Description

Technical Field

[0001] This utility model relates to the field of powder coating fixtures, specifically a powder coating fixture for small workpieces. Background Technology

[0002] Powder coating is a coating process that uses corona discharge to make powder coatings adhere to the workpiece. It can improve the workpiece's corrosion resistance, wear resistance and aesthetics. It usually consists of several steps, such as degreasing, sandblasting, grinding, powder coating and baking. In actual operation, small workpieces are usually suspended, and then powder coating machines are used to spray the workpieces to be treated. Then the workpieces are sent into the baking room for baking to complete the powder coating process.

[0003] Chinese utility model patent CN222112238U discloses a powder coating hanger for automotive parts. By incorporating a portable device, the hanger can better suspend and powder coat multiple automotive parts during use, preventing contact between parts and thus avoiding powder coating dead zones, thereby improving the hanger's effectiveness and increasing the efficiency of parts powder coating. However, during powder coating, the air pressure from the powder coating machine creates significant pressure on the workpiece, causing it to shift on the hanger and come into contact with the hanger's rod, resulting in powder coating dead zones. This necessitates manual adjustment for powder coating, affecting both powder coating quality and efficiency. Utility Model Content

[0004] In view of the problem that workpieces are prone to displacement in the existing technology, resulting in contact with the hanger rod, creating dead angles for powder spraying, and affecting the powder spraying quality and efficiency, this utility model provides a powder spraying hanger for small workpieces.

[0005] The present invention discloses a powder coating fixture for small workpieces, comprising: a fixture assembly, which includes a lifting rod and a fixture component. One end of the lifting rod is provided with an adjustment hole, and one end of the fixture component is connected to the lifting rod and extends to the outside through the adjustment hole. There are two adjustment holes and two fixture components, which are arranged opposite to each other, and the two adjustment holes form an "eight" shape.

[0006] Preferably, the inner cavity of the hanging rod is provided with a movable cavity located on one side of the adjustment hole, and the movable cavity allows the hanging device to move up and down.

[0007] Preferably, a powder spraying fixture for small workpieces further includes a movable component, which includes a movable block and an elastic element. The movable block is fitted into the adjustment hole, and one end of each of the two fixture parts is connected to the movable block. The elastic element is connected to one end of the movable block, and the other end of the elastic element is connected to one end of the adjustment hole.

[0008] Preferably, the movable block has a limiting cavity.

[0009] Preferably, the cross-section of the limiting cavity is an isosceles trapezoid.

[0010] Preferably, the movable block has a limiting part in the middle.

[0011] Preferably, the hanging component is L-shaped, and one end is connected to the movable block.

[0012] Preferably, the two hanging parts are hinged at one end to the movable block.

[0013] Preferably, a powder spraying fixture for small workpieces further includes a limiting component. The end of the fixture away from the movable block is provided with a plurality of limiting holes. The limiting component includes a limiting block, and the plurality of limiting blocks are sleeved in the plurality of limiting holes.

[0014] Preferably, the limiting component further includes a reset plate, with two reset plates respectively disposed on opposite sides of the two hanging parts, and the two ends of the reset plate respectively connected to the limiting block closest to the movable block and the limiting block furthest from the movable block.

[0015] Compared with the prior art, this utility model provides a powder spraying fixture for small workpieces, which has the following beneficial effects:

[0016] 1. This small workpiece uses a powder spraying fixture. Two figure-eight shaped adjustment holes are opened at one end of the hanging rod. These holes guide the two fixture components, allowing the angle between them to increase with the weight of the suspended workpiece. When the workpiece is placed on the fixture, its weight causes the fixture to open to the same size as the suspension hole on the workpiece. The weight of the workpiece applies pressure to the suspension hole, thus fixing the workpiece in place. This prevents the workpiece from being impacted during powder spraying, which could cause displacement, obstruct the powder spraying, create dead zones, and affect the quality and efficiency of the powder spraying.

