Description

Technical Field

[0001] This utility model relates to the technical field of sandblasting and rust removal equipment, and in particular to a sandblasting and rust removal device for the production of iron accessories. Background Technology

[0002] Iron fittings are widely used as basic structural components or connectors in fields such as machinery manufacturing, rail transportation, and infrastructure construction. Before being put into use or undergoing subsequent processes such as surface coating or electroplating, these iron fittings usually require surface pretreatment. Among them, sandblasting is a common and efficient surface cleaning method, which aims to remove oxide scale, rust, old coatings, and other adhering substances from the surface to obtain a clean surface with a certain degree of roughness, thereby enhancing the adhesion of subsequent coatings.

[0003] In current production practices, the method of sandblasting to remove rust from iron parts is usually quite primitive. The operator places the iron part on a simple workbench or the ground and uses a spray gun to sandblast one side of the workpiece. After one side is treated, the sandblasting operation needs to be paused, and the operator manually flips the iron part over to treat the other side.

[0004] This entirely manual flipping method has significant drawbacks. First, iron parts often have considerable weight and irregular shapes, making manual flipping not only physically demanding and inefficient, but also prone to bumps and knocks during handling and flipping, potentially posing safety hazards to operators. Second, manual flipping is highly unpredictable, making it difficult to ensure that the angle and position are precise each time. This can lead to some areas being repeatedly sandblasted or missed areas being sandblasted, resulting in uneven rust removal of the iron parts and affecting product quality. Furthermore, the entire process has a very low level of automation, severely limiting the improvement of production efficiency.

[0005] Therefore, this utility model proposes a sandblasting and rust removal device for the production of iron accessories to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems existing in the sandblasting and rust removal devices for iron accessories production, such as inconvenience in turning over during sandblasting and rust removal, low degree of automation leading to uneven rust removal, this utility model aims to provide a sandblasting and rust removal device for iron accessories production with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a sandblasting and rust removal device for the production of iron accessories, including: a workbench, and a clamping mechanism and a flipping mechanism disposed on the workbench.

[0008] The flipping mechanism is used to drive the clamping mechanism and the iron attachment it clamps to rotate, and the clamping mechanism is used to clamp the iron attachment to be derusted.

[0009] Furthermore, the flipping mechanism includes a rotating rod, and the clamping mechanism is fixedly connected to the rotating rod. The flipping mechanism drives the rotating rod to rotate, thereby realizing the flipping control of the clamping mechanism, so that the entire rust removal process does not require manual intervention to flip the surface, thus achieving automated operation.

[0010] Preferably, the flipping mechanism includes a cylinder, a rack, a gear, and a rotating rod. The gear is coaxially fixed on the rotating rod, and the rack meshes with the gear. The cylinder drives the rack to make linear motion. The linear motion is converted into the rotational motion of the rotating rod through the meshing transmission of the rack and gear. This transmission method has a simple structure, reliable operation, and can achieve precise angle control.

[0011] Preferably, the flipping mechanism further includes a first connecting block and a first fixed bracket. The output end of the cylinder is connected to the rack through the first connecting block. Both the first connecting block and the rack are slidably connected within the first fixed bracket, providing stable guidance and support for the linear movement of the rack, ensuring the smoothness of the transmission process, and preventing the rack from deflecting when subjected to force.

[0012] Preferably, the clamping mechanism includes a motor, a rotating shaft, a first connecting rod, a second connecting rod, a slider, and a clamp. The motor drives the rotating shaft to rotate, and the rotating shaft drives the slider to move linearly through a linkage mechanism composed of the first connecting rod and the second connecting rod. The clamp is fixed on the slider, thereby realizing automatic clamping and releasing of iron accessories and improving the efficiency of loading and unloading.

[0013] Preferably, the clamping mechanism includes two clamps, and two sets of linkage mechanisms consisting of the first linkage and the second linkage are symmetrically connected to the outer periphery of the rotating shaft, respectively driving the two sliders to realize the synchronous movement of the two clamps towards or away from each other. This symmetrical structure can complete the automatic centering and clamping of iron accessories of different sizes, ensuring the stability of the center of gravity of the workpiece during the flipping process.

[0014] Preferably, the clamping mechanism includes a second fixed bracket, on which the rotating rod and a mounting base for supporting the rotating rod are symmetrically arranged on both sides, forming a double support structure, which effectively resists the bending moment generated by the clamping mechanism and the workpiece gravity, and enhances the structural rigidity and stability of the clamping mechanism during the flipping process.

[0015] Preferably, the workbench has a slot, the position of which corresponds to the rotation path of the clamping mechanism, providing clearance for the clamping mechanism and the clamped iron attachment when flipping, preventing motion interference, and making the structural design more compact.

[0016] Preferably, the iron accessory production sandblasting and rust removal device further includes a spray gun and a sand storage tank. The spray gun is located on one side of the workbench and faces the clamping mechanism. The sand storage tank is connected to the spray gun through a pipeline and is used to perform sandblasting and rust removal operations, thus forming a complete automated sandblasting and rust removal system.

