Description

Technical Field

[0001] This utility model relates to supporting equipment for CNC machining centers, and more particularly to a cleaning and drying device for machined workpieces. Background Technology

[0002] Machined workpieces produced by CNC machining centers often contain impurities such as blind holes, threaded holes, flow channels, and steps. These impurities can easily remain in the machining process, affecting subsequent assembly. For example, when impurities are present in threaded holes, the robotic arm may encounter increased resistance during screw tightening due to these impurities. If the resistance reaches the robotic arm's set value, the program will automatically assume the screw is tightened, mistaking a loose screw for a tightened one and proceeding to the next instruction. Therefore, to prevent impurities from affecting subsequent assembly, machined workpieces must be cleaned and dried after machining. Currently, ultrasonic cleaning is used, followed by manual drying by workers at a drying station. This method is cumbersome, labor-intensive, inefficient, costly, and lacks automation. Utility Model Content

[0031] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and preferred embodiments.

[0032] Exemplary embodiments will be described more fully below with reference to the accompanying drawings; however, these exemplary embodiments may be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will enable those skilled in the art to fully understand the scope of this disclosure.

[0033] Where there is no conflict, the various embodiments of this disclosure and the features thereof in the embodiments may be combined with each other. Example 1

[0034] like Figure 1 As shown, the machining workpiece cleaning and drying equipment described in this embodiment includes: a frame 1, a cleaning chamber 2 provided on the frame 1; a workpiece inlet 21 communicating with the cleaning chamber of the cleaning chamber 2 is provided on the top of the cleaning chamber 2; and a top-opening switch door device 3 is provided at the workpiece inlet 21 to open or close the workpiece inlet 21.

[0035] like Figure 4 and Figure 5 As shown, the structure of the top-opening door opening and closing device 3 in this embodiment includes: at least one swing arm 31, each swing arm 31 being hinged to the frame 1; the hinge point a on each swing arm 31 is divided as shown in the figure: the part on one side of the hinge point a is the driving part 32, and the part on the other side of the hinge point a is the connecting part 33; the connecting part 33 on each swing arm 31 is fixed to the top-opening door 35, and the driving part 32 on each swing arm 31 is driven by the door opening and closing driving device, so that each swing arm 31 swings synchronously and in the same direction around its corresponding hinge point a, thereby opening or closing the top-opening door 35.

[0036] When the number of swing arms 31 is set to one, the structure of the door opening and closing drive device 3 is as follows: the cylinder body of the swing cylinder 34 is hinged to the frame 1, and the end of the piston rod of the swing cylinder 34 is hinged to the end of the drive part 32 on the swing arm 31. When the piston rod of the swing cylinder 34 extends downward, it will push... Figure 4 The swing arm 31, in the direction shown, swings counterclockwise around the hinge point a, thereby opening the top-opening door 35, that is, opening the workpiece inlet 21. The state of the top-opening door 35 when it is open is as follows: Figure 5 As shown. Conversely, when the piston rod of the swing cylinder 34 retracts upward, it will push... Figure 5 The swing arm 31, in the direction shown, swings clockwise around the hinge point a, thereby closing the top-opening door 35, that is, closing the workpiece inlet 21. The state of the top-opening door 35 when closed is as follows: Figure 4 As shown.

[0037] When there are two or more swing arms 31, the structure of the door opening and closing drive device 3 can have two configuration forms.

[0038] The first configuration of the door opening and closing drive device is as follows: at least one swing cylinder 34 is provided, the cylinder body of each swing cylinder 34 is respectively hinged to the frame 1, and the piston rod end of each swing cylinder 34 is hinged to the end of the drive part 32 on each swing arm 31 through the same hinge shaft.

[0039] The second configuration of the door opening and closing drive device is as follows: each swing arm 31 corresponds to a swing cylinder 34, the cylinder body of each swing cylinder 34 is respectively hinged to the frame 1, and the piston rod end of each swing cylinder 34 is hinged to the end of the drive part 32 on the corresponding swing arm 31.

