Detailed description of the invention

Referring to Fig. 1 to Fig. 7 as follows, the present embodiment provides a kind of workbench switching fabric, including:

One rotation platform 10, downwardly extends a main shaft 11 bottom this rotation platform 10, this main shaft 11 is arranged in a shell In body 20；

One active rotating shaft 30, this active rotating shaft 30 one end connects a driving source 40, and another of this active rotating shaft 30 Hold in this housing 20, fasten a driving gear 31；

One first Swing Arm 50, one end of this first Swing Arm 50 is hubbed at this housing 20 inwall, and this first shakes Swing arm 50 is pivoted displacement roller 51 and a cam bawl 52 in homonymy；

One passive rotating shaft 60, fixed one second cam 62 and one first cam is respectively inserted at these passive rotating shaft 60 two ends 61, and this passive rotating shaft 60 wears the other end of this first Swing Arm 50 again and fastens a driven gear 63, this quilt Moving gear 63 engages this driving gear 31, and the external diameter of this cam bawl 52 of this first Swing Arm 50 corresponds to The external diameter of this first cam 61, this displacement roller 51 is arranged in the side of this main shaft 11 and is positioned at this rotary flat simultaneously Below platform 10, this passive rotating shaft 60 at least one end is pivoted this housing 20 inwall be parallel to this active rotating shaft in addition 30；

One second Swing Arm 70, one end of this second Swing Arm 70 be hubbed at this housing 20 inwall and relative to this The opposite side of one Swing Arm 50, furthermore this second Swing Arm 70 homonymy be pivoted the external diameter pair of another this cam bawl 52 Should be in the external diameter of this second cam 62, and another this displacement roller 51 that is pivoted is arranged in this main shaft 11 this position relative Move the opposite side of roller 51.

Wherein, the external diameter fixed several spinning rollers 12 of annular of this main shaft 11, respectively this spinning rollers 12 is six.

Wherein, projection one threaded portion 64 between this first cam 61 and this second cam 62, this threaded portion 64 ring sets In recessed three helical pitches 65 of this passive rotating shaft 60 and this threaded portion 64, respectively this helical pitch 65 Corresponding matching rolls in respectively this rotation Son 12.

Wherein, this passive rotating shaft 60 fastens an axle sleeve 80, and this axle sleeve 80 is fixedly arranged on this passive tooth wheel shaft 63 to the center of circle Locate, and this axle sleeve 80 is that second ring element 81 is the most chimeric, and set number perforation 82 in each ring in axial both sides and count blind Hole 83.

Wherein, respectively this each spiral shell of perforation 82 sets a screw 84 in respectively this perforation 82, and screw in relative opposite side should The female thread of this perforation 82 of ring-type element 81 is with packing respectively this ring-type element 81.

Wherein, respectively each spiral shell of the female thread of this blind hole 83 sets a screw 84 in respectively this blind hole 83, and supports respectively that this is blind Bottom order respectively this ring-type element 81 in hole 83 is disengaged from.

When, before this utility model start, the workpiece being first intended to be processed is fixedly arranged in this rotation platform 10 plane Opposite end, and the workpiece of processing end is processed, after work pieces process completes；Now start this reality Interlock this driving gear 31 on this active rotating shaft 30 with this novel driving source 40, and this driving gear 31 engages This driven gear 63 drives this passive rotating shaft 60 to rotate, and this first Swing Arm 50 and the second Swing Arm 70 is each simultaneously This cam bawl 52 external diameter is resisted against this first cam 61 and the external diameter of this second cam 62, due to this first cam 61 differ with the ellipse therefore external diameter angle of bend that this second cam 62 is predetermined design, make this first Swing Arm 50 and this second Swing Arm 70 swell with the external diameter of this first cam 61 and this second cam 62 and rise, and related Make respectively this displacement roller 51 upwards support this main shaft 11 opposite sides, allow this rotation platform 10 slowly rise but do not produce It is conigenous and turns；

Then this main shaft 11 is when rising to displacement stroke top, respectively this most related shifting up of spinning rollers 12 and with Time engage respectively this helical pitch 65 of this threaded portion 64, respectively this helical pitch 65 drives respectively this spinning rollers 12 to make this rotation Platform 10 is with center of circle rotation 180 degree；

After furthermore this rotation platform 10 completes to rotate, owing to this first cam 61 and this second cam 62 turn to respectively During the mild external diameter of this cam follower, make respectively this displacement roller of this first Swing Arm 50 and this second Swing Arm 70 51 to bottom offset, allows this main shaft 11 slowly stop rotation down to end of travel simultaneously, and is iteratively repeated above-mentioned Action makes this rotation platform 10 two end pieces automatically exchange.

By constructed above, the had advantage of this utility model is as follows: being somebody's turn to do of this active rotating shaft 30 of the present utility model Driving gear 31 engages this driven gear 63 and interlocks this passive rotating shaft, when passive rotating shaft drive this first cam 61, This second cam 62 and this threaded portion 64 synchronous axial system, thus this first Swing Arm 50 and this second Swing Arm The external diameter of respectively this cam bawl 52 of 70 follows this first cam 61 and the external diameter of this second cam 62, make this first Respectively this displacement roller 51 of Swing Arm 50 and this second Swing Arm 70 supports this main shaft 11 in rule dipping and heaving position Moving, thereby when this main shaft 11 is to move to stroke top, respectively this spinning rollers 12 engages this screw thread of this passive rotating shaft Portion 64, drive respectively this spinning rollers 12 make this rotation platform 10 rotate 180 degree, completed workpiece with Article position to be processed is mutually changed, and carrys out the other end unloading of convenient processing or fixes workpiece, to reach processing Operation smooth and easy and promote working (machining) efficiency effect.
