The size is easy to control, the appearance is easy to protect, and the clamp structure is convenient to maintain.

Description

A kind of clamp structure for hinge bush assembling
Technical field
The present invention relates to a kind of clamp structure, especially relate to a kind of clamp structure for hinge bush assembling.
Background technology
Front cover for vehicle hinge is generally by metal plate punching part, bearing pin, assembling bushings.After sheet metal part punching press spindle hole, then survey mounting bush in hole.How being accurately installed in the spindle hole of panel beating by lining, this is one of technical problem urgently to be resolved hurrily.
In the prior art, it is shaping that disposable flange installed by lining, and the defect of the aspects such as lining is wrinkling, folding, lining aperture is uneven, flange diameter is inadequate, thickness is unstable often occurs.Finally cause hinge assembly moment of torsion unstable, cause bad scrapping, increase manufacturing cost.
Summary of the invention
Object of the present invention be exactly provide that a kind of size is easy to control, outward appearance is easily protected to overcome defect that above-mentioned prior art exists, the clamp structure for hinge bush assembling easy to maintenance.
Object of the present invention can be achieved through the following technical solutions:
For a clamp structure for hinge bush assembling, be made up of lining gland and bearing pin,
Establish through hole in described lining gland, bottom connects panel beating, lining laminating through-hole wall to be processed, and described bearing pin is convex shape, and the root of its protrusions is round and smooth intermediate incline structure, and the angle of this ramp structure and horizontal direction is 45 °,
Processing technology comprises employing lining 45 ° of pre-flange and final pressing two operations, and turning over system 45 ° of flange is in advance in order to progressively shaping with quality such as the apparent sizes ensureing flange.Mainly with Upper Die-sleeve and the composition of bearing pin below fixture group.When after bearing pin press-in bush hole, gasket end, in bearing pin root 45 ° of hypotenuse structures, forms 45° angle degree, finally to pressing operation, lining flange is flattened into dimensional requirement by second again.
Described lining gland and bearing pin adopt Cr12 metal material to be quenched into HRC56-62.
Described lining gland and the surface smoothness of bearing pin are at Rm0.8.
The diameter multistage variable of described bearing pin, matches with the diameter of lining to be processed, can prefabricated 2-3 root near the 0.01mm basic size of interval, can regulate bush hole diameter, to regulate hinge moment of torsion after replacement.
Described lining gland and the flange pressure that bearing pin is adding man-hour are not less than 0.5MPa, and as preferred embodiment, flange pressure adopts 0.5-1MPa.
Compared with prior art, the present invention has following advantage:
One, size is more prone to control: shaping lining flange, and outside diameter and bush hole diameter equidimension are guaranteed;
Two, outward appearance obtains protection: 45 ° of preformed are progressively shaping in two steps with pressing, guarantee that flange outward appearance is guaranteed.
Three, easy to maintenance: by replacing pin diameter, the diameter of bush hole can be controlled, be convenient to regulate hinge moment of torsion.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, 1 be lining gland, 2 be panel beating, 3 be bearing pin, 4 for lining.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
For a clamp structure for hinge bush assembling, its structure as shown in Figure 1, is made up of lining gland 1 and bearing pin 3.Through hole is established in lining gland 1, bottom connects panel beating 2, lining 4 to be processed is fitted through-hole wall, bearing pin 3 is convex shape, the root of its protrusions is round and smooth intermediate incline structure, and the angle of this ramp structure and horizontal direction is 45 °, conveniently uses, lining gland 1 and bearing pin 3 adopt Cr12 metal material to be quenched into HRC56-62, and surface smoothness controls at Rm0.8.In addition, the diameter multistage variable of bearing pin 3, matches with the diameter of lining to be processed, can prefabricated 2-3 root near the 0.01mm basic size of interval, can regulate bush hole diameter, to regulate hinge moment of torsion after replacement.
The processing technology utilizing the present invention to process lining 4 comprises employing lining 45 ° of pre-flange and final pressing two operations, and turning over system 45 ° of flange is in advance in order to progressively shaping with quality such as the apparent sizes ensureing flange.Mainly with Upper Die-sleeve and the composition of bearing pin below fixture group.When after bearing pin press-in bush hole, gasket end, in bearing pin root 45 ° of hypotenuse structures, forms 45° angle degree, finally to pressing operation, lining flange is flattened into dimensional requirement by second again.Lining gland and the flange pressure that bearing pin is adding man-hour are not less than 0.5MPa, such as 0.5-1MPa can be adopted, in the present embodiment, flange pressure is 1MPa, lining gland 1 and bearing pin 3 constitute upper and lower clamp structure, when bearing pin 3 enters lining, start by bearing pin rectilinear end correcting lining 4, after ends contact bearing pin 45 ° of hypotenuses of lining 4, be shaped to 45 °.The reason that second step operation is same, just this time is that lining 4 is flattened.
