Description

Technical Field

[0001] This utility model relates to the field of positioning technology for wheel hub painting, and more specifically, to a wheel hub painting positioning mechanism. Background Technology

[0002] Currently, after wheel rims are manufactured, they undergo electrostatic spraying, which gives them a completely new appearance, such as metallic sheen, matte finish, or smooth texture, meeting the personalized needs of car owners and making the vehicle's appearance more unique and stylish.

[0003] Furthermore, electrostatic powder coating enhances the durability of wheel rims. The high hardness and wear resistance of the electrostatic powder coating effectively protect the wheel rim surface, preventing scratches and abrasions and extending the wheel rim's lifespan. Simultaneously, the coating also provides corrosion resistance and protection against external erosion, further improving the wheel rim's durability.

[0004] The existing wheel hub painting process is as follows:

[0005] (1) Place the wheel hub stably on the spray painting table;

[0006] (2) Use a handheld electrostatic spray gun to spray the surface of the wheel hub;

[0007] (3) During the spraying process, the operator moves around to change the position or manually rotates the wheel hub to improve the spraying effect;

[0008] The above process, which involves manually changing the orientation of the sprayed wheel hub, is labor-intensive and prone to oversights. Manually rotating the wheel hub is also inconvenient. Therefore, the ease of operation in the wheel hub spraying process needs to be further improved. Utility Model Content

[0009] The purpose of this invention is to solve the problems mentioned in the background art and to propose a wheel hub spraying positioning mechanism.

[0010] The technical solution adopted by this utility model to solve its technical problem is:

[0011] A wheel hub spraying positioning mechanism includes an alloy shell, a rotating roller, a through hole, a gear transmission assembly, a placement disk, an intermediate roller, and side rollers.

[0012] The rotating roller is rotatably connected to an alloy shell fixed to the ground, and the alloy shell has a through hole that allows the rotating roller to pass through.

[0013] The gear transmission assembly is fixed inside the alloy shell and connected to the rotating roller;

[0014] The placement tray is welded to one end of the rotating roller;

[0015] The intermediate roller and five side rollers are all welded to the placement plate, and the side rollers are distributed around the circumference of the intermediate roller. The size of the intermediate roller is matched with the size of the center hole of the hub, and the size of the side rollers is matched with the size of the bolt holes of the hub and corresponds one-to-one.

[0016] Furthermore, rubber sleeves are fitted on the outer sides of both the intermediate roller and the side rollers.

[0017] The above solution uses rubber sleeves to avoid the probability of hard contact and wear between the intermediate roller and the side roller and the center hole and bolt hole of the hub, respectively, thus making the placement and positioning of the hub better and faster.

[0018] Furthermore, the rotating roller is provided with an installation groove, and a telescopic component is provided in the installation groove. The telescopic component is connected to a placement plate.

[0019] After the outer side of the wheel hub is painted, the above solution allows the telescopic component to move via a controller, raising the wheel hub to a pre-set height. This facilitates electrostatic spraying of the wheel hub's interior, resulting in a better painting effect.

[0020] Furthermore, two rotating rollers are rotatably connected inside the alloy shell, and the alloy shell has through holes corresponding to the rotating rollers. One of the rotating rollers is fixed with a main pulley, and the other rotating roller is fixed with a secondary pulley. The main pulley and the secondary pulley are connected by a tensioned belt.

[0021] When the gear transmission assembly operates, the above scheme can synchronously drive two rotating rollers to rotate two hubs, thereby increasing the number of hubs to be painted.

[0022] Furthermore, the alloy shell is provided with a movable cover and a heat-insulating shell spaced apart from the wheel hub, and a temperature-controlled heater is fixed inside the heat-insulating shell.

[0023] Furthermore, the heat-insulating outer shell is symmetrically fixed with fixing blocks, and the alloy shell is fixed with mounting blocks that correspond one-to-one with the fixing blocks. The mounting blocks are fixed with insert rollers, and the fixing blocks are provided with insertion holes that correspond one-to-one with the insert rollers and are of suitable size.

[0024] After the electrostatic spraying of the wheel hub is completed, the above solution is used to cover the alloy shell with the insulation shell and start the temperature control heater. This will raise the temperature of the area enclosed by the insulation shell and the alloy shell to preheat the wheel hub. Preheating allows the paint on the wheel hub to reach a certain temperature before entering the oven, which helps the paint to reach the temperature required for curing in the oven more quickly, thereby accelerating the curing process. After preheating is completed, the insulation shell can be removed. The installation and removal of the insulation shell is convenient.

[0025] Furthermore, a tray is placed on the alloy shell.

[0026] The above method allows the preheated wheel hub to be removed from the placement tray and immediately placed on a pallet. The pallet can then be transferred to an oven for the heating and curing process.

[0027] Compared with the prior art, the beneficial effects of this utility model are:

[0028] Compared to existing technologies, this device can achieve fast and convenient positioning of the wheel hub with a firm positioning effect. After positioning, the wheel hub can be rotated slowly and uniformly. Then, the surface of the wheel hub can be sprayed by simply holding the electrostatic spray gun and changing the position and tilt angle of the gun head on one side of the wheel hub. The spraying process is optimized and the labor intensity is reduced. There is no need to contact the wheel hub or change positions, resulting in a better spraying and positioning effect.

Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0037] like Figure 1As shown, a wheel hub spraying positioning mechanism includes an alloy shell 1, a rotating roller 2, a through hole 3, a gear transmission assembly 4, a placement disk 5, an intermediate roller 6, and a side roller 7.

