Abstract
Description
Technical Field
[0001] This utility model relates to the field of shot blasting equipment technology, specifically a shot blasting equipment manufactured by an industrial robot. Background Technology
[0002] Shot blasting equipment manufactured using industrial robots is a device used for cleaning and treating the surface of workpieces. This equipment utilizes a high-speed rotating shot blaster to propel abrasive particles at high speed onto the workpiece surface, thereby removing scale, rust, or surface contaminants, while simultaneously increasing surface roughness to enhance the adhesion of coatings or other subsequent processes. Its features include working in conjunction with industrial robots to achieve multi-angle, precise surface treatment, and providing efficient and uniform processing results for workpieces with complex shapes.
[0003] In existing shot blasting equipment, when the nozzle angle is fixed, the coverage area of the blasting zone is preset. If the workpiece surface has a complex shape or unevenness, some areas may exceed the blasting range, resulting in particles not uniformly covering the entire surface. According to the principles of geometric optics, the blasting range at a fixed angle is conical, effective only for the surface within the conical region. Some parts of complex workpieces may not be covered, causing uneven coating. Furthermore, the kinetic energy of the blasted particles gradually decreases after leaving the nozzle. According to the principles of momentum conservation and air resistance, the further the particles travel along the blasting path, the more significant the velocity reduction, and the weaker the impact force on the workpiece surface. This phenomenon is particularly pronounced at the edges of the conical distribution, making the coating effect at the edges far less effective than in the center. The fixed nozzle angle design also leads to uneven particle distribution within the conical range. According to fluid dynamics principles, the particle density is highest and the impact force is strongest in the central region of the jet stream, while the particle density gradually decreases near the edges. This characteristic of particle density distribution results in a denser coating at the center and a sparser coating at the edges, further exacerbating the problem of uneven coating.
[0004] In view of this, we propose a shot blasting device for industrial robot manufacturing. Utility Model Content
[0005] The purpose of this utility model is to provide a shot blasting device for industrial robot manufacturing. This shot blasting device for industrial robot manufacturing solves the problems of limited spraying range, particle kinetic energy attenuation and uneven distribution caused by fixed nozzle angle, making it difficult to achieve uniform spraying on complex workpiece surfaces.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a shot blasting device for manufacturing industrial robots, comprising a body, the body including a spraying mechanism, the spraying mechanism including: an inlet pipe, a fixing block fixedly connected to the inner wall of the inlet pipe, one end of a spring fixedly connected to the outer wall of the fixing block, a positioning plate fixedly connected to the other end of the spring, a through ring fixedly connected to the inner wall of the inlet pipe, a guide rod fixedly connected to the outer wall of the positioning plate, a hollow rotating disk rotatably connected to the inner wall of the inlet pipe, an oblique spraying pipe fixedly connected to the inner wall of the hollow rotating disk, an annular connector fixedly connected to the outer wall of the positioning plate, and a trigger rod fixedly connected to the outer wall of the annular connector; a suspension mechanism is provided at the top of the body.
[0007] Preferably, the outer wall of the guide rod is slidably connected to the inner wall of the fixing block, and the inner wall of the annular connector is connected to the outer piston of the inlet pipe.
[0008] Preferably, there are two oblique injection pipes, which are arranged in a circumferential array.
[0009] Preferably, the annular connector is L-shaped, and the inner wall of the inlet pipe is connected to the inner wall of the hollow rotating disk.
[0010] Preferably, the suspension mechanism includes a slide rail, which is fixedly connected to the top of the machine body. A power component is provided at the bottom of the slide rail, and a suspension rod is fixedly connected to the bottom of the power component. A ratchet is rotatably connected to the bottom of the suspension rod, and a hook is fixedly connected to the bottom of the ratchet.
[0011] Preferably, one end of a spiral spring is fixedly connected to the outer wall of the suspension rod, and the other end of the spiral spring is fixedly connected to a connecting ring. The bottom of the connecting ring is fixedly connected to a ratchet. A fixing plate is fixedly connected to the outer wall of the machine body. One end of a second spring is fixedly connected to the outer wall of the fixing plate. The other end of the second spring is fixedly connected to a ratchet.

[0012] Preferably, the outer wall of the lightweight rod is slidably connected to the inner wall of the fixed plate, and the outer wall of the ratchet is fixedly connected to an L-shaped connector.
[0013] By employing the above technical solution, this utility model provides a shot blasting device for manufacturing industrial robots. It possesses at least the following beneficial effects:
[0014] (1) This utility model incorporates a spraying mechanism. The material to be sprayed is injected into the inlet pipe, then enters the hollow rotating disk and is sprayed out through the angled spray pipe. The reaction force of the angled spray pipe during spraying drives the hollow rotating disk to rotate, which in turn drives the angled spray pipe to rotate and spray. The rotation of the hollow rotating disk causes the spraying direction of the angled spray pipe to continuously change, expanding from a fixed spray point to a dynamically covered circumferential area, effectively improving the spraying coverage, and is especially suitable for large or complex-shaped workpieces. Rotary spraying ensures that the particles are evenly distributed on the workpiece surface, avoiding the problem of excessive or insufficient local spraying caused by static spraying, and improving the consistency of spraying or cleaning effects.
