Description

Technical Field

[0001] This invention relates to the field of chain processing, and in particular to a shot blasting device for chain processing. Background Technology

[0002] Chains, as core components of mechanical transmission and traction, are widely used in lifting and transportation, construction machinery, and agricultural machinery. During their processing, oxide scale, rust, oil stains, and burrs easily remain on the surface, affecting not only the appearance quality but also reducing the adhesion and fatigue strength of subsequent coatings, thus shortening their service life. Shot blasting is a key process for strengthening and cleaning the chain surface. By impacting the chain surface with high-speed shot, rust removal, deburring, and surface strengthening can be achieved in one integrated process.

[0003] Existing shot blasting equipment often suffers from problems such as chain conveyor jamming, uneven shot coverage, high energy consumption, and poor adaptability. Furthermore, the irregular surface of the chain leads to numerous dead zones during shot blasting. Therefore, a shot blasting device for chain processing is proposed. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention proposes a shot blasting equipment for chain processing, which can perform comprehensive shot blasting on chains, improve processing efficiency and effect, and has strong versatility for different chains.

[0005] To solve the above-mentioned technical problems, the basic technical solution proposed by this invention is as follows:

[0006] A shot blasting machine for chain processing includes a housing with a guide rail suspended through it. Shot blasting equipment is rotatably mounted on the front and rear sides of the housing.

A turntable is rotatably mounted onto the lower end of the slide block, and a toothed ring is fitted onto the outer side of the turntable. A rotating shaft is rotatably fitted through both sides of the slide block. A gear and a cross-grooved disc are respectively fitted onto the lower and upper sides of the rotating shaft, and the gear meshes with the toothed ring. A winding reel is rotatably fitted on both radial sides of the lower end face of the turntable.

[0007] A servo motor is mounted on the mounting frame, and the output end of the servo motor extends through the mounting frame to its upper and lower sides. Gear 5 and sprocket are respectively mounted on the upper and lower sides of the servo motor output end on the mounting frame. The sprockets on both sides of the servo motor output end are also symmetrically arranged with the same sprockets and are mounted on the lower end face of the slide. A drive component is provided at the lower end of the sprockets on both sides. The drive component is used to flexibly connect with the cross-shaped slot plate and drive gear 1 to rotate. A linkage component is also provided on the turntable. The linkage component is used to drive the winding reels on both radial sides of the turntable to wind and unwind the hanging ropes connected to them respectively when the turntable rotates. An angle adjustment component is also provided in the machine box. The angle adjustment component is used to adjust the rotation of the shot blasting equipment on both sides to move closer or further apart to adjust the shot blasting direction.

[0008] Preferably, a display and control screen is installed on the front side of the chassis, and openings are provided on both the front and rear sides of the chassis. The guide rail passes through the openings on the front and rear sides of the chassis, and the guide rail is either straight or circular. A shot supply module is also installed inside the chassis, and the shot blasting equipment on both sides is connected to the shot supply module. Each shot blasting equipment is equipped with a fan-shaped guide port.

[0009] Preferably, the drive assembly includes a chain, a square sleeve, a square sleeve, a limiting sleeve, and a cross-shaped locking key. The chain is fitted onto the outer side of each sprocket. The square sleeve is connected to the lower end face of the sprockets on both sides and is coaxially arranged with the sprockets. The square sleeve is slidably fitted onto the outer side of the square sleeve. The limiting sleeve is connected to the lower end of the square sleeve. The cross-shaped locking key is slidably fitted into the limiting sleeve, with its lower end extending below the limiting sleeve and engaging with the cross-shaped locking slot to insert a locking sleeve.

[0010] Preferably, a sleeve plate is rotatably fitted on the outer side of the limiting sleeve, and telescopic components are installed on both sides of the lower end of the mounting bracket, with the lower end of each telescopic component connected to the sleeve plate on its respective side.

[0011] Preferably, the lower end of the limiting sleeve has a limiting port, which horizontally limits the cross-shaped locking key, and one end of the cross-shaped locking key is connected to the inner wall of the limiting sleeve by a spring.