[0017] This utility model has the following beneficial effects:

[0018] 1. In this utility model, by setting up a clamping mechanism and a flipping mechanism, and fixing the clamping mechanism to the rotating part of the flipping mechanism, the problems of manual flipping, inconvenient operation, and low degree of automation required when sandblasting and rust removal of iron accessories in the prior art are solved. The technical effect of automatically clamping and flipping iron accessories is achieved, which significantly improves production efficiency and reduces the labor intensity of workers.

[0019] 2. In this utility model, the clamping mechanism is driven to flip by a cylinder to drive the rack to make linear motion, and the rack meshes with the gear fixed on the rotating rod. This solves the problems of complex flipping structure and unstable transmission, and achieves the technical effects of simple structure, stable and reliable transmission, and precise control of flipping angle. This ensures that the iron accessories can be flipped to the required position for comprehensive rust removal. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] Please refer to Figures 1 to 4 This utility model provides a sandblasting and rust removal device for the production of iron accessories, which aims to solve the problems of inconvenient turning and low automation leading to uneven rust removal when sandblasting and removing rust from iron accessories in the prior art.

[0028] like Figure 1 and Figure 2 As shown, the iron accessory production sandblasting and rust removal device includes a workbench 3, a clamping mechanism 5 and a flipping mechanism 4 disposed on the workbench 3. The clamping mechanism 5 is used to clamp the iron accessory to be rusted, and the flipping mechanism 4 is used to drive the clamping mechanism 5 and the iron accessory it clamps to rotate.

[0029] The flipping mechanism 4 includes a mounting base 406, a rotating rod 407, a gear 405, a rack 404, a cylinder 401, a first connecting block 402, and a first fixed bracket 403. The mounting base 406 is fixed on the workbench 3 to provide a stable mounting foundation for the rotating parts.

[0030] The clamping mechanism 5 includes a core frame structure, namely the second fixed bracket 501, which is fixedly connected to the rotating rod 407 of the flipping mechanism 4, so that the entire clamping mechanism 5 can be driven by the flipping mechanism 4. The rotating rod 407 is rotatably installed in the mounting base 406, realizing the rotational movement of the clamping mechanism 5 relative to the worktable 3.

[0031] To achieve the drive, gear 405 is coaxially fixed on rotating rod 407 and meshes with rack 404. Cylinder 401 serves as a power source, and its output end is connected to a first connecting block 402, which is fixedly connected to rack 404. The driving direction of cylinder 401 is parallel to the moving direction of rack 404. When cylinder 401 is activated, it drives rack 404 to make linear motion through first connecting block 402, and then the linear motion is converted into rotational motion of rotating rod 407 through gear 405.

[0032] To ensure the stability of the rack 404's movement, the first fixed bracket 403 is fixed on the worktable 3, and the first connecting block 402 and the rack 404 are both slidably connected within the first fixed bracket 403.

[0033] To improve the stability and load-bearing capacity of the structure, rotating rods 407 and mounting bases 406 are symmetrically arranged on both sides of the second fixed bracket 501 to ensure that the clamping mechanism 5 rotates smoothly without shaking.

[0034] The workbench 3 has a slot, the position of which corresponds to the rotation path of the clamping mechanism 5. This slot is used to provide clearance space for the clamping mechanism 5 and the iron accessories it clamps when they are flipped, so as to prevent interference.

[0035] The device also includes a spray gun 2 for performing sandblasting operations and a sand storage tank 1 for supplying abrasive. The spray gun 2 is located on one side of the workbench 3 and faces the clamping mechanism 5. The sand storage tank 1 is connected to the spray gun 2 through a pipeline.

[0036] To achieve automatic clamping of iron accessories, the clamping mechanism 5 has a complete drive transmission structure inside. Please refer to the following for details. Figure 3 and Figure 4 The clamping mechanism 5 includes a motor 504, a rotating shaft 505, a first connecting rod 506, a second connecting rod 507, a second connecting block 508, a slider 503, and a clamp 502. The motor 504 serves as the power source for the clamping action, is mounted on the second fixed bracket 501, and is used to drive the rotating shaft 505 to rotate.

[0037] The rotation of the rotating shaft 505 is converted into the linear motion of the clamp 502 through a linkage mechanism. Specifically, one end of the first linkage 506 is rotatably connected to the outer periphery of the rotating shaft 505, and the other end is rotatably connected to one end of the second linkage 507. The other end of the second linkage 507 is rotatably connected to the second connecting block 508.

[0038] The second connecting block 508 is fixedly connected to the slider 503 and is used to transmit the motion of the linkage mechanism to the slider 503. The slider 503 is slidably connected to the groove opened inside the second fixed bracket 501, thereby constraining the motion to a linear reciprocating motion along the groove direction.

[0039] The clamp 502 is fixedly connected to the slider 503. Therefore, when the motor 504 starts and drives the rotating shaft 505 to rotate, the second connecting block 508 and the slider 503 are driven to move linearly through the linkage mechanism composed of the first connecting rod 506 and the second connecting rod 507, thereby driving the clamp 502 to move.

