Description

Technical Field

[0001] The present invention belongs to the technical field of wheel hub processing, and particularly relates to a spraying suspension device for automobile wheel hub processing. Background Art

[0002] The wheel hub is an important part of a vehicle. The design and manufacture of the wheel hub need to consider its structural strength and durability to support the weight of the vehicle and withstand various forces during driving. In addition to its structural function, the appearance of the wheel hub is also important, and wheel hub painting is an important process to improve its appearance.

[0003] When painting the wheel hub, some paint drifts away. The prior art usually sets up a collection mechanism to collect the drifted paint. However, due to the low surface temperature of the paint collection mechanism, the paint is prone to solidify when flowing in the collection mechanism. And because the paint has a certain viscosity, the flow rate of the paint adhering to the collection mechanism is relatively slow, which accelerates the solidification of the paint, resulting in the paint being unable to be recycled for secondary use, and it is not easy to clean the paint solidified on the collection mechanism. Therefore, a spraying suspension device is provided to solve this problem. Summary of the Invention

[0030] The following further describes the present application in detail with reference to the drawings. It is necessary to point out here that the following specific implementation manners are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0031] Embodiment 1

[0032] As shown Figure 1 , Figure 2 and Figure 3 shown, an automobile wheel hub processing and spraying suspension device includes a support mechanism 1, a collection mechanism 2 and a fixing mechanism 4. The collection mechanism 2 is arranged on the support mechanism 1. The collection mechanism 2 includes a material collecting box 201 and a collection box 203. The collection box 203 is connected below the material collecting box 201. The wheel hub is placed on the fixing mechanism 4 and above the material collecting box 201. The material collecting box 201 is used to guide the excess paint to flow to the collection box 203. Ventilation grooves 205 are formed on the side wall of the material collecting box 201;

[0033] A drying mechanism 3 is arranged on the support mechanism 1, which is used to dry the wheel hub and heat the side wall of the collection box 203;

[0034] A scraping assembly 7 is arranged in the material collecting box 201, which is used to scrape the paint on the inner wall of the material collecting box 201 after the wheel hub painting is completed. The scraping assembly 7 includes a scraping plate 71. A driving mechanism 8 is arranged on the scraping plate 71. The driving mechanism 8 drives the scraping plate 71 to scrape along the inner wall of the material collecting box 201, and the paint on the inner wall of the material collecting box 201 is gathered together.

[0035] Specifically, the support mechanism 1 includes a base 101, an outer cylinder wall 102 and a bracket 103. The outer cylinder wall 102 is fixedly connected to the surface of the base 101. The bracket 103 is rotatably connected inside the outer cylinder wall 102. The material collecting box 201 is fixedly connected to one end of the bracket 103 away from the outer cylinder wall 102.

[0036] It should be noted that the base 101 is used to connect external equipment, and the bracket 103 provides support.

[0037] It should be further noted that after the spraying of the wheel hub is completed, the scraping assembly 7 can scrape the residual paint on the inner wall of the material collecting box 201, so that the paint can be quickly gathered together, accelerating the speed of the paint flowing to the discharge pipe 204. Through this setting, the heating of the material collecting box 201 by the drying mechanism 3 can be ended in advance, thereby reducing the energy consumption of the entire device.

[0038] Furthermore, a material collecting groove 206 is formed by the downward depression of the upper surface of the material collecting box 201. A discharge hole 202 communicating with the material collecting groove 206 is formed on the surface of the material collecting box 201. The collection box 203 is connected to the surface of the material collecting box 201 and communicates with the discharge hole 202. A discharge pipe 204 is connected to one side surface of the collection box 203 away from the discharge hole 202, and the discharge pipe 204 communicates with the inside of the collection box 203.

[0039] Specifically, both the material collecting box 201 and the material collecting groove 206 are arranged in a ring shape.

