Description

Technical Field

[0001] The invention belongs to the technical field of machinery and relates to a turntable type workpiece processing device. Background Art

[0002] Anti-oxidation treatment of workpieces refers to a protective measure taken during the processing of metal workpieces to prevent metal materials from reacting with oxygen and causing oxidative corrosion.

[0003] Anti-oxidation treatment not only extends the lifespan of workpieces but also improves their appearance, quality, and performance stability. During the manufacturing process, workpieces with internal cavities require anti-oxidation treatment. Existing treatment methods typically involve first evacuating the interior of the workpiece and then injecting an inert gas such as nitrogen.

[0004] In industrial production, due to the large number of workpieces that need to be processed, existing operations basically rely on operators to manually vacuum and nitrogen-fill individual workpieces. It can be seen that this operation method is labor-intensive and relatively inefficient.

[0005] The Chinese patent publication number CN210853686U provides a sealed anti-oxidation device for vacuuming and filling needle-shaped workpieces with nitrogen, including a tank body, a bracket device for placing the needle-shaped workpiece installed in the tank body, and a cover device sealed and connected to the upper opening of the tank body. The tank body is connected to one end of the pipeline, and the other end of the pipeline is divided into a first branch pipe and a second branch pipe; the first branch pipe is connected to a nitrogen bottle, and the first branch pipe is provided with a second diaphragm vacuum valve for controlling the nitrogen delivery in the nitrogen bottle; the second branch pipe is connected to a vacuum pump, and the second branch pipe is provided with a third diaphragm vacuum valve for controlling the vacuum pump's exhaust.

[0006] After placing the needle-shaped workpiece inside the tank, operate the vacuum pump to evacuate the tank, and then put in high-purity nitrogen to ensure that the needle-shaped workpiece can be stored for a long time without oxidation.

[0007] It can be seen that although the above patent discloses the technical solutions of vacuuming and nitrogen filling, it does not provide a solution for how to ensure stable and synchronous vacuuming and nitrogen filling during the movement of the workpiece. As a result, the problem of low operating efficiency still exists. Summary of the Invention

[0008] The object of the present invention is to provide a turntable workpiece processing device with high stability and compact structure in order to solve the above problems existing in the prior art.

[0009] The purpose of the present invention can be achieved through the following technical solutions: A turntable-type workpiece processing device comprises a frame, characterized in that it also includes a gas distribution mechanism, a conveying assembly and annular ring body one, ring body two and ring body three. The above-mentioned gas distribution mechanism is axially fixed on the frame and can rotate circumferentially.

[0013] In the above-mentioned turntable-type workpiece processing device, the pipeline 1 includes a straight-section pipe section 2 and a pipe section 1 located in the ring body 3. The two ends of the pipe section 2 are respectively fixedly connected between the main body and the ring body 3. One end of the above-mentioned pipe section 1 is connected to and communicated with the upper end of the main pipe. The above-mentioned pipe section 2 connects the pipe section 1 with the air duct 1 in the main body.

[0014] In the above-mentioned turntable workpiece processing device, the pipe section 1 has a transition section 1 extending toward the lower portion of the ring body 3, the transition section 1 is connected to and communicates with the main pipe, and the valve 1 is located at a place in the transition section.

[0015] In the above-mentioned turntable-type workpiece processing device, the pipeline 2 includes a straight-section pipe segment 4 and a pipe segment 3 located in the ring body 2. The two ends of the pipe segment 4 are respectively fixed between the main body and the ring body 2. One end of the above-mentioned pipe segment 3 is connected to and communicates with the upper end of the main pipe. The above-mentioned pipe segment 4 connects the pipe segment 3 with the air duct 2 in the main body.

[0016] In the above-mentioned turntable workpiece processing device, the pipe section three has a transition section two extending toward the lower part of the ring body two, the transition section two is connected to and communicates with the main pipe, and the above-mentioned valve two is located at the transition section two.

[0017] In the above-mentioned turntable-type workpiece processing device, the conveying assembly includes a guide rail, a hook and a chain. The above-mentioned guide rail is arc-shaped and is covered on the outer side of the ring body. The number of the hooks is several, and several hooks are connected to the chain and several hooks are evenly distributed along the length direction of the chain. The hooks are movably connected to the guide rail and the chain is used to connect with the driving member, and the chain is against the outer side of the ring body.

