Description

Technical Field

[0001] This invention relates to the field of coating technology, and more specifically, to a rotary core-filling component processing and feeding coating device. Background Technology

[0002] Rotary core fillers are supporting components of rotary systems in the oil drilling industry. Installed in the central square hole of the drilling rotary table, they are mainly used to support the square drill pipe and drill string structure and transmit rotational torque. They are key load-bearing components that withstand heavy loads, impacts, and friction during drilling operations. These components are constantly exposed to drilling mud, formation moisture, salt spray, and various corrosive media in outdoor oilfield operations. The exposed non-precision metal surfaces are highly susceptible to oxidation and corrosion. Therefore, it is necessary to use coating equipment to professionally coat the non-fitting areas on the outside. By forming a protective coating on the workpiece surface, the contact between corrosive media and the metal substrate is isolated, achieving the core protective effect of corrosion and rust prevention. At the same time, it can improve the uniformity of the component's appearance and extend its service life under complex working conditions.

[0003] When the existing coating equipment is working, the turntable core workpiece to be coated is first transported to the coating station by the feeding mechanism and positioned and locked. Then, the coating mechanism sprays the atomized paint evenly onto the exposed surface of the workpiece according to the preset motion trajectory, ensuring that a uniform and continuous coating is formed on each vertical surface and around the holes of the workpiece. After the coating is completed, the workpiece enters the curing station through the feeding mechanism to complete the coating drying.

[0004] However, existing coating equipment does not provide adequate shielding for non-coated areas during coating. The inner cavity of the rotary core is a precision-fitting surface and does not require coating. Coating the entire surface before machining the inner cavity would directly compromise dimensional and fit accuracy. Therefore, this area must be shielded before coating. Using a film-based shielding method is problematic in several ways: first, the process is cumbersome and time-consuming; second, there is no transition area between the metal inner cavity and outer surface of the rotary core, making it difficult to select a suitable film-attachment area; and third, the high surface finish of the metal inner cavity means insufficient adhesion, leading to edge lifting and detachment, and the adhesive is difficult to remove. Using a rigid mold shielding method, the contact surface between the workpiece and the mold cannot be completely sealed. During coating, paint can seep into the inner cavity through gaps, contaminating the precision surface and affecting subsequent assembly accuracy, increasing rework costs and product defect rates. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a rotary core-filling component processing, feeding and coating device.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a rotary core-filling component processing and coating device, comprising a coating robot and a positioning component, wherein the positioning component is disposed on one side of the coating robot, the top of the positioning component is provided with a core-filling body for coating processing, and the bottom of the core-filling body is provided with two lower end sections, and the positioning component is used to position the core-filling body.

[0007] The contouring assembly comprises two sets, both of which slide on top of the positioning assembly. The contouring assembly is used to assist in the positioning and placement of the core body. Each set includes a contouring block that slides on top of the positioning assembly and an annular groove formed on the outer wall of the contouring block. Two clamps slide on the outer wall of the annular groove, and an adjustment mechanism connects the two clamps. Both sets of contouring assemblies also include a roller with folded paint-absorbing cotton wound on it. One end of the paint-absorbing cotton is fitted onto the outer wall of the contouring block and extends between the clamps and the contouring block. The two clamps lock the paint-absorbing cotton in place. Both ends of the core body are attached to the outer walls of the two paint-absorbing cotton pieces. The paint-absorbing cotton is used to seal and absorb paint at the point where the ends of the core body meet the contouring block.

[0008] By adopting the above technical solution, by setting up paint-absorbing cotton, which covers the outer wall of the contour block, when the contour block is inserted into the tapered hole at the end of the turntable core to complete the positioning and clamping, the paint-absorbing cotton is pressed and filled by the workpiece end face to absorb the paint mist that seeps in, thereby improving the shielding and sealing of the inner cavity and preventing the precision surface of the inner cavity from being contaminated by the paint.

