Abstract
The utility model discloses an over-electrophoresis protective device for a plate spring bushing. The over-electrophoresis protective device comprises a bolt which penetrates through bushing holes of the plate spring bushing and gaskets which are sleeved on the bolt and are cushioned between corresponding orifices in the plate spring bushing and corresponding parts of the bolt, wherein the gaskets comprise a first gasket which is arranged on the head of the bolt and a second gasket which is arranged at a nut; and SR9170 silicon rubber washers are cushioned between the first gasket and the corresponding orifices of the plate spring bushing and between the second gasket and the corresponding orifices of the plate spring bushing respectively. According to the over-electrophoresis protective device, the silicon rubber washers are made of high temperature-resistant SR9170 silicon rubber, and the inner holes of the plate spring bushing can be sealed effectively while the screwing force of the bolt is reduced by utilizing the elasticity of the silicon rubber washers; and the over-electrophoresis protective device is high in sealing performance, and has characteristics of simple structure, convenience for replacement and capability of being used repeatedly, so that the subsequent assembly of a base plate can be performed smoothly.
Description
Technical field
The utility model relates to a kind of electrophoresis liquid that prevents and is infected with the safety guard of leaf spring lining inwall when the vehicle frame electrophoretic painting.
Background technology
Automobile needs chassis is carried out electrophoretic painting in process of production, need prevent in the coating process that electrophoresis liquid is infected with leaf spring lining inwall.Existing way is to protect with the shutoff of irony pad at the two ends of leaf spring lining; but the stopping property of irony pad is relatively poor; in use often can be for the enhanced leaktightness effect spend because of screwing force and cause greatly the pad distortion; cause seal failure; cause leaf spring lining inwall to be stained with electrophoresis liquid; destroy leaf spring lining inwall dimensional precision, affect the chassis assembling.
The utility model content
The purpose of this utility model is: provide a kind of leaf spring lining simple in structure, good sealing effect to cross the electrophoresis safety guard, easily be out of shape the defective of the seal failure that causes to solve existing leaf spring lining safety guard because of pad.
The technical solution of the utility model is: a kind of leaf spring lining is crossed the electrophoresis safety guard, comprise be used to being located in the bolt in the leaf spring lining trepanning and being set on the bolt and be used for pad and be located at respective apertures on the leaf spring lining and the pad between the bolt corresponding site, described pad comprises the first pad of being located at bolt head and the second pad of being located at the nut place, also fills up respectively between described the first pad and the second pad and leaf spring lining respective apertures and is provided with the SR9170 silicone rubber gasket.
The first pad towards the inner face of leaf spring lining respective apertures also concentric raised be provided with for the boss that stretches into leaf spring lining respective apertures, described boss has for the periphery that coincide and cooperate with leaf spring lining inner-wall surface.
Described the first pad and the bolt head structure that is welded as a whole.
Also pad is provided with the SR9170 silicone rubber gasket between described the second pad and nut.
Leaf spring lining of the present utility model is crossed the electrophoresis safety guard and is adopted to fill up between the pad of bolt and leaf spring lining respective apertures and establish silicone rubber gasket, utilize the elasticity of silicone rubber gasket can be when reducing the dynamics of tightening of bolt the endoporus of effective sealing leaf spring lining, avoid electrophoresis liquid to be infected with leaf spring lining inwall, it is simple in structure, replacing is convenient and the energy Reusability, overcome existing safety guard easily is out of shape the seal failure that causes because of pad problem, guaranteed carrying out smoothly of follow-up chassis assembling.
Description of drawings
Fig. 1 is the structural representation that the utility model leaf spring lining is crossed electrophoresis safety guard specific embodiment.
Embodiment
The specific embodiment that leaf spring lining of the present utility model is crossed the electrophoresis safety guard as shown in Figure 1, this safety guard comprises the bolt 2 that is arranged in leaf spring lining 1 endoporus, be set with at the two ends of bolt 2 and be useful on the first pad 3 and the second pad 5 that pad is located at leaf spring lining 1 respective apertures place, wherein, the first pad 3 is near the head 21 of bolt 2, the second pad 5 is near the nut 22 of bolt 2, be provided with for the boss that stretches into leaf spring lining 1 endoporus in the inner face concentric raised of the first pad 3 towards leaf spring lining 1, the inner hole wall of the periphery of this boss and leaf spring lining 1 coincide.Be useful on pad at the periphery of this boss cover and be located at the first silicone rubber gasket 4 between the first pad 4 and the leaf spring lining 1, pad is provided with the second silicone rubber gasket 6 between the second pad 5 and leaf spring lining 1, in the present embodiment, the first pad 3 is integrally welded with the head of bolt 2, simultaneously, between the nut 22 of bolt 2 and the second pad 5 also pad be provided with the 3rd silicone rubber gasket 7.
During use, with on the boss of the first silicone rubber gasket 4 suit the first pad 3 and bolt 2 is penetrated in the endoporus of leaf spring lining 1, then on bolt 2, put successively the second silicone rubber gasket 6, the second pad 5 and the 3rd silicone rubber gasket 7 is rear tightens with nut 22, can finish the sealing to leaf spring lining 1 endoporus.
Above-mentioned silicone rubber gasket all adopts resistant to elevated temperatures SR9170 silicon rubber to make in the utility model, utilize its elasticity can be when reducing the dynamics of tightening of bolt the endoporus of effective sealing leaf spring lining, it is good airproof performance not only, and have characteristics simple in structure, as to change convenient also energy Reusability, guaranteed carrying out smoothly of follow-up chassis assembling.