[0012] Preferably, the linkage assembly includes a toothed ring, an opening, a second rotating shaft, a second gear, a third gear, a third rotating shaft, and a fourth gear. The toothed ring is installed on the lower end face of the slide and coaxially arranged on the upper end of the turntable. The opening is radially opened on both sides of the turntable. The second rotating shaft is rotatably fitted onto the inner walls of the opening on both sides of the turntable. The second and third gears are both fitted onto the outer ends of the second rotating shaft, and the second and third gears are symmetrically arranged in the openings on both sides. The third rotating shaft is rotatably arranged on both sides of the turntable. The two winding reels are connected to the two rotating shafts on both sides, which are close to each other. The fourth gear is connected to the two rotating shafts on both sides, which are far apart from each other, and meshes with the third gear on each side.

[0013] Preferably, a sleeve is installed on both sides of the lower end face of the turntable, and the three rotating shafts on both sides are installed in the sleeve and extend on both sides of the sleeve. The openings on both sides are located on the sides of the sleeves that are far apart from each other.

[0014] Preferably, the angle adjustment assembly includes a shaft, a disc, a gear six, a sliding frame, and a rack. The shaft is rotatably mounted inside the housing and is arranged symmetrically. The shot blasting devices on both sides are mounted on the shaft. The upper end of the mounting frame, near the shot blasting device, is rotatably mounted with a gear five that is identical to and meshes with the gear five mounted on the output end of the servo motor. The disc is coaxially mounted on the upper end of the gear five. The gear six is ​​mounted on the shaft and positioned above the shot blasting device. The sliding frame is slidably mounted on the inner wall of the housing. The rack is mounted on both sides of the sliding frame and meshes with the gear six on both sides respectively. A rotating plate is rotatably connected between the upper surface of the disc and the sliding frame.

[0015] Preferably, the rotation connection point of the rotating plate on the disk is not located at the center of the disk, but at the radial outer edge of the disk.

[0016] Preferably, a guide rod is installed on the inner wall of the chassis, and a sleeve is connected to the upper end of the sliding frame. The sleeve is slidably fitted on the outside of the guide rod, and the guide rod and the sleeve are provided in pairs.

[0017] The beneficial effects of this invention are:

[0018] 1. The technical solution of the present invention is to set multiple slides on the guide rail, and each slide can be suspended by two ropes. The guide rail is controlled to transport the slide to the corresponding shot blasting equipment. The telescopic component drives the square sleeve to move down. Then, the telescopic component is controlled to drive the square sleeve to move down and push the limit sleeve and the cross key inside it to move down to the corresponding sleeve of the cross slot plate. Then, the servo motor is driven to drive the sprocket and chain to rotate, which can drive the square sleeve rod and the square sleeve to rotate. The cross key drives the cross slot plates on both sides and the gear to rotate synchronously. Through meshing, the gear ring and the turntable rotate, so that the chain to be processed suspended below the turntable on the slide can follow the turntable to rotate and be collided with the high-speed steel shot thrown by the shot blasting equipment to achieve cleaning. The chain to be processed can also be driven to rotate, improving the comprehensiveness of shot blasting.

[0019] 2. The technical solution of this invention controls the forward and reverse rotation of the servo motor, which drives the turntable to rotate in both directions. When the turntable rotates, the gear two inside the openings on both sides will mesh with the toothed ring, thereby driving the rotating shaft two inside the openings to rotate in opposite directions. This, in turn, drives the gear three. The gear three can also drive the winding discs on both radial sides of the turntable to rotate in opposite directions by meshing with the gear four. This achieves winding on one side and unwinding on the other side, which works together to pull the two suspension ropes. As a result, the two ends of the suspended chain to be processed will repeatedly turn upwards. This allows the chain to be processed to turn up and down repeatedly during shot blasting, achieving comprehensive shot blasting treatment by the shot blasting equipment, avoiding shot blasting dead angles, and improving the shot blasting effect.

