Description

Technical Field

[0001] This invention belongs to the field of spraying equipment, and specifically relates to a spraying device for the casing of a gas generator set. Background Technology

[0002] To improve the weather resistance, corrosion resistance, and appearance of the gas generator set casing, delay casing aging and corrosion, and extend equipment service life, the casing surface needs to be professionally sprayed during the production process.

[0003] Unlike conventional square or circular shell structures, gas generator set casings are designed to accommodate internal unit assembly, airflow, and heat dissipation. They feature a multi-segment frustum-shaped irregular structure with regularly varying cross-sectional dimensions and radial curvature along the axial direction. Lacking a uniform and regular spraying reference surface, this places higher demands on the uniformity and adhesion of the spraying process. Currently, the industry primarily uses traditional fixed spraying equipment for gas generator set casings. The spray nozzles in these devices are fixedly installed, and their spraying position and spacing cannot be adaptively adjusted according to the casing structure.

[0004] In actual spraying processes, due to the irregular structure of the multi-segment truncated cone of the gas generator set casing, the vertical distance between the nozzle and each spraying area of ​​the casing will continuously fluctuate with changes in the casing's cross-section and curvature, making it impossible to maintain a constant spraying spacing. When the distance between the nozzle and the casing is too small, problems such as localized paint accumulation, sagging, and excessively thick paint films are very likely to occur. When the distance between the nozzle and the casing is too large, it will cause severe paint atomization and diffusion, insufficient spray coverage, and a thinner paint film thickness, resulting in incomplete spraying in some areas of the casing, leading to defects such as missed spraying, incomplete spraying, and uneven paint film, which cannot meet the corrosion protection process standards for the unit casing.

[0005] Meanwhile, the dynamic changes in the spraying spacing can also lead to unstable paint atomization, prominent issues such as color difference and paint film thickness deviation, requiring a lot of manual labor for sanding and touch-up spraying corrections, which greatly increases processing time and production costs, and reduces overall production efficiency. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a gas generator set casing spraying device to solve the problems of existing fixed spraying devices being unable to adapt to the multi-segment truncated cone-shaped structure of gas generator set casings, dynamic fluctuations in spraying spacing, and easy occurrence of paint accumulation, sagging, missed spraying, uneven paint film thickness, and unstable atomization effect.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A gas generator set casing spraying device includes a workbench with a tray on the workbench and a clamping mechanism for clamping the gas generator set casing on the upper part of the tray. A spraying mechanism is located on one side of the workbench, including a lead screw and columns on both sides of the lead screw.

The drive mechanism includes a rotating shaft fixedly installed at the bottom of the tray, a drive pulley is installed on the rotating shaft, and a driven pulley is installed at the lower end of the lead screw. The drive pulley and the driven pulley are connected by a transmission belt. The drive mechanism also includes a motor base fixedly installed at the bottom of the workbench, a geared motor is installed on the motor base, and the output shaft of the geared motor is connected to the rotating shaft.

[0008] Furthermore, the clamping mechanism includes a fixed seat fixedly installed on the tray, the fixed seat is provided with a telescopic mechanism, the telescopic rod end of the telescopic mechanism is connected to a movable seat, the fixed seat and the movable seat are circumferentially connected with a plurality of scissor arms, and the outer end of each scissor arm is connected to a clamping plate for clamping the outer casing of the gas generator set; the telescopic mechanism adopts a hydraulic cylinder, a pneumatic cylinder, an electric push rod or a rigid chain.

[0009] Furthermore, the workbench is provided with an arc-shaped guide rail, and the lower part of the tray is provided with a slider. The slider is slidably mounted on the arc-shaped guide rail, and the arc-shaped guide rail provides guidance and support for the tray, ensuring the stability of the tray when it rotates.

[0010] Furthermore, the lead screw is a reciprocating lead screw.

