As shown in Figures 1 and 2, it is respectively the structural representation of fixture 10 different angles of a preferred embodiment of the present invention.
Fixture 10 comprises: framework 100, the multiple fixed parts 200 be arranged on framework 100, and is arranged at the abutting part 300 on fixed part 200.
Fixed part 200 comprises installation portion 210 and main part 220.Concrete, installation portion 210 is arranged on framework 100, and main part 220 is arranged on installation portion 210, its free end and installation portion 210 interval are arranged, and be mounted opposite portion 210 can elastics wing, with make free end near or away from installation portion 210, fix workpiece to be added for coordinating with installation portion 210.Also can be understood as, installation portion 210 and main part 220, by elastic dilatation, fix workpiece to be added.Wherein, free end refers to one end of not being connected with installation portion 210.
Abutting part 300 is arranged on main part 220 and/or installation portion 210, and for supporting the inwall of workpiece to be added, namely main part 220 and/or installation portion 210 support the inwall of workpiece to be added by abutting part 300, and then fixing workpiece to be added.
According to actual conditions, also can omit abutting part 300, now, fixture 10 supports the inwall of workpiece to be added by main part 220 and installation portion 210, fixing workpiece to be added.
Above-mentioned fixture 10 such as, for fixedly having the workpiece to be added of groove structure or open cavity, mobile phone shell, bowl cover etc.When using above-mentioned fixture 10, first fixed part 200 is arranged on framework 100, afterwards workpiece to be added is sheathed on fixed part 200.Concrete, make main part 220 overcome elastic acting force by external force, its free end is moved towards installation portion 210; When main part 220 can be placed in the groove structure of workpiece to be added with installation portion 210, remove external force; After removing external force, free end under elastic acting force away from installation portion 210, and support with the inwall of workpiece to be added, and then make installation portion 210 also support with the inwall of workpiece to be added, namely the inwall of main part 220 and installation portion 210 together tensioning workpiece to be added, is fixedly installed on fixed part 200 to make workpiece to be added.After fixing workpiece to be added, carry out following process to machined part, such as, sandblasting etc. is carried out to it.
Above-mentioned fixture 10 fixes workpiece to be added by the elastic reaction of fixed part 200, simplifies the structure of fixture 10, conveniently installs and dismantle workpiece to be added, and then improves the property easy to use of fixture 10.In addition, because fixed part 200 is multiple, can process multiple workpiece to be added simultaneously, improve working (machining) efficiency, shorten the production cycle.
In the present embodiment, framework 100 comprises multiple connecting rod 110, multiple connecting rod 110 is connected to each other, and surround some void region between multiple connecting rod 110, to make fixture 10 when for sandblasting operation, can bidirectional operation be carried out, even sand can be entered in framework 100 from both direction by void region, and with the absorption surface to be added be arranged in framework 100.Like this, the property easy to use of fixture 10 is further increased.
According to actual conditions, multiple connecting rod 110 removably connects.Such as, each connecting rod 110 is equipped with some recesses and protuberance, wherein, recess, for connecting the protuberance on the connecting rod 110 that is adjacent, splices each other to make adjacent two connecting rods 110.Further, the recess on each connecting rod 110 and protuberance interleaved are arranged, and namely often all have a protuberance between adjacent two recesses.For another example, multiple connecting rod 110 also can be spirally connected each other, and namely multiple connecting rod 110 is connected to each other by threaded fastener.Or multiple connecting rod 110 also can magnetic connect each other, concrete, each connecting rod 110 is equipped with magnetic portion, for connecting two connecting rods 110, wherein, connecting rod 110 is made for the adsorbable material of magnetic portion, namely two connecting rods 110 of magnetic portion Adsorption Phase connection simultaneously, now, connecting rod 110 can be provided with the installation position for fixed magnetic portion, such as, installation position is groove, and magnetic portion is placed in groove, to improve the stability of magnetic portion.
Like this, because multiple connecting rod 110 removably connects, make framework 100 assemble according to actual needs, improve the scope of application of fixture 10, make it use flexibility higher.
It should be noted that, according to actual conditions, fixture 10 can also comprise multiple framework 100.Such as, multiple framework 100 is superposed on one another, and removably connects; And for example, multiple framework 100 is positioned at same plane, and removably connects each other, and further, multiple framework 100 can be splicing, clamping, is spirally connected.Like this, further increase the use flexibility of fixture 10 on the one hand, facilitate framework 100 to receive on the other hand.
In other embodiments, fixture 10 also can comprise the gripper shoe be arranged on framework 100.Wherein, gripper shoe is removable installed on framework 100, and is positioned at one end that fixed part 200 fixes workpiece to be added.When workpiece to be added is arranged at after on fixed part 200, gripper shoe and workpiece to be added abut against away from the surface of fixed part 200, are stably arranged on fixture 10 to make workpiece to be added.Like this, when sandblasting is carried out on the surface of the side of sheathed fixed part 200 to machined part, when namely going up the surface sand-blasting of the surface opposite abutted against with gripper shoe to machined part, fixture 10 supports workpiece to be added by gripper shoe, departs from due to the impulsive force of sandblasting and fixed part 200 to avoid workpiece to be added.
In addition, it should be noted that, according to actual needs, gripper shoe also can be offered multiple with fixed part 200 groove one to one.Further, peripheral edge margin gripper shoe being offered groove abuts against with the periphery of the workpiece to be added be fixed on fixed part 200, is exposed by groove to make the work surface of workpiece to be added.Like this, just can pass through the firm workpiece to be added of gripper shoe, and sandblasting can be carried out to machined part from positive and negative both direction simultaneously.
In the present embodiment, multiple fixed part 200 is in matrix distribution, and multiple fixed part 200 is all fixedly installed on framework 100.In other embodiments, fixed part 200 also can be removable installed on framework 100, such as fixed part 200 with framework 100 grafting, be spirally connected, clamping, magnetic is connected.Or fixed part 200 also can slide and be arranged on framework 100, and now, framework 100 is provided with slide rail, fixed part 200 slides and is arranged in slide rail.In addition, according to actual conditions, multiple fixed part 200 also can linearly distribute.
See also Fig. 3, it is the partial enlarged drawing of fixture 10 shown in Fig. 1.
Main part 220 comprise connect successively body 221, connecting portion 222 and support portion 223.Wherein, body 221 is arranged on installation portion 210, connecting portion 222 connects body 221 and support portion 223, support portion 223 and body 221 form angle, and support portion 223 is mounted opposite portion 210 can elastics wing, to change the angle of angle, for supporting the inwall of workpiece to be added, and free end is positioned on support portion 223.