[0020] 3. The technical solution of this invention uses the operation of a servo motor to drive the rotation of gear five mounted on its output end, and through meshing, drives the same gear five on the mounting frame to rotate, thereby rotating the disc. This rotation drives the rotating plate connected to the disc along its radial outer edge to rotate, and reciprocates the sliding frame. During the reciprocating sliding process, the sliding frame will drive the racks on both sides to mesh with gears six on the shafts on both sides, causing the shot blasting equipment on both sides to move closer or further apart, adjusting the shot blasting angle within a small range. This allows for more comprehensive shot blasting of the chain to be processed over a larger area, improving processing efficiency and quality. At the same time, it also has a certain degree of versatility for chains of different models and sizes. Attached Figure Description

A gear 13 and a cross-groove plate 14 are respectively mounted on the lower and upper sides of the rotating shaft 12, and the gear 13 meshes with the toothed ring 11. A winding plate 23 is rotatably mounted on both sides of the lower end face of the turntable 10 along the radial direction. A lifting rope 24 is connected and sleeved on both sides of the winding plate 23. The lower ends of the two lifting ropes 24 are respectively connected to the two ends of the chain 25 to be processed for traction.

[0035] A servo motor 26 is mounted on the mounting frame 8, and the output end of the servo motor 26 extends through the mounting frame 8 to its upper and lower sides. Gear 27 and sprocket 28 are respectively mounted on the upper and lower sides of the mounting frame 8 at the output end of the servo motor 26. The same sprocket 28 is also symmetrically arranged on both sides of the sprocket 28 at the output end of the servo motor 26 and is mounted on the lower end face of the slide 9. A drive component is provided at the lower end of the sprocket 28 on both sides. The drive component is used to flexibly connect with the cross slot plate 14 and drive the gear 13 to rotate. A linkage component is also provided on the turntable 10. The linkage component is used to drive the winding plate 23 on both radial sides of the turntable 10 to wind and unwind the hanging rope 24 connected to it respectively when the turntable 10 rotates. An angle adjustment component is also provided in the machine box 1. The angle adjustment component is used to adjust the rotation of the shot blasting equipment 6 on both sides to move closer or further apart to adjust the shot blasting direction.

[0036] The front of the chassis 1 is equipped with a display and control screen 2. The front and rear sides of the chassis 1 are provided with openings. The guide rail 3 runs through the openings on the front and rear sides of the chassis 1. The guide rail 3 is either straight or circular. The chassis 1 is also equipped with a shot supply module 4. The shot blasting equipment 6 on both sides is connected to the shot supply module 4. Each shot blasting equipment 6 is equipped with a fan-shaped guide port 7.

[0037] The display and control screen 2 is an existing control assembly that can intelligently control the comprehensive operation of the various devices, components, modules and structures inside the chassis 1. The guide rail 3 is an existing electric guide rail that can drive the slide 9 to slide precisely on it. Specifically, it can be an existing electromagnetic guide rail.

[0038] Example 2:

[0039] like Figures 1-9 As shown, the present invention discloses a shot blasting equipment for chain processing. Compared with Embodiment 1, this embodiment discloses the structure of the drive component.

[0040] A shot blasting device for chain processing includes a housing 1, a guide rail 3 suspended through the housing 1, a shot blasting device 6 rotatably mounted on the front and rear sides of the housing 1, a mounting frame 8 centrally mounted above the guide rail 3 on the upper inner wall of the housing 1, a slide seat 9 slidably mounted on the lower end of the guide rail 3, a turntable 10 rotatably mounted on the lower end of the slide seat 9, and a toothed ring 11 mounted on the outer side of the turntable 10. A rotating shaft 12 is rotatably mounted through both sides of the slide seat 9. A gear 13 and a cross-grooved disc 14 are respectively mounted on the lower and upper sides of the rotating shaft 12, and the gear 13 meshes with the toothed ring 11. A take-up disc 23 is rotatably mounted on both sides of the lower end face of the turntable 10 along the radial direction. A lifting rope 24 is connected and sleeved on both sides of the take-up disc 23, and the lower ends of the two lifting ropes 24 are respectively connected to the two ends of the chain 25 to be processed for traction.

