Description
Technical field
The present invention relates to a kind of rolling fingertip press mounting tool.
Background technology
Rolling fingertip is used for the conduction in relative rotation between parts.As shown in accompanying drawing 15 ~ accompanying drawing 18, certain product comprises rolling fingertip support and is transferred on the product base in rolling fingertip support, wherein rolling fingertip support entirety is short cylinder, its outer round surface is evenly equipped with the rolling fingertip installing hole radially arranged, and is provided with the compressing tablet installing hole communicated with the fingertip installing hole that rolls in side opening.Be provided with the rolling fingertip using spring top pressure in rolling fingertip installing hole, product base is provided with contact block and coordinates with rolling fingertip sliding conduction.In assembling process, need rolling fingertip, latch bracket, spring to be loaded successively in rolling fingertip installing hole, because spring needs to be in compressive state, also need at the rear portion of spring to use compressing tablet by spring along the radial block of rolling fingertip support in rolling fingertip installing hole.Press-fit in process and need to use assembly tool by spring-compressed to certain position, then compressing tablet compressing tablet installing hole is from the side loaded and is stuck in effect installing hole sidewall playing block spring.Because the pilot hole on product is more, need hole-specifically contraposition plugging in fitting instrument during assembling, add that spring-compressed position is wayward, therefore use traditional assembly tool to be inconvenient to operate, assemble effort, efficiency is very low.
Summary of the invention
The object of this invention is to provide a kind of rolling fingertip press mounting tool reducing contraposition number of times, make more convenient operation.
In order to realize above object, the technical solution adopted in the present invention is: a kind of rolling fingertip press mounting tool, and described press mounting tool comprises mount pad, and described mount pad has the Inner arc surface with the external arc surface engagement of the rolling fingertip support that will assemble; Described mount pad is provided with at least two through holes corresponding with the rolling fingertip installing hole on rolling fingertip support along the radial direction on described Inner arc surface; Radially be inserted with towards center in described through hole and press-fit guide rod, described in press-fit guide rod front end and be provided with the fluting corresponding with the rolling fingertip installing hole on fingertip support external arc surface of rolling.
Adopt above structure, the Inner arc of mount pad surface can be located at the external arc of rolling fingertip support on the surface accordingly when press-fiting operation, and adjust mount pad position make on it arrange through hole corresponding with the rolling fingertip installing hole on rolling fingertip support, an alignment operation can complete the contraposition of multiple rolling fingertip installing hole on mount pad, then can use easily and press-fit guide rod by the compressing tablet installing hole loading compressing tablet of spring-compressed to suitable position again from rolling fingertip side face, rotation mount pad after completing, press-fiting of all the other rolling fingertips can be proceeded, thus greatly reduce contraposition number of times, make more convenient operation, raise the efficiency.
As improvement, described mount pad is fixed with the fairlead that bottom is provided with through hole, round platform is provided with in the through hole of described fairlead, describedly press-fit guide rod rear portion and be provided with the shaft shoulder, describedly to press-fit in through hole that guide rod is located in fairlead and to rely on the shaft shoulder to be limited in round platform place on described fairlead, and its rear end is stretched out in the through hole of fairlead; Also be provided with round platform in the through hole of described mount pad, described in press-fit on guide rod be arranged with compression reseting spring between the shaft shoulder and the round platform of described mount pad.Like this can be spacing to each position, hole by press-fiting guide rod, remove from and press-fit guide rod and deviate from hole, and the back-moving spring arranged unclamps after making to have press-fited and press-fits guide rod and can automatically reset, save the action that will press-fit guide rod and extract.
Described fairlead upwards extends and is provided with two parallel lug plates, described in press-fit the part that guide rod stretches out fairlead there are two spin-ended planes of being slidably matched spin-ended with described otic placode; With described, described otic placode top press-fits that guide rod rear end is corresponding is hinged with the eccentric wheel being provided with handle.The spin-ended plane press-fited on guide rod can ensure that its slotted openings direction, front end is fixed, and does not need adjustment can aim at compressing tablet installing hole always; Can control to press-fit the depressed position of guide rod easily by eccentric wheel and keep this position, in addition owing to being provided with compression reseting spring, as long as actuating eccentric wheel handle resets after compressing tablet installation, press-fiting guide rod and also can automatically reset simultaneously, easy to use.
Described press mounting tool also comprises at least one positioning apparatus for circumferential direction, and described positioning apparatus for circumferential direction comprises the positioning pin rod with rolling fingertip installing hole location fit, and described mount pad is radially provided with dowel hole, and described positioning pin rod is inserted in described dowel hole.After contraposition completes, positioning pin rod is inserted the position that can keep rolling fingertip press mounting tool in a rolling fingertip installing hole along dowel hole, improve the situation needing pressing, arrange and multiplely can play better circumferential locating effect.
Described positioning apparatus for circumferential direction comprises front end and is inserted in guide pin bushing in described dowel hole, described guide pin bushing central aperture and be provided with round platform in rear end, and described positioning pin rod front end is provided with the shaft shoulder; Be equipped with Compress Spring between the round platform of described positioning pin rod in described guide pin bushing central aperture and the shaft shoulder of described positioning pin rod and be provided with bearing pin in one end that positioning pin rod stretches out guide pin bushing outside and play position-limiting action.Adopt above-mentioned preferred positioning apparatus for circumferential direction structure, pull-up positioning pin rod during use, unclamps after completing contraposition again, and positioning pin rod can insert, and locates more convenient.
One end that described positioning pin rod stretches out guide pin bushing outside is also provided with for operating the knob gripped, and pulls out positioning pin rod, convenient operation during use by knob.
Described mount pad semicircular in shape, so only need adjust the assembling that twice can complete the whole circle of product, and the setting that positioning pin rod diametrically can be opposed when using positioning pin rod, be convenient to the installation of positioning pin rod.
The Inner arc surface of described mount pad extends the groove being provided with and embedding for rolling fingertip support along inner periphery direction, make location more accurate, avoid axial slip, better guaranteed efficiency.