[0009] By setting up rollers, clamps, and adjustment mechanisms, when the paint-absorbing cotton wrinkles due to clamping friction, the operator, after positioning the contour block and the core body, pulls one end of the paint-absorbing cotton. This flattens the paint-absorbing cotton that has slipped at the contact point between the contour block and the core body, eliminating the obstruction of the paint-absorbing cotton wrinkles on the coating area of ​​the workpiece end. When the paint-absorbing cotton is saturated in the used section, the operator releases the adjustment mechanism, causing the paint-absorbing cotton to be released from locking. Then, the paint-absorbing cotton is pulled out of the saturated position, and the clean section moves to the contact point between the contour block and the core body. After the clamp locks the paint-absorbing cotton, coating continues, thus achieving the effect of continuous feeding and reuse of paint-absorbing cotton and reducing replacement costs.

[0010] The present invention is further configured such that: a limiting groove is provided at the top four corners of the positioning component, and every two limiting grooves are correspondingly provided with a clamp, and a connecting block slides inside each limiting groove, and the connecting block is connected to the end of the corresponding clamp.

[0011] The present invention is further configured such that: the positioning component includes a placement platform installed on the top of the painting table, the limiting groove is opened on the top of the placement platform, the top shape of the placement platform is adapted to the bottom contour shape of the central hollow position of the core body, the two lower end sections are suspended, the top of the placement platform has two grooves, the inside of the grooves is equipped with guide rails, the top of the guide rails is slidably equipped with sliders, two sets of contouring components are correspondingly arranged with the two sliders, the contouring components are installed on the top of the corresponding sliders, and the contouring blocks in each set of contouring components are in contact with the top surface of the placement platform.

[0012] The present invention is further configured such that: a locking handle is provided on the top of the slider, a threaded hole is provided on the top of the slider, the bottom end of the locking handle is threadedly connected to the threaded hole, and the bottom end of the locking handle passes through the threaded hole and fits against the top of the guide rail.

[0013] The present invention is further configured such that: a step is installed on the outside of the placement platform, and a paint mist felt is provided on the top of the step and below the lower end section.

[0014] The invention is further configured such that a groove is provided at the top of the step and below the two lower end sections, the groove being used to place the paint mist felt in a contoured manner.

[0015] The invention is further configured such that the tank is V-shaped and the paint mist felt is located directly below the lower end section.

[0016] The present invention is further configured such that: a partition is connected to the top of the step and to one side of the groove, and the top of the partition is spaced apart from the bottom surface of the lower end section.

[0017] The invention is further configured such that: the inner bottom wall of the groove is provided with through holes at equal intervals, and the through holes are arranged vertically downward through the step.

[0018] By adopting the above technical solution, a tank is set up and filled with paint mist felt. During the coating process, the dripping paint is absorbed and excess paint is discharged through the through holes, reducing the amount of paint accumulation in the tank. The baffle blocks the paint mist splashing from the side, thereby eliminating the obstruction of paint absorbent cotton wrinkles, extending the service life of consumables, and reducing the difficulty of equipment cleaning and maintenance.

[0019] The present invention is further configured such that: the outer cover of the positioning component and the painting robot is provided with a painting chamber, a painting table is installed inside the painting chamber, the positioning component is installed on the top of the painting table, a feeding channel is provided on one side of the painting chamber, and infrared sensing mechanisms are installed on both sides of the feeding channel.

[0020] In summary, this application includes at least one of the following beneficial technical effects: (1) By setting paint-absorbing cotton, the paint-absorbing cotton covers the outer wall of the contour block. When the contour block is inserted into the tapered hole at the end of the turntable core to complete the positioning and clamping, the paint-absorbing cotton is pressed and filled by the workpiece end face to absorb the paint mist that seeps in, thereby improving the shielding and sealing of the inner cavity and avoiding the contamination of the precision surface of the inner cavity by the paint.

