[0002] Spray painting fixtures are important equipment used in industrial production to assist in the painting of workpieces. Their main function is to fix and support the workpieces, making the painting process more efficient and uniform, and improving the quality of the paint.

[0003] Currently, most painting fixtures can only paint one side of a workpiece. If the other side needs to be painted, the workpiece must be manually removed, flipped, and re-fixed. This method is not only cumbersome and consumes a lot of manpower and time, but also easily causes scratches or damage to the workpiece surface during manual flipping and re-fixing, affecting the painting quality and the yield of finished products. Alternatively, if the existing painting fixtures have a fixed structure, they cannot be quickly adjusted according to workpieces of different sizes. When it is necessary to paint workpieces of different sizes, it is often necessary to change to different specifications of fixtures, which increases the production cost and equipment management difficulty for enterprises.

[0004] Therefore, a new double-sided painting fixture technology solution is needed that can be quickly adjusted according to the workpiece size. Utility Model Content

[0043] Spray painting fixtures are important equipment used in industrial production to assist in the painting process of workpieces. Their main function is to fix and support the workpiece, making the painting process more efficient and uniform, and improving the painting quality. Traditional spray painting fixtures usually consist of fixed supports and clamps. In use, the workpiece is placed on the support, fixed by the clamps, and then the painting operation is performed. Special spray painting fixtures are needed in the processing of spacecraft components, but such spray painting fixtures have certain shortcomings.

[0044] First, most painting fixtures can only paint one side of a workpiece. If the other side needs to be painted, the workpiece must be manually removed, flipped, and re-fixed. This method is not only cumbersome and time-consuming, but also prone to scratches or damage to the workpiece surface during manual flipping and re-fixing, affecting the painting quality and the yield of finished products. Second, the existing painting fixtures have a fixed structure and cannot be quickly adjusted according to workpieces of different sizes. When it is necessary to paint workpieces of different sizes, it is often necessary to change to different specifications of fixtures, which increases the production cost and equipment management difficulty for enterprises.

[0045] Based on this, the embodiments of this specification propose a double-sided painting fixture that can be quickly adjusted according to the workpiece size. Through the cooperation of the positioning component and the adjustment component, the problem that the existing painting fixture can only paint one side of the workpiece and cannot be quickly adjusted according to workpieces of different sizes is solved.

[0046] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0048] The positioning component 3 is installed on one side opposite to the support plate 2 and includes: a rotating shaft 301 that passes through and connects to the support plate 2; a connecting frame 302 that is fixedly connected to one end of the rotating shaft 301; and a fixing plate 303 that is fixedly connected to one side of the connecting frame 302.

[0049] The positioning electric push rod 304 has its inner cavity fixedly connected to the connecting frame 302, and its telescopic shaft is fixedly connected to the clamping plate 305; the positioning electric push rod 304 is used to drive the clamping plate 305 to move, so as to adapt to workpieces of different sizes and clamp them.

[0050] The clamping plate 305 has grooves 306 on both the top and bottom of one side. A movable plate 307 is movably connected to the inner cavity of the groove 306. A clamping electric push rod 308 is fixedly connected to one side of the movable plate 307, and a bearing plate 309 is fixedly connected to the other side of the clamping electric push rod 308.

[0052] The auxiliary gear 403 is fixedly connected to one end of the rotating shaft 301 and meshes with the main gear 402;

[0053] The motor 401 is used to drive the rotating shaft 301 and the positioning component 3 to rotate through the meshing transmission of the main gear 402 and the auxiliary gear 403, so as to automatically flip the workpiece for double-sided painting.

[0054] The electric clamping push rod 308 is used to drive the movable plate 307 to move, so as to adjust the distance between the clamping plates 305 to accommodate workpieces of different sizes.

[0055] The support plate 309 is used to place the workpiece. Under the action of the clamping electric push rod 308, it can be moved into the inner cavity of the groove 306 to facilitate double-sided painting of the workpiece.

[0056] In some embodiments, limiting sleeves are fixedly connected to both sides of the top of the base 1. The inner cavity of the limiting sleeve is movably connected to the surface of the fixed disk 303. The limiting sleeve is sleeved on the surface of the fixed disk, and the fixed disk has better stability when rotating in the inner cavity of the limiting sleeve, that is, it is used to improve the stability of the fixed disk (303) when rotating.

