Description

Technical Field

[0001] The present invention relates to the technical field of workpiece conveying, and particularly to a workpiece conveying device for a shot blasting machine. Background Art

[0002] To ensure the cleanliness of the workpiece surface, remove contaminants and oxide layers, provide good coating adhesion, and adjust the surface roughness, the workpiece is usually subjected to surface shot blasting treatment. Before the shot-blasted workpiece is conveyed to the next process, the debris remaining on its surface needs to be cleaned to ensure the subsequent processing effect.

[0003] In the prior art, as disclosed in the Chinese patent with the publication number CN219685132U, there is provided a blanking mechanism for a shot blasting machine, which includes a first conveying device. A shot blasting chamber for processing the workpiece is provided on the conveying path of the first conveying device. A flipping assembly is provided at the output end of the first conveying device, and a second conveying device is provided on the other side of the flipping assembly. The second conveying device and the first conveying device are arranged at different heights. In the blanking mechanism for a shot blasting machine of this patent, through the provided flipping assembly, the workpiece carrying debris leaving the shot blasting chamber is flipped, so that the debris carried by the workpiece is thrown off during the rotation process, thus eliminating the need for manual cleaning and facilitating the workpiece to enter the next process for further processing.

[0004] In the above technical solution, when cleaning the debris on the workpiece surface, the debris is thrown off by flipping the workpiece. However, irregular surfaces (such as grooves, holes, gaps, etc.) may cause debris to accumulate in dead corners, and it is difficult to completely remove the debris only by flipping. The metal debris after shot blasting may be electrostatically adsorbed on the workpiece surface and cannot fall off naturally by gravity during flipping, affecting the cleaning effect of the workpiece surface.

[0005] Based on this, a workpiece conveying device for a shot blasting machine is proposed. Summary of the Invention

[0006] In order to solve the above technical problems, the present invention proposes a workpiece conveying device for a shot blasting machine.

[0007] The technical solution for achieving the object of the present invention is as follows: A workpiece conveying device for a shot blasting machine includes a base, and a housing and a shot blasting chamber are respectively fixedly connected to the upper surface of the base. The device further includes:

[0008] A cleaning assembly, which includes an adaptive cleaning unit, a vibration cleaning unit, and a blast cleaning unit;

[0009] The adaptive cleaning unit includes two cylinders. The inner top walls of the two cylinders are both fixedly connected with springs. The inner walls of the two cylinders are both slidably connected with piston rods. The bottom ends of the two springs are respectively fixedly connected with the top ends of the corresponding two piston rods. The bottom ends of the two piston rods are both fixedly connected with hooks. The surfaces of the two cylinders are fixedly communicated with the same connecting pipe. The surface of the connecting pipe is fixedly communicated with an air inlet pipe;

[0010] The vibration cleaning unit includes connecting rods fixed on the surfaces of the two piston rods. The surface of the connecting rod is fixedly connected with a fixed frame. The inner wall of the fixed frame is fixedly connected with a U-shaped ball rod. The inner walls of the two sides of the housing are respectively fixedly connected with a first fixing plate and a second fixing plate. The upper surfaces of the first fixing plate and the second fixing plate are both fixedly connected with convex blocks.

[0011] Preferably, a sealing plate is rotatably arranged on the inner wall of the air inlet pipe. A first rotating rod is fixedly connected to the surface of the sealing plate. A first gear is fixedly connected to one end of the first rotating rod. A right-angle rack is fixedly connected to the inner wall of one side of the housing.

[0012] Preferably, the air-blowing cleaning unit includes air-blowing pipes fixedly communicated with the surfaces of the two cylinders. The bottom ends of the two air-blowing pipes are both fixedly communicated with hoses. The surfaces of the two air-blowing pipes are both fixedly connected with rotating seats. The inner walls of the two rotating seats are respectively rotatably connected with a first air hood and a second air hood. The upper surfaces of the first air hood and the second air hood are respectively fixedly communicated with the bottom ends of the corresponding two hoses.

