Abstract
The utility model discloses a unidirectionally rotary feeding device for machining a part of a small general gasoline engine, so as to solve the problems that in the prior art, intermittence frequency of manual operation is always unfixed, and the machining cooling effect is not good. The unidirectionally rotary feeding device for machining the part of the small general gasoline engine comprises a case, and further comprises a push rod connected with the case in a sliding manner, an output shaft rotationally connected with the case, a small ratchet wheel fixed on the output shaft, a big ratchet wheel fixed on the output shaft, a working fixture fixed on the output shaft, a check lever, and a drive claw hinged to the push rod; a torsion spring is connected between the drive claw and the push rod; the drive claw is matched with the small ratchet wheel; one end of the check lever is hinged to the case; the other end of the check lever is connected with the case through a spring; the middle part of the check lever is provided with a tooth-shaped protuberance which is matched with the big ratchet wheel; the push rod is also provided with a stop pin which is is abutted with the check lever; a first limit switch and a second limit switch are arranged at positions, close to the other end of the push rod, on the case. The unidirectionally rotary feeding device disclosed by the utility model is simple in structure and high in practicability.
Description
Technical field
The utility model relates to logical machining technique field, is specifically related to a kind of logical machine part processing one-way rotation work feeder.
Background technique
Logical machine refers to the petrol engine except automobile-used and specific use, and it is mainly as the supporting power of agricultural equipment for plant protection, small farm machine, graden machine, generator set, building machinery, outboard machinery etc.Because general small-size gasoline engine volume is little, lightweight, low price, easy to use, so occupy critical positions in various machine coordinations.Particularly among backpack machinery, general small-size gasoline engine unique supporting power especially.
On logical machine in the manufacturing process of some parts, need workpiece can only rotate and processing intermittently also need to carry out cooling along direction man-hour adding, at present, the processing of this class part relies on artificial dependence experience to operate substantially, this not only has high requirement to workman, and manual operation chopper frequency is often unfixing, processing cooling effect is bad.
Model utility content
The utility model is intended to provide a kind of logical machine part processing one-way rotation work feeder, does not often fix the bad problem of processing cooling effect to solve manual operation chopper frequency in prior art.
Logical machine part processing one-way rotation work feeder in this programme, comprise cabinet, also comprise the push rod being slidably connected with cabinet, the output shaft being rotationally connected with cabinet, be fixed on the little ratchet on output shaft, be fixed on the large ratchet on output shaft, be fixed on the filing appliance on output shaft, check lever and be hinged on the driving claw on push rod, between driving claw and push rod, be connected with torsion spring, driving claw mates with clavula wheel, check lever one end is hinged on cabinet, the check lever the other end is connected by spring with cabinet, check lever middle part is provided with the detent projection of mating with large ratchet, on push rod, be also provided with the backing pin offseting with check lever, on cabinet, be provided with the first limit switch and the second limit switch near push rod the other end place, little ratchet comprises left-half and right half part, on the end face of left-half and right half part, be equipped with inverted cone projection and inverted cone draw-in groove.
Compared with prior art, the utility model has the advantages that: under working state, push rod forward moves, by backing pin, check lever is separated with large ratchet, drive little ratchet, output shaft forward by driving claw simultaneously, when triggering after the first limit switch, push rod oppositely moves, and now driving claw and little ratchet skid, and cannot drive clavula wheel to rotate, check lever blocks large ratchet under spring action simultaneously, prevent output shaft rotation, when push rod triggers after the second limit switch, push rod again forward moves, so just, can realize unidirectional intermittent movement, and chopper frequency is fixed; Little ratchet comprises left-half and right half part, on the end face of left-half and right half part, be equipped with inverted cone projection and inverted cone draw-in groove, left-half and right half part can be assembled into a complete little ratchet by chimeric combination of projection and draw-in groove, such structure makes little ratchet when pulling down on output shaft, only left-half need be struck vertically from right half part, little ratchet can be taken off, take off convenient disassembly and do not need that little ratchet is moved to output shaft end vertically; To sum up, the utility model is simple in structure, and chopper frequency is fixed, processing good cooling results.
Further, between push rod and cabinet, be slidably connected by abrasive rubber circle, reduce the wearing and tearing of push rod.
