[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-5 As shown, a feeding device for polishing automotive bushings includes a main bushing 2 and a machine base 1 with a loading platform 4 sliding vertically on its top. A cylindrical platform 12 fixedly mounted on the top of the machine base 1 and a loading channel 42 opened in the loading platform 4 are arranged coaxially. The loading platform 4 has movable cavities 41 arranged in a circular array, and a limiting rod 8 with one end located in the loading channel 42 is hinged in the movable cavity 41. The main bushing 2 is fed onto the cylindrical platform 12 along the loading channel 42 on the loading platform 4, thereby achieving fast and precise feeding. By driving multiple limiting rods 8 to rotate, the feeding of the main bushing 2 in the loading channel 42 can be controlled, which facilitates the control of feeding when needed, reduces the tedious operation of manual feeding, and improves feeding efficiency.

[0027] As a further technical solution provided by this utility model, an extrusion rod 82 is slidably arranged in the active cavity 41, and the first end of the extrusion rod 82 is movably arranged on the outer wall of the main shaft sleeve 2 in the feed channel 42.

[0028] Specifically, by sliding and pressing the main shaft sleeve 2 through the extrusion rod 82, when the limit rod 8 flips to feed the bottom main shaft sleeve 2, the extrusion rod 82 fixes the other main shaft sleeve 2 adjacent to the bottom main shaft sleeve 2, thus avoiding the problem of uncontrollable continuous feeding of the main shaft sleeve 2.

[0029] Furthermore, a lever plate 5 is symmetrically fixedly installed on the top of the machine base 1. The side plate 52 on the lever plate 5 is movably mounted on the inclined surface 83 at the second end of the extrusion rod 82. A return spring 84 is fixedly installed between the extrusion rod 82 and the inner wall of the movable cavity 41.

[0030] Specifically, when the unloading platform 4 moves down, the lever 5 moves up relative to the unloading platform 4. At this time, the side plate 52 on the lever 5 presses the inclined surface 83 to make the pressing rod 82 slide and push the other main shaft sleeve 2 of the adjacent bottom main shaft sleeve 2. At this time, the return spring 84 stores force, and then the limit rod 8 flips to allow the bottom main shaft sleeve 2 to be loaded. After processing, the limit rod 8 resets. Then, when the unloading platform 4 moves up, the return spring 84 releases the stored force to release the pressing rod 82 from pushing and fixing the main shaft sleeve 2. At this time, the main shaft sleeve 2 falls onto the limit rod 8.

[0031] Furthermore, the long plate 51 on the lever 5 is movably positioned at one end of the limiting rod 8 relative to the feed channel 42, and the limiting rod 8 is equipped with a torsion spring 81.

[0032] Specifically, the torsion spring 81 is sleeved on the hinge shaft of the limiting rod 8, and the two ends of the torsion spring 81 are respectively fixedly installed on the inner wall of the movable cavity 41 and the limiting rod 8. As the unloading platform 4 moves down, the side plate 52 on the lever 5 first presses the inclined surface 83 to make the pressing rod 82 slide and push the other main shaft sleeve 2 of the adjacent bottom main shaft sleeve 2. The torsion spring 81 and the return spring 84 store force respectively. Then, as the unloading platform 4 continues to move down, the long plate 51 moves the limiting rod 8 to flip. At this time, the bottommost main shaft sleeve 2 is released from restriction and can be loaded. Then, when the unloading platform 4 moves up, the torsion spring 81 drives the limiting rod 8 to reset and block again. Then, when the side plate 52 is separated from the pressing rod 82, the return spring 84 releases the stored force so that the pressing rod 82 releases the pushing and fixing of the main shaft sleeve 2. At this time, the main shaft sleeve 2 falls onto the limiting rod 8.

[0033] Furthermore, a grinding ring 73 is rotatably arranged at the bottom of the unloading platform 4 and is coaxially arranged with the unloading channel 42. A grinding pad 74 is fixedly installed on the inner wall of the grinding ring 73. A grinding motor 7 is fixedly installed inside the unloading platform 4. The main gear 71 fixedly installed at the output end of the grinding motor 7 meshes with the auxiliary gear 72 fixedly installed on the outer wall of the grinding ring 73.

