Description

Technical Field

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

[0002] With the rapid development of modern industrial technology, machinery has gradually replaced manual labor, and robots have gradually entered major factories for industrial production. Truss structures have advantages such as strong load-bearing capacity, simple manufacturing and installation, and wide range of applications. When combined with shot peening, they can complete a series of high-difficulty shot peening tasks. However, existing truss structures occupy a lot of space and are not stable enough during movement. Therefore, we need to develop a shot peening device with a stable walking structure that is suitable for processing large products. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a truss shot peening device with stable structure, small footprint, long stroke, suitable for processing various types of products, long service life, and can ensure precision.

[0004] Specifically, this utility model discloses a truss shot peening device, comprising:

[0005] A mobile frame on which shot peening components are mounted;

[0006] A horizontal moving device, fixed to a wall or bracket, includes a walking component, a track device, and a horizontal drive component. The walking component is connected to the moving frame, and the horizontal drive component drives the walking component to move along the track device.

[0007] A vertical moving device includes multiple vertical tracks and a vertical driving device. The vertical tracks are arranged on the moving frame, and the vertical driving device drives the shot peening assembly to move along the vertical tracks.

[0008] The advantages of adopting the above technical solution are that the horizontal and vertical moving devices drive the shot peening components to move horizontally and vertically, resulting in a stable structure, small footprint, and applicability to the processing of products of various sizes.

[0009] Furthermore, the walking assembly includes: a mounting plate, a walking wheel set, and an auxiliary wheel set. The walking wheel set includes a plurality of walking wheels rotatably mounted on the mounting plate, and the walking wheels move along the track device. The auxiliary wheel set includes auxiliary wheels symmetrically arranged on both sides of the walking wheels, and the auxiliary wheels move along both sides of the track device.

[0010] The advantage of adopting the above technical solution is that the walking wheel set bears the weight of the entire mobile frame and shot peening assembly, making the shot peening assembly move smoothly. The auxiliary wheel set plays an auxiliary role, ensuring that the mobile frame moves smoothly, stably and without deviation.

[0011] Furthermore, the walking wheels are symmetrically and inclined, and the track device includes a horizontal track with an inclined surface for the walking wheels to roll.

[0012] The advantage of adopting the above technical solution is that the inclined walking wheels and their matching inclined surfaces play a good limiting role, ensuring that the walking wheels move along the track. Under the action of gravity, the walking wheels move along the inclined surfaces, effectively preventing the mobile frame from displacing in the vertical walking direction and ensuring the moving accuracy of the mobile frame.

[0013] Furthermore, the walking assembly also has a cleaning device, including an air outlet block and jet nozzles installed on both sides of the air outlet block. Both the air outlet block and the jet nozzles are connected to an air source and are provided with multiple air outlets facing the track device.

[0014] The advantages of adopting the above technical solution are that the cleaning device is set up to blow air to remove the shot falling on the walking component, ensure the smooth movement of the moving frame, prevent the walking component from slipping and other problems, effectively extend the service life of the walking component, and enable precise control of the position of the shot peening component.

[0015] Furthermore, the shot peening assembly includes a mounting frame, a shot peening robot, and a shot peening gun. The shot peening robot is connected to the shot peening gun. The mounting frame moves vertically along the moving frame, and guide wheels that cooperate with the vertical track are provided on both sides of the mounting frame.

[0016] The advantages of adopting the above technical solution are that by setting up a shot peening robot to control the movement of the shot peening gun, the movement position of the shot peening gun is guaranteed to be accurate, the movement trajectory of the shot peening gun is easy to control, the movement is flexible, the product is completely processed, and there are no blind spots.

[0017] Furthermore, the shot peening gun is equipped with a stop device, including a connecting plate, a driving component, a rotating plate, and a stop block. The middle part of the rotating plate is hinged to the connecting plate, and the end is hinged to the output end of the driving component. The stop block is fixed at the end away from the driving component and faces the outlet of the shot peening gun.

