Description

Technical Field

[0001] This utility model relates to the field of thermal spraying technology, and in particular to a multi-station movable column thermal spraying device. Background Technology

[0002] Thermal spraying refers to heating and melting coating materials, atomizing them into extremely fine particles using a high-speed airflow, and then spraying them onto the workpiece surface at high speed to form a coating. By selecting different coating materials according to needs, one or more properties such as wear resistance, corrosion resistance, oxidation resistance, and heat resistance can be obtained.

[0003] Most existing thermal spraying structures have only one spray gun, and the position of the spray gun is fixed and the angle is not adjustable. Usually, the spraying surface is changed by adjusting the position of the part to be sprayed, which takes time to adjust the posture and position of the workpiece. Furthermore, a single spray gun cannot meet the needs of simultaneous spraying, and can only spray one workpiece at a time, which reduces production efficiency, has a long production cycle, and cannot meet the requirements of high-efficiency production. Utility Model Content

[0004] The present invention aims to provide a multi-station movable column thermal spraying device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A multi-station movable column thermal spraying device includes a worktable with a drive groove. Several sets of movable columns are rotatably connected to the worktable, each set connected to a worm gear. A worm is rotatably connected to the worktable. A motor is connected to the worktable, with its output end connected to the worm. The worm meshes with the worm gear. Extension columns are connected to the movable columns, and support platforms are connected to the extension columns. An angle adjustment device is connected to the support platform, including a connecting block connected to a spray gun.

[0007] Preferably, the worktable has a first slide groove, and a slider is slidably connected to the inner wall of the first slide groove. The movable column is rotatably connected to the slider. The worktable also has a second slide groove, and the movable column is slidably connected to the second slide groove.

[0008] Preferably, the longitudinal section of the groove and the slider is convex.

[0009] Preferably, the movable column has a hidden groove, the extension column is slidably connected to the hidden groove, the movable column is threaded with a bolt, and the extension column has several sets of slots, which are engaged with the bolts.

[0010] Preferably, the angle adjustment device further includes a mounting frame, a rotating shaft rotatably connected to the mounting frame, a gear connected to the rotating shaft, a connecting block connected to the rotating shaft, a connecting rod slidably connected to the mounting frame, a handle and a locking tooth connected to both ends of the connecting rod respectively, the locking tooth cooperating with the gear, and a spring sleeved on the outside of the connecting rod, with both ends of the spring connected to the mounting frame and the handle respectively.

[0011] The beneficial effects of this technical solution compared to existing technologies are as follows:

[0012] (1) This technical solution, by setting up several sets of movable rods, worm gears, and worms, can simultaneously perform thermal spraying operations on multiple workpieces, greatly improving production efficiency and reducing processing time during batch production. Furthermore, it can drive the spray guns to rotate, eliminating the need to spend time adjusting the workpiece's posture and position. It can also simultaneously drive multiple worm gears connected to the movable rods to rotate synchronously, ensuring that the rotation angle and speed of all spray guns remain consistent, guaranteeing consistency and uniformity during multi-station spraying, and contributing to improving the quality stability and consistency of the coating on each workpiece.

[0013] (2) By setting up slide groove one, slide groove two, and slider, the worm gear can be driven away from the worm, thus releasing the rotation state of some spray guns. This facilitates operation at specific workstations without affecting the normal operation of other workstations, improving the flexibility and adaptability of the equipment. When some spray guns do not need to rotate, separating their worm gear from the worm prevents the worm gear and worm of these spray guns from continuing to mesh and rotate in a non-working state, thereby reducing unnecessary wear, extending the service life of transmission components, reducing equipment maintenance costs, and reducing the overall energy consumption of the device.

[0014] (3) By setting a slide groove and a slider with a convex cross section, the range of motion of the slider in the slide groove can be limited, so that it can only slide along the direction of the slide groove and will not detach in the direction perpendicular to the slide groove, thus ensuring the stability of the connection between the movable column and the worktable, and thus ensuring the reliability of the entire thermal spraying device during operation.

[0015] (4) By setting hidden grooves, extension columns, bolts and slots, the distance between the support platform and the spray gun and the worktable can be changed, that is, the spraying distance between the spray gun and the workpiece can be adjusted, thereby meeting a variety of spraying needs and improving the versatility and adaptability of the device.

