Technical Field

[0001] This utility model relates to the field of shot peening technology, specifically to a shot peening device. Background Technology

[0002] A shot peening machine is an industrial device that uses high-speed shot to impact a metal surface, causing it to undergo elasto-plastic deformation and generate residual compressive stress, thereby improving the fatigue strength and stress corrosion resistance of the workpiece. This technology is widely used in many industrial fields such as aerospace, automotive, locomotive, and power energy.

[0003] In existing technologies, shot peening typically employs either a moving shot peening gun or a moving workpiece. This method often results in incomplete surface treatment of the product, and the increased processing time to achieve complete surface treatment leads to low efficiency. Therefore, there is an urgent need for shot peening equipment that improves processing efficiency while ensuring processing quality. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a shot peening device in which both the shot peening gun and the workpiece to be treated can move, avoiding dead angles, ensuring the treatment effect, and improving the treatment quality.

[0005] Specifically, this utility model discloses a shot peening device, including:

[0006] The shot peening chamber has a shot peening cavity inside.

[0007] A shot peening device has a shot peening gun disposed in a shot peening chamber, and the shot peening gun is connected to a moving module and a rotating module;

[0008] A workpiece fixing device includes a rotating table, on which a fixing column for fixing the workpiece is provided, and the fixing column is rotatable;

[0009] A shot peening generator is connected to the shot peening gun;

[0010] The shot peening collection device connects the shot peening chamber and the shot peening generator, allowing the shot to be recycled.

[0011] The advantages of adopting the above technical solution are that it enables automatic shot peening. By setting up a rotatable workpiece fixing device and a movable shot peening generator, the workpiece is processed without dead angles, ensuring processing quality and improving product processing efficiency.

[0012] Furthermore, the shot peening device includes a mounting frame and a rotating shaft. The rotating module is mounted on the mounting frame and connected to the rotating shaft. The moving module includes a vertical moving module and a horizontal moving module. The vertical moving module is mounted on the mounting frame and drives the rotating module and the rotating shaft to move vertically. The horizontal moving module is located at the top of the shot peening chamber and drives the mounting frame to move.

[0013] The advantages of adopting the above technical solution are that a rotating shaft is set to drive the shot peening gun to swing, which is suitable for different usage needs. At the same time, a vertical movement module and a horizontal movement module are set so that the shot peening gun can move horizontally and vertically. The shot peening gun has multiple degrees of freedom in multiple directions to ensure the usage needs.

[0014] Furthermore, a rotating plate is connected to the bottom of the rotating shaft, and a horizontally arranged connecting shaft is provided between the rotating plate and the rotating shaft. The rotating plate swings around the connecting shaft. The rotating plate is provided with multiple strip-shaped holes. The shot peening gun is provided with a connecting block. The connecting block is connected to the rotating plate through a connector, which passes through the strip-shaped holes.

[0015] The advantage of adopting the above technical solution is that the rotating plate is used to install the shot peening gun, and the slotted hole and connecting block allow the position and angle of the shot peening gun to be adjusted to suit different application situations.

[0016] Furthermore, a protective plate is provided on the side of the rotating plate, and the protective plate is provided with a plurality of protrusion holes for the end of the shot peening gun to pass through.

[0017] The advantage of adopting the above technical solution is that the protective plate plays a protective role, preventing high-speed shot from colliding with the shot blasting gun.

[0018] Furthermore, the rotating platforms are symmetrically arranged and connected to a rotating drive assembly. The rotating drive assembly is located on the shot peening chamber and is connected to a rotating door. The rotating platforms are located on both sides of the rotating door.

[0019] The advantage of adopting the above technical solution is that while one side of the symmetrically arranged rotary table is being processed in the shot peening chamber, the other side rotates to the outside. The one rotating to the outside can be used for loading or unloading operations, while the one inside can rotate directly after completing the processing, without waiting time, thus improving processing efficiency.

[0020] Furthermore, there are multiple fixed columns, with a workpiece placement platform at the top and a driven gear connected to the bottom. The rotating table is equipped with a driving gear, which meshes with the driven gear to drive the driven gear to rotate.