[0011] Furthermore, a first groove is provided on one side of the workbench, and a first slide block is slidably connected in the first groove. The lower end of the lead screw is rotatably mounted on the first slide block, and the lower end of the column is fixedly mounted on the first slide block. A first adjusting lead screw is rotatably connected to one side of the first slide block. A first fixing plate is provided at the end of the first groove. The first adjusting lead screw is threadedly connected to the first fixing plate, and a handle is connected to the end of the first adjusting lead screw.

[0012] Furthermore, the lower part of the workbench is provided with a tensioning mechanism, which includes a base fixedly installed at the bottom of the workbench. The base is provided with a sliding groove, and a movable block is slidably connected in the sliding groove. A movable wheel is rotatably connected to the movable block. A tension spring is connected to one end of the sliding groove, and the other end of the tension spring is connected to the movable block. Fixed wheels are symmetrically arranged on both sides of the sliding groove. The fixed wheels are rotatably connected to the base. The transmission belt is sequentially wound around the outside of the driving pulley, the driven pulley, one fixed wheel, the movable wheel, and the other fixed wheel.

[0013] Furthermore, a second groove is provided on the side of the workbench away from the spraying mechanism, and a second slide is slidably connected in the second groove. A drying mechanism is provided on the second slide, and the drying mechanism includes an electric heater for quickly drying the paint surface. A second adjusting screw is rotatably connected to one end of the second slide, and the second adjusting screw is threadedly connected to a second fixed plate provided at the end of the second groove, for adjusting the distance between the drying mechanism and the gas generator set housing.

[0014] Furthermore, a brush is provided on one side of the support base for sweeping and cleaning the area of ​​the outer shell to be coated.

[0015] Furthermore, a mounting base is slidably connected to one side of the support base, and the nozzle is fixedly installed on the side wall of the mounting base by a clamp. A fastening bolt is threadedly connected to the upper end of the mounting base.

[0016] Furthermore, it also includes a sealing cover, which is used to seal the upper opening of the gas generator set casing. The lower part of the sealing cover is provided with a first step that matches the upper opening of the gas generator set casing, and the upper part of the sealing cover is provided with a second step, the outer diameter of the second step being smaller than the outer diameter of the first step. A switch for controlling the start and stop of the geared motor is provided on the side wall of the second step.

[0017] The beneficial effects of this invention are: (1) The present invention solves the industry pain points of traditional fixed spray nozzles being unable to adapt to irregular shell structures and large fluctuations in spray spacing by using an adaptive conformal adjustment structure composed of support wheels, guide rods and tightening springs, combined with a linkage drive structure for shell rotation and nozzle axial movement. This ensures the consistency of spraying, eliminates the need for a large amount of subsequent manual grinding and touch-up spraying correction, and improves the finished product quality and overall production efficiency of gas generator set shell spraying operations.

[0018] (2) The telescopic mechanism is used in conjunction with the scissor frame to form a linkage clamping structure, which has the advantages of stepless adjustment and multi-directional synchronous clamping. It can adapt to the clamping and fixing requirements of different specifications and sizes of gas generator sets with irregular shells, thus improving the versatility and adaptability of the equipment.

[0019] (3) A first groove is provided on one side of the workbench, and a sliding first slide is provided in the first groove. The spraying mechanism is installed on the first slide, which realizes the adjustment of the distance between the spraying mechanism and the gas generator set shell, and adapts to the spraying operation requirements of gas generator set shells with different outer diameter specifications.

[0020] (4) A drying mechanism is set on the other side of the workbench, and the distance between the drying mechanism and the gas generator set shell is adjustable. While the spraying mechanism sprays the gas generator set shell, the electric heater quickly dries the paint surface, avoiding dust, drips, scratches and other problems on the undried paint surface, improving the quality of the paint surface formation, shortening the overall processing cycle and improving the processing efficiency of the gas generator set shell.

[0021] (5) By setting a brush on one side of the support base, the area to be sprayed on the outer shell is swept and cleaned to remove dust, iron filings, impurities and floating dust attached to the surface of the outer shell, thus ensuring the quality of the spraying of the outer shell of the gas generator set.