[0015] (2) This utility model incorporates a suspension mechanism. As the material injected through the inlet pipe enters the hollow rotating disc, it pushes the positioning disc. The positioning disc drives the annular connector and the trigger rod. The trigger rod abuts against the L-shaped connector, causing the L-shaped connector to move the ratchet towards the fixed plate. This disengages the ratchet from the ratchet, and the ratchet and connecting ring are then driven by the force released by the spiral spring. The ratchet drives the hook and workpiece to rotate. This process allows the workpiece to rotate automatically according to the spraying requirements, ensuring uniform spraying or processing of the material. It avoids the tedious manual adjustment of the workpiece position and improves the automation level of the operation. Attached Figure Description

[0025] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1-7 As shown, this utility model provides a technical solution: a shot blasting device for manufacturing industrial robots, including a body 1, the body 1 including a spraying mechanism 2, the spraying mechanism 2 including: an inlet pipe 21, a fixing block 22 fixedly connected to the inner wall of the inlet pipe 21, a spring-23 fixedly connected to one end of the outer wall of the fixing block 22, a positioning plate 24 fixedly connected to the other end of the spring-23, a through ring 25 fixedly connected to the inner wall of the inlet pipe 21, a guide rod 26 fixedly connected to the outer wall of the positioning plate 24, a hollow rotating plate 27 rotatably connected to the inner wall of the inlet pipe 21, an oblique spraying pipe 28 fixedly connected to the inner wall of the hollow rotating plate 27, an annular connector 29 fixedly connected to the outer wall of the positioning plate 24, and a trigger rod 210 fixedly connected to the outer wall of the annular connector 29; a suspension mechanism 3 is provided at the top of the body 1, the outer wall of the guide rod 26 is connected to the fixed ring 25, and the guide rod 26 is fixedly connected to the outer wall of the positioning plate 24. The inner wall of the fixed block 22 is slidably connected, and the inner wall of the annular connector 29 is connected to the outer piston of the inlet pipe 21. There are two oblique spray pipes 28, which are arranged in a circumferential array. When the oblique spray pipes 28 spray, they will be driven by the reaction force to rotate the hollow rotating disk 27. The hollow rotating disk 27 rotates under the drive of the reaction force, so that the spray direction of the oblique spray pipes 28 changes continuously, thereby achieving a dynamic 360° coverage range, improving the uniformity of the workpiece surface treatment, and is especially suitable for workpieces with complex shapes or large surfaces. Through the rotational movement, the sprayed particles cover the workpiece surface at multiple angles and directions without the need to increase the number of nozzles, thereby completing a wider range of spraying or cleaning in a certain period of time and improving work efficiency. The annular connector 29 is L-shaped, and the inner wall of the inlet pipe 21 is connected to the inner wall of the hollow rotating disk 27.
[0027] The suspension mechanism 3 includes a slide rail 31, which is fixedly connected to the top of the machine body 1. A power component 32 is provided at the bottom of the slide rail 31, and a suspension rod 33 is fixedly connected to the bottom of the power component 32. A ratchet 34 is rotatably connected to the bottom of the suspension rod 33, and a hook 35 is fixedly connected to the bottom of the ratchet 34. The power component 32 drives the suspension rod 33, ratchet 34, and hook 35 to move, so that the industrial robot on the hook 35 is moved into the machine body 1 to prepare for shot blasting. A spiral spring 3 is fixedly connected to the outer wall of the suspension rod 33. One end of the spiral spring 36 is fixedly connected to a connecting ring 37. The bottom of the connecting ring 37 is fixedly connected to a ratchet 34. A fixing plate 38 is fixedly connected to the outer wall of the body 1. One end of a second spring 39 is fixedly connected to the outer wall of the fixing plate 38. A ratchet 310 is fixedly connected to the other end of the second spring 39. A lightweight rod 311 is fixedly connected to the outer wall of the ratchet 310. The outer wall of the lightweight rod 311 is slidably connected to the inner wall of the fixing plate 38. An L-shaped connector 312 is fixedly connected to the outer wall of the ratchet 310.
[0028] When using the shot blasting device for manufacturing industrial robots according to this utility model, the industrial robot to be shot blasted is hung on the hook 35, and then the power component 32 is activated to drive the suspension rod 33 to move towards the L-shaped connector 312. The suspension rod 33 drives the ratchet 34 to move towards the L-shaped connector 312. While the ratchet 34 is moving, it meshes with the ratchet 310 and rotates. The rotation of the ratchet 34 drives the connecting ring 37 to rotate, and the connecting ring 37 drives the spiral spring 36 to store force.
[0029] The material to be sprayed is injected into the inlet pipe 21, then enters the hollow rotating disk 27 and is sprayed out through the angled spray pipe 28. The reaction force of the angled spray pipe 28 when it is sprayed out drives the hollow rotating disk 27 to rotate, which in turn drives the angled spray pipe 28 to rotate and spray. The rotation of the hollow rotating disk 27 causes the spray direction of the angled spray pipe 28 to continuously change, expanding from a fixed spray point to a dynamically covered circumferential area, effectively improving the spray coverage, especially suitable for large or complex-shaped workpieces. Rotary spraying ensures that the particles are evenly distributed on the workpiece surface, avoiding the problem of excessive or insufficient local spraying caused by static spraying, and improving the consistency of spraying or cleaning effect.
[0030] As the material injected into the inlet pipe 21 enters the hollow rotating disk 27, it pushes the positioning disk 24. The positioning disk 24 drives the annular connector 29 and the trigger rod 210. The trigger rod 210 abuts against the L-shaped connector 312, causing the L-shaped connector 312 to move the ratchet 310 towards the fixed plate 38. This causes the ratchet 310 to disengage from the ratchet 34. At this time, the ratchet 34 and the connecting ring 37 are driven by the force released by the spiral spring 36. The ratchet 34 drives the hook 35 and the workpiece to rotate. This process allows the workpiece to rotate automatically according to the spraying requirements, ensuring uniform spraying or processing of the material, avoiding the tedious manual adjustment of the workpiece position, and improving the automation level of the operation.
