[0002] Corrosion-resistant functional coatings are coatings that can protect workpieces from corrosion in harsh environments. They form a protective film on the surface of the workpiece, isolating corrosive substances from direct contact with the workpiece, thereby extending the service life of the workpiece. During the coating process, a rotating fixture is required for assistance.

[0003] The existing multi-station rotary fixture for coating includes a mounting cylinder with a clamping mechanism. The clamping mechanism includes a fixed disk with four toothed plates slidably connected inside. The four toothed plates are arranged in a circular array.

A piston block is slidably connected inside the fixed disk, and the lead screw is threaded into the piston block. This fixture can accurately clamp and position cylindrical workpieces using a circular multi-point simultaneous positioning method in actual operation.

[0004] However, in actual use, due to the simple structure of the fixture, it cannot be adapted to workpieces of different shapes, and it is easy to cause misalignment or slippage, resulting in poor clamping stability. Therefore, a workpiece coating rotating fixture is proposed to address the above problems. Utility Model Content

[0005] Technical problem: In view of the problem that the existing fixtures are simple in structure and cannot be adapted to workpieces of different shapes, which easily leads to misalignment or slippage and poor clamping stability, this utility model proposes a workpiece coating rotating fixture.

[0012] Beneficial effects: The significant features of this utility model compared with the prior art are:

[0013] 1. This utility model uses two sets of clamping plates to gradually approach the workpiece.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] like Figure 1-5As shown, a workpiece coating rotating fixture includes a base 1, a support plate 2 mounted on the base 1, a control panel 3 mounted on the side wall of the support plate 2, a guide plate 4 mounted on the support plate 2, two sets of sliding plates 5 slidably connected to the guide plate 4, a clamping plate 6 rotatably mounted on the sliding plate 5, an assembly groove 7 opened inside the clamping plate 6, a push plate 8 slidably mounted in the assembly groove 7, one or more springs 9 installed between the push plate 8 and the inner wall of the assembly groove 7, one or more plate grooves 10 opened on the inner wall of the clamping plate 6, a pressure plate 11 mounted in the plate groove 10, two sets of lifting grooves 12 symmetrically opened on the inner wall of the clamping plate 6, lifting rods 13 slidably mounted in the lifting grooves 12, and the lifting rods 13 are connected to multiple springs 9. The pressure plate 11 is fixedly connected to the side wall. An electric telescopic rod 14 is installed in the lifting groove 12. A push rod 15 is installed on the electric telescopic rod 14. The push rod 15 is fixedly connected to the top side of the lifting rod 13. One or more rod holes 16 are opened on the side wall of the clamping plate 6. A limit rod 17 is installed in the rod hole 16. A first stepper motor 18 is installed on the side wall of one of the sliding plates 5 through a machine base. The output shaft of the first stepper motor 18 is fixedly connected to one of the clamping plates 6. A slide groove 19 is opened in the guide plate 4. Two sets of sliders 20 are symmetrically installed in the slide groove 19. The sliders 20 are fixedly connected to the sliding plate 5. A second stepper motor 21 is installed on the side wall of the guide plate 4 through a machine base. A lead screw 22 is mounted on the output shaft of motor 21. The lead screw 22 is rotatably mounted on the inner wall of slide groove 19, and the thread directions on the lead screw 22 are symmetrical and opposite. During operation, the existing rotating fixture, when used with the coating device to clamp the workpiece, is prone to misalignment or slippage due to its simple structure, which cannot adapt to workpieces of different shapes. This results in poor clamping stability. By placing the workpiece on the rotating plate 27, the second stepper motor 21 is operated to drive the lead screw 22 to rotate. The lead screw 22 drives the two sets of sliders 20 on it to move synchronously relative to each other. The two sets of sliders 20 drive the two sets of sliding plates 5 to move synchronously relative to each other. The two sets of sliding plates 5 drive the two sets of clamping plates 6 to move synchronously relative to each other. As the two sets of clamping plates 6 move relative to each other, they gradually approach the workpiece. During this process, multiple limiting rods 17 on the clamping plates 6 will contact the side wall of the workpiece, and the limiting rods 17 will be pushed into the assembly groove 7. The limiting rods 17 will push the push plate 8 to move backward in the assembly groove 7. Then, the two sets of electric telescopic rods 14 are controlled by the control panel 3. The push rod 15 pushes the lifting rod 13 to move vertically downward. The lifting rod 13 drives multiple sets of pressure plates 11 to move vertically downward. The multiple sets of pressure plates 11 press all the limiting rods 17 together, thus fixing the limiting rods 17. This structure can adapt to workpieces of different shapes, avoid misalignment or slippage, and improve the stability of clamping.

