Abstract

The utility model provides a high-precision abutting and pressing automatic-release positioning dual-bore drill, which is capable of abutting and pressing a drilling workpiece and automatically returning. A positioning pin coaxial to a spindle is downwardly positioned in the middle of a drill plate. The dual-bore drill has the advantages that 1 special clamping is not needed, a drill bit is automatically clamped by a spring during downward movement, a part is automatically separated from a fixture after drilling, and detachment is omitted so that efficiency is improved, and 2 the part is positioned by the central positioning pin before two holes are drilled, the positions of the two small holes relative to a central hole are ensured, and the dual-bore drill is compact in structure and low in manufacturing cost.

Description

High accuracy compresses self-putting down location diplopore and bores
Technical field:
The utility model relates to a kind of diplopore and bores, and relates in particular to a kind of high-precision can compressing and drills can automatically reset high accuracy compressing self-putting down location diplopore and boring of workpiece.
Background technology:
Be difficult to guarantee the position degree of relative centre bore when traditional diplopore is drilled in boring, the position degree of two apertures can not get guaranteeing.
The utility model content:
The purpose of utility model: cheap for a kind of compact conformation is provided, part can guarantee that the high accuracy of the position of two relative centre bores of aperture compresses self-putting down location diplopore brill by the alignment pin location at center.
In order to reach as above purpose, the utility model is taked following technical scheme: alignment pin is coaxial with main shaft, and it is positioned at the middle part on the bushing plate down.
Adopt as above the high accuracy of technical scheme to compress self-putting down location diplopore and bore, have following technological merit:
1. do not need special clamping, in the drill bit folding process, clamp by spring automatically, boring finishes, and part breaks away from frock automatically, has removed dismounting from, and efficient improves.
2. two holes are before drilling, and part has guaranteed the position degree of two relative centre bores of aperture by the alignment pin location at center.
Compact conformation, cheap.
Description of drawings:
In order to further specify the utility model, further describe below in conjunction with accompanying drawing:
Accompanying drawing is the structural representation of utility model:
Fig. 1 is the result schematic diagram of boring
Fig. 2 is the utility model structural representation
Wherein: 1. main shaft; 2. headstock; 3. drill bit; 4. guide pillar; 5. bushing plate; 6. workpiece; 7. alignment pin; 8. workbench.
The specific embodiment:
Below in conjunction with accompanying drawing an embodiment of the present utility model is described, present embodiment does not constitute restriction of the present utility model:
The utility model is taked following technical scheme: alignment pin 7 is coaxial with main shaft 1, and it is positioned at the middle part on the bushing plate 5 down.
Adopt as above the high accuracy of technical scheme to compress self-putting down location diplopore and bore, have following technological merit:
1. do not need special clamping, in drill bit 3 folding processes, clamp by spring automatically, boring finishes, and part breaks away from frock automatically, has removed dismounting from, and efficient improves.
2. two holes are before drilling, and part has guaranteed the position degree of two relative centre bores of aperture by alignment pin 7 location at center.
3. compact conformation is cheap.
Drill jig of the present utility model can be realized the diplopore drilling of high precision position requirement.It is a special tooling by design, the composition that then bushing plate is fixed in the above, during work, workpiece is by alignment pin 7 location, the action that utilizes main shaft to descend drives the spring compression workpiece of both sides, drilling can realize auto-reset function after finishing, and clamping workpiece is simple, thereby high efficiency, precision is good, can improve effect 2-4 doubly than common driller, and the position degree precision of diplopore brings up to 0.03 by original 0.1 in addition.
Fig. 1 is the result schematic diagram of boring
As seen, two borings are around the strict symmetry of center hole.
Fig. 1 is the utility model structural representation
Workpiece is by alignment pin 7 location, and the action that utilizes main shaft to descend drives the spring compression workpiece of both sides, and drilling can realize auto-reset function after finishing.