[0018] The advantage of adopting the above technical solution is that when it is necessary to avoid positions on the product that do not need to be treated, or when the shot peening gun is spraying shot material that is unstable, the setting of the stop block can effectively block the shot material sprayed by the shot peening gun. The stop block is moved by the rotating plate to achieve the blocking of the shot peening material. During the operation of the shot peening gun, it is not necessary to stop the machine.

[0019] Furthermore, the shot peening assembly also includes a displacement sensor, a sensor baffle, and a baffle driver. The connecting plates are symmetrically arranged to form a mounting cavity with a bottom plate and a top plate. The displacement sensor is disposed in the mounting cavity and connected to the sensor baffle. The mounting cavity has an opening, and the baffle driver drives the sensor baffle to move and block the opening.

[0020] The advantage of adopting the above technical solution is that the displacement sensor is used to sense the distance between the shot peening gun and the product. The distance between the shot peening gun and the product is adjusted before the shot peening gun is used. It does not work during the shot peening process. The entire sensor is installed in the mounting cavity, and the sprayed material will not damage it. When it needs to work, the baffle drive drives the sensor baffle to move, so that there is no obstruction between the moving sensor and the product. After the shot peening gun is in place, the sensor baffle returns to the initial position, which protects the displacement sensor.

[0021] Furthermore, the mounting frame and the shot peening robot are provided with protective shells on their outer sides.

[0022] The advantages of adopting the above technical solution are that the protective shell prevents high-speed shot from being sprayed onto the surface of the robot, avoids the influence of small shot on the joints of the robot, extends the service life of the robot, and ensures the accurate movement of the shot blasting gun.

[0023] Furthermore, the movable frame is located on one side of the horizontal moving device, and the shot peening assembly is disposed on the side of the movable frame.

[0024] The advantages of adopting the above technical solution are that the movable frame and shot peening assembly are set on one side of the movable frame, which saves floor space compared with the frame installation with four legs in the prior art, is suitable for processing large products, and ensures the moving accuracy.

[0025] Furthermore, the horizontal moving device includes two sets of vertically arranged walking components and a track device, and the horizontal driving component simultaneously drives the two sets of walking components to move along the track device.

[0026] The advantage of adopting the above technical solution is that by driving the upper and lower walking components with a set of horizontal moving components, the position of the moving frame is accurate, and at the same time, two sets of walking components are set up at the top and bottom to ensure smooth movement and use with a large stroke.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings.

[0037] like Figure 1-6 As shown, this utility model discloses a truss shot peening device, comprising:

[0038] Mobile frame 1, on which shot peening assembly 6 is installed;

[0039] A horizontal moving device, fixed to a wall or bracket, includes a walking component 2, a track device 3, and a horizontal drive component 4. The walking component 2 is connected to the moving frame 1, and the horizontal drive component 4 drives the walking component 2 to move along the track device 3.

[0040] The vertical moving device 5 includes multiple vertical tracks 51 and a vertical driving device 52. The vertical tracks 51 are arranged on the moving frame 1, and the vertical driving device 52 drives the shot peening assembly 6 to move along the vertical tracks 51.

[0041] The advantages of adopting the above technical solution are that the horizontal and vertical moving devices 5 drive the shot peening assembly 6 to move horizontally and vertically, resulting in a stable structure, small footprint, and applicability to the processing of products of various sizes.

[0042] In some implementations, the walking assembly 2 includes: a mounting plate 21, a walking wheel set, and an auxiliary wheel set. The walking wheel set includes multiple walking wheels 22 that are rotatably mounted on the mounting plate 21. A mounting block is provided on the lower side of the mounting plate 21. The walking wheels 22 are rotatably mounted on the mounting block. The walking wheels 22 move along the track device 3. The walking wheels 22 are symmetrically and inclinedly arranged, straddling the track device 3. A horizontal track 31 is provided at the top of the track device 3. The overall cross-section of the horizontal track 31 is trapezoidal, and its two inclined sides form an inclined surface 32 for the walking wheels 22 to travel on. Each set of walking wheels 22 has four wheels, two on each side, which are in contact with the inclined surface 32 and move along the inclined surface 32. Two sets of walking wheels 22 are installed on the mounting plate 21 to ensure smooth movement.