[0021] (2) By setting up rollers, clamps and adjustment mechanisms, when the paint absorbent cotton wrinkles due to clamping friction, the worker pulls one end of the paint absorbent cotton after positioning the contour block and the core body. This causes the paint absorbent cotton with sliding wrinkles at the contact position between the contour block and the core body to be flattened, eliminating the obstruction of the paint absorbent cotton wrinkles to the coating area at the end of the workpiece. When the paint absorbent cotton is saturated in the usage section, the worker releases the adjustment mechanism, causing the paint absorbent cotton to be released from locking. Then, the paint absorbent cotton is pulled out of the saturated position, and the clean section moves to the contact position between the contour block and the core body. After the clamp locks the paint absorbent cotton, the coating continues, thereby achieving the effect of continuous feeding and reuse of the paint absorbent cotton and reducing replacement costs.

[0022] (3) By setting up a tank and filling it with paint mist felt, the paint that drips during the painting process is absorbed. Excess paint is discharged through the through holes, reducing the amount of paint accumulation in the tank. The baffle blocks the paint mist splashed from the side, thereby eliminating the folds of the paint absorbent cotton, extending the service life of consumables, and reducing the difficulty of cleaning and maintaining the equipment.

[0023] (4) When painting with turntable cores of different sizes, the slider moves horizontally along the guide rail to adjust the distance between the two sets of contouring components, thereby achieving the positioning and masking requirements of multiple core body sizes and reducing tooling changeover costs.

[0039] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0040] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0041] Please see Figures 1-14 The present invention provides the following technical solutions: Example 1, see Figures 1-3A rotary core-filling component processing and coating device includes a coating robot 3 and a positioning component 5. The positioning component 5 is disposed on one side of the coating robot 3. The top of the positioning component 5 is provided with a core-filling body 10 for coating processing. The bottom of the core-filling body 10 is provided with two lower end sections 101. The positioning component 5 is used to position the core-filling body 10. The two lower end sections 101 of the core-filling body 10 are arranged downwards. The coating robot 3 forms a uniform and continuous coating on the outer surface area H of the core-filling body 10, the area around the hole E, and the surface of the lower end sections 101.

[0042] See Figure 1 and Figure 2 The positioning component 5 and the painting robot 3 are equipped with a painting chamber 1 on their outer cover. The painting table 4 is installed inside the painting chamber 1. The positioning component 5 is installed on the top of the painting table 4. A feeding channel is set on one side of the painting chamber 1. Infrared sensing mechanisms 2 are installed on both sides of the feeding channel. The painting chamber 1 isolates the painting operation area from the outside world to avoid the spread of paint mist and pollution of the workshop environment. When feeding, the external feeding mechanism loads the core body 10 that needs to be painted through the feeding channel. The infrared sensing mechanism 2 can detect the entry and exit status of personnel or workpieces at the feeding channel to realize the start and stop control of the painting operation.

[0043] See Figures 2-4 The positioning component 5 includes a placement platform 51 mounted on top of the painting station 4. The top shape of the placement platform 51 matches the bottom contour shape of the central hollowed-out position of the core filler body 10. After the core filler body 10 is placed on top of the placement platform 51, its two lower end sections 101 are suspended in the air. The placement platform 51 provides initial support for the core filler body 10 by matching its contoured top surface with the hollowed-out bottom surface of the core filler body 10. The suspended lower end sections 101 prevent the placement platform 51 from obstructing the lower end sections 101 to be painted, ensuring the integrity of the painting in the section area.

[0044] See Figures 4-7 The top of the placement platform 51 is provided with two sets of contouring components 6. The contouring components 6 are used to assist in the positioning and internal cavity shielding of the core body 10. The core body 10 can be covered by the two sets of contouring components 6. The two sets of contouring components 6 respectively block the arc-shaped openings at both ends of the core body 10. The bottom opening of the core body 10 is shielded by the placement platform 51, so that the internal cavity of the core body 10 is isolated from the external spraying area. The coating robot 3 sprays the exposed outer surface area H, the area around the hole E and the lower section 101 of the core body 10 to form a uniform and continuous coating.

