Description

Technical Field

[0001] The invention relates to the technical field of wheel hub assembly, in particular to a two-section spliced ​​aluminum alloy wheel hub and a splicing method thereof. Background Art

[0002] The wheel hub is a cylindrical metal component whose center is mounted on an axle and whose inner profile supports the tire. When assembling the wheel hub, the rim and spokes must be assembled. However, since the spokes have a certain weight, it is time-consuming and laborious to carry them to the rim manually.

[0003] The prior art discloses a Chinese patent with application number CN202411490670.6, which is a wheel hub conveying device for electric vehicle assembly. It also discloses that by wrapping a support belt around the outside of the wheel hub, the protection of the conveying wheel hub can be improved, and direct collision between two adjacent wheel hubs can be avoided during the conveying process, thereby helping to reduce the wear of the conveying wheel hub.

[0004] The above-mentioned device can transport the wheel hub during assembly to avoid wear of the wheel hub. However, when assembling the spokes and rims of the automobile wheel hub, manual handling is usually adopted, which will generate greater labor intensity, and the screws between the spokes and the rim cannot be quickly adjusted when they are docked. At the same time, when fixing with screws, it is necessary to manually spray the screw glue on the bottom of the screws, which brings inconvenience to the assembly of the wheel hub.

The side of the regulating plate away from the rotating ring is rotatably connected to the moving part, and the multiple moving parts are respectively fixedly connected to the corresponding fastening frames.

[0017] The splicing method of aluminum alloy wheels includes the following steps:

[0018] S1: Rim fixing:

[0019] The rim of the required spliced ​​wheel hub is placed at the center of the turntable, and then the electric slider is turned on to drive the rotating ring to rotate. When the rotating ring rotates, the moving part is driven to slide through the control plate, and finally multiple fastening frames clamp the outer wall of the rim;

[0020] S2: Spoke down:

[0021] The hydraulic rod retracts to drive the annular frame downward, and after the support plate moves into the through-hole, the hydraulic rod pushes upward to drive the annular frame upward. At this time, the center rod moves out of the middle of the spoke when moving upward, and the spoke falls onto the rim;

[0022] S3: Screw hole fixation:

[0023] The inner tube moves to the screw hole that overlaps between the rim and the spoke, and when the L-shaped frame drives the inner tube to move downward, the L-shaped frame presses the sliding rod, and the sliding rod moves downward after being pressed. At this time, the sliding rod drives the extrusion rod to press down in the glue coating tube, and the lower part of the screw is sprayed with screw glue. Then the screwdriver rotates the screw in the screw hole to fix the rim and the spoke.

[0024] Beneficial effects of the present invention:

[0025] 1. The present invention can clamp the rim on the turntable by moving a plurality of fastening frames closer together. At the same time, the movement between the plurality of fastening frames can meet the fixation of rims of different diameters during assembly, making it more widely used in assembling the wheel hub. The annular frame is driven downward by the retraction of the hydraulic rod. When the annular frame moves downward, the spokes sleeved on the outside of the center rod are placed on the rim. By rotating the spokes on the supporting plate, the screw holes between the spokes and the rim can be easily and quickly docked for subsequent fixation. Compared with the existing device, the present invention does not need to manually place the spokes on the rim, and can quickly and portablely align the plurality of screw holes between the rim and the spokes to keep them on the same axis, effectively solving the problem of manual handling of the spokes during assembly of the wheel hub.

[0026] 2. The present invention starts the electric push rod to move its telescopic end downward, and the telescopic end of the electric push rod drives the extrusion member to move downward to squeeze multiple pallets. Since one side of the pallet is in contact with the extrusion member, the multiple pallets are squeezed and move away from each other. At this time, the multiple pallets move out of the through-opening, which is convenient for supporting the spokes before docking. When the spokes are docked with the rim, the electric push rod is turned on and moved upward. At this time, the extrusion member cancels the squeezing of the multiple pallets. Under the action of the spring, the multiple pallets move closer to each other. At this time, the multiple pallets move into the through-opening respectively, and the spokes slide and fall at the bottom of the center rod, and then fall onto the rim for subsequent assembly.

