Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0026] This invention provides a washer bearing retainer assembly machine, such as... Figures 1 to 5As shown, the gasket and bearing retainer assembly machine includes a gasket feeding mechanism 1, a bearing feeding mechanism 2, a gasket retainer mechanism 3, a bearing retainer mechanism 4, and a pressing base 5. The gasket feeding mechanism 1 and the gasket retainer mechanism 3 are correspondingly arranged, and the bearing feeding mechanism 2 and the bearing retainer mechanism 4 are correspondingly arranged. The pressing base is located between the gasket retainer mechanism 3 and the bearing retainer mechanism 4. The pressing base 5 is used to fix the motor semi-finished product. The gasket feeding mechanism 1 is used to feed the gasket to the gasket retainer mechanism 3, and the gasket retainer mechanism 3 is used to move the gasket to the pressing base 5 and clamp the gasket onto the shaft of the motor semi-finished product. The bearing feeding mechanism 2 is used to feed the bearing to the bearing retainer mechanism 4, and the bearing retainer mechanism 4 is used to move the bearing to the pressing base 5 and clamp the bearing onto the shaft of the motor semi-finished product. The overall design is compact, which helps to quickly realize the retainer assembly operation of gaskets and bearings, improves assembly efficiency, and significantly reduces labor costs.

[0027] In this embodiment, the gasket feeding mechanism 1 includes an oscillating feeding plate 11 and a guiding channel 12. The oscillating feeding plate 11 has an annular feeding guide groove. One end of the guiding channel 12 communicates with the feeding guide groove, and the end of the guiding channel 12 away from the feeding guide groove is close to the gasket retaining ring mechanism 3. The end of the guiding channel 12 away from the feeding guide groove extends downward at an angle close to the gasket retaining ring mechanism 3, so that the gasket can gradually slide towards the material picking position of the gasket retaining ring mechanism 3, thereby realizing the gasket feeding operation.

[0028] It should be noted that in this embodiment, the structural layout of the bearing feeding mechanism 2 is the same as that of the gasket feeding mechanism 1. In actual application, the description of the gasket feeding mechanism 1 mentioned above can be referred to.

[0029] In this embodiment, the gasket retaining mechanism 3 includes an inclined slide cylinder 31. The end of the slide cylinder 31 near the pressing base 5 faces upward. When a semi-finished motor is placed on the pressing base 5, the height of the slide cylinder 31 should be higher than the semi-finished motor to achieve the corresponding retaining operation described below. Specifically, the sliding end of the slide cylinder 31 faces downward, and the sliding end of the slide cylinder 31 is provided with a support block 32 parallel to the slide cylinder 31 to drive the support block 32 to move at an incline. The end of the support block 32 near the pressing base 5 is connected to a retaining block 34 via a first spring 33. The retaining block 34 is inclined and its inclination direction is opposite to that of the support block 32. The retaining block 34 is used to receive the gasket when the material arrives and to allow the gasket to be removed during retaining. A push block 35 parallel to the support block 32 is slidably provided on the lower surface of the support block 32. An inverted L-shaped support column 36 is also provided at the end of the support block 32 away from the first spring 33. The push block 35 is connected to the inverted L-shaped support column 36 through a second spring 37, which provides the push block 35 with compression space. In the initial state, the retaining ring block 34 abuts against the upper surface of the push block 35 and is held on the same inclined plane as the support block 32. The end faces of the push block 35 and the retaining ring block 34 near the press base 5 are flush with each other.

[0030] It should be noted that in this embodiment, the tilt angles of the slide cylinder 31, support block 32, retaining ring block 34 and abutment block 35 are all designed to enable the gasket retaining ring to be achieved through mutual cooperation. In specific implementation, the design and selection can be made according to the actual application requirements. This embodiment does not impose any specific limitations.

[0031] The support block 32 and the abutment block 35 are connected by a sliding groove and a slider to form a sliding connection structure. The slider is adapted to the sliding groove, such as a dovetail groove.

[0032] Furthermore, the retaining ring block 34 has a perforated groove 340 extending through its upper and lower surfaces. A gap 341 communicating with the perforated groove 340 is formed on the side wall of the retaining ring block 34 near the material guide channel 12 to allow the gasket to slide in. The gap 341 extends inward along the inner circumferential side wall of the perforated groove 340, forming a retaining groove for the gasket to be inserted and supported. An opening communicating with the perforated groove 340 is formed on the side wall of the retaining ring block 34 near the pressing base 5 to allow the gasket to be removed. A receiving groove is also formed on the side wall of the retaining ring block 34 near the pressing base 5, located on the side of the opening and communicating with it. A limiting block 38 for opening or closing the opening is provided in the receiving groove. In this embodiment, the limiting block 38 is elastically connected to the receiving groove by a torsion spring.

[0033] During the clamping process, the slide cylinder 31 drives the support block 32 to move towards the location of the motor semi-finished product. The support block 32 then moves the abutment block 35 along with it. The abutment block 35 first abuts against the motor semi-finished product. During this process, as the support block 32 continues to move, the clamping block 34 gradually moves out to above the shaft of the motor semi-finished product. The clamping block 34 returns to its tilted state, and the slot 340 fits onto the shaft of the motor semi-finished product, causing the shim to slide down and fit onto the shaft of the motor semi-finished product. Subsequently, the slide cylinder 31 drives the support block 32 to move away from the motor semi-finished product. The clamping block 34 applies a certain pressure to the shim to ensure stable fitting. When the clamping block 34 moves a certain distance, the shaft of the motor semi-finished product abuts against the limiting block 38, causing the limiting block 38 to open, and the clamping block 34 smoothly exits, thus completing one shim clamping operation. The bearing is a ball bearing; the shim is a pebbly fork shim.

[0034] It should be noted that in this embodiment, the structural layout of the bearing retaining mechanism 4 is the same as that of the gasket retaining mechanism 3. In actual application, the description of the gasket retaining mechanism 3 described above can be used. In other embodiments, the bearing retaining mechanism 4 can also use any other suitable mechanism to perform the bearing retaining operation. For example, the bearing can be moved above the shaft of the motor semi-finished product by a horizontally set translation mechanism. After the bearing is aligned with the shaft of the motor semi-finished product, the translation mechanism can be driven by a lifting and pressing mechanism to press down as a whole to lock the bearing into place.

[0035] In this embodiment, the press-fit base 5 includes a base plate 51 and a U-shaped support plate 52. The U-shaped support plate 52 has its opening facing downwards and is disposed on the base plate 51. The upper surface of the U-shaped support plate 52 is provided with a press-fit positioning component 6 for accommodating the semi-finished motor. The press-fit positioning component 6 can be any suitable component with a buffer mechanism. This embodiment does not impose specific limitations and should be based on actual application. Specifically, an enclosing space is formed between the base plate 51 and the U-shaped support plate 52. The base plate 51 is also provided with a limiting shaft located within the enclosing space, and the limiting shaft corresponds to the press-fit positioning component 6. Correspondingly, the gasket bearing retainer assembly machine also includes a pressing shell mechanism 7. The pressing shell mechanism 7 is located above the press-fit base 5 and is used to press the outer shell onto the semi-finished motor after the gasket and bearing retainer are in place. The pressing shell mechanism 7 may include pressing components such as a pressing cylinder. For specific details, refer to the press-fit mechanism in the prior art.
