[0002] The bearing shell is the part that contacts the journal and is a semi-cylindrical surface in the shape of a tile. It is very smooth and is generally made of wear-resistant materials such as bronze and anti-friction alloy. In special cases, it can be made of wood, engineering plastics or rubber.

[0003] During the machining process, a boring cutter is required to fine-machine the inner wall of a bearing to ensure its smoothness. However, existing fine-boring devices lack a good structure to limit the position of the bearing, resulting in poor stability during machining, which affects the machining quality of the bearing. In addition, the existing fine-boring device needs to be shut down after running for a period of time to collect the processed bearing. This problem also reduces the efficiency of the bearing fine-boring process, making the existing fine-boring device still have some limitations when used and cannot meet the needs of long-term fine-boring of bearings.

[0044] Reference Figure 1-3 The embodiment of the present utility model provides a precision boring device for bearing bushing processing, comprising:

[0045] Base plate 1;

[0046] The fine boring mechanism includes a control box 2, a boring tool 3 and a boring tool drive assembly. The control box 2 is arranged on the base plate 1, and the boring tool 3 is connected to the control box 2 through the boring tool drive assembly.

[0047] The bearing clamping mechanism is arranged below the boring tool 3, and includes a mounting frame 4, a driving member 5 for driving the mounting frame 4 to perform axial movement, and a limit assembly. A plurality of limit plates 6 are evenly distributed along the circumference of the mounting frame 4. The limit assembly includes a connecting rod 7 symmetrically arranged on each of the plurality of limit plates 6, and a stop block 8 is sleeved on the connecting rod 7. The stop block 8 is used to fix the bearing 9 in each limit plate 6.

[0048] In one embodiment, the boring tool drive assembly includes a second motor 10, a screw rod 11, a movable plate 12 having a connecting end 121, and a third motor 13. The movable plate 12 can slide up and down on the screw rod 11 through the second motor 10. The boring tool 3 is connected to the connecting end 121 and can rotate under the drive of the third motor 13.

[0049] Specifically, the movable block is threadedly connected to the screw rod, so that when the screw rod rotates under the drive of the second motor, the movable block can interact with the screw rod to drive the boring tool to move up and down, so that the boring tool can contact the bearing shell in each limit plate and perform precision boring on its inner wall under the drive of the third motor.

[0050] In one embodiment, the bearing clamping mechanism further includes a first support frame 14 and a second support frame 15 both disposed on the base plate 1 , and the mounting frame 4 is mounted between the first support frame 14 and the second support frame 15 via a driving member 5 .

[0051] In a specific embodiment, the first support frame 14 and the second support frame 15 are both triangular in shape.

[0052] In a specific embodiment, the driving member 5 is a first motor, and the mounting bracket 4 is sleeved on the driving end of the first motor. The first motor can drive the mounting bracket to rotate, so as to sequentially position each limit plate under the boring tool, thereby facilitating the loading and unloading of the bearing shell.

[0053] In a specific embodiment, the control box 2 is provided with a control panel 21 for controlling the first motor, the second motor 10, and the third motor 13. Specifically, the control box has a control unit for controlling the operation of the first motor, the second motor, and the third motor, and the control panel is electrically connected to the control unit to achieve precise control of the first motor, the second motor, and the third motor.

[0054] In one embodiment, a pressing block 16 is sleeved on the stopper 8 , and the pressing block 16 is threadedly connected to the connecting rod 7 to limit the position of the stopper 8 .

[0055] In a specific embodiment, the shape of the stopper 8 is triangular and can limit the outer edge of the bearing shell to fix the bearing shell in the limiting plate.

[0056] When the precision boring device of the present invention is in use, first, the bearing can be placed one by one in each limit plate manually, and the stop block can be rotated so that the stop block limits the outer edge of the bearing. Then, the first motor, the second motor and the third motor can be started in sequence through the control panel. Driven by the first motor, the mounting plate moves the bearing in each limit plate to the bottom of the boring tool in sequence. Driven by the second motor, the boring tool moves downward until it contacts the inner wall of the bearing and rotates at high speed driven by the first motor to perform precision boring on the bearing. During the processing, the processed bearing can be taken off the mounting frame manually, and then the unprocessed bearing can be placed on each limit plate until all the bearings are processed.

[0057] The precision boring device for bearing processing proposed by the present invention can simultaneously limit the position of several bearings by using a mounting frame arranged below the boring cutter and a plurality of limit plates evenly distributed on the mounting frame along the circumference thereof, and fix the bearings by means of a stop block to ensure the stability of the bearings during the precision boring process, thereby improving the processing quality of the bearings. Furthermore, by setting a driving member, the driving member can drive the mounting frame to move axially, so that the several bearings can be rotated to the bottom of the boring cutter in sequence through the axial movement of the mounting frame, so as to be processed by the boring cutter, and during this process, the bearings can be manually loaded or unloaded into the limit blocks other than the limit blocks with the bearing being processed, thereby completing the loading and unloading of the bearings without stopping the precision boring device, thereby effectively improving the processing efficiency of the bearings.

[0058] Therefore, compared with the existing precision boring device, the precision boring device of the utility model can limit several bearing shells at the same time, thereby realizing high-efficiency processing of the bearing shells, and thus can meet the demand for long-term processing of the bearing shells.

Therefore, the embodiments described above are illustrative and not restrictive, and many modifications and substitutions will be apparent to those skilled in the art without departing from the spirit and scope of the present invention as defined in the appended claims.