[0027] 3. The present invention drives the rotating wheel to rotate by opening the electric slider, and the rotation of the rotating wheel drives the limiting rod to rotate. When the limiting rod rotates, the restriction on the lowest spoke on the center rod is cancelled, and then the spoke slides onto multiple supporting plates, waiting to be aligned and assembled with the next rim.

[0028] 4. The present invention drives the swing plate to rotate left and right by turning on the motor. When the swing plate rotates left and right, the L-shaped frame drives the limiting member to slide in the guide groove. The setting of the limiting member enables the L-shaped frame to move up and down while moving left and right. When the L-shaped frame drives the inner cylinder to move above the screw, the screwdriver in the inner cylinder can absorb and pick up the screw below it. Then, under the swing of the swing plate, the inner cylinder moves to the screw hole overlapped between the rim and the spoke, and when the L-shaped frame drives the inner cylinder to move downward, the L-shaped frame presses the slide The rod and the slide rod move downward after being pressed, and the slide rod drives the extrusion rod to press down in the glue coating tube at this time, and the screw glue in the glue coating tube is sprayed on the lower part of the screw adsorbed in the internal tube through the spray tube, so that when the rim and the spoke are assembled by screw fastening, the screw glue is sprayed on the lower part of the screw, and the electric slider is opened to drive the turntable to rotate, so that the screw hole is replaced, and the above operation is repeated, so that the screws can be fastened to multiple screw holes continuously when the rim and the spoke are assembled.

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] A two-section spliced ​​aluminum alloy wheel hub and a splicing method thereof are used to assemble a wheel hub for special products and special purposes. The invention assembles the rim and the spokes in the assembly wheel hub. The invention quickly connects the screw holes of the spokes with the screw holes on the rim during installation, and sprays screw glue on the outside of the screws during assembly.

[0044] like Figure 1-Figure 10 As shown, a method for splicing a two-section aluminum alloy wheel hub comprises a support platform 1, a turntable 10 is rotatably installed in the middle of the upper end surface of the support platform 1 through an electric slider, a rim to be assembled is placed in the middle of the turntable 10, a fastening frame 105 for fixing and limiting the rim when the wheel hub is spliced ​​is slidably installed in the center of the turntable 10 in an annular direction, a hydraulic rod 20 is circumferentially installed on the upper end surface of the turntable 10, and an annular frame 2 is fixedly installed on the telescopic ends of multiple hydraulic rods 20, a center rod 21 is detachably installed in the middle of the annular frame 2, a spoke is sleeved on the outside of the center rod 21, a hollow groove 210 is opened in the middle of the lower side of the center rod 21, a through opening is opened on the outer side of the hollow groove 210, a supporting plate 213 is slidably installed in the through opening, and the supporting plate 213 is used to support the spoke to be assembled when it passes through the through opening, an automatic lowering component is circumferentially arranged on the inner side of the annular frame 2, a protective component is circumferentially arranged on the lower end surface of the annular frame 2, and an assembly unit is arranged on one side of the upper end surface of the support platform 1.

[0045] A non-slip rubber pad is provided on one side of the fastening frame 105 close to the rim. The rim on the turntable 10 can be clamped by moving the multiple fastening frames 105 closer to each other. At the same time, the movement between the multiple fastening frames 105 can meet the fixation of rims of different diameters during assembly, making it more widely used in assembling the wheel hub. The annular frame 2 is driven downward by the retraction of the hydraulic rod 20. When the annular frame 2 moves downward, the spokes sleeved on the outside of the center rod 21 are placed on the rim, and the screw holes between the spokes and the rim can be easily and quickly fixed by rotating the spokes on the support plate 213. Docking for subsequent fixation, compared with the existing device, the present invention does not need to manually place the spokes on the rim, and can quickly and portablely align multiple screw holes between the rim and the spokes to keep them on the same axis, effectively solving the problem of manual handling of the spokes during hub assembly. After the support plate 213 is moved into the through-opening, the hydraulic rod 20 is pushed upward to drive the annular frame 2 to move upward. At this time, the center rod 21 moves out of the middle of the spoke when moving upward, and the spoke falls onto the rim. The spoke and rim can be assembled after docking through the setting of the assembly unit.

