Description

Technical Field

[0001] This application belongs to the field of screw sleeve processing, specifically relating to a centrifugal oil-throwing device and a screw sleeve processing production line. Background Technology

[0002] A threaded insert is a fastener that matches a stud. Its processing involves processes such as blank turning, drilling, boring, and internal threading. During drilling, a large amount of coolant and lubricant, as well as a lot of residual chips, adhere to the inside and outside of the workpiece, which will adversely affect the next step of boring (which requires a high degree of cleanliness of the workpiece). Therefore, cleaning is necessary, but manual cleaning is inefficient.

[0003] Existing technologies can remove cooling lubricant and chips using centrifugal technology. However, most existing centrifugal oil-throwing devices require the workpiece to be placed in a rotating metal basket. During operation, the workpiece is prone to collisions, causing surface damage. Furthermore, it is not easy to balance the workpiece, leading to imbalance and creating danger. Therefore, these devices are not suitable for cleaning cooling lubricant and chips from threaded sleeves. Summary of the Invention

[0004] The technical problem to be solved by this application is to provide a centrifugal oil-throwing device and a screw sleeve processing production line, which is suitable for cleaning the cooling lubricant and chips of the screw sleeve and improves the working efficiency.

[0005] In a first aspect, this application provides a centrifugal oil-spinning device, comprising:

[0006] frame;

[0007] The housing is mounted on the frame;

[0008] The centrifugal mechanism includes a driver mounted on the frame, a rotating disk rotatably mounted inside the housing, and multiple positioning structures arranged circumferentially on the rotating disk for supporting and restricting the movement of the cylindrical workpiece. The driver is drivenly connected to the rotating disk.

[0009] Optionally, the positioning structure includes a support frame, a plurality of limiting grooves disposed on the support frame for placing the columnar workpiece, and a baffle disposed on the outside of the support frame for restricting the axial movement of the columnar workpiece.

[0010] Optionally, the support frame includes multiple vertical supports, each of which has multiple limiting grooves distributed vertically, and the multiple vertical supports are distributed in a straight line from near the center of the rotating disk outward.

[0011] Optionally, the bottom surface of the limiting groove is an inclined surface used to prevent the columnar workpiece from slipping, and the limiting groove is a U-shaped groove or a V-shaped groove.

[0012] Optionally, the baffle has vertically extending oil guide grooves.

[0013] Optionally, the centrifugal oil-scraping device further includes a collection box, the rotating disk having a through hole, and a conduit leading to the collection box being provided at the through hole.

[0014] Optionally, the centrifugal oil-scraping device further includes a cover plate disposed on the top of the tank.

[0015] Optionally, the driver includes a servo motor, a stepper motor, or a geared motor, and the driver is directly connected to the rotating disk or connected via a transmission device.

[0016] Optionally, the collection box is disposed within the frame and located at the bottom of the rotating disk, and a filter screen is provided inside the collection box.

[0017] Optionally, a valve is provided near the bottom of the collection box.

[0018] Optionally, the centrifugal oil slinger also includes a pump body for extracting cooling lubricating fluid from the collection tank.

[0019] Optionally, the collection box has a cleaning port on one side and above the filter screen, and the cleaning port is provided with a removable cover.

[0020] Secondly, this application provides a threaded sleeve processing production line, including a raw material rack, a drilling machine, a centrifugal oil-throwing device, multiple lathes, a thread inspection device, and a gantry robot extending from the raw material rack to the thread inspection device, arranged in sequence.

[0021] Optionally, the threaded sleeve processing production line further includes multiple workpiece temporary storage devices respectively disposed between each processing node. The workpiece temporary storage device includes a bracket, a material box disposed on the bracket, and a chain conveyor line disposed on one side of the bracket. The chain conveyor line is provided with at least two guide plates distributed in an inverted V-shape, and a proximity switch is provided at the end of the chain conveyor line.

[0022] The beneficial effects of this application are:

[0023] In the first aspect, the centrifugal oil-throwing device provided in this application uses a driver to drive a rotating disk to provide centrifugal force. Multiple positioning structures disperse and position multiple cylindrical workpieces, avoiding collisions between the cylindrical workpieces. Moreover, the positions of the positioning structures are fixed, making them less prone to imbalance and improving safety. Under the action of centrifugal force, the attached cooling lubricant and residual chips are thrown into the chamber, improving work efficiency.

[0024] Secondly, the threaded sleeve machining production line provided in this application typically uses cutting fluid during the threaded sleeve machining process, especially in drilling and turning operations, to reduce cutting temperature, decrease cutting force, and improve the surface finish. However, cutting fluid may remain on the threaded sleeve surface and may be mixed with impurities such as metal shavings. The centrifugal oil-throwing device uses high-speed rotation to generate centrifugal force, which removes the cutting fluid and impurities from the threaded sleeve surface, thereby ensuring the cleanliness of the threaded sleeve during subsequent machining and inspection processes.

