Description

Technical Field

[0001] The utility model belongs to the technical field of automobile spare parts production, and in particular relates to a spraying jig for processing automobile air outlet shells. Background Art

[0002] Spray coating offers high production efficiency and is suitable for both manual and automated industrial production. It has a wide range of applications, primarily in hardware, plastics, furniture, military, and marine industries, making it the most commonly used coating method today. Automobile air vent housings require spray painting during production. Existing techniques typically spray products too close to people, resulting in significant air pollution. Therefore, a jig is required during spraying operations to minimize the impact of paint on human health and maintain a relatively safe production environment.

[0003] For example, patent application number CN202120794075.7 discloses a special spraying jig for automobile air outlet shells. The purpose of this utility model is a special spraying equipment designed for the structural form of the air outlet shell, which can ensure the safety and stability of the spraying work. It includes a base, a spray seat is placed in the center of the top of the base, mounting plates are fixedly connected on both sides of the base, absorption hoods are fixedly installed on the top of the two mounting plates, a fixing plate is fixedly connected to the bottom of the base, a vacuum cleaner is fixedly installed on one side of the top of the fixing plate, and a purification box is fixedly installed on the other side of the top of the fixing plate. This utility model reduces pollution to the environment, while protecting the health of relevant staff, improving the stability of the device, and facilitating the spraying work.

[0004] In the existing technology, a purification structure is set up to purify and absorb the toxic gases in the spraying process, reducing the harm to the human body. However, the fixture itself still has certain shortcomings during use: First, the existing fixture is mostly connected to the air outlet shell using a hook. During the spraying process, the shell is prone to large-scale shaking due to the high-pressure gas generated by the spray gun, making it impossible to effectively apply the paint to the shell surface, resulting in low coating efficiency and high production costs. Secondly, the shell mostly uses powder coating, and the existing purification box is prone to powder filling during the gas flow process, which can easily cause blockage and affect the purification efficiency. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a spraying jig for processing automobile air outlet shells. The utility model makes it easy to hoist the air inlet shell by means of the settings of the pressing block, the hanging hole, the connecting plate and the inclined plate. During the spraying process, the overall stability of the shell can be effectively guaranteed, so that the paint powder can be effectively adhered. The settings of the inclined nozzle and the second filter plate in the purification component can effectively prevent powder dirt from entering the interior of the bellows, avoid the occurrence of powder blockage, and improve the purification efficiency.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a spraying jig for processing automobile air outlet shells, comprising a cabinet body and a cabinet door, wherein a cabinet door is rotatably provided on one end face of the cabinet body, a rectangular opening is provided on the end face of the cabinet door, a rotating plate is rotatably provided on one side of the rectangular opening at the top of the cabinet body, two hanging hole seats are symmetrically provided on the bottom end face of the rotating plate, a downwardly inclined hanging hole in the shape of an inverted trapezoid is provided on the end face of the hanging hole seat, a connecting plate is slidably provided on one side of the hanging hole seat, two outwardly inclined inclined plates are provided on the bottom end face of the connecting plate, a flexible rod is provided on the outer end face of each inclined plate, and a purification component is provided on the end face of the cabinet body away from the cabinet door. The connection plate and the inclined plate are provided so that the air outlet shell can be pressed and fixed after hoisting, thereby improving the stability during spraying.

[0007] Preferably, a second push cylinder is provided above the connecting plate on the end surface of the rotating plate. The output end of the second push cylinder is connected to a vibrator, and the output end of the vibrator is connected to the end surface of the connecting plate.

[0008] Preferably, a plurality of anti-skid ridges are provided on the inclined wall of the hanging hole, and a plurality of anti-skid grooves are provided at the bottom of the hanging hole. The provision of the anti-skid grooves and the anti-skid ridges both improves the stability of the hook during hoisting.

[0009] Preferably, a pressure block is slidably arranged in the hanging hole, a rough surface block is arranged on the bottom end surface of the pressure block, and a flexible pad is arranged on the outside of the rough surface block on the end surface of the pressure block. The arrangement of the rough surface block and the flexible pad can prevent the hook from slipping and deflecting.

[0010] Preferably, a plurality of elastic ropes are provided between the two inclined plates, thereby improving the elastic support effect of the inclined plates.

