Description
Technical Field
[0001] This application relates to the field of workpiece sandblasting, and in particular to a sandblasting mechanism. Background Technology
[0002] Sandblasting is a surface treatment process for workpieces. It relies on a spray gun to spray abrasive materials (copper ore sand, quartz sand, corundum, iron sand, sea sand) at high speed onto the surface of the workpiece to be treated, thereby changing the morphology of the workpiece surface.
[0003] Existing spray guns can only perform sandblasting on flat surfaces. However, some workpieces may have curved surfaces that require sandblasting, and existing spray guns cannot perform uniform sandblasting on curved surfaces, which greatly reduces the sandblasting quality of the workpieces. Utility Model Content
[0004] In order to overcome the shortcomings of the prior art, this application provides a sandblasting mechanism that can uniformly sandblast curved surfaces.
[0005] The sandblasting mechanism provided in this application adopts the following technical solution:
[0006] A sandblasting mechanism includes a frame, a support component mounted on the frame, a swingable sandblasting component mounted on the frame, and a first drive module for driving the sandblasting component to move. The sandblasting component is located to the side of the support component and its output end is disposed towards the support component.
[0007] By adopting the above technical solution, the sandblasting assembly can uniformly sandblast the arc-shaped surface of the workpiece during its oscillation, effectively improving the sandblasting quality of the workpiece.
[0008] In one specific implementation, the swing axis of the sandblasting assembly is perpendicular to the centerline of the support assembly.
[0009] By adopting the above technical solution, the swing stroke of the sandblasting component can be matched with the arc surface of the workpiece, thereby further improving the sandblasting quality of the workpiece.
[0010] In one specific implementation, the sandblasting assembly includes at least one spray gun module. Each spray gun module includes a swingable gun body, a rotating shaft located on the side of the gun body, and a transmission frame connected to the end of the rotating shaft. The axis of the rotating shaft coincides with the swing axis of the gun body, and the transmission frame is connected to the output end of the first drive module.
[0011] In one specific implementation, the transmission frame extends along the direction from the gun body to the support assembly, and the transmission frame has an adjustment groove extending along its length, with the rotating shaft movably inserted into the adjustment groove.
[0012] By adopting the above technical solution, operators can adjust the distance between the gun body and the supporting component by adjusting the position of the rotating shaft in the adjustment groove, so as to meet the sandblasting requirements of workpieces of different sizes.
[0013] In one specific implementation, the spray gun module further includes a mounting bracket disposed on the frame, and the transmission bracket is rotatably connected to the mounting bracket.
[0014] By adopting the above technical solution, the swing stability of the gun body is effectively improved, and the sandblasting quality of the workpiece is improved.
[0015] In one specific implementation, there are two spray gun modules, and a connecting rod is provided between the two spray gun modules. The two ends of the connecting rod are respectively connected to the two transmission frames.
[0016] By adopting the above technical solution, the two gun bodies can be sandblasted synchronously under the drive of the two transmission frames and connecting rods, which effectively improves the sandblasting consistency of adjacent workpieces, thereby improving the overall sandblasting quality of the workpieces.
[0017] In one specific implementation scheme, the support assembly includes a horizontally arranged turntable, a second drive module for driving the turntable to rotate, a plurality of support seats rotatable about their own axis and disposed on the turntable, and a third drive module for driving the plurality of support seats to rotate, wherein the plurality of support seats are arranged circumferentially around the turntable.
[0018] By adopting the above technical solution, multiple workpieces can revolve under the drive of the turntable and the carrier, and pass through the sandblasting component in sequence during the revolution and complete rapid sandblasting, which effectively improves the sandblasting efficiency of the workpieces; in addition, the sandblasting component can perform all-round and uniform sandblasting on the periphery of the workpieces in coordination with the rotation of the carrier, which further improves the sandblasting quality of the workpieces.
[0019] In one specific implementation scheme, the turntable has multiple processing stations arranged around its circumference, the sandblasting assembly is disposed to the side of one of the processing stations, the multiple support seats can pass through the multiple processing stations in sequence during the rotation stroke of the turntable, and a first sand baffle is disposed between each two adjacent processing stations. The first sand baffle is erected and has a clearance opening at its lower end.
[0020] By adopting the above technical solution, the first baffle plate can block the sand sprayed by the sandblasting component, preventing the sand sprayed by the sandblasting component from affecting the workpieces at other processing stations; at the same time, the clearance port can allow the workpiece to pass through, preventing the first baffle plate from interfering with the movement of the workpiece.