[0021] The advantage of adopting the above technical solution is that the workpiece is fixed by the workpiece placement table and then rotated by gears. During the processing, all parts of the workpiece can receive the shot from the shot blasting gun, so that there are no dead corners in the surface treatment of the workpiece.

[0022] Furthermore, the bottom of the shot peening chamber is provided with a shot collection trough, and the shot collection device includes a screw conveyor device disposed in the shot collection trough. The screw conveyor device is connected to a lifting device, the lifting device is connected to a vibrating screen, the vibrating screen is connected to a storage chamber, the bottom of the storage chamber is provided with a discharge pipe, and the discharge pipe is provided with a valve.

[0023] The advantage of adopting the above technical solution is that the sprayed shot is collected by the shot collection trough, then conveyed by the screw conveyor, and then lifted by the lifting device into the vibrating screen. The shot is separated by the vibrating screen and then stored in the storage bin in the machine to await feeding, realizing the recycling of shot and reducing production costs.

[0024] Furthermore, the shot peening device includes a storage tank and a shot peening tank. The storage tank is connected to the shot peening tank, the top of the storage tank is connected to the discharge pipe, the shot peening tank is connected to the shot peening gun through a shot peening pipe, and the shot peening pipe and the shot peening tank are connected to a gas tank.

[0025] The advantage of adopting the above technical solution is that the shot enters the shot peening tank through the storage tank, and then enters the shot peening gun through the shot peening pipe and is sprayed out. The whole process is provided with high-pressure gas through the gas pipe, so that the shot is discharged evenly and accelerated, and the workpiece surface is uniformly impacted.

[0026] Furthermore, an auxiliary gear is provided between the driven gears, and the auxiliary gear is rotatably mounted.

[0027] The advantage of adopting the above technical solution is that the auxiliary gears enable all fixed columns to rotate in the same direction and rotate stably without jamming, ensuring that multiple workpieces are processed evenly during the process and guaranteeing the surface treatment quality.

[0028] Furthermore, a protective tube is provided on the outside of the rotating shaft.

Detailed Implementation

[0040] The present invention will now be described in further detail with reference to the accompanying drawings.

[0041] like Figure 1-7 As shown, this utility model discloses a shot peening device, comprising:

[0042] The shot peening chamber 1 has a shot peening chamber 15 inside, which is connected to a dust collector. The shot peening chamber 1 has a door that can be opened and closed, allowing personnel to enter the interior through the door.

[0043] The shot peening device has a shot peening gun 2 disposed in the shot peening chamber 15, and the shot peening gun 2 is connected to a moving module 3 and a rotating module 4.

[0044] A workpiece fixing device includes a rotating table 5, on which a fixing column 6 for fixing the workpiece is provided, and the fixing column 6 is rotatable;

[0045] The shot peening device 7 is connected to the shot peening gun 2;

[0046] The shot peening collection device 8 is connected to the shot peening chamber 15 and the shot peening generating device 7, so that the shot can be recycled.

[0047] The advantages of adopting the above technical solution are that it realizes automatic shot peening. By setting a rotatable workpiece fixing device and a movable shot peening generating device 7, the workpiece is processed without dead angles, ensuring processing quality, improving product processing efficiency, and making it suitable for large-scale mass production.

[0048] In some implementation schemes, such as Figure 2-3 As shown, the shot peening device includes a mounting frame 9 and a rotating shaft 91. The rotating module 4 is mounted on the mounting frame 9 and connected to the rotating shaft 91. The rotating module 4 is a motor module connected to the rotating shaft 91 to drive the rotating shaft 91 to rotate. A protective tube is provided on the outside of the rotating shaft 91. The protective tube is fixedly installed and does not rotate with the rotating shaft 91.

