Description
Technical field
The present invention relates to a kind of automatic tapping machine, but relate in particular to a kind of full automatic tapping machine of automatic withdrawal return.
Background technology
Tooth machining unit is the machining equipment that a kind of medial surface of hole of the part in the various through holes with different size such as parts housing, equipment end face, nut, ring flange or blind hole processes internal thread, screw or makes tooth buckle.Existing tooth machining unit generally adopts mechanical arm to carry out the auxiliary positioning tapping mechanism, and mechanical arm itself is without any power source, needs to transfer by staff auxiliary positioning mechanical arm and operation tapping mechanism are positive and negative the advance and retreat cutter work that realizes tapping mechanism.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, but the invention provides a kind of full automatic tapping machine of automatic withdrawal return, need not the staff auxiliary positioning and can automatically complete the tapping overall process, the repetition tapping operation that is particularly suitable for producing in enormous quantities.
Technical scheme: for solving the problems of the technologies described above, the technical solution used in the present invention is:
But the full automatic tapping machine of automatic withdrawal return comprises support, work piece holder, feed mechanism, slide mechanism, buffer gear and tapping mechanism;
Described feed mechanism comprises holder and pushing ram, described slide mechanism comprises slide rail and slide block, described buffer gear comprises feed buffer cell and withdrawing buffer cell, described feed buffer cell comprises feed spring fixed block, feed buffer spring and feed buffer stopper, and described withdrawing buffer cell comprises withdrawing spring fixed block, withdrawing buffer spring and withdrawing buffer stopper;
Described work piece holder, holder and slide rail all are fixed on support, and tapping mechanism is arranged on the tooth machining unit fixture, and described tooth machining unit fixture is fixed on slide block by the tooth machining unit bearing, and described work piece holder is positioned at the left side of tapping mechanism; Described slide rail is parallel with pushing ram; Described withdrawing spring fixed block, withdrawing buffer spring, withdrawing buffer stopper, feed buffer stopper, feed buffer spring and feed spring fixed block are sleeved on pushing ram from left to right successively, and withdrawing spring fixed block and feed spring fixed block are all fixed with pushing ram, and withdrawing buffer stopper and feed buffer stopper are all fixed with the tooth machining unit fixture.
Concrete, when described tapping mechanism tapping was initial, the feed buffer spring was in compressive state; Preferably, after described tapping mechanism had been attacked 2 ~ 3 teeth, the feed buffer spring broke away from compressive state.
Concrete, when described tapping mechanism withdrawing was initial, the withdrawing buffer spring was in compressive state, and after the tapping mechanism withdrawing produced certain displacement, the withdrawing buffer spring broke away from compressive state.
Preferably, described slide mechanism also comprises linear bearing, and the outer ring of described linear bearing is fixed on the tooth machining unit fixture, fix with withdrawing buffer stopper and feed buffer stopper holding position, and described pushing ram passes the inner ring of linear bearing.By the design of linear bearing, can play certain supporting role to pushing ram, improve the robust motion of pushing ram.
In said apparatus, feed mechanism is used for the screw tap of tapping mechanism is pushed to processed hole, coordinates simultaneously buffer gear to provide the tapping initial stage need be applied to pressure on screw tap; Described slide mechanism be used for to limit tapping mechanism feed, withdrawing route, the action that makes the screw tap of tapping mechanism aim at processed hole; Tapping mechanism is used for completing the tapping action.
Before tapping begins, pushing ram is to left movement, drive feed spring fixed block and move to feed buffer spring pressurized thereupon, after the feed buffer stopper is subjected to the feed spring force, drive is fixed on tapping mechanism on the tooth machining unit fixture along slide rail to left movement, aims at processed hole and possesses simultaneously the pressure that the tapping mechanism tapping initial stage needs to the screw tap of tapping mechanism; This moment, tapping mechanism can begin tapping, and after tapping mechanism had been attacked 2 ~ 3 teeth, the feed buffer spring began to break away from compressive state extremely fully not to the tapping mechanism application of force, and tapping mechanism continues tapping along slide rail; When tapping soon finishes, the withdrawing buffer spring begins to enter compressive state, and when finishing to tapping, tapping mechanism is subject to small thrust to the right, when the tapping mechanism withdrawing, this small thrust to the right can avoid screw tap and tapping bits to cohere and the situation that can't withdraw from occurs.
Beneficial effect: but the full automatic tapping machine of automatic withdrawal return provided by the invention need not the staff auxiliary positioning and can automatically complete the tapping overall process, crudy is stable, the repetition tapping operation that is particularly suitable for producing in enormous quantities.