[0045] Specifically, two sets of contouring components 6 extend into the inner cavity from both ends of the core body 10, and work together with the placement stage 51 to seal all the inner cavity openings of the workpiece, preventing paint mist from entering the inner cavity of the workpiece during the spraying process and contaminating the precision inner surface. At the same time, the contouring components 6 play a radial and axial auxiliary positioning role for the workpiece, improving the stability of the core body 10 clamping.

[0046] In Example 2, existing coating equipment suffers from poor shielding of non-coating areas during coating. Using film-based masking is cumbersome and time-consuming, and the high surface smoothness of the metal inner cavity of the rotary core makes the film adhesion insufficient, leading to edge lifting and detachment. Furthermore, the adhesive adhering to the inner cavity surface is difficult to remove. Therefore, workers use contour molds for hard masking. However, achieving a complete seal between the workpiece and the mold is challenging, allowing paint to seep into the inner cavity through gaps during coating, contaminating precision surfaces. This affects subsequent assembly accuracy, increases rework costs and product defect rates. Moreover, existing contour molds have poor versatility, only adapting to workpieces of a single size.

[0047] For this purpose, please refer to Figure 2 and Figure 4 Two grooves 53 are provided on the top of the placement platform 51. A guide rail 54 is installed inside the groove 53. A slider 55 slides on the top of the guide rail 54. Two sets of contouring components 6 are set corresponding to the two sliders 55. The contouring components 6 are installed on the top of the corresponding sliders 55. By sliding the two sets of contouring components 6 horizontally, the distance can be adjusted so that the two sets of contouring components 6 can be adapted to the positioning and masking of turntable cores of different sizes.

[0048] See Figure 2 The top of the slider 55 is provided with a locking handle 56. The top of the slider 55 has a threaded hole. The bottom end of the locking handle 56 is threadedly connected to the threaded hole. After the bottom end of the locking handle 56 passes through the threaded hole, it fits against the top of the guide rail 54. Through the threaded drive of the locking handle 56, after the slider 55 is adjusted to the target position, the slider 55 can be pressed and fixed on the guide rail 54 to prevent the contour component 6 from being displaced by external force during the spraying process, and to ensure the stability of the positioning and masking of the core body 10.

[0049] See Figure 4 and Figure 5 Both sets of contouring components 6 include contouring blocks 61 that slide on the top of positioning components 5. The central cavity of the core body 10 is composed of two conical holes. The top of the contouring block 61 is also adapted to be a conical surface. When it is necessary to position the core body 10, simply insert the contouring block 61 into the corresponding conical hole. The insertion depth is determined by the diameter of the conical hole until the end edge of the conical hole fits against the conical surface of the outer wall of the corresponding contouring block 61. At this time, both ends of the core body 10 are blocked, and during the painting process, the paint cannot enter the interior of the core body 10.

[0050] See Figures 4-8 The outer wall of the contour block 61 is covered with paint-absorbing cotton 64. Both ends of the core body 10 are attached to the outer wall of the two paint-absorbing cotton 64. The paint-absorbing cotton 64 is used to fill the gap between the end of the core body 10 and the conical surface of the contour block 61, and absorb the paint that seeps into the gap.

[0051] Specifically, the paint-absorbing cotton 64 is a flexible sealing layer, mainly made of flame-retardant polyester fiber. It can fill the gap between the rigid conformal block 61 and the end face of the core body 10, make up for the sealing defects of the hard shield, and improve the overall sealing performance. At the same time, the paint-absorbing cotton 64 can absorb a small amount of paint mist that seeps into the gap, further preventing the paint from penetrating into the inner cavity of the workpiece and avoiding the contamination of the precision surface of the inner cavity of the core body 10 by the paint.