[0022] (6) A sealing cap is installed at the top of the gas generator set casing to achieve a tight seal at the top of the casing, preventing paint from entering the interior of the gas generator set casing. After the equipment completes the entire spraying operation, the nozzle and support wheel move upward with the slide plate and detach from the main body of the gas generator set casing. Under the elastic force of the top spring, the support wheel tightly adheres to the second step side wall of the sealing cap and squeezes the trigger switch, thereby automatically shutting off the geared motor and terminating the linkage operation between the tray rotation and the spraying mechanism. There is no need for manual observation and control of the shutdown time, avoiding paint waste and equipment idling loss caused by overspraying and dry spraying. Attached Figure Description

[0031] The following will be combined with the appendix Figures 1-7 The technical solutions in the embodiments of the present invention are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0032] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0033] like Figures 1-3 As shown, a gas generator set casing spraying device includes a workbench 1, a tray 2 on the workbench 1, and a clamping mechanism 3 for clamping the gas generator set casing on the upper part of the tray 2; a spraying mechanism 4 is provided on one side of the workbench 1, such as... Figure 5As shown, the spraying mechanism 4 includes a lead screw 42, with columns 44 on both sides of the lead screw 42. The columns 44 and the upper ends of the lead screw 42 are connected by a connecting plate 45. A sliding plate 46 is slidably connected to the columns 44. One side of the sliding plate 46 is connected to the lead screw 42. Guide rods 49 are slidably connected to both sides of the sliding plate 46. A limiting end plate is provided at the end of the guide rod 49. A tightening spring 415 is sleeved on the outside of the guide rod 49. One end of the tightening spring 415 abuts against the sliding plate 46, and the other end abuts against the limiting end plate. A support plate 47 is fixedly connected to one end of the guide rod 49. Figure 6 As shown, a support base 48 is provided on one side of the support plate 47. A support wheel 410 is rotatably mounted on the side of the support base 48 facing the gas generator set housing. The support wheel 410 abuts against the housing. A nozzle 411 is installed on one side of the support base 48. A drive mechanism 5 is provided at the bottom of the workbench 1, such as... Figure 2 , Figure 4 As shown, the drive mechanism 5 includes a rotating shaft 52 fixedly installed at the bottom of the tray 2, a drive pulley 53 mounted on the rotating shaft 52, and a driven pulley 54 mounted at the lower end of the lead screw 42. The drive pulley 53 and the driven pulley 54 are connected by a transmission belt. The drive mechanism 5 also includes a motor base fixedly installed at the bottom of the worktable 1, a geared motor 51 mounted on the motor base, and the output shaft of the geared motor 51 is connected to the rotating shaft 52.

[0034] During the spraying operation, the gas generator set casing to be processed is first placed on the tray 2 of the workbench 1. The casing is positioned and clamped by the clamping mechanism 3 to ensure its stability during the spraying process. Then, the geared motor 51 is started, which drives the rotating shaft 52 to rotate the gas generator set casing on the tray 2, so that the casing can be evenly sprayed in all circumferential areas. At the same time, the rotating shaft 52 drives the drive pulley 53 to rotate synchronously, which drives the driven pulley 54 and the lead screw 42 to rotate synchronously through the transmission belt. The lead screw 42 drives the slide plate 46 to move back and forth vertically along the column 44. This drives the nozzle 411 to complete the entire spraying operation along the axial direction of the outer shell. During the entire process of the vertical movement of the slide plate 46 and the axial displacement of the nozzle 411 following the outer shell, the tensioning spring 415 sleeved on the guide rod 49 continuously provides tensioning force, pushing the guide rod 49 and the support seat 48 forward, so that the support wheel 410 always fits tightly against the multi-segment truncated irregular outer wall of the gas generator set outer shell. Relying on the irregular contour of the outer shell, the extension and retraction of the guide rod 49 are adaptively adjusted to compensate for the spacing deviation caused by the gradual change of the outer shell cross-sectional size and radial curvature, so that the nozzle 411 and the spraying surface of the outer shell always maintain a constant standard spraying distance.