[0017] 2. The powder spraying fixture for small workpieces, by setting up movable components, allows the fixture to automatically reset under the action of the elastic element after the workpiece is removed from the powder spraying process. The fixture returns to its closed state along the adjustment hole, which facilitates the hanging of subsequent workpieces on the fixture and improves the powder spraying efficiency.

[0018] 3. The powder spraying fixture for this small workpiece, by setting a limiting component, allows the limiting block to be gradually pushed to the middle of the two fixtures under pressure when the fixture gradually opens along the adjustment hole after the workpiece to be reinforced is suspended on the fixture. The protruding part can be locked in the threaded groove of the workpiece suspension hole, thereby further restricting the movement of the workpiece to be processed and improving the powder spraying quality and efficiency.

[0029] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0030] The following specific examples illustrate the implementation of this disclosure. Those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. This disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0031] Reference Figures 1-2 , Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a schematic diagram of the structure of the hanging fixture assembly of this utility model. A powder spraying fixture for small workpieces includes: a hanging fixture assembly 1 including a hanging rod 11 and a hanging fixture 12. One end of the hanging rod 11 has an adjustment hole 111. One end of the hanging fixture 12 is connected to the hanging rod 11 and extends to the outside through the adjustment hole 111. There are two adjustment holes 111 and two hanging fixtures 12, which are arranged opposite to each other. The two adjustment holes 111 form an "eight" shape. Under normal conditions, the hanging fixture 12 is located at the uppermost part of the adjustment hole 111. After the workpiece to be processed is suspended on the hanging fixture 12, under the action of gravity, the workpiece to be processed drives the hanging fixture 12 to move downward, so that the two hanging fixtures 12 are guided by the two adjustment holes 111 to gradually open.

[0032] The workpiece that needs to be powder coated is called the workpiece to be processed. When suspending, the hanger 12 is usually passed through the suspension hole opened on the workpiece to be processed, so that the workpiece to be processed is suspended on the hanger 12.

[0033] The suspension holes on the workpiece to be processed are usually threaded holes or splicing holes for assembling the workpiece.

[0034] This small workpiece powder spraying fixture has two figure-eight shaped adjustment holes 111 at one end of the hanging rod 11. The two adjustment holes 111 guide the two hanging fixtures 12 respectively, so that the angle between the hanging fixtures 12 can increase with the weight of the suspended workpiece. After the workpiece to be processed is placed on the hanging fixture 12, under the action of the workpiece's gravity, the hanging fixture 12 opens to the same size as the suspension hole on the workpiece. Under the action of gravity, pressure is applied to the suspension hole, thereby limiting the position of the workpiece to be processed. This avoids the workpiece being impacted during powder spraying, causing displacement of the workpiece, which would result in the hanging rod 11 blocking the powder spraying of the workpiece, creating dead angles, and affecting the powder spraying quality and efficiency.

[0035] Reference Figure 3 , Figure 3 This is a schematic diagram of the movable component structure of this utility model. The inner cavity of the hanging rod 11 has a movable cavity 112 located on one side of the adjustment hole 111, and the movable cavity 112 allows the hanging fixture 12 to move up and down, ensuring that when the workpiece to be processed is suspended on the hanging fixture 12, the hanging fixture 12 moves downward as a whole, so that the two hanging fixtures 12 can be opened in a horizontal state to limit the workpiece to be processed, avoiding the hanging fixture 12 from tilting as a whole, which would cause the workpiece to tilt and easily slip off, and further ensuring the suspension quality.

