Description

Technical Field

[0001] The invention relates to the technical field of wheel hub polishing machines, in particular to a wheel hub surface grinding device. Background Art

[0002] During the manufacturing process of the wheel hub, there will be defects such as burrs or scratches on its surface. In order to improve the smoothness and aesthetics of the wheel hub surface, a wheel hub polishing machine is generally used to polish the wheel hub surface to remove scratches, blemishes and oxide scale on the wheel hub surface, making the wheel hub surface smoother and brighter.

[0003] For example, the patent with the patent authorization announcement number CN216707092U discloses a wheel hub polishing machine, including a frame, a horizontal straight-edge motor, a hollow rotary oil cylinder, an oil cylinder connecting rod, a rotating spindle, a vertical bearing, a three-jaw chuck, a sprocket assembly A, a lifting oil cylinder, a lifting plate, a positioning pin, a rotating plate, a cylinder, a seat frame, a vertical drum, a drum support plate, a flange bearing plate, a drum bottom shaft, a sprocket assembly B, a vertical motor, a control cabinet, and a hydraulic station. This type of wheel hub polishing machine is easy to operate, and one person can now replace the original one-line cleaning process; the product has a consistent finish after polishing for a fixed time, which improves production and qualification rate; it is placed in the back process of the CNC machine tool to reduce the intermediate handling process and safety hazards; and it improves environmental pollution through regular water changes and reasonable discharge.

[0004] Although the wheel polishing machine in the above patent reduces the intermediate transportation process and safety hazards, it still has certain defects: during the grinding process, the wheel hub is generally tilted and placed in the grinding barrel, and in order to avoid the wheel hub from contacting the bottom of the grinding barrel and causing damage to the wheel hub, a certain distance is left between the wheel hub and the bottom of the grinding barrel, which makes it difficult for the abrasive located at this position to contact the wheel hub, and the damage rate of this part of the abrasive is also much lower than the damage rate of the abrasive on the upper layer of the grinding barrel. However, due to the small size of the abrasive, after the abrasive on the upper layer of the grinding barrel is damaged, the staff will replace all the abrasives together, which will cause waste and is not conducive to reducing costs.

[0009] Furthermore, the thickness of the inner ring of the outer guide ring is smaller than that of the outer ring, a first retaining ring is fixedly connected to the middle position of the outer guide ring, a plurality of first leakage holes distributed at equal intervals are provided on the first retaining ring, a second retaining ring is fixedly connected to the outer side of the inner guide ring, a plurality of second leakage holes distributed at equal intervals are provided on the second retaining ring, and the cross-section of the first leakage hole is equal to the cross-section of the second leakage hole.

[0010] Furthermore, a material discharge channel is fixedly connected to the upper end of the conveying shell, one end of the material discharge channel matches with the material discharge opening of the conveying shell, and the other end of the material discharge channel matches with the second retaining ring.

[0011] Furthermore, a water inlet is fixedly connected to the top of the conveying shell, a sealing cover is threadedly connected to the top of the water inlet, and a material guide push plate is fixedly connected to the outer wall of the lower end of the conveying shell.

[0012] Furthermore, a discharge groove is provided at the bottom of the polishing barrel, a discharge pipe is fixedly connected to the lower end of the outer wall of the polishing barrel, the discharge pipe matches the discharge groove, and a blocking rod is slidably connected to the inside of the discharge groove.

[0013] Furthermore, the end of the blocking rod away from the conveying shell is fixedly connected to a plurality of equidistantly distributed positioning rods, the end of the discharge pipe away from the polishing barrel is provided with a plurality of equidistantly distributed positioning holes, the positioning holes match the positioning rods, and the end of the blocking rod away from the conveying shell is fixedly connected to a gripping block.

[0014] Furthermore, one end of the blocking rod away from the polishing barrel is rotatably connected to a threaded sleeve, the threaded sleeve is threadedly connected to the discharge pipe, and a plurality of equidistantly distributed toggle blocks are fixedly connected to the outer wall of the threaded sleeve.

[0017] 2. In this hub surface grinding device, only when the first leakage hole on the first retaining ring is aligned with the second leakage hole on the second retaining ring, the abrasive will flow into the conveying shell through the first leakage hole and the second leakage hole. This can prevent a large amount of abrasive from accumulating between the inner guide ring and the outer guide ring, causing blockage or damage to the equipment, thereby affecting the normal turning of the abrasive.