[0041] A servo motor 26 is mounted on the mounting frame 8, and the output end of the servo motor 26 extends through the mounting frame 8 to its upper and lower sides. Gear 27 and sprocket 28 are respectively mounted on the upper and lower sides of the mounting frame 8 at the output end of the servo motor 26. The same sprocket 28 is also symmetrically arranged on both sides of the sprocket 28 at the output end of the servo motor 26 and is mounted on the lower end face of the slide 9. A drive component is provided at the lower end of the sprocket 28 on both sides. The drive component is used to flexibly connect with the cross slot plate 14 and drive the gear 13 to rotate. A linkage component is also provided on the turntable 10. The linkage component is used to drive the winding plate 23 on both radial sides of the turntable 10 to wind and unwind the hanging rope 24 connected to it respectively when the turntable 10 rotates. An angle adjustment component is also provided in the machine box 1. The angle adjustment component is used to adjust the rotation of the shot blasting equipment 6 on both sides to move closer or further apart to adjust the shot blasting direction.

[0042] The drive assembly includes a chain 29, a square sleeve 30, a square sleeve 31, a limiting sleeve 32, and a cross-shaped locking key 33. The chain 29 is engaged and fitted on the outside of each sprocket 28. The square sleeve 30 is connected to the lower end face of the sprockets 28 on both sides and is coaxially arranged with the sprockets 28. The square sleeve 31 is slidably fitted on the outside of the square sleeve 30. The limiting sleeve 32 is connected to the lower end of the square sleeve 31. The cross-shaped locking key 33 is slidably fitted inside the limiting sleeve 32, and its lower end extends below the limiting sleeve 32 and cooperates with the cross-shaped locking slot 14 to insert the locking sleeve.

[0043] By controlling the servo motor 26 to drive the sprocket 28 mounted on the lower end of the mounting bracket 8 to rotate, the chain 29 can drive the sprockets 28 on both sides, as well as the square sleeve rod 30 and the square sleeve 31 to rotate, thereby driving the limit sleeve 32 and the cross key 33 to rotate. When the cross key 33 and the cross slot plate 14 are fitted with a sleeve, they can drive the rotating shaft 12 and the gear 13 to rotate, thereby driving the gear ring 11 and the turntable 10 to rotate. This allows the chain 25 to be processed, suspended by the rope 24 on the winding trays 23 on both sides of the turntable 10, to rotate with the turntable 10 and rotate within the shot blasting area of ​​the shot blasting equipment 6, achieving a more comprehensive tile blasting process.

[0044] The outer side of the limiting sleeve 32 is fitted with a sleeve plate 35. The lower ends of the mounting bracket 8 are equipped with telescopic components 36 on both sides, and the lower end of each telescopic component 36 is connected to the sleeve plate 35 on its respective side.

[0045] The lower end of the limiting sleeve 32 has a limiting port, which horizontally limits the cross key 33. One end of the cross key 33 is connected to the inner wall of the limiting sleeve 32 by a spring 34, so that the cross key 33 can be limited to prevent rotation along the axial direction of the limiting sleeve 32, and can only slide along the axial direction of the limiting sleeve 32.

[0046] This allows the telescopic component 36 to move the sleeve 35, the limiting sleeve 32, and the square sleeve 31 up and down without affecting the square sleeve 31's rotation following the square sleeve rod 30. When the square sleeve 31 moves down, the limiting sleeve 32 will cause the cross key 33 to move down and be inserted into the cross slot plate 14. When the cross key 33 and the cross slot plate 14 can correspond, they can be directly inserted. When they cannot correspond, the cross key 33 will be compressed into the limiting sleeve 32 until it can correspond to the cross slot plate 14. Under the action of the spring 34, the two will cooperate and be inserted.

[0047] Example 3:

[0048] like Figures 1-9 As shown, the present invention discloses a shot blasting equipment for chain processing. Compared with Embodiment 2, this embodiment discloses the structure of the linkage component.

