Description

Technical Field

[0001] This application relates to the technical field of surface treatment equipment, and in particular to a hoisting sandblasting machine. Background Technology

[0002] Sandblasting, as a common surface finishing process, has many advantages such as removing oxide scale, cleaning impurities, increasing surface roughness to improve coating adhesion, and achieving surface finishing. It is widely used in machinery, automotive, aerospace and other fields.

[0003] Most sandblasting machines on the market currently use a rotary table structure. While this type of equipment can achieve relatively uniform sandblasting when dealing with flat or simple-shaped workpieces, it often results in uneven sandblasting coverage and reduced processing effectiveness when handling workpieces with complex curved surfaces, due to limitations in its fixing method and sandblasting angle. Especially for workpieces with significant surface variations, rotary table sandblasting machines struggle to achieve omnidirectional and multi-angle blasting, easily creating blind spots or over-blasted areas, affecting the consistency of the workpiece surface and the overall processing quality. Utility Model Content

[0004] To address the issues of uneven sandblasting coverage and reduced treatment effectiveness of rotary sandblasting machines on complex curved workpieces, this application provides a hoisting sandblasting machine.

[0005] The hoisting sandblasting machine provided in this application adopts the following technical solution: A hoisting sandblasting machine includes a chassis, a hoisting assembly, a drive assembly, and a sandblasting mechanism. The hoisting assembly includes a hoisting shaft, a hoisting support cylinder, and a hoisting component. The hoisting shaft is connected to the upper end of the chassis, and the hoisting support cylinder is connected to the lower end of the hoisting shaft. A driven shaft is connected to the top wall of the hoisting support cylinder, and the axis of the driven shaft is parallel to the axis of the hoisting shaft, with the driven shaft located on one side of the hoisting shaft. The lower end of the driven shaft extends into the hoisting support cylinder, and the hoisting component is located inside the hoisting support cylinder, with its upper end connected to the lower end of the driven shaft. The workpiece is mounted on the hoisting component. The drive assembly includes a first drive motor and a second drive motor, which are connected to the upper end of the chassis. The first drive motor drives the hoisting shaft to rotate, and the second drive motor drives the driven shaft to rotate. The sandblasting mechanism is used to sandblast the workpiece.

[0006] By adopting the above technical solution, this solution utilizes the lifting shaft, lifting support cylinder, and double lifting component structure in the lifting assembly, combined with the coordinated control of the first and second drive motors, to achieve alternating operations between sandblasting and loading / unloading stations, significantly improving production efficiency. The lifting component, through a suspension structure combining the main support rod and the connecting rod, allows complex curved workpieces to rotate a full circumference with the lifting component, effectively avoiding blind spots in sandblasting. The third drive motor in the sandblasting mechanism drives the spray gun to reciprocate through the drive disc, adjusting plate, and drive rod, and achieves multi-angle spraying through the pulling component, overcoming the problems of uneven coverage and reduced effectiveness in processing curved workpieces with rotary sandblasting machines, significantly improving the consistency and quality of sandblasting treatment.

[0007] Preferably, the hoisting component includes a main support rod and hanging rods. The main support rod is arranged vertically, and multiple hanging rods are provided. All multiple hanging rods are connected to the main support rod, and the hanging rods are used to install the workpiece.

[0008] By adopting the above technical solution, the lifting component uses a vertical main support rod and multiple radially arranged hanging rods, which increases the suspension capacity of the workpiece and keeps the workpiece stable during rotation. This structure is beneficial for achieving uniform coverage of complex curved workpieces during multi-angle sandblasting.

[0009] Preferably, the lower end of the driven shaft is connected to a hook, the lifting component includes a hook, the hook is connected to the upper end of the main support rod, and the hook is hooked on the hook; a socket is connected to the bottom wall of the lifting support cylinder, and the lower end of the main support rod is inserted into the socket.

[0010] By adopting the above technical solution, the hook and hook connection method combined with the socket to the lower end of the main support rod makes the installation of the lifting parts simple and accurate, and maintains good transmission stability during high-speed rotation.

