Abstract
The utility model provides a reversed riveting device for press-fit of screws, which is formed by a bottom cover board, a base and a pressing sleeve, wherein the bottom cover board is fixed on the base through screws; the base and the pressing sleeve are fixed through screws; a hole is arranged in the bottom base board; ejecting rubber is filled on the lower portion of the hole; the outer circle of the ejecting rubber is in clearance fit with the hole of the bottom cover board; an ejecting pin is filled at the upper end of the ejecting rubber; and the upper end of the ejecting pin is in clearance fit with a hole of the pressing sleeve. The diameter of the hole of the pressing sleeve should be larger than that of a pressed screw.
Description
Technical field
The utility model relates to a kind of press-loading apparatus, relates in particular to a kind of pressure device that press-fits screw.
Background technology
Present numerous vehicle shock absorber relies on the screw under body on the gripper shoe to be connected, and this screw relies on the hole compression fit on the magnitude of interference and the gripper shoe for the flower screw that flows, and guarantees certain extrusion pressure and moment of torsion, satisfies the entrucking requirement.The process that this screw press-fits common employing is to rely on pressure that screw directly is pressed into the end to get final product.Use screw that the back finds to press-fit like this before entrucking by long-term, because static pressure is exerted oneself inadequately, screw comes off easily, thereby causes the shock absorber can't the entrucking use.
The utility model content
The utility model has just provided a kind of novel anti-riveting device that press-fits screw, improves the extrusion pressure of screw greatly, emits the problem that comes off thereby solved screw.The technical solution of the utility model is as follows:
A kind of anti-riveting device that press-fits screw, by bottom plate, base and gland constitute, and wherein bottom plate is fixed on the base, and base is fixedlyed connected with gland, gland is provided with the pressing sleeve hole of perforation, porose in the bottom plate, material returned rubber is equipped with in the bottom, hole, and the cylindrical of material returned rubber and bottom plate hole are matched in clearance, material returned nail is equipped with in material returned rubber upper end, and the material returned nails on end and pressing sleeve hole matched in clearance.The diameter of pressing sleeve hole should be greater than the diameter that is press-fited screw.
This device designs the gland in different apertures at the different major diameter of thread of screw, the material returned nail different according to the different Design of length of screw, and that can satisfy various screws press-fits the anti-riveting requirement.When using this anti-riveting device, screw and product parts that needs are press-fited are placed on the press-loading apparatus together, press-fit screw and put into pressing sleeve hole, pass through the pressure of hydraulic press this moment to the screw application of force, the conical surface of screw is squeezed on the part by the gland cutting edge, promptly finishes the riveted joint of product screw and product.
When hydraulic press is pressed into the part screw, material returned rubber will be compressed, and when hydraulic press pressure was got rid of, material returned rubber restored to the original state, thereby the power upwards that produces withdraws from screw.The operator takes out part, finishes staking process.
This kind device relies on the method Dou screw of oppositely riveted joint to be riveted on the part of product when the wealth that press-fits, make the screw extrusion pressure improve greatly, thereby has solved the easily problem from the product parts of screw.

Among the figure: 1, gland, 2, pressing sleeve hole, 3, material returned nail, 4, attachment screw, 5, hold-down screw, 6, material returned rubber, 7, base, 8, bottom plate, 9, hydraulic press, 10, product parts, 11, press-fited screw, 12, press-fited the screw conical surface, 13, the gland post, 14, gland bottom plate, 15, the gland cutting edge.
The specific embodiment
Shown in Fig. 1-4, a kind of anti-riveting device that press-fits screw, by bottom plate 8, base 7 and gland 1 constitute, and wherein bottom plate 8 usefulness hold-down screws 5 are fixed on the base 7, and base 7 and gland 1 usefulness attachment screw 4 are fixing; Gland 1 first half is a gland post 13, and Lower Half is to be used for the gland bottom plate 14 that is connected with base, is provided with the pressing sleeve hole 2 of perforation in the gland post 13, and gland post 13 end faces are made gland cutting edge 15; Porose in the middle of the bottom plate 8, material returned rubber 6 is equipped with in the bottom in hole, and the hole of the cylindrical of material returned rubber 6 and bottom plate 8 is a matched in clearance, and material returned nail 3 is equipped with in material returned rubber 6 upper ends, and 3 upper ends and pressing sleeve hole 2 matched in clearance are followed closely in the material returned.The diameter of pressing sleeve hole 2 should be greater than the diameter that is press-fited screw 11.
This device is at being press-fited the gland 1 that the different major diameter of thread of screw designs different apertures, the material returned nail 3 different according to the different Design of length of screw, and that can satisfy various screws press-fits the anti-riveting requirement.When using this anti-riveting device, screw and product parts that needs are press-fited are placed on this device together, being press-fited screw 11 puts into pressing sleeve hole 2, pass through the pressure of hydraulic press 9 this moment to the screw application of force, being press-fited the screw conical surface 12 is squeezed on the product parts 10 by gland cutting edge 15, promptly finishes the riveted joint of product screw and product.
When hydraulic press is pressed into the part screw, material returned rubber will be compressed, and when hydraulic press pressure was got rid of, material returned rubber restored to the original state, thereby the power upwards that produces withdraws from screw.The operator takes out part, finishes staking process.
