[0055] The overall operation process of the automatic needle-installing device for a one-way bearing of the present invention is as follows:

[0056] The steps for stitching are as follows:

[0057] The roller needle to be installed is dropped into the needle loading device through the needle adding lower cover, the driving motor rotates to drive the flange to rotate, the flange drives the turntable to rotate, and the turntable, the clockwise cylinder and the disturbance rod rotate to bring the irregular roller needle into multiple vertical grooves on the outer cylindrical surface of the clockwise cylinder to achieve the needle loading step.

[0058] The steps for needle installation are as follows:

[0059] The needle roller falls into the needle guide tube through the hole in each groove, and a through hole with the same number as the one-way bearing needle rollers is provided above the needle loading body. The needle roller falls into the needle loading body through the needle guide tube, ready for needle loading; the pushing device pushes the outer ring of the bearing into the groove of the outer ring translation plate, and the outer ring of the bearing is restricted between the groove of the outer ring translation plate and the slide baffle after translation; the longitudinal cylinder pushes the outer ring translation plate to move longitudinally along the longitudinal linear guide rail assembly, and brings the outer ring of the bearing to the bottom of the positioning sleeve and onto the rotary lifting device. The rotary lifting device pushes upward to fix the outer ring of the bearing in the positioning sleeve. After the position is fixed, the telescopic rod of the needle placing cylinder moves forward, and drives the outer ring to rotate around the cylindrical surface of the needle loading body through the connecting plate and the column pin, and the spring pin is released. At this time, the needle roller falls into the outer ring of the bearing by its own gravity, and the needle loading step is realized.

[0060] The material transfer steps are as follows:

[0061] After the needle is loaded, the telescopic rod of the needle placing cylinder retracts, driving the outer ring to rotate outside the cylindrical surface of the needle loading body, compressing the spring pin and locking the upper roller needle; the rotary lifting device falls back, and the outer ring of the bearing with the needle loaded falls into the groove on the outer ring translation plate, and the transverse cylinder drives the transverse slide and the outer ring translation plate to move transversely along the transverse linear guide assembly to the position of the material tray, and the outer ring of the bearing is placed on the material tray to complete the needle loading.

[0062] The display and control system realizes the functions of parameter setting, needle loading statistics, manual-automatic state conversion setting, etc. during the needle loading process through the display touch screen, and realizes the cylinder sequential action, material shortage shutdown, data statistics, etc. through parameter and internal PLC program control. At the same time, the fixed slide is provided with a proximity sensor for counting and stopping needle loading when there is no material. The equipment involved in the present invention can realize the automatic material transfer, automatic needle loading, and automatic needle loading of the outer ring of the one-way bearing at the same time, and has the functions of data statistics, material shortage shutdown, cylinder action parameter setting, automatic and manual mode switching, etc. The equipment can also adjust the front and rear positions of the slide baffle and the outer ring translation plate by replacing the needle guide tube, the needle loading device and other components, so as to realize the loading of roller needles of different specifications and the loading of one-way bearings of different specifications and sizes, and has the characteristics of strong versatility and modularity.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