[0021] In one specific implementation scheme, the support base includes a base body and a support rod disposed on the base body. An annular second sand baffle is coaxially disposed at the upper end of the turntable, and multiple support rods are respectively disposed on the peripheral side surface of the second sand baffle.
[0022] By adopting the above technical solution, the second baffle plate can block the sand sprayed by the sandblasting component, preventing the sand from seeping into the seat body and affecting the normal rotation of the bearing seat.
[0023] In one specific implementation, the lower part of the frame is also provided with a bucket, and the sandblasting mechanism further includes a sand supply component located between the bucket and the sandblasting assembly, and an exhaust component located above the sandblasting assembly.

[0034] The present application will be further described in detail below with reference to the accompanying drawings.
[0035] See Figure 1-2 As shown, a sandblasting mechanism includes a frame 1, a support component 2 mounted on the frame 1, a swingable sandblasting component 3 mounted on the frame 1, and a first drive module 4 for driving the movement of the sandblasting component 3. The sandblasting component 3 is located to the side of the support component 2, and its output end faces the support component 2. The first drive module 4 is a servo motor, and the workpiece 100 is disc-shaped with a circular arc surface to be sandblasted on its periphery.
[0036] During sandblasting, the workpiece 100 is placed horizontally on the support component 2. The sandblasting component 3 can uniformly sandblast the arc-shaped surface around the workpiece 100 during its swing, effectively improving the sandblasting quality of the workpiece 100.
[0037] In this embodiment, the support component 2 is erected with its centerline extending vertically, and the swing axis of the sandblasting component 3 extends horizontally and is perpendicular to the centerline of the support component 2. In this way, the swing stroke of the sandblasting component 3 can match the arc surface of the side of the workpiece 100, thereby further improving the sandblasting quality of the workpiece 100.
[0038] In this embodiment, the sandblasting assembly 3 includes two spray gun modules 31 arranged side by side along the horizontal direction. The two spray gun modules 31 are capable of sandblasting two workpieces 100 respectively. The arrangement direction of the two spray gun modules 31 is perpendicular to the direction from the sandblasting assembly 3 to the bearing assembly 2. A connecting rod 32 is also provided between the two spray gun modules 31.
[0039] Each spray gun module 31 includes a mounting bracket 315 horizontally mounted on the frame 1, a swingable gun body 311, a rotating shaft 312 located on the side of the gun body 311, and a transmission frame 313 connected to the end of the rotating shaft 312. The axis of the rotating shaft 312 coincides with the swing axis of the gun body 311. One end of the transmission frame 313 is connected to the rotating shaft 312, and the other end is rotatably connected to the mounting bracket 315 via a swing bearing. The swing bearing on one of the transmission frames 313 is connected to the output end of the first drive module 4. The two ends of the connecting rod 32 are respectively connected to the ends of the two transmission frames 313 near the rotating shaft 312.
[0040] In this way, after the first drive module 4 is activated, the first drive module 4 can drive one of the transmission frames 313 to swing. The transmission frame 313 drives the corresponding gun body 311 to swing, and at the same time, it drives the other transmission frame 313 to swing through the connecting rod 32. The other transmission frame 313 drives the corresponding gun body 311 to swing, thereby realizing the synchronous swing and sandblasting of the two gun bodies 311, effectively improving the sandblasting consistency of adjacent workpieces 100, thereby improving the overall sandblasting quality of workpieces 100.
[0041] In this embodiment, the transmission frame 313 extends along the direction from the gun body 311 to the support assembly 2. An adjustment groove 314 extending along the length of the transmission frame 313 is provided on the transmission frame 313. The rotating shaft 312 is movably inserted into the adjustment groove 314 and locked by a locking pin. When dealing with workpieces 100 of different sizes, the operator can adjust the distance between the gun body 311 and the support assembly 2 by adjusting the position of the rotating shaft 312 in the adjustment groove 314 to meet the sandblasting requirements of different workpieces 100.
[0042] In this embodiment, the support assembly 2 includes a horizontally arranged turntable 21, a second drive module 22 for driving the turntable 21 to rotate, eight support seats 23 rotatable about their own axis and disposed on the turntable 21 for loading workpieces 100, and a third drive module 24 for driving the eight support seats 23 to rotate. The eight support seats 23 are arranged circumferentially around the turntable 21.