[0011] Preferably, a drive sprocket is connected to the output shaft of the first drive motor, and a driven sprocket is connected to the upper end of the hoisting shaft; the drive sprocket is connected to the driven sprocket via a chain.

[0012] By adopting the above technical solution, the first drive motor forms a chain transmission mechanism through the drive sprocket, chain and driven sprocket. The transmission ratio is accurate and the load-bearing capacity is strong. It can reliably realize the 180° forward and reverse conversion of the hoisting shaft and ensure the repeatability of the positioning accuracy of the hoisting support cylinder position switching.

[0013] Preferably, a drive friction wheel is connected to the output shaft of the second drive motor, and a driven friction wheel is connected to the driven shaft, with the drive friction wheel and the driven friction wheel in press-fit contact.

[0014] By adopting the above technical solution, the second drive motor transmits power through the pressing contact between the driving friction wheel and the driven friction wheel, realizing the continuous and uniform rotation of the driven shaft. This friction transmission method operates smoothly and with low noise, allowing the workpiece to rotate at a uniform speed during sandblasting, effectively avoiding excessive or incomplete sandblasting in certain areas.

[0015] Preferably, the sandblasting mechanism includes a deflection assembly and a spray gun. The deflection assembly includes a third drive motor, a drive rod, a pulling frame, and a drive shaft. The third drive motor is connected to the housing, and a drive disc is coaxially connected to the output shaft of the third drive motor. One end of the drive rod is connected to the drive disc, and the axis of the drive rod is perpendicular to the axis of the output shaft of the third drive motor. The connection between the drive rod and the drive disc is located on one side of the axis of the output shaft of the third drive motor. The drive shaft is connected to the housing, and a pulling frame is connected to the drive shaft. The other end of the drive rod is connected to the pulling frame. The spray gun is mounted on the drive shaft, and the nozzle of the spray gun faces the workpiece. The third drive motor drives the drive shaft to reciprocate through the drive disc, drive rod, and pulling frame. The drive shaft drives the spray gun to reciprocate.

[0016] By adopting the above technical solution, the third drive motor in the sandblasting mechanism drives the drive shaft to reciprocate through the drive disc, drive rod, and pull frame, thereby driving the spray gun to swing. This structure expands the coverage of the sandblasting flow, making it suitable for more comprehensive treatment of curved workpieces and improving the uniformity and consistency of sandblasting.

[0017] Preferably, the deflection assembly further includes an adjusting plate, the sidewall of which is parallel to the end face of the drive disk; the drive disk has a connecting groove, one end of the adjusting plate is rotatably connected to the drive disk, and the other end of the adjusting plate has a connecting hole aligned with the connecting groove; the other end of the adjusting plate is positioned on the drive disk by a positioning bolt passing through the connecting groove; a rotating support rod is connected to the adjusting plate, the axis of which is parallel to the axis of the output shaft of the third drive motor; the drive rod is rotatably connected to the adjusting plate via the rotating support rod, and the axis of the drive rod is perpendicular to the axis of the rotating support rod; the positioning bolt is used to adjust the distance between the rotating support rod on the adjusting plate and the output shaft of the third drive motor.

[0018] By adopting the above technical solution, the adjusting plate can be positioned on the drive plate through the connecting groove and positioning bolts, which can change the distance between the rotating support rod and the output shaft, thereby flexibly adjusting the swing amplitude of the spray gun. This design enables the sandblasting mechanism to adapt to workpieces of different sizes and shapes, improving the equipment's process adaptability.

[0019] Preferably, the sandblasting mechanism further includes a pulling assembly, which includes a fixing block, a first support rod, a connecting block, and a second support rod. The fixing block is connected to the drive shaft, one end of the first support rod is connected to the fixing block, and the axis of the first support rod is perpendicular to the axis of the drive shaft. The connecting block is connected to the other end of the first support rod, one end of the second support rod is connected to the connecting block, and the axis of the second support rod is perpendicular to the axis of the drive shaft. An angle is provided between the first support rod and the second support rod. The spray gun is connected to the other end of the second support rod.