[0018] In the above-mentioned turntable workpiece processing device, the outer side of the guide rail has a recessed slide groove, the upper end of the hook is connected to a rotatable roller, the middle part of the hook is fixedly connected to the chain, and the lower end of the hook is a hanging part for hanging the workpiece.

[0019] In the above-mentioned turntable-type workpiece processing device, the main body is respectively composed of connection part one, connection part two and connection part three from bottom to top, and a number of connecting rods are axially evenly distributed on the outside of the main body, and the two ends of the connecting rods are respectively fixedly connected to the ring body one and the connection part one, the pipe segment two is circumferentially evenly distributed on the outside of the main body and the two ends of the pipe segment two are respectively fixedly connected to the ring body two and the connection part two, the pipe segments are circumferentially evenly distributed on the outside of the main body and the two ends of the pipe segment four are respectively fixedly connected to the ring body three and the connection part three.

[0021] Compared with the prior art, the conveying assembly in this turntable workpiece processing device has two functions: First, the workpiece is moved stably around the ring body through the conveying assembly; Secondly, since the conveying assembly is connected to the ring body three, when the conveying assembly drives the workpiece to move, the ring body three, the ring body two, the ring body two and the gas collecting and distributing mechanism can rotate together.

[0022] Port 1 is connected to an air pump. Opening valve 1 allows the pump to evacuate the workpiece's interior. Port 2 is connected to a nitrogen storage tank. Opening valve 2 allows nitrogen to be introduced into the workpiece's interior. During operation, only one of valves 1 or 2 is open, meaning that evacuating the workpiece and filling it with nitrogen are two separate steps.

[0023] Since the air inside the workpiece is stably replaced with nitrogen, the inside of the workpiece can be well protected from oxidation.

[0024] When the conveying assembly drives the workpiece to move, the ring body three and the ring body two rotate together. Therefore, when the workpiece at the conveying assembly is vacuumed or filled with nitrogen, the connector assembly connected to the workpiece will also move together.

[0025] After the workpiece has been vacuumed and filled with nitrogen, it is removed from the conveyor assembly or sent to the next process. It can be seen that the vacuuming and nitrogen filling treatments of this device can perform anti-oxidation treatment on the inner cavity of the workpiece in batches.

[0026] The degree of automation is relatively high, and the entire device relies on the power provided by the conveying component. The structure is simple and compact, and the cost of use is relatively low. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0040] like Figure 1As shown in FIG. 9 , the turntable workpiece processing device includes a frame 1, a gas collecting and distributing mechanism, a conveying assembly and an annular ring body 3, a ring body 2 4 and a ring body 3 5. The above-mentioned gas collecting and distributing mechanism is axially fixed on the frame 1 and can rotate circumferentially. The above-mentioned ring body 1 3, the ring body 2 4 and the ring body 3 5 are arranged concentrically from the inside to the outside and the three are fixedly connected to the gas collecting and distributing mechanism. The above-mentioned conveying assembly is located on the outside of the ring body 3 5. A rolling contact assembly is provided between the ring body 1 and the frame 1. A joint assembly is fixedly connected to the lower part of the ring body 3 5. The ring body 3 5 has a pipeline 1 6 connecting the joint assembly with the gas collecting and distributing mechanism, and the pipeline 1 6 has a valve 1 7 that can be opened and closed. The ring body 2 4 has a pipeline 2 8 connecting the joint assembly with the gas collecting and distributing mechanism, and the pipeline 2 8 has a valve 2 9 that can be opened and closed. The conveying assembly is used to drive the workpiece to move and the conveying assembly is connected to the ring body 3 5.

[0041] The gas distribution mechanism includes a cylindrical body 2, the lower end of which is axially fixed on the frame 1. The body 2 has independent air duct 1 3b and air duct 2 3c. The above-mentioned pipeline 1 6 is connected to air duct 1 3b, and the above-mentioned pipeline 2 8 is connected to air duct 2 3c. The upper part of the body 2 has an interface 10 connected to air duct 1 3b, and the lower part of the body 2 has an interface 2 11 connected to air duct 2 3c.

