[0043] Referring Figures 1-3 , an embodiment of the present utility model provides a polishing device for a bearing bush, including a control box 1, a polishing mechanism and a bearing bush clamping mechanism which are arranged on the control box 1 and electrically connected to the control box 1;

[0044] The polishing mechanism includes an X-axis adjustment component, a Y-axis adjustment component and a polishing component. The X-axis adjustment component is connected to the Y-axis adjustment component and is used to drive the Y-axis adjustment component to move along the X-axis. The Y-axis adjustment component is connected to the polishing component and is used to drive the polishing component to move along the Y-axis. The polishing component includes a connection bracket 2 and a polishing head 3. The connection bracket 2 is configured to be able to drive the polishing head 3 to perform a reciprocating circumferential movement along the bearing bush 4, and the polishing head 3 is configured to be able to rotate axially relative to the connection bracket 2;

[0045] The bearing bush clamping mechanism includes a first arc-shaped clamping rod 5 and a second arc-shaped clamping rod 6 that matches the first arc-shaped clamping rod 5. The second arc-shaped clamping rod 6 is configured to be able to move relative to the first arc-shaped clamping rod 5 along a direction parallel to the X-axis for clamping or releasing the bearing bush 4.

[0046] In a specific embodiment, the polishing device further includes a host computer, which is electrically connected to the control box 1 for controlling the polishing mechanism and the bearing bush clamping mechanism (not shown in the figure).

[0047] In an embodiment, the X-axis adjustment component includes a first sliding table 7 and a first guide rail 8 arranged along the X-axis. The first sliding table 7 is configured to be able to move along the first guide rail 8, and the Y-axis adjustment component is connected to the first sliding table 7.

[0048] In an embodiment, the Y-axis adjustment component includes a second sliding table 9 and a second guide rail 10 arranged along the Y-axis. The second sliding table 9 is configured to be able to move along the second guide rail 10, and the first driving unit and the connection bracket are respectively connected to both sides of the second sliding table.

[0049] Specifically, the settings of the first sliding table, the first guide rail, the second sliding table and the second guide rail can drive the polishing component to move relative to the bearing bush clamping mechanism along the X-axis and the Y-axis to switch the polishing working surface during the polishing process of the bearing bush, so as to realize the polishing treatment of the outer side and the inner side of the bearing bush. Moreover, the X-axis adjustment component and the Y-axis adjustment component have a simple structure and can be quickly controlled by the host computer, thereby greatly improving the efficiency of polishing the bearing bush.

[0050] In one embodiment, the polishing assembly further includes a first driving unit 11, a connecting shaft 12, and a second driving unit 13. The first driving unit 11 is connected to one end of the connecting bracket 2 and is used to drive the connecting bracket 2 to rotate axially. The connecting shaft 12 is connected to the other end of the connecting bracket 2 and can drive the polishing head 3 to rotate axially relative to the connecting bracket 2 through the second driving unit 13.

[0051] In a specific embodiment, the shape of the connecting bracket 2 is L-shaped.

[0052] In a specific embodiment, the shape of the polishing head 3 is cylindrical.

[0053] In a specific embodiment, both the first driving unit 11 and the second driving unit 13 are motors.

[0054] Specifically, when polishing the bearing bush, first, the first driving unit drives the connecting bracket to rotate axially. The rotating connecting bracket drives the polishing head to perform a reciprocating circumferential motion along the outer or inner side of the bearing bush. At the same time, the second driving unit drives the connecting shaft to rotate axially relative to the connecting bracket, thereby driving the polishing head to rotate axially to achieve the polishing of the outer or inner side of the bearing bush.

[0055] In a specific embodiment, the rotational speed of the transmission end of the first driving unit 11 is less than the rotational speed of the transmission end of the second driving unit 13. This enables the polishing head to fully polish the double-sided wall of the bearing bush to ensure the effect of the polishing treatment of the bearing bush.

[0056] In one embodiment, the bearing bush clamping mechanism further includes a fixed seat 14, a movable seat 15, and an electric cylinder 16. The first arc-shaped clamping rod 5 is arranged on the fixed seat 14, and the movable seat 15 can drive the second arc-shaped clamping rod 6 to move relative to the first arc-shaped clamping rod 5 along the direction parallel to the X-axis through the electric cylinder 16 to achieve the clamping or release of the bearing bush.

[0057] In a specific embodiment, the bearing bush clamping mechanism further includes a base 17 for supporting the fixed seat 14 and the electric cylinder 16.

[0058] In a specific embodiment, the widths of both the first arc-shaped clamping rod 5 and the second arc-shaped clamping rod 6 are smaller than the wall thickness of the bearing bush 4 to avoid the first arc-shaped clamping rod and the second arc-shaped clamping rod from blocking the bearing bush and affecting the polishing treatment of the bearing bush.

[0059] When the polishing equipment of the present utility model is in use, first, the bearing shell can be placed on the fixed seat by an external robotic arm grasping mechanism or manually by an operator, and one side of the bearing shell is made to closely adhere to the first arc-shaped clamping rod. Then, the electric cylinder is started through the upper computer, so that the electric cylinder drives the movable seat to drive the second arc-shaped clamping rod to move towards the first arc-shaped clamping rod until the bearing shell is tightly clamped between the first arc-shaped clamping rod and the second arc-shaped clamping rod. Then, the X-axis adjustment component and the Y-axis adjustment component are started through the upper computer to move the polishing head to contact the inner wall or the outer wall of the bearing shell. Next, the first driving unit and the second driving unit are started, so that while the polishing head makes a reciprocating circumferential movement along the wall of the bearing shell, the wall of the bearing shell is polished by axial rotation. Finally, after both sides of the bearing shell are polished, the electric cylinder can be driven again to drive the second arc-shaped clamping rod to retract, and then the bearing shell is removed from the fixed seat.

[0060] For the polishing equipment of the bearing shell of the present utility model, on the one hand, by providing an X-axis adjustment component, a Y-axis adjustment component and a polishing component, the X-axis adjustment component is connected to the Y-axis adjustment component and is used to drive the Y-axis adjustment component to move along the X-axis. The Y-axis adjustment component is connected to the polishing component and is used to drive the polishing component to move along the Y-axis. The polishing component includes a connecting bracket and a polishing head. The connecting bracket is configured to be able to drive the polishing head to make a reciprocating circumferential movement along the bearing shell, and the polishing head is configured to be able to axially rotate relative to the connecting bracket. On the other hand, by providing a first arc-shaped clamping rod and a second arc-shaped clamping rod matching the first arc-shaped clamping rod, the second arc-shaped clamping rod is configured to be able to move relative to the first arc-shaped clamping rod along a direction parallel to the X-axis for clamping or releasing the bearing shell.

[0061] Therefore, compared with the existing polishing equipment for bearing shells, the polishing equipment of the present utility model can adjust the polishing head in the X-axis direction and the Y-axis direction, so that the polishing head can quickly contact both sides of the bearing shell. At the same time, the polishing head has the functions of reciprocating circumferential movement and axial rotation, so that it can accurately contact both sides of the bearing shell to achieve rapid and accurate polishing of the bearing shell.

[0062] At the same time, the first arc-shaped clamping rod and the second arc-shaped clamping rod of the present utility model can improve the stability of the bearing shell during the polishing process and facilitate the clamping and releasing of the bearing shell.

[0063] In summary, using the polishing equipment of the present utility model can effectively improve the polishing efficiency of the bearing shell and is more practical.