[0035] like Figure 3As shown, the clamping mechanism 3 includes a fixed base 31 fixedly mounted on the tray 2. The fixed base 31 is equipped with a telescopic mechanism 35. A movable base 32 is connected to the end of the telescopic rod of the telescopic mechanism 35. Several scissor lifts 34 are circumferentially connected to the fixed base 31 and the movable base 32. Each scissor lift 34 has a clamping plate 33 connected to its outer end for clamping the gas generator set casing. The telescopic rod of the telescopic mechanism 35 drives the movable base 32 to move axially relative to the fixed base 31. During this movement, the circumferentially arranged scissor lifts 34 simultaneously open or retract, thereby synchronously adjusting the radial spacing of the clamping plates 33. This allows each clamping plate 33 to conform to the inner wall of gas generator set casings of different outer diameters and specifications, achieving clamping and positioning of various irregularly shaped casings. In this embodiment, the telescopic mechanism 35 uses a hydraulic cylinder; in other embodiments, the telescopic mechanism 35 may also use a pneumatic cylinder, an electric push rod, or a rigid chain.

[0036] like Figure 3 As shown, the workbench 1 is provided with an arc guide rail 12, and the lower part of the tray 2 is provided with a slider 21. The slider 21 is slidably installed on the arc guide rail 12. The arc guide rail 12 provides guidance and support for the tray 2, ensuring the stability of the tray 2 when it rotates.

[0037] When the tray 2 rotates, the slider 21 at the bottom of the tray 2 follows the rotation trajectory of the tray 2 and slides synchronously along the arc guide rail 12 of the workbench 1. The sliding cooperation between the arc guide rail 12 and the slider 21 forms a circumferential limit and a close-fitting guide support for the entire tray 2, which avoids eccentricity, shaking and tilting during the rotation of the tray 2, and ensures the stability of the equipment operation and the qualification rate of the sprayed products.

[0038] like Figure 5 As shown, the lead screw 42 is a reciprocating lead screw. When the reduction motor 51 rotates continuously in one direction, the reciprocating lead screw can automatically drive the slide plate 46 to complete the reciprocating motion of forward feeding and reverse reset along the axis of the lead screw 42 by relying on its own structural characteristics. The automatic reciprocating spraying and reset action of the spraying mechanism 4 can be realized without controlling the start and stop of the reduction motor 51 or the forward and reverse reversal.

[0039] like Figure 2 As shown, a first groove 11 is provided on one side of the workbench 1, and a first slide block 41 is slidably connected in the first groove 11. The lower end of the lead screw 42 is rotatably mounted on the first slide block 41. Figure 5As shown, the lower end of the column 44 is fixedly installed on the first slide block 41. A first adjusting screw 43 is rotatably connected to one side of the first slide block 41. A first fixing plate 13 is provided at the end of the first groove 11. The first adjusting screw 43 is threadedly connected to the first fixing plate 13. A handle is connected to the end of the first adjusting screw 43. Rotating the handle can drive the first adjusting screw 43 to rotate relative to the first fixing plate 13, causing the first slide block 41 to slide laterally in a straight line along the inside of the first groove 11, which in turn drives the spraying mechanism 4 to move synchronously, thereby adjusting the initial lateral distance between the spray nozzle 411 and the gas generator set casing. This can adapt to the spraying operation requirements of gas generator set casings with different outer diameter specifications.