[0018] 3. In this type of hub surface grinding device, when the motor drives the conveying auger to rotate, the driving gear will drive the transmission gear to rotate, and the transmission gear will drive the polishing barrel to rotate through the tooth block. In this way, when the conveying auger is conveying abrasives, the abrasives will be evenly dispersed by the polishing barrel, avoiding the abrasives from accumulating in one place after flowing out of the conveying shell, resulting in large differences in the abrasive wear rates at various parts of the polishing barrel.

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] See also Figures 1 to 10 A wheel hub surface grinding device comprises a base 2 and a plurality of polishing machine bodies 1 equidistantly distributed around the base 2. A polishing barrel 5 is rotatably connected to the top of the base 2. A conveying shell 13 fixed to the base 2 is rotatably connected to the middle position of the polishing barrel 5. A motor 10 is fixed to the middle position of the bottom of the base 2. A conveying auger 12 is fixed to the output end of the motor 10. The conveying auger 12 is located inside the conveying shell 13, and the conveying auger 12 is rotatably connected to the conveying shell 13. A feeding port is provided on one side of the lower end of the conveying shell 13, and a unloading port is provided on the other side of the upper end of the conveying shell 13. An inner guide ring 14 is fixed to the lower end of the outer wall of the conveying shell 13, an outer guide ring 6 is fixed to the lower end of the inner wall of the polishing barrel 5, and a transmission assembly is connected to the top of the base 2.

[0032] In the wheel hub surface grinding device of the present invention, when the polishing machine body 1 is working normally, the outer guide ring 6 and the inner guide ring 14 will guide the abrasive in the lower layer of the polishing barrel 5 to the feed inlet position of the conveying shell 13, and enter the interior of the conveying shell 13 through the feed inlet, and the motor 10 will drive the conveying auger 12 to rotate, and the abrasive entering the conveying shell 13 will be conveyed to the discharge port position through the conveying auger 12, and will eventually flow out of the conveying shell 13 and fall into the upper layer position of the polishing barrel 5, thereby realizing the turning of the abrasive, so that the abrasive in the polishing barrel 5 has a chance to contact with the wheel hub 29, and the abrasive The wear rate will be more uniform, and when replacing the abrasive, it is not easy for the wear degree of the lower abrasive of the polishing barrel 5 to be much lower than the wear degree of the upper abrasive of the polishing barrel 5. At the same time, the motor 10 is connected to the control system (such as control buttons or control panel) of the polishing machine body 1. Since the control system is a mature product, it is not described in detail here. In addition, the structure of the polishing machine body 1 in the present invention is similar to the prior art, and a wheel polishing machine structure disclosed in the patent with patent authorization announcement number CN216707092U is similar, so it will not be elaborated on here.

[0033] As a preferred technical solution of the present invention, the transmission assembly includes a transmission gear 9 and a driving gear 11. A plurality of tooth blocks are fixed to the lower end of the inner side of the polishing barrel 5. The transmission gear 9 is rotatably connected to the base 2. The transmission gear 9 and the tooth blocks are meshed with each other. The driving gear 11 is located below the conveying auger 12, and the driving gear 11 and the transmission gear 9 are meshed with each other.

[0034] Specifically, when the motor 10 drives the conveying auger 12 to rotate, the motor 10 will also drive the driving gear 11 to rotate, and the driving gear 11 will drive the transmission gear 9 meshing therewith to rotate. When the transmission gear 9 rotates, it will drive the tooth block to move, and the gear will drive the polishing barrel 5 to rotate. When the polishing barrel 5 rotates, the abrasive will be dispersed, so that the wear rate of each layer of abrasive in each place in the polishing barrel 5 is more uniform.

[0035] As a preferred technical solution of the present invention, a ring-shaped limit groove 3 is provided on the top of the base 2, and a limit ring 4 is fixed to the bottom of the polishing barrel 5. The limit ring 4 matches the limit groove 3, and the cross section of the limit ring 4 is a trapezoidal setting. The polishing barrel 5 is restricted by the limit groove 3 and the limit ring 4, so that the polishing barrel 5 is more stable when rotating.

