Abstract
Description
Technical Field
[0001] This utility model relates to the field of automobile roof manufacturing technology, specifically to a positioning fixture for automobile roof manufacturing. Background Technology
[0002] The base material for car roofs is typically made of materials such as polyurethane foam, fiberglass, and polyester fiber. These materials offer excellent heat and sound insulation, and are also lightweight, reducing the overall weight of the car. After thermoforming, the semi-finished car roof needs to be painted or glued before it can be installed on the vehicle body. However, traditional painting or glue application methods for car roofs have blind spots, such as incomplete painting of the bottom or sides, requiring repeated operations and affecting processing quality and efficiency.
[0003] Existing methods for applying adhesive or paint to car roofs can only operate on one surface or have blind spots, making it difficult to accurately reach the bottom or sides. For example, the car roof adhesive spraying positioning device disclosed in CN220004659U includes a support frame vertically connected to a mounting base, a vertically slidable connecting seat connected to the support frame, and a drive cylinder connected to the mounting base or support frame for driving the connecting seat to slide vertically. The upper end of the connecting seat is connected to a first support component for supporting the upper inner wall of the sunroof opening in the car roof, and the lower end of the connecting seat is connected to a second support component for supporting the lower outer wall of the car roof. The distance between the first and second support components is adjustable. This utility model provides a car roof adhesive spraying positioning device that can better achieve adhesive spraying at the bottom of the car roof and is applicable to positioning various car roofs of different specifications. It has high versatility and reduces the manufacturing cost of car roofs. However, it is not easy to accurately reach the bottom surface of the car roof, affecting the efficiency of adhesive spraying.
[0004] Therefore, it is necessary to invent a positioning fixture for manufacturing automobile roofs to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a positioning fixture for manufacturing car roofs, so as to solve the problem that the bottom and sides of the car roof cannot be uniformly operated during the painting or adhesive spraying operation, resulting in blind spots and low processing efficiency.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A positioning fixture for manufacturing car roofs includes a circular track, a driven gear, a driving gear, and a control motor. The circular track has teeth that mesh with the driven gear and the driving gear. The driving gear is driven by the control motor and is rotatably connected to one side of the positioning fixture base. Each of the four side plates of the positioning fixture base is equipped with an extension baffle. A base plate is fixedly connected to the positioning fixture base, and a cylinder is mounted on the base plate. The cylinder is connected to a clamping body through a lifting rod and a rotating shaft. The clamping body holds the car roof to be painted.
[0008] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0009] 1. This utility model, through the design of a ring track, enables all-round painting or adhesive spraying of the entire base plate and fixture, solving the problem of blind spots in the existing painting operation of car roofs, which leads to the bottom or side surfaces not being operated, thus improving operation efficiency and overall aesthetics.
[0010] 2. This utility model controls the distance between two clamps by installing a cylinder on the base plate, allowing for fine-tuning of the distance between the two clamps. The cylinder can also drive the clamps to rotate, enabling the clamps to better adapt to workpieces with uneven edges, such as car roofs. This results in a wider range of applications for the clamps and greater practicality of the entire tooling. Attached Figure Description

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0020] This utility model provides, for example Figures 1-3 The positioning fixture shown includes a ring track 1, a driven gear 2, a driving gear 3, and a control motor 4. The ring track 1 is provided with teeth that mesh with the driven gear 2 and the driving gear 3. The driving gear 3 is driven by the control motor 4 and is rotatably connected to one side of the positioning fixture base 5. Each of the four side plates of the positioning fixture base 5 is equipped with an extension baffle 6. A base plate 7 is fixedly connected to the positioning fixture base 5. A cylinder 8 is installed on the base plate 7. The cylinder 8 is connected to a clamping body 10 through a lifting rod 801 and a rotating shaft 9. The clamping body 10 holds the car roof to be painted.
[0021] The entire circular track 1 allows the car roof to be clamped between two clamp bodies 10 for 360° all-around painting or adhesive spraying. During the all-around operation, the extension baffle 6 can be used to shield the track, so that the paint or adhesive will not splash onto the circular track 1 during the entire process.
[0022] A servo motor 11 is installed at the bottom of the positioning fixture base 5. The top of the servo motor 11 extends through the positioning fixture base 5 and is connected to a rotating component 1101. A bushing 1102 is connected to the rotating component 1101, and a connecting rod 1103 is connected to the bushing 1102. There are two bushings 1102, and two connecting rods 1103 are connected to the two bushings 1102 respectively. The two connecting rods 1103 are rotatably connected to the bottom of the cylinders 8 on both sides. The bottom of the cylinders 8 on both sides moves along the limiting groove 701, which is opened in the base plate 7.
[0023] The start-up of the servo motor 11 can adjust the relative position of the two cylinders 8, and adjust the distance between the two cylinders 8 to better adapt to the fixed clamping of automotive roof workpieces of different sizes.
[0024] The bottom of the fixture body 10 is provided with a sliding groove 1001, which provides space for the displacement of the lifting rod 801 during the lifting process. The lifting rod 801 can slide and rotate relative to the sliding groove 1001. The top surface of the cylinder 8 is inclined, and the bottom surface of the fixture body 10 can fit with the inclined surface of the cylinder 8. There are also two fixture bodies 10, which are mirror images of each other.
[0025] Slide grooves 1001 are provided at the bottom of both clamp bodies 10 to provide sliding space for the cylinder 8 and the lifting rod 801 to lift. During the lifting process, the lifting rod 801 drives the rotation angle of the clamp body 10.
[0026] The extension baffle 6 is inclined and its bottom surface does not contact the annular track 1. The width of the extension baffle 6 is greater than the width of the annular track 1.
[0027] The function of the extension baffle 6 is to effectively shield the circular track 1 during all-round operation of clamped car roof, keep the circular track 1 clean, and extend the service life of the circular track 1.
[0028] Working principle of this utility model:
[0029] Refer to the instruction manual appendix Figures 1-3 When using this utility model, first clamp and fix the semi-finished car roof to be processed in two clamp bodies 10 (the clamping in the clamp body 10 is also achieved by pneumatically pushing the straight rod above to clamp the semi-finished car roof placed inside), and then you can start to spray paint or apply glue to it.
[0030] Refer to the instruction manual appendix Figures 3-6 When using this utility model, if the edge of the semi-finished car roof is not horizontal, the clamp body 10 can be lifted by the lifting rod 801 in the cylinder 8 to achieve the effect of rotation angle, which is better suited for clamping products with non-horizontal edges.
[0031] When the size of the car roof is small, it is necessary to adjust the distance between the two cylinders 8 (start the servo motor 11 to drive the rotation of the rotating part 1101 and the bushing 1102 to achieve relative proximity or distance between the two cylinders 8).
[0032] The entire painting or adhesive spraying process is from top to bottom (or the nozzle is fixed). Rotating 360° allows for all-around painting or adhesive spraying of the car roof between the two clamp bodies 10, ensuring that the bottom surface of the car roof can also be sprayed. (During the all-around painting or adhesive spraying process, some paint or adhesive may inevitably splash onto the annular track 1, affecting its normal use. The extension baffle 6 acts as a shield during painting or adhesive spraying, ensuring the normal operation of the annular track 1.)
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