[0040] The principle of the door opening and closing drive device in these two configurations is the same as the working principle of the door opening and closing drive device when there is one swing arm 31, so it will not be repeated here.

[0041] like Figure 1 As shown, in this embodiment, the rotating fixture 4 is installed in the cleaning chamber of the cleaning chamber 2 through a rotating support structure, and the rotating fixture 4 is driven to rotate by a rotating drive device; the rotating fixture 4 has a fixture 41 for placing the machined workpiece 100.

[0042] The structure of fixture 41 is designed according to the shape of the machined workpiece, and the fixture 41 varies depending on the structure of the machined workpiece. This solution can use commercially available and suitable fixtures. The key is that after the robotic arm picks up the machined workpiece and places it into the suitable fixture, it will not fall off the fixture 41 or experience significant displacement during subsequent spray cleaning and air drying processes. This ensures that the robotic arm can smoothly place the machined workpiece into the fixture 41 and smoothly remove the cleaned and dried machined workpiece from the fixture 41. This utility model does not protect the specific structure of fixture 41, therefore, the specific structure of fixture 41 will not be described in detail here.

[0043] A nozzle assembly is installed in the cleaning chamber. Each fluid medium inlet of the nozzle assembly is connected to a branch pipe, and each branch pipe is connected to the spray water supply system and the compressed air supply system respectively through a corresponding water-air switching valve. The water-air switching valve is a two-inlet, one-outlet valve, a conventional valve that can be purchased directly from the market. The first inlet of the water-air switching valve is connected to the outlet of the spray water supply system, and the second inlet is connected to the outlet of the compressed air supply system. The water-air switching valve allows the nozzle assembly to switch between spray cleaning and air drying. That is, when the spray water supply system is connected to each nozzle assembly through the corresponding water-air switching valve, each nozzle assembly sprays spray water; when the compressed air supply system is connected to each nozzle assembly through the corresponding water-air switching valve, each nozzle assembly sprays compressed air.

[0044] The machining workpiece cleaning and drying equipment is typically placed next to a CNC machining center, supplemented by a robotic arm. The robotic arm removes the machined workpiece 100 after machining by the CNC machining center. A top-opening door device 3 opens the workpiece inlet 21, and the robotic arm places the removed workpiece 100 onto the fixture 41 in the machined workpiece cleaning and drying equipment before leaving. The top-opening door device 3 then closes the workpiece inlet 21. Next, the water supply system is connected to each nozzle group via water-air switching valves to spray and clean the machined workpiece 100 on the fixture 41. After spray cleaning, the system is switched to compressed air supply system via water-air switching valves to connect to each nozzle group, allowing the machined workpiece 100 on the fixture 41 to be dried by air. After drying, the top-opening door device 3 opens the workpiece inlet 21, and the robotic arm removes the machined workpiece 100 from the fixture 41.

[0045] Furthermore, for a neat and aesthetically pleasing appearance, this design includes a casing surrounding the frame 1, enclosing all components within the casing. An opening is provided in the casing surrounding the top-opening door device 3, and a side-opening door 11 is hinged to this opening. The side-opening door 11 can be hinged to the opening, and a handle can be provided on it for easy gripping by the operator. To facilitate a more direct observation by the operator of whether the top-opening door device 3 is functioning properly and the insertion and removal of machined workpieces 100, a transparent viewing window can also be provided on the side-opening door 11. Of course, maintenance of the top-opening door device 3 can also be performed through this opening.

