Description

Technical Field

[0001] The present application relates to the technical field of sandblasting equipment, and in particular to a sandblasting robot for offshore engineering machinery processing. Background Art

[0002] Sandblasting uses compressed air as a power source to form a high-speed jet beam to spray the material (copper ore sand, quartz sand, corundum, iron sand, etc.) at high speed onto the surface of the workpiece to be processed, so that the outer surface or shape of the workpiece surface changes. Due to the impact and cutting action of the abrasive on the workpiece surface, the surface of the workpiece obtains a certain degree of cleanliness and different degrees of roughness, and the mechanical properties of the workpiece surface are improved, thereby improving the fatigue resistance of the workpiece, increasing the adhesion between it and the coating, extending the durability of the coating, and also facilitating the leveling and decoration of the coating. For example, when processing ship workpieces, pomegranate sand is often used for sandblasting. The amount of pomegranate sand used for the same sandblasting area can be saved by one-third, that is, the use of pomegranate sand has a large sandblasting area per unit time, less sand consumption per unit area, and low sandblasting cost.

[0003] Under the existing technology, when performing sandblasting, sandblasting workers generally hold a spray gun to manually blast the outer wall of the workpiece to be processed. Due to the limited strength of the sandblasting workers, they cannot use a nozzle with a larger diameter, resulting in low shot blasting efficiency. In addition, since the spray gun covers a small area, the worker needs to adjust the position more frequently, which affects the processing efficiency. Utility Model Content

DETAILED DESCRIPTION

[0018] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0019] The present application embodiment discloses a sandblasting robot for marine engineering machinery processing. Figure 1 and Figure 4 The sandblasting robot for marine engineering machinery processing may include a ball screw structure, a travel assembly 20 and one or two groups of sandblasting assemblies 30. The ball screw structure is fixed on the top of the sandblasting room 10 and driven by a motor. The travel assembly 20 is connected to the ball screw structure so that it can be driven by the screw seat to move along the axial direction of the ball screw structure. The travel assembly 20 has at least one group of movable parts that move laterally. The movable part of the travel assembly 20 drives the connection of the sandblasting assembly 30 to adjust the position of the sandblasting assembly 30 so that there is a suitable distance between the sandblasting assembly 30 and the workpiece to be processed. During sandblasting, the spray gun 39 in the sandblasting assembly 30 can be driven to adjust the direction and position of the workpiece for sandblasting.

[0020] See also Figure 2The traveling assembly 20 includes a crossbeam 21, and at least one set of sliding brackets 24 and traveling brackets 25 are fixedly installed on the top of the crossbeam 21. The sliding bracket 24 passes through the steel beam and supports the traveling assembly 20 and the sandblasting assembly 30 below the steel beam. The traveling bracket 25 is fixed to the wire seat and passed through by the ball screw, so that the crossbeam 21 moves along the axial movement of the ball screw by the traveling bracket 25 and the wire seat. The inner top of the crossbeam 21 is fixedly connected to a guide rod whose length matches the length of the crossbeam 21. The top hanging ear of the hanger 31 in the sandblasting assembly 30 is slidably sleeved on the guide rod to guide the movement of the sandblasting assembly 30 toward or away from the workpiece. At least one set of mounting brackets 22 is fixedly connected to the bottom of the crossbeam 21, and a transverse pneumatic cylinder 23 is fixedly installed on the mounting bracket 22. The output end of the transverse pneumatic cylinder 23 is connected to the hanging ear on the outer wall of the hanger 31 in the sandblasting assembly 30. The output end of the transverse air cylinder 23 constitutes the movable part of the traveling assembly 20, and its output end can drive the sandblasting assembly 30 to move axially along the guide rod.

[0021] See also Figure 3The sandblasting assembly 30 includes a hanger 31, a first angle adjustment frame 32, a first motor 33, a second motor 34, a worm 35, a worm wheel 36, a rotating shaft 37, a second angle adjustment frame 38 and at least one set of spray guns 39. The top of the hanger 31 and the outer wall of the hanger 31 on the side facing away from the spray gun 39 are fixedly connected with hanging ears for connecting and cooperating with the traveling assembly, so that the hanger 31 as a whole can be driven by the traveling assembly 20 to move and adjust the position. The first motor 33 and the second motor 34 are respectively installed and fixed on the inner top and inner bottom of the hanger 31. The output end of the second motor 34 is fixedly connected to one end of the worm 35, and the other end of the worm 35 rotates through the adjacent side of the first angle adjustment frame 32. The output end of the first motor 33 is fixedly connected to the adjacent side of the first angle adjustment frame 32, and the first angle adjustment frame 32 is movably arranged in the inner middle part of the hanger 31. The rotating shaft 37 is inserted in the middle of the first angle adjustment frame 32 and is rotatably connected thereto. The worm wheel 36 is sleeved on the outer wall of the rotating shaft 37 and is fixedly connected thereto. The worm wheel 36 and the worm 35 are meshed with each other. The second angle adjustment frame 38 is sleeved on the end of the rotating shaft 37 and is fixedly connected thereto on one side close to the rotating shaft 37. At least one group of spray guns 39 is installed on the second angle adjustment frame 38. When the output end of the second motor 34 drives the worm 35 to deflect, the meshing cooperation between the worm 35 and the worm wheel 36 is utilized so that the worm wheel 36 can use the rotating shaft 37 to drive the second angle adjustment frame 38 to deflect upward or downward in the longitudinal direction. When the output end of the first motor 33 drives the first angle adjustment frame 32 to deflect, the first angle adjustment frame 32 can use the rotating shaft 37 connected in the middle thereof to drive the second angle adjustment frame 38 to deflect to the left or right in the transverse direction. The spray gun 39 is connected with a hose that passes through the gap between the second angle adjustment frame 38 and the first angle adjustment frame 32, and the bottom end of the hose passes through the hanger 31. When the second angle adjustment frame 38 deflects and changes its direction, the spray gun 39 can change its direction accordingly, and at the same time use the hose to extract pomegranate sand and sandblast the workpiece.

[0022] In this embodiment, the number of sandblasting assemblies 30 is set to two groups, and the two groups of sandblasting assemblies 30 are symmetrically distributed so that the two groups of sandblasting assemblies 30 can perform sandblasting on opposite sides of the workpiece at the same time, thereby improving the processing efficiency.

[0023] In this embodiment, there is a gap between the second angle adjustment frame 38 and the first angle adjustment frame 32, and there is a gap between the second angle adjustment frame 38 and the adjacent side of the hanger 31 in the longitudinal direction, so that the second angle adjustment frame 38 has a moving space when the deflection action is performed. The spray gun 39 protrudes to the outside of the hanger 31, so that the spray gun 39 is not blocked or interfered when the shot peening is performed.

[0024] In this embodiment, the worm 35 is coaxially distributed with the output end of the first motor 33, and there is a gap between the end of the worm 35 close to the first motor 33 and the output end of the first motor 33, so that the longitudinal deflection or lateral deflection of the second angle adjustment frame 38 does not interfere with each other.

[0025] The system of the present invention may further include a control system for controlling the operation of the motor and the pneumatic cylinder to automatically move the position and adjust the sandblasting direction. It should be understood that the control system has no particular limitation and can be implemented by the control technology under the prior art, which will not be described in detail here.

[0026] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