[0049] The moving module 3 includes a vertical moving module 31 and a horizontal moving module 32. The vertical moving module 31 is mounted on the mounting frame 9 and drives the rotating module 4 and the rotating shaft 91 to move vertically. The horizontal moving module 32 is located at the top of the shot peening chamber 1 and drives the mounting frame 9 to move. The vertical moving module 31 and the horizontal moving module 32 are made of a screw motor module. The screw is connected to a moving block. The rotating module 4 is mounted on the moving block, so that the rotating module 4 moves vertically with the moving block. The mounting frame 9 is also provided with a vertically set guide rail, and the moving block slides along the guide rail.

[0050] A horizontal guide rail is installed on the upper surface of the shot peening chamber 1. The horizontal moving module 32 can also be a screw motor module to drive the mounting frame 9 to move horizontally. The mounting frame 9 moves along the horizontal guide rail toward or away from the product. A movable sealing plate is also provided at the top of the shot peening chamber. As the mounting frame 9 moves, the shot peening chamber 1 is always a closed chamber to prevent the leakage of shot generated during shot peening.

[0051] In some implementations, a rotating plate 92 is connected to the bottom of the rotating shaft 91, and a horizontally arranged connecting shaft 93 is provided between the rotating plate 92 and the rotating shaft 91. The rotating plate 92 and the connecting shaft 93 are fixedly connected. A bevel gear deflector is installed between the rotating shaft 91 and the connecting shaft 93. The bevel gear deflector connects the rotating shaft 91 and the connecting shaft 93. The rotation of the vertically oriented rotating shaft 91 is converted into the rotation of the horizontally oriented connecting shaft 93. The rotating plate 92 swings around the connecting shaft 93. The rotating plate 92 is provided with multiple slotted holes 94. A connecting block 21 is fixedly installed in the middle of the shot peening gun 2. The connecting block 21 is connected to the rotating plate 92 through a connector, which is a screw. A threaded hole is provided on the top of the connecting block 21. The screw passes through the slotted holes 94 and is locked, which is convenient for installation. At the same time, the angle of the shot peening gun 2 can be adjusted, and there are multiple guns, which can ensure that all surfaces of the workpiece are treated during the process. The shot peening gun 2 swings continuously from top to bottom and then from top to bottom towards the product, which is coordinated with the automatic rotation of the workpiece and is suitable for the treatment of various types of workpieces.

[0052] Furthermore, a protective plate 95 is provided on the side of the rotating plate 92. The protective plate 95 is fixedly installed on the side of the rotating plate 92, close to the fixed position of the workpiece. The protective plate 95 is provided with multiple protrusion holes for the end of the shot peening gun 2 to pass through. The shot peening gun 2 is located outside the protective plate 95, and the end for shot discharge protrudes from the protrusion holes, which can effectively prevent the main body of the shot peening gun 2 from being impacted and extend the service life of the shot peening gun 2.

[0053] In some implementations, the rotary tables 5 are symmetrically arranged and connected to a rotary drive assembly 51. The rotary drive assembly 51 is located on the shot peening chamber 1 and is connected to a rotating door 52. The rotary tables 5 are located on both sides of the rotating door 52. The rotary drive assembly includes a rotating shaft and a motor connected to the rotating shaft. The motor is located on the top of the shot peening chamber 1. The rotating door 52 is connected to the rotating shaft, which drives the rotating door 52 to rotate. Since the rotary tables 5 are symmetrically arranged on both sides of the rotating door 52 and are fixedly installed with the rotating door 52, and the rotating door 52 is also provided with reinforcing plates on both sides to withstand the impact of the shot, the rotating door 52 is always closed during the processing. While the workpieces inside the shot peening chamber 1 are being processed, the rotary tables 5 on the outside can be loaded or unloaded. After the workpieces inside are processed, they can be rotated directly to continue processing without waiting time, thus improving processing efficiency.

