Technical Field

[0001] The utility model belongs to the technical field of bearing bush processing, and more specifically, relates to a positioning device for a bearing bush. Background Art

[0002] The bearing bush is the part that contacts the journal of the sliding bearing, and its shape is a semi-cylindrical surface in the shape of a tile. In the chamfering process of the bearing bush, the bearing bush needs to be loaded into the installation station on the positioning turntable through a limiting plate, and then the two ends of the bearing bush are chamfered by chamfering devices arranged on the two end faces of the positioning turntable relatively.

[0003] For the existing positioning device of the bearing bush, after the positioning turntable is connected to the limiting plate, in order to ensure the stability of the bearing bush during the processing, it is also necessary to rely on external equipment to limit the limiting plate, which also causes the existing positioning device to be unable to independently realize the positioning of the bearing bush, resulting in the limitation of its use range. And because the existing positioning device of the bearing bush is of a split design, the operation is relatively complex and time-consuming, and it is difficult to meet the requirements for efficient processing of the bearing bush.

[0005] To achieve the above purpose, the utility model provides a positioning device for a bearing bush, which is used for positioning the bearing bush to be chamfered;

[0006] The positioning device includes a positioning turntable, a driving unit for driving the positioning turntable to rotate, and a limiting plate;

It should be understood that other ways belonging to a general inventive concept of the present utility model can be used to implement the technical solution of the present utility model, and should not be limited by the exemplary embodiments described. Based on one or more embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0037] Referring to Figures 1-3 , an embodiment of the present utility model provides a positioning device for a bearing bush, which is used to position the bearing bush to be chamfered;

[0038] The positioning device includes a positioning turntable 1, a driving unit 2 for driving the positioning turntable 1 to rotate, and a limit plate 3;

[0039] On the positioning turntable 1, at least one installation station 4 for loading bearing bushes is provided along its circumferential direction. On both sides of the installation station 4, support seats 5 are oppositely arranged. On the support seats 5, rotating rods 6 are provided. Along the direction perpendicular to the rotating rods 6, limiting rods 7 are provided.

[0040] The limiting plates 3 are correspondingly arranged in each of the at least one installation station 4. The limiting rods 7 are used to limit the limiting plates 3.

[0041] In one embodiment, a driving connection port 8 is provided in the positioning turntable 1. The transmission end of the driving unit 2 is connected to the positioning turntable 1 through the driving connection port 8.

[0042] In a specific embodiment, the driving unit 2 is a motor, and the driving end of the motor is electrically connected to an external control device.

[0043] Specifically, the external control device can supply power to and drive the motor according to the requirements of chamfering processing.

[0044] In a specific embodiment, six installation stations 4 for loading bearing bushes are provided along the circumferential direction of the positioning turntable 1.

[0045] In a specific embodiment, each installation station 4 is in a semi-circular arc shape.

[0046] In a specific embodiment, one end of the limiting plate 3 facing the installation station 4 is arranged in an arc-shaped installation groove 31. The installation groove is used for installing the bearing bush.

[0047] In one embodiment, on both sides of the open end of the installation station 4, grooves 9 for installing the limiting plates 3 are symmetrically arranged.

[0048] In one embodiment, on one end of the limiting plate 3 facing the installation station 4, connecting rods 10 adapted to the grooves 9 are symmetrically arranged.

[0049] In one embodiment, on one end of the limiting plate 3 facing the rotating rod 6, a limiting groove 32 matching the limiting rod 7 is provided.

[0050] In a specific embodiment, on one end of the limiting plate 3 facing the rotating rod 6, four limiting grooves 32 matching the limiting rod 7 are provided.

[0051] In one embodiment, the opening directions of the limiting grooves at both ends of the limiting plate 3 are opposite. So that the limiting rod can limit the limiting plate from opposite directions, effectively preventing the limiting plate from shifting during the chamfering process of the bearing bush, thereby improving the stability of the bearing bush.

[0052] When the positioning device of the present utility model is in use, it is placed between the relatively placed chamfering devices, and the chamfering drill bits of the chamfering devices correspond to the installation stations. First, the operator inserts the connecting rod of the limiting plate into the groove, then splices the open ends of the two bearing bushes to form a bearing sleeve, and places it between the installation station and the installation groove. Then, the rotating rod is rotated so that the rotating rod drives the limiting rods to move into the limiting grooves one by one. Next, the driving unit and the chamfering device are started through an external control device to chamfer the bearing bushes. At the same time, the operator can recycle the chamfered bearing bushes on the side far from the chamfering device and place the non-chamfered bearing bushes in the installation station until all the bearing bushes are chamfered.

[0053] The positioning device for the bearing bush proposed by the present utility model is provided with at least one installation station for loading the bearing bush along its circumferential direction on the positioning turntable. Support seats are oppositely arranged on both sides of the installation station. A rotating rod is arranged on the support seat, and a limiting rod is arranged on the rotating rod along a direction perpendicular to it. The limiting plate is correspondingly arranged in each of the at least one installation station, so that the limiting rod can limit the limiting plate, thereby playing a role in positioning the bearing bush.

[0054] Therefore, compared with the existing positioning devices for bearing bushes, the positioning device of the present utility model can realize the positioning of the bearing bush only through the limitation of its own structure, expands the application range of the positioning device, and can meet the requirements for efficient processing of the bearing bush.

[0055] Although one or more embodiments of the present utility model have been described above, those of ordinary skill in the art should know that the present utility model can be implemented in any other form without departing from its gist and scope. Therefore, the embodiments described above are illustrative rather than restrictive. Many modifications and substitutions are obvious to those of ordinary skill in the art in the technical field without departing from the spirit and scope of the present utility model as defined by the appended claims.
