Take turns and be sintered in upper friction plate, the lower friction plate composition in ratchet upper/lower terminal face.The assembling work of bottle gouard moved by hands is related to overlay film
On bearing press mounting to friction plate assembly, and there are the overvoltages of overlay film bearing or under-voltage equal press fitting depth to be difficult to control for existing press fitting device
Deficiency, when overlay film bearing is not pressed onto, the upper end of overlay film bearing is not then completely into the centre bore of ratchet, when overlay film axis
When pressure-bearing is crossed, the lower end of overlay film bearing can be exposed from the central hole of ratchet and be gone out, and easy damaged friction plate assembly, causes to cover
Film bearing deforms, in view of this, existing press fitting device has improvement necessary in fact.
【Invention content】
That the object of the present invention is to provide a kind of press fitting depth is easily controllable, after press fitting demoulding assembly parts take from it is convenient manually
The special press fitting of cucurbit friction plate assembly and overlay film bearing, the special press fitting self poisoning is accurate, and assembly parts positioning is reliable.
For this purpose, the present invention provides the following technical solutions：
The special press fitting of bottle gouard moved by hands friction plate assembly and overlay film bearing, including be sequentially arranged from top to bottom upper mold,
Locating core die holder and bottom plate, locating core die holder are fixed on bottom plate, and positioning core model is equipped between upper mold and locating core die holder, on
Mould opens up upper mold blind hole, upper mold step respectively in its bottom, and locating core die holder has die holder stepped hole and put for friction plate assembly
The die holder top surface set, positioning core model have core model neck, core model shoulder and the core worn for friction plate assembly successively from top to bottom
Mould main part, wherein form the core model shoulder for overlay film bearing placement, core model master in core model shoulder and core model main part transition
Body portion slide fit is in die holder stepped hole, and core model main part is supported on by compression spring on bottom plate, and upper mold blind hole is arranged core model neck,
Core model shoulder is touched in upper mold bottom surface, and the position of upper mold step is just corresponding in interval with die holder top surface.
The center line of the center line of upper mold blind hole, the axial line for positioning core model and die holder stepped hole is total to straight line.
Thickness of the spacing distance of the supreme die station rank in upper mold bottom surface slightly larger than its upper friction plate of friction plate assembly.
The present invention has the following technical effect that：
After positioning the rational core model shoulder of core model setting, the press fitting depth of overlay film bearing is effectively controlled；
Upper mold once unloads return action of the power with compression spring, the bottom surface of friction plate assembly and the die holder top surface of locating core die holder
It disengages, easily the friction plate assembly that tripping is fitted together can be taken together with overlay film bearing on self-positioning core model；Upper mold is blind
Hole is mutually nested with core model shoulder, and core model main part is slidably matched with locating core die holder, to realize upper mold, positioning core model and
The precise positioning of locating core die holder three；Friction plate assembly is nested with core model main part, and friction plate assembly is held on die holder top surface
On, and position core model and offer the core model shoulder placed for overlay film bearing, then it can meet friction plate assembly, overlay film bearing respectively
Reliable location and overlay film bearing and friction plate assembly concentricity.
【Description of the drawings】
Fig. 1 is the structural schematic diagram of the present invention.
Fig. 2 is the schematic diagram of friction plate assembly；
Fig. 3 is the schematic diagram after overlay film bearing press mounting to friction plate assembly.
【Specific implementation mode】
Refer to shown in Fig. 1,2,3, the special press fitting of bottle gouard moved by hands friction plate assembly and overlay film bearing, including from up to
Under the upper mold 1, locating core die holder 2 and the bottom plate 3 that are sequentially arranged, locating core die holder 2 is fixed on by bolt 7 on bottom plate 3, in upper mold
Positioning core model 4 is equipped between 1 and locating core die holder 2, upper mold 1 opens up upper mold blind hole 10, upper mold step 12 respectively in its bottom, fixed
Position core model seat 2 with die holder stepped hole 20 and the die holder top surface 21 shelved for friction plate assembly M, positioning core model 4 from top to bottom according to
It is secondary that there is core model neck 40, core model shoulder 41 and the core model main part 42 worn for friction plate assembly M, wherein in core model shoulder
41 form the core model shoulder 43 for overlay film bearing B placements with 42 transition of core model main part, and 42 slide fit of core model main part is in die holder