[0040] It should be noted that during painting, the excess paint flows into the discharge hole 202 along the material collecting groove 206, and is recycled through the collecting box 203 and the discharge pipe 204. The heating wire 305 heats the air in the drying box 301, and the blower 303 drives the hot air to enter the ventilation pipe 5 through the through hole 307, circulates in the ventilation groove 205 of the material collecting box 201, and is discharged through the exhaust hole 207 to maintain the temperature on the surface of the material collecting box 201 (the maintained temperature is about 5-10 °C) to prevent the paint from solidifying. After painting, the solenoid valve 304 can be opened, and the hot air in the drying box 301 (about 50-70 °C) directly dries the hub paint layer through the exhaust pipe 306 to accelerate the volatilization of moisture.

[0041] It should be further noted that a collecting bucket can be provided at the end of the discharge pipe 204 far from the discharge hole 202 for collecting the paint flowing out from the discharge pipe 204.

[0042] Furthermore, a baffle 11 is fixedly connected to the inner wall of the material collecting box 201. Two sets of scraping plates 71 are provided and symmetrically arranged on both sides of the baffle 11. Both sets of scraping plates 71 are slidably connected to the surface of the material collecting groove 206. A sliding groove 75 is formed on the surface of the material collecting groove 206. A connecting plate 72 is slidably connected to the inner wall of the sliding groove 75. The connecting plate 72 is correspondingly arranged and fixedly connected to the scraping plate 71. Defective racks 73 are fixedly connected to the surfaces of both sets of connecting plates 72 far from the scraping plates 71. The defective racks 73 are respectively engaged with driving gears 74. A driving mechanism 8 is installed on the support mechanism 1, and the driving mechanism 8 is used to drive the two driving gears 74 to rotate.

[0043] Specifically, when the scraping plate 71 is attached to the surface of the baffle 11, it is the initial position of the scraping plate 71. During the spraying of the hub, the scraping plate 71 is always in the initial position. After the spraying is completed, in order to accelerate the flow of the paint in the material collecting groove 206, the driving mechanism 8 drives the two driving gears 74 to rotate in opposite directions, thereby driving the two scraping assemblies 7 to rotate, so as to scrape the paint on the surface of the material collecting groove 206, so that the paint quickly gathers together and then flows into the discharge hole 202.

[0044] In actual use, the driving mechanism 8 can drive the two driving gears 74 to rotate in opposite directions. The two driving gears 74 rotating in opposite directions respectively drive the two defective racks 73 to slide along the surface of the material collecting box 201, further driving the two scraping plates 71 to move starting from one end close to the baffle 11, so as to scrape the paint on the inner wall of the material collecting box 201.

[0045] This embodiment provides a structure of the driving mechanism 8. Specifically, as Figure 4As shown, the driving mechanism 8 includes a second driving member 81, a driving bevel gear 82, a transmission bevel gear 83, and a driven bevel gear 84. The driving end of the second driving member 81 is fixedly connected to the upper driving gear 74 through a rotating shaft 85. A rotating sleeve 86 is sleeved on the surface of the rotating shaft 85. One end of the rotating sleeve 86 away from the second driving member 81 is fixedly connected to the lower driving gear 74. The driving bevel gear 82 is fixedly sleeved on the surface of the rotating shaft 85, and the driven bevel gear 84 is fixedly sleeved on the surface of the rotating sleeve 86. The transmission bevel gear 83 is rotatably connected to the surface of the material collecting box 201. Both the driving bevel gear 82 and the driven bevel gear 84 are engaged with the transmission bevel gear 83.

[0046] It should be noted that the second driving member 81 is a motor, which can be a servo motor, a stepping motor, etc.

[0047] In actual use, the second driving member 81 drives the rotating shaft 85 to rotate, thereby driving the driving bevel gear 82 and the driving gear 74 (the upper driving gear 74) connected to the rotating shaft 85 to rotate. Under the cooperation of the transmission bevel gear 83 and the driven bevel gear 84, the rotating sleeve 86 and the driving gear 74 (the lower driving gear 74) connected to the rotating sleeve 86 are driven to rotate (the rotating direction is opposite to that of the rotating shaft 85).

