The bidirectional tapping machine comprises an input gear, a steering eccentric wheel, a swinging arm and an output gear, wherein one end of the input gear is fixedly connected with a belt wheel coaxial with the input gear, the belt wheel is connected with a belt wheel of a motor through an elastic belt, the swinging arm is fixedly connected with the steering eccentric wheel, the input gear is hinged between the swinging arm and the steering eccentric wheel, and the outer contour of the steering eccentric wheel is hinged to the machine frame; an idle gear which is meshed with the input gear is further hinged to the swinging arm, the output gear can be meshed with the input gear or the idle gear, and the output gear drives a screw tap; the idle gear, the output gear and the input gear are respectively divided into a left half part and a right half part respectively, and the contact end surfaces of each left half part and the corresponding right half part is provided with a reverse conical protrusion and a reverse conical clamping groove, wherein the reverse conical protrusion and the reverse conical clamping groove are mutually connected in a clamping mode. The bidirectional tapping machine can achieve tapping-in and tapping-out without a double-surface motor. Tapping in different depths and different directions can be also achieved.
Description
Technical field
The utility model relates to a kind of parts of screw thread processing, is specifically related to a kind of two-way tooth machining unit for air-conditioning panel thread mill drilling.
Background technology
In the prior art, need to be on air-conditioning panel thread mill drilling so that air-conditioning panel is fixed in air conditioner housing by bolt.General tooth machining unit volume is larger, is generally all to realize attacking and exiting of tapping with two-sided motor.In the time of motor forward, tapping is attacked; In the time of motor reversal, tapping is exited.Transfer with motor positive and negative that to realize the method efficiency of attacking with exiting of tapping low, poor reliability also can make the life-span of motor greatly shorten simultaneously.
Utility model content
Technical problem to be solved in the utility model is to provide one and does not need two-sided motor, can realize the mechanism that tapping is attacked and exited; Also can realize the tapping of different depth and different directions.
In order to solve the problems of the technologies described above, the utility model provides two-way tooth machining unit, comprise input gear, turn to eccentric wheel, swing arm and output gear, described input gear one end is fixedly connected with the belt wheel coaxial with it, described belt wheel is connected with electrical machine belt pulley by elastic belt; Described swing arm with turn to eccentric wheel to be fixedly connected with, swing arm and turn between eccentric wheel and be hinged with input gear, turns to eccentric wheel outline and frame hinged; In described swing arm, be also hinged with idle gear, idle gear and input gear are intermeshing; Described output gear can engage with input gear or idle gear, and output gear drives tapping cone; Described idle gear, output gear and input gear are divided into left-half and right half part, and left-half and contacting of right half part are equipped with back taper projection and the back taper draw-in groove of mutual clamping on end face.
Adopt the two-way tooth machining unit of said structure, in the time of tapping, turning handle, makes swing arm around turning to eccentric wheel central rotation, due to input gear and swing arm hinged, under the drive of swing arm, input gear engages with output gear.Starter motor, motor drives input gear rotation by elastic belt, and input gear drives tapping cone to rotate and starts tapping.After tapping finishes, turning handle, makes swing arm around turning to eccentric wheel central rotation, and idle gear engages with output gear, and output gear reverses and drives the reversion of tapping cone to exit.Motor need not be stopped like this, different the turning to of tapping cone can be realized.If the tapping hand of spiral is contrary, make idle gear first engage with output gear.Because idle gear, output gear and input gear are divided into left-half and right half part, left-half and contacting of right half part are equipped with back taper projection and the back taper draw-in groove of mutual clamping on end face, be convenient to like this replacement and removal of gear.
Further improve as the utility model, described swing arm one end is fixedly connected with the handle that stretches out in input gear.Adopt after this structure, handle can convenient operation person grasp, convenient operation.
Brief description of the drawings
Fig. 1 is the structural representation of the two-way tooth machining unit embodiment of the utility model.
Detailed description of the invention
Reference numeral in Figure of description comprises: output gear 1, and idle gear 2, motor 3, turns to eccentric wheel 4, input gear 5, handle 6, belt wheel 7, swing arm 8.
Below in conjunction with drawings and Examples, technical solutions of the utility model are described in further detail:
As shown in Figure 1, the two-way tooth machining unit of a kind of embodiment of the utility model, comprises input gear 5, turns to eccentric wheel 4, swing arm 8 and output gear 1.Input gear 5 one terminal bolts are connected with the belt wheel coaxial with it 7, and belt wheel 7 is connected with electrical machine belt pulley by elastic belt.Swing arm 8 with turn to eccentric wheel 4 screws to be connected, swing arm 8 and turn between eccentric wheel 4 and be hinged with input gear 5, turns to eccentric wheel 4 outlines and frame hinged, swing arm 8 one end are fixedly connected with the handle 6 that stretches out in input gear 5.In swing arm 8, be also hinged with idle gear 2, idle gear 2 is intermeshing with input gear 5.Output gear 1 can engage with input gear 5 or idle gear 2, and output gear 1 drives tapping cone.Idle gear 2, output gear 1 and input gear 5 are divided into left-half and right half part, and left-half and contacting of right half part are equipped with back taper projection and the back taper draw-in groove of mutual clamping on end face.
In the time of tapping, turning handle 6, makes swing arm 8 around turning to eccentric wheel 4 central rotations, and because input gear 5 and swing arm 8 are hinged, under the drive of swing arm 8, input gear 5 engages with output gear 1.Starter motor 3, motor 3 drives input gear 5 to rotate by elastic belt, and input gear 5 drives tapping cone to rotate and starts tapping.After tapping finishes, turning handle 6, makes swing arm 8 around turning to eccentric wheel 4 central rotations, and idle gear 2 engages with output gear 1, and output gear 1 reverses and drives the reversion of tapping cone to exit.Motor 3 need not be stopped like this, different the turning to of tapping cone can be realized.If the tapping hand of spiral is contrary, make idle gear 2 first engage with output gear 1.
Below described is by reference to the accompanying drawings only preferred embodiment of the present utility model; but the utility model is not limited to above-mentioned embodiment; should be understood that; for a person skilled in the art; do not departing under the prerequisite of the utility model structure; can also make various distortion and improvement, these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