[0020] By adopting the above technical solution, the pulling component achieves compound oscillation of the spray gun within a spatial range through a multi-stage connection of a fixed block, a first support rod, a connecting block, and a second support rod. This structure enhances the flexibility of the spray gun's movement, enabling the sandblasting stream to impact the workpiece surface from multiple angles, further improving the sandblasting quality of complex-structured workpieces.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. This solution, through the lifting shaft, lifting support cylinder, and double lifting component structure in the lifting assembly, combined with the coordinated control of the first and second drive motors, achieves alternating operations between sandblasting and loading / unloading stations, significantly improving production efficiency. The lifting component, through a suspension structure combining the main support rod and the connecting rod, allows complex curved workpieces to rotate a full circumference with the lifting component, effectively avoiding blind spots in sandblasting. The third drive motor in the sandblasting mechanism drives the spray gun to reciprocate through the drive disc, adjusting plate, and drive rod, and achieves multi-angle spraying through the pulling component, overcoming the problems of uneven coverage and reduced effectiveness in the treatment of curved workpieces by rotary sandblasting machines, significantly improving the consistency and quality of sandblasting.

A driven sprocket 211 is fixedly connected to the upper end of the hoisting shaft 21. The drive sprocket 311 is connected to the driven sprocket 211 through a chain 33. The first drive motor 31 drives the hoisting shaft 21 to rotate 180° through the drive sprocket 311, the chain 33 and the driven sprocket 211, thereby driving the hoisting support cylinder 22 to rotate 180°.

In this embodiment, two driven shafts 34 and two lifting components 23 are provided, and the two lifting components 23 are respectively mounted on the two driven shafts 34. The two driven shafts 34 are symmetrically arranged on the lifting support cylinder 22 along the axis of the lifting shaft 21.

A driven friction wheel 341 is fixedly connected to the upper end of the driven shaft 34. A driving friction wheel 321 is in close contact with the driven friction wheel 341. The second drive motor 32 drives the driven shaft 34 to rotate a full circumference through the driving friction wheel 321 and the driven friction wheel 341. The lower end of the driven shaft 34 extends from the top wall of the hoisting support cylinder 22 into the hoisting support cylinder 22, and a hook 342 is fixedly connected to the lower end. The first drive motor 31 is used to drive the hoisting support cylinder 22 to rotate 180°, thereby exchanging the positions of the two hoisting components 23, so that the second drive motor 32 can alternately drive the two driven shafts 34 to rotate through the driving friction wheel 321.

[0036] Reference Figures 4-6Two sockets 2231 are fixedly connected to the base plate 223 of the hoisting support cylinder 22, and the two sockets 2231 are located directly below the two hooks 342.

The upper end of the support plate 221 is fixedly connected to the inner top wall of the hoisting support cylinder 22, and the lower end of the support plate 221 is fixedly connected to the bottom plate 223 of the hoisting support cylinder 22. A V-shaped plate 222 is fixedly connected to each of the two sides of the support plate 221, thereby dividing the space between the inner top wall of the hoisting support cylinder 22 and the bottom plate 223 into four sector-shaped spaces. Two hoisting components 23 are located in two symmetrically arranged sector-shaped spaces.

[0039] Reference Figure 1 , Figure 2 and Figure 7 The machine housing 1 has a loading door, with one of the fan-shaped spaces housing the lifting device 23 facing the loading door. A sandblasting mechanism 4 is installed inside the machine housing 1, located on one side of another fan-shaped space housing the lifting device 23. The sandblasting mechanism 4 is used to sandblast the workpiece 6. The purpose of this design is that while one lifting device 23 is sandblasting the workpiece 6, the operator can install the workpiece 6 on the other lifting device 23.