[0036] As a preferred technical solution of the present invention, the thickness of the inner ring of the outer guide ring 6 is smaller than that of the outer ring, a first retaining ring 7 is fixedly connected to the middle position of the outer guide ring 6, a plurality of first leakage holes 8 distributed at equal intervals are provided on the first retaining ring 7, a second retaining ring 15 is fixedly connected to the outer side of the inner guide ring 14, a plurality of second leakage holes 16 distributed at equal intervals are provided on the second retaining ring 15, and the cross-section of the first leakage hole 8 is equal to the cross-section of the second leakage hole 16.

[0037] Specifically, only when the first leakage hole 8 is aligned with the second leakage hole 16, the abrasive will pass through the first leakage hole 8 and the second leakage hole 16 and fall between the outer guide ring 6 and the inner guide ring 14, while when the first leakage hole 8 and the second leakage hole 16 are staggered, it is difficult for the abrasive to enter between the outer guide ring 6 and the inner guide ring 14. This can avoid excessive abrasive between the outer guide ring 6 and the inner guide ring 14, which will cause the abrasive to be blocked and difficult to enter the conveying shell 13.

[0038] As a preferred technical solution of the present invention, a material discharge channel 18 is fixedly connected to the upper end of the conveying shell 13 , one end of the material discharge channel 18 matches the material discharge port of the conveying shell 13 , and the other end of the material discharge channel 18 matches the second retaining ring 15 .

[0039] Specifically, the abrasive is transported to the middle position between the outer wall of the conveying shell 13 and the inner wall of the polishing barrel 5 through the discharge channel 18. Then, when the polishing barrel 5 rotates, the abrasive located at the middle position between the outer wall of the conveying shell 13 and the inner wall of the polishing barrel 5 will contact the hub 29, thereby dispersing the abrasive, so as to facilitate maintaining a relatively uniform degree of wear on all the abrasives.

[0040] As a preferred technical solution of the present invention, a water injection port 19 is fixedly connected to the top of the conveying shell 13 , a sealing cover 20 is threadedly connected to the top of the water injection port 19 , and a material guide push plate 17 is fixedly connected to the outer wall of the lower end of the conveying shell 13 .

[0041] Specifically, when it is necessary to take out the abrasive from the conveying auger 12 and the conveying shell 13, the sealing cover 20 can be opened, and then clean water can be injected into the conveying shell 13 through the water injection port 19 to flush out the abrasive. At the same time, since the material guide push plate 17 will not move when the polishing barrel 5 rotates, the abrasive entering between the outer guide ring 6 and the inner guide ring 14 will be guided and restricted by the material guide push plate 17, making it easier for the abrasive to enter the conveying shell 13.

[0042] As a preferred technical solution of the present invention, a discharge groove 21 is opened at the bottom of the polishing barrel 5, and a discharge pipe 22 is fixedly connected to the lower end of the outer wall of the polishing barrel 5. The discharge pipe 22 matches the discharge groove 21, and a sealing rod 24 is slidably connected inside the discharge groove 21.

[0043] As a preferred technical solution of the present invention, the end of the blocking rod 24 away from the conveying shell 13 is fixedly connected to a plurality of equidistantly distributed positioning rods 25, the end of the discharge pipe 22 away from the polishing barrel 5 is provided with a plurality of equidistantly distributed positioning holes 23, the positioning holes 23 match the positioning rods 25, and the end of the blocking rod 24 away from the conveying shell 13 is fixedly connected to a gripping block 28.

[0044] As a preferred technical solution of the present invention, the end of the blocking rod 24 away from the polishing barrel 5 is rotatably connected to a threaded sleeve 26, the threaded sleeve 26 is threadedly connected to the discharge pipe 22, and the outer wall of the threaded sleeve 26 is fixed with multiple equidistantly distributed toggle blocks 27.

[0045] Specifically, when the abrasive in the polishing barrel 5 needs to be taken out, the threaded sleeve 26 can be rotated first to remove the threaded sleeve 26 from the discharge pipe 22, and then the blocking rod 24 can be pulled out from the discharge groove 21, and then flushed with clean water to allow the abrasive to flow out of the polishing barrel 5 through the discharge groove 21 and the discharge pipe 22. After all the abrasive has flowed out, the positioning rod 25 can be aligned with the positioning hole 23, and then the blocking rod 24 can be inserted into the discharge groove 21, and finally the threaded sleeve 26 can be rotated to make the threaded sleeve 26 and the discharge pipe 22 threadedly connected. The discharge groove 21 is blocked by the blocking rod 24 to prevent abrasive from entering the discharge groove 21 when the polishing barrel 5 is working.

[0046] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