[0024] like Figure 1As shown, two sets of hydraulic cylinders 23 are symmetrically installed on the base 1. Hydraulic rods 24 are mounted on the hydraulic cylinders 23, and a lifting platform 25 is mounted on the hydraulic rods 24. A drive motor 26 is mounted on the bottom side of the lifting platform 25 via a base. A rotating plate 27 is mounted on the output shaft of the drive motor 26, and the rotating plate 27 is rotatably mounted on the lifting platform 25. During operation, existing rotating clamps cannot automatically flip the workpiece during the clamping process with the coating device, resulting in poor flipping convenience. After the workpiece is clamped and fixed by two sets of clamping plates 6, the first stepper motor 18 operates, driving the clamping plates 6 to rotate 360°. The clamping plates 6 then drive the workpiece clamped on them to rotate 360°, achieving coating on all four sides of the workpiece. After coating, hydraulic cylinder 23 operates, and hydraulic rod 24 pushes lifting platform 25 to move vertically upward. Lifting platform 25 drives rotating plate 27 to move vertically upward. Then, two sets of clamping plates 6 release the workpiece, which is placed on rotating plate 27. Drive motor 26 operates, driving rotating plate 27 to rotate 90°. Rotating plate 27 drives the workpiece on it to rotate 90°, realizing rapid flipping of the workpiece. Then, two sets of clamping plates 6 clamp and fix the workpiece again. Hydraulic rod 24 drives lifting platform 25 to move vertically downward. Clamping plates 6 drive the workpiece on them to rotate 360°, realizing full coating of the workpiece. This structure can automatically flip the workpiece, which is beneficial to improving the convenience of workpiece flipping.

[0025] Working principle: Existing rotating fixtures, when used with a coating device to hold workpieces, suffer from poor stability due to their simple structure, inability to adapt to workpieces of different shapes, and susceptibility to misalignment or slippage. By placing the workpiece on the rotating plate 27, the second stepper motor 21 rotates the lead screw 22, which in turn moves two sets of sliders 20 synchronously relative to each other. These sliders 20, in turn, move two sets of sliding plates 5 synchronously relative to each other, which in turn move two sets of clamping plates 6 synchronously relative to each other. The two sets of clamping plates 6 gradually move towards... As the workpiece approaches, multiple limiting rods 17 on the clamping plate 6 contact the side wall of the workpiece. Simultaneously, the limiting rods 17 are pushed into the assembly groove 7, pushing the push plate 8 backward within the assembly groove 7. Then, the control panel 3 controls the operation of two sets of electric telescopic rods 14. The push rod 15 pushes the lifting rod 13 vertically downward, which in turn moves multiple sets of pressure plates 11 vertically downward. Together, the pressure plates 11 press down on all the limiting rods 17, thus fixing them in place. This structure can adapt to workpieces of different shapes, preventing misalignment. In cases of slippage or misalignment, this improves clamping stability. Existing rotating clamps, when used with a coating device to hold workpieces, cannot automatically flip over, resulting in poor flipping convenience. After the workpiece is clamped and fixed by two sets of clamping plates 6, the first stepper motor 18 operates, driving the clamping plates 6 to rotate 360°. The clamping plates 6 then rotate the workpiece they hold 360°, enabling coating processing on all four sides of the workpiece. Afterwards, the hydraulic cylinder 23 operates, and the hydraulic rod 24 pushes the lifting platform 25 vertically upward. The lifting platform 25 then drives the rotating plate 27 vertically upward. The workpiece moves straight upwards, and then the two sets of clamping plates 6 release the workpiece, which is then placed on the rotating plate 27. The drive motor 26 operates, causing the rotating plate 27 to rotate 90°, which in turn causes the workpiece on it to rotate 90°, thus achieving rapid flipping of the workpiece. Afterwards, the two sets of clamping plates 6 clamp and fix the workpiece again, and the hydraulic rod 24 drives the lifting platform 25 to move vertically downwards. The clamping plates 6 cause the workpiece on them to rotate 360°, thus achieving full coating processing of the workpiece. This structure can automatically flip the workpiece, which helps to improve the convenience of workpiece flipping.