[0040] In this embodiment, the clamping mechanism 5 includes two clamps 502. Two first connecting rods 506 are symmetrically rotatably connected to the outer periphery of the rotating shaft 505. The symmetrical connecting rod mechanism drives two sliders 503 respectively, thereby realizing that the two clamps 502 move towards or away from each other synchronously, ensuring that iron accessories of different sizes can be stably clamped in the center.

[0041] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0042] In a preferred embodiment, in order to achieve stable transmission between cylinder 401 and rack 404 in the flipping mechanism 4, the flipping mechanism 4 further includes a first connecting block 402, which is connected between the output end of cylinder 401 and rack 404, and directly and stably transmits the pushing and pulling force of cylinder 401 to rack 404.

[0043] As a further optimization of the above structure, in order to ensure the guiding accuracy of the rack 404 during the movement, the flipping mechanism 4 also includes a first fixed bracket 403, which is fixed on the worktable 3. The first connecting block 402 and the rack 404 are slidably connected in the first fixed bracket 403, thereby providing reliable support and guidance for the linear movement of the rack 404 and preventing it from deflecting or shaking when subjected to force.

[0044] In a preferred embodiment, in order to achieve reliable clamping of iron accessories, the clamping mechanism 5 includes two clamps 502, and two first connecting rods 506 are symmetrically connected to the outer periphery of the rotating shaft 505. This symmetrical layout allows the two clamps 502 to move synchronously towards or away from each other through two independent linkage mechanisms when the motor 504 drives the rotating shaft 505 to rotate, thereby achieving automatic centering and clamping of iron accessories.

[0045] As another preferred embodiment, in order to enhance the structural rigidity and stability of the entire clamping mechanism 5 during the flipping process, rotating rods 407 and mounting bases 406 are symmetrically arranged on both sides of the second fixed bracket 501. The rotating rods 407 on both sides jointly support the second fixed bracket 501, forming a double support structure, which effectively resists the bending moment generated by the clamping mechanism 5 and the workpiece gravity, and ensures the smoothness of the flipping action.

[0046] In a preferred embodiment, in order to provide sufficient space for the clamping mechanism 5 to rotate, a slot is provided in the worktable 3. The position of the slot corresponds to the rotation path of the clamping mechanism 5. When the clamping mechanism 5 and the iron attachment rotate, part of its structure can enter the slot, thus avoiding interference with the worktable 3 surface.

[0047] In a preferred embodiment, in order to complete the sandblasting and rust removal operation, the device also includes a spray gun 2 and a sand storage tank 1. The spray gun 2 is set on one side of the workbench 3 and faces the clamping mechanism 5, and is used to spray abrasive at high speed onto the surface of the iron attachment. The sand storage tank 1 is connected to the spray gun 2 through a pipeline and is used to store and supply abrasive such as sand particles to the spray gun 2.

[0048] Working principle: When working, the iron attachment is first placed between the two clamps 502 of the clamping mechanism 5. The motor 504 installed on the second fixed bracket 501 is started. The motor 504 drives the rotating shaft 505 to rotate. Since the outer circumference of the rotating shaft 505 is symmetrically connected to the first connecting rod 506, the other end of the first connecting rod 506 is rotatably connected to the second connecting rod 507, and the other end of the second connecting rod 507 is rotatably connected to the second connecting block 508 fixed on the slider 503, the rotation of the rotating shaft 505, through the linkage of the linkage mechanism, ultimately drives the slider 503 to move towards each other along the groove in the second fixed bracket 501, thereby driving the two clamps 502 fixed on the slider 503 to clamp the iron attachment synchronously.

[0049] After clamping is completed, the spray gun 2 is turned on. The sand particles in the sand storage tank 1 are transported to the spray gun 2 through the pipeline and sprayed at high speed onto the exposed surface of the iron accessory to complete the sandblasting and rust removal on one side. Then, the cylinder 401 in the flipping mechanism 4 is started. The cylinder 401 drives the rack 404 to make linear motion in the first fixed bracket 403 through the first connecting block 402. Since the rack 404 meshes with the gear 405 coaxially fixed on the rotating rod 407, the linear motion of the rack 404 is converted into the rotational motion of the gear 405, which in turn drives the rotating rod 407 to rotate in the mounting base 406.

[0050] Since the second fixed bracket 501 of the clamping mechanism 5 is fixedly connected to the rotating rod 407, the rotation of the rotating rod 407 drives the entire clamping mechanism 5, along with the iron attachment it clamps, to flip. The slots on the worktable 3 provide clearance for the flipping process. After flipping to a predetermined angle, the spray gun 2 can sandblast and remove rust from the other side of the iron attachment. Through this automated collaborative work of clamping and flipping, the problems of inconvenience and inaccurate positioning of manual flipping in the prior art are solved, ensuring that all surfaces of the iron attachment are uniformly and comprehensively sandblasted, thus improving the rust removal quality and production efficiency.