[0013] Preferably, check valves are fixedly installed on the surfaces of the two air-blowing pipes and the air inlet pipe. A second rotating rod is fixedly connected to one end of each of the first air hood and the second air hood. A second gear is fixedly connected to one end of each of the two second rotating rods.

[0014] Preferably, a first cross plate and a second cross plate are respectively fixedly connected to the two sides of the housing. A plurality of driving racks two are fixedly connected to the upper surfaces of the first cross plate and the second cross plate. A plurality of driving racks one are fixedly connected to the lower surfaces of the first fixing plate and the second fixing plate.

[0015] Preferably, an electric drive track is fixedly installed on the inner top wall of the housing. A sliding plate is slidably installed on the surface of the electric drive track in a matching manner. The lower surface of the sliding plate is respectively fixedly connected with the upper surfaces of the corresponding two cylinders.

[0016] Preferably, a shot blasting machine is fixedly installed on the upper surface of the shot blasting chamber. A shot peening device is fixedly installed inside the shot blasting chamber. The shot peening device is fixedly communicated with the shot blasting machine through a pipeline.

[0017] Preferably, a controller is fixedly installed on one side of the shot blasting chamber.

[0018] Compared with the prior art, the remarkable advantages of the present invention are:

[0019] First: When the first gear meshes with the right-angle rack, the first gear rotates, opening the air path of the intake pipe. At this time, the piston rods inside the two cylinders slide downward under the weight of the workpiece below the hook, stretching the springs. When the piston rods descend, they drive the connecting rods, fixed frames, and U-shaped ball rods arranged on their surfaces to descend synchronously. After the U-shaped ball rods descend, during the continuous transportation on the electric drive track, they will continuously reciprocally press against the bumps on the first fixed plate and the second fixed plate, thereby forming the piston rods driving the hooks to reciprocally vibrate up and down, so that the workpieces hung on the hooks can be vibration-cleaned of debris;

[0020] Second: The spring arranged inside the cylinder of the present invention can adaptively adjust the amplitude according to the weight of the workpiece, improving the vibration cleaning effect. When the workpiece is heavier, the spring is stretched longer. At this time, the U-shaped ball rods descend a greater distance, so the amplitude during the extrusion vibration with the bumps is greater. When the workpiece is lighter, on the contrary, the amplitude is smaller. The adaptive adjustment of the amplitude according to the weight can avoid the problem that the workpiece falls off the hook due to the mismatch between the workpiece quality and the amplitude, thus affecting the transportation effect of the workpiece;

[0021] Third: During the process that the electric drive track drives the sliding plate to transport and the U-shaped ball rods drive the piston rods to reciprocally vibrate, the reciprocating sliding of the piston rods inside the cylinders can, through the action of the air blowing pipe, flexible pipe, air hood, intake pipe, and one-way valve, inhale the gas through the intake pipe, then blow it out through the air blowing pipe, and finally blow it out through the air hood, which can blow the workpiece to further improve the cleaning effect;

[0022] Fourth: The second gears arranged at one ends of the first air hood and the second air hood can respectively reciprocally mesh with a plurality of driving racks one arranged on the first fixed plate, the first cross plate, the second fixed plate, and the second cross plate, so as to realize the second gears respectively driving the first air hood and the second air hood to reciprocally rotate, which can increase the air blowing range, thereby further improving the cleaning effect on the workpiece.

[0035] The present invention will be described in detail below. The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] The present invention provides a workpiece conveying device for a shot blasting machine through improvement. The technical solution of the present invention is as follows:

[0037] As Figures 1-9 shown, a workpiece conveying device for a shot blasting machine 4 includes a base 1. The upper surface of the base 1 is fixedly connected with a housing 2 and a shot blasting chamber 36 respectively. The housing 2 can provide protection during the conveying process. It further includes:

[0038] Cleaning component, the cleaning component includes an adaptive cleaning unit, a vibration cleaning unit and a blast cleaning unit;

