Description
Technical field
The utility model relates to machining equipment, refers to especially a kind of interior facing attachment for the machining piston pin-and-hole.
Background technology
Chamfering in pin-and-hole, be one important operation on piston, and the assembling of piston pin is played a very important role.But the residing position of interior chamfering is a place that is difficult to be worked at the inner chamber of piston.Prior art is the method adopted: add a bulb and frustrate cutter on drilling machine, the hand-held piston of workman then, will in the place of chamfering come to bulb and filed processing.This processing method: one, processing is of low quality, rough, and size is uneven, and can not pour into fully; Two, on the product appearance processed, be difficult to satisfactory; Three, very high to workman's specification requirement, need just can devote oneself to work through long-time training, strengthened the production cost of enterprise, reduce production efficiency; Four, workman's personal safety existed to very large hidden danger.
The utility model content
In order to solve the technical problem existed in prior art, the utility model proposes a kind of interior facing attachment of piston pin hole, its result product quality simple, easy to operate, that process is high.
The technical solution of the utility model is achieved in that a kind of interior facing attachment of piston pin hole, comprising: handle of a knife, the broach shell removably connected with handle of a knife and be arranged on the knife bar in broach shell; Be provided with the knife bar back-moving spring resetted for knife bar between described handle of a knife and knife bar; Be hinged with blade in described knife bar; The tail end of described blade is provided with the blade back-moving spring resetted for blade; Be provided with on described knife bar and promote the thrust unit slided before and after knife bar.
As preferably, described broach shell is provided with the adjusting nut for the adjustable blade angle.
As preferably, in described knife bar and the tail end place of blade is provided with adjustment screw that can adjustable blade back-moving spring elasticity, and described blade back-moving spring is enclosed within on adjustment screw.
As preferably, in described broach shell and near its port, be provided with and prevent that knife bar is from spacing jump ring out in broach shell.
As preferably, described thrust unit comprises and is arranged on the knife bar upper bearing (metal) and is arranged on the pushing block on bearing; Described bearing front end and rear end are respectively equipped with the front end jump ring of rigid bearing and the fixing rear end jump ring of pushing block.
As preferably, described broach shell and handle of a knife are spirally connected.
As preferably, described blade and knife bar are hinged.
The beneficial effects of the utility model are as follows: this apparatus structure is simple, easy to operate; Therefore low to workman's specification requirement, the workman just can devote oneself to work without training, greatly reduces the production cost of enterprise, has improved production efficiency; Not only quality is high but also appearance looks elegant for the product that adopts this device to process; There is not potential safety hazard in workers processing yet.
The accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making under the creative work prerequisite the every other embodiment obtained, and all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of interior facing attachment of piston pin hole, comprise handle of a knife 1, broach shell 3, knife bar 5 and blade 9.Handle of a knife 1 connects broach shell 3 by screw 2, facilitates handle of a knife 1 and broach shell 3 to split.Knife bar 5 is inserted in broach shell 3, and blade 9 is hinged on knife bar 5 by pin 11.Have a through hole that leads to blade 9 tail ends on broach shell 3, adjusting nut 12 is housed in through hole.Adjusting nut 12 promotes blade 9, thereby makes it around pin 11, rotate and change angle.Thrust unit 6 comprises bearing 61 and pushing block 62, and bearing 61 is arranged on knife bar 5, fixing with front end jump ring 7; Pushing block 62 is installed on bearing 61, fixing with rear end jump ring 8.Knife bar back-moving spring 14 1 ends are fixed in handle of a knife 1, and the other end is arranged on the afterbody of knife bar 5.The tail end of blade 9 is equipped with blade back-moving spring 13, in order adjustable blade 9 from knife bar 5 inner chambers, to eject the speed of speed, in knife bar 5, is provided with one and is plugged in together with blade back-moving spring 13, adjustment screw 4 that can adjustable blade back-moving spring 13 elasticities.In order to prevent that knife bar 5 is from the interior ejection of broach shell 3, the port in broach shell 3 is provided with a spacing jump ring 10.
Under free state, blade 9 is to contract in knife bar 5, promotes thrust unit 6, and knife bar 5 moves backward, in the inner chamber of blade 9 knife bars 5, exposes.Blade 9 is twolips, and piston pin hole is enclosed within on knife bar 5, and blade 9 ejects, and piston pushes back, completes the both sides chamfering; Decontrol thrust unit 6, knife bar 5 resets, and blade 9 is retracted, and takes out piston, completes processing.Process simply again fast, there is not any potential safety hazard in the workman yet.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
