Description

Technical Field

[0001] This utility model relates to the field of wheel hub processing technology, specifically a continuous wheel hub spraying equipment. Background Technology

[0002] As a core component of the vehicle's running system, the wheel hub is connected to the axle through a central mounting hole, and its outer edge supports the tire to form the running assembly.

[0003] Currently, mainstream wheel hubs are made using aluminum alloy casting or steel forging processes. To meet the requirements for corrosion resistance and aesthetic decoration, multiple layers of coating are required on their surface.

[0004] However, the current spraying process still has the following shortcomings:

[0005] 1. In actual use, operators need to manually suspend the wheel hub on the conveyor chain or rotating sling and transfer it to the spraying station by lifting equipment. This process has problems such as high labor costs and positioning accuracy depending on operating experience.

[0006] 2. During the spraying stage, workers usually use spray guns to spray the outer surface of the wheel hub and the gaps between the spokes in steps. Because the wheel hub has a multi-spoke design, the operator needs to frequently adjust the position and spray gun angle, resulting in poor spraying uniformity and serious paint waste. Utility Model Content

[0007] The purpose of this invention is to provide a continuous wheel hub spraying device to solve the problems mentioned in the prior art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a continuous wheel hub spraying device, comprising: a spraying chamber, a hoisting unit slidably suspended on the top of the spraying chamber, an extended positioning unit assembled inside the hoisting unit, and a wheel hub clamped on the positioning unit; three sets of rotating units are fixedly installed on the top of the spraying chamber, and a spraying unit is installed on the top of the rotating unit.

[0009] The spraying unit has a support frame fixedly mounted on top of the rotating unit, a guide shell fixedly mounted on top of the support frame, a spraying rod mounted on the side of the guide shell, and a nozzle mounted on the inner wall of the spraying rod. One side of the hub is located between the spraying rods. The hoisting unit includes a lower hoisting rod with a mounting cavity at its bottom and four sets of mounting ports at the bottom of the mounting cavity. The positioning unit has a clamping component mounted inside the mounting port, a friction contact fixedly connected to the outside of the clamping component, an irregular gear fixedly connected to the top of the clamping component, a hydraulic telescopic cylinder II fixedly connected to the top of the mounting cavity, and a square toothed column meshing with the irregular gear mounted at the bottom of the hydraulic telescopic cylinder II.

[0010] Preferably, the rotating unit includes a mounting base, the top of the spraying chamber is fixedly connected to the mounting base, an upper turntable is slidably rotated inside the mounting base, a drive shaft connected to the upper turntable is connected to the bottom of the mounting base, and the drive shaft is hollow inside. An electric motor is fixedly connected to the bottom of the mounting base, and the output end of the electric motor is connected to a pulley that is driven by the drive shaft.

[0011] As a preferred embodiment, a mounting base is fixedly installed on the top of the support frame, and a guide shell is fixedly installed on the top of the mounting base. A liquid guiding cavity is fixedly connected to the bottom of the mounting base. A mounting joint communicating with the drive shaft is installed on the top of the liquid guiding cavity. The mounting joint is rotatably connected to the drive shaft. A guide square tube is installed on one side of the mounting base. The guide square tube is connected to the liquid guiding cavity through a branch pipe. A guide joint communicating with the drive shaft is installed on the top of the upper turntable. A communicating metal conduit is rotatably connected to the top of the guide joint. The other end of the metal conduit is connected to the guide shell.

The lower hoisting rod is sleeved and connected to the upper hoisting rod, and the top of the lower hoisting rod is installed and connected to the output end of the hydraulic telescopic cylinder.

[0014] As a preferred option, movable shafts are installed on both sides of the clamping member, and the clamping member is movably connected to the mounting port through the movable shafts.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example: This utility model provides a technical solution for a continuous wheel hub spraying equipment, such as... Figures 1-6 As shown, it includes: a spraying chamber 100, a lifting unit 400 that is slidably suspended on the top of the spraying chamber 100, an extended positioning unit 600 that is assembled inside the lifting unit 400, and a wheel hub that is clamped on the positioning unit 600; three sets of rotating units 200 that are fixedly installed on the top of the spraying chamber 100, and a spraying unit 300 that is docked to the top of the rotating unit 200.