[0052] See Figures 4-7 A step 52 is installed on the outside of the placement platform 51. A paint mist felt is placed on the top of the step 52 and below the lower section 101. A groove 7 is opened on the top of the step 52 and below the two lower sections 101. The groove 7 is used to place the paint mist felt in a V-shape. The paint mist felt is directly below the lower section 101. The groove 7 can embed and position the paint mist felt to prevent it from shifting when touched. The paint mist felt is facing the lower section 101 of the workpiece and can absorb the excess paint that flows down from the lower section 101 to prevent the paint from splashing back and contaminating the already sprayed area of ​​the core body 10.

[0053] See Figures 4-7 A partition 8 is connected to the top of the step 52 and to one side of the tank 7. The top of the partition 8 is spaced apart from the bottom surface of the lower section 101. Multiple through holes 9 are equidistantly opened on the inner bottom wall of the tank 7. The through holes 9 are set vertically downward through the step 52. The partition 8 can block the paint mist splashed from the side. The tank 7 can collect the paint that seeps out after being absorbed by the paint mist felt to the bottom of the tank. Excess paint is discharged to the outside for collection through the bottom through holes 9 to avoid paint saturation in the tank 7.

[0054] Specifically, the guide rail 54 and the slider 55 cooperate to drive the two sets of contour blocks 61 to slide and adjust the spacing along the axis. The self-centering cooperation between the conical contour block 61 and the conical hole of the core body 10 is used to achieve adaptive centering, positioning and sealing of the core body 10 of different sizes. At the same time, flexible paint-absorbing cotton 64 is set on the outer wall of the contour block 61. The paint-absorbing cotton 64 fills the gap between the contour block 61 and the hard contact surface at the end of the core body 10. During the painting process, the paint-absorbing cotton 64 absorbs a small amount of paint that seeps into the gap. That is, while forming a hard shield, the paint-absorbing cotton 64 is used to softly seal the gap, preventing the paint from seeping into the inner cavity from the gap, so that the precision surface will not be contaminated by the paint. A trough 7 and a paint mist felt are set below the lower section 101 to receive the dripping paint. The excess paint collected is discharged and collected through the through hole 9.

[0055] In Example 3, after the paint-absorbing cotton 64 is fitted onto the outer wall of the contour block 61, when the two sets of contour blocks 61 slide towards each other to clamp the core body 10, relative friction occurs between the paint-absorbing cotton 64 and the end face of the workpiece. This can easily cause the paint-absorbing cotton 64 to be dragged and wrinkled. The wrinkles accumulate at the end of the core body 10, which will block the spraying area at the end of the workpiece and thus affect the uniformity of the coating.

[0056] For this purpose, please refer to Figures 4-13 An annular groove 611 is formed on the outer wall of the contour block 61. The contour block 61 fits against the top surface of the placement platform 51. Two clamps 62 slide on the outer wall of the annular groove 611. An adjustment mechanism 63 is connected between the two clamps 62. The adjustment mechanism 63 is used to adjust the tightness of the two clamps 62 to achieve locking and releasing. Specifically, the adjustment mechanism 63 can be composed of a square tube and a locking bolt. The ends of the two clamps 62 pass through the inside of the square tube, and then the clamps 62 are locked inside the square tube by the locking bolt. The two sets of contouring components 6 also include a roller 65, and as shown in the figure. Figure 14 As shown, the paint-absorbing cotton 64 is folded, and the folded paint-absorbing cotton 64 is wound up on the roller 65.

[0057] The annular groove 611 provides sliding guidance and circumferential limit for the clamp 62. The adjustment mechanism 63 can control the opening and closing of the two clamps 62 to realize the clamping and locking and relaxation of the paint absorbent cotton 64. The roller 65 is used to store spare lengths of paint absorbent cotton 64 to realize continuous feeding of the paint absorbent cotton 64 without frequent overall disassembly and replacement.