[0054] Furthermore, such as Figure 4As shown, there are multiple fixed columns 6, with a workpiece placement platform 61 fixedly installed on the top. The bottom of the fixed columns 6 is fixedly connected to the driven gears 62. As the driven gears rotate, multiple driven gears 62 are rotatably installed on the lower surface of the rotary table 5. A driving gear 64 is installed on the lower surface of the rotary table 5. The driving gear 64 meshes with the driven gears 62, driving the driven gears 62 to rotate. The driving gear 64 is connected to a motor drive. An auxiliary gear 63 is provided between each driven gear 62 and meshes with the driven gears. The auxiliary gears 63 are rotatably installed on the lower side of the rotary table 5. Multiple auxiliary gears 63 are the same size, so that the multiple workpiece placement platforms 61 rotate in the same direction and at the same speed. A protective plate 95 is provided at the bottom of the rotary table 5 to prevent shot and impurities from entering the meshing gears.

[0055] In some implementation schemes, such as Figure 5-6 As shown, the bottom of the shot peening chamber 1 is provided with a shot collection trough. The shot collection device includes a screw conveyor 11 installed in the shot collection trough. The screw conveyor 11 is connected to a lifting device 12. The lifting device 12 is connected to a vibrating screen 13. The vibrating screen 13 is connected to a storage chamber 14. The bottom of the storage chamber 14 is provided with a discharge pipe and a valve.

[0056] The screw conveyor 11 includes a rotating shaft 111 with helical blades 112 mounted on it. The rotating shaft 111 extends into a shot collection trough, and a transition trough 113 is located at the other end. The helical blades 112 convey the shot into the transition trough 113. A flat blade 114 is mounted on the rotating shaft 111 within the transition trough 113. Rotation of the flat blade pushes the shot in the transition trough 113 to the bottom of a lifting device 12 located on the side. The lifting device 12 has a circulating hopper 115 that lifts the shot. The shot enters a pipe connected to a vibrating screen 13 and then into the vibrating screen. The vibrating screen 13 separates the shot by size, and shot that meets the size requirements is stored in a storage bin 14. Finally, the shot enters the shot peening generator 7, achieving shot recycling and reducing production costs. The vibrating screen 13 and the lifting device 12 are existing technologies and will not be described further here.

[0057] In some implementations, the shot peening generating device 7 includes a storage tank 71 and a shot peening tank 72. The storage tank 71 is connected to the shot peening tank 72, and the top of the storage tank 71 is connected to the discharge pipe. The shot peening tank 72 is connected to the shot peening gun 2 through a shot peening pipe. The shot peening pipe, the storage tank 71, and the shot peening tank 72 are connected to a gas tank. The shot peening tank 72 and the storage tank 71 are equipped with level gauges, pressure gauges, etc., to replenish the material in time when it is insufficient. At the same time, multiple shot peening pipes can be set at the bottom of the shot peening tank 72 to connect multiple shot peening guns 2 to realize the shot peening action.

[0058] The working process begins with the workpiece being fixed onto the workpiece placement platform 61 manually or by a robotic arm. Then, the equipment is started, and the rotating table 5 rotates, transferring the loaded workpiece into the shot peening chamber 15. The shot peening gun 2 moves under the control of the equipment. Once in position, the switch at the bottom of the shot peening tank 72 opens, allowing the shot to enter the shot peening pipe and accelerate, initiating the shot peening process. During shot peening, the shot peening gun 2 can move and swing, while the workpiece placement platform 61 rotates around the axis of the fixed column 6, ensuring complete surface treatment of the workpiece and high processing efficiency. Simultaneously, a dust collector operates during the process to prevent dust overflow, and the blasted shot falls into the shot collection container. Inside the trough, the material is transported to the vibrating screen 13 at the top via a screw conveyor 11 and a lifting device. The material is then screened by the vibrating screen 13 and enters the shot storage bin 14. After being stored in the shot storage bin 14, the material enters the storage tank 71 and finally enters the shot peening tank 72 to achieve the recycling of shot. This equipment is equipped with a shot peening gun 2 with translational and swing degrees of freedom, which, together with a rotatable workpiece, ensures complete surface treatment of the workpiece without dead angles. At the same time, it is equipped with a double rotary table 5 to realize the simultaneous loading and unloading and shot peening processing, which effectively improves the overall processing efficiency, reduces labor costs, and is suitable for large-scale production.

[0059] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
