Abstract

Disclosed is a novel adjustable and durable V-shaped positioning device, wherein, wear-resistant alloy bars that can be adjusted laterally are embedded into the upper end and the lower end of a V-shaped groove laterally, a workpiece is not in direct contact with the surface of the V-shaped groove, and is in point contact with the alloy bars. When a certain point of the alloy bars is worn, screws can adjust the alloy bars to move laterally for avoiding worn points, therefore, the alloy bars can be used repeatedly, and the service life of the V-shaped positioning device can be greatly extended. The positioning device is applied to a PCB micro-bit detecting device as well as other V-shaped groove structures.

Description

Adjustable and durable V type positioning apparatus

Technical field:

The V-type locating device of using when the utility model 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.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 adopted in the utility model 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 beneficial effects of the utility model are: can improve V-type positioner service life, and simple in structure, easy to use, joint The cost-saving. Usefulness when being not limited only to detect the PCB microbit also extends to all similar V-type positioners.

Claims

1, a kind of adjustable and durable V type positioning apparatus is characterized in that: V-type groove upper and lower side and V-type groove vertical direction embed adjustable wear-proof alloy stick.

2, adjustable and durable V type positioning apparatus according to claim 1 is characterized in that: can alloy bar laterally be moved by screw adjusted.

3, adjustable and durable V type positioning apparatus according to claim 1 is characterized in that: use the high hardness wear-resisting alloy bar, hardness＞HRA 90, and smooth finish＜Ra 0.2.
