Definitions

  • the disclosure generally relates to fixtures, and particularly to polishing fixtures for polishing molded housings.
  • Electronic device housings manufactured by injection molding usually have parting lines in the outer surface after being molded.
  • the parting lines damage the aesthetical appearance of the electronic device. Therefore, it is necessary to remove the parting lines by polishing.
  • the high polishing temperature of the cover may burn the operators' hands.
  • FIG. 1 is an isometric view of a polishing fixture of an exemplary embodiment.
  • FIG. 2 is an exploded view of the polishing fixture shown in FIG. 1 .
  • FIG. 3 is an isometric view of a housing used to be positioned by the polishing fixture shown in FIG. 1 .
  • FIG. 4 is similar to FIG. 1 , but the polishing fixture is in use with a housing shown in FIG. 3 .
  • FIG. 5 is an isometric view of the polishing fixture shown in FIG. 4 .
  • FIGS. 1 and 2 show an exemplary polishing fixture 100 used to fix a housing 200 in a process of polishing the outer surface 202 of the housing 200 .
  • the polishing fixture 100 includes a body 10 , two fixing members 20 and a pushing member 30 .
  • the fixing members 20 are mounted on the two opposite sides of the body 10 .
  • the fixing members 20 move along a first direction X, from one side of the body 10 to the other opposite side.
  • the pushing member 30 move towards the body 10 along a second direction Z, vertical to the first direction X.
  • the body 10 includes two opposite side walls 12 , two opposite main walls 14 and two opposite end walls 16 .
  • the body 10 has three first guide pins 122 fixed on the each side wall 12 .
  • the first guide pins 122 guide the fixing members 20 to move relative to the body 10 along the first direction X.
  • the body 10 further defines two holes 124 through the side walls 12 .
  • the polishing fixture 100 further includes two elastic members 40 . Each elastic member 40 is retained in the corresponding hole 124 .
  • the elastic members 40 are fixed to the fixing members 20 pressing the fixing members 20 on the side walls 12 .
  • the main wall 14 opposite to the pushing member 30 defines a containing slot 142 and two threaded holes 144 .
  • the containing slot 142 contains portions of the pushing member 30 when the pushing member 30 moves towards the body 10 .
  • the main wall 14 defines two second guide pins 146 .
  • the second guide pins 146 guide the pushing member 30 to move relative to the body 10 along the first direction Z.
  • Each fixing member 20 defines two pressing surfaces 21 , two wedge surfaces 22 , three first guide holes 24 and two fixing slots 26 near the body 10 .
  • the pressing surfaces 21 and the wedge surfaces are located near the side walls 12 , and each pressing surface 21 is connected to the corresponding wedge surface 22 .
  • Each first guide pin 122 is slidably mounted in the corresponding first guide hole 24 to guide the fixing members 20 to move relative to body 10 along the direction X.
  • Each fixing slot 26 has a fixing pin 262 for fixing the elastic members 40 .
  • the pushing member 30 includes a base board 32 , pushing pillars 34 projecting from the base board 32 and a handle 36 fixed on the base board 32 .
  • the base board 32 defines a fixing hole 322 for fixing the handle 36 , through holes 324 and second guide holes 326 .
  • Each pushing pillar 34 defines a driving wedge surface 342 and a resisting surface 344 connected to the driving wedge surface 342 .
  • Each driving wedge surface 342 is located opposite to corresponding one wedge surface 22 .
  • the driving wedge surfaces 342 press the wedge surfaces 22 to drive the fixing members 30 to move away from the body 10 .
  • the resisting surfaces 344 resist against the pressing surface 21 to stably clamp the pushing pillars 34 between the body 10 and the fixing members 20 .
  • the polishing fixture 100 further includes two screws 50 .
  • Each screw 50 is mounted through the corresponding through hole 324 in the corresponding threaded hole 144 , and can prevent the pushing member 30 from separating from the body 10 .
  • Each second guide pin 146 is slidably mounted in the corresponding second guide hole 326 to guide the pushing member 30 to move relative to body 10 along the direction Z.
  • the housing 200 defines a chamber 240 with an entrance 220 .
  • the housing 200 includes a peripheral wall 260 , enclosing the chamber 240 .
  • each elastic member 40 is retained into the corresponding hole 124 .
  • the fixing members 20 are slidably mounted on the first guide pins 122 by the first guide holes 24 .
  • An external force is provided to expand the elastic members 40 , each end of the elastic members 40 is extruded into the corresponding fixing slot 26 .
  • the ends of the elastic members 40 are fixed in the fixing slot 26 by fixing pins 26 .
  • the stretched elastic members 40 restores to drive each of the fixing members 20 to press against the corresponding side wall 12 of the body 10 .
  • the handle 36 is fixed into the fixing hole 322 of the base board 32 .
  • the pushing member 30 is covered onto the body 10 , and the base board 32 is slidably mounted on the second guide pins 146 with the second guide holes 326 .
  • Each driving wedge surface 342 resists against the corresponding wedge surface 22 .
  • Each screw 50 is fixed into the corresponding threading hole 144 through the corresponding through hole 324 .
  • the body 10 and the fixing members 20 of the polishing fixture 100 are positioned into the chamber 240 of the housing 200 through the entrance 220 .
  • the pushing member 30 is driven towards the body 10 along the second guide pins 146 .
  • the wedge surfaces 22 are driven away from the body 10 along the first positioning pins 122 by driving wedge surfaces 22 until each resisting surface 344 is resisted against the corresponding pressing surface 21 .
  • the elastic members 40 are extruded to store an elastic force.
  • the pillars 34 are retained between the body 10 and fixing members 20 by the elastic force, and the fixing members 20 are filled in the chamber 240 and resisted against the peripheral wall 260 .
  • the outer surface 202 of the housing 200 can be polished.
