[0003] When spraying paint onto a workpiece, it is necessary to clamp the workpiece and rotate it to ensure that the paint is evenly sprayed onto it. Existing equipment uses magnetic grippers to clamp the workpiece, but this clamping method is not suitable for irregularly shaped workpieces and has the problem of unstable clamping, which affects the workpiece spraying effect. Utility Model Content

[0004] The purpose of this utility model is to propose a spraying rotation mechanism to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A spraying rotation mechanism includes a base plate, on the bottom of which a servo motor and a reducer are mounted and connected. Two pulleys are also mounted on the bottom surface of the base plate. The output shaft of the reducer is fitted with a synchronous belt around the two pulleys. The shaft of the pulleys passes through the top surface of the base plate and is connected to a claw seat. A waterproof cover is provided on the bottom of the claw seat. The claw seat is Y-shaped, and the extended section of the claw seat has a straight groove. Each straight groove of the claw seat is fitted with an adjustable claw, which can be used to clamp workpieces with irregular surfaces.

[0006] As a further description of the above technical solution: The adjustable claw includes a mounting base, a straight rod, a spring, and a sliding groove. The mounting base is connected to the claw seat. There are multiple straight rods, which are slidably connected to the mounting base. Multiple sliding grooves are provided in the mounting base, and the straight rods cooperate with the sliding grooves. A spring is connected between the inner end of the straight rod and the inner wall of the sliding groove.

[0007] As a further description of the above technical solution: The inner end of the straight rod is also provided with a limiting block, and the top surface of the mounting base is provided with a limiting port, which is connected to the sliding groove. The width of the limiting block is greater than the width of the limiting port and less than the width of the sliding groove.

[0008] As a further description of the above technical solution: The top surface of the mounting base is an inclined surface, and the top surfaces of the three mounting bases on the same claw base all face the axis of rotation of the pulley.

[0009] As a further description of the above technical solution: The axis of the straight rod is perpendicular to the top surface of the mounting base.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: In this invention, the adjustable claw, composed of a mounting base, multiple straight rods, and springs, changes the clamping surface from rigid clamping to flexible clamping, resulting in stronger wrapping of irregularly shaped workpiece surfaces and more stable clamping.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Example

[0014] like Figure 1-4As shown, the spraying rotation mechanism includes a base plate 1. A servo motor 2 and a reducer 3 are mounted on the bottom of the base plate 1. The servo motor 2 and the reducer 3 are connected. Two pulleys 4 are also mounted on the bottom surface of the base plate 1. A synchronous belt 5 is fitted around the output shaft of the reducer 3 and the two pulleys 4. The shaft of the pulleys 4 passes through the top surface of the base plate 1 and is connected to a claw seat 7. A waterproof cover 6 is installed on the bottom of the claw seat 7. The claw seat 7 is Y-shaped. A straight groove is opened on the extended section of the claw seat 7. An adjustable claw 8 is installed in each straight groove of the claw seat 7. The adjustable claw 8 can slide and adjust its position inside the straight groove to adjust the size of the workpiece to be clamped. The adjustable claw 8 can be used to clamp workpieces with irregular surfaces. The adjustable claw 8 includes a mounting base 9, a straight rod 10, a spring 11, and a slide 12. The mounting base 9 is connected to the claw seat 7. There are multiple straight rods 10. The 0 is slidably connected to the mounting base 9. The mounting base 9 has multiple sliding grooves 12. The straight rod 10 cooperates with the sliding groove 12. A spring 11 is connected between the inner end of the straight rod 10 and the inner wall of the sliding groove 12. The inner end of the straight rod 10 is also provided with a limiting block 13. A limiting port is opened on the top surface of the mounting base 9. The limiting port is connected to the sliding groove 12. The width of the limiting block 13 is greater than the width of the limiting port and less than the width of the sliding groove 12. The top surface of the mounting base 9 is inclined. The top surfaces of the three mounting bases 9 on the same claw base 7 are all facing the axis of rotation of the pulley 4. The axis of the straight rod 10 is perpendicular to the top surface of the mounting base 9. The adjustable claw 8, composed of the mounting base 9, multiple straight rods 10 and spring 11, changes the clamping surface of the claw from rigid clamping to flexible clamping, which has a stronger wrapping effect on the surface of irregular workpieces and makes the clamping more stable.

[0015] Working principle: When spraying the workpiece, the workpiece is first clamped between the adjustable claws 8. After the straight rods 10 contact the surface of the irregular workpiece, each straight rod 10 automatically extends and retracts, compressing the spring 11 to achieve multi-point wrapping and clamping of the irregular workpiece surface, making the workpiece clamping more stable. After the workpiece clamping is completed, the servo motor 2 and reducer 3 are started. Under the action of the pulley 4 and the synchronous belt 5, the claw seat 7 rotates, taking the workpiece clamped by the adjustable claws 8 with it, so as to cooperate with the external spray head to achieve uniform spraying of the workpiece. There are two claw seats 7, which can clamp two workpieces at the same time for spraying operation.

[0016] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