[0049] A shot blasting device for chain processing includes a housing 1, a guide rail 3 suspended through the housing 1, a shot blasting device 6 rotatably mounted on the front and rear sides of the housing 1, a mounting frame 8 centrally mounted above the guide rail 3 on the upper inner wall of the housing 1, a slide seat 9 slidably mounted on the lower end of the guide rail 3, a turntable 10 rotatably mounted on the lower end of the slide seat 9, and a toothed ring 11 mounted on the outer side of the turntable 10. A rotating shaft 12 is rotatably mounted through both sides of the slide seat 9. A gear 13 and a cross-grooved disc 14 are respectively mounted on the lower and upper sides of the rotating shaft 12, and the gear 13 meshes with the toothed ring 11. A take-up disc 23 is rotatably mounted on both sides of the lower end face of the turntable 10 along the radial direction. A lifting rope 24 is connected and sleeved on both sides of the take-up disc 23, and the lower ends of the two lifting ropes 24 are respectively connected to the two ends of the chain 25 to be processed for traction.

[0050] A servo motor 26 is mounted on the mounting frame 8, and the output end of the servo motor 26 extends through the mounting frame 8 to its upper and lower sides. Gear 27 and sprocket 28 are respectively mounted on the upper and lower sides of the mounting frame 8 at the output end of the servo motor 26. The same sprocket 28 is also symmetrically arranged on both sides of the sprocket 28 at the output end of the servo motor 26 and is mounted on the lower end face of the slide 9. A drive component is provided at the lower end of the sprocket 28 on both sides. The drive component is used to flexibly connect with the cross slot plate 14 and drive the gear 13 to rotate. A linkage component is also provided on the turntable 10. The linkage component is used to drive the winding plate 23 on both radial sides of the turntable 10 to wind and unwind the hanging rope 24 connected to it respectively when the turntable 10 rotates. An angle adjustment component is also provided in the machine box 1. The angle adjustment component is used to adjust the rotation of the shot blasting equipment 6 on both sides to move closer or further apart to adjust the shot blasting direction.

[0051] The linkage assembly includes a toothed ring 15, an opening 16, a second rotating shaft 17, a second gear 18, a third gear 19, a third rotating shaft 21, and a fourth gear 22. The toothed ring 15 is installed on the lower end face of the slide 9 and is coaxially arranged on the upper end of the turntable 10. The opening 16 is opened radially along the turntable 10 on both sides. The second rotating shaft 17 is rotatably fitted on the inner walls of the two sides of the opening 16 along the radial direction of the turntable 10. The second gear 18 and the third gear 19 are both fitted on the two ends of the outer side of the second rotating shaft 17, and the second gear 18 and the third gear 19 are symmetrically arranged in the two openings 16. The third rotating shaft 21 is rotatably arranged on both sides of the radial direction of the turntable 10. The two winding discs 23 are connected to the two ends of the third rotating shaft 21 that are close to each other. The fourth gear 22 is connected to the two ends of the third rotating shaft 21 that are far away from each other and meshes with the third gear 19 on each side.

[0052] This causes the servo motor 26 to rotate in both directions, driving the turntable 10 to rotate in both directions as well. When the turntable 10 rotates, the gear 18 inside the openings 16 on both sides will mesh with the toothed ring 15, causing the shaft 17 inside the openings 16 to rotate in the opposite direction, which in turn drives the gear 19. The gear 19 can also mesh with the gear 22 to drive the winding discs 23 on both sides of the turntable 10 to rotate in the opposite direction, achieving winding on one side and unwinding on the other side, which works together to pull the two suspension ropes 24. As a result, the two ends of the suspended chain 25 to be processed will repeatedly turn upwards, so that during shot blasting, the chain 25 to be processed can turn up and down repeatedly due to repeated adjustments, achieving full shot blasting treatment by the shot blasting equipment 6, avoiding the formation of shot blasting dead angles, and improving the shot blasting effect.

