Abstract
The invention relates to a novel tunable and durable V-shaped positioning device; a wear-resisting alloy bar which can be adjusted transversely is transversely embedded in the up and down end of a V-shaped groove, and a workpiece is not directly contacted with the V-shaped groove face but with the alloy bar in a point contact way. When one point of the alloy bar is worn, the worn point can be avoided by adjusting the alloy bar to move transversely by a bolt, so that the alloy bar can be repeatedly used and the service life of the V-shaped positioning device is greatly prolonged. The positioning device is not only suitable for a PCB microbit detecting device but also suitable for other V-shaped groove structures.
Description
Technical field:
The V-type locating device of using when the present invention relates to a kind of PCB of detection microbit also is applicable to other V-type groove structures.
Background technology:
At present, the locating device of using when general PCB microbit detects is common V-type groove, and drill bit directly contacts with the V-type groove face.It has a very big shortcoming is easy wearing and tearing, repair cumbersome again and precision is difficult to guarantee that the cost that renews is higher, therefore presses for a kind of durable locating device that can guarantee precision for a long time.
Summary of the invention:
Wear and tear, repair problems such as difficulty easily in order to overcome common V-type groove, the utility model provides long locating device of the simple and easy adjusting of a kind of energy, life-span.
The technical solution used in the present invention is: laterally embed wear-proof alloy stick at V-type groove upper and lower side, workpiece does not directly contact with the V-type groove face, but carries out contacting with alloy bar.When alloy bar a bit weares and teares, can alloy bar laterally be moved, avoid wear point, so alloy bar can repeatedly use repeatedly, improve V-type locating device serviceable life by screw adjusted.
Description of drawings:
Fig. 1 is a V-arrangement locating device front elevation, and Fig. 2 is a vertical view.
1 is V-arrangement locating device pedestal among the figure, and 2 is alloy bar, and 3 is the alloy bar fixed block, and 4 is set screw.
Embodiment:
Alloy bar 2 is embedded in the alloy bar fixed block 3, is contained on the V-arrangement locating device pedestal with set screw 4.
When certain a bit wore and tore when alloy bar 2, by set screw 4, may command alloy bar fixed block 3 moved, thereby the contact point of alloy bar and drill bit workpiece is changed, and whole V-arrangement locating device can reach the purpose that increases the service life as new having used again.
Beneficial effect:
The invention has the beneficial effects as follows: can improve V-type positioner service life, simple in structure, easy to use, save into This. Usefulness when being not limited only to detect the PCB microbit also extends to all similar V-type positioners.