[0039] The adaptive cleaning unit includes two cylinders 14. The inner top walls of the two cylinders 14 are fixedly connected with springs 15. The inner walls of the two cylinders 14 are slidably connected with piston rods 16. By setting the springs 15, the piston rods 16 can drive the hooks 35 to vibrate, so as to achieve cleaning. The stretching degree of the springs 15 can be adjusted adaptively according to the weight of the workpiece. The bottom ends of the two springs 15 are respectively fixedly connected with the top ends of the corresponding two piston rods 16. The bottom ends of the two piston rods 16 are both fixedly connected with hooks 35. The surfaces of the two cylinders 14 are fixedly communicated with the same connecting pipe 13. The surface of the connecting pipe 13 is fixedly communicated with an air inlet pipe 21. An air filter element is arranged inside the air inlet pipe 21, which can filter during the air intake process;

[0040] The vibration cleaning unit includes a connecting rod 17 fixed on the surfaces of the two piston rods 16. A fixing frame 20 is fixedly connected to the surface of the connecting rod 17. A U-shaped ball rod 12 is fixedly connected to the inner wall of the fixing frame 20. The U-shaped ball rod 12 can be in contact with the convex blocks 11 on both sides of the housing 2 at the same time, so as to form a vibration effect and improve the stability of vibration. Fixed plates one 9 and two 10 are respectively fixedly connected to the inner walls on both sides of the housing 2. Convex blocks 11 are fixedly connected to the upper surfaces of the fixed plates one 9 and two 10. The convex blocks 11 are arranged in a triangular shape, which can adapt to the reset after transportation.

[0041] Such as Figure 3 and Figure 6 As shown, a sealing plate 23 is rotatably arranged on the inner wall of the air inlet pipe 21. A rotating rod one 24 is fixedly connected to the surface of the sealing plate 23. One end of the rotating rod one 24 is fixedly connected to a gear one 25. A right-angle rack 8 is fixedly connected to the inner wall of one side of the housing 2. By setting the sealing plate 23, the air path of the air inlet pipe 21 can be opened and closed. The right-angle rack 8 can rotate the gear one 25, and then drive the rotation of the sealing plate 23. A rubber sealing ring is arranged on the edge of the sealing plate 23, which can improve the fitting degree with the inner wall of the air inlet pipe 21, so as to improve the airtightness.

[0042] Such as Figure 4 and Figure 5As shown in the figure, the air-blowing cleaning unit includes an air-blowing pipe 18 fixedly connected to the surfaces of two cylinders 14. Hoses 30 are fixedly connected to the bottoms of both air-blowing pipes 18. The hoses 30 can provide movement compensation for the first air hood 28 and the second air hood 29 during rotation. Rotating seats 19 are fixedly connected to the surfaces of both air-blowing pipes 18. The first air hood 28 and the second air hood 29 are respectively rotatably connected to the inner walls of the two rotating seats 19. The first air hood 28 and the second air hood 29 can increase the air-blowing range, thereby improving the cleaning effect of the workpiece. The upper surfaces of the first air hood 28 and the second air hood 29 are respectively fixedly connected to the bottoms of the corresponding two hoses 30.

[0043] Check valves 22 are fixedly installed on the surfaces of both air-blowing pipes 18 and the intake pipe 21. The check valve 22 is a prior art and can achieve one-way air flow in the air path. One end of each of the first air hood 28 and the second air hood 29 is fixedly connected to a second rotating rod 32, and a second gear 33 is fixedly connected to one end of each of the two second rotating rods 32.

[0044] As Figure 8 and Figure 9 As shown in the figure, a first cross plate 26 and a second cross plate 27 are respectively fixedly connected to both sides of the housing 2. A plurality of second driving racks 34 are fixedly connected to the upper surfaces of the first cross plate 26 and the second cross plate 27. A plurality of first driving racks 31 are fixedly connected to the lower surfaces of the first fixing plate 9 and the second fixing plate 10. The first driving racks 31 and the second driving racks 34 are arranged facing each other, so that when the second gear 33 moves and meshes with the first driving racks 31 and the second driving racks 34, the forward and reverse rotations of the second gear 33 can be realized, thereby realizing the swinging of the first air hood 28 and the second air hood 29.