[0046] The aforementioned machined workpiece cleaning and drying equipment combines spray cleaning and air drying functions. The drive components of the door opening and closing drive device, the start-up components of the spray water supply system and the compressed air supply system, and each water-air switching valve are all designed to be automatically controlled by a program. With the assistance of an automated robotic arm, it can realize automatic loading, automatic spray cleaning, automatic air drying, and automatic material unloading. The entire process takes only about 90 seconds. It has the advantages of comprehensive functions, high degree of automation, high work efficiency, and good cleaning and drying effect. Example 2

[0047] like Figure 1 As shown, the machining workpiece cleaning and drying equipment described in this embodiment includes: a frame 1, a cleaning chamber 2 provided on the frame 1; a workpiece inlet 21 communicating with the cleaning chamber of the cleaning chamber 2 is provided on the top of the cleaning chamber 2; and a top-opening switch door device 3 is provided at the workpiece inlet 21 to open or close the workpiece inlet 21.

[0048] The rotating fixture 4 is installed in the cleaning chamber of the cleaning chamber 2 via a rotating support structure, and the rotating fixture 4 is driven to rotate by a rotating drive device; the rotating fixture 4 has a fixture 41 for placing the machined workpiece 100.

[0049] A nozzle assembly is installed in the cleaning chamber. Each nozzle assembly has a branch pipe connected to its fluid medium inlet. Each branch pipe is connected to a spray water supply system and a compressed air supply system via a corresponding water-air switching valve. The water-air switching valve is a two-inlet, one-outlet valve, a standard valve readily available commercially. The first inlet of the water-air switching valve connects to the outlet of the spray water supply system, and the second inlet connects to the outlet of the compressed air supply system. The water-air switching valve allows the nozzle assembly to switch between spray cleaning and air drying modes. Specifically, when the spray water supply system is connected to the nozzle assembly via the corresponding water-air switching valve, the nozzle assembly sprays spray water; when the compressed air supply system is connected to the nozzle assembly via the corresponding water-air switching valve, the nozzle assembly sprays compressed air.

[0050] like Figure 1 and Figure 11 As shown, the spray water supply system in this embodiment includes: a sewage tank 51, a water storage tank 52, a first circulation pump 53, a second circulation pump 54, a first filter 55, and a second filter 56, all fixedly installed on the frame 1.

[0051] The height of the cleaning chamber 2 is higher than that of the sewage tank 51, and the bottom sewage outlet 22 of the cleaning chamber 2 is connected to the top water inlet 511 of the sewage tank 51. The bottom sewage outlet 22 and the top water inlet 511 can be connected by a central connecting pipe 506.

[0052] The connection between the first circulating pump 53 and the sewage tank 51 can be as follows: the inlet of the first circulating pump 53 is connected to the sewage outlet of the sewage tank 51 through the first connecting pipe 501.

[0053] The connection between the first circulating pump 53 and the sewage tank 51 can also be as follows: the inlet of the first circulating pump 53 is connected to a first pumping pipe, and the inlet of the first pumping pipe is immersed in the sewage in the sewage tank 51.

[0054] The connection between the first circulating pump 53 and the sewage tank 51 can be one of the two methods mentioned above, and the choice can be made according to the actual installation layout and space requirements. Figure 11 shows the first configuration.

[0055] A drain outlet can also be provided at the bottom of the sewage tank 51. The drain outlet is normally closed. When the sewage tank 51 is cleaned and the sewage needs to be discharged, the drain outlet is opened and the sewage is discharged out of the sewage tank 51 through the drain outlet.

[0056] The outlet of the first circulating pump 53 is connected to the inlet of the first filter 55 through the second connecting pipe 502, and the outlet of the first filter 55 is connected to the inlet of the second water storage tank 52 through the third connecting pipe 503.

[0057] The connection between the second circulation pump 54 and the water storage tank 52 can be as follows: the inlet of the second circulation pump 54 is connected to the outlet of the water storage tank 52 through a fourth connecting pipe.

[0058] The connection between the second circulation pump 54 and the water storage tank 52 can also be as follows: the inlet of the second circulation pump 54 is connected to a second water pumping pipe 504, and the inlet of the second water pumping pipe 504 is immersed in the water in the water storage tank 52.