[0011] Preferably, the purification assembly includes a bellows mounted on one end face of the cabinet, the bellows housing a removable adsorption block, and a plurality of downwardly slanted nozzles at one end of the bellows within the cabinet, each of which houses a second filter plate.

[0012] Preferably, the purification assembly further comprises a sliding opening provided on the top end surface of the bellows, one end of the top of the adsorption block extending out of the sliding opening, and a cover plate connected to the end of the adsorption block extending out of the sliding opening. The provision of the sliding opening and the cover plate allows the adsorption block to be quickly replaced after prolonged use.

[0013] Preferably, a first filter plate is provided at the bottom of the cabinet, and a recovery bin is provided in the cabinet below the first filter plate. The arrangement of the first filter plate and the recovery bin enables the fallen paint powder to be recovered and processed.

[0014] Preferably, a drive motor is provided on the end face of the cabinet, the output end of which extends into the cabinet and is connected to a rotating plate. A plurality of first push cylinders are provided on the end face of the rotating plate, the output ends of which are connected to a pressure block.

[0029] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Example 1:

[0030] refer to Figure 1-9 A spray jig for processing automobile air outlet shells includes a cabinet body 32 and a cabinet door 34. The cabinet door 34 is rotatably provided on one end surface of the cabinet body 32, and a rectangular opening 36 is provided on the end surface of the cabinet door 34. A rotating plate 39 is rotatably provided on one side of the rectangular opening 36 at the top of the cabinet body 32. Two hanging hole seats 49 are symmetrically provided on the bottom end surface of the rotating plate 39. A hanging hole 60 with a downward tilted inverted trapezoidal shape is provided on the end surface of the hanging hole seat 49. A connecting plate 45 is slidably provided on one side of the hanging hole seat 49. Two outward-tilted inclined plates 46 are provided on the bottom end surface of the connecting plate 45. A flexible rod 48 is provided on the outer end surface of each inclined plate 46. A purification component is provided on the end surface of the cabinet body 32 away from the cabinet door 34.

[0031] Specifically, one end of the cabinet door 34 is rotatably connected to the end face of the cabinet body 32 through a hinge structure. The specific hinge structure is a prior art and will not be elaborated in this article. When the air outlet shell needs to be sprayed, the staff can open the cabinet door 34. After that, the hook in the prior art can be used to hang one end of the shell, and then the other end of the hook is hooked on the hanging hole 60 inside the hanging hole seat 49. The hanging hole 60 is tilted downward as a whole and is set in an inverted trapezoidal shape. The hook can be centered so that the hook can be stably hung inside the hanging hole 60, thereby ensuring the basic stability of the shell.

[0032] When the shell is hung in the hanging hole seat 49, the connecting plate 45 will move downward, thereby driving the two inclined plates 46 and the flexible rod 48 on the end surface of the bottom to move downward. The two inclined plates 46 tilt outward and open, forming an eight-shaped arrangement. The inclined plates 46 are made of elastic metal material and form an elastic connection with the connecting plate 45, while the flexible rod 48 is made of elastic rubber material. During the downward movement, the outer circular surface of the flexible rod 48 will contact the top end surface of the shell. During the contact process, the flexible rod 48 will undergo a certain elastic deformation due to the pressure, so that the flexible rod 48 can effectively contact the special-shaped surface outside the shell, ensuring the anti-slip effect.

[0033] During the continuous pressure process, the inclined plate 46 will produce a certain elastic deformation, so that the pressure can be effectively applied to the shell. At this time, the shell originally hoisted on the hanging hole seat 49, which has a certain degree of shaking in this article, will be pushed downward by the connecting plate 45. The hook, the hanging hole seat 49 and the shell will be tightened, so that the shell can be reinforced, so that the spraying process will not cause excessive shaking due to the spraying air pressure, thereby ensuring the adhesion quality of the paint and improving the spraying quality.

[0034] After the shell is hoisted and fixed, the staff closes the cabinet door 34, and then extends one end of the spray gun through the rectangular opening 36 into the interior of the cabinet 32, and then the shell can be sprayed. At this time, the rotating plate 39 can drive the connecting plate 45 and the hanging hole seat 49 to rotate, thereby driving the hoisted shell to rotate, so that all parts of the shell can be effectively sprayed. In this relationship, the overall length of the rectangular opening 36 is slightly shorter than the height of the cabinet door 34, and the overall length of the rectangular opening 36 is higher than the overall length of the air outlet shell. The specific stroke is arranged according to actual conditions and is not restricted in this article. This setting allows the staff to slide freely in the rectangular opening 36, so that the shell can be sprayed in all aspects.

