Brief description of the drawings
Fig. 1 is the structural representation of the utility model Grain with liner end face punching shaping drill bit assembly.
Detailed description of the invention
By describing technology contents of the present utility model, structural feature in detail, being reached object and effect, below in conjunction with embodiment and coordinate accompanying drawing to be described in detail.
Refer to Fig. 1, the utility model Grain with liner end face punching shaping drill bit assembly comprises that spacing positioning sleeve 1, drive bevel gear rotation input component 2, rotary screw rod 3, driven wheel of differential rotate input component 4, adjusting washer (disk) 5, spring base 6, spring 7, nut 8, friction shim 9, overcoat 10, spanner drill chuck 11, unit-type drill head 12 and adjustment screw 13.Described drive bevel gear is rotated input component 2 and is connected driven wheel of differential rotation input component 4.Described overcoat 10 has and runs through upper surface 101 that this overcoat is relative and the cavity 103 of lower surface 102.This cavity 103 formed by the first cavity 1031 and the second cavity 1032 and the first cavity 1031 and the second cavity 1032 between be provided with step 1033.The upper surface 101 of overcoat 10 is provided with described driven wheel of differential and rotates input component 4.On described step 1033, be provided with described friction shim 9.On friction shim 9, be provided with described nut 8.Described spring base 6 has two and be arranged at respectively this nut 8 and the first cavity 1031 tops and be positioned at the first cavity 1031.Described spring 7 two ends are resisted against spring base 6.Described rotational lead screw 3 has relative first end and the second end, on first end, be provided with described spacing positioning sleeve 1, the second end passes with described spanner drill chuck 11 and is connected with nut 8 and from the second cavity through described cavity, and described unit-type drill head 12 is installed on this spanner drill chuck 11.The described driven wheel of differential of this spacing positioning sleeve 1 distance rotates the default stroke in upper surface of input component 4, in the present embodiment, described spacing positioning sleeve 1 comprises stop collar and stop screw, wherein, described stop collar is placed on described rotational lead screw and is provided with screw, and described stop screw is resisted against described rotational lead screw through described screw.Regulate the distance between stop collar and the upper surface of driven wheel of differential rotation input component 4 by stop screw being positioned to the diverse location of rotational lead screw 3.The sidepiece of described overcoat 10 is provided with perforation, and this perforation is through to described cavity 1 inside from the outer surface of overcoat, and described adjustment screw 13 is resisted against described nut 8 through described perforation.
Please continue to refer to Fig. 1, operation principle of the present utility model is as follows:
First, according to workpiece 14(shaping Grain with liner to be punched) aperture and hole depth, adjust and install corresponding unit-type drill head 12 at pre-shaping powder column initially on combustion face, the distance (bit run) stop screw of spacing positioning sleeve 1 being resisted against through the through hole of stop collar on rotational lead screw 3 and spacing positioning sleeve 1 and driven wheel of differential are rotated input component 4 upper surfaces equals hole depth, certainly, stop screw is resisted against the diverse location of rotational lead screw 3 and obtains different hole depth values;
Then, drive bevel gear transmission input component 2 drives driven wheel of differential transmission input component 4 to rotate, utilize flat key to synchronize rotation with drive lead screw 3, because spring 7 two ends are resisted against nut 8 and the first cavity top, so, the force of sliding friction that nut 8 rotates is greater than the circumferential frictional resistance of slip between nut 8 and drive lead screw 3, nut 8 is static, now, described adjustment screw 13 is resisted against through described perforation on described nut 8 (in the time that ball-screw 3 dallies, adjustment screw 13 is not from perforation back-out and against nut 8), further make nut 8 static, thus, it is descending that drive lead screw 3 drives unit-type drill head 12 to rotate, realize the technological requirement of punching plastic operation, can make as required drive bevel gear transmission input component 2 rotate backward simultaneously, thus, drive rotational lead screw 3 repercussions to rotate and that unit-type drill head 12 is rotated is up, after unit-type drill head 12 is up, between unit-type drill head 12 and workpiece 14, just there is space and can remove unit-type drill head and run the medicine bits on bits groove, reduce friction and increase security, ensure the security reliability of operation.When drilling operation is during to default (determining) stroke, but the stop collar of spacing positioning sleeve 1 is positioned at the upper surface of driven wheel of differential transmission input component 4, rotational lead screw 3 cannot be continued descending still in rotary state, like this, to make ball-screw 3 and nut 8 frictional force in a circumferential direction be greater than that spring 7 is resisted against on nut 8 and the end-face friction producing, so, drive lead screw 3 and nut 8 one are in interior default (determining) position idle running of cavity 1, unit-type drill head 12 rotates but is not descending, excision hole root medicine bits, realize punch device and draft technical indicator.When this structural design, use standard rolling bearing at the place of being rotatably assorted, stability of rotation, axiality is high, in the effective rated travel of maximum, unit-type drill head stroke is accurately controlled and can dally in precalculated position, excision hole root medicine bits, and whole process can be reversed, remove unit-type drill head 12 and run the medicine bits on bits groove, reduce friction.
In this step, according to product punching shaping process technical requirement, rotating drive bevel gear rotates input component 2 and drives unit-type drill head 12 with certain rotating speed and the downstream rate plastic operation that punches, guarantee that rotating speed and downstream rate meet product punching shaping process technical requirement, 10mm under the every brill of General Requirements in punching plastic operation process, returning brill cleaning medicine considers to be worth doing once to secondary, whole punching shaping process is returned brill cleaning medicine bits and is no less than 3 times, after putting in place, continue idle running 2～3 weeks, excision hole root medicine bits, rotating backward drive bevel gear rotates input component 2 and drives unit-type drill head 12 to be withdrawn into pre-shaping powder column initially on combustion face with certain rotating speed and speed uplink, adjust powder column to correspondence position, start lower work step operation.The scene that should carry out in operation process after the front preparation of operation and the end of job arranges and frock periodic cleaning maintenance work.