[0059] The connection between the second circulation pump 54 and the water storage tank 52 can be one of the two methods mentioned above, and the choice can be made according to the actual installation layout and space requirements. Figure 11 shows the latter configuration.

[0060] Similarly, a drain outlet is provided at the bottom of the water storage tank 52. The drain outlet is normally closed. When the water storage tank 52 is cleaned and the wastewater needs to be discharged, the drain outlet is opened and the wastewater is discharged out of the water storage tank 52 through the drain outlet.

[0061] The outlet of the second circulating pump 54 is connected to the inlet of the second filter 56 through the fifth connecting pipe 505. The outlet of the second filter 56 is connected to the corresponding fluid medium inlet of the nozzle group through each branch pipe. A water-air switching valve is provided in each branch pipe.

[0062] When the water-air switching valves are switched to connect the spray water supply system with each nozzle group, the water sprayed from each nozzle group sprays and cleans the machined workpiece 100 before falling into the cleaning chamber 2. Then, it passes through the sewage tank 51, the first circulation pump 53, the first filter 55, the water storage tank 52, the second circulation pump 54, and the second filter 56 before returning to the nozzle group, forming a spray cleaning water circulation loop.

[0063] A better option is: such as Figure 1 and Figure 11 As shown, in this embodiment, the height of the water storage tank 52 is higher than the height of the sewage tank 51. An overflow pipe 57 communicating with the inner cavity of the sewage tank 51 is fixedly installed on the top of the sewage tank 51. The top of the overflow pipe 57 passes through the overflow pipe installation hole at the bottom of the water storage tank 52 and extends into the water storage tank 52. The top opening of the overflow pipe 57 is located at the overflow water level of the water storage tank 52.

[0064] When the water level in the storage tank 52 reaches the overflow level, the water in the storage tank 52 will enter the overflow pipe 57 from the top opening of the overflow pipe 57 and eventually return to the sewage tank 51. At this time, the water circulation loop is as follows: the water in the sewage tank 51 enters the storage tank 52 through the first circulation pump 53 and the first filter 55, and the water in the storage tank 52 that exceeds the overflow level returns to the sewage tank 51 through the overflow pipe 57, forming an internal water circulation loop to ensure that the water level in the storage tank 52 never exceeds the overflow level.

[0065] Furthermore, when the spray water from the nozzle assembly needs to have a certain temperature (high ambient temperature), a heater 58 can be installed in the wastewater tank 51 or the water storage tank 52. The heater 58 for heating water is a conventional component, so its structure and working principle will not be described in detail here. The power supply circuit on the heater 58 can be equipped with a control switch to control whether the heater 58 is started or not.

[0066] The aforementioned machined workpiece cleaning and drying equipment combines spray cleaning and air drying functions. The drive components of the door opening and closing drive device 3, the start-up components of the spray water supply system and the compressed air supply system (the start-up components in the spray water supply system are the control switches of the first circulation pump 53, the second circulation pump 54, and the heater 58), and each water-air switching valve are all designed to be automatically controlled by a program. With the assistance of an automated robotic arm, it can realize automatic loading, automatic spray cleaning, automatic air drying, and automatic material unloading. The entire process takes only about 90 seconds. It has the advantages of comprehensive functions, high degree of automation, high work efficiency, and good cleaning and drying effect. Example 3

[0067] like Figure 1As shown, the machining workpiece cleaning and drying equipment described in this embodiment includes: a frame 1, a cleaning chamber 2 provided on the frame 1; a workpiece inlet 21 communicating with the cleaning chamber of the cleaning chamber 2 is provided on the top of the cleaning chamber 2; and a top-opening switch door device 3 is provided at the workpiece inlet 21 to open or close the workpiece inlet 21.

[0068] The rotating fixture 4 is installed in the cleaning chamber of the cleaning chamber 2 via a rotating support structure, and the rotating fixture 4 is driven to rotate by a rotating drive device; the rotating fixture 4 has a fixture 41 for placing the machined workpiece 100.