[0040] like Figure 4 As shown, the lower part of the workbench 1 is provided with a tensioning mechanism 6. The tensioning mechanism 6 includes a base 61 fixedly installed at the bottom of the workbench 1. The base 61 is provided with a slide groove 62. A movable block 63 is slidably connected in the slide groove 62. A movable wheel 64 is rotatably connected to the movable block 63. A tension spring 65 is connected to one end of the slide groove 62, and the other end of the tension spring 65 is connected to the movable block 63. Fixed wheels 66 are symmetrically arranged on both sides of the slide groove 62. The fixed wheels 66 are rotatably connected to the base 61. The transmission belt is sequentially wound around the drive belt. When the spraying mechanism 4 adjusts its overall lateral position, causing the lead screw 42 to shift, the winding spacing of the transmission belt will change accordingly. At this time, the tension spring 65 continuously applies elastic thrust to the movable block 63, pushing the movable block 63 to slide adaptively along the slide groove 62, causing the movable wheel 64 to cooperate with the fixed wheels 66 on both sides to provide elastic support compensation for the transmission belt, thereby offsetting the slack generated by the transmission belt in real time, so that the transmission belt always maintains a tight and close transmission state.

[0041] like Figure 2 As shown, a second groove is provided on the side of the workbench 1 away from the spraying mechanism 4. A second slide block 71 is slidably connected in the second groove, and a drying mechanism 7 is provided on the second slide block 71. The drying mechanism 7 includes an electric heater 72. While the spraying mechanism 4 sprays the gas generator set casing, the electric heater 72 quickly dries the paint surface, avoiding problems such as dust contamination, runs, and scratches on the undried paint surface, thus improving the quality of the paint surface formation and shortening the overall processing cycle, thereby increasing the processing efficiency of the gas generator set casing. A second adjusting screw is rotatably connected to one end of the second slide block 71. The second adjusting screw is threadedly connected to a second fixed plate located at the end of the second groove, and is used to adjust the distance between the drying mechanism 7 and the gas generator set casing.

[0042] like Figure 6As shown, a brush 414 is provided on one side of the support base 48. The brush 414 sweeps and cleans the area of ​​the outer shell to be sprayed, removing dust, iron filings, impurities and floating dust attached to the surface of the outer shell, thus ensuring the quality of the spraying of the gas generator set outer shell.

[0043] like Figure 6 As shown, a mounting base 412 is slidably connected to one side of the support base 48. The spray nozzle 411 is fixedly mounted on the side wall of the mounting base 412 by a clamp 413. A fastening bolt is threadedly connected to the upper end of the mounting base 412. The mounting base 412 can slide relative to the support base 48 by sliding, thereby fine-tuning the spraying distance between the spray nozzle 411 and the gas generator set casing. After the spray nozzle 411 is adjusted to a suitable distance, the fastening bolt at the upper end of the mounting base 412 is tightened to lock the mounting base 412, thus meeting the process requirements for spraying the gas generator set casing.

[0044] like Figure 1 As shown, a sealing cap 8 is provided at the top opening of the gas generator set casing to seal the top opening of the gas generator set casing and prevent paint from being sprayed into the interior of the gas generator set casing. Figure 7 As shown, the lower part of the sealing cover 8 is provided with a first step 81 that is adapted to the upper opening of the gas generator set housing, and the upper part of the sealing cover 8 is provided with a second step 82, and the outer diameter of the second step 82 is smaller than the outer diameter of the first step 81. The side wall of the second step 82 is provided with a switch 83 for controlling the start and stop of the reduction motor 51.

[0045] Before the spraying operation, the sealing cap 8 is fitted onto the upper opening of the gas generator set casing via the matching clip of the lower first step 81, achieving a tight seal at the upper opening of the casing and preventing paint from entering the interior of the gas generator set casing. After the equipment completes the entire spraying operation, the nozzle 411 and support wheel 410 move upward with the slide plate 46 and detach from the main body of the gas generator set casing. Under the elastic force of the top spring 415, the support wheel 410 tightly adheres to the side wall of the second step 82 on the upper part of the sealing cap 8 and presses the trigger switch 83, thereby automatically shutting off the reduction motor 51 and terminating the linkage operation between the tray 2 rotation and the spraying mechanism 4. There is no need for manual observation and control of the shutdown time, avoiding paint waste and equipment idling losses caused by overspraying or dry spraying.

[0046] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the scope defined by the structure of the present invention, they should all fall within the protection scope of the present invention.