[0033] In the above scheme:

[0034] The spray booth 100 enables the built-in installation of the working components, ensuring that the working components can be sprayed inside the spray booth 100.

[0035] Through the cooperation between the hoisting unit 400 and the positioning unit 600, the wheel hub is positioned by the built-in clamping method. The insertion docking positioning is faster and more convenient than the traditional hanging and picking method, and also ensures the stability of the wheel hub during transportation without shaking.

[0036] By cooperating with the rotating unit 200 and the spraying unit 300, the spraying unit 300 can perform a circumferential spraying operation on the wheel hub. The spraying points of the spraying unit 300 can cover the upper, middle and lower surfaces of the wheel hub, ensuring that the sprayed paint can cover the wheel hub while rotating, avoiding the traditional manual rotation and adjustment, and making the overall spraying process faster.

[0037] The top of the spraying unit 300 and the rotating unit 200 is fixedly mounted with a support frame 305. The top of the support frame 305 is fixedly mounted with a material guide shell 303. The side of the material guide shell 303 is connected to the spraying rod 301, and the inner wall of the spraying rod 301 is connected to the spray nozzle 302. One side of the hub is located between the spraying rods 301.

[0038] The hoisting unit 400 includes a lower hoisting rod 402, the bottom of which is provided with an installation cavity 4021, and the bottom of the installation cavity 4021 is provided with four sets of installation ports 4022.

[0039] The positioning unit 600 has a clamping member 603 installed inside the mounting port 4022, and a friction contact 604 is fixedly connected to the outside of the clamping member 603. An irregular gear 605 is fixedly connected to the top of the clamping member 603. A second hydraulic telescopic cylinder 601 is fixedly connected to the top inside the mounting cavity 4021, and a square toothed column 602 that meshes with the irregular gear 605 is installed at the bottom of the second hydraulic telescopic cylinder 601.

[0040] During daily operations:

[0041] The lower boom 402 is driven to descend, and its bottom enters the axle of the wheel hub, causing the positioning unit 600 in the mounting cavity 4021 to enter the clamping state. The second hydraulic telescopic cylinder 601 is activated, and the second hydraulic telescopic cylinder 601 drives the irregular gear 605 through the square toothed column 602, causing the irregular gear 605 to drive the clamping part 603 to move in a contracting and expanding motion. The clamping part 603 expands to make itself press against the inner wall of the axle of the wheel hub and clamp it, and then drives the wheel hub to be lifted and transferred.

[0042] When the clamped wheel hub moves between the spray bar 301, the rotating unit 200 can be activated to drive the support frame 305 to rotate synchronously. At that time, the guide shell 303 on the top of the support frame 305 and the spray bar 301 rotate around the wheel hub. Since the nozzle 302 of the spray bar 301 corresponds to the top side and bottom of the wheel hub, the wheel hub can be quickly sprayed under the effect of rotation.

[0043] like Figures 1-6 As shown, in order to enable the scraping component to complete the cleaning of the second guide cavity 2022, the rotating unit 200 further includes a mounting base 202. The mounting base 202 is fixedly connected to the top of the spray chamber 100. An upper turntable 201 is rotatably slidable inside the mounting base 202. A drive shaft 205 connected to the upper turntable 201 is connected to the bottom of the mounting base 202. A motor 203 is fixedly connected to the bottom of the mounting base 202, and the output end of the motor 203 is connected to a pulley 204 that is connected to the drive shaft 205 for transmission.

[0044] Specifically, during operation, the motor 203 is started. With the cooperation of the controller, the motor 203 is transmitted to the drive shaft 205 through the pulley 204, which drives the shaft to rotate. At that time, the upper turntable 201 is rotated in real time, so the spraying unit 300 located on the upper turntable 201 can rotate synchronously.

[0045] During this process, the hoisting point of the wheel hub corresponds to the center of the upper turntable 201, ensuring that the distance between the spraying unit 300 and the wheel hub remains consistent when the upper turntable 201 rotates.