[0069] A nozzle assembly is installed in the cleaning chamber. The branch pipes connected to the inlet end of each fluid medium in the nozzle assembly are connected to the spray water supply system and the compressed air supply system respectively through the corresponding water-air switching valve.

[0070] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the rotating fixture base 4 includes a rotating component 42, with a fixture 41 fixedly mounted on the top of the rotating component 42. The rotating support structure includes a fixed base 43 fixed in the mounting through hole at the bottom of the cleaning chamber 2. The vertically placed rotating component 42 is supported in the support hole of the fixed base 43 by a bearing assembly. A sealing cover 44 is fitted onto the rotating component 42, and the sealing cover 44 and the rotating component 42, as well as the sealing cover 44 and the fixed base 43, are sealed by corresponding sealing components. The top of the rotating component 42 extends beyond the top of the sealing cover 44.

[0071] The rotary drive device includes a drive motor 6 fixed on the frame 1, which is connected to a rotating component 42 extending out of the bottom of the fixed base 43 via a transmission structure. The transmission structure can be a belt drive, chain drive, etc. Here, a synchronous belt drive is used as an example. A main drive synchronous pulley 61 is fixedly mounted on the output shaft of the drive motor 6, and a driven synchronous pulley 62 is fixedly mounted on the rotating component 42 extending below the fixed base 43. A synchronous belt 63 is wound around the main drive synchronous pulley 61 and the driven synchronous pulley 62, forming a synchronous belt drive.

[0072] The nozzle assembly can be configured in several ways; five configuration options are provided here.

[0073] The first configuration of the nozzle assembly is as follows: the nozzle assembly includes a rotating nozzle assembly fixed on the rotating fixture 4 and at least one fixed nozzle assembly.

[0074] Among them, such as Figure 1 and Figure 6As shown, each fixed nozzle assembly is fixed within the cleaning chamber 2. A fixed nozzle assembly can consist of one fixed nozzle 7, multiple fixed nozzles 7, or at least one fixed spray pipe 71 with one or more fixed nozzles 7 mounted on it. The positions of each fixed nozzle 71 are arranged as needed based on the actual shape of the machined workpiece. A branch pipe is connected to the fluid medium inlet end of each fixed nozzle 7. When a fixed spray pipe 71 is present and can be directly installed on the frame 1, the inlet of the fixed spray pipe 71 is the fluid medium inlet end of the corresponding fixed nozzle assembly. When the fixed nozzle 71 or fixed spray pipe 71 is far from the frame 1, an extension fixed pipe 72 can be added. In this case, the outlet of the extension fixed pipe 72 is connected to the fluid medium inlet of the corresponding fixed nozzle 7 or the corresponding fixed spray pipe 71, and the inlet of the extension fixed pipe 72 is the fluid medium inlet end of each corresponding nozzle group. The branch pipes connected to the fluid medium inlet end of each fixed nozzle group are connected to the spray water supply system and the compressed air supply system respectively through the corresponding water-air switching valve.

[0075] like Figure 7 As shown, the structure of the rotating nozzle assembly includes: zero or at least one first nozzle 81 and zero or at least one second nozzle 82, wherein when the number of first nozzles 81 is zero, there is at least one second nozzle 82, and when the number of second nozzles 82 is zero, there is at least one first nozzle 81.

[0076] The rotating component 42 is a hollow circular tube structure, and the hollow channel in the hollow circular tube structure is the fluid medium channel of the rotating component 42; a rotary joint is installed at the inlet of the fluid medium channel of the rotating component 42, and the inlet of the rotary joint is the fluid medium inlet end of the rotary nozzle assembly.

[0077] Each second nozzle 82 is supported and fixed on the fixture 41 of the rotating fixture base 4 by a corresponding flexible universal tube 83. The flexible universal tube 83 is a tube that can be easily bent and maintained in the required shape. It can be purchased directly from the market and has the advantages of strong flexibility, flexible wiring, excellent corrosion resistance and wear resistance, long-term use in harsh environments, and low cost.