[0036] Rereference Figure 3 A powder spraying fixture for small workpieces also includes a movable component 2. The movable component 2 includes a movable block 21 and an elastic element 22. The movable block 21 is fitted into the adjustment hole 111, and one end of the two fixture parts 12 is connected to the movable block 21. The elastic element 22 is connected to one end of the movable block 21, and the other end of the elastic element 22 is connected to one end of the adjustment hole 111. Under normal conditions, the elastic element 22 applies a spring force to the movable block 21, causing the movable block 21 to move one end of the fixture part 12 to the position at the uppermost end of the adjustment hole 111. When subjected to the gravity of the workpiece to be processed, it overcomes the spring force of the elastic element 22, causing the movable block 21 to move the fixture part 12 downward.

[0037] Specifically, the elastic element 22 is a spring, and during installation, the elastic element 22 can be placed above or below the movable block 21, so that the movable block 21 can be automatically reset by elastic force or tension.

[0038] The small workpiece powder spraying fixture, by setting the movable component 2, allows the movable block 21 to automatically reset the fixture after the workpiece is removed, under the action of the elastic component 22, and the fixture 12 to return to the closed state along the adjustment hole 111. This makes it easier for subsequent workpieces to be processed to be suspended on the fixture 12, thus improving the powder spraying efficiency.

[0039] Reference Figures 3-4 , Figure 4 This is a schematic diagram of the movable block structure of this utility model. The movable block 21 has a limiting cavity 211, which restricts the hanging part 12 from moving up and down relative to the movable block 21. This ensures that the hanging part 12 can only open or close relative to the movable block 21, further ensuring that the workpiece to be processed will not tilt when suspended.

[0040] Specifically, the cross-section of the limiting cavity 211 is an isosceles trapezoid.

[0041] The movable block 21 has a limiting part 212 in the middle, and the limiting part 212 is located in the middle of the two hanging parts 12, and limits the two hanging parts 12 to ensure that one end of the two hanging parts 12 can always be located in the limiting cavity 211, so that the hanging parts 12 will not separate from the movable block 21 due to vibration or powder impact, thus affecting the suspension effect.

[0042] The hanger 12 is L-shaped and one end is connected to the movable block 21, so that the shape of the hanger 12 itself can limit the slippage of the workpiece to be processed.

[0043] The two hanging parts 12 are hinged at one end to the movable block 21, which ensures that the two hanging parts 12 can open and close more flexibly and ensures the stability of the connection between the two hanging parts 12.

[0044] Reference Figures 5-6 , Figure 5 This is a schematic diagram of the structure of the hanging component of this utility model; Figure 6 This utility model Figure 5 Enlarged schematic diagram of the structure at point A. A powder spraying fixture for small workpieces also includes a limiting component 3. The end of the fixture 12 away from the movable block 21 is provided with multiple limiting holes 121. The limiting component 3 includes a limiting block 31, and the multiple limiting blocks 31 are sleeved in the multiple limiting holes 121.

[0045] The small workpiece powder spraying fixture, by setting a limiting component 3, allows the limiting block 31 to be gradually pushed to the middle of the two fixture components 12 under pressure when the workpiece to be reinforced is suspended on the fixture component 12 and the fixture component 12 gradually opens along the adjusting hole 111 under the action of gravity. The protruding part can be just locked in the threaded groove of the workpiece suspension hole, thereby further restricting the movement of the workpiece to be processed and improving the powder spraying quality and efficiency.

[0046] The limiting component 3 also includes a reset plate 32. The two reset plates 32 are respectively disposed on opposite sides of the two hangers 12, and the two ends of the reset plate 32 are respectively connected to the limiting block 31 closest to the movable block 21 and the limiting block 31 furthest from the movable block 21. This allows the hangers 12 to automatically reset under the action of the elastic member 22 after the workpiece suspended on the hanger 12 is removed, so that the two hangers 12 move closer to each other. Under the action of the two reset plates 32 contacting each other, the reset plates 32 push all the limiting blocks 31 from the side of the hanger 12 furthest from the reset plate 32, and automatically reset. This ensures that when the workpiece to be processed is suspended again, the limiting blocks 31 can restrict the workpiece to be processed again, and ensures the stability of the reset.