[0048] As Figure 2 shown, the drying mechanism 3 includes a drying box 301 and a heating wire 305. The heating wire 305 is installed in the drying box 301 for heating the air in the drying box 301. An air inlet 302 is provided on one side surface of the drying box 301. A blower 303 is connected at the air inlet 302. A ventilation pipe 5 is fixedly connected to the surface of the drying box 301 away from the air inlet 302. One end of the ventilation pipe 5 away from the drying box 301 is communicated with a ventilation groove 205. Exhaust holes 207 are provided on the inner wall of the ventilation groove 205. The blower 303 blows the hot air in the drying box 301 into the ventilation groove 205 through the ventilation pipe 5 to prevent the paint from solidifying in the material collecting box 201.

[0049] Furthermore, the drying mechanism 3 further includes an exhaust pipe 306. The exhaust pipe 306 is connected to the surface of the drying box 301 and is communicated with the inside of the drying box 301. One end of the exhaust pipe 306 away from the drying box 301 is aligned with the surface of the wheel hub.

[0050] Specifically, a plurality of drying boxes 301 are provided and are distributed in a ring shape. Through holes 307 are provided on the surface of the drying box 301. The ventilation pipe 5 corresponds to the position of the through hole 307 and is communicated with the inside of the drying box 301 through the through hole 307.

[0051] It should be noted that a first valve is fixedly connected to one end of the exhaust duct 306 away from the drying box 301. In this embodiment, the first valve is an electromagnetic valve 304. In other embodiments, the first valve can be any type of electrically controlled valve; a second valve is arranged in the through hole 307, and the second valve is any type of electrically controlled valve. The second valve can cooperate with the scraping assembly 7. Specifically, when spraying the hub, the second valve needs to be always open. After the spraying of the hub is completed, the second valve can be closed.

[0052] It should be further noted that in order to prevent the paint from solidifying on the inner wall of the material collecting box 201, the drying mechanism 3 needs to continuously heat the side wall of the material collecting box 201 until all the paint flows out of the material collecting box 201. Therefore, the scraping assembly 7 is provided to enable the paint in the material collecting box 201 to quickly gather together. After the spraying of the hub is completed, the second valve can be closed. After the second valve is closed, the hot air heated by the heating wire 305 in the drying box 301 is all discharged from the exhaust duct 306, making the hot air more concentrated, which can accelerate the drying of the paint on the surface of the hub. Moreover, the scraping assembly 7 not only quickly gathers the paint in the material collecting box 201, but also plays a role in cleaning the material collecting box 201, improving the overall working efficiency.

[0053] As Figure 2 and 5 As shown, the fixing mechanism 4 includes a support 401, a first driving member and a triggering member. The support 401 is installed on the surface of the material collecting box 201. A connecting rod 409 is fixedly connected to the upper surface of the support 401. One end of the connecting rod 409 away from the support 401 is connected to a plug-in block 408. A plurality of telescopic grooves 406 are formed in the side surface of the plug-in block 408. Each group of telescopic grooves 406 is slidably connected with a support plate 405. One end of each group of support plates 405 extends to the outside of the telescopic groove 406. One end of each group of support plates 405 away from the telescopic groove 406 is rotatably connected to a support rod 407. One end of each group of support rods 407 away from the support plate 405 is rotatably connected to the surface of the triggering member.

[0054] It should be noted that multiple groups of support plates 405 are annularly distributed, and their gripping force enables the hub to rotate with the support 401. A plurality of groups of handles 6 are fixedly connected to the outer surface of the material collecting box 201. The staff can hold the handles 6 to drive the material collecting box 201 to rotate, realizing 360° spraying of the hub, which not only reduces the labor intensity of the staff, but also facilitates the staff to conduct visual inspection.

[0055] Furthermore, the triggering member is a threaded ring 404, and the first driving member includes a lead screw 403 and a hand wheel 402. A rotating groove is formed in the lower surface of the plug-in block 408. The lead screw 403 is rotatably connected in the rotating groove. One end of the lead screw 403 away from the rotating groove penetrates through the threaded ring 404 and the support 401 and is fixedly connected to the hand wheel 402. The threaded ring 404 is threadedly connected to the surface of the lead screw 403.

[0056] In this embodiment, the handwheel 402 can be replaced by a motor, and the motor can be a stepper motor, a servo motor, etc.