[0078] The outlet of the fluid medium channel of the rotating component 42 is connected to the fluid medium inlet of each first nozzle 81, and the fluid medium channel of the rotating component 42 is connected to the fluid medium inlet of each second nozzle 82 through each hose 84.

[0079] The branch pipes connected to the fluid medium inlet of the rotary nozzle group and the fluid medium inlet of each fixed nozzle group are connected to the spray water supply system and the compressed air supply system respectively through corresponding water-air switching valves.

[0080] At this time, when the water-air switching valves switch and connect the spray water supply system to each nozzle group, the spray water supply system is activated. The spray water supply system provides spray water to each fixed nozzle 7 in each fixed nozzle group and each first nozzle 81 and each second nozzle 82 in each rotating nozzle group. The spray water is sprayed out from each fixed nozzle 7 in each fixed nozzle group and each first nozzle 81 and each second nozzle 82 in each rotating nozzle group. At the same time, the rotating drive device is activated, driving each first nozzle 81, each second nozzle 82 and the machined workpiece 100 to rotate. The fixed nozzles 7 and the first nozzles 81 and each second nozzle 82 that rotate relative to the axis of the rotating part 42 work together to perform spray cleaning operation on the machined workpiece 100.

[0081] Similarly, when the water-air switching valves are switched to connect the compressed air supply system to the nozzle group, the compressed air supply system is activated. The compressed air supply system provides compressed air to each fixed nozzle 7 in each fixed nozzle group and each first nozzle 81 and each second nozzle 82 in each rotating nozzle group. The compressed air is ejected from each fixed nozzle 7 in each fixed nozzle group and each first nozzle 81 and each second nozzle 82 in each rotating nozzle group. At the same time, the rotating drive device is activated, driving each first nozzle 81, each second nozzle 82 and the machined workpiece 100 to rotate. The fixed nozzle 7 and each first nozzle 81 and each second nozzle 82, which rotate relative to the axis of the rotating part 42, work together to perform air drying on the machined workpiece 100.

[0082] At this time, the spraying positions of each fixed nozzle 7, each first nozzle 81, and each second nozzle 82 are adjusted according to the shape and structure of the machined workpiece 100. For example, targeted rinsing is carried out on blind holes, flow channels, threaded holes, and other parts that are prone to impurities and are not easy to clean.

[0083] The second configuration of the nozzle assembly is as follows: the nozzle assembly includes a rotating nozzle assembly fixed on the rotating fixture 4 and at least one set of fixed nozzle assemblies. The configuration of each fixed nozzle assembly can refer to the configuration of each fixed nozzle assembly in the first configuration of the nozzle assembly.

[0084] like Figure 8 As shown, the structure of the rotating nozzle assembly includes: zero or at least one first nozzle 81 and zero or at least one second nozzle 82, wherein when the number of first nozzles 81 is zero, there is at least one second nozzle 82, and when the number of second nozzles 82 is zero, there is at least one first nozzle 81.

[0085] The rotating component 42 is a hollow circular tube structure, and the hollow channel in the hollow circular tube structure is the fluid medium channel of the rotating component 42; a rotary joint is installed at the inlet of the fluid medium channel of the rotating component 42, and the inlet of the rotary joint is the fluid medium inlet end of the rotary nozzle assembly.

[0086] The fluid medium outlet of the rotating component 42 is connected to the fluid medium inlet of each of the first nozzles 81.

[0087] A flow divider box 45 with a closed cavity is fixedly mounted on the rotating component 42. A connecting pipe 46 communicating with the closed cavity of the flow divider box 45 is provided on the top of the flow divider box 45, and the connecting pipe 46 is connected to the fluid medium channel of the rotating component 42. Each second nozzle 82 is supported and fixed on the flow divider box 45 by a corresponding flexible universal tube 83. The fluid medium inlet of each second nozzle 82 is connected to the closed cavity of the flow divider box 45 through a corresponding flexible tube 84. Part of the fluid medium in the rotating component 42 is sprayed outward through each first nozzle 81, and the other part enters the flow divider box 45, and then is sprayed outward through each second nozzle 82.