[0038] The rotating roller 2 is rotatably connected to the alloy shell 1 fixed on the ground, and the alloy shell 1 has a through hole 3 that allows the rotating roller 2 to pass through.

[0039] The gear transmission assembly 4 is fixed inside the alloy shell 1 and connected to the rotating roller 2;

[0040] The placement tray 5 is welded to one end of the rotating roller 2;

[0041] The intermediate roller 6 and five side rollers 7 are all welded to the placement plate 5 and the side rollers 7 are distributed around the circumference of the intermediate roller 6. The intermediate roller 6 is adapted to the size of the center hole of the wheel hub, and the side rollers 7 are adapted to the size of the bolt holes of the wheel hub and correspond one-to-one.

[0042] Further optimizations of the above-described embodiments, such as... Figure 2 As shown, rubber sleeves 8 are fitted on the outer sides of both the intermediate roller 6 and the side roller 7.

[0043] It should be noted that the gear transmission assembly 4 is electrically connected to the controller, which is not labeled in the figure.

[0044] The working process of this utility model is as follows:

[0045] First, place the wheel hub from top to bottom close to the placement plate 5 (during placement, the side of the wheel hub with the center hole and bolt holes facing upwards) and make slight adjustments to the position so that the middle roller 6 passes through the center hole of the wheel hub, and the five side rollers 7 pass through the five bolt holes of the wheel hub respectively. After placement, the wheel hub contacts the placement plate 5, and then the gear transmission assembly 4 can be started. The speed of the servo motor in the gear transmission assembly 4 is preset so that the wheel hub will rotate slowly and uniformly with the rotating roller 2. At this time, the operator only needs to hold the electrostatic spray gun and change the position and tilt angle of the electrostatic spray gun head in a fixed area on one side of the wheel hub to achieve effective spraying on the surface of the wheel hub.

[0046] On this basis, the rubber sleeve 8 can avoid the probability of hard contact and wear between the middle roller 6 and the side roller 7 and the center hole and bolt hole of the wheel hub, respectively, thus making the wheel hub placement and positioning effect better and faster.

[0047] Compared to existing technologies, this device can achieve fast and convenient positioning of the wheel hub with a firm positioning effect. After positioning, the wheel hub can be rotated slowly and uniformly. Then, the surface of the wheel hub can be sprayed by simply holding the electrostatic spray gun and changing the position and tilt angle of the gun head on one side of the wheel hub. The spraying process is optimized and the labor intensity is reduced. There is no need to contact the wheel hub or change positions, resulting in a better spraying and positioning effect.

[0048] In some embodiments, such as Figure 3 As shown, the rotating roller 2 has an installation groove 9, and a telescopic component 10 electrically connected to the controller is provided in the installation groove 9. The telescopic component 10 is connected to the placement plate 5. In this embodiment, after the outer side of the wheel hub is sprayed, the telescopic component 10 can be controlled by the controller to move, which will then raise the wheel hub to a preset height, making it easier to perform electrostatic spraying on the inside of the wheel hub, resulting in a better spraying effect. It should be noted that before the wheel hub is raised, the electrostatic spray gun can only be inserted into the inside of the wheel hub from below for spraying. At this time, the spraying personnel are higher than the wheel hub, making it inconvenient to operate and observe the spraying effect.

[0049] In other embodiments, such as Figure 4 As shown, two rotating rollers 2 are rotatably connected inside the alloy shell 1, and the alloy shell 1 has through holes 3 that correspond one-to-one with the rotating rollers 2 and allow the rotating rollers 2 to pass through. One rotating roller 2 is fixed with a main pulley 11, and the other rotating roller 2 is fixed with a secondary pulley 12. The main pulley 11 and the secondary pulley 12 are connected by a tensioned belt 13. In this embodiment, when the gear transmission assembly 4 is in operation, it can synchronously drive the two rotating rollers 2 to drive the two hubs to rotate, thereby increasing the number of hubs to be sprayed.

[0050] In other embodiments, such as Figure 5 As shown, the alloy shell 1 has a movable cover with heat-insulating shells 14 spaced apart from the wheel hub, and a temperature control heater 15 is fixed inside the heat-insulating shell 14.

[0051] In a further optimization of the above embodiment, a fixing block 18 is symmetrically fixed on the heat insulation shell 14, and an mounting block 16 corresponding to the fixing block 18 is fixed on the alloy shell 1. An insertion roller 17 is fixed on the mounting block 16, and an insertion hole (not shown in the figure) corresponding to the insertion roller 17 is opened on the fixing block 18. After the electrostatic spraying of the wheel hub is completed, the heat insulation shell 14 is immediately placed on the alloy shell 1 and the temperature control heater 15 is started, which can raise the temperature of the area enclosed by the heat insulation shell 14 and the alloy shell 1 to preheat the wheel hub. Preheating can make the paint on the wheel hub reach a certain temperature before entering the oven, which helps the paint to reach the temperature required for curing faster in the oven, thereby accelerating the curing process. After preheating is completed, the heat insulation shell 14 can be removed. The installation and disassembly of the heat insulation shell 14 is convenient.

[0052] In other embodiments, a tray is placed on the alloy shell 1, which is not shown in the figure; in this embodiment, after the preheated wheel hub is removed from the placement plate 5, it can be placed on the tray immediately, and then the tray can be transferred to the oven for the heating and curing process. The heating and curing process can improve the adhesion and overall quality of the coating.

[0053] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
