Workpiece is set to obtain a correct position.The fixed form of plane and two pitses is typically to be used for bulky cabinet workpiece, this kind of workpiece
It is difficult to carry, when in use, it is easy to interfere and then by alignment pin bending.
Utility model content
For above the deficiencies in the prior art, alignment pin is prevented to be used for one by workpiece damage the utility model proposes a kind of
The dowel device that face two is sold.
To reach above-mentioned purpose, the technical solution of the utility model is：Sliding pin, workbench including being axially arranged with pin-and-hole
And cylinder, the driving section of bulge and lower end of the sliding pin including upper end, the circumference uniform distribution of bulge is provided with least three roads axial direction
Pin-and-hole on the inside of open slot, bulge is provided with inner conical structure, and the diameter of driving section is more than on the inside of the diameter of bulge, driving section
It is axially arranged with the drive cavity that one section of diameter is more than pin-and-hole, the drive cavity is coaxially disposed with pin-and-hole, it is vertical on workbench to be provided with and cunning
The corresponding through hole of bulge of dynamic pin, the bulge of sliding pin coordinates in through hole, and the transmission portion of sliding pin is in workbench
Lower section, the lower horizontal of workbench, which is provided with supporting plate, supporting plate, is vertically arranged cylinder, and output end and the cone pin of cylinder connect
Connect, the upper end of cone pin is provided with male-tapered structure, the pin-and-hole for extending upward into sliding pin of cone pin, in drive cavity
Cone pin lateral wall is raised provided with transmission, and the cone pin outer wall between sliding pin and supporting plate is provided with spring, the two ends of spring
Bear against sliding pin lower end and the upper end of supporting plate.
Technical principle of the present utility model is as follows：When work, sliding pin is adjusted by cylinder first, by sliding pin
Upper surface is adjusted to below the upper surface of workbench, and workpiece then is placed on into the upper of workbench, makes the positioning hole of workpiece with leading to
Hole correspondence.Then start cylinder to move up cone pin, sliding pin is upward together with cone pin under the action of the spring first
Move into positioning hole, until the upper surface of driving section is contacted with the lower surface of workbench, the transmission of cone pin during this
Projection is all the time in the bottom of drive cavity.Cylinder is continued to move up, and the transmission projection of cone pin is moved to from the bottom of drive cavity
The top of drive cavity, will appear from the upper end of cone pin outwardly against bulge, bulge produces expansion and then to fixed during this
The locking of position hole.The positioning to workpiece is completed above.
When needing to take out sliding pin from positioning hole, start cylinder and move down, also due to the elastic force of spring,
Cone pin slide downward first in sliding pin, contacts the extruding to bulge.Then cone pin is downwards by sliding pin moving belt
Dynamic, final sliding pin takes out from the positioning hole of workpiece.Can be with quick lock in workpiece, while protecting alignment pin not damaged by workpiece
It is bad.
The beneficial effects of the utility model are as follows：In position fixing process, sliding pin first can be located in through hole, then by sliding pin
Put in positioning hole, will not interfere, improve the sliding pin life-span.Whole process can be realized as only with a cylinder,
During cone pin is moved up and down, sliding pin is driven to extend upward through hole.
Further, sliding pin excircle is provided with slip cap, and the two ends of slip cap are connected with workbench and supporting plate respectively, right
Sliding pin is oriented to, and improves the stability in sliding process.