[0046] like Figures 1-6As shown, in order to enable the scraping component to complete the cleaning of the second guide cavity 2022, a mounting base 304 is fixedly installed on the top of the support frame 305, and the guide shell 303 is fixedly installed on the top of the mounting base 304. A liquid guide cavity 310 is fixedly connected to the bottom of the mounting base 202. A mounting connector 308 communicating with the drive shaft 205 is connected to the top of the liquid guide cavity 310. The mounting connector 308 is rotatably connected to the drive shaft 205. A guide square tube 309 is connected to one side of the mounting base 202. The guide square tube 309 is connected to the liquid guide cavity 310 through a branch pipe. A guide connector 307 communicating with the drive shaft 205 is connected to the top of the upper turntable 201. A communicating metal conduit 306 is rotatably connected to the top of the guide connector 307. The other end of the metal conduit 306 is connected to the guide shell 303.

[0047] Specifically, the support frame 305 supports and installs the top component through the mounting base 304 on its own, ensuring that the guide shell 303 can sit on the mounting base 304;

[0048] During this process, when the upper turntable 201 rotates, the metal conduit 306 is rotated and connected to the material guide connector 307 to avoid interference with the material guide square tube 309 when the upper turntable 201 rotates. When the upper turntable 201 drives the support frame 305 to rotate, the metal conduit 306 at the bottom of the material guide shell 303 will also rotate. In order to avoid structural interference between the metal conduit 306 and the material guide square tube 309, the paint is transported through the hollow drive shaft 205 and rotated and transported through the material guide connectors 307 and the mounting connectors 308 at both ends of the drive shaft 205. The material guide square tube 309 transports the paint into the liquid guide cavity 310 and then into the drive shaft 205. This ensures that the material guide square tube 309 guides the paint to the metal conduit 306 and that the upper turntable 201 drives the top support facility to rotate, thus completing the rotary spraying operation of the equipment.

[0049] Furthermore, an electric slide rail 500 is fixedly installed on the top of the spray booth 100, and a slider 501 is slidably installed on the electric slide rail 500, with the hoisting unit 400 installed at the bottom of the slider 501.

[0050] Specifically, the wheel hub to be sprayed is guided to the spraying area by the electric slide rail 500, and the slider 501 slides on the electric slide rail 500 to drive the bottom component to move in real time, thus completing the hoisting and movement of the wheel hub.

[0051] It is worth noting that the electric slide rail 500 and slider 501 are the guiding mechanisms in the production workshop, enabling the hoisted wheel hubs to be transferred between various process areas.

[0052] To enable the hoisting unit 400 to enter or exit the positioning unit 600's working state, the hoisting unit 400 further includes an upper hoisting rod 401 and a hydraulic telescopic cylinder 403. The upper hoisting rod 401 is fixedly installed at the bottom of the slider 501, and the hydraulic telescopic cylinder 403 is fixedly connected inside the upper hoisting rod 401. The lower hoisting rod 402 is sleeved and connected to the upper hoisting rod 401, and the top of the lower hoisting rod 402 is installed and connected to the output end of the hydraulic telescopic cylinder 403.

[0053] Specifically, when the positioning unit 600 enters the working state, the hydraulic telescopic cylinder 403 is activated, which pushes the lower rod 402. At that time, the bottom of the lower rod 402 can enter or exit the positioning state. By using the telescopic movement of the lower rod 402 on the upper rod 401, the positioning unit 600 is prompted to enter or exit the center of the wheel hub.

[0054] The lower suspension rod 402 and the upper suspension rod 401 are fitted together, like a telescopic sleeve structure.

[0055] Furthermore, movable shafts 606 are installed on both sides of the clamping component 603, and the clamping component 603 is movably connected to the mounting port 4022 through the movable shafts 606.

[0056] During this period, when the hydraulic telescopic cylinder 601 drives the square toothed column 602 to drive the meshing irregular gear 605, since the irregular gear 605 is fixedly connected to the clamping member 603, the clamping member 603 can use its own movable shaft 606 to perform positioning movement in the mounting port 4022, causing the clamping member 603 to perform expansion and contraction movements within the mounting port 4022. When contracting, the clamping member 603 exits the clamping positioning, and when expanding, it enters the built-in clamping positioning.

[0057] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
