Abstract
The utility model relates to an automatic core-expanding alignment and spiral press device, comprising a pressing sleeve, a supporting return spring, a middle press rod, a core-expanding alignment press head, a return rubber ring, a return spring and a connection bolt. The automatic core-expanding alignment and spiral press device is characterized in that the press sleeve and the middle press rod are fixedly connected with each other, the core-expanding alignment press head is used for carrying out core-expanding alignment under the action of the middle press rod, a guiding pin in the press cylinder moves along a guiding slot of the middle press rod so as to allow the middle press rod and the core-expanding alignment press head to rotate, and a piston is screwed into a cylinder body under the action of the supporting return spring. The automatic core-expanding alignment and spiral press device disclosed by the utility model avoids the damage on a seal ring, and reduces the impact damage on each component during pressing; due to the elasticity difference of the two springs, each component works sequentially, and the pressing quality reduction caused by the disorder in a process is avoided; and the press head is of a multi-block separation structure, so that a usable application of the press head is expanded, and the application range of the automatic core-expanding alignment and spiral press device is enlarged.
Description
Technical field the utility model relates to the mechanical press mounting technical field, and core centering and spiral press-loading apparatus automatically particularly rise.
Background technology much press-fits in the work at present, has adopted the press-fit approach that directly is pressed into more, and this press-fit approach pressure assembling force requires bigger; In press-fiting process, not just do not placing if press-fit parts, can cause the damage of corresponding component; Particularly have press-fiting of rubber parts; Damage meeting to rubber parts is very serious, and portioned product rubber parts damage back can cause the assembly product function to lose efficacy as can not in time finding.
The piston of disk brake cooperates with the cylinder body inner seal ring, realizes the sealing function of product.Press-fiting of disk brake piston also adopted the mode that directly is pressed into, usually in press-fiting process; If piston is not just being placed, during vertical compression, can cause the damage of sealing ring; For disk brake, if the sealing ring damage causes seal failure; Will cause the function that reduces even lose brake, threaten the safety of car load.
The purpose of summary of the invention the utility model provides a kind of core centering and spiral press-loading apparatus of rising automatically; Use this instrument can realize rising core centering and low-angle spiral to press-fit work; It is accurate that assurance press-fits product space, promotes the protection to product component, promotes Product Safety.
The purpose of the utility model realizes through following technical scheme: a kind of core centering and spiral press-loading apparatus of rising automatically is made up of following parts: press-fit sleeve, support back-moving spring, middle depression bar, core centering pressure head, the rubber ring that resets, back-moving spring, connecting bolt rise; It is characterized in that press-fiting sleeve is connected fixing with middle depression bar; Rise by core centering pressure head under the effect of middle depression bar; The core centering that rises, the sleeve inner guide finger moves along the gathering sill of middle depression bar, and the depression bar and the core centering pressure head that rises are rotated in the middle of making; Under the effect of supporting back-moving spring, piston spinning is gone in the cylinder body.
The basic ideas of technique scheme are through improving press-loading apparatus, make the vertical compression phenomenon become screw-in, having avoided the damage to sealing ring; Also reduced the impact injury that press-fits each parts in the process, the difference of two spring forces is carried out each parts job order simultaneously; Avoid process chaotic, reduction press-fits quality, and pressure head adopts the polylith isolating construction; But the scope of application is enlarged, promote the scope of application of product.
Through this improvement, make piston press-fit quality and be improved, reduced the quantity of sealing ring damage, avoided press-fiting the problem of doing over again, reduce production cost.And in press-fiting process, to make piston press-fit in the process pressure assembling force more stable because of spring action, avoided press-fiting in the process piston to the impact of cylinder body, thereby avoided the influence to the cylinder body life-span itself, guaranteed security of products.
Description of drawings Fig. 1 is the structural representation of the utility model.
Among the figure, press-fit sleeve (1), support back-moving spring (2), middle depression bar (3), the core centering pressure head (4) that rises, the rubber ring that resets (5), back-moving spring (6), connecting bolt (7), piston (8).
The specific embodiment is described further the utility model below in conjunction with accompanying drawing and embodiment.
This rise automatically core centering and spiral press-loading apparatus mainly contain several parts and form: press-fit sleeve (1), support back-moving spring (2), middle depression bar (3), the core centering pressure head (4) that rises, the rubber ring that resets (5), back-moving spring (6), connecting bolt (7).
During use, press-fit sleeve (1) and be connected fixingly with middle depression bar (3), when press-fiting, integral body press-fits downwards; After integral body is pressed onto piston (8) inside, receive resistance, rise by core centering pressure head (4) under the effect of middle depression bar (3); The core centering that rises after rise core centering pressure head (4) and piston (8) contact matching, is realized the automatic capturing at piston (8) center; Depression bar (3) stops to move downward simultaneously, continues to move downward and press-fit sleeve (1), during motion; Press-fiting the inner guide finger of sleeve (1) can move along the gathering sill of middle depression bar (3), fixes because press-fit sleeve (1), and the depression bar (3) and the core centering pressure head (4) that rises are rotated in the middle of making; And under the effect of supporting back-moving spring (2), remain on certain pressure assembling force, piston (8) spinning is gone in the cylinder body.
After press-fiting completion, middle depression bar (3) carries out return, press-fits sleeve (1) preferential return under the effect of supporting back-moving spring (2); The depression bar (3) and the core centering pressure head (4) that rises also carry out the return rotation simultaneously, eliminate to press-fit in the process rubber parts slight deformation problem that causes; After press-fiting the complete return of sleeve (1), middle depression bar (3) is also followed return, and rises by core centering pressure head (4) under the effect of back-moving spring (6); First and middle depression bar (3) separates, and rises by core centering pressure head (4) under the effect of the rubber ring that resets (5), also breaks away from piston (8) to cooperate; Reset to original position at last, accomplish the whole process that press-fits.
Through this improvement; Piston is in press-fiting process; Can not carry out vertical cut to the rubber parts of cylinder interior again, thereby avoid piston to press-fit in the process, promote product and press-fited quality the damage of rubber parts; And reduced that brake braking ability that the damage because of sealing ring causes reduces or the generation probability of Problem of Failure, thereby guaranteed car load and driver and crew's security.Through reducing quality problems, reduce mass loss once more, reduced production cost of products.