[0057] In actual use, manually rotating the handwheel 402 can cause the threaded ring 404 to move up and down along the surface of the connecting rod 409. The up and down movement of the threaded ring 404 in cooperation with the support rod 407 can drive the support plate 405 to slide in the telescopic groove 406. By rotating the handwheel 402, the length of the support plate 405 extending out of the telescopic groove 406 can be adjusted to adapt to different sizes of wheel hubs. The setting of the fixing mechanism 4 can ensure the stable gripping force of the support plate 405 and prevent the wheel hub from loosening.

[0058] Embodiment Two

[0059] This embodiment provides an automobile wheel hub processing and spraying suspension device. On the basis of Embodiment One, a scraping component 9 is added, which can quickly clean the paint residues on the surface of the scraping plate 71 and further facilitate the rapid outflow of the paint from the material collecting box 201. Specifically, as Figure 3 , Figure 6 , Figure 7 and Figure 8 shown, at one end of the material collecting box 201 away from the baffle 11, a mounting plate 12 is fixedly connected. The surface of the mounting plate 12 is provided with a mounting groove, and a scraping component 9 is mounted on the mounting plate 12 for scraping the paint on the surface of the scraping plate 71. The scraping component 9 is symmetrically arranged. The scraping component 9 includes a driving plate 96 and a rotating shaft 93. The driving plate 96 is slidably connected in the mounting groove. The rotating shaft 93 penetrates the driving plate 96 and is rotatably connected to the inner wall of the mounting groove. On the surfaces of the rotating shaft 93 on both sides of the driving plate 96, a first rotating cylinder 94 and a second rotating cylinder 95 are respectively sleeved. The first rotating cylinder 94 is rotatably connected to the surface of the rotating shaft 93, and the second rotating cylinder 95 is fixedly connected to the surface of the rotating shaft 93. Connecting blocks 98 are fixedly connected to the surfaces of the first rotating cylinder 94 and the second rotating cylinder 95. Limiting blocks 97 are rotatably connected to both groups of connecting blocks 98. A limiting groove 99 is formed on the surface of the driving plate 96, and the limiting blocks 97 extend into the limiting groove 99. A first scraping rod 91 is fixedly connected to one end of the rotating shaft 93 where the first rotating cylinder 94 is located, and a second scraping rod 92 is fixedly connected to the surface of the first rotating cylinder 94. A driving component 10 is connected to the surface of the driving plate 96.

[0060] It should be noted that the lower end of the mounting plate 12 does not contact the surface of the material collecting groove 206, and discharge holes 202 are also formed at the positions on the surface of the material collecting groove 206 corresponding to the mounting plate 12.

[0061] It should be further noted that when the scraping plate 71 is attached to the surfaces of the first scraping rod 91 and the second scraping rod 92, it is the end position of the scraping plate 71. When the scraping plate 71 moves to the end position, the driving component 10 drives the driving plate 96 to move, so that the first scraping rod 91 and the second scraping rod 92 rotate.

[0062] During actual use, the driving plate 96 is pushed to move along the installation groove. Through the cooperation of the limiting block 97 and the limiting groove 99, the first rotating cylinder 94 and the second rotating cylinder 95 can be driven to rotate in opposite directions, thereby driving the first scraping rod 91 and the second scraping rod 92 to rotate to scrape the paint on the surface of the scraping plate 71.

[0063] It should be noted that the first scraping rod 91 and the second scraping rod 92 are in a V shape.

[0064] Furthermore, the driving assembly 10 includes a pushing plate 1001. The pushing plate 1001 is fixedly connected to the surface of the driving plate 96 and extends to the outside of the installation groove. A partition plate 1003 is connected to the surface of the pushing plate 1001. A spring 1002 is fixedly connected to the surface of the partition plate 1003 close to the installation groove, and the other end of the spring 1002 is fixedly connected to the inner wall of the installation groove.

[0065] During actual use, pressing the pushing plate 1001 can drive the driving plate 96 to move, and the cooperation of the spring 1002 and the partition plate 1003 can reset the pushing plate 1001.

[0066] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
