Description

Technical Field

[0001] This utility model relates to spin-drying technology, specifically a spin-drying fixture that allows for rapid switching. Background Technology

[0002] Baking paint involves spraying several layers of paint onto a substrate (usually high-density fiberboard) that has been sanded to a certain roughness, drying it, and then baking it at a high temperature to set the shape. This process requires high-quality paint with good color rendering.

[0003] Currently, automotive parts are mainly placed in spin dryers after being painted and then spun dry. However, if painted parts are placed directly in the spin dryer, they will collide with the drum wall, causing dents and scratches to the painted surface. Therefore, a fixing fixture is usually welded inside the spin dryer to fix the painted parts to the bottom of the drum. However, the existing fixtures are directly fixed to the bottom of the spin dryer. Due to the limited space inside the spin dryer, it is extremely difficult to load and unload the workpieces. Moreover, the existing fixtures are all individually designed according to the size of the workpieces and can only be used to fix the same type of workpieces. They cannot be quickly switched and adjusted to adapt to workpieces of different sizes. Utility Model Content

[0004] To address the shortcomings of the prior art, this utility model provides a quick-change spin-drying fixture that can be quickly installed and removed from the bottom of the spin-drying drum. It also allows for adjustment of the positions of the limiting pins, fixing pins, and support pins to accommodate workpieces of different sizes, offering good flexibility.

[0005] To achieve the above technical objectives, this utility model adopts the following technical solution: a quick-switching spin-drying fixture, disposed at the bottom of a spin-drying drum, includes a base plate and at least two fixing units. The base plate has a fixing hole in the middle, and the fixing units are evenly distributed on the base plate. Each fixing unit includes a support column, a fixing pin, and a limiting column. A fixing plate is disposed below the fixing pin, a support plate is disposed below the support column, and a limiting plate is disposed below the limiting column. The fixing plate is disposed on one side of the fixing hole, and the support plate and the limiting plate are respectively disposed at both ends on the other side of the fixing hole. The workpiece is positioned by three points: the support column, the fixing pin, and the limiting column.

[0006] Preferably, a fixing bolt is inserted through the fixing hole, and the fixing bolt is threaded into the bottom wall of the spin dryer.

[0007] Preferably, there are two fixing holes, which are symmetrically arranged at both ends of the middle part of the base plate.

[0008] Preferably, the base plate is provided with a fixing groove, a limiting groove and a supporting groove, the fixing plate is fitted in the fixing groove, the limiting plate is fitted in the limiting groove and the supporting plate is fitted in the supporting groove.

[0009] Preferably, both ends of the fixing groove, the limiting groove and the supporting groove are provided with locking holes, and locking screws are threaded into the locking holes, with the locking screws passing through the fixing plate, the limiting plate or the supporting plate.

[0010] In summary, this utility model achieves the following technical effects:

[0011] This utility model's quick-change spin-drying fixture uses a base plate and fixing bolts for quick assembly and disassembly to the bottom of the spin-drying drum. It also uses locking bolts to secure the limiting posts, fixing pins, and support posts to the base plate. This allows for the selection of different limiting posts, fixing pins, and support posts based on the size and hole positions of the workpiece, thus adapting to different types of workpieces and providing good flexibility.

[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0022] Example 1:

[0023] like Figure 1As shown in Figure 3, a quick-change spin-drying fixture is disposed at the bottom of a spin-drying drum 1, including a base plate 2 and at least two fixing units. The base plate 2 has a fixing hole 3 in the middle, and the fixing units are evenly distributed on the base plate 2. Each fixing unit includes a support column 9, a fixing pin 7, and a limiting column 8. A fixing plate 4 is disposed below the fixing pin 7, a support plate 6 is disposed below the support column 9, and a limiting plate 5 is disposed below the limiting column 8. The fixing plate 4 is disposed on one side of the fixing hole 3, and the support plate 6 and the limiting plate 5 are respectively disposed at both ends on the other side of the fixing hole 3. The workpiece is positioned by three points: the support column 9, the fixing pin 7, and the limiting column 8.

[0024] The quick-change spin-drying fixture of this embodiment uses a base plate 2, which can be quickly installed and removed from the bottom of the spin-drying drum 1 with the help of fixing bolts. Moreover, it uses locking bolts to tighten the limiting post 8, fixing pin 7 and support post 9 to the base plate 2 respectively. Thus, different limiting posts 8, fixing pins 7 and support posts 9 can be selected according to the size and hole position of the workpiece to adapt to different types of workpieces, which is highly flexible.

[0025] The fixing hole 3 is provided with a fixing bolt, which is threaded into the bottom wall of the spin dryer 1; there are two fixing holes 3, which are symmetrically arranged at both ends of the middle part of the base plate 2; the two fixing holes 3 can effectively fasten the base plate 2 to the bottom of the spin dryer 1, avoid the centrifugal force of the spin dryer 1 causing the base plate 2 to swing, and prevent the workpiece from colliding with the wall of the spin dryer 1.

[0026] The base plate 2 is provided with a fixing groove 11, a limiting groove 12 and a supporting groove 13. The fixing plate 4 is fitted into the fixing groove 11, the limiting plate 5 is fitted into the limiting groove 12 and the supporting plate 6 is fitted into the supporting groove 13. The fixing groove 11, the limiting groove 12 and the supporting groove 13 can facilitate workers to quickly position and install the fixing plate 4, the supporting plate 6 and the limiting plate 5.

[0027] Locking holes 14 are provided at both ends of the fixing groove 11, the limiting groove 12, and the supporting groove 13. Locking screws 10 are threaded into the locking holes 14 and pass through the fixing plate 4, the limiting plate 5, or the supporting plate 6. Due to the limitation of the fixing groove 11, the limiting groove 12, and the supporting groove 13, only one of the two locking holes 14 can be used, so that the supporting column 9, the fixing pin 7, and the limiting column 8 can be set at all positions on the top surface of the fixing plate 4, the limiting plate 5, or the supporting plate 6, which increases the adaptability to workpiece size and hole position.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