[0042] The turntable workpiece processing device is used to process a workpiece with an inner cavity structure, and its specific processing content is to perform anti-oxidation treatment on the interior of the workpiece.

[0043] The workpiece to be processed is connected to the conveying assembly, and the operator then connects the joint assembly to the inside of the workpiece through a connecting hose.

[0044] Air channel 1 (3b) in the connector assembly is connected to and communicates with the connector assembly via pipe 1 (6), and air channel 2 (3c) in the connector assembly is connected to and communicates with the connector assembly via pipe 2 (8). Pipe 1 (6) has a valve 1 (7) that can be opened and closed, and pipe 2 (8) has a valve 2 (9) that can be opened and closed.

[0045] Therefore, when valve 1 7 is opened and valve 2 9 is closed, since air channel 1 3b is used to connect to the air pump, the air in the workpiece is extracted in sequence through the connecting hose, pipe 1 6 and air channel 1 3b during the operation of the air pump, keeping the interior of the workpiece in a vacuum state.

[0046] When valve 1 7 is closed and valve 2 9 is opened, since air channel 2 3 c is connected to the nitrogen tank, the nitrogen in the nitrogen tank is sequentially delivered into the workpiece through air channel 2 3 c, pipeline 2 8 and the connecting hose. When the workpiece is filled with nitrogen, it can have a good anti-oxidation effect on the interior of the workpiece.

[0047] The connecting hose is an existing flexible pipe body, that is, the connecting hose is a commercially available part. Therefore, the technical features of the connecting hose will not be described in detail in this embodiment.

[0048] Interface 1 10 enables the air pump to be stably connected and conducted to air passage 1 3 b , and interface 2 11 enables the nitrogen tank to be stably connected and conducted to air passage 2 3 c .

[0049] The conveyor assembly has two functions: First, it is used to transport the workpiece to be processed; Second, the conveying assembly is in contact with the ring body 3 5. Therefore, when the conveying assembly moves, it can drive the ring body 3 5 to rotate. Since the ring bodies 1 3, 2 4, and 3 5 are all fixedly connected to the gas distribution mechanism, the ring bodies 1 3, 2 4, 3 5 and the gas distribution mechanism will rotate together.

[0050] The purpose of this is that when the workpiece moves at the conveying assembly, the joint assembly on the ring body 3 5 will also move together. In other words, the workpiece completes the above-mentioned vacuuming operation and nitrogen filling operation in the process of moving with the conveying assembly.

[0051] Of course, the device has a limited degree of automation, and before processing, the two ends of the connecting hose need to be manually connected to the connector assembly and the workpiece. After processing is completed, the connecting software needs to be dialed out from the workpiece.

[0052] However, the conveying component drives the workpiece to move while completing the corresponding processing operations. Although manual plugging and unplugging of the connecting pipes affects the operating efficiency, overall it still has obvious operating efficiency advantages.

[0053] The main body 2 has a transversely arranged partition 3a, and the partition 3a divides the main body 2 into two adjacent cavities. The airway 1 3b is located in the cavity above the partition 3a, and the airway 2 3c is located in the cavity below the partition 3a.

[0054] The partition 3a separates the main body 2 into two independent cavities, that is, the airway 1 3b and the airway 2 3c are two independent parts and are not connected.

[0055] Moreover, the interface 10 is located at the upper part of the body 2, and the interface 2 11 is located at the lower part of the body 2. Such a structure can also facilitate the communication between the interface 10 and the airway 1 3b, and the communication between the interface 2 11 and the airway 2 3c.

[0056] The joint assembly includes a vertically arranged main pipe 12 and a plurality of branch pipes 13 evenly distributed along the length direction of the main pipe 12. The plurality of branch pipes 13 are all connected to the main pipe 12. The upper end of the main pipe 12 is fixedly connected to the ring body 3 5.

[0057] The inner diameter of the main pipe 12 is larger than that of the branch pipe 13 , and a plurality of branch pipes 13 are provided on both sides of the main pipe 12 .

