[0031] The present invention will be further described below with reference to specific embodiments of the present invention. Figure 1 — Figure 4 :

[0032] A bolt pre-installation device for a hub shaft head comprises a feeding guide rail 2 connected to a vibrating disk 1 at one end, a motor mounting seat 3 with a longitudinally placed servo motor 30 at the bottom provided at the other end of the feeding guide rail 2, a wire feeding ring outer ring 4 is fixed on the top of the motor mounting seat 3, and a feeding port 40 is provided on the side wall of the wire feeding ring outer ring 4, which is abutted against one end of the feeding guide rail 2, the output shaft of the servo motor 30 extends out of the upper end of the motor mounting seat 3, and a wire feeding ring inner ring 5 rotating inside the wire feeding ring outer ring 4 is fixed to the protruding part, a plurality of bolt notches 50 for embedding bolts are provided on the outer wall of the wire feeding ring inner ring 5, a feeding mechanism is provided on the top of the wire feeding ring inner ring 5, the feeding mechanism comprises a driving group 6 with up, down, left and right movement, an electromagnetic mounting ring 7 is provided at the bottom of the driving group 6, and a plurality of fixed electromagnets 70 are fixed to the bottom of the electromagnetic mounting ring 7.

[0033] During the implementation process, the bolts are vibrated and loaded by the vibration plate 1 and transported to the feed port of the wire feed ring outer ring 4 through the feed guide rail 2. When the rotating wire feed ring inner ring 5 rotates to the same position as the bolt notch 50 and the feed port 40, the bolts are embedded in the bolt notch 50. The bolts are stacked according to the number of bolts to be pre-installed on the hub axle head. After all the bolt notches 50 are embedded, no bolts can be embedded in the bolt notches 50 even if the wire feed ring inner ring rotates.

[0034] Furthermore, the feeding structure is used to fill all the bolt gaps 50, and then the electromagnetic mounting ring 7 performs electromagnetic adsorption on the bolts, and moves the adsorbed bolts to the corresponding bolt installation positions on the hub axle head. The overall operation is automatic, the gaps are accurate, the processing efficiency is greatly improved, and the error reduction provides great convenience for subsequent assembly work.

[0035] In addition, one end of the feeding guide rail abuts against the discharge port of the vibration plate 1 , and an abutment portion is also provided at the position of the feeding port 40 , facilitating the abutment setting of the end of the feeding guide rail 2 .

[0036] The feed guide rail 2 is composed of two parallel guide rail plates, the tops of which are arranged horizontally. During the bolt feeding process, the screw rod of the bolt moves between the two guide rail plates, while the nut of the bolt rests on the tops of the two guide rail plates.

[0037] Furthermore, the two guide rails are in a certain tilted state, so that the bolts can be easily slid into the feed port 40. The tilting of the two guide rails is achieved by the base bodies at the bottom of the two guide rails.

[0038] Preferably, the driving group 6 includes a cylinder mounting seat 60, a movable truss 61 that slides laterally is provided on the top of the cylinder mounting seat 60, a mounting slide 62 slides on the movable truss 61, a lifting mounting plate 63 that slides up and down is provided on the mounting slide 62, and the bottom of the lifting mounting plate 63 is fixed to the electromagnetic mounting ring 7.

[0039] In the above structure, the drive group 6 is used to move the electromagnetic mounting ring 7 up, down, left and right. During the movement, all the bolts in the bolt gap 50 are adsorbed, and the adsorbed bolts are moved in batches to the bolt mounting holes of the hub axle head, greatly improving the assembly accuracy.

[0040] Preferably, the ends of the movable truss 61 are provided with a first cylinder 64 for driving the mounting plate 62 to slide left and right. The mounting plate 62 is provided with a second cylinder 65 for driving the elevating mounting plate 63 to move up and down. The cylinder control employed enables rapid movement. Alternatively, a servo motor may be used as the driving power source.

[0041] Preferably, the number of the bolt gaps 50 is four, and they are evenly distributed on the outer wall of the wire feeding ring inner ring 5. When the motor shaft of the servo motor 30 at the bottom of the motor mounting seat 3 rotates 90 degrees, the bolt gaps 50 correspond to the feed port 40.

[0042] In the above structure, since there are four of them, one rotation is evenly divided into four parts. Therefore, the motor shaft of the servo motor rotates 90 degrees. If the number of assembled bolts is 5, it is 72 degrees. Since the electromagnetic mounting ring 7 is replaced and debugged according to actual needs, and the electromagnetic mounting ring is installed in a detachable form, the applicability is improved.

[0043] Preferably, the top of the wire feeding ring inner ring 5 is at the same level as the top of the wire feeding ring outer ring 4. This makes it easier for the bolt to slide in and reduces resistance.

[0044] Preferably, the outer edge of the bottom of the electromagnetic mounting ring 7 is formed with a plurality of downwardly extending protrusions 71 , which facilitate detection of the bolt embedding state in the bolt gap 50 .

[0045] Preferably, the bottom of the motor mounting base 3 is provided with a measuring hole 31 located at the bolt gap 50, and a sensor 32 for monitoring is provided in the measuring hole 31. The sensor 32 is placed at the measuring hole 31 to provide a signal to determine whether the bolt gap is fully embedded in the bolt, thereby improving accuracy.

[0046] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