[0088] The branch pipes connected to the fluid medium inlet of the rotary nozzle group and the fluid medium inlet of each fixed nozzle group are connected to the spray water supply system and the compressed air supply system respectively through corresponding water-air switching valves.

[0089] At this time, when the water-air switching valves switch and connect the spray water supply system to the nozzle group, the spray water supply system is started. The spray water supply system provides spray water to each fixed nozzle 7 in each fixed nozzle group and each first nozzle 81 and each second nozzle 82 in each rotating nozzle group. The spray water is sprayed out from each fixed nozzle 7 in each fixed nozzle group and each first nozzle 81 and each second nozzle 82 in each rotating nozzle group. At the same time, the rotating drive device is started, driving each first nozzle 81, each second nozzle 82 and the machined workpiece 100 to rotate. The fixed nozzles 7 and the first nozzles 81 and each second nozzle 82 that rotate relative to the axis of the rotating part 42 work together to spray and clean the machined workpiece 100.

[0090] Similarly, when the water-air switching valves are switched to connect the compressed air supply system to the nozzle group, the compressed air supply system is activated. The compressed air supply system provides compressed air to each fixed nozzle 7 in each fixed nozzle group and each first nozzle 81 and each second nozzle 82 in each rotating nozzle group. The compressed air is ejected from each fixed nozzle 7 in each fixed nozzle group and each first nozzle 81 and each second nozzle 82 in each rotating nozzle group. At the same time, the rotating drive device is activated, driving each first nozzle 81, each second nozzle 82 and the machined workpiece 100 to rotate. The fixed nozzle 7 and each first nozzle 81 and each second nozzle 82, which rotate relative to the axis of the rotating part 42, work together to perform air drying on the machined workpiece 100.

[0091] The main difference between the first and second configurations of the nozzle assembly lies in the number of second nozzles 82 in the rotating nozzle assembly. When the number of second nozzles 82 is small, the flow divider box 45 may not be required. When the number of second nozzles 82 is large, the flow divider box 45 should be considered.

[0092] The third configuration of the nozzle group is as follows: the nozzle group includes: a horizontal telescopic nozzle group and at least one fixed nozzle group; the configuration of each fixed nozzle group can refer to the configuration of each fixed nozzle group in the first configuration of the nozzle group.

[0093] like Figure 3 , Figure 9 and Figure 10 As shown, the structure of the horizontal telescopic nozzle assembly includes: a movable mounting base 9 set on the frame 1 by a horizontal drive device, the movable mounting base 9 being able to move horizontally under the drive of the horizontal drive device, thereby moving closer to or away from the tooling 41.

[0094] The structure of the horizontal drive device is as follows: a fixed cylinder 96 is fixedly installed on the frame 1, and the piston rod end of the fixed cylinder 96 is fixedly connected to the movable mounting seat 9.

[0095] A hollow guide rail assembly is fixedly installed on the frame 1. The hollow guide rail slide seat in the hollow guide rail assembly is fixed on the frame 1. The hollow slide rail 91 in the hollow guide rail assembly is a movable part. The hollow guide rail assembly is a component that can be directly purchased. The hollow slide rail 91 in the hollow guide rail assembly has a hollow circular tube structure. The inlet of the hollow slide rail 91 is the fluid medium inlet end of the horizontal telescopic nozzle assembly. The hollow slide rail 91 is fixedly inserted into the first horizontal through hole of the movable mounting base 9, and the outlet of the hollow slide rail 91 is connected to the connection port on the side wall of the spray main pipe 92. Several third nozzles 93 are provided on the pipe wall of the spray main pipe 92. After the movable mounting base 9 is driven by the horizontal drive device and approaches the tooling 41, each third nozzle 93 is positioned above the machined workpiece 100 placed in the tooling 41.