[0058] Such a structure enables the nitrogen in the main pipe 12 to be evenly distributed into each branch pipe 13 .

[0059] The pipeline 1 6 includes a straight section 2 6b and a pipe section 1 6a located in the ring body 3 5. The two ends of the pipe section 2 6b are respectively fixedly connected between the main body 2 and the ring body 3 5. One end of the above-mentioned pipe section 1 6a is connected to and communicates with the upper end of the main pipe 12. The above-mentioned pipe section 2 6b connects the pipe section 1 6a with the airway 1 3b in the main body 2.

[0060] Pipeline 16 has two functions; The two ends of the pipe section 2 6b are fixedly connected to the ring body 3 5 and the main body 2, and the ring body 3 5 and the main body 2 are indirectly fixedly connected through the pipe section 2 6b; The pipe section 1 6a and the pipe section 2 6b are connected, and finally the air passage 1 3b on the main body 2 is connected to the joint assembly.

[0061] The pipe section 1 6a has a transition section 1 6a1 extending toward the lower portion of the ring body 3 5 . The transition section 1 6a1 is connected to and communicates with the main pipe 12 . The valve 1 7 is located at the transition section 1 6a1 .

[0062] The setting of the transition section 6a1 can not only ensure the stable connection between the joint assembly and the pipe section 6a, but also ensure the stable conduction between the pipe section 6a and the joint assembly.

[0063] The pipeline 2 8 includes a straight section 4 8b and a pipe section 3 8a located in the ring body 2 4. The two ends of the pipe section 4 8b are respectively fixedly connected between the main body 2 and the ring body 2 4. One end of the above-mentioned pipe section 3 8a is connected to and communicates with the upper end of the main pipe 12. The above-mentioned pipe section 4 8b connects the pipe section 3 8a with the airway 2 3c in the main body 2.

[0064] Pipeline 2 8 has two functions; The two ends of the pipe section 4 8b are fixedly connected to the ring body 2 4 and the main body 2, and the ring body 2 4 and the main body 2 are indirectly fixedly connected through the pipe section 4 8b; Second, the pipe section three 8a and the pipe section four 8b are connected, and finally the air passage two 3c on the main body 2 is connected to the joint assembly.

[0065] The pipe section three 8a has a transition section two 8a1 extending toward the lower portion of the ring body two 4. The transition section two 8a1 is connected to and communicates with the main pipe 12. The valve two 9 is located at the transition section two 8a1.

[0066] The provision of the second transition section 8a1 not only ensures a stable connection between the joint assembly and the pipe section 3 8a, but also ensures a stable conduction between the pipe section 3 8a and the joint assembly.

[0067] In this embodiment, there are multiple connector assemblies, all of which are evenly distributed on the lower portion of the ring body 3 5. Between the ring body 3 5 and the body 2, there is a pipe section 2 6b corresponding to each connector assembly. Between the ring body 2 4 and the body 2, there is a pipe section 4 8b corresponding to each connector assembly.

[0068] The conveying assembly includes a guide rail 14, a hook 15 and a chain 16. The guide rail 14 is arc-shaped and is covered on the outside of the ring body three 5. There are several hooks 15, and several hooks 15 are connected to the chain 16 and are evenly distributed along the length direction of the chain 16. The hooks 15 are movably connected to the guide rail 14 and the chain 16 is used to connect to the driving member. The chain 16 is against the outside of the ring body three 5.

[0069] The upper portion of the hook 15 is connected to the guide rail 14 . When the chain 16 is pulled by the driving member, the hook 15 moves horizontally along the guide rail 14 .

[0070] At the same time, the chain 16 rests against the outside of the ring body 3 5. Since the chain 16 is pressed tightly against the outside of the ring body 3 5, there is sufficient friction between the two. Therefore, the chain 16 will drive the ring body 3 5 to rotate together during the movement process.

[0071] The outer side of the guide rail 14 has a concave sliding groove 14a, the upper end of the hook 15 is connected to a rotatable roller 17, the middle part of the hook 15 is fixedly connected to the chain 16, and the lower end of the hook 15 is a hanging part 15a for hanging a workpiece.

