[0005] 2. During the polishing of the wheel hub, the debris and dust generated during polishing were not collected, causing the debris and dust to be scattered in the external environment, which is environmentally unfriendly. Utility Model Content

[0006] This utility model provides a polishing device for automobile wheel hub production, which solves the problems of the polishing device proposed in the prior art, which relies on the angle adjustment of the mounting plate to polish the wheel hub, resulting in the polishing wheel only being able to polish a small area of ​​the wheel hub, which is not practical, and does not collect the debris and dust generated during polishing, causing the debris and dust to be scattered in the external environment, which is not environmentally friendly.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A polishing device for automobile wheel hub production includes an operating table and a wheel hub. The operating table has a rotating mechanism on its top, comprising a rotating platform connected to the outer wall of the operating table top via bearings, a mounting cylinder fixed to the outer wall of the rotating platform top, and a rotary motor bolted to the inner wall of the operating table top. The mounting cylinder has three clamping assemblies, each including an electric push rod and a clamping block bolted to one end of the output shaft of the electric push rod. The operating table has a lifting mechanism, comprising a rotating frame rotatably mounted on both outer walls of the operating table, a lifting cylinder bolted to the outer wall of the rotating frame top, and a lifting plate bolted to the bottom end of the piston rod of the lifting cylinder. The rotating frame contains an adjustment assembly, which includes an adjustment cylinder and a bolted-to-one connection to the piston rod of the adjustment cylinder. The system includes an installation frame, two connecting blocks fixed to the top outer wall of the installation frame, an adjusting motor bolted to one side outer wall of the installation frame, a screw connected to one end of the output shaft of the adjusting motor via a coupling, and a threaded block bolted to the outer wall of the screw. The bottom of the threaded block is equipped with a polishing assembly, which includes a connecting frame bolted to the bottom outer wall of the threaded block, a polishing motor bolted to the bottom inner wall of the connecting frame, and a polishing wheel. The operating table is equipped with a dust removal mechanism, which includes a support plate bolted to the middle inner wall of the operating table, a limiting frame fixed to the top outer wall of the support plate, a collection box slidably fitted within the limiting frame, a fan bolted to one side outer wall of the collection box, a box cover bolted to the top outer wall of the collection box, and a filter bolted to the top outer wall of the box cover.

[0009] Preferably, a gear ring is connected to the outer wall of the middle part of the rotary table by a pin, and a gear is connected to the outer wall of the upper part of the output shaft of the rotary motor by a pin, and the gear and the gear ring mesh with each other to form a transmission engagement.

[0010] Preferably, a mounting block is bolted to the outer wall of the middle part of the mounting cylinder, and the electric push rod is bolted to the outer wall of the mounting block. Several anti-slip grooves are opened on the arc-shaped surface of the clamping block.

[0011] The above scheme uses a rotary table to support the wheel hub. Then, three electric push rods move to transport the clamping block to the outer wall of the middle part of the wheel hub, so that the clamping block contacts the outer wall of the middle part of the wheel hub and clamps and fixes the wheel hub. Then, the output shaft of the rotary motor drives the gear to rotate, and the gear drives the gear ring, the rotary table and the mounting cylinder to rotate, thereby driving the wheel hub to rotate.

[0012] Preferably, the rotating frame is bolted to the outer wall of the operating table, and channels are opened on the upper outer walls of both sides of the rotating frame. The lifting plate is slidably installed in the two channels on both sides. Two limiting rods are fixed on the top outer wall of the lifting plate, and the two limiting rods pass through and are slidably installed on the top outer wall of the rotating frame.

[0013] Preferably, an installation plate is fixed on the bottom outer wall of the lifting plate, and the adjusting cylinder is connected to one side of the outer wall of the installation plate by bolts. The top of the installation frame abuts against the bottom outer wall of the lifting plate, and two connecting blocks are respectively snapped into the outer walls on both sides of the lifting plate. One end of the screw is connected to the inner wall on one side of the installation frame by a bearing, and the threaded block is slidably installed in the installation frame.

[0014] Preferably, two limiting plates are fixed on the top outer wall of the connecting frame, and the two limiting plates abut against the outer walls of the mounting frame on both sides respectively. The bottom end of the polishing motor output shaft is connected to the mounting shaft through a coupling, and the polishing wheel is connected to the bottom outer wall of the mounting shaft by bolts.

[0015] The above scheme involves rotating the polishing wheel by rotating the frame, making the polishing wheel parallel to the raised polishing surface of the hub. Then, the lifting cylinder lowers the polishing wheel so that it contacts the hub. The piston rod of the adjusting cylinder moves, causing the polishing wheel to move. Then, the lifting cylinder lowers the polishing wheel, allowing the polishing wheel to polish the flat section of the hub's polishing surface.

[0016] Preferably, an opening is provided on the upper outer wall of one side of the operating table, and one end of the collection box is fitted into the opening. Both the operating table and the rotating table have through holes on their top outer walls, and the box cover has a feed inlet on its top outer wall. The position of the feed inlet matches the position of the through hole.

[0017] The above method uses a fan to draw the dust generated during polishing into the mounting cylinder, and then into the collection box through the through hole and feed port. The filter screen filters the dust, causing it to accumulate in the collection box. The collection box can then be removed to clean the dust inside.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. The rotating frame drives the polishing wheel to rotate, making the polishing wheel parallel to the raised polishing surface of the wheel hub. Then, the lifting cylinder drives the polishing wheel to descend, bringing it into contact with the wheel hub. The adjusting cylinder piston rod moves, causing the polishing wheel to move. Then, the lifting cylinder drives the polishing wheel to descend, allowing the polishing wheel to polish the flat section of the wheel hub's polishing surface. The position and angle of the polishing wheel can be adjusted, enabling it to fully polish the wheel hub's polishing surface, thus improving its practicality.

[0020] 2. The fan operates, sucking the dust generated during polishing into the installation cylinder, and then through the through hole and feed port into the collection box. The filter screen filters the dust, causing it to accumulate in the collection box. The collection box can be pulled out to clean the dust inside. This method can collect the dust generated during polishing, preventing a large amount of dust from drifting into the external environment and improving environmental protection.

[0021] In summary, this utility model can adjust the position and angle of the polishing wheel, enabling it to fully polish the surface of the wheel hub, thus improving its practicality. It can also collect the dust generated during polishing, preventing a large amount of dust from drifting into the external environment, thereby improving its environmental friendliness.