[0045] An electric drive rail 5 is fixedly installed on the inner top wall of the housing 2. A sliding plate 7 is slidably installed on the surface of the electric drive rail 5 in a matching manner. The lower surface of the sliding plate 7 is fixedly connected to the upper surfaces of the corresponding two cylinders 14.

[0046] A shot blasting machine 4 is fixedly installed on the upper surface of the shot blasting chamber 36. A shot peening device 6 is fixedly installed inside the shot blasting chamber 36. The shot peening device 6 is fixedly connected to the shot blasting machine 4 through a pipeline.

[0047] A controller 3 is fixedly installed on one side of the shot blasting chamber 36.

[0048] The specific working method is as follows: During use, the workpiece to be shot blasted and cleaned is hung at the hook 35. Then, the electric drive rail 5 drives the sliding plate 7 to slide. When it is transported into the shot blasting chamber 36, the shot blasting machine 4 and the shot peening device 6 provided can perform shot blasting cleaning on the surface of the workpiece. The cleaned workpiece continues to be transported through the electric drive rail 5.

[0049] When the first gear 25 meshes with the right-angle rack 8, the first gear 25 rotates, opening the air path of the air inlet pipe 21. At this time, the piston rods 16 inside the two cylinders 14 slide downward under the weight of the workpiece below the hook 35, stretching the spring 15. When the piston rod 16 descends, it drives the connecting rod 17, the fixed bracket 20, and the U-shaped ball rod 12 arranged on its surface to descend synchronously. After the U-shaped ball rod 12 descends, during the continuous transportation of the electric drive track 5, it will continuously reciprocally squeeze the bumps 11 on the first fixing plate 9 and the second fixing plate 10, thereby forming the piston rod 16 driving the hook 35 to reciprocally vibrate up and down, so as to vibrate and clean the debris on the workpiece hung on the hook 35;

[0050] Through the spring 15 arranged inside the cylinder 14, the amplitude can be adaptively adjusted according to the weight of the workpiece, improving the vibration cleaning effect. When the weight of the workpiece is large, the spring 15 is stretched longer. At this time, the U-shaped ball rod 12 descends a greater distance, so the amplitude of vibration when squeezing and vibrating with the bump 11 is larger. When the mass of the workpiece is small, on the contrary, the amplitude is smaller. The adaptive adjustment of the amplitude according to the weight can avoid the problem that the workpiece falls off the hook 35 due to the mismatch between the workpiece mass and the amplitude, thus affecting the transportation effect of the workpiece;

[0051] During the process of the electric drive track 5 driving the sliding plate 7 to transport and realizing the reciprocating vibration of the U-shaped ball rod 12 driving the piston rod 16, the reciprocating sliding of the piston rod 16 inside the cylinder 14 can, through the action of the air blowing pipe 18, the hose 30, the air hood, the air inlet pipe 21, and the one-way valve 22, suck the gas through the air inlet pipe 21, then blow it out through the air blowing pipe 18, and finally blow it out through the air hood, so as to blow and clean the workpiece, further improving the cleaning effect; At the same time, during the movement, the second gears 33 arranged at one ends of the first air hood 28 and the second air hood 29 can respectively reciprocally mesh with a plurality of driving racks 31 and a plurality of driving racks 34 arranged on the first fixing plate 9, the first cross plate 26, the second fixing plate 10, and the second cross plate 27, so as to realize the two second gears 33 respectively driving the first air hood 28 and the second air hood 29 to rotate reciprocally, which can increase the air blowing range, thereby further improving the cleaning effect on the workpiece;

[0052] After the transportation is completed and the workpiece is unloaded, the spring 15 drives the piston rod 16 to reset, and the sliding plate 7 is synchronously reset under the action of the electric drive track 5.

[0053] The technical means disclosed in the solution of the present invention are not limited to the technical means disclosed by the above technical means, but also include the technical solutions composed of the equivalent replacements of the above technical features. The matters not covered in the present invention belong to the common general knowledge of those skilled in the art.