[0043] The axis of the support 23 extends vertically. The second drive module 22 is a servo motor located at the bottom of the turntable 21. The third drive module 24 includes a drive wheel that is rotatable around the vertical direction, a motor for driving the drive wheel to rotate, eight driven wheels that are respectively connected to the lower ends of the eight support 23s, and a transmission belt that is connected to the drive wheel and the eight driven wheels. The drive wheel is located on the side of the turntable 21. The servo motor drives the drive wheel to rotate. The drive wheel drives the eight driven wheels to rotate synchronously through the transmission belt. The eight driven wheels drive the eight support 23s to rotate synchronously.
[0044] In this way, the workpiece 100 can revolve under the drive of the turntable 21, and pass through the sandblasting component 3 in sequence during the revolution and complete the rapid sandblasting, which effectively improves the sandblasting efficiency of the workpiece 100; and the sandblasting component 3 can perform all-round and uniform sandblasting on the periphery of the workpiece 100 in cooperation with the rotation of the support seat 23, which further improves the sandblasting quality of the workpiece 100.
[0045] In this embodiment, four processing stations are arranged around the circumference of the turntable 21. These four processing stations include a loading / unloading station, two feeding stations, and a sandblasting station. The sandblasting assembly 3 is located to the side of the sandblasting station. The loading / unloading station is opposite to the sandblasting station, and the two feeding stations are also opposite to each other. The loading / unloading station, one of the feeding stations, the sandblasting station, and the other feeding station are arranged sequentially around the axial direction of the turntable 21. The eight support seats 23 can pass through the four processing stations sequentially during the rotation stroke of the turntable 21 and complete the sandblasting. During sandblasting, the sandblasting station contains two support seats 23, and the two spray gun modules 31 simultaneously sandblast the workpieces 100 on the two support seats 23. During loading / unloading, the loading / unloading station contains two support seats 23, and the operator can simultaneously load and unload the two support seats 23.
[0046] Furthermore, a first baffle plate 5 is provided between each pair of adjacent processing stations. The first baffle plate 5 is erected, with its upper end connected to the frame 1 and its lower end having a clearance opening 51. The first baffle plate 5 can block the sand sprayed by the sandblasting assembly 3, preventing the sand sprayed by the sandblasting assembly 3 from affecting the workpieces 100 at other processing stations; at the same time, the clearance opening 51 allows the workpieces 100 to pass through, preventing the first baffle plate 5 from interfering with the movement of the workpieces 100.
[0047] In this embodiment, the support base 23 includes a base body 231 and a support rod 232 coaxially mounted on the base body 231 for loading the workpiece 100. A bearing is installed inside the base body 231, and a driven wheel is coaxially connected to the lower end of the base body 231. A ring-shaped second baffle plate 6 is coaxially mounted on the upper end of the turntable 21. The second baffle plate 6 covers eight base bodies 231, and eight support rods 232 are respectively inserted through the peripheral surface of the second baffle plate 6. When the workpiece 100 is loaded onto the support rod 232, the second baffle plate 6 can block the sand sprayed by the sandblasting assembly 3, preventing the sand from seeping into the base body 231 and affecting the bearing inside the base body 231, thereby affecting the normal rotation of the support base 23.
[0048] Furthermore, a cylindrical inner baffle 10 is provided in the middle of the turntable 21. The inner baffle 10 is set vertically and its periphery is connected to multiple first sand-blocking plates 5. The inner baffle 10 can block the sand sprayed by the sandblasting assembly 3, preventing the sand from seeping into the second drive module 22 below the turntable 21 and affecting the operation of the servo motor.
[0049] In this embodiment, both the sandblasting assembly 3 and the supporting assembly 2 are located in the middle of the frame 1. A hopper 7 is also provided at the lower part of the frame 1. The sandblasting mechanism further includes a sand supply assembly 8 located between the hopper 7 and the sandblasting assembly 3, and an exhaust assembly 9 located above the sandblasting assembly 3. The hopper 7 is used to store slurry sand, the sand supply assembly 8 has a sand supply pump for supplying sand to the sandblasting assembly 3, and the exhaust assembly 9 has a hydrocyclone separator for discharging water vapor from the frame 1. The sand supply assembly 8 and the exhaust assembly 9 are existing technologies in the art, and their specific structures and principles are not described in detail here.
[0050] The implementation principle of a sandblasting mechanism according to an embodiment of this application is as follows:
[0051] The operator places the workpiece 100 to be sandblasted onto the support seat 23 through the loading and unloading station. The workpiece 100 is driven by the turntable 21 to reach the sandblasting station in sequence. The sandblasting component 3 sandblasts the arc surface of the workpiece 100 during its swing. After the sandblasting is completed, the workpiece 100 is driven by the turntable 21 to reach the loading and unloading station, and the operator removes the sandblasted workpiece 100.
[0052] 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.