[0046] An electric push rod 211 is fixedly installed on the top of the inner cavity of the hollow groove 210, and an inverted cone-shaped extrusion piece 212 is fixedly installed on the telescopic end of the electric push rod 211. The side of the support plate 213 close to the extrusion piece 212 is set in a triangular hypotenuse. A spring is commonly connected between one side of the lower end surface of the support plate 213 and the hollow groove 210. The support plate 213 is telescopically slid in the hollow groove 210, thereby eliminating the resistance of the support plate 213 to the spokes, allowing the spokes to slide along the center rod 21 to the rim.

[0047] By turning on the electric push rod 211 to make its telescopic end move downward, the telescopic end of the electric push rod 211 drives the extrusion piece 212 to move downward to squeeze multiple support plates 213. Since one side of the support plate 213 is in contact with the extrusion piece 212, the multiple support plates 213 are squeezed and move away from each other. At this time, the multiple support plates 213 move out of the through-hole, which is convenient for supporting the spokes before docking. When the spokes are docked with the rim, the electric push rod 211 is turned on and moved upward. At this time, the extrusion piece 212 cancels the squeezing of the multiple support plates 213. Under the action of the spring, the multiple support plates 213 move closer to each other. At this time, the multiple support plates 213 move into the through-holes respectively, and the spokes slide and fall at the lower part of the center rod 21, and then fall onto the rim for subsequent assembly.

[0048] A fastening rod 22 is circumferentially and slidably installed on the upper side of the annular frame 2. The fastening rod 22 penetrates and slides through the side wall of the annular frame 2. A rectangular groove corresponding to the fastening rod 22 is circumferentially provided on the outer side of the central rod 21. Fixed members 221 are fixedly installed on the closer sides of the plurality of fastening rods 22. The side of the fixed member 221 away from the fastening rod 22 is clamped with the rectangular groove. When the plurality of fixed members 221 are placed in the rectangular groove, the central rod 21 is fixed at the center of the annular frame 2.

[0049] By pulling the fastening rod 22, when the fastening rod 22 moves outwards, it synchronously drives the fixed member 221 to move, thereby moving the fixed member 221 out of the rectangular groove, so as to facilitate sleeving a plurality of spokes to be assembled on the outside of the central rod 21.

[0050] The automatic lowering assembly includes a plurality of inner side plates 24 circumferentially installed on the inner wall of the annular frame 2. Rotating wheels 241 are provided on the closer sides of the plurality of inner side plates 24. The rotating wheels 241 and the inner side plates 24 are rotationally connected through electric sliders. A plurality of limiting rods 242 are circumferentially provided on one side of the rotating wheel 241. The plurality of limiting rods 242 can intermittently lower spokes with different thicknesses and different diameters.

[0051] When automatically lowering the spokes, the electric slider is turned on to drive the rotating wheel 241 to rotate. When the rotating wheel 241 rotates, it drives the limiting rod 242 to rotate. When the limiting rod 242 rotates, the restriction on the lowermost spoke on the central rod 21 is cancelled. Subsequently, the spoke slides down onto a plurality of support plates 213, so as to wait for alignment and assembly with the next rim.

[0052] The protection assembly includes a U-shaped member 23. The U-shaped member 23 is circumferentially arranged on the lower side of the annular frame 2. A cross bar 231 is horizontally and fixedly installed in the middle of the U-shaped member 23. A cylinder 232 connected to the annular frame 2 is provided above the U-shaped member 23. One end of the cylinder 232 away from the annular frame 2 is hinged with a moving frame 233. A through groove 234 sleeving the cross bar 231 is opened in the middle of the moving frame 233. A clamping plate 235 is fixedly installed at one end of the moving frame 233 away from the cylinder 232. A plurality of inclined grooves corresponding to the clamping plate 235 are opened on the central rod 21. When the clamping plate 235 is clamped in the inclined groove, the lower part of the central rod 21 is fixed. Through the clamping plate 235 and the fixed member 221, the central rod 21 can be doubly stabilized in the annular frame 2. And when the clamping plate 235 is in the inclined groove, the plurality of moving frames 233 can resist the spokes in the automatic lowering assembly to prevent the spokes from falling off.

