Description
Technical field
The utility model relates to a kind of filter dirt felt cutting forming device, belongs to field of machining.
Background technology
Checking cylinder is the brake part of vehicle, checking cylinder by piston repeatedly compressed air realize skidding to vehicle, yet when sucking air, need stop impurity such as dust to suck in the checking cylinder, can cause cylinder body to scratch, influence the checking cylinder life-span.Therefore, generally the air inlet of forming at the protecgulum of checking cylinder adds filter dirt felt, and to prevent entering of dust etc., therefore filtering the dirt felt plays important protective effect to checking cylinder.Filter dirt felt is a disc-shaped structure, and the centre has aperture.By mould punching press profile, by shape in the desk-top boring processing, two go on foot processed finished products to traditional diamond-making technique then at first, complex steps, waste man-hour, and need artificial location when processing in the desk-top boring processing shape, off-centre takes place easily, causes product percent of pass to reduce.
Summary of the invention
The purpose of this utility model is to adopt the processing of two steps to have complex steps in order to solve when the dirt felt is filtered in tradition processing, manually locatees shortcomings such as qualification rate is low, and a kind of filter dirt felt cutting forming device is provided.
The purpose of this utility model is achieved through the following technical solutions;
A kind of filter dirt felt cutting forming device of the present utility model comprises cutter hub, fairlead, guide post, big spring fixed cover, little spring, big spring, bottom platen, drill bit, steady pin, little spring fixed cover, blade; Guide post is a hollow circular cylinder, and guide post upper end sidewall has two elongated holes that the position is relative, and guide post lower end inwall is fixed with the little spring fixed cover, and guide post lower end outer wall is fixed with the big spring fixed cover, and big spring fixed cover bottom end bearing connects bottom platen; Shape is the ladder cylindrical rotating body in the cutter hub, cutter hub inwall ladder junction is fixed with fairlead, stepped sidewalls has two through holes that the position is relative on the cutter hub, and guide post is inserted in ladder inwall and mutual precision-fit on fairlead and the cutter hub, and fairlead is with big spring outward; Drill bit places guide post inside, and little spring fixed cover and big spring fixed cover are passed in the drill bit lower end, drill bit upper end and steady pin vertical fixing, two elongated holes and two through holes cutter hub sidewall of guide post sidewall are passed at the steady pin two ends respectively, and the drill bit that cutter hub can be driven be connected and fixed pin moves up and down in two elongated hole scopes; Place little spring between steady pin and the little spring fixed cover; Blade is fixed on cutter hub lower end outer wall, and blade is the radius of product apart from the distance of drill bit; The cutter hub upper end links to each other with the drill chuck of bench drill by connector, and it is consistent with bit central that drill chuck rotates the center of circle.
The course of work
Bottom platen is pushed down the filter dirt material that highly processes during cutting filter dirt felt, the drill chuck that rotates, drive the rotation of blade and drill bit, press down cutter hub simultaneously, make blade and drill bit cut filter dirt material simultaneously, lift cutter hub after machining, under bottom platen acts in big little spring, drill bit is not exposed outside in the cutter hub uphill process all the time, cause product to scratch when avoiding drill bit to promote.
Beneficial effect
Cutting forming apparatus structure of the present utility model is simple, easy to operate, and during processing filter dirt felt, disposable finishing improved production efficiency; The structure of the positioning table that adopts has been avoided the generation of eccentric situation, guarantees product quality; When using the dual spring structure to avoid drill bit to promote, cause product to scratch, and solved the potential safety hazard during drill bit is exposed; The utility model can also be applicable to the felt of other type of cutting, and materials such as rubber slab, asbestos board.
