seat 7 is moved vertically through the second transmission structure, and the translation seat 4 is moved horizontally through the connecting rod 5 to adjust the lateral position of the clamping seat 2, and then the two ends of the decorative panel are clamped and fixed through the clamping seat 2.
[0043] When the angle of the trim panel needs to be adjusted, the second motor 1602 is started to drive the second drive shaft 1601 to rotate. The first transmission mechanism causes the rotating cylinder 3 to rotate, which in turn drives the trim panel to rotate through the clamping seat 2, thereby achieving the adjustment of the trim panel angle.