[0040] Reference Figure 2 and Figure 4 After the sandblasting mechanism 4 completes the sandblasting treatment of the workpiece 6 on one hoisting component 23, the first drive motor 31 drives the hoisting support cylinder 22 to rotate 180° to sandblast the workpiece 6 on the other hoisting component 23. During the sandblasting treatment of the workpiece 6, the second drive motor 32 drives the driven shaft 34 to rotate, and the driven shaft 34 drives the hoisting component 23 to rotate, thereby causing the workpiece 6 on the hoisting component 23 to rotate a full circle.

[0041] Reference Figures 8-10 The sandblasting mechanism 4 includes a deflection assembly 41 and a spray gun 43. The deflection assembly 41 includes a third drive motor 411, an adjusting plate 413, a drive rod 414, a pulling frame 415, and a drive shaft 416. (See also...) Figures 1-2 The third drive motor 411 is fixedly connected to the top wall of the housing 1. The output shaft of the third drive motor 411 is horizontally arranged and perpendicular to the length direction of the housing 1. A drive disk 412 is coaxially fixedly connected to the output shaft of the third drive motor 411. A transmission box 112 is provided on one side of the housing 1. The drive disk 412 is located above the transmission box 112. A connecting groove 4121 is provided on the end face of the drive disk 412. In this embodiment, the connecting groove 4121 is an arc-shaped groove. Adjusting plate 413 is mounted on drive disk 412. Specifically, adjusting plate 413 is vertically arranged, with its lower end rotatably connected to drive disk 412. The upper end of adjusting plate 413 has a connecting hole 4131, which is aligned with connecting groove 4121. Adjusting plate 413 is positioned and connected to drive disk 412 by positioning bolt 419. Specifically, the end of the screw in positioning bolt 419 passes through the connecting hole 4131 and exits through connecting groove 4121. The nut in positioning bolt 419 is threaded onto the screw, and the nut also presses and fixes adjusting plate 413 to drive disk 412.

[0042] Reference Figures 8-10 A rotating support rod 4132 is fixedly connected to the adjusting plate 413. The rotating support rod 4132 is located in the middle of the adjusting plate 413, and its axis is parallel to the axis of the output shaft of the third drive motor 411, with the rotating support rod 4132 located on one side of the output shaft of the third drive motor 411. The upper end of the drive rod 414 is rotatably connected to the rotating support rod 4132, and the axis of the drive rod 414 is perpendicular to the axis of the rotating support rod 4132. (Refer to...) Figure 2Three drive shafts 416 are rotatably connected to the chassis 1. The axes of the three drive shafts 416 are horizontally arranged and perpendicular to the length direction of the chassis 1. The three drive shafts 416 are arranged vertically, and their ends extend into the transmission box 112. The end of the upper drive shaft 416 is fixedly connected to a pulling frame 415. In this embodiment, the pulling frame 415 is a V-shaped plate 222 that flips 90° to one side. The bend of the V-shaped plate 222 is fixedly connected to the end of the upper drive shaft 416, and the lower end of the drive rod 414 is rotatably connected to the upper end of the V-shaped plate 222. When the third drive motor 411 is working, the third drive motor 411 drives the V-shaped plate 222 to reciprocate through the drive disc 412, the adjusting plate 413, the rotating support rod 4132, and the drive rod 414. The V-shaped plate 222 then drives the drive shaft 416 to reciprocate. The positioning bolt 419 is used to adjust the distance between the rotating support rod 4132 on the adjusting plate 413 and the output shaft of the third drive motor 411, thereby changing the deflection angle of the V-shaped plate 222 and the drive shaft 416.

[0043] Reference Figures 8-10 The pulling frame 415 drives the intermediate drive shaft 416 to rotate at the same speed and in the same direction via a set of pulling rods 417 and a pulling plate 418. The intermediate drive shaft 416 then drives the lower drive shaft 416 to rotate at the same speed and in the same direction via another set of pulling rods 417 and a pulling plate 418. Specifically, the pulling rods 417 and the pulling plate 418 between the pulling frame 415 and the intermediate drive shaft 416 are used as an example. One end of the pulling plate 418 is fixedly connected to the end of the intermediate drive shaft 416. The length direction of the pulling plate 418 is perpendicular to the axis of the drive shaft 416. The pulling rods 417 are vertically arranged. The lower end of the pulling rods 417 is rotatably connected to the other end of the pulling plate 418, and the upper end of the pulling rods 417 is rotatably connected to the lower end of the V-shaped plate 222.

