Abstract
The utility model discloses a boring collet chuck of minor axis has solved current collet chuck and pressed from both sides the problem that tight reliability is poor, positioning accuracy is poor when carrying out minor axis drilling. It includes main shaft and the chuck that the axial connected gradually, two clamp splices setting up including the symmetry of chuck, two positions that the clamp splice is relative set up and are used for pressing from both sides the V -arrangement groove of getting the work piece, lateral part at the clamp splice is provided with the drill bit window that communicates the V groove along radial direction. The utility model discloses a boring collet chuck of minor axis is through the cooperation of main shaft, chuck, V -arrangement groove, drill bit window etc for collet chuck gets that the minor axis work piece adds reliability height in man -hour, positioning accuracy is high pressing from both sides, has simple structure, low in manufacturing cost's characteristics in addition.
Description
Technical field
The utility model relates to mechanical cold working equipment, is particularly a kind ofly mainly used in the boring fixture of the shorter axis body of length.
Background technology
Collet commonly uses fixture as a kind of lathe, has production low cost, advantage that clamping workpiece efficiency is high.Existing standard collet, as automatic drilling machine processing minor axis fixture, has following shortcoming:
One, minor axis clamping reliability is poor: drilling position need be outside at chuck, but minor axis is shorter because clamping, and cause chucking power unbalanced, one-sided stressed during boring, workpiece easily tilts, and causes Drill Crack and workpiece damage;
Two, minor axis positioning precision is poor: boring sites in curing is comparatively near according to retaining part, and iron filings easily enter chuck elastic groove, causes Workpiece fixing inaccurate unreliable with clamping, cannot meet automatic processing request.
Utility model content
In order to overcome above-mentioned existing technological deficiency, the purpose of this utility model is: provide that a kind of minor axis clamping reliability is high, positioning precision is high and the boring collet of the simple minor axis of structure.
In order to achieve the above object, the utility model is achieved through the following technical solutions: the boring collet of minor axis, comprise the main shaft and chuck that axially connect successively, described chuck comprises symmetrically arranged two fixture blocks, and the position that two fixture blocks are relative arranges the V-shaped groove being used for gripping workpiece; The drill bit window being communicated with V groove is radially provided with at the sidepiece of fixture block.
The fixture block part arranging drill bit window does skiving process, makes the porch of drill bit window press close to V-shaped groove.
The cell wall of described V-shaped groove is provided with anti-skidding lines.
The beneficial effects of the utility model are: the boring collet of minor axis of the present utility model, by the cooperation of main shaft, chuck, V-shaped groove, drill bit window etc., make collet gripping minor axis workpiece carry out adding man-hour reliability high, positioning precision is high, and has that structure is simple, the feature of low cost of manufacture.Because the fixture block part arranging drill bit window does skiving process, make the porch of drill bit window press close to V-shaped groove, drilling cuttings can be carried out with shorter drill bit, improve stability, ensure that reliability and the precision of the gripping adding man-hour.Cell wall due to described V-shaped groove is provided with anti-skidding lines, improves the reliability of gripping, improve the machining accuracy of product.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described, but protection domain of the present utility model is not limited to the following stated.
As shown in Figure 1 to Figure 3, the boring collet of minor axis of the present utility model, comprise the main shaft 1 and chuck 2 that axially connect successively, described chuck 2 comprises symmetrically arranged two fixture blocks, and the position that two fixture blocks are relative arranges the V-shaped groove 3 being used for gripping workpiece 5; The drill bit window 4 being communicated with V groove 3 is radially provided with at the sidepiece of fixture block.The boring collet of minor axis of the present utility model, by the cooperation of main shaft 1, chuck 2, V-shaped groove 3, drill bit window 4 etc., make collet gripping minor axis workpiece 5 carry out adding man-hour reliability high, positioning precision is high, and has that structure is simple, the feature of low cost of manufacture.
As preferably, the fixture block part arranging drill bit window 4 does skiving process, makes the porch of drill bit window 4 press close to V-shaped groove 3, can carry out drilling cuttings, improve stability with shorter drill bit, ensure that reliability and the precision of the gripping workpiece 5 adding man-hour.It should be noted that, the fixture block part arranging drill bit window 4 does skiving process, in order to easy to process, generally refers to that a tangent plane along parallel main axis 1 axial direction coordinates a tangent plane radially to carry out the process of excision skiving.
As preferably, the cell wall of described V-shaped groove 3 is provided with anti-skidding lines, improves the reliability of gripping, improve the machining accuracy of product.
As one preferred embodiment, in use, drill bit 9 is arranged on drill jig 8 the utility model, and main shaft 1 is arranged on collar bush 6, also be provided with the guiding drill jig 7 facilitating drill jig 8 to advance in the outside of collar bush 6, the position of described drill bit 9 is corresponding with the position of drill bit window 4.It should be noted that the stability in order to improve drill bit 9, being also provided with corresponding drill bushing 10.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
