Description
Technical field
The utility model relates to a kind of screw rod, is specifically related to a kind of screw rod that is applicable to that three-coordinates measuring machine air supporting piece is fixing.
Background technique
At present, screw rod is that the air supporting piece is fixed to the main fixed structure on the three-coordinates measuring machine.In the position of needs adjustment air supporting piece, normally change the position of air supporting piece through the position of adjusting screw rod.Yet existing screw rod; The unsuitable air supporting piece that is used for fixing three-coordinates measuring machine; Because in the position of adjustment screw rod, inevitably can drive the air supporting piece and move along the radial direction of screw rod, increased difficulty for the position of adjustment air supporting piece; Waste time and energy, and had a strong impact on the precision of three-coordinates measuring machine.
The model utility content
For solving the deficiency of existing technology, the purpose of the utility model is to provide a kind of screw rod that is applicable to that three-coordinates measuring machine air supporting piece is fixing, and the air supporting piece fixing through this screw rod makes things convenient for adjusted position.
In order to realize above-mentioned target, the utility model adopts following technological scheme:
A kind of screw rod that is applicable to that three-coordinates measuring machine air supporting piece is fixing is characterized in that, begins to comprise successively from an end that is connected with the air supporting piece: be used for constituting connecting head, changeover portion, external thread section, the tail end that is connected with the air supporting piece; Aforementioned connecting head is the spherical or spherical shape that become dissectd by the plane.
The aforesaid screw rod that is applicable to that three-coordinates measuring machine air supporting piece is fixing is characterized in that aforementioned changeover portion begins to comprise successively two first changeover portion and second changeover portions that form step each other from an end that links to each other with connecting head.
The aforesaid screw rod that is applicable to that three-coordinates measuring machine air supporting piece is fixing is characterized in that, aforementioned connecting head is dissectd the shape that become for spherical by the plane, is formed with step between aforementioned first changeover portion and the aforementioned connecting head.
The aforesaid screw rod that is applicable to that three-coordinates measuring machine air supporting piece is fixing is characterized in that, is formed with step between aforementioned second changeover portion and the aforementioned external thread section.
The aforesaid screw rod that is applicable to that three-coordinates measuring machine air supporting piece is fixing is characterized in that aforementioned connecting head, changeover portion, external thread section, tail end are coaxial rotary structure.
The aforesaid screw rod that is applicable to that three-coordinates measuring machine air supporting piece is fixing is characterized in that the radius of aforesaid tail end is less than the radius of aforementioned external thread section, and aforementioned tail end end is provided with the interior angle screw.
The usefulness of the utility model is: screw rod has sphere or spherical is dissectd the connecting head of the shape that is become by the plane, in rotary screw, is unlikely to make the air supporting piece that is connected with connecting head to move radially; The tail end of screw rod has the interior angle screw, conveniently screws screw rod; Whole screw rod becomes rotary structure, guaranteed the smoothness of screw rod when screwing to the full extent, has guaranteed that indirectly the air supporting piece is in the radial direction position stability.
Description of drawings
Fig. 1 is the structural representation of a specific embodiment that is applicable to the screw rod that three-coordinates measuring machine air supporting piece is fixing of the utility model;
The implication of reference character among the figure:
The 1-connecting head, 2-changeover portion, 21-first changeover portion, 22-second changeover portion, 3 external thread sections, 4 tail ends.
Specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done concrete introduction.
With reference to Fig. 1, the utility model be applicable to the screw rod that three-coordinates measuring machine air supporting piece is fixing, comprising: connecting head 1, changeover portion 2, external thread section 3 and tail end 4.
As a kind of preferred version, when screwing screw rod, in order to guarantee the smoothness of the air supporting piece that screw rod and screw rod connect to the full extent, screw rod is a rotary structure.As shown in Figure 1, the connecting head 1, changeover portion 2, external thread section 3 and the tail end 4 that constitute screw rod are coaxial rotary structure.Certainly, except that connecting head 1 and external thread section 3 are necessary for the rotary structure, changeover portion 2 can be other structures except that rotary structure with tail end 4, is not limited to rotary structure.For convenient explanation, introduce respectively to each section of the screw rod with rotary structure below.
Connecting head 1 is dissectd formed shape for spherical or spherical by the plane, directly is connected with the air supporting piece (not shown) with corresponding recesses.
The agent structure of screw rod is an external thread section 3, and the outside thread that external thread section 3 has matches with the carrier that is used for fixing screw rod (not shown) with internal thread, and screw rod is fixed on the carrier.
Be provided with changeover portion 2 between connecting head 1 and the external thread section 3, because connecting head 1 volume is less, and the volume of external thread section 3 is relatively large, so between is provided with a changeover portion 2.For attractive in appearance; And the cost of saving the manufacturing screw rod; Changeover portion 2 be divided into again cylindrical first changeover portion 21 of the less one-tenth of diameter and diameter bigger become cylindrical second changeover portion 22, can be fixed on the carrier in order to make screw rod, the radius of second changeover portion 22 is less than the radius of external thread section 3.First changeover portion 21 directly links to each other with the less relatively connecting head 1 of volume, and second changeover portion 22 directly links to each other with the relatively large external thread section 3 of volume.So, between the connecting head 1 and first changeover portion 21, be formed with step, between first changeover portion 21 and second changeover portion 22, be formed with step, between second changeover portion 22 and external thread section 3, also be formed with step.
Screwing screw rod for ease, be provided with interior angle screw (not shown) in the end of the tail end 4 of screw rod, is to save material, and the radius of tail end 4 is less than the radius of external thread section 3.
Need to prove that the foregoing description does not limit the utility model in any form, all employings are equal to the technological scheme that mode obtained of replacement or equivalent transformation, all drop in the protection domain of the utility model.
