Below in conjunction with the accompanying drawings and embodiment the present invention is described in detail：
Refering to Fig. 1, Fig. 2 and Fig. 3, one embodiment of drill press workpiece auxiliary device for moving of the present invention, a job is included
Platform 10, several rolling members 20 and a driver element 30.
The workbench 10 has a top surface 11, one recessed by the top surface 11 and is in opening up groove 12 and one
It is covered on the capping 13 of the groove 12 opening.
Coordinate ginseng Fig. 4 and Fig. 5, the groove 12 is connected to the groove bottom 121 and the top surface by a groove bottom 121 and one
Trough wall surface 122 between 11, which defines, to be formed, and the contour shape of the groove 12 is in non-circular, and the trough wall surface 122 has several expansions
Footpath portion 123 and several stoppers for being respectively arranged between each two wide diameter portion 123 and being extended internally relative to the wide diameter portion 123
124.The groove bottom 121 is arranged with several guide grooves 14 for corresponding respectively to the wide diameter portion 123 and one is arranged at the guide groove
Between 14 and downward through the axis hole 15 of the bottom of workbench 10, each guide groove 14 is by 141, shallow end 142 of a deep end
And produced by a guiding incline 143 between the deep end 141 and the shallow end 142, the guiding incline 143 is by the court of deep end 141
The shallow end 142 gradually levels off to the groove bottom 121 when extending.
The contour shape of the capping 13 corresponds to the contour shape of the groove 12, and with several corresponding to the top surface 11
Perforate 131, the perforate 131 is in minor diameter part 132 and one that is avette, and respectively having the deep end 141 of the correspondence guide groove 14
The large-diameter portion 133 of the individual correspondence shallow end 142, the internal diameter of the large-diameter portion 133 are more than the minor diameter part 132 and are less than the rolling
The maximum outside diameter of moving part 20 so that the rolling member 20 can be limited in inside the groove 12.
The rolling member 20 is Universal caster, universal rolling and can be installed on inside the workbench 10, the present embodiment four
Individual rolling member 20, centered on the certain point of workbench 10, radial configuration, the apical margin of the rolling member 20 can produce jointly
One copline parallel to the top surface 11, or three rolling members 20 of configuration can also produce 3 coplines.The rolling member
20 also correspond respectively to the wide diameter portion 123.
Coordinate ginseng Fig. 4 and Fig. 5, the driver element 30 is installed on the workbench 10, and corresponds to the rolling with one
The brake 31, one of part 20 is connected to the brake 31 and the actuator 32 stretched out in outside the workbench 10 and an offer
The perseverance of brake 31 keeps down the spring 36 of Subsidence trend.
The brake 31 can be rotatably mounted to the workbench 10, and have an axis hole 15 for being located in the workbench 10
In axostylus axostyle 33, several extension rods 34 for being radially connected to the axostylus axostyle 33 and several be connected to the end of extension rod 34
Carry seat 35.
The axostylus axostyle 33 has a bottom 331 for being piercing in the bottom of workbench 10 and a buckle in the bottom
331 and the axostylus axostyle 33 can be made to be axially positioned the fastener 332 in the workbench 10.
The load seat 35 is stretched at the wide diameter portion 123 respectively, and respectively has a top end face 351, one in contrast to this
Top end face 351 and recessed towards the bottom face 352 by the top end face 351 and be in corresponding to the bottom face 352, one of the guide groove 14
Opening up bearing bore 353, the bottom face 352 have one to should deep end 141 354, high ends 355 of end portion and
One between the end portion 354 and the high end 355 and what is taken the form of inclined plane leads tug portion 356, and this leads the inclination side in tug portion 356
Gradually level off to the top end face 351 to corresponding to the guiding incline 143, and when being extended by the end portion 354 towards the high end 355.
The rolling member 20 is respectively arranged in the bearing bore 353.The perforate 131 of the workbench 10, the guide groove 14, the rolling member
20th, the quantity of the load seat 35 and the bearing bore 353 is all equal.
The interlocking of actuator 32 operates the actuator 32 and can interlock the brake 31 in the bottom 331 of the axostylus axostyle 33
Rotated relative to the workbench 10, and make the load turn in corresponding guide groove 14 of seat 35.
The spring 36 is compression spring, is sheathed on outside the axostylus axostyle 33, and the butted button in the bottom 331 of the axostylus axostyle 33
Between part 332 and the bottom of workbench 10.
For another example shown in Fig. 3, Fig. 4 and Fig. 5, when entirety assembles completion, and operator operates the actuator 32 rotation, can connect
The brake 31 is moved to rotate.When the rolling member 20 is an operating position, now, the load seat 35 of the brake 31
High end 355 is climbed along corresponding guiding incline 143, through by the shallow end 142, until the end portion 354 is located to fastening
The groove bottom 121, and a lateral margin of the rolling member 20 is arranged in the large-diameter portion 133 of the perforate 131 and protruded from respectively
The top surface 11, and when a processing object 100 is positioned on the rolling member 20, in the bottom of processing object 100 and the top
A gap is produced between face 11, and the spring 36 is in contain back the elastic force released by compression shape.And utilize the rolling member 20
The effect that can be installed on inside the workbench 10, can just move the processing object 100 easily universal rolling, and not only causing should
Processing object 100 is easier to move to precalculated position, and operates quite laborsaving during the processing object 100.
When the processing object 100 has been moved into precalculated position, as shown in FIG. 6 and 7, operator operates the actuator 32
When rotating backward so that the brake 31 is interlocked to be rotated also relative to the workbench 10, now, is coordinated ginseng Fig. 4, is utilized this
Elastic force is released in returning for spring 36, and using the brake 31 the load seat 35 lead tug portion 356 and corresponding guiding incline 143 is mutual
The mutually effect of guiding, the end portion 354 can be made smoothly to move and be down to corresponding to the deep end 141, the rolling member 20 is by this
Brake 31 rotates, moved the effect of drop, can be changed by the operating position of script to a reception position, and the rolling member 20 is heavy
Drop in the inside of the workbench 10 and do not protrude from the top surface 11 and the perforate 131.
That is, when the processing object 100 is adjusted to after positioning, reception position is settled down to using the rolling member 20,
The bottom of the processing object 100 can be made to be resisted against the top surface 11, and it is fixed the processing object 100 is produced relative to the workbench 10
Position.When the rolling member 20 is settled down to reception position, the minor diameter part 132 of the perforate 131 is corresponded to respectively.
When being intended to again move the processing object 100 of the workbench 10, the actuator 32 need only be operated again and is rotated, just can be again
As shown in Fig. 3, Fig. 4 and Fig. 5 so that the rolling member 20 is in operating position.
Therefore, operating position of the invention and the conversion operation of the reception position are comparatively simple, can quickly, effortlessly move
Processing object 100, the purpose of the present invention can be reached really.
