Description

Technical Field

[0001] The utility model relates to the technical field of powder coating spraying tooling, in particular to a powder coating spraying fixture device for a plate-shaped structure workpiece. Background Art

[0002] The electrostatic powder spraying process includes surface pretreatment, spraying, baking and curing, etc. The powder coating is sprayed onto the surface of the workpiece with electrostatic powder spraying equipment. Under the action of static electricity, the powder coating will be evenly adsorbed on the surface of the workpiece to form a powdery coating. After high-temperature baking and leveling, it becomes a final coating with different effects. At present, when spraying, the workpiece is basically hung on the chain using a chain overhead guide rail, and then automatically transferred to the powder spraying room for powder spraying, and then baked in a high-temperature furnace. However, for square, rectangular and other plate-shaped workpieces, the hanging process is not easy to achieve, especially for large-mass plates. For small and light-weight plates, they will swing during the spraying process, affecting the spraying effect. Therefore, a fixture suitable for the plate is needed to assist in the spraying process.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0021] See also Figure 1-Figure 4The utility model provides a powder coating spraying fixture device for plate-like structure workpieces, including a rail platform vehicle 1, a positioning base frame 2 is fixedly installed on the top of the rail platform vehicle 1, a top frame 3 is arranged above the positioning base frame 2, and liftable support components are fixedly installed on both sides of the top of the rail platform vehicle 1, the top of the liftable support component is fixedly connected to the bottom of the top frame 3, and a plurality of groups of plate bodies 4 are clamped on the top of the positioning base frame 2. The liftable support component includes a fixed shell 10 fixedly installed on both sides of the top of the rail platform vehicle 1, and the inner cavity of the fixed shell 10 is slidably connected with an adjusting plate 11, and the top of the adjusting plate 11 penetrates the fixed shell 10 and extends to the outside of the fixed shell 10 and is fixedly connected to the bottom of the top frame 3.

[0022] By setting up the liftable support assembly, the distance between the top frame 3 and the positioning base frame 2 can be adjusted to meet the positioning requirements of plates 4 of different sizes. During adjustment, the user can directly move the top frame 3 to adjust the distance between it and the positioning base frame 2. When moving, the top frame 3 will drive the adjustment plate 11 to slide in the inner cavity of the fixed shell 10.

[0023] Preferably, a limiting assembly for limiting the adjusting plate 11 is provided between the surface of the adjusting plate 11 and the inner cavity of the fixed shell 10, and the limiting assembly includes limiting rods 12 fixedly mounted on both sides of the adjusting plate 11, and limiting grooves 13 matching the limiting rods 12 are provided on both sides of the inner cavity of the fixed shell 10, and the surface of the limiting rod 12 is slidably connected to the inner wall of the limiting groove 13.

[0024] By setting the limiting component, the adjusting plate 11 can be limited to prevent the adjusting plate 11 from slipping off the fixed shell 10 and being disconnected therefrom when moving, and by the coordinated use of the limiting rod 12 and the limiting groove 13, the stability of the adjusting plate 11 in the fixed shell 10 can be improved. When the adjusting plate 11 moves, the limiting rod 12 will drive the limiting rod 12 to slide in the inner cavity of the limiting groove 13.

[0025] Among them, a positioning component for locking and fixing the use height of the adjustment plate 11 is also installed on one side of the fixed shell 10. The positioning component includes a positioning tube 14 fixedly installed on one side of the fixed shell 10, and one end of the positioning tube 14 is threadedly connected to a positioning rod 15. One end of the positioning rod 15 passes through the positioning tube 14 and the fixed shell 10 in sequence and extends to the inner cavity of the fixed shell 10 to fit with the surface of the adjustment plate 11.

[0026] By setting the positioning assembly, after adjusting the distance between the top frame 3 and the positioning base frame 2, the user can tighten the positioning rod 15. The rotation of the positioning rod 15 will cause one end of the positioning rod 15 to pass through the positioning tube 14 and the fixed shell 10 in sequence and extend to the inner cavity of the fixed shell 10 to fit with the surface of the adjustment plate 11, thereby locking and fixing the distance between the top frame 3 and the positioning base frame 2.

[0027] It is worth mentioning that a clamping assembly is provided between the top of the plate body 4 and the top frame 3, and the plate body 4 is clamped and fixed to the top of the positioning base frame 2 by the clamping assembly. The clamping assembly includes a clamping frame 5 clamped on the top of the plate body 4, and compression springs 6 are fixedly installed on both sides of the top of the clamping frame 5. The top of the compression spring 6 is fixedly connected to the bottom of the top frame 3. A guide assembly for improving the movement stability of the clamping frame 5 is also provided between the clamping frame 5 and the top frame 3. The guide assembly includes a guide rod 7 fixedly installed on the top of the clamping frame 5, and the compression spring 6 is sleeved on the surface of the guide rod 7. A guide hole 8 compatible with the guide rod 7 is opened on the surface of the top frame 3, and the surface of the guide rod 7 is slidably connected to the inner wall of the guide hole 8. The top of the guide rod 7 passes through the guide hole 8 and extends to the top of the top frame 3. The top of the guide rod 7 is fixedly connected to a pull rod 9.

[0028] Through the setting of the clamping assembly, when fixing the plate body 4, the user can pull the pull rod 9 upwards, and the movement of the pull rod 9 will drive the clamping frame 5 to move through the guide rod 7, and the movement of the clamping frame 5 will squeeze the compression spring 6. At this time, the user can insert the bottom of the plate body 4 into the positioning base frame 2, and then move its position so that the top is directly below the clamping frame 5. At this time, the user can release the pull rod 9, and the reaction force generated by the contraction of the compression spring 6 will push the clamping frame 5 to move downward and be tightly fixed on the top of the plate body 4, thereby positioning the installation position of the plate body 4. After positioning the plate body 4, the user can move the plate body 4 to the powder spraying room for spraying via the rail platform vehicle 1.

[0029] By setting the guide component, the stability of the movement of the clamping frame 5 can be improved. When moving, the clamping frame 5 will drive the guide rod 7 to slide in the inner cavity of the guide hole 8. In addition, in this embodiment, the compression spring 6 is sleeved on the surface of the guide rod 7, which can play an auxiliary supporting role for the compression spring 6 and prevent it from lateral bending during the compression process.