[0043] In addition, the auxiliary wheel set includes auxiliary wheels 23 symmetrically arranged on both sides of the walking wheel 22. The auxiliary wheels 23 move along both sides of the track device 3. Support plates 24 are provided on both sides of the mounting plate 21. The auxiliary wheels 23 are connected to vertically arranged wheel axles. The auxiliary wheels 23 are rotatably installed. The wheel axles are installed with the support plates 24. The track device 3 also includes a side track 25 located on the side and fixedly installed. The surface of the auxiliary wheels 23 contacts the side track 25. The auxiliary wheels 23 roll along the side track 25. The side track 25 is located on both sides of the horizontal track 31. The auxiliary wheels 23 are clamped on both sides, effectively preventing the mounting frame from moving in the vertical direction and ensuring that the moving frame 1 moves smoothly and stably.

[0044] In some embodiments, the walking assembly 2 also has a cleaning device, including: an air outlet block 7 and jet nozzles 71 installed on both sides of the air outlet block 7. Both the air outlet block 7 and the jet nozzles 71 are connected to an air source and are provided with multiple air outlets facing the track device 3. The air outlet block 7 is fixedly installed at one end of the mounting plate 21, and the surface with the air outlets is parallel to the inclined surfaces 32 on both sides of the horizontal track 31, so that the air outlet direction of the air outlet block 7 is towards the inclined surfaces 32 of the horizontal track 31, so as to avoid impurities on the horizontal track 31 from affecting the operation of the walking wheel 22 and ensuring the movement accuracy. At the same time, the jet nozzles 71 are fixedly installed on both sides of the air outlet block 7, facing the side track, to avoid the accumulation of shot on the side track 25. The air outlet block 7 and the jet nozzles 71 are installed at both ends of the mounting plate 21, which facilitates the reciprocating movement of the walking assembly 2.

[0045] In some implementations, the shot peening assembly 6 includes a mounting frame 61, a shot peening robot 62, and a shot peening gun 63. The shot peening robot 62 can be selected as needed, and can be six-axis or eight-axis. An extension is fixed to the end of the robot, and the shot peening gun is fixedly connected to the extension. The shot peening gun 63 is connected to a pipe and is connected to a shot peening generating device. The shot peening generating device is used to provide shot and accelerate it before it is ejected from the shot peening gun 63. The specific working principles and working structures of the shot peening generating device and the shot peening gun 63 are all prior art and will not be described again here. The shot peening robot 62 is connected to the shot peening gun 63, and the mounting frame 61 moves vertically along the moving frame 1. The vertical drive device 52 drives the vertical frame 61. Guide wheels 64 that cooperate with the vertical track 51 are fixedly installed on both sides of the mounting frame 61. The vertical drive device 52 is a gear and rack assembly. A vertical rack 9 is fixedly installed on the side of the moving frame 1. A gear is set on the mounting frame 61. The gear meshes with the rack 9. The gear is controlled to rotate by a motor. The rotating gear moves up and down along the rack 9, changing the height of the shot peening assembly 6 and realizing the height change of the shot peening assembly 6. At the same time, it can ensure the movement accuracy of the mounting frame 61. The transmission accuracy is high and the structure is compact. When combined with a six-axis or eight-axis robot, the movement trajectory of the shot peening gun 63 is flexible, and the product is completely processed without dead angles.

[0046] Furthermore, the shot peening gun 63 is equipped with a stop device, including a connecting plate 8, a driving member 81, a rotating plate 82, and a stop block 83. The connecting plate 8 is symmetrically arranged and fixed to the end of the protruding member. The middle part of the rotating plate 82 is hinged to the connecting plate 8, and the end is hinged to the output end of the driving member 81. The stop block 83 is fixed at the end away from the driving member 81 and faces the outlet of the shot peening gun 63. The driving member 81 can be a cylinder, the main body of which is hinged to the connecting plate 8, and the protruding end is hinged to the stop block 83. The stop block 83 is driven to rotate around the hinge point between the middle part and the connecting plate 8.