[0096] A guide mechanism is provided on the frame 1 to guide the horizontal movement of the movable mounting seat 9. The structure of the guide mechanism is as follows: a guide sleeve assembly 94 is fixedly installed on the frame, wherein the guide rod slide 94 in the guide sleeve assembly 94 is fixed on the frame 1, the guide rod 95 in the guide sleeve assembly 94 is a movable part, the guide sleeve assembly 94 is a mature and common structure, the guide rod 95, which moves through the guide hole of the guide rod slide 94 in the guide sleeve assembly 94, is fixedly inserted into the second horizontal through hole of the movable mounting seat 9, the axis of the guide rod 95 is parallel to the axis of the hollow slide rail 91, and the end of the guide rod 95 is fixedly connected to the side wall of the spray main pipe 92.

[0097] The branch pipes connected to the fluid medium inlet of the horizontal telescopic nozzle group and the fluid medium inlet of each fixed nozzle group are connected to the spray water supply system and the compressed air supply system respectively through the corresponding water-air switching valve.

[0098] At this time, when the water-air switching valves switch to connect the spray water supply system with the nozzle assembly, the spray water supply system is activated. The spray water supply system provides spray water to each fixed nozzle 7 and each third nozzle 93 in each fixed nozzle assembly. The spray water is sprayed out from each fixed nozzle 7 and each third nozzle 93 in each fixed nozzle assembly to perform a spray cleaning operation on the machined workpiece 100. Simultaneously, the rotary drive device is activated, causing the machined workpiece 100 to rotate.

[0099] Similarly, when the water-air switching valves switch to connect the compressed air supply system with the nozzle assembly, the compressed air supply system is activated. This system provides compressed air to each fixed nozzle 7 and each third nozzle 93 in each fixed nozzle assembly. The compressed air is then ejected from each fixed nozzle 7 and each third nozzle 93 to perform a drying operation on the machined workpiece 100. Simultaneously, the rotary drive device is activated, causing the machined workpiece 100 to rotate.

[0100] The fourth configuration of the nozzle assembly is as follows: the nozzle assembly includes: a rotary nozzle assembly fixed on the rotary fixture 4, a horizontal telescopic nozzle assembly, and at least one fixed nozzle assembly.

[0101] Among them, the fixed nozzle group and the rotating nozzle group adopt the first setting form of the nozzle group, and the horizontal telescopic nozzle group adopts the third setting form of the nozzle group, that is, the first setting form and the third setting form of the nozzle group are combined to form a new setting form of the nozzle group.

[0102] The fifth configuration of the nozzle assembly is as follows: the nozzle assembly includes: a rotary nozzle assembly fixed on the rotary fixture 4, a horizontal telescopic nozzle assembly, and at least one fixed nozzle assembly.

[0103] Among them, the fixed nozzle group and the rotating nozzle group adopt the second setting form of the nozzle group, and the horizontal telescopic nozzle group adopts the third setting form of the nozzle group, that is, the second setting form and the third setting form of the nozzle group are combined to form a new nozzle group form.

[0104] The optimal solution for the nozzle assembly is to choose the fourth and fifth configurations, as these two configurations offer the best spray cleaning and air drying efficiency.

[0105] The aforementioned machined workpiece cleaning and drying equipment combines spray cleaning and air drying functions. The starting components of each drive component, spray water supply system and compressed air supply system (the starting components of the spray water supply system are the first circulation pump 53 and the second circulation pump 54), and each water-air switching valve are all designed to be automatically controlled by a program. With the assistance of an automated robotic arm, it can realize automatic loading, automatic spray cleaning, automatic air drying and automatic material unloading. The whole process only takes about 90 seconds. It has the advantages of comprehensive functions, high degree of automation, high work efficiency and good cleaning and drying effect.
