DETAILED DESCRIPTION

[0029] The present invention will be described below in conjunction with specific implementation methods.

[0030] Embodiment 1, as Figure 1 and Figure 2 As shown, a hinge lock nut and running-in machine includes a frame 1, the frame 1 is equipped with an automatic running-in component 2, and the automatic running-in component 2 includes a hinge insertion seat 21 for positioning and placing hinge products.

[0031] Among them, Figure 1 and Figure 2 As shown, the frame 1 is provided with a nut vibrating feeder 3 beside the automatic running-in component 2, and the nut vibrating feeder 3 supplies the nuts to the grabbing position in sequence and in an orderly manner; it should be pointed out that, for the nut vibrating feeder 3 of the first embodiment, it is already the prior art and will not be described in detail here.

[0032] Further, such as Figures 1 to 3As shown, the frame 1 is also equipped with a lock nut grabbing assembly 4, which includes a fixed support frame 41 fastened to the frame 1 and an automatic electric screwdriver 43 and a material-grabbing air claw 44 arranged at intervals on the left and right. The fixed support frame 41 is equipped with a driving mechanism 42 for driving the automatic electric screwdriver 43 and the material-grabbing air claw 44 to move in the horizontal and vertical directions.

[0033] Specifically, the driving mechanism 42 includes a horizontal driving module installed on the upper end of the fixed support frame 41, a vertical lifting driving module is installed on the driving end of the horizontal driving module, and the automatic electric screwdriver 43 and the material-taking air claw 44 are installed on the driving end of the lifting driving module. The horizontal driving module and the lifting driving module of the first embodiment can be linear driving modules respectively.

[0034] It should be pointed out that the automatic running-in component 2 is used to run-in the hinge product. Before and after the running-in action, the hinge product remains positioned and placed on the hinge insertion seat 21.

[0035] In the working process of the hinge lock nut and running-in machine of the first embodiment, the steps include:

[0036] Step a, the horizontal driving module of the driving mechanism 42 drives the automatic electric screwdriver 43 and the material picking air claw 44 to move horizontally, and makes the automatic electric screwdriver 43 move horizontally to above the grabbing position of the nut vibration feeder 3 and makes the material picking air claw 44 move to above the hinge insertion seat 21, and then the lifting driving module drives the automatic electric screwdriver 43 to move downward and grab the nut from the grabbing position of the nut vibration feeder 3, and the lifting driving module drives the material picking air claw 44 to move downward so that the material picking air claw 44 grabs the hinge that has been run-in on the hinge insertion seat 21;

[0037] Step b: After the automatic electric screwdriver 43 grabs the nut and the material-taking air claw 44 grabs the pressed and run-in hinge, the lifting drive module drives the automatic electric screwdriver 43 and the material-taking air claw 44 to move upward, and the staff positions the hinge product without the nut screwed on the hinge insertion seat 21;

[0038] Step c, the horizontal driving module drives the automatic electric screwdriver 43 to move above the hinge product, and the horizontal driving module drives the material picking air claw 44 to move to the discharge position of the run-in hinge, and the material picking air claw 44 releases the run-in hinge and realizes the automatic unloading of the run-in hinge;

[0039] Step d, the lifting drive module drives the automatic electric screwdriver 43 to move down to the locking nut position, and the automatic electric screwdriver 43 is activated to screw the nut onto the hinge product to complete the locking nut operation;

[0040] Step e: After the locking nut operation is completed, the automatic running-in component 2 is activated to run-in the hinge product;

[0041] Step f: After the grinding operation of the hinge product is completed, repeat the above steps ae and complete the subsequent hinge product locking nut and grinding operation.

[0042] Based on the above, it can be seen that through the above-mentioned structural design, the hinge locking nut and running-in machine of the first embodiment can realize the hinge product nut locking and running-in functions, and can realize the automatic removal of the hinge after running-in; therefore, the hinge locking nut and running-in machine of the first embodiment has the advantages of novel structural design, high degree of automation, high work efficiency and diverse functions.

[0043] Embodiment 2, as Figure 1 , Figure 2 as well as Figure 4 As shown, the difference between the second embodiment and the first embodiment is that the automatic running-in assembly 2 further includes a rotary drive motor 22 mounted on the frame 1 and arranged vertically, and the power output shaft of the rotary drive motor 22 is tightly connected to the hinge insertion seat 21.

[0044] The upper end of the hinge insertion seat 21 is provided with a hinge insertion slot 211 opening upward and a bracket clamping slot 212 communicating with the hinge insertion slot 211 and opening laterally.

[0045] In addition, a bracket clamping mechanism 23 is installed on the rear side of the hinge insertion seat 21; specifically, the bracket clamping mechanism 23 includes a clamping mounting frame 231 fastened to the frame 1, and a bracket clamping air claw 232 is installed on the upper end of the clamping mounting frame 231.

[0046] When the automatic running-in component 2 of the second embodiment runs in the hinge product, one of the fixed brackets of the hinge product is inserted into the bracket slot 212 of the hinge insertion seat 21, and the other fixed bracket of the hinge product is clamped and fixed by the bracket clamping claw 232. The bracket slot 212 limits the inserted fixed bracket to ensure that the inserted fixed bracket can rotate synchronously with the hinge insertion seat 21; after the hinge product is positioned and placed and each fixed bracket is limited or clamped, the rotation drive motor 22 is activated and the rotation drive motor 22 drives the hinge insertion seat 21 to rotate, thereby causing the fixed bracket that is limited to the hinge insertion seat 21 to rotate, so as to realize the relative rotation of the two fixed brackets of the hinge product and realize the running-in of the hinge product.

[0047] It should be pointed out that, compared with the prior art, in the present embodiment 1, during the running-in operation, one of the fixed brackets only needs to be inserted into the bracket slot 212 limited to the hinge insertion seat 21, without the need to clamp and fix by setting corresponding air claws, so the clamping is more convenient and the structure is simpler.

[0048] Embodiment three, as Figure 1As shown, the difference between the third embodiment and the first embodiment is that the hinge lock nut and running-in integrated machine includes two automatic running-in components 2 and two lock nut grabbing components 4. The two automatic running-in components 2 are arranged on the left and right sides of the nut vibrating feeder 3, and the two lock nut grabbing components 4 are arranged on the left and right sides of the nut vibrating feeder 3.

[0049] During operation, each automatic running-in component 2 cooperates with the lock nut grabbing component 4 on the corresponding side, that is, each automatic running-in component 2 and the lock nut grabbing component 4 on the corresponding side respectively form a group of operating assemblies; during operation, each operating assembly operates at intervals and alternately to multiply the operating efficiency.

[0050] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