[0035] During the spraying process, the purification component will purify the toxic gas inside the cabinet 32 to reduce the adverse effects of the toxic gas inside the cabinet 32 on the workers.

[0036] refer to Figure 6A second push cylinder 43 is provided on the end surface of the rotating plate 39 above the connecting plate 45. The output end of the second push cylinder 43 is connected to a vibrator 44. The output end of the vibrator 44 is connected to the end surface of the connecting plate 45.

[0037] Specifically, the second push cylinder 43 is an existing technology, including various types such as air push cylinders, electric push cylinders, and hydraulic push cylinders, which will not be elaborated in detail here. The output end of the second push cylinder 43 can push the vibrator 44 to move downward, thereby pushing the connecting plate 45 to move downward, so that the shell can be pressed and fixed; the vibrator 44 is an existing technology, including a linear motor that can generate vibration when powered. The specific structure and model will not be elaborated in detail. After the connecting plate 45 is pressed on the top of the shell, during the spraying process, the vibrator 44 can move and vibrate the connecting plate 45 through the output end, and the connecting plate 45 will transmit the vibration to the shell through the inclined plate 46 and the flexible rod 48, so that the shell can be vibrated to a certain extent. The purpose of this setting is to shake off the excess paint powder adhering to the shell, avoid paint adhesion, and ensure the quality of spraying. This function is turned on according to actual needs. In the static state, it is equivalent to pushing the connecting rod, which does not affect the pressing of the connecting plate 45.

[0038] refer to Figure 7 A plurality of anti-slip ridges 50 are provided on the inclined wall of the hanging hole 60 , and a plurality of anti-slip grooves 51 are provided at the bottom of the hanging hole 60 .

[0039] Specifically, the provision of the anti-slip ridges 50 and the anti-slip grooves 51 can both increase the contact friction between the hanging hole 60 and the hook, so that the hook will not shake randomly during the hoisting process, thereby improving the connection effect.

[0040] refer to Figure 5-7 A pressing block 52 is slidably provided in the hanging hole 60 , a rough surface block 54 is provided on the bottom end surface of the pressing block 52 , and a flexible pad 53 is provided on the end surface of the pressing block 52 outside the rough surface block 54 .

[0041] Specifically, when the hook is hooked in the hanging hole 60, the hook will shake. At this time, the pressure block 52 will press downward, thereby driving the rough surface block 54 and the flexible pad 53 on the end surface to move downward. The rough surface block 54 is set at the center of the bottom end surface of the pressure block 52, and the outer surface is provided with multiple rough surface patterns. The flexible pad 53 is made of elastic anti-slip material and has a certain elastic deformation effect. During the downward pressing process, the rough surface block 54 will press on the top of the hook, thereby performing a hard clamping treatment on the hook, and the flexible pad 53 will produce a certain deformation according to the shape change of the top of the hook, thereby forming an elastic support treatment on the outside of the rough surface block 54, thereby effectively improving the anti-slip effect of the hook, so that the hook will not shake at will.

[0042] refer to Figure 4A driving motor 33 is provided on the end face of the cabinet 32, and the output end of the driving motor 33 extends into the cabinet 32 and is connected to the rotating plate 39. A plurality of first pushing cylinders 42 are provided on the end face of the rotating plate 39, and the output end of the first pushing cylinder 42 is connected to the pressure block 52.

[0043] Specifically, the drive motor 33 and the first push cylinder 42 are both existing technologies. The specific selection and parameters will not be elaborated in this article. The output end of the drive motor 33 can drive the rotating plate 39 to rotate, thereby driving the shell hoisted under the rotating plate 39 to rotate, thereby increasing the spray coverage area, and the output end of the first push cylinder 42 can push the pressure block 52 to move up and down, so that the hook can be smoothly clamped and fixed.