[0033] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0034] like Figure 1-5 As shown, the centrifugal oil-throwing device provided in this application includes: a frame 100, a housing 200, and a rotating centrifugal mechanism; wherein, the housing 200 is mounted on the frame 100; the rotating centrifugal mechanism includes a driver 310 mounted on the frame 100, a rotating disk 320 rotatably mounted inside the housing 200, and a plurality of positioning structures 330 circumferentially mounted on the rotating disk 320 for supporting and restricting the movement of columnar workpieces, and the driver 310 is drivenly connected to the rotating disk 320.

[0035] Compared with the prior art, the centrifugal oil-throwing device 10 provided in this application has a driver 310 driving the rotating disk 320 to rotate to provide centrifugal force, and multiple positioning structures 330 disperse and position multiple columnar workpieces to avoid collisions between columnar workpieces. Moreover, the position of the positioning structure 330 is fixed and not easy to become unbalanced, which improves safety. Under the action of centrifugal force, the attached cooling lubricant and residual chips are thrown into the box 200, which improves working efficiency.

[0036] In one possible implementation, such as Figure 5 As shown, the positioning structure 330 includes a support frame 331, multiple limiting grooves 332 disposed on the support frame 331 for placing the cylindrical workpiece, and a baffle 333 disposed on the outside of the support frame 331 for restricting the axial movement of the cylindrical workpiece. Specifically, the multiple limiting grooves 332 are in one or more groups, with each group of multiple limiting grooves 332 at the same horizontal height, jointly supporting the cylindrical workpiece and forming a semi-enclosed support state. During centrifugal rotation, the cylindrical workpiece abuts against the baffle 333 under the action of centrifugal force, thereby ensuring the stability of the cylindrical workpiece and making it easier to remove.

[0037] In one possible implementation, the support frame 331 includes multiple vertical supports, each with multiple vertically distributed limiting grooves 332. These vertical supports are linearly distributed outwards from the center of the rotating disk 320. Specifically, the vertical supports are fixed to the rotating disk 320 by bolts or welding. The rotating disk 320 has a disc structure, and its center is connected to the driver 310 via a bearing and a rotating shaft. The outer edge of the rotating disk 320 engages with the frame 100 via bearing rings. The support frame 331, composed of multiple vertical supports, reduces its weight, thus lessening the load on the driver 310. This improves structural stability and increases rotational speed. The multiple vertically distributed limiting grooves 332 allow multiple columnar workpieces to be mounted on a single support frame 331, improving space utilization.

[0038] In one possible implementation, the bottom surface of the limiting groove 332 is an inclined surface 3321 for preventing the columnar workpiece from slipping out, and the limiting groove 332 is a U-shaped groove or a V-shaped groove. Specifically, the height of the inclined surface 3321 gradually increases from the inside to the outside of the limiting groove 332, and the columnar workpiece is always in contact with the inside of the limiting groove 332 under the guidance of the inclined surface 3321, thus avoiding detachment.

[0039] In one possible implementation, the baffle 333 has vertically extending oil guide grooves 3331. Specifically, the baffle 333 can be fixed to the outside of the outermost vertical support by screws or welding, and one or more oil guide grooves 3331 are located on the side of the baffle 333 facing the center of the rotating disk 320. During centrifugal rotation, the ejected cooling lubricant can flow out quickly through the oil guide grooves 3331.

[0040] In one possible implementation, the centrifugal oil slinger 10 further includes a collection tank 400, and the rotating disk 320 has a through hole 321, through which a conduit leading to the collection tank 400 is provided. Specifically, the cooling lubricating fluid flows into the collection tank 400 through the through hole 321 and the conduit under the action of gravity.

[0041] In one possible implementation, the centrifugal oil-throwing device 10 also includes a cover plate 210 disposed on the top of the housing 200. Specifically, during the centrifugal oil-throwing process, oil, and even detached parts, may be thrown out under high-speed rotation. The cover plate 210 serves as the primary physical barrier for operators and the surrounding environment, preventing these high-speed splashes from causing personal injury or equipment damage. The cover plate 210 completely encloses the high-speed rotating positioning structure 330, preventing operators' hands, tools, or other foreign objects from accidentally entering the rotating area, thus avoiding serious mechanical injury accidents. The cover plate 210 can be a single-door or double-door structure, fixed to the top edge of the housing 200 by one or more hinges, or it can be placed directly on the top opening of the housing 200 with multiple bolt holes evenly distributed around its perimeter. Tightening the bolts or screws presses the cover plate 210 against the flange or sealing surface of the housing 200. Alternatively, it can be secured around the cover plate 210 using quick-release clamps, rotary locks, eccentric cam locks, lever-type locks, or other devices evenly distributed around the cover plate 210. The cover plate 210 can be quickly tightened or loosened by operating the handle or knob.

[0042] In one possible implementation, the driver 310 includes a servo motor, a stepper motor, or a geared motor, and the driver 310 is directly connected to the rotating disk 320 or connected via a transmission device.

[0043] In one possible implementation, a collection box 400 is disposed within the frame 100 and located at the bottom of the rotating disk 320, and a filter screen 410 is disposed within the collection box 400. Specifically, the filter screen 410 includes types such as a mesh filter, a multi-layer disc filter, and a magnetic filter.