[0044] Reference Figures 8-10In this embodiment, three sets of pulling components 42 are arranged along the length of each drive shaft 416, and the number of spray guns 43 is the same as the number of pulling components 42. Taking one set of pulling components 42 as an example, the pulling component 42 includes a fixing block 421, a first support rod 422, a connecting block 423, and a second support rod 424. The fixing block 421 is fixedly connected to the drive shaft 416. One end of the first support rod 422 is fixedly connected to the fixing block 421, and the axis of the first support rod 422 is perpendicular to the axis of the drive shaft 416. The connecting block 423 is fixedly connected to the other end of the first support rod 422. One end of the second support rod 424 is connected to the connecting block 423, and the axis of the second support rod 424 is perpendicular to the axis of the drive shaft 416. A fixed angle is provided between the first support rod 422 and the second support rod 424. The spray gun 43 is connected to the other end of the second support rod 424 by a fixing bolt 44, and the nozzle of the spray gun 43 faces the workpiece 6. When the drive shaft 416 rotates, it drives the spray gun 43 to reciprocate through the fixed block 421, the first support rod 422, the connecting block 423 and the second support rod 424.

[0045] Reference Figure 1 A controller 5 is fixedly connected to the side wall of the chassis 1. The first drive motor 31, the second drive motor 32 and the third drive motor 411 are all connected to the controller 5 through leads.

[0046] The implementation principle of a hoisting sandblasting machine according to an embodiment of this application is as follows: The controller coordinates the actions of the first drive motor 31, the second drive motor 32, and the third drive motor 411 to achieve continuous and efficient sandblasting of the workpiece 6. Specifically, the first drive motor 31 drives the hoisting shaft 21 to rotate 180° via the drive sprocket 311, chain 33, and driven sprocket 211, thereby exchanging the positions of the hoisting support cylinder 22 and its two internal hoisting components 23. The hoisting component 23 located on one side of the loading gate facilitates the loading and unloading of the workpiece 6 by workers, while the hoisting component 23 on the other side is in the sandblasting station to be processed by the sandblasting mechanism 4. During the sandblasting process, the second drive motor 32 drives the driven shaft 34 to rotate continuously via the drive friction wheel 321 and driven friction wheel 341, thereby causing the hoisting component 23 to rotate as a whole via the hook 342. The main support rod 231, first connecting rod 232, second connecting rod 233, and hanging rod 234 in the lifting component 23 together form a suspension structure, enabling complex curved workpieces to rotate a full circle with the lifting component 23, effectively avoiding blind spots in sandblasting. Simultaneously, the third drive motor 411 in the sandblasting mechanism 4 drives the drive rod 414 to reciprocate via the drive disc 412, adjusting plate 413, and rotating support rod 4132, which in turn causes the three drive shafts 416 to reciprocate synchronously via the pulling frame 415, pulling rod 417, and pulling plate 418. Multiple sets of pulling components 42 fixed to the drive shafts 416 drive the spray gun 43 to swing. The swing amplitude can be adjusted via the connecting groove 4121 and positioning bolt 419 on the adjusting plate 413, thereby adapting to the sandblasting requirements of workpieces 6 with different shapes.

[0047] This device utilizes the lifting component 23 to rotate the workpiece 6, combined with the swinging motion of the spray gun 43, to achieve multi-angle and more comprehensive sandblasting coverage of complex curved workpieces. This overcomes the problems of uneven coverage and reduced processing effect caused by the fixed method and sandblasting angle limitations of rotary equipment. Simultaneously, the dual-station design enables parallel operation of sandblasting and loading / unloading processes, improving production efficiency.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