[0057] In some embodiments, a limiting frame is fixedly connected to the top of one side of the clamping plate 305. The limiting frame is connected through the fixed plate 303. The limiting frame moves in the limiting hole on the surface of the fixed plate as the clamping plate moves. The limiting frame limits the clamping plate to improve the stability of the movement of the clamping plate 305.

[0058] In some embodiments, a limiting ring rail is fixedly connected to one side of the support plate 2, and a limiting cylinder is movably connected to the inner cavity of the limiting ring rail. One side of the limiting cylinder is fixedly connected to the surface of the connecting frame 302. The limiting cylinder rotates in the limiting ring rail with the connecting frame. The limiting structure composed of the limiting ring rail and the limiting cylinder limits the connecting frame, thereby improving the stability of the connecting frame (302) when it rotates.

[0059] In some embodiments, an adjustment seat 5 is fixedly connected to the back of the base 1, and a painting robot arm 6 is provided on the top of the adjustment seat 5. The painting robot arm 6 can move laterally on the top of the adjustment seat 5 and uniformly spray paint on the workpieces between the positioning components through the painting robot arm, so as to achieve uniform painting on the workpieces between the positioning components (3).

[0060] In some embodiments, mounting plates are fixedly connected to both sides of the base 1. The surface of the mounting plates has mounting holes for fixing the painting fixture in a designated position.

[0061] In some embodiments, anti-slip pads are fixedly connected to opposite sides of the clamping plate 305. The surface of the anti-slip pads is provided with anti-slip texture. The anti-slip pads have good anti-slip properties and can improve the clamping effect of the clamping plate 305 by being placed on the surface of the clamping plate.

[0062] Please see Figure 1-7 This utility model is a double-sided spray painting fixture that can be quickly adjusted according to the size of the workpiece. It includes a base 1, and support plates 2 are fixedly connected to both sides of the top of the base 1. A positioning component 3 is provided on one side of the support plate 2, and an adjustment component 4 is provided on the other side of the support plate 2. The positioning component 3 includes a rotating shaft 301, which is connected through the support plate 2. A connecting frame 302 is fixedly connected to one end of the rotating shaft 301. A fixing plate 303 is fixedly connected to one side of the connecting frame 302. A positioning electric push rod 304 is fixedly connected to one side of the inner cavity of the connecting frame 302. A clamping plate 305 is fixedly connected to the telescopic shaft of the positioning electric push rod 304. A groove 306 is provided on the top and bottom of one side of the clamping plate 305. A movable plate 307 is movably connected to the inner cavity of the groove 306. A clamping electric push rod 308 is fixedly connected to one side of the movable plate 307, and a bearing plate 309 is fixedly connected to the other side of the movable plate 307.

[0063] Specifically: The positioning electric push rod 304 is activated. The telescopic shaft of the positioning electric push rod 304 drives the clamping plate 305 to move until the distance between the two clamping plates 305 is suitable for the size of the workpiece to be painted. The workpiece is placed on the support plate 309 between the two clamping plates 305. The positioning electric push rod 304 drives the clamping plate 305 to clamp the workpiece, and painting begins. After one side of the workpiece is painted, the motor 401 is activated. The output shaft of the motor 401 drives the main gear 402 to rotate. The main gear 402 drives the secondary gear 403 to rotate. The secondary gear 403 drives the rotating shaft 301 to rotate. The rotating shaft 301 drives the positioning component 3 to rotate. The positioning component 3 drives the workpiece to rotate until the other side of the workpiece is facing upwards, and the next step of painting continues.

