[0006] The purpose and effectiveness of this utility model's quick mold change device for automotive wheel hub bearing assembly lines are achieved through the following specific technical means:

[0007] A quick mold-changing device for an automotive wheel hub bearing assembly line includes a bearing assembly machine body, a press-fit cylinder, a press-fit support platform, a mold-changing drive turntable, mold heads, a mold-changing drive motor, a press-fit protection mechanism, and a mold-changing drive mechanism. The press-fit cylinder is fixedly connected to the upper front end of the bearing assembly machine body. The press-fit support platform is fixedly connected to the lower front end of the bearing assembly machine body. The mold-changing drive turntable is rotatably connected to the upper front end of the press-fit support platform.

The mold-changing drive motor is fixedly connected to the inner side of the bearing assembly machine body. The press-fit protection mechanism is located above the press-fit support platform. The mold-changing drive mechanism is located below the press-fit support platform.

[0008] Furthermore, the press-fitting protection mechanism includes: a protective limiting groove, a protective shield, and an operating rod; the protective limiting groove is a semi-circular annular groove structure, and the protective limiting groove is opened above the press-fitting support platform; the protective shield is slidably connected to the upper interior of the protective limiting groove, and the protective shield is set on the outer side of the mold changing drive turntable; the operating rod is fixedly connected to the front end of the protective shield.

[0009] Furthermore, the press-fitting protection mechanism also includes a protective connecting spring; the protective connecting spring is fixedly connected to the upper end of the press-fitting support platform, and the upper end of the protective connecting spring is fixedly connected to the operating rod.

[0010] Furthermore, the mold changing drive mechanism includes a mold changing drive worm and a mold changing drive worm wheel; the mold changing drive worm is rotatably connected to the lower part of the pressing support platform, and the mold changing drive worm is coaxially and fixedly connected to the rotating shaft of the mold changing drive motor; the mold changing drive worm wheel is rotatably connected to the lower part of the pressing support platform, and the mold changing drive worm wheel meshes with the mold changing drive worm.

[0011] Furthermore, the mold changing drive mechanism also includes a mold changing drive pin and a mold changing drive grooved wheel; the mold changing drive pin is coaxially and fixedly connected to the upper end of the mold changing drive worm gear; the mold changing drive grooved wheel is coaxially and fixedly connected to the lower end of the mold changing drive turntable, and the mold changing drive grooved wheel and the mold changing drive pin together form a grooved wheel structure.

[0012] Furthermore, the mold changing drive mechanism also includes: a mold changing limiting component, a mold changing limiting groove, and a mold changing ejector rod; the mold changing limiting component is a cylindrical structure, fixedly connected to the upper part of the pressing support platform, and positioned below the mold changing drive turntable; the mold changing limiting groove is formed on the outer periphery of the mold changing limiting component, and is a convex groove structure; multiple sets of mold changing ejector rods are provided, one end of each set of ejector rods is fixedly connected to the lower inner side of the mold head component by bolts, and the other end of each set of ejector rods is slidably connected to the inner side of the mold changing limiting groove.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention, through the setting of a press-fitting protective mechanism, allows the worker to first move the operating lever downwards. The downward movement of the operating lever causes the protective shield to move downwards as well. Once the protective shield moves downwards, it no longer obstructs the mold-changing drive turntable, allowing the worker to retrieve the bearing. This increases the worker's operating steps, prevents the worker's hands from directly entering the press-fitting area, thus protecting the worker and improving the overall safety of the device.

[0015] This invention, through the setting of a mold-changing drive mechanism, automatically changes the mold head by turning on the mold-changing drive motor. The rotation of the motor's shaft drives the mold-changing drive worm gear, which in turn drives the mold-changing drive worm wheel. The worm wheel then drives the mold-changing drive pin, which in turn drives the mold-changing drive grooved wheel. This rotation of the grooved wheel drives the mold-changing drive turntable, which in turn drives the mold head component. Once the appropriate mold head component is rotated to the position below the pressing cylinder, the mold-changing drive motor is turned off. This achieves automatic mold head component replacement, avoiding manual operation by workers, improving the efficiency of mold head component replacement, and increasing the assembly efficiency of automotive wheel hub bearings.
