Description
Technical field
The utility model relates to digit ctrol machine tool field, espespecially a kind of pilot hole mechanism.
Background technique
Existing drill spindle mechanism position error is larger, and deviation occurs in the position that will lead to hole in drilling, causes to produce
Product do not meet production requirement, cause the increase of production cost.
Utility model content
To solve the above problems, the utility model provides a kind of pilot hole mechanism that borehole accuracy is high.
To achieve the above object, the utility model adopts the following technical scheme is: a kind of pilot hole mechanism, including master
Axle bed and guide holder, the spindle drum two sides are equipped with upper and lower adjustment mechanism, and the guide holder is removably mounted at adjustment up and down
In mechanism, the guide holder is equipped with guide sleeve, and the guide sleeve passes through the tool position on upper and lower adjustment mechanism and spindle drum
Mutually with one heart.
Preferably, the adjustment mechanism up and down includes driving device, bottom plate, slide plate, and the bottom plate is individually fixed in master
The two sides of axle bed, the bottom plate are fixed with sliding block, and the slide plate is equipped with sliding rail, and the driving device driving slide plate makes sliding rail
It is moved up and down along sliding block.
Preferably, the two sides of the spindle drum are respectively equipped with side plate, and the bottom plate is fixedly connected by screw with side plate.
Preferably, the driving device is hydraulic cylinder device.
Preferably, the spindle drum is equipped with main shaft, and the cutter is located on main shaft.
The utility model has the beneficial effects that: guide holder moving up and down with slide plate, makes cutter be directed across guiding
Set, guide sleeve is consistent with the concentricity of cutter, improves the borehole accuracy of cutter.
Detailed description of the invention
Fig. 1 is the top view of the utility model.
Fig. 2 is the front view of the utility model.
Description of symbols: 1. spindle drums；11. main shaft；12. cutter；13. side plate；2. bottom plate；21. sliding block；3. slide plate；

Specific embodiment
Please refer to shown in Fig. 1-2, the utility model about a kind of positioning and guiding mainshaft mechanism, including spindle drum 1, bottom plate 2,
Slide plate 3, guide holder 4 and driving device, the spindle drum 1 is interior to be equipped with main shaft 11, and the main shaft 11 is equipped with cutter 12, the master
The two sides of axle bed 1 are respectively equipped with side plate 13, and two pieces of bottom plates 2 are respectively provided on side plate 13, and the side of the bottom plate 2, which is equipped with, to be slided
Block 21, the side of the slide plate 3 are equipped with sliding rail 31, and two pieces of slide plates 3 are slidably connected to divide by sliding rail 31 and sliding block 21
It is not slidably installed on bottom plate 2 not up and down, the driving device and slide plate 3 are sequentially connected, and the guide holder 4 is connect with two pieces of slide plates 3, institute
It states and is equipped with guide sleeve 41 in guide holder 4, keep guide sleeve 41 consistent with the concentricity of cutter 12 by the movement of slide plate 3.
Preferably, the driving device is hydraulic cylinder device.
The utility model by driving device drive slide plate 3 moved up and down relative to spindle drum, thus make guide sleeve 41 with
The axis of cutter 12 is in same position, improves the axial precision of guide sleeve 41 Yu cutter 12, and cutter 12 is directed across guiding
Set 41 drills, and improves the borehole accuracy of cutter 12.
Embodiment of above is only that preferred embodiments of the present invention are described, not to the utility model
Range be defined, under the premise of not departing from the spirit of the design of the utility model, this field ordinary engineering and technical personnel to this
The various changes and improvements that the technical solution of utility model is made should all fall into the guarantor that claims of the utility model determine
It protects in range.