[0044] In one possible implementation, a valve 440 is located near the bottom of the collection tank 400. Specifically, the valve 440 includes a ball valve, a butterfly valve, etc., and is driven manually, pneumatically, or electrically, for draining the cooling lubricant from the collection tank 400.

[0045] In one possible implementation, the collection box 400 has a cleaning port 420 on one side and above the filter screen 410, and the cleaning port 420 is provided with a removable cover 430. The cover 430 can be opened to clean metal shavings from the filter screen 410, and can also be used to install or remove the filter screen 410.

[0046] In one possible implementation, the centrifugal oil slinger 10 further includes a pump body 500 for extracting cooling and lubricating fluid from the collection tank 400. Specifically, the inlet of the pump body 500 is connected to a connecting pipe into the collection tank 400, and the inlet of the pump body 500 is connected to a connecting pipe into the cooling and lubricating fluid system, so that the collected cooling and lubricating fluid can be reused.

[0047] Secondly, such as Figure 6As shown, this application provides a threaded insert processing production line, including a raw material rack 20, a drilling machine 30, a centrifugal oil-throwing device 10, multiple lathes 40 arranged sequentially, a thread inspection device 50, and a gantry robot 60 extending from the raw material rack 20 to the thread inspection device 50. Specifically, the raw material rack 20 is used to hold the threaded insert raw materials to be processed. First, the gantry robot 60 picks up the threaded insert raw materials from the raw material rack 20 and transports them to the drilling machine 30. The drilling machine 30 performs a drilling operation on the threaded insert raw materials, which is a key step in threaded insert processing, creating conditions for subsequent thread processing and other processes. After drilling is completed, the robot transports the threaded insert to the centrifugal oil-throwing device 10. The surface of the processed threaded insert may be contaminated with some cutting fluid and other impurities, which can be removed by the centrifugal oil-throwing device 10. Subsequently, the robot continues to send the threaded insert sequentially to the multiple lathes 40. Further processing is performed on the lathes 40, such as turning external threads, internal threads, etc. The lathe 40 can precisely control parameters such as cutting depth and feed rate to ensure that the thread dimensions of the screw sleeve meet the requirements. The machined screw sleeve is transported to the thread inspection equipment 50 by the gantry robot 60. The thread inspection equipment 50 can accurately inspect the threads of the screw sleeve, including parameters such as thread diameter, pitch, and tooth profile. The inspection equipment feeds back the inspection results to the control system. If the screw sleeve thread meets the standard, subsequent processes, such as packaging, continue; if it does not meet the standard, it will be rejected or reworked. The entire process, coordinated by the gantry robot 60, completes each step sequentially, achieving automated machining and production of screw sleeves.

[0048] In the machining of threaded inserts, especially during drilling and turning operations, cutting fluid is typically used to reduce cutting temperature, decrease cutting force, and improve the surface finish. However, cutting fluid residue can remain on the surface of the threaded insert and may contain impurities such as metal shavings. The centrifugal oil-throwing device 10 uses high-speed rotation to generate centrifugal force, which removes cutting fluid and impurities from the surface of the threaded insert, thus ensuring the cleanliness of the threaded insert during subsequent machining and inspection processes.

[0049] In one possible implementation, such as Figure 7As shown, the threaded sleeve processing production line also includes multiple workpiece temporary storage devices 70 respectively set between each processing node. Each workpiece temporary storage device 70 includes a support 710, a material box 720 set on the support 710, and a chain conveyor 730 set on one side of the support 710. The chain conveyor 730 is equipped with at least two guide plates 740 arranged in an inverted V-shape, and a proximity switch is installed at the end of the chain conveyor 730. Specifically, after a threaded sleeve processing step is completed, the gantry robot 60 places it into the material box 720 of the workpiece temporary storage device 70. The chain conveyor 730 starts working under power drive, conveying the material box 720 forward. The guide plates 740 on the chain conveyor 730 are arranged in an inverted V-shape; this design guides and stabilizes the material box 720, preventing it from shifting or tipping over during transport. When the material box 720 is conveyed to the end of the chain conveyor 730, the proximity switch activates. A proximity switch is a sensor that detects the position of an object without contact. When the material box 720 approaches within a certain distance, the proximity switch detects its presence and sends a signal. This signal can control subsequent actions, such as instructing the gantry robot 60 to pick up the threaded sleeve from the material box 720 and send it to the next processing node, or controlling the chain conveyor 730 to pause its transport, awaiting processing by subsequent processes. It acts as a buffer and storage mechanism between processing nodes. Since the processing times for different processes may not be exactly the same—for example, the time it takes for the drilling machine 30 to complete drilling a threaded sleeve may differ from the time it takes for the lathe 40 to complete turning a threaded sleeve—the workpiece temporary storage device 70 can temporarily store threaded sleeves that have completed the previous process, avoiding production interruptions due to time mismatches between preceding and subsequent processes, thus improving the continuity and efficiency of the entire production line.
