Description
Technical field
The utility model relates to a kind of for making the device of automobile drum brake shoe, relates in particular to a kind of automobile drum brake shoe assembly bonding jig.
Background technique
Wherein a kind of production method of automobile drum brake shoe sticks on friction plate on brake shoe exactly, and uniform force application when viscose glue is very important to viscose quality, because viscose quality is by the connective stability directly affecting between brake shoe and friction plate; Existing brake shoe assembly bonding jig as shown in Figure 1, its force application spring, oppositely application of force steel band and two rigidity power transmission portion compositions, its rigidity power transmission portion is made up of support and two briquettings, the inner of two briquettings is connected with support, support is connected with force application spring, the exterior edge face of two briquettings withstands on the inner side surface of brake shoe, oppositely application of force steel strap is enclosed within on the outer side surface of friction plate in brake shoe outside, by the two-way function power of reverse application of force steel band and force application spring, brake shoe and friction plate are clamped, thereby complete the bonding of brake shoe and friction plate.
The shortcoming that aforesaid prior art exists is: referring to Fig. 1, through experimental verification, large (the edge that A1, A2 point place is friction plate of the friction plate stress that A1, A2 point place is subject in the drawings, because this place exists lead angle, oppositely the tangential forces of application of force steel band is larger), cause the bonding pressure of this position sticky matter inhomogeneous, in actual production process, there is fracture in friction plate through the A1 that is everlasting, A2 point place; As shown in Figure 1, oppositely application of force steel band can apply inside stress to brake shoe at B1, B2 point place, and existing rigidity power transmission portion cannot be in the inner side of B1, B2 point place brake shoe for brake shoe provides reverse bearing stress, cause brake shoe easily to produce distortion at B1, B2 point place, cause friction plate edge and brake shoe bonding not firm.Further, there is too large deformation at B1, B2 point place for fear of brake shoe, therefore need oppositely to limit the elastic force of force application spring, and less its material stiffness coefficient of spring of elastic force is also relatively little, working life is shorter, needs often to change force application spring, has reduced work efficiency; Due to the restriction to spring force, objectively also just the solidifying pressure of adhesive is proposed to restriction, require the solidifying pressure of adhesive to be less than spring pressure, greatly limit the optional kind of adhesive.
Model utility content
For the problem in background technique, the utility model proposes a kind of automobile drum brake shoe assembly bonding jig, comprise force application spring, reverse application of force steel band and two rigidity power transmission portions, force application spring two ends are connected with the inner side of two rigidity power transmission portions respectively; Side contacts in the outside of rigidity power transmission portion and the wing plate of a brake shoe, wing plate outside and a friction plate inner side bonding; Oppositely application of force steel strap is enclosed within on the outer side surface of friction plate, and its innovation is: described rigidity power transmission portion adopts the holotype pressing plate of platy structure, and holotype pressing plate inner side is connected with force application spring, the interior side contacts of holotype pressing plate outside and wing plate; The profile in holotype pressing plate outside is identical with the profile of wing plate inner side, thereby holotype pressing plate outside is contacted entirely with wing plate inner side.
The working principle of aforementioned means is: adopt after the utility model scheme, because holotype pressing plate outside contacts entirely with wing plate inner side, and holotype pressing plate is solid platy structure, therefore, holotype pressing plate can provide full coverage formula to support to wing plate inner side surface, can effectively avoid stress brake shoe excessive and that cause to be out of shape, farthest guarantee uniformity stressed within the scope of the contact area of friction plate and brake shoe, improve gluing effect.Correspondingly, due to stressed inhomogeneity improvement, also just reduced the restriction to the maximum elastic force of spring, the spring of the larger longer service life of rigidity can be used, avoid spring to change the problem of overfrequency, improved work efficiency, indirectly also just expanded the optional scope of adhesive.
On aforementioned schemes basis, in order further to optimize the stressed of A1, A2 point position friction plate, the utility model has also been done following improvement: the upper and lower both sides of holotype pressing plate are respectively provided with a cushion block, cushion block is positioned at the bending section of reverse application of force steel band and the intersection of flat segments, and cushion block outer surface contacts with reverse application of force steel band.In prior art, owing in corresponding position, cushion block not being set, there is obvious lead angle at friction plate edge in application of force steel band oppositely, the tangential stress of lead angle position is larger, easily cause friction plate local pressure inequality, and after employing aforementioned improved, lead angle position has been transferred to cushion block position from friction plate edge, solve the problem of friction plate local pressure inequality.
Preferably, pad thickness is identical with friction plate thickness.
In view of prior art, the utility model is also provided with a directional post between two holotype pressing plates, and directional post is fixedly connected with the inner side of one of them holotype pressing plate, and directional post is connected with the inside thread of another holotype pressing plate.Be threaded and be convenient to the dismounting of component and regulate the position between holotype pressing plate.
In addition, in order to make the overall stress balance of device, ground same as the prior art, force application spring adopts two dual springs that be arranged in parallel.
Useful technique effect of the present utility model is: can improve the gluing quality of brake shoe and friction plate, guarantee product quality.