[0058] like Figure 14As shown, after the paint-absorbing cotton 64 is released from the roller 65, it opens in a fan shape, meaning that the free end of the paint-absorbing cotton 64 can circumferentially wrap around the conical surface of the contour block 61, extending and embedding into the annular groove 611 between the clamp 62 and the outer wall of the contour block 61. The two clamps 62 apply uniform pressure to the paint-absorbing cotton 64 radially, thereby locking and fixing the paint-absorbing cotton 64. At the four corners of the top of the placement platform 51 of the positioning component 5, there are corresponding elongated limiting grooves 66. The two limiting grooves 66 on the same side are set one-to-one with the two ends of the clamps 62. Each limiting groove 66 is fitted with a sliding connecting block 67. The top of the connecting block 67 is fixedly connected to the end of the corresponding clamp 62. The clamps 62 press radially to adhere the paint-absorbing cotton 64 to the contour block 61. The outer wall surface restricts the circumferential rotation and axial movement of the paint-absorbing cotton 64. When the two sets of contour blocks 61 slide and clamp the core body 10 towards each other, the paint-absorbing cotton 64 will not be dragged and displaced due to the contact friction with the end face of the workpiece, and will not accumulate wrinkles. This avoids the problem of wrinkles blocking the area to be sprayed at the end of the workpiece from the root. At the same time, the connecting block 67 cooperates with the limiting groove 66, so that the clamp 62 can be adjusted axially synchronously with the contour block 61, and always maintain the locking state of the paint-absorbing cotton 64. It is suitable for turntable core workpieces with different axial dimensions. The side wall of the limiting groove 66 restricts the circumferential deflection of the connecting block 67, thereby restricting the circumferential rotation of the clamp 62, ensuring that the locking position is stable and will not loosen or shift due to the impact of paint mist airflow or external force of workpiece clamping during the spraying process.

[0059] Specifically, when the two sets of contour blocks 61 slide towards each other, they complete the self-centering positioning of the core body 10 through the conical surface cooperation. After the paint-absorbing cotton 64 is deformed by pressure and fills the gap between the end of the core body 10 and the conical surface of the contour block 61, the operator can first loosen the adjustment mechanism 63 to release the locking state of the clamp 62, and pull the free end of the paint-absorbing cotton 64 along the axial direction of the contour block 61 to flatten the local wrinkles caused by the squeezing friction during the clamping process, so that the paint-absorbing cotton 64 is tightly attached to the outer wall of the contour block 61. Then, tighten the adjustment mechanism 63 to drive the two clamps 62 to radially close, and press and lock the paint-absorbing cotton 64 again to eliminate the wrinkles and protrusions of the paint-absorbing cotton 64, ensuring that there is no excess obstruction in the area to be coated at the end of the workpiece, and ensuring the uniformity of the coating on the end face.

[0060] After multiple batches of workpiece painting operations are completed, and the sealed area where the paint-absorbing cotton 64 contacts the core body 10 becomes saturated or contaminated with excessive cured paint, there is no need to completely disassemble and replace the paint-absorbing cotton 64. The operation can be performed with the contouring component 6 unloaded. First, the painted core body 10 is removed. Then, the operator loosens the adjustment mechanism 63 to release the locking of the clamp 62, and continuously pulls the free end of the paint-absorbing cotton 64 axially. The spare paint-absorbing cotton 64, originally folded and wound on the roller 65, will be released and unfolded with the pulling force. As the paint-absorbing cotton 64 is fed at a uniform speed, the area originally in contact with the core body 10... The contaminated cotton section at the 0-adhesion position is gradually pulled to the outside away from the conformal adhesion area, while the clean, brand-new cotton section is pulled to the corresponding adhesion and sealing position of the conformal block 61 and the core body 10. After adjusting to the target position, the clamp 62 is tightened again to resume normal painting operation. This method extends the overall service life of a single roll of paint-absorbing cotton 64, reduces the frequency of disassembly and replacement of consumables, and the feed adjustment of paint-absorbing cotton 64 does not require disassembly of the main structure of the conformal block 61, avoiding the positioning accuracy deviation caused by repeated disassembly and assembly, and ensuring the consistency of sealing effect and coating quality of different batches of workpieces.

[0061] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