[0053] By turning on and pushing forward a plurality of cylinders 232, when the cylinders 232 are pushed forward, they drive the plurality of moving frames 233 to move away from each other. When the plurality of moving frames 233 move away from each other, the corresponding plurality of clamping plates 235 are moved out of the inclined grooves, so as to facilitate the spokes sleeved on the central rod 21 to slide down onto the support plates 213.

[0057] The motor is turned on to drive the swing plate 301 to rotate left and right. When the swing plate 301 rotates left and right, the L-shaped frame 304 drives the limiting member 303 to slide in the guide groove 302. The setting of the limiting member 303 can make the L-shaped frame 304 move up and down while moving left and right. When the L-shaped frame 304 drives the internal cylinder 306 to move above the screw 383, the screwdriver in the internal cylinder 306 can absorb and pick up the screw 383 below it. Then, under the swing of the swing plate 301, the internal cylinder 306 moves to the screw hole that overlaps between the rim and the spoke, and when the L-shaped frame 304 drives the internal cylinder 306 to move downward, the L-shaped frame 304 presses the sliding rod 32, and the sliding rod 32 moves downward after being pressed. At this time, the sliding rod 32 drives the extrusion The rod 37 is pressed downward in the glue coating tube 35, and at this time, the screw glue in the glue coating tube 35 is sprayed on the lower part of the screw 383 adsorbed in the internal tube 306 through the spray tube 36, so that when the rim and the spoke are fastened and assembled by the screw 383, the screw glue is sprayed on the lower part of the screw 383, and the electric slider is opened to drive the turntable 10 to rotate, so that the screw hole is replaced, and the above operation is repeated to continuously fasten the screws 383 on multiple screw holes when assembling between the rim and the spoke. Compared with the existing device, the present application does not need to manually spray the screw glue on the outside of the screw 383, and after fixing a screw hole between the rim and the spoke, multiple screw holes can be assembled continuously.

[0058] A supporting frame 38 is fixedly installed at the lower part of one side of the support frame 30, and a rotating frame 381 is installed in the middle of the supporting frame 38 through a motor.

Adjustment grooves 102 are provided on the turntable 10 on the side away from the multiple regulating plates 103. A moving part 104 is slidably installed in the adjusting groove 102. The side of the regulating plate 103 away from the rotating ring 101 is rotatably connected to the moving part 104, and the multiple moving parts 104 are respectively fixedly connected to the corresponding fastening frames 105.

[0060] The electric slider is opened to drive the rotating ring 101 to rotate, and when the rotating ring 101 rotates, the multiple regulating plates 103 are synchronously driven to rotate. When the multiple regulating plates 103 rotate, the moving member 104 is displaced in the adjusting slot 102. When the moving member 104 is displaced, the multiple fastening frames 105 can be moved closer to or away from each other, thereby achieving fixation of the rim during assembly.

[0061] The splicing method of aluminum alloy wheels includes the following steps:

[0062] S1: Rim fixing:

[0063] The wheel rim of the required spliced ​​wheel hub is placed at the center of the turntable 10, and then the electric slider is turned on to drive the rotating ring 101 to rotate. When the rotating ring 101 rotates, the moving part 104 is driven to slide through the regulating plate 103, and finally the multiple fastening frames 105 clamp the outer wall of the wheel rim;

[0064] S2: Spoke down:

[0065] The hydraulic rod 20 retracts to drive the annular frame 2 to move downward, and after the support plate 213 moves into the through opening, the hydraulic rod 20 pushes upward to drive the annular frame 2 to move upward. At this time, the center rod 21 moves out of the middle of the spoke when moving upward, and the spoke falls onto the rim;

[0066] S3: Screw hole fixation:

[0067] The inner tube 306 moves to the screw hole that overlaps between the rim and the spoke, and when the L-shaped frame 304 drives the inner tube 306 to move downward, the L-shaped frame 304 presses the slide bar 32, and the slide bar 32 moves downward after being pressed. At this time, the slide bar 32 drives the extrusion rod 37 to press down in the glue coating tube 35, and the lower part of the screw 383 is sprayed with screw glue. Then the screwdriver rotates the screw 383 in the screw hole to fix the rim and the spoke.

