[0027] EMBODIMENT

[0028] As shown in Figure 1 - Figure 4 The technical solution in the embodiment of the application effectively solves the technical problem of insufficient processing quality of the existing device, and the general idea is as follows:

[0029] In view of the problems in the prior art, the utility model provides an anti-deviation drilling mechanism for mechanical shell, including bench drill device 11, the upper end of bench drill device 11 is equipped with lifting unit 12, and the upper end of lifting unit 12 is equipped with drilling power unit 13;

[0030] The lower end of drilling power unit 13 is equipped with anti-deviation structure;

[0031] The anti-deviation structure comprises a first circular ring 14, a plurality of first locking members 15 are threadedly installed between the first circular ring 14 and the drilling power unit 13, a plurality of circular shafts 16 are fixedly installed at the lower end of the first circular ring 14, a rotating disc 17 is rotatably installed on the circumferential surface of each circular shaft 16, a second circular ring 18 is arranged at the lower end of the first circular ring 14, the second circular ring 18 is located below the circular shaft 16, each circular shaft 16 is fixedly installed with the second circular ring 18, and a second locking member 19 is threadedly installed between each second circular ring 18 and the drilling power unit 13. By optimizing the structure and layout of the device, the anti-deviation structure is integrated between the first circular ring 14 and the second circular ring 18, and the first locking member 15 and the second locking member 19 are used to fix the anti-deviation structure on the drilling power unit 13, thereby achieving the effects of low modification cost and easy to add.

[0032] A soft pad sleeve 21 is fixedly installed on the circumferential surface of each rotating disc 17, a drill jig 22 is arranged at the lower end of the drilling power unit 13, each soft pad sleeve 21 is in contact with the drill jig 22, a drill bit 23 is arranged at the lower end of the drill jig 22, each drill jig 22 and drill bit 23 are located inside the first circular ring 14 and the second circular ring 18, a feed handle 24 is arranged on the side wall of the drilling power unit 13, a base 25 is arranged on the side wall of the lifting unit 12, a vice 26 is arranged at the upper end of the base 25. By arranging the anti-deviation structure, when the worker drills, the worker can rotate the feed handle 24 counterclockwise, so that the drill jig 22 drives the drill bit 23 to descend as a whole to drill the mechanical shell. At the same time, the soft pad sleeve 21 will actively rub with the drill jig 22. At the same time, due to the rotation of the drill jig 22, the rotation of the drill jig 22 will generate a friction force on the soft pad sleeve 21. At this time, when the drill bit 23 drills the mechanical shell on the vice 26 and vibrates, the drill jig 22 will limit the drill jig 22, thereby reducing deviation and improving processing quality.

[0033] Working principle:

[0034] Firstly, when in use, the worker can first clamp the mechanical shell to be drilled in the vice 26 on the base 25, then the worker can start the lifting unit 12 to make the base 25 and the vice 26 drive the mechanical shell to ascend along the lifting unit 12, then the worker can install the first circular ring 14 and the second circular ring 18 on the drilling power unit 13 by using the first locking member 15 and the second locking member 19, and then the worker can start the drilling power unit 13 to make the drill jig 22 and the drill bit 23 rotate.

[0035] Second, the staff can then rotate counterclockwise feed handle 24, so that the drill power unit 13 control spindle and drill die 22 with drill bit 23 overall drop to drill the shell, while the soft pad set 21 will be proactive with drill die 22 friction, while the spindle and drill die 22 rotation, the drill die 22 will rotate at this time the soft pad set 21 generated by the friction, so the turntable 17 will also drive the turntable 17 on the round shaft 16 rotation, at this time when the drill bit 23 on the mechanical shell drill vice 26 vibration occurs, the drill die 22 will provide a limit on the spindle and drill die 22, thereby reducing the offset.

[0036] Finally, it should be noted that: apparently, the above examples are merely for the purpose of clearly illustrating the utility model made, and not limited to the implementation. For those of ordinary skill in the art, on the basis of the above description can also be made in other different forms of changes or variations. Here do not need to and can not all the implementation to be exhausted. The obvious changes or variations derived from still within the scope of the utility model.