[0034] Specifically, when the material platform 4 moves down and the main shaft sleeve 2 disengages from the flipping limit rod 8, the main shaft sleeve 2 falls onto the cylindrical platform 12. Then, the grinding ring 73 surrounds the main shaft sleeve 2. After fixing the main shaft sleeve 2, the grinding motor 7 is started. At this time, the main gear 71 and the auxiliary gear 72 mesh to drive the grinding ring 73 to rotate, and work with the grinding pad 74 to grind and polish the outer wall of the main shaft sleeve 2.

[0035] Furthermore, a rubber guide ring 17 is fixedly installed on the top of the cylindrical platform 12, and the first airbag 6 fixedly installed on the rubber guide ring 17 is connected to the air cavity 14 opened inside the cylindrical platform 12.

[0036] Specifically, the rubber guide ring 17 is used to guide the main sleeve 2 as it falls, while the first airbag 6 inflates on the inner wall of the main sleeve 2 to fix the main sleeve 2 to a certain extent.

[0037] Furthermore, a base column 13 connected to the air chamber 14 is fixedly installed inside the machine 1. Multiple second airbags 16 fixedly installed on the outer wall of the base column 13 are connected to the air chamber 14 through air holes 15 opened on the base column 13. The insertion tube 32 slidably installed inside the machine 1 moves on the second airbags 16.

[0038] Specifically, by driving the insertion tube 32 to move on the second airbag 16 to compress the second airbag 16, the gas in the second airbag 16 enters the first airbag 6 along the air chamber 14, thereby driving the first airbag 6 to expand on the inner wall of the main sleeve 2 and fixing the main sleeve 2 to a certain extent.

[0039] Furthermore, an electric push rod 3 is fixedly installed inside the machine base 1, and the bracket 31 and the insertion tube 32 are fixedly connected at the output end of the electric push rod 3.

[0040] Specifically, by using the electric push rod 3 to drive the bracket 31 to move downward, the bracket 31 drives the insertion tube 32 to move and press against the second airbag 16.

[0041] Furthermore, the guide rod 33 fixedly installed at the bottom of the unloading platform 4 slides within the guide tube 11 fixedly installed at the top of the machine base 1, and the guide rod 33 is fixedly installed on the bracket 31 respectively.

[0042] Specifically, the electric push rod 3 drives the bracket 31 to move down, so that the unloading platform 4 moves down synchronously and approaches the machine base 1. Then, when the main shaft sleeve 2 is disengaged from the flipped limit rod 8 to feed the material, the insertion tube 32 begins to move on the second air bag 16 to squeeze the second air bag 16 and drive the first air bag 6 to expand on the inner wall of the main shaft sleeve 2, thereby fixing the main shaft sleeve 2 to a certain extent.

[0043] Furthermore, the hopper 43 and the discharge channel 42, which are fixedly installed on the top of the discharge platform 4, are interconnected, and the first end of the extrusion rod 82 is fixedly installed with an anti-slip rubber pad 85.

[0044] Specifically, the hopper 43 facilitates material storage, and the anti-slip rubber pad 85 enhances the friction between the extrusion rod 82 and the main shaft sleeve 2.

[0045] Working principle: The electric push rod 3 drives the bracket 31 to move downward, so that the unloading platform 4 moves downward and approaches the machine base 1. Then, the side plate 52 on the deflector plate 5 first squeezes the inclined surface 83, so that the extrusion rod 82 slides and pushes the other main shaft sleeve 2 of the adjacent bottom main shaft sleeve 2. The torsion spring 81 and the return spring 84 store force respectively. Then, as the unloading platform 4 continues to move downward, the long plate 51 moves the limit rod 8 to flip. At this time, the main shaft sleeve 2 is disengaged from the flipped limit rod 8. Then, as the electric push rod 3 continues to pull the bracket 31 downward, the insertion tube 32 begins to move on the second air bag 16 to squeeze the second air bag 16 and drive the first air bag 6 to expand on the inner wall of the main shaft sleeve 2, thus fixing the main shaft sleeve 2 to a certain extent. Then, the grinding ring 73 surrounds the main shaft sleeve 2. By starting the grinding motor 7, the main gear 71 and the auxiliary gear 72 are meshed to drive the grinding ring 73 to rotate, which works with the grinding pad 74 to grind and polish the outer wall of the main shaft sleeve 2.

[0046] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