[0064] Please see Figure 1-7 Based on Embodiment 1, the adjustment component 4 includes a motor 401, which is fixedly connected to the support plate 2 via a mounting bracket. The output shaft of the motor 401 is fixedly connected to a main gear 402, and one end of the rotating shaft 301 is fixedly connected to a secondary gear 403. The main gear 402 and the secondary gear 403 mesh. Limit sleeves are fixedly connected to both sides of the top of the base 1. The inner cavity of the limit sleeve is movably connected to the surface of the fixed plate 303. A limit frame is fixedly connected to the top of one side of the clamping plate 305. The limit frame is connected through the fixed plate 303. A limit ring rail is fixedly connected to one side of the support plate 2. A limit cylinder is movably connected to the inner cavity of the limit ring rail. One side of the limit cylinder is fixedly connected to the surface of the connecting frame 302. An adjustment seat 5 is fixedly connected to the back of the base 1. A painting robot arm 6 is provided on the top of the adjustment seat 5. Mounting plates are fixedly connected to both sides of the base 1. Mounting holes are provided on the surface of the mounting plates. Anti-slip pads are fixedly connected to the opposite sides of the clamping plate 305. Anti-slip textures are provided on the surface of the anti-slip pads.

[0065] Specifically: When motor 401 is turned on, its output shaft drives the main gear 402 to rotate. The main gear 402 drives the secondary gear 403 to rotate, which in turn drives the rotating shaft 301 to rotate. The rotating shaft 301 then drives the positioning assembly 3 to rotate. The limiting sleeve is fitted onto the surface of the fixed disk 303. The fixed disk 303 exhibits better stability when rotating within the inner cavity of the limiting sleeve. The limiting frame moves within the limiting hole on the surface of the fixed disk 303 as the clamping plate 305 moves. The limiting frame limits the clamping plate 305, improving its movement stability. The limiting cylinder moves along with the connecting... The frame 302 rotates in the limiting ring rail. The limiting structure composed of the limiting ring rail and the limiting cylinder limits the connecting frame 302, improving the stability of the connecting frame 302 during rotation. The painting robot arm 6 can move laterally on the top of the adjusting seat 5. The painting robot arm 6 sprays paint evenly on the workpieces between the positioning components 3. The mounting bolts are passed through the mounting holes on the surface of the mounting plate and screwed into the ground mounting position, thereby fixing the painting fixture in the designated position. The anti-slip pad has good anti-slip properties and is placed on the surface of the clamping plate 305 to improve the clamping effect of the clamping plate 305.

[0066] The working principle of this utility model is as follows: According to the size of the workpiece to be painted, the positioning electric push rod 304 is activated. The telescopic shaft of the positioning electric push rod 304 drives the clamping plate 305 to move until the distance between the two clamping plates 305 is suitable for the size of the workpiece to be painted. Then, the workpiece is placed on the support plate 309 between the two clamping plates 305. The positioning electric push rod 304 drives the clamping plate 305 to clamp the workpiece, and the painting begins. After one side of the workpiece is painted, the motor 401 is activated. The output shaft of the motor 401 drives the main gear 402 to rotate. The main gear 402 drives the secondary gear 403 to rotate. The secondary gear 403 drives the rotating shaft 301 to rotate. The rotating shaft 301 drives the positioning component 3 to rotate. The positioning component 3 drives the workpiece to rotate until the other side of the workpiece faces upward. At this time, the clamping electric push rod 308 is activated. The telescopic shaft of the clamping electric push rod 308 drives the support plate 309 above the workpiece to move into the inner cavity of the groove 306, and the next painting work can begin.

[0067] This utility model has the following beneficial effects:

[0068] 1. When this utility model is in use, after one side of the workpiece is painted, the motor drives the main gear, the auxiliary gear and the rotating shaft to rotate, so that the positioning component drives the workpiece to automatically flip to the other side facing up, avoiding paint damage or positioning deviation that may be caused by manual flipping. At the same time, opening the clamping electric push rod can drive the support plate above the workpiece to move into the inner cavity of the groove, avoiding the support plate above from affecting the painting of the workpiece. This design not only improves the painting efficiency, but also ensures the uniformity and consistency of double-sided painting through mechanical positioning.

[0069] 2. This utility model uses an electric positioning push rod to move the clamping plate by its telescopic shaft, which precisely adjusts the distance between the two clamping plates until it fits the workpiece size. This design eliminates the need for repeated manual adjustments and can quickly complete the positioning and clamping of the workpiece on the support plate, greatly shortening the clamping time and improving the adaptability of the tooling to workpieces of different sizes.