[0072] The roller 17 on the hook 15 is embedded in the slide groove 14 a, which can reduce the friction resistance between the upper end of the hook 15 and the guide rail 14 and ensure that the hook 15 can move stably along the guide rail 14.

[0073] The main body 2 is composed of connection part 1 2a, connection part 2 2b and connection part 3 2c from bottom to top. A number of connecting rods 19 are axially evenly distributed on the outside of the main body 2. The two ends of the connecting rod 19 are respectively fixedly connected to the ring body 1 3 and the connection part 1 2a. The pipe section 2 6b is circumferentially evenly distributed on the outside of the main body 2, and the two ends of the pipe section 2 6b are respectively fixedly connected to the ring body 2 4 and the connection part 2 2b. The pipe section 4 8b is circumferentially evenly distributed on the outside of the main body 2, and the two ends of the pipe section 4 8b are respectively fixedly connected to the ring body 3 5 and the connection part 3 2c.

[0074] The connecting rod 19 is connected to the connection part 1 2a, the pipe section 2 6b is connected to the connection part 2b, and the pipe section 4 8b is connected to the connection part 3 2c. This structure can effectively avoid mutual interference between the connecting rod 19, the pipe section 2 6b and the pipe section 4 8b.

[0075] The contact assembly includes contact wheels 18 movably connected to the frame 1. The contact wheels 18 are evenly distributed circumferentially with the center of the ring body 3 as the reference, and several contact wheels 18 are all against the lower part of the ring body 3.

[0076] A plurality of contact wheels 18 are fixedly attached to the frame 1 and are evenly distributed around the outside of the body 2. Each contact wheel 18 abuts against the lower portion of the ring body 3, effectively reducing frictional resistance between the ring body 3 and the frame 1.

[0077] Ultimately, it is ensured that the ring body 3 can rotate stably.

[0078] The conveying assembly in this turntable workpiece handling device has two functions: First, the workpiece is moved stably around the ring body through the conveying assembly; Secondly, since the conveying assembly is connected to the ring body three, when the conveying assembly drives the workpiece to move, the ring body three, the ring body two, the ring body two and the gas collecting and distributing mechanism can rotate together.

[0079] Port 1 is connected to an air pump. Opening valve 1 allows the pump to evacuate the workpiece's interior. Port 2 is connected to a nitrogen storage tank. Opening valve 2 allows nitrogen to be introduced into the workpiece's interior. During operation, only one of valves 1 or 2 is open, meaning that evacuating the workpiece and filling it with nitrogen are two separate steps.

[0080] Since the air inside the workpiece is stably replaced with nitrogen, the inside of the workpiece can be well protected from oxidation.

[0081] When the conveying assembly drives the workpiece to move, the ring body three and the ring body two rotate together. Therefore, when the workpiece at the conveying assembly is vacuumed or filled with nitrogen, the connector assembly connected to the workpiece will also move together.

[0082] After the workpiece has been vacuumed and filled with nitrogen, it is removed from the conveyor assembly or sent to the next process. It can be seen that the vacuuming and nitrogen filling treatments of this device can perform anti-oxidation treatment on the inner cavity of the workpiece in batches.

[0083] The degree of automation is relatively high, and the entire device relies on the power provided by the conveying component. The structure is simple and compact, and the cost of use is relatively low.

[0084] In this embodiment, in order to improve the degree of automation.

[0085] A remote control module is provided in a monitoring room far away from the turntable workpiece processing device. A controller for controlling valve one and valve two is provided at the turntable workpiece processing device. The remote control module and the controller are connected for data signals via wireless data transmission.

[0086] That is to say, after the corresponding control operation is performed on the remote control module in the monitoring room, the workpiece at the conveying component can be vacuumed or filled with nitrogen at the set position.

[0087] It can be seen that due to the large number of joint components, centralized control can not only accurately realize the switching operation of valve one and valve two, but also does not require operators to enter the working environment of the turntable workpiece processing device, thereby appropriately improving its safety.

[0088] The various technical features of the above-described embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the various technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0089] Those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present invention and are not intended to limit the present invention. Any appropriate changes and modifications to the above embodiments fall within the scope of the present invention as long as they are within the spirit of the present invention.