[0053] Sleeves 20 are installed on both sides of the lower end face of turntable 10. The rotating shafts 21 on both sides are fitted into the sleeves 20 and extend on both sides of the sleeves 20. The openings 16 on both sides are located on the sides of the sleeves 20 that are far apart from each other. The sleeves 20 can stably fit the rotating shafts 21 to ensure the stability of the rotation of the rotating shafts 21, so that when the gear 19 is driven to rotate, it can stably drive the winding reel 23 to rotate.

[0054] Example 4:

A rotating shaft 12 is rotatably mounted through both sides of the slide seat 9. A gear 13 and a cross-grooved disc 14 are respectively mounted on the lower and upper sides of the rotating shaft 12, and the gear 13 meshes with the toothed ring 11. A take-up disc 23 is rotatably mounted on both sides of the lower end face of the turntable 10 along the radial direction. A lifting rope 24 is connected and sleeved on both sides of the take-up disc 23, and the lower ends of the two lifting ropes 24 are respectively connected to the two ends of the chain 25 to be processed for traction.

[0057] A servo motor 26 is mounted on the mounting frame 8, and the output end of the servo motor 26 extends through the mounting frame 8 to its upper and lower sides. Gear 27 and sprocket 28 are respectively mounted on the upper and lower sides of the mounting frame 8 at the output end of the servo motor 26. The same sprocket 28 is also symmetrically arranged on both sides of the sprocket 28 at the output end of the servo motor 26 and is mounted on the lower end face of the slide 9. A drive component is provided at the lower end of the sprocket 28 on both sides. The drive component is used to flexibly connect with the cross slot plate 14 and drive the gear 13 to rotate. A linkage component is also provided on the turntable 10. The linkage component is used to drive the winding plate 23 on both radial sides of the turntable 10 to wind and unwind the hanging rope 24 connected to it respectively when the turntable 10 rotates. An angle adjustment component is also provided in the machine box 1. The angle adjustment component is used to adjust the rotation of the shot blasting equipment 6 on both sides to move closer or further apart to adjust the shot blasting direction.

[0058] The angle adjustment assembly includes a shaft 5, a disc 37, a gear 6 38, a sliding frame 41, and a rack 42. The shaft 5 is rotatably mounted inside the housing 1, and two are symmetrically arranged. The shot blasting devices 6 on both sides are mounted on the shaft 5. The upper end of the mounting bracket 8, near the shot blasting device 6, is rotatably mounted with the same gear 5 27 as the gear 5 27 mounted on the output end of the servo motor 26, and meshes with it. The disc 37 is coaxially mounted on the upper end of the gear 5 27. The gear 6 38 is mounted on the shaft 5 and is located above the shot blasting device 6. The sliding frame 41 is slidably mounted on the inner wall of the housing 1. The rack 42 is mounted on both sides of the sliding frame 41 and meshes with the gear 6 38 on both sides respectively. A rotating plate 43 is rotatably connected between the upper end face of the disc 37 and the sliding frame 41.

[0059] The rotation connection point of the rotating plate 43 on the disk 37 is not located at the center of the disk 37, but at the radial outer edge of the disk 37.

[0060] A guide rod 39 is installed on the inner wall of the chassis 1, and a sleeve 40 is connected to the upper end of the slide frame 41. The sleeve 40 is slidably sleeved on the outside of the guide rod 39. There are two corresponding guide rods 39 and sleeves 40.

[0061] The operation of the servo motor 26 drives the gear 27 mounted on its output end to rotate, and through meshing, drives the same gear 27 on the mounting bracket 8 to rotate, thereby rotating the disc 37. This rotates the rotating plate 43 connected to the disc along its radial outer edge, and pulls the slide frame 41 back and forth. During the back and forth sliding process, the slide frame 41 will drive the racks 42 on both sides to mesh with the gears 38 on the shafts 5 on both sides, causing the shot blasting equipment 6 on both sides to move closer or further apart to adjust the shot blasting angle within a small range. This allows for more comprehensive shot blasting of the chain 25 to be processed in a larger area, improving processing efficiency and quality. At the same time, it also has a certain degree of versatility for different models and sizes of chains 25 to be processed.