[0044] refer to Figure 9 The purification component includes a bellows 38 arranged on one end face of the cabinet 32, and a detachable adsorption block 56 is arranged in the bellows 38. The bellows 38 is located in the cabinet 32 and has a plurality of downwardly inclined inclined pipe openings 58 at one end, and each inclined pipe opening 58 is provided with a second filter plate 59.

[0045] Specifically, the outside of the bellows 38 can be connected to an air pump, and the air pump model is of existing technology, which will not be elaborated in this article. When the air pump is turned on, high-pressure gas flow can be generated, so that the bellows 38 can draw the toxic gas inside the cabinet 32 into the bellows 38 through the inclined pipe mouth 58. The second filter plate 59 will intercept and filter the powder flowing to the inclined pipe mouth 58 during this process to avoid clogging inside the adsorption block 56. The adsorption block 56 that is detachably arranged inside the bellows 38 is of existing technology, which will not be elaborated in this article. The adsorption block 56 can filter and adsorb the toxic gas so that the gas discharged from the other end of the air pump meets the standard, thereby ensuring a good processing environment. In this relationship, the bellows 38 and the multiple inclined pipe mouths 58 are basically flush with the height of the rotating plate 39 and the bellows 38 is tilted downward. On the one hand, compared with the traditional straight cylinder, it can reduce the powder entering the bellows 38 and avoid clogging of the bellows 38. On the other hand, the position is relatively high, and the upward flow effect of the gas is better, thereby improving the purification efficiency.

[0046] refer to Figure 9 The purification component also includes a sliding opening 57 provided on the top end surface of the bellows 38 , one end of the top of the adsorption block 56 extends out of the sliding opening 57 , and one end of the adsorption block 56 extending out of the sliding opening 57 is connected to a cover plate 55 .

[0047] Specifically, the bottom end face of the cover plate 55 covers the end face outside the sliding opening 57, thereby sealing the sliding opening 57. When the adsorption block 56 needs to be replaced, the cover plate 55 is pulled to pull the adsorption block 56 outward, so that the adsorption block 56 can be quickly replaced after long-term use.

[0048] refer to Figure 1 Handles 37 are provided on both sides of the top end surface of the cabinet body 32, and a plurality of glass windows 35 are provided on the end surface of the cabinet door 34 below the handles 37.

[0049] Specifically, the provision of the handle 37 allows the cabinet 32 as a whole to be easily taken, and the provision of the glass window 35 allows the staff to understand the spraying status inside the cabinet 32, making it easier to make judgments and changes, thereby improving the spraying quality. Example 2:

[0050] On the basis of or different from the first embodiment, reference is made to Figure 6 A plurality of elastic ropes 47 are connected between the two inclined plates 46 .

[0051] Specifically, multiple elastic ropes 47 are made of elastic material and are arranged between the two inclined plates 46. They can elastically reinforce the two inclined plates 46, avoid excessive bending and floating of the inclined plates 46, and prevent insufficient pressing support effect, thereby improving the fixing effect. Example 3:

[0052] On the basis of or different from the first embodiment, reference is made to Figure 8 A first filter plate 40 is provided at the bottom of the cabinet 32 , and a recovery bin 41 is provided below the first filter plate 40 in the cabinet 32 .

[0053] Specifically, a port is provided at one end of the outside of the recovery bin 41, and the staff can connect the suction pump to the outside of the recovery bin 41. In this relationship, the suction pump is a prior art and will not be elaborated in this article. The suction pump can extract the paint powder, and a certain amount of gas flow will be generated during the extraction process. When the cabinet 32 is sprayed inside, a certain amount of gas flow will be generated inside the recovery bin 41 due to the suction pump, so that the powder paint that is not adhered to the air outlet shell will flow downward. At this time, the first filter plate 40 can filter the adhered powder and debris, and the filtered powder will enter the recovery bin 41 to complete the recycling process.

[0054] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0055] It should be noted that the terms "include," "comprises," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a product or system comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such product or system. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of other identical elements in the product or system comprising the element.

[0056] The above description shows and describes several preferred embodiments of the present application. However, as previously mentioned, it should be understood that the present application is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present application can be used in various other combinations, modifications, and environments and can be modified within the scope of the application concept described herein through the above teachings or technology or knowledge in the relevant field. Modifications and changes made by those skilled in the art that do not depart from the spirit and scope of the present application should be protected by the claims appended hereto.