[0068] When the present invention is in use, the fastening rod 22 is pulled, and when the fastening rod 22 moves outward, the fixing member 221 is simultaneously driven to move, and then the fixing member 221 is moved out of the rectangular groove, so that it is convenient to sleeve a plurality of spokes to be assembled on the outside of the center rod 21, and then the pulling of the fastening rod 22 is canceled, so that the fixing member 221 fixes the center rod 21, and the rim is placed at the center of the turntable 10, and the electric slider is turned on to drive the rotating ring 101 to rotate, and when the rotating ring 101 rotates, it simultaneously drives the plurality of regulating plates 103 to rotate, and when the plurality of regulating plates 103 rotate, the moving member 104 is displaced in the regulating groove 102, and when the moving member 104 is displaced, the plurality of fastening frames 105 can be brought close to each other, so that the rim is fixed when assembled;

[0069] The annular frame 2 is driven downward by the retraction of the hydraulic rod 20. When the annular frame 2 moves downward, the spokes sleeved on the outside of the center rod 21 are placed on the rim, and by rotating the spokes on the support plate 213, the screw holes between the spokes and the rim can be easily and quickly docked for subsequent fixation. Compared with the existing device, the present invention does not need to manually place the spokes on the rim, and can quickly and portablely align multiple screw holes between the rim and the spokes to keep them on the same axis, effectively solving the problem of manual handling of the spokes during hub assembly. After the support plate 213 is moved into the through opening, the hydraulic rod 20 is then pushed upward to drive the annular frame 2 to move upward. At this time, the center rod 21 moves out of the middle of the spoke when moving upward, and the spoke falls onto the rim.

[0070] The motor is turned on to drive the swing plate 301 to rotate left and right. When the swing plate 301 rotates left and right, the limiting member 303 is driven to slide in the guide groove 302 through the L-shaped frame 304. The setting of the limiting member 303 can make the L-shaped frame 304 move up and down while moving left and right. When the L-shaped frame 304 drives the internal cylinder 306 to move above the screw 383, the screwdriver in the internal cylinder 306 can absorb and pick up the screw 383 below it. Then, under the swing of the swing plate 301, the internal cylinder 306 moves to the rim and the wheel rim. In the overlapping screw holes between the spokes, and when the L-shaped frame 304 drives the inner tube 306 to move downward, the L-shaped frame 304 presses the slide bar 32, and the slide bar 32 moves downward after being pressed. At this time, the slide bar 32 drives the extrusion rod 37 to press down in the glue coating tube 35. At this time, the screw glue in the glue coating tube 35 is sprayed on the lower part of the screw 383 adsorbed in the inner tube 306 through the spraying tube 36, thereby realizing the screw glue spraying on the lower part of the screw 383 when the rim and the spoke are fastened and assembled by the screw 383;

[0071] The electric slider is opened to drive the turntable 10 to rotate, so that the screw holes are replaced, and the above operation is repeated to continuously tighten the screws 383 when assembling the rim and the spokes. Compared with the existing device, the present application does not need to manually spray the screw glue on the outside of the screw 383. At the same time, after fixing a screw hole between the rim and the spoke, multiple screw holes can be assembled continuously. When the spokes are automatically lowered, the electric slider is opened to drive the rotating wheel 241 to rotate. When the rotating wheel 241 rotates, it drives the limiting rod 242 to rotate. When the limiting rod 242 rotates, the restriction on the lowest spoke on the center rod 21 is cancelled, and then the spokes slide onto multiple support plates 213, waiting to be assembled with the next rim.

[0072] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