[0047] When it is necessary to avoid areas on the product that do not require treatment, or when the shot blasting gun 63 is spraying shot uneasily, the cylinder extends. At this time, the stop block 83 moves to the outlet of the shot blasting gun 63, blocking the shot blasting path of the shot blasting gun 63, but not stopping the shot blasting gun 63 from blasting. When it moves to the position that needs treatment, or when the shot blasting gun 63 sprays shot uneasily, the cylinder retracts, and the stop block moves with the rotating plate 82 to avoid the shot spraying path. At this time, the shot blasting gun 63 performs surface treatment on the product, avoiding frequent switching of equipment and improving production efficiency.

[0048] Furthermore, the shot peening assembly 6 also includes a displacement sensor 67, a sensor baffle 65, and a baffle drive 66. The connecting plates 8 are symmetrically arranged, forming a mounting cavity with a bottom plate and a top plate. The displacement sensor 67 is disposed within the mounting cavity and fixed to the sensor baffle 65. The baffle drive 66 is a cylinder, with its main body fixedly installed within the mounting cavity and its extended end connected to the baffle drive 66. The mounting cavity has an opening. The baffle drive 66 drives the sensor baffle 65 to move and block the opening. The displacement sensor 67 can be a laser displacement sensor, locked and fixed inside the baffle. When the position of the shot peening gun 63 needs to be adjusted, the baffle drive extends, causing the displacement sensor 67 to extend from the opening to adjust the position of the shot peening gun 63. After adjustment, the baffle drive 66 retracts, and the displacement sensor 67 returns to the mounting cavity. At this time, the sensor baffle 65 precisely blocks the opening, preventing damage to the displacement sensor 67 from the shot and extending its service life.

[0049] In some implementations, a protective shell is provided on the outside of the mounting frame 61 and the shot peening robot 62. The protective shell is locked and fixed to the mounting frame 61 to protect the internal robot from the influence of shot and dust.

[0050] In some implementations, the movable frame 1 is located on one side of the horizontal moving device, and the shot peening assembly 6 is set on the side of the movable frame 1. This arrangement allows the entire device to be installed along the wall, greatly reducing the space occupied.

[0051] Furthermore, the horizontal moving device includes two sets of vertically arranged walking components 2 and a track device 3. The horizontal drive component 4 simultaneously drives the two sets of walking components 2 to move along the track device 3. The horizontal drive component 4 is also a gear and rack structure 9. The track device 3 has a support plate for mounting the track, which has an I-shaped cross-section and multiple vertically arranged support plates on the side to provide support and prevent deformation of the support plate. The rack 9 is fixedly mounted on the support plate with its downward orientation. The gears are rotatably fixed on the mounting frame 61. The two sets of gears are connected by a connecting shaft 91, which is vertically arranged and driven to rotate by a motor. The connecting shaft 91 is connected to the gear shaft through a reducer. One motor can control the joint movement of the two sets of walking components 2. A protective pipe is provided on the outside of the connecting shaft 91 for protection.

[0052] In the working process, the shot peening assembly 6 is first moved to the initial shot peening position by the horizontal and vertical moving devices 5. Then, the displacement sensor 67 extends, and the position of the shot peening gun 63 is further adjusted by the robotic arm. After it is in position, the stop block 83 blocks the outlet of the shot peening gun 63, and the shot peening gun 63 starts. When the shot material is stable, the stop block 83 moves and the product is processed. During the processing, the shot peening gun 63 moves along the set path under the drive of the horizontal moving device, the vertical moving device 5, and the robotic arm until the entire shot peening process is completed. The advantages are that the structure is simple and compact, occupies little space, and is suitable for processing large products. The shot peening assembly 6 has high moving precision, and the moving trajectory of the shot peening gun 63 is flexible and controllable, which can ensure that the product is processed without any dead angles. The walking assembly 2 is designed to be stable and equipped with a cleaning device, which effectively ensures the smoothness of movement and service life.

[0053] 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.
