Abstract
The invention discloses a mechanism for general gasoline engine processing. The mechanism is aimed at solving the problems of erratic interval frequency caused by manual operation and poor cooling effect in processing in the prior art. The mechanism comprises a frame, an input shaft which is rotatingly connected with the frame, a first fixed block which is connected with the frame and an output shaft which is rotatingly connected with the first fixed block. The mechanism further comprises a second fixed block which is connected with the frame, a fixture block, wherein one end of the fixture block is hinged to the second fixed block, a dual-ratchet wheel which is arranged on the output shaft and a driving block which is mounted on the input shaft. The dual-ratchet wheel comprises a big ratchet wheel and a small ratchet wheel and a roller wheel is respectively arranged at each end of the driving block. A pin which is capable of pressing against spaces between gear tooth of the big ratchet well is arranged at one end of the fixture block away from the second fixed block and a reset spring are mounted between the fixture block and the frame. A clamping which is used for fixing work pieces is arranged on the output shaft. The driving block a left part and a right part and an inverted-cone lug and an inverted-cone clamping slot are respectively mounted on the end surface of the left part and the right part. The mechanism for general gasoline engine processing has the advantages of being simple in structure and good in practicability.
Description
Technical field
The present invention relates to gasoline engine processing technique field, be specifically related to a kind of logical machined mechanism.
Background technology
Logical machine refers to the gasoline 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, generating 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 is unique supporting power especially.
On logical machine in the processing and 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.
Summary of the invention
The invention is intended to provide a kind of logical mechanism for machined, often fixing to solve in prior art manual operation chopper frequency, the bad problem of processing cooling effect.
Logical in this programme mechanism for machined, the output shaft that comprises frame, is rotationally connected power shaft, is connected to the first fixed block in frame and is rotationally connected with the first fixed block with frame, also comprises the hinged fixture block of the second fixed block, one end and the second fixed block that are connected in frame, is located at the two ratchets on output shaft and is located at the drive block on power shaft; Two ratchets comprise large ratchet and little ratchet, drive block two ends are equipped with roller, fixture block is provided with the pin that can be against large ratchet wheel between cog away from second fixed block one end, between fixture block and frame, be also connected with back-moving spring, on output shaft, be also provided with the clip of fixation workpiece, drive block comprises left-half and right half part, is equipped with back taper projection and back taper draw-in groove on the end face of left-half and right half part.
Compared with prior art, advantage of the present invention is: under duty, and power shaft forward, roller drive by drive block one end presses to fixture block, makes fixture block pin depart from large ratchet, and the roller of the drive block other end drives ratchet to rotate simultaneously, treat that ratchet turns over certain angle, roller departs from fixture block, and fixture block resets, ratchet is static, during power shaft reversion, fixture block is tightly against on large ratchet, skids between roller and little ratchet simultaneously, and so forth, realize unidirectional intermittent movement; Drive block comprises left-half and right half part, on the end face of left-half and right half part, be equipped with back taper projection and back taper draw-in groove, left-half and right half part can be assembled into a complete drive block by chimeric combination of projection and draw-in groove, such structure makes drive block when pulling down on driven shaft, only left-half need be struck vertically from right half part, drive block can be taken off, and do not need that drive block is moved to driven shaft axle head vertically, not take off, convenient disassembly; To sum up, the present invention is simple in structure, and chopper frequency is fixed, processing good cooling results.
Further, power shaft middle part is rotationally connected by bearing and frame, strengthens stability.
Further, between the first fixed block, the second fixed block and frame, be bolted layout for convenience detach.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of mechanism for implementing example for the logical machined of the present invention.
The specific embodiment
Shown in Fig. 1, logical in embodiment of the present invention mechanism for machined, comprise frame, with frame be rotationally connected power shaft 1, bolt be connected to the first fixed block in frame and with the output shaft 2 that the first fixed block is rotationally connected, also comprise that bolt is connected to the hinged fixture block 3 of the second fixed block, one end and the second fixed block in frame, is located at the two ratchets 21 on output shaft 2 and is located at the drive block 11 on power shaft 1; Two ratchets 21 comprise large ratchet and little ratchet, drive block 11 two ends are equipped with roller, fixture block 3 is provided with the pin that can be against large ratchet wheel between cog away from second fixed block one end, between fixture block 3 and frame, be also connected with back-moving spring, on output shaft 2, be also provided with the clip of fixation workpiece, drive block 11 comprises left-half and right half part, is equipped with back taper projection and back taper draw-in groove on the end face of left-half and right half part, and power shaft 1 middle part is rotationally connected by bearing and frame.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic is not done too much description at this.Should be understood that; for a person skilled in the art, not departing under the prerequisite of structure of the present invention, can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