[0016] (5) By setting a rotating shaft, gears, and locking teeth, the spray gun angle can be finely adjusted to meet the precise requirements of different workpiece surface shapes and spraying processes for the spray gun angle, which helps to improve the uniformity and accuracy of spraying and ensure coating quality. By setting a spring, the locking teeth are kept in engagement with the gears when not subjected to external force, preventing accidental changes in the spray gun angle. Attached Figure Description

Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0024] like Figure 1-5 The multi-station movable column thermal spraying device shown includes a worktable 1. The worktable 1 has a drive groove 2 and several sets of sliding grooves 14 inside. The top of each sliding groove 14 communicates with the drive groove 2. A slider 15 is slidably connected to the inner wall of each sliding groove 14. The longitudinal sections of both the sliding groove 14 and the slider 15 are convex, and there is a certain amount of friction between the slider 15 and the sliding groove 14. A movable column 3 is rotatably connected to the center of the top wall of the slider 15. A second sliding groove 16 is formed on the top wall of the worktable 1. The movable column 3 passes through the drive groove 2 and the second sliding groove 16 and is slidably connected to the inner wall of the second sliding groove 16. A worm gear 4 is connected to the outer wall of the movable column 3, and the worm gear 4 is located inside the drive groove 2. A worm 5 is rotatably connected to the worktable 1, passing through the drive groove 2 and meshing with several sets of worm gears 4. A motor 13 is connected to the side wall of the worktable 1, and the output end of the motor 13 is connected to the worm 5. After the motor 13 is started, its output end drives the worm 5 to rotate. Because the worm 5 meshes with several sets of worm wheels 4, the rotation of the worm 5 will simultaneously drive the rotation of multiple worm wheels 4. Each worm wheel 4 is connected to the movable column 3, so that the movable column 3, supported by the slider 15, can rotate within the second slide groove 16 of the worktable 1, achieving synchronous rotation of multiple workstations. Pulling the movable column 3, causing it to move along the second slide groove 16, will cause the top slider 15 to move along the first slide groove 14, causing the worm wheels 4 to gradually move away from the worm 5. At this time, the rotation of the worm 5 will not drive the rotation of the movable column 3.

[0025] like Figure 1 , Figure 4-5 As shown, the movable column 3 has a hidden groove 6, and an extension column 7 is slidably connected to the inner wall of the hidden groove 6. Bolts 10 are threadedly connected to the side wall of the movable column 3. Several sets of slots 8 are formed on the side wall of the extension column 7, and these slots 8 engage with the bolts 10. The extension column 7 slides within the hidden groove 6 of the movable column 3. After adjusting to a suitable distance, the bolts 10 are screwed into the threaded holes on the side wall of the movable column 3, thus inserting them into the slots 8 on the side wall of the extension column 7, thereby fixing the extension column 7 to the movable column 3. This changes the distance between the support platform 9, the spray gun 12, and the worktable 1. The top of the extension column 7 is connected to the support platform 9, and the support platform 9 is connected to an angle adjustment device. The angle adjustment device includes a mounting frame 11, a rotating shaft 17 rotatably connected to the mounting frame 11, a gear 18 and a connecting block 19 connected to the rotating shaft 17, and a spray gun 12 connected to the connecting block 19. A connecting rod 23 is slidably connected to the side wall of the mounting frame 11. A handle 22 and a locking tooth 20 are respectively connected to both ends of the connecting rod 23. The locking tooth 20 engages with the gear 18. A spring 21 is sleeved on the outside of the connecting rod 23, with both ends connected to the mounting frame 11 and the handle 22. Pulling the handle 22 outward causes the connecting rod 23 to slide against the side wall of the mounting frame 11, at which point the locking tooth 20 disengages from the gear 18. Rotating the spray gun 12 causes the connecting block 19 and the rotating shaft 17 to rotate, and the gear 18 also rotates accordingly, thus adjusting the angle of the spray gun 12. After adjusting to the appropriate angle, releasing the handle 22 causes the locking tooth 20 to re-engage with the gear 18 under the elastic force of the spring 21, locking the angle of the spray gun 12.

[0026] The specific implementation process is as follows:

[0027] In use, the workpiece to be sprayed is held in place by the clamping device. The movable column 3 connected to the extra spray gun 12 is pushed to the other end of the slide groove 16. According to the spraying process requirements, the appropriate distance between the spray gun 12 and the workpiece is determined. The bolts 10 on the side wall of the movable column 3 are loosened, moving it away from any slot 8. The extension column 7 is slid into the appropriate position in the hidden groove 6, and then the bolts 10 are tightened to insert it into the corresponding slot 8, fixing the extension column 7 onto the movable column 3. According to the surface shape of the workpiece and the spraying requirements, the handle 22 on the angle adjustment device is pulled to disengage the retaining tooth 20 from the gear 18. After rotating the spray gun 12 to the appropriate angle, the handle 22 is released, allowing the retaining tooth 20 to re-engage with the gear 18, locking the angle of the spray gun 12. The motor 13 is turned on, driving the worm gear 5 to rotate, causing multiple movable columns 3 and the spray gun 12 to rotate synchronously for spraying.
